[0002] A Chinese patent with announcement number CN220110629U discloses a plastic film rapid laminating machine. In view of the problem in the prior art that in actual use, negative pressure will absorb moving debris such as dust and particulate matter, which will cause the dust and particulate matter that cannot pass through the dust filter to be stuck in the mesh of the dust filter, causing the dust filter to be blocked and inconvenient to use, the following solution is proposed, which includes a shell, a negative pressure motor, a transmission motor and a dust filter, the negative pressure motor is fixedly connected to the inner wall of the shell, the inner wall of the shell is fixedly connected to a dust filter box and a control box, the dust filter is movably connected to the inner wall of the dust filter box, the inner wall of the dust filter box is rotatably connected to a rotating wheel, and the front side of the rotating wheel is fixedly connected to a knocking rod, and through the cooperation of the transmission motor and the reciprocating mechanism, the dust filter can be easily cleaned to prevent the dust filter from being blocked and affecting the use, and the solution has strong practicality.

[0025] Specific application examples of the utility model:

[0026] A negative pressure motor 2 is fixedly installed at the exhaust end of the laminating machine 1. The negative pressure motor 2 can generate negative pressure through the rotation of the internal motor, thereby sucking out the dust inside the laminating machine 1, so that the inside of the laminating machine 1 remains relatively clean. A dust filter box 3 is fixedly installed at the air inlet end of the laminating machine 1 to remove dust from the gas entering the laminating machine 1 through the air inlet end. The upper part of the dust filter box 3 is connected to the air inlet end of the laminating machine 1, and an air inlet is provided at the lower part of the dust filter box 3. A filter screen 31 is provided between the air inlet and the air outlet, so that the gas passes through the filter screen 31 from the lower side of the filter screen 31 and enters the laminating machine 1. A cleaning component 5 is provided in the dust filter box 3. The cleaning component 5 is located at the lower side of the filter screen 31. Since the gas passes through the filter screen 31 from the lower side of the filter screen 31 and enters the laminating machine 1, most of the dust is located at the lower side of the filter screen 31, which is convenient for the cleaning component 5 to clean the filter screen 31. The cleaning component 5 is located at the lower side of the filter screen 31, which is conducive to the dust falling due to weight after separation from the filter screen 31. The cleaning assembly 5 includes a brush plate 51 that matches the filter screen 31. The brush plate 51 moves along the first guide rail 33 and the second guide rail 34 in the dust filter box 3. The first guide rail 33 and the second guide rail 34 are arranged in parallel to each other to limit the moving path of the brush plate 51. The first telescopic assembly 52 can be made of an electric telescopic rod. The first telescopic assembly 52 is arranged parallel to the first guide rail 33 to drive the brush plate 51 to move.

[0027] The cover plate 4 is arranged on the upper side of the filter 31. When the cleaning component 5 cleans the filter 31, the cover plate 4 covers the upper side of the filter 31 to prevent dust from passing through the filter 31 accidentally during the cleaning process. The cover plate 4 is connected to the mounting frame 32 through the connecting block 6 to fix the cover plate 4. The second telescopic component 61 can be made of an electric telescopic rod. The second telescopic component 61 is hingedly connected to the connecting block 6 and the cover plate 4, so as to drive the cover plate 4 to rotate around the connecting block 6. An abutment block 41 is provided on the side of the cover plate 4 close to the filter 31. The abutment block 41 and the filter 31 abut and match each other, which is conducive to supporting and abutting the side of the filter 31 away from the cleaning component 5 when the cleaning component 5 cleans the filter 31, so as to avoid deformation of the filter 31 under the action of the cleaning component 5 during the cleaning process. A support block 35 is provided on the mounting frame 32 and is located between the two groups of connecting blocks 6. The support block 35 and the cover plate 4 are abutted against each other to support the end of the cover plate 4 away from the connecting block 6, ensuring that the cover plate 4 and the filter screen 31 remain parallel.
