Description

Technical Field

[0001] The invention belongs to the technical field of polytetrafluoroethylene processing equipment, and in particular relates to a slice cutting system and method. Background Art

[0002] Polytetrafluoroethylene (F4, PTFE), commonly known as the "King of Plastics," has a series of excellent performance properties: high temperature resistance - long-term use temperature of 200-260 degrees, low temperature resistance - still soft at -100 degrees; corrosion resistance - resistant to strong acids and alkalis and all organic solvents; weather resistance - the best aging life among plastics; high lubricity - has the lowest friction coefficient (004) among plastics; non-stickiness - has the lowest surface tension among solid materials and does not adhere to any substance; non-toxicity - has physiological inertness. Due to the excellent corrosion resistance of polytetrafluoroethylene, it has been widely valued as a structured packing and has achieved good corrosion resistance in applications. After polytetrafluoroethylene is pressed into corrugated sheets by equipment such as bending machines, it needs to be cut by a cutting machine to cut the corrugated sheets into preset lengths, making it easier for operators to transport the corrugated sheets.

[0003] Document CN112318561B discloses a device for producing polytetrafluoroethylene sheets with adjustable cutting length. The device comprises a first cutting table and a second cutting table, with two telescopic mechanisms mounted between the two tables. A polytetrafluoroethylene sheet is placed on the first cutting table, a cutting blade is mounted on the first cutting table, and a drive mechanism is mounted on the first cutting table to cooperate with the cutting blade. Multiple fixed rods are fixed to the second cutting table, with a screw rod rotatably connected between each pair of corresponding fixed rods. A first belt drive mechanism is mounted between the two screw rods, and a second servo motor is fixed to one of the fixed rods. The device controls the length of the polytetrafluoroethylene sheet each time it moves from the first cutting table to the second cutting table by adjusting the spacing between the first cutting table and the second cutting table. A movable clamp cooperates with the adjustment mechanism to secure polytetrafluoroethylene sheets of varying thicknesses, thereby smoothly pulling the sheets.

[0004] However, this device has the following disadvantages when used to cut polytetrafluoroethylene corrugated plates: first, adjusting the cutting length requires adjusting the distance between the two cutting tables, which has low accuracy and is time-consuming and labor-intensive; second, pulling the corrugated plate requires the clamping and pulling of the clamping plate and the adjustment mechanism, and the pressure foot area is too large, which affects the shape of the corrugated plate.
