At present, there are many kinds of shoes on the market, but most of the existing shoes are only improved on the structure and performance of the sole or the upper surface, and seldom focus on the quality stability of the combination of the upper and the bottom and the comfort of the foot. The quality stability of the sole combination and the fit and comfort of the product are closely related to the entire process of shoemaking, and each step has a certain impact on the quality of the shoe

Embodiment 1
[0038] This embodiment provides a forming process for cold-bonded shoes, including forming of the upper with a last, pretreatment of the upper with a last, pretreatment of the sole, cold-bonding of the upper and the sole, untying the shoelace, pulling the last, and finishing.
[0039] 1. The forming of the body with a last includes the following steps:
[0040] A1. Prepare shoe lasts, lining boards and finished uppers with matching sizes. The processed uppers include cutting, laser engraving, sewing and splicing, hot pressing, printing and mesh feet of each material part of the upper. The stitching of the mesh feet requires the bottom line to be tightly adjusted and the inner cloth to be completely pressed, with a margin of 3mm to 5mm, and the outer edge of the mesh feet should be trimmed to leave a thickness of 0.4mm to 0.6mm.
[0041] A2. Use the heel shaping machine to shape the upper with a pressure of 5kg and a time of 18 seconds.
[0042] A3. Wear the shoelace along the...
Embodiment 2
[0062] This embodiment provides a forming process for cold-bonded shoes, including forming of the upper with a last, pretreatment of the upper with a last, pretreatment of the sole, cold-bonding of the upper and the sole, untying the shoelace, pulling the last, and finishing. On the basis of the above-mentioned first embodiment, this embodiment further includes glue replenishment, drying in the oven, and post-pressurization between the steps D2 and D3, specifically to slightly repair the insufficient glue position between the edge of the sole and the upper. After the glue is filled, it is sent to an oven for drying at a temperature of 45±5°C. After drying, it is mechanically pressed on a pressing machine with a pressure of 30kg-40kg and a time of 8 seconds to 10 seconds.

Abstract
The invention discloses a cement shoe molding technology. The technology comprises the steps of molding an upper body with a shoe last, wherein heelpiece molding, shoelace tying, upper part steaming, white glue spraying, front upper pulling, waist upper pulling, heel lasting pulling, fixed point drawing and sulphurating shape stabilizing are performed; preprocessing the upper body with the shoe last and a shoe sole, wherein half meshes and the shoe sole are subjected to roughing, scrap removal, water wiping away, second oven feeding, primary surface glue / base glue spraying, third oven feeding, secondary surface glue / base glue spraying and fourth oven spraying; performing cold building on the shoe upper and the shoe sole, wherein pairing and fixed point alignment are performed, manual pressure fitting, mechanical press-fitting and refrigeration shape stabilizing are performed; shoelace undoing, last pulling-out and arrangement. Due to fixed point drawing, it is ensured that the shoe upper and the shoe sole combined positions are accurate, operation is easy, standard operation is performed, the shoe is prevented from deflecting, the shoe upper and the shoe sole are combined more firmly and stably due to multiple procedures such as glue spraying, multiple drying, half mesh processing and adhesive repairing, durability is achieved, the binding interface of a middle lining plate, the half mesh and the shoe sole is more smooth and firm, and the foot feeling and the wearing comfort level are improved.
Description
technical field [0001] The invention relates to the technical field of footwear, in particular to a cold-bonded shoe forming process. Background technique [0002] With the development of modern science and technology and the improvement of people's living standards, shoes are one of the indispensable necessities in people's lives, and the comfort and health of shoes are more and more paid attention to by customers. At present, there are many kinds of shoes on the market, but most of the existing shoes are only improved on the structure and performance of the sole or the upper surface, and seldom focus on the quality stability of the combination of the upper and the bottom and the comfort of the foot. The quality stability of the sole combination and the fit and comfort of the product are closely related to the entire process of shoemaking, and each step has a certain impact on the quality of the shoe. Contents of the invention [0003] In order to overcome the technical ...
