Abstract

The invention discloses a safe chuck. The safe chuck comprises a transmission shaft and a pneumatic clamping mechanism, wherein the transmission shaft is supported on a rack through a bearing sleeve; a belt wheel is arranged at one end of the transmission shaft, and a positioning component for clamping an air expansion shaft is arranged at the other end of the transmission shaft; the pneumatic clamping mechanism is used for clamping the air expansion shaft; the positioning component comprises a fixed positioning block for positioning the air expansion shaft axially and a sliding ejection head for positioning the air expansion shaft axially; the pneumatic clamping mechanism comprises a clamping air chamber for clamping the air expansion shaft, a loosening air chamber for loosening the air expansion shaft and a clamping positioning block for clamping and positioning the air expansion shaft in the radial direction. The safe chuck has the characteristics of simple structure, flexibility in operation, convenience for mounting and dismounting the air expansion shaft, firmness in clamping, and safety and reliability; the safe chuck is provided with a protection structure for preventing incorrect operation; and meanwhile, the safe chuck further has the characteristics of high power transmission efficiency and the like.

Description

Technical field [0001] The invention relates to an expansion and tightening device that is convenient for changing the winding and reeling shaft, and is used for a winding chuck expansion and tightening device that is convenient for disassembly of a winding film and a plastic sheet production line. Background technique [0002] At present, the winding shaft chuck expansion device of the traditional production winding machine is inconvenient to disassemble and change the roll during the production process, the roll change time is long, and the expansion device is not reliable, which affects the accuracy of the winding and cannot meet the production needs of the entire production line. , Reducing production efficiency, and there are potential safety hazards. Summary of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a rewinding safety chuck expansion and tightening device with simple structure, convenient disassembl...
