Manufacturing method of automatic demoulding and grouping machine for PVC gloves

- Feb 04, 2021-

Background technique:

PVC gloves are typical plastic processed products with dipping process. Due to the characteristics of fast production cycle, light weight, softness and static electricity, its packaging automation has always been bottlenecked, and it is still a labor-intensive industry. The level of automation in my country's PVC glove production industry is generally low, especially in the glove packaging process, which mainly relies on manual tasks such as counting and grouping. Usually the packaging specifications of gloves are 25 pieces/group, 4 groups/box, that is 100 pieces/box. In order to ensure the consistency of the overall thickness of the gloves when packing, it is required that the finger ends and the cuff ends of the 4 groups of gloves in each box are placed alternately.

At present, the automatic demoulding technology of PVC gloves is divided into two types: full release and half release. The full-release automatic mold release machine completely removes the gloves from the hand mold, collects them, and then manually picks out, counts and groups the gloves; the semi-release automatic mold release machine removes the gloves from the hand mold. Pull up to the set position. After the operation is completed, the cuff end of the glove hangs down, and the finger end of the glove is still attached to the hand mold. The subsequent demolding, counting and grouping operations also need to be completed online manually. It can be seen that although the glove demolding technology is relatively mature, the subsequent glove counting and grouping work is still inseparable from manual operation, so it is a bottleneck to improve the automation level of the PVC glove production line. Within the scope of the applicant's search, no documents directly related to the PVC glove demolding and forming machine of the present invention have been found.
