[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0036] For technologies, methods, and devices known to those of ordinary skill in the relevant fields, they may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0037] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0038] In the description of the present application, it should be understood that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meaning, and therefore cannot be understood as a limitation on the scope of protection of the present application.

[0039] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0040] Rollers, such as traction rollers or guide rollers, are important components of mechanical equipment such as gravure printing machines.

[0041] During installation, the rollers are usually connected to support members such as the frame through both ends to achieve installation on the mechanical equipment.

[0042] For different mechanical equipment, such as different types of mechanical equipment, and the same type but different models of mechanical equipment, the size of the installation space for installing the rollers (i.e., the distance between two points on the support member for connecting with the rollers) is usually not the same. For example, for different models of gravure printing machines, the size of the installation space for installing the rollers is different.

[0043] In the related art, the length of the roller is fixed, and the same roller cannot be installed in different installation spaces. For different installation spaces, usually only rollers of different specifications can be replaced, which means that the roller cannot adapt to different mechanical equipment and has poor flexibility in use.

[0044] In view of the above situation, the present application provides a roller.

[0045] Figures 1-3 Exemplarily shows the structure of the roller of the present application.

[0046] See Figures 1-3 , in the present application, the roller 10 includes a roller body 1. The roller body 1 includes a first section 11 and a second section 12. The first section 11 is sleeved outside the second section 12 and is used to contact the material. The second section 12 is used to connect with a support member (not shown) and is movable relative to the first section 11 so that the length of the roller body 1 is adjustable.

[0047] Based on the above settings, the roller 10 is no longer of a fixed length but becomes length-adjustable. In this way, the same roller 10 can adapt to different-sized installation spaces and be applied to different mechanical equipment. Therefore, the flexibility in use is higher.

[0048] It can be seen that by setting the movable second section 12 in the first section 11 to achieve the adjustable length of the roller 10, the flexibility in use of the roller 10 can be effectively improved, the applicable range of the roller 10 can be expanded, and the roller 10 can adapt to different mechanical equipment.

[0049] See Figures 1-3 , in some embodiments, a locking mechanism 2 is provided on the second section 12. The locking mechanism 2 locks the second section 12 during the movement of the second section 12 relative to the first section 11. In this way, when the second section 12 moves to a certain target position, the locking mechanism 2 can be used to lock the second section 12 so that the second section 12 can be stably maintained at the corresponding target position. In this way, the roller 10 can be stably maintained at the required length and is more convenient to be installed in different-sized installation spaces.

[0050] As an example of the locking mechanism 2, refer to Figure 2 and Figure 3 , in some embodiments, the locking mechanism 2 includes a locking unit 21, and the locking unit 21 includes a locking member 22. The locking member 22 is movably arranged on the second section 12 to move between a first position and a second position. When in the first position, the locking member 22 locks the second section 12 to the first section 11, and when in the second position, the locking member 22 releases the locking of the second section 12. In this way, when the length of the roller 10 does not need to be adjusted, such as after the adjustment is completed, the locking function can be realized by moving the locking member 22 to the first position, so that the roller 10 is stably maintained at the required length. Also, when the length of the roller 10 needs to be adjusted, the locking can be released by moving the locking member 22 to the second position, which facilitates the movement of the second section 12 in the first section 11, changes the length of the roller 10, and realizes the adjustment of the length of the roller 10.

[0051] Wherein, the movement of the locking member 22 between the first position and the second position can be translation and / or rotation, that is to say, the locking member 22 can be rotatably and / or movably arranged on the second section 12 to lock or unlock by rotating or translating between the first position and the second position.

[0052] In addition, the locking member 22 can realize the locking function by connecting with the side surface and / or end surface of the first section 11. Among them, as an example of the locking member 22 connecting with the side surface of the first section 11 to realize the locking function, a clamping groove is provided on the side surface of the first section 11, and the locking member 22 in the first position is clamped into the clamping groove. In this way, the locking member 22 fixes the second section 12 to the first section 11 by clamping on the side surface of the first section 11, and realizes the locking of the second section 12 on the first section 11. And as an example of the locking member 22 connecting with the end surface of the first section 11 to realize the locking function, refer to Figure 1 and Figure 2 , the locking member 22 and the end surface of the first section 11 are connected by a connecting member 24 such as a bolt. In this way, the locking member 22 fixes the second section 12 to the first section 11 by being connected to the end surface of the first section 11 by the connecting member 24, and realizes the locking of the second section 12 on the first section 11.

[0053] Refer to Figure 2 , in some embodiments, a groove 15 is provided on the second section 12. When in the second position, the locking member 22 is received in the groove 15. In this way, when in the second position, the locking member 22 does not protrude from the second section 12, and it is less likely to hinder the movement of the second section 12. Therefore, it is beneficial to improve the movement smoothness of the second section 12 and realize a more efficient and labor-saving length adjustment process.

[0054] In the foregoing embodiments, the number of the locking members 22 in the locking unit 21 is not limited and may be one, two or more (i.e., at least three). Among them, when the locking unit 21 includes at least two locking members 22, the at least two locking members 22 are arranged at intervals along the circumferential direction of the first section 11. In this way, the locking unit 21 can lock the second section 12 to the moved position more stably and firmly, achieving a more stable locking effect.

[0055] In addition, referring to Figure 2 , in some embodiments, the locking mechanism 2 includes at least two locking units 21, and the at least two locking units 21 are arranged at intervals along the moving direction of the second section 12. In this way, the locking mechanism 2 can lock the second section 12 at different positions through different locking units 21, so that the second section 12 is more stably held at different positions, and further the roller 10 is more stably held at different lengths, and more flexibly adapts to different sizes of installation spaces.

[0056] As a further improvement to the foregoing embodiments, referring to Figure 2 and Figure 3 , in some embodiments, an anti - detachment member 3 is provided at one end of the second section 12 located in the first section 11. The anti - detachment member 3 contacts the end face of the first section 11 to prevent the second section 12 from detaching from the first section 11. In this way, the anti - detachment member 3 can limit the maximum moving displacement of the second section 12 relative to the first section 11, preventing the second section 12 from accidentally slipping during the moving process, which is beneficial to further facilitate the adjustment of the length of the roller 10 and improve the efficiency of the roller length adjustment.

[0057] In the foregoing embodiments, the roller body 1 may only include one movably arranged second section 12. In this case, only one end of the roller body 1 has an adjustable length, and the other end has a non - adjustable length; or, referring to Figure 1 and Figure 2 , the roller body 1 may also include two movably arranged second sections 12, and the two second sections 12 are arranged at opposite ends of the first section 11. In this case, both ends of the roller body 1 have adjustable lengths, which is beneficial to expanding the length adjustment range of the roller 10, enabling the roller 10 to adjust its length within a larger range and adapt to more different sizes of installation spaces.

[0058] As an example of the first section 11 in the foregoing embodiments, referring to Figures 1-3 , the first section 11 includes a body 13 and a roller sleeve 14, and the roller sleeve 14 is arranged on the outer surface of the body 13. In this way, not only can the body 13 be protected through the roller sleeve 14 to reduce the wear of the body 13, but also the friction between the roller sleeve 14 and the material can be increased to better exert an effect on the material.

[0059] Among them, the body 13 can be made of a variety of materials. Exemplarily, the body 13 is made of 45# steel. In this way, the corrosion resistance of the body 13 can exceed ten years, the yield strength can reach 332 MPa, both the corrosion resistance and the yield strength are relatively strong, and the cost is relatively low. Therefore, it is beneficial to improve the corrosion resistance and yield strength of the roller 10 and reduce the cost of the roller 10.

[0060] In addition, the roller sleeve 14 can be made of a rubber material to achieve better protection and increase the friction effect. For example, in some embodiments, the roller sleeve 14 is made of polyether rubber. At this time, the hardness of the roller sleeve 14 is 55~85Ha, and the cost is relatively low. Therefore, it is possible to achieve better protection and increase the friction effect based on a relatively low cost.

[0061] In the foregoing embodiments, the roller sleeve 14 can be integrally formed with the body 13 to simplify the processing and manufacturing process and enhance the bonding strength between the roller sleeve 14 and the body 13, so that in the working process, the first section 11 can more reliably apply an action to the material.

[0062] Based on the roller 10 of the foregoing embodiments, the present application further provides a mechanical device, which includes a support member and also includes the roller 10 of any one of the embodiments. Among them, the mechanical device can be various devices including the roller 10 such as a gravure press. And, the roller 10 can be various rollers of the mechanical device, such as a guide roller or a traction roller, etc.

[0063] Next, the present application will be further introduced in combination with Figures 1-3 the embodiments of

[0064] In this embodiment, the roller 10 is a traction roller of a gravure press.

[0065] Among them, the intaglio printing press, also known as the gravure printing press, is a printing device that uses gravure plates for printing. It can widely use non-toxic water-based inks and alcohol-soluble inks to meet the standards of green environmental protection printing. Currently, water-based inks are basically used in the publishing field for intaglio printing; most water-based inks are used in the decoration field; in the flexible packaging field, although the proportion of solvent-based inks used is quite large, people are actively researching and developing water-based inks and alcohol-soluble inks that can meet environmental protection standards and have achieved gratifying results. Intaglio printing can truly reproduce the original manuscript effect, with rich, clear levels, thick ink layers, high ink color saturation, and bright and vivid colors. The media applicable to intaglio printing are very extensive, including PDC, PET, PE, NY, CPP, OPP, BOPP, composite films, and other films and papers with the same properties as the above materials. The intaglio printing press can also be attached with processes such as varnishing, laminating, coating, die-cutting, slitting, punching, and cross-cutting. With the continuous emergence of various paper packages, such as the frequent application of shopping bags, commodity bags, garbage bags, refrigerator fresh-keeping bags, etc., plastic flexible packaging is also widely used in handicraft packaging, household daily necessities packaging, clothing packaging, and pharmaceutical packaging. Various solid packaging boxes, liquid packaging boxes, cigarette packages, wine packages, etc. all require comprehensive processing by intaglio printing equipment.

[0066] The traction roller is an important component of the intaglio printing press, which is mainly used to traction the material film and perform traction and shaping on the material film. The two ends of the traction roller are connected to two points of the support member to achieve installation in the intaglio printing press. For different models of intaglio printing presses, the installation space on the support for installing the traction roller (i.e., the distance between the two points of the support member for connecting with the traction roller) is different.

[0067] In the related technology, the length of the traction roller is fixed and non-adjustable, and it cannot be flexibly applied to different models of intaglio printing presses.

[0068] In view of the above situation, the structure of the traction roller is improved in this embodiment.

[0069] As Figures 1-3 shown, in this embodiment, the roller 10 serving as the traction roller of the intaglio printing press includes a roller body 1, two bearings 4, two anti-disengagement members 3, and two locking mechanisms 2. The roller body 1 includes a first section 11 and two second sections 12.

[0070] Among them, the first section 11 is used to contact the material film to achieve the traction effect. As Figure 2 shown, in this embodiment, the first section 11 is cylindrical, with a hollow interior, and includes a body 13 and a roller sleeve 14 covering the outer surface of the body 13. The body 13 and the roller sleeve 14 are integrally formed and are made of 45# steel and polyether rubber respectively. In this way, while meeting the traction requirements, the manufacturing, use, and maintenance costs of the roller 10 can be reduced.

[0071] Two second segments 12 are disposed at two axial ends of the first segment 11 and are both movably disposed relative to the first segment 11. As Figure 2 shown, in this embodiment, the structures of the two second segments 12 are the same. Each includes a first end located in the first segment 11 and a second end located outside the first segment 11, and they are both slidably disposed in the first segment 11. In this way, the two second segments 12 slide in the first segment 11, so they can be telescopic, thereby changing the length of the roller body 1 and realizing the adjustment of the length of the roller 10.

[0072] Two bearings 4 correspond to the two second segments 12 one by one. They are respectively disposed at the second ends of the two second segments 12 and are used to connect with the support member to support the roller body 1 on the support member, thereby realizing the installation of the roller 10 on the support member. During use, the two bearings 4 are connected with the support member, thus completing the installation of the roller 10. In this embodiment, the bearing 4 is an N208E roller bearing, whose rated dynamic load Cr is greater than 33 KN and the cost is relatively low.

[0073] Since in this embodiment, two slidable second segments 12 are provided at two ends of the first segment 11, the length of the roller body 1 is adjustable, and the distance between the two bearings 4 is adjustable. Therefore, the roller 10 can adapt to installation spaces of different sizes. In this way, the use flexibility of the roller 10 can be effectively improved, the applicable range of the roller 10 can be expanded, and the roller 10 can be flexibly applied to intaglio printing machines of different models.

[0074] Two anti-disengagement members 3 correspond to the two second segments 12 one by one and are used to prevent the two second segments 12 from slipping off. As Figure 2 and Figure 3 shown, in this embodiment, the two anti-disengagement members 3 are respectively disposed at the first ends of the two second segments 12. Each anti-disengagement member 3 is in a plate shape, and the cross-sectional dimension thereof is larger than the dimension of the hole on the axial end face of the body 13 for the second end of the second segment 12 to extend out. Therefore, during the movement of the second segment 12, it can abut against the axial end face of the body 13 to stop and limit the second segment 12, preventing the second segment 12 from slipping out of the first segment 11.

[0075] Two locking mechanisms 2 correspond to the two second segments 12 one by one and are used to lock the two second segments 12 so that both of the two second segments 12 can be stably maintained at their corresponding positions after moving into place. As Figure 1 and Figure 2 shown, in this embodiment, the structures of the two locking mechanisms 2 are the same and each includes a plurality of ( Figure 2Taking three as an example, there are locking units 21. These multiple locking units 21 are arranged at intervals along the moving direction of the second section 12 (which is also the length direction and axial direction of the main body 13, the roller body 1, and the roller 10). And each locking unit 21 includes multiple locking members 22 arranged uniformly along the circumferential direction of the second section 12 (which is also the circumferential direction of the main body 13, the first section 11, the roller body 1, and the roller 10). Each locking member 22 is in a block shape and is rotatably arranged in the groove 15 on the second section 12 through a rotating shaft 23 to switch between a first position and a second position. The first position and the second position are perpendicular to each other. When in the first position, the length direction of the locking member 22 is along the radial direction of the second section 12 (which is also the radial direction of the main body 13, the first section 11, the roller body 1, and the roller 10). At this time, the locking member 22 extends outside the groove 15 so as to be connected to the axial end face of the main body 13 through a connecting member 24 such as a bolt, locking the second section 12 to the first section 11 to achieve the locking function. When in the second position, the length direction of the locking member 22 is along the axial direction of the second section 12 (which is also the axial direction of the main body 13, the first section 11, the roller body 1, and the roller 10). At this time, the locking member 22 is entirely received in the groove 15 and does not protrude from the groove 15. Therefore, it can prevent the locking member 22 from affecting the movement of the second section 12.

[0076] Based on the foregoing structural settings, during installation, according to the different sizes of the installation space for installing the traction roller on different models of gravure printers, the second section 12 can be pulled to drive the anti-disengagement member 3 to slide in the first section 11. After the second section 12 slides to the required position, the corresponding locking member 22 is rotated to rotate the locking member 22 from the second position to the first position, and then the locking member 22 is fixed to the axial end face of the first section 11 by using the connecting member 24, thereby completing the locking of the position of the second section 12 and realizing the adjustment of the overall length of the roller 10, so that the length of the roller 10 can adapt to the installation requirements of the corresponding installation space.

[0077] It can be seen that the roller 10 of this embodiment has a relatively low cost, can be flexibly applied to different models of gravure printers, has high use flexibility and a wide application range. Moreover, the on-machine test shows that the roller 10 of this embodiment has relatively stable tension and can effectively meet the requirements of the production process and production quality of the gravure printer.

[0078] The above are only exemplary embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
