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 and particularly relates to a polytetrafluoroethylene rotary cut plate leveling device. The polytetrafluoroethylene rotary cut plate leveling device comprises a machining table, a discharging roller and a winding roller, wherein the discharging roller and the winding roller are arranged on the left side and the right side of the top surface of the machining table; a preheating mechanism is arranged at a position, close to the discharging roller, of the top surface of the machining table and is used for preheating a polytetrafluoroethylene material; a cooling mechanism is arranged at a position, close to the winding roller, of the top surface of the machining table and is used for cooling the polytetrafluoroethylene material; and an anti-warping mechanism is arranged on the top surface of the machining table and is located between the preheating mechanism and the cooling mechanism. According to the polytetrafluoroethylene rotary cutting plate leveling device, an upper hot-pressing part and a lower hot-pressing part are used for jointly pressing a middle part of a rotary cut plate; an edge pressing plate is used for pressing the edge part of the rotary cut plate; the temperature of the edge pressing plate is obviously lower than that of an upper heating plate / a lower heating plate, so that the phenomenon that the edge of the rotary cut plate warps upwards can be effectively reduced.

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...
