[0023] Specifically, the adjustment assembly 6 includes an adjustment seat 61, a rotating rod 62, a throttle 63, a first bevel gear 64, a second bevel gear 65, a lifting trapezoidal screw 66, a square slider 67, and a connecting assembly 68. The adjustment seat 61 is fixedly connected to the top of the support base 1. The rotating rod 62 is rotatably connected to the top of the adjustment seat 61 via a bearing. One end of the rotating rod 62 passes through the adjustment seat 61 and is fixedly connected to the throttle 63. The first bevel gear 64 is fixedly connected to the surface of the rotating rod 62. The second bevel gear 65 is meshed with one side of the first bevel gear 64. The lifting trapezoidal screw 66 is fixedly connected to one end of the second bevel gear 65. The lifting trapezoidal screw 66 and the adjustment seat 61 are rotatably connected via a bearing. The square slider 67 is threadedly connected to the surface of the lifting trapezoidal screw 66. The square slider 67 and the adjustment seat 61 are in close sliding connection. The connecting assembly 68 is provided at one end of the square slider 67.

[0024] By adopting the above technical solution, rotating the handle 63 will drive the rotating rod 62 to rotate, which in turn will drive the first bevel gear 64 to rotate, which will drive the second bevel gear 65 to rotate, which will drive the lifting trapezoidal screw 66 to rotate, which will drive the square slider 67 to move, which will drive the spring assembly 4 and the pressure roller 5 to move, thereby adjusting the height.

[0025] Specifically, the connecting assembly 68 includes a connecting seat 681, a square insert 682, a fixing rod 683, a pressing block 684, and a fixing spring 685. The connecting seat 681 is fixedly connected to one side of the square slider 67. The square insert 682 is tightly inserted into the lower part of the connecting seat 681.

[0026] By adopting the above technical solution, by pulling the fixing rod 683, the fixing rod 683 drives the extrusion block 684 to move and compress the fixing spring 685, so that the fixing rod 683 disengages from the fixing hole on one side of the square insert 682. Then, the spring assembly 4 and the extrusion roller 5 can be removed by separating the square insert 682 and the connecting seat 681, thus achieving the effect of convenient and quick assembly between the spring assembly 4 and the extrusion roller 5 and the adjustment assembly 6.

[0027] Specifically, the lower part of the connector 681 is provided with a socket for a square plug 682, and the side of the square plug 682 is provided with a fixing hole for a fixing rod 683.

[0029] In this embodiment, during use: rotating the handle 63 causes the rotating rod 62 to rotate, which in turn causes the first bevel gear 64 to rotate, which in turn causes the second bevel gear 65 to rotate, which in turn causes the lifting trapezoidal screw 66 to rotate, which in turn causes the square slider 67 to move, which in turn causes the spring assembly 4 and the pressure roller 5 to move, thus adjusting the height. By pulling the fixing rod 683, the fixing rod 683 causes the pressure block 684 to move and compress the fixing spring 685, causing the fixing rod 683 to disengage from the fixing hole on one side of the square insert 682. Then, the spring assembly 4 and the pressure roller 5 can be removed by separating the square insert 682 from the connecting seat 681. This achieves the effect of quick assembly of the spring assembly 4 and the pressure roller 5 with the adjusting assembly 6, making it easy to adjust the height of the pressure roller 5 during use and improving its practicality.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is as follows: Specifically, the dust filter assembly 8 includes a dust filter box 81, an internally threaded tube seat 82, an externally threaded tube seat 83, a dust filter cartridge 84, a cover plate 85, fixing screws 86, a rubber sealing gasket 87, and a positioning rod 88. The air inlet of the adsorption machine 7 is fixedly connected to the dust filter box 81, and the air inlet of the dust filter box 81 is fixedly connected to the adsorption device 9. An internally threaded tube seat 82 is fixedly connected to the air inlet inside the dust filter box 81. One end of the internally threaded tube seat 82 is threadedly connected to an externally threaded tube seat 83, and one end of the externally threaded tube seat 83 is fixedly connected to a dust filter cartridge 84. A cover plate 85 is installed on one side of the dust filter box 81, and a rubber sealing gasket 87 is fixedly connected to one side of the cover plate 85. Fixing screws 86 are inserted into both ends of the middle of the cover plate 85, and positioning rods 88 are symmetrically and fixedly connected to both ends of one side of the cover plate 85.

[0032] By adopting the above technical solution, the air sucked in by the adsorption machine 7 enters the dust filter box 81. The air enters the dust filter cartridge 84 through the internal threaded tube seat 82 and the external threaded tube seat 83, filtering out the dust. When it is necessary to remove and clean the dust filter cartridge 84, the fixing screw 86 is unscrewed, the cover plate 85 is removed, and then the dust filter cartridge 84 is unscrewed through the threaded connection for cleaning or replacement.

[0033] Specifically, positioning holes for the positioning rod 88 are provided at both ends of one side of the dust filter box 81, and threaded holes for the fixing screw 86 are provided in the middle of one side of the dust filter box 81.

[0034] By adopting the above technical solution, the positioning hole and positioning rod 88 cooperate to facilitate the positioning of the cover plate 85 during installation, and the threaded hole cooperates with the fixing screw 86 to facilitate the fixing between the cover plate 85 and the dust filter box 81.

[0035] In this embodiment, when the adsorption machine 7 is in use, the air drawn in enters the dust filter box 81. The air then passes through the internal threaded tube seat 82 and the external threaded tube seat 83 into the dust filter cartridge 84, filtering out the dust. When it is necessary to remove and clean the dust filter cartridge 84, the fixing screw 86 is unscrewed, the cover plate 85 is removed, and the dust filter cartridge 84 is unscrewed through the threaded connection for cleaning or replacement. This facilitates the filtration of the air drawn in by the adsorption machine 7, prevents dust and impurities from damaging it, and improves its practicality.

[0036] The structure and operating principle of the support base 1, conveyor belt assembly 2, conveying device 3, spring assembly 4, squeeze roller 5, adsorption machine 7, and adsorption device 9 in this utility model have been disclosed in the protective film sheet sorting device with bottom negative pressure adsorption conveyor belt disclosed in Chinese patent application No. 202323523826.X. Its working principle is as follows: the protective film sheet is discharged from the bottom of the conveying device 3, and then the conveyor belt is driven by the operation of the drive roller. The conveyor belt drives the film sheet to be conveyed and sorted, and then the squeeze roller 5 squeezes it to prevent the protective film sheet from curling up. Then, the anti-slip strip on the surface of the conveyor belt increases the friction between the conveyor belt and the protective film sheet. Finally, the adsorption machine 7 drives the adsorption device 9 to adsorb the protective film sheet.

[0037] The working principle and usage process of this utility model are as follows: This utility model is used for conveying and sorting protective film sheets. The protective film sheets are discharged from the bottom of the conveyor 3 and then conveyed by the conveyor belt assembly 2. The spring assembly 4 and the squeeze roller 5 work together to squeeze the protective film sheets, preventing them from curling up. The adsorption machine 7 drives the adsorption device 9 to adsorb the protective film sheets. The air entering the adsorption machine 7 is filtered by the dust filter assembly 8. The height of the squeeze roller 5 can be adjusted as needed by the adjustment assembly 6. When using the adjustment assembly 6, rotating the handle 63 drives the rotating rod 62, which in turn drives the first bevel gear 64. The first bevel gear 64 drives the second bevel gear 65, which in turn drives the lifting trapezoidal screw 66. The lifting trapezoidal screw 66 moves the square slider 67, which in turn moves the spring assembly 4 and the squeeze roller 5, allowing for height adjustment. The height can be adjusted by pulling the fixing rod 6. 83. The fixing rod 683 drives the squeezing block 684 to move and compress the fixing spring 685, causing the fixing rod 683 to disengage from the fixing hole on one side of the square insert 682. Then, the spring assembly 4 and the squeezing roller 5 can be removed by separating the square insert 682 and the connecting seat 681. This achieves the effect of quick assembly between the spring assembly 4 and the squeezing roller 5 and the adjusting assembly 6. This allows the height of the squeezing roller 5 to be easily adjusted during use, improving the practicality of the device. When the dust filter assembly 8 is in use, the air sucked in by the adsorber 7 enters the dust filter box 81. The air enters the dust filter cartridge 84 through the internal threaded tube seat 82 and the external threaded tube seat 83, filtering out the dust. When it is necessary to remove and clean the dust filter cartridge 84, the fixing screw 86 is unscrewed, the cover plate 85 is removed, and the dust filter cartridge 84 is unscrewed through the threaded connection for cleaning or replacement. This facilitates the filtration of the air sucked in by the adsorber 7, prevents dust and impurities from damaging it, and improves the practicality of the device.
