Description

Technical Field

[0001] The present application relates to the technical field of grinding devices, and in particular to a grinding device for a plate roller. Background Art

[0002] Currently, in the printing industry, especially in the production of printing rollers, printing roller grinding is a crucial process. Traditional printing roller grinding methods are mostly completed in two stages: coarse grinding and fine grinding. Each stage uses a different grinding head, which means that two independent systems are required for coarse grinding and fine grinding. During the processing, the grinding head needs to be switched according to the processing needs.

[0003] However, since switching the grinding head during the processing process takes a certain amount of time, the overall work efficiency is relatively low. Utility Model Content

[0004] In order to improve processing efficiency, the present application provides a grinding device for a plate roller.

[0005] The grinding device of a plate roller provided in this application adopts the following technical solution:

[0006] A grinding device for a plate roller includes a second body frame and a spindle module. The spindle module includes a lifting frame, a grinding and polishing wheel, and a first drive motor. The lifting frame is slidably connected to the second body frame in a vertical direction. The second body frame is provided with a first drive member for driving the lifting frame to move up and down. The grinding and polishing wheel is located at the lower part of the lifting frame and is rotatably connected to the lifting frame. The first drive motor is used to drive the grinding and polishing wheel to rotate.

[0007] By adopting the above technical solution, the lifting and lowering of the lifting frame is controlled by the first driving member, thereby controlling the lifting and lowering of the grinding and polishing wheel, and then controlling the force applied by the grinding and polishing wheel on the plate roller, thereby controlling the grinding and polishing wheel to perform rough polishing and fine polishing on the plate roller. Compared with the existing technology, the time for switching the grinding head can be saved, thereby improving the processing efficiency.

[0008] Optionally, the first driving member is a hydraulic cylinder, which is fixedly connected to the second fuselage frame. A first mounting block is fixedly connected to the piston rod of the hydraulic cylinder. Second mounting blocks are provided at both ends of the lifting frame, and the second mounting blocks are connected to the first mounting block.

[0009] By adopting the above technical solution, when the lifting frame needs to be driven to move up or down, the piston rod of the hydraulic cylinder moves, thereby controlling the lifting frame to move up or down.

[0010] Optionally, the first mounting block is provided with a second sliding groove, the length direction of the second sliding groove is vertically arranged, the second mounting block is slidably connected to the second sliding groove along the vertical direction, and the first mounting block is provided with a driving component for driving the second mounting block to slide.

[0011] By adopting the above technical solution, when grinding and polishing is required, the position of the grinding and polishing wheel is first roughly adjusted by the hydraulic cylinder, and then the second mounting block is finely adjusted by the drive assembly to control the pressure applied by the grinding and polishing wheel to the plate roller.

[0012] Optionally, the drive assembly includes a threaded rod and a second drive motor, the second drive motor is fixed to the first mounting block, the threaded rod is coaxially arranged on the output shaft of the second drive motor, and the threaded rod is threaded through the second mounting block.

[0013] By adopting the above technical solution, when the second mounting block needs to be fine-tuned, the second drive motor drives the threaded rod to rotate, thereby driving the second mounting block to move, thereby controlling the pressure applied by the grinding and polishing wheel to the plate roller.

[0014] Optionally, a first mounting plate is fixed on the first mounting block, the first mounting plate is located above the compression plate, and the second drive motor is fixedly mounted on the first mounting plate.

[0015] By adopting the above technical solution, the second drive motor is fixedly mounted on the first mounting plate, so that the second drive motor drives the threaded rod to rotate.

[0016] Optionally, the lower portion of the second sliding groove is closed to limit the lower limit sliding position of the second mounting block.

[0017] By adopting the above technical solution, the lower groove wall of the second sliding groove limits the second mounting block. In the initial state, the second mounting block abuts against the lower groove wall of the second sliding groove, and the hydraulic cylinder drives the lifting frame to slide downward so that the grinding and polishing wheel abuts against the plate roller. Thereafter, the position of the second mounting block can be adjusted to adjust the pressure applied by the grinding and polishing wheel on the plate roller.

[0018] Optionally, a first mounting portion is provided on the upper part of the grinding and polishing wheel, a second mounting portion is provided on the lower part of the output shaft of the first drive motor, first clamping blocks are provided on the circumferential walls on both sides of the upper part of the first mounting portion, a first limiting groove is provided in the middle part of the second mounting portion, the upper and lower ends of the first limiting groove are both closed, and an avoidance groove is provided at the lower part of the second mounting portion for the first clamping block to pass through, and the avoidance groove is connected to the first limiting groove.

[0019] By adopting the above technical solution, when installing the grinding and polishing wheel, the first clamping block is clamped in the first limiting groove through the avoidance groove, and then the grinding and polishing wheel is rotated so that the first clamping block is hooked in the first limiting groove, thereby limiting the vertical position of the grinding and polishing wheel.

[0020] Optionally, the groove wall of the first limiting groove is slidably connected to the second locking block, the side wall of the first locking block is provided with a second limiting groove for the second locking block to be locked, the first locking block is provided with a joystick, the joystick protrudes from the outer wall of the second mounting part, and the second mounting part is provided with a spring for forcing the second locking block to be locked in the second limiting groove.

[0021] By adopting the above technical solution, the second clamping block is clamped on the first clamping block, thereby limiting the rotation of the grinding and polishing wheel relative to the output shaft of the first drive motor.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The lifting frame is controlled by the first driving member to lift and lower the lifting frame, thereby controlling the lifting and lowering of the grinding and polishing wheel, and further controlling the force applied by the grinding and polishing wheel on the plate roller, thereby controlling the grinding and polishing wheel to perform rough polishing and fine polishing on the plate roller. Compared with the existing technology, the time of switching the grinding head can be saved, thereby improving the processing efficiency;

[0024] 2. When installing the grinding and polishing wheel, the first clamping block is clamped in the first limiting groove through the avoidance groove, and then the grinding and polishing wheel is rotated so that the first clamping block is hooked in the first limiting groove, thereby limiting the vertical position of the grinding and polishing wheel, and then the second clamping block is clamped on the first clamping block, thereby limiting the rotation of the grinding and polishing wheel relative to the output shaft of the first drive motor.

The cylinder body of the hydraulic cylinder 5 is fixedly connected to the upper wall of the second cavity 22. A first mounting block 51 is fixedly connected to the piston rod of the hydraulic cylinder 5. Second mounting blocks 412 are fixedly connected to both side walls of the lifting frame 41 near the hydraulic cylinder 5. First sliding grooves 23 are defined on both sides of the second fuselage frame 2. The ends of the first sliding grooves 23 are connected to the first sliding cavity 21 and the second cavity 22, respectively. The second mounting block 412 is slidably connected to the first sliding groove 23 and connected to the first mounting block 51.

[0033] Reference Figure 1 and Figure 2 A second sliding groove 52 is provided on the side of the first mounting block 51 close to the second connecting block. The length direction of the second sliding groove 52 is vertically arranged. The second mounting block 412 is connected to the second sliding groove 52 by sliding in the vertical direction. A driving component 6 is provided on the first mounting block 51 to drive the second mounting block 412 to slide.

[0034] Reference Figure 1 and Figure 2 The drive assembly 6 includes a threaded rod 62 and a second drive motor 61.

The output shaft of the second drive motor 61 is located at the bottom, and the threaded rod 62 is coaxially fixedly connected to the output shaft of the second drive motor 61. The threaded rod 62 is threaded through the second mounting block 412.

[0035] Reference Figure 1 and Figure 2 The lower portion of the second sliding groove 52 is closed to limit the lower limit sliding position of the second mounting block 412 .

[0036] Reference Figure 2 and Figure 3A first mounting portion 45 is coaxially fixedly connected to the upper portion of the grinding and polishing wheel 42. A second mounting portion 44 is coaxially fixedly connected to the lower end of the output shaft of the first drive motor 43. First retaining blocks 451 are fixedly connected to the circumferential walls on both sides of the upper portion of the first mounting portion 45. The two first retaining blocks 451 are symmetrically arranged around the axis of the first mounting portion 45. A first limiting groove 441 is defined in the middle portion of the second mounting portion 44. The upper and lower ends of the first limiting groove 441 are both closed. A through hole 442 is coaxially defined on the lower circumferential wall of the first limiting groove 441 for the first mounting portion 45 to pass through. A relief groove 443 is defined in the wall of the through hole 442 for the first retaining block 451 to pass through. The relief groove 443 is connected to the first limiting groove 441.

[0037] Reference Figure 2 and Figure 3 The walls of the first limiting groove 441 on both sides are formed with third sliding grooves 447 along the radial direction of the second mounting portion 44. The third sliding grooves 447 and the avoidance grooves 443 are offset from each other. The second mounting portion 44 is provided with a second engaging block 444 that is slidably connected to the third sliding grooves 447. The sidewalls of the first engaging block 451 are formed with second limiting grooves 452 for the second engaging block 444 to engage. When the second engaging block 444 is engaged in the second limiting grooves 452, a gap is still maintained between the side of the second engaging block 444 away from the first engaging block 451 and the inner wall of the second limiting groove 452.

[0038] Reference Figure 2 and Figure 3 The first locking block 451 is fixedly connected to the side of the axis of the second mounting portion 44 with an operating rod 445. The operating rod 445 slides through the second mounting portion 44 and protrudes from the outer peripheral wall of the second mounting portion 44. The second mounting portion 44 is provided with a spring 446 that forces the second locking block 444 to be clamped in the second limiting groove 452. The spring 446 is coaxially sleeved on the operating rod 445. One end of the spring 446 is fixedly connected to the second mounting portion 44. The end of the operating rod 445 away from the second mounting portion 44 is fixedly connected to the fixed block 448, and the other end of the spring 446 is fixedly connected to the fixed block 448.

[0039] Reference Figure 2 and Figure 3The fixing block 448 is semi-spherical in shape, with its curved surface facing away from the second mounting portion 44. The second mounting portion 44 is provided with a limiting bracket 46 for limiting the fixing block 448. The limiting bracket 46 is U-shaped, with its opening facing the second mounting portion 44. Both ends of the limiting bracket 46 are hinged to the outer wall of the second mounting portion 44, allowing the limiting bracket 46 to rotate up and down. The inner side of the limiting bracket 46 defines an arcuate groove 461 for the fixing block 448 to engage. With the fixing block 448 engaged in the arcuate groove 461, the limiting bracket 46 can limit the operating lever 445, thereby reducing the possibility of the second engaging block 444 disengaging from the second limiting groove 452 during rotation of the grinding wheel 42. The gap between the side of the second engaging block 444 away from the first engaging block 451 and the inner wall of the second limiting groove 452 is greater than the maximum depth of the arcuate groove 461.

[0040] The implementation principle of the grinding device for the plate roller in the embodiment of the present application is: the lifting and lowering of the lifting frame 41 is controlled by the hydraulic cylinder 5, thereby controlling the lifting and lowering of the grinding and polishing wheel 42, and then controlling the force applied by the grinding and polishing wheel 42 on the plate roller, thereby controlling the grinding and polishing wheel 42 to perform rough polishing and fine polishing on the plate roller. Compared with the existing technology, it can save the time of switching the grinding head, thereby improving the processing efficiency.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
