Description

Technical Field

[0001] The present invention relates to the technical field of hanging conveyor racks, and specifically to a hanging conveyor rack for environmental protection filter bag processing. Background Art

[0002] An environmental protection filter bag is a filtering device made of synthetic fibers (such as PPS, PTFE, polyimide, etc.) or natural fibers as the base material through precise weaving or gradient needle punching processes. Its surface is densely covered with micron-sized pores (as small as 3μm), which can intercept 99.5%-99.99% of dust particles while maintaining air permeability, and is widely used in high-temperature and corrosive gas purification scenarios.

[0003] A Chinese patent with an application date of November 2, 2023 and an application number of CN202311447300.X discloses a hanging rack for environmental protection filter bag processing, belonging to the field of filter bags, including a cross-shaped support plate. Both the front side and the rear side of the upper end surface of the cross-shaped support plate are fixedly installed with support frames. A first fixing mechanism is arranged inside the support frames. A width adjustment mechanism is arranged above the cross-shaped support plate. A driving adjustment mechanism is arranged inside the width adjustment mechanism. A second fixing mechanism is arranged below the cross-shaped support plate. The first fixing mechanism includes a rotating shaft one rotatably connected to the lower side inside the support frame, and a lower driving wheel fixedly installed on the outer surface of the rotating shaft one. In this solution, by setting the width adjustment mechanism, the motor one rotates in reverse, and under the action of the one-way bearing, the reciprocating lead screw is driven to rotate, and the push plate is displaced by cooperating with the first thread sleeve, the second thread sleeve, the first connecting rod and the second connecting rod, so that the pick-up rod extends outwards on both sides, extending the length of the pick-up rod, enabling the device to adaptively adjust to pick-up rods of different widths, and relatively improving the practicality of the device.

[0004] However, during the hanging and conveying process of the environmental protection filter bag, the shape of the guide rail is circular. There are two connection points between the hanging rack in this technical solution and the guide rail. When passing through the turning point of the guide rail, it is easy to affect the smoothness of the environmental protection filter bag during the conveying process, so further improvement can be made.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a hanging conveyor rack for processing environmentally friendly filter bags, which has the following beneficial effects:

[0020] 1. For the hanging conveyor rack for processing environmentally friendly filter bags, the vertical rod passes through the annular mounting groove, the rollers roll on the bottom walls of the linear guide rail and the semi-circular guide rail, and the contact points between the hooks and the annular guide are few, which can ensure the smooth movement of the hooks. Therefore, after the environmentally friendly filter bag is hung on the hanging component and then the hanging component is hung on the hook, it is not easy to get stuck during the transportation of the environmentally friendly filter bag, ensuring the smoothness of the transportation;

[0021] 2. For the hanging conveyor rack for processing environmentally friendly filter bags, the annular guide bears the weights of the hooks, the hanging components and the environmentally friendly filter bags. Thus, the chain will not be subjected to a large pulling force in the vertical direction, which can reduce the friction during the movement of the chain, ensure the service life of the chain, reduce the number of shutdowns for maintenance due to chain damage, ensure the reliability of the environmentally friendly filter bag transportation, and ensure the production efficiency of the environmentally friendly filter bags;

[0022] 3. For the hanging conveyor rack for processing environmentally friendly filter bags, the environmentally friendly filter bag is folded once, and the folded part of the environmentally friendly filter bag is attached to the upper surface of the cross bar. The two ends of the environmentally friendly filter bag naturally hang down. Under the action of the weight of the environmentally friendly filter bag, the cross bar and the sliding seat move downward, driving the arched frame and the rack plate to move downward, thereby driving the gear to rotate, and then causing the U-shaped cantilever to deflect. The two clamping rods first move towards the middle of the vertical plate and then cross the middle of the vertical plate, so that two bends are formed under the cross bar of the environmentally friendly filter bag, and the environmentally friendly filter bag is stably placed on the cross bar; thus achieving the purpose of stably placing the environmentally friendly filter bag and not easily falling off;

[0023] 4. For the hanging conveyor rack for processing environmentally friendly filter bags, the connecting ring passes through the avoidance opening and enters the inside of the hanging ring, and the connecting ring is clamped between the two partition plates at the rightmost end of the arc-shaped slide bar, driving the arc-shaped slide bar to slide clockwise along the arc-shaped chute until the connecting ring moves to the lowest point of the inner arc surface of the hanging ring, and the arc-shaped slide bar blocks the avoidance opening, so that the hanging ring and the arc-shaped slide bar form an annular structure, and the connecting ring is stably connected inside the hanging ring; thus achieving the purpose of stable and reliable connection between the hanging component and the hook.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figure 1 , a hanging conveyor for environmental protection filter bag processing, including an annular guiding member 200, anchor rods 100 are fixedly arranged in an array at the top of the annular guiding member 200, a plurality of hooks 300 are slidably connected to the bottom of the annular guiding member 200, a bracket 400 is arranged below the middle of the annular guiding member 200, an annular moving driving member 500 is arranged at the top of the bracket 400, a tensioning assembly 600 is arranged in the middle of the annular moving driving member 500, push rods 700 are fixedly arranged at equal intervals at the top of the annular moving driving member 500, the push rods 700 correspond to the hooks 300 one by one, the hooks 300 are slidably connected to the push rods 700, and a hanging assembly 800 is hung at the bottom of the hooks 300.

[0044] Please refer to Figure 2, the annular guide member 200 includes an annular top plate 201. The anchor rod 100 is welded to the top of the annular top plate 201, and the top end of the anchor rod 100 is fixed to the ceiling of the workshop, thereby suspending the annular top plate 201. Two linear guide rails 202 are fixedly installed at the bottom of the annular top plate 201. The two linear guide rails 202 are distributed front and back. A semi-circular guide rail 203 is fixedly installed between the ends of the two linear guide rails 202. The two linear guide rails 202 and the two semi-circular guide rails 203 form an annular track. The cross-sections of the linear guide rail 202 and the semi-circular guide rail 203 are both U-shaped. The linear guide rail 202 seals the top openings of the linear guide rail 202 and the semi-circular guide rail 203. An annular installation groove 204 is formed through the bottom of the linear guide rail 202 and the semi-circular guide rail 203. The annular installation groove 204 divides the annular track into an inner part and an outer part. The annular top plate 201 fixes the two parts of the annular track together. The hook 300 passes through the annular installation groove 204 and is slidably connected to the linear guide rail 202 and the semi-circular guide rail 203. Thus, the hook 300 is suspended below the annular track and can move along the annular track. By bearing the weights of the hook 300, the hanging assembly 800, and the environmental protection filter bag through the annular track, the annular movement driving member 500 will not be subjected to excessive tensile force in the vertical direction, ensuring the service life of the annular movement driving member 500.

[0045] Please refer to Figures 5 - 8 , the hook 300 includes a vertical rod 301. The vertical rod 301 passes through the annular installation groove 204. A hanging ring 302 is fixedly installed at the bottom end of the vertical rod 301. An avoidance opening 303 is formed through the side of the hanging ring 302. Fixed shafts 304 are fixedly installed on both sides of the top end of the vertical rod 301. Rollers 305 are rotatably connected to the fixed shafts 304. The rollers 305 roll on the bottom walls of the linear guide rail 202 and the semi-circular guide rail 203. An insertion hole 306 is formed through the vertical rod 301. The push rod 700 passes through the insertion hole 306. Thus, the push rod 700 is driven to move along an annular path by the annular movement driving member 500, and the vertical rod 301 is driven to move along the annular installation groove 204 by the push rod 700.

[0046] An arc-shaped chute 307 is provided inside the hanging ring 302. A fixing plate 308 is fixedly installed on the inner wall of the arc-shaped chute 307. The fixing plate 308 is located in the upper half of the hanging ring 302 on the side away from the avoidance opening 303. An arc-shaped sliding bar 309 is slidably connected in the arc-shaped chute 307. A tension spring 310 is fixedly installed between one end of the arc-shaped sliding bar 309 away from the avoidance opening 303 and the fixing plate 308. Due to the pulling force of the tension spring 310, the arc-shaped sliding bar 309 has a tendency to slide upward and to the right along the arc-shaped chute 307, exposing the avoidance opening 303, facilitating the hanging component 800 to pass through the avoidance opening 303 and hang on the hanging ring 302. Partition plates 311 are fixedly arranged in an array on the inner arc surface of the arc-shaped sliding bar 309. The partition plates 311 are used to limit the hanging component 800, preventing the hanging component 800 from moving too large a distance relative to the arc-shaped sliding bar 309 after being hung on the hanging ring 302.

[0047] One end of the arc-shaped sliding bar 309 away from the avoidance opening 303 is fixedly installed with an arc-shaped baffle 312, and the arc-shaped baffle 312 slides within the opening of the arc-shaped chute 307. The tension spring 310 is covered by the arc-shaped baffle 312. After the hanging component 800 passes through the avoidance opening 303 and enters the hanging ring 302, the hanging component 800 is hung between two partition plates 311 at the rightmost end of the arc-shaped sliding bar 309. Under the pulling of the weight of the hanging component 800 and the environmental protection filter bag, the arc-shaped sliding bar 309 slides clockwise along the arc-shaped chute 307, moving the hanging component 800 to the lowest point of the inner arc surface of the hanging ring 302, so that the arc-shaped sliding bar 309 blocks the avoidance opening 303, and thus the hanging ring 302 and the arc-shaped sliding bar 309 form an annular structure to limit the hanging component 800.

[0048] Please refer to Figure 2 , the bracket 400 includes a support plate 401 arranged below the middle of the annular top plate 201. There is a gap between the support plate 401 and the annular track for the push rod 700 to pass through. A fixing rod 402 is fixedly installed on the top of the support plate 401. Bearing plates 403 are placed on the tops of both ends of the annular top plate 201. Through holes 404 are penetrated through the bearing plates 403, and the anchor rod 100 passes through the through holes 404. The fixing rod 402 is fixedly installed at the bottom of the bearing plate 403, so that the support plate 401 is suspended below the bearing plate 403 through the fixing rod 402, and the annular top plate 201 bears the bearing plate 403. An upward-extending annular flange 405 is welded to the edge of the support plate 401. Since it is necessary to lubricate the annular moving drive member 500 to ensure the service life of the annular moving drive member 500, through the arrangement of the annular flange 405, it is prevented that the lubricating oil on the top of the support plate 401 drips directly downward, a certain amount of lubricating oil can be accumulated, and the lubricating oil on the top of the support plate 401 can be cleaned regularly. Similarly, upward flanges can also be provided on the two side walls of the annular installation groove 204.

[0049] Please refer toFigures 3 - 4 The annular moving drive member 500 includes two sprockets 501 which are respectively rotatably connected to the tops of both ends of the pallet 401. The two sprockets 501 are connected by a chain 502. A speed reducer 503 is fixedly installed on the top of one of the bearing plates 403. The output end of the speed reducer 503 is fixedly installed with the sprocket 501, and the input end of the speed reducer 503 is fixedly installed with a first motor 504. The push rod 700 is fixedly installed on the top of the chain 502 and is fixed to the outer link plate of the chain 502.

[0050] Please refer to Figures 3 - 4 The tensioning assembly 600 includes two supports 601 fixedly installed on the top of the pallet 401. The two supports 601 are distributed left and right. Two slide bars 602 are fixedly installed between the two supports 601. A threaded rod 603 is rotatably connected between the two slide bars 602. The thread directions of the left half and the right half of the threaded rod 603 are opposite. A second motor 604 is fixedly installed at the right end of the threaded rod 603. Two sliders 605 are slidably connected to the slide bars 602. The two sliders 605 are respectively threadedly connected to the left half and the right half of the threaded rod 603. Thus, when the second motor 604 drives the threaded rod 603 to rotate, the two sliders 605 are driven to move towards each other or away from each other along the slide bars 602. Two connecting plates 606 are hinged to the bottoms of both of the two sliders 605. The four connecting plates 606 are distributed in a parallelogram shape, and two of the corners are hinged to the bottoms of the two sliders 605, and two pressing wheels 607 are hinged at the other two corners. The two pressing wheels 607 are attached to the inner side of the chain 502. When the two sliders 605 move towards each other, through the connection of the connecting plates 606, the two pressing wheels 607 are driven to move away from each other. The two pressing wheels 607 are attached to the middle of the chain 502 and push the middle of the chain 502 outwards to tighten the chain 502. Since the shape of the chain 502 changes after being tightened, the push rod 700 slides relative to the vertical rod 301 to compensate for the deformation of the chain 502.

[0051] Please refer to Figure 6 and Figures 9 - 10, the hanging component 800 includes a horizontal plate 801, a vertical plate 802 is fixedly installed at the left end of the horizontal plate 801, and the horizontal plate 801 and the vertical plate 802 are perpendicular to each other. A connecting ring 803 is fixedly installed at the top of the horizontal plate 801. The connecting ring 803 passes through the avoidance opening 303 and is hung on the hanging ring 302. The width of the avoidance opening 303 is greater than the diameter of the connecting ring 803. A guiding groove 804 is penetrated and opened on the vertical plate 802, a sliding seat 805 is slidably connected in the guiding groove 804, a cross bar 806 is fixedly installed on the right side of the sliding seat 805. The cross bars 806 are distributed in a conical shape, and the diameter gradually increases from left to right. A limiting ring 807 is fixedly installed at the left end of the cross bar 806. When placing the environmental protection filter bag, fold the environmental protection filter bag once and then place it on the cross bar 806. The cross bar 806 fits at the folding part of the environmental protection filter bag, and the environmental protection filter bag hangs down from both sides of the cross bar 806. Thus, the environmental protection filter bag has a tendency to move to the left, and the limiting ring 807 blocks and limits the environmental protection filter bag to prevent the environmental protection filter bag from falling off from the free end of the cross bar 806 during transportation.

[0052] Two clamping rods 808 are arranged below the cross bar 806. The two clamping rods 808 are distributed front and back and the heights of the two clamping rods 808 are different. A transmission member 809 is arranged between the sliding seat 805 and the left ends of the two clamping rods 808. When the environmental protection filter bag is placed on the top of the cross bar 806, under the action of the weight of the environmental protection filter bag, the cross bar 806 and the sliding seat 805 move downward. With the transmission action of the transmission member 809, the two clamping rods 808 first move towards the middle of the vertical plate 802, and then cross the middle of the vertical plate 802, so that the two clamping rods 808 are staggered from each other. Then, with the bearing action of the cross bar 806 on the environmental protection filter bag, the two clamping rods 808 push the environmental protection filter bag to bend, so that the environmental protection filter bag is stably placed on the cross bar 806.

[0053] Please refer to Figures 9 - 10 , the transmission member 809 includes two U-shaped cantilevers. The two U-shaped cantilevers are respectively located on the front and back sides of the vertical plate 802, and the two U-shaped cantilevers are respectively fixedly installed with the left ends of the two clamping rods 808. Each U-shaped cantilever includes a rotating arm 8091 rotatably connected to the left side of the vertical plate 802. A supporting arm 8092 is welded at the bottom end of the rotating arm 8091. An extending arm 8093 is welded at the right end of the supporting arm 8092. The extending arm 8093 and the supporting arm 8092 are distributed in an L shape. The rotating arm 8091 is initially inclined downward, and the supporting arm 8092 and the extending arm 8093 are horizontal. The end of the extending arm 8093 away from the supporting arm 8092 is fixedly installed with the clamping rod 808.

[0054] A gear 8094 is fixedly installed at the upper end of the swing arm 8091. The transmission member 809 further includes an arch-shaped frame 8095 fixedly installed on the left side of the slide seat 805. The lengths of both sides of the arch-shaped frame 8095 are unequal. Rack plates 8096 are fixedly installed on both inner side walls of the arch-shaped frame 8095. The rack plates 8096 are engaged with the gear 8094. A guide rod 8097 is fixedly installed at the bottom left of the vertical plate 802. The slide seat 805 is slidably connected to the guide rod 8097. A spring 8098 is fixedly installed between the bottom end of the guide rod 8097 and the bottom of the slide seat 805. Thus, after the environmental protection filter bag is placed on the surface of the cross bar 806, under the action of the weight of the environmental protection filter bag, the cross bar 806 and the slide seat 805 move downward, which will drive the arch-shaped frame 8095 and the rack plates 8096 to move downward, thereby driving the gear 8094 to rotate, and further deflecting the U-shaped cantilever. The two clamping rods 808 squeeze the environmental protection filter bag, so that the environmental protection filter bag is stably placed on the cross bar 806.

[0055] During use, first, fold the environmental protection filter bag once, and attach the folded part of the environmental protection filter bag to the upper surface of the cross bar 806. The two ends of the environmental protection filter bag hang down naturally. Under the action of the weight of the environmental protection filter bag, the cross bar 806 and the slide seat 805 move downward, which will drive the arch-shaped frame 8095 and the rack plates 8096 to move downward, thereby driving the gear 8094 to rotate, and further deflecting the U-shaped cantilever. The two clamping rods 808 first move towards the middle of the vertical plate 802, and then cross the middle of the vertical plate 802, so that the environmental protection filter bag forms two bends under the cross bar 806, and the environmental protection filter bag is stably placed on the cross bar 806.

[0056] Then, pass the connecting ring 803 through the avoidance opening 303 and into the interior of the hanging ring 302, and snap the connecting ring 803 between the two partition plates 311 at the rightmost end of the arc-shaped slide bar 309, driving the arc-shaped slide bar 309 to slide clockwise along the arc-shaped chute 307 until the connecting ring 803 moves to the lowest point of the inner arc surface of the hanging ring 302. The arc-shaped slide bar 309 blocks the avoidance opening 303, so that the hanging ring 302 and the arc-shaped slide bar 309 form an annular structure, and the connecting ring 803 is stably connected inside the hanging ring 302.

[0057] Drive one of the sprockets 501 to rotate through the motor one 504 and the reducer 503, thereby driving the chain 502 to move; during the process of the push rod 700 following the movement of the chain 502, the vertical rod 301 is pushed to slide along the annular installation groove 204, so that the environmental protection filter bag moves along the annular track.

[0058] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
