DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0017] See Figures 1 to 4A film 101 printing device includes a frame 100, a rotatable printing roller 110 is installed on the frame 100, an ink cartridge 111 is installed below the printing roller 110, and the printing roller 110 is partially immersed in the ink cartridge 111. A pressure roller 120 is installed above the printing roller 110, and guide rollers 130 are installed on both sides of the printing roller 110. The height of the guide rollers 130 is lower than that of the pressure roller 120. The film 101 enters from one side of the frame 100, is guided by the guide rollers 130 of this layer, and is printed between the pressure roller 120 and the printing roller 110, and then leaves the frame 100 after being guided by the guide rollers 130 on the other side. The power for moving the film 101 comes from the film 101 winding device outside the frame 100.

[0018] The pressure roller 120 is installed on the first support seat 210, and the frame 100 is provided with a first guide opening 200. The first support seat 210 is placed in the first guide opening 200. A first spring 230 is provided in the first opening. The first spring 230 is located above the first support seat 210 so that it can apply a downward pressure to the first support seat 210, so that the pressure roller 120 applies pressure to the film 101, so that the film 101 is close to the printing roller 110.

[0019] To prevent the first spring 230 from deflecting during the extension and retraction process, an outwardly extending top portion is provided at the top of the first opening, a first limiting platform 221 is provided on the side of the top plate 220 facing the first support seat 210, and a second limiting platform 211 is provided on the side of the first support seat 210 extending to the outside of the frame 100 facing the top plate 220. The two ends of the first spring 230 are respectively sleeved on the first limiting platform 221 and the second limiting platform 211, thereby limiting the deflection of the first spring 230. At the same time, outwardly extending side plates 240 are provided on both sides of the first opening, and the first spring 230 is located between the two side plates 240, which can further limit the deflection of the first spring 230, thereby further preventing the first spring 230 from deflecting during the extension and retraction process.

[0020] The guide roller 130 is mounted on the second support base. The frame 100 is provided with a second guide opening, and the second support base 310 is placed in the second guide opening 300. The top of the second guide opening 300 is fixedly connected to a fixed plate 320 extending outward. The portion of the second support base 310 extending outside the frame 100 is provided with a guide rod 311. The guide rod 311 extends downward and passes through the fixed plate 320. One end of the guide rod 311 passing through the fixed plate 320 is connected to a movable plate 330, and a movable block 331 is provided in the center of the movable plate 330. At the same time, a motor 350 is provided at the bottom of the frame 100. The output shaft of the motor 350 is connected to a screw rod 340. The screw rod 340 is threadedly engaged with the movable block 331, so that the rotation of the motor 350 can drive the rotation of the screw rod 340. The rotation of the screw rod 340 can drive the movement of the movable block 331, thereby driving the movement of the movable plate 330. The movement of the movable plate 330 can drive the movement of the guide rod 311 and the second support base 310. A second spring 312 is disposed within the second guide opening 300, supporting the second support base 310. Movement of the second support base 310 changes the height of the guide roller 130, thereby varying the pressure exerted by the guide roller 130 on the film 101. Adjusting the pressure exerted by the guide roller 130 on the film 101 regulates the pressure between the film 101 and the printing roller 110. This allows for adjustments to be made to the pressure applied to the film 101 for different film types, ensuring printing quality. Guide rollers 130 are also mounted on both sides of the printing roller 110, each independently adjustable, thereby improving the precision of the pressure applied to the film 101.
