[0025] By adopting the above technical solution,.

[0026] Specifically, the air intake filter assembly 3 includes a vibration device 31, a fiber filter plate 32, a positioning slot 34, a mounting cylinder 35 and an air outlet plate 36, wherein the mounting cylinder 35 is inserted into one end of the interior of the base cylinder 6, and the air outlet plate 36 is provided on one side of the interior of the mounting cylinder 35. The vibration device 31 is provided on one side of the air outlet plate 36, and the fiber filter plate 32 is provided on one side of the vibration device 31.

[0028] Specifically, a dust shield 33 is provided at the bottom end of the installation cylinder 35 on a side away from the air outlet plate 36 .

[0029] By adopting the above technical solution, impurities fall on the bottom end of the installation cylinder 35 and are blocked by the dust shield 33 so as to be processed later, thereby improving the use effect of the equipment.

[0030] Specifically, a positioning seat is provided on the inner wall surface of the base cylinder 6 corresponding to the positioning slot 34 , and a damping pad is provided on the surface of the positioning seat.

[0033] By adopting the above technical solution, compressed air is injected into the interior of the base cylinder 6 through the air inlet 5. The air entering the interior of the base cylinder 6 is filtered by the fiber filter plate 32. The fiber filter plate 32 is forced to move along the guide rod 313 and the limit spring 312 is compressed.

The air entering the base cylinder 6 is filtered by the fiber filter plate 32. The fiber filter plate 32 is forced to move along the guide rod 313 and compress the limit spring 312. When the air flow stops or fluctuates, the limit spring 312 pushes the fiber filter plate 32 to vibrate, so as to shake off the attached impurities, thereby improving the convenience of cleaning the fiber filter plate 32 and ensuring the filtration quality.

[0035] The impurities shaken off fall on the bottom end of the mounting tube 35 and are blocked by the dust shield 33 so as to be processed later, thereby improving the use effect of the equipment.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that: specifically, the positioning and installation component 2 includes a plug-in column 21, a positioning groove 22, a positioning block 23 and a glue injection hole 24, wherein a positioning block 23 is symmetrically provided at one end of the base cylinder 6, and a plurality of glue injection holes 24 are opened inside the positioning block 23, and a positioning groove 22 is opened at one end of the supporting plate 1 corresponding to the positioning block 23, and a plug-in column 21 is provided inside the positioning groove 22.

[0038] By adopting the above technical solution, when the base cylinder 6 is used, it is necessary to first install the supporting plate 1 on the surface of the base cylinder 6, inject glue into the glue injection hole 24 inside the positioning block 23, and then plug the positioning groove 22 at one end of the supporting plate 1 into the corresponding positioning block 23. At this time, the plug-in column 21 is inserted into the plug-in groove inside the positioning block 23, and the plug-in column 21 is glued and fixed to the inside of the positioning block 23 by glue. At this time, the exhaust holes 8 opened on the surface of the supporting plate 1 correspond one-to-one with the exhaust holes 7 opened on the surface of the base cylinder 6, preventing the situation of misalignment causing airflow obstruction, ensuring the stability of the equipment use, and improving the support effect of the film.

[0039] Specifically, an inserting groove is provided inside the positioning block 23 corresponding to the inserting column 21 , and a positioning hole is symmetrically provided at one end of the supporting plate 1 away from the inserting column 21 .

[0040] By adopting the above technical solution, the plug-in columns 21 at one end of multiple groups of carrier plates 1 can be plugged into the corresponding positioning holes, so that multiple groups of carrier plates 1 can be accurately installed at the same time, reducing positioning costs and improving installation efficiency.

[0041] When using this embodiment: When the base cylinder 6 is used, it is necessary to first install the carrier plate 1 on the surface of the base cylinder 6, inject glue into the glue injection hole 24 inside the positioning block 23, and then plug the positioning groove 22 at one end of the carrier plate 1 into the corresponding positioning block 23. At this time, the plug-in column 21 is inserted into the plug-in groove inside the positioning block 23, and the plug-in column 21 is glued and fixed to the inside of the positioning block 23 by glue. At this time, the exhaust holes 8 opened on the surface of the carrier plate 1 correspond one-to-one with the exhaust holes 7 opened on the surface of the base cylinder 6 to prevent misalignment from causing airflow obstruction, ensure the stability of the equipment, improve the support effect of the film, and the plug-in columns 21 at one end of multiple groups of carrier plates 1 can be plugged into the corresponding positioning holes, so as to accurately install multiple groups of carrier plates 1 at the same time, reduce positioning costs, and improve installation efficiency.

[0042] The working principle and use process of the present invention: When the present invention is in use, an air flotation roller needs to be used to protect the film during the film transmission process to prevent the film from directly contacting the surface of the base cylinder 6 and causing damage to the film. When the base cylinder 6 is in use, the supporting plate 1 needs to be installed on the surface of the base cylinder 6 first, and glue is injected into the glue injection hole 24 inside the positioning block 23. Then, the positioning groove 22 at one end of the supporting plate 1 is correspondingly plugged into the positioning block 23. At this time, the plug-in column 21 is inserted into the plug-in groove inside the positioning block 23, and the plug-in column 21 is glued and fixed to the inside of the positioning block 23 by glue. At this time, the exhaust holes 8 opened on the surface of the supporting plate 1 correspond to the exhaust holes 7 opened on the surface of the base cylinder 6, preventing the situation of misalignment causing airflow obstruction, ensuring the stability of the equipment, and improving the supporting effect of the film. In addition, the plug-in columns 21 at one end of multiple groups of supporting plates 1 can be plugged into the positioning holes accordingly, so that multiple groups of supporting plates 1 can be accurately installed at the same time, reducing positioning costs and improving installation efficiency.

[0043] Compressed air is then injected into the interior of the base cylinder 6 through the air inlet 5. The air entering the base cylinder 6 is filtered by the fiber filter plate 32. The fiber filter plate 32 is forced to move along the guide rod 313 and compress the limit spring 312. When the air flow stops or fluctuates, the limit spring 312 pushes the fiber filter plate 32 to vibrate, so as to shake off the attached impurities, thereby improving the convenience of cleaning the fiber filter plate 32 and ensuring the filtration quality.

[0044] The impurities shaken off fall on the bottom end of the mounting tube 35 and are blocked by the dust shield 33 so as to be processed later, thereby improving the use effect of the equipment.
