A feed hopper with screening function

Abstract

The invention relates to the technical field of plastic feed hoppers, and discloses a feed hopper with a screening function, including a discharge hopper, an anti-blocking assembly located in the discharge hopper, a screening box, and a screening assembly located in the screening box; the screening box Located above the discharge hopper, there is an input box on the side above the screening box, and there are criss-crossing bulk rods inside the input box, so that the plastic is dispersed first when it enters the screening box from the input box; the screening assembly includes two stages Screening, the two-stage screening is the first screening assembly and the second screening assembly. When the discharge speed of the plastic needs to be slowed down, the cylinder is pushed to make the fixed rod move downwards as a whole under the action of the guide groove set at the bottom of the fixed rod and the limit rod, so that the arc groove leaves the tail of the push block The position of the linkage ball, and then the linkage ball is extruded outward by the fixed rod, so that the pushing block is stretched out, hindering the discharge of the plastic, and then the speed of the discharge of the plastic can be controlled.

Description

technical field [0001] The invention relates to the technical field of plastic feeding hoppers, in particular to a feeding hopper with a screening function. Background technique [0002] Plastic particles, commonly known as plastic particles, are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. With the rapid development of social economy, the scope of use of plastic particles has become wider and wider. In the production process of plastic pellets, it is necessary to use a large number of feed hoppers. In the production process of plastic pellets, plastic pellets are sometimes doped with a large amount of fine impurities. If these impurities are not removed, it will seriously affect the The quality of the product; if another processing procedure is added in the production process, a lot of manpower and material resources will be wasted.

Problems solved by technology

In the production process of plastic pellets, it is necessary to use a large number of feed hoppers. In the production process of plastic pellets, plastic pellets are sometimes doped with a large amount of fine impurities. If these impurities are not removed, it will seriously affect the The quality of the product; if another processing procedure is added in the production process, a lot of manpower and material resources will be wasted

[0003] Although some feed hoppers currently on the market have the function of screening, most of them only carry out simple coarse screening of plastics. During screening, larger or smaller plastic particles will be screened out, resulting in waste of plastic particles, and in the use of When feeding into the hopper for discharging, due to the certain elasticity of the plastic granules, when the plastic granules pass through the connecting pipe at the bottom of the hopper, the bottom of the hopper is often blocked, which brings great inconvenience to the production of plastic granules. When discharging through the hopper, because some plastic particles are small, when the same type of hopper is used for discharge, the discharge speed is too fast, and it is difficult to control the amount of plastic particles discharged
