Conventionally, in the manufacture of rubber gloves for high voltage of this kind, a glove mold is dipped in a stock solution to adhere and form a glove film on the surface of the glove mold, and the glove film is dried and solidified and vulcanized.
It is done by removing the glove membrane from the glove mold,
In this manufacturing work, the glove mold soaking time and withdrawal speed, the temperature of the glove mold and the undiluted solution, and the work processes such as shaking off the liquid adhering to the surface must be performed extremely quickly, and a delicate feeling is required. He relied on manual work by skilled workers.

[0004]

However, such advanced work by skilled workers has become a bottleneck for technological innovation, such as passing on technology for successors, exporting manufacturing technology, and expanding production equipment. Also, from the standpoint of improving and improving the working environment, mechanization and labor saving have been desired.

Therefore, it is possible to export the manufacturing technology and expand the production amount, and to provide a manufacturing method and a manufacturing facility for the rubber gloves for high voltage which can contribute to the improvement of the working environment.

[0006]

In order to solve the above-mentioned problems, a method for producing a high-voltage rubber glove of the present invention is to hold a glove mold preheated by a glove film forming device, immerse it in a stock solution, and extract it. After forming a glove film on the surface of the glove mold, it is delivered to the stock solution shaker, the stock solution shaker rotates the glove mold at high speed to shake off the droplets adhering to the surface of the glove film, and the glove transfer device The glove mold is carried into a drying device, the glove film is dried and solidified, and then the glove film is vulcanized and released from the glove mold.

Further, in the above method, the glove mold with the glove membrane formed thereon is rotated and moved at a high speed from a lower position to a higher position by the stock solution shaking device to shake off the stock solution, and the moving speed of the glove mold is moved to an intermediate position in the first half. After suddenly accelerating to the maximum speed, the speed is gradually reduced.

Furthermore, in the high voltage glove manufacturing facility of the present invention, the glove film is immersed in the stock solution to adhere a glove film to the surface thereof, and the glove film is dried and solidified and vulcanized. A high-voltage glove manufacturing facility that removes the mold from the mold to manufacture high-voltage gloves, in which a preheated glove mold is dipped in the stock solution in a dipping tank to form a glove film on the surface. Device and glove mold with glove film formed on it are rotated and moved at high speed to shake off the droplets adhering to the surface of the glove film, and glove mold that conveys the glove mold from which the stock solution has been shaken to the drying device. And a device.

Furthermore, in addition to the above-mentioned structure, a tension film removing device provided with a film removing means for rupturing the tension film of the liquid concentrate formed between the fingers of the glove type while being extracted from the liquid concentrate by the glove film forming device. Is provided.

[0010]

According to the above high voltage rubber gloves manufacturing method and manufacturing equipment, the glove mold is automatically dipped and pulled out by using the glove film forming device, and then attached to the surface of the glove film by the stock solution shaking device. Since the stock solution is shaken off and the glove type is automatically carried into the dryer by the glove type conveying device, it is possible to automate the work that requires promptness and a delicate feeling without touching human hands. It is possible to automatically produce uniform high-voltage rubber gloves, which can promote the export of manufacturing technology and the expansion of production volume, and improve the working environment.

In addition, by shaking off the undiluted solution by the undiluted solution shaving device from the lower level to the upper level, and further rapidly increasing the acceleration at the time of initial startup, it is possible to effectively shake off the droplets on the glove membrane surface. It is possible to manufacture high-voltage rubber gloves having a smooth surface and a uniform thickness.

Further, when the glove mold is pulled out from the stock solution by the tension film removing device, the tension film generated between the fingers due to the surface tension of the stock solution is pulled up from the stock solution during the pulling of the glove mold from the stock solution.
It can be ruptured and removed by a film removing means. As a result, when the tension film spontaneously bursts after the glove mold is pulled out from the stock solution, it is possible to prevent the stock solution remaining along the proximal end portion of the tension film from forming a recess, and to provide a high-voltage rubber glove without unevenness. It can be manufactured.
