[0025] refer to Figure 2 and Figure 3 The moving assembly 51 includes a screw rod 511, a sleeve 512 and a moving block 513. The screw rod 511 is arranged inside the rotating shaft 3, and the left and right ends are respectively rotatably connected to the left and right side surfaces inside the rotating shaft 3. The right end of the screw rod 511 extends out of the rotating shaft 3, passes through the body 1, and is rotatably connected to the body 1. The sleeve 512 is sleeved on the surface of the screw rod 511 and is threadedly connected to the screw rod 511. The position of the sleeve 512 corresponds to the position of the cutter 4. There are two moving blocks 513, which are respectively arranged in the two moving grooves 6 and are slidably connected to the two moving grooves 6. The ends of the two moving blocks 513 that are close to each other are fixedly connected to the sleeve 512, and the ends that are away from each other are fixedly connected to the inner wall of the cutter 4.

[0026] The above solution is adopted: by providing a moving assembly 51 to move the cutter 4 left and right, the cutter 4 is driven to move by the cooperation of the sleeve 512 and the screw rod 511, thereby performing the adjustment function.

[0027] refer to Figure 2 A plurality of adjustment slots 7 are provided on the upper and lower surfaces of the rotating shaft 3 , and the plurality of adjustment slots 7 are connected to the interior of the rotating shaft 3 .

[0028] The above solution is adopted: by opening a plurality of adjustment grooves 7 on the upper and lower surfaces of the rotating shaft 3, which are used to cooperate with the positioning component 52 to position the cutter 4 and serve as a distance reference when adjusting the cutter 4.

[0029] refer to Figure 3 and Figure 4The cam 523 is a substantially parallel plate 524 that is fixed to the upper and lower surfaces of the cam 524 so as to prevent the cam 523 from sliding out of the cam 524. The cam 523 is a substantially parallel plate 524 that is fixed to the upper and lower surfaces of the cam 524 so as to prevent the cam 523 from sliding out of the cam 524.

[0030] The above solution is adopted: by setting a positioning component 52, which is used to cooperate with the adjustment slot 7 to position the cutter 4, so that the cutter 4 will not rotate when the rotating shaft 3 rotates, and cooperate with the adjustment slot 7 to provide a reference for the adjustment distance of the cutter 4.

[0031] refer to Figure 3 The buffer assembly 53 includes a slide rod 531 and a spring 532. There are two slide rods 531, which are respectively arranged on the front and rear sides of the interior of the rotating shaft 3. The left ends of the two slide rods 531 are fixedly connected to the left surface of the interior of the rotating shaft 3, and the right ends pass through the sleeve 512 and the box body 521, and are fixedly connected to the right surface of the interior of the rotating shaft 3. The slide rod 531 is slidably connected to the sleeve 512 and the box body 521. There are two springs 532, which are respectively sleeved on the right end surfaces of the two slide rods 531. The left and right ends of the two springs 532 are respectively fixedly connected to the right surface of the box body 521 and the right surface of the interior of the rotating shaft 3.

[0032] The above solution is adopted: by providing a buffer assembly 53, it is used to position the sleeve 512 and the box body 521 to prevent deviation, and to give the sleeve 512 and the box body 521 a thrust to reduce the shaking during movement.

[0035] The working principle of this utility model:

[0036] When adjusting, by turning the knob 8, the shaft 3 rotates and the screw rod 511 rotates in the shaft 3. When the screw rod 511 rotates, the sleeve 512 and the screw rod 511 connected thereto are driven to move on the surface of the slide rod 531 in the shaft 3, and the spring 532 is squeezed. When the sleeve 512 moves, the two moving blocks 513 move in the moving groove 6. When the moving block 513 moves, the cutter 4 moves on the surface of the shaft 3 to adjust. When the box body 521 moves, the clamping head 523 is squeezed against the inner wall of the adjusting groove 7, so that the clamping head 523 slides into the box body 521 on the surface of the moving rod 522, and the push spring 524 is squeezed and compressed. After the adjusting groove 7 is adjusted to the appropriate position, the clamping head 523 is no longer squeezed, and the push spring 524 will push the clamping head 523 to the outside of the box body 521 and into the corresponding adjusting groove 7, thereby preventing the cutter 4 from rotating.

[0037] To sum up: the strip cutting machine for manufacturing sealing rubber solves the problem that the cutter of the existing strip cutting machine is usually connected to the rotating shaft by bolts or welding, which is not conducive to adjusting the cutter, and thus it is not easy to adjust the cutting width according to the situation during use, resulting in a limited scope of use.
