Description

Technical Field

[0001] The utility model belongs to the technical field of bagging equipment, in particular to a feed bagging machine. Background Art

[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] In the process of bagging feed, the packaging bag is usually put on the discharge hopper of the bagging machine body manually, and the feed falls from the discharge hopper into the packaging bag for packaging. During the packaging process, the staff needs to manually fix the packaging bag, that is, the staff fixes the position of the packaging bag by holding the bag mouth of the packaging bag, and this operation process is time-consuming and laborious; in addition, in the above-mentioned bagging process, the feed falls into the packaging bag from a high place, which is prone to dust, thereby affecting the entire working environment and further affecting the health of the workers; in addition, after the bagging is completed, because there is an error in the bagging of each bag of feed, the existing bagging machine cannot weigh the bagged feed in time after the bagging is completed. After the bagging is completed, the bagged feed needs to be moved to the other side for weighing, which leads to untimely weighing, reduces the bagging efficiency of the feed, and is very inconvenient to use. Therefore, it is urgent to design a feed bagging machine to solve the above problems. Utility Model Content
