Description

Technical Field

[0001] This utility model relates to binding equipment, and more particularly to an adjustable hydraulic punching device for bookbinding. Background Technology

[0002] Currently, large-scale binding equipment is mostly used for punching and binding large quantities of books. However, for binding small quantities of books, such as textbooks, test compilations, promotional materials, and product manuals compiled by schools, government agencies, or enterprises, small, simple binding and punching equipment is often used for manual punching and binding. However, these binding and punching equipment usually have fixed hole spacing and fixed binding distance between the hole and the edge of the book, which cannot be adjusted. Since the paper specifications of textbooks, test compilations, promotional materials, and product manuals bound by different organizations are mostly different, the hole spacing and position required for punching are mostly different. Therefore, the current binding and punching methods cannot adapt to the binding and punching of small quantities of small quantities of books with different paper specifications. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a small, adjustable hydraulic punching device for bookbinding that can adapt to different types of paper for binding and punching.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an adjustable hydraulic punching device for bookbinding, including a platform with supporting feet at the bottom, a crossbeam above the platform, columns between the two ends of the crossbeam and the platform, a groove at the bottom of the crossbeam, a slider slidably disposed in the groove, a cylinder mounted at the bottom of the slider, a punch mounted at the piston rod end of the cylinder, the cylinder connected to a high-pressure oil source, a row of punches for cooperating with the punches arranged below the groove on the platform, a punching positioning device for aligning the punches with each punch between the crossbeam and the slider; a pressure plate slidably disposed between the two columns below the cylinder, the pressure plate having a slot for the punches to pass through, a pressing drive device for driving the pressure plate to rise and fall on the platform; and binding alignment devices and edge trimming devices respectively disposed on both sides of the arranged punches on the platform.

[0005] As a preferred technical solution, the end of the cylinder piston rod is also connected to a pressure block by a spring. The pressure block is provided with a pin hole, and the punch slides through the pin hole. The pressure plate is provided with constraint holes corresponding to each punch hole, which slide and cooperate with the pressure block.

[0006] As a preferred technical solution, the punching positioning device includes positioning holes arranged on a crossbeam that correspond one-to-one with each punch hole, the inner end of each positioning hole being connected to a sliding groove, a positioning pin with a hemispherical inner end being slidably disposed in the positioning hole, a positioning groove corresponding to the shape of the inner end of the positioning pin being disposed on the slider, and a positioning spring being disposed on the crossbeam to drive the inner end of the positioning pin into the sliding groove.

[0007] As a preferred technical solution, the binding alignment device includes an alignment plate slidably disposed on a table, the alignment plate being arranged parallel to the arranged punches, and an alignment driving device being disposed between the alignment plate and the table.

[0008] As a preferred technical solution, a positioning screw is provided in the slide groove, the slider is threadedly fitted on the positioning screw, the two ends of the positioning screw are rotatably mounted on the crossbeam, a handwheel is provided at the end of the positioning screw, and a transition slope is provided between the surface of the slider near the positioning pin and the two end faces.

[0009] As a preferred technical solution, the edge-trimming device includes two guide plates arranged opposite to each other on a platform. The two guide plates are arranged perpendicularly to each other with the arranged punch holes. The platform has guide grooves that are parallel to the arranged punch holes at the guide plates. The bottom of the two platforms is provided with movable seats that extend through the guide grooves and out of the bottom of the platform.

[0010] This adjustable hydraulic bookbinding punching device, employing the aforementioned technical solution, aligns the punches with each hole through the sliding of the slider and the positioning of the punching device. It allows for selection of the punch and corresponding hole alignment based on the hole spacing required for different sizes and models of book paper. The hole spacing is easily adjustable. Simultaneously, a pressing drive device drives the pressure plate to rise and fall, pressing the punched areas of the book paper firmly to prevent warping and bending during punching, ensuring smooth punching. The binding alignment device adjusts the binding distance between the holes and the book's edge.

Detailed Implementation

[0013] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present invention are illustrated.

[0014] like Figure 1-3As shown, the adjustable hydraulic punching device for bookbinding includes a platform 2 with support feet 1 at the bottom, a crossbeam 3 above the platform 2, columns 4 between the two ends of the crossbeam 3 and the platform 2, a groove 5 at the bottom of the crossbeam 3, a slider 6 slidingly mounted in the groove 5, a cylinder 7 mounted at the bottom of the slider 6, a punch 9 mounted at the piston rod end of the cylinder 7, and a high-pressure oil source connected to the cylinder 7. The high-pressure oil source can be selected from small hydraulic systems such as miniature hydraulic stations with hydraulic control systems, depending on the punching environment and the needs of bookbinding, making it more convenient to use; the platform 2 is located below the groove 5 A row of punches 10 are arranged in a square arrangement to cooperate with the punches 9. A punching positioning device is provided between the crossbeam 3 and the slider 6 for aligning the punches 9 with each punch 10 for punching. A pressure plate 11 is slidably arranged between the two columns 4 below the oil cylinder 7. The pressure plate 11 is provided with a slot 12 for the punches 9 to pass through. The slot 12 ensures that the book paper is pressed tightly at the punches 10 of the pressure plate 11 while reducing the obstruction to the movement of the punches 9. A pressing drive device is provided on the table 2 to drive the pressure plate 11 to rise and fall. A binding alignment device and an edge trimming device are also provided on both sides of the arranged punches 10 on the table 2. Since this utility model is a small, adjustable hydraulic punching device for bookbinding, it can be placed on a suitable flat surface such as a desktop using the support foot 1. The slide groove 5 and the slider 6 can be fitted with a T-shaped groove and a T-shaped slider to improve the stability of the slider 6 sliding, the movement of the cylinder 7 and the punch 9, and the punching. Furthermore, the T-shaped slider and the cylinder 7 can be connected and extended to both sides along the bottom of the crossbeam 3 to further improve the stability of the slider 6 sliding. The binding alignment device adjusts the binding distance between the hole and the edge of the book according to the different specifications and binding requirements of the book paper. The edge trimming device makes the edges of the paper neater when the book paper is placed in the punching position.

[0015] like Figure 1 , 2 As shown in Figure 4, the end of the piston rod of the hydraulic cylinder 7 is also connected to a pressure block 13 via a spring. The pressure block 13 is provided with a pin hole, through which the punch 9 slides. The pressure plate 11 is provided with constraint holes 14 corresponding to each punch hole 10, which slide and cooperate with the pressure block 13. The constraint holes 14 are located on the strip hole 12 and communicate with the strip hole 12. When punching, the piston rod extends downward, the punch 9 moves downward, and the spring and pressure block 13 move downward synchronously. The punch 9 contacts the paper of the book and begins to punch. At the same time, the pressure block 13 begins to press the paper around the punch 9. As the punch 9 continues to move downward, the pressure of the pressure block 13 on the paper increases under the action of the spring. While preventing the paper around the punch 9 from lifting, the pressure block 13 also plays a role in straightening and preventing the punch 9 from bending. This solves the problem of the punch guard easily bending when punching in the existing binding punching equipment, ensuring smooth punching operation 10. At the same time, the constraint holes 14 on the pressure plate 11 support and constrain the pressure block 13, preventing the pressure block 13 from shifting or tilting.

[0016] like Figure 1, 2 As shown in Figure 5, the punching positioning device includes a crossbeam 3 with positioning holes 15 arranged one-to-one with each punch 10. The inner end of each positioning hole 15 is connected to a slide groove 5. A positioning pin 16 with a hemispherical inner end is slidably disposed in the positioning hole 15. A positioning groove 17 corresponding to the shape of the inner end of the positioning pin 16 is provided on the slider 6. A positioning spring 18 is provided on the crossbeam 3 to drive the inner end of the positioning pin 16 into the slide groove 5. Thus, when the slider 6 slides to a punch 10 for punching, the inner end of the positioning pin 16 corresponding to the punch 10 is inserted into the positioning groove 17 under the action of the positioning spring 18, thereby aligning the punch 9 with the punch 10 for punching. A positioning screw 19 can be installed in the slide groove 5. The slider 6 is threaded onto the positioning screw 19. Both ends of the positioning screw 19 are rotatably mounted on the crossbeam 3. A handwheel 20 is provided at the end of the positioning screw 19. A transition slope 21 is provided between the surface of the slider 6 near the positioning pin 16 and the two end faces of the slider 6. In this way, the positioning screw 19 is rotated by the handwheel 20, which drives the slider 6 to move left and right, and drives the hydraulic cylinder 7 and the punch 9 to move left and right. When the slider 6 is close to a positioning pin 16, the transition slope on the slider 6 contacts the inner spherical surface of the positioning pin 16, pushing the positioning pin 16 outward. The slider 6 continues to move until the inner spherical surface slides into the positioning groove 17 and falls into the positioning groove 17 for positioning. At this time, the positions of the slider 6, hydraulic cylinder 7 and punch 9 are fixed, and drilling operations can be performed. When it is necessary to change the drilling position, simply pull the positioning pin 16 outward and rotate the handwheel 20 to drive the positioning screw 19 to rotate and move the slider 6. Alternatively, a hydraulic cylinder and an electric push rod can be installed between the crossbeam 3 and the slider 6 to push and pull the slider 6 to achieve movement.

[0017] like Figure 1-3 As shown, the binding alignment device includes an alignment plate 22 slidably mounted on a platform 2. The alignment plate 22 can be slidably mounted on the platform 2 via a slide rail 23. The alignment plate 22 is parallel to the arranged punches 10. An alignment drive device 24 is provided between the alignment plate 22 and the platform 2. The alignment drive device 24 drives the alignment plate 22 to move back and forth, moving it away from and closer to the punches 10, thereby adjusting the distance between the alignment plate 22 and the arranged punches 10, and adjusting the binding spacing between the holes punched on the book paper and the book edge to accommodate different book paper specifications and binding requirements. Alternatively, the binding alignment device can use insertion holes on the platform 2 with different spacing from the arranged punches 10. During binding, the alignment plate 22 is inserted into the corresponding insertion hole according to the paper specifications and binding requirements, resulting in a simple and practical structure.

[0018] like Figure 2 and 3As shown, the edge-aligning device includes two guide plates 25 arranged opposite each other on a platform 2. The two guide plates 25 are perpendicular to the arranged punch holes 10. Guide grooves 26, parallel to the arranged punch holes 10, are provided on the platform 2 at the guide plates 25. Movable seats 27, extending through the guide grooves 26 and extending from the bottom of the platform 2, are respectively provided on the bottom of the platform 2. An edge-aligning drive device is provided on the bottom of the platform 2 to drive the two movable seats 27 to move synchronously towards each other. The edge-aligning drive device drives the movable seats 27 to move the two guide plates 25 synchronously towards each other, accommodating binding and punching of different sizes and models of book paper. Simultaneously, the two guide plates 25 also help to neaten the edges of the paper when it is placed in the binding and punching position, making the edges of the paper more uniform. Alternatively, several insertion holes can be set on the platform 2 in a manner parallel to the arranged punch holes 10. During punching, the two guide plates 25 are inserted into the corresponding insertion holes according to the paper size and model. This structure is simple and practical.

[0019] As shown in 1, 2, and 3, the edge-following drive device can employ an edge-following screw 28 rotatably mounted at the bottom of the platform 2 below the guide groove 26. The edge-following screw 28 and the guide groove 26 are parallel to each other, and the threads on both sides of the edge-following screw 28 have opposite directions. Two movable seats 27 are respectively fitted onto both sides of the edge-following screw 28 via threaded engagement. The edge-following screw 28 is connected to a drive device such as a handwheel 20 or a motor. Alternatively, a hydraulic cylinder and an electric push rod can be installed between the platform 2 and the two movable seats 27 to push and pull the movable seats 27 to move the guide plate 25. The pressing drive device can be configured by simultaneously extending and retracting hydraulic cylinders or electric push rods between the two ends of the pressure plate 11 and the crossbeam 3 to drive the pressure plate 11 to rise and fall. Alternatively, the two ends of the pressure plate 11 can be threaded onto screws, with a drive shaft driven by a handwheel 20 or a motor rotatably mounted at the bottom of the platform 2. The bottoms of the two screws pass through the platform 2 and engage with the drive shaft via bevel gears to drive the pressure plate 11 to rise and fall. Vertical slide rails 8 are respectively provided on the inner sides of the two columns 4, and sliding columns extending into the vertical slide rails 8 are respectively provided at the two ends of the pressure plate 11 to constrain the rise and fall of the pressure plate 11. The alignment drive device 24 can be configured by setting hydraulic cylinders, electric push rods, or screw structures driven by handwheels or motors between the platform 2 and the alignment plate 22 to push and pull the alignment plate 22 to move the guide plate 25 away from or towards the arranged punches 10.

[0020] In this utility model, the hydraulic cylinder, electric push rod, and screw structure used in the alignment drive device 24, pressing drive device, and edge-aligning drive device are all known structures and drive methods. The alignment drive device 24, pressing drive device, and edge-aligning drive device can be manufactured with different drive structures and drive methods according to the needs of schools, government agencies, or enterprises, the drilling operation environment, or the size of this utility model, so as to better suit the needs of the bookbinding operation environment.

[0021] like Figure 1-3As shown, the use of this small, adjustable hydraulic bookbinding punching device is illustrated using a book with a large number of pages, such as a compilation of test questions. In use, the device is placed on a table using the support foot 1. First, according to the binding requirements of the test question compilation, the alignment drive device 24 controls the alignment plate 22 to move and adjust the distance between the alignment plate 22 and the punch 10. Then, the edge-aligning drive device controls the movement of the two guide plates 25 to make the distance between the two guide plates 25 suitable for the paper size of the prepared test question compilation. Next, the prepared test question compilation is placed between the two guide plates 25 and positioned between the lower side of the pressure plate 11 and the upper side of the punch 10, with the punched side of the test question compilation resting against the alignment plate 22. Then, the pressing drive device controls the pressure plate 11 to descend and press against the punched area on the test question compilation. Finally, the handwheel 20 controls the rotation of the positioning screw 19, driving the slider 6 to move within the groove 5 until it aligns with the punch 10 to be punched. At the corresponding positioning pin 16, the inner end of the positioning pin 16 falls into the positioning groove 17 under the action of the positioning spring 18 for positioning, so that the slider 6, the oil cylinder 7 and the punch 9 are fixed in position. The piston rod of the control oil cylinder 7 extends downward, the punch 9 moves downward, and drives the spring and the pressure block 13 to move downward synchronously. The pressure block 13 slides into the constraint hole 14 on the pressure plate 11. When the punch 9 contacts the test paper and starts to punch, the pressure block 13 presses the paper part around the punch 9. As the punch 9 continues to move downward to punch, the pressure block 13 on the paper part around the punch 9 under the action of the spring also increases, thereby preventing the paper around the punch from lifting and playing a role in straightening and protecting the punch 9, ensuring smooth punching operation. After punching 10 is completed, the piston rod of the control oil cylinder 7 retracts, the punch 9 moves upward, and drives the spring and the pressure block 13 to move upward back to their original position. Then, the positioning screw 19 is rotated by the handwheel 20 to drive the slider 6 to move in the slide groove 5 to perform the punching operation at the next position.
