Description

Technical Field

[0001] The utility model relates to the technical field of silage bag folding machines, in particular to a middle contraction mechanism for a supporting device of a silage bag folding machine. Background Art

[0002] At present, there is a kind of plastic silage bag for farm animals on the market, which is mainly used for silage of livestock feed. Compared with other silage methods, bagged silage has the advantages of less labor, less waste, low cost and convenient operation. In particular, the fermentation effect of bagged green fodder is good and more conducive to livestock digestion and absorption. At present, small-sized bags with a length and width of 1-2 meters are commonly used in China, and they can be used directly without folding. However, there is a large silage bag used in conjunction with a filling machine on the international market, which is wider and can reach 80 meters in length. It can be put on the discharge port of the filling machine for use. The filling machine must walk and put the bag at the same time when filling. The general roll-shaped products cannot be used directly. It must be folded one ring after another, and the folding method is similar to a folding fan. Because it is ring-shaped and large in size, it is difficult to achieve manual folding without the help of a silage bag folding machine.

[0003] The prior art discloses a patent with a publication number of CN207810890U, which includes two symmetrically arranged fixed plates, which are used to fix the folded silage bags; it also includes a plurality of clamping devices and presser feet, the clamping devices are used to clamp the folded silage bags on the fixed plates; the presser feet are located between the two fixed plates and are used to tension the silage bags; the fixing system for the silage bag folding machine also includes a support portion arranged between the two fixed plates, the position of the support portion can be adjusted up and down, and the support portion is used to support the folded silage bags on the fixed plates. The utility model provides a fixing system for a silage bag folding machine, which can support, fix and position the folded silage bags during silage bag folding, and can also facilitate the subsequent silage bags to continue to be folded toward the surface of the folded silage bags, so that better positioning can be achieved in the folding of the silage bags one after another, and the folded silage bags can be ensured to be more neat and orderly.

[0004] The existing devices including the above patents gradually exposed the shortcomings of the existing technology as they were used, mainly in the following aspects:

[0005] The silage bag is supported by the supporting devices on both sides of the silage bag folder. During the folding process, the middle position of the silage bag is prone to drooping, which makes it impossible for the subsequently folded silage bag to be inserted into the previously folded silage bag. Therefore, a middle contraction mechanism is required to support the middle position of the silage bag. However, the support arm of the existing middle contraction mechanism is limited by the driving mode of the cylinder during use. During the feeding and lifting process, hard collision contact and over-travel are prone to occur, which reduces the efficiency of silage bag folding.
