Description
Technical Field
[0001] This utility model relates to the field of punching equipment, specifically a punching device for producing scratch art books. Background Technology
[0002] In the production process of scratch art books, the punching process is a crucial step in enabling binding and page turning. Traditional scratch art book punching equipment suffers from the following technical challenges in practical applications:
[0003] I. Limitations of Existing Technology
[0004] Insufficient workpiece fixation stability: Traditional punching equipment often uses manual pressing or simple mechanical clamps to fix the scraping book. During the punching process, the workpiece is prone to displacement, which can lead to hole position deviation. Especially when the scraping book is of uneven thickness or is produced in batches, it is difficult to guarantee the consistency of hole position, which affects the subsequent binding accuracy.
[0005] The low efficiency of punch head replacement is a problem. To meet the punching requirements of different sizes of scratch art books (such as differences in hole diameter and number of holes), punch heads need to be replaced frequently. Existing equipment mostly uses bolts or welding to fix the punch heads, which requires tools to disassemble during replacement, is time-consuming and laborious, and is prone to coaxiality deviation due to installation errors, affecting the punching quality. Therefore, we have proposed a punching device for scratch art book production. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a punching device for producing scratch-off notebooks, which solves the aforementioned problems.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a punching device for producing scratch-off notebooks, characterized in that it includes a base, a connecting rod is fixedly installed on the top of the base, a drive cylinder is fixedly installed on the top end of the connecting rod, the output shaft of the drive cylinder passes through the top rod, a detachable punching head is provided at the lower end of the output shaft of the drive cylinder, and a pressing component is provided on the top of the base corresponding to the position of the punching head.
[0008] Preferably, the pressing assembly includes a concave mounting frame, a fixing cylinder, a middle horizontal plate, and a pressing plate. The concave mounting frame is fixedly mounted on the top of the top rod. A fixing cylinder is fixedly mounted on the surface of the top rod at the position corresponding to the concave mounting frame. A middle horizontal plate is fixedly mounted on the inner side of the concave mounting frame. The output shaft of the fixing cylinder passes through the middle horizontal plate. A pressing plate is fixedly mounted on the output shaft of the fixing cylinder. Both the concave mounting frame and the pressing plate have circular holes, and the positions of the circular holes correspond vertically to the positions of the punching heads.
[0009] Preferably, a connecting rod two is fixedly installed on the output shaft of the drive cylinder, and the connecting rod two is connected to the drilling head through a locking assembly.
[0010] Preferably, the punch head has an integrally formed central protrusion at one end of the connecting rod 2, and the connecting rod 2 has a central notch at the position corresponding to the central protrusion, and the central notch is inserted into the connecting rod 2.
[0011] Preferably, the connecting rod has a notch at one end and a rectangular opening on the central protrusion, and the locking assembly's insertion end is inserted into the rectangular opening.
[0012] Preferably, the locking assembly includes two locking plates, each with an arc-shaped notch in the middle. One locking plate has a rectangular insertion slot, and the other locking plate has an integrally formed rectangular pin. The rectangular pin passes through the rectangular opening and is inserted into the rectangular insertion slot. The two locking plates are connected together by a locking bolt threaded together.
[0013] Compared with the prior art, this utility model provides a punching device for producing scratch-off notebooks, which has the following beneficial effects:
[0014] I. Improve workpiece fixing accuracy and stability
[0015] The pneumatic pressing assembly design uses a fixed cylinder to drive the pressing plate and the concave mounting frame to form a clamping structure, achieving automatic positioning and clamping of the scratch art book. Compared to the traditional manual pressing method, this structure eliminates displacement errors caused by manual operation, keeping the hole position deviation within ±0.3mm. It is especially suitable for batch punching of multi-page scratch art books, ensuring hole position consistency and providing a precise foundation for subsequent binding processes.
[0016] II. Significantly improve the efficiency of punch head replacement
[0017] Employing a plug-in connection between a central protrusion and a central notch, combined with a quick-locking structure consisting of a clamping plate, rectangular pins, and locking bolts, the punch head can be replaced without tools. Actual test data shows that the replacement time is reduced from 10-15 minutes with traditional equipment to 2-3 minutes, and the coaxiality error of the replaced punch head is ≤0.1mm. This meets the need for rapid switching between different hole diameters (such as 3mm, 5mm, and 8mm) and hole counts, significantly improving the equipment's adaptability to various sizes of scratch art books.
[0018] III. Optimizing the cycle time and efficiency of automated production
[0019] The linkage control between the drive cylinder and the pressing component enables full automation of the "automatic clamping-drilling-resetting" process, reducing manual intervention. Production verification shows that the single-station drilling efficiency of this equipment can reach 60-80 times / minute, more than 40% higher than traditional semi-automatic equipment. Furthermore, it eliminates the need for complex additional feeding mechanisms, offering both efficiency and cost advantages in small-batch production.
[0020] IV. Reduce equipment maintenance costs and failure rate
[0021] The modular design separates the drive mechanism from the pressing assembly, allowing for independent replacement of worn parts (such as replacing the fixed cylinder or pressing plate separately), reducing maintenance costs by 60% compared to traditional integrated structures. Meanwhile, the detachable connection between the punch head and the connecting rod avoids loosening issues caused by long-term impact. After 5000 consecutive tests, no significant displacement was observed in key connection points, significantly improving the equipment's operational stability. Attached Figure Description
