Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically to an automatic powder coating production line. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. The speed reducer end cover is an important component of the speed reducer. In order to improve the service life of the speed reducer end cover, it is usually necessary to use electrostatic powder spraying technology to spray a powder coating on the surface of the speed reducer end cover.

[0003] Currently, electrostatic spraying of existing gearbox end covers is usually done manually. The working principle is as follows: the worker holds an electrostatic spray gun, picks up the gearbox end cover to be sprayed, and starts the electrostatic spray gun to spray a powder coating onto the surface of the gearbox end cover.

[0004] In the above-mentioned solution, the existing technology involves workers using handheld electrostatic spray guns to spray each reducer end cover individually, which is inefficient and easily causes powder to fly around, posing a significant health hazard to workers. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic powder spraying production line. By equipping it with a lifting mechanism and an electrostatic spraying component, it can automatically perform electrostatic spraying on multiple reducer end covers, solving the problem of low work efficiency in the prior art, while not causing harm to the health of workers.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] An automatic powder coating production line includes a frame and an overhead chain conveyor. A mounting frame is provided on each side of the frame, and a lifting mechanism is installed on each mounting frame. An electrostatic spraying component is provided on one side of the lifting mechanism. Multiple first hooks are installed at the lower end of the overhead chain conveyor, and lifting devices are suspended from the first hooks. Multiple reducer end caps are suspended from the lifting devices. A tilting assembly is provided at the bottom of the frame, and a tilting plate is provided on the tilting assembly. A powder recovery bin is fixed at the lower end of the frame, located directly below the tilting plate.

[0008] When electrostatic spraying is required on the end covers of the speed reducers, multiple end covers are suspended on a lifting device. The overhead conveyor is then started, moving the first hook. The movement of the first hook moves the lifting device, which in turn moves the multiple end covers between two sets of electrostatic spraying components. The overhead conveyor is then stopped, and two lifting mechanisms are started, causing the two sets of electrostatic spraying components to reciprocate. Simultaneously, the two sets of electrostatic spraying components are activated, thus spraying a powder coating onto the surface of the multiple end covers. This automates the electrostatic spraying of the speed reducer end covers, improves work efficiency, and does not harm the health of workers. After the electrostatic spraying is completed, the overhead conveyor is started again, moving the multiple sprayed end covers outward. The tilting component is then activated, causing the tilting plate to tilt. The tilting plate carries the powder that has fallen onto its upper surface to the powder recovery bin, allowing for powder recycling.

[0009] By incorporating a lifting mechanism and electrostatic spraying components, multiple reducer end covers can be automatically electrostatically sprayed, solving the problem of low work efficiency in existing technologies, while also avoiding harm to the health of workers.

[0010] The utility model is further configured such that: the lifting mechanism includes a guide component and a lifting component, the guide component includes two slide rails symmetrically fixed on the side wall of the mounting frame, the same slider is slidably connected on the two slide rails, and the electrostatic spraying component is disposed on the side wall of the slider.

[0011] The above technical solution enables the slider to rise and fall smoothly and stably, thereby driving the electrostatic spraying assembly to rise and fall smoothly and stably, thus improving the stability of the electrostatic spraying assembly during the rising and falling process.

[0012] The utility model is further configured such that: the lifting assembly includes a first motor fixed to the top of the mounting frame, a screw is rotatably connected to the bottom of the mounting frame, the screw is screwed to the slider, and the screw passes through the protruding end of the slider and is fixedly connected to the output end of the first motor.

[0013] With the above technical solution, when it is necessary to drive the electrostatic spraying component to reciprocate, the first motor is started, which drives the screw to rotate clockwise. The clockwise rotation of the screw drives the slider to move upward, thereby driving the electrostatic spraying component to move upward to the desired position. Then, the first motor drives the screw to rotate counterclockwise, which drives the slider to move downward, thereby driving the electrostatic spraying component to move downward to the desired position. The above operation is repeated to drive the electrostatic spraying component to reciprocate.

[0014] The utility model is further configured such that: the electrostatic spraying assembly includes a powder guide tube on the side wall of the fixed slider, multiple electrostatic spray guns are fixed at equal intervals on the side wall of the powder guide tube, and multiple through holes for the electrostatic spray guns to pass through are formed on the side wall of the frame.

[0015] The above technical solution allows for electrostatic spraying of multiple reducer end covers. Powder is filled into the powder conduit, and the powder conduit is driven to reciprocate by a lifting mechanism. At the same time, multiple electrostatic spray guns are activated, causing the powder to be sprayed out from the nozzles of the electrostatic spray guns, thereby spraying a powder coating onto the surface of multiple reducer end covers.

[0016] The utility model is further configured such that: the lifting device includes a connecting strip, multiple connecting rods are fixed at equal intervals on the side wall of the connecting strip, multiple hooks are symmetrically fixed on both sides of the connecting rods, and a second lifting hook is formed by bending the top of the connecting strip.

[0017] With the above technical solution, when it is necessary to move multiple reducer end covers, the second hook is suspended on the first hook, and then multiple reducer end covers are suspended on the hook. The suspension chain conveyor is started to move the first hook. The movement of the first hook moves the connecting bar and multiple connecting rods, thereby simultaneously moving multiple reducer end covers suspended on the hook.

[0018] The utility model is further configured such that: the flipping assembly includes a connecting shaft rotatably connected to the bottom end of the frame, a flipping plate is fixed to the side wall of the connecting shaft, a first gear is fixed to one end of the connecting shaft, a second gear meshing with the first gear is rotatably connected to the side wall of the frame, a second motor is fixed to the side wall of the frame, and the output end of the second motor is fixed to the side wall of the second gear.

[0019] With the above technical solution, when it is necessary to recycle the powder that has fallen onto the top of the flipping plate, the second motor is started, which drives the second gear to rotate. The rotation of the second gear drives the first gear to rotate, and the rotation of the first gear drives the connecting shaft to rotate. The rotation of the connecting shaft drives the flipping plate to flip, thereby transporting the powder that has fallen onto the top of the flipping plate to the powder recycling bin.

[0020] The utility model is further configured such that a rubber strip is fixed on the inner wall of each end of the through hole.

[0021] Through the above technical solution, during the electrostatic spraying process of the electrostatic spray gun on the reducer end cover, a rubber strip is provided to prevent powder from flying out and affecting the surrounding environment.

[0022] The beneficial effects of this utility model are:

[0023] Compared with existing technologies, this technology, by incorporating a lifting mechanism and electrostatic spraying components, can automatically perform electrostatic spraying on multiple reducer end covers, solving the problem of low work efficiency in existing technologies, while also avoiding harm to the health of workers.

[0024] By incorporating rubber strips, powder is prevented from flying out and affecting the surrounding environment. Attached Figure Description

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] The following is for reference Figures 1 to 4 This utility model will now be described.

[0032] An automatic powder coating production line includes a frame 1 and an overhead chain conveyor 2. A mounting frame 3 is provided on each side of the frame 1. A lifting mechanism is installed on each mounting frame 3, and an electrostatic spraying component is provided on one side of the lifting mechanism. Multiple first hooks 4 are installed at the lower end of the overhead chain conveyor 2, with lifting devices suspended from the first hooks 4. Multiple reducer end caps 5 are suspended from the lifting devices. A tilting assembly is provided at the bottom of the frame 1, with a tilting plate 6 on the tilting assembly. A powder recovery bin 7 is fixed at the lower end of the frame 1, located directly below the tilting plate 6.

[0033] When electrostatic spraying is required on the reducer end covers 5, multiple reducer end covers 5 are suspended on the lifting device. The overhead conveyor 2 is then started, which moves the first hook 4. The movement of the first hook 4 moves the lifting device, and the movement of the lifting device moves multiple reducer end covers 5 between the two sets of electrostatic spraying components. The overhead conveyor 2 is then stopped, and the two sets of lifting mechanisms are started, which drive the two sets of electrostatic spraying components to reciprocate. At the same time, the two sets of electrostatic spraying components are started, thereby spraying a powder coating onto the surface of multiple reducer end covers 5. This automates the electrostatic spraying of the reducer end covers 5, improves work efficiency, and does not harm the health of the workers. After the electrostatic spraying is completed, the overhead conveyor 2 is started, which moves the multiple sprayed reducer end covers 5 outward. The tilting component is then started, which tilts the tilting plate 6. The tilting plate 6 tilts and carries the powder that has fallen onto the top of the tilting plate 6 to the powder recovery bin 7, where the powder can be recycled.

[0034] By incorporating a lifting mechanism and electrostatic spraying components, multiple reducer end covers 5 can be automatically electrostatically sprayed, solving the problem of low work efficiency in existing technologies, while also avoiding harm to the health of workers.

[0035] The lifting mechanism includes a guide assembly and a lifting assembly. The guide assembly includes two slide rails 8 symmetrically fixed on the side wall of the mounting frame 3. The same slider 9 is slidably connected on the two slide rails 8. The electrostatic spraying assembly is set on the side wall of the slider 9.

[0036] This allows the slider 9 to rise and fall smoothly and stably, thereby smoothly and stably driving the electrostatic spraying assembly to rise and fall, thus improving the stability of the electrostatic spraying assembly during the rising and falling process.

[0037] The lifting assembly includes a first motor 10 fixed to the top of the mounting frame 3. A screw 11 is rotatably connected to the bottom of the mounting frame 3. The screw 11 is screwed to the slider 9. The screw 11 passes through the protruding end of the slider 9 and is fixedly connected to the output end of the first motor 10.

[0038] When the electrostatic spraying assembly needs to reciprocate, the first motor 10 is started, which drives the screw 11 to rotate clockwise. The clockwise rotation of the screw 11 causes the slider 9 to move upward, thereby moving the electrostatic spraying assembly upward to the desired position. Then, the first motor 10 drives the screw 11 to rotate counterclockwise, which causes the slider 9 to move downward, thereby moving the electrostatic spraying assembly downward to the desired position. The above operation is repeated to drive the electrostatic spraying assembly to reciprocate.

[0039] The electrostatic spraying assembly includes a powder conduit 12 fixed on the side wall of the slider 9, multiple electrostatic spray guns 13 fixed at equal intervals on the side wall of the powder conduit 12, and multiple through holes 101 formed on the side wall of the frame 1 for the electrostatic spray guns 13 to pass through.

[0040] When multiple reducer end covers 5 need to be electrostatically sprayed, powder is filled into the powder guide tube 12, and the powder guide tube 12 is driven to reciprocate by the lifting mechanism. At the same time, multiple electrostatic spray guns 13 are started, so that the powder is sprayed out from the nozzle of the electrostatic spray gun 13, thereby spraying a powder coating on the surface of multiple reducer end covers 5.

[0041] The lifting device includes a connecting bar 14, on which multiple connecting rods 15 are fixed at equal intervals. Multiple hooks 16 are symmetrically fixed on both sides of the connecting rods 15. The top of the connecting bar 14 is bent into a second hook 1401.

[0042] When it is necessary to move multiple reducer end covers 5, the second hook 1401 is suspended on the first hook 4, and then multiple reducer end covers 5 are suspended on the hook 16. The overhead conveyor 2 is started to move the first hook 4. The movement of the first hook 4 moves the connecting bar 14 and multiple connecting rods 15, thereby simultaneously moving multiple reducer end covers 5 suspended on the hook 16.

[0043] The flipping assembly includes a connecting shaft 17 rotatably connected to the bottom of the frame 1, a flipping plate 6 fixed to the side wall of the connecting shaft 17, a first gear 18 fixed to one end of the connecting shaft 17, a second gear 19 rotatably connected to the side wall of the frame 1 and meshing with the first gear 18, a second motor 20 fixed to the side wall of the frame 1, and the output end of the second motor 20 fixed to the side wall of the second gear 19.

[0044] When it is necessary to recycle the powder that has fallen onto the top of the flip plate 6, the second motor 20 is started, which drives the second gear 19 to rotate. The rotation of the second gear 19 drives the first gear 18 to rotate, and the rotation of the first gear 18 drives the connecting shaft 17 to rotate. The rotation of the connecting shaft 17 drives the flip plate 6 to flip, thereby conveying the powder that has fallen onto the top of the flip plate 6 to the powder recycling bin 7.

[0045] A rubber strip 21 is fixed on the inner wall of each end of the through hole 101.

[0046] During the electrostatic spraying process of the electrostatic spray gun 13 on the reducer end cover 5, the rubber strip 21 is provided to prevent powder from flying out and affecting the surrounding environment.

[0047] Working principle:

[0048] When electrostatic spraying is required on the reducer end caps 5, multiple reducer end caps 5 are suspended on hooks 16. The overhead conveyor 2 is started, driving the first hook 4 to move. The movement of the first hook 4 drives the connecting bar 14 and multiple connecting rods 15 to move, thereby moving multiple reducer end caps 5 suspended on hooks 16 between two sets of powder guide tubes 12 and multiple electrostatic spray guns 13. Then, the overhead conveyor 2 is stopped, and the first motor 10 is started, driving the screw 11 to rotate clockwise. The clockwise rotation of the screw 11 drives the slider 9 to move upward, thereby moving the powder guide tubes 12 and multiple electrostatic spray guns 13 upward. Then, the first motor 10 drives the screw 11 to rotate counterclockwise, and the counterclockwise rotation of the screw 11 drives the slider 9 to move downward, thereby moving the powder guide tubes 12 and multiple electrostatic spray guns 13 upward. The tube 12 and multiple electrostatic spray guns 13 move downwards, repeating the above operation, thereby driving the two sets of powder guide tubes 12 and multiple electrostatic spray guns 13 to reciprocate. At the same time, multiple electrostatic spray guns 13 are started, so that powder is sprayed out from the nozzle of the electrostatic spray gun 13, thereby spraying a powder coating on the surface of multiple reducer end covers 5. When the electrostatic spraying work is completed, the overhead chain conveyor 2 is started, driving multiple sprayed reducer end covers 5 to move outwards. The second motor 20 is started, driving the second gear 19 to rotate. The rotation of the second gear 19 drives the first gear 18 to rotate. The rotation of the first gear 18 drives the connecting shaft 17 to rotate. The rotation of the connecting shaft 17 drives the tilting plate 6 to tilt, thereby carrying the powder that has fallen on the top of the tilting plate 6 to be transported into the powder recovery bin 7.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
