[0001] The present application relates to the technical field of feed sealing, and in particular to a feed bag sealing mechanism. Background Art
[0002] Feed sealing machine is a machine that seals bags filled with feed. After the product is put into the packaging bag, in order to keep the product sealed and preserved, maintain the quality of the feed and avoid the loss of feed, the packaging container needs to be sealed. This operation is completed on the sealing machine, and the sealing machine often requires manual assistance during operation.
[0003] After searching the publication number: CN215922726U, a feed bag sealing machine is disclosed. The conveyor belt drives the feed bag to move, and the bag mouth will move on the surface of the contact block. At this time, it will contact the heating plate and drive the heating plate to rotate. Under the cooperation of the conductive block and the brush, even if the heating plate rotates, it will not cause the line to be entangled and fail to work normally. In this way, the heating plate will initially seal the bag mouth. The contact port is designed to be an arc as a whole, so that the contact port will initially fold the front end of the feed bag, and as the feed bag is transported, it will be completely folded in half under the action of the folding groove. In this way, as the folded feed bag is continuously transported, the feed bag will be sealed under the action of the bag sewing machine.

[0005] This device is only applicable to feed bags of fixed size, and its practicality is average. In addition, when the top of the feed bag is folded, the arc-shaped contact port will cause bulges on both sides of the bag and gaps to appear, thereby reducing the sealing effect.
