Description

Technical Field

[0001] The utility model relates to the technical field of punching for food packaging bag production machines, and specifically relates to a punching die for a food packaging bag production machine. Background Technique

[0002] Food packaging bags are material containers used for packaging food, which play important roles such as protecting the quality of food, facilitating storage and transportation, providing product information, and promoting sales. There are various types of food packaging bags, and common ones include plastic packaging bags (such as polyethylene, polypropylene, etc.), paper packaging bags, aluminum foil packaging bags, etc. The design and material selection usually take into account the characteristics of food, such as moisture-proof, anti-oxidation, light-proof, freshness preservation, etc.

[0003] Currently, common plastic food packaging bags need to be punched at the top so that the packaging bags containing food can be hung for display; the punching holes on the packaging bags have various forms, but in common punching dies, the punch and the punching hole are both of a single type, with a small application range; in order to meet the different forms of punching holes on different packaging bags, different punching dies need to be made, and the overall equipment cost is relatively high. Therefore, the existing punching dies have the problems of a small application range and a relatively high overall equipment cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a punching die for a food packaging bag production machine to solve the problems raised in the above background technique.

One end of the threaded rod is fixedly connected with a handwheel. The other end of the threaded rod is rotatably connected with a rectangular clamping block. The rectangular clamping block is adapted to the rectangular groove.

[0013] The utility model provides a punching die for a food packaging bag production machine. It has the following beneficial effects:

[0014] (1) Through the cooperation among the fixing block, rotating rod, supporting block, fixing plate, positioning rod, spring, backing plate, pressing plate, and rotating drum, the present utility model can evenly flatten the packaging bag material to be punched, avoiding wrinkles or unevenness on the material surface from affecting the accuracy and integrity of punching, thereby improving the punching quality, keeping the packaging bag in a stable position and state during the punching process, reducing punching deviation caused by material movement, improving the punching accuracy and consistency. Regardless of the thickness, hardness, or material of the packaging bag material, the flattening and transmission part can play a role to ensure good punching effect, increasing the adaptability of the equipment to various materials.

[0015] (2) Through the cooperation among the support plate, mounting plate, cylinder, connecting rod, mounting circular plate, card slot, fixed circular plate, rotating block, punching head, slide rail, punching bottom plate, handwheel, positioning block, rectangular clamping block, and rectangular groove, the present utility model can quickly replace punching heads and punching slots with different specifications, shapes, and sizes according to different production requirements to meet diverse punching requirements, such as different hole diameters, to adapt to different packaging designs. When the punching head or punching slot is worn or damaged, there is no need to replace the entire mold, only the corresponding parts need to be replaced separately, saving the high cost of replacing the mold. The position of the punching bottom plate can be flexibly adjusted according to the hole diameter size to adjust to the appropriate punching slot. Description of the Drawings
