Description

A kind of granular pet food sorting and conveying device

Technical field

The invention relates to the technical field of pet food production equipment, specifically a granular pet food sorting and conveying device.

Background technique

Pet food is food provided to pets and small animals. Its main function is to provide various pets with the most basic nutrients needed for life assurance, growth, development and health. It has comprehensive nutrition, high digestion and absorption rate, scientific formula, quality standards, convenient feeding and use, and can prevent certain diseases. Etc. In the production process of granular pet food, a sorting and conveying device is needed to sort and transport it. Sorting is the process of classifying granular food according to particle size. The sorting mainly uses sieve plates to allow the granular food to pass through. In the screening classification, the current sorting equipment has the problem of incomplete sorting. The main reason is that the food particles are accumulated in a single position in the sorting chamber during unloading. During sorting, some small particles will be discarded without being screened out. transportation situation.

In this regard, the Chinese invention patent with the authorization announcement number CN115138565A discloses a granular pet food sorting and conveying device. The sorting and conveying device includes a base. The two corners at the top of the base are respectively fixed to both sides of the bottom of the support base. Connection, support blocks are fixed on both sides of the top of the support base, the tops of the two support blocks are fixedly connected to both sides of the bottom end of the support plate, and a unloading mechanism is provided on the top of the support plate.

The baffle plate on the connecting shaft of the sorting and conveying device opens and closes intermittently. With the cooperation of the unloading plate connected to the unloading shaft, the pet food can be dropped into the sorting net box through the discharge tube intermittently to avoid material accumulation; However, it can only reduce the unloading speed. The materials can still only fall into a single position in the sorting box. There will still be a small amount of accumulation. There is still the problem of small particles of materials being transported without being screened out. The sorting is not thorough enough. In addition, This sorting and conveying device uses intermittent opening and closing of baffles to reduce the unloading speed. Materials are easily caught during the movement of the baffles, causing damage to the materials and increasing the amount of scraps, which is not conducive to use.

For this reason, we propose a granular pet food sorting and conveying device to solve the above problems.
