[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] According to the appendix Figure 1 - Figure 6 As shown, this utility model provides a spray painting device for advertising lightbox cloth, including a spraying machine body 1, a drying mechanism 2 on one side of the spraying machine body 1, a cleaning mechanism 4 on the other side, a high-pressure air pump 3 on the outside of the spraying machine body 1, and the spraying machine body 1 includes a side frame 11, a spraying head 12 and an advertising cloth 13.

[0034] The drying mechanism 2 includes a mounting box 21 and insert plates 26 evenly distributed at both ends of one side of the mounting box 21. Each insert plate 26 is fixedly connected to a flow guide plate 27 on one side.

[0035] The cleaning mechanism 4 includes an integrally sliding cleaning frame box 41 and a jet frame box 42. The cleaning frame box 41 is provided inside the cleaning frame box 41, and the jet frame box 42 is provided inside the air distribution pipe 45. A drive motor 43 is installed at one end of the cleaning frame box 41.

[0036] The main body 1 of the spraying machine is an advertising cloth spraying machine used in the prior art for spraying advertising light box cloth, and it has external control equipment to operate other mechanisms.

[0037] In a further embodiment, the mounting box 21 has evenly distributed slots 25 on the side near the insert plate 26, the insert plate 26 fits into the slots 25, and the curvature of the guide plate 27 gradually increases from the outside to the inside.

[0038] In this embodiment, the insert plate 26 and the diversion plate 27 are integrated and are both made of high temperature resistant material. There are four rows of insert plates 26 and diversion plates 27 at each end of the mounting box 21, which are symmetrical to each other. The curvature of the four rows of diversion plates 27 near the middle of the mounting box 21 is 60 degrees, while the curvature of the diversion plates 27 far from the middle of the mounting box 21 is 30 degrees.

[0039] In a further embodiment, a protective cover 22 is installed on the side of the mounting box 21 away from the insert plate 26, and an evenly arranged electric heating element 23 and a fan 24 are installed on the inner side of the protective cover 22.

[0040] In this embodiment, the heating element 23 generates heat after being powered on, and the fan 24 introduces external airflow, which is heated around the heating element 23 and blown onto the advertising cloth 13 for drying after spraying.

[0041] In a further embodiment, a drive shaft 402 is provided at the output end of the drive motor 43. The drive shaft 402 passes through and is fixedly connected to the wool roller 44. A toothed belt disc 48 is fixedly connected at the end of the drive shaft 402 away from the drive motor 43.

[0042] In this embodiment, the drive shaft 402 can drive the brush roller 44 to rotate and the toothed belt disc 48 to rotate. After being transmitted through the toothed belt disc 49, the air distribution pipe 45 reciprocates.

[0043] In a further embodiment, a toothed belt disc 49 is rotatably connected inside the cleaning box 41. The toothed belt disc 49 and the toothed belt disc 48 are connected by a toothed belt 401. An eccentric disc 491 is fixedly connected to one side of the toothed belt disc 49, and an eccentric shaft 492 is fixedly connected to the eccentric part of one side of the eccentric disc 491.

[0044] In this embodiment, the two ends of the air distribution pipe 45 have shafts that can be fixedly connected to the linkage block 451 and allow the air distribution pipe 45 to rotate inside the jet frame box 42.

[0045] In a further embodiment, a linkage block 451 is fixedly connected to one end of the air distribution pipe 45. The linkage block 451 has a groove for the eccentric shaft 492 to slide. An air inlet end 47 is connected to the upper part of the air distribution pipe 45, and a uniformly arranged nozzle 46 is connected to the lower part of the air distribution pipe 45.

[0046] In this embodiment, when the toothed belt disc 49 rotates, the eccentric shaft 492 drives the linkage block 451 to swing back and forth, thereby expanding the range of air jets from the nozzle 46 at the bottom of the air distribution pipe 45.

[0047] In a further embodiment, the spray head 12 is slidably connected between the two side frames 11, the advertising cloth 13 passes under the spray head 12, the advertising cloth 13 passes inside the mounting box 21 and the cleaning frame box 41, the advertising cloth 13 is attached to the brush roller 44, and the output end of the high-pressure air pump 3 is connected to the air inlet end 47 through a hose.

[0048] In this embodiment, the advertising cloth 13 has rollers at both ends, one is a release roller and the other is a take-up roller. There is a guide roller below the spray head 12, so that the advertising cloth 13 can be sprayed by the spray head 12 after passing through the guide roller.

[0049] The working principle of this utility model is as follows:

[0050] After the spray head 12 sprays the advertising cloth 13, it passes through the inside of the mounting box 21. At this time, the external control device operates the electric heating element 23 and the fan 24 to heat the airflow and dry the advertising cloth 13. The part of the hot air that cannot reach the advertising cloth 13 will be guided by multiple curved guide plates 27 inserted on the other side of the mounting box 21, so that the part of the hot airflow can preheat the part of the advertising cloth 13 that has not been sprayed by the spray head 12. In this way, the heat flow that was originally wasted can be used to preheat the unsprayed advertising cloth 13, which not only avoids waste, but also helps the adhesion of the paint when the spray head 12 sprays.

[0051] During the conveying process of the advertising cloth 13, the external control device will simultaneously operate the drive motor 43 and the high-pressure air pump 3. The operation of the high-pressure air pump 3 will cause its output end to deliver high-pressure airflow through the hose to the air inlet 47 and into the air distribution pipe 45, and then be quickly sprayed out from the nozzle 46. The operation of the drive motor 43 will cause the brush roller 44 to rotate, thereby brushing the side of the advertising cloth 13 that is being sprayed, thus cleaning the dust adsorbed on the surface of the advertising cloth 13 and sweeping the dust to the nozzle of the nozzle 46, cooperating with the nozzle. The airflow ejected from 46 removes dust, and during the rotation and cleaning process of the brush roller 44, the drive shaft 402 passing through the inside of the brush roller 44 will drive the toothed belt disc 48 to rotate, and after being driven by the toothed belt 401, the toothed belt disc 49 will rotate, which in turn causes the eccentric disc 491 and the eccentric shaft 492 to rotate together. Since the linkage block 451 fixed at one end of the air distribution pipe 45 has a groove, and the eccentric shaft 492 is located in the groove, the air distribution pipe 45 will continuously swing back and forth, thereby expanding its air jet cleaning range.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
