Description

Technical Field

[0001] The invention relates to the technical field of polycarbonate sheet spraying equipment, and in particular to automatic processing equipment for polycarbonate sheet. Background Art

[0002] Polycarbonate sheets, also known as sunlight sheets, have a multi-layer hollow structure and are lightweight, light-transmitting, and heat-insulating. In the process of spraying the surface of polycarbonate sheets, the prior art usually uses a corresponding drive mechanism to drive the spray head to move, so as to achieve an automatic spraying effect on the surface of the polycarbonate sheets.

[0003] For example, the Chinese patent application number CN202210748424.0 discloses a uniform spraying device and process for polycarbonate sheets, including a lifting cylinder, a driving assembly, an adjusting assembly, a cleaning assembly, a spraying assembly, a first curing assembly, and a second curing assembly. During the spraying operation, the spray head can always be perpendicular to the spraying surface of the polycarbonate sheet, so that the spraying range and distance are consistent, thereby ensuring the uniformity of the spraying. However, for polycarbonate sheets used in special circumstances, such as protective covers and safety guardrails that require higher hardness, or building curtain walls that require stronger fire resistance and corrosion resistance, the side of the polycarbonate sheet needs to be sprayed during the spraying process, and the equipment cannot automatically spray the side of the polycarbonate sheet; if a conventional handheld spray gun is used for spraying, not only is the processing efficiency low, but it is also very easy to cause side sagging and the coating to diffuse into the hollow inner cavity of the polycarbonate sheet that does not need to be sprayed, resulting in coating differences between the side area and the middle area of ​​the entire polycarbonate sheet after spraying.

[0060] A slip ring 11, in which the slider 10 is slidably disposed, a slide rod 12 is installed at the side end of the slip ring 11, and the spraying frame 6 is installed on the slide rod 12;

[0061] A rack 13, the rack 13 is mounted on the slide bar 12;

[0062] The gear 14 is mounted on the mounting frame 5 , and the gear 14 is meshed with the rack 13 .

[0063] In this embodiment, the intermittent mechanism includes:

[0064] A driving wheel 15, which is mounted on the mounting frame 5 and is coaxially connected to the gear 14;

[0065] Rotating member 16, the rotating member 16 is mounted on the mounting frame 5, and the rotating member 16 is connected to the driving wheel 15 through a synchronous belt;

[0066] A rotating shaft 17, the rotating shaft 17 is installed on the side end of the workbench 1, and the rotating shaft 17 is connected to the rotating member 16 through a synchronous belt;

[0067] A notched rotating wheel 18, the notched rotating wheel 18 is coaxially mounted on the rotating shaft 17, and a lever 19 is mounted on the notched rotating wheel 18;

[0068] The slotted rotating wheel 20 is rotatably mounted on the side end of the workbench 1 via the second rotating shaft 21 . The second rotating shaft 21 is connected to the first rotating shaft 17 via a synchronous belt. The spraying frame 6 is mounted on the second rotating shaft 21 .

[0069] In this embodiment, the absorbent assembly comprises:

[0070] A base plate 22, the base plate 22 is installed in the middle of the rotating frame 3;

[0071] The induced draft fan 23 is installed in the base plate 22;

[0072] Shielding plates 24, there are a plurality of shielding plates 24, the plurality of shielding plates 24 are circumferentially elastically arranged on the outer edge of the base plate 22, and the middle portion of the shielding plates 24 is provided with a protruding section on the base plate 22;

[0073] The spring 25 is disposed in the base plate 22 , one end of the spring 25 abuts against the base plate 22 , and the other end of the spring 25 abuts against the back of the shielding plate 24 .

[0074] In this embodiment, if Figures 1 to 8 As shown, when in use, the drive motor 8 is started so that its output end drives the crank 9 to rotate, and the slider 10 slides back and forth in the slip ring 11 to drive the rack 13 on the slide rod 12 to slide back and forth on the mounting frame 5, and then the spraying frame 6 at the end of the slide rod 12 can slide synchronously, and the plurality of spray heads 7 on the spraying frame 6 spray the surface of the polycarbonate sheet below;

[0075] At the same time, the gear 14 meshing with the rack 13 will also drive the driving wheel 15 to rotate synchronously, and the rotation shaft 17 will rotate synchronously through the transmission of the synchronous belt and the rotating member 16. The reciprocating rotation of the rotation shaft 17 drives the lever 19 to rotate synchronously, and cooperates with the lever 19 to move the slotted rotating wheel 20 under the limit of the notched rotating wheel 18, so that the slotted rotating wheel 20 can rotate intermittently, thereby driving the rotating frame 3 and the substrate 22 thereon to rotate synchronously and intermittently, so that the shielding plate 24 on the substrate 22 can intermittently enter the hollow cavity of the polycarbonate plate to achieve positioning and temporary shielding;

[0076] At this time, the nozzles 4 arranged relatively on the rotating frames 3 on both sides can spray both sides of the middle polycarbonate sheet, while the two adjacent shielding plates 24 with the highest spraying intensity only shield one hollow cavity of the polycarbonate sheet to ensure that the layer on the side of the hollow cavity is completely covered. In this process, under the negative pressure suction of the induced draft fan 23, the excess diffused paint is absorbed through the gap between the adjacent shielding plates 24 to prevent the paint from diffusing into the hollow cavity near the spraying. Finally, with the intermittent rotation of the substrate 22, the next group of adjacent shielding plates 24 continues to spray the next unsprayed The side wall of the hollow cavity is sprayed, and under the elastic action of the spring 25 itself, the middle extending section of the shielding plate 24 extending in and out of the hollow cavity can scrape the surface coating on the side of the middle cavity after spraying, thereby avoiding the phenomenon of sagging when spraying on the side of the polycarbonate sheet, and the scraped paint will continue to be absorbed by the induced draft fan 23. In this equipment, the spraying area of ​​nozzle 1 4 overlaps with the spraying area of ​​nozzle 2 7 at both ends of the spray frame 6, avoiding color difference in the surface layer due to low paint adhesion concentration at the edge of the umbrella-shaped area of ​​spraying, thereby ensuring the consistency of appearance.

[0077] In this embodiment, if Figure 5 As shown, the slotted wheel 20 is meshed with the notched wheel 18, and the slots on the slotted wheel 20 cooperate with the lever 19. The slotted wheel 20 of the corresponding model can be replaced in time according to the spacing of different intermediate cavities in the corresponding model of the polycarbonate sheet. The number of circumferential slots thereon can be used to control the rotation frequency of the slotted wheel 20, thereby performing adaptive spraying on polycarbonate sheets of different models.

[0078] In this embodiment, if Figure 8 As shown, a top support head 26 is provided on the substrate 22, one end of the top support head 26 slides out of the outer edge of the substrate 22 and cooperates with the edge of the middle cavity of the polycarbonate sheet. A push block 27 is also provided in the substrate 22, and the push block 27 is connected to the other end of the top support head 26. The push block 27 abuts against the end of the shielding plate 24. When the substrate 22 rotates, the top support head 26 can abut against the side of the polycarbonate sheet, and the shielding plate 24 is driven by the push block 27 to move to the outside away from the side of the polycarbonate sheet to ensure that the hollow cavity of the polycarbonate sheet is temporarily shielded, and the shielding plate 24 can also be prevented from completely scraping off the spray layer attached to the side of the middle cavity, thereby ensuring the spraying effect.

[0079] In this embodiment, if Figure 7 , Figure 8 As shown, the spacing between the middle extension sections of two adjacent shielding plates 24 matches the width of the middle cavity of the polycarbonate sheet, and the width of the middle extension section of the shielding plate 24 matches the height of the middle cavity of the polycarbonate sheet. According to the size of the hollow cavity of different types of polycarbonate sheets, the corresponding shielding plates 24 are replaced in time to make the equipment more applicable.

[0080] In this embodiment, if Figure 7 As shown, there are a plurality of nozzles 4, which are arranged in pairs up and down on the inner side of the rotating frame 3. The 4 arranged in pairs up and down can cover the side ends of the polycarbonate sheet in the middle area up and down, and the spraying intensity is concentrated in the middle area of ​​the rotating frame 3, thereby improving the adhesion effect of the spraying on the side ends of the polycarbonate sheet.

[0081] In this embodiment, if Figure 4 As shown, the spray frame 6 is provided with a sleeve 28 for adjusting the spraying height of the nozzle 2 7, and a fastening bolt is set on the sleeve 28. According to the type and preparation concentration of the spray paint, the fastening bolt on the sleeve 28 is loosened or tightened to adjust the spraying height of the nozzle 2 7 accordingly to achieve the best spraying effect.
