[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 2 to 7 As shown, this embodiment provides a polyurethane pad cutting machine, which includes a workbench 1. In this embodiment, several suction holes 11 are provided on the workbench 1. An air pump 9 is fixedly mounted on one side of the workbench 1 and connected to the suction holes 11. The air pump 9 is used to secure the material to be cut to the workbench 1 using compressed air. A cutting element 5 is provided on the workbench 1 for cutting the material. A first control structure is provided on the workbench 1 to control the movement of the cutting element 5 along the X-axis. A second control structure is provided on the first control structure to control the movement of the cutting element 5 along the Y-axis. A third control structure is provided on the second control structure to control the movement of the cutting element 5 along the Z-axis. A cleaning roller 6 is provided on the workbench 1. A fourth control structure is provided on the first control structure to control the movement of the cleaning roller 6 along the X-axis. A fifth control structure is provided on the fourth control structure to control the rotation of the cleaning roller 6. In this embodiment, a cleaning layer can be provided on the outer wall of the cleaning roller 6. This cleaning layer is made of a plush material. Because the plush material adheres more closely to the workbench 1, it improves the cleaning effect of the workbench 1. The cutting member used in this embodiment can be a rotary cutter for cutting.

[0030] The first control structure in this embodiment includes a first control motor 31. The first sliding rail 21 and the second sliding rail 22 are fixedly arranged on both sides of the workbench 1 to ensure that the first mounting frame 3 will not be displaced during movement. The first mounting frame 3 is arranged on the workbench 1. The first mounting frame 3 is of a "冂" - shaped structure to facilitate the Y - axis movement of the cutting member 5. The first mounting frame 3 is slidably connected to the first sliding rail 21 and the second sliding rail 22 respectively. The first sliding rack 211 is fixedly arranged on one side of the first sliding rail 21. The first transmission gear 311 is rotatably arranged on the first mounting frame 3. The first transmission gear 311 meshes with the first sliding rack 211. The first control motor 31 is fixedly connected to the first mounting frame 3, and the output shaft of the first control motor 31 is fixedly connected to the first transmission gear 311. In this embodiment, the forward and reverse rotation of the first control motor 31 is used to realize the X - axis movement of the cutting member 5, which is convenient for the cutting member 5 to cut the cutting material.

[0031] In this embodiment, the lengths of the first sliding rail 21 and the second sliding rail 22 are greater than the length of the workbench 1 to facilitate moving the cutting member 5 away from the cleaning roller 6 and facilitate the cleaning work of the cleaning roller 6. The air extraction chamber 12 is arranged inside the workbench 1. The air extraction chamber 12 is connected to the air extraction pump 9, and each air suction hole 11 is arranged at the top of the air extraction chamber 12. By arranging the air extraction chamber 12, the air suction operation of all the air suction holes 11 can be synchronously controlled, which is more convenient.

[0032] The second control structure in this embodiment includes a second control motor 4. The second mounting frame 8 is arranged on the first mounting frame 3. The third sliding rail 33 is fixedly arranged on the first mounting frame 3. The second mounting frame 8 is slidably connected to the third sliding rail 33 to prevent the second mounting frame 8 from slipping and being displaced. The second sliding rack 32 is fixedly arranged on the upper side of the first mounting frame 3. The second control motor 4 is fixedly connected to the second mounting frame 8. The second transmission gear 41 is rotatably arranged on the second mounting frame 8. The output shaft of the second control motor 4 is fixedly connected to the second transmission gear 41. The second transmission gear 41 meshes with the second sliding rack 32. In this embodiment, the forward and reverse rotation of the second control motor 4 is used to realize the Y - axis movement of the cutting member 5, which is convenient for the cutting member 5 to cut the cutting material.

[0033] The third control structure in this embodiment includes a telescopic member 81, the fixed end of the telescopic member 81 is fixedly connected to the second mounting bracket 8, and the telescopic end of the telescopic member 81 is fixedly connected to the cutting member 5. The telescopic member 81 used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Among them, the hydraulic cylinder or the cylinder are both existing technologies and are not described in detail in this embodiment. This embodiment uses the telescopic member 81 to control the Z axial movement of the cutting member 5, so that the cutting member 5 can approach or move away from the cutting material to achieve cutting of the cutting material. This embodiment uses a hydraulic cylinder or a cylinder to control the cutting member 5 to be close to the material to be cut, so that a buffering force is generated when the cutting tool contacts the material, thereby avoiding damage to the tool due to excessive stress.

[0034] The fourth control structure in this embodiment includes a third control motor 711, a first sliding member 71 slidingly disposed on the first sliding rail 21, a second sliding member 72 slidingly disposed on the second sliding rail 22, two sides of the cleaning roller 6 being rotationally connected to the first sliding member 71 and the second sliding member 72, respectively, so that the cleaning roller 6 abuts the workbench 1, a third control motor 711 fixedly connected to the first sliding member 71, a third transmission gear 712 rotationally disposed on the first sliding member 71, and a third transmission gear 712 fixedly connected to the output shaft of the third control motor 711. The cleaning roller 6 in this embodiment shares the first sliding rail 21 and the second sliding rail 22 with the first mounting member, thereby reducing the manufacturing cost of this embodiment. By moving the cleaning roller 6 to remove the slag from the workbench 1, the workbench can be automatically cleaned, which is more labor-saving.

[0035] The fifth control structure in this embodiment includes a fourth control motor 61, which is fixedly connected to the first sliding member 71. The output shaft of the fourth control motor 61 is fixedly connected to the cleaning roller 6. In this embodiment, the third control motor 711 controls the rotation direction of the cleaning roller 6, which is opposite to the direction of movement of the cleaning roller 6. This improves the ability to remove slag from the worktable 1. Furthermore, when the cleaning roller 6 retracts, the fourth control motor 61 can be turned off, and the cleaning roller 6 rotates in conjunction with the movement of the worktable 1, reducing the possibility of slag being carried back.

[0036] The working process of this embodiment is as follows: first, the cutting piece 5 is moved to one end away from the cleaning roller 6 by the first control motor 31, and then the fourth control motor 61 is started to rotate the cleaning roller 6, and then the third control motor 711 is started to move the cleaning roller 6 to take the scraps on the suction hole 11 away from the workbench 1, and then the fourth control motor 61 is turned off, and the second control motor 4 is started in reverse to make the cleaning roller 6 return to its original position, thereby completing the cleaning of the suction hole 11.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
