Description

Technical Field

[0001] The utility model relates to the technical field of silage bag folding machines, in particular to a contraction driving mechanism of a supporting device for 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. The solution 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. During the folding of the silage bags, the folded silage bags can be supported, fixed and positioned, and the subsequent silage bags can be conveniently folded toward the surface of the folded silage bags, so that the folding of the silage bags can achieve better positioning, and the folded silage bags can be ensured to be more neat and orderly.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] Two supporting devices arranged opposite to each other are arranged on the existing device, and the folded silage bag is supported by the two supporting devices. During the folding process of the silage bag, as the number of folded layers increases, the thickness gradually increases, and it is necessary to reduce the distance between the two supporting devices. However, due to the influence of the contraction drive structure of the existing supporting device, not only is the structure complicated, but the stability of the supporting device during the contraction process cannot be guaranteed, thereby reducing the folding efficiency of the silage bag folder.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
