[0002] Rubber and plastic is a general term for the rubber and plastic industries, which are both by-products of petroleum. Rubber and plastic are also divided into two types: natural rubber and plastic and synthetic rubber and plastic. Synthetic rubber and plastic also have pollution emissions and are highly toxic; while the country advocates the use of natural rubber and plastic for processing. Natural rubber and plastic production is zero pollution and zero emission, which just meets the international issue of low-carbon life.

[0003] The "rubber and plastic product cutting device" disclosed in its application number "CN202122689989.X" "comprises a main box body and a motor fixed on the left side of the main box body, the output shaft of the motor passes through the right side of the main box body and is fixedly connected to a reciprocating screw, a reciprocating nut is movably sleeved on the reciprocating screw, a cutting assembly is fixed on the upper side of the reciprocating nut, a guide assembly fixed to the inside of the motor is fixed on the lower side of the cutting assembly, a bidirectional threaded rod rotatably connected to the inside of the motor is provided on the rear side of the reciprocating screw, the left end of the bidirectional threaded rod and the left end of the reciprocating screw both pass through the inner wall of the motor and are connected by a synchronous transmission assembly, a pair of long plates are threadedly connected to the bidirectional threaded rod, the upper ends of the two long plates both pass through the top of the main box body and extend to the upper side of the main box body, abutment assemblies located on the upper side of the main box body are provided on the sides of the two long plates close to each other, and a pressure mechanism is provided on the upper sides of the two long plates." In the utility model, the cutting component can be automatically moved and the cutting operation can be realized through the driving action of the motor. The synchronous transmission effect of the synchronous transmission component is cooperated with the multi-directional abutment and fixation of the pair of long plates on the bidirectional threaded rod with the abutment component and the pressure mechanism, so that the rubber and plastic products can be stably fixed, automatic cutting is realized, and the danger of operation is reduced.

When limiting the position of the flexible rubber and plastic product, the clamping force can easily cause the rubber and plastic product to deform, which will cause the incision to tilt, thereby reducing the cutting quality.
