Problems solved by technology
For the processing of double-layer or multi-layer gloves, the current technical methods include manual brushing, dipping, and spraying. These methods are easy to operate and low in production cost, but their disadvantages are that the coated rubber Poor layer adhesion, uneven rubber thickness, short service life of gloves, low production efficiency, poor protective effect, etc.; the application of injection molding processing methods commonly used in industry in gloves coating film has not yet been reported

Embodiment
[0008] In this embodiment, fiber gloves are coated with a rubber film layer by means of rubber mechanical injection molding equipment. First, the fiber gloves to be coated are evenly wrapped on the human hand mold body, and then the mold body that has been wrapped is placed on the same surface as the mold body. In the mold body box matched with the mold body, keep the fiber smooth surface on the front side of the mold body and the corresponding surface of the mold body box to form a 0.1-0.5mm hand cavity type gap layer, and the reverse side of the mold body hand or the back of the hand from the fingers The smooth surface of the glove fiber whose thickness gradually decreases to zero in the direction from the tip to the palm of the hand forms a 0.1-0.5mm cavity-type gap layer on the back of the hand with the corresponding surface of the mold body box; the area of the cavity-type gap layer on the back of the hand is greater than 0; close the mold box Finally, use an injection m...

Abstract
The invention belongs to the technical field of labor protection product processing and relates to an injection method of rubber film layers on surfaces of cellulosic gloves, which comprises: wearing the cellulosic gloves to be coated on hand mold bodies uniformly, and placing the hand mold bodies with the cellulosic gloves in mold body boxes matched with the mold bodies, wherein 0.1 to 0.5 millimeter hand back cavity type clearance layers are formed between the cellulosic surfaces of the gloves and the corresponding surfaces of the mold body boxes; closing and sealing the mold boxes, filling up the clearance layers with liquid rubber by an injection machine through an injection hole, cooling the liquid rubber and making the liquid rubber adhere firmly; and opening the mold boxes and taking down the gloves worn on the hand mold bodies, wherein the gloves are formal products for sale. The coating rate of the rubber film layers on the palm sides of the cellulosic gloves is 100 percent, and the coating rate of the rubber film on the hand back sides of the cellulosic gloves is 0 to 100 percent; and the process principle is simple, the processing cost is low, rubber raw material is saved, the quality of the products is high, and the service life of the products is long, the labor protection effect is desirable. Thus, the method can replace the conventional processing method.
Description
Technical field: [0001] The invention belongs to the technical field of labor protection products processing, and relates to a rubber film layer injection molding processing method for protecting the surface of fibrous gloves, so that a layer of rubber film layer is formed on the surface of the linear glove to play protective functions such as anti-fouling, waterproof, anti-corrosion, anti-skid, etc. . Background technique: [0002] With the rapid development of the industrial economy, the processing and manufacturing of industrial products is also moving towards scientific, automated and humanized directions. In various fields of industrial production, there are many fields with harsh production environment and serious pollution, especially in chemical industry, petroleum, urban sewage treatment, seawater product processing, machinery manufacturing, industrial hydrochloric acid production and other occasions. In automated enterprises, cases of manual operation can be seen ...
