[0034] Then, the right end of the slide rod 6 is fixedly installed with a connecting rod 8, the right end of the connecting rod 8 is fixedly installed with a mounting plate 13, the right side of the mounting plate 13 is fixedly installed with a vertical rod 14 of a transverse structure, and it should be noted that in the process of use, the slide rod 6 will move synchronously with the connecting rod 8, at this time, the connecting rod 8 will move synchronously with the fixedly connected mounting plate 13, and the moving direction and distance can be adjusted by the gear 11, because in the process of use, the gear 11 is engaged with the tooth groove 7 on the outer side of the slide rod 6 through the second through hole 3, so the interval of the slide rod 6 can be adjusted.

[0035] Secondly, the mounting plate 13 will move synchronously with the vertical rod 14 in the process of movement, at this time, the left lower end surface of the vertical rod 14 is fixedly installed with a first motor 19, and the output shaft of the first motor 19 is fixedly installed with a notched wheel 20 through the vertical rod 14 and above the vertical rod 14, as shown in Figure 4 .

[0036] And a through sliding groove 15 is formed on the right side upper part of the vertical rod 14, and a sliding plate 17 is slidably installed in the through sliding groove 15, as shown in Figure 4 .

[0037] The left side of the sliding plate 17 protrudes inwardly and outwardly, and the protruding right side is fixedly installed with a spring 16, and the spring 16 is fixedly installed on the upper right side of the vertical rod 14, as shown in Figure 4 . And a rotating wheel 18 is rotatably installed on the left side upper part of the sliding plate 17.

[0038] In the process of use, the sliding plate 17 will move synchronously with the first motor 19 and the notched wheel 20, at this time, the vertical rod 14 will move synchronously with the sliding plate 17, and in the process of movement, the first motor 19 is started At this time, the output shaft of the first motor 19 will rotate with the notched wheel 20, and the circumferential surface of the notched wheel 20 and the rotating wheel 18 is in a state of abutting, and because of the special structure of the notched wheel 20, in the process of operation, the notched wheel 20 will make the sliding plate 17 slide in the through sliding groove 15 through the rotating wheel 18, as shown in Figure 4 .

[0039] In the process of use, the vertical rod 14 moves with the first motor 19, the first motor 19 moves with the notched wheel 20, the vertical rod 14 moves with the sliding plate 17, and the sliding plate 17 moves with the spring 16 and the rotating wheel 18.

[0040] Further cooperating with the operation of the notched wheel 20, the sliding plate 17 can move synchronously with the subsequent operation structure.

[0041] The middle upper end surface of the slide plate 17 is fixedly installed with a second motor 21, the output shaft of the second motor 21 penetrates through the slide plate 17, and two horizontal groove wheels 22 are eccentrically fixedly installed on the lower end surface of the slide plate 17, as shown in Figure 4 .

[0042] Then, the outer circumferential surface of the groove wheel 22 is recessed, and a connecting ring 23 is rotatably installed in the recessed structure, and a driving rod 24 is fixedly installed on the outer circumferential surface of the connecting ring 23, as shown in Figure 7 .

[0043] Then, a horizontally structured shell 26 is fixedly installed on the right side of the lower end surface of the slide plate 17, the left side to the inside of the shell 26 is a hollow structure, and the right end is a circular truncated cone structure, and then a slide column 25 is slidingly installed in the inside of the shell 26, the left end of the slide column 25 is located outside the shell 26, and the outer side of the slide column 25 is a U-shaped structure, and a vertical circular rod is fixedly installed in the inside of the U-shaped structure, and the outer circumferential surface of the circular rod is in a rotating connection state with the right end of the driving rod 24, as shown in Figure 8 .

[0044] In use, the second motor 21 is started, the output shaft of the second motor 21 rotates with the groove wheel 22, the groove wheel 22 rotates with the connecting ring 23, and because the connecting ring 23 and the groove wheel 22 are in a rotating connection state, the driving rod 24 fixedly installed on the circumferential surface of the connecting ring 23 also moves left and right in use, and the driving rod 24 moves left and right with the slide column 25 sliding horizontally in the inside of the shell 26, and it should be noted that a sealing ring can be used between the slide column 25 and the shell 26 to avoid leakage.

[0045] Then, a nozzle 28 is fixedly installed on the right end of the shell 26, and the nozzle 28 is a pipe nested together with three different diameters, so that in use, the length of the nozzle 28 can be adjusted manually, so that the length of the whole nozzle 28 can be changed, as shown in Figure 8 .

[0046] Further, a plurality of nozzles 29 are fixedly installed on the outer circumferential surface of the nozzle 28, and then a material box 27 is fixedly installed on the right upper end of the slide plate 17, and a connecting pipe is fixedly installed on the lower end of the material box 27, and the lower end of the connecting pipe is fixedly installed on the outer circumferential surface of the shell 26, so that under the action of the connecting pipe, the material in the inside of the material box 27 can fall into the inside of the shell 26, then enter the inside of the nozzle 28 under the action of the slide column 25, and finally be sprayed out through the nozzles 29.

[0047] In use, the second motor 21 is started, the output shaft of the second motor 21 rotates with the groove wheel 22, the groove wheel 22 rotates with the connecting ring 23, the connecting ring 23 can rotate under the action of the drive rod 24, it needs to be explained that when the drive rod 24 slides in the inside of the shell 26, the sliding distance cannot be greater than the length of the shell 26, so as to avoid the slide column 25 from sliding out of the shell 26.

[0048] Secondly, during operation, the liquid material in the tank 27 will gradually fall into the inside of the shell 26, at this time, the slide column 25 can quickly extrude the liquid during movement, and because the right end of the shell 26 is a circular table structure, the gas-liquid can quickly enter the inside of the nozzle 28 under the action of the internal pressure, and then be sprayed out through the nozzle 29.

[0049] Because the sliding distance of the slide column 25 is equal each time, during continuous movement, the slide column 25 can uniformly push the liquid material into the nozzle 28, and this uniform pushing design ensures that the paint spraying device can provide stable and continuous paint spraying effect during work, avoiding uneven or interrupted paint spraying problems. In addition, the equidistant sliding of the slide column 25 also helps to control the thickness of the paint spraying, making the paint spraying layer more uniform and consistent, improving the paint spraying quality of automobile parts.

[0050] At the same time, because of the circular table structure design of the shell 26, the liquid material can quickly and smoothly flow to the nozzle 28 under the action of the internal pressure, further enhancing the paint spraying efficiency, which not only optimizes the paint spraying process, but also reduces material waste, improving the overall work efficiency.

[0051] Working principle: Firstly, the operator can rotate the adjusting rod outside the left front end vertical plate 9, the adjusting rod can rotate the drive wheel 10, the drive wheel 10 rotates the caterpillar belt 12 synchronously, at this time, the caterpillar belt 12 drives the right gear 11 to rotate, because the gear 11 and the tooth groove 7 on the slide rod 6 are meshed with each other, when the gear 11 rotates, it drives the slide rod 6 to slide left and right in the cavity slide rod 1, and moves left and right, so as to realize uniform paint spraying of automobile parts subsequently.

[0052] At this time, the connecting rod 8 will move synchronously with the fixedly connected mounting plate 13, and the moving direction and distance can be adjusted by the gear 11, the mounting plate 13 moves synchronously with the vertical rod 14.

[0053] The vertical rod 14 drives the first motor 19, the first motor 19 drives the notch wheel 20, and the vertical rod 14 drives the slide plate 17, the slide plate 17 drives the spring 16 and the rotating wheel 18.

[0054] At this time, the output shaft of the first motor 19 rotates with the notched wheel 20, and the notched wheel 20 and the circumferential surface of the rotating wheel 18 are in a state of abutment. Due to the special structure of the notched wheel 20, the notched wheel 20 can make the sliding plate 17 slide in the inside of the through sliding groove 15 through the rotating wheel 18 during operation.

[0055] The second motor 21 is started, and the output shaft of the second motor 21 rotates with the grooved wheel 22. The grooved wheel 22 rotates synchronously with the connecting ring 23. Since the connecting ring 23 and the grooved wheel 22 are in a rotating connection state, the driving rod 24 fixedly installed on the circumferential surface of the connecting ring 23 also moves left and right during use. The driving rod 24 moves left and right, and the sliding column 25 moves horizontally in the inside of the shell 26. It should be noted that a sealing ring can be used between the sliding column 25 and the shell 26 to prevent leakage.

[0056] The length of the spray pipe 28 can be adjusted manually by the operator, so that the length of the spray pipe 28 can be changed.

[0057] During operation, the liquid material in the tank 27 falls into the inside of the shell 26. At this time, the sliding column 25 can quickly extrude the liquid during movement. Since the right end of the shell 26 is a circular table structure, the gas-liquid can quickly enter the inside of the spray pipe 28 under the action of internal pressure, and then be sprayed out through the spray port 29.

[0058] Since the sliding distance of the sliding column 25 is equal each time, the sliding column 25 can uniformly push the liquid material into the spray pipe 28 during continuous movement.

[0059] At the same time, due to the circular table structure design of the shell 26, the liquid material can quickly and smoothly flow to the spray pipe 28 under the action of internal pressure.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments can be modified, or some or all of the technical features can be replaced by equivalent replacements. The modifications or replacements do not change the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
