Monitoring system for zipper tooth discharging machine

The utility model discloses a monitoring system for a zipper tooth discharging machine. The monitoring system comprises a supporting vertical plate, a supporting transverse plate, a movable touch plate, a limit switch and a ball spring, wherein the supporting transverse plate is mounted on the right side surface of the supporting vertical plate; grooves are formed in the top surface of the supporting transverse plate; the movable touch plate is mounted at the middle part of the right side surface of the supporting vertical plate through a screw; a concave hole is formed in the upper part of the right side surface of the supporting vertical plate; a threaded through hole is formed in the upper part of the movable touch plate in a left-and-right direction; the ball spring is mounted inside the threaded hole; the limit switch is mounted on the right side of the supporting vertical plate in front of the movable touch plate. Through arrangement of the movable touch plate, the limit switch and the like, whether a cloth band has joints or other defects is monitored, and in case of a defect, the defect is immediately sensed to a controller and the zipper tooth discharging machine stops and gives an alarm, so that the problems that in production of the existing zipper tooth-discharging injection-moulding machine, mechanical failures and rejected products are caused by the joints of the cloth band are solved.
