AI Technical Summary

Technical Problem

In the current PVC sheet production process, if the surface of the traction roller is scratched or sticky with material, the machine needs to be stopped for repair, which affects production efficiency.

Method used

The guide roller is used to assist in tensioning the sheet. The speed is reduced during the repair of the traction roller, and the sheet is tensioned by the guide roller. After the repair, the sheet is reset. There is no need to disassemble the sheet or stop the machine. The speed of the traction roller is adjusted by the servo motor and the lead screw to coordinate with the rotation of the guide roller.

Benefits of technology

This technology enables the sheet to maintain tension during the traction roller repair process, avoiding downtime, improving production efficiency, and reducing the impact of roller damage on processing efficiency.

Abstract

The application relates to a PVC sheet traction machine, belonging to the field of traction machines, which comprises a rack, a plurality of traction rollers rotatably connected to the rack, sheet tensioned on the outer periphery of the traction rollers, a plurality of traction rollers lifting and slidingly connected to the rack, a plurality of driving elements on the rack, the driving elements driving corresponding traction rollers to lift, a guide roller rotatably connected to the rack, a guide groove being formed on the guide roller and used for the sheet to pass through, and a positioning element arranged on the rack and used for positioning the guide roller. The guide roller assists in tensioning the sheet during traction roller repair, so that the sheet can still be forwarded at a slow speed, the traction roller is directly reset after repair, the sheet does not need to be disassembled and the machine does not need to be stopped, and the influence of traction roller damage on processing efficiency is reduced.
