Problems solved by technology

However, in the actual operation process, we found that the two sides of the rotary-cut sheet that has been flattened by high temperature are easy to warp. The reason is that the surface temperature of the rotary-cut sheet is very high. Due to the principle of expansion and contraction, the edge of the rotary cutting board will be upturned, which will reduce the aesthetics of the rotary cutting board

Abstract

The invention relates to the technical field of polytetrafluoroethylene production, in particular to a polytetrafluoroethylene rotary cutting board leveling device, which includes a processing table, a feeding roller and a winding roller arranged on the left and right sides of the top surface of the processing table, and the processing table There is a preheating mechanism on the top surface of the processing table and close to the discharge roller, which is used to preheat the PTFE material, and a cooling mechanism is provided on the top surface of the processing table and close to the winding roller, which is used to cool the PTFE Material; the top surface of the processing table is provided with an anti-warping mechanism between the preheating mechanism and the cooling mechanism. The present invention utilizes the upper hot-pressing part and the lower hot-pressing part to jointly press the middle part of the rotary-cut plate, and uses the side-holding plate to press-fit the edge part of the rotary-cutting plate. plate, so it can effectively reduce the edge upturning of the rotary cutting plate.

Description

technical field [0001] The invention relates to the technical field of polytetrafluoroethylene production, in particular to a polytetrafluoroethylene rotary cutting board leveling device. Background technique [0002] PTFE rotary cutting board is made of pure PTFE resin through hydraulic pressure / molding, sintering and rotary cutting. The product has good chemical corrosion resistance, aging resistance, excellent dielectric properties and extremely low friction coefficient, non-adhesive, non-toxic, and can be used for a long time in the range of -196°C to 260°C under no-load conditions. Existing PTFE rotary cutting boards are mainly used as electrical insulation materials and linings, seals and lubricating materials in contact with corrosive media. Sealing material. [0003] According to the traditional processing technology to produce PTFE rotary cut board, the surface flatness of the produced rotary cut board is not good, and the front and back sides of the board are pro...
