Abstract
Description
Technical Field
[0001] This invention relates to the field of overhead conveying technology, and more specifically to an overhead conveying device for metal profile processing. Background Technology
[0002] Overhead conveyor systems are a common means of supplying and transporting parts in mechanical assembly lines or painting lines. This equipment uses a chain drive structure to hang the workpieces, enabling continuous transport. The hangers move with the conveyor chain. Overhead conveyor systems are especially indispensable in the processing of metal profiles.
[0003] Existing overhead conveyor equipment requires shutdown to remove the hangers for cleaning. In order to ensure the effectiveness of the hangers, the frequency of shutdown for cleaning needs to be increased, which affects the overall processing efficiency of metal profiles. Therefore, it is difficult to clean the hangers in a timely manner after each use. The hangers are prone to accumulating powder or solidified layers, which affects their conductive contact with the metal profiles, resulting in a low powder application rate of the metal profiles and affecting the processing quality of the metal profiles. Summary of the Invention
[0004] The purpose of this invention is to provide a suspended conveying device for metal profile processing to overcome the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a suspended conveying device for metal profile processing, comprising a track and multiple suspensions mounted on the track, and further comprising:
[0006] The cover is installed at the bottom of the suspension, and two hangers are installed at the bottom of the cover;
[0007] The recycling mechanism includes a lifting bar installed inside the enclosure, springs fixed to both ends of the lifting bar, a sealing block fixed to the bottom of the springs, and a transmission assembly for driving the lifting bar to rise and fall. The top of the hanger is fixed to the bottom of the sealing block.
[0008] The linkage maintenance mechanism has two parts. The linkage maintenance mechanism includes a scraper located below the lifting bar, a scraper groove opened inside the scraper, and an adjustment component for driving the scraper to move after the hanger moves up. The inner wall of the scraper groove is adapted to the outer wall of the hanger.
[0009] Furthermore, the transmission assembly includes a transmission shaft rotatably connected inside the housing, a reciprocating screw fixedly sleeved outside the transmission shaft, and a first gear fixedly connected to the top of the transmission shaft.
[0010] The lifting bar is threaded to the outside of the reciprocating screw, and two first guide rods are fixed inside the cover. The lifting bar is also slidably sleeved on the outside of the first guide rods.
[0011] The top of the drive shaft extends to the outside of the cover.
[0012] Furthermore, a first rack and a second rack are sequentially fixed to the bottom of the track along the direction of movement of the hanger, and the first gear engages with the first rack and the second rack in sequence when it moves to the position.
[0013] Furthermore, the bottom of the cover has two adapter slots, the hanger is installed through the adapter slots, and the width of the adapter slots is the same as the width of the hanger. The outer diameter of the sealing block is larger than the outer diameter of the adapter slots and abuts against the top of the adapter slots.
[0014] Furthermore, the adjustment assembly includes a fixed seat fixed to the inner wall of the bottom of the cover, a lead screw rotatably connected to the outer wall of the fixed seat near the scraper, and a drive component for driving the lead screw to rotate.
[0015] The lead screw is externally threaded to a slider, and multiple linkage rods are fixedly connected to the outer wall of one side of the slider. The other end of the linkage rod is fixedly connected to the outer wall of the scraper.
[0016] Furthermore, the driving component includes a light strip fixed to the bottom of the lifting bar, a third rack fixed to the bottom of the light strip, and a second gear fixedly sleeved on the outside of the lead screw;
[0017] The lifting bar moves the third rack upwards via the light bar until it reaches the height of the second gear, at which point it meshes with the second gear.
[0018] Furthermore, the bottom of the cover is provided with two through slots, through which the light strip passes, and a sealing shell is installed at the bottom of the through slot. The through slot is connected to the sealing shell, and the third toothed rack is located inside the sealing shell.
[0019] Furthermore, a second guide rod is fixedly connected to the outer wall of one side of the fixed base, and the scraper is slidably sleeved on the outside of the second guide rod.
[0020] Furthermore, limit blocks are fixed to the inner walls on both sides of the cover. The limit blocks are used to block the sealing blocks. Limit grooves are formed inside the limit blocks for the passage of lifting bars.
[0021] Compared with the prior art, the suspended conveying equipment for metal profile processing provided by the present invention has the following advantages:
[0022] 1. After use, as the hanger moves along the track path, it is driven to move upward along the inner wall of the adapter groove. The adapter groove removes the powder or cured layer on both sides of the outer wall of the hanger. Then, the scraper is driven to remove the powder or cured layer on the inner and outer walls of the hanger. This achieves the effect of timely cleaning of the hanger and avoids the problem of powder or cured layer accumulating on the hanger affecting its conductive contact with the metal profile. At the same time, it avoids the problem of residual powder from the previous use falling off and contaminating the subsequent metal profile.
[0023] 2. By automatically cleaning the hangers, the problem of having to stop the machine and remove the hangers for cleaning in the prior art is solved, which improves the efficiency of the suspended conveyor equipment. This invention does not use power equipment, thus avoiding the problem that power equipment is easily damaged by high temperature when it enters the curing chamber. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0035] Example: Please refer to Figures 1-7 A suspended conveying device for metal profile processing includes a track 1 and multiple suspensions 2 mounted on the track 1, wherein the suspensions 2 are driven by sprockets to move along the path of the track 1; and further includes:
[0036] The cover 3 is installed at the bottom of the suspension 2, and two hangers 4 are installed at the bottom of the cover 3;
[0037] The recovery mechanism includes a lifting bar 5 disposed inside the cover 3, springs 6 fixed to both ends of the lifting bar 5, a sealing block 7 fixed to the bottom end of the springs 6, and a transmission assembly for driving the lifting bar 5 to rise and fall. The top end of the hanger 4 is fixed to the bottom of the sealing block 7. The transmission assembly includes a drive shaft 10 rotatably connected inside the cover 3, a reciprocating screw 11 fixedly sleeved outside the drive shaft 10, and a first gear 12 fixed to the top end of the drive shaft 10. The lifting bar 5 is threaded to the outside of the reciprocating screw 11. Two first guide rods are also fixed inside the cover 3. 25. The lifting bar 5 is also slidably sleeved on the outside of the first guide rod 25; the top end of the transmission shaft 10 extends to the outside of the cover 3; the bottom of the track 1 is sequentially fixed with the first rack 13 and the second rack 14 along the moving direction of the hanger 4; the first gear 12 moves to mesh with the first rack 13 and the second rack 14 in sequence; the bottom of the cover 3 has two adapter grooves 15; the hanger 4 is set through the adapter grooves 15; the width of the adapter grooves 15 is the same as the width of the hanger 4; the outer diameter of the sealing block 7 is larger than the outer diameter of the adapter grooves 15; and it abuts against the top of the adapter grooves 15.
[0038] The first rack 13 and the second rack 14 are located outside the metal profile powder spraying chamber. That is to say, after the cover 3 and the bottom hanger 4 pass the first rack 13 and the second rack 14, the workers hang the metal profile on the hanger 4 and then enter the powder spraying chamber and the curing chamber. The outside of the hanger 4 can be coated with graphene, which is both non-stick and does not affect the conductivity, and makes it easy to remove the curing layer on the outside of the hanger 4.
[0039] The suspension 2 drives the cover 3 to move along the track 1. When the first gear 12 meshes with the first rack 13, it drives the transmission shaft 10 to rotate, and the reciprocating screw 11 rotates synchronously. During the entire meshing process of the first gear 12 and the first rack 13, the lifting bar 5 is driven to move from the bottom end of the reciprocating screw 11 to its top end. When the lifting bar 5 moves upward, the spring 6 and the sealing block 7 drive the hanger 4 to move upward along the inner wall of the adapter groove 15. The adapter groove 15 removes the powder or solidified layer on both sides of the outer wall of the hanger 4 until the hanger 4 is completely inside the set position of the cover 3.
[0040] When the first gear 12 moves to mesh with the second rack 14, it drives the transmission shaft 10 and the reciprocating screw 11 to continue rotating. During the entire meshing process of the first gear 12 and the second rack 14, the lifting bar 5 moves from the top of the moving reciprocating screw 11 to its bottom, thereby driving the hanger 4 to move down and reset through the spring 6 and the sealing block 7. The sealing block 7 abuts against the inner wall of the bottom of the cover 3 to achieve rigid support for the hanger 4.
[0041] The linkage maintenance mechanism has two components. Each linkage maintenance mechanism includes a scraper 8 positioned below the lifting bar 5, a scraper groove 9 inside the scraper 8, and an adjustment component for driving the scraper 8 to move after the hanger 4 moves upwards. The inner wall of the scraper groove 9 is adapted to the outer wall of the hanger 4. The adjustment component includes a fixed base 16 fixed to the inner wall of the bottom of the cover 3, a lead screw 17 rotatably connected to the outer wall of the fixed base 16 near the scraper 8, and a drive component for driving the lead screw 17 to rotate. A slider 18 is threaded onto the outside of the lead screw 17. Multiple linkage rods 19 are fixed to the outer wall of one side of the slider 18, and the other end of the linkage rods 19 is fixed to the outer wall of the scraper 8. The drive component includes a light strip 20 fixed to the bottom of the lifting bar 5, a third rack 21 fixed to the bottom of the light strip 20, and a second gear 22 fixedly sleeved on the outside of the lead screw 17. When the lifting bar 5 moves upwards through the light strip 20, driving the third rack 21 to the height of the second gear 22, it... The second gear 22 is engaged. Two through slots 23 are also provided at the bottom of the cover 3. The light strip 20 is set through the through slots 23, and a sealing shell 24 is installed at the bottom of the through slots 23. The through slots 23 and the sealing shell 24 are connected. The third rack 21 is located inside the sealing shell 24. A second guide rod 28 is fixedly connected to the outer wall of one side of the fixed seat 16. The scraper 8 is slidably sleeved on the outside of the second guide rod 28. Limit blocks 26 are fixedly connected to the inner walls on both sides of the cover 3. The limit blocks 26 are used to block the sealing block 7. A limit groove 27 is opened inside the limit block 26. The limit groove 27 is used to pass through the lifting strip 5. A support rod 29 is fixedly connected to the top of the sealing block 7. The support rod 29 is slidably set through the lifting strip 5. The spring 6 is sleeved on the outside of the support rod 29. A through slot for the support rod 29 to pass through is opened at the top of the cover 3. The support rod 29 is set to avoid the problem of the hanging 4 tilting when the scraper 8 cleans the outside of the hanging 4.
[0042] As the hanger 4 moves upward along the inner wall of the adapter groove 15 via the spring 6 and sealing block 7, the sealing block 7 and hanger 4 stop moving upward when they abut against the bottom of the limiting block 26. At this point, the hanger 4 reaches the set position, which is at the same horizontal line as the scraper groove 9, ensuring that the scraper groove 9 can move to the outside of the hanger 4. Simultaneously, the lifting bar 5 moves upward, driving the light bar 20 and the third rack 21 to move upward synchronously. As the hanger 4 reaches the set position, the third rack 21 begins to mesh with the second gear 22. With the lifting bar 5 continuing to move upward... When the spring 6 is stretched, the third rack 21 drives the second gear 22 to rotate, and the lead screw 17 rotates accordingly, causing the slider 18 to move along the outer wall of the second guide rod 28 toward the hanger 4. The linkage rod 19 drives the scraper 8 to move synchronously. When the scraper groove 9 comes into contact with the inner and outer walls of the hanger 4, the powder or solidified layer on the inner and outer walls of the hanger 4 is removed, achieving the effect of timely cleaning of the hanger 4. This avoids the problem of powder or solidified layer accumulating on the hanger 4 affecting its conductive contact with the metal profile, and also avoids the problem of residual powder from the previous time falling off and contaminating the subsequent metal profile.
[0043] As the lifting bar 5 moves downward, the spring 6 contracts accordingly. Through the meshing of the third rack 21 and the second gear 22, the lead screw 17 rotates in the opposite direction, which in turn drives the slider 18 to move away from the hanger 4. Then, through the linkage rod 19, the scraper 8 is disengaged from the hanger 4. After the scraper 8 is disengaged from the hanger 4, as the lifting bar 5 continues to move downward, the spring 6 and the sealing block 7 drive the hanger 4 to move downward and reset.
[0044] Working principle: During use, the suspension 2 drives the cover 3 to move along the track 1. When the first gear 12 meshes with the first rack 13, it drives the transmission shaft 10 to rotate, and the reciprocating screw 11 rotates synchronously. During the entire meshing process of the first gear 12 and the first rack 13, the lifting bar 5 is moved from the bottom end of the reciprocating screw 11 to its top end. When the lifting bar 5 moves upward, the spring 6 and the sealing block 7 drive the hanger 4 to move upward along the inner wall of the adapter groove 15. The adapter groove 15 removes the powder or solidified layer on the outer walls of both sides of the hanger 4. When the bottom of the sealing block 7 and the limiting block 26 abuts... When the connection is made, the sealing block 7 and the hanger 4 stop moving upward. At this time, the hanger 4 reaches the set position, that is, it is at the same horizontal line as the scraper groove 9. As the lifting bar 5 moves upward, it drives the light bar 20 and the third rack 21 to move upward synchronously. At the same time as the hanger 4 reaches the set position, the third rack 21 begins to mesh with the second gear 22. As the lifting bar 5 continues to move upward, the spring 6 is stretched. The third rack 21 drives the second gear 22 to rotate, and the lead screw 17 rotates accordingly, driving the slider 18 to move along the outer wall of the second guide rod 28 towards the hanger 4. The scraper 8 is driven through the linkage rod 19. Synchronous movement: When the scraper 9 comes into contact with the inner and outer walls of the hanger 4, it removes the powder or solidified layer from the inner and outer walls of the hanger 4, achieving timely cleaning of the hanger 4. This avoids the problem of powder or solidified layer accumulating on the hanger 4 and affecting its conductive contact with the metal profile, while also preventing residual powder from the hanger 4 from falling and contaminating subsequent metal profiles. When the first gear 12 moves to mesh with the second rack 14, it drives the transmission shaft 10 and the reciprocating screw 11 to continue rotating. During the entire meshing process of the first gear 12 and the second rack 14, it drives the lifting bar 5 to move down from the top of the moving reciprocating screw 11 to its... At the bottom, as the lifting bar 5 moves downward, the spring 6 contracts accordingly. Through the meshing of the third rack 21 and the second gear 22, the lead screw 17 rotates in the opposite direction, which in turn drives the slider 18 to move away from the hanger 4. Then, through the linkage rod 19, the scraper 8 is disengaged from the hanger 4. After the scraper 8 is disengaged from the hanger 4, as the lifting bar 5 continues to move downward, the spring 6 and the sealing block 7 drive the hanger 4 to move downward and reset. After the hanger 4 is cleaned, the staff hangs the metal profile on the hanger 4. The metal profile on the hanger 4 is then driven into the powder spraying chamber and the curing chamber in sequence.
