Abstract
Description
Technical Field
[0001] This utility model relates to the field of luggage handle spraying technology, specifically a spraying device for processing luggage handles. Background Technology
[0002] In the production of bags and luggage, the pull rod is a core load-bearing component. Its surface coating treatment not only needs to meet the functional requirements of corrosion resistance and wear resistance, but also needs to ensure that the coating is uniform and consistent in order to improve the overall quality of the product. In the scenario of small-batch bag and luggage production, companies usually pursue the simplicity and low cost of the coating equipment.
[0003] The solution mainly includes a disc that can rotate around its own axis. A painting assembly is fixedly installed on one side of the disc, and multiple spaced positioning rods are vertically fixed on the upper surface of the disc. During operation, the operator places the hollow tie rods to be painted one by one onto the positioning rods. The drive mechanism drives the disc to rotate, causing the mounted tie rods to revolve with the disc and pass through the painting area of the painting assembly in sequence, achieving synchronous painting of multiple tie rods.
[0004] However, the existing device has significant technical defects: the positioning rod only serves as a support and positioning tool and cannot drive the pull rod to rotate. When the pull rod revolves with the disc and passes the paint spraying assembly, only the side facing the nozzle can directly receive the paint, while the other side away from the nozzle cannot get uniform spraying due to obstruction, which easily leads to problems such as missed spraying and uneven coating thickness. To correct this defect, an additional secondary spraying or manual touch-up process is required, which not only prolongs the processing cycle and reduces the overall spraying efficiency, but also increases labor costs. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a spraying device for processing luggage handles.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, the present invention provides the following technical solution: a spraying device for processing luggage handles, comprising a spraying table, wherein the spraying table is provided with a slot, a disc is rotatably arranged in the slot, and multiple vertical rods are rotatably arranged on the disc;
[0009] Multiple painting components are arranged in symmetrical slots at the upper end of the spray booth.
[0010] A gear ring is fixedly installed at the lower edge of the disc, and a machine box is fixedly installed at the upper end of the spray painting station. A motor is installed inside the machine box, and a rotating shaft that passes through the spray painting station is installed at the output end of the motor. A gear is installed at the bottom end of the rotating shaft. The gear is located on one side of the gear ring and meshes with the gear ring. A first gear plate is fixedly installed at the lower end of the vertical rod, and a second gear plate is fixedly installed below the spray painting station. Multiple first gear plates are located on the periphery of the second gear plate, and multiple first gear plates mesh with the second gear plate.
[0011] To make the tie rod workpiece more stable when placed on the vertical rod, the present invention includes an improvement in that the vertical rod is provided with an anti-slip sleeve, which is penetrated by the vertical rod. The anti-slip sleeve is made of rubber and is fixed to the vertical rod by friction.
[0012] To improve the stability of the vertical rod during rotation, the present invention includes the following improvements: the disc has a through hole, a first sealed bearing is embedded in the through hole, the vertical rod passes through the first sealed bearing, and the vertical rod is interference-fitted with the inner ring of the first sealed bearing; a second sealed bearing is embedded in the slot, the outer ring of the second sealed bearing is interference-fitted with the inner wall of the slot, and the inner ring of the second sealed bearing is interference-fitted with the outer wall of the disc.
[0013] Furthermore, the improvement of this utility model is that the spray painting assembly includes a support rod and multiple fixing brackets. The bottom end of the support rod is fixed to the upper end of the spray painting station by screws. The multiple fixing brackets are all fixed to the inner side of the support rod. Two spray heads are symmetrically arranged at both ends of the fixing brackets. A diverter pipe is fixed to the outer side of the support rod. A transfer pipe is provided in the middle part of the diverter pipe. The diverter pipe and the spray head are connected through a conduit. Both the diverter pipe and the conduit are made of metal.
[0014] To facilitate the assembly of the second gear plate, the present invention includes an improvement in which a positioning rod is fixedly installed at the center of the second gear plate, a U-shaped rod is provided at the lower end of the positioning rod, and support rods are vertically installed at both ends of the U-shaped rod. The top end of the support rod is fixed to the lower end of the spray booth by screws.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a spraying device for processing luggage handles, which has the following beneficial effects:
[0017] The disk revolves by meshing the gear and gear ring driven by the motor. At the same time, the meshing transmission between the first gear disk and the fixed second gear disk causes the vertical rod to drive the tie rod workpiece to rotate synchronously, forming a dual motion mode of "revolution + rotation". This completely solves the defect of single-sided spraying of the tie rod and missed spraying on the side away from the nozzle in the existing technology, ensuring that the coating thickness on the tie rod surface is uniform and consistent, greatly improving the spraying quality and product appearance consistency, and eliminating the need for additional touch-up spraying.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a spraying device for processing luggage handles, including a spraying table 1, a slot 2 on the spraying table 1, a disc 3 rotatably arranged in the slot 2, and multiple vertical rods 4 rotatably arranged on the disc 3.
[0025] Multiple spraying components are provided in the symmetrical empty slots 2 at the upper end of the spray booth 1;
[0026] A gear ring 6 is fixedly installed at the lower edge of the disc 3. A machine housing 7 is fixedly installed at the upper end of the spray painting station 1. A motor is installed inside the machine housing 7. The output end of the motor is provided with a rotating shaft that passes through the spray painting station 1. A gear 8 is provided at the bottom end of the rotating shaft. The gear 8 is located on one side of the gear ring 6 and meshes with the gear ring 6. A first gear disc 9 is fixedly installed at the lower end of the vertical rod 4. A second gear disc 10 is fixedly installed below the spray painting station 1. Multiple first gear discs 9 are located on the periphery of the second gear disc 10, and multiple first gear discs 9 mesh with the second gear disc 10.
[0027] Preliminary preparations:
[0028] The adapter pipe 15 of the paint spraying assembly is precisely connected to the external paint delivery pipeline to ensure that the paint delivery channel is smooth and leak-free;
[0029] The vertical rod 4 is provided with an anti-slip sleeve 5, which is penetrated by the vertical rod 4. The anti-slip sleeve 5 is made of rubber and is fixed to the vertical rod 4 by friction.
[0030] According to the specifications of the luggage handle to be painted, select a suitable rubber anti-slip sleeve 5 and put it on the vertical rod 4. The friction between the anti-slip sleeve 5 and the vertical rod 4 is used to achieve a stable assembly.
[0031] Then, the tie rod workpieces to be processed are placed one by one on the outside of the anti-slip sleeve 5. The elastic clamping force and friction of the anti-slip sleeve 5 are used to keep the tie rod workpieces in a vertical and stable position, so as to avoid displacement or shaking during the spraying process.
[0032] Equipment startup and spraying operation:
[0033] The painting assembly includes a support rod 13 and multiple fixing brackets 16. The bottom end of the support rod 13 is fixed to the upper end of the painting station 1 with screws. The multiple fixing brackets 16 are all fixed to the inner side of the support rod 13. Two nozzles 17 are symmetrically arranged at both ends of the fixing brackets 16. A diversion pipe 14 is fixed to the outer side of the support rod 13. A transfer pipe 15 is provided in the middle part of the diversion pipe 14. The diversion pipe 14 and the nozzles 17 are connected through a conduit 18. Both the diversion pipe 14 and the conduit 18 are made of metal.
[0034] Turn on the external feed pump and the motor in the machine box 7. The feed pump pressurizes the paint and delivers it to the distribution pipe 14. The paint is then distributed to each nozzle 17 through the conduit 18. The paint is then evenly atomized and sprayed out from the nozzle 17.
[0035] After the motor starts, it drives the gear 8 to rotate through the shaft. The gear 8 meshes with the gear ring 6 at the lower end of the disc 3, driving the disc 3 to rotate smoothly under the support of the second sealed bearing in the slot 2.
[0036] A positioning rod 12 is fixedly installed at the center of the second gear plate 10. A U-shaped rod 11 is provided at the lower end of the positioning rod 12. Support rods are vertically installed at both ends of the U-shaped rod 11. The top end of the support rod is fixed to the lower end of the spray booth 1 by screws. The screw fixing method makes the second gear plate 10 easy to assemble.
[0037] At the same time, the first toothed disc 9 at the lower end of the vertical rod 4 continuously meshes with the fixed second toothed disc 10. Under the traction of the revolving disc 3, the vertical rod 4 achieves synchronous rotation with the help of the first sealed bearing 19 on the disc 3, thereby driving the pull rod workpiece sleeved on it to rotate with the disc 3 and pass through the spraying area of each paint spraying component in sequence, while rotating at a constant speed to ensure that all parts of the pull rod surface can receive the spraying in all directions.
[0038] Work completion and component maintenance:
[0039] After the tie rod workpiece has been fully and evenly coated, turn off the motor and the feed pump, and carefully remove the coated tie rod.
[0040] If the anti-slip sleeve 5 becomes worn or aged, or if it needs to be adapted to different sizes of pull rods, simply apply a moderate pulling force to the anti-slip sleeve 5. When the pulling force exceeds the friction between it and the vertical rod 4, the anti-slip sleeve 5 can be easily removed and replaced with a new, compatible anti-slip sleeve 5. The operation is simple and efficient.
[0041] The rubber anti-slip sleeve 5, with its own elasticity and friction, can firmly fix the pull rod workpiece, preventing it from shifting during dual movements, and can also avoid damage to the pull rod surface caused by rigid contact.
[0042] Meanwhile, the anti-slip sleeve 5 can be flexibly replaced according to the inner diameter of the pull rod, adapting to the processing needs of pull rods of different specifications and improving the versatility of the equipment.
[0043] The disk 3 has a through hole, in which a first sealed bearing 19 is embedded. A vertical rod 4 passes through the first sealed bearing 19, and the vertical rod 4 is interference-fitted with the inner ring of the first sealed bearing 19. A second sealed bearing is embedded in the slot 2, and the outer ring of the second sealed bearing is interference-fitted with the inner wall of the slot 2. The inner ring of the second sealed bearing is interference-fitted with the outer wall of the disk 3.
[0044] The second sealed bearing between the disc 3 and the empty groove 2, and the first sealed bearing 19 between the vertical rod 4 and the disc 3, effectively reduce the frictional resistance during rotation, ensure the stability of the revolution of the disc 3 and the rotation of the vertical rod 4, and reduce component wear.
[0045] The painting assembly uses metal diversion pipes 14 and conduits 18, which have a stable structure and ensure smooth paint delivery, further extending the overall service life of the equipment.
[0046] The multi-nozzle 17-combination design expands the spraying coverage area. Combined with dual motion modes, it enables simultaneous and efficient spraying of multiple tie rods, significantly shortening the processing cycle. It eliminates the need for secondary touch-up spraying and manual correction, reducing labor input and paint waste, and lowering production costs. At the same time, the number of spraying components can be flexibly increased or decreased according to production needs. The components are easy to disassemble and maintain, taking into account the demands of small-scale production for equipment simplicity and low cost.
