Description

Technical Field

[0001] This utility model relates to the field of printed material cutting technology, specifically to an automatic cutting device for printed books and periodicals. Background Technology

[0002] Printed materials are generally divided into books, periodicals, and magazines, which are commonly used paper reading products. In order to ensure that the paper width is sufficient to support the page width during the printing process, the paper width selected during printing is larger than the page width. After the subsequent binding work is completed, in order to ensure the aesthetics of the books and periodicals, it is often necessary to cut off the excess blank corners at the edges of the books and periodicals.

[0003] Currently, printed materials are usually cut by stacking multiple layers together. When the printed materials are automatically conveyed to the cutting blade, they may become loose, requiring workers to stack them neatly, which is not only dangerous but also results in low cutting efficiency. Furthermore, the cutting blade is cut without support, which can easily lead to cutting errors or damage to the conveyor belt. Therefore, there is an urgent need to design an automatic cutting device for printed materials to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cutting device for printed books and periodicals to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic cutting device for printed books and periodicals includes a processing table, a support frame installed on the bottom side of the processing table, two conveying mechanisms arranged symmetrically inside the processing table, a fixed frame installed in the middle of the top side of the processing table, a cylinder installed on the top of the fixed frame, a lifting plate installed through the output end of the cylinder through the fixed frame, and a cutting blade installed at the bottom of the lifting plate. The processing table has two sliding limit plates, which are located between the two conveying mechanisms. An adjustment mechanism is provided between the two limit plates. The processing table has two limit rollers that are rotatably engaged with and slidingly engaged with the two limit plates. Each end of the limit plate is provided with a pressing mechanism. The processing table has a support plate that is slidably engaged with the cutting blade. A transmission mechanism is provided between the lifting plate and the support plate.

[0006] Furthermore, the conveying mechanism includes two conveying rollers rotatably fitted inside the processing table and a conveyor belt sleeved around the two conveying rollers. A first motor is installed on one side of the processing table, and pulleys are provided at one end of the two conveying rollers located in the middle. A synchronous belt is sleeved around the two pulleys, and the output end of the first motor is connected to one end of one of the conveying rollers.

[0007] Furthermore, the adjustment mechanism includes a second motor installed on one side of the processing table and a bidirectional lead screw rotatably engaged within the processing table. The output end of the second motor is connected to one end of the bidirectional lead screw. The bidirectional lead screw is threadedly engaged with two limiting plates. The top of the limiting plates has a groove corresponding to the support plate, and a sensor is provided on the top of the limiting plates.

[0008] Furthermore, the extrusion mechanism includes a pressure plate rotatably fitted to one end of the limiting plate, and a push plate slidably fitted and rotatably fitted within the limiting plate. A torsion spring is provided between the middle of the pressure plate and the limiting plate. A limiting groove is provided on the push plate, and a limiting rod is provided within the limiting plate. The limiting groove and the limiting rod are slidably fitted and rotatably fitted. One end of the push plate is rotatably fitted with one end of the pressure plate.

[0009] Furthermore, the transmission mechanism includes two gears that are rotatably fitted inside the inner wall of the fixed frame, two first toothed plates that are respectively disposed at both ends of the lifting plate, and two second toothed plates that are respectively disposed at both ends of the support plate, wherein the two sides of the gears mesh with the first toothed plates and the second toothed plates respectively.

[0010] Furthermore, the bottom of the lifting plate is provided with an installation frame, and a fixing bolt that cooperates with the cutting blade is provided in the installation frame. The top of the support plate is provided with a cutting groove corresponding to the cutting blade.

[0011] The automatic cutting device for printed books and periodicals provided by this utility model, as described above, has the following advantages: The adjustable mechanism allows two limiting plates to flatten and squeeze both sides of the printed materials. The two squeezing mechanisms at both ends of the limiting plates then flatten and squeeze both ends of the printed materials, automatically stacking them neatly under the cutting blade. This facilitates flat cutting, improving efficiency and reducing the dangers of manual stacking. The transmission mechanism, when the cylinder drives the lifting plate to cut downwards, moves the support plate upwards, supporting the bottom of the printed materials. This ensures stable cutting, reduces damage to the conveying mechanism, and does not disrupt normal transport. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown in the figure, this utility model provides an automatic cutting device for printed books and periodicals.

[0020] The system includes a processing table 1, a support frame 2 installed on the bottom side of the processing table 1, two conveying mechanisms 3 installed inside the processing table 1, the two conveying mechanisms 3 being symmetrically distributed, a fixed frame 4 installed in the middle of the top side of the processing table 1, a cylinder 5 installed on the top of the fixed frame 4, a lifting plate 6 installed at the output end of the cylinder 5 passing through the fixed frame 4, and a cutting blade 7 installed at the bottom of the lifting plate 6. The processing table 1 has two sliding limit plates 8, which are located between two conveying mechanisms 3. An adjustment mechanism 9 is provided between the two limit plates 8. The processing table 1 has two limit rollers 10 that are slidably and rotatably engaged with the two limit plates 8. Both ends of the limit plates 8 are provided with extrusion mechanisms 11. The processing table 1 has a support plate 12 that is slidably engaged with the cutting blade 7. A transmission mechanism 13 is provided between the lifting plate 6 and the support plate 12.

[0021] Reference Figure 2 In this embodiment, the conveying mechanism 3 includes two conveying rollers 14 rotatably fitted within the processing table 1 and a conveyor belt 15 sleeved around the two conveying rollers 14. A first motor 16 is mounted on one side of the processing table 1. Each of the two conveying rollers 14 located in the middle is provided with a pulley 17 at one end, and a synchronous belt 18 is sleeved around the two pulleys 17. The output end of the first motor 16 is connected to one end of one of the conveying rollers 14. Through the first motor 16, one of the conveying rollers 14 can be driven, causing the conveying roller 14 to drive the other conveying roller 14 to rotate via the conveyor belt 15, allowing the conveyor belt 15 to convey the printed material. The two conveying rollers 14 in the middle can be driven by the pulleys 17 and the synchronous belt 18, enabling the two conveying mechanisms 3 to convey simultaneously.

[0022] Reference Figure 3 The adjustment mechanism 9 in this embodiment includes a second motor 19 mounted on one side of the processing table 1 and a bidirectional lead screw 20 rotatably fitted inside the processing table 1. The output end of the second motor 19 is connected to one end of the bidirectional lead screw 20. The bidirectional lead screw 20 is threadedly fitted with two limiting plates 8. The top of the limiting plates 8 has a groove 21 corresponding to the support plate 12, and a sensor 22 is provided on the top of the limiting plates 8. By using the bidirectional lead screw 20, the second motor 19 can be started to drive the bidirectional lead screw 20 to rotate, causing the bidirectional lead screw 20 to drive the two limiting plates 8 to move towards each other, allowing the two limiting plates 8 to push and squeeze the sides of the printed material, thus flattening the sides of the printed material.

[0023] Reference Figure 3The extrusion mechanism 11 in this embodiment includes a pressure plate 23 rotatably fitted to one end of a limiting plate 8, and a push plate 24 slidably fitted and rotatably fitted within the limiting plate 8. A torsion spring 25 is provided between the middle of the pressure plate 23 and the limiting plate 8. A limiting groove 26 is provided on the push plate 24, and a limiting rod 27 is provided within the limiting plate 8. The limiting groove 26 and the limiting rod 27 are slidably fitted and rotatably fitted. One end of the push plate 24 is rotatably fitted with one end of the pressure plate 23. When the two limiting plates 8 extrude and flatten the two sides of the printed material through the pressure plate 23, the printed material pushes the push plate 24, causing the push plate 24 to move along the limiting rod 27. The push plate 24 then pushes the pressure plate 23 to rotate, causing the pressure plate 23 to extrude and flatten both ends of the printed material, thus completing the flattening and stacking of the printed material. After the two limiting plates 8 move away from each other, the torsion spring 25 can drive the pressure plate 23 to rotate and reset.

[0024] Reference Figure 4 The transmission mechanism 13 in this embodiment includes two gears 28 rotatably fitted on both sides of the inner wall of the fixed frame 4, two first toothed plates 29 respectively disposed at both ends of the lifting plate 6, and two second toothed plates 30 respectively disposed at both ends of the support plate 12. The two sides of the gears 28 mesh with the first toothed plates 29 and the second toothed plates 30 respectively. Through the gears 28, the cylinder 5 can drive the lifting plate 6 to move downward, causing the lifting plate 6 to drive the first toothed plates 29 to move downward. The first toothed plates 29 will drive the gears 28 to rotate, causing the gears 28 to drive the second toothed plates 30 to move upward. The second toothed plates 30 will drive the support plate 12 to move upward, allowing the support plate 12 to support the bottom of the printed material.

[0025] Reference Figure 4 In this embodiment, the bottom of the lifting plate 6 is provided with a mounting frame 31, and a fixing bolt 32 that cooperates with the cutting blade 7 is provided inside the mounting frame 31. The top of the support plate 12 is provided with a cutting groove 33 corresponding to the cutting blade 7. Through the mounting frame 31, the cutting blade 7 can be fixedly installed in the mounting frame 31 using the fixing bolt 32. The cutting blade 7 can be replaced as needed. After the cutting blade 7 cuts through the printed material, it will enter the cutting groove 33, avoiding rigid collision between the cutting blade 7 and the support plate 12.

[0026] Working principle: In use, the two conveying mechanisms 3 first cut the printed materials, moving them below the fixed frame 4. At this time, the sensor 22 on the limit plate 8 detects the printed materials to be cut and activates the adjusting mechanism 9, causing the two limit plates 8 to move towards each other. The two limit plates 8 push and squeeze the two sides of the printed materials respectively. At the same time, the two squeezing mechanisms 11 at both ends of the limit plates 8 push and squeeze the two ends of the printed materials, arranging them neatly. Then, the limit plates 8 continue to fix the printed materials. Meanwhile, the cylinder 5 drives the lifting plate 6 to move downward, causing the lifting plate 6 to move the cutting blade 7 downward. While the lifting plate 6 moves downward, the transmission mechanism 13 is activated, causing the transmission mechanism 13 to move the support plate 12 upward, allowing the support plate 12 to support the bottom of the printed materials. The cutting blade 7 cuts the printed materials. After cutting, all components are reset, and the limit plate 8 assists the conveying mechanism 3 in conveying the cut printed materials.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
