Description

Technical Field

[0001] The utility model relates to the technical field of cigarette tipping paper printing, in particular to a printing rubber roller for cigarette tipping paper. Background Technique

[0002] Filter paper is a kind of decorative paper obtained by printing, coating and other processing methods on the original filter paper, which has the function of improving the appearance of cigarettes. The current perforated filter paper and high-permeability forming paper also have the function of reducing tar when combined. Common filter papers are orange, white, etc. The production of filter paper mainly uses coatings (color pastes) or inks for intaglio printing on the original filter paper, and the printed color is old, dull, and has a powdery texture.

[0003] For example, a printing roller for cigarette tipping paper disclosed in the utility model with the application number 202322491057.3 has a heat dissipation cylinder between the roller barrel and the roller shaft. A coolant is injected into the heat dissipation cavity of the heat dissipation cylinder through a diversion pipe. The coolant flows in from one end of the roller shaft, flows through each heat dissipation cavity in turn, and then flows out from the other end, so as to achieve the effect of dissipating heat from the roller barrel. The more the number of heat dissipation cavities, the more uniform the cooling of the roller barrel surface.

[0004] There are still deficiencies in the current situation similar to the above application:

[0005] This kind of printing roller for cigarette tipping paper has a heat dissipation effect on the inside, but the printing roller is integrally fixed. When the contact part on the outside is damaged, it cannot be replaced, and the entire printing roller for cigarette tipping paper needs to be replaced, which increases the maintenance cost and is not conducive to the production needs of enterprises.

[0006] Therefore, a printing rubber roller for cigarette tipping paper is designed to optimize the above problems. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a printing rubber roller for cigarette tipping paper to solve the related technical problems mentioned in the above background technique.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A printing rubber roller for cigarette tipping paper includes a core shaft. Installation shafts are fixed at both ends of the core shaft. A fixed tube is fixed on the outside of the core shaft. Fixed blocks are evenly arranged on the outside of the fixed tube. Limit blocks are fixed on one side of each fixed block. An outer tube is rotatably installed on the outside of the fixed blocks. Limit openings are evenly opened on the outside of the outer tube. A rubber sleeve is sleeved on the outside of the outer tube. Limit plates matching the limit openings are evenly arranged inside the rubber sleeve. Through openings are opened at the middle positions of the limit plates.

[0010] Preferably, outer rings are fixed to the outer sides of both ends of the fixed tube. Positioning openings I are evenly formed in the outer rings. Inner rings are fixed to the inner sides of both ends of the fixed tube. Positioning openings II are evenly formed in the inner rings. Bolts are installed in the positioning openings I and II in a threaded manner.

[0011] Preferably, limiting grooves are evenly formed in the outer side of the outer tube. Limiting strips are engaged in the limiting grooves, and the limiting strips are fixedly connected to the inside of the rubber sleeve.

[0012] Preferably, the limiting blocks are all made of rubber, and anti-slip particles are arranged on the outer sides of the limiting blocks.

[0013] Preferably, the limiting plates are all triangular plates and are all rubber triangular plates.

[0014] Preferably, a protective layer is arranged on the outer side of the rubber sleeve, and the protective layer is a lubricating graphite layer.

[0015] The beneficial effects of the present utility model are as follows:

[0016] A printing rubber roller for cigarette tipping paper provided by the present utility model, through the combined use of a core shaft, a mounting shaft, a fixed tube, a fixing block, a limiting block, an outer tube, a limiting opening, a rubber sleeve, a limiting plate and a through opening, can separately remove the rubber sleeve from the outer side of the fixed tube when the rubber sleeve is worn or damaged by bumping, without replacing the whole fixed tube, reducing the maintenance cost, and being simple and convenient to use, thereby improving the convenience of the printing rubber roller for cigarette tipping paper;

[0017] Through the combined use of an outer ring, a positioning opening I, an inner ring and a positioning opening II, after rotating the fixed tube to make the fixing block and the limiting block rotate simultaneously and inserting the limiting block into the through opening, bolts are respectively fixedly installed in the positioning openings I and II to fix the outer ring and the inner ring to both ends of the fixed tube and the core shaft respectively, so as to limit and fix the rotation angle of the fixed tube. It is not only convenient to install but also has high operation efficiency, thus facilitating the use of workers;

[0018] Through the combined use of a limiting groove and a limiting strip, when the rubber sleeve is fixed to the outer side of the fixed tube, the limiting strip inside the rubber sleeve is engaged and limited in the limiting groove, so that the contact area between the rubber sleeve and the fixed tube is increased, improving the adhesion of the rubber sleeve to the outer side of the fixed tube, and thus improving the firmness of the printing rubber roller for cigarette tipping paper.

[0029] When the rubber sleeve 8 is fixed to the outer side of the fixed tube 3, at the same time, the limiting bars 16 inside the rubber sleeve 8 are engaged and limited inside the limiting grooves 15, so that the contact area between the rubber sleeve 8 and the fixed tube 3 is increased, and the adhesion of the rubber sleeve 8 on the outer side of the fixed tube 3 is improved.

[0030] In this embodiment, the limiting blocks 5 are all rubber blocks, and anti-slip particles are provided on the outer sides of the limiting blocks 5.

[0031] The friction between the limiting block 5 and the through hole 10 is increased by the rubber limiting block 5 and the anti-slip particles, and the firmness of the installation is improved.

[0032] In this embodiment, the limiting plates 9 are all triangular plates, and the limiting plates 9 are all rubber triangular plates.

[0033] The rubber sleeve 8 can be more easily sleeved and fixed on the outer side of the fixed tube 3 by the rubber triangular limiting plate 9, which is convenient for installation.

[0034] In this embodiment, a protective layer is provided on the outer side of the rubber sleeve 8, and the protective layer is a lubricating graphite layer.

[0035] The protective force on the outer side of the rubber sleeve 8 is increased by the lubricating graphite layer, the friction coefficient is reduced, and the wear is reduced.
