Description

Technical Field

[0001] This utility model relates to the field of embossing, specifically to embossing wheels. Background Technology

[0002] In the production and processing of PVC film, embossing rollers are widely used to imprint various patterns on the film surface. Different patterns are pressed on PVC film according to different requirements. Embossing rollers are a commonly used tool for embossing. Embossing rollers are suitable for pressing concave and convex patterns on plastic sheets, films, aluminum foil, leather, glass, paper and other materials to improve the surface aesthetics of products, enhance anti-counterfeiting, and protect trademarks.

[0003] A search revealed an existing patent (application number: 202122591446.4) that discloses an embossing roller for PVC film embossing. The roller body includes an embossing roller shaft and an embossing roller cylinder. The outer surface of the embossing roller shaft is provided with a connecting roller, and the outer surface of the connecting roller cylinder is provided with several connecting protrusions. While this patented technology effectively meets the needs of changing different embossing patterns and improves the stability of the embossing roller cylinder, facilitating embossing applications, it suffers from several drawbacks. Changing the embossing pattern requires replacing the entire embossing roller, which is not only costly and inconvenient, reducing production efficiency, but also necessitates disassembling the entire supporting roller frame before installation, consuming considerable installation time.

[0004] Therefore, those skilled in the art have provided embossing wheels to solve the problems mentioned in the background section. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides an embossing wheel that solves the problems of high cost and inconvenience in replacing the entire embossing roller when changing the embossing pattern, as well as the need to disassemble the entire supporting roller frame before disassembling and installing the embossing roller, which consumes a lot of installation time.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An embossing wheel includes a fixed plate, with electric push rods fixedly connected to both ends of the bottom of the fixed plate. A support block is fixedly connected to the output shaft of the electric push rod. A fixed column is fixedly connected between the two support blocks. A fixed support plate is fixedly connected to one end of the fixed column, and a movable support plate is slidably connected to the outer side of the other end of the fixed column. An inner roller is provided at the bottom of the fixed column. A first fixed block and a second fixed block are fixedly connected to both ends of the inner roller, respectively. A fixed turntable is fixedly connected to the side of the first fixed block. An annular groove is provided on the side of the fixed support plate and rotatably connected to the fixed turntable. A patterned sleeve is provided on the outer side of the inner roller. An annular groove is provided on the side of the second fixed block and rotatably connected to a rotating ring. A second limiting shell is fixedly connected to the end of the patterned sleeve away from the first limiting shell.

[0010] With the above technical solution, when changing the embossing pattern of the embossing roller, only the pattern sleeve on the outer side of the inner roller needs to be replaced to make the device emboss different patterns. This solves the problem that changing the embossing pattern of the embossing roller requires replacing the entire embossing roller, which is not only costly but also inconvenient to operate and reduces production efficiency.

[0011] Furthermore, two positioning rods are fixedly connected to the side of the fixed support plate. Threaded holes are provided inside the end of the positioning rod away from the fixed support plate and inside the movable support plate. Bolts are threadedly connected inside the threaded holes of the movable support plate.

[0012] Through the above technical solution, the positioning rod can limit and fix the movable support plate. When changing the embossed pattern of the device, the pattern can be changed without disassembling the entire roller frame.

[0013] Furthermore, a first limiting shell is fixedly connected to one end of the patterned sleeve, and four fixed limiting blocks are fixedly connected to the outside of the first fixing block. A limiting groove adapted to the fixed limiting block is opened at the end of the first limiting shell away from the patterned sleeve.

[0014] Through the above technical solution, the fixed limiting block can limit the position of the first limiting shell, prevent the pattern sleeve from shifting, and after the first fixed block rotates, the fixed limiting block can drive the first limiting shell to rotate.

[0015] Furthermore, two threaded holes are provided inside the rotating ring and the second fixing block, and bolts are threaded into the threaded holes of the rotating ring;

[0016] Through the above technical solution, the bolt can limit the rotation of the swivel ring, preventing it from rotating. The swivel ring can simultaneously move multiple movable limit blocks, thereby limiting the second limit shell.

[0017] Furthermore, the side of the second fixed block is provided with a sliding groove and four movable limiting blocks are slidably connected thereto. The movable limiting blocks are rotatably connected to the rotating ring with a connecting rod. The interior of the second limiting shell is provided with a limiting groove that is adapted to the second movable limiting block.

[0018] Through the above technical solution, multiple movable limit blocks can be moved synchronously at the same time by means of the rotating ring and connecting rod. The movable limit blocks can limit the second limit shell, prevent the second limit shell from moving, and prevent the patterned sleeve from sticking to the inner roller.

[0019] Furthermore, a positioning block is fixedly connected to the side of the second fixed block, and a movable turntable is rotatably connected to the side of the movable support plate. The side of the movable turntable is provided with a groove that matches the positioning block.

[0020] Through the above technical solution, the positioning block can enter the interior of the movable turntable, thereby enabling the movable turntable to support the other end of the inner roller and rotate with the inner roller when the inner roller rotates.

[0021] Furthermore, the inner roller has a through hole and a heating rod is fixedly connected to it. The first fixing block, the fixed turntable, and the fixed support plate all have through holes. The input end of the heating rod is fixedly connected to a cable.

[0022] Through the above technical solution, the heating rod can heat the inner roller, thereby heating the patterned sleeve, which in turn imprints the film. The through holes inside the first fixing block, the fixing turntable, and the fixing support plate can facilitate the entry and exit of the cable and also dissipate heat from the heating rod.

[0023] Furthermore, a support frame is fixedly connected to the side of the fixed support plate, a motor is fixedly connected to the inner side of the support frame, a gear is fixedly connected to the output shaft of the motor, and a gear tooth that matches the gear is fixedly connected to the outer side of the fixed turntable.

[0024] Through the above technical solution, the motor can provide power to the gear, which can make the fixed turntable rotate, thereby making the inner roller rotate, so that the device can complete the printing.

[0040] Please see Figure 4 , Figure 5In this embodiment, the embossing wheel has two positioning rods 7 fixedly connected to the side of the fixed support plate 5. Threaded holes are provided inside the end of the positioning rod 7 away from the fixed support plate 5 and inside the movable support plate 6.

A gear tooth that matches the gear 25 is fixedly connected to the outer side of the fixed turntable 10.

[0041] In this embodiment, an embossing roller is described. It should be noted that the arrangement of the inner roller 8, pattern sleeve 11, first fixed block 9, first limiting shell 12, fixed limiting block 13, movable limiting block 16, second fixed block 14, second limiting shell 18, rotating ring 15, and movable limiting block 16 allows the device to emboss different patterns simply by replacing the pattern sleeve 11 on the outer side of the inner roller 8 when changing the embossing pattern. This solves the problem of having to replace the entire embossing roller when changing its embossing pattern. The previous method not only had high costs and was inconvenient to operate, reducing production efficiency, but also solved the problems of high cost and inconvenient operation, which reduced production efficiency. By setting up a fixed column 4, a fixed support plate 5, a movable support plate 6, a positioning rod 7, a fixed turntable 10, a positioning block 19, and a movable turntable 20, the device can replace the pattern sleeve 11 by simply turning two bolts to disassemble the movable support plate 6. This allows the device to emboss different patterns and solves the problem that the entire supporting roller frame needs to be disassembled first when disassembling and installing the embossing roller, which consumes a lot of installation time.

[0042] The working principle of the above embodiment is as follows: When it is necessary to change the printed pattern of the device, the operator rotates the bolt on the side of the movable support plate 6 to disengage the bolt from the movable support plate 6 and the positioning rod 7, thereby canceling the limitation of the positioning rod 7 on the movable support plate 6. Then, the operator pulls the movable support plate 6 to move it outside the fixed column 4, thereby disengaging the positioning block 19 from the movable turntable 20. After moving the movable support plate 6, the operator rotates the movable support plate 6 to rotate through the fixed column 4, thereby canceling the obstruction of the inner roller 8. Then, the operator rotates the bolt inside the rotating ring 15 to cancel the connection between the rotating ring 15 and the fixed column 4. After the connection between the second fixed block 14 is removed, rotate the rotating ring 15 to move the connecting rod 17. After the connecting rod 17 moves, it pulls the movable limiting block 16 to move, thereby disengaging the movable limiting block 16 from the second limiting shell 18. Then, the second limiting shell 18 can be pulled to move the patterned sleeve 11, thereby disengaging the patterned sleeve 11 from the inner roller 8. Then, take out the patterned sleeves 11 with different patterns and place them on the outside of the inner roller 8. When placing them, make the first limiting shell 12 contact the inner roller 8 first, and then the first limiting shell 12 enters the outside of the first fixed block 9. At this time, the fixed limiting block 13 and the first limiting shell 12 are connected. The internal limiting groove contacts, thus initially limiting the first limiting shell 12. After the limiting is completed, the second limiting shell 18 is located outside the second fixing block 14. Then, the rotating ring 15 can be rotated to allow the movable limiting block 16 to enter the interior of the second limiting shell 18, thereby limiting the second limiting shell 18. After that, the rotating ring 15 can be limited by bolts, thus completing the installation of the patterned sleeve 11. After the patterned sleeve 11 is installed, the movable support plate 6 can be rotated. After rotation, the movable support plate 6 is pushed to allow the positioning block 19 to enter the interior of the movable turntable 20. Then, the bolts are inserted into the movable support plate 6. The internal mechanism connects the movable support plate 6 and the positioning rod 7 to fix the movable support plate 6. Then, the device can be used to print on the film. During printing, the fixed plate 1 is fixed to the external conveying device. Then, the height of the pattern sleeve 11 is adjusted by the electric push rod 2 to make it fit the film. Then, the heating rod 21 is started by the cable 22 to heat the inner roller 8, thereby raising the temperature of the pattern sleeve 11. Then, the motor 24 is started to rotate the gear 25. After the gear 25 rotates, the fixed turntable 10 rotates, thereby causing the inner roller 8 to drive the pattern sleeve 11 to rotate, thus printing on the film.
