Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a coating device for forming composite sheets. Background Technology

[0002] Composite sheets refer to materials that are primarily composed of resin, with additives such as plasticizers, fillers, lubricants, and colorants as auxiliary components, and can be flowed and molded during processing. In the molding and production of composite sheets, the coating process is a crucial step. Its purpose is to uniformly cover the surface of the sheet with a specific coating material to impart special properties such as waterproofing, wear resistance, corrosion resistance, and enhanced adhesion.

[0003] Currently, existing coating equipment for composite sheet forming has certain problems in use. For example, some coating equipment has poor coating uniformity, making it difficult to ensure that the coating thickness is consistent in different positions of the composite sheet. This can lead to differences in the performance of the sheet during use, affecting product quality and service life. Moreover, coating the composite sheet requires coating both the front and back sides. However, existing coating equipment is not very efficient in coating both sides and is prone to damaging the coated surface. Therefore, there is an urgent need to design a coating equipment for composite sheet forming to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a coating apparatus for forming composite sheets, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coating apparatus for forming composite sheets includes a support platform. A first support frame is fixedly installed at the top center of the support platform, and a drying chamber is installed on the first support frame. A second support frame and a third support frame are fixedly installed on both sides of the drying chamber. A first UV lamp box and a second UV lamp box are fixedly installed on the top side of the second support frame and the top side of the third support frame, respectively. A traction mechanism is installed on one side of the second support frame and one side of the first support frame. A reverse coating mechanism and a front coating mechanism are fixedly installed at both ends of the top of the support platform, respectively.

[0007] Furthermore, multiple guide rollers are rotatably arranged on the first support frame, the second support frame, the traction mechanism, the reverse coating mechanism, the third support frame, and the front coating mechanism, and the composite sheet is wound around the guide rollers.

[0008] Furthermore, the traction mechanism includes a traction frame, and both sides of the traction frame are provided with first mounting holes. The inner wall of the first mounting hole is rotatably connected to a first mounting shaft through a bearing. A traction roller is fixedly mounted on the first mounting shaft. A motor for driving the traction roller to rotate is fixedly mounted on one side of the traction frame, and a clamping assembly is provided at the bottom of the traction frame.

[0009] Furthermore, the clamping assembly includes a first electric push rod fixedly installed at the middle of the bottom of the traction frame, and a lifting frame is fixedly installed on the piston end of the first electric push rod. A second mounting hole is opened at both ends of the lifting frame. A second mounting shaft is rotatably connected to the inner wall of the second mounting hole through a bearing, and a clamping roller is fixedly installed on the second mounting shaft. The composite sheet passes between the clamping roller and the traction roller.

[0010] Furthermore, both the first UV light box and the second UV light box include a box body, and both ends of the box body are provided with inclined guide ports. The composite sheet passes through the guide ports, and UV lamp bodies are fixedly installed at equal intervals on the top of the inner wall of both boxes.

[0011] Furthermore, the reverse coating mechanism includes a base, and a coating frame is fixedly installed on the top of the base. A coating roller is rotatably arranged on the inner wall of the coating frame near the middle, and a sprayer is fixedly installed on the side of the coating frame near the coating roller.

[0012] Furthermore, a second electric push rod is fixedly installed on the top of the inner wall of the coating frame, and a lifting frame is fixedly installed on the piston end of the second electric push rod. A smoothing roller is rotatably arranged on the inner wall of the lifting frame. The smoothing roller is located directly above the coating roller, and the composite sheet passes between the coating roller and the smoothing roller. The structure of the front coating mechanism is the same as the structure of the back coating mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, both the reverse coating mechanism and the front coating mechanism are equipped with corresponding coating components, and multiple guide rollers are used to stably guide the composite sheet, ensuring the stability of the sheet position during the coating process. At the same time, the smoothing roller in the coating mechanism can smooth the coating, effectively avoiding the problem of uneven coating thickness, ensuring the uniformity of the coating on the surface of the composite sheet, and thus improving product quality.

[0015] In this invention, the coating efficiency of the front and back sides is high and they do not interfere with each other. The front and back sides of the composite sheet can be coated sequentially. During the coating process, the sheet can move in an orderly manner through the traction of the traction mechanism and the guidance of the guide roller, which avoids mutual interference between the front and back sides during coating and damage to the coated surface, thus improving the overall coating efficiency.

[0016] In this invention, the entire device is equipped with a first UV lamp box, a second UV lamp box, and a drying oven. The coated sheet can be pre-cured in the UV lamp box and then further dried and cured in the drying oven. This ensures that the coating can be cured quickly and fully, enhances the bonding force between the coating and the sheet, improves the performance of the composite sheet, and prevents damage to the coated surface.

A second support frame 3 and a third support frame 8 are fixedly installed on both sides of the drying chamber 7, and a first UV lamp box 6 and a second UV lamp box 9 are fixedly installed on the top side of the second support frame 3 and the top side of the third support frame 8, respectively. A traction mechanism 4 is installed on one side of the second support frame 3 and one side of the first support frame 2. The traction mechanism 4 includes a traction frame 41, and a first mounting hole is provided on both sides of the traction frame 41. The inner wall of the mounting hole is rotatably connected to a first mounting shaft via bearings. A traction roller 45 is fixedly mounted on the first mounting shaft. A motor 46 for driving the traction roller 45 to rotate is fixedly mounted on one side of the traction frame 41. A clamping assembly is provided at the bottom of the traction frame 41. The clamping assembly includes a first electric push rod 42 fixedly mounted at the middle of the bottom of the traction frame 41. A lifting frame 43 is fixedly mounted on the piston end of the first electric push rod 42. Second mounting holes are provided at both ends of the lifting frame 43. A second mounting shaft is rotatably connected to the inner wall of the second mounting hole via bearings. A clamping roller 44 is fixedly mounted on the second mounting shaft. The sheet passes between the clamping roller 44 and the traction roller 45. A reverse coating mechanism 5 and a front coating mechanism 10 are fixedly installed at both ends of the top of the support platform 1, respectively. The reverse coating mechanism 5 includes a base 51, and a coating frame 52 is fixedly installed on the top of the base 51. A coating roller 53 is rotatably mounted on the inner wall of the coating frame 52 near the middle. A sprayer 56 is fixedly installed on the side of the coating frame 52 near the coating roller 53. A second electric push rod 55 is fixedly installed on the top of the inner wall of the coating frame 52, and a lifting frame is fixedly installed on the piston end of the second electric push rod 55. A smoothing roller 54 is rotatably mounted on the inner wall of the lifting frame. The flat roller 54 is positioned directly above the coating roller 53, and the composite sheet passes between the coating roller 53 and the smoothing roller 54. The structure of the front coating mechanism 10 is the same as that of the back coating mechanism 5. The front and back sides of the composite sheet can be coated sequentially through the back coating mechanism 5 and the front coating mechanism 10. The coating can be smoothed by the smoothing roller 54 in the front coating mechanism 10 and the back coating mechanism 5, which effectively avoids the problem of uneven coating thickness, ensures the uniformity of the coating on the surface of the composite sheet, and thus improves product quality. Moreover, the front and back coating is highly efficient and does not interfere with each other, which improves the overall coating efficiency.

[0025] Specifically, multiple guide rollers are rotatably arranged on the first support frame 2, the second support frame 3, the traction mechanism 4, the reverse coating mechanism 5, the third support frame 8, and the front coating mechanism 10.

[0026] Specifically, both the first UV light box 6 and the second UV light box 9 include a box body 61, and both ends of the box body 61 are provided with inclined guide ports 62. The composite sheet passes through the guide ports 62. UV lamps 63 are fixedly installed at equal intervals on the top of the inner wall of both boxes 61. The coated sheet is fully dried and cured by the cooperation of the UV light box and the drying box 7, ensuring that the coating can be cured quickly and fully, enhancing the bonding force between the coating and the sheet, improving the performance of the composite sheet, and preventing damage to the coated surface.

[0027] The working principle of this utility model is as follows: When in use, the composite sheet is wound around each guide roller and moves under the action of the traction mechanism 4. The motor 46 in the traction mechanism 4 drives the traction roller 45 to rotate, and the clamping roller 44 of the clamping assembly clamps and pulls the sheet to ensure stable movement of the sheet. Then, after the composite sheet is coated on the front side by the front coating mechanism 10, it enters the drying oven 7 for drying. Subsequently, the composite sheet enters the first UV lamp box 6 and is cured by the UV lamp body 63.

[0028] Afterwards, the composite sheet is guided into the reverse coating mechanism 5 by the traction mechanism 4 to complete the reverse coating. Then, the composite sheet continues to enter the drying oven 7 for further drying to complete the reverse drying operation. The dried sheet enters the second UV lamp box 9 for curing and is finally led out along the guide roller.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
