Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a feed quantitative packaging device. Background Art

[0002] Feed is the general term for the food of farmed animals. More narrowly, generally, feed mainly refers to the food of animals farmed in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils and fats, meat and bone meal, grains, and feed additives.

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

[0004] Before the feed bagging process, it is necessary to pre-screen the feed, screen out the feed particles that are too large and reprocess them. Then, the screened feed is put into a storage bag for collection, and then the bag is sealed and sold externally. In the actual working process, screening and bagging cannot be carried out simultaneously, resulting in a complex operation procedure and low bagging efficiency of the feed. In addition, after the feed is bagged, it is necessary to weigh it to make the feed weight in each packaging bag basically the same. The operation process is cumbersome and time-consuming, so it is urgent to design a feed quantitative packaging device to solve the above problems. Content of the Utility Model

[0036] Working process:

[0037] The bag mouth of the packaging bag is opened and mounted on the discharge port of the bagging barrel 3, and the bag clamping cylinder 2-2 in the bag clamping device 2 is started to retract its piston rod, driving the two sets of clamping belts 2-6 to close and thus clamp the bag mouth of the packaging bag on the discharge port of the bagging barrel 3; then the discharge valve plate 14 is slid upward to open the discharge port of the storage hopper 13, and the vibration motor 12 and the driving motor in the material transmission device 8 are started to drive the feeding auger in the spiral transmission component 8-1 to rotate; the material in the storage hopper 13 falls from the discharge port to the screening net 18 installed on the screening box 17, and is vibrated. Under the vibration of the motor 12, the screening net 18 can screen the materials that fall onto it, and the feed that meets the particle size requirements falls onto the receiving hopper structure 9, and is transmitted to the discharge box 8-2 under the action of the feeding auger in the spiral transmission component 8-1. The feed that falls into the discharge box 8-2 falls into the packaging belt through the drop hopper 7, the discharge hopper 6-2 (the discharge port of the discharge hopper 6-2 is in an open state at this time) and the bagging barrel 3, and then the bagging operation is performed. During the bagging process, the weighing sensor 4-2 can detect the weight of the feed in the packaging bag in real time;

[0038] When the material in the packaging bag reaches the rated packaging weight, the discharge cylinder 6-1 retracts, driving the arc valve plate 6-3 to swing downward to close the discharge port of the discharge hopper 6-2, and at the same time controls the drive motor in the material transmission device 8 to stop running. When the bagging operation is performed again, the drive motor in the material transmission device 8 and the discharge cylinder 6-1 are restarted;

[0039] After completing the above bagging operation, control the clamping cylinder 2-2 in the bag clamping device 2 to start. Its piston rod extends to drive the two clamping belts 2-6 to swing outward away from the bagging cylinder 3, thereby releasing the clamping of the bag mouth of the packaging bag by the clamping belt 2-6 and the bagging cylinder 3, so that the bottom of the packaging bag touches the ground. During this process, the staff can hold the packaging bag by hand to prevent the packaging bag from tipping over.
