Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 2-5, the self-adaptive structure of the printing head 1 of the smart label printer of the present invention includes a poke rod 13, a sliding block 14, a decompression torsion spring 12, a compression spring 15, a printing module framework back plate 7, a rotating plate 8, a rubber roller 2 and the printing head 1 installed inside the printer body 4.
The printing head 1 is arranged on a rotating plate 8, the rotating plate 8 is arranged on a back plate 7 of a framework of the printing module through a first rotating shaft 9, and a decompression torsion spring 12 is sleeved on the first rotating shaft 9. The rubber roller 2 is arranged on a back plate 7 of the framework of the printing module through a second rotating shaft 10, and the rotating plate 8 is provided with a first supporting leg 801 and a second supporting leg 802. Neither the first leg 801 nor the second leg 802 contact the sliding block 14, and the sliding block 14 does not contact the first leg 801 and the second leg 802 during movement. The first leg 801 is provided with a clamping plate 803, the first leg 1201 of the decompression torsion spring 12 abuts against the back plate 7 of the framework of the printing module, and the second leg 1202 of the decompression torsion spring 12 abuts against the clamping plate 803. The pressurizing spring 15 is connected to the second leg 802, the tap lever 13 is pressed against the housing 3 of the printer, the tap lever 13 is in contact with the slide block 14, and the slide block 14 is in contact with the extension portion 1203 of the second leg 1202 of the decompression torsion spring 12.
