Description

Technical Field

[0002] Plastic middle board (also called hollow spacer board, Wantong board, double wall board, corrugated board) adopts modern chemical HDPE and HDPP materials. It is a new material with light weight (hollow structure), non-toxic, pollution-free, waterproof, shockproof, anti-aging, corrosion-resistant and rich colors. Compared with cardboard structural products, hollow board has the advantages of moisture-proof, corrosion-resistant and lighter to replace cardboard. Compared with injection molding products, hollow board has the advantages of shockproof, flexible design structure, and no need to open injection molds. At the same time, the board can flexibly add anti-static and conductive masterbatch through the control of raw materials to produce plastic hollow board with conductive and anti-static functions.

[0003] The plastic hollow board still retains a relatively high temperature after extrusion, so it is necessary to use cooling equipment to quickly cool and mold the plastic hollow board. However, the cooling space in the existing cooling and molding equipment cannot be adjusted to the width of the plastic hollow board, resulting in a large amount of cold air still needing to be injected into the cooling chamber when cooling the narrower plastic hollow board, resulting in a large amount of cold air waste. In order to solve the above problem, an adjustable plastic hollow board production equipment is proposed in the present application. Utility Model Content
