[0024] The lower ends of the two support plates 2 are slidably connected to sliders 6, and a moving roller 5 is rotatably connected between the two sliders 6, which can cooperate with the cutting roller 4 to extrude and fix the adhesive foam. The surface of the base 1 is slidably connected to two moving blocks 8, and the surfaces of the two moving blocks 8 are rotatably connected to connecting rods 9. Both ends of the moving roller 5 are rotatably connected to a connecting frame 10, and the ends of the two connecting rods 9 away from the moving blocks 8 are rotatably connected to the surface of the connecting frame 10. A bidirectional threaded rod 7 is rotatably connected between the two support plates 2, and the bidirectional threaded rod 7 passes through the surfaces of the two moving blocks 8 and is connected to the internal threads of the two moving blocks 8. The internal threads of the two moving blocks 8 match the threads at both ends of the bidirectional threaded rod 7 respectively, so that when the staff rotates the bidirectional threaded rod 7, they can smoothly drive the two moving blocks 8 to move relative to or away from each other on the base 1.

[0025] The surface of the cutting roller 4 is provided with equidistantly arranged tool holders 11 , which are semicircular in shape. The surface of the tool holder 11 is fixedly connected to the surface of the cutting knife 12 , providing an installation space for the cutting knife 12 to be installed on the cutting roller 4 .

[0026] One end of the tool holder seat 11 is slidably connected to a connecting block 17 with a trapezoidal cross-section. A ball 18 is inlaid inside the tool holder seat 11. The surface of the ball 18 is in contact with the surface of the connecting block 17, which reduces the friction of the connecting block 17 sliding in the tool holder seat 11 and improves the smoothness of the connecting block 17 when sliding. The inside of the tool holder seat 11 is slidably connected to a force rod 19 protruding from the surface of the tool holder seat 11. One end of the force rod 19 is located inside the tool holder seat 11 and corresponds to the inclined surface of the connecting block 17.

[0027] A connecting groove 20 is provided at the other end of the tool holder seat 11, and a baffle 22 is slidably connected to the inner wall of the connecting groove 20. A first spring 21 is fixedly connected to the surface of the baffle 22. The end of the first spring 21 away from the baffle 22 is fixedly connected to the inner wall of the connecting groove 20 for resetting the baffle 22. The surface of the force-bearing rod 19 is also movably sleeved with the first spring 21. The two ends of the first spring 21 are respectively fixedly connected to the surface of the force-bearing rod 19 and the interior of the tool holder seat 11.

[0028] A slide groove 15 is provided on the surface of the cutting roller 4, and a limiting block 16 is fixedly connected to the surface of the tool holder 11. The surface of the limiting block 16 and the inner wall of the slide groove 15 slide with each other to guide the sliding of the tool holder 11 on the cutting roller 4, thereby avoiding the deviation of the movement of the tool holder 11 and the cutting knife 12 on the cutting roller 4, ensuring that the cutting knife 12 will not be deflected, and ensuring the cutting quality of the adhesive-backed foam.

[0029] The inner wall of the slide groove 15 is fixedly connected with a rubber pad 14, and the surface of the rubber pad 14 contacts the surface of the limiting block 16. Therefore, the setting of the rubber pad 14 can increase the friction between the limiting block 16 and the slide groove 15, thereby avoiding the random movement of the tool holder 11 on the cutting roller 4 and ensuring the stability of the device during use.

[0030] Both sides of the limiting block 16 are slidably connected with an extrusion rod 24, and the opposite ends of the two extrusion rods 24 are tapered. Therefore, the tapered setting of the extrusion rods 24 can increase the extrusion force of the extrusion rods 24 on the rubber pad 14, thereby improving the stability of the position of the limiting block 16 in the slide groove 15, avoiding the random movement of the tool holder 11 and the cutting knife 12, and further ensuring the stability of the device during use.

[0031] The surface of the cutting roller 4 is provided with a scale 13 , so that the staff can accurately understand the position of the cutting knife 12 through the setting of the scale 13 , which facilitates the staff to adjust the position of the cutting knife 12 .

[0032] The opposite ends of the two extrusion rods 24 are fixedly connected to a first movable block 26 with a trapezoidal cross-section. The surface of the first movable block 26 is slidably connected to the inside of the limiting block 16. The surfaces of the two extrusion rods 24 are movably sleeved with a second spring 25. The two ends of the second spring 25 are respectively fixedly connected to the inside and outside of the limiting block 16 and the surface of the extrusion rod 24 to reset the extrusion rod 24.

[0033] The internal sliding connection of the limiting block 16 is connected to a pull rod 23 protruding from the surface of the limiting block 16. One end of the pull rod 23 located inside the limiting block 16 is fixedly connected to a second movable block 27. The cross-section of the second movable block 27 is also trapezoidal. The two inclined surfaces of the second movable block 27 are respectively slidably connected to the inclined surfaces of the two first movable blocks 26.

[0034] When cutting the adhesive foam, after the adhesive foam passes through the upper and lower squeezing rollers, the staff can rotate the two-way threaded rod 7 to drive the two moving blocks 8 to move in opposite directions, thereby driving the two connecting rods 9 to gradually become horizontal, and then driving the connecting frame 10 to descend, thereby driving the moving roller 5 to descend, and then the staff can pass the adhesive foam between the two moving rollers 5 and the cutting roller 4, and then rotate the two-way threaded rod 7 in the opposite direction to squeeze the adhesive foam between the cutting roller 4 and the moving roller 5, and then make the winding roller rewind the adhesive foam, and then start the motor 3 , drives the cutting roller 4 to rotate, and then drives the cutting knife 12 to rotate to cut the adhesive foam. Since the adhesive foam is squeezed between the cutting roller 4 and the moving roller 5, the cutting knife 12 can still cut the adhesive foam when the tail end of the adhesive foam passes through the cutting roller 4 and the moving roller 5, thereby avoiding the situation where the adhesive foam is no longer taut after the tail end of the adhesive foam loses tension, making it impossible for the cutting knife to cut the adhesive foam into strips, avoiding the situation where manual subsequent processing of the adhesive foam is required, improving the use effect of the device, and worthy of promotion.

[0035] When the number and spacing of the cutting knives 12 on the cutting roller 4 need to be adjusted, the staff can pull the pull rod 23 to make the pull rod 23 pull the two first movable blocks 26 to move relative to each other in the limiting block 16, thereby driving the two squeezing rods 24 to move relative to each other, stretching the second spring 25 so that the conical surface of the squeezing rod 24 no longer squeezes the rubber pad 14, reducing the resistance of the limiting block 16 to slide in the slide groove 15, and then pushing the knife holder 11 to move on the cutting roller 4 to change the position of the knife holder 11 and the cutting knife 12. At the same time, when it is necessary to increase the cutting knife 12, first the two knife holders 11 are placed end to end relative to each other, and then the knife holder 11 is made to slide on the cutting roller 4, so that the conical surface of the cutting roller 4 is subjected to force The rod 19 pushes, so that the force-bearing rod 19 gradually retracts into the tool holder seat 11, and compresses the first spring 21 on the force-bearing rod 19. At the same time, the retraction of the force-bearing rod 19 pushes the connecting block 17, so that the connecting block 17 gradually inserts into the connecting groove 20, and pushes the baffle 22, so that the first spring 21 is compressed, so that the connecting block 17 is inserted into the connecting groove 20 of the other tool holder seat 11, thereby completing the connection between the two tool holder seats 11, thereby completing the addition of the cutting knife 12, so that the staff only needs to connect the two tool holder seats 11 end to end, and then push the tool holder seat 11 to slide on the cutting roller 4 to complete the addition of the cutting knife 12, thereby facilitating the staff to add and remove the cutting knife 12, and improving the convenience of using the device.

[0036] Working principle: When cutting the adhesive foam, after the adhesive foam passes through the upper and lower squeezing rollers, the staff can rotate the two-way threaded rod 7 to drive the two moving blocks 8 to move in opposite directions, thereby driving the two connecting rods 9 to gradually tend to the horizontal, and then drive the connecting frame 10 to descend, thereby driving the moving roller 5 to descend, and then the staff can pass the adhesive foam between the two moving rollers 5 and the cutting roller 4, and then rotate the two-way threaded rod 7 in the opposite direction to squeeze the adhesive foam between the cutting roller 4 and the moving roller 5, and then make the winding roller face the opposite direction. The adhesive foam is rolled up, and then the motor 3 is started to drive the cutting roller 4 to rotate, thereby driving the cutting knife 12 to rotate and cut the adhesive foam. Since the adhesive foam is squeezed between the cutting roller 4 and the moving roller 5, the cutting knife 12 can still cut the adhesive foam when the tail end of the adhesive foam passes through the cutting roller 4 and the moving roller 5, thereby avoiding the situation where the adhesive foam is no longer taut after the tail end of the adhesive foam loses tension, making it impossible for the cutting knife to cut the adhesive foam into strips.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
