Description

Technical Field

[0001] The utility model relates to the field of cigarette equipment, and more specifically, to a lining paper printing device. Background Art

[0002] In the production process of hard-pack cigarettes, cigarettes are designed to be wrapped in liner paper and then loaded into the hard box. When taking out cigarettes, the liner paper pull tab needs to be torn off. In order to ensure the flatness and aesthetics of the liner paper packaging of cigarette packs, it is necessary to press out horizontal and vertical fine lines and unique logos on the liner paper. The printing device consists of a printing roller and a liner roller. According to the process requirements, the position of the unique logo needs to be centered left and right and flush up and down. When the position of the unique logo deviates, maintenance workers need to adjust it on the machine. The adjustment process often requires multiple attempts, and the operation is time-consuming and laborious.

[0003] In the prior art, the printing position is not adjustable. Once the end position of the integrally formed printing roller is fixed, the printing position cannot be adjusted, which cannot meet the requirements of various cigarette package specifications for special logo positions, and has an adverse effect on the quality and appearance of the cigarette package.

[0004] Long replacement cycle. Under the existing technology, a set of printing devices corresponds to a special identification position. When changing the cigarette brand or calibrating the printing position, the printing device needs to be completely dismantled and then adjusted or replaced, which takes a long time to repair and affects the machine efficiency.

[0005] Therefore, how to provide a printing device with adjustable position has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0024] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] according to Figures 1 to 3 As shown, the utility model provides a lining paper printing device, including a printing roller 4, a printing shaft 1 and two adjusting nuts 5.

[0027] The printing roller 4 is sleeved on the printing shaft 1, and the printing shaft 1 is provided with external threads 2 at both ends of the printing roller 4. Two adjusting nuts 5 are respectively connected to the printing shaft 1 through the external threads 2 to clamp the printing roller 4, and the two adjusting nuts 5 can be screwed in the same direction to adjust the specific position of the printing roller 4 on the printing shaft 1.

[0028] The utility model adopts a split-structure printing roller 4 to achieve axial adjustment between the printing roller 4 and the printing shaft 1, effectively solving the problem of special mark centering in the prior art, shortening the replacement cycle, and improving the machine operation efficiency. Furthermore, the side walls of the printing shaft 1 and the printing roller 4 that are in contact with each other are both provided with key slots 3, and the two key slots 3 are connected by a flat key. The length of the key slot 3 on the printing roller 4 is greater than the length of the flat key, so that the printing roller 4 can move axially along the flat key.

[0029] In this embodiment, a flat key slot 3 is added to the inner side of the printing roller 4, which is combined with the flat key of the printing shaft 1 to ensure that the printing sleeve can rotate with the printing shaft 1. The original printing part of the printing shaft 1 is reduced in diameter, and a flat key part is added to connect and drive with the printing sleeve; the two ends of the shaft retain the original structure, and threads are added on both sides of the original printing part, and left and right adjustment nuts 5 are provided, and the position of the printing sleeve is adjusted by rotating the adjustment nuts 5 left and right.

[0030] Furthermore, the axial movement spacing between the printing roller 4 and the printing shaft 1 is 3mm. The outer surface of the printing roller 4 has a roller pattern, and a mark is provided at the critical point of the roller pattern. The mark is used as the reference line of the roller pattern. The printing roller 4 is adjusted left and right by turning the left-hand adjusting nut 5 and the right-hand adjusting nut 5. The two ends of the thread can be adjusted by 3mm to achieve the centering of the special mark. The utility model can move the printing sleeve 3mm left and right based on the special mark, which meets the packaging requirements of cigarette packs of different specifications, reduces the difficulty of replacement and adjustment, and shortens the maintenance and replacement time.

[0031] Furthermore, the length of the embossing roller 4 is greater than the shortest distance between the two external threads 2 and less than the maximum distance between the two external threads 2. It is ensured that the adjusting nuts 5 on the two external threads 2 can firmly hold the embossing roller 4, and combined with the function of the flat key, the embossing roller 4 can rotate synchronously with the embossing shaft 1, preventing relative movement between the two, thereby causing the roller pattern on the embossing roller 4 to be misaligned.

[0032] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
