Description

Technical Field

[0001] The present invention relates to the technical field of canned food filling, and in particular to a filling device and method for producing canned pet food. Background Art

[0002] In the canned pet food production process, filling is a critical step in determining product quality and production efficiency. Existing automated filling equipment typically uses a conveyor belt and a rotating disk for intermittent conveying, completing quantitative filling at specific workstations.

[0003] However, this type of equipment still has some shortcomings when handling the filling of pet food mixed with meat chunks, fruit and vegetable particles: First, after the pet food falls into the filling box, it often accumulates unevenly due to gravity to form irregular protrusions, affecting the subsequent sealing process and packaging quality; second, due to the different particle sizes of pet food, it is easy to bridge or clog at the narrow discharge port. Once a blockage occurs, the subsequent filling box will not be able to receive enough material, resulting in an "empty box" or "insufficient box". Existing equipment usually lacks an effective online active unblocking mechanism and often requires manual cleaning after shutdown, which not only seriously interrupts production continuity, but also increases labor costs and defective product rates. Therefore, there is an urgent need to develop a pet can filling equipment with a self-homogenizing function during the filling process and an active anti-blocking and unblocking function for the feeding channel to solve the "empty box" problem caused by uneven material distribution and blockage, and to improve filling quality, production stability and automation level.

10. A filling method for canned pet food production, based on the filling equipment for canned pet food production according to any one of claims 1 to 9, comprising the following steps: S1, the filling box is transported by the conveyor belt 1 (102a) and is placed in the positioning groove (202a), and the positioning rotating disk (202), the feeding disk (203) and the feeding barrel (208) are intermittently driven to rotate by the stepping motor (201), and the filling box is driven to move intermittently by the positioning rotating disk (202); S2, the electric slide rail (404) cooperates with the connecting rod (405) to drive the opening and closing plate (406) to move back and forth, so that the pet food in the feeding barrel (403) falls into the feeding barrel (208), and then enters the filling box through the feeding barrel (208), and the same amount of pet food is intermittently added to the feeding barrel (403) through the quantitative feeding device, wherein the quantitative feeding device adopts existing general equipment; S3, when the positioning rotating disk (202) rotates intermittently, the flexible block (303) is tightly fitted to the outside of the filling box, and the filling box is driven to rotate by friction, so that the pet food in the filling box is evenly distributed; S4, when the filling box moves to the position just below the dredging head (506), the telescopic cylinder (503) cooperates with the movable plate (504) to drive the vertical rod (505) and the dredging head (506) to move up and down. The downward movement of the dredging head (506) is used to dredge the feeding barrel (208), thereby preventing the pet food from being blocked in the feeding barrel (208) and causing an "empty box" phenomenon. S5, the unblocked filling box is transferred to the next process via the conveyor belt 2 (102b).
