Surface insect spot defect preventive method of plastic-aluminum composite belt

Abstract

The invention discloses a surface insect spot defect preventive method of a plastic-aluminum composite belt. The method comprises the following steps that a glass room with a roof is arranged in the surrounding of a film covering machine, the surrounding of the glass room is enclosed by a stainless-steel insect preventive net, and a door additionally provided with springs and capable of being closed automatically is arranged in the glass room; and in the glass room, a low-power exhaust fan is arranged opposite to an original lamp which is used to observe the surface condition of an overlay film, phototactic winged insects which enters the glass room due to light via a non-sealed area in entrance and exit of the plastic-aluminum composite belt are blown off the surface of the plastic-aluminum composite belt, the low-power exhaust fan is positioned in the side surface of the plastic-aluminum composite belt, and an air intake guard net of the low-power exhaust fan is provided with an insect preventive net which can be cleaned and replaced regularly. Thus, insect spot defects can be effectively prevented from forming in the surface of the plastic-aluminum composite belt, the surface quality of the plastic-aluminum composite belt is improved, the risk of goods rejection due to insect spot problems is reduced, and the benefit of a company can be improved obviously.

Description

technical field [0001] The invention relates to a method for preventing insect spot defects on the surface of an aluminum-plastic composite belt. Background technique [0002] Aluminum-plastic composite tape is widely used in communications, optical cables, and cable covering materials. It has good toughness, adhesion, heat sealing, and acid and alkali corrosion resistance. The main customers of the aluminum-plastic composite tape are some large customers, the concentration of customers is relatively high, and the quality requirements of the customers are relatively high, and the surface quality of the aluminum-plastic composite tape is relatively strict. Every year when summer and autumn enter, the complaints of customers on the surface quality of aluminum-plastic composite tapes increase significantly, and later research found that they mainly focus on surface spots. After on-site research and analysis, it was found that these spots with a large proportion were due to the...

Problems solved by technology

After on-site research and analysis, it was found that these spots with a large proportion were due to the fact that the aluminum-plastic composite tape fell to the surface of the aluminum-plastic composite tape due to moths and mosquitoes during the lamination process, and then followed the aluminum-plastic composite tape into the laminating machine and was pressed. On the surface of the aluminum-plastic composite tape, it is then covered by plastic film, which leads to insect spots on the surface of the aluminum-plastic composite tape, which seriously affects the surface quality of the aluminum-plastic composite tape

At present, no disclosed method has been found to prevent the generation of surface insect spot defects such as aluminum-plastic composite tapes. The present invention discloses a method that can effectively prevent and reduce insect spot defects in combination with production practice
