[0029] The present utility model will be further described below with reference to the accompanying drawings in specific embodiments. See Figure 1 — Figure 4 :

[0030] A printing device for cotton packing film, comprising a frame group 1, a feeding roller 2 and a printing group 3 arranged in sequence on the frame group 1. The printing group 3 includes an ink cartridge slot 30 fixed inside the frame group 1 and having an upper opening, and ink is provided in the ink cartridge slot 30. A printing roller 31 is rotatably connected to the frame group 1 above the ink cartridge slot 30. The bottom of the printing roller 31 extends into the upper opening of the ink cartridge slot 30, and the bottom of the printing roller 31 is in contact with the ink. A squeegee frame 4 is slidably arranged on the frame group 1. A squeegee 40 is fixed on one side of the squeegee frame 4. When the squeegee frame 40 is driven to slide, the squeegee 40 abuts against the surface of the printing roller 31. A film pressing roller 10 is arranged on the frame group 1 and moves up and down by driving of cylinders at both ends. When the film pressing roller 10 moves downward, the bottom of the film pressing roller 10 abuts against the upper end of the printing roller 31.

[0031] During the implementation process, when the film passes between the film pressing roller 10 and the printing roller 31, the film attached to the bottom of the matte film tube 10 is pressed down by the cylinder, so that the printing roller 31 prints information on the surface of the film. The bottom of the printing roller 31 will adsorb the ink in the ink cartridge slot 30, and after the ink is printed, the surface is scraped by the squeegee 40 on one side to prevent the ink from sticking to the surface of the printing roller, so as to ensure that the subsequent surface printing can maintain a clear printing effect.

[0032] In the above structure, the squeegee frame 4 can slide to a certain extent to adjust the contact area between the squeegee and the surface of the printing roller. If too much ink adheres to the surface, the contact area between the squeegee and the surface of the printing roller 31 can be adjusted according to actual needs.

[0033] In addition, the material of the squeegee is made of silica gel, which can avoid abrasion of the information part when scraping the surface of the printing roller and ensure long-term use.

[0034] Preferably, a driven wheel 310 is fixed on the end of the printing roller 31. A servo motor 11 is arranged on the frame group 1. A driving wheel 110 is fixed on the output end of the servo motor 11. The driving wheel 11 drives the driven wheel 310 to rotate through a synchronous belt 12.

[0035] And in the above structure, a speed reducer needs to be arranged at the end of the servo motor 11 to adjust the speed when the servo motor outputs to the driving wheel 110 and ensure normal printing.

[0036] Preferably, a first film winding roller 51 and a second film winding roller 52 are arranged on the frame group 1 on both sides of the film pressing roller 10. The horizontal height of the first film winding roller 51 is less than the horizontal height of the second film winding roller 52. A third film winding roller 53 with a horizontal height lower than that of the first film winding roller 51 is arranged on one side of the feeding roller 2.

[0037] In the above structure, the upper surface of the first film winding roller 51 abuts against the bottom of the film. After passing through between the printing roller and the film pressing roller, it winds around the bottom of the second film winding roller 52, so that the film can firmly adhere to the surface of the printing roller during printing, ensuring clear printing.

[0038] Preferably, a fourth film winding roller 54 and a fifth film winding roller 55 are fixed on the frame group 1. The horizontal height of the fourth film winding roller 54 is greater than the horizontal height of the second film winding roller 52, and the horizontal height of the fifth film winding roller 55 is the same as the horizontal height of the first film winding roller 51. The fourth film winding roller 54 is located between the second film winding roller 52 and the fifth film winding roller 55.

[0039] In the above, the fourth film winding roller and the fifth film winding roller can air-dry the film after hard brushing to ensure that the ink is not easily smudged and the information is clearer.

[0040] Preferably, a film clamping mechanism 6 is arranged on the frame group 1 between the fourth film winding roller 54 and the second film winding roller 52. The film clamping mechanism 6 includes a first film clamping roller 61 fixed on the frame group 1. A second film clamping roller 62 driven by a hydraulic rod is arranged on one side of the first film clamping roller 61. When the second film clamping roller 62 is driven by the hydraulic rod, the side wall of the first film clamping roller 61 abuts against the side wall of the second film clamping roller 62. In the above structure, the film clamping mechanism 6 can fix the transported film to prevent the just-printed ink from becoming blurred due to vibration during transportation.

[0041] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
