[0041] When the spraying device is in use, the workpiece is placed on the central surface of the workbench 4, and then the spraying device 3 can extract the spraying material inside the material box 2, and the spraying device 3 transports the spray material to the inside of the ejector 5, and then the spray material is sprayed out through the rotation and diversion of the ejector 5 to achieve spraying of the workpiece. When the workpiece is placed at the central position of the upper surface of the workbench 4, the motor is started, and the output end of the motor can drive the large gear 404 to rotate. The rotation of the large gear 404 can drive the three sets of rack blocks 403 to engage and move. When the rack block 403 engages and moves, it can drive the first sliding block 405 to move. When the first sliding block 405 moves, it can slide through the guide groove 402. When the first sliding block 405 slides, it can drive the extrusion block 406 to move. The three extrusion blocks 406 can move to the side of the workpiece for extrusion positioning. The three extrusion blocks 406 will move synchronously, which improves the accuracy and stability of the spraying device when clamping the workpiece.

[0042] Embodiment 2: Figure 4 and Figure 6 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the spraying device is inconvenient to turn over and roll the workpiece, which affects the spraying efficiency, a rolling mechanism is disclosed on the basis of the first embodiment:

[0043] The rolling mechanism includes a first gear 408, which rotates inside the first rotating groove 407. A one-way bearing is rotatably installed between the first gear 408 and the large gear 404. An external block 410 is connected to the top center of the workbench 4. A friction wheel 411 rotates inside the external block 410. A first bevel gear 412 is fixed to one end of the friction wheel 411. A second bevel gear 413 is meshed and connected to the side of the first bevel gear 412. The second bevel gear 413 penetrates and rotates inside the penetration groove 424. The penetration groove 424 is penetrated and opened inside the external block 410. A second gear 409 is fixed to the bottom end of the second bevel gear 413. The second gear 409 is meshed and connected to the side of the first gear 408.

Four movable balls 414 are arranged inside the extrusion block 406.

[0044] When the spraying device places a workpiece on the upper surface of the workbench 4, the workpiece is placed inside the external block 410. After the workpiece is placed, the bottom of the workpiece can contact the surface of the friction wheel 411. At this time, the motor is started in reverse, and the motor output end can drive the large gear 404 to rotate in the opposite direction. When the large gear 404 is reversed, it can drive the first gear 408 to rotate through the one-way bearing. When the first gear 408 rotates, it can drive the second gear 409 to mesh and rotate. When the second gear 409 meshes and rotates, it can rotate through the first rotating groove 407. When the second gear 409 rotates, it can drive the second bevel gear 413 to rotate. The second bevel gear When 413 rotates, it can drive the first bevel gear 412 on the top to engage and rotate. When the first bevel gear 412 engages and rotates, it can rotate through the through groove 424. When the first bevel gear 412 rotates, it can drive the friction wheel 411 to rotate. When the friction wheel 411 rotates, it can drive the workpiece on the surface to rotate and roll through its own friction material. When the workpiece rolls, due to the extrusion force of the extrusion block 406, the workpiece will be squeezed by the movable ball 414. When the workpiece rolls, the movable ball 414 can roll inside the extrusion block 406. After the workpiece rolls, the position or angle can be adjusted, thereby improving the spraying efficiency of the spraying device.

[0045] Embodiment 3: Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the spraying device is difficult to adapt to workpieces of different sizes, on the basis of the first embodiment, a fine-tuning mechanism is disclosed:

[0046] The fine-tuning mechanism includes a positioning rod 416, which is fixed to the side of the extrusion block 406 close to the sliding rod 415. The sliding rod 415 and the positioning rod 416 are both inserted and slid inside the first sliding block 405. The positioning rod 416 has multiple sets of slots 417 on the upper and lower sides. The first sliding block 405 is provided with two sets of sliding slots 418 on the side away from the extrusion block 406. A second sliding block 419 is inserted and slid inside the sliding slot 418. The first sliding block 405 is connected to a rotating screw on the side close to the sliding slot 418. A rotating ring 420, a side of the rotating ring 420 close to the first sliding block 405 is symmetrically provided with an extrusion groove 421, a second sliding block 419 is slidably penetrated in the extrusion groove 421, a rotating block 422 is symmetrically fixed to the side of the rotating ring 420 close to the extrusion groove 421, the rotating block 422 is slidably penetrated in the second rotating groove 423, a spring is connected between the rotating block 422 and the second rotating groove 423, and the second rotating groove 423 is provided on the side of the first sliding block 405 close to the second sliding block 419;

[0047] When the workpiece processed by the spraying device is small, the extrusion block 406 may not reach the specified position, and the workpiece cannot be positioned, so that effective spraying cannot be performed. It is necessary to pull the extrusion block 406 toward the center direction of the workbench 4. When the extrusion block 406 is pulled, the sliding rod 415 and the positioning rod 416 can be driven to move. When the sliding rod 415 and the positioning rod 416 move, they can slide through the first sliding block 405. When the positioning rod 416 slides, the card slot 417 can be driven to move. When the extrusion block 406 slides to the specified position, the other groups of the card slot 417 can be moved to the side of the second sliding block 419. At this time, rotating the rotating ring 420 can drive the rotating block 422 to rotate. When the rotating block 422 rotates, it can slide through the second rotating groove 423. At the same time, when the rotating block 422 slides, the spring can generate a thrust on the rotating block 422, and the rotating block 422 slides. When the rotating ring 420 is in motion, the rotating ring 420 can rotate, and the rotating block 422 can drive the extrusion groove 421 to rotate when it rotates. When the extrusion groove 421 rotates, the inner wall can squeeze the second sliding block 419. When the second sliding block 419 is squeezed, it can slide through the sliding groove 418. After the second sliding block 419 slides into the inside of the slot 417, it can be engaged and positioned. After the rotating ring 420 is released, the rotating block 422 can be positioned under the action of the spring. After the rotating block 422 is positioned, it can prevent the rotating ring 420 from rotating arbitrarily, thereby improving the stability of the engagement between the second sliding block 419 and the slot 417. After the slot 417 is stable, it can drive the extrusion block 406 to be positioned. At this time, the position of the extrusion block 406 is closer to the center of the workbench 4 than before, thereby extruding and positioning smaller workpieces, thereby realizing the adjustment of the clamping distance of the spraying device.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
