Description

Technical Field

[0001] The utility model relates to the technical field of pet food processing, in particular to a pet food metal detection device. Background Art

[0002] Pet food is food specially provided for pets and small animals. It is a high-end animal food between human food and traditional livestock and poultry feed. Its main function is to provide the most basic nutrients required for life guarantee, growth and health for various pets. Pet food processing must go through raw material pre-treatment, batching, processing and molding, drying or ripening, sterilization, inner packaging (canning), metal detection, outer packaging and labeling, quality inspection and delivery. Among them, raw material acceptance, sterilization and metal detection are generally regarded as key control points in the production process.

[0003] In the prior art, a pet food metal detection device includes a conveyor belt, a metal detector disposed on the conveyor belt, and a push structure disposed on the conveyor belt; during the implementation of the device, the metal detector is used to detect the pet food containing metal. When the metal detector detects that the pet food contains metal, a signal is fed back to the push structure. When the pet food containing metal moves to the push structure, the push structure pushes it to transfer. The push structure in the device uses pneumatic or hydraulic means to complete the push action. It is arranged perpendicular to the conveying direction of the conveyor belt, resulting in a large layout range and space occupation. In addition, the push structure also includes a position sensor for detecting pet food containing metal. When the push structure executes a push command, it needs to be detected by the position sensor before it can proceed. There are many electrical signal feedbacks, and the push structure has a large lag in executing the push command. Once the position sensor detects a fault, it cannot execute the push action, resulting in a generally high cost of the push structure. Utility Model Content
