Special-shaped frame splicing process for buffering packaging material

Abstract

The invention discloses a special-shaped frame splicing process for a buffering packaging material. According to the product requirement, the packaging material is measured, the area shape is calculated, by means of cutting of a vertical cutting machine, the packaging material is cut into packaging sheet materials, and then the positions, the sizes and the shapes of outer hollow-out portions, inner hollow-out portions, breaking splicing ports and coupling splicing ports are calculated; a manufacturing mold performs oil pressure forming on the packaging sheet materials; leftover materials are removed; and the coupling splicing ports are inwards folded by 90 degrees, and the breaking splicing ports are in butt joint with a hot air gun for blowing hot bonding. By means of the process, material waste can be greatly reduced, use of the hot air gun is reduced, the manual operation procedures are reduced, the special-shaped frame splicing mold process is used, oil pressure EPE, EPP or paper products are included, the material waste can be greatly reduced, the production efficiency is improved, the labor force is reduced, cost is reduced, the electricity consumption is reduced, the environment is protected, and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a special-shaped frame assembly process for cushioning packaging materials. Background technique [0002] At present, the packaging industry uses the most widely used EPE, EPP and paper frames, which are used for the cushioning and protection packaging of fragile products. Traditional EPE, EPP and paper product frames are produced according to the shape of the product. Molds are made in a piece of EPE, EPP or paper products pass through a hydraulic press to extrude the finished product. Since the center part of the frame is hollow, the material in the center part is treated as scrap material, which wastes a lot of raw materials. The current market price of rubber particles is about 20,000-22,000 yuan / ton. It is about 10T / month, and the peak period reaches 15T / month. If it is independently cut into more than 4 small parts and processed by glue sticking or hot air blowing, a large area nee...

[0002] At present, the packaging industry uses the most widely used EPE, EPP and paper frames, which are used for the cushioning and protection packaging of fragile products. Traditional EPE, EPP and paper product frames are produced according to the shape of the product. Molds are made in a piece of EPE, EPP or paper products pass through a hydraulic press to extrude the finished product. Since the center part of the frame is hollow, the material in the center part is treated as scrap material, which wastes a lot of raw materials. The current market price of rubber particles is about 20,000-22,000 yuan / ton. It is about 10T / month, and the peak period reaches 15T / month. If it is independently cut into more than 4 small parts and processed by glue sticking or hot air blowing, a large area needs to be pasted with a hot air gun or glue. The monthly electricity cost is about 5W. The paste should be smooth and firm. The dislocation of the adhesive surface is allowed to be ≤ 1.5mm. etc. have certain defects and abnormalities, resulting in high labor costs, which are not suitable for the scientific and environmentally friendly production concept of modern enterprises.
