Description

Cold-sticking shoe adhesive pressing mechanism

Technical Field

The utility model relates to a shoemaking production facility technical field, concretely relates to cold-bond shoe viscose pressing mechanism.

Background

The shoes are used as necessities of daily life of people, play an important role in our life, people need to wear the shoes every day, different types of shoes are needed to be worn according to different time periods, and the different shoes worn by people mainly have five shoe production processes: gluing process, hot vulcanization process, injection molding process, mould pressing process and sewing process.

The shoe and boot gluing process is the most widely applied process in the shoe manufacturing industry at present, and has the advantages of suitability for various materials, high production efficiency and suitability for assembly line operation.

Taking glued shoes as an example, the main process flow of the process is as follows: cutting the lining and lining into upper (including edge trimming, edge folding, upper sewing, etc.) -making sole (including shaping, processing, upper tightening, etc.) combining sole (sole combining), drying and setting, last taking out, checking, etc.

The shoe and boot hot vulcanization process is divided into a hot vulcanization pasting process and a hot vulcanization mould pressing process, and the former process is more widely applied. The hot vulcanization shoe making process is mainly applied to the production of rubber sole shoes such as travel shoes, sports leisure shoes and the like.

The main flow of the hot vulcanization pasting process is as follows: manufacturing a rubber part for manufacturing an upper, forming, vulcanizing and delasting.

Injection molding is a method of manufacturing shoes by injection molding. The technology is mostly applied to shoes such as travel shoes, sports leisure shoes and the like. The injection molding process is divided into a whole shoe injection molding process (separately manufacturing uppers) and a sole injection molding process, and the sole injection molding process can be divided into a single-color injection molding process and a multi-color injection molding process. The main process of injection molding is to compress the material in the injection molding device, plasticize (solid plastic is converted into fluid), homogenize, inject the fluid plastic into the mold cavity of the shoe through the injection channel of the mold, and obtain the molded product after cooling.

The mould pressing technology is widely applied to the shoe varieties with high requirements on the combination strength of the upper and the sole, such as labor protection shoes, military shoes and the like. The mould pressing technology is divided into lasting mould pressing and lasting mould pressing. The main flow of the lasting and mould pressing process is that the upper with the lasting is sleeved on an aluminum last with the same type of a mould press after the upper is fluffed and pulled out of the original last, an adhesive is coated on the upper, and the like, then a sizing material is put into a bottom mould, and the upper is heated, melted and pressed downwards through the mould press, finally the sizing material is melted and pressed and is tightly synthesized with the upper, and the whole process is basically finished.

In cold-bond shoes, the viscose is a very important process, and particularly, when the cold-bond shoes are pressed, the manual pressing bonding is low in efficiency and high in cost, and because the manual pressing is easy to cause uneven pressing force and insufficient bonding strength of places with weak pressing force, the cold-bond shoes are always easy to come unstuck when entering the market after the shoes are processed, and the quality problem of cracking causes large return maintenance amount, and the customer experience is poor, so that the quantity of sales is extremely fatal.

Therefore, for solving the above problems, a cold-bonded shoe adhesive pressing mechanism is needed, which can improve the pressing efficiency and further improve the pressing quality of the cold-bonded shoe during the adhesive bonding, so that the adhesive bonding between the upper and the sole is uniform, the bonding strength is high, the overall bonding effect of the upper and the sole is improved, the integrity is improved, and the service life of the finished shoe is prolonged.
