[0033] like Figures 1 to 8 As shown, a high-efficiency automated CNC spraying machine comprises a machine frame 1, a multi-directional driving frame 2 is arranged on the rear side of the upper surface of the machine frame 1, a pumping pipe 301 is fixedly connected to the outer surface of the multi-directional driving frame 2, a feeding pipe 302 is arranged on the lower surface of the pumping pipe 301, a nozzle 6 is arranged at the end of the pumping pipe 301, a mixing component is arranged on the outer surface of the pumping pipe 301, a clearing component is arranged inside the pumping pipe 301, a unidirectional driving frame 7 is arranged on the side of the upper surface of the frame, a flip component is arranged on the outer surface of the unidirectional driving frame 7, a positioning component is arranged on the outer surface of the unidirectional driving frame 7, and a control console 10 is arranged at the front end of the machine frame 1, and the control console 10 can drive all components to run to realize automation;

[0034] The mixing component and the cleaning component are at the junction of the nozzle 6 and the pumping pipe 301. The pumping pipe 301 feeds the spray material from the feed pipe 302 into the mixing component. The operation of the mixing component will stir and vibrate the paint, break the centrifugal force in the stirring process, make the spray material stir more evenly, discharge the bubbles retained in the spray material, ensure the uniformity of the sprayed paint, and achieve the purpose of improving the spray quality of the object. The cleaning component is linked with the mixing component to clean the filter plate 501 back and forth, avoiding the missed particulate matter in the spray material from clogging the nozzle 6 and maintaining the patency of the nozzle 6. The positioning component can clamp objects of various shapes, improving the applicability of the device. The flipping component can flip the object 180 degrees, which is convenient for spraying the bottom of the object.

[0035] like Figure 2 and Figure 3As shown, the mixing assembly includes a box body 401 fixedly connected to the end of the pumping pipe 301, the outer surface of the box body 401 is fixedly connected to a motor 402, the driving end of the motor 402 is fixedly connected to a stirring rod 403, the outer surface of the stirring rod 403 is fixedly connected to a stirring ring 404, the outer surface of the stirring rod 403 is fixedly connected to a turntable 405, the outer surface of the turntable 405 is fixedly connected to a shifting block 406, the inner wall of the box body 401 is fixedly connected to a positioning rod 407, the outer surface of the positioning rod 407 is movably sleeved with a jacking pipe 408, and the jacking pipe 408 is fixedly connected to the outer surface of the jacking pipe 408. A convex block 409 is fixedly connected to the lower part of the outer surface of 8, the nozzle 6 is fixedly connected to the side of the box body 401 away from the pumping pipe 301, and the two sides of the box body 401 are respectively connected to the pumping pipe 301 and the nozzle 6, the stirring rod 403 is movably interspersed and arranged on the side of the box body 401, and one end of the stirring rod 403 away from the motor 402 is movably connected to the inner wall of the box body 401, and two stirring rings 404 are provided and symmetrically distributed about the midpoint of the stirring rod 403, and the two stirring rings 404 are arranged in a truncated cone shape, and the outer surface of the shifting block 406 abuts against the convex block 409;

[0036] The rotation of the driving end of the motor 402 drives the stirring rod 403 to rotate. The rotation of the stirring rod 403 will synchronously drive the stirring ring 404 and the turntable 405 to rotate. Since the stirring ring 404 is conical, the spray material in the box body 401 will be gathered to the middle during the rotation, breaking the centrifugal force during the stirring process, so that the spray material is stirred more evenly. At the same time, the rotation of the turntable 405 will drive the shift block 406 to shift the protrusion 409 on the outer surface of the top pipe 408, and then push the top pipe 408 to collide with the inner wall of the box body 401. In combination with the stirring of the stirring ring 404, the bubbles retained in the spray material can be pushed to the top of the box body 401, thereby ensuring the uniformity of the sprayed paint.

[0037] like Figures 2 to 4 As shown, the clearing assembly includes a filter screen plate 501 arranged in the middle of the outer surface of the box body 401, a cleaning brush 502 is arranged inside the box body 401, a push-pull rod 505 is hinged on the side of the cleaning brush 502 away from the filter screen plate 501, and one end of the push-pull rod 505 away from the cleaning brush 502 is hinged on the outer surface of the top pipe 408, and the end of the cleaning brush 502 is fixedly connected to a limiting slider 503, and the inner wall of the box body 401 is provided with a limiting slide groove 504, and the limiting slider 503 slides inside the limiting slide groove 504. A reset spring 506 is sleeved on the outer surface of the positioning rod 407, and one end of the reset spring 506 is fixedly connected to the inner wall of the box body 401, and the other end of the reset spring 506 is fixedly connected to the end of the top pipe 408;

[0038] When the top pipe 408 slides along the positioning rod 407, it will drive the cleaning brush 502 to move through the push-pull rod 505. The two ends of the cleaning brush 502 are slidably connected in the limiting slide groove 504 through the limiting slider 503, so that the cleaning brush 502 can only make a straight line movement up and down. When the cleaning brush 502 moves to the extreme position, the shift block 406 and the protrusion 409 are offset, and the return spring 506 rebounds to pull the top pipe 408 back, and then push the cleaning brush 502 to move in the opposite direction again, thereby achieving the effect of reciprocating cleaning of the filter plate 501.

[0039] like Figure 5 to Figure 6 As shown, the flip assembly includes a damping shaft 801 arranged on the outer surface of the one-way driving frame 7, the outer surface of the damping shaft 801 is fixedly sleeved with a gear ring 802, the upper surface of the machine frame 1 is fixedly connected with a frame rod 803, the inner wall of the frame rod 803 is fixedly connected with a center rod 804, the outer surface of the center rod 804 is rotatably connected with a ratchet 805, the outer surface of the center rod 804 is sleeved with a torsion spring 806, the upper part of the outer surface of the ratchet 805 is fixedly connected with a baffle 807, the frame rod 803 is arranged on the side of the one-way driving frame 7, the ratchet 805 is meshed with the gear ring 802, the end of the ratchet 805 faces downward, the torsion spring 806 is arranged on the side of the ratchet 805, and the outer surface of the baffle 807 abuts against the inner wall of the frame rod 803;

[0040] The one-way driving frame 7 can drive the positioning assembly to move upward as a whole. During the upward movement, the toothed ring 802 will engage with the ratchet 805, and then the engagement of the toothed ring 802 with the ratchet 805 during the upward movement of the positioning assembly will drive the damping shaft 801 to rotate, and then drive the positioning assembly to flip 180 degrees. After the flip is completed, the one-way driving frame 7 drives the positioning assembly to move downward as a whole. During the downward movement, it will push the ratchet 805 to rotate around the center rod 804, and the torsion spring 806 facilitates the resetting of the ratchet 805, thereby achieving the purpose of automatically flipping the clamped object and facilitating the spraying of the bottom of the object.

[0041] like Figure 5 and Figure 8 As shown, the positioning assembly includes an electric push rod 907 fixedly connected to the inside of the damping shaft 801, the driving end of the electric push rod 907 is fixedly connected to a clamping plate 901, a sleeve 902 is inserted into the side of the clamping plate 901 away from the electric push rod 907, one end of the sleeve 902 extending out of the clamping plate 901 is fixedly connected to a clamping seat 903, a clamping block 904 is hinged on the outer surface of the clamping seat 903, a round rod 905 is fixedly connected to the inner wall of the clamping plate 901, an adjusting spring 906 is sleeved on the outer surface of the round rod 905, the sleeve 902 is sleeved on the outer surface of the round rod 905, one end of the adjusting spring 906 away from the inner wall of the clamping plate 901 is fixedly connected to the end of the sleeve 902, and the side of the clamping block 904 away from the clamping seat 903 is set as an arc surface;

[0042] The electric push rod 907 pushes the clamping plate 901 to move toward the object. After the clamping block 904 abuts against the surface of the object, it will rotate around the clamping seat 903, so that the outer surface of the clamping block 904 is completely in contact with the outer surface of the object. Continuously pushing the clamping plate 901 will cause the clamping block 904 to push the sleeve 902 to move inside the clamping plate 901, and then the sleeve will slide along the round rod 905 and squeeze the adjustment spring 906. Finally, the positioning assembly will automatically adjust the extended position and length of each clamping block 904 along the outer surface of the object to clamp the object, thereby achieving the effect of clamping objects of various shapes and improving the applicability of the device.

[0043] The technical solution provided by the present invention is to adjust the spraying position by driving the pumping pipe 301 and the nozzle 6 to move in the vertical plane through the multi-directional driving frame 2. The pumping pipe 301 feeds the spraying material from the feeding pipe 302 into the box body 401, and at the same time, the motor 402 is started, and the driving end of the motor 402 rotates to drive the stirring rod 403 to rotate. The rotation of the stirring rod 403 will synchronously drive the stirring ring 404 and the turntable 405 to rotate. Since the stirring ring 404 is conical, the spraying material in the box body 401 will be moved to the middle during the rotation. The centrifugal force in the stirring process is broken, so that the spray material is stirred more evenly. At the same time, the rotating disk 405 rotates and drives the shifting block 406 to shift the convex block 409 on the outer surface of the top pipe 408, which in turn pushes the top pipe 408 to collide with the inner wall of the box body 401. The stirring of the stirring ring 404 can push the bubbles retained in the spray material to the top of the box body 401, thereby preventing the spray material sprayed from the nozzle 6 from containing bubbles, ensuring the uniformity of the sprayed paint, and achieving the purpose of improving the spray quality of the object;

[0044] In addition, when the top pipe 408 slides along the positioning rod 407, the cleaning brush 502 is driven to move through the push-pull rod 505. The two ends of the cleaning brush 502 are slidably connected in the limiting slide groove 504 through the limiting slider 503, so that the cleaning brush 502 can only make an up and down linear movement. When the cleaning brush 502 moves to the limit position, the shift block 406 and the protrusion 409 are staggered, and the return spring 506 rebounds to pull the top pipe 408 back, and then push the cleaning brush 502 to move in the opposite direction again, so as to achieve the effect of reciprocating cleaning of the filter screen plate 501, avoid the missed particulate matter in the spraying material from clogging the nozzle 6, and maintain the patency of the nozzle 6;

[0045] The object to be sprayed is placed in the middle of the machine frame 1, and the pumping pipe 301 pumps the spraying material from the feed pipe 302 into the box body 401 and then sprays it from the nozzle 6 to spray the object. After the initial spraying is completed, the electric push rod 907 is started to push the clamping plate 901 to move toward the object. After the clamping block 904 abuts against the surface of the object, it will rotate around the clamping seat 903, so that the outer surface of the clamping block 904 completely fits the outer surface of the object. Continuously pushing the clamping plate 901 will cause the clamping block 904 to push the sleeve 902 to move inside the clamping plate 901, and then the sleeve will slide along the round rod 905 and squeeze the adjustment spring 906. Finally, the positioning component will automatically adjust the extension position and length of each clamping block 904 along the outer surface of the object to clamp the object, thereby achieving the effect of clamping objects of multiple shapes and improving the applicability of the device.

[0046] After clamping is completed, the one-way driving frame 7 can drive the positioning assembly to move upward as a whole. During the upward movement, the toothed ring 802 will engage with the ratchet 805. Since a baffle 807 is provided on the upper surface of the ratchet 805, the ratchet 805 can only rotate downward around the center rod 804. Therefore, the engagement with the ratchet 805 during the upward movement of the positioning assembly will push the toothed ring 802 to drive the damping shaft 801 to rotate, thereby driving the positioning assembly to flip. Since the number of ratchet teeth 805 is half of the number of toothed rings 802, the flipping angle of the positioning assembly is one hundred and eighty degrees. After the flipping is completed, the one-way driving frame 7 drives the positioning assembly to move downward as a whole. During the downward movement, the ratchet 805 will be pushed to rotate around the center rod 804, thereby achieving the purpose of automatically flipping the clamped object, which is convenient for spraying the bottom of the object.
