Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a feeding adjustment mechanism for a digital label printing machine. Background Technology

[0002] Digital label printing machines, also known as self-adhesive printing machines, are equipment for printing labels and trademarks. For digital label printing machines, the feeding adjustment mechanism is also an important component. It can play a tensioning role during label feeding, improve the stability of the feeding, and avoid problems such as positional deviation during printing.

[0003] Chinese Utility Model Patent Publication No. CN220220157U discloses a multi-functional label printing machine for digital devices. The specification of this multi-functional label printing machine for digital devices describes how the machine utilizes the cooperation of various components, including a sliding plate, a fixed base, screw sleeves, a drive motor, threaded rods, movable plates, a connecting base, a driven bevel gear, a drive bevel gear, and a connecting rod. This allows the machine to easily drive two threaded rods to rotate forward, facilitating the closing of two screw sleeves. This, in turn, causes the movable plate to gradually rotate towards a vertical position, allowing the two movable plates to push the sliding plate, which in turn moves the printing roller downwards to contact the label fabric for printing. This improves the practicality of the printing machine. However, this multi-functional label printing machine for digital devices lacks a feeding adjustment structure, which can easily lead to loosening of the digital labels during feeding due to varying tension, thus affecting subsequent normal printing.

[0030] Specifically, a limiting disk 11 is provided on the outer surface of the second conveyor roller 10. At least two identical limiting disks 11 are provided. The digital label body 5 passes through the outer surface of the second conveyor roller 10 and between the two digital label bodies 5. The advantage is that, through the cooperation between the digital label body 5 and the second conveyor roller 10, when the digital label body 5 passes the outer edge of the second conveyor roller 10, it can limit the two ends of the digital label body 5, which can prevent it from easily shifting during the printing process, thus affecting normal use.

[0031] Specifically, an extension plate 7 is fixedly installed on the mounting frame 6, and a reinforcing column 8 is fixedly installed at the connection between the extension plate 7 and the mounting frame 6. The reinforcing column 8, the extension plate 7, and the mounting frame 6 together form a "triangular" structure. The advantage is that, through the design of the extension plate 7 and the reinforcing column 8, when installing, the entire mounting frame 6 can be installed on the label printing machine base 1 through the fixing holes on the extension plate 7. Subsequently, the reinforcing column 8 can enhance the deformation resistance between the mounting frame 6 and the extension plate 7, avoiding easy deformation that would affect normal use.

[0032] Specifically, the sliding seat 17 is slidably connected to the slide rail 13, and the sliding seat 17 is slidably connected to the guide rod 16. The sliding seat 17 is adapted to the lead screw 15.

[0033] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0034] Specifically, there are two identical guide rods 16 and slide rails 13. The two guide rods 16 and slide rails 13 are symmetrically distributed about the center line of the slide block 12. The advantage is that the design of the two guide rods 16 and slide rails 13 allows the slide block 17 to slide between the two guide rods 16 and slide rails 13, which can improve its stability and avoid shaking during the displacement process.

[0035] Specifically, the digital label body 5 passes through the second conveyor roller 10 and the rotating sleeve 20.

Through the design of the sliding seat 17 and the lead screw 15, when moving, the motor 14 drives the lead screw 15 to rotate, allowing the sliding seat 17 to slide above the slide rail 13. The sliding seat 17 allows for vertical movement, and the height of the components above it can be adjusted according to different situations. This allows for adjustment of the tightness of the conveyed labels, preventing them from being too loose during conveying and affecting normal printing. The design of the two guide rods 16 and the slide rail 13 allows the sliding seat 17 to slide between the two guide rods 16 and the slide rail 13, thereby improving its stability and preventing wobbling during displacement. The cooperation between the conveying roller 10 and the rotating sleeve 20 allows the conveyed labels to extend to the outer edge of the rotating sleeve 20 after passing through the conveying roller 10, improving the smoothness of conveying.
