[0031] See also Figure 1-5 The utility model provides a technical solution: a multi-layer plastic film positioning and laminating device, including a base 1, a moving frame 2 is slidably connected to the upper surface of the base 1, a mounting frame 3 is slidably connected to the inner wall of the moving frame 2, a material roller 4 is installed on the inner wall of the mounting frame 3, a positioning frame 5 is fixedly connected to the upper surface of the base 1, two positioning plates 6 are installed inside the positioning frame 5, a cutting device 7 is provided on the side of the mounting frame 3, and a replacement device 8 is provided on the inner wall of the mounting frame 3.

[0032] The specific settings and functions of the cutting device 7 and the replacing device 8 are described in detail below.

[0033] like Figure 1-Figure 4As shown, the cutting device 7 includes a mounting bar 701, the mounting bar 701 is fixedly connected to the side of the mounting frame 3, the inner wall of the mounting bar 701 is slidably connected with a slide bar 702, and the end of the slide bar 702 close to the positioning frame 5 is fixedly connected with a cutting head 703. By setting the mounting bar 701, the slide bar 702 and the cutting head 703 can be installed on the mounting frame 3, the slide bar 702 slidably connected to the inner wall of the mounting bar 701 can move, and by setting the slide bar 702, the movement of the cutting head 703 can be controlled, so that the plastic film can be cut. A slide groove is provided on the upper surface of the moving frame 2, and a slider 710 is slidably connected to the surface of the slide groove on the moving frame 2, and a limit plate 705 is fixedly connected to the upper surface of the slider 710, and a clamping plate 704 is fixedly connected to the end of the slide bar 702 away from the cutting head 703. By providing the slider 710 , the limit plate 705 can be installed while ensuring that the limit plate 705 can move. By providing the limit plate 705 and the clamping plate 704 , the position of the slide bar 702 can be limited.

[0034] The inner wall of the slider 710 is slidably connected with a fixing rod 711, which is fixedly connected to the inner wall of the slide groove on the moving frame 2. The surface of the fixing rod 711 is covered with a first spring 712, and the two ends of the first spring 712 are respectively fixedly connected to the slider 710 and the moving frame 2. By setting the fixing rod 711, the position of the first spring 712 can be limited, and by setting the first spring 712, the position of the slider 710 can be limited. The side of the moving frame 2 is fixedly connected with an arc plate 706, and the inner wall of the arc plate 706 is threadedly inserted with a screw 707. The end of the screw 707 close to the base 1 is fixedly connected with a mounting plate 708, and the side of the mounting plate 708 away from the screw 707 is glued with a rubber pad 709. By setting the arc plate 706, the screw 707 can be installed, and by setting the screw 707, the mounting plate 708 and the rubber pad 709 can be controlled to move close to or away from the base 1, so that the position of the moving frame 2 can be limited or the restriction on the moving frame 2 can be released.

[0035] like Figure 1 and Figure 2 as well as Figure 5As shown, the replacement device 8 includes two connecting plates 81, and the two connecting plates 81 are fixedly connected to the side of the installation frame 3 close to the material roller 4, and the lower surfaces of the two connecting plates 81 are fixedly connected with a supporting plate 82. By setting the connecting plates 81, the supporting plate 82 can be moved, and by setting the supporting plate 82, the material roller 4 can be lifted. When the material roller 4 needs to be replaced, the connecting plate 81 can be controlled to move the supporting plate 82 away from the material roller 4, so as to facilitate the replacement of the material roller 4. Two fixed blocks 83 are fixedly connected to the side of the installation frame 3 close to the material roller 4, and the two fixed blocks 83 are fixedly connected to the side close to the connecting plate 81 with a connecting rod 84, and the connecting rod 84 is slidably connected to the inner wall of the connecting plate 81. By setting the fixed blocks 83, the connecting rod 84 can be connected to the installation frame 3, and by setting the connecting rod 84, the connection of the connecting plate 81 can be realized, and at the same time, the connecting plate 81 can be ensured to be movable.

[0036] One end of the connecting rod 84 away from the fixing block 83 is fixedly connected with a circular plate 85, and a second spring 86 is sleeved on the surface of the connecting rod 84, and the two ends of the second spring 86 are respectively fixedly connected to the connecting plate 81 and the fixing block 83. By providing the circular plate 85, the connecting plate 81 can be prevented from being separated from the connecting rod 84, and by providing the second spring 86, the position of the connecting plate 81 can be limited.

[0037] Working principle: When using the plastic film positioning and laminating device to laminate the plastic film, first place the device to be laminated with the plastic film inside the positioning frame 5 on the base 1, then use the positioning plate 6 to fix the device in position, install the material roller 4 on the mounting frame 3, move the material roller 4 close to the device to be laminated with the plastic film, move the moving frame 2 to laminate and press the plastic film, and complete the laminating work of the plastic film. After the plastic film is pasted, the movable frame 2 is moved so that the cutting head 703 is close to the position of the excess plastic film, the clamping plate 704 is grasped, and the limiting plate 705 is moved so that the slider 710 slides on the surface of the fixing rod 711 to release the restriction on the position of the slider 702. Then, the slider 702 is moved to slide on the inner wall of the mounting strip 701 so that the cutting head 703 is close to the plastic film, and the limiting plate 705 is released. Under the action of the elastic force of the first spring 712, the limiting plate 705 moves back to its original position. By observing the positional relationship between the cutting head 703 and the plastic film, the movable frame 2 is adjusted so that the cutting head 703 is aligned with the position of the plastic film to be cut, and the screw 707 is turned to make it rotate on the inner wall of the arc plate 706 so that the mounting plate 708 and the rubber pad 709 are close to each other. The base 1 limits the position of the movable frame 2, and then moves the sliding rod 702 to make the cutting head 703 cut the plastic film, moves the limiting plate 705 to make the first spring 712 contract, and moves the clamping plate 704 close to the limiting plate 705, loosens the limiting plate 705, and under the action of the elastic force of the first spring 712, the limiting plate 705 moves close to the clamping plate 704 to limit the position of the clamping plate 704, rotates the screw 707 to make the rubber pad 709 move away from the base 1, and releases the restriction on the position of the movable frame 2. By setting the cutting device 7, after using the plastic film positioning and bonding device to bond the plastic film to the equipment that needs to bond the plastic film, the excess plastic film can be cut, which facilitates the removal of the excess plastic film and improves the efficiency of bonding the plastic film.

[0038] When it is necessary to install the material roller 4, first move the connecting plate 81 to make it slide on the surface of the connecting rod 84. At this time, the connecting plate 81 drives the supporting plate 82 away from the fixed block 83, moves the material roller 4 close to the installation frame 3, and loosens the connecting plate 81. Under the action of the elastic force of the second spring 86, the connecting plate 81 drives the supporting plate 82 to move close to the material roller 4, so that the supporting plate 82 limits the position of the material roller 4, and completes the installation of the material roller 4. By setting the circular plate 85, the connecting plate 81 is prevented from being separated from the connecting rod 84. By setting the replacement device 8, it is convenient to disassemble and install the material roller 4 when using the plastic film positioning and bonding device for the bonding of the plastic film, thereby facilitating the installation of the plastic film to be bonded on the material roller 4, thereby facilitating the bonding of the plastic film.
