[0031] Please refer to Figures 1-4A cutting device for hot melt pressure-sensitive adhesive for bonding magnesium oxide boards includes a machine base 1 and a frame 2 fixedly connected to the bottom of the machine base 1. A bracket 3 is installed on the upper surface of the machine base 1, and a double-acting cylinder 4 is installed at the top of the bracket 3.

[0032] The movable end of the double-acting cylinder 4 is fixedly connected to a mounting plate 5. The upper surface edge of the mounting plate 5 is symmetrically fixedly connected to ear plates 6. A double-headed screw 7 is rotatably connected between the ear plates 6. A servo motor 8 with a power output end and a transmission connection to the double-headed screw 7 is installed on the surface of one of the ear plates 6. A guide hole 9 is opened on the edge of the mounting plate 5 away from the ear plate 6.

[0033] A tool holder 10 is installed below the mounting plate 5, and a cutting blade is installed on the lower surface of the tool holder 10. A guide block 11 that is slidably connected to the guide hole 9 is symmetrically installed on the upper surface of the tool holder 10. A connecting lug 12 that penetrates the mounting plate 5 and is screwed to the double-ended screw 7 is symmetrically installed on the edge of the upper surface of the tool holder 10 away from the guide block 11.

[0034] Below the cutting blade is a feeding hole 17 opened on the surface of the machine base 1. Above the feeding hole 17 is a boss 16 fixedly connected to the upper surface of the machine base 1. A second electric push rod 18 is installed on the side wall of the boss 16 away from the feeding hole 17. A push plate 19 located inside the boss 16 is installed on the movable end of the second electric push rod 18.

[0035] It should be noted that, in use, the hot melt pressure-sensitive adhesive cutting device for bonding magnesium oxide boards works by placing the hot melt pressure-sensitive adhesive block inside the boss 16, and using the second electric push rod 18 to push the hot melt pressure-sensitive adhesive block with the push plate 19 to move and cut it. By connecting the servo motor 8 to an external control device, the control device sets a suitable forward and reverse rotation program for the servo motor 8. The servo motor 8 drives the double-headed screw 7 to rotate, and the connecting ear 12 rotates in conjunction with the double-headed screw 7. At the same time, the guide block 11 slides in conjunction with the guide hole 9, which can adjust the spacing between the cutting blades installed at the cutter holder 10. Thus, the hot melt pressure-sensitive adhesive block can be cut into different thicknesses according to the requirements, improving the applicability of the device. The cut sheet of hot melt pressure-sensitive adhesive falls through the feeding hole 17.

[0037] It should be noted that after the hot melt pressure-sensitive adhesive is cut, the movable end of the first electric push rod 15 extends and comes into contact with the sheet-like hot melt pressure-sensitive adhesive, which can separate the hot melt pressure-sensitive adhesive from the cutting blade, which is beneficial for the hot melt pressure-sensitive adhesive to be fed.

[0038] like Figure 3As shown, the side wall of the guide block 11 is provided with a pointer 13, one side of the pointer 13 is provided with a scale line 14 engraved on the upper surface of the mounting plate 5, and the zero scale of the scale line 14 is arranged at the central position;

[0039] It should be noted that the distance between the two cutting blades can be accurately adjusted by using the scale on the pointer 13 corresponding to the scale line 14, thereby improving the slitting accuracy of the hot melt pressure sensitive adhesive.

[0040] As shown in the drawings, Figure 1 The push plate 19 is arranged in an inverted L-shaped structure, the inner side of the boss 16 is placed with a hot melt pressure sensitive adhesive block, and the end upper surface of the hot melt pressure sensitive adhesive block is in close contact with the inner side top wall of the bent end of the push plate 19.

[0041] It should be noted that the tail end of the hot melt pressure sensitive adhesive is prevented from being raised during the slitting process to ensure normal slitting of the hot melt pressure sensitive adhesive.

[0042] As shown in the drawings, Figure 4 The inner side of the boss 16 is symmetrically provided with a guide strip 20 fixedly connected with the upper surface of the machine table 1, and the side wall of the guide strip 20 is in close contact with the side wall of the hot melt pressure sensitive adhesive block.

[0043] It should be noted that the hot melt pressure sensitive adhesive block is guided during movement by the guide strip 20 to prevent it from deviating, thereby ensuring the uniformity of the slitting of the hot melt pressure sensitive adhesive after slitting.

[0044] In use: the hot melt pressure sensitive adhesive block is placed on the inner side of the boss 16, the second electric push rod 18 pushes the hot melt pressure sensitive adhesive block to move for slitting by the push plate 19, the control device is connected to the servo motor 8, the control device sets a suitable forward and reverse program for the servo motor 8, the servo motor 8 drives the double-headed screw 7 to rotate, the connecting lug 12 cooperates with the double-headed screw 7 to rotate in, and the guide block 11 cooperates with the guide hole 9 to slide, so as to adjust the distance between the cutting blades installed at the tool holder 10, thereby the hot melt pressure sensitive adhesive block can be cut into different thicknesses according to the requirements, and the sheet-shaped hot melt pressure sensitive adhesive after slitting falls through the discharging hole 17.

[0045] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical scheme and improvement concept of the present application, which should be covered within the protection scope of the present application.
