The guide cutting device 6 includes a support plate 61, a motor 62 fixedly connected to the top of the support plate 61, a rotating shaft 63 fixedly connected to the output shaft of the motor 62, a drive gear 64 fixedly connected to the front side of the rotating shaft 63, a rotating rod 65 fixedly connected to the front side of the drive gear 64, a fixed plate 66 rotatably connected to the front side of the rotating rod 65, and the bottom of the fixed plate 66 fixedly connected to the extension platform 5. At the top, a rotating rod 67 is rotatably connected to the back side of the fixed plate 66. A guide belt 68 is driven to the circumferential surface of the rotating rod 65. The inner wall of the guide belt 68 is driven to the circumferential surface of the rotating rod 67. A rotating shaft 69 is rotatably connected to the back side of the fixed plate 66. A driven gear 610 is fixedly connected to the back side of the rotating shaft 69. A belt 611 is driven to the circumferential surface of the rotating shaft 63. A connecting post 612 is driven to the inner wall of the belt 611. A connecting plate 613 is rotatably connected to the back side of the connecting post 612. The front side of the connecting plate 613 is fixedly connected to the back side of the extension platform 5. A half gear 614 is fixedly connected to the front side of the connecting post 612. A sliding groove 615 is provided at the top of the extension platform 5. A rack 616 is slidably connected to the inner wall of extension platform 5. A connecting rod 617 is fixedly connected to the top of rack 616, and a cutting blade 618 is fixedly connected to the bottom of connecting rod 617. The belt 611 drives the connecting column 612 to rotate, and the half gear 614 indirectly pushes rack 616 to move. The cutting blade 618 cuts the rubber strip. A cutting plate 619 is fixedly connected to the top of extension platform 5, and a force plate 620 is fixedly connected to the side of rack 616. A return spring 621 is fixedly connected to the bottom of force plate 620. The end of return spring 621 away from force plate 620 is fixedly connected to the top of extension platform 5. The function of return spring 621 is to cut the rubber strip.

The function of the circumferential surface of the driving gear 64 meshing with the circumferential surface of the driven gear 610 is to drive the driven gear 610 to rotate when the driving gear 64 rotates.

[0027] like Figure 1 - Figure 2 , Figure 4 - Figure 5 As shown, the adhesive strip cutting machine of this utility model is similar to existing adhesive strip cutting machines, such as the adhesive strip guiding device of an adhesive strip extruder disclosed in CN209440760U. The main improvement of this utility model is that the rotating shaft 63 is driven by the motor 62 to rotate, thereby driving the drive gear 64 to rotate, which in turn drives the guide belt 68 to rotate. When the drive gear 64 rotates, it drives the driven gear 610 to rotate in the opposite direction, so that the two guide belts 68 move relative to each other, thus moving the adhesive strip forward. When the rotating shaft 63 rotates, it drives the belt 611 to rotate. When the belt 611 rotates, it drives the connecting column 612 to drive the half gear 614 to rotate, so that the half gear 614 can push the rack 616 to move downward. Then, the rack 616 drives the cutting blade 618 to move downward through the connecting rod 617, thus achieving the cutting of the adhesive strip. Through the action of the half gear 614 and the return spring 621, the rack 616 can indirectly drive the cutting blade 618 to move downward to cut the adhesive strip.

A collection box 79 is fixedly connected to the front side of the extension platform 5. A limit rod 710 is fixedly connected to the front side of the connecting plate 613. The front side of the limit rod 710 passes through... On the front side of the threaded sleeve 75, the circumferential surface of the limiting rod 710 is slidably connected to the inner wall of the threaded sleeve 75. The push plate 78 is used to push the rubber strips cut from the extension table 5 into the collection box 79.

The two collection boxes 79 are symmetrical about each other along the vertical central axis of the extension table 5 to better collect the rubber strips.

[0029] like Figure 3 , Figure 6 As shown, the rotation of the connecting column 612 can drive the first sprocket 71 to rotate. When the first sprocket 71 rotates, it can drive the second sprocket 73 to rotate through the chain 72. When the second sprocket 73 rotates, it will drive the threaded rod 74 to rotate on the connecting plate 613. When the threaded rod 74 rotates, it will drive the threaded sleeve 75 to move back and forth along the limit rod 710. When the threaded sleeve 75 moves back and forth, it will drive the push plate 78 to move back and forth through the fixed rod 76. This will push the cut rubber strips on the extension table 5 into the collection boxes 79 on both sides of the extension table 5, thus collecting the cut rubber strips.
