Description

Technical Field

[0002] Feed is a general term for food for raised animals. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] At present, more and more livestock are being raised. With the progress of society, the artificial breeding industry has developed greatly and the demand for breeding is increasing. The process of feed production includes raw material cleaning, crushing or grinding, mixing, granulation, drying and packaging. In order to facilitate use, improve feed utilization and reduce production costs, packaging is divided into two steps: bagging and sealing.

[0004] During the process of bagging feed, since the bags are relatively soft, most bagging and packaging machines need to be manually supported to carry out bagging and packaging operations. Manually supporting the bags is not only unstable, but also easily wastes a lot of labor, affecting the efficiency of the bagging operation. In addition, after the bagging operation is completed and the bag is released, the top of the bag will collapse and deform or even tilt, causing the feed in the bag to fall to the ground due to the deformation of the bag mouth or the overall tilt, resulting in feed waste.

After the two groups of bag clamping components 5-4 clamp the upper part of the packaging bag to close the packaging bag, the bag mouth clamp 6 is started to release its clamping on the bag mouth of the packaging bag, so that the packaging bag is separated from the bag mouth clamp 6. At this time, the bag holding device 4 clamps the middle part of the packaging bag to prevent it from tipping over. At the same time, the bag clamping device 5 clamps the upper part of the packaging bag, so that the bag mouth of the packaging bag is in a closed state, which prevents the feed in the packaging bag from falling out due to the deformation of the bag mouth of the packaging bag, thereby avoiding waste of feed.
