[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 provides a flexible plate-making and washing positioning clamping device:

[0023] Please see Figure 1 , Figure 2 The shell 10 has a bearing plate 20 inside, and the bearing plate 20 has multiple sets of support blocks. The multiple sets of support blocks are fixedly connected to the inner wall of the shell 10 by welding.

[0024] Please see Figure 3 , Figure 4 The pallet 30 is connected to the support plate 20 through multiple sets of movable parts 32. The vertical projection surface of the pallet 30 is completely located in the area of ​​the upper end surface of the support plate 20. The movable part 32 includes a guide rod 321 passing through the support plate 20. The top end of the guide rod 321 is connected to the support plate 20, and the bottom end of the guide rod 321 is connected to a limit block 322. A spring 323 is wound on the guide rod 321. The spring 323 is located between the limit block 322 and the support plate 20. The spring 323 is made of stainless steel. The pallet 30 can move up and down through the movable parts 32. When the pallet 30 moves upward, it pulls the guide rod 321 and compresses the spring 323. When the pallet 30 moves downward, it presses down the guide rod 321 and relaxes the spring 323.

[0025] Please see Figure 4 The housing 10 is equipped with a hydraulic push rod 14. The movable rod of the hydraulic push rod 14 is connected to a lifting block 15. The hydraulic push rod 14 can drive the lifting block 15 to move and push the pallet 30 upward. The hydraulic push rod 14 is made of stainless steel and has a corrosion-resistant sealing ring and is controlled by a controller. The lifting block 15 has a lifting slope. Several sets of contact pulleys 31 are provided on the lower side of the pallet 30. The movable rod of the hydraulic push rod 14 extends out and drives the lifting block 15 to move. The contact pulleys 31 move along the lifting slope, thereby moving the pallet 30 upward.

[0026] Please see Figure 2 The plate is placed on the pallet 30 for washing. After moving upward with the pallet 30, it is clamped by the clamping assembly 40, thus maintaining a flat and fixed state during the washing process. The clamping assembly 40 includes a first bushing 41 and a second bushing 42. The first bushing 41 is fixedly connected to the support plate 20, and the second bushing 42 is slidably fitted with the support plate 20. The second bushing 42 is connected to an adjusting rod 421 that extends laterally out of the housing 10. The adjusting rod 421 is screwed with an adjusting sleeve 422. Both the first bushing 41 and the second bushing 42 are provided with multiple sets of first pressure strips 43. Adjacent sets of first pressure strips 43 are spaced apart. The housing 10 has a sliding groove 13 for the adjusting rod 421 to pass through.

[0027] Sufficient blank margins around the board allow clamping assembly 40 to clamp it. During the clamping preparation process, the position of the second bushing 42 is first slidably adjusted so that the multiple sets of first pressure strips 43 on the first bushing 41 and the second bushing 42 are vertically aligned with the blank margins on one side of the board. To improve the alignment effect, linear spotlights can be installed on the first bushing 41 and the second bushing 42. The linear spotlights illuminate the light strip onto the board to facilitate alignment. After the adjustment is completed, the second bushing 42 is fixed by rotating the adjusting sleeve 422 to abut against the inner and outer walls of the housing 10.

[0028] The plate moves upward with the pallet 30. The blank edges on the left and right sides of the plate are clamped by multiple sets of first pressure strips 43 and the pallet 30. During manual plate washing, the solvent can flow out from the front and back sides of the plate or be discharged along the gaps formed by two adjacent sets of first pressure strips 43, dissolving and washing away unwanted resin to form a raised printing relief. After the plate washing is completed, the plate moves downward with the pallet 30 and is released from the clamps. It can be removed from the pallet 30 for subsequent drying and other processes. The plate can be directly picked up and put down, which is simple to operate and avoids the presence of tape residue on the plate, resulting in good plate washing quality.

[0029] Example 2, based on Example 1 above, provides a flexible plate-making and washing positioning clamping device:

[0030] Please see Figure 2 The edge of the support plate 20 and the inner wall of the shell 10 form multiple sets of drainage channels 21. A collection tank 11 is provided at the bottom of the shell 10. The collection tank 11 is connected to the outlet pipe 12. During plate washing, the solvent can enter the shell 10 along the drainage channel 21 and be collected through the collection tank 11 or discharged from the outlet pipe 12.

[0031] Please see Figure 3 A horizontal plate 16 is provided inside the shell 10, and a lifting block 15 is movably mounted on the horizontal plate 16. The horizontal plate 16 guides the movement of the lifting block 15.

[0032] Please see Figure 2 , Figure 4 The first bushing 41 and the second bushing 42 are respectively hinged to the two sides of the movable frame 44. The lower side of the movable frame 44 is provided with the second pressure strip 45. The movable frame 44 is screwed with the abutment rod 46. The movable frame 44 can be rotated and adjusted according to the size of the plate, so that the second pressure strip 45 can cooperate with the support plate 30 to clamp the front and rear sides of the plate. By rotating the abutment rod 46 to abut against the upper end surface of the support plate 30, the rotation of the movable frame 44 is restricted, and the movable frame 44 will not deflect during the clamping process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
