Background

As is well known in the rubber manufacturing field, one of the rubber molding methods is injection vulcanization molding. In the molding method, refined rubber materials are required to be cut into long strips in advance, and then the long strips are injected into a molding die in a heating and extruding manner to implement vulcanization molding. The injection type vulcanization molding mode can reduce the defects and air bubbles on rubber products and improve the yield.

At present, in a rubber production line, the rubber material is cut manually, and the cutting process needs to be performed by using a plurality of specific cutters, which can be common scissors or guillotines and the like, and can also be specially designed for specific products. However, these cutters are operated by manpower, so that the width of the cut strip-shaped rubber material is often different in size, which affects the injection link in the subsequent injection vulcanization molding, and the cutting mode needs a large amount of labor, thereby not only increasing the manufacturing cost, but also affecting the production efficiency.

In order to solve the technical problem, the Chinese patent discloses a rubber strip cutting machine, which has the following publication number: CN202592421U, it includes the multi-disc hobbing cutter, and the hobbing cutter is installed on the hobbing cutter axostylus axostyle, and there is the uide bushing at hobbing cutter axostylus axostyle both ends, and there is the roll rod hobbing cutter below, and the hobbing cutter axostylus axostyle is driven by the gear and the motion direction is opposite with the roll rod. The three-phase motor drives the gear to rotate, so that the shaft lever of the hob cutter rotates rapidly and moves reversely with the rolling rod at the lower part, and the cut rubber block is cut into strips through the hob cutter. The strip cutting machine has the disadvantages that rubber is fed manually all the time in the cutting process, the feeding is easier at the beginning, but when the tail of the rubber is fed, the feeding cannot be continued manually, and the cutter can hurt the hand of a worker, so that another project is often needed to pull the adhesive tape outwards at the discharge hole of the machine, the working efficiency is very low, and the operation is very inconvenient.
