A paper liner embossing conveyor

Abstract

This invention relates to an embossing and conveying device for inner lining paper, comprising an embossing roller, which includes an embossing roller body and a rubber ring layer fitted onto the embossing roller body. The width of the rubber ring layer matches the width of the inner lining paper. This technical solution effectively avoids leaving a dent of similar width to the inner lining paper due to friction on the surface of the embossing roller layer of the rubber layer during the inner lining paper's movement, and also avoids the rubber layer around the dent scratching the inner lining paper. This extends the service life of the rubber embossing roller. It significantly improves the service life of the device, reduces the probability of poor inner lining paper conveying due to wear during production, reduces the risk of quality defects such as poor folding of the inner lining paper, and improves production efficiency.

Description

Technical Field

[0001] This invention belongs to the field of cigarette packaging machinery technology, specifically relating to an inner lining paper embossing and conveying device. Background Technology

[0002] The FOCKE350 hard box packaging machine's inner lining paper mechanism mainly consists of four parts: an inner lining paper roll holder, an inner lining paper splicing mechanism, an inner lining paper embossing mechanism, and an inner lining paper cutting mechanism. The inner lining paper, dragged by the pressure rollers, passes through the embossing mechanism, completing the embossing process, and is then conveyed downwards to the inner lining paper cutting mechanism. Generally, the embossing rollers are made of rubber. During equipment operation, a lot of dust adheres to the inner lining paper embossing rollers, causing wear. The quality of the inner lining paper embossing is related to the wear condition of the embossing roller surface, surface cleanliness, and the pressure between the embossing rollers.

[0003] Foreign objects inside the embossing rollers, improper pressure adjustment, misalignment of the embossing rollers, and wear on the embossing rollers can all lead to abnormal embossing of the inner lining paper. This can also cause abnormal inner lining paper feeding, resulting in blockages and ultimately affecting the overall folding quality of the inner lining paper. In actual production, the embossing device needs to be cleaned, adjusted, and even replaced regularly.

[0004] Currently, the embossing roller in the inner liner mechanism of the FOCKE350 hard box packaging machine uses a steel roller against the embossing roller, and the entire roller surface is covered by a rubber layer, i.e., a rubber-coated roller. During long-term use, the inner liner paper will rub against the rubber layer surface, leaving a dent of similar width. In actual production, it has been found that after the dent appears, because the width of the inner liner paper is much smaller than the width of the rubber layer, the inner liner paper may actually cut the rubber layer during rubber layer wear, accelerating the wear of the entire embossing roller, or the rubber layer around the dent may scratch the inner liner paper, greatly shortening its service life. To avoid these situations, regular inspection and replacement are necessary. Summary of the Invention

[0005] The purpose of this invention is to provide an inner lining paper embossing conveyor to solve the problem of indentations appearing on the embossing rollers in the width range of the inner lining paper, which aggravates the wear of the entire embossing roller.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] An embossing conveying device for inner lining paper includes an embossing roller, the embossing roller including an embossing roller body, and a rubber ring layer sleeved on the embossing roller body, the width of the rubber ring layer matching the width of the inner lining paper.

[0008] Furthermore, the hardness of the rubber ring layer is not entirely the same at different points along the axial direction.

[0009] Furthermore, the hardness at both ends of the rubber ring layer is greater than the hardness of other parts.

[0010] Furthermore, two axially penetrating through holes are symmetrically arranged on the rubber ring layer with respect to the center line of the rubber ring layer. The cross-section of the through holes is a non-circular shape composed of multiple arcs.

[0011] Furthermore, protrusions are symmetrically arranged on the embossing roller body along the center line of the embossing roller, and an opening groove that mates with the protrusions is provided on the inner surface of the rubber ring layer to prevent the rubber ring layer from rotating relative to the embossing roller body.

[0012] Furthermore, an annular groove is provided on the embossing roller body, and the rubber ring layer is disposed within the annular groove; the thickness of the rubber ring layer is greater than or equal to the depth of the annular groove.

[0013] Furthermore, the width of the annular groove is the same as the width of the rubber ring layer.

[0014] Furthermore, the annular groove is inverted convex shape, and the inner diameter of the rubber ring layer matches the annular groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This technical solution effectively avoids leaving a dent of similar width on the inner liner paper due to friction on the surface of the rubber embossing roller during the inner liner paper's movement. It also prevents the rubber layer around the dent from scratching the inner liner paper. This extends the service life of the rubber embossing roller, significantly improves the overall lifespan of the device, reduces the likelihood of poor inner liner paper feeding due to wear during production, lowers the risk of quality defects such as poor inner liner paper folding, and improves production efficiency.

[0020] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.

[0021] The technical solution of this application is an improvement on the embossing roller structure of the inner liner paper mechanism of the FOCKE350 hard box packaging machine. As for whether the technical solution of this application is applicable to the embossing roller of the inner liner paper of other packaging machines, it needs to be determined according to the actual situation.

[0022] like Figure 1 As shown, this application provides an inner liner paper embossing conveying device, including an embossing roller. In the technical solution of this application, other components for realizing the embossing of the inner liner paper are also included. The structure and connection relationship of these components are all prior art, and the improvement of this technical solution does not involve the above-mentioned other components. Therefore, the applicant will not provide a detailed description here, but this does not mean that such components are not included. Moreover, this mechanism is a commonly used device in current cigarette companies, and those skilled in the art are clear about the structure of this device.

[0023] This technical solution is merely an improvement to the embossing roller, and the installation position and method of the improved embossing roller are all existing methods, which will not be described in detail here.

[0024] The embossing roller of this application includes an embossing roller body 1, on which a rubber ring layer 2 is fitted. The width of the rubber ring layer in this application matches the width of the inner lining paper. The width of the inner lining paper here is the width of the inner lining paper that matches the cigarette box of currently sold cigarettes. And as needed, such as when the model changes, it is only necessary to fit the rubber ring layer of the corresponding width onto the embossing roller body.

[0025] In this embodiment, the hardness of the rubber ring layer is not entirely the same at different points along the axial direction. Here, it refers to the length direction of the rubber ring layer. The hardness of the two end areas is greater than that of the middle part. The reason for adopting this technical solution is that, through force testing, when the embossing roller is performing embossing operations, the force on its two sides and the middle part is actually greater than the force on other parts. However, the support of the middle part is greater than that at both ends because the two ends of the rubber ring layer will extend outward to a certain extent when subjected to force. Therefore, in order to overcome the extension of the two ends of the rubber ring layer, the hardness of the two ends is greater than that of the middle part. At the same time, it can also effectively overcome the damage such as cutting of the rubber ring layer by the inner lining paper.

[0026] The embossing roller body has protrusions symmetrically arranged along its centerline. An opening groove, matching the protrusions, is provided on the inner surface of the rubber ring layer to prevent relative rotation between the rubber ring layer and the embossing roller body. Installation or removal of the rubber ring layer can be achieved by pulling outwards or pushing inwards along the axial direction of the embossing roller body. The most important function of the protrusions is to prevent rotation, and when there are four protrusions (two pairs), the supporting force on the rubber ring layer is also increased.

[0027] In other embodiments of this application, to reduce wear between the inner liner paper and the embossing roller, the structure of the rubber ring layer can be improved. Specifically, the rubber ring layer can be designed with two axially penetrating through holes symmetrically arranged around its centerline. The cross-section of these through holes is non-circular, composed of multiple arc shapes. This structure allows the rubber ring layer to absorb excessive pressure through the deformation of the through holes, thereby reducing wear between the inner liner paper and the rubber ring layer.

[0028] In other embodiments of this application, an annular groove is provided on the embossing roller body, and the rubber ring layer is disposed within the annular groove; the thickness of the rubber ring layer is greater than or equal to the depth of the annular groove. This application can also be produced by vulcanizing the rubber ring layer onto the embossing roller body. The annular groove structure reduces axial deformation of the rubber ring layer under pressure, and the annular groove is inverted U-shape. The inner diameter of the rubber ring layer matches the annular groove, thereby increasing the support force on both ends of the rubber ring layer through the embossing roller body.

[0029] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that the technical solutions of this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the technical solutions of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the specification should be construed as limiting the scope of the claims.
