[0047] The spraying assembly 2 includes a rotating rod 201 hinged on the rotating rod 109, a protective rod 202 is fixed at one end of the rotating rod 201, a spiral rod 203 is hinged inside the protective rod 202, and a sprayer 204 is threadedly connected to the side of the spiral rod 203. One end of the rotating rod 201 is fixed to the bottom end of the rotating rod 109. When the rotating rod 109 rotates, it drives the rotating rod 201 to rotate. At the same time, a protective rod 202 is installed at the bottom of one end of the rotating rod 201. The side of the protective rod 202 is U-shaped and is hinged with the spiral rod 203 inside. At the same time, the side of the sprayer 204 fits in the protective rod 202. When the spiral rod 203 rotates, the sprayer 204 is lifted up and down under the force of the internal thread connection with the sprayer 204, so as to achieve the effect of adjusting the height position of the spraying.

[0048] The fixing assembly 3 includes a rotating disk 301 hinged on a stable base plate 101, a limiting slide groove 302 is provided on the rotating disk 301 in a cross direction, a moving block 304 is connected in the limiting slide groove 302, a stable box 305 is fixed on the moving block 304, a bent rod 308 is sleeved in the stable box 305, a fixed plate 309 is fixed at one end of the bent rod 308, and a clamping plate 310 is fixed on the side of the fixed plate 309. The rotating disk 301 can rotate freely. At the same time, when the moving block 304 slides back and forth in the limiting slide groove 302, the clamping plate 310 installed on the top moves toward the periphery or toward the center position, thereby achieving the effect of clamping or unfolding the metal product. At the same time, during the clamping process, the clamping plate 310 is concave after being subjected to force. At this time, the fixed plates 309 at both ends pull the bent rod 308 to move outward, thereby achieving the effect of clamping round or irregular metal products.

[0049] The working principle of the metal product spraying device proposed in this embodiment is as follows: when in use, by placing the metal object on the rotating disk 301, the output end of the motor 311 is controlled to rotate clockwise, so that under the meshing force between the gear ring 313 and the bevel gear 314, the bevel gear 314 drives the threaded rod 303 to rotate counterclockwise in the opposite direction. At this time, under the action of the threads between the threaded rod 303 and the inside of the moving block 304, the moving block drives the top stabilizing box 305 and the clamping plate 310 to move toward the middle until the clamping plate 310 is clamped on the outside of the metal product. When fixing the cylindrical metal product, first control the stabilizing box 305 and the clamping plate 310 to be concentrated in the middle, place the cylindrical metal product on the rotating disk 301, and then control the gear ring 313 to rotate in the opposite direction, so that the moving block 304 drives the stabilizing box 305 and the clamping plate 310 to rotate counterclockwise. 0 is unfolded outward and clamped on the inner side of the cylindrical metal product. After the clamping is completed, the driving motor 104 is controlled to operate so that its output end drives the driving gear 106 to rotate, and drives the transmission gear 107 to rotate through the transmission crawler 108 sleeved on the side, so that the fixed rotating rod 109 drives the rotating rod 201 to rotate around the side of the metal product, and the liquid storage cylinder 110 is controlled to input the internal pigment into the sprayer 204 through the connecting pipe 207. After the pigment forms pressure in the sprayer 204, it is sprayed from the installed atomizing nozzle 205 to the side of the fixed metal product, and the driving motor 208 is controlled to operate so that its output end drives the spiral rod 203 to rotate. Under the force of the connection between the side thread of the spiral rod 203 and the internal thread of the sprayer 204, the sprayer 204 gradually moves up and down to spray the metal product comprehensively.

[0050] Furthermore, a driving box 105 is fixed on the top plate 103 of the device, a driving gear 106 and a transmission gear 107 are hinged in the driving box 105, and a transmission track 108 is sleeved on the side, and one end of a rotating rod 109 is fixed on the transmission gear 107;

[0051] More specifically, the two gears are respectively installed at two ends of the driving box 105, and the sides are sleeved in the same transmission track 108. When the driving gear 106 rotates, the transmission track 108 drives the transmission gear 107 to rotate synchronously.

[0052] Furthermore, a driving motor 104 is fixed to the bottom of the device top plate 103, and the output end of the driving motor 104 passes through the device top plate 103 and is fixed to the driving gear 106;

[0053] More specifically, the output end of the driving motor 104 has a bidirectional rotation function. When it is powered on, the output end drives the driving gear 106 to rotate.

[0054] Furthermore, a liquid storage cylinder 110 is installed on the driving box 105, and a mounting interface 206 is provided on the sprayer 204. A connecting tube 207 is fixed on the mounting interface 206, and one end of the connecting tube 207 is installed on the interface of the liquid storage cylinder 110;

[0055] More specifically, the liquid storage cylinder 110 is used to store the paint for spraying and is provided with an interface, which is installed at one end of the connecting tube 207 so that the paint inside can be input into the sprayer 204 through the connecting tube 207 .

[0056] Furthermore, a plurality of atomizing nozzles 205 communicating with the interior are equidistantly mounted on the side of the sprayer 204;

[0057] More specifically, after the paint enters the sprayer 204 and forms pressure, the paint is atomized and sprayed out through the atomizing nozzle 205, so that the metal product can be sprayed evenly.

[0058] Furthermore, a threaded rod 303 is hinged in the limiting slide groove 302, and the threaded rod 303 is threadedly connected in the moving block 304;

[0059] More specifically, the side of the moving block 304 fits in the limiting slide groove 302 and is threadedly connected to the side of the threaded rod 303. When the threaded rod 303 rotates clockwise or counterclockwise, the moving block 304 moves back and forth in the limiting slide groove 302 under the action of the internal thread connection with the moving block 304, so that the stabilizing box 305 installed on the top drives the clamping plate 310 to move, thereby achieving the function of clamping and fixing the metal product.

[0060] Furthermore, a center rod 306 is fixed in the stabilizing box 305, and tension springs 307 are fixed at both ends of the center rod 306, and one end of the tension spring 307 is fixed to one end of the bent rod 308;

[0061] More specifically, the tension spring 307 has a contraction force, which is used to pull the bent rod 308 inward, so that the clamping plate 310 is horizontally attached to the side of the metal product. When clamping the circular metal product, the clamping force causes the clamping plate 310 to be concave, so that it can be tightly attached to the side of the circular metal product under the action of elasticity, thereby achieving the function of clamping and fixing metal products of different shapes.

[0062] Furthermore, a motor 311 is fixed on the stable base plate 101, and a connecting rod 312 is fixed to the output end of the motor 311, and one end of the connecting rod 312 is fixed to the inner side of the gear ring 313, and the gear ring 313 is sleeved in the stable base plate 101;

[0063] More specifically, when the motor 311 is in operation, its output end drives the connecting rod 312 to rotate, so that the gear ring 313 rotates. At the same time, a groove body that matches the gear ring 313 is opened in the stable bottom plate 101 to improve the rotation stability of the gear ring 313.

[0064] Further, a bevel gear 314 is fixed to one end of the threaded rod 303 and meshes with the side of the gear ring 313;

[0065] More specifically, the outer side of the gear ring 313 is inclined and meshes with the bevel gear 314. When the gear ring 313 rotates, the four threaded rods 303 rotate synchronously through the force of the meshing of the teeth.

[0066] Furthermore, a limit button 3031 is fixed to the other end of the threaded rod 303 and is attached to the side of the moving block 304;

[0067] More specifically, the diameter of the limit button 3031 is larger than the diameter of the threaded rod 303. When the moving block 304 moves toward the front end of the threaded rod 303, after being attached to the side of the limit button 3031, it prevents the moving block 304 from detaching from the side of the threaded rod 303.
