Manufacturing method of PVC glove production line with good environmental protection

- Sep 28, 2020-

【Background technique】

PVC gloves are glove products produced with polyvinyl chloride as the main raw material. The main raw materials used are PVC paste resin, plasticizers, viscosity reducers, heat stabilizers, colorants and fillers, etc. The gloves made have good antistatic properties. It is suitable for semiconductor processing, food processing, sales and other industries.

The production process of PVC gloves includes the following steps: I) fully agitate and mix the raw materials according to a certain ratio, obtain the material liquid after filtration treatment, and transfer the material liquid into the trough; 2) the hand mold enters the trough dipping material; 3) Dip the hand mold for drip treatment; 4) After dripping, the hand mold is put into the oven for plasticization; 5) The plasticized hand mold is dipped in the polyurethane tank and dried; 6) The dried glove The blank is subjected to lip curling treatment; 7) the glove blank is removed from the hand mold to obtain the finished PVC glove; 8) inspection, rejecting unqualified products; 9) packaging and storing.

During use, it was found that the plasticized glove blank output from the oven will continue to emit smoke and pollute the workshop environment due to the continuous high temperature on the surface during subsequent operation; when the surface temperature of the glove blank is high, corresponding selection is required PU glue that can withstand higher temperatures, and the higher the temperature that PU glue can withstand, the higher its price, which increases production costs.

Latex glove dipping machine

[Content of the invention]


The purpose of the utility model is to overcome the shortcomings in the prior art and provide a PVC production line with good environmental protection. The production line sprays and cools the wrist of the hand model that has just been output from the oven, and the hand model is released after the temperature drops sharply. The outgoing flue gas is absorbed by the fume hood and discharged outside, thereby reducing the environmental pollution of the workshop caused by the disorderly discharge of the flue gas. The technical solution adopted is: a PVC glove production line with good environmental protection, including a circular track and support A drive chain on the track and a plurality of hand mold assemblies connected to the drive chain, the hand mold assembly includes a hand mold, and the production line further includes a dip part through which the hand mold passes in turn and The drying part is characterized in that: the production line also includes a spraying and fume elimination system, the spraying and fume elimination system includes a water storage tank, a spray head connected with the water storage tank pipeline, and the drying part The processed hand mold is sprayed and cooled by the spray head, a smoke collecting hood is arranged above the spray head, and a water collecting port is arranged below the hand mold. The circulation sprayed from the spray head The water is collected into the water collection tank from the water collection port, and the water collection tank is connected with the water storage tank pipeline.

The technical feature of the utility model is that the connecting pipe between the water collection tank and the water storage tank is also provided with a water pump.

The technical feature of the utility model is also: a filter is also arranged between the water storage tank and the spray head.

The technical feature of the utility model is also: the hand model includes a hand model wrist, and the circulating water sprayed from the spray head is directed toward the hand model wrist.

The utility model also has technical features: the glove production line also includes a PU glue adding and drying part, a lip curling part, a demolding part, and a hand mold cleaning part. The hand mold after being cleaned by the hand mold cleaning part enters the factory. The dipping part is dipping.

The beneficial effect of the utility model is that: the production line is equipped with a spray smoke elimination system after the drying part, and the temperature of the hand mold is drastically reduced by spray cooling, so that the smoke is released in a concentrated manner, and the released smoke The fume collection hood is discharged outside, thereby improving the workshop environment; because the temperature of the hand mold is reduced, PU glue with lower temperature tolerance can be selected, which reduces the production cost; this production line has the advantages of good environmental protection and low production cost.

【Patent Abstract】

An environmentally friendly PVC glove production line, including a circular track, a transmission chain supported on the track, and multiple hand mold components connected to the transmission chain. The hand mold components include hand molds, and the production line also includes hand molds Passing through the dipping part and the drying part in turn, the production line also includes a spray smoke elimination system. The spray smoke elimination system includes a water storage tank, a sprinkler head connected to the water tank pipeline, and a hand model after the drying part. The sprinkler head is used to spray and cool the temperature. There is a smoke collecting hood above the sprinkler head, and a water collecting port under the hand mold. The circulating water sprayed from the sprinkler head is collected from the water collecting port to the water collecting tank. Water storage tank pipeline connection. This production line has the advantages of good environmental protection and low production cost.
