The invention relates to the technical field of plastic processing, in particular to a molding and production method of degradable and environment-friendly plastic bags from degradable plastic bag manufacturers. Degradable and environment-friendly plastic bags are generally made of plastic films blown from plastic raw materials.
First roll the blown plastic film, then heat seal and cut the rolled plastic film, so that the plastic film can be processed into an environment-friendly plastic bag. Due to the high temperature of plastic film formed by blow molding, it is necessary to cool the plastic film before coiling to prevent the overheated plastic film from deforming or adhering to each other during coiling. Most of the existing plastic films are cooled by increasing the rolling distance or blowing with a fan. The problems in the cooling process of plastic films are as follows:
1. Expanding the rolling range of plastic film has higher requirements on the working site, and the cooling effect of thicker plastic film is poor, so the cooling efficiency of plastic film blown by fan is slow, and the blowing range of fan is large, which will make work difficult.
2. The cooling mode of plastic film is relatively simple. For plastic film with different thickness, the cooling amount cannot be adjusted flexibly.
In order to solve the above problems, the invention provides a degradable and environment-friendly plastic bag forming and production method for degradable plastic bag manufacturers. The following environment-friendly plastic bag forming and production devices are used, including a support plate, an upper guide roller, an air cooling roller, a movable support plate, a water cooling roller and a water cooling bracket. The number of support plates is two. The upper guide roller is installed between the upper left ends of the support plate, and the lower left end of each support plate is provided with a transverse chute. The method of degradable plastic bag manufacturer is that the horizontal chute is connected with the movable support plate by sliding fit, and the air cooling roll is installed between the two movable support plates; The right end of the support plate is provided with a longitudinal chute, which is connected with the water-cooled bracket in a t-shaped structure; The water cooling roller is installed between two water cooling supports according to the method of degradable plastic bag manufacturer. The plastic film formed by the blow molding machine according to the method of the degradable plastic bag manufacturer can be transported downward through the upper guide roller, which can successively pass through the right end of the upper guide roller, the left end of the air cooling roller and the upper end of the water cooling roller. In this way, the plastic film can be cooled by air cooling and water cooling. The air cooling roller and water cooling roller can respectively cool both sides of the plastic film, thus increasing the cooling effect of the plastic film.
