Device for manufacturing bubble bag

Abstract

The invention discloses a device for manufacturing a bubble bag, which comprises a film discharging device, a transverse edge sealing device, an air supply device, a longitudinal edge sealing device and a cutting device which are sequentially connected. The film discharging device can output an upper film and a lower film which correspond to each other; the transverse edge sealing device comprises a plurality of transverse devices and first liftable heating blocks; the air supply device can inflate the bubble bag; the longitudinal edge sealing device comprises at least one longitudinal device and one second liftable heating block; and the cutting device comprises at least one longitudinal device and a liftable cutter. The device is characterized in that the number of the first heating blocks for transverse edge sealing can be regulated. When a plurality of heating blocks simultaneously work, a plurality sections of longitudinal positions of the upper film and the lower film can be simultaneously subjected to transverse edge sealing; and by regulating the number of the first heating blocks which participate in working, the distance between two adjacent sections of transverse sealed edges can be changed, so that the width of the bubble bag can be changed to regulate the size of the bubble bag. The device is suitable for producing the bubble bags with different sizes and specifications.

Description

technical field [0001] The invention relates to a packaging bag manufacturing device, in particular to a bubble bag manufacturing device. Background technique [0002] Bubble bag is a kind of transparent flexible packaging material that is currently widely used and has a wide range of uses. By injecting gas into the packaging bag to form air bubbles to prevent product impact, to ensure that the product is protected when it is shaken, and it also has the function of heat preservation and heat insulation. It is suitable for packaging or turnover of different products in all walks of life. Because the bubble bag The middle layer is full of air, so it is light, elastic, sound-proof, shock-proof, and wear-resistant, and waterproof, moisture-proof, and compressive. In use, different fields have different size requirements for bubble bags. When it is necessary to mass produce bubble bags of different sizes, it is usually to choose a different bubble bag manufacturing device or adj...

AI Technical Summary

Problems solved by technology

In use, different fields have different size requirements for bubble bags. When it is necessary to mass produce bubble bags of different sizes, it is usually to choose a different bubble bag manufacturing device or adjust the structure of the bubble bag itself. Both methods need to invest a lot of material resources or manpower, which is not conducive to improving production efficiency.
