baler with wrapper

When you hear “baler with wrapper?”, many people immediately think - well, I made a bale, wrapped it in film, and that’s it. But in practice, the difference between simply wrapping it and properly, securely packing it is like between raw and finished hay. And this difference often comes out later, during storage, when you start to disassemble the bales and see where the mold has grown, and where the hay is like new. For a long time I thought that the main thing was compaction density, and the winding was the final touch. Until I encountered the fact that, due to a crooked winding, half the batch had to be put on the mat - an expensive pleasure.

Where is the catch in ?integrated? systems

Now many manufacturers, especially new ones from China, like to talk about integrated intelligent systems. Take, for example,baler with wrapper, they put a bunch of sensors and a controller on it, they call it a “smart agricultural complex”. Sounds solid. But in reality it often turns out that the mechanics themselves are the weak link. Especially the film tension and supply units. I have seen devices where the electronics show ideal parameters, but the film lays with overlaps or, conversely, with holes. And this is where it is important that the company not just assemble lines, but delve deeply into the process. How, let's say,Hulunbuir Machinery Manufacturing Company ?Jiujia?(their website is https://www.cn-fascar.ru). They position themselves as a modern integrated enterprise, and what is important is that they combine R&D, production and service. These are not just words. When developers themselves go to the fields and see how their equipment works in real conditions, and not in a test workshop, you can feel it in the details. By the way, their description directly states: “combining research and development, production, sales and service?” Forbaler with wrapperThis approach is critical because service must be fast and spare parts must be available. It’s not the same story when you wait a month for a gear from overseas.

Specifically for the wrapper: many people underestimate the role of the tension control system. It should not just be mechanical with a spring, but adaptive, taking into account the speed of movement of the unit, the humidity of the film (yes, it also affects!), and even the air temperature. In the summer, in the heat, polyethylene becomes more elastic, and if the tension is not adjusted, the bale will turn out to be “loose.” along the winding, it will sag. In winter, on the contrary, the film becomes tanned, and too much tension can lead to tears. Good systems can compensate for this, but they are usually more expensive. And this is where the line between a cheap and reliable solution is visible. Cheap models often suffer from this - you set it up once and that’s it, there is no adjustment. It works only in ideal conditions, which do not exist in the field.

Another point is the winding mechanism itself, the rotation of the bale. There are systems with constant rotation, and there are systems with reverse rotation, when the bale makes several turns in one direction, then the carriage with the film moves and the rotation goes in the other direction. The second option, in my experience, gives a more uniform and dense coating, especially for large diameter bales. But the design is also more complex, with more wearable parts. I saw how at one of the demonstrationsHulunbuir company ?Jiujia?showed exactly the reverse system on herbaler with wrapper. They explained that this provides more reliable protection from moisture along all the seams of the bale. It sounded convincing, but I am always a skeptic - I asked to show it on a device worn out after the season. They showed that the gaps were within normal limits, the components were easy to service. This is already a serious argument.

Press density and winding: what comes first?

People often argue about what is more important. My answer is that they are inseparable. You can make a bale of ideal density, but if the winding has air pockets, moisture will get inside and a debate will begin. Conversely, even the highest quality film will not save a loose bale, which will fall apart during transportation. The key is to synchronize the operation of the pressing chamber and the winding unit. A lot depends on hydraulics and electronics here. I saw unsuccessful attempts to save money on the controller when the wrapper started working without waiting for the bale to be completely formed and tied with twine. The result is a lump of hay, partially wrapped in film, a waste product. A good system first finishes forming and tying, pauses, secures the bale, and only then starts the film carriage. This seems like a small thing, but on a scale of hundreds of bales a day, it’s such a “trifle?” determines the defect rate.

From practice: we had a case where we bought a used onebaler with wrapperEuropean production. Everything seemed to be in order, but the percentage of bales with broken geometry was high. They began to figure it out. It turned out that the previous owner had “tuned” hydraulics, increased the pressing speed, but did not reconfigure the sensors for the wrapper. It simply did not have time to work correctly. I had to search for the original documentation for a long time and return the factory settings. Moral: in such a technique, everything must be balanced from the factory. Independent ?improvements? most often lead to problems. Therefore, when you choose a new manufacturer, you look at how integral the system is, and not assembled from components purchased externally. MentionedHulunbuir Machinery Manufacturing Company ?Jiujia?, judging by their materials, relies on its own development and full cycle. For me, this is a plus, because the responsibility for connecting the units lies with one manufacturer, and is not attributed to the “jamb of the hydraulics supplier.”

More about density. It should not always be the maximum possible. There is one density for alfalfa, and another for grain-legume mixtures. A bale of wet hay that is too dense is guaranteed to have mold inside, as it will not “breathe?” even with perforated film. Goodbaler with wrappershould allow flexible adjustment of this parameter, and the settings should be stable and not be affected by vibration. In cheap models, the adjustment mechanism is often not made very well, there is play, and by the end of the day the density “floats away”. It's easy to check - make ten bales in a row, then weigh and measure the volume. The spread should not exceed 5-7%.

Film: you can’t save money, you can’t overpay either

The topic is separate and painful. The quality of the film is 50% of the success of the winding. But there is a trap here: many people think that the thicker the film, the better. Not always. A thick but inelastic film may not fit well around the bale, especially if it is not an ideal shape. A thin one, but with good stretch and a UV stabilizer, often performs better. It is important to look at the compatibility of the film with a specific wrapper model. Some machines, especially those with powerful tension systems, are designed for film of a certain tensile strength. If you put a thinner one, it will tear. If it is thicker, it may overload the feed mechanism. Equipment manufacturers usually make recommendations, and you should listen to them. On the same site https://www.cn-fascar.ru, by the way, I saw that?Jiujia?offers its recommendations on consumables, down to specific brands of film. This is the right approach and reduces risks for the end user.

How many layers to wind? Standard - 6-8. But again, it depends on where and how the bale will be stored. If outdoors, and even in a region with strong winds and sun, it is better to use 8 or even 10 layers, but with a thinner film to save money. If under a canopy, you can do 6. Some modern wrappers can automatically change the number of layers depending on the specified program. Convenient, but another point of potential failure. Personally, I prefer simpler and more reliable mechanical meters with manual adjustment. Less electronics means fewer problems in the field. Although, I understand that the trend towards automation is inevitable.

And about the process itself. It is important that the film is fed from the roll without jerking. This needs to be monitored. Clogging of the guide rollers with straw or dirt is a common cause of uneven winding. Good designs take this into account - the rollers have protective covers or a self-cleaning design. Trifle? No. Because stopping every half hour for cleaning is a waste of time and fuel. When I studied technology fromHulunbuir company ?Jiujia?, noticed that in their videos they emphasize ease of maintenance in the field and quick access to key components. For me this is more important than chrome handles.

Service and “long-lasting” details

Anyone, even the bestbaler with wrapperbreaks. The question is how often and how quickly it will be repaired. This is where the seriousness of the manufacturer is checked. Those who have spare parts warehouses and trained service engineers in the region immediately take the lead. The story of waiting a month for a spare part kills all the benefits of the purchase. A company that integrates production, sales and service as statedHulunbuir company ?Jiujia?, theoretically should control this chain better. But theory is theory, but in reality you need to ask real users in your region. I always do this.

Which components break most often? In the wrapper: carriage shaft bearings, film cutting knife (dull and bent), gear teeth in the bale rotation mechanism. In the press: pressing chamber springs, belts, hydraulic cylinders. The reliability of these parts directly depends on the metal and heat treatment. Cheap analogues made from raw steel fail many times faster. Therefore, when choosing equipment, you need to look not only at the price, but also at the warranty for these specific components. It often happens that the device itself is guaranteed for a year, but the hydraulic system is only three months. This is a wake-up call.

From personal experience: once they installed “step-children” bearings in the tension unit, saved money. As a result, they fell apart in the midst of preparation, plus they damaged the shaft. Downtime and repairs cost more than all the original bearings for five years. Since then, as a matter of principle, I only use consumables recommended by the manufacturer. Yes, more expensive. But in the end it’s cheaper.

Bottom line: what to look for when choosing?

So, to summarize my sometimes bitter experience.Baler with wrapper- these are not two devices in one, but a single organism. When choosing, you need to evaluate: 1) Synchronization of the operation of the pressing and wrapping parts. Ask to show them in work on real material, to make a dozen bales. 2) Quality and adaptability of the film tension system. 3) Ease of maintenance and access to key components for cleaning and replacement. 4) Availability of a service network and spare parts warehouse within reasonable accessibility. 5) Manufacturer's recommendations for compatible materials (film, twine).

And of course, look at the manufacturer as a whole. If the company is like the sameHulunbuir Machinery Manufacturing Company ?Jiujia?, claims a full cycle from development to service, it’s worth checking out. Look at the reviews, if possible, go to the production or demo site. Because ultimately, you are buying not just hardware, but a tool for stable and high-quality feed production. And a lot in the household depends on this tool. There are no trifles here. Every detail, every play, every algorithm of work is either saved food in the future or money down the drain. The choice, in general, is ours.
