Description

Technical Field

[0001] The utility model relates to the technical field of embossing processing, and more specifically, to an embossing roller with a customizable surface. Background Art

[0002] An embossing roller is a cylindrical embossing body on a printing press. The embossing roller is the most important roller in an offset printing press. Its surface has high machining accuracy, is acid, alkali, and corrosion-resistant, and its cylinder body also has high rigidity and strength, capable of resisting impact and vibration. A gripper mechanism is installed at the non-printing area of the roller. The embossing roller is mainly used in modern offset printing presses to support paper, complete printing, and transfer paper. The embossing roller is the adjustment reference for the kinematic relationship of other machine parts.

[0003] Currently, on the market, the roller of the embossing roller and the printing plate are connected by bolts. The bolts are inserted from the side of the printing plate pattern into the reserved holes aligned with the roller and rotated to make the printing plate closely attached to the outer wall of the roller. However, when replacing the printing plate, since the position of the reserved holes remains unchanged, the reserved holes corresponding to different patterns of the printing plate may appear in the middle of the pattern, and the pattern may be scratched during the operation, resulting in an unsatisfactory embossing effect or even embossing failure. Therefore, we propose an embossing roller with a customizable surface. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide an embossing roller with a customizable surface to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present utility model provides an embossing roller with a customizable surface, including a roller. A chute is opened in the middle of the front end of the roller. A plurality of sliders are connected inside the chute. The top of the slider is fixedly connected with a push rod. A groove is opened at the top of the rear side of the chute. A push block is slidably connected inside the groove. The bottom inclined surface of the push block contacts the top of the push rod. The front end of the push block is fixedly connected with a pressing plate. A square block slides in the middle of the chute. A printing plate is fixedly connected to the outside of the square block.

[0006] As a further improvement of this technical solution, clamping grooves are opened on both the left and right sides of the chute. Clamping plates are fixedly connected to both the left and right sides of the slider. The size of the clamping plate corresponds to the size of the clamping groove.

[0007] As a further improvement of this technical solution, the upper side and the lower side of the chute are symmetrically distributed about the center of the roller, and the bottom of the slider is an inclined surface.

[0008] As a further improvement of this technical solution, a spring is fixedly connected to the top of the slider. The spring is sleeved on the outer surface of the push rod. The other end of the spring is fixedly connected to a baffle. The baffle is fixedly connected to the inner wall of the chute. The push rod penetrates through the baffle.

[0009] As a further improvement of this technical solution, an arc plate is fixedly connected to the inner wall of the printing plate. The arc plate extends out of the inner wall of the printing plate, and the printing plate is located outside the arc plate.

[0010] As a further improvement of this technical solution, the pressing plate is of a "semicircular" structure. When the pressing plate presses the arc plate, the height of the pressing plate is lower than that of the printing plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For this surface-customizable embossing roller, when replacing the printing plate, align the square block on the inner wall of the printing plate with the middle of the sliding groove, press the printing plate, and the square block pushes the sliders upward and downward along the inclined surfaces of the sliders respectively. The sliders drive the push rods to move upward, and the push rods push the push blocks backward along the inclined surfaces at the bottoms of the push blocks. The push blocks drive the pressing plates to press the arc plates, thereby limiting and fixing the printing plate in the front-back direction. When the sliders move, the springs are compressed, and under the action of the elastic force of the springs, the sliders clamp the square blocks, thereby limiting and fixing the printing plate in the up-down direction. The sliding grooves limit the square blocks in the left-right direction, thereby limiting and fixing the printing plate in the left-right direction, avoiding the influence of using reserved holes on the printing plate, thus ensuring that the printing plate can maintain a stable state and promoting the normal progress of the printing work.

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

[0021] The impression cylinder is a cylindrical impression body on a printing press. The impression cylinder is the most important cylinder in an offset printing press. Its surface has high machining accuracy, is acid, alkali, and corrosion-resistant, and its cylinder body also has high rigidity and strength, capable of resisting impact and vibration. A gripper mechanism is installed at the non-printing part of the cylinder. The impression cylinder is mainly used in modern offset printing presses to support paper, complete printing, and transfer paper. The impression cylinder is the adjustment reference for the kinematic relationship of other machine parts. Please refer to Figures 1 - 5 As shown, the present utility model provides an impression cylinder with a customizable surface, including a roller 1. A chute 11 is provided in the middle of the front end of the roller 1. A plurality of sliders 2 are connected inside the chute 11. A push rod 21 is fixedly connected to the top of the slider 2. A groove 13 is provided at the top of the rear side of the chute 11. A push block 24 is slidably connected inside the groove 13. The bottom inclined surface of the push block 24 contacts the top of the push rod 21. A pressing plate 25 is fixedly connected to the front end of the push block 24. A square block 32 slides in the middle of the chute 11. A printing plate 3 is fixedly connected to the outside of the square block 32.

[0022] The improvement of the present utility model lies in:

[0023] Since the cylinder of the impression cylinder commonly existing in the market is connected to the printing plate 3 by bolts, the bolts are inserted from the side of the pattern of the printing plate 3 into the reserved holes aligned with the cylinder and rotated to make the printing plate 3 closely attached to the outer wall of the cylinder. However, when replacing the printing plate 3, since the position of the reserved holes remains unchanged, the reserved holes corresponding to different patterns of the printing plate 3 will appear in the middle of the pattern, and pattern scratches may occur during the operation process, resulting in an unsatisfactory impression effect or even impression failure. When replacing the printing plate 3, align the square block 32 on the inner wall of the printing plate 3 with the middle of the chute 11, press the printing plate 3, the square block 32 respectively pushes the sliders 2 upward and downward along the inclined surface of the slider 2, the slider 2 drives the push rod 21 to move upward, the push rod 21 pushes the push block 24 backward along the bottom inclined surface of the push block 24, and the push block 24 drives the pressing plate 25 to press the arc plate 31, thereby limiting and fixing the printing plate 3 in the front and rear directions. When the slider 2 moves, the spring 23 is compressed, and under the action of the elastic force of the spring 23, the slider 2 clamps the square block 32, thereby limiting and fixing the printing plate 3 in the up and down directions. The chute 11 limits the square block 32 in the left and right directions, thereby limiting and fixing the printing plate 3 in the left and right directions, avoiding the influence of the reserved holes on the printing plate 3, ensuring that the printing plate 3 can maintain a stable state, and promoting the normal progress of the printing work.

[0024] In order to ensure that the slider 2 only slides up and down within the chute 11, therefore, clamping grooves 12 are provided on both the left and right sides of the chute 11, clamping plates 26 are fixedly connected to both the left and right sides of the slider 2, the size of the clamping plate 26 corresponds to the size of the clamping groove 12, and the clamping plate 26 slides within the clamping groove 12 to horizontally limit the slider 2, thereby ensuring that the slider 2 only slides up and down.

[0025] Considering that it is more convenient to push the square 32 of the printing plate 3 between the sliders 2, therefore, the upper side and the lower side of the chute 11 are symmetrically distributed about the center of the roller 1, the bottom of the slider 2 is an inclined surface, and the square 32 pushes the slider 2 upward and downward along the inclined surface of the slider 2 respectively, thereby ensuring that the square 32 of the printing plate 3 can be more conveniently pushed between the sliders 2.

[0026] In order to better limit and fix the printing plate 3 in the up and down directions, therefore, a spring 23 is fixedly connected to the top of the slider 2, the spring 23 is sleeved on the outer surface of the push rod 21, the other end of the spring 23 is fixedly connected to the baffle 22, the baffle 22 is fixedly connected to the inner wall of the chute 11, the push rod 21 penetrates through the baffle 22, and the square 32 pushes the slider 2 upward and downward along the inclined surface of the slider 2 respectively to compress the spring 23. Under the action of the elastic force of the spring 23, the slider 2 is pushed to clamp and fix the square 32.

[0027] Considering that it is possible to better limit and fix the printing plate 3 in the front and rear directions, therefore, an arc plate 31 is fixedly connected to the inner wall of the printing plate 3, the arc plate 31 extends out of the inner wall of the printing plate 3, the printing plate 3 is located outside the arc plate 31, and the pressing plate 25 presses the arc plate 31 to limit and fix the printing plate 3 in the front and rear directions and ensure the stability of the printing plate 3.

[0028] In order to prevent the pressing plate 25 from affecting the printing plate 3 during printing, therefore, the pressing plate 25 has a "semicircular" structure. When the pressing plate 25 presses the arc plate 31, the height of the pressing plate 25 is lower than that of the printing plate 3, so as to ensure that only the printing plate 3 contacts the item to be printed during printing, thereby improving the printing quality.

[0029] In summary, the working principle of this solution is as follows:

[0030] For the surface-customizable embossing cylinder, when replacing the printing plate 3, align the square 32 on the inner wall of the printing plate 3 with the middle of the sliding groove 11, press the printing plate 3, the square 32 pushes the slider 2 upward and downward along the inclined surface of the slider 2 respectively, the slider 2 drives the push rod 21 to move upward, the push rod 21 pushes the push block 24 backward along the inclined surface at the bottom of the push block 24, and the push block 24 drives the pressing plate 25 to press the arc plate 31, so as to limit and fix the printing plate 3 in the front and rear directions. When the slider 2 moves, the spring 23 is compressed, and under the action of the elastic force of the spring 23, the slider 2 clamps the square 32, so as to limit and fix the printing plate 3 in the up and down directions. The sliding groove 11 limits the square 32 in the left and right directions, so as to limit and fix the printing plate 3 in the left and right directions, avoiding the influence of the reserved holes on the printing plate 3, thus ensuring that the printing plate 3 can maintain a stable state and promoting the normal progress of the printing work.
