Description

Technical Field

[0001] The utility model relates to the technical field of resin tile processing, in particular to a resin tile curved surface roller coating device. Background Art

[0002] Resin tiles are a new type of building material. They utilize a highly weather-resistant engineering resin as their surface layer, offering excellent resistance to aging, corrosion, and weathering, maintaining their vibrant colors and stable performance over time. To facilitate assembly, resin tiles are typically not distinguished between front and back sides. During processing, resin tiles require a protective coating applied to their surface using a roller coater. Existing roller coating systems are inefficient and limited in functionality.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN204866376U applies paint to the curved resin tiles by roller coating, which does not produce spray, has a uniform coating and good thickness, and can meet the needs of mass production when combined with a drying production line.

[0004] However, the device still has some shortcomings: the device lacks the function of cleaning the surface of the resin tile. After the resin tile is formed, it needs to be placed and cooled. Only after cooling and shaping can it be roller-coated. It is easy to fall dust during the placement or transportation process. If the dust is not cleaned, it is easy to affect the quality of roller coating. Moreover, the device can only roller-coat one side of the resin tile at a time, which is inefficient.

The housing of the motor 6 is connected to the frame 1, and the output end of the motor 6 is connected to the end of one of the support shafts 2. The cleaning mechanism is connected to the frame 1 and is located near the feeding end of the frame 1. The cleaning mechanism comprises a cleaning assembly and a dust removal assembly. The cleaning assembly comprises a lower cleaning roller 7, a dust hood A8, an upper cleaning roller 9, and a dust hood B16. The lower cleaning roller 7 is rotatably connected to the frame 1 and is located between two adjacent guide rollers 3. The dust hood A8 is connected to the frame 1 and is located above the guide rollers 3, with the opening of the dust hood A8 facing downward. The upper cleaning roller 9 is located inside the dust hood A8 and is rotatably connected thereto. The dust removal assembly includes an outlet pipe 12, the output end of which is connected to the outside world. A rotating shaft 13 is provided in the outlet pipe 12 and is rotatably connected thereto. The rotating shaft 13 is coaxially connected to the impeller 15. The dust hood B16 is connected to the frame 1, and the lower cleaning roller 7 is located above the feed end opening of the dust hood B16. The output ends of the dust hood A8 and the dust hood B16 are both connected to the input end of the outlet pipe 12. The transmission mechanism includes a transmission assembly A and a transmission assembly B. The transmission assembly A includes a gear A10 and a gear B11. The transmission assembly B includes a bevel gear 14. The two gears A10 are coaxially connected to the roller shafts of the lower cleaning roller 7 and the upper cleaning roller 9, respectively, and the two gears A10 are meshed. The gear B11 is coaxially connected to one of the support shafts 2. The gear B11 is meshed with one of the gears A10, and the size of the gear B11 is larger than that of the gear A10. Two bevel gears 14 are coaxially connected to the roller shaft of the lower cleaning roller 7 and the rotating shaft 13 respectively. The two bevel gears 14 are meshed and connected to automatically clean both sides of the resin tile when the guide roller 3 is conveying the resin tile, and at the same time, dust and other impurities generated during the cleaning process are concentrated and removed. The roller coating mechanism includes a roller coating assembly and a feeding assembly. The roller coating assembly includes a coating roller A18 and a coating roller B23. The feeding assembly includes a storage box 24 and a feeding pump 25. A guide pipe A17 is provided on the frame 1. The coating roller A18 is sleeved on the guide pipe A17 and is rotatably connected thereto. The apex of the coating roller A18 is on the same plane as the apex of the guide roller 3. A bracket 19 is provided on the frame 1. The bracket 19 is connected to the slide 20. The bracket 19 is provided with a hydraulic cylinder 21 for driving the slide 20 to rise and fall. The slide 20 is connected to the guide tube B22, and the paint roller B23 is sleeved on the guide tube B22 and rotatably connected thereto. The paint roller B23 is located above the paint roller A18. The feeding assembly is connected to the bracket 19, and the feeding assembly conveys paint to the paint roller A18 and the paint roller B23 in the working state. The roller coating mechanism synchronously roller coats the upper and lower surfaces of the resin tile in the working state.

[0027] In this embodiment, the resin tile is placed on the guide roller 3, the motor 6 is started, and the motor 6 drives one of the support shafts 2 to rotate. Through the transmission of the pulley 4 and the toothed belt 5, all the support rollers 2 rotate synchronously in the same direction, and the resin tile moves toward the roller coating mechanism. When the resin tile passes through the dust removal station of the cleaning mechanism, the lower cleaning roller 7 and the upper cleaning roller 9 are linked through the gear A10, and the lower cleaning roller 7 is linked with the support shaft 2 through the gear A10 and the gear B11, so that the lower cleaning roller 7 rotates at a high speed in the opposite direction of the support shaft. The upper cleaning roller 9 rotates in the opposite direction of the lower cleaning roller 7. The lower cleaning roller 7 and the upper cleaning roller 9 rotate relative to each other and clean and remove dust from both sides of the resin tile. At the same time, due to the high-speed rotation of the lower cleaning roller 7, the rotating shaft 13 drives the impeller 15 to rotate at a high speed through the transmission of the bevel gear 14, thereby driving the air flow, thereby driving the dust to be concentrated and discharged from the outlet of the outlet pipe 12 through the air flow. The cleaned resin tile arrives at the roller coating station. At this time, the coating roller A18 and the coating roller B23 roll-coat both sides of the resin tile at the same time.

[0028] Example 2

[0029] like Figure 1 、 Figure 4 and Figure 5 As shown, the present invention proposes a device for coating curved surfaces of resin tiles with a roller. Compared to the first embodiment, this embodiment specifically discloses the structure of a feed assembly, which includes a storage box 24 and a feed pump 25. Both the storage box 24 and the feed pump 25 are connected to the bracket 19. A feed pipe is provided at the input end of the feed pump 25.

The coating rollers A18 and B23 are respectively coated on the outside of the corresponding discharge holes 171. Both the coating rollers A18 and B23 are flexible water-absorbing rollers.

[0030] In this embodiment, the paint in the storage box 24 is extracted by the feed pump 25 and injected into the guide pipe A17 and the guide pipe B22. The paint flows out through the discharge hole 171 and is absorbed by the paint roller. When the paint roller is squeezed into contact with the surface of the resin tile, the paint is rolled onto its surface.

[0031] Example 3

[0032] The present invention proposes a resin tile curved surface roller coating device. Compared with the first embodiment, the infrared transmitter and the infrared receiver are symmetrically arranged on the frame 1, and the infrared transmitter and the infrared receiver are both located on the feed side of the roller coating mechanism. The infrared transmitter and the infrared receiver are both electrically connected to the controller, and the controller is electrically connected to the feed pump 25.

[0033] In this embodiment, an infrared transmitter and an infrared receiver are used to detect whether the resin tile is in the processing position of the roller coating mechanism. If the infrared receiver interrupts the signal reception, it means that the resin tile is in the processing position. At this time, the feeding pump 25 works and adds paint to the inside of the guide pipe 17. Otherwise, the feeding pump 25 stops feeding.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
