However, traditional filter bags often fall off during use due to insufficient fastening. Furthermore, replacing the filter bags requires considerable time and effort, and the process is complex and cumbersome. Utility Model Content

[0024] See also Figure 1-5As shown, the utility model is a negative pressure inner filter bag dust collector anti-bag falling mechanism, including a dust collector device body 1 and a flower plate 2.

The top of the second connecting shaft 410 is fixedly connected with a twisting plate 411. By setting an anti-slip fixing mechanism 4, the filter bag can be quickly replaced, thereby improving the maintenance and operation efficiency of the entire dust removal system. The four snap-fit ​​strips 49 and the snap-fit ​​installation design that closely matches the inner wall of the mounting plate 41 allow the filter bag to be firmly fixed to prevent it from falling off due to insufficient fixation.

[0025] The anti-slip fixing mechanism 4 includes four half gears 42, which are distributed in a ring array on the top of the flower plate 2. The four half gears 42 are all engaged with the ring gear 43, and the four snap strips 49 are all slidingly connected to the mounting plate 41, and the ring gear 43 is engaged with the transmission gear 44.

[0026] There are six bag holes 3 and anti-slip fixing mechanisms 4, and they are distributed in a rectangular array on the flower plate 2. Each dust collector is provided with a plurality of filter bags of different quantities, not limited to six filter bags. This article only expresses the problem solved by the technical solution.

[0027] The bottom of the dust collector device body 1 is fixedly connected to a support block 5, the bottom of the support block 5 is fixedly connected to a support column 6, the back of the dust collector device body 1 is fixedly connected to an L-shaped fixed block 7, and a vibration-promoting removal mechanism 8 is arranged between the L-shaped fixed block 7 and the flower plate 2. By setting up the vibration-promoting removal mechanism 8, the flower plate 2 and the filter bag can be driven to generate mechanical vibration through reciprocating motion, which helps to loosen and fall off the dust layer on the surface of the filter bag, thereby improving the cleaning efficiency on the basis of traditional pulse blowing, and is particularly effective for processing dust with strong viscosity or fine particles.

[0028] The vibration-induced removal mechanism 8 includes a motor 81, a limiting sleeve 82, and a connecting rod 83. The motor 81 is electrically connected to an external power source and is controlled by an external program. The motor 81 is fixedly connected to the front of the L-shaped fixing block 7, the limiting sleeve 82 is fixedly connected to the inner wall of the dust collector device body 1, and the connecting rod 83 is fixedly connected to the top of the flower plate 2. The output end of the motor 81 is fixedly connected to a transmission arm 84, and the front of the transmission arm 84 is fixedly connected to a transmission shaft 85.

The top of the connecting rod 83 is fixedly connected to a connecting block 88, and the rotating shaft 87 and the connecting block 88 are rotatably connected.

[0029] The inner wall of the dust collector device body 1 is fixedly connected with a fixed plate 9, and the top of the fixed plate 9 is fixedly connected with two limit rods 10. The two limit rods 10 are slidably connected to the flower plate 2. The design of the two limit rods 10 ensures that the entire vibration-induced removal mechanism 8 performs a stable linear up and down reciprocating motion.

[0030] There are four support blocks 5 , which are distributed in a rectangular array at the bottom edge of the dust collector device body 1 . The design of multiple support blocks 5 and support columns 6 ensures the stability of the equipment.

[0031] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0032] The working principle of the present invention is as follows: first, the filter bag body 46 is placed in the bag hole 3 through the mounting plate 41, and the mounting plate 41 is initially slid and inserted into the flower plate 2 through the insertion rod 45. Then, the screwing plate 411 is screwed and the transmission gear 44 is driven to rotate through 410. Since the transmission gear 44 is engaged with the ring gear 43, the ring gear 43 will also rotate accordingly. The rotation of the ring gear 43 will drive the four half gears 42 engaged with it to rotate synchronously through their respective adjacent first connecting shafts 47. The four half gears 42 are distributed in a ring array on the top of the flower plate 2. Each half gear 42 is connected to the buckle strip 49 through the connecting strip 48. As the half gear 42 rotates, the buckle strip 49 will slide along the inner wall of the mounting plate 41 and gradually clamp the mounting plate 41, thereby achieving The filter bag 46 is firmly fixed to prevent it from falling off during operation. When the dust on the filter bag 46 needs to be cleaned, the motor 81 is started. The motor 81 drives the transmission arm 84 at the output end to rotate, thereby driving the transmission shaft 85 and the transmission block 86 on its outer surface to move. The transmission block 86 is connected to the connecting block 88 through the rotating shaft 87, and the connecting block 88 is fixedly connected to the top of the connecting rod 83. Since the connecting rod 83 is slidingly connected to the limit sleeve 82, when the transmission block 86 moves, it will drive the connecting rod 83 to move back and forth up and down in the limit sleeve 82. The up and down movement of the connecting rod 83 is transmitted to the filter bag 46 through the flower plate 2, causing it to vibrate. This vibration helps to shake off the dust on the filter bag 46 and achieve the purpose of cleaning.
