Automatic locking device for winding arm of station type slitting machine

Abstract

The invention discloses an automatic locking device for a winding arm of a station type slitting machine. The winding arm is mounted on a sliding block. The movement of the winding arm is generated through the relative movement of a linear guide rail and the sliding block. The linear guide rail is mounted on a beam, and a fine tooth rack is mounted in parallel to the linear guide rail. A tooth block is mounted on the winding arm. An air cylinder is used as a power source of locking, and the tooth block mounted on an opening / closing air cylinder on the winding arm and the rack mounted on the winding beam are used as an execution mechanism. Meanwhile a magnetic switch for stroke in-place detection of the air cylinder is mounted on the locking air cylinder, an the air cylinder as a power source pushes the tooth block to be engaged with the rack when the winding arm is in the locked state; if the tooth block is in touch with the tip of the rack, the magnetic switch on the locking air cylinder does not operate, the winding arm does not operate as well, and the magnetic switch operates only when the tooth block and the rack are engaged; at this moment, the winding arm is in the operating state, no matter the winding arm moves to which position of the beam, teeth and the rack can be locked; and whether the winding arm is in the operating state or not is informed by the magnetic switch.

Description

technical field [0001] The invention relates to a locking device, in particular to an automatic locking device for a slitting machine after the winding arm moves. Background technique [0002] Before this invention, the rewinding arm of the slitter was locked, and there were two types of stations at home and abroad: automatic and manual. The foreign automatic state is completed by the servo motor acceleration and deceleration device and the locking device. The servo motor and deceleration device are used to move the rewinding arm to open and close, and the locking device is used to lock the rewinding arm when it moves arbitrarily or when opening and closing. The above two cooperate to complete the locking and are indispensable. At home and abroad, manual locking is done by tightening the nuts together or stuck with a manual wrench, and the opening and closing are all done by the cylinder (when the cylinder is open, it is in the unloading state of the rewinding arm, and when...

Problems solved by technology

In reality, the manual locking of the rewinding arm device of the slitter is the vast majority, and the automatic locking only accounts for a small part of the foreign slitting machine entering the Chinese market. At present, the station type slitting machine is in the Chinese market. Domestic production accounts for the vast majority, foreign imports only account for a small part, and there is no automatic locking device in the domestic slitting machine.
