[0002] The rubber strip angle cutter is a device specially used for cutting rubber strips. It plays an important role in the processing and production of rubber strips. The rubber strip angle cutter can cut the rubber strips quickly and accurately, thereby greatly improving the production efficiency. Compared with the traditional manual cutting method, the angle cutter can greatly reduce the operation time and increase the cutting speed, thereby meeting the needs of large-scale production. The existing device has no restrictions on the plate. Each time the angle is cut, the size of the angle needs to be measured, and the plate needs to be held for cutting, which is time-consuming and labor-intensive, and the work efficiency is relatively low.

[0003] For example, the publication number CN219924680U disclosed a corner shearing machine on October 31, 2023, including a corner shearing machine body, a stamping groove is provided on the top of the corner shearing machine body, a screw groove is provided on the top of the corner shearing machine body, a motor is fixedly connected to one side of the corner shearing machine body, a screw is fixedly connected to the output end of the motor, and a ball nut is provided on the outer surface of the screw.

The heat sealing strip is easy and fast to move, and there is no need to manually load the heat sealing strip. The heat sealing strip cutting is easy and fast.

[0017] The rotating shaft on the movable seat is driven to rotate by the first motor, so that the pressure roller on the rotating shaft squeezes and moves the heat sealing strip, thereby realizing the automatic feeding of the heat sealing strip, and the height of the movable seat is adjusted by the cooperation of the adjusting bolt, the fixing bolt and the first spring, and then the pressure roller on the movable seat is adjusted, thereby ensuring that the heat sealing strips of different thicknesses can be moved;

[0018] The limiting strips arranged between the moving seats realize the stable movement of the heat sealing strips, and the two-way screw rods are rotated to realize the relative displacement movement of the two limiting strips, thereby adjusting the distance between the two limiting strips, thereby realizing the limiting and guiding work of the heat sealing strips of different widths;

[0019] The convenient shearing of the heat sealing strip is achieved through the cooperation of the telescopic rod, the movable plate, the bottom plate, the shearing lower plate and the shearing upper plate, and the stable shearing of the heat sealing strip is achieved through the cooperation of the second spring and the third spring, thereby preventing the shearing upper plate and the shearing lower plate from being damaged due to rigid contact;
