[0030] Reference Figures 1 to 14 The embodiments of this utility model will be further described below.

[0031] A powder coating gun control structure includes a spray box 1 and a spray gun 12. The spray box 1 has a spraying cavity, and a controller is provided on the spray box 1. A spray frame 13 is rotatably arranged in the spraying cavity. The spray gun 12 is arranged in the spray box 1 with its output end facing the spraying cavity, and can spray parts. The spray box 1 is provided with a drive component 2 that connects to the spray gun 12. The drive component 2 controls the opening and closing of the spray gun 12. The drive component 2 includes a rotating component 21, a locking connecting block, and a first motor 22. A fixing groove for fixing the spray gun 12 is formed on the locking connecting block, which can easily fix the spray gun 12 and the first motor 22, so that the drive component 2 and the spray gun 12 form a whole and can be moved together. The drive component 2 is connected to the controller through a circuit, and the controller can control the drive component 2.

[0032] The rotating component 21 includes a first rotating wheel and a rotating belt 23. The first rotating wheel is connected to the output shaft of the first motor 22 and rotates accordingly. Engaging teeth are evenly arranged on the inner side of the rotating belt 23. The first rotating wheel has recessed grooves that mate with the engaging teeth. After the engaging teeth engage with the first rotating wheel, the first motor 22 controls the rotation of the rotating belt 23. The spray gun 12 has an adjusting valve core at its output end. This adjusting valve core serves as the rotating part or adjusting end; its rotation linearly changes the opening of the output end of the spray gun 12, thereby controlling the spray flow rate. In this embodiment, the adjusting valve core can be made with the same structure as the first rotating wheel (see attached diagram). Figure 9 This causes the regulating valve core to engage with the rotating belt 23, enabling the first motor 22 to control the spraying amount at the output end of the spray gun 12 via the belt.

[0033] Alternatively, the first rotating wheel can be configured as a gear structure, and the regulating valve core can also be configured as a gear structure to achieve the same effect. The connection between the regulating valve core and the first motor 22 can be changed to achieve the effect of regulating the spray gun.

[0034] The drive component 2 receives an electrical signal from the controller via the first motor 22, driving the rotating component 21 to rotate the regulating valve core. The controller, through programming, can precisely control the rotation angle and duration of the first motor 22, thereby converting the motor's motion into precise, programmable control of the spray flow rate, achieving segmented quantitative spraying.

[0035] The spray box 1 is equipped with a sealing cover 3 that seals the spraying chamber. The sealing cover 3 has an observation port 31 that connects to the spray gun 12, which facilitates observation of the internal parts processing.

[0036] A locking block is provided on the spray box 1, and a locking part 4 protrudes from the locking block. The locking part 4 is a protrusion integral with the spray box 1. A first rotating block 41 and a second rotating block 42 are rotatably mounted on the locking part 4. A third rotating block 431 is rotatably connected to the other end of the first rotating block 41 and the second rotating block 42. A handle part 432 extends from the third rotating block 431. A clamping rod 43 is also provided on the second rotating block 42. A clamping block 44 is provided on the clamping rod 43. By rotating the handle part 432, the clamping block 44 can be driven to clamp the sealing cover 3 or separate from the sealing cover 3 (see attached). Figure 10 , 11 The above structure makes it easier to lock the sealing cover 3, facilitates operation during processing, and makes it easy to fix and open.

[0037] A support frame 45 is movably connected to the spray box 1. An adjusting component for the adjusting drive component 2 is provided on the support frame 45. A connecting rod is provided on the sealing cover 3. The connecting rod rotates and is positioned at the lower edge of the observation port 31. The drive component 2 includes a fixing block fixed to the connecting rod. The fixing block is fixed to the locking connecting block (that is, the drive component 2 and the spray gun 12 are connected as a whole to the fixing block and can change the orientation of the output end of the spray gun 12 as the connecting rod rotates).

[0038] The adjusting component includes a first gear 5, an adjusting rod 51, a locking rod 52, and a first rack 53. A first rotating part 57 is formed at one end of the fixing block. A second rotating part 572, which engages with the adjusting rod 51, is formed on the adjusting rod 51. The first rack 53 slides on the support frame 45 and meshes with the first gear 5. A fixing groove 531 is recessed on the first rack 53. A fixing part 532, which engages with the adjusting rod 51, is provided at the other end of the adjusting rod 51. A limiting protrusion protrudes from the fixing part 532. The fixing groove 531 has a corresponding limiting recess, and both are provided in upper and lower sets to ensure stability. The fixing groove 531 also has a connecting fixing part 53. The reset spring 535 of 2 facilitates reset. The first rotating part 57 and the second rotating part 572 are both provided with a first locking groove 541 and cooperate with each other to form a second locking groove 54. The locking rod 52 passes through the first rotating part 57 and the second rotating part 572 and restricts their separation. One end of the locking rod 52 is also provided with a locking block 55 that engages with the second locking groove 54, and the other end is provided with a limiting end 555. The limiting end 555 effectively prevents the locking rod 52 from disengaging. The first gear 5 is provided with a rotating disk 56, and the rotating disk 56 is located outside the support frame 45. By rotating the rotating disk 56, the first gear 5 can be driven to rotate.

[0039] When the pitch angle of the spray gun 12 needs to be adjusted, the operator pulls the locking lever 52 outward, causing the locking block 55 at its end to disengage from the second locking groove 54 formed by the first rotating part 57 and the second rotating part 572. At this time, the fixing block (and its driving component 2 and the entire spray gun 12) can rotate freely around the axis of the connecting rod. After observing through the observation port 31 and manually adjusting to the desired angle, the locking lever 52 is released, and the return spring 535 pushes the locking lever 52 back to its original position, causing the locking block 55 to re-engage into the second locking groove 54, thereby locking the angle of the spray gun 12.

[0040] When it is necessary to adjust the left and right horizontal position of the spray gun 12, the operator rotates the rotating disk 56 located outside the support frame 45, which drives the first gear 5 to rotate. The first gear 5 drives the first rack 53, which meshes with it, to slide laterally along the support frame 45. Since the fixing part 532 at one end of the adjusting rod 51 is engaged in the fixing groove 531 of the first rack 53, the adjusting rod 51 will drive the second rotating part 572 at its other end and the fixing block (and the entire spray gun 12) that is inserted into the second rotating part 572 to move laterally together, so as to realize continuous and precise adjustment of the left and right position of the spray gun 12.

[0041] The controller on the spray box 1 can be used to control the input time and spraying amount. A support block is provided inside the spraying chamber, and a spraying hole 14 is provided on the spraying frame 13 to allow communication between the outside and the inside of the spraying frame 13. A rotating wheel is provided inside the spraying chamber to support the rotation of the spraying frame 13 and ensure uniform spraying. A rotating groove 15 is provided at one end of the spraying frame 13 to engage with the support block.

[0042] The operation method is as follows:

[0043] Step 1: Rotate the spraying frame and then place the product into the spraying chamber;

[0044] Step 2: Input the quantity and size of the products into the controller to perform the spraying process. The specific steps are as follows:

[0045] Step 1: Calculate the total processing time into segments based on the product size and quantity, and input the amount of paint to be applied in each segment into the controller;

[0046] Step 2: Adjust the spray gun angle and left / right distance using the rotating disc and adjusting lever, then start the controller;

[0047] Step 3: The controller controls the rotation of the spraying chamber;

[0048] Step 4: Infrared sensing of product temperature status;

[0049] Step 5: The controller controls the motor to rotate based on the data, thereby starting the spray gun;

[0050] Step 6: The controller repeatedly starts according to the segmented time intervals to segment the product and spray it in the required amount;

[0051] Step 3: Use infrared sensors to detect the product's temperature and then turn off the device;

[0052] Step 4: Rotate the spraying rotating frame and sealing cover to remove the product.
