Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bag processing, in particular to a punching device for packaging bag processing. Background Art
[0002] Packaging bags refer to bags used to package various items, which make it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to garbage dumps for treatment like general garbage, and only 7% of plastics are recycled. During the processing of packaging bags, it is sometimes necessary to use a punching device to punch the packaging bags to facilitate the subsequent discharge of air from the packaging bags during use. In the prior art, the punching of packaging bags is often achieved by the cooperation of a punching cutter head and a die hole. During the punching process, the elastic force generated by the deformation of the spring is used to hold the packaging bag by a limiting pressure plate to prevent the packaging bag from moving during the punching process. However, during the downward movement of the limiting pressure plate, the space between the limiting pressure plate and the packaging bag will be reduced, allowing air to flow. Because the packaging bag is light in weight, it is easy to move under the influence of airflow, affecting the quality of the punching of the packaging bag. Utility Model Content

[0023] The limiting mechanism 8 is arranged on the surface of the pressing plate 4. The limiting mechanism 8 includes a guide tube 81 and a limiting shell 82.

The tension spring 83 is respectively arranged between the upper surface of the pressing plate 4 and the top wall of the limiting shell 82. The tension spring 83 is movably sleeved on the outer arc surface of the guide tube 81. When the lower surface of the limiting shell 82 contacts the packaging bag, as the pressing plate 4 continues to move downward, the guide tube 81 The tension spring 83 is stretched to generate elastic force by sliding relative to the limiting shell 82. Under the elastic force of the tension spring 83, the packaging bag is evenly pressed on the surface of the punching plate 7. The limiting mechanism 8 also includes a positioning column 84 and a tension spring 85. The positioning column 84 is respectively vertically slidably connected to the sliding holes at the four corners of the lower surface of the limiting shell 82.

When the disc at the lower end of the positioning column 84 first contacts the packaging bag, as The pressing plate 4 continues to move downward, the positioning column 84 slides relatively with the limiting shell 82, and the tension spring 85 is stretched to generate elastic force. Under the elastic force of the tension spring 85, the four corners of the packaging bag are pressed against the surface of the punching plate 7 to prevent the air flow between the limiting shell 82 and the punching plate 7 from causing the packaging bag to move. The limiting mechanism 8 also includes a round tube 86 and a pressure ring 87. The round tubes 86 are respectively arranged at the lower end of the limiting shell 82.

Under the elastic force of the spring 88, the outer edge of the punching position of the packaging bag is pressed and held. The four corners of the lower surface of the limiting shell 82 are provided with receiving holes 10, and the receiving holes 10 are installed in cooperation with the disc at the lower end of the positioning column 84 to provide space for the disc at the lower end of the positioning column 84 to be stored, thereby ensuring that the lower surface of the limiting shell 82 can contact the packaging bag.
[0024] The working principle of the punching device for packaging bag processing provided by the utility model is as follows: during the packaging bag processing, the packaging bag is placed on the upper surface of the punching plate 7, and the electric push rod 3 is started by the single chip microcomputer 9. The telescopic end of the electric push rod 3 drives the pressing plate 4 to move downward. During the downward movement of the pressing plate 4, the disc at the lower end of the positioning column 84 first contacts the packaging bag, and the elastic force of the second tension spring 85 is less than the elastic force of the first tension spring 83. As the pressing plate 4 continues to move downward, the positioning column 84 slides relative to the limiting shell 82, and the second tension spring 85 is stretched to generate elastic force. Under the elastic force of the second tension spring 85, the four corners of the packaging bag are pressed against the surface of the punching plate 7 to prevent the air flow between the limiting shell 82 and the punching plate 7 from causing the bag to be stuck. The bag is displaced, and then the lower surface of the limiting shell 82 contacts the packaging bag. As the pressure plate 4 continues to move downward, the guide tube 81 and the limiting shell 82 slide relative to each other, and the tension spring 83 is stretched to generate elastic force. Under the elastic force of the tension spring 83, the packaging bag is evenly pressed and held on the surface of the punching plate 7. Finally, the pressure ring 87 contacts the outer edge of the punching position of the packaging bag. As the pressure plate 4 continues to move downward, the round tube 86 and the pressure ring 87 slide relative to each other, and the spring 88 contracts to generate elastic force. Under the elastic force of the spring 88, the outer edge of the punching position of the packaging bag is pressed and held, completing the accurate and firm limiting of the packaging bag. Then, the punching tool head 5 cooperates with the die hole on the surface of the punching plate 7 to realize the punching processing of the packaging bag.
