Description

Technical Field

[0001] The utility model belongs to the technical field of gravure printing plate rollers, and particularly relates to a device for processing holes at both ends of a gravure printing plate roller. Background Art

[0002] In the gravure printing industry, the processing quality of plugging the holes at both ends of the plate roller directly affects the printing effect and the service life of the plate roller. However, the existing gravure plate roller plugging processing devices have some significant technical limitations and operational difficulties, which seriously restrict the processing efficiency and accuracy.

[0003] First of all, the existing technology generally has the problem of being unable to achieve synchronous processing when plugging the holes at both ends of the plate roller. This means that one end must be processed first, and then the position of the plate roller must be adjusted to process the other end. This asynchronous processing method not only greatly prolongs the processing time, but may also lead to inconsistent processing accuracy at both ends. Since the plate roller needs to be adjusted multiple times, the operation complexity is increased, and the risk of error is also increased. This processing method not only reduces production efficiency, but may also affect the quality consistency of the final product and have a negative impact on the printing effect.

[0004] Secondly, when processing both ends of the plate roller, the existing technology often lacks the ability to flexibly clamp plate rollers of different diameters. The diameter range of the plate rollers used in the gravure printing industry is relatively wide, and the fixed clamping mechanism is difficult to adapt to this diversity. This means that every time a plate roller of a different diameter is replaced, the clamping device needs to be replaced, which greatly increases the equipment debugging time and complexity. This not only reduces production efficiency, but may also affect the clamping accuracy due to frequent replacement, thereby affecting the processing quality. The lack of flexibility of the clamping mechanism also limits the versatility of the equipment. It may be necessary to equip multiple sets of processing equipment for plate rollers of different specifications, increasing the company's equipment investment cost.

[0005] In addition, the existing technology has a serious problem of manual dependence in the clamping process of the plate roller. The operator needs to manually support the plate roller and strive to keep the plate roller and the clamping sleeve in a concentric position before performing the clamping operation. This method is not only time-consuming and labor-intensive, but also places high demands on the operator's skills and experience. Manual operation is prone to introduce human errors, affecting the clamping accuracy and processing quality. Long-term repetitive physical labor is also prone to cause operator fatigue, increasing work safety risks. In addition, this manual operation method is difficult to ensure the consistency of each clamping, which may lead to quality fluctuations in mass production.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] The purpose of the utility model is to provide a device for plugging holes at both ends of a gravure printing plate roller, so as to solve the problems existing in the prior art in the background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] The top end of the piston rod is connected with the cylinder pressure bar, and the top end of the piston rod is connected with the cylinder pressure bar.

[0010] Preferably, a sliding rod is fixed on the base, and the lifting block is slidably connected to the sliding rod.

[0011] Preferably, a push spring is connected to one end of the connecting block, and a clamping plate is connected to the other end of the push spring.

[0012] Preferably, anti-slip strips are connected to the outer side of the control sleeve and the inner side of the clamping plate.

[0013] Preferably, the processing device includes a processing assembly, a sliding frame and a sliding seat. The sliding frame and the sliding seat are both slidably arranged above the base. The processing assembly is detachably mounted on the sliding frame, and the clamping sleeve is fixedly mounted on the sliding seat. The processing assembly setting can realize processing of both ends and improve processing efficiency.

[0014] Preferably, a screw is provided on the base, and the screw is rotatably mounted on the base. The sliding frame and the sliding seat are respectively movably connected to the corresponding screw through threads, and opposite threads are symmetrically provided at both ends of the screw. The setting of the screw makes it possible to achieve synchronous processing at both ends, thereby improving processing accuracy and processing efficiency.

[0015] Preferably, a slider is connected to the bottom of the sliding frame and the sliding seat, and a corresponding sliding groove is opened on the base. The sliding groove is adapted to the slider. The setting of the slider and the sliding groove improves the stability of the movement of the sliding frame and the sliding seat.

[0016] Preferably, the seat is detachably provided with a motor and a reducer, the reducer input end is connected to the motor output end, and the reducer output end is connected to one end of the screw, and the arrangement of the motor and the reducer provides stable power output.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The processing device of the present invention realizes synchronous processing of both ends of the gravure printing plate roller by setting up a symmetrical sliding frame and processing assembly. This design overcomes the limitation of traditional technology that both ends of the plate roller cannot be processed simultaneously, and greatly improves the processing efficiency. The sliding frame is driven by a screw and can accurately control the movement of the processing assembly to ensure the consistency and accuracy of the processing at both ends. The coordinated use of the motor and the reducer provides a stable and controllable power output for the processing process, further improving the processing quality. The design of the slider and the slide groove enhances the stability of the entire system, reduces the vibration during the processing, and thus improves the processing accuracy.

[0019] (2) The innovative design of the clamping device of the utility model solves the problem of flexible clamping of plate rollers of different diameters. Through the ingenious coordination of the guide block, guide sleeve, screw and clamping sleeve and other components, the precise positioning and clamping of the plate roller is achieved. The linkage mechanism between the control sleeve and the driving wheel and the driven wheel enables the operator to easily adjust the clamping force to adapt to plate rollers of different diameters. The design of the push spring and the clamping plate ensures the stability and uniformity during the clamping process. The application of the anti-slip strip further enhances the clamping effect. This design not only improves the flexibility and accuracy of clamping, but also greatly reduces the debugging time when replacing plate rollers of different specifications.

[0020] (3) The design of the lifting device of the utility model cleverly solves the problem of manual lifting of the plate roller. Through the combination of the cylinder, the piston rod and the lifting block, the plate roller is automatically lifted and positioned. The setting of the slide bar ensures the smoothness and accuracy of the lifting process. This automatic lifting mechanism not only reduces the labor intensity of the operator, but also significantly improves the accuracy of the plate roller positioning. The controllability of the cylinder enables the plate roller to accurately maintain a concentric position with the clamping sleeve, greatly improving the accuracy of subsequent clamping and processing.

The driven wheel 10 is fixedly connected to the outside of the screw 7. The driving wheel 11 is fixedly connected to one side of the control sleeve 9, and the driving wheel 11 is engaged with the driven wheel 10. The guide groove 12 is opened inside the guide sleeve 6, and the connecting block 13 is fixedly connected to one side of the guide block 5.

[0031] A slide bar 14 is fixed to the base 1, and the lifting block 2 is slidably connected to the slide bar 14. A push spring 15 is connected to one end of the connecting block 13, and the other end of the push spring 15 is connected to a clamping plate 16. Anti-slip strips 17 are connected to the outside of the control sleeve 9 and the inside of the clamping plate 16.

[0032] When it is necessary to clamp the plate roller, first make the sliding seat 20 drive the clamping sleeve 8 to move to the two ends farthest apart, and then place the plate roller on the lifting block 2 so that the center line of the plate roller is aligned with the center line of the lifting block 2, and then synchronously open the two cylinders 3 so that the cylinder 3 drives the piston rod 4 connected to the output end to move, and then the piston rod 4 will drive the lifting block 2 to move along the sliding rod 14, so that the lifting block 2 drives the plate roller placed above to move. When the plate roller and the clamping sleeve 8 are in a concentric position, close the cylinder 3, and then make the sliding seat 20 drive the clamping sleeve 8 to move to the corresponding position outside the plate roller, so that the clamping sleeve 8 is set to the outside of the plate roller, and then rotate the control sleeve 9 in the corresponding direction. The control sleeve 9 will drive the driving wheel 11 connected to one side to rotate, and then the driving wheel 11 will drive each driven wheel 1 engaged with it. 0 rotates, and then the driven wheel 10 drives the screw rod 7 to rotate, and then the guide sleeve 6 drives the guide groove 12 to slide along the screw rod 7. Due to the special structural design of the guide groove 12 and the guide block 5, when the guide groove 12 moves with the guide sleeve 6, the guide block 5 drives the connecting block 13 to move inward, and then the connecting block 13 drives the push spring 15 and the clamping plate 16 to gather inward, so that the inner wall of the clamping plate 16 contacts the outer wall of the plate roller, and then the connecting block 13 and the clamping plate 16 press the push spring 15 tightly, so that the push spring 15 applies a pressing force to the clamping plate 16, so that the clamping plate 16 clamps the plate roller. At the same time, the anti-slip strip 17 arranged on the inner side of the clamping plate 16 increases the friction with the outer surface of the plate roller, further enhancing the stability after clamping. When the plate roller is completely clamped, stop rotating the control sleeve 9.

[0033] In this embodiment, the processing device includes a processing assembly 18, a sliding frame 19, and a sliding seat 20. Both the sliding frame 19 and the sliding seat 20 are slidably mounted above the base 1. The processing assembly 18 is detachably mounted on the sliding frame 19, and the clamping sleeve 8 is fixedly mounted on the sliding seat 20. A lead screw 21 is provided on the base 1 and is rotatably mounted on the base 1. The sliding frame 19 and the sliding seat 20 are each movably connected to the corresponding lead screw 21 via threads, and the lead screw 21 has symmetrically opposite threads at both ends.

[0034] When the position of the clamping sleeve 8 needs to be moved, the motor 24 arranged in the middle is turned on. After the deceleration effect of the reducer 25, the motor 24 drives the screw 21 connected to the output end of the reducer 25 to rotate, and then the sliding seat 20 drives the slider 22 to slide along the slide groove 23. At the same time, the two sliding seats 20 will respectively drive the clamping sleeve 8 installed on the top to move in opposite directions. When the position of the clamping sleeve 8 is adjusted, the plate roller is stably clamped and the processing of the two ends of the plate roller is started. Then, the two motors 24 installed symmetrically on both sides are synchronously turned on. Then, the two motors 24 drive the screw 21 connected to the output end of the corresponding reducer 25 to rotate after the deceleration effect of the reducer 25, and then the sliding frame 19 drives the sliders 22 connected on both sides below to slide along the corresponding slide groove 23.

When the plate roller and the clamping sleeve 8 are in a concentric position, close the cylinder 3, and then make the sliding seat 20 drive the clamping sleeve 8 to move to the corresponding position outside the plate roller, so that the clamping sleeve 8 is set to the outside of the plate roller, and then rotate the control sleeve 9 in the corresponding direction. The control sleeve 9 will drive the driving wheel 11 connected to one side to rotate, and then the driving wheel 11 will drive each one meshing with it When the driven wheel 10 is engaged, it rotates, and then the driven wheel 10 drives the screw 7 to rotate, and then the guide sleeve 6 drives the guide groove 12 to slide along the screw 7. Due to the special structural design of the guide groove 12 and the guide block 5, when the guide groove 12 follows the movement of the guide sleeve 6, the guide block 5 drives the connecting block 13 to move inward, and then the connecting block 13 drives the push spring 15 and the clamping plate 16 to gather inward, so that the inner wall of the clamping plate 16 contacts the outer wall of the plate roller, and then the connecting block 13 and the clamping plate 16 will press the push spring 15 tightly, so that the push spring 15 applies a clamping force to the clamping plate 16, so that the clamping plate 16 clamps the plate roller, and at the same time, the anti-slip strip 17 arranged on the inner side of the clamping plate 16 increases the friction with the outer surface of the plate roller, further enhancing the stability after clamping. When the plate roller is completely clamped, stop rotating the control sleeve 9.

[0036] When the position of the clamping sleeve 8 needs to be moved, the motor 24 arranged in the middle is turned on. After the deceleration effect of the reducer 25, the motor 24 drives the screw 21 connected to the output end of the reducer 25 to rotate, and then the sliding seat 20 drives the slider 22 to slide along the slide groove 23. At the same time, the two sliding seats 20 will respectively drive the clamping sleeve 8 installed on the top to move in opposite directions. When the position of the clamping sleeve 8 is adjusted, the plate roller is stably clamped and the processing of the two ends of the plate roller is started. Then, the two motors 24 installed symmetrically on both sides are synchronously turned on. Then, the two motors 24 drive the screw 21 connected to the output end of the corresponding reducer 25 to rotate after the deceleration effect of the reducer 25, and then the sliding frame 19 drives the sliders 22 connected on both sides below to slide along the corresponding slide groove 23. Then, the sliding frame 19 will respectively drive the processing assembly 18 installed on the top to move inward. At the same time, the processing assembly 18 installed on the sliding frame 19 is opened, so that the processing assembly 18 starts to run, and then cooperates with the sliding frame 19 to move slowly, so as to realize the synchronous processing of the two ends of the plate roller.
