Aligning protection device for large-volume center roller flange

Abstract

The invention relates to an aligning protection device for a large-volume center roller flange. The aligning protection device comprises a frame, an inflatable roller and inflatable-roller drive components. The inflatable-roller drive components are arranged at two ends of the inflatable roller, and comprise safety chucks, central shafts and bearing blocks; the bearing blocks are arranged on the frame, and the central shafts are rotatably supported on the bearing blocks; one end of the inflatable roller is detachably connected with the safety chucks; each safety chuck is hinged to one end of the corresponding central shaft. The aligning protection device is characterized in that the aligning protection device further comprises alignment mechanisms, and each alignment mechanism comprise anencoder, an encoder connecting shaft and an encoder mounting support; the encoder mounting supports are arranged on the outer sides of the central shafts and fixedly connected with the frame, each encoder is fixedly connected to one end of the corresponding encoder connecting shaft, the encoders are located on the outer sides of the encoder mounting supports, and the other ends of the encoder connecting shafts are fixedly connected with the central shafts. The aligning protection device has the advantages of simple structure and capability of aligning the safety chucks.

Description

technical field [0001] The invention relates to an alignment protection device, in particular to an alignment protection device for a flange plate of a center roll of a large roll. Background technique [0002] Existing large-scale rolling equipment is to make the fabric pass through the transition roller, tension roller and friction roller in turn, and finally wind the fabric into a cloth roll by the air roller. In the prior art, the two ends of the air-expanding roller are installed on the safety chuck, and after the winding is completed, the safety chuck is opened, so that the air-expanding roller falls from the safety chuck and is pushed onto the cloth drop frame , during this process, the opening of the central shaft connected to the safety chuck is turned to the upper side to open the safety chuck. In the prior art, the operator observes with the naked eye whether the opening of the central shaft is turned to the upper side, often There is a certain error, so that the...

In the prior art, the two ends of the air-expanding roller are installed on the safety chuck, and after the winding is completed, the safety chuck is opened, so that the air-expanding roller falls from the safety chuck and is pushed onto the cloth drop frame , during this process, the opening of the central shaft connected to the safety chuck is turned to the upper side to open the safety chuck. In the prior art, the operator observes with the naked eye whether the opening of the central shaft is turned to the upper side, often There is a certain error, so that the opening of the central shaft does not turn to the top, if the safety chuck is opened in this case, the air roller will be stuck and the air roller will be damaged
