Description

Technical Field

[0001] The utility model relates to the field of PVC glove production, in particular to a raw material feeding device for PVC glove production. Background Art

[0002] PVC gloves are made of polyvinyl chloride through a special process. The gloves are free of allergens, powder-free, low in dust, low in ions, and free of plasticizers, esters, silicone oils and other ingredients. They have strong chemical resistance, good flexibility and touch, are easy and comfortable to wear, have anti-static properties, and can be used in a dust-free environment. The production process of PVC gloves generally includes steps such as batching, grinding, mixing, dipping, drying, crimping and demoulding, and vulcanization.

[0003] The basic raw materials of PVC gloves are: PVC paste resin, plasticizer DOPDINP adhesive (solvent oil), heat stabilizer, colorant, filler. Among them, PVC paste resin is a bagged powder, which needs to be added to the reaction tube for mixing and stirring reaction during the production and processing. Most of this process is done manually by staff, who carry the packaging bag in advance and dock it at the filling port, and then cut a hole with a blade so that the PVC paste resin powder falls into the reaction tube for subsequent stirring and mixing. Based on this, the existing manual operation feeding efficiency is very slow, and wastes manpower to increase the workload of supervisors, and the overall practical effect is not good.

[0022] Based on the above structure, when the utility model is in use, the staff starts the motor 403 through the external switch and adjusts the appropriate speed. The motor 403 drives the threaded rod 401 at the power end to rotate. The threaded rod 401 thread-driven slider 6 slides horizontally along the slide groove 5 with the cooperation of the limit rod 402, driving the conveying plate 7 at its upper end to move horizontally.
