[0002] Printing rollers, also known as steel rollers, are an important component of printing presses. They are used to print on the materials to be printed. Printing rollers are typically installed on a shaft using bolts. However, this traditional installation method has drawbacks. After the roller is fitted onto the shaft, the surface of the shaft and the inner wall of the roller are relatively smooth, allowing the roller to rotate freely on the shaft. This makes it difficult to align the screw holes on the roller with those on the shaft. Consequently, during installation, the operator needs to constantly adjust the roller until the screw holes are aligned, extending the roller replacement time and reducing replacement efficiency.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a snap-fit ​​structural design. The printing roller is connected and fixed to the shaft in a snap-fit ​​manner, which allows the printing roller and the shaft to be quickly connected together. This prevents the printing roller from moving freely on the shaft when installing bolts later. The printing roller and the shaft can be quickly installed together with bolts, ensuring that the printing roller can be put into use quickly and providing convenience for users.

[0014] 2. This utility model features bolt holes and fastening bolts. The bolt holes are used to insert and install the fastening bolts. During installation, the fastening bolts are inserted from the outside of the end block until they are inserted into the corresponding bolt holes. Then, the fastening bolts are tightened to fix the roller parts in the bolt holes. This further secures the replaced roller parts, ensures the stability of the roller parts printing operation, and provides convenience for users.

[0015] 3. This utility model incorporates a stop block, which is used to block and limit the movement of the inner support and roller components, ensuring that the roller components and inner support can be accurately installed in the set position, thus providing convenience for users' work.

[0016] 4. This utility model, through the setting of a synchronous pulley and a mounting bracket, uses a synchronous pulley to drive a synchronous pulley to a synchronous pulley. The synchronous pulley and the synchronous pulley are driven by a synchronous belt. In this way, when the stepper motor starts working, it can drive the shaft and roller to rotate, ensuring the normal printing work of the product. The shaft is rotatably mounted on the adjustment plate through the mounting bracket. This ensures that the shaft can be flexibly adjusted in height, and also ensures the normal rotation of the shaft and roller, ensuring the normal operation of the printing work and providing convenience for the user.

[0017] 5. This utility model, through the setting of an adjusting plate, a sliding sleeve, and a fixed bracket, uses an adjusting plate to install and fix a stepper motor, a mounting bracket, a sliding sleeve, and a threaded sleeve.

Four sliding sleeves are installed on one adjusting plate, and all four sliding sleeves are slidably installed on one side of the fixed bracket to limit the movement adjustment of the adjusting plate, ensuring that the adjusting plate moves straight up and down, and providing convenience for the user's adjustment work.

[0018] 6. This utility model, through the setting of a fixed bracket, threaded sleeve, adjusting screw, stepper motor, and synchronous wheel two, operates by starting the stepper motor to drive synchronous wheel two to rotate. Synchronous wheel two drives synchronous wheel one to rotate via a synchronous belt. Synchronous wheel one drives the shaft and roller components to rotate, thereby printing the product and ensuring the normal operation of the printing process. The processing height of the roller components can also be adjusted according to the different thicknesses of the printed product. During adjustment, the user rotates the adjusting screw. It should be noted that a hand crank is installed at the top of the adjusting screw, located on the outside of the worktable. When the adjusting screw rotates, it drives the threaded sleeve to move up and down. At the same time, the threaded sleeve drives the adjusting plate to move up and down. Multiple sliding sleeves installed on the adjusting plate also slide on the fixed bracket, which limits the movement of the adjusting plate. Simultaneously, the stepper motor, mounting bracket, and roller components installed on the adjusting plate also move up and down with the adjusting plate, thereby realizing the adjustment of the printing height of the roller components to meet the printing processing needs of products with different thicknesses and providing convenience for users.

[0019] 7.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] A metal wire drawing printing roller with easy replacement function includes two shafts 1 arranged adjacent to each other. An inner support 2 is sleeved on the surface of the shaft 1. An end block 3 is snapped onto one end of the inner support 2. Both ends of one side of the end block 3 are integrally formed with locking blocks 4. A groove 6 adapted to the end block 3 is opened at one end of the inner support 2. The groove 6 has slots 7 adapted to the locking blocks 4 on both sides of its inner cavity. A roller component 8 is sleeved on the surface of the inner support 2. Notches 9 adapted to the roller component 8 are opened at the top and bottom of the inner support 2.

[0031] The specific usage process is as follows: When replacing the printing roller, first loosen and remove the fastening bolt 5 from the shaft 1 and end block 3. Then rotate the end block 3 clockwise to drive the locking block 4 to slide in the slot 7 until the locking block 4 is aligned with the opening on the outside of the slot 7. At this point, the end block 3 can be removed outwards. Then, remove the roller 8 and the inner bracket 2 together from the shaft 1. This completes the disassembly of the roller 8. Then, replace it with a new roller 8 and install it on the shaft 1. During installation, first fit the inner bracket 2 onto the shaft 1. The stop block 11 is fixed on the shaft 1 and is used to restrict the axial movement of the inner bracket 2 and the roller 8. After the inner bracket 2 is fitted and installed, align the end of the inner bracket 2 facing the stop block 11 with the stop block 11. The side of the stop block 11 has a protrusion similar to that of the end block 3. The side of the stop block 11 then engages with the inner support 2. It should be noted that the outer surface of the stop block 11 and the inner surface of the inner support 2 will generate significant friction, preventing the inner support 2 from easily moving after engaging with the stop block 11. Before installing the inner support 2, the roller 8 must first be fitted onto the inner support 2, that is, fitted from the end of the inner support 2 facing the stop block 11. The two protruding parts of the inner wall of the roller 8 should align with the two notches 9. Then, the inner support 2 is inserted into the roller 8, and the protruding parts of the inner wall of the roller 8 will also engage with the corresponding notches 9, thus preventing the inner support 2 from moving freely. Under these conditions, the roller component 8 will not move freely. Then, install the end block 3 onto the inner support 2. The protruding part of the end block 3 should engage with the groove 6. Then, the locking block 4 should be aligned with the slot 7 and engaged. Then, rotate the end block 3 counterclockwise. In this way, the locking block 4 can also slide with the end block 3 in the slot 7. Finally, the locking block 4 will be locked deep inside the slot 7. At this time, the inner support 2 and the roller component 8 will not move freely, and the installed end block 3 will not move freely either. The screw hole on the end block 3 will also be aligned with the bolt hole 10. Finally, pass the fastening bolt 5 through the screw hole on the end block 3 and insert it into the corresponding bolt hole 10. Finally, tighten the fastening bolt 5 to fix the end block 3 onto the shaft 1. At the same time, the end block 3, together with the locking block 4 and the slot 7, is also fixed inside. The roller component 8, mounted on bracket 2, is also fixed to the inner bracket 2. Therefore, after the fastening bolts 5 are installed, the entire roller component 8 is assembled and can be quickly put into use. During installation, the roller component 8 will not move freely. Under the direct or indirect limiting action of the stop block 11, the inner bracket 2, and the end block 3, the roller component 8 and the inner bracket 2 can be positioned in their original positions, allowing for the quick insertion of the fastening bolts 5. This quickly completes the assembly of the roller component 8, providing convenience for the user's assembly work, improving the assembly efficiency of the roller component 8, and facilitating user operation. After the roller component 8 is replaced, the machine can be started. During operation, the stepper motor 19 is activated, driving the synchronous pulley 20 to rotate.Synchronous pulley 20 drives synchronous pulley 12 via a synchronous belt. Synchronous pulley 12 drives shaft 1 to rotate on two mounting brackets 13. Finally, the roller 8 mounted on shaft 1 also rotates with shaft 1, thus printing the products placed on conveyor belt 22. The products are placed on conveyor belt 22 from the outside of shaft 1, undergo printing as they pass through roller 8, and are then conveyed out of shaft 1 by conveyor belt 22, completing the printing process. Bolt holes 10 are used to insert fastening bolts 5. During installation, fastening bolts 5 are inserted from the outside of end block 3 until they are inserted into the corresponding bolt holes 10, and then tightened to fix them in the bolt holes 10. This allows for the replacement of roller 8. The first step is fixed to ensure the stability of the printing operation of the roller component 8 and provide convenience for the user. The stop block 11 is used to block and limit the inner support 2 and the roller component 8, ensuring that the roller component 8 and the inner support 2 can be accurately installed in the set position, providing convenience for the user. The first synchronous pulley 12 is used to drive the second synchronous pulley 20. The first synchronous pulley 12 and the second synchronous pulley 20 are driven by a synchronous belt. In this way, when the stepper motor 19 starts working, it can drive the shaft 1 and the roller component 8 to rotate, ensuring the normal printing operation of the product. The shaft 1 is rotatably mounted on the adjusting plate 14 through the mounting bracket 13. In this way, while ensuring that the height of the shaft 1 can be flexibly adjusted, the normal rotation of the shaft 1 and the roller component 8 can also be ensured. The adjustment plate 14 is used to mount and fix the stepper motor 19, mounting bracket 13, sliding sleeve 15, and threaded sleeve 17. This allows the stepper motor 19, mounting bracket 13, sliding sleeve 15, and threaded sleeve 17 to move up and down with the adjustment plate 14, thereby adjusting the height of the roller component 8 as well. Four sliding sleeves 15 are mounted on one adjustment plate 14, all slidingly mounted on one side of the fixed bracket 16. These sleeves limit the movement of the adjustment plate 14, ensuring its straight up and down movement and providing convenience for the user's adjustment work. During operation, the stepper motor 19 is started, driving the synchronous pulley 20. During operation, synchronous pulley 20 drives synchronous pulley 12 to rotate via a synchronous belt. Synchronous pulley 12 then drives shaft 1 and roller 8 to rotate, thereby printing the product and ensuring the normal operation of the printing process. The processing height of roller 8 can be adjusted according to the different thicknesses of the printed product. During adjustment, the user rotates the adjusting screw 18. It should be noted that a hand crank is installed at the top of the adjusting screw 18, located on the outside of the worktable 21. When the adjusting screw 18 rotates, it drives the threaded sleeve 17 to move up and down. At the same time, the threaded sleeve 17 drives the adjusting plate 14 to move up and down. Multiple sliding sleeves 15 installed on the adjusting plate 14 also slide on the fixed bracket 16, which limits the movement of the adjusting plate 14.Simultaneously, the stepper motor 19 mounted on the adjusting plate 14, along with the mounting bracket 13 and the roller assembly 8, will move up and down together with the adjusting plate 14, thereby adjusting the printing height of the roller assembly 8 to meet the printing processing needs of products of different thicknesses and provide convenience for users. The two ends of the conveyor belt 22 are used for feeding and discharging materials respectively. Users put the product in from the feeding end, process it through the roller assembly 8, and then send it out from the discharging end, thus providing convenience for users.

[0032] Therefore, a snap-fit ​​structural design is adopted, in which the printing roller is connected and fixed to the shaft in a snap-fit ​​manner. This allows for quick connection of the printing roller and the shaft, preventing the printing roller from moving freely on the shaft during subsequent bolt installation. The printing roller and the shaft can be quickly installed together with bolts, ensuring that the printing roller can be put into use quickly and providing convenience for users.

[0033] One end of the shaft 1 is provided with multiple bolt holes 10, and multiple fastening bolts 5 that are adapted to the bolt holes 10 are provided through the outer side of the end block 3.

[0034] Specifically, the bolt hole 10 and the fastening bolt 5 are designed so that the bolt hole 10 is used to insert and install the fastening bolt 5. During installation, the fastening bolt 5 is inserted from the outside of the end block 3 until it is inserted into the corresponding bolt hole 10. Then, the fastening bolt 5 is tightened to fix it in the bolt hole 10. This can further fix the replaced roller 8, ensure the stability of the printing operation of the roller 8, and provide convenience for the user's work.

[0035] A stop 11 is fixedly installed on the surface of the shaft 1, and the stop 11 is adapted to the inner support 2 and the roller component 8.

[0036] Specifically, the stop block 11 is used to block and limit the inner support 2 and the roller component 8, ensuring that the roller component 8 and the inner support 2 can be accurately installed in the set position, providing convenience for the user's work.

[0037] One end of the stop block 11 is fixedly installed with a timing wheel 12, and the surface of the shaft 1 is fitted with a plurality of mounting brackets 13 located between the stop block 11 and the timing wheel 12.

[0038] Specifically, the synchronous pulley 12 and the mounting bracket 13 are configured such that synchronous pulley 12 is used to drive synchronous pulley 20. Synchronous pulley 12 and synchronous pulley 20 are driven by a synchronous belt. When the stepper motor 19 starts working, it can drive the shaft 1 and the roller 8 to rotate, ensuring the normal printing of the product. The shaft 1 is rotatably mounted on the adjusting plate 14 through the mounting bracket 13. This ensures that the height of the shaft 1 can be flexibly adjusted, and also ensures the normal rotation of the shaft 1 and the roller 8, ensuring the normal operation of the printing work and providing convenience for the user.

[0039] A fixed bracket 16 is provided between the two shafts 1. An adjusting plate 14 is provided on both sides of the fixed bracket 16. Four sliding sleeves 15 are fixedly connected to one side of the adjusting plate 14. The four sliding sleeves 15 are slidably installed on one side of the fixed bracket 16.

In this way, the stepper motor 19, mounting bracket 13, sliding sleeve 15, and threaded sleeve 17 can move up and down together with the adjustment plate 14, and the roller component 8 can also move and adjust its height together with the adjustment plate 14. Four sliding sleeves 15 are installed on one adjustment plate 14, and all four sliding sleeves 15 are slidably installed on one side of the fixed bracket 16 to limit the movement adjustment of the adjustment plate 14, ensuring that the adjustment plate 14 moves straight up and down, providing convenience for the user's adjustment work.

[0041] Adjusting screws 18 are provided through both sides of the top of the fixed bracket 16. A threaded sleeve 17 located inside the fixed bracket 16 is threaded on the surface of the adjusting screw 18. One side of the threaded sleeve 17 is fixedly installed on the adjusting plate 14. A stepper motor 19 is fixedly installed on the outer side of the adjusting plate 14. A second synchronous pulley 20 is fixedly installed on the output shaft of the stepper motor 19.

[0042] Specifically, the setup includes a fixed bracket 16, threaded sleeve 17, adjusting screw 18, stepper motor 19, and synchronous pulley 20. During operation, the stepper motor 19 drives synchronous pulley 20 to rotate. Synchronous pulley 20, via a synchronous belt, drives synchronous pulley 12 to rotate. Synchronous pulley 12 then drives shaft 1 and roller 8 to rotate, thus performing printing processing on the product and ensuring the normal operation of the printing process. The processing height of roller 8 can also be adjusted according to the different thicknesses of the printed product. Adjustment is achieved by rotating the adjusting screw 18. It should be noted that a hand crank is installed at the top of the adjusting screw 18. The hand crank is located on the outside of the worktable 21. When the adjusting screw 18 is rotated, it drives the threaded sleeve 17 to move up and down. At the same time, the threaded sleeve 17 drives the adjusting plate 14 to move up and down. Multiple sliding sleeves 15 installed on the adjusting plate 14 also slide on the fixed bracket 16, which limits the movement of the adjusting plate 14. Meanwhile, the stepper motor 19 installed on the adjusting plate 14, as well as the mounting bracket 13 and the roller component 8, also move up and down with the adjusting plate 14, thereby realizing the adjustment of the printing height of the roller component 8, meeting the printing processing of products with different thicknesses, and providing convenience for users' work.
