Description

Technical Field

[0001] The utility model relates to the technical field of printing press plate clamps, in particular to a printing press plate clamp with stable limit. Background Technique

[0002] A printing press plate clamp, also known as a printing press plate table or plate bed, is an important component of a printing press, mainly used to fix printing plates (such as copper plates, zinc plates, etc.), ensuring the stability of the printing plate during the printing process, thereby guaranteeing the printing quality.

[0003] When the existing printing press plate clamp clamps the printing plate, in order to facilitate clamping the printing plate, usually a set of driving mechanisms are used to drive the plate clamp top plate at the top. This results in only a certain position on the top of the plate clamp top plate being subjected to a force, so that the pressures received on the plate clamp top plate are different. Therefore, when clamping the printing plate, the clamping is unstable, and it is easy to have a good clamping effect in the middle and a poor clamping effect on both sides. Content of the Utility Model

[0004] The purpose of the utility model is to provide a printing press plate clamp with stable limit to solve the problem that the currently used printing press plate clamp is prone to unstable clamping when clamping the printing plate proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A printing press plate clamp with stable limit, including: a plate clamp bottom plate and a plate clamp top plate. Side plates are installed on both sides of the plate clamp bottom plate, and the plate clamp top plate is arranged on the top of the plate clamp bottom plate;

[0006] Sliders are installed on both sides of the plate clamp top plate. A fixed block is installed on the top of the plate clamp top plate. A connecting block is connected through an inclined groove in the middle of the fixed block. One side of the connecting block is connected with a connecting rod, and a screw sleeve is installed on the top of the connecting rod.

[0007] Preferably, a lead screw runs through the middle of the screw sleeve, and one side of the lead screw is connected with a driving motor through a coupling.

[0008] Preferably, a guide block is installed on the top of the screw sleeve, and a polished rod runs through the middle of the guide block.

[0009] Preferably, a convex block is installed on the outside of the slider.

[0010] Preferably, a rotating rod is connected through a shaft at the notch on one side of the convex block, and an adapter block is installed at the bottom of the rotating rod.

[0011] Preferably, a clamping block is inserted through the middle of the adapter block, and a movable spring is installed between the clamping block and the groove of the convex block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the printing press plate clamp with stable limit is in use, the printing plate can be placed between the top plate of the plate clamp and the bottom plate of the plate clamp. Then, the driving motor is started, and through the lead screw, the nut sleeve drives the connecting rod and the connecting block to slide, and the connecting block pulls the fixing block downward through the inclined groove. By the downward movement of the fixing block, the top plate of the plate clamp can be driven to move downward. At this time, the printing plate can be clamped in cooperation with the top plate of the plate clamp and the bottom plate of the plate clamp. Since four groups of fixing blocks are symmetrically installed, the pressure received by the top of the top plate of the plate clamp is the same. At the same time, relying on the sliders on both sides of the top plate of the plate clamp, the top plate of the plate clamp can more stably clamp and limit the printing plate. This is the usage feature of the printing press plate clamp with stable limit.

[0013] 1. For the printing press plate clamp with stable limit, when it is necessary to stably clamp and limit the printing plate, through the cooperation of the lead screw and the nut sleeve, the connecting rod and the connecting block can be driven to move, and the top plate of the plate clamp can be driven to move through the fixing block. With the cooperation of the four groups of fixing blocks and the sliders on both sides of the top plate of the plate clamp, the top plate of the plate clamp moves more stably during movement, so that the top plate of the plate clamp can more stably clamp and limit the printing plate.

[0014] 2. For the printing press plate clamp with stable limit, when it is necessary to replace the top plate of the plate clamp, only need to push the clamping block into the inside of the convex block, so that the clamping block does not limit the rotating rod through the connecting block. Then the rotating rod can be rotated, so that the rotating rod does not limit the slider in the groove of the convex block on the side of the top plate of the plate clamp. Thus, the top plate of the plate clamp can be quickly disassembled from between the two sliders. On the contrary, through the convex block and the rotating rod, the top plate of the plate clamp can be limited in the two sliders, which is convenient for quickly replacing and installing the top plate of the plate clamp.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 , the present invention provides a technical solution: a printing press plate clamp with stable limit, including: a plate clamp bottom plate 1 and a plate clamp top plate 3. Side plates 2 are installed on both sides of the plate clamp bottom plate 1, and the plate clamp top plate 3 is arranged on the top of the plate clamp bottom plate 1;

[0022] Sliders 4 are installed on both sides of the plate clamp top plate 3, a fixed block 5 is installed on the top of the plate clamp top plate 3, a connecting block 6 is connected through an inclined groove in the middle of the fixed block 5, a connecting rod 7 is connected to one side of the connecting block 6, a screw sleeve 8 is installed on the top of the connecting rod 7, a lead screw 9 is connected through the middle of the screw sleeve 8, a driving motor 10 is connected to one side of the lead screw 9 through a coupling, a guide block 11 is installed on the top of the screw sleeve 8, and a smooth rod 12 is connected through the middle of the guide block 11. The smooth rod 12 is installed between the two side plates 2.

[0023] During specific implementation, for the printing press plate clamp with stable limit, when it is necessary to stably clamp the printing plate, the printing plate can be placed between the plate clamp bottom plate 1 and the plate clamp top plate 3, and then the driving motor 10 is started. The driving motor 10 will drive the lead screw 9 to rotate through the coupling. Four screw sleeves 8 are sleeved on the outer side of the lead screw 9, and a guide block 11 is installed on the top of the screw sleeve 8. The guide block 11 slides on the outer side of the smooth rod 12. Therefore, under the guiding action of the guide block 11 and the smooth rod 12 on the screw sleeve 8, when the lead screw 9 rotates, it will drive the screw sleeve 8 to slide along the lead screw 9;

[0024] A connecting rod 7 is also connected to the bottom of the screw sleeve 8, and a connecting block 6 is connected to one side of the connecting rod 7. The connecting block 6 is slidably connected in the inclined groove of the fixed block 5. Under the action of the screw sleeve 8, the connecting rod 7 will drive the connecting block 6 to move to the right. When the connecting block 6 moves to the right, the connecting block 6 will move to the right along the inclined groove of the fixed block 5. Affected by the inclined groove formed through the middle of the fixed block 5, the connecting block 6 will pull the fixed block 5 to move downward through the inclined groove, and the downward movement of the fixed block 5 will drive the plate clamp top plate 3 at the bottom to move downward. At the same time, during the downward movement of the plate clamp top plate 3, it will slide along the sliding groove of the side plate 2 through the sliders 4 on both sides. Through the sliders 4, the stability of the plate clamp top plate 3 during movement can be increased. At this time, in cooperation with the plate clamp bottom plate 1, the printing plate can be clamped between the plate clamp bottom plate 1 and the plate clamp top plate 3. Since four groups of the fixed blocks 5 are evenly installed along the top of the plate clamp top plate 3, the force on the plate clamp top plate 3 can be made more uniform, so that the plate clamp top plate 3 can more stably clamp and limit the printing plate.

[0025] Refer to Figure 1 With Figure 4 As can be seen, during use, the printing plate can be placed between the plate clamp top plate 3 and the plate clamp bottom plate 1, and then through the cooperation of the driving motor 10 and the lead screw 9, the screw sleeve 8 drives the connecting rod 7 and the connecting block 6 to move, and through the cooperation of the connecting block 6 and the inclined groove in the middle of the fixed block 5, the plate clamp top plate 3 is driven to move downward. Through the plate clamp top plate 3 and the plate clamp bottom plate 1, the printing plate can be stably clamped and limited, thereby increasing the stability of the printing plate.

[0026] A convex block 13 is installed on the outer side of the slider 4. A rotating rod 14 is connected to the notch on one side of the convex block through a rotating shaft. A connecting block 15 is installed at the bottom of the rotating rod 14. A clamping block 16 is inserted through the middle of the connecting block 15. An active spring 17 is installed between the clamping block 16 and the groove of the convex block 13. The clamping block 16 forms a telescopic structure with the convex block 13 through the active spring 17.

[0027] During specific implementation, for the printing press plate clamp with stable limit, when the plate clamp top plate 3 needs to be replaced, the clamping block 16 can be pushed into the interior of the convex block 13, and the active spring 17 in the groove of the convex block 13 will be compressed. The movement of the clamping block 16 will move out of the through groove in the middle of the connecting block 15, so that the clamping block 16 does not exert pressure on the rotating rod 14 through the connecting block 15. Then the rotating rod 14 can be rotated outward from the convex block 13 through the rotating shaft, so that the rotating rod 14 does not limit the slider 4 in the convex block 13 on the side of the plate clamp top plate 3. At this time, the plate clamp top plate 3 can be pushed, so that the slider 4 moves out of the notch on the side of the convex block 13, thus facilitating the quick removal of the plate clamp top plate 3 from between the two sliders4.

[0028] When installing the top plate 3 of the plate clamp, it is only necessary to align the notch position of the convex block 13 on the side of the top plate 3 of the plate clamp with the slider 4, and then push the top plate 3 of the plate clamp in the direction of the slider 4, so that the slider 4 is docked into the convex block 13 through the notch position of the convex block 13. At this time, the rotary rod 14 can be rotated in the reverse direction, so that the rotary rod 14 limits the slider 4 in the notch of the convex block 13. When the rotary rod 14 drives the connecting block 15 to rotate to a vertical state, then release the clamping block 16, and the clamping block 16 will be inserted into the connecting block 15 through the reset action of the movable spring 17. By passing the clamping block 16 through the through hole of the connecting block 15, the rotary rod 14 can be limited, thus facilitating the quick fixing of the slider 4 in the convex block 13 on the side of the top plate 3 of the plate clamp. At this time, the top plate 3 of the plate clamp can be installed in the two groups of sliders 4.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that during use, the top plate 3 of the plate clamp can be quickly fixed between the two groups of sliders 4 through the convex block 13 and the rotary rod 14 according to the usage requirements, thus facilitating the user to quickly replace the damaged top plate 3 of the plate clamp.

[0030] In summary: When using this printing press plate clamp with stable limit, it is only necessary to start the drive motor 10, so that the drive motor 10 makes the connecting rod 7 and the connecting block 6 move through the cooperation of the lead screw 9 and the nut sleeve 8. Then the connecting rod 7 and the connecting block 6 will drive the top plate 3 of the plate clamp to move upward through the fixed block 5. Without the extrusion and clamping of the printing plate by the top plate 3 of the plate clamp and the bottom plate 1 of the clamping plate, the printing plate can be quickly removed from the inside of the printing press, thus facilitating the quick replacement of the printing plate inside the printing press. Conversely, the printing plate can be clamped and fixed between the bottom plate 1 of the plate clamp and the top plate 3 of the plate clamp. This is the usage feature of this printing press plate clamp with stable limit. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
