Description

Technical Field

[0001] This utility model relates to the field of book cutting technology, and more specifically, to a die-cutting device for book production. Background Technology

[0002] Die-cutting equipment plays a crucial role in the book printing process. Traditional die-cutting equipment typically has three blades that simultaneously cut three sides of the book. However, this design has some problems: a tiny gap inevitably exists between adjacent blades. Despite the small gap, during the cutting process, the paper may not be cut precisely at the corresponding gap, which not only reduces cutting efficiency but also affects the cutting effect and the quality of the final product.

[0003] Furthermore, traditional die-cutting equipment lacks flexibility and adaptability when dealing with paper of different materials and thicknesses. Fixed cutting parameters fail to meet diverse needs, leading to quality problems such as burrs, tears, or dimensional deviations at the cut edges, severely impacting product yield. Meanwhile, manually adjusting cutting parameters is inefficient and inaccurate, increasing production and time costs.

[0004] To address the aforementioned problems, this application proposes a die-cutting device for book production that facilitates cutting. This device aims to improve cutting efficiency and quality, reduce production costs, and meet the modern book printing industry's demand for efficient and precise die-cutting equipment. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a die-cutting device for book production to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting device for book production, comprising a worktable, a cutter, a rotating assembly, and a lifting assembly. The cutter is mounted on the rotating assembly for cutting paper. The rotating assembly is mounted below the lifting assembly for driving the cutter to rotate to correspond to the three sides of the paper, so that the cutter cuts the three sides of the paper. The lifting assembly is mounted on the worktable for driving the rotating assembly and the cutter to move up and down, thereby achieving the cutting of the paper by the cutter.

[0007] By adopting the above technical solution, the same cutter cuts the three sides of the paper separately. Each cut completely severs the paper and divides it into two pieces. Therefore, it can effectively avoid the phenomenon of incomplete cutting caused by gaps between the cutters when multiple cutters are used.

[0008] The present invention is further provided with a pad for placing paper on the workbench, a baffle for limiting the paper is fixed on one side of the pad, and several knife grooves are opened on the pad to prevent the cutter from hitting the pad when cutting the paper, thus preventing damage to the cutter blade.

[0009] The present invention is further configured such that the rotating component includes a first drive motor and a mounting plate, the first drive motor is mounted on the lifting component, and the output shaft of the first drive motor passes through the lifting component and is connected to the mounting plate, and the cutter is fixed to the lower surface of the mounting plate.

[0010] The present invention is further configured such that the lifting assembly includes a support frame, a drive cylinder, and a lifting plate. The support frame is fixed to the upper surface of the workbench, the drive cylinder is fixed to the upper surface of the support frame, and the telescopic end of the drive cylinder passes through the support frame and is connected to the lifting plate. A guide rod for limiting the movement path of the lifting plate is installed on the lifting plate, and the guide rod slides through the support frame, so that the lifting plate can only move up and down along the telescopic direction of the drive cylinder. A first drive motor is installed on the lifting plate, and the output shaft of the first drive motor passes through the lifting plate and is connected to the mounting plate.

[0011] The present invention is further configured such that a limiting block is provided above the mounting plate, a connecting rod is provided between the limiting block and the mounting plate for connecting the two, and a limiting frame is provided on the lower surface of the lifting plate for limiting the vertical movement of the limiting block but not limiting its horizontal movement. A first clearance groove is provided on the limiting frame for the connecting rod to pass through and move.

[0012] The present invention is further configured such that a pressure plate assembly for pressing and positioning paper is installed on the worktable. The pressure plate assembly includes a longitudinal moving assembly, a pressing plate, and a connecting plate for connecting the two. A second clearance groove is provided on the baffle for the connecting plate to pass through and move up and down. The pressing plate is located above the pad and below the lifting assembly and the rotating assembly, and is used to press and fix the paper from above, so as to facilitate the cutter to cut the paper.

[0013] The present invention is further configured such that the longitudinal moving component includes a second drive motor, a lead screw, a moving block, and a mounting frame. The lead screw is longitudinally mounted on the mounting frame, and both ends of the lead screw are rotatably connected to the mounting frame. The second drive motor is fixed to the top of the mounting frame, and its output shaft is connected to the lead screw. The moving block is threaded onto the outside of the lead screw, and the moving block is slidably connected to the mounting frame. The moving block can move longitudinally.

[0023] In practical applications, the prepared paper is placed on the pad 5 and attached to the baffle 6. The pressure plate assembly 7 is activated to press and fix the paper. Then, the rotating assembly 3 is activated so that the cutter 2 is aligned with the top of the wide side of the paper. The lifting assembly 4 is activated so that the cutter 2 moves downward to cut the paper. After cutting, the lifting assembly 4 moves the cutter 2 upward away from the paper area. The rotating assembly 3 is activated again so that the cutter 2 is aligned with the long side of the paper. The lifting assembly 4 is activated so that the cutter 2 moves downward to cut. The above operation is repeated to cut the bottom of the wide side of the paper, thereby achieving three-sided cutting of the paper.

[0024] In actual operation, it is important to note that the length of the pad 5 should be less than the length of the paper after cutting, so as to avoid interference between the cutter 2 and the pad 5 when cutting the wide edge of the paper.

[0025] In this embodiment, a pressure plate assembly 7 for pressing and positioning paper is installed on the workbench 1. The pressure plate assembly 7 includes a longitudinal moving assembly 701, a pressing plate 702, and a connecting plate 703 for connecting the two. A second clearance groove 601 is provided on the baffle 6 for the connecting plate 703 to pass through and move up and down. The pressing plate 702 is located above the pad 5 and below the lifting assembly 4 and the rotating assembly 3, and is used to press and fix the paper from above, so as to facilitate the cutter 2 to cut the paper. The longitudinal moving assembly 701 includes a second drive motor 701. 1. A lead screw 7012, a movable block 7013, and a mounting bracket 7014. The lead screw 7012 is longitudinally mounted on the mounting bracket 7014, and both ends of the lead screw 7012 are rotatably connected to the mounting bracket 7014. The second drive motor 7011 is fixed to the top of the mounting bracket 7014, and its output shaft is connected to the lead screw 7012. The movable block 7013 is threaded onto the outside of the lead screw 7012, and the movable block 7013 is slidably connected to the mounting bracket 7014. The movable block 7013 can move longitudinally. The connecting plate 703 is fixedly connected to the movable block 7013.

[0026] When the paper is pressed and fixed, the second drive motor 7011 is started, which drives the lead screw 7012 to rotate, thereby driving the moving block 7013 to move downward. Through the connecting plate 703, the pressing plate 702 moves downward together until it contacts the upper surface of the paper and applies a certain pressure to the paper to fix it.
