Description

Technical Field

[0001] The utility model relates to the technical field of silage bag folding machines, in particular to a contraction limiting mechanism of a feeding 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 announcement number CN207957330U, which includes a mounting seat and a supply plate slidably mounted on the mounting seat; a horizontally arranged oil cylinder is fixed on the mounting seat, and the telescopic rod of the oil cylinder is fixedly connected to the supply plate; a fixed guide block is also provided on the mounting seat, and a guide hole is processed on the guide block, and a guide rod is slidably mounted in the guide hole; one end of the guide rod is fixedly connected to the supply plate; the supply plate includes a vertical straight plate and two arc plates symmetrically arranged at the upper and lower ends of the straight plate; a reinforcement portion is provided on the inner side of the straight plate; during the silage bag folding process, the feeding device is used to continuously open the silage bag, and the feeding device can move along the track of the silage bag folding machine to feed the supported silage bag forward to the fixed plate of the silage bag folding machine, which has the advantages of simple structure, smooth operation and transportation, etc.

[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] The existing device is provided with two oppositely arranged supply plates, and the silage bag is tensioned or loosened by the two supply plates moving toward and against each other in the lateral direction. After the supply plates move longitudinally to supply the silage bag into place, the two supply plates need to first move toward each other in the lateral direction to release the tension on the silage bag, and then the supply plates move longitudinally to the starting position. When the supply plates release the tension on the silage bag, the supply plates are affected by the cylinder drive and the retreat distance is too large, resulting in the supply plates being unable to support the silage bag, thereby reducing the supply efficiency of subsequent silage bags.

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

[0007] In view of the defects in the prior art, the utility model solves the problem that when the existing supply plate releases the tension on the silage bag, the supply plate is affected by the cylinder drive and retracts too far, resulting in the supply plate being unable to support the silage bag, thereby reducing the subsequent silage bag supply efficiency.

A control plate for switching the limit seat is provided on one side of the avoidance hole for vertical sliding, and a limit interval is formed between the control plate and the limit seat.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] By setting a limit seat between the supply plate and the mounting plate, and adjusting the extension length of the screw rod, the limit interval between the limit seat and the control plate can be adjusted, so that when the silage bag needs to be released from tension, the driving cylinder drives the supply plate to retract, and the supply plate drives the limit seat moving seat to move, and the limit seat will press against the control plate, thereby accurately controlling the movement stroke of the supply plate, so that the arc-shaped bag support plate can release the tension of the silage bag while supporting the silage bag, thereby ensuring the supply efficiency of subsequent silage bags;
