Description

Technical Field

[0001] The invention belongs to the technical field of embossing equipment and relates to an embossing roller. Background Art

[0002] Plastic ocean pedals are widely used in water facilities such as docks, pontoons, and platforms. At the same time, due to their corrosion resistance such as acid and alkali, they can be used as anti-slip pads in the industrial field. In the production process of plastic ocean pedals, first, a plain board is made through an extrusion mold molding process, and then an embossing roller is needed. After the plain board is formed, the embossing roller is heated and pressed on the plain board surface of the plastic ocean pedal. The pattern on the embossing roller is used to make various expected patterns on the board surface to increase the anti-slip effect.

[0003] For example, the application number is 202321375247.2, which is a kind of anti-skid hot pressing roller, including a heat transfer tube and an anti-skid layer, a rotating shaft is coaxially fixedly connected at the inner circumference of the heat transfer tube, a plurality of heating grooves are provided through the heat transfer tube, a heating rod is detachably connected to the heat transfer tube in the heating grooves, the anti-skid layer is coaxially sleeved on the outer circumference of the heat transfer tube, a plurality of limit strips are fixedly connected to the outer circumference of the heat transfer tube along its length direction, a plurality of limit strips are provided through the inner circumference of the anti-skid layer, a plurality of limit strips are respectively inserted into the plurality of limit strips, and the limit strips are slidably matched with the limit strips along the length direction of the heat transfer tube, and the limit strips are provided with locking components for fixing the anti-skid layer.

[0004] During the production process, since the extrusion equipment is fixed and the position of the extruded product is fixed, the position of the product cannot be adjusted. The pattern actually embossed by the embossing roller of the above scheme will be offset, resulting in poor embossing quality, causing obvious changes in the product appearance, and even a significant decrease in the anti-slip effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and propose an embossing roller. The technical problem to be solved by the present invention is: how to ensure the embossing quality of the embossing roller.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] An embossing roller comprises a columnar roller body and a cylindrical roller sleeve with an embossed pattern on the outer peripheral wall, both ends of the roller body are provided with mounting shafts coaxial with the roller body, and the characteristic is that the roller sleeve is slidably sleeved outside the roller body along the length direction of the roller body, the length of the roller sleeve is greater than the length of the roller body and both ends protrude outward from the two ends of the roller body, and end covers are slidably sleeved on the two mounting shafts respectively, and the two end covers are respectively correspondingly provided with axial positioning at the two ends of the roller sleeve, and the two mounting shafts are rotatably connected with adjusting members capable of pushing the corresponding end covers to move along the length direction of the roller body, and one of the end covers is fixed to the roller body by a fastener.

[0008] During installation, first put the roller sleeve on the roller body, and then put the two end covers axially positioned on the two ends of the roller sleeve. According to the requirements of the embossing position, the roller sleeve can be moved along the length direction of the roller body by rotating the adjusting pieces at both ends. After the roller sleeve moves to the determined position, the roller sleeve is positioned on the roller body by fasteners; during the embossing process, the rotation of the roller body drives the roller sleeve to rotate to realize the embossing operation of the plastic ocean pedal. Firstly, by making the length of the roller sleeve longer than the length of the roller body and protruding both ends outward from the two ends of the roller body, the roller sleeve has a certain axial movement space, so that the roller sleeve can move axially relative to the roller body, and the end covers are axially positioned at the two ends of the roller sleeve so that the roller sleeve can move along when the adjusting part pushes the end covers. The end covers serve as transmission middle pieces between the adjusting part and the roller sleeve to realize indirect force transmission, which can effectively reduce the friction between the roller sleeve and the roller body and reduce the wear of the roller sleeve. The volume of the roller sleeve is relatively large, and the end covers can greatly simplify the processing of the two ends of the roller sleeve and reduce the manufacturing cost of the roller sleeve. The roller sleeve is positioned by fasteners to avoid the roller sleeve from shifting relative to the roller body during embossing, and the roller sleeve is axially adjusted to improve adaptability, thereby ensuring the embossing quality of the embossing roller. Secondly, the axial position of the roller sleeve is adjusted instead of positioning the roller sleeve on the roller body and then moving the roller body. This is because compared with moving the entire roller body, local adjustment of the roller sleeve is more conducive to achieving subtle adjustment of the embossing effect and simplifies the adjustment steps. The roller sleeve is detachably connected to the roller body, so the installation operation of the roller sleeve is inevitable. At this time, further adjustment of the roller body will increase the difficulty of adjustment and reduce the accuracy of adjustment. Local operation reduces the impact on the roller body, greatly improves maintenance efficiency, and further ensures the embossing quality of the embossing roller.

[0009] In the above-mentioned embossing roller, the two adjusting parts each have an annular rotating part and a plurality of rod-shaped pushing parts arranged at intervals in the circumferential direction of the rotating part, the outer circumferences of the two mounting shafts have external threads, and the inner circumferential walls of the two rotating parts have internal threads matching the external threads of the corresponding mounting shafts. The setting of the pushing part can facilitate the operation and rotation, improve the flexibility of adjustment, and realize fine axial displacement adjustment through transmission matching of the thread, effectively control the embossing effect of the embossing pattern, improve the accuracy of adjustment, and further ensure the embossing quality of the embossing roller.

[0010] In the above-mentioned embossing roller, there is a guide structure between the roller sleeve and the roller body, and the guide structure includes a guide groove provided on the outer wall of the roller body and a convex strip provided on the inner circumferential wall of the roller sleeve, the guide groove penetrates the roller body along the length direction of the roller body, and the convex strip is provided along the length direction of the roller sleeve and slides with the guide groove. The sliding cooperation of the convex strip and the guide groove provides an external guide for the axial movement of the roller sleeve, increases the consistency of the direction and the stability of the movement of the roller sleeve when the roller sleeve moves, and is conducive to high-precision adjustment of the axial movement of the roller sleeve. At the same time, the cooperation of the convex strip and the guide groove enables the roller sleeve to be set outside the roller body to limit the roller sleeve circumferentially, so as to prevent the roller sleeve from rotating relative to the roller body.

[0011] In the above-mentioned embossing roller, the guide structure also includes a plurality of guide holes arranged in the roller body and a plurality of guide posts arranged on one of the end covers, the plurality of guide holes are arranged at intervals and all penetrate the roller body along the length direction of the roller body, the plurality of guide posts are slidably arranged in the plurality of guide holes corresponding to each other, and the other end cover is fixed to the guide post by bolts arranged along the length direction of the guide post. The sliding cooperation of the guide holes and the guide posts forms an inner guide, which further increases the consistency of the direction and the stability of the movement of the roller sleeve when the roller sleeve moves, and improves the matching accuracy of the roller sleeve and the roller body. In addition, when the roller body drives the roller sleeve to rotate, the inner guide can reduce the torque generated by the rotation, and can also suppress its angular swing during the rotation process, increase the stability during the rotation process, and ensure the embossing effect. A double inner and outer guide structure is formed by combining the inner guide and the outer guide. This composite guide method ensures the stability of the axial movement, so that the adjustment accuracy of the roller sleeve can be higher and the power consumption during the rotation process can be effectively reduced, which is conducive to the embossing roller to maintain good dynamic balance characteristics during the rotation process, reduce vibration noise, and improve the energy efficiency performance of the embossing roller.

[0012] In the above-mentioned embossing roller, the fasteners are two bolts, and the two fasteners pass through the end cover without the guide column and are threadedly connected to the roller body. Using bolts as fasteners has a simple structure and convenient operation, and can ensure the connection strength between the end cover and the roller body, and ensure the stability of the embossing process. The setting of the double fasteners can better resist the vibration load and increase the service life of the embossing roller.

[0013] In the above-mentioned embossing roller, the end cap has a convex ring on the end face opposite to the corresponding adjusting member, and the adjusting member has a ring-shaped abutting portion that can abut against the convex ring. During the adjustment process, the adjusting member rotates and moves along the thread in the length direction of the installation shaft, abuts against the corresponding end cap and pushes the end cap to move during the movement. During the pushing process, the adjusting member is in a rotating state, and friction is formed between the end cap. The setting of the convex ring reduces the contact area between the adjusting member and the end cap to reduce friction resistance, improve the flexibility of operating the adjusting member, and is conducive to improving the adjustment accuracy. It can also reduce the degree of wear between the adjusting member and the end cap.

[0014] In the above-mentioned embossing roller, the side of the adjusting member opposite to the corresponding end cap is an arc edge. During the adjustment process, the adjusting member rotates and moves along the thread in the length direction of the installation shaft, and during the movement, it abuts against the corresponding end cap and pushes the end cap to move. During the pushing process, the adjusting member is in a rotating state, and friction is formed between the adjusting member and the end cap. The arc edge of the adjusting member can be used to reduce the contact area between the adjusting member and the end cap to reduce friction resistance, improve the flexibility of operating the adjusting member, improve the responsiveness of the embossing roller adjustment, help improve the adjustment accuracy, and reduce the wear between the adjusting member and the end cap.

[0015] In the above-mentioned embossing roller, the end cap with the guide column is connected with a bolt threadedly connected to the convex strip. When installing, the end cap with the guide column is fixed to the roller sleeve to facilitate the positioning and fixing of the other end cap, and at the same time, the connection strength between the end cap and the roller sleeve can be improved, and the structural stability and reliability can be increased.

[0016] In the above-mentioned embossing roller, the roller sleeve is an integrated type. The integrated sleeve can improve the convenience of installation.

[0017] In the above-mentioned embossing roller, the roller sleeve is a combined type. The combined sleeve is easy to produce and has more pattern selectivity.

[0018] Whether it is an integrated type or a combined type, the roller sleeve can be clamped by the end covers at both ends, which has good compatibility with the end covers, improves the versatility and flexibility of the embossing roller to adapt to different embossing requirements, and enhances the adaptability of the embossing roller.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. By making the length of the roller sleeve longer than the length of the roller body, the roller sleeve has a certain axial movement space, so that the roller sleeve can move axially relative to the roller body. The stability of the movement of the roller sleeve during the adjustment process is ensured by the guide structure. The movement accuracy of the roller sleeve is improved by pushing the roller sleeve to move through the adjusting member, which is convenient for fine-tuning the position of the roller sleeve. At the same time, the roller sleeve is positioned by fasteners to avoid the roller sleeve from shifting relative to the roller body during the embossing process, thereby ensuring the embossing quality of the embossing roller.

[0021] 2. The setting of the push part can facilitate the operation of rotation and improve the flexibility of adjustment. Through the transmission cooperation of the thread, it can realize fine axial displacement adjustment, effectively control the embossing effect of the embossed pattern, and improve the accuracy of adjustment.

[0022] 3. An internal and external double guide structure is formed by combining the internal guide and the external guide. This composite guide method ensures the stability of the axial movement, enables the roller sleeve to have a higher adjustment accuracy and effectively reduces the power consumption during the rotation process, which is beneficial for the embossing roller to maintain a good dynamic balance during the rotation process, reduce vibration noise, and improve the energy efficiency of the embossing roller.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to the following embodiments.

[0030] Embodiment 1

[0031] like Figures 1 to 3As shown, an embossing roller comprises a columnar roller body 1 and a cylindrical roller sleeve 2 with an embossed pattern on the outer peripheral wall. Both ends of the roller body 1 have a mounting shaft 11 coaxial with the roller body 1. Bearings 9 are fixedly mounted on the two mounting shafts 11. The roller sleeve 2 can be an integrated type or a combined type, which improves the versatility and flexibility of the embossing roller to meet different embossing requirements and enhances the adaptability of the embossing roller. A heat conduction hole 14 is penetrated in the roller body 1 along the length direction, and a heat conduction rod is inserted in the heat conduction hole 14. A collector ring 8 is sleeved on the end of one of the mounting shafts 11. Two bearings 9 can be slid up and down and connected to the bracket so that the roller body 1 can move up and down. The bracket is not drawn in the attached figure. The bearing 9 and the bracket enable the roller body 1 to move up and down without affecting the rotation of the roller body 1, which is a prior art. This embodiment is described only to explain the working principle of the embossing roller in detail. The length of the roller sleeve 2 is greater than the length of the roller body 1 and both ends protrude outward from the two ends of the roller body 1. A guide structure is provided between the roller sleeve 2 and the roller body 1. The roller sleeve 2 is slidably sleeved on the outside of the roller body 1 along the length direction of the roller body 1 through the guide structure. End covers 3 are slidably sleeved on the two mounting shafts 11 respectively. The two end covers 3 are respectively positioned at the two ends of the roller sleeve 2 corresponding to the cover settings. Adjusting parts 4 that can push the corresponding end covers 3 to move along the length direction of the roller body 1 are rotatably connected to the two mounting shafts 11, and one of the end covers 3 is fixed to the roller body 1 by a fastener 5.

[0032] The two adjusting members 4 each have an annular rotating portion 41 and a plurality of rod-shaped pushing portions 42 spaced apart on the circumference of the rotating portion 41. The outer circumferences of the two mounting shafts 11 have external threads, and the inner circumferential walls of the two rotating portions 41 have internal threads that match the external threads of the corresponding mounting shafts 11. The setting of the pushing portion 42 can facilitate the operation of rotation, improve the flexibility of adjustment, and achieve fine axial displacement adjustment through transmission matching with the threads, effectively control the embossing effect of the embossed pattern, and improve the accuracy of adjustment.

[0033] The guide structure is a composite guide structure formed by combining an inner guide and an outer guide, wherein the outer guide comprises a guide groove 12 provided on the outer wall of the roller body 1 and a convex strip 21 provided on the inner peripheral wall of the roller sleeve 2, the guide groove 12 penetrates the roller body 1 along the length direction of the roller body 1, the convex strip 21 is provided along the length direction of the roller sleeve 2 and slidably cooperates with the guide groove 12, and the outer guide has the function of guiding and can limit the roller sleeve 2 circumferentially during installation; the inner guide comprises a plurality of guide holes 13 provided in the roller body 1 and a plurality of guide posts 6 provided on one of the end covers 3, the plurality of guide holes 13 are provided at intervals and penetrate the roller body 1 along the length direction of the roller body 1, the plurality of guide posts 6 are slidably provided in the plurality of guide holes 13 in a one-to-one correspondence, and the other end cover 3 is fixed to the guide post 6 by bolts provided along the length direction of the guide post 6, and the inner guide can reduce the torque generated by the rotation, and also suppress its angular swing during the rotation, increase the stability during the rotation, and ensure the embossing effect. Through such a composite guiding method of internal and external double guiding structure, the consistency of direction and stability of movement of the roller sleeve 2 are increased, the matching accuracy of the roller sleeve 2 and the roller body 1 is improved, and the power consumption during the rotation process is effectively reduced, which is beneficial for the embossing roller to maintain good dynamic balance characteristics during the rotation process, reduce vibration noise, and improve the energy efficiency performance of the embossing roller.

[0034] There are two fasteners 5, which are bolts. The two fasteners 5 pass through the end cap 3 without the guide column 6 and are threadedly connected to the roller body 1. The structure is simple and the operation is convenient. At the same time, the connection strength between the end cap 3 and the roller body 1 can be ensured, and the stability of the embossing process can be ensured. The setting of the double fasteners 5 can better resist the vibration load and improve the service life of the embossing roller. The end cap 3 with the guide column 6 is connected to the bolt threadedly connected to the convex strip 21. During installation, the end cap 3 with the guide column 6 is fixed to the roller sleeve 2 to facilitate the positioning and fixing of the other end cap 3. At the same time, the connection strength between the end cap 3 and the roller sleeve 2 can be improved, and the structural stability and reliability can be increased. In this embodiment, whether the roller sleeve 2 is an integrated type or a combined type, the roller sleeve 2 can be clamped by the end caps 3 at both ends using the guide columns 6. It has good compatibility, improves the versatility and flexibility of the embossing roller to adapt to different embossing requirements, and enhances the adaptability of the embossing roller.

[0035] Combination Figure 4The end cover 3 mentioned above has a convex ring 31 on the end surface opposite to the corresponding adjusting member 4, and the adjusting member 4 has an annular abutting portion 411 that can abut against the convex ring 31. During the adjustment process, the adjusting member 4 rotates and moves along the thread in the length direction of the installation shaft 11. During the movement, it abuts against the corresponding end cover 3 and pushes the end cover 3 to move. During the pushing process, the adjusting member 4 is in a rotating state, and friction is formed between the end cover 3. The setting of the convex ring 31 reduces the contact area between the adjusting member 4 and the end cover 3, so as to reduce the friction resistance, improve the flexibility of operating the adjusting member 4, and is conducive to improving the adjustment accuracy, and can reduce the wear between the adjusting member 4 and the end cover 3.

[0036] Embodiment 2

[0037] The structure of the embossing roller is basically the same as that of the first embodiment. The difference is that Figure 5 As shown, the side of the adjusting member 4 opposite to the corresponding end cover 3 is an arc edge 412. During the adjustment process, the adjusting member 4 rotates and moves along the thread in the length direction of the mounting shaft 11. During the movement, it abuts against the corresponding end cover 3 and pushes the end cover 3 to move. During the pushing process, the adjusting member 4 is in a rotating state, and friction is formed between the end cover 3. The arc-shaped edge of the adjusting member 4 can be used to reduce the contact area between the adjusting member 4 and the end cover 3 to reduce the friction resistance, improve the flexibility of operating the adjusting member 4, improve the responsiveness of the embossing roller adjustment, help improve the adjustment accuracy, and can reduce the degree of wear between the adjusting member 4 and the end cover 3.

[0038] During installation, the roller sleeve 2 is first sleeved on the roller body 1, and then the two end covers 3 are set and positioned at the two ends of the roller sleeve 2. According to the requirements of the embossing position, the roller sleeve 2 is moved along the length direction of the roller body 1 under the guidance of the guide structure by rotating the adjusting members 4 at both ends. After the roller sleeve 2 moves to a determined position, the roller sleeve 2 is positioned on the roller body 1 by the fastener 5. During the embossing operation, the extrusion equipment first extrude the formed plastic marine board, and the embossing roller moves downward and rotates to drive the roller sleeve 2 to rotate. During the embossing process, the collector ring 8 provides electrical energy to the heating rod 7 through the carbon brush to heat the heating rod 7, and then conducts the heat to the roller sleeve 2 to realize the embossing operation of the plastic marine pedal.

[0039] The present invention makes the length of the roller sleeve 2 longer than the length of the roller body 1 so that the roller sleeve 2 has a certain axial movement space, so that the roller sleeve 2 can move axially relative to the roller body 1, and ensures the stability of the movement of the roller sleeve 2 and the consistency of the direction during the adjustment process through the guide structure, and then promotes the movement of the roller sleeve 2 through the adjustment member 4 to improve the movement accuracy of the roller sleeve 2, so that the position of the roller sleeve 2 can be fine-tuned, and the end cover 3 is axially positioned at both ends of the roller sleeve 2 so that the roller sleeve 2 can move with the adjustment member 4 when the adjustment member 4 pushes the end cover. The end cover 3 is used as a transmission intermediate piece between the adjustment member 4 and the roller sleeve 2 to realize indirect force transmission, which can effectively reduce the friction between the roller sleeve 2 and the roller body 1 and reduce the wear of the roller sleeve 2. The volume of the roller sleeve 2 is relatively large. The end cover 3 can greatly simplify the processing of the two ends of the roller sleeve 2, reduce the manufacturing cost of the roller sleeve 2, and position the roller sleeve 2 through the fastener 5 to avoid the roller sleeve 2 from offsetting relative to the roller body 1 during the embossing process, thereby ensuring the embossing quality of the embossing roller. Secondly, the axial position of the roller sleeve 2 is adjusted instead of positioning the roller sleeve 2 on the roller body 1 and then moving the roller body 1 because compared with moving the entire roller body 1, local adjustment of the roller sleeve 2 is more conducive to achieving subtle adjustment of the embossing effect and simplifies the adjustment steps. The roller sleeve 2 is detachably connected to the roller body 1, so the installation operation of the roller sleeve 2 is inevitable. At this time, further increasing the adjustment of the roller body 1 will increase the difficulty of adjustment and reduce the accuracy of adjustment. Local operation reduces the impact on the roller body 1, greatly improves maintenance efficiency, and further improves the embossing quality of the embossing roller.
