Electric control type wood leftover material classifying and screening device

Abstract

The invention discloses an electric control type wood leftover material classifying and screening device, and relates to the technical field of wood processing devices. The electric control type woodleftover material classifying and screening device comprises a support, wherein a box body is rotatably connected onto the support; a rotating motor is installed at the bottom of the support; the output end of the rotating motor drives the box body to rotate around the horizontal axial direction of the box body through a synchronous belt; a feeding bin door is installed on the top side of the boxbody; a discharging bin door is installed on the bottom side of the box body; a vibration motor is installed in the box body; and the box body is connected with a thermal control screen plate in a sealed and sliding mode along the axial horizontal plane of the box body. According to the electric control type wood leftover material classifying and screening device provided by the invention, a controller controls multiple electric heating wires to be powered on and dynamically adjusts the power-on intensity of the electric heating wires under feedback signals of a temperature sensor, and stabletemperature control is formed, so that different temperatures of the electric heating wires are controlled; and at the moment, memory metal sheets wound by the electric heating wires are heated and expanded at different temperatures to form different radius states, so that wood with different particle sizes can be screened, and multi-stage screening can be completed by one thermal control screen plate.

Description

technical field [0001] The invention relates to the technical field of wood processing devices, in particular to an electronically controlled wood scrap grading and screening device. Background technique [0002] In the process of processing wood, a large amount of leftovers are usually produced, and some of the leftovers need to be crushed to form wood particles with small particle sizes when they are used, so that they can be mixed with other materials to make corresponding composite materials. For the utilization effect of particles, wood particles are generally screened according to particle size, so as to further improve their utilization rate. When the existing leftover material screening device is used, it often adopts one-level screening, which not only needs to frequently transport the wood screened by the upper level to the lower-level screening device, resulting in a slow screening speed, but also takes up a lot of multiple screening devices. space.
