Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Various embodiments of this application may exist in the form of a range. It should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a rigid limitation on the scope of this application. Therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. In addition, whenever a numerical range is indicated in this application, it means including any referenced number (fraction or integer) within the indicated range. Unless otherwise specified, all raw materials, reagents, instruments, and equipment used in this application can be purchased commercially or prepared using existing equipment.

[0025] In this application, unless otherwise stated, directional terms such as "upper" and "lower" specifically refer to the drawing directions in the accompanying drawings. Furthermore, in this application, the terms "comprising," "including," etc., mean "including but not limited to." In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this application, "and / or" describes the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of a single item or a plural item. For example, "at least one of a, b, or c", or "at least one of a, b, and c", can both mean: a, b, c, ab, i.e., a and b, ac, bc, or abc, where a, b, and c can be a single or multiple.

[0026] like Figures 1-4 As shown in the embodiment of this application, a printing unit for a dual-disc metering thermal printer is provided, comprising:

[0027] A printing plate 1, wherein a printing mechanism 2 is fixedly connected to the outer front end of the printing plate 1;

[0028] The printing mechanism 2 includes a connecting block 21. Baffles 22 are fixedly provided on both sides of the outer end of the connecting block 21 near the printing disk 1, and multiple printing strips 27 are positioned inside the baffles 22.

[0029] The front and rear ends of the printed strip 27 are symmetrically provided with a first rectangular slot 213 and a second rectangular slot 212. The first rectangular slot 213 and the second rectangular slot 212 are respectively movably inserted into the first locking rod 214 and the second locking rod 29. The other end of the second locking rod 29 is fixedly connected to the end face of the first positioning rod 28. The outer side of the first locking rod 214 is movably inserted through the middle of the second positioning rod 25, and a handle 26 is fixedly connected to the outer end face of the first locking rod 214.

[0030] A lifting fixing plate 24 is movably inserted into the upper side of the connecting block 21. The upper end of the lifting fixing plate 24 is provided with multiple printed strips 27. The lower end of the lifting fixing plate 24 is symmetrically fixedly connected with cylinders 211, which are fixedly installed inside the connecting block 21.

[0031] Specifically: The middle part of the printing disk 1 is connected to an external rotating mechanism, which can drive the printing disk 1 to rotate. As the printing disk 1 rotates continuously, the characters at the end of the printing strip 27 of the printing mechanism 2 will be printed on the surface of the displaced cable.

[0032] like Figure 3 and Figure 4 As shown: the second positioning rod 25 is fixedly connected to the front end face of the baffle 22, and the interior of the second positioning rod 25 is provided with a limiting cavity 216.

[0033] Specifically: the limiting cavity 216 limits the connection to the outer side of the first locking rod 214.

[0034] like Figure 4 As shown: The first locking rod 214 is inserted into the interior of the second positioning rod 25 and is provided with a limiting protrusion 215. Multiple compression springs 217 are provided at equal intervals between the right end of the limiting protrusion 215 and the side wall of the inner limiting cavity 216 of the second positioning rod 25.

[0035] Specifically: the compression spring 217 is in a compressed state, and the limiting protrusion 215 is used to install the compression spring 217 and limit the displacement of the first locking rod 214.

[0036] like Figure 3 As shown: The connecting block 21 has a connecting groove 210 inside, and the connecting groove 210 has a cylinder 211 and a lifting fixing plate 24 inside.

[0037] Specifically: Cylinder 211 adopts a cylinder that is already available on the market. Cylinder 211 is used to drive the lifting fixed plate 24 to move up and down.

[0038] like Figure 2 As shown: the upper end face of the printing strip 27 is higher than the upper end face of the baffle 22, and the outer end face of the printing strip 27 protrudes beyond the outer end face of the printing disk 1.

[0039] Specifically: The end of the printing strip 27 has the font for printing.

[0040] like Figure 2 As shown: A printing strip mounting cavity 23 is formed between the baffles 22.

[0041] Specifically: The printing strip 27 is installed inside the printing strip mounting cavity 23.

[0042] Operating principle: The middle part of the printing disk 1 is connected to an external rotating mechanism, which can drive the printing disk 1 to rotate. As the printing disk 1 rotates continuously, the characters at the end of the printing strip 27 of the printing mechanism 2 will be printed on the surface of the displaced cable.

[0043] Furthermore, when installing the printed strip 27, firstly, manually pull the handle 26 to move the first locking rod 214. Then, insert the printed strip 27 between the corresponding first locking rod 214 and second locking rod 29. After releasing the handle 26, under the action of the compression spring 217, the first locking rod 214 and second locking rod 29 can be inserted into the corresponding first rectangular slot 213 and second rectangular slot 212. Then, start the cylinder 211, which drives the lifting fixing plate 24 to move upward, thereby enabling each printed strip 27 to move upward and making the position of the printed strip 27 more stable.

[0044] When disassembling the printed strip 27, the cylinder 211 drives the lifting fixing plate 24 to move downward. Then, the handle 26 is pulled manually to disengage the first locking rod 214 from the first rectangular locking groove 213, thus making the disassembly of the printed strip 27 more convenient.

[0045] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
