[0037] Embodiment one

[0038] As Figure 1 and Figure 4As shown, in this embodiment, the cleaning assembly 2 comprises: a gas gathering pipe 201 fixedly installed above the conveying belt mechanism 1, a first dust cover 202 fixedly communicated with one side of the gas gathering pipe 201, a second dust cover 203 fixedly communicated with the other side of the gas gathering pipe 201, and a cleaning roller 206 rotatably connected between the first dust cover 202 and the second dust cover 203 through a support. A first motor 207 capable of driving the cleaning roller 206 to rotate is fixedly installed on one side surface of the conveying belt mechanism 1, a fan 205 is fixedly installed at the supporting leg of the conveying belt mechanism 1, the air inlet of the fan 205 is fixedly communicated with the gas gathering pipe 201, and a sponge strip 204 is fixedly installed at the lower end of the second dust cover 203.

[0039] In this embodiment, when the substrate passes below the cleaning assembly 2, the first motor 207 operates to drive the cleaning roller 206 to rotate, so as to sweep the dust on the surface of the cleaning roller 206 into the first dust cover 202. The fan 205 operates to generate suction in the first dust cover 202 and the second dust cover 203, so as to suck out the dust. The sponge strip 204 of the second dust cover 203 wipes the substrate and adsorbs the remaining small amount of dust, so as to improve the cleaning effect, thereby avoiding the influence of the dust on the surface of the substrate on the foaming of the UV coating.

[0040] As shown in Figure 2 and Figure 3 In this embodiment, a feeding bin 304 is fixedly installed on the outer surface of the feeding pipe 303, a guide plate 305 is fixedly installed on the lower end surface of the feeding pipe 303, and a second motor 307 capable of driving the bidirectional helical blade 306 to rotate is fixedly installed on one end of the feeding pipe 303.

[0041] In specific implementation, the UV coating is poured into the feeding pipe 303 from the feeding bin 304. At this time, the two toothed baffles 5 are in the closed state. When the UV coating is higher than the bidirectional helical blade 306, the second motor 307 operates to drive the bidirectional helical blade 306 to rotate, so as to push and extrude the UV coating to the two sides, extrude the air in the UV coating, and make the air discharged from the top. At the same time, the first vibration motor 308 operates to vibrate the entire feeding pipe 303, so as to assist the air in the UV coating to be discharged, thereby uniformly dispersing the UV coating to the feeding port through the feeding assembly 3, and discharging the air bubbles in the UV coating through extrusion in the dispersion process.

[0042] As shown in Figure 3 and Figure 5As shown, in this embodiment, the defoaming component 4 includes: multiple support rings 401 symmetrically fixedly installed above the conveyor belt mechanism 1; an anilox roller 402 rotatably connected between two support rings 401; and a smoothing roller 403 rotatably connected between two other support rings 401.

A belt drive component 404 is fixedly connected to one end of the smoothing roller 403 and the anilox roller 402.

[0043] In practice, motor 405 operates, and through the transmission assembly 404, it causes the anilox roller 402 and the smoothing roller 403 to rotate simultaneously. The anilox roller 402 squeezes the substrate and UV coating to eliminate air bubbles. At the same time, vibrating motor 406 operates, causing the anilox roller 402 to vibrate, assisting the anilox roller 402 in expelling air bubbles from the UV coating and initially vibrating the UV coating to make it uniform. Then, the smoothing roller 403 rotates and presses over the surface of the UV coating to smooth the UV coating, thereby improving the air bubble elimination effect. At the same time, it also vibrates the thinner UV coating uniformly in time, improving the surface smoothness of the UV coating after curing.

[0044] Example 2

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, toothed baffles 5 are symmetrically and movably embedded on both ends of the feed tube 303. A No. 4 motor 501 is fixedly installed on both ends of the feed tube 303. A gear 502 is fixedly installed on the output end of the No. 4 motor 501. The gear 502 is meshed with the toothed baffle 5 for transmission.

[0047] In practice, motor 501 operates, driving gear 502 to rotate. Through the meshing of gear 502 with the toothed baffle 5, the toothed baffle 5 moves, exposing the feeding path below the feeding pipe 303, and the feeding path is adjusted to adapt to the feeding of substrates of different widths.
