Double film bag type automatic packaging machine and automatic packaging process thereof

Abstract

The invention discloses a double film bag type automatic packaging machine and an automatic packaging process thereof. The machine comprises a lower film winding mechanism, an upper film winding mechanism, a bag body pulling mechanism, a three-side heat sealing mechanism, a bag clamping mechanism, a bag cutting mechanism, a side cutting mechanism, a bag opening mechanism, a sealing mechanism and apushing mechanism, and strip-shaped films exported by the lower film winding mechanism and the upper film winding mechanism are superposed on each other; the bag body pulling mechanism clamps the ends of the sides of the strip-shaped films superposed on each other; the three-side heat sealing mechanism continuously heat-closes the three side edges of the strip-shaped films; the bag clamping mechanism clamps the inner side portion of an outer end bag body, and the bag cutting mechanism cuts the outer end bag body from the strip-shaped films; the side of the bag body is trimmed neatly by the side cutting mechanism; the bag opening mechanism opens a bag mouth of the bag body, and a product on the pushing mechanism is pushed into the bag body through the bag mouth; the sealing mechanism heat-closes the bag mouth of the bag body. The machine can simultaneously achieve the production of a packaging bag and the packaging of a kit.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a double-film bag-forming automatic packaging machine and an automatic packaging process thereof. Background technique [0002] Packaging is the overall name of containers, materials and auxiliary materials used in a certain technical method to protect products, facilitate storage and transportation, and promote sales in the circulation process; it also refers to the process of using containers, materials and auxiliary materials to achieve the above purposes Operational activities in which certain technical methods are applied; packaging is a very important process in the industrial production process. Packaging includes manual packaging and automatic packaging according to the process, and can be divided into bag packaging and box packaging according to the packaging material; for small products, such as kits used in the medical field, when individual packaging is required, ...

AI Technical Summary

Problems solved by technology

Packaging includes manual packaging and automatic packaging according to the process, and can be divided into bag packaging and box packaging according to the packaging material; for small products, such as kits used in the medical field, when individual packaging is required, plastic materials are generally used The packaging bag is used as the packaging carrier, and the single kit is put into a single plastic packaging bag and then the packaging bag is glued to achieve the purpose of packaging; in the traditional packaging method, the enterprise generally purchases the produced packaging bag from the supplier. When packaging, the product is directly put into the packaging bag by manual or automatic equipment; the following defects exist in this method: 1. The packaging bag needs to be purchased, which leads to an increase in packaging costs; 2. Different sizes and shapes in the actual production process The product has different requirements on the size and material of the packaging bag. The size and material of the purchased packaging bag cannot be automatically adapted according to the actual use requirements, and the production adaptability is poor; 3. The existing single automatic packaging equipment cannot solve the problem of film lamination, Automatic packaging processes such as film clamping, three-side heat sealing, bag cutting, side cutting, bag opening, product bagging, and sealing; and the packaging capacity is low; 4. For medical kits (with multiple side-by-side liquid injection Cavity, which can be used to extract various specimens in the process of physical examination, such as blood, urine, saliva, etc.) for production and packaging. At present, there is no dedicated automatic packaging equipment, and the existing packaging production capacity is extremely low, which can only reach 400pcs / h, therefore, the design and development of an automatic packaging equipment is in line with the development of the industry and meets the market demand
