Abstract

The invention provides a method and a device for measuring pulling-out smoothness of push-in type tubular fabrics. The device for measuring pulling-out smoothness of the push-in type tubular fabrics is characterized by comprising a heat pipe mechanism, a plunger mechanism, a plunger push-in mechanism and a fixing mechanism. The plunger push-in mechanism comprises a step motor, a transmission mechanism, a left screw rod and a right screw rod, and a middle beam sleeves the left screw rod and the right screw rod. The heat pipe mechanism comprises a heat pipe, press sensors and a T-shaped connector, and the tubular fabrics can sleeve the outer wall of the heat pipe. The step motor is capable of driving the left screw rod and the right screw rod to rotate synchronously through the transmission mechanism to further drive the middle beam to move upwards, so that the tubular fabrics which sleeve the outer wall of the heat pipe can be drawn back and pushed into the heat pipe. The method and the device can be used for measuring pulling-out smoothness of the tubular fabrics sleeving the heat pipe under different temperature conditions, and structural simplicity, mechanism delicacy and simplicity, convenience and quickness in measurement are realized.

Description

technical field [0001] The invention belongs to the technical field of textile precision measuring instruments, and relates to a device and a method for measuring the smoothness of drawing of a top-entry tubular fabric sleeved on the wall of a heat pipe, especially the sleeved tubular fabric used under different temperature conditions.
