Description

Technical Field

[0001] This invention relates to the field of printing registration technology, and in particular to a printing registration accuracy control device. Background Technology

[0002] Printing registration accuracy refers to the accuracy of the alignment of each monochrome plate pattern on the substrate in multicolor printing, and it is one of the important indicators for measuring printing quality.

[0003] A related technology, Chinese Patent No. CN221913651U, discloses a printing press cylinder registration calibration and adjustment mechanism. This mechanism includes a base, two sets of support plates fixedly mounted on the top of the base, a horizontal adjustment mechanism slidably mounted on the side walls of the support plates, a cylinder body rotatably mounted inside the horizontal adjustment mechanism, and the horizontal adjustment mechanism drives the cylinder body to move horizontally. A vertical adjustment mechanism is fixedly mounted at the bottom of the horizontal adjustment mechanism, and the vertical adjustment mechanism drives the horizontal adjustment mechanism to move vertically. When the horizontal position of the cylinder body needs adjustment, the horizontal adjustment mechanism drives the cylinder body to move horizontally; when the vertical position of the cylinder body needs adjustment, the vertical adjustment mechanism drives the cylinder body to move vertically.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: Since the position of the roller body is not easily adjusted along its axial direction, multiple roller bodies are prone to misalignment along the width direction of the substrate during multicolor printing, resulting in a decrease in printing registration accuracy. Summary of the Invention

[0005] To reduce the decrease in printing registration accuracy, this application provides a printing registration accuracy control device.

[0006] The printing registration accuracy control device provided in this application adopts the following technical solution: A printing registration accuracy control device includes a mounting base, a set of support plates on the mounting base, a roller body rotatably mounted between the support plates, a driving assembly between the roller body and one of the support plates for driving the roller body to rotate, a support seat shared on the support plates, a radial assembly between the support seat and the mounting base for adjusting the position of the roller body along the radial direction, and an axial assembly between the radial assembly and the mounting base for adjusting the position of the roller body along the axial direction.

[0007] By adopting the above technical solution, in the multi-color printing process, the radial component is used to adjust the position of the roller body along the radial direction of the roller body, and the axial component is used to adjust the position of the roller body along the axial direction of the roller body. This achieves the effect of facilitating the adjustment of the position of the roller body, reducing the misalignment of multiple roller bodies. After the roller body is adjusted to the appropriate position, the drive component is used to rotate the roller body to achieve the printing effect on the substrate, reducing the decrease in printing registration accuracy.

[0008] Preferably, the radial assembly includes a radial rotating shaft and several radial piston cylinders. The output shaft of each radial piston cylinder is connected to the side of the support base away from the support plate. A connecting sleeve is provided on each radial piston cylinder. Each connecting sleeve is fitted onto the radial rotating shaft. The radial rotating shaft is rotatably mounted on the mounting base. The connecting sleeve is slidably connected to the radial rotating shaft. Several connecting blocks are fixedly provided on the inner wall of the connecting sleeve. Several connecting grooves are opened on the outer wall of the radial rotating shaft. The connecting blocks are slidably mounted in the connecting grooves. The sidewalls of the connecting blocks are in contact with the inner wall of the connecting grooves.

[0009] By adopting the above technical solution, when the position of the drum body is adjusted along the radial direction of the drum body, the rotation of the radial shaft drives the connecting sleeve to rotate synchronously. The rotation of the connecting sleeve drives the support seat on the radial piston cylinder to rotate around the radial shaft as the axis. At the same time, the output shaft of the radial piston cylinder extends and retracts to adjust the distance between the support seat and the radial shaft, thereby achieving the effect of adjusting the position of the drum body along the radial direction of the drum body.

[0010] Preferably, the radial assembly further includes a radial motor, a radial slider, a radial screw, a radial rack, and a radial gear. A radial groove is formed on the mounting base. The radial motor is fixedly disposed within the radial groove. The output shaft of the radial motor is fixedly connected to the radial screw. The radial screw is rotatably connected to the inner wall of the radial groove. The radial slider is slidably disposed within the radial groove. The radial slider is threadedly connected to the radial screw. The radial slider is fixedly connected to the radial rack. The radial gear is sleeved on a radial rotating shaft and fixedly connected to the radial rotating shaft. The radial gear and the radial rack mesh with each other.

[0011] By adopting the above technical solution, the radial motor starts and drives the radial screw to rotate. The rotation of the radial screw causes the radial slider to move along the radial groove. The movement of the radial slider causes the radial gear to move. The movement of the radial gear causes the radial gear to rotate. The rotation of the radial gear causes the radial shaft to rotate.

[0012] Preferably, the axial assembly includes a left piston cylinder, a left ring plate, a right piston cylinder, and a right ring plate. The left and right piston cylinders are both fixedly mounted on the mounting base. The output shafts of the left and right piston cylinders are opposite to each other. The output shaft of the left piston cylinder is connected to the left ring plate, and the output shaft of the right piston cylinder is connected to the right ring plate. The left and right ring plates are both sleeved on a radial rotating shaft. The connecting sleeves are located between the left and right ring plates, and the opposing surfaces of the left and right ring plates are used to abut against the connecting sleeves.

[0013] By adopting the above technical solution, when the output shaft of the left piston cylinder extends, the output shaft of the right piston cylinder shortens, causing the connecting sleeve between the left and right ring plates to move synchronously closer to the right piston cylinder. When the output shaft of the right piston cylinder extends, the output shaft of the left piston cylinder shortens, causing the connecting sleeve between the left and right ring plates to move synchronously closer to the left piston cylinder. During the movement of the connecting sleeve, the connecting sleeve drives the radial piston cylinder to move, and the movement of the radial piston cylinder drives the roller body on the support to move, thereby achieving the effect of adjusting the position of the roller body along the axial direction of the roller body.

[0014] Preferably, a support spindle is provided through the support plate, the support spindle is rotatably connected to the support plate, a number of support blocks are fixedly provided on the side wall of the support spindle, and a support slot and a number of support grooves are provided on the end wall of the roller body. The support slot and the support grooves are interconnected. The support slot is for the support spindle to be inserted, and the support groove is for the support blocks to be inserted. One of the support spindles is connected to the drive assembly.

[0015] By adopting the above technical solution, the roller body and the support plate are connected together by the support spindle and the support block. When the support spindle rotates, the support spindle drives the support block to rotate, and the support block inserted in the support slot drives the roller body to rotate synchronously.

[0016] Preferably, the support base has an adjustment groove on the side facing the support plate. A set of adjustment blocks are slidably arranged in the adjustment groove. An adjustment motor is fixedly arranged in the adjustment groove. A forward lead screw is fixedly arranged on the output shaft of the adjustment motor. A reverse lead screw is fixedly arranged on the forward lead screw. The reverse lead screw is rotatably connected to the inner wall of the support groove. The forward lead screw is threadedly connected to one of the adjustment blocks. The reverse lead screw is threadedly connected to the other adjustment block. One of the adjustment blocks is fixedly connected to one of the support plates. The other adjustment block is fixedly connected to the support plate. The opposite surface of the support plate is used to abut against the end wall of the roller body.

[0017] By adopting the above technical solution, the motor drive drives the forward and reverse lead screws to rotate synchronously. The synchronous rotation of the forward and reverse lead screws causes the adjusting block to move along the adjusting groove. The movement of the adjusting block drives the support plate to move, adjusting the distance between the support plates, which facilitates the replacement of the roller body between the support plates.

[0018] Preferably, an abutment ring is rotatably disposed on the opposite surface of the support plate. The abutment ring is sleeved on the support spindle and the support block, and the opposite surface of the abutment ring is used to abut against the end wall of the roller body.

[0019] By adopting the above technical solution, when the roller body is installed between the support plates, the abutment ring abuts against the end wall of the roller body. When the roller body rotates, the abutment ring rotates under the friction of the roller body, thereby reducing the friction between the roller body and the support plate.

[0020] Preferably, the drive assembly includes a drive motor, a drive gear, and a transmission gear. The drive motor is fixedly connected to one of the support plates, the output shaft of the drive motor is fixedly connected to the drive gear, the transmission gear is fixedly connected to one of the support main shafts, and the transmission gear meshes with the drive gear.

[0021] By adopting the above technical solution, the drive motor starts and drives the drive gear to rotate, the drive gear rotates and drives the transmission gear to rotate, the transmission gear rotates and drives the support shaft to rotate, and the support shaft rotates and drives the drum body to rotate synchronously.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a mounting base, support plate, roller body, drive assembly, support seat, radial assembly, and axial assembly, in the multi-color printing process, the radial assembly is used to adjust the position of the roller body along the radial direction of the roller body, and the axial assembly is used to adjust the position of the roller body along the axial direction of the roller body. This achieves the effect of easy adjustment of the position of the roller body, reduces the misalignment of multiple roller bodies, and when the roller body is adjusted to the appropriate position, the drive assembly is used to rotate the roller body to achieve the printing effect on the substrate and reduce the decrease in printing registration accuracy. 2. By setting a radial rotating shaft, a radial piston cylinder, a connecting sleeve, a connecting block, and a connecting slide, the position of the roller body can be adjusted along the radial direction of the roller body; 3. By setting up a left piston cylinder, a left ring plate, a right piston cylinder, and a right ring plate, the position of the drum body can be adjusted along the axial direction of the drum body.

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses a printing registration accuracy control device. (Refer to...) Figure 1 The system includes a support base 2, on which a set of support plates 3 are slidably mounted, and a roller body 4 is detachably mounted between the support plates 3. A drive assembly 8 is installed between the roller body 4 and one of the support plates 3, and the drive assembly 8 is used to drive the roller body 4 to rotate. A mounting seat 1 is provided on the side of the support base 2 away from the support plates 3, and a radial assembly 5 is installed between the support base 2 and the mounting seat 1. The radial assembly 5 is used to adjust the position of the roller body 4 in the radial direction. An axial assembly 7 is installed between the radial assembly 5 and the mounting seat 1, and the axial assembly 7 is used to adjust the position of the roller body 4 in the axial direction. In the multi-color printing process, the radial assembly 5 is used to adjust the position of the roller body 4 in the radial direction, and the axial assembly 7 is used to adjust the position of the roller body 4 in the axial direction, so as to facilitate the adjustment of the position of the roller body 4 and reduce the misalignment of multiple roller bodies 4. After the roller body 4 is adjusted to the appropriate position, the drive assembly 8 is used to rotate the roller body 4 to achieve the printing effect on the substrate and reduce the decrease in printing registration accuracy.

[0032] Reference Figure 1 and Figure 2 An adjustment groove 21 is formed on the side of the support base 2 facing the support plate 3. A set of adjustment blocks 22 are slidably arranged in the adjustment groove 21. One adjustment block 22 is welded to one of the support plates 3, and the other adjustment block 22 is welded to the support plate 3. An adjustment motor 23 is installed in the adjustment groove 21. A forward lead screw 24 is installed on the output shaft of the adjustment motor 23, and a reverse lead screw 25 is installed on the forward lead screw 24. The reverse lead screw 25 is rotatably connected to the inner wall of the support groove. The forward lead screw 24 is threaded to one of the adjustment blocks 22, and the reverse lead screw 25 is threaded to the other adjustment block 22. The adjustment motor 23 drives the forward lead screw 24 and the reverse lead screw 25 to rotate synchronously. The synchronous rotation of the forward lead screw 24 and the reverse lead screw 25 causes the adjustment blocks 22 to move along the adjustment groove 21. The movement of the adjustment blocks 22 causes the support plates 3 to move, adjusting the distance between the support plates 3, which facilitates the replacement of the roller body 4 between the support plates 3.

[0033] Reference Figure 1 and Figure 2 A support spindle 31 is mounted through the support plate 3, and the support spindle 31 is rotatably connected to the support plate 3. One of the support spindles 31 is connected to the drive assembly 8, and several support blocks 32 are installed on the side wall of the support spindle 31. The end wall of the roller body 4 has a support slot 41 and several support grooves 42, which are interconnected. The support slot 41 is for inserting the support spindle 31, and the support grooves 42 are for inserting the support blocks 32. The roller body 4 and the support plate 3 are engaged together by the support spindle 31 and the support blocks 32. An abutment ring 9 is rotatably mounted on the opposite surface of the support plate 3. The abutment ring 9 is sleeved on the support spindle 31 and the support blocks 32, and the opposite surface of the abutment ring 9 is used to abut against the end wall of the roller body 4. When the roller body 4 is installed between the support plates 3, the abutment ring 9 abuts against the end wall of the roller body 4. When the support spindle 31 rotates, it drives the support block 32 to rotate, and the support block 32, which is inserted into the support slot 42, drives the roller body 4 to rotate synchronously. When the roller body 4 rotates, the abutment ring 9 rotates under the friction of the roller body 4, reducing the friction between the roller body 4 and the support plate 3.

[0034] Reference Figure 1 and Figure 2The drive assembly 8 includes a drive motor 81, a drive gear 82, and a transmission gear 83. The drive motor 81 is mounted on one of the support plates 3, and the output shaft of the drive motor 81 is welded to the drive gear 82. The transmission gear 83 is welded to one of the support shafts 31, and the transmission gear 83 meshes with the drive gear 82. When the drive motor 81 starts, it drives the drive gear 82 to rotate. The rotation of the drive gear 82 drives the transmission gear 83 to rotate. The rotation of the transmission gear 83 drives the support shaft 31 to rotate, and the rotation of the support shaft 31 drives the roller body 4 to rotate synchronously.

[0035] Reference Figures 1 to 6 The radial assembly 5 includes a radial shaft 51, several radial piston cylinders 52, a radial motor 53, a radial slider 54, a radial screw 55, a radial rack 56, and a radial gear 57. A radial groove 58 is formed on the side of the mounting base 1 facing the support base 2, and the radial motor 53 is installed in the radial groove 58. The output shaft of the radial motor 53 is welded to one end of the radial screw 55, and the other end of the radial screw 55 is rotatably connected to the inner wall of the radial groove 58. The radial slider 54 is slidably disposed in the radial groove 58, and the radial slider 54 is threadedly connected to the radial screw 55. The radial shaft 51 is rotatably disposed on the mounting base 1, and the radial gear 57 is sleeved on the radial shaft 51 and welded to the radial shaft 51. The radial rack 56 is mounted on the radial slider 54, and the radial gear 57 meshes with the radial rack 56. The output shaft of the radial piston cylinder 52 is connected to the side of the support base 2 away from the support plate 3. A connecting sleeve 6 is installed on the radial piston cylinder 52, and the connecting sleeve 6 is fitted onto the radial rotating shaft 51, with the connecting sleeve 6 and the radial rotating shaft 51 slidably connected. Several connecting blocks 61 are fixedly provided on the inner wall of the connecting sleeve 6, and several connecting grooves 62 are opened on the outer wall of the radial rotating shaft 51. The connecting blocks 61 are slidably disposed in the connecting grooves 62, and the side walls of the connecting blocks 61 are in contact with the inner walls of the connecting grooves 62. When the position of the roller body 4 is adjusted along the radial direction of the roller body 4, the radial motor 53 starts and drives the radial screw 55 to rotate. The rotation of the radial screw 55 drives the radial slider 54 to move along the radial groove 58. The movement of the radial slider 54 drives the radial gear 57 to move. The movement of the radial gear 57 drives the radial gear 57 to rotate, and the rotation of the radial gear 57 drives the radial rotating shaft 51 to rotate. The rotation of the radial shaft 51 drives the connecting sleeve 6 to rotate synchronously. The rotation of the connecting sleeve 6 drives the support seat 2 on the radial piston cylinder 52 to rotate around the radial shaft 51 as the axis. At the same time, the output shaft of the radial piston cylinder 52 extends and retracts to adjust the distance between the support seat 2 and the radial shaft 51, thereby achieving the effect of adjusting the position of the roller body 4 in the radial direction of the roller body 4.

[0036] Reference Figures 1 to 3The axial assembly 7 includes a left piston cylinder 71, a left ring plate 711, a right piston cylinder 72, and a right ring plate 721. Both the left piston cylinder 71 and the right piston cylinder 72 are mounted on the mounting base 1, with the output shafts of the left piston cylinder 71 and right piston cylinder 72 positioned opposite each other. The output shaft of the left piston cylinder 71 is connected to the left ring plate 711, and the output shaft of the right piston cylinder 72 is connected to the right ring plate 721. Both the left ring plate 711 and the right ring plate 721 are sleeved on the radial rotating shaft 51. Connecting sleeves 6 are located between the left ring plate 711 and the right ring plate 721, with the opposing surfaces of the left ring plate 711 and the right ring plate 721 abutting against the connecting sleeves 6. When the output shaft of the left piston cylinder 71 extends, the output shaft of the right piston cylinder 72 shortens, causing the connecting sleeve 6, which abuts between the left ring plate 711 and the right ring plate 721, to move synchronously towards the right piston cylinder 72. Conversely, when the output shaft of the right piston cylinder 72 extends, the output shaft of the left piston cylinder 71 shortens, causing the connecting sleeve 6, which abuts between the left ring plate 711 and the right ring plate 721, to move synchronously towards the left piston cylinder 71. During the movement of the connecting sleeve 6, the connecting sleeve 6 drives the radial piston cylinder 52 to move, which in turn drives the roller body 4 on the support base 2 to move, thereby achieving the effect of adjusting the position of the roller body 4 along its axial direction.

[0037] The implementation principle of the printing registration accuracy control device in this application embodiment is as follows: The radial motor 53 starts and drives the radial screw 55 to rotate. The rotation of the radial screw 55 drives the radial slider 54 to move along the radial groove 58. The movement of the radial slider 54 drives the radial gear 57 to move. The movement of the radial gear 57 drives the radial gear 57 to rotate. The rotation of the radial gear 57 drives the radial shaft 51 to rotate. The rotation of the radial shaft 51 drives the connecting sleeve 6 to rotate synchronously. The rotation of the connecting sleeve 6 drives the support seat 2 on the radial piston cylinder 52 to rotate around the radial shaft 51. At the same time, the output shaft of the radial piston cylinder 52 extends and retracts to adjust the distance between the support seat 2 and the radial shaft 51, thereby achieving the effect of adjusting the position of the roller body 4 in the radial direction. When the output shaft of the left piston cylinder 71 extends, the output shaft of the right piston cylinder 72 shortens, causing the connecting sleeve 6, which abuts between the left ring plate 711 and the right ring plate 721, to move synchronously towards the right piston cylinder 72. Conversely, when the output shaft of the right piston cylinder 72 extends, the output shaft of the left piston cylinder 71 shortens, causing the connecting sleeve 6, which abuts between the left ring plate 711 and the right ring plate 721, to move synchronously towards the left piston cylinder 71. During the movement of the connecting sleeve 6, the connecting sleeve 6 drives the radial piston cylinder 52 to move, which in turn drives the roller body 4 on the support base 2 to move, thus achieving the effect of adjusting the position of the roller body 4 along its axial direction. Once the roller body 4 is adjusted to the appropriate position, the drive motor 81 starts, driving the drive gear 82 to rotate. The drive gear 82 then drives the transmission gear 83 to rotate, which in turn drives the support shaft 31 to rotate. The rotation of the support shaft 31 then drives the roller body 4 to rotate synchronously, achieving the effect of printing on the substrate. This facilitates the adjustment of the roller body 4's position, reduces the possibility of misalignment among multiple roller bodies 4, and minimizes the decrease in printing registration accuracy.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
