Description

An automated punching device for packaging products Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a punching device for automated production of packaging products. Background Technology

[0002] Perforation is a common process in the production and processing of packaging products to achieve functional requirements such as ventilation, hanging, or securing. Automated perforation production equipment is widely used in the modern packaging industry, significantly improving production efficiency and product quality. However, existing automated perforation production equipment for packaging products has some significant drawbacks in practical applications, particularly in the automatic discharge of surplus material. These issues not only affect production efficiency but also increase maintenance costs and operational complexity.

[0003] Existing automated punching devices for packaging products perform poorly in handling scrap materials. During the punching process, scrap materials (such as waste paper and waste plastic sheets) accumulate inside the equipment if not discharged promptly, causing operational difficulties. These scrap materials not only occupy space within the punching device but may also become entangled in transmission components, affecting normal operation. For example, scrap material accumulating near the punching cutter may accelerate cutter wear or even jam the cutter, forcing the production line to stop for cleaning. Such downtime severely impacts production efficiency, increases equipment maintenance costs, and intensifies the workload for operators.

[0004] The inability to automatically discharge excess material can also lead to a decline in product quality. During the punching process, if excess material cannot be discharged in time, it may be re-rolled into the packaging material, causing irregular holes or blockages. This not only affects the appearance of the packaging but may also impact its functionality. For example, if ventilation holes are blocked by excess material, the product inside may spoil due to poor ventilation; if hanging holes are blocked, the packaging may not hang properly, affecting logistics and display. These problems directly impact the product's market competitiveness and customer satisfaction.

[0005] The inability to automatically discharge excess material increases the workload of operators. Existing punching devices typically require operators to manually clean up excess material periodically, which not only increases the labor intensity of operators but may also lead to frequent production line downtime. During manual cleaning, operators must also exercise extreme caution to avoid cuts from sharp blades or injuries from flying material. Furthermore, manual cleaning can cause secondary contamination of the equipment, affecting its cleanliness and hygiene.

[0006] The inability to automatically discharge excess material also limits the flexibility and adaptability of equipment. The modern packaging industry has increasingly higher demands for multi-variety, small-batch production, requiring production equipment to quickly switch between different production tasks. However, if the punching device cannot automatically discharge excess material, manual cleaning of excess material is necessary each time a production task is changed. This not only increases changeover time but may also lead to inaccurate equipment adjustments, affecting production efficiency and product quality.

[0007] Therefore, how to provide an automated punching device for packaging products is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] One objective of this invention is to provide an automated punching device for packaging products. This invention utilizes a hydraulic telescopic rod. The extension or retraction of the hydraulic telescopic rod moves a guide frame, which slides back and forth on the mounting frame. The end-sealing plate moves the punching cylinder and the fixing cylinder. The punching cylinder moves towards the packaging product to punch holes. The cutting edge at the front of the punching cylinder punches holes in the packaging product. The excess material cut from the packaging product squeezes the push ring, which moves the branch rod, which in turn moves the sliding rod. The sliding rod moves back and forth within the collar, and the push ring compresses the return spring. After punching, the excess material from the packaging product is pushed out of the punching cylinder by the push ring.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Existing automated punching devices for packaging products perform poorly in handling scrap materials. During the punching process, scrap materials (such as waste paper and waste plastic sheets) accumulate inside the equipment if not discharged promptly, causing operational difficulties. These scrap materials not only occupy space within the punching device but may also become entangled in transmission components, affecting normal operation. For example, scrap material accumulating near the punching cutter may accelerate cutter wear or even jam the cutter, forcing the production line to stop for cleaning. Such downtime severely impacts production efficiency, increases equipment maintenance costs, and intensifies the workload of operators.

[0026] The inability to automatically discharge excess material can lead to a decline in product quality. During the punching process, if excess material cannot be discharged in time, it may be re-rolled into the packaging material, causing irregular holes or blockages. This not only affects the appearance of the packaging but may also impact its functionality. For example, if ventilation holes are blocked by excess material, the product inside may spoil due to poor ventilation; if hanging holes are blocked, the packaging may not hang properly, affecting logistics and display. These issues directly impact a product's market competitiveness and customer satisfaction.

[0027] The inability to automatically discharge residual material also limits the flexibility and adaptability of the equipment. The modern packaging industry has increasingly higher demands for multi-variety, small-batch production, which requires production equipment to be able to quickly switch between different production tasks. However, if the punching device cannot automatically discharge material, the residual material needs to be manually cleaned every time the production task is changed. This not only increases the switching time, but may also lead to insufficient precision in equipment adjustment, affecting production efficiency and product quality.

[0028] To address the above problems, the following technical solution is proposed:

[0029] Referring to Figures 1 and 2, this utility model provides an automated punching device for packaging products, including a mounting frame 1, a hydraulic telescopic rod 2, a guide frame 3, and a punching assembly 4.

The punching assembly 4 also includes a second vent hole 4.9, which is opened on the punching cylinder 4.1 and coincides with the first vent hole 4.8.

[0032] Furthermore, when the hydraulic telescopic rod 2 is activated, the extension or retraction of the hydraulic telescopic rod 2 causes the guide frame 3 to move. The guide rod 3.1 slides back and forth on the mounting frame 1, and the end plate 3.2 causes the punching cylinder 4.1 and the fixing cylinder 4.7 to move.

[0033] The punching cylinder 4.1 moves towards the packaging product to punch holes. The cutting edge at the front end of the punching cylinder 4.1 punches holes in the packaging product. The excess material cut off from the packaging product will squeeze the push ring 4.2. The push ring 4.2 drives the branch rod 4.3 to move. The branch rod 4.3 drives the slide rod 4.4 to move.
