[0002] The production of PVC gloves needs to strictly control the quality of raw materials, including the proportioning of additives such as polyvinyl chloride resin. If the particle size of the raw material does not meet the requirements, it may cause problems such as uneven thickness and decreased elasticity of the gloves. Therefore, the premixing and screening device can automatically screen out raw material particles that do not meet the size requirements through the design of the vibrating screen mechanism and the guide plate, ensuring uniform mixing.
