Hot-pressing device for PVC flame-retardant plastic-wood composite material

Abstract

The invention discloses a hot-pressing device for a PVC flame-retardant plastic-wood composite material, and relates to the technical field of material processing equipment. The hot-pressing device comprises a workbench, wherein the workbench is sequentially provided with a weighing table, a hot pressing groove, a hot pressing mechanism, a compression roller mechanism, a conveying mechanism and a cooling mechanism in the length direction of the workbench, the hot pressing groove is formed in the weighing table, electric heating tubes are embedded in the peripheral side wall of the hot pressing groove, the side wall, far away from the weighing table, of the hot pressing groove is provided with a material passing opening, and the cooling mechanism comprises a fan and a smoke removing box. According to the device, the weighing table, the hot pressing groove, the hot pressing mechanism, the pressing roller mechanism and the cooling mechanism are arranged, particles are weighed through the weighing table, preheating and leveling are performed in the hot pressing groove, and the particles are pressed into a plate with a certain thickness through the hot pressing mechanism, and then flattening and compacting are further carried out through the compression roller mechanism, so that the problem that the quality of the plate after hot pressing of an existing hot press is not too close is solved, the tail gas is reused, pollution is avoided, the operation is simple, and the device is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of material processing equipment, and in particular relates to a PVC flame-retardant plastic-wood composite material hot-pressing device. Background technique [0002] PVC flame-retardant plastic-wood composite material is a composite material made of wood, PVC plastic and high-content flame-retardant auxiliary raw materials. Due to the good environmental performance and quality improvement of flame-retardant plastic-wood composite materials, people's acceptance is gradually increasing , the output is increasing year by year. Particle hot pressing is a process in the processing of flame-retardant wood-plastic composite materials, and it is also a key step that directly affects the quality of wood-plastic composite materials. [0003] Existing hot-pressing equipment has certain disadvantages in use. The hot-pressing effect is poor, so that the quality of the board after hot-pressing is not satisfactory, and ...

AI Technical Summary

Problems solved by technology

[0003] The existing hot-pressing equipment has certain disadvantages in use. The hot-pressing effect is poor, so that the quality of the board after hot-pressing is not satisfactory, and a large amount of smoke is generated during the production process, which seriously endangers the physical and mental health of the operating staff.
