Feeding device for automatic weighing and sorting machine

Abstract

The invention discloses a feeding device for an automatic weighing and sorting machine. The feeding device comprises an outer barrel and a spiral blocking piece, wherein the outer barrel is a cylinderwith an open upper end and an enclosed lower end; the outer center of the lower end of the outer barrel is provided with a barrel shaft; the barrel shaft is connected with a power device; the spiralblocking piece is in a spiral shape and placed in the outer barrel; and the spiral blocking piece comprises a lower end part and an upper end part, and a slideway is formed between the lower end partand the upper end part. The feeding device is characterized in that the part, located in the outer barrel, of the slideway is invariable in outer diameter and gradually decreasing in inner diameter, and the narrowest part of the slideway just allows sorted articles to pass through one by one; the part, located out of the outer barrel, of the slideway goes beyond the circumferential boundary of theouter barrel; and a conveyor belt is arranged below and connected with the upper end part. The feeding device of the invention can achieve the effect that piled-up products dumped by workers into theouter barrel can be arranged on the conveyor belt one by one, so the feeding device has the advantages of high degree of automation and high efficiency.

Description

technical field [0001] The invention relates to the field of automatic weighing and sorting equipment for products, in particular to a feeding device for a weighing and sorting machine. Background technique [0002] Automatic weighing and sorting machine is a kind of equipment that can automatically classify products according to the quality of products. It is widely used in the field of classification of agricultural products and aquatic products, which not only saves labor to a great extent, but also greatly improves the accuracy of classification. At present, there are two main types used in our country, one is to weigh and classify through the principle of leverage, the other is to weigh through the weighing module and then process information, and finally let the actuator change the running track of the product, so that achieve the purpose of classification. The latter is wider in terms of product types. However, the latter weighing and sorting equipment must meet a ...

AI Technical Summary

Problems solved by technology

However, the latter weighing and sorting equipment must meet a requirement that only one product on the conveyor belt must pass through the weighing module at a certain point in time.

Therefore, in actual use, it is often necessary to manually place the products on the conveyor belt one by one, resulting in low automation level and efficiency of this type of machine.
