DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a cutting device for foam glue production, comprising a frame 1, a one-way screw 2 is rotated at a position near the top in the middle of the frame 1, a servo motor 5 for driving the one-way screw 2 to rotate is installed on one side of the frame 1, a guide rod 10 is fixed in the frame 1 just above the one-way screw 2, a moving block 3 is installed outside the one-way screw 2 and the guide rod 10, and the moving block 3 and the one-way screw 2 are threadedly connected, and the moving block 3 and the guide rod 10 are slidably connected, a knife holder 4 is arranged above the moving block 3, a cylinder 15 for driving the knife holder 4 to move up and down is installed at the top of the moving block 3, a knife body 12 is installed on the knife holder 4, a guide rod 21 is fixed inside the frame 1, and a guide hole 17 is opened on the guide rod 21, and a symmetrical guide plate 8 is arranged outside the guide hole 17. The foam glue passes through the device between the two guide plates 8 below the knife body 12, and is guided by the two guide plates 8. Then, the output shaft of the servo motor 5 is used to drive the one-way screw 2 to rotate in forward and reverse directions, so that the moving block 3 moves smoothly, and the knife body 12 is moved to accurately correspond to the foam glue to be cut. Then, the cylinder 15 is started, and the cylinder 15 contracts to move the knife holder 4 downward, and the foam glue is cut by the knife body 12.

[0022] See also Figure 1-4 A bidirectional screw 7 is rotated at one end of the frame 1 and directly below the guide rod 21. A servo motor 11 driving the bidirectional screw 7 is installed on one side of the frame 1. A screw hole 16 for the servo motor 11 to pass through is opened transversely in the guide plate 8. Since the thread patterns on both sides of the bidirectional screw 7 are opposite, the bidirectional screw 7 rotates during the rotation of the output shaft of the servo motor 11, and the two guide plates 8 move in relative directions, so that they can be reasonably adjusted according to the width of the cut foam glue.

[0023] See also Figure 1-3 A roller rod 1 6 is fixed at one end of the frame 1, and a roller rod 2 13 is fixed at one end of the frame 1 away from the roller rod 1 6. The roller rod 2 13 and the screw hole 16 play a bearing role for the foam glue.

[0024] See also Figure 3-4 A clamping plate 14 is fixed at the bottom of one end of the two guide plates 8 close to each other, a clamping plate 20 is arranged on the clamping plate 14, and a cylinder 29 is installed on the guide plate 8 to drive the clamping plate 20 to move up and down. In addition, a guide groove 18 is opened horizontally at a position close to one end of the guide plate 8 and above the clamping plate 14, and a protrusion is fixed at one end of the clamping plate 20, and the clamping plate 20 is arranged in a "T" shape when viewed from above. And the protrusion extends into the inside of the guide groove 18. The guide groove 18 guides the second splint 20. During the up and down movement of the second splint 20, the cooperation of the guide groove 18 can ensure that the second splint 20 moves up and down smoothly, and the second splint 20 and the first splint 14 are always kept accurately corresponding. In subsequent use, the cylinder 2 19 is started, and the cylinder 2 19 is expanded to move the second splint 20 up and down. Since both sides of the foam glue are located between the second splint 20 and the first splint 14, the second splint 20 and the first splint 14 are used to clamp the foam glue to be cut. This not only makes it convenient for the knife body 12 to cut the foam glue, but also makes it convenient to quickly grasp the end of the foam glue later.

[0025] A control panel 9 is installed above one end of the frame 1, and the output ends of the control panel 9 are electrically connected to the input ends of the servo motor 1 5, the servo motor 2 11, the cylinder 1 15, and the cylinder 2 19; the models of the servo motor 1 5 and the servo motor 2 11 can both be QS-750W; the models of the cylinder 1 15 and the cylinder 2 19 can both be SU32X75.

[0026] Working principle: The foam glue passes through the frame 1 around the roller rod 2 13 and the guide rod 2 21, and the servo motor 2 11 is started. The output end of the servo motor 2 11 drives the bidirectional screw 7 to rotate to reasonably adjust the distance between the two guide plates 8 according to the width of the foam glue. At this time, both sides of the foam glue are located between the clamping plate 1 14 and the clamping plate 20. When it is necessary to cut the foam glue, the cylinder 2 19 is started. The cylinder 2 19 squeezes the clamping plate 20 downwards, and the clamping plate 14 and the clamping plate 20 clamp the foam glue and fix it. The servo motor 2 is started. Machine 1 5 adjusts the position of the knife body 12 reasonably as needed to ensure that the knife body 12 and the foam glue correspond, starts cylinder 15, and the knife holder 4 moves downward. At this time, the foam glue is cut by the knife body 12, and then the cylinder 2 19 is started again. The cylinder 2 19 shrinks the splint 20 and moves it upward. The staff will grasp and pull the end of the foam glue clamped between the splint 20 and the splint 1 14. After the foam glue is rolled up by the winding drum, it will continue to be cut by the knife body 12 when it needs to be cut again.
