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. The printing head 1 moves towards the direction far away from the rubber roller 2 by the decompression moment exerted on the rotating plate 8 by the decompression torsion spring 12, the printing head 1 moves towards the direction close to the rubber roller 2 by the pressurization moment exerted on the rotating plate 8 by the pressurization spring 15, and the decompression moment is larger than the pressurization moment.

The working principle of the invention is as follows:

when the housing 3 is buckled to the body 4, the poke rod 13 is extruded by the housing 3 to drive the sliding block 14 to move towards the decompression torsion spring 12, the second leg 1202 of the decompression torsion spring 12 is separated from the clamping plate 803 on the first leg 801, the decompression torsion spring 12 cannot continuously act on the rotating plate 8, and the printing head 1 mounted on the rotating plate 8 rotates clockwise in the direction shown in fig. 3 under the action of the pressurizing spring 15 and is pressed on the rubber roller 2. The pressure between the print head 1 and the rubber roller 2 is provided entirely by the pressurizing spring 15, regardless of the state of the housing 3.

When the shell 3 is opened, the poke rod 13 is separated from the shell 3, and the poke rod 13 is not limited by the shell 3. The second leg 1202 of the decompression torsion spring 12 pushes the sliding block 14 and the poke rod 13 to move outwards, the second leg 1202 of the decompression torsion spring 12 returns to the position blocked by the blocking plate 803, the rotating plate 8 rotates anticlockwise according to the direction shown in fig. 4, and the printing head 1 mounted on the rotating plate 8 is far away from the rubber roller 2 under the action of the decompression torsion spring 12.

Further, a bayonet 804 is disposed on the second leg 802, one end of the pressure spring 15 is connected to the bayonet 804, and the other end is connected to a fixed end, which may be a housing of the label printer.

Further, a heat radiation plate 11 is provided between the printhead 1 and the rotating plate 8.

Further, the pressurizing spring 15 in this embodiment is a tension spring.
