Description

Technical Field

[0001] This utility model relates to the field of embossing machine technology, and more specifically, to a quick roller changing embossing device. Background Technology

[0002] In the field of paper processing and post-printing finishing, embossing equipment is one of the core pieces of equipment for enhancing the texture and visual effect of products. It is widely used in the production and processing of products such as playing cards, packaging boxes, greeting cards, and book covers. Its working principle is to use the squeezing action of one or more pairs of embossing rollers to press a preset texture (such as halftone, fabric texture, embossed texture, etc.) onto the surface of substrates such as paper and cardstock. This gives the product a stronger tactile feel and anti-counterfeiting identification. Especially in the production of playing cards, the quality of embossing directly affects the wear resistance, anti-slip properties, and user experience of the card surface, making it one of the key processes that determines product quality.

[0003] Playing card processing requires embossing equipment. To produce playing cards with different textures, the upper and lower embossing rollers need to be replaced. Existing embossing equipment often uses a fixed bolt connection for the embossing rollers, with the bearing housing being disassembled as a whole or locked by multiple sets of fasteners. Changing rollers not only requires disassembling bolts and other structures but also necessitates the use of lifting equipment. In particular, inserting the bearing of the new roller into the bearing housing is time-consuming, making the entire roller changing operation lengthy and affecting equipment processing efficiency. Therefore, we propose a quick-change roller embossing device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a quick roller-changing embossing device to solve the technical problems of cumbersome roller changing operation and long process time.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick roller-changing embossing device, including an installation mechanism, a roller-changing mechanism and a driving mechanism provided on the installation mechanism, the installation mechanism including a base plate and a fixing plate provided on the base plate, the roller-changing mechanism including symmetrically arranged roller-changing frames and a lifting assembly for driving the roller-changing frames to rise and fall, the lifting assembly having symmetrically arranged bearing seats, the bearing seats having a lower embossing roller and an upper embossing roller respectively, the roller-changing frame including a lower frame body and an upper frame body, a connecting rod being provided between the lower frame body and the upper frame body, and both the lower frame body and the upper frame body including a positioning part, a limiting part, a bending part and a cover plate part.

[0006] Preferably, conveying rollers are rotatably mounted at equal intervals between the fixed plates, and the conveying rollers are linked by pulleys and belts. A first motor for driving the conveying rollers is provided on the outer surface of the fixed plate.

[0007] Preferably, the lifting assembly includes a mounting frame disposed on a base plate, a hydraulic device is disposed at the top of the mounting frame, a mounting rod is disposed at the end of the hydraulic rod of the hydraulic device, and the end of the mounting rod is connected to the roller changing frame.

[0008] Preferably, the driving mechanism includes a mounting plate slidably mounted on the outer surface of the fixed plate, a first gear symmetrically arranged on the back of the mounting plate and meshing with each other, a second motor for driving the first gear is arranged on the front of the mounting plate, and the driving mechanism further includes a cylinder arranged on the outer surface of the fixed plate for driving the mounting plate to move.

[0009] Preferably, bearings are symmetrically arranged on the shafts of the lower embossing roller and the upper embossing roller, the bearings are located in bearing housings, and a second gear for driving is provided on the shafts of the lower embossing roller and the upper embossing roller, the second gear being meshed with the first gear.

[0010] Preferably, the length of the positioning part of the upper frame is half the length of the positioning part of the lower frame. The positioning part is horizontally arranged and has a moving groove. The tail of the moving groove is enlarged in a figure-eight shape. The limiting part is bent upward at 90 degrees and is located at the end of the positioning part. The tail of the limiting part is bent inward at 90 degrees. The bending part is bent outward at 90 degrees and is located at the beginning of the positioning part. The bending part is bent upward and then outward along the long axis. The cover plate is located at the end of the bending part and covers the bearing seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a combination structure of "roller changing frame + bearing seat" so that the bearing on the embossing roller shaft is directly embedded in the bearing seat. When changing rollers, there is no need to remove any bolts. The roller changing frame can be lifted and lowered by the lifting component to separate or connect the embossing roller and the bearing seat. This completely eliminates the time-consuming steps of bolt removal and installation. The roller changing process is simplified from the complicated process of "disassembly-hoisting-installation-tightening" to the efficient process of "lifting-pushing-hoisting-resetting". This significantly shortens the time of a single roller changing and is easy to operate, solving the problem of cumbersome operation and long process of current roller changing.

[0012] 2. This utility model also designs a lower and upper frame structure. The limiting part at the end of the positioning part is bent upwards at 90° and the tail is bent inwards. When the embossing roller is pushed to the tail of the positioning part, the limiting part can firmly lock the embossing roller to prevent it from slipping. This eliminates the need for manual positioning, reducing the safety risks of manual operation during roller changing. Simultaneously, the length of the positioning part of the upper frame is half that of the lower frame, causing the upper and lower embossing rollers to be staggered on the roller changing frame. This eliminates the need for multiple hoisting operations; the upper and lower embossing rollers can be removed and installed simultaneously using a single hoisting device. The design reduces the steps and time costs of changing rollers, making it particularly suitable for the needs of "multi-texture switching and high-frequency roller changing" in playing card production. The positioning parts of the lower and upper frames have a moving groove with an enlarged V-shape at the tail. The bearing of the new embossing roller can be quickly aligned and slid into the moving groove using the V-shaped opening, avoiding the problem of "difficult alignment" between the bearing and the bearing seat in traditional installation. Its cover plate automatically covers the bearing seat after the embossing roller is installed, which can prevent the bearing from falling off when the embossing roller rotates at high speed, avoid equipment failure or safety hazards, and effectively improve the efficiency of embossing roller replacement.

Detailed Implementation

[0015] like Figures 1 to 6As shown, this utility model relates to a quick roller-changing embossing device, including an installation mechanism 100, a roller-changing mechanism 200 provided on the installation mechanism 100, and a driving mechanism 300. The installation mechanism 100 includes a base plate 101 and a fixing plate 102 provided on the base plate 101. The roller-changing mechanism 200 includes symmetrically arranged roller-changing frames and a lifting assembly for driving the roller-changing frames to rise and fall. The lifting assembly is symmetrically provided with bearing seats 104. A lower embossing roller 105 and an upper embossing roller 106 are respectively provided on the bearing seats 104. The roller-changing frame includes a lower frame 204 and an upper frame 205. A connecting rod 208 is provided between the lower frame 204 and the upper frame 205. Both the lower frame 204 and the upper frame 205 include a positioning part 206, a limiting part 207, a bending part 209, and a cover plate part 210. This utility model allows for the separation or docking of the embossing roller and bearing seat 104 via the lifting and lowering of the roller changing frame, simplifying the roller changing process. The limiting part 207 prevents the embossing roller from slipping, and the staggered design of the upper and lower frames 204 supports simultaneous hoisting and roller changing. The figure-eight moving groove 2061 facilitates bearing alignment, and the cover plate 210 ensures safety. This significantly shortens the roller changing time, adapts to the needs of high-frequency roller changing, and improves the processing efficiency of the equipment.

[0016] Specifically, conveyor rollers 103 are rotatably mounted at equal intervals between the fixed plates 102. The conveyor rollers 103 are linked by pulleys and belts. A first motor 107 for driving the conveyor rollers 103 is provided on the outer surface of the fixed plates 102. The operation of the first motor 107 can make the conveyor rollers 103 rotate to convey the playing card paper to the upper and lower embossing rollers 105 for embossing.

[0017] Furthermore, the lifting assembly includes a mounting frame 201 mounted on the base plate 101. A hydraulic device 202 is mounted at the top of the mounting frame 201, and a mounting rod 203 is mounted at the end of the hydraulic rod of the hydraulic device 202. The end of the mounting rod 203 is connected to the roll changing frame. The mounting frame 201 provides a stable mounting support for the hydraulic device 202. The hydraulic device 202 moves the mounting rod 203 up and down by extending and retracting the hydraulic rod, thereby driving the roll changing frame to rise and fall, thus facilitating the roll changing operation.

[0018] It is worth noting that the drive mechanism 300 includes a mounting plate 302 slidably mounted on the outer surface of the fixed plate 102. Symmetrically arranged on the back of the mounting plate 302 are meshing first gears 304. A second motor 303 for driving the first gears 304 is arranged on the front of the mounting plate 302. The drive mechanism 300 also includes a cylinder 301 disposed on the outer surface of the fixed plate 102 for driving the movement of the mounting plate 302. The mounting plate 302 is slidably mounted and can move along the outer surface of the fixed plate 102 under the drive of the cylinder 301, thereby enabling the meshing or disengagement of the first gears 304 with the gears on the embossing roller shaft. The meshing of the first gears 304 ensures the synchronicity of power transmission. The second motor 303, as a power source, provides stable power for the rotation of the first gears 304, while the cylinder 301 provides reliable thrust for the movement of the mounting plate 302, ensuring smooth and efficient gear meshing and disengagement.

[0019] It is worth noting that bearings are symmetrically arranged on the shafts of both the lower embossing roller 105 and the upper embossing roller 106. The bearings are located within bearing housings 104. Second gears for driving are provided on the shafts of both rollers, and these second gears mesh with the first gear 304. The bearings support and mount the embossing rollers, facilitating their rotation. The meshing of the second gear with the first gear 304 transmits power from the drive mechanism 300 to the embossing rollers, ensuring that the lower embossing roller 105 and the upper embossing roller 106 can rotate synchronously in opposite directions, meeting the roller rotation requirements during substrate embossing.

[0020] It is worth noting that the length of the positioning part 206 of the upper frame 205 is half the length of the positioning part 206 of the lower frame 204. The positioning part 206 is horizontally arranged and has a moving groove 2061. The tail of the moving groove 2061 is enlarged in a figure-eight shape. The limiting part 207 is bent upward at 90 degrees and is located at the end of the positioning part 206. The tail of the limiting part 207 is bent inward at 90 degrees. The bending part 209 is bent outward at 90 degrees and is located at the beginning of the positioning part 206. The bending part 209 is bent upward and then outward along the long axis. The cover plate part 210 is located at the end of the bending part 209 and covers the bearing seat 104. The cover plate 210 is used to limit the bearing of the embossing roller to prevent it from dislodging from the bearing seat 104. When the roller needs to be changed, the upper frame 205 and the lower frame 204 are raised by the operation of the hydraulic device 202. The bending part 209 can rise and contact the shaft of the embossing roller, thereby lifting the embossing roller. The rising stops when the moving groove 2061 of the positioning part 206 is horizontal with the top surface of the bearing seat 104. At this time, the lower embossing roller 105 and the upper embossing roller 106 can be rolled onto the positioning part 206 by pushing, and their bearings are located in the moving groove 2061. Figure 6When pushed to the tail of the positioning part 206, the embossing roller can be limited by the limiting part 207. Because the upper frame 205 and the lower frame 204 are of different lengths, the lower embossing roller 105 and the upper embossing roller 106 are staggered, facilitating the simultaneous lifting and removal of both rollers by the hoisting equipment. When installing a new embossing roller, it is hoisted into the moving groove 2061, where the bearing is located at the tail. Because the tail of the moving groove 2061 is enlarged in a V-shape, it can... To facilitate the entry of the bearing of the new embossing roller into the moving groove 2061, the embossing roller can be moved towards the bearing seat 104 by pushing. When the bearing of the embossing roller is located on the bending part 209, the bearing of the bending part 209 is located directly above the bearing seat 104. At this time, the hydraulic device 202 works to lower the roller changing frame, and the bearing of the embossing roller can enter the bearing seat 104. The cover plate 210 can be placed on the bearing seat 104 to complete the replacement of the embossing roller.

[0021] Working Principle: This embodiment provides a quick-change roller embossing device. In use, firstly, the first motor 107 is started. The first motor 107, through the linkage of pulleys and belts, drives the conveyor rollers 103, which are equidistantly mounted between the fixed plates 102, to rotate. The conveyor rollers 103 smoothly transport the substrate, such as playing card paper, to be embossed between the lower embossing roller 105 and the upper embossing roller 106. Next, the cylinder 301 in the drive mechanism 300 is started. The cylinder 301 pushes the mounting plate 302, which is slidably mounted on the outer surface of the fixed plate 102, to move. This causes the first gear 304, symmetrically arranged and meshing with each other on the back of the mounting plate 302, to precisely mesh with the second gears on the shafts of the lower embossing roller 105 and the upper embossing roller 106. Then, the second motor 303 is started. The first gear 304 is driven to rotate by the 303 motor, which in turn drives the lower embossing roller 105 and the upper embossing roller 106 to rotate synchronously in opposite directions through gear meshing. At this time, the substrate material is pressed by the rotating lower embossing roller 105 and upper embossing roller 106, and the surface is pressed with a preset texture, completing the embossing process. When it is necessary to change to an embossing roller with a different texture, the second motor 303 is turned off first, and the control cylinder 301 drives the mounting plate 302 to reset, so that the first gear 304 is separated from the second gear. Then, the hydraulic device 202 at the top of the mounting frame 201 in the roller changing mechanism 200 is started. The hydraulic rod of the hydraulic device 202 is shortened, and the roller changing frame (composed of the lower frame 204, the upper frame 205 and the connecting rod 208) is raised through the mounting rod 203. The roller changing frame rises. During the process, the bending part 209 contacts the shafts of the lower embossing roller 105 and the upper embossing roller 106 and lifts them up until the moving groove 2061 of the positioning part 206 is level with the top surface of the bearing seat 104. At this time, the hydraulic equipment 202 stops. The operator pushes the lower embossing roller 105 and the upper embossing roller 106 so that the bearings on their shafts roll along the moving groove 2061 to the tail of the positioning part 206. The limiting part 207 limits the embossing roller to prevent it from slipping. Since the length of the positioning part 206 of the upper frame 205 is half the length of the positioning part 206 of the lower frame 204, the lower embossing roller 105 and the upper embossing roller 106 will be staggered, which makes it convenient to use hoisting equipment to hoist and remove the old embossing roller at the same time. When installing the new embossing roller, the new embossing roller is hoisted to the positioning part 206. At the tail end, the bearing on the new embossing roller shaft smoothly enters the moving groove 2061 by utilizing the V-shaped enlargement structure at the tail end of the moving groove 2061. This pushes the new embossing roller to move along the moving groove 2061 towards the bearing seat 104. When the shaft of the new embossing roller moves to the bending part 209, the bearing is exactly above the bearing seat 104. At this time, the hydraulic device 202 is activated to retract the hydraulic rod, driving the roller changing frame to descend. The bearing on the new embossing roller shaft then falls into the bearing seat 104. At the same time, the cover plate 210 covers the bearing seat 104 to limit the bearing and prevent it from falling off. Finally, the control cylinder 301 pushes the mounting plate 302 to re-mesh the first gear 304 with the second gear on the new embossing roller shaft, and the equipment can be restarted for embossing processing.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
