[0002] Printed materials can be seen everywhere in daily life, such as books, packaging boxes, etc. In the printing process, due to many steps, the stacked papers will be fluffy, that is, there is a gap between the papers, and they are not tightly attached, so they may move relative to each other during transportation. Therefore, it is necessary to press the papers of printed materials such as boxes and book blocks to facilitate cutting or binding.

[0003] The patent (CN202020353135.7) discloses a flattening and shaping device for printed materials, including an operating chamber, a bracket, and a workbench. A conveyor belt with a conveying direction from right to left is provided in the middle section of the work, and a first support platform and a second support platform are provided on the workbench respectively. A scraping mechanism is provided on the bracket above the conveyor belt, and bristles are provided in the scraping mechanism; a pre-flattening mechanism is provided on the first support platform, and a leveling mechanism is provided on the second support platform. The leveling mechanism is provided with an adjustment rod and a second pressure roller whose height is adjusted by the adjustment rod.

[0004] The equipment in the above patent document is driven by a cylinder. However, during the long-term use of the equipment, the piston rod of the cylinder and the inner side of the front end cover of the cylinder are prone to wear and aging, and the reciprocating movement of the piston inside the cylinder body causes wear, which can easily damage the cylinder. Therefore, the cylinder needs to be regularly maintained and replaced. When the staff disassembles the cylinder, since the cylinder and the equipment are fixedly connected by bolts and nuts, tools such as wrenches are required for disassembly. However, the cylinder is located in the middle position of the top of the equipment, and because the height of the equipment itself is not much different from that of an ordinary person, the staff will tiptoe or use tools to shorten the distance to the cylinder, and then use a wrench to turn the nut. However, the bolts are located at the bottom of the cylinder and the operating space is small. The staff often feel inconvenient during this operation, which cannot meet the needs of the staff.

[0024] like Figure 2-Figure 3 The printed anti-scratch clamp with easy maintenance shown in the figure, the locking mechanism 5 includes a locking box 50 fixedly connected to the bottom end of the support frame 2, and locking members 51 are symmetrically arranged on the left and right sides of the inner wall of the locking box 50, and the locking member 51 includes a first gear 52 and two second gears 53 that are rotatably connected, and the two second gears 53 are respectively meshed and connected to the two sides of the first gear 52, and a rotating column 54 is slidably inserted at the top center of the second gear 53, and a thread groove matching the bolt 4 is opened at the top of the rotating column 54, and the threads of the inner walls of the two thread grooves are in opposite directions, and a rotating disk 55 that is rotatably connected is arranged at the bottom of the locking box 50, and the rotating disk 55 is fixedly connected to the center of the outer wall of the first gear 52 through a transmission rod 56 The end of the transmission rod 56 away from the top of the first gear 52 is rotatably connected to the top of the inner wall of the locking box 50. The transmission rod 56 is located between the first gear 52 and the bottom of the inner wall of the locking box 50, and is fixedly connected to the surface of the third gear 57. The two locking members 51 are connected by transmission belts 58 arranged on the surfaces of the two third gears 57. The turntable 55 is fixedly connected to the first gear 52 in one of the locking members 51. Holes are penetrated at the top and bottom of the locking box 50 to adapt to the shape of the output end of the cylinder 3. Because the rotation directions of the two second gears 53 are opposite when the first gear 52 drives the two second gears 53, the spiral directions of the two second gears 53 are designed in opposite directions.

[0025] The staff rotates the turntable 55 clockwise or counterclockwise to drive the transmission rod 56, and the transmission rod 56 drives the first gear 52 and the third gear 57. At this time, the third gear 57 inside the two locking members 51 is driven by the transmission belt 58 to achieve synchronous rotation, and then the two first gears 52 drive the four second gears 53 to rotate, and the four second gears 53 drive the rotating column 54 to realize the removal and fixation of the bolt 4, thereby realizing the rapid removal of the cylinder 3 and meeting the needs of the staff.

[0026] like Figure 4-Figure 5 The easy-to-maintain printed scratch-resistant clamp shown in the figure comprises a fixing mechanism 6 which comprises a fixing column 60 fixedly connected to the top end of a pressing plate 7, a second spring 61 is provided on the right side of the inner wall of the fixing column 60, a movable plate 62 is fixedly connected to the other end of the second spring 61, an embedded column 63 is fixedly connected to the end of the movable plate 62 away from the second spring 61, movable blocks 64 are fixedly connected to the front and rear sides of the movable plate 62, and the ends of the two movable blocks 64 away from the movable plate 62 are fixedly connected to a push rod 65, and the ends of the push rod 65 away from the movable blocks 64 pass through the fixing column 60 and extend to the outside, the movable plate 62, the movable block 64 and the push rod 65 are all slidably connected to the inner wall of the fixing column 60, the output end of the cylinder 3 is provided with a hole groove corresponding to the embedded column 63 and the embedded column 63 is slidably connected to the hole groove, and in the initial state where the equipment is not disassembled, the embedded column 63 is slidably connected to the inside of the output end of the cylinder 3.

[0027] The staff pushes the push rod 65 to move away from the output end of the cylinder 3. At this time, the push rod 65 drives the movable plate 62 to move through the movable block 64, and the movable plate 62 drives the embedded column 63 to move away from the output end of the cylinder 3. When the embedded column 63 completely leaves the output end of the cylinder 3 and enters the inside of the fixed column 60, the embedded column 63 releases the fixation of the output end of the cylinder 3 and the pressure plate 7. Its structure is simple and fast. At the same time, during the operation of the equipment, the output of the cylinder 3 drives the pressure plate 7 to move downward and press on the printed matter. In this design, the size of the pressure plate 7 is the same as that of the support frame 2, so the overall force pressing of the printed matter can be achieved, thereby achieving seamless pressing of the printed matter.

[0028] Working principle of the utility model: when the cylinder 3 needs to be repaired, the staff drives the transmission rod 56 by rotating the turntable 55 clockwise or counterclockwise, and the transmission rod 56 drives the first gear 52 and the third gear 57. At this time, the third gear 57 inside the two locking members 51 is driven by the transmission belt 58 to realize synchronous rotation, so that the two first gears 52 drive the four second gears 53 to rotate, and the four second gears 53 drive the rotating column 54 to realize the removal and fixation of the bolt 4, thereby realizing the rapid removal of the cylinder 3 and meeting the needs of the staff. Then the staff pushes the push rod 65 away from the cylinder 3 , and moves toward the output end. At this time, the push rod 65 drives the movable plate 62 to move through the movable block 64, and the movable plate 62 drives the embedded column 63 to move away from the output end of the cylinder 3. When the embedded column 63 completely leaves the output end of the cylinder 3 and enters the inside of the fixed column 60, the embedded column 63 releases the fixation of the output end of the cylinder 3 and the pressing plate 7. At this time, the cylinder 3 can be moved away from the equipment. At the same time, during the operation of the equipment, the output of the cylinder 3 drives the pressing plate 7 to move downward and press on the printed matter. In this design, the size of the pressing plate 7 is the same as that of the support frame 2, so the overall force pressing of the printed matter can be achieved, thereby achieving seamless pressing of the printed matter.
