Description

Technical Field

[0001] The utility model relates to the technical field of cold stretch sleeve film packaging, in particular to an automatic conveying, separating and opening tubular M-shaped edge-inserted film and bag-making mechanism. Background Art

[0002] Stretch hood packaging is a method of forming a tubular film sleeve by separating and opening a tubular M-shaped inset film at room temperature or low temperature using a mechanical stretching device. This packaging method is currently very popular internationally and is widely used in single-piece or pallet packaging for chemical raw materials, fertilizers, food, electromechanical products, textiles, logistics, cement, building materials, metals, home appliances, beverages, pharmaceuticals, papermaking, printing, salt industry, refractory materials, mortar, gypsum, sugar industry, sanitary building materials, canning, and other tubular film packaging. Tubular M-shaped inset film is also often used in bag making.

[0003] However, in existing technologies, when making bags using tubular M-shaped insert films, the film often cannot be flexibly separated and opened. Furthermore, the bag-making device often cannot flexibly move the tubular M-shaped insert film up and down during the bag-making process, resulting in inconvenience during the bag-making process. Separation and opening of the tubular film and bag-making are often accomplished through motorized conveyor systems, or through a combination of mechanical, motor, and fan systems. While these methods can achieve their objectives, they suffer from high power and gas consumption, a complex number of mechanisms, high assembly costs, and complex maintenance. Utility Model Content
