Description

Technical Field

[0001] This utility model relates to the field of gravure roller transfer technology, and in particular to a transfer station for a central printing roller. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Its working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images. This ink is then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thus reproducing a printed product identical to the printing plate. The invention and development of the printing press has played a vital role in the dissemination of human civilization and culture.

[0003] The support base is mostly a fixed structure, and the posture cannot be adjusted during the temporary storage or transfer of the printing roller. Subsequent processes require manual assistance to flip and align it, which is not only inefficient, but also prone to scratches on the surface of the printing roller or bumps on the shaft head due to manual operation. Utility Model Content

[0004] The purpose of this invention is to provide a transfer station for centering printing rollers, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: The intermediate station for centering the printing roller includes a bottom support module and a top support module that moves along the length of the bottom support module. The top support module includes a transfer moving seat that slides with the bottom support module. The transfer moving seat is equipped with a rotating support seat that can rotate laterally. The top of the rotating support seat has a temporary storage station. The temporary storage station includes printing roller support seats that are spaced apart and provide rolling support for the printing roller. A pair of guide sleeves are installed at an angle on the printing roller support seats. The two guide sleeves are symmetrically arranged to provide rolling support for the printing roller. Buffer modules that position the ends of the printing roller are respectively provided on both sides of the printing roller support seats. The buffer modules can move along the length of the printing roller.

[0006] Furthermore: the rotating support base is formed with a V-shaped guide groove, and the left and right walls of the guide groove are both formed with inclined guide slopes, and the guide sleeve is installed on the guide slopes.

[0007] Furthermore: a rotating shaft is installed inside the guide sleeve, and mounting grooves for installing the rotating shaft are formed at both ends of the guide slope, with buffer springs arranged perpendicular to the rotating shaft in the mounting grooves.

[0008] Furthermore: the bottom support module includes a bottom support plate, a pair of parallel and spaced bottom guide rails arranged along the length of the bottom support plate, and a bottom sliding seat that slides with the bottom guide rails installed at the bottom of the transfer moving seat; a parallel bottom drive rack is installed on the side of one of the bottom guide rails, and a bottom drive gear that meshes with the bottom drive rack and a bottom drive motor that drives the bottom drive gear to rotate are installed on the transfer moving seat.

[0009] Furthermore: the transfer moving seat is equipped with a top drive mechanism for supporting the buffer module. The top drive mechanism includes a transverse drive seat arranged perpendicular to the transfer moving seat. The transverse drive seat has a top guide post arranged along its length. The buffer modules are slidably installed on the top guide posts. The buffer module includes a buffer support seat. A top guide sleeve that slides with the top guide post is installed at the bottom of the buffer support seat.

[0010] Furthermore: a side mounting plate is installed on the top of the buffer support seat, and a buffer pad is installed on the side mounting plate and aligned with the printing roller. The two buffer supports simultaneously move away from or close to each other to elastically clamp printing rollers of different lengths.

[0011] Furthermore, the top drive mechanism also includes a top drive rack arranged parallel to the top guide post. The top drive rack is connected to the buffer support seat. The lateral drive seat is equipped with a top drive gear that is located between the two top drive racks and simultaneously meshes with the two top drive racks. The lateral drive seat is also equipped with a lateral telescopic drive component, the drive end of which is connected to one of the buffer supports.

[0012] Furthermore, the number of temporary storage stations is two or more.

[0013] Furthermore: A rotary motor is installed on the top of the transfer station, and a rotating disk is installed on the drive end of the rotary motor. The rotating disk is installed at the bottom of the rotating support base.

[0014] Furthermore, the top of the transfer station is also equipped with a rolling support structure that provides rolling support for the rotating disk. The beneficial effects of this utility model are as follows: Printing rollers requiring transfer are positioned via a temporary storage station. During positioning, two symmetrically arranged guide sleeves form a V-shaped support, utilizing the roller's own weight for automatic centering, significantly improving positioning accuracy. The guide sleeves convert sliding friction into rolling friction, reducing the friction coefficient and minimizing wear on the roller surface, protecting the printed image area. Subsequently, the buffer module can move along the length of the roller, clamping both ends for installation and positioning, preventing the roller from shifting due to inertia during the temporary storage station's movement, ensuring positioning stability. After positioning, the rotating support at the top of the transfer station can rotatably change the roller's direction, or move along the length of the bottom support module, seamlessly connecting with different automated production lines. This enables fully automated transfer of printing rollers from storage to printing, reducing manual intervention and labor intensity. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, the transfer station for centering the printing roller includes a bottom support module 1 and a top support module that moves along the length of the bottom support module 1. The top support module includes a transfer moving seat 2 that slides with the bottom support module 1. The transfer moving seat 2 is equipped with a rotating support seat 27 that can rotate laterally. The top of the rotating support seat 27 has a temporary storage station 3. The temporary storage station 3 includes printing roller support seats 31 arranged at intervals to support the rolling of the printing roller. A pair of guide sleeves 32 are installed obliquely on the printing roller support seats 31. The two guide sleeves 32 are symmetrically arranged to support the rolling of the printing roller. Buffer modules 40 for positioning the ends of the printing roller are respectively provided on both sides of the printing roller support seats 31. The buffer modules 40 can move along the length of the printing roller.

[0023] The printing rollers that need to be transferred are positioned at the temporary storage station 3. During positioning, two symmetrically arranged guide sleeves 32 form a V-shaped support, and the rollers automatically center themselves using their own weight, greatly improving positioning accuracy. The guide sleeves 32 convert sliding friction into rolling friction, reducing the coefficient of friction and minimizing wear on the roller surface, thus protecting the printed image area. Subsequently, the buffer module 40 can move along the length of the roller to clamp both ends, achieving installation and positioning. This prevents the rollers from moving due to inertia during the movement of the temporary storage station 3, ensuring positioning stability. After positioning, the rotating support seat 27 at the top of the transfer moving seat 2 can rotate to change the direction of the rollers, and can also move along the length of the bottom support module 1, seamlessly connecting with different automated production lines to achieve fully automated transfer of the printing rollers from storage to printing, reducing manual intervention and labor intensity.

[0024] Specifically, the rotating support base 27 has a V-shaped guide groove 33, and both the left and right sides of the guide groove 33 have inclined guide slopes 34. The guide sleeve 32 is installed on the guide slopes 34. The V-shaped guide groove 33 forms a centering guide channel, which, together with the inclined guide slopes 34 on both sides, allows the printing roller to automatically slide along the slopes to the center of the groove bottom when placed. This can accommodate printing rollers of different diameters without the need to replace support components, further enhancing the equipment's versatility.

[0025] Furthermore, a rotating shaft 35 is installed inside the guide sleeve 32, and mounting grooves 36 for mounting the rotating shaft 35 are formed at both ends of the guide slope 34. A buffer spring is arranged perpendicular to the rotating shaft 35 in the mounting groove 36. The buffer spring is arranged perpendicular to the rotating shaft 35, and the impact force acts directly on the spring axis; it can quickly absorb the axial impact force during the loading and unloading of the printing roller. The elastic tension of the spring continuously applies a constraint force to the center of the V-shaped guide slot 33, helping the printing roller maintain its alignment, while also absorbing slight vibrations in the production environment, reducing the impact of vibration on the positioning accuracy of the printing roller.

[0026] The bottom support module 1 includes a bottom support plate 11, with a pair of parallel and spaced bottom guide rails 12 arranged along the length of the bottom support plate 11. The bottom of the transfer moving seat 2 is equipped with a bottom sliding seat 13 that slides with the bottom guide rails 12. A parallel bottom drive rack 14 is installed on the side of one of the bottom guide rails 12. The transfer moving seat 2 is equipped with a bottom drive gear 15 that meshes with the bottom drive rack 14 and a bottom drive motor 16 that drives the bottom drive gear 15 to rotate.

[0027] In this embodiment, driven by the bottom drive motor 16, the bottom drive gear 15 rotates synchronously. The bottom drive gear 15 meshes with the bottom drive rack 14 to achieve transmission. At this time, the bottom sliding seat 13 at the bottom of the transfer moving seat 2 can move along the length direction of the bottom guide rail 12 to transfer the temporary storage station 3 on which the printing roller is installed. It can be moved according to the position of the production line, and the required length can be moved to facilitate the printing roller to cooperate with the production line at different positions and achieve high-efficiency transfer. In addition, the bottom drive motor 16 supports PLC signal control and can be linked with the central control system of the automated production line to realize automatic calculation and automatic adjustment of the support spacing without manual intervention, and is fully integrated into the fully automatic printing roller transfer system.

[0028] Furthermore, a rotary motor 21 is installed on the top of the transfer station 2, and a rotating disk 22 is installed on the drive end of the rotary motor 21. The rotating disk 22 is installed at the bottom of the rotating support base 27. The rotary motor 21 directly drives the rotating disk 22, eliminating the backlash error of indirect transmission such as belts and gears, resulting in high transmission efficiency. The rotary motor 21 is compatible with PLC and industrial bus control, and can be linked with the bottom drive motor 16 and upstream and downstream process equipment to achieve fully automated control of the entire process, including support spacing adjustment, roller alignment, and angle rotation, thus fully integrating into the intelligent production line.

[0029] In addition, the top of the transfer station 2 is also equipped with a rolling support structure 23 for rolling support of the rotating disk 22. The rolling support structure 23 includes a support frame 24 located around the rotary motor 21. The top of the support frame 24 is equipped with an annular plate 25 that is coaxially aligned with the rotating disk 22. The top of the annular plate 25 is equipped with a rolling bearing assembly 26. When the rotating disk 22 rotates, it is supported by the rolling bearing assembly 26, which can reduce friction, increase load-bearing capacity, reduce the load on the rotary motor 21, reduce energy consumption, and extend the service life of the rotary motor 21.

[0030] Specifically, the transfer moving seat 2 is equipped with a top drive mechanism 4 for supporting the buffer module 40. The top drive mechanism 4 includes a transverse drive seat 41 arranged perpendicular to the transfer moving seat 2. The transverse drive seat 41 is connected to the rotating support seat 27 and is arranged parallel to the printing roller. A top guide post 42 is arranged along the length of the transverse drive seat 41. The buffer module 40 is slidably installed on the top guide post 42. The buffer module 40 includes a buffer support seat 43. A top guide sleeve 44 is installed at the bottom of the buffer support seat 43 and slides with the top guide post 42. When the buffer support seat 43 moves, the top guide sleeve 44 slides with the top guide post 42 to achieve precise movement of the buffer module 40, ensuring that the buffer module 40 is always precisely aligned with the end of the printing roller, thereby facilitating the clamping and positioning of both ends of the printing roller.

[0031] Furthermore, a side mounting plate 45 is installed on the top of the buffer support 43, and a buffer pad 46 coaxially aligned with the printing roller is installed on the side mounting plate 45. The two buffer supports 43 simultaneously and mutually offset or approach each other to elastically clamp printing rollers of different lengths, which can reduce wear caused by rigid contact. The buffer pad 46 is coaxially aligned with the printing roller through the side mounting plate 45, so that the positioning reference of the buffer modules 40 on both sides coincides with the axis of the printing roller. The coaxial contact makes the force on the end of the printing roller evenly distributed along the axis, eliminating local stress concentration.

[0032] Furthermore, the top drive mechanism 4 also includes a top drive rack 47 arranged parallel to the top guide post 42. The top drive rack 47 is connected to the buffer support seat 43. The transverse drive seat 41 is equipped with a top drive gear 48 that is disposed between the two top drive racks 47 and simultaneously meshes with the two top drive racks 47. The transverse drive seat 41 is also equipped with a transverse telescopic drive member 49. The drive end of the transverse telescopic drive member 49 is connected to one of the buffer support seats 43.

[0033] In this embodiment, the top drive gear 48 meshes with two axially symmetrically arranged top drive racks 47. When one of the buffer support seats 43 moves, the other buffer support seat 43 is forced to drive synchronously, so that the two buffer support seats 43 move closer to the plate roller support seat 31 at the same time, or move away from the plate roller support seat 31 at the same time. The two ends of the plate roller of different sizes can be clamped according to the length of the plate roller.

[0034] The lateral telescopic drive component 49 is a telescopic cylinder arranged laterally. The telescopic cylinder's telescopic direction is aligned with the moving direction of the buffer support 43. When the telescopic cylinder drives one of the buffer support 43 to move, the other buffer support 43 moves synchronously under the cooperation of gear and rack transmission.

[0035] The telescopic cylinder supports PLC pulse signal control and can be linked with the central control system. It can automatically calculate the clamping stroke according to the preset roller specifications and parameters to achieve fully automatic centering and clamping, which is suitable for the full-process linkage requirements of intelligent production lines.

[0036] Preferably, there are two or more temporary storage stations 3, which can clamp and position two or more printing rollers at the same time, facilitating transfer.

[0037] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0038] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
