Power dragging apparatus

Abstract

The invention relates to a power driven apparatus used for replacing corrugated rollers in a single-sided corrugated machine, comprising a screw mandrel 9, a nut 8, a deflecting ring 7, a dragging pinshaft6, a friction plate 10, a pressing block 5, a spring 4, a pressure adjusting nut 3, a spring support 1, a front guide strip 12, a rear guide strip 13, a support 1 and position control switches 11. The invention is characterized in that: the screw mandrel is arranged on the support by supporting; the deflecting ring is connected with the nut; the dragging pin shaft is vertically arranged on the deflecting ring; the spring support is sleeved on the screw mandrel; threads are arranged on the excircle of the spring support; the pressure adjusting nut is screwed on the excircle of the springsupport; the pressing block is sleeved on the screw mandrel; the friction plate is fixed on an inner end face of the pressing block through bolts; the spring is arranged between the pressure adjustingnut and the pressing block; the guide strips are respectively arranged on both sides of the screw mandrel to restrict the nut and the deflecting ring to rotate along with the screw mandrel; the position control switches are arranged on both ends of the screw mandrel and indicate that dragged components reach designated positions. The invention has the advantages of capability of accurately sending the dragged components to the designated positions, and automatic release of relationship with the dragged components.

Description

technical field [0001] The invention relates to a mechanical device, specifically a power drag device. Background technique [0002] The quick replacement of the corrugating roller parts of the single-sided corrugating machine can enable a machine to realize multiple flute type conversions, thereby expanding its application range and improving output value and economic benefits. The corrugating roller is a huge and core part on the single-sided corrugating machine, which has strict position requirements, and the replacement work is not done by manpower, which requires corresponding mechanical devices to send it into the exact position of the machine and push it out of the machine. Its easy to evacuate. [0003] The traditional driving device uses a motor, an air motor or a hydraulic motor to drive the dragged corrugating roll parts through a gear box and a rack and pinion pair. Since the rack and pinions are always in meshing state, it is inconvenient to evacuate the replac...

[0003] The traditional driving device uses a motor, an air motor or a hydraulic motor to drive the dragged corrugating roll parts through a gear box and a rack and pinion pair. Since the rack and pinions are always in meshing state, it is inconvenient to evacuate the replaced corrugating roll parts. Need to add other mechanical parts, complex structure, difficult operation, long time required for roll change
