Description

Technical Field

[0001] The utility model relates to the field of hollow plate fixing fixtures, in particular to a fixture used for cutting plastic hollow plates. Background Art

[0002] Plastic hollow 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 structure design, 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. The surface resistivity of anti-static board can be controlled between 103 and 1011.

[0003] At present, most of the fixing fixtures used for cutting plate materials adopt a four-point fixing method. Since the four-point fixing method has a large pressure at the clamping position of the fixture, when cutting the plastic hollow plate, it is easy to cause the clamping position of the plastic hollow plate to deform, thereby damaging the plastic hollow plate. Therefore, the market urgently needs to develop a fixture for cutting plastic hollow plates to help people solve the existing problems. Utility Model Content
