PVC free foaming plate production equipment

Abstract

The invention relates to the technical field of plastic processing, and discloses PVC free foaming plate production equipment. The equipment comprises a machine body, wherein a calendaring mechanism is fixedly connected to the middle of the upper surface of the machine body; a material conveying cavity is fixedly connected to the left side of the upper surface of the machine body; a feed hopper isfixedly connected to the top of the material conveying cavity; and a servo motor is fixedly connected to the portion, on the left side of the feed hopper, at the top of the machine body. According tothe PVC free foaming plate production equipment, the sides, opposite to each other, of an upper rotating roller and a lower rotating roller are each uniformly and fixedly connected with eight rotating rods; when foaming material moves, the foaming material moves in the same direction with the rotating rods in contact with the foaming material correspondingly, so that the sticking situation amongthe rotating rods and the foaming material is avoided, and the smoothness of a foaming plate produced by the PVC free foaming plate production equipment is improved; meanwhile, the original sliding friction contact mode is replaced by the sliding connection, so that the heating uniformity of the foaming material is improved; and an adjustable smoothing plate is parallel to the tangent plane at thetop of the corresponding upper rotating roller, so that the flattening effect of the foaming plate is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to production equipment for PVC free foam boards. Background technique [0002] PVC free foam board is a kind of PVC foam board. According to the production process, PVC foam board can be divided into PVC crust foam board and PVC free foam board. PVC foam board is also called Chevron board and Andy board. The board, whose chemical composition is polyvinyl chloride, has stable chemical properties, acid and alkali resistance, corrosion resistance, moisture and mildew resistance, heat insulation, sound insulation and sound absorption, flame retardant and self-extinguishing, smooth surface, mothproof, light weight, non-absorbent, polychloride Ethylene is a polymer formed by polymerization of vinyl chloride monomer in peroxides, azo compounds and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride ho...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a PVC free foaming board production equipment, which improves the heating uniformity of the foaming material, and uses an adjustable smoothing plate to be parallel to the cutting surface on the top of the corresponding upper roller, improving the straightness of the foaming board. The advantages of the effect solve the problem that the three rollers on the existing PVC free foaming board production equipment are generally installed on the opposite side of the contact with the slab of the corresponding PVC free foaming board. Sliding friction occurs on the outer surface of the PVC free foam board slab, which is likely to cause wear of the PVC free foam board slab. The temperature of the confluent core of the foam board slab is high, which causes the problem that the middle of the slab is thick and the sides are thin
