Description

Technical Field

[0001] This utility model relates to the technical field of PVC card substrate coating equipment, specifically a surface coating equipment for the production of PVC card substrates. Background Technology

[0002] PVC card substrate surface coating involves covering the surface of a PVC card with a thin plastic film through a specific process. This film typically possesses multiple properties and functions, such as enhancing the card's surface gloss, making it appear brighter and more attractive; increasing the card's abrasion resistance, reducing scratches and wear that may occur during daily use, and extending the card's lifespan; it also provides waterproofing and moisture protection, protecting the card substrate from external environmental corrosion, while simultaneously improving the card's stain resistance and facilitating cleaning and maintenance.

[0003] According to the announcement number CN214646002U, a heat-coating mechanism for the surface of PVC film substrate is disclosed. It includes a frame, on which a film substrate feeding roll, a heat-coating feeding roll, a coating device for bonding the heat-coating film to the surface of the film substrate, and a finished film receiving roll are arranged. Between the feeding roll and the coating device, a corona roller and a dust-removing roller for removing dust from the surface of the film substrate are arranged in sequence.

[0004] This heat-coating mechanism for PVC film substrates can directly heat-melt bond the surface to be coated without special adhesives during the coating process. However, the equipment suffers from poor coating results, with defects such as bubbles and wrinkles easily appearing after coating, affecting the quality and appearance of the cards. At the same time, the existing equipment lacks a buffer mechanism during the coating process, and improper control of the coating roller pressure can easily lead to excessive force that damages the card substrate or coating material, resulting in production losses and increased costs. Therefore, the equipment needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a surface coating equipment for the production of PVC card substrates, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface coating equipment for producing PVC card substrate, comprising a base, a support mechanism fixedly connected to the top of the base, and a coating mechanism fixedly connected to the bottom interior of the support mechanism;

[0007] The coating mechanism includes a cutout platform disposed on the top of the base. Four first springs are fixedly connected to the top of the cutout platform. A horizontal bar is fixedly connected to the top of each first spring. A vertical rod is fixedly connected to the bottom of each horizontal bar. A T-shaped platform is fixedly connected to the bottom of each vertical rod. A first motor is fixedly connected to the surface of the T-shaped platform.

[0008] Preferably, a support groove is provided inside the T-shaped platform, and the surface of the coating roller is located inside the support groove, which facilitates the coating roller to perform coating within the support groove.

[0009] Preferably, sliding holes are formed inside the four ends of the vertical rod, and the surface of the vertical rod is slidably connected to the inside of the sliding holes.

[0010] Preferably, the T-shaped platform has a through hole inside, and the surface of the I-shaped rotating rod passes through the through hole inside the T-shaped platform, so as to facilitate the movement of the I-shaped rotating rod within the through hole.

[0011] Preferably, the support mechanism includes a support platform, which is fixedly connected to the top of the base. A second motor is fixedly connected to the top of the support platform, and a lead screw is fixedly connected to the bottom of the second motor. A threaded strip is threaded onto the surface of the lead screw, and the surface of the threaded strip is fixedly connected to the side of the hollow platform.

[0014] Compared with the prior art, this utility model provides a surface coating equipment for the production of PVC card substrates, which has the following beneficial effects:

[0015] 1. The surface coating equipment for producing PVC card substrates, through the coating mechanism, has a first motor driving an I-shaped rotating rod to rotate and a coating roller to rotate, allowing the coating roller to press against the workpiece surface for coating. During the coating process, the high temperature generated by the heating grid is blown by a fan to the workpiece and the coating surface, which softens the coating and makes it adhere better to the workpiece surface, thereby improving the coating quality. In addition, when the coating roller is pressed against the workpiece surface for coating, the elasticity of the first spring and the limiting action of the vertical rod can be used to buffer the workpiece surface when the coating roller is pressed against the workpiece surface, avoiding excessive force that could damage the card substrate or coating material.

[0016] 2. The surface coating equipment for producing PVC card substrates, through the set support mechanism, allows the slide plate to drive the bottom wheel to adhere to the surface of the workpiece during the movement of the workpiece, under the limiting effect of the T-shaped rod and the elastic support of the second spring. This prevents the workpiece from shifting during the coating process and ensures the smooth coating of the PVC card substrate. Attached Figure Description

[0027] Example 1

[0028] Combination Figures 2 to 5 A surface coating equipment for producing PVC card substrate includes a base 1, a support mechanism 3 fixedly connected to the top of the base 1, and a coating mechanism 2 fixedly connected to the bottom of the support mechanism 3.

[0029] The coating mechanism 2 includes a cutout platform 21, which is located on the top of the base 1. A first spring 22 is fixedly connected to each of the four ends of the top of the cutout platform 21. A horizontal bar 23 is fixedly connected to the top of the first spring 22. A vertical rod 24 is fixedly connected to the bottom of the horizontal bar 23. A T-shaped platform 25 is fixedly connected to the bottom of the vertical rod 24. A first motor 26 is fixedly connected to the surface of the T-shaped platform 25. An I-shaped rotating rod 261 is fixedly connected to the back of the first motor 26. A coating roller 27 is fixedly connected to the surface of the I-shaped rotating rod 261. Support boxes 28 are fixedly connected to both ends of the top of the T-shaped platform 25. A fan plate 281 is fixedly connected inside the support box 28. A fan 282 is fixedly connected inside the fan plate 281. An electric heating mesh 29 is fixedly connected to the bottom of the support box 28. A support groove is opened inside the T-shaped platform 25. The surface of the coating roller 27 is located inside the support groove. Sliding holes are opened inside each of the four ends of the vertical rod 24. The surface of the vertical rod 24 is slidably connected to the inside of the sliding holes.

[0030] Furthermore, a through hole is opened inside the T-shaped stage 25, and the surface of the I-shaped rotating rod 261 passes through the through hole opened inside the T-shaped stage 25. The first motor 26 drives the I-shaped rotating rod 261 to rotate and drives the coating roller 27 to rotate, so that the coating roller 27 presses on the surface of the workpiece to perform a coating operation. During the coating process, the high temperature generated by the heating grid 29 is blown by the fan 282 to the workpiece and the coating surface, which can soften the coating and make it adhere better to the surface of the workpiece, thereby improving the coating quality of the workpiece. In addition, when the coating roller 27 is pressed against the surface of the workpiece for coating, the elasticity of the first spring 22 and the limiting action of the vertical rod 24 can be used to make the coating roller 27 press on the surface of the workpiece, which plays a buffering role on the surface of the workpiece and avoids excessive force that would cause coating failure.

[0031] Example 2

[0032] See Figure 1-5 Furthermore, based on Embodiment 1, the support mechanism 3 further includes a support platform 31, which is fixedly connected to the top of the base 1. A second motor 32 is fixedly connected to the top of the support platform 31, and a lead screw 33 is fixedly connected to the bottom of the second motor 32. A threaded strip 34 is threaded onto the surface of the lead screw 33, and the surface of the threaded strip 34 is fixedly connected to the side of the hollow platform 21. Slide plates 35 are fixedly connected to both sides of the T-shaped platform 25, and a second spring 36 is fixedly connected to the bottom of the slide plate 35. A wheel frame 38 is fixedly connected to the bottom of the second spring 36, and a T-shaped rod 37 is fixedly connected to the top of the wheel frame 38. A bottom wheel 39 is provided at the bottom of the wheel frame 38.

[0033] Furthermore, a limiting groove is opened inside the lead screw 33, and the surface of the threaded bar 34 is slidably connected to the inside of the limiting groove. The bottom end of the lead screw 33 is rotatably connected to the top of the base 1. A round hole is opened inside the slide plate 35, and the surface of the T-shaped rod 37 is slidably connected to the inside of the round hole. During the movement of the workpiece, the slide plate 35, with the limiting effect of the wheel frame 38, the elastic support of the T-shaped rod 37, and the elastic support of the second spring 36, can drive the bottom wheel 39 to fit against the surface of the workpiece. This prevents the workpiece from shifting when it is being moved and coated, thus ensuring the smooth coating of the PVC card substrate.

[0034] In actual operation, when this device is used for surface coating of PVC card substrate, a conveying device is installed on the base 1 to transport the relevant product workpieces. When the workpieces are transported to the bottom of the bottom roller 39, the bottom roller 39 is used for pressing and support. Then, coating is performed. The second motor 32 drives the lead screw 33 to rotate and drives the threaded strip 34 to move downward, thereby driving the cutout table 21 and the T-shaped table 25 to move downward until the coating roller 27 is in the appropriate coating position. Then, the first motor 26 drives the I-shaped rotating rod 261 to rotate and drives the coating roller 27 to rotate. 7. Rotate and press the coating roller 27 onto the workpiece surface to perform the coating operation. During the coating process, the high temperature generated by the heating wire mesh 29 is blown by the fan 282 onto the workpiece and the coating surface, which can soften the coating and make it adhere better to the workpiece surface, thereby improving the coating quality of the workpiece. In addition, when the coating roller 27 is pressed against the workpiece surface for coating, the elasticity of the first spring 22 and the limiting action of the vertical rod 24 can be used to make the coating roller 27 press against the workpiece surface, which plays a buffering role on the workpiece surface and avoids excessive force that may cause coating failure.

[0035] Furthermore, during the lamination process, as the workpiece moves, the slide plate 35, with the wheel frame 38 under the limiting effect of the T-shaped rod 37 and the elastic support of the second spring 36, can drive the bottom wheel 39 to adhere to the workpiece surface. This prevents the workpiece from shifting during the lamination process, thus ensuring the smooth lamination of the PVC card substrate.
