[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a glass fiber cloth dust collector filter bag structure, including a fixing mechanism 1, which includes a mounting base 11. The mounting base 11 has a through hole 111 in the center. A rotating ring 12 is rotatably mounted inside the mounting base 11. The rotating ring 12 has multiple sets of internal gear teeth 121 inside. Multiple half gears 13 are rotatably mounted on the mounting base 11. The multiple half gears 13 mesh with the corresponding internal gear teeth 121. A clamping plate 131 is fixedly mounted on the half gears 13. A set of external gear teeth 122 is provided on the outer wall of the rotating ring 12. A drive gear 14 that meshes with the external gear teeth 122 is rotatably mounted on the mounting base 11.

[0017] A handwheel can be installed on the drive gear 14, which is convenient for the hand to drive the drive gear 14 to rotate. The gear transmission drives the rotating ring 12 to rotate. The rotating ring 12 drives the half gear 13 to rotate through multiple sets of internal gear teeth 121, thereby driving the clamping plate 131 to rotate. The clamping plate 131 fixes the filter bag body 3. When the rotating ring 12 rotates clockwise, the multiple clamping plates 131 clamp the filter bag body 3. When the rotating ring 12 rotates counterclockwise, the multiple clamping plates 131 release the filter bag body 3, which facilitates the disassembly of the filter bag body 3 and the support mechanism 2.

[0018] The support mechanism 2 includes a support ring 21, on the outer wall of which a filter bag body 3 is fitted. The outer wall of the support ring 21 is provided with an annular groove 211, which cooperates with multiple clamping plates 131. The inner wall of the through hole 111 is provided with an annular support step 112, which cooperates with the support ring 21.

[0019] The filter bag body 3 is tensioned by the support ring 21, and the card plate 131 engages with the card slot 211 after contacting the filter bag body 3, thereby fixing the filter bag body 3, and the position of the support ring 21 is restricted by the support step 112.

[0020] Multiple frames 22 are fixedly installed on the bottom wall of the support ring 21. The multiple frames 22 are evenly distributed on the bottom wall of the support ring 21. A rotating frame 221 is rotatably installed at the bottom end of each of the multiple frames 22. A rotating screw 23 is rotatably installed on each of the multiple frames 22 via a bracket. A lifting nut 231 is threadedly connected to the rotating screw 23. Multiple transmission rods 232 are rotatably connected to the outer wall of the lifting nut 231. Each of the multiple transmission rods 232 is rotatably connected to the lifting nut 231 at one end and to the corresponding rotating frame 221 at the other end.

[0021] Furthermore, the inner wall of the filter bag body 3 is supported by the frame 22. The rotating screw 23 can be rotated to drive the lifting nut 231 to rise, thereby driving the rotating frame 221 to rotate through multiple transmission links 232. This allows the multiple rotating frames 221 to fold, making it easier to insert the frame 22 into the filter bag body 3. Rotating the rotating screw 23 drives the lifting nut 231 to fall, thereby driving the rotating frame 221 to rotate through multiple transmission links 232. This allows the multiple rotating frames 221 to unfold, supporting the inner wall of the filter bag body 3 and tensioning the filter bag body 3.

[0022] The filter bag body 3 includes a filter bag base layer 31. The inner wall of the filter bag base layer 31 is provided with an inner wear-resistant layer 32, the outer wall of the filter bag base layer 31 is provided with an outer wear-resistant layer 33, and the outer surface of the outer wear-resistant layer 33 is provided with a high-temperature resistant layer 34.

[0023] Specifically, the filter bag base layer 31 is made of glass fiber, and both the outer wear-resistant layer 33 and the inner wear-resistant layer 32 can be carbon fiber layers, thereby improving the wear resistance of the filter bag base layer 31. The high-temperature resistant layer 34 can be a nylon fiber layer, which improves the high-temperature resistance of the filter bag body 3, prevents dust from generating heat through long-term friction, and extends the service life of the filter bag body 3.

[0024] The workflow of this embodiment is as follows: Please refer to... Figure 1-5A fiberglass cloth dust collector filter bag structure, wherein the inner wall of the filter bag body 3 is supported by a frame 22, a rotatable screw 23 can be rotated to drive the lifting nut 231 to rise, thereby driving the rotating frame 221 to rotate through multiple transmission links 232, causing the multiple rotating frames 221 to fold, making it easy to insert the frame 22 into the filter bag body 3. Rotating the screw 23 can also drive the lifting nut 231 to fall, thereby driving the multiple transmission links 232 to rotate the rotating frames 221, causing the multiple rotating frames 221 to unfold, supporting the inner wall of the filter bag body 3, and tensioning the filter bag body 3, which is then tensioned by a support ring 21. The inner wall drives the gear 14 to rotate, which in turn drives the rotating ring 12 to rotate. The rotating ring 12 drives the half gear 13 to rotate through multiple sets of internal gear teeth 121, thereby driving the clamping plate 131 to rotate. After the clamping plate 131 contacts the filter bag body 3, it engages with the clamping groove 211, thus fixing the filter bag body 3. When the rotating ring 12 rotates clockwise, the multiple clamping plates 131 clamp the filter bag body 3. When the rotating ring 12 rotates counterclockwise, the multiple clamping plates 131 release the filter bag body 3, making disassembly more convenient. Moreover, dusty air enters from the outside of the filter bag body 3, and the filtered air is discharged from the inside after being filtered by the filter bag body 3.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
