Technical Field
[0001] This utility model relates to the field of blended filter bag technology, and in particular to an adaptive adjustment limiting structure for blended filter bags. Background Technology
[0002] In modern industrial production, blended filter bags have become key filtration equipment in many industries due to their excellent filtration performance and wide range of applications. Among them, filter bags are used as filtration components in dust collectors, which enable the dust collector to have basic filtration functions by being inserted into the filter port of the dust collector.
[0003] In the process of using blended filter bags, traditional installation methods usually use snap-on and bolt structures to securely install the filter bags. However, when faced with filter bags of different sizes, it is impossible to flexibly adjust and securely install them according to the size of the filter bags.
[0004] Therefore, to address the aforementioned problem of inconvenience in flexibly adjusting and securely installing filter bags of different sizes, an adaptive adjustment and limiting structure can be designed for blended filter bags. During the use of the blended filter bag, the two sets of arc-shaped limiting seats move synchronously and parallel to the center until their inner walls are in close contact with the side walls of the upper mounting cylinder of the filter bag body. Through the design of the adaptive adjustment and limiting structure, the effect of flexibly adjusting and securely installing filter bags of different sizes can be achieved. Utility Model Content
[0005] In order to overcome the problem that the traditional installation method of blended filter bags usually relies on manual adjustment and fixing devices, this method is particularly cumbersome and inflexible when dealing with filter bags of varying sizes, especially in situations where frequent filter bag replacement is required. It is time-consuming and laborious and urgently needs to be improved, as it is inconvenient to flexibly adjust and securely install filter bags of different sizes.
[0006] The technical solution of this utility model is as follows: a self-adjusting limiting structure for blended filter bags, including an installation ring seat, an inner cavity, a slide rail, an adjusting shaft, an adjusting gear, an upper toothed plate, a lower toothed plate, a guide groove, a guide rod, a guide seat, an arc-shaped limiting seat, a filter bag body, and an installation cylinder. The installation ring seat has an inner cavity, and a slide rail is fixedly installed inside the inner cavity. An adjusting shaft is rotatably installed inside the slide rail. An adjusting gear is fixedly installed on the side wall of the adjusting shaft. An upper toothed plate is installed on the upper side of the adjusting gear, and a lower toothed plate is installed on the lower side of the adjusting gear. Two sets of guide grooves are opened on both sides of the bottom wall of the installation ring seat. A guide rod is fixedly installed inside the guide groove. Two sets of guide seats are installed on both sides of the side wall of the guide rod. Two sets of arc-shaped limiting seats are installed on both sides of the bottom of the installation ring seat. The filter bag body is installed below the installation ring seat, and an installation cylinder is fixedly installed at the upper end of the filter bag body.
[0007] Preferably, during the use of the blended filter bag, firstly, the upper end of the mounting cylinder is tightly fitted with the lower end of the mounting ring seat. Then, a set of arc-shaped limiting seats is pushed inward to move parallel. The upper end of the set of arc-shaped limiting seats can push a set of guide seats and an upper toothed plate to move parallel inward along the guide rod. Since the upper toothed plate meshes with the upper side of the adjusting gear, the upper toothed plate can drive the adjusting gear to rotate. Since the lower side of the adjusting gear meshes with the lower toothed plate, the adjusting gear can drive the lower toothed plate to move parallel inward. The lower toothed plate can drive another set of guide seats and another set of arc-shaped limiting seats to move parallel inward along the guide rod. This allows the two sets of arc-shaped limiting seats to move parallel inward towards the center simultaneously until their inner walls are tightly abutting against the side wall of the mounting cylinder at the upper end of the filter bag body. At this time, the two sets of arc-shaped limiting seats tightly hold the side wall of the mounting cylinder, ensuring the stable installation of the filter bag body in the mounting ring seat. Throughout the process, through the design of the adaptive adjustment limiting structure, the effect of flexible adjustment and stable installation of filter bags of different sizes can be achieved.
[0008] Preferably, the upper toothed plate meshes with the upper side of the adjusting gear, the lower toothed plate meshes with the lower side of the adjusting gear, the guide seat is slidably connected to the guide rod, the upper end of one set of guide seats is fixedly connected to one end of the upper toothed plate, the upper end of another set of guide seats is fixedly connected to the bottom wall of the lower toothed plate, and both sides of the arc-shaped limiting seat are fixedly connected to the bottom walls of the two guide seats.
[0009] Preferably, a slide rod is fixedly installed inside the slide rail, and a slide seat is provided on the side wall of the slide rod. The slide seat is slidably connected to the slide rod, and the upper end of the upper toothed plate is fixedly connected to the bottom wall of the slide seat.
[0010] Preferably, a side plate is fixedly installed on one side of the bottom wall of the mounting ring seat, and a push-pull rod is installed inside the side plate. The push-pull rod is slidably connected to the side plate, and one end of the push-pull rod is fixedly connected to the side wall of a set of arc-shaped limiting seats.
[0011] Preferably, a fixing plate is fixedly installed on the bottom wall of the side plate, and a positioning rod is installed inside the fixing plate. The positioning rod is slidably connected to the fixing plate. Multiple positioning holes are opened on the bottom wall of the other end of the push-pull rod. The upper end of the positioning rod is engaged with the positioning hole. A limit ring is fixedly installed on the lower side wall of the positioning rod. A return spring is fixedly installed on the upper end of the limit ring. The upper end of the return spring is fixedly connected to the bottom wall of the fixing plate.
[0012] Preferably, a limiting edge is fixedly provided on the side wall of the mounting cylinder, and an annular protrusion is fixedly provided at the upper end of the limiting edge. An mounting hole is provided inside the mounting ring seat, and an annular groove is provided on the bottom wall of the mounting hole. The annular protrusion and the annular groove are in contact and connected.
[0013] Preferably, two sets of limiting grooves are provided on both sides of the bottom wall of the mounting ring seat. A protrusion is fixedly provided on the inner wall of the limiting groove. Two sets of limiting blocks are fixedly provided on both sides of the limiting edge. A limiting hole is provided through the inside of the limiting block. The limiting block is engaged with the protrusion through the limiting hole. The inner walls of the arc-shaped limiting seats on both sides are in contact with the sides of the mounting cylinder.
[0014] The beneficial effects of this utility model are:
[0015] During the use of blended filter bags, firstly, the upper end of the mounting cylinder is tightly fitted with the lower end of the mounting ring seat. Then, a set of arc-shaped limiting seats is pushed inward to move parallel. The upper end of the set of arc-shaped limiting seats can push a set of guide seats and an upper toothed plate to move parallel inward along the guide rod. Since the upper toothed plate meshes with the upper side of the adjusting gear, the upper toothed plate can drive the adjusting gear to rotate. Since the lower side of the adjusting gear meshes with the lower toothed plate, the adjusting gear can drive the lower toothed plate to move parallel inward. The lower toothed plate can then drive another set of guide seats and another set of arc-shaped limiting seats to move parallel inward along the guide rod. This allows the two sets of arc-shaped limiting seats to move parallel inward towards the center simultaneously until their inner walls are tightly abutting against the side wall of the mounting cylinder at the upper end of the filter bag body. At this point, the two sets of arc-shaped limiting seats tightly hold the side wall of the mounting cylinder, ensuring the stable installation of the filter bag body in the mounting ring seat. Throughout the process, through the design of the adaptive adjustment limiting structure, the effect of flexible adjustment and stable installation of filter bags of different sizes can be achieved.

A filter bag body 12 is provided below the mounting ring seat 1. An installation cylinder 13 is fixedly installed at the upper end of the filter bag body 12.
[0025] Please see Figure 1 and Figure 5The upper gear plate 6 meshes with the upper side of the adjusting gear 5, and the lower gear plate 7 meshes with the lower side of the adjusting gear 5. The guide seat 10 is slidably connected to the guide rod 9. The upper end of one set of guide seats 10 is fixedly connected to one end of the upper gear plate 6, and the upper end of the other set of guide seats 10 is fixedly connected to the bottom wall of the lower gear plate 7. Both sides of the arc-shaped limiting seat 11 are fixedly connected to the bottom walls of the two guide seats 10. The upper gear plate 6 can drive the adjusting gear 5 to rotate, and the adjusting gear 5 can drive the lower gear plate 7 to move inward in parallel. The lower gear plate 7 can drive the other set of guide seats 10 and the other set of arc-shaped limiting seats 11 to move inward in parallel along the guide rod 9. A slide rod 14 is fixedly installed inside the rail 3. A slide seat 15 is installed on the side wall of the slide rod 14. The slide seat 15 is slidably connected to the slide rod 14. The upper end of the upper toothed plate 6 is fixedly connected to the bottom wall of the slide seat 15. The upper toothed plate 6 can drive the slide seat 15 to move smoothly along the slide rod 14. A side plate 16 is fixedly installed on one side of the bottom wall of the mounting ring seat 1. A push-pull rod 17 is installed inside the side plate 16. The push-pull rod 17 is slidably connected to the side plate 16. One end of the push-pull rod 17 is fixedly connected to the side wall of a set of arc-shaped limiting seats 11. Pushing the push-pull rod 17 inward can push the set of arc-shaped limiting seats 11 to move inward in parallel.
[0026] Please see Figure 4 and Figure 6A fixing plate 18 is fixedly installed on the bottom wall of the side plate 16. A positioning rod 20 is installed inside the fixing plate 18 and is slidably connected to the fixing plate 18. Multiple positioning holes 19 are opened on the bottom wall of the other end of the push-pull rod 17. The upper end of the positioning rod 20 is engaged with the positioning hole 19. A limit ring 21 is fixedly installed on the lower side wall of the positioning rod 20. A return spring 22 is fixedly installed on the upper end of the limit ring 21. The upper end of the return spring 22 is fixedly connected to the bottom wall of the fixing plate 18. When the positioning rod 20 is released, under the elastic action of the return spring 22, the upper end of the positioning rod 20 is reinserted into the positioning hole 19, and the push-pull rod 17 and the two arc-shaped limit seats 11 on both sides are locked again. A limit edge 23 is fixedly installed on the side wall of the mounting cylinder 13. An annular protruding ring 24 is fixedly installed on the upper end of the limit edge 23. An mounting hole 25 is opened inside the mounting ring seat 1. The bottom of the mounting hole 25 is... An annular groove 26 is provided on the wall, and an annular protrusion 24 abuts against the annular groove 26, so that the limiting edge 23 of the mounting cylinder 13 and the annular protrusion 24 are tightly fitted with the annular groove 26 inside the mounting ring seat 1, ensuring the stability of the filter bag body 12 in the mounting ring seat 1. Two sets of limiting grooves 27 are provided on both sides of the bottom wall of the mounting ring seat 1. A protrusion 28 is fixedly provided on the inner wall of the limiting groove 27. Two sets of limiting blocks 29 are fixedly provided on both sides of the limiting edge 23. A limiting hole 30 is provided through the inside of the limiting block 29. The limiting block 29 is engaged with the protrusion 28 through the limiting hole 30. The inner walls of the arc-shaped limiting seats 11 on both sides abut against the sides of the mounting cylinder 13, so that the limiting blocks 29 on both sides are tightly fitted with the limiting grooves 27 on both sides. At the same time, the protrusions 28 on both sides are tightly engaged with the limiting holes 30 inside the limiting blocks 29 on both sides, further enhancing the firmness of the connection.
[0027] During the use of the blended filter bag, firstly, the limiting edge 23 and the annular protrusion 24 of the mounting cylinder 13 are tightly fitted with the annular groove 26 inside the mounting ring seat 1 to ensure the stability of the filter bag body 12 in the mounting ring seat 1. Then, the two side limiting blocks 29 are tightly fitted with the two side limiting grooves 27, and simultaneously, the two side protrusions 28 are tightly engaged with the limiting holes 30 inside the two side limiting blocks 29, further enhancing the connection's strength.
[0028] Then, pulling the positioning rod 20 downwards will disengage its upper end from the positioning hole 19. At this time, the push-pull rod 17 and the arc-shaped limiting seats 11 on both sides are locked, and the return spring 22 is stretched and deformed.
[0029] Next, push the push-pull rod 17 inward. The push-pull rod 17 can push a set of arc-shaped limiting seats 11 to move inward in parallel. The upper end of the set of arc-shaped limiting seats 11 can push a set of guide seats 10 and upper toothed plates 6 to move inward in parallel along the guide rod 9. Since the upper toothed plates 6 mesh with the upper side of the adjusting gear 5, the upper toothed plates 6 can drive the adjusting gear 5 to rotate. Since the lower side of the adjusting gear 5 meshes with the lower toothed plates 7, the adjusting gear 5 can drive the lower toothed plates 7 to move inward in parallel. The lower toothed plates 7 can then drive another set of guide seats 10 and another set of arc-shaped limiting seats 11 to move inward in parallel along the guide rod 9. This allows the two sets of arc-shaped limiting seats 11 to move in parallel towards the center until their inner walls are in close contact with the side walls of the upper end mounting cylinder 13 of the filter bag body 12. During this process, the upper toothed plates 6 can drive the slide 15 to move smoothly along the slide rod 14.
[0030] Finally, the positioning rod 20 is released. Under the elastic action of the return spring 22, the upper end of the positioning rod 20 is reinserted into the positioning hole 19. The push-pull rod 17 and the arc-shaped limiting seats 11 on both sides are locked again. At this time, the two sets of arc-shaped limiting seats 11 tightly hold the side wall of the mounting cylinder 13, ensuring the stable installation of the filter bag body 12 in the mounting ring seat 1. Throughout the process, the design of the adaptive adjustment limiting structure has achieved a stable installation effect on filter bag bodies 12 of different sizes.
[0031] Through the above steps, during the use of the blended filter bag, firstly, the upper end of the mounting cylinder 13 is tightly fitted with the lower end of the mounting ring seat 1. Then, a set of arc-shaped limiting seats 11 are pushed inward to move parallel. The upper end of the set of arc-shaped limiting seats 11 can push a set of guide seats 10 and the upper toothed plate 6 to move parallel inward along the guide rod 9. Since the upper toothed plate 6 meshes with the upper side of the adjusting gear 5, the upper toothed plate 6 can drive the adjusting gear 5 to rotate. Since the lower side of the adjusting gear 5 meshes with the lower toothed plate 7, the adjusting gear 5 can drive the lower toothed plate 7 to move parallel inward. The lower toothed plate 7 can move the other set of guide seats 10 and the other set of arc-shaped limiting seats 11 in parallel to the inside along the guide rod 9. This allows the two sets of arc-shaped limiting seats 11 to move in parallel to the center until their inner walls are in close contact with the side wall of the upper mounting cylinder 13 of the filter bag body 12. At this time, the two sets of arc-shaped limiting seats 11 tightly hold the side wall of the mounting cylinder 13, ensuring the stable installation of the filter bag body 12 in the mounting ring seat 1. Throughout the process, the design of the adaptive adjustment limiting structure can achieve flexible adjustment and stable installation of filter bags of different sizes.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
