AI Technical Summary

Technical Problem

Existing plastic pipe drying equipment requires manual insertion and removal of pipes. The horizontal placement of the cylinder and the static hot air distribution result in insufficient stacking or rolling of pipes, leading to problems such as drying dead zones and moisture residue.

Method used

The conveyor belt and limiting components within the frame, along with the cylinder-driven push plate and diversion plate, form a stable positioning space. Combined with the tilting rotating cylinder and diversion components, a fan provides circulating hot air, achieving efficient tumbling and uniform heating of the pipes. Condensate is automatically discharged through a sloping water box.

Benefits of technology

It achieves high-precision positioning, uniform drying, and automated management of pipes, improving drying efficiency and quality, and avoiding pipe wear and moisture residue.

Abstract

This utility model discloses a plastic pipe drying device. The device effectively prevents pipe deviation during transport through a detachable limiting component on the transmission belt. The longitudinal and lateral coordinated sliding of the first and second push plates, driven by a cylinder, along with a sliding first baffle, forms a stable cuboid positioning space, ensuring precise constraint of the pipe before it enters the drying stage. An inclined cylinder, combined with a guide component featuring a trapezoidal arc inner wall covered with a polyurethane wear-resistant layer, efficiently guides the pipe forward while it rotates, driven by a motor and gears. The circulating hot drying air provided by the fan inside the casing significantly improves heating uniformity and drying efficiency, while minimizing wear on the pipe surface.
