Cutting machine for forming external wall heat-insulating plates

Abstract

The invention belongs to the technical field of plate machining equipment, in particular to a cutting machine for forming external wall heat-insulating plates. The cutting machine comprises a charging conveyor and a discharging conveyor, wherein a centering device, a main cutting device and a fixed-length cutting device are sequentially arranged in a plate flowing direction of the charging conveyor; the centering device is used for adjusting positions of blanks to make the blanks align with the center of a back cutting device; the main cutting device is used for performing peeled cutting and layered cutting on the blanks; the fixed-length cutting device is used for cutting the blanks subjected to peeled cutting and layered cutting according to fixed length; and the discharging conveyor is positioned behind the fixed-length cutting device. The cutting machine is rational in structural design; the whole process of cutting the blanks and final plates are divided into three steps, namely centering, peeled cutting and layered cutting, and fixed-length cutting, so that division of labor of devices is clear, and the devices are matched closely; and the cutting machine has high automaticity, and good cutting and forming effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of plate processing equipment, and in particular relates to a forming and cutting machine for external wall insulation boards. Background technique [0002] The exterior wall insulation board is a board installed in the exterior wall of a building to play a role in heat insulation. For a long time, my country's external wall insulation boards are mostly made of non-flame-retardant materials such as PE, and the cutting and forming of these boards generally adopts the method of electric heating fusion cutting. However, as the Ministry of Public Security has increased the fire protection level requirements for external wall insulation materials, single flame-retardant or composite flame-retardant panels have begun to appear on the market. Due to its own flame retardant properties, this material cannot be cut by electrothermal fusion cutting, so band saw or wire saw is often used for processing. However, due t...

Problems solved by technology

However, due to the limitation of moving parts, this processing method is usually a single saw, and at most three saws. The board needs to be cut repeatedly, so the production efficiency is low and the labor intensity of the workers is high. Generally, three to four sets of production lines are required.

What's more serious is that when producing high flame-retardant PE composite panels, due to the heavy mold material (the blank after composite molding, the size is 1250mm*630mm*6150mm, and the weight is 200-300Kg), manual handling and centering operations often Destroy the mold material, resulting in waste of raw materials
