Problems solved by technology

However, when the existing safety shoes are sewn, the upper and the lining are often bonded first, and then cut into the required shape of the upper, which leads to a waste of materials. What is cut is the upper after bonding. The vamp and lining can no longer be reused, and at the same time, it is easy to cause defects such as burrs and glue at the joint between the sole and the upper, which makes the alignment of the upper and the vamp inaccurate, and the tightness of the butt joint cannot be guaranteed after sewing , prone to gaps, but also affect the appearance

Embodiment 1

[0038] A manufacturing process of safety shoes, the steps of which are:

[0039] S1 sole preparation: use wear-resistant materials to prepare a wear-resistant bottom plate in the mold, and bond the elastic plate and the foot pad to the wear-resistant bottom plate in sequence. The mold for the preparation of the wear-resistant bottom plate is a mold with pattern grooves, The mold produces a non-slip wear-resistant bottom plate, and the wear-resistant bottom plate is fixed on the bottom surface of the sole by hot melt adhesive, and the elastic plate is a rubber plate;

[0040] S2 upper pretreatment: cleaning, disinfection, heating and softening of the upper, washing the upper with water, adding a softener to the water absorption solution to soften the upper so as to facilitate the subsequent shaping process, rolling water and drying, drying The temperature is 110°C, steam ironing and shaping treatment are carried out to make the upper form a three-dimensional curved surface shap...

Embodiment 2

[0051] A manufacturing process of safety shoes, the steps of which are:

[0052] S1 sole preparation: use wear-resistant materials to prepare a wear-resistant bottom plate in the mold, and bond the elastic plate and the foot pad to the wear-resistant bottom plate in sequence. The mold for the preparation of the wear-resistant bottom plate is a mold with pattern grooves, The mold produces a non-slip wear-resistant bottom plate, and the wear-resistant bottom plate is fixed on the bottom surface of the sole by hot melt adhesive, and the elastic plate is a rubber plate;

[0053] S2 upper pretreatment: cleaning, disinfection, heating and softening of the upper, washing the upper with water, adding a softener to the water absorption solution to soften the upper so as to facilitate the subsequent shaping process, rolling water and drying, drying The temperature is 120°C, steam ironing and shaping treatment are carried out to make the upper form a three-dimensional curved surface shap...

Abstract

The invention discloses a manufacturing process of safety shoes. The manufacturing process comprises the following steps: S1, soles preparing; S2, vamp pretreatment; S3, shearing and forming; S4, lining fixing; S5, edge modification; S6, primary adhesion; S7, adhesive removing; S8, punching; S9, stitching; S10, secondary adhesion; and S11, drying. According to the manufacturing process, the vamp and the lining are cut into proper shapes respectively and then bonded, so that materials can be greatly saved, the situation that secondary utilization cannot be achieved due to waste is avoided, trimming and degumming procedures are conducted, inaccurate alignment of the upper and the vamp is avoided, flaws are reduced, and attractiveness is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of shoe production, in particular to a production process of safety shoes. Background technique [0002] In the current work and production, safety shoes need to be worn in some working environments to ensure the safety of workers. However, the existing safety shoes structure is mostly made by splicing the upper and the sole, which requires sewing operations. . However, when the existing safety shoes are sewn, the upper and the lining are often bonded first, and then cut into the required shape of the upper, which leads to a waste of materials. What is cut is the upper after bonding. The vamp and lining can no longer be reused, and at the same time, it is easy to cause defects such as burrs and glue at the joint between the sole and the upper, which makes the alignment of the upper and the vamp inaccurate, and the tightness of the butt joint cannot be guaranteed after sewing , It is easy to produce gaps, a...
