[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3As shown, a plastic film label printing machine includes a structural base 1, a connecting plate 2, and a reserved groove 3. The bottom of the structural base 1 is rotatably connected to an impression wheel 5 via a bearing. A geared motor 6 is mounted on one side of the structural base 1 via a mounting bracket. A liquid storage tank 4 is fixed to the top of the structural base 1 by bolts. The connecting plate 2 is embedded inside the structural base 1. Through holes 15 are equidistantly opened inside the connecting plate 2. Diluting cotton strips 11 are embedded inside the through holes 15. A sponge pad 10 is glued to the bottom of the connecting plate 2. Reserved grooves 3 are opened inside the structural base 1 on both sides of the connecting plate 2. A rubber baffle 8 is fitted at the bottom of the reserved groove 3. A compression spring 7 is installed inside the reserved groove 3.

[0020] Among them, such as Figure 1 As shown, the output shaft of the geared motor 6 is connected to the rotating shaft of the impression wheel 5 through a connecting sleeve. The liquid storage tank 4 is provided with an injection port 12 at the top. The geared motor 6 drives the impression wheel 5 to rotate.

[0021] Among them, such as Figure 2 and Figure 3 As shown, the top of the connecting plate 2 is located inside the liquid storage tank 4, the sponge pad 10 is located on the top of the imprinting wheel 5, the bottom end of the diluting cotton strip 11 is connected to the sponge pad 10, and the dye liquid in the liquid storage tank 4 can flow into the through hole 15 and then flow into the sponge pad 10 through the diluting cotton strip 11.

[0022] Among them, such as Figure 2 As shown, a limiting plate 9 is glued to the top of the rubber baffle 8. The limiting plate 9 is located inside the reserved groove 3. The setting of the limiting plate 9 can prevent the rubber baffle 8 from falling out of the reserved groove 3.

[0023] Among them, such as Figure 1 As shown, a support plate 13 is welded to one side of the structural base 1, and a mounting block 14 is welded to one end of the support plate 13. The support plate 13 and the mounting block 14 are designed to facilitate the installation of this device on the plastic film conveying equipment by personnel using bolts.

[0024] It should be noted that this utility model is a plastic film trademark printing machine. During operation, the operator uses bolts to install the device on the plastic film conveying equipment via the mounting block 14. The device is connected to an external power source using a power cord. Dye solution is injected into the storage tank 4 through the injection port 12. The dye solution in the storage tank 4 flows into multiple through holes 15 and soaks the diluting cotton strips 11. After the diluting cotton strips 11 are soaked in the dye solution, the dye solution flows into the sponge pad 10. After the sponge pad 10 is soaked, the dye solution is applied to the outside of the printing roller 5. During the plastic film conveying process, the reduction motor 6 is turned on to drive the printing roller 5 to rotate. The printing roller 5, which has a trademark embossing on its outside, rotates to press the trademark pattern onto the plastic film, thus achieving the purpose of trademark printing. The compression spring 7 in the reserved groove 3 pushes the rubber baffle 8 down through the limiting plate 9, so that the bottom end of the rubber baffle 8 presses on the printing roller 5, which can spread the dye solution on the surface of the printing roller 5 evenly and prevent excess dye solution from leaking out.
