Description

Technical Field

[0001] This utility model relates to the field of laser transfer paper technology, specifically to a molding device for laser transfer paper. Background Technology

[0002] In existing technologies, laser films are generally made of two materials: BOPP and BOPET. BOPP can be directly embossed with laser graphics, while BOPET cannot. To emboss laser graphics on a BOPET base film, a very thin special coating must first be applied to the PET base film before embossing the laser graphics. During the coating process, it is crucial to ensure the uniformity of the coating. A search revealed a Chinese patent with authorization announcement number CN218360306U that discloses a molding device for laser transfer paper, including a fixed base and a coating roller. A first molding roller is arranged above the coating roller, and a holographic roller and a second molding roller are arranged on one side of the coating roller. A coating box is arranged below the coating roller, and a connecting plate is fixedly connected to the side of the coating box. A scraper is hinged to the upper end of the connecting plate via a hinge rod. A guide plate is hinged to the bottom of the scraper near the side of the coating box. A guide hole is provided on the side of the coating box, and one end of the guide plate is placed in the guide hole. This laser transfer paper molding equipment utilizes the contact between the scraper and the transfer paper to evenly distribute the coating on the paper, ensuring uniform coating coverage. The guide plate and guide holes allow excess coating to be reintroduced into the coating box, enabling coating recycling and preventing waste.

[0003] However, in actual use, since both the first and second molding rollers are confined inside the fixed base, the distance between the rollers remains constant, making it impossible to adjust the distance according to the thickness of the transfer paper or the coating layer, which limits the application of this solution. Utility Model Content

[0004] To address the issue that existing molding equipment lacks adjustment capabilities, this invention provides a molding device for laser transfer paper.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A molding device for laser transfer paper includes a work frame. Rollers are rotatably connected to both sides of the work frame's interior. Grooves are formed on both sides of the work frame near the rollers. Lifting assemblies are installed inside each of the two grooves. Each lifting assembly includes a vertical shaft and a lifting plate. The vertical shaft is installed at the top corner of the work frame. Through holes are formed at the corners of the lifting plates, intersecting with the vertical shafts. Vertical rods are installed on both sides of the bottom surface of the lifting plate, slidably connected to the grooves. Holes are formed on the outer walls of the vertical rods. Pressure rollers are rotatably connected between every two holes, with the two pressure rollers located directly above the two rollers. A lead screw is threaded to the center of the top surface of the lifting plate, its bottom end penetrating the lifting plate and rotatably connected to the bottom of the groove. Further, a scraper mechanism is obliquely installed on the inner side of the work frame between the two rollers. The scraper mechanism includes a plate, with fixed angle plates installed on both sides. One side of each fixed angle plate is connected to the inner wall of the work frame.

[0007] The beneficial effect of adopting the above-mentioned further solution is that excess coating on the laser transfer paper can be scraped off, making its distribution more uniform, avoiding coating accumulation that affects the molding effect, and improving the flatness and quality of the laser transfer paper surface.

[0008] Furthermore, a paint frame is installed inside the work frame. The paint frame is located at the bottom of one of the idlers. The paint frame includes a semi-column frame, and a feed port is opened at the bottom of the semi-column frame.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the design of the semi-column frame can better receive and store the paint, thereby facilitating one of the idlers to pick up the paint, and the setting of the feed inlet provides a position for the conveying mechanism to convey the paint.

[0010] Furthermore, a receiving box is installed at the bottom of the work frame, and a conveying mechanism is installed inside the receiving box. The conveying mechanism includes a pump, and the output end of the pump is connected to a pipe. The top end of the pipe is connected to the inside of the feed inlet.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the pump conveys the paint in the receiving box to the paint frame through the pipeline, realizing the automatic circulation supply of paint, and the receiving box can collect the paint scraped off from the laser transfer paper and reuse it through the conveying mechanism, avoiding paint waste and reducing production costs.

[0012] Furthermore, the receiving box includes a box body, and an inclined ramp is installed at the bottom of the inner part of the box body, with the pump located on one side of the bottom of the inclined ramp.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the inclined slope can guide the scraped paint to the location of the pump, making it easier for the pump to suck up the paint for circulation and transportation, thereby improving the paint recovery efficiency.

[0014] Furthermore, a crank handle is installed at the top of the lead screw.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the crank handle makes it easy for operators to rotate the lead screw and adjust the height of the lifting plate, the operation is simple and labor-saving, the work efficiency is improved, and the pressure adjustment is more precise.

[0016] Furthermore, the top surface of the plate is configured as a "V" shape.

[0017] The advantage of adopting the above-mentioned further solution is that the "V" shape allows excess paint to slide off to both sides, preventing paint from accumulating on the scraper.

[0018] Furthermore, the paint frame is located directly below the scraper mechanism.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the paint scraped off the laser transfer paper can fall directly into the paint box, achieving precise paint recycling and reducing paint waste and pollution to the working environment.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This laser transfer paper molding equipment, through the coordinated use of support rollers, lifting components, and pressure rollers, enables the equipment to have specific adjustment functions, thus adapting to transfer papers of different thicknesses and coating layers of different thicknesses. Specifically, by rotating the lead screw, the lifting plate can move up and down along the vertical shaft, thereby adjusting the distance between the pressure roller and the support roller, realizing flexible adjustment of the molding pressure of the laser transfer paper to adapt to laser transfer papers of different thicknesses and coating layers. Furthermore, the vertical shaft provides support and limit for the lifting plate, and the vertical rod slides in the groove, providing guidance for the lifting of the lifting plate 6002 and ensuring the stability of the pressure roller during movement.

[0032] As an embodiment of this utility model, a paint frame 500 is further installed inside the work frame 100. The paint frame 500 is located at the bottom of one of the idler rollers 200. The paint frame 500 includes a semi-column frame 5001. The bottom of the semi-column frame 5001 is provided with a feed inlet 5002. The design of the semi-column frame 5001 can better receive and store paint, thereby facilitating one of the idler rollers 200 to pick up paint.

[0035] As an embodiment of this utility model, a crank handle 6006 is further installed at the top of the lead screw 6005. The crank handle 6006 makes it convenient for the operator to rotate the lead screw 6005 and adjust the height of the lifting plate 6002. The operation is simple and labor-saving, which improves work efficiency and makes the pressure adjustment more precise.

[0036] As an embodiment of this utility model, the top surface of the plate 8001 is further configured as a "V" shape. The "V" shape allows excess paint to slide off to both sides, preventing paint from accumulating on the scraper.

[0037] As an embodiment of this utility model, the paint frame 500 is located directly below the scraper mechanism 800, which allows the paint scraped off the laser transfer paper to fall directly into the paint frame 500, thereby achieving precise paint recycling and reducing paint waste and pollution to the working environment.

[0038] Specifically, the working principle of this laser transfer paper molding equipment is as follows: When in use, the laser transfer paper is first placed on the rollers 200 on both sides of the work frame 100. The operator rotates the crank 6006 at the top of the lead screw 6005. The rotation of the lead screw 6005 drives the lifting plate 6002, which is threaded to it, to move up and down along the vertical shaft 6001. The vertical shaft 6001 provides support and limit, and the vertical rod 6003 slides and guides in the groove, thereby precisely adjusting the distance between the pressure roller 700 located directly above the idler roller 200 and the idler roller 200 to accommodate laser transfer paper of different thicknesses and coating layers, ensuring appropriate molding pressure. Before molding, the coating frame 500 located at the bottom of the idler roller 200, with its semi-column frame 5001 receiving and storing the coating, draws the coating from the receiving box 300 through the conveying mechanism 400, i.e., the pump 4001, via the pipe 4002 and delivers it to the coating frame 500 through the feed port 5002, so that the idler roller 200 dips in the coating and applies it to the laser transfer paper. Next, the scraper mechanism 800, tilted between the two rollers 200, begins operation. The two sides of the plate 8001 are connected to the inner wall of the work frame 100 via fixed angle plates 8002. Its "V"-shaped top surface scrapes away excess paint from the laser transfer paper, ensuring even paint distribution and improving the paper's surface smoothness and quality. The scraped paint, located directly below the paint frame 500, falls into the paint frame 500 for recycling. The inclined ramp 3002 within the collection box 300 guides the scraped paint to the pump 4001, achieving automatic paint recycling, avoiding waste, and reducing production costs. Finally, the pressure rollers 700, with adjusted spacing, perform a molding operation on the coated and smoothed laser transfer paper, completing the entire laser transfer paper molding process.
