[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this embodiment can be combined with each other. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 2 As shown, the present embodiment aims to provide a hot stamping film pressing device, comprising a conveyor belt 3, a fixing frame 1 mounted on one end of the conveyor belt 3, a hot stamping roller 12 mounted on the other end of the conveyor belt 3, the fixing frame 1 being in the shape of a gantry, a plurality of nozzles 2 mounted on the top and bottom of the fixing frame 1, a liquid tank being provided in the fixing frame 1, and a liquid inlet 101 being mounted on the top surface of the fixing frame 1;

[0034] The scraping mechanism further comprises: a scraping mechanism including a fixing assembly and a scraper 8, the fixing assembly including a bolt 701 and a nut 702, the scraper 8 is used to scrape moisture from the surface of the film-printed substrate, and the scraper 8 is arranged above the middle of the conveyor belt 3;

[0035] The deflation mechanism includes a heat source 1201 and an air vent 1202. The deflation mechanism is placed in the hot printing roller 12. The internal heat source 1201 of the present invention preferably adopts an electric heating tube, which is embedded in the hot printing roller.

[0036] In order to prevent the hot stamping roller 12 from rotating inconveniently, a rotating seat 10 is provided at both ends of the hot stamping roller 12. The two ends of the hot stamping roller 12 are rotatably installed in the rotating seat 10. A motor seat 5 is fixedly installed on one side of the rotating seat 10. A motor 11 is installed on the top surface of the motor seat 5. The motor 11 includes an output shaft, which is coaxially connected to the hot stamping roller 12. When the hot stamping roller 12 needs to be pressed, the motor 11 drives the hot stamping roller 12 to rotate for pressing.

[0037] The bottom of the rotating seat 10 is equipped with a hydraulic rod 9, the top of the piston rod of the hydraulic rod 9 is fixedly connected to the bottom of the rotating seat 10, and the film pressing seat 4 is fixedly installed at the bottom of the hydraulic rod 9. The bottom of the rotating seat 10 is fixedly connected to the top of the piston rod of the hydraulic rod 9. The hydraulic rod 9 can adjust the height of the rotating seat 10 through the fixed connection between the piston rod and the rotating seat 10 to accommodate film printing substrates of different heights.

[0038] In order to further facilitate the scraper 8 to normally scrape off the moisture on the surface of the film-printed substrate without affecting the subsequent film lamination, a number of ridges 301 are fixedly provided on the surface of the conveyor belt 3. The ridges 301 are used to limit the position of the film-printed substrate, and the height of the ridges 301 is less than the height of the film-printed substrate; a number of ridges 301 staggered left and right are fixedly installed on the surface of the conveyor belt 3, and the staggered ridges 301 are parallel to each other, and the height of the ridges 301 is less than the height of the film-printed substrate, which will not affect the scraping of moisture while limiting the position of the film-printed substrate, making it convenient for the scraper 8 to scrape off moisture.

[0039] It should be noted that the bottom surface of the scraper 8 is provided with a sponge strip for absorbing moisture, which can effectively absorb the moisture on the surface of the scraped film printed substrate.

[0040] In order to further adjust the scraper 8 and ensure smooth scraping of moisture, through grooves are opened on the surfaces of both ends of the scraper 8, and scraper frames 6 are installed at the bottom of both ends of the scraper 8. The top of the scraper frame 6 is fixedly connected to the bottom of the bolt 701, and the bolt 701 passes through the through groove and is threadedly installed with the nut 702. Through grooves are provided on the surfaces of both ends of the scraper 8, and a bolt 701 is fixedly installed on the top of the scraper frame 6 installed at the bottom of the scraper 8. The bolt 701 is threadedly connected to the nut 702 through the through groove. A nut 702 is also provided at the bottom of the scraper 8 on the bolt 701. The two nuts 702 cooperate with each other to adjust the height of the scraper 8. A plurality of air holes 1202 are provided on the surface of the hot printing roller 12, and the aperture of the air holes 1202 gradually increases from the inside to the outside of the hot printing roller 12, so that the hot air diffuses more evenly when it approaches the roller surface, covering more surface, improving the uniformity of the surface temperature of the hot printing roller, and avoiding fitting defects (such as bubbles and wrinkles) caused by local overheating or temperature difference; at the same time, the gradually increasing aperture reduces the gas flow rate and pressure, avoiding high-pressure hot air directly impacting the film or substrate surface. The heat source 1201 is arranged inside the hot printing roller 12, and the heat source groove is used to install the heat source 1201. The air vents 1202 provided can effectively prevent local overheating of the roller surface and reduce film pressing defects caused by uneven temperature, such as bubbles, wrinkles or incomplete fitting. The heat source 1201 directly acts on the die material (such as film) through the air vents 1202, which can soften the film material faster and make it fit more tightly. In the film pressing process, if there is air or steam between the film and the substrate, the air vents can guide the gas to be released from between the film and the substrate to avoid the formation of bubbles. The heat source 1201 is arranged inside the hot printing roller 12. Setting the heat source on the hot printing roller can ensure that the heat source directly acts on the contact surface of the film material and the target material, thereby achieving more uniform heating. This helps improve the pattern transfer quality during the thermal transfer process and reduce problems such as local overheating or uneven cooling. The heat source can better soften and adhere the film to the target surface. Especially when it is necessary to process certain special coatings or surfaces, roller surface heating can effectively help the film adhere more tightly.

[0041] During the specific use of the present invention, the scraper 8 is adjusted and fixed in height by the fixing mechanism, and then the hydraulic rod 9 is used to adjust the height of the heat printing roller 12, and the motor 11 is used to rotate the heat printing roller 12, and then the heat source 1201 is used to emit heat, and the heat is released through the air vents 1202. The film printing substrate is placed on the conveyor belt 3, and the nozzle 2 is used to clean the film printing substrate, and then the scraper 8 is used to scrape off the surface moisture through the convex strip 301, and then the heat printing roller 12 is used to transfer the pattern on the heat printing film to the target material by heating and pressurizing.
