Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat transfer film production technology, specifically to a heat transfer film coating mechanism. Background Technology
[0002] Heat transfer film is a functional material used for surface decoration. It consists of a multi-layered structure and is primarily used to transfer patterns onto various substrates. Its core principle is to achieve transfer through heat and pressure, ensuring the pattern is durable and aesthetically pleasing. Applying adhesive is the core step in the heat transfer process, ensuring the adhesive layer is effectively transferred to the substrate. The process is divided into two stages: adhesive layer preparation and heat-pressing transfer.
[0003] For example, a heat transfer film coating mechanism, as described in application number CN202420822628.9 and authorized announcement date 20241213, includes a processing table. An unwinding roller is movably connected to the upper left side of the processing table, and a take-up roller is movably connected to the upper right side of the processing table. A heat transfer film is movably connected to the outer surfaces of the unwinding and take-up rollers. A coating tank is fixedly inserted into the lower end of an adjusting component, and a coating tube is fixedly installed at the lower end of the coating tank. A driving component is provided at the upper end of the adjusting component, and a rod is fixedly installed at the lower end of the driving component. This mechanism aims to solve the problem of glue clogging affecting production. The key technical point is: a heat transfer film coating mechanism. This invention physically stirs the glue inside the coating tube during the insertion and rotation of the rod. This stirring action helps break up any clumps or impurities in the glue, making it more uniform, thereby reducing clogging and ensuring the production of the heat transfer film.
[0004] Traditional heat transfer film coating devices lack effective dust removal and cleaning functions, making it impossible to remove dust from the heat transfer film substrate. Dust on the substrate will affect the bonding quality between the adhesive layer and the substrate. Furthermore, the pressure control of the adhesive supply system is not precise, which can easily cause fluctuations in the amount of adhesive and affect the coating effect. Therefore, it is urgent to design a heat transfer film coating mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a heat transfer film coating mechanism to overcome the above-mentioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A heat transfer film coating mechanism includes a frame, a processing area on one outer wall of the frame, and an installation area on one outer wall of the top of the frame. The installation area houses a coating assembly, which includes four lifting cylinders, a sliding frame, a dust collection box, and a coating storage box. Each of the four lifting cylinders is bolted to one of the four corners of the bottom of the installation area's inner wall. The sliding frame is slidably connected inside the processing area and is bolted to the output ends of the four lifting cylinders. A dust collection hood is bolted to one outer wall of the bottom of the sliding frame. A dust collection pump is located on one outer wall of the top of the dust collection box. A door is installed on one side of the outer wall via a hinge. The dust collection box is connected to the dust collection hood via a telescopic pipe. A glue spraying base is installed on one side of the bottom outer wall of the sliding frame via bolts. Multiple glue outlet holes are opened on one side of the bottom outer wall of the glue spraying base. A rubber plug is threaded onto one side of the top outer wall of the glue storage box. Push cylinders are installed on both sides of the top outer wall of the glue storage box via bolts. A push slide plate is slidably inserted inside the glue storage box. The top of the push slide plate slides through the glue storage box. The output ends of the two push cylinders are installed together with the push slide plate via bolts. The glue storage box is interconnected with the glue spraying base via a telescopic pipe.
[0008] Furthermore, four scraper assemblies are bolted to the outer wall of one side of the bottom of the sliding frame. Each scraper assembly includes a hinge seat and a mounting seat. A scraper plate is mounted on the bottom end of the hinge seat via a hinge. A hinge frame is welded to the outer wall of one side of the scraper plate.
[0009] Furthermore, an adjusting cylinder is installed inside the mounting base via a hinge, and the output end of the adjusting cylinder is rotatably connected to the hinge frame via the hinge.
[0010] Furthermore, limit components are installed on both sides of the bottom outer wall of the sliding frame by bolts, and three air jet boxes are installed on one side of the bottom outer wall of the sliding frame by bolts, with multiple through holes at the bottom of the air jet boxes.
[0011] Furthermore, the gluing assembly also includes a blower and three heating boxes. The blower is bolted to one side of the bottom wall of the installation area, and the bottom ends of the three heating boxes are bolted to the other side of the bottom wall of the installation area. Two air supply pipes are provided between the three heating boxes, and the output end of the blower is connected to one of the heating boxes through a pipe.
[0012] Furthermore, multiple heating rods are bolted to the top of the inner wall of the heating box, and each of the three heating boxes has a telescopic tube bolted to its bottom, with the bottom of each of the three telescopic tubes being installed together with the three air jet boxes.
[0013] Furthermore, the limiting component includes a mounting shell, the top of which is bolted to one side of the bottom of the sliding frame, a mounting bracket is slidably inserted into the bottom of the mounting shell, and an anti-stick pressure roller is mounted inside the mounting bracket via a bearing. Multiple connecting springs are bolted to the outer wall of one side of the top of the mounting bracket, and the tops of the multiple connecting springs are bolted to the top of the inner wall of the mounting shell.
[0014] In the above technical solution, the heat transfer film coating mechanism provided by this utility model has the following advantages:
[0015] (1) This utility model can effectively remove dust and impurities from the surface of the heat transfer film substrate by setting up a dust collection box, dust collection hood and dust collection pump integrated into the glue application component. In this process, the dust collection hood is connected to the dust collection box through a telescopic pipe and adsorbs dust in real time during the lifting and lowering of the sliding frame, avoiding the problem of poor bonding between the glue layer and the substrate caused by dust pollution in traditional devices, significantly improving the adhesion of the adhesive layer and the product quality. At the same time, when applying glue, the cooperation between the glue storage box, the sliding plate and the cylinder ensures that the glue is continuously and stably supplied to the glue spraying station, and the multiple glue outlet holes at the bottom of the glue spraying station achieve uniform glue application, solving the risk of glue blockage and improving production efficiency.
[0016] (2) The design of the scraper assembly of this utility model can precisely adjust the angle and pressure of the scraper. This process is achieved by adjusting the rotation connection between the output end of the cylinder and the hinge frame, which can dynamically control the scraping force, ensuring that the glue is evenly distributed on the surface of the heat transfer film, avoiding uneven glue layer thickness or glue overflow. This structure significantly improves the glue application accuracy and reduces material waste during glue application. It is especially suitable for high-precision pattern transfer, enhancing the overall aesthetics and durability of the heat transfer film.
[0017] (3) The coordinated operation of the jet box and heating components of this utility model can provide uniform hot air drying immediately after the glue is applied. In this process, the blower delivers the airflow to the heating box. After being heated by the heating rod, the airflow is guided through the air supply pipe and telescopic pipe to the through hole of the jet box to quickly cure the glue layer, which greatly shortens the drying time and prevents the glue from flowing or deforming. At the same time, the distribution position of the jet box optimizes the hot air flow field, ensuring that the glue layer is quickly set, improving production continuity and energy saving.
[0018] (4) The limiting component of this utility model adopts an adaptive structure of connecting spring and anti-sticking pressure roller. The mounting shell supports the mounting frame through the connecting spring, so that the anti-sticking pressure roller can automatically adjust the pressure according to the thickness of the heat transfer film substrate, avoiding the offset or wrinkles in the substrate transmission process, ensuring accurate glue application position, and the anti-sticking pressure roller reduces glue adhesion, ensuring the stability and continuity of the glue application process, and reducing equipment failure rate.

[0038] This embodiment further defines the features of Embodiment 1. Four scraper assemblies 10 are bolted to one side of the bottom outer wall of the sliding frame 6. Each scraper assembly 10 includes a hinge seat 25 and a mounting base 27. A scraper blade 26 is hinged to the bottom of the hinge seat 25. Driven by an adjusting cylinder 28, the scraper blades 26 of the four scraper assemblies 10 have their angle and pressure adjusted via a hinge frame 29 to scrape off excess adhesive, ensuring a uniform adhesive layer thickness and preventing overflow or localized accumulation. A hinge frame 29 is welded to one side of the outer wall of the scraper blade 26. An adjusting cylinder 28 is hinged inside the mounting base 27. The preferred model of the adjusting cylinder 28 is Fess. The oDSNU-16-50-P is used, and the output end of the regulating cylinder 28 is rotatably connected to the hinge frame 29 via a hinge. Limiting components 7 are bolted to the outer walls of both sides of the bottom of the sliding frame 6. Three air jet boxes 11 are bolted to one side of the bottom of the sliding frame 6, and multiple through holes are opened at the bottom of the air jet boxes 11. The gluing assembly 4 also includes a blower 16 and three heating boxes 17. The blower 16 is preferably a Senz GM5.5. The blower 16 is bolted to one side of the bottom of the inner wall of the installation area 3. The bottom of the three heating boxes 17 is bolted to the other side of the bottom of the inner wall of the installation area 3. Two air supply points are provided between the three heating boxes 17. Pipe 19 and the output end of blower 16 are connected to one of the heating boxes 17 via a pipe. Multiple heating rods 20 are bolted to the top of the inner wall of heating box 17. The preferred model of heating rod 20 is Aode Machinery SRY6-380V / 3KW. Each of the three heating boxes 17 has a telescopic fitting 18 bolted to its bottom. Blower 16 delivers airflow into heating box 17, which, after being heated by the heating rods 20, is distributed to the three heating boxes 17 via air supply pipe 19. The hot air is guided through the telescopic fittings 18 into the air jet box 11 and sprayed out from its bottom through-hole to quickly cure the adhesive layer, preventing dripping or deformation. The bottom ends of the three telescopic fittings 18 are respectively connected to… Three jet boxes 11 are installed together; the limiting assembly 7 includes a mounting shell 30, the top of which is bolted to one side of the bottom of the sliding frame 6, and a mounting bracket 32 is slidably inserted into the bottom of the mounting shell 30. An anti-stick pressure roller 33 is installed inside the mounting bracket 32 through a bearing. The anti-stick pressure roller 33 rotates itself to reduce adhesion; multiple connecting springs 31 are bolted to the outer wall of the top side of the mounting bracket 32. The anti-stick pressure roller 33 of the limiting assembly 7 adaptively adjusts the pressure under the elastic support of the connecting springs 31 to ensure that the substrate is flat and adhered, and to prevent displacement or wrinkles; and the tops of the multiple connecting springs 31 are bolted to the top of the inner wall of the mounting shell 30.
[0039] Working Principle: The heat transfer film substrate enters the processing area 2 of the frame 1, ready for adhesive application. Four lifting cylinders 5 are then activated, their output ends extending downwards simultaneously. The output ends of the lifting cylinders 5 drive the sliding frame 6 to slide downwards along the inner wall of the processing area 2, causing the sliding frame 6 to descend closer to the substrate. As the sliding frame 6 descends, the limiting components 7 installed on both sides of its bottom first contact the substrate. The mounting shell 30 descends with the sliding frame 6, and the anti-stick roller 33 at the bottom of the mounting frame 32 presses against the substrate surface. If the substrate thickness changes or rises due to tension fluctuations, the mounting frame 32 will slide upwards within the mounting shell 30, compressing the connecting spring 31. The spring provides adaptive pressure, ensuring that the anti-stick roller 33 always effectively presses against the edge of the substrate, preventing it from shifting or wrinkling. Simultaneously, the anti-stick roller 33 rotates to reduce adhesion. After the sliding frame 6 descends to its final position, the dust collection cover 8 fixed to the bottom of the sliding frame 6... Approaching the substrate surface, the vacuum pump 13 starts, generating negative pressure airflow below the vacuum hood 8. Dust and impurities on the substrate surface are sucked into the vacuum hood 8 and transported to the vacuum box 12 for storage through the telescopic pipe. Accumulated dust can be cleaned by opening the box door 14. As the external winding equipment rewinds, the clean substrate moves to below the glue spraying station 9 at the bottom of the sliding frame 6. Two downward-pushing cylinders 23 start, their output ends pushing the downward-pushing slide plate 24 downwards. The downward-pushing slide plate 24 moves downwards, applying constant pressure to the glue in the glue storage tank 15. The pressurized glue is transported from the glue storage tank 15 to the glue spraying station 9 through the telescopic pipe. The glue is evenly extruded from multiple glue outlets 21 at the bottom of the glue spraying station 9, coating the substrate surface passing below. After the glue is extruded, the substrate immediately moves to below the scraper assembly 10, where the scraper blade 26... The blade is connected to the bottom of the hinge seat 25 via a hinge, and its blade contacts the surface of the substrate after adhesive application. During this process, the output end of the adjusting cylinder 28 pushes or pulls the hinge frame 29 welded to the scraper plate 26 via the hinge, thereby dynamically adjusting the angle and pressure of the scraper plate 26 relative to the substrate. As the substrate moves, the scraper plate 26 precisely scrapes the adhesive layer on the surface of the substrate, removing excess adhesive and ensuring that the adhesive layer thickness is uniform and consistent without overflow. After the substrate is scraped and leveled, it moves to the bottom of the sliding frame 6 under the three air jet boxes 11. The blower 16 is started to generate airflow. The airflow enters one of the heating boxes 17 through a pipe. At the same time, the airflow flows between the three heating boxes 17 through the air supply pipe 19. Multiple heating rods 20 installed at the top of each heating box 17 heat the flowing airflow. The heated airflow passes through the telescopic pipe 18 at the bottom of each heating box 17. The hot air is delivered to the corresponding jet box 11. The hot air is blown evenly from multiple through holes at the bottom of the jet box 11 onto the substrate surface coated with adhesive. The hot air promotes the rapid curing of the adhesive, prevents it from flowing and deforming, and shortens the drying time.
