- Dec 03, 2020-

Background technique:


PVC gloves are disposable fast-moving consumer goods, with the advantages of comfortable wearing, good sealing, acid and alkali resistance, no skin allergies, and anti-static properties. It is widely used in many fields such as medical and health, biopharmaceutical, electronic product processing, fine chemical industry, food processing, paint coating, printing and dyeing.


The production process of pvc gloves is as follows: first, various main raw materials and additives are mixed in a special container according to a certain proportion to form an emulsion; then after filtering, vacuuming, and standing, the mixture is sent to the production line with a pump Then the hand molds on the assembly line automatically enter the dipping tank, and the hand molds that adhere to the emulsion come out of the dipping tank in turn, and the excess emulsion drips down while traveling; the dripping liquid returns to the dipping tank through the collection tank In the tank; after dripping the excess emulsion, the hand mold moves into the oven with the production line. The temperature of the oven is controlled at 230-250°C. Under this condition, the emulsion on the hand mold is cured and formed; the hand mold coming out of the oven is naturally cooled, Lip rolling, powder dipping, pre-removal and other processes, wait for the gloves to be removed from the hand mold, and the hand mold will travel to the dipping tank again; the removed pvc gloves will be put into storage after powder removal, inspection and packaging.


The hand mold on the existing production line is fixed on the hand mold base, and the hand mold base is connected with the conveyor chain on the track through a pin shaft. When the chain moves, the hand mold base moves with it, thereby driving the hand mold to move. In this process, when the hand mold leaves the dipping tank, the adhered pvc slurry can only drip under its own gravity, which will cause The PVC slurry on the hand mold is not uniformly coated, and the weight of the adhered PVC slurry is unstable, which affects the quality of the PVC gloves produced.
