Processing equipment of upper and lower membrane integrated packing bag and processing method of upper and lower membrane integrated packing bag

Abstract

The invention discloses processing equipment of an upper and lower membrane integrated packing bag and a processing method of the upper and lower membrane integrated packing bag, and relates to the technical field of packing bag processing equipment. The processing equipment of the upper and lower membrane integrated packing bag mainly comprises a main membrane conveying device, a lateral organ membrane conveying device, a lateral organ membrane folding device, a main membrane folding device, a tangent line device, a spot scalding device, a template forming device, a lateral organ angle-breaking device and a cutting device. According to the processing equipment of the upper and lower membrane integrated packing bag and the processing method of the upper and lower membrane integrated packing bag, a simple layer membrane is adopted as a packing bag raw material, a production mode of two-layer membranes adopted in traditional packing bag processing is replaced, the two-layer membranes arenot required to be pressed and scalded, the problem of deflection or unstable pressing occurring to press fit positions of the packing bag cannot be caused, and the firmness of the finished packing bag is greatly improved; and the simple layer membrane is adopted as the raw material, the material loss of the packing bag is reduced to the minimum, and generation of a large number of waste materials caused by edge cutting is reduced in the production process of the packing bag.

Description

technical field [0001] The invention relates to the technical field of packaging bag processing equipment, in particular to a processing equipment and a processing method for an integrated packaging bag with upper and lower films. Background technique [0002] Packaging bag refers to the bag used to pack various supplies, so that the goods are conveniently transported and stored during the production and circulation process, and are widely used in daily life and industrial production. Actual figures show that 80% of the plastic bags after use end up in Like ordinary garbage, it is transported to the landfill area for disposal, and only 7% of the plastic is recycled. [0003] There are two types of packaging bags: paper bags and plastic bags. Usually, the production cost of plastic bags is lower, but the environmental pollution caused is also more serious. In order to improve the recyclability of plastic bags, modern plastic bags are made more solid and firm. The designs and...

Problems solved by technology

[0003] There are two types of packaging bags: paper bags and plastic bags. Usually, the production cost of plastic bags is lower, but the environmental pollution caused is also more serious. In order to improve the recyclability of plastic bags, modern plastic bags are made more solid and firm. The design and color are also more beautiful, but they are mostly directly related to the brand trademark. The production process of packaging bags is inseparable from the support of equipment

[0004] Existing packaging bag production equipment usually uses pressing to process packaging bags, that is to say, the raw materials are two independent film materials, and the upper and lower film materials are pressed together by equipment. At the same time, although this kind of production method is simple and fast, there are many inferior plastic bags produced, such as the deflection of the press joint, and the press joint is not firmly pressed, resulting in the plastic bag being very easy to crack and of poor quality
