[0002] PVC gloves are gloves made of polyvinyl chloride as the main raw material. PVC gloves are also resistant to weak acids and alkalis, and are suitable for production processes such as semiconductors, liquid crystals and hard drives.

[0003] For example, the Chinese patent with the publication number CN213829973U discloses a track changing device for a hand mold seat of a PVC glove production line, including a turntable, a horizontal rail is horizontally arranged in the middle of the top of the turntable, a vertical rail is vertically arranged in the middle of the top of the turntable, four support frames are equidistantly arranged around the turntable and tracks are arranged on the support frames, a fixed groove is arranged below the turntable, a servo motor is arranged in the fixed groove, and the rotating shaft of the servo motor is fixedly connected to the middle of the bottom end of the turntable. In the utility model, the servo motor is controlled to rotate the turntable to realize the multi-directional rapid track change of the device. There is no need to stop the equipment during the track change, which does not affect the processing and production efficiency. The support arm and the guide roller are used to cooperate with the clamping ball on the edge of the turntable below the horizontal rail and the vertical rail to engage with the groove on the support frame below the docking track to realize the precise connection between the horizontal rail and the vertical rail and the track, so that the slider will be smoother and will not be stuck when passing through the connection point, which is worthy of vigorous promotion.
