[0040] In this embodiment, reference Figure 4 、 Figure 6 As shown, the oscillation mechanism 3 includes a rotating wheel 301, which is fixedly connected to the outer wall of the hollow shaft 201. Four cam strips 302 are fixedly connected to the outer wall of the rotating wheel 301. The four cam strips 302 are distributed in a circular array.

The outer walls of the four push rods 303 are respectively slidably connected to the top arc surfaces of the four cam strips 302. The four swing blocks 304 are fixedly connected to an oscillation rod at one end away from the four push rods 303. 305, the oscillation rod 305 is set in a U shape, and a sheath 306 is fixedly connected to the outer wall of the end of the four oscillation rods 305 away from the swing block 304. Two parallel guide pillars 307 are connected to the interior of the four swing blocks 304. The outer wall of the guide pillar 307 is slidably connected to the through hole of the swing block 304, and the top of the guide pillar 307 is fixedly connected to the bottom of the loading plate 101.

[0041] The cam bars 302 are arranged to match the positions of the four brush handles 202, ensuring that when the four sheaths 306 move to the top dead center, the four brush handles 202 just rotate to the bottom of the four sheaths 306, further ensuring that the rotation of the four brush handles 202 and the up and down swinging of the four sheaths 306 do not interfere with each other.

[0042] In this embodiment, reference Figure 4 、 Figure 7 and Figure 8 As shown, the dust calling mechanism 4 includes four dust collecting covers 401, and the four dust collecting covers 401 are respectively located at the top of the four brush handles 202. The outer walls of the two ends of the four dust collecting covers 401 are fixedly connected with pin shafts 402. The inner wall of the dust collecting cover 401 on one side close to the hollow shaft 201 is penetrated with an dust collecting hole 403. The dust collecting hole 403 passes through the inside of a pin shaft 402 close to the hollow shaft 201. The outer walls of the two pin shafts 402 are rotatably connected with a rotating seat 405, and the rotating seat 405 is fixedly connected to the inner wall of the hollow shaft 201. At the top, the ends of the four pin shafts 402 away from the hollow shaft 201 are fixedly connected to a pin disk 406. Two pins 407 are fixedly connected to the outer surface of the pin disk 406. The two pins 407 are symmetrically distributed about the center of the pin disk 406. A guide ring 408 is also included. The guide ring 408 is located on the periphery of the four dust-catching covers 401. The bottom of the guide ring 408 is provided with a plurality of arc grooves 409. The plurality of arc grooves 409 are distributed in a circumferential array. The outer wall of the pin 407 is slidably connected to the top wall of the arc groove 409.

[0043] Specifically, the hollow shaft 201 will drive the four dust collecting covers 401 during rotation, causing the four pin discs 406 to rotate synchronously, and causing the pin 407 to slide along the top wall of the arc groove 409. As the pin disc 406 rotates along the axial direction of the hollow shaft 201, it will synchronously flip back and forth along the axial direction of the pin shaft 402, further driving the dust collecting covers 401 to flip back and forth and swing, thereby expanding the dust collecting angle of the dust collecting covers 401, increasing the capture range of dust and lint, and further improving the capture effect.

[0044] In this embodiment, reference Figure 1 、 Figure 2 、 Figure 5 and Figure 8 As shown, the dust calling mechanism 4 also includes a transfer tube 404, and there are four transfer tubes 404. The four transfer tubes 404 are all fixedly connected to the outer wall of the hollow shaft 201 and are distributed in a circular array. The interior of the four transfer tubes 404 is communicated with the interior of the hollow shaft 201, and the four transfer tubes 404 are rotatably connected to the outer walls of four pin shafts 402 close to the hollow shaft 201 respectively. A sealing bushing is provided between the transfer tube 404 and the pin shaft 402. Four fixing rods 4011 are fixedly connected to the outer wall of the guide ring 408, and the top of the fixing rod 4011 is fixedly connected to the bottom of the loading plate 101. The output end of the vacuum cleaner 5 is fixedly connected to the dust suction pipe 501, and the end of the dust suction pipe 501 away from the vacuum cleaner 5 is fixedly connected to the universal connector 502, and the bottom of the universal connector 502 is rotatably connected to the top of the hollow shaft 201.

[0045] Specifically, the suction force is transmitted to the inside of the hollow shaft 201 through the dust suction tube 501 and the universal connector 502, and then to the inside of the four adapter tubes 404, and then to the inside of the four dust collecting covers 401 through the four pin shafts 402. The four dust collecting covers 401 will rotate with the four brush handles 202 to capture the dust and fluff swept down by the bristles 203 and the dust and fluff raised by the vibration of the sheath 306, so as to prevent the dust or fluff from adhering to the top of the lining cloth again.

[0046] In this embodiment, reference Figure 7 、 Figure 8 As shown, a guide block 4010 is fixedly connected to the top wall and the bottom wall of one end of the opening of the dust collecting cover 401. The two guide blocks 4010 are symmetrically arranged in an upper and lower direction, and an appropriate gap is provided between the two guide blocks 4010.

[0047] Furthermore, by setting up two guide blocks 4010, a diversion effect is played, making it easier for dust and lint to be sucked into the interior of the dust collecting cover 401, and after being sucked in, they will not escape from the interior of the dust collecting cover 401 due to the blocking effect of the two guide blocks 4010.

[0048] In this embodiment, reference Figure 1 、 Figure 2 As shown, a powder spraying device 6 is fixedly connected to the right end of the top wall of the powder dotting machine 1. The powder spraying device 6 extends into the interior of the powder dotting machine 1. A plurality of conveying rollers 7 are rotatably provided inside the powder dotting machine 1. The plurality of conveying rollers 7 are located at the bottom of the powder spraying device 6. A baffle 8 is fixedly connected to the top wall of the powder dotting machine 1. The baffle 8 is located in the middle of the powder dotting machine 1. A cloth introduction port 102 is formed through the left and right sides of the powder dotting machine 1.

[0049] Furthermore, the lining cloth is powdered by the powder spraying device 6, and the conveying roller 7 is provided to support the conveying of the lining cloth, thereby ensuring the stability of the lining cloth and limiting it to the bottom of the dust sweeping mechanism 2, the oscillating mechanism 3 and the dust calling mechanism 4, thereby ensuring the cleaning effect of the lining cloth.

[0050] In the present invention, a double-width powder coating machine is operated. When in use, the lining cloth on the external release roll is introduced into the powder coating machine 1 from a cloth introduction port 102 on the left side, passes through the bottom of the dust sweeping mechanism 2 and the oscillating mechanism 3, and then passes through the bottom of the baffle 8 to the bottom of the powder spraying device 6. Then, it is led out from a cloth introduction port 102 on the right side and fixed on the external winding roller. During this period, the lining cloth is supported by multiple conveying rollers 7 and is continuously moved to the right by the winding action of the external winding roller.

[0051] During this period, the power motor 204 and the vacuum cleaner 5 are turned on, and the output shaft of the power motor 204 drives the active bevel gear 205 to rotate, so that the passive bevel gear 206 meshing with it rotates, further driving the hollow shaft 201 to rotate, and then driving the four brush handles 202 and all the bristles 203 to rotate around the axial direction of the hollow shaft 201, cleaning the top of the lining cloth, and having a cleaning effect on the stubborn dust on the top of the lining cloth. In the process of rotation, the hollow shaft 201 will drive the rotating wheel 301 to rotate synchronously, so that the four cam bars 302 rotate around the axial direction of the hollow shaft 201, thereby pushing the four push rods 303 upwards, further driving the swing block 304. The upward movement causes the spring 308 to be compressed, so that under the continuous rotation of the rotating wheel 301, the swing block 304 is forced to slide up and down along the outer wall of the guide column 307, driving the oscillation rod 305 and the sheath 306 to swing up and down, and the sheath 306 that swings up and down is used to knock and vibrate the top of the lining cloth, so that the dust on the surface of the lining cloth is raised, and the angles and positions of the four cam strips 302 are matched with the positions of the four brush handles 202, ensuring that when the four sheaths 306 move to the top dead center, the four brush handles 202 just rotate to the bottom of the four sheaths 306, further ensuring that the rotation of the four brush handles 202 and the up and down swinging of the four sheaths 306 do not interfere with each other;

[0052] At the same time, the vacuum cleaner 5 starts to generate negative pressure suction, which is transmitted to the inside of the hollow shaft 201 through the dust suction pipe 501 and the universal connector 502, and then to the inside of the four transfer tubes 404, and then to the inside of the four dust collecting covers 401 through the four pins 402. The four dust collecting covers 401 will rotate with the four brush handles 202 to capture the dust and fluff swept by the bristles 203 and the dust and fluff raised by the sheath 306, so as to prevent the dust or fluff from adhering to the top of the lining cloth again, and the four dust collecting covers 401 will rotate around the axis of the hollow shaft 201. When rotating, the four pin discs 406 are driven to rotate synchronously, so that the pin column 407 slides along the top wall of the arc groove 409, so that in the process of the pin disc 406 rotating along the axial direction of the hollow shaft 201, it is synchronously flipped back and forth along the axial direction of the pin shaft 402, further driving the dust collecting cover 401 to flip and swing back and forth, thereby expanding the dust collecting angle of the dust collecting cover 401, increasing the dust and lint capturing range, and further improving the capturing effect. After cleaning, the lining cloth continues to move to the right under the action of the external winding roller, and is sprayed with powder dots by the powder spraying device 6.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
