Loop forming head automatic reset device

Abstract

The invention discloses a looping head automatic reset device, comprising a looping head, wherein a coronary positioning ring is fixedly arranged on the looping head; a plurality of tooth-shaped grooves are formed in the end surface of the coronary positioning ring at equal distances; the coronary positioning ring is subjected to circumferential positioning through the tooth-shaped grooves by using a positioning pin; and the number of the tooth-shaped grooves formed in the end surface of the coronary positioning ring is equal to that of circumferentially distributed gaps of the looping head. The positioning pin is a pin shaft provided with a roller which is a bearing. The looping head automatic reset device can ensure that the looping head can be subjected to fixed point stop and automatic reset, and the looping head automatic reset device has the advantages of accurate stop position and reasonable structural design.

Description

technical field [0001] The invention relates to a cable winding device, in particular to a positioning device used in the cable winding device to automatically reset and stop at a fixed point for the loop forming head. Background technique [0002] As a device for coiling cables into rolls, cable winding machines are indispensable in every cable production enterprise, and coiling heads used to coil cables in cable winding machines are indispensable. missing parts. In order to match the corresponding process in the cable winding machine, there are usually a number of axial slits evenly distributed on the cylindrical ring surface of the coil forming head. When the machine is in motion, the loop forming head is driven by the sliding shaft connected to it, and the thread end will be pressed in the gap during its downward pressure process, and the gap becomes smaller when the loop forming head rises after the coil is completed.

Problems solved by technology

In order to match the corresponding process in the cable winding machine, there are usually a number of axial slits evenly distributed on the cylindrical ring surface of the coil forming head. When the machine is in motion, the loop forming head is driven by the sliding shaft connected to it, and the thread end will be pressed in the gap during its downward pressure process, and the gap becomes smaller when the loop forming head rises after the coil is completed. It will bring up the end of the thread, thereby messing up the coil, causing quality defects in the coil, and in severe cases, it will produce waste products

On the cable winding machine, the coiling head is driven by the rotating power disc through extrusion friction. After each coiling is completed, the coiling head is driven by the slide bar and disengaged from the rotating power disc. Automatic reset and limit device when the head is stopped, the stop position of the looping head is very random, and the phenomenon that the gap is just facing the thread end stops from time to time, which will inevitably cause considerable trouble to the production, and the quality and output of the product will be affected.
