[0008] According to the above technical solution, a lifting plate 2 is fixedly connected to the top of the side plate, and a pressure roller 1 is rotatably connected to the outer wall of the lifting plate 2 through a bearing. The pressure roller 1 presses the material belt onto the blocking component, thereby limiting the position of the material belt. When the equipment is operating normally, the material belt enters from the bottom of the pressure roller 1 on one side, then passes between the pressure roller 2 and the positioning roller, and is finally discharged from the bottom of the pressure roller 1 on the other side.

[0009] According to the above technical solution, the outer wall of the hollow column one is fixedly connected to a right-angle plate, the outer wall of the right-angle plate is fixedly connected to an extension plate, the end of the extension plate away from the right-angle plate is rotatably connected to an auxiliary component through a bearing, the outer wall of the right-angle plate is fixedly connected to a hollow column two, the inner wall of the hollow column two is fixedly connected to a push rod one, the bottom of the push rod one is fixedly connected to the base, and the push rod one controls the height of the movable mechanism, thereby controlling the positions of the pressure roller two and the positioning roller.

Through the connection between the slide plate and the movable column, the function of controlling the moving direction of the auxiliary component is played. By setting the auxiliary component, when the equipment continues the material belt, as the material belt is pushed out from the movable mechanism, the auxiliary component will also pull the material belt forward, thereby giving the material belt a force to move backward, ensuring that the material belt can be stably extended from the movable mechanism, avoiding curling of the material belt when it is extended from the movable mechanism, and ensuring the stability of the equipment operation.

[0012] According to the above technical solution, one end of the movable column away from the connecting plate one is fixedly connected to a connecting block, the inner wall of the connecting block is fixedly connected to a push rod two, the bottom of the push rod two is fixedly connected to the connecting plate two, and the outer wall of the connecting plate two is fixedly connected to a pressure plate two.

[0016] 1. The present invention sets a movable mechanism, which lowers the height of the second pressure roller and the positioning roller when the equipment continues to connect the material belt, so that the material belt in front of the material belt can move toward the direction of the blocking component, so that the material belt can automatically move backward and dock with the material belt behind, thereby enhancing the automation degree of the equipment and improving the production efficiency of the equipment.

[0017] 2. The present invention sets a movable mechanism.

In this way, when the height of the pressure roller 2 and the positioning roller decreases, the material belt will only move to one side, ensuring that the extended material belt can fit with the next material belt, thereby ensuring the stability of the equipment operation.

[0018] 3. The present invention sets an auxiliary component. When the equipment continues to connect the material belt, as the material belt is pushed out of the movable mechanism, the auxiliary component will also pull the material belt forward, thereby giving the material belt a force to move backward, ensuring that the material belt can be stably extended from the movable mechanism, avoiding the material belt from curling when extending from the movable mechanism, and ensuring the stability of the equipment operation.

[0019] 4. The present invention sets a blocking component, and when the equipment continues to connect the material strip, the front end of the rear side material strip is allowed to rest on the blocking plate, so as to control the position of the material strip and ensure that the connection between the two material strips is located at the bottom of the welding gun each time welding. There is no need to make a secondary adjustment to the position of the welding gun, thereby improving the working efficiency of the equipment. At the same time, after the positioning of the material strip is completed, the material strip will be fixed to ensure the welding effect of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
