Description

Technical Field

[0001] This utility model relates to the field of pet food production screening technology, and in particular to a screening device for pet food production. Background Technology

[0002] In pet food production, screening equipment is a crucial step in ensuring product quality. It primarily separates sized pellets from non-sized pellets, debris, or foreign objects. Existing pet food screening equipment typically includes a casing and a material hopper inside. The bottom of the hopper opens to form a feeding channel, within which a rotating shaft has multiple circumferentially arranged feeding plates. As the shaft rotates, the feeding plates push the pet food towards the screen assembly below. Particles meeting the size requirements pass through the screen, while larger particles or foreign objects are intercepted, thus achieving grading and screening.

[0003] However, existing screen assemblies are typically fixed structures, meaning the screen remains stationary during the screening process. This design has the following drawbacks:

[0004] Low screening efficiency: Since the screen is fixed, the material passes through the screen only by gravity and the action of the push plate. Some particles tend to accumulate on the screen surface, which reduces the screening speed and affects the overall production efficiency. Utility Model Content

[0006] A screening device for pet food production designed for this purpose includes a housing and a material bin. The material bin is located inside the housing, and its bottom opening forms a feeding channel. A rotating shaft is rotatably mounted inside the feeding channel, and multiple material-pulling plates are arranged in a circumferential array along the shaft. A screen assembly is located inside the housing below the feeding channel and is movable vertically relative to the housing. The housing is equipped with a reciprocating moving module for driving the screen assembly to move vertically relative to the housing. A drive module is fixedly mounted on the housing and is used to simultaneously drive the rotating shaft to rotate and drive the reciprocating moving module to operate.
