Abstract

The invention discloses a cooling forming module for bag outer shell four-layer co-extrusion. The cooling forming module comprises a four-layer co-extrusion mold and a plate cooling forming device, wherein the four-layer co-extrusion mold comprises a division feed inlet, a confluence discharge opening and fixed wings; and the plate cooling forming device comprises fixed seats, air curtain machines, heat-conducting pipes and side fixed plates. According to the cooling forming module, through design of the air curtain machines, external dust is prevented from falling on a plate before the plateis not cooled, and a dust prevention effect is achieved; and besides, the gravity effect on the outer shell plate before forming is reduced, namely, supporting force between the outer shell plate andthe heat-conducting pipes is reduced, deformation is prevented, and product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of producing PVC case shells, in particular to a four-layer co-extrusion cooling molding module for case bag shells. Background technique [0002] Luggage is a general term for bags, and it is a general term for various bags used to hold things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, satchels, waist bags and various trolley cases. The materials of bags are more diverse, such as leather, PU, ​​polyester, canvas, cotton and linen, etc. Luggage is a kind of daily necessities indispensable for people. At present, people are still developing and experimenting with various materials to make bags. Lightweight, high-strength, and beautiful bags are the focus of the current reform of new bags. [0003] Existing PVC bags are more and more popular, especially the PVC bags produced by four-layer co-extrusion molds, which have high shell strength, light material weight, ...
