Problems solved by technology

[0002] In order to increase the comfort and elasticity of the slippers, the midsole of the slippers is generally made of a relatively soft primary foamed EVA material, and then bonded together with the outsole made of rubber. Due to the different materials used in the outsole, this This kind of bonding is more difficult, so some heat treatment is required when the EVA midsole is coated with glue, but this process may cause the EVA midsole to expand and contract, which cannot be well matched with the outsole, and its firmness is not high. Easy to cause degumming

Embodiment 1

[0029] The production process of one-time foaming EVA slippers comprises the following steps:

[0030] (1) Soak the once-foamed EVA midsole in the UV treatment agent for 2 to 5 minutes, and transport it to the ultraviolet irradiation machine and X-ray irradiation machine in turn for irradiation at a transmission speed of 6m / min, so that the EVA midsole The polarity of the bottom is enhanced, and it is easy to glue;

[0031] (2) Use the automatic gluing machine to transport the glue to each gluing station through the rubber pipe, and then apply glue to the part where the upper needs to be bonded to the EVA midsole, and at the same time apply glue to the mesh foot of the EVA midsole , convey the glued upper and EVA midsole to the first baking machine, and bake at 60°C at a conveying speed of 1.5m / min;

[0032] (3) Then apply glue to the part of the shoe upper that has been baked once and needs to be bonded with the EVA midsole, and apply the outsole treatment agent on the inner...

Embodiment 2

[0039] The production process of one-time foaming EVA slippers comprises the following steps:

[0040] (1) First soak the foamed EVA midsole in the UV treatment agent for 2 to 5 minutes, and transport it to the ultraviolet irradiation machine and X-ray irradiation machine in turn for irradiation at a transmission speed of 8m / min, so that the EVA midsole The polarity of the bottom is enhanced, and it is easy to glue;

[0041] (2) Use the automatic gluing machine to transport the glue to each gluing station through the rubber pipe, and then apply glue to the part where the upper needs to be bonded to the EVA midsole, and at the same time apply glue to the mesh foot of the EVA midsole , convey the glued upper and EVA midsole to the first baking machine, and bake at 55°C at a conveying speed of 1.2m / min;

[0042] (3) Then apply glue to the part of the shoe upper that has been baked once and needs to be bonded with the EVA midsole, and apply the outsole treatment agent on the inne...

Embodiment 3

[0049] The production process of one-time foaming EVA slippers comprises the following steps:

[0050] (1) First soak the foamed EVA midsole in the UV treatment agent for 2 to 5 minutes, and transport it to the ultraviolet irradiation machine and X-ray irradiation machine in turn for irradiation at a transmission speed of 10m / min, so that the EVA midsole The polarity of the bottom is enhanced, and it is easy to glue;

[0051] (2) Use the automatic gluing machine to transport the glue to each gluing station through the rubber pipe, and then apply glue to the part where the upper needs to be bonded to the EVA midsole, and at the same time apply glue to the mesh foot of the EVA midsole , convey the glued upper and EVA midsole to the first baking machine, and bake at 50°C at a conveying speed of 1m / min;

[0052] (3) Then apply glue to the part of the shoe upper that has been baked once and needs to be bonded with the EVA midsole, and apply the outsole treatment agent on the inner...

Abstract

The invention discloses a foaming EVA slipper production process. The process includes the steps of EVA insole irradiation treatment, glue coating and bonding of vamps and EVA insoles, outsole pre-treatment, glue coating and bonding of the outsoles and the EVA insoles and pressing and shaping of the outsoles and the EVA insoles. By adopting the foaming EVA slipper production process, the EVA insoles and the outsoles can be bonded perfectly, the firmness of the produced slippers is high, and the slippers are not likely to be degumed.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a production process of one-time foamed EVA slippers. Background technique [0002] In order to increase the comfort and elasticity of the slippers, the midsole of the slippers is generally made of a relatively soft primary foamed EVA material, and then bonded together with the outsole made of rubber. Due to the different materials used in the outsole, this This kind of bonding is more difficult, so some heat treatment is required when the EVA midsole is coated with glue, but this process may cause the EVA midsole to expand and contract, which cannot be well matched with the outsole, and its firmness is not high. It is easy to cause degumming. Contents of the invention [0003] The purpose of the present invention is to provide a production process for one-time foaming EVA slippers, which can make the EVA midsole and the outsole of shoes perfectly bonded together, and the p...
