AI Technical Summary
Existing film stretching equipment has a lag in detecting film breakage, which causes the film to wrap around the rollers and damage the equipment. It cannot effectively avoid roller deformation and damage.
By employing a contact-type push-button switch sensor, the system detects changes in roller diameter and transmits signals in a timely manner through a set gap range, enabling rapid shutdown of the equipment and reducing equipment damage.
It effectively reduces equipment damage, extends the service life of stretching rollers, reduces equipment lag, and improves equipment protection.

Abstract
Claims
1. A pull-through packer probe structure mounted on a draw roll frame, characterized by: The device includes a mounting beam and a contact push-button switch sensor. The mounting beam is positioned on one side of the stretching roller and parallel to it. A mounting groove is recessed along the length of the side of the mounting beam facing away from the stretching roller, and a motor is mounted at one end of the mounting groove. A reciprocating screw, parallel to the stretching roller and connected to the motor via a coupling, is rotatably mounted inside the mounting groove. A slider is threaded onto the reciprocating screw. A guide groove communicating with the mounting groove is formed along the length of the side of the mounting beam facing the stretching roller. A connecting block, aligned with the guide groove, is connected to the slider. The end of the connecting block extends through the guide groove to the outside of the mounting groove and is connected to a mounting base. The contact push-button switch sensor is mounted on the mounting base and faces the stretching roller.
2. The pull-through roll probe structure of claim 1, wherein: The wiring of the contact push button switch sensor is electrically connected to the motor controller of the drive motor of the stretching roller. A cable chain is installed between the mounting base and the mounting beam, and the wiring is located inside the cable chain.
3. The pull-through roll probe structure of claim 1, wherein: The mounting slot has recessed track grooves on its opposite side walls. Guide wheels are mounted on the two sides of the slider that are facing the track grooves via axles. The axles are perpendicular to the sliding direction of the slider. The guide wheels roll in cooperation with the track grooves and roll in the sliding direction of the slider.
4. The longitudinal tension roll probe structure according to claim 1, characterized in that: One end of the mounting beam is vertically connected to the stretching roller frame via a connecting seat and bolts.
5. The pull-through roll probe structure of claim 4, wherein: A support rod connects the end of the mounting beam away from the connecting seat to the stretching roller frame.
