Description

Technical Field

[0001] This utility model relates to the field of filter bag buckle technology, and in particular to a dust collector filter bag buckle anti-detachment mechanism. Background Technology

[0002] The filter bag clip anti-detachment mechanism in a dust collector serves the following main functions: During dust collector operation, airflow exerts impact and vibration on the filter bags. If the clips lack an anti-detachment mechanism, the filter bags may gradually loosen or even detach due to these external forces. The anti-detachment mechanism, through special designs such as increased clamping force and anti-slip structures, firmly secures the filter bags in their installation position, preventing displacement or detachment under normal operating conditions. Stable filter bag installation is crucial for ensuring dust collection efficiency. If the filter bags detach or loosen, dust-laden gas will leak, and unfiltered gas will be directly discharged, reducing dust collection effectiveness and affecting air quality.

[0003] However, existing technologies, such as Chinese Publication No. CN222518090U, "A Dust Collector Filter Bag Buckle Anti-Drop Mechanism," relate to the technical field of dust collector filter bags, and particularly to a dust collector filter bag buckle anti-drop mechanism. This mechanism includes a filter bag, with a housing fixedly connected to the upper surface of the filter bag. An anti-drop mechanism is provided on the upper surface of the housing. A frame is installed on the inner surface of the filter bag, and an adjustment mechanism is provided at one end of the frame. This dust collector filter bag buckle anti-drop mechanism, through the arrangement of a fixing plate, limiting groove, fixing block, locking groove, spring, and bolt, allows the filter bag to be installed by passing through the mounting opening of the housing. During downward installation, the filter bag passes the fixing block on the fixing plate, compressing the bolt and spring, causing the bolt to retract into the locking groove. When the bolt passes through the limiting groove on the filter bag, it pops out and engages in the limiting groove, thereby fixing the filter bag and preventing it from falling off, thus improving the dust collector's dust removal efficiency.

[0004] However, this device lacks a self-locking clamping mechanism, meaning it cannot provide reliable and continuous clamping force after the filter bag is installed through its own locking function. This makes it impossible to ensure a tight connection between the filter bag and the tube sheet or frame, causing the filter bag to loosen or fall off during dust collector operation due to external forces such as airflow impact and vibration. Furthermore, the device lacks a multiple fixing structure, and a single fixing method may not provide sufficient stability in certain situations. It cannot distribute these forces to different fixing points and components, leading to excessive local stress on the filter bag and causing damage. Utility Model Content

[0005] The purpose of this invention is to address the problems in the existing technology where, after the filter bag is installed, its own locking function cannot provide a reliable and continuous clamping force, thus failing to ensure a tight connection between the filter bag and the tube sheet or frame. This results in the filter bag loosening or falling off during dust collector operation due to external forces such as airflow impact and vibration. Furthermore, a single fixing method may not provide sufficient stability in certain situations, failing to distribute these forces to different fixing points and components, leading to excessive local stress on the filter bag and subsequent damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust collector filter bag buckle anti-detachment mechanism, comprising an installation plate, a connecting pipe connected to the top of the installation plate, a main housing fixedly connected to the top of the installation plate, a plurality of shafts fixedly connected to the inner surface of the main housing, a clamping rod rotatably connected to the outer surface of the shafts, a rod sleeve movably sleeved on the outer surface of the clamping rod, a rotating ring rotatably connected to the outer surface of the plurality of rod sleeves, a plurality of worm teeth fixedly connected to the outer surface of the rotating ring, and a worm gear meshing with the outer surface of the plurality of worm teeth, which, under the meshing action of the worm gear and the worm teeth, will drive the rotating ring to rotate.

[0007] In a preferred embodiment, the outer surface of the worm gear is rotatably connected to two shaft blocks and extends out at one end. One side of the two shaft blocks is fixedly connected to the inner surface of the main housing, and the worm gear can rotate inside the shaft blocks and inside the main housing.

[0008] In a preferred embodiment, the outer surface of the worm gear is rotatably connected to the inside of the main housing and extends out at one end. A knob is fixedly connected to the extended end of the worm gear, and the knob drives the worm gear to rotate inside the shaft block and inside the main housing.

[0009] In a preferred embodiment, a fixing block is fixedly connected to the top of the main housing, and a limiting groove is formed on both sides of the inner surface of the fixing block, so that the limiting plate can only move in the opposite direction of the limiting groove.

[0010] In a preferred embodiment, two limiting plates are movably embedded in the inner surfaces of the two limiting grooves, and a clamping plate is fixedly connected to one side of each limiting plate. The two limiting plates and the clamping plate approach each other inside the fixing block along the slotting direction of the limiting grooves to fix the filter bag again.

[0011] In a preferred embodiment, a connecting plate is fixedly connected to the side of the limiting plate away from the clamping plate, and a through groove is opened on one side of the fixing block. The outer surfaces of the two connecting plates are disposed inside the through groove, and the connecting plates can move inside the through groove.

[0012] In a preferred embodiment, the end of the connecting plate away from the limiting plate is fixedly connected to an internal threaded sleeve, and the inner surfaces of the two internal threaded sleeves are threadedly connected to positive and negative threaded rods. One end of the positive and negative threaded rods is fixedly connected to a rocker arm, so rotating the threads will drive the connecting plate to move inside the through groove.

[0013] In a preferred embodiment, the outer surface of the positive and negative lead screw is rotatably connected to two shaft plates, one side of which is fixedly connected to the outer surface of the fixing block, and the positive and negative lead screw is driven to rotate inside the shaft plates by a rocker arm.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model has a self-locking clamping mechanism, which can provide a reliable and continuous clamping force after the filter bag is installed through its own locking function, so as to ensure a tight connection between the filter bag and the tube sheet or frame, and prevent the filter bag from loosening or falling off due to external forces such as airflow impact and vibration during the operation of the dust collector.

[0016] 2. The present invention has a device with multiple fixing structures to avoid the possibility that a single fixing method may not be able to provide sufficient stability in some situations. It can distribute these forces to different fixing points and fixing components, and avoid excessive local stress on the filter bag, which may lead to damage. Attached Figure Description

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a dust collector filter bag buckle anti-drop mechanism, including a mounting plate 1, a connecting pipe 2 connected to the top of the mounting plate 1, a main housing 3 fixedly connected to the top of the mounting plate 1, a plurality of shafts 4 fixedly connected to the inner surface of the main housing 3, a clamping rod 5 rotatably connected to the outer surface of the shafts 4, a rod sleeve 6 movably sleeved on the outer surface of the clamping rod 5, a rotating ring 7 rotatably connected to the outer surface of the multiple rod sleeves 6, a plurality of worm teeth 8 fixedly connected to the outer surface of the rotating ring 7, and a worm 9 meshing with the outer surface of the multiple worm teeth 8, driving the internal rod sleeves 6, so that the clamping rod 5 swings about the shafts 4 as the axis, and initially clamps and fixes the internal filter bag.

[0026] like Figures 1 to 5 As shown, the outer surface of the worm gear 9 is rotatably connected to two shaft blocks 10 and extends out one end. One side of the two shaft blocks 10 is fixedly connected to the inner surface of the main housing 3. The worm gear 9 can rotate inside the shaft blocks 10 and inside the main housing 3.

[0027] like Figures 1 to 5 As shown, the outer surface of the worm gear 9 is rotatably connected to the inside of the main housing 3 and extends out at one end. A knob 11 is fixedly connected to the extended end of the worm gear 9. The knob 11 drives the worm gear 9 to rotate inside the shaft block 10 and inside the main housing 3.

[0028] like Figures 1 to 5 As shown, a fixing block 12 is fixedly connected to the top of the main unit housing 3. Limiting grooves 13 are opened on both sides of the inner surface of the fixing block 12. The limiting plate 14 can only move in the opposite direction of the opening of the limiting groove 13.

[0029] like Figures 1 to 5As shown, two limiting plates 14 are movably embedded in the inner surface of the two limiting grooves 13. A clamping plate 15 is fixedly connected to one side of the limiting plate 14. The two limiting plates 14 and the clamping plate 15 approach each other inside the fixing block 12 along the slotting direction of the limiting grooves 13 to fix the filter bag again.

[0030] like Figures 1 to 5 As shown, a connecting plate 16 is fixedly connected to the side of the limiting plate 14 away from the clamping plate 15. A through groove 17 is provided on one side of the fixing block 12.

[0031] like Figures 1 to 5 As shown, the end of the connecting plate 16 away from the limiting plate 14 is fixedly connected to an internal threaded sleeve 18. The inner surfaces of the two internal threaded sleeves 18 are threadedly connected to positive and negative threaded rods 19. One end of the positive and negative threaded rods 19 is fixedly connected to a rocker arm 20. Therefore, rotating the threads will cause the connecting plate 16 to move inside the through groove 17.

[0033] Working principle: First, the filter bag is fitted onto one side of the mounting plate 1 and the outer surface of the connecting pipe 2. Then, the worm gear 9 is rotated inside the shaft block 10 and the main housing 3 by the knob 11. Under the meshing action of the worm gear 9 and the worm teeth 8, the rotating ring 7 will rotate, and the internal rod sleeve 6 will be driven, so that the clamping rod 5 swings around the shaft 4 as the axis, and the filter bag inside is initially clamped and fixed. Then, the rocker arm 20 drives the positive and negative screw 19 to rotate inside the shaft plate 21. The rotating screw will drive the internal thread sleeve 18. The limiting plate 14 can only move in the opposite direction of the slot of the limiting groove 13. Therefore, the rotating screw will drive the connecting plate 16 to move inside the through groove 17. At the same time, the two limiting plates 14 and the clamping plate 15 move closer to each other inside the fixing block 12 along the slot direction of the limiting groove 13, and fix the filter bag again.
