Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a book page trimming mechanism for book printing. Background Technology

[0002] In the printing industry, a de-edge machine (also known as a slitting machine, edge trimming machine, or waste edge removal machine) is a device used to trim or remove excess edges from printed materials. It is commonly used in post-printing processing to improve the appearance and functionality of the finished product. Most de-edge machines consist of a worktable and a cutting blade. The cutting blade is fixed to the blade holder by multiple fixing bolts. The printed material to be de-edged is placed on the worktable and fixed in the limit position. Then, the hydraulic press is started to move the cutting blade downward. After moving downward a certain distance, it contacts the printed material and performs the trimming.

[0003] However, this traditional edge trimming machine has the following drawbacks in actual use: 1. Low blade changing efficiency: Due to the different materials of the paper to be trimmed, different types of blades are required. The blade angle and material hardness must be matched to avoid chipping or incomplete cutting that leads to burrs. However, existing equipment requires manual disassembly of multiple fastening bolts (usually taking 5-10 minutes) to replace blades. The operation is cumbersome, time-consuming, and labor-intensive. The operation relies on professional technicians and cannot meet the demand for quick changeover in flexible production, thus reducing production efficiency. 2. Increased maintenance costs: After the blades wear out, the entire blade holder assembly needs to be replaced. However, the traditional integrated design means that the entire mechanism needs to be scrapped if a single blade is damaged. Industry reports indicate that the maintenance costs related to blades in traditional edge trimming machines account for 18%-25% of the total production cost. Utility Model Content

[0004] In view of the above situation and in order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a book page trimming mechanism for book printing, which effectively solves the problem of inconvenient tool replacement in existing trimming machines.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Depend on Figures 1 to 6 The device includes a support platform 1, with support columns 2 on the left and right sides of the upper end of the support platform 1, which are respectively arranged in the upper and lower axes. A support plate 3 is provided on the upper end of the two support columns 2. A tool holder 4 that can move up and down is slidably connected to the two support columns 2. A sliding groove 5 is opened at the front end of the tool holder 4, and the left end of the sliding groove 5 passes through the tool holder 4. A slider 6 is slidably connected in the sliding groove 5. A tool 7 is provided at the lower end of the slider 6. Multiple limiting grooves 8 are evenly distributed in the left and right directions at the rear end of the slider 6. Multiple limiting blocks 9 are provided in the tool holder 4, which correspond one-to-one with the limiting grooves 8 and can move back and forth. The left end face of the limiting block 9 is an inclined surface and can be inserted into the limiting groove 8.

[0025] In order to enable the tool holder 4 to move up and down, the upper end of the support plate 3 is provided with a hydraulic module 10, and the output end of the hydraulic module 10 is fixedly connected to the tool holder 4.

[0026] To facilitate the forward and backward movement of multiple limiting blocks 9, a clearance groove 11 is provided in the tool holder 4. A movable plate 12 located in the clearance groove 11 and capable of moving forward and backward is provided at the rear end of the multiple limiting blocks 9. The rear end of the movable plate 12 is connected to the tool holder 4 via multiple springs 13.

[0027] To facilitate the movement of the movable plate 12, a movable groove 14 is provided at the upper end of the tool holder 4, and a push plate 15 fixed to the movable plate 12 is slidably connected in the movable groove 14.

[0028] To facilitate the removal of slider 6, a pull ring is provided at the left end of slider 6.

[0029] For ease of use, the left end face of the limiting block 9 is inclined and can be inserted into the limiting groove 8.

[0030] To facilitate support, the lower end of the support platform 1 is provided with multiple pillars.

[0031] When using this utility model, first stack the paper to be cut and fix it on the support platform 1. Then, align the side to be cut with the cutter 7 vertically. At this time, start the hydraulic module 10. The output end of the hydraulic module 10 drives the cutter holder 4 to move downward. The cutter holder 4 drives the cutter 7 to move downward. After the cutter 7 moves downward a certain distance, it contacts the paper and cuts it off. After the cutting is completed, the hydraulic module 10 restarts and drives the cutter holder 4 and the cutter 7 on it to move upward. After moving a certain distance, it returns to the initial position.

[0032] When different materials need to be cut, the cutting tool 7 needs to be replaced. Push the push plate 15 backward. The push plate 15 drives the moving plate 12 to move backward. The moving plate 12 drives multiple limit blocks 9 to move backward. After the limit blocks 9 move backward a certain distance, they are pulled out from the corresponding limit groove 8, releasing the fixed limit on the slider 6. At this time, pull the pull ring to pull the slider 6 out from the sliding groove 5. Then, insert the slider 6 on the required cutting tool 7 into the sliding groove 5. Since the left end face of the limit block 9 is inclined, when the slider 6 moves to the right in the sliding groove 5, it squeezes the inclined surface of the limit block 9 and drives the limit block 9 to move backward, which in turn drives the moving plate 12 to move backward and squeeze the spring 13.

[0033] When the slider 6 is fully inserted into the sliding groove 5, the multiple limit blocks 9 correspond to the front and rear positions of the multiple limit grooves 8. Due to the restoring force of the spring 13, the moving plate 12 is driven to move forward. The moving plate 12 drives the multiple limit blocks 9 to move forward. After moving forward a certain distance, they are inserted into the corresponding limit grooves 8 to achieve fixed positioning, thereby realizing the quick replacement of the tool 7.

[0034] Compared with the prior art, the beneficial effects of this utility model are as follows: It is equipped with a support plate, a cutting tool, a hydraulic module, etc., which can realize the edge removal operation of printing paper. At the same time, it can quickly and conveniently replace different types of cutting tools when needed. The cooperation of multiple limiting blocks and limiting grooves can quickly fix and lock the cutting tool and the cutting tool holder. Compared with the traditional bolt fixing, the operation is simple, time-saving and labor-saving. Non-professional technicians can operate it, which improves production efficiency and reduces maintenance costs. This structure is simple, novel in concept, easy to use and highly practical.

[0035] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
