Description

Technical Field

[0001] This utility model relates to the field of overhead conveyor technology, and in particular to an overhead conveyor mechanism for a spraying production line that is adaptable to various workpiece sizes. Background Technology

[0002] Spraying is a processing method that uses a spray gun to atomize paint and apply it to the surface of an object. During spraying, the product to be sprayed is fixed on a rotatable bracket, and then the rotatable bracket is placed on a suspended conveyor mechanism. Through the movement of the suspended conveyor mechanism and the continuous rotation of the bracket, the paint is evenly sprayed onto the surface of the product.

[0003] Currently, in the use of overhead conveyor mechanisms in painting production lines, the workpiece is generally hung directly on the hook of the bracket, and then the drive mechanism drives the hook to rotate, thereby controlling the rotation of the workpiece. However, in the existing technology, directly driving the workpiece to rotate through the hook is prone to causing the workpiece to shake, resulting in uneven spraying. Driving the workpiece to rotate by clamping and then driving the clamping structure to rotate is prone to causing the surface of the clamping structure to be sprayed with more paint, reducing the practicality of the overhead conveyor mechanism in the painting production line. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing spray painting production line overhead conveyor mechanism is prone to shaking or paint pollution and waste when rotating, and to propose a spray painting production line overhead conveyor mechanism that is adaptable to various workpiece sizes.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a support plate and a drive motor. Gears are rotatably connected to both ends of the bottom surface of the support plate. A drive motor is mounted on the top surface of the support plate above one of the gears. The output end of the drive motor rotatably passes through the support plate and is fixed to the top surface of the gear. A chain is meshed and sleeved on two of the gears. Several fixing plates are equidistantly fixed to the outer surface of the chain. A detachable support sleeve is fixed on the fixing plate. A fixable adjustable clamp is slidably sleeved inside the support sleeve. Rotary discs are rotatably connected to opposite sides of the two adjustable clamps. A hook is fixed to the bottom surface of the upper rotating disc. A servo motor is mounted on the bottom surface of the lower adjustable clamp. The output end of the servo motor rotatably passes through the adjustable clamp and is fixed to the bottom surface of the lower rotating disc.

[0006] Preferably, both gears are meshed with cleaning cotton rollers on their sides, and the top surfaces of the cleaning cotton rollers are rotatably connected to connecting plates. A fixing block is fixed to the top surface of the connecting plate, and a fixing screw is fixed to the top surface of the fixing block. The fixing block and the fixing screw are inserted inside the support plate, and a nut is threaded onto one end of the fixing screw that extends to the top surface of the support plate.

[0007] Preferably, the fixing plate has symmetrical fixing holes inside, and the supporting sleeve plate has symmetrical connecting screws fixed on the side facing the fixing plate. The end of the connecting screw that extends to the outside of the fixing hole is threaded with a nut.

[0008] Preferably, the two adjusting clamps are arranged in an L-shape facing each other. Each of the two adjusting clamps has an adjusting groove inside. A fixing screw is slidably sleeved inside the adjusting groove. The fixing screw is fixed inside the adjusting clamp. A fixing block is threaded onto one end of the fixing screw that extends to the outside of the support plate.

[0009] Preferably, the support sleeve has a through groove inside that mates with the adjusting clamp, and the support sleeve has an active groove on the side near the fixing plate that mates with the fixing screw and the fixing clamp.

[0010] Preferably, the hook is J-shaped, the bottom of the hook is horizontal, and the centers of the upper and lower rotating disks are on the same vertical line.

[0011] Preferably, the cleaning cotton roller is configured with teeth that cooperate with gears, the top of the support plate has a square fixing groove that cooperates with the fixing block, and the diameter of the second fixing screw is smaller than the length of the fixing block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the adjustable clamping method facilitates the clamping of the workpiece and then drives the workpiece and the rotating disk to rotate. This avoids paint pollution and ensures the stability of the workpiece during rotation. It solves the problem that the existing hanging conveyor mechanism of the spraying production line is prone to shaking or paint pollution and waste during rotation, and improves the practicality of the hanging conveyor mechanism of the spraying production line.

[0014] 2. In this utility model, the cleaning cotton roller that meshes with the gear can clean the gear in time when conveying the workpiece, avoiding excess paint mist droplets falling on the gear and forming a protective layer on the gear surface, thereby ensuring the cleanliness of the gear surface.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0022] like Figure 1-4 As shown, this utility model provides a suspended conveyor mechanism for a spraying production line that is adaptable to various workpiece sizes. It includes a support plate 1 and a drive motor 2. Gears 3 are rotatably connected to both ends of the bottom surface of the support plate 1. The drive motor 2 is installed on the top surface of the support plate 1 above one of the gears 3. The output end of the drive motor 2 rotates through the support plate 1 and is fixed to the top surface of the gear 3. Chains 4 are meshed on the two gears 3. Several fixing plates 5 are fixed at equal intervals on the outer surface of the chain 4. A detachable support sleeve 6 is fixed on the fixing plate 5. A fixable adjustable clamp 8 is slidably fitted inside the support sleeve 6. A through groove is opened inside the support sleeve 6 to cooperate with the adjustable clamp 8. Rotating disks 9 are rotatably connected to the opposite sides of the two adjustable clamps 8. A hook 10 is fixed on the bottom surface of the upper rotating disk 9. The hook 10 is J-shaped and the bottom of the hook 10 is horizontal. The centers of the upper and lower rotating disks 9 are on the same vertical line. A servo motor 11 is installed on the bottom surface of the lower adjustable clamp 8. The output end of the servo motor 11 rotates through the adjustable clamp 8 and is fixed to the bottom surface of the lower rotating disk 9.

[0023] The specific settings and functions of this embodiment are described in detail below: The fixing plate 5 has symmetrical fixing holes inside. Each side of the support sleeve 6 facing the fixing plate 5 has a symmetrically fixed connecting screw 7. The end of each connecting screw 7 extending through the fixing hole is threaded with a nut, facilitating the disassembly and installation of the support sleeve 6. The two adjusting clamps 8 are arranged in an L-shape facing each other. Each adjusting clamp 8 has an adjusting groove 12 inside. A fixing screw 13 is slidably fitted inside the adjusting groove 12. The fixing screw 13 is fixed inside the adjusting clamp 8. The end of the fixing screw 13 extending to the outside of the support plate 1 is threaded with a fixing block 14. The side of the support sleeve 6 closest to the fixing plate 5 has an active groove that cooperates with the fixing screw 13 and the fixing block 14. By turning the fixing block 14, the fixing between the two adjusting clamps 8 and the support sleeve 6 can be released, thus facilitating the adjustment of the distance between the two rotating disks 9. Example

[0024] like Figure 1-4 As shown, two gears 3 are meshed with cleaning cotton rollers 16 on their sides. The cleaning cotton rollers 16 are set in a tooth shape to cooperate with the gears 3. The top surface of each cleaning cotton roller 16 is rotatably connected to a connecting plate 15. A fixing block 17 is fixed on the top surface of the connecting plate 15. A fixing screw 18 is fixed on the top surface of the fixing block 17. The fixing block 17 and the fixing screw 18 are inserted into the support plate 1. A nut is threaded onto one end of the fixing screw 18 that extends through to the top surface of the support plate 1. A square fixing groove that cooperates with the fixing block 17 is opened on the top of the support plate 1. The diameter of the fixing screw 18 is smaller than the length of the fixing block 17.

[0025] The overall effect of this embodiment is that by rotating the gear 3, the cleaning cotton roller 16 is driven to rotate, and the gear 3 is wiped by the cleaning cotton roller 16 engaging with the gear 3 when it rotates. This makes it easier to maintain and clean the gear 3 during use, while ensuring the service life of the cleaning cotton roller 16.

[0026] The operating method and working principle of this device are as follows: When conveying a workpiece, the workpiece is suspended on the hook 10, and the lower adjusting clamp 8 is held in place. The fixing clamp 14 is turned to release the clamping of the adjusting clamp 8. At this time, the upper adjusting clamp 8 moves downwards under the action of the workpiece and its own weight, so that the bottom of the workpiece abuts against the top surface of the lower rotating disk 9. The fixing clamp 14 is then turned again to clamp both adjusting clamps 8, thus suspending and fixing the workpiece on the adjusting clamp 8. At this time, the drive motor 2 runs, driving the gear 3 to rotate. The rotation of the gear 3 drives the chain 4 to move, thereby moving the workpiece for loading. When the workpiece moves to the spraying position, the servo motor 11 runs, driving the chain 4 to rotate. Rotating the rotating disk 9 drives the workpiece clamped between the two rotating disks 9 to rotate, ensuring the uniformity of the spraying. When the gear 3 rotates, it drives the cleaning cotton roller 16 to rotate. During the rotation, the cleaning cotton roller 16 contacts the surface of the gear 3 and wipes the surface of the gear 3, cleaning the paint droplets that have just fallen on the surface of the gear 3. When it is necessary to replace the cleaning cotton roller 16, tighten the nut to release the fixing screw 18 from the support plate 1. Pull the cleaning cotton roller 16 down to pull out the fixing block 17 and the fixing screw 18, so that the cleaning cotton roller 16 can be replaced. Insert the fixing block 17 and the fixing screw 18 on the top surface of the new cleaning cotton roller 16 into the support plate 1 and fix it with the nut.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
