A device for accurately proportioning and feeding straw board surface materials

Abstract

The invention relates to the technical field of straw board production, in particular to a feeding device for accurately proportioning the surface material of straw boards, comprising a wooden surface bunker, a straw shaving bin, and a scraper conveyor. The wooden surface bunker and the straw shaving bin are symmetrical. It is set that the bottom ends of the wooden surface silo and the straw shaving silo are connected with a tapered discharge pipe, and an auger conveyor is fixed below the wooden surface silo and the straw shavings silo, and the conical discharge pipe The feed pipe is connected with the feed port of the auger conveyor, the discharge port of the auger conveyor is arranged directly above the feed end of the scraper conveyor, and a first motor is arranged outside the feed port of the auger conveyor, A frequency converter is fixed on the outside of the first motor; the present invention can not only realize the controllability of the material ratio of the surface layer of the straw board through the frequency converter, but also ensure that the transportation speed of the auger conveyor is relatively fast. The accuracy of raw materials ensures the quality of the straw board produced.

Description

Precise proportioning feeding device for straw board surface material technical field The present invention relates to the technical field of straw board production, be specifically related to a kind of straw board surface layer material accurate proportioning charging device set. Background technique Traditional straw particle board surface material is made up of wood fine material and straw wood shavings, generally straw shavings and wood fine material The processing is divided into independent sections, which are collected into the same silo after drying, and it is difficult to achieve wood and straw materials according to The ratio of process requirements often results in the instability of the quality of the straw board. In view of the fact that the existing straw board cannot be added according to the process requirements The quality problems caused by the material, most companies use the assembly with frequency conversion control of the discharge screw, by ch...
