In order to ensure that fluorocarbon powder coating can be evenly coated on the surface of the workpiece, the design and performance of the coating device are crucial.

[0045] In the embodiment of the present invention, the movement direction of the rack 503 is controlled by the contact between the rack 503 and the extrusion plate 608, thereby controlling the rotation direction of the driving gear 502, and then controlling the adjustment rod 205 to rotate, controlling the rotation of the adjustment cone 2, and selecting a suitable spray port to complete the spraying.

[0046] Reference Figure 1-Figure 17 Specifically, in the embodiment of the present invention, the driving assembly includes a fixed frame 607, a ball slider 604 is fixedly installed on one side surface of the fixed frame 607, a screw rod 602 is rotatably connected to the inner wall of the ball slider 604, a moving frame 601 is installed on the outer side surface of the screw rod 602, an extrusion plate 608 is slidably connected to the one side surface of the moving frame 601, a spraying equipment housing 6 is installed on the bottom end surface of the moving frame 601, a driving motor 603 is installed inside the spraying equipment housing 6, a transmission disc 605 is fixedly installed on the outer side surface of the screw rod 602, and a transmission track 6 is movably installed on the outer side surface of the transmission disc 605 06, the inner wall of the fixed frame 607 is fixedly connected to the spray gun housing 1, the outer side of the ball slider 604 is in active contact with the inner wall of the mobile frame 601, and the mobile frame 601, the screw rod 602 and the transmission plate 605 are each provided with a plurality of screw rods 602 and the transmission plate 605, and are distributed in a linear array on the top surface of the spray equipment housing 6, and each adjacent screw rod 602 and the transmission plate 605 are connected by a transmission track 606, and the output end of the drive motor 603 is fixedly connected to one end of its screw rod 602, and the extrusion plate 608 is two equidistantly distributed on one side surface of the mobile frame 601, and the extrusion plate 608 is in active contact with the rack 503.

[0047] In the embodiment of the present invention, the drive motor 603 drives the screw rod 602 to rotate, so that the ball slider 604 slides up and down on the screw rod 602, driving the fixed frame 607 to move synchronously, and the transmission plate 605 and the transmission track 606 are used to realize the synchronous operation of adjacent spraying devices to ensure the quality of spraying.

[0048] Specific use process: when the fluorocarbon powder coating uniform coating device is needed, hold the nozzle 3 and align the inner wall of the nozzle 3 with the interface 101. After the alignment is completed, plug the two into each other, hold the nozzle 3 and rotate it, and fix the nozzle 3 and the interface 101 to each other through the threaded movable rotation connection. When the nozzle 3 is rotated and installed, it will move along the interface 101. At this time, the inner wall of the nozzle 3 will be aligned with the outer surface of the adjustment cone 2, and as the nozzle 3 moves, the nozzle 3 will adjust the adjustment cone 2. The cone 2 is squeezed inwards, and the adjusting cone 2 will shrink toward the inside of the connecting pipe 105 when being squeezed, and a limiting ring 201 is installed on the outer surface of the adjusting cone 2. As the adjusting cone 2 moves, the limiting ring 201 will squeeze the squeezing spring 203, and the adjusting cone 2 will be squeezed by the compressed squeezing spring 203, so that the adjusting cone 2 can be tightly attached to the inner wall of the nozzle 3. When the nozzle 3 is installed, the spray gun housing 1 is installed on the inner wall of the fixing frame 607 to realize the assembly of the spray gun.

[0049] One end of the delivery pipe 106 is connected to a container containing fluorocarbon powder coating, and an air compressor is used to provide power for the spray gun. When the fluorocarbon powder coating needs to be sprayed, the air compressor and the drive motor 603 are started. When the drive motor 603 is started, it will drive the screw rod 602 connected to its output end to rotate, and a ball slider 604 is installed on the outer surface of the screw rod 602. Therefore, when the screw rod 602 rotates, the ball slider 604 will extend the screw rod 602 to move up and down, thereby providing up and down movement force for the spray gun. When the air compressor is started, the fluorocarbon powder will be delivered to the delivery pipe 106. Internally, the delivery pipe 106 is interconnected with the interior of the connecting pipe 105. At this time, the fluorocarbon powder will move to the inner wall of the connecting pipe 105, and move from the inside of the connecting pipe 105 to the inner wall of the connecting groove 202, so that when the fluorocarbon powder moves along the inner wall of the connecting groove 202 to its end, it enters the inner wall of the straight-outlet nozzle 302, and finally the fluorocarbon powder is sprayed out by the straight-outlet nozzle 302. Because the output end of the high-voltage generator 104 extends to the inside of the connecting pipe 105, the high-voltage generator 104 provides electrostatic charge for the powder particles when the spray gun is started, so that it can be adsorbed to the surface of the workpiece to achieve the coating function.

[0050] When the spray gun moves to its end along the screw rod 602 due to the drive of the ball slider 604, the top or bottom surface of the rack 503 will contact with the extrusion plate 608. Because the spray gun drives the rack 503 to move, the extrusion plate 608 will squeeze the rack 503. At this time, the squeezed rack 503 will move on the inner wall of the slide groove 501. The rack 503 and the driving gear 502 are meshed with each other. Therefore, when the rack 503 moves, it will push the driving gear 502 to rotate. At this time, the driving gear 502 will drive the adjusting rod 205 to rotate on the inner wall of the control box 5. The adjusting rod 205 is fixedly connected to the adjusting cone 2. Therefore, the rotating adjusting rod 205 will drive the adjusting cone 2 to rotate. When the adjusting cone 2 rotates, the switching hole 204 opened on its outer surface will rotate to one end of the first angle nozzle 303 or the second angle nozzle 301, so that the connecting groove 2 The inner wall of 02 is connected with the straight nozzle 302 and the first angle nozzle 303 or the second angle nozzle 301 at the same time. When the fluorocarbon powder is sprayed, a certain amount of fluorocarbon powder will be sprayed out from the end of the first angle nozzle 303 or the second angle nozzle 301. Because the first angle nozzle 303 and the second angle nozzle 301 have a bending angle, when the spray gun moves upward, the first angle nozzle 303 activated at this time will cause the sprayed fluorocarbon powder to present an upward angle due to its own bending angle, thereby realizing spraying on the bottom surface of the workpiece. When the spray gun moves downward, the second angle nozzle 301 will spray the top surface of the workpiece, thereby realizing sufficient spraying on the surface of the object. The extrusion plate 608 is slidably fixed to the side surface of the mobile frame 601 by bolts. When it is necessary to adjust the trigger height of the spray gun switch, it is only necessary to adjust the height of the extrusion plate 608 on the mobile frame 601 to realize the adjustment function.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
