Inflatable shaft

The air expansion shaft reeling is to fix the multi winding material cylinder core on one air expansion shaft, drive the reeling shaft with a torque motor or drive the reeling shaft with a combination of motor and magnetic particle clutch, so that the linear speed of the material surface on the reeling shaft is synchronized with the host machine to complete the multi winding function. This method has the advantages of simple structure, low cost and convenient unloading. It is suitable for coiling materials with smaller thickness error, fewer coils and larger tension, while it is not suitable for materials with larger thickness error, more coils and smaller tension. In serious cases, it cannot be coiled.

In serious cases, it cannot be coiled. A rolling slip shaft structure, which has at least one locating ring, at least one shaft seat and one shaft rod, wherein, a plurality of embedded holes are formed at the periphery of each locating ring, and at least one embedded hole is formed for each embedded hole, each embedded hole is sliding with a crown block with class edge, and the bottom surface of each crown block is formed with a convex part corresponding to the shape of embedded hole, and a positioning steel ball slightly protruding from the surface of the locating ring is respectively arranged between each embedded hole, The lower section of each positioning steel ball can be locked downward and extended into the shaft seat, and
The outer edge of the shaft seat is formed with a number of jacking surfaces corresponding to the jacking block, and each jacking surface can be shrunk inward to the surface of the positioning ring to form a wall surface respectively. The shaft seat is provided with a jack hole at the bottom of each jacking surface close to the wall surface, each jack hole contains a strong magnet relative to the jacking block, and each shaft seat is provided with a guide groove at each jacking surface corresponding to each positioning steel ball, and the shaft rod penetrates the center of each shaft seat, Each top guide surface pushes against the bulge of each top guide block; The utility model is characterized in that: a plurality of grooves are arranged axially at equal intervals around the periphery of the shaft rod in a flat form, and are connected with the front and rear ends of the shaft rod, and each groove system has an injection port connected with the end face of the shaft rod; A number of rubber tubes are respectively contained in grooves, and each rubber tube is respectively provided with a valve at the corresponding injection port, while each rubber tube is respectively provided with a tightening piece at the front end close to the shaft rod, and each rubber tube is respectively provided with a fastening piece at the rear end close to the shaft rod. In addition, each tightening piece is additionally provided with a number of separately raised tightening sections at the distance close to the front end of the shaft rod; A plurality of slip blocks are arranged in parallel at the position corresponding to the axle seat of the rubber tube, and each slip block system is in a convex shape; The two sleeves are respectively equipped with a plurality of screws to tighten the forcing pieces and the fastening pieces relative to each forcing piece and the fastening piece.
