DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] With reference to Figure 1 - Figure 3 An embodiment provided by the utility model: a kind of fine-diameter enameled aluminium wire mould method paint spraying machine, including bottom plate 1, its function is to provide support basis for entire paint spraying machine, bottom plate 1 top is fixedly connected with protection box 2, protection box 2 is made of metal sheet, its function is to protect inside adjusting assembly, paint spraying component etc. from the influence of external dust, sundries, simultaneously play certain safety protection function, protection box 2 left and right side wall is provided with roller assembly, protection box 2 is provided with adjusting assembly inside;

[0035] The adjustment assembly includes a fixing ring 10. A fixing component is provided on the outer wall of the fixing ring 10 to securely install the fixing ring 10 inside the protective box 2. Multiple base posts 11 are slidably connected inside the fixing ring 10. A connecting post 14 is fixedly connected to the top of each base post 11, connecting the base post 11 to the paint spraying assembly and transmitting the movement of the base post 11. A paint spraying assembly is provided on the top of each connecting post 14. A buffer spring 13 is sleeved on the outer wall of each connecting post 14, providing cushioning during the movement of the paint nozzle 12 to prevent rigid collisions between components. One end of each buffer spring 13 is fixedly connected to the top of the connecting post 14, and the other end is fixedly connected to the inside of the fixing ring 10. A rotating ring 8 is slidably connected to the outer wall of the fixing ring 10. The rotation of the rotating ring 8 causes the inclined groove 9 to shift, thereby driving the bottom column 11 and the connecting column 14 to move. The inclined groove 9 is formed inside the rotating ring 8 by machining, creating a groove with a certain inclination angle. The outer wall of the connecting column 14 is slidably connected to the inclined groove 9. When the rotating ring 8 rotates, the displacement of the inclined groove 9 causes the connecting column 14 to move up and down under the action of the inclined surface. A connecting block 27 is fixedly connected to the top of the rotating ring 8, connecting the rotating ring 8 and the power assembly. The power assembly, including an electric actuator 26, is located on the side of the connecting block 27. This assembly provides power for the rotation of the rotating ring 8. The outer wall of the electric actuator 26 is fixedly connected to the top of the inner wall of the protective box 2. The output end of the electric actuator 26 is rotatably connected via a shaft pin. Connected inside the connecting block 27, when the output end of the electric actuator 26 extends or retracts, it can drive the connecting block 27 and the rotating ring 8 to rotate. The painting assembly includes multiple spray nozzles 12, whose function is to evenly spray paint onto the aluminum wire. The spray nozzles 12 are distributed in a circumferential shape inside the fixing ring 10, and the bottom of each spray nozzle 12 is fixedly connected to the top of the connecting post 14. The fixing assembly includes multiple fixing plates 15, which are made of metal plates. Their function is to fix the fixing ring 10 inside the protective box 2 to ensure the stability of the fixing ring 10. The side walls of the fixing plates 15 are fixedly connected to the inner wall of the protective box 2. A dryer 3 is provided on the side of the protective box 2. The dryer 3 is generally composed of a metal shell and an internal heating element. Its function is to dry the aluminum wire after spraying paint. To facilitate rapid curing of the paint, the dryer 3 is fixedly connected to the top of the base plate 1. Multiple heating plates 4, composed of ceramic material and resistance wire, are fixedly connected inside the dryer 3. Their function is to generate heat when energized, providing a heat source for drying the aluminum wire. The heating plates 4 are arranged in a circumferential pattern. A paint storage tank 5, made of plastic, is fixedly connected to the side wall of the protective box 2. Its function is to store the paint. A booster pump 7 is fixedly connected to the inner wall of the protective box 2. Its function is to increase the pressure of the paint, allowing it to be smoothly delivered to the spray nozzle 12 through the connecting pipe 6. Both the output and input ends of the booster pump 7 are fixedly connected to the connecting pipe 6, which is made of stretchable rubber. One end of the input connecting pipe 6 is fixedly connected to the top of the paint storage tank 5 for drawing paint from it.One end of the connecting pipe 6 of the output end is fixedly connected inside the rotating ring 8 to deliver the pressurized paint to the paint spraying nozzle 12.

[0036] Specifically, when using the fine-diameter enameled aluminum wire mold coating machine, first, the staff places the aluminum wire coil on the bearing column 17 on one side of the base plate 1, and then places the storage coil on the bearing column 17 on the other side. Then, one end of the aluminum wire is pulled out of the aluminum wire coil, sequentially passes through the roller assembly on the left and right side walls of the protection box 2, and then passes through the space between the heat plates 4 distributed in a circle inside the dryer 3. Finally, the aluminum wire is fixed on the storage coil. At this time, the drive motors 16 on both sides are started, and the output shaft of the drive motor 16 drives the bearing column 17 to rotate through the shaft coupling. The drive motor 16 on one side drives the bearing column 17 to rotate in the clockwise direction, so that the aluminum wire coil starts to release the wire. The drive motor 16 on the other side drives the bearing column 17 to rotate in the counterclockwise direction, so that the storage coil starts to wind the wire. Under the action of the bearing columns 17 on both sides, the aluminum wire moves linearly from the aluminum wire coil to the storage coil, sequentially passes through the paint spraying device inside the protection box 2 and the drying device inside the dryer 3 for paint spraying and drying operations.

[0037] When it is necessary to adjust the distance between the paint spraying devices according to the thickness of the aluminum wire to adapt to different paint spraying needs, the electric push rod 26 inside the protection box 2 is started. The output end of the electric push rod 26, i.e., the push rod, drives the displacement of the connecting block 27. The connecting block 27 is displaced in the same straight line direction as the movement direction of the output end of the electric push rod 26 under the driving of the output end of the electric push rod 26. Since the connecting block 27 is fixedly connected with the rotating ring 8, the linear displacement of the connecting block 27 is converted into the rotation of the rotating ring 8 around the circumference of the fixed ring 10. The rotation of the rotating ring 8 further causes the displacement of the plurality of inclined grooves 9 inside it. The inclined grooves 9 move in a circle around the central axis of the fixed ring 10 together with the rotating ring 8. Since the outer wall of the connecting column 14 is slidingly connected inside the inclined grooves 9, when the inclined grooves 9 are displaced, the connecting column 14 slides under the influence of the slope of the inclined grooves 9. The slope of the inclined grooves 9 causes the connecting column 14 to be subjected to an upward force. The connecting column 14 moves linearly upward along the track inside the fixed ring 10. The upward displacement of the connecting column 14 drives the upward displacement of the base column 11 as a whole through the fixed connection with the base column 11. The upward displacement of the connecting column 14 simultaneously drives the displacement of the paint spraying nozzle 12. Since the plurality of paint spraying nozzles 12 are distributed in a circle, each paint spraying nozzle 12 moves linearly in the direction pointing to the central axis of the fixed ring 10 under the driving of the connecting column 14, thereby reducing the distance between the plurality of paint spraying nozzles 12. At the same time, the upward displacement of the connecting column 14 causes the compression of the buffer spring 13 under stress, thereby completing the adjustment of the plurality of paint spraying nozzles 12, and achieving the effect of quickly adjusting the distance between the paint spraying nozzles 12 to adapt to the paint spraying needs of aluminum wires of different diameters. When it is necessary to increase the distance between the paint spraying nozzles 12, the output end of the electric push rod 26 is retracted, and the above movement process is reversed.

[0038] Reference Figure 4 and Figure 5 The roller assembly comprises a bearing column 17 made of metal material, which serves to support the aluminum wire roll or storage roll, so that it can rotate under the driving of the driving motor 16 to realize the unwinding or winding operation of the aluminum wire. The side wall of the bearing column 17 is provided with a fixed plate 15 fixedly connected at the top of the bottom plate 1 to provide a stable mounting base for the bearing column 17, so as to ensure that the bearing column 17 will not shake during work. The side wall of the fixed plate 15 is fixedly connected with the driving motor 16, and the output end of the driving motor 16 is fixedly connected with the side wall of the bearing column 17 to provide power for the rotation of the bearing column 17, so that the bearing column 17 can rotate at a set speed and direction. The inside of the bearing column 17 is slidably connected with a movable inner column 18 made of aluminum alloy, which serves to separate and lock with the bearing column 17 when disassembling the storage roll or other operations. The inside of the movable inner column 18 is slidably connected with a connecting rod 20 for connecting the button 19 and the conical block 21 to transfer the displacement force of the button 19 so that the conical block 21 can move synchronously. One end of the connecting rod 20 is fixedly connected with the button 19 made of plastic, and the surface thereof is treated with anti-skid treatment for facilitating the operation of the staff. The button 19 serves to provide an operation interface for the staff, and the unlocking action is triggered by pressing the button 19. The other end of the connecting rod 20 is fixedly connected with the conical block 21, which is in the shape of a cone and serves to control the position of the locking column 23 by its own displacement to realize the unlocking and locking of the movable inner column 18 and the bearing column 17. The bottom of the button 19 and the conical block 21 is provided with a reset spring 22, which functions to provide a restoring force after the displacement of the button 19 and the conical block 21 so that they can return to the initial position for the next operation. One end of the reset spring 22 is fixedly connected at the top of the movable inner column 18, and the other end thereof is fixedly connected at the bottom of the button 19 and the conical block 21, respectively. The outer wall of the conical block 21 is provided with a plurality of locking columns 23, which are slidably connected inside the movable inner column 18. The locking columns 23 are distributed in a circumferential manner. The locking columns 23 serve to be inserted into the inside of the bearing column 17 in the normal working state to realize the locking of the movable inner column 18 and the bearing column 17, and to be moved and retracted into the inside of the movable inner column 18 to realize the unlocking of the movable inner column 18 and the bearing column 17 when disassembling the storage roll. The outer wall of the locking column 23 is fixedly connected with a limiting plate 24, which serves to limit the displacement range of the locking column 23. The outer wall of the locking column 23 is sleeved with a limiting spring 25, which functions to provide a restoring force to make the locking column 23 slide inward and retract into the inside of the movable inner column 18 when the locking column 23 loses the extrusion force of the conical block 21. One end of the limiting spring 25 is fixedly connected with the side wall of the limiting plate 24, and the other end thereof is fixedly connected with the inside of the movable inner column 18.

[0039] Specifically, after the wire is painted, when the worker needs to disassemble the storage roll, the worker presses button 19 towards the inside of the movable inner column 18. The inward displacement of button 19 causes the conical block 21 to move synchronously via connecting rod 20. Since the two ends of connecting rod 20 are fixedly connected to button 19 and conical block 21 respectively, when button 19 moves, connecting rod 20 also moves, thereby causing conical block 21 to move. At the same time, when conical block 21 moves downward, return spring 22 is gradually compressed, and elastic potential energy continuously increases. After conical block 21 moves downward, the contact position between the bottom outer wall of conical block 21 and locking post 23 changes, and locking post 23 is no longer subjected to... Under the lateral squeezing force, and then the restoring force of the limiting spring 25 on its outer wall, the locking post 23 slides inward. The limiting spring 25, which was previously compressed by the cone block 21, stored elastic potential energy. When the locking post 23 loses the squeezing force, the limiting spring 25 releases the elastic potential energy, pushing the locking post 23 to move. The locking post 23 finally retracts into the movable inner post 18, thus completing the unlocking of the bearing post 17 and the movable inner post 18. At this time, the staff can hold the storage roll and remove it from the movable inner post 18, thereby achieving the effect of quickly storing the sprayed wire and facilitating the staff to carry out subsequent sorting and processing work.

[0040] Working principle: when using the fine e name aluminum wire mold coating machine, first, the staff will be placed on the bottom plate 1 side of the load column 17, the storage volume is placed on the other side of the load column 17, then the aluminum wire through the protection box 2 and the dryer 3 and fixed on the storage volume, at this time, both sides of the drive motor 16 drive load column 17 rotation, one side of the line, one side of the line, the aluminum wire through the paint spraying device inside the protection box 2 and the drying device inside the dryer 3 paint spraying and drying operation, when the need to adjust the distance between the paint spraying device according to the thickness of the aluminum wire, to meet the different paint spraying requirements, at this time, the output end of the electric push rod 26 inside the protection box 2 pushes the connecting block 27 displacement, the displacement of the connecting block 27 drives the rotating ring 8 to rotate, the rotating ring 8 rotates and makes the plurality of inclined groove 9 inside it also displacement, so that the bottom column 11 under the influence of the slope of the inclined groove 9 sliding, and then make the bottom column 11 upward displacement, through the connecting column 14 push the paint spraying nozzle 12 displacement, at the same time, also make the buffer spring 13 compression, so as to complete the adjustment of the plurality of paint spraying nozzle 12, so as to achieve the effect of quickly adjusting the distance between the paint spraying nozzle 12 to meet the different diameter of the aluminum wire paint spraying requirements, when the wire paint spraying is finished, the staff need to disassemble the storage volume, at this time, the staff manually press the button 19, the inward displacement of the button 19 through the connecting rod 20 drives the conical block 21 also displacement, at the same time, the displacement of the conical block 21 makes the reset spring 22 compression, when the conical block 21 displacement, the locking column 23 which is inserted into the inside of the load column 17 under the extrusion of the bottom wall of the conical block 21, at this time, the lateral extrusion force is lost, and then under the recovery force of the limiting spring 25 on its outer wall, slide inward, retract inside the movable inner column 18, so as to complete the unlocking of the load column 17 and the movable inner column 18, and then the staff can take down the storage volume, so as to achieve the effect of quickly storing the finished wire.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
