Description

Glue spraying head, automatic glue spraying device and glue spraying method thereof

technical field

The invention relates to a glue spraying device, in particular to a glue spraying head, an automatic glue spraying device and a glue spraying method.

Background technique

In the manufacturing process of sports shoes, the lining and the upper need to be bonded together by glue. At present, the method of manual gluing is mainly used. When gluing, use a squeegee to dip the glue, and then apply the glue along the inner side of the upper. Because the shoes are U-shaped, it is inconvenient to apply glue, and there are problems of uneven glue application and excessive glue application in manual glue application, and the glue application time of each shoe is longer, resulting in higher glue application costs.

Contents of the invention

In order to solve the above problems, the present invention provides a glue-spraying method to distribute glue evenly on the glue-applied surface. The glue-spray head uses less glue, is fast, and can effectively reduce costs. The specific technical solution is:

The glue spraying head includes: a glue spraying seat, the glue spraying surface is provided with a glue spraying surface, a glue outlet hole and an air injection hole, the glue spraying surface is corresponding to the surface to be glued, and the glue spraying surface is provided with different Less than one air injection hole, the glue outlet is set on one side of the glue spraying surface, and not less than one, the glue outlet is set opposite to the air injection hole, and the air injection hole is used for glue outlet When the glue comes out of the hole, the jet atomizes the glue and blows it to the surface to be glued.

By adopting the above technical scheme, the glue spraying surface corresponds to the surface to be glued so that the glue is directional sprayed, ensuring that the glue can be sprayed to the inner surface of the shoe upper.

When the glue is extruded, it is atomized by the high-pressure gas ejected from the jet hole, that is, the high-pressure gas blows the glue away to form small droplets, which are blown onto the inner surface of the shoe upper to realize the spraying of the glue.

When the glue is atomized, it can form a larger range of spraying, and make the glue distribution more uniform, which greatly reduces the amount of glue used.

Due to the wide range of glue spraying, all the glue on the inner side of the upper can be completed in one spraying glue, so the speed of gluing on the upper is greatly improved, the working hours are reduced, and the amount of glue used is less, which effectively reduces the cost.

Further, the glue outlet holes correspond to the air injection holes one by one or are arranged in a staggered manner.

By adopting the above technical scheme, the glue outlet hole corresponds to the air injection hole one by one, that is, the glue outlet hole is directly facing the air injection hole, and a fan-shaped glue spraying surface can be formed, and the glue spraying range is large.

The glue outlet holes and air injection holes are arranged alternately, that is, the glue outlet holes are set on the side of the air injection holes, so that the glue can spread better and distribute evenly.

Further, there are no less than three air injection holes, and they are arranged at equal intervals; there are no less than two glue outlet holes, and the glue outlet holes are arranged at equal intervals, and are located between two adjacent air injection holes.

By adopting the above technical scheme, when the glue outlet hole is directly facing the air injection hole, the glue is subjected to a larger air pressure, the airflow speed is faster, and the impact formed is larger. Although a fan-shaped glue spray surface can be formed, there is more glue in the center. There is less glue on both sides, and the uniformity is poor, so it is necessary to set up multiple glue outlet holes and air injection holes.

When the air injection holes and the glue outlet holes are arranged alternately, it can reduce the influence of the air injection on the glue. A turbulent flow can be formed between two adjacent jet holes, the turbulent flow can atomize the glue evenly, and the air pressure and air velocity are small, the atomization time of the glue is longer, the atomization of the glue is more thorough, and the glue can be evenly distributed. Spray on the inner side of the upper under the push of the airflow to form a uniform coating layer.

Further, the top of the glue spray seat is provided with a glue tank, and the bottom of the glue tank is provided with a glue outlet; it also includes an upper cover plate, which is fixed on the top of the glue spray seat, and the A glue inlet hole is provided on the upper cover, and the glue inlet hole communicates with the glue tank.

By adopting the above technical scheme, the glue tank facilitates the processing of glue feeding and glue spraying seat. The glue groove enables the glue to flow out evenly from each glue outlet hole after entering.

Further, a glue collecting groove is provided at the bottom of the glue tank, and the glue collecting groove is located on one side of the glue outlet hole.

By adopting the above technical scheme, when the glue-collecting tank stops feeding glue, the glue can flow back into the glue-collecting tank, so as to avoid continuous dripping of glue from the glue outlet hole.

Further, the glue spray seat is also provided with a guide plate, and the guide plate is arranged on the other side of the glue spray surface.

By adopting the above technical scheme, the glue spray surface, the guide plate and the glue outlet plate where the glue outlet is located form a glue spray groove together, which can limit the upper and lower positions of the glue diffusion during glue spraying, and avoid the large spread of glue spraying out of the upper. .

Further, the glue spraying surface is a circular arc surface.

By adopting the above technical solution, the arc surface can match the inner surface of the shoe upper, ensuring that the glue covers the position to be glued.

An automatic glue spraying device, comprising the glue spraying head; a glue spraying rod, the glue spraying head is installed on the top of the glue spraying rod; a glue spraying linear module, the glue spraying rod is fixed on the glue spraying rod Glue the sliding table of the linear module.

By adopting the above technical scheme, the glue spraying linear module drives the glue spraying head up and down to realize all the glue spraying on the inner surface of the shoe upper.

The glue spray rod facilitates the installation of the glue spray head, and solves the problem that the linear module is too large to be inserted into the shoe opening.

A glue spraying method, the glue outlet hole is between the air jet hole and the surface to be glued, and the glue is sprayed by the air jet hole to atomize the glue and blow it to the surface to be glued.

Further, the glue outlet hole is between two adjacent air injection holes; when spraying glue, first spray air and then spray glue; when stopping glue spraying, first stop glue spray and then stop air spray.
