AI Technical Summary

Technical Problem

In the existing technology, when the heating wire is wound around the outer wall of the conveying pipe, although heat can be transferred through heat conduction, heat is also dissipated outwards at the same time, resulting in heat loss and affecting the heating effect.

Method used

Design a heating component for pretreatment of rubber materials. It adopts a rotating shaft and spiral blade structure with built-in heating wire. The rotating shaft is driven by a motor to transport the rubber material, and a temperature controller is used to control the heating wire to heat the rotating shaft and spiral blade to avoid heat being directly conducted to the outside of the conveying pipe. An insulation sleeve is installed on the outside to reduce heat loss.

Benefits of technology

This method achieves uniform heating of the rubber compound, prevents heat loss, improves heating efficiency and insulation performance, and ensures stable delivery of the rubber compound.

Abstract

The utility model relates to the technical field of sizing material heating, and discloses a warming and heating assembly for sizing material heating pretreatment, which comprises a conveying pipe, one end of the conveying pipe is connected with a sizing material inlet pipe, the other end of the conveying pipe is connected with a sizing material outlet pipe, and one end of the conveying pipe adjacent to the sizing material inlet pipe is provided with a motor. A temperature controller is installed at the end, close to the glue outlet pipe, of the conveying pipe, a rotating shaft is arranged in the conveying pipe, spiral blades are installed on the outer wall of the rotating shaft, a through hole is formed in the end, facing the temperature controller, of the rotating shaft, and a heating wire is inserted into the through hole. When glue is injected into the glue inlet pipe, the motor drives the rotating shaft and the spiral blade to convey the glue in the conveying pipe, the temperature controller controls the heating wire to work, the heating wire heats the rotating shaft and the spiral blade, and the spiral blade on the rotating shaft can serve as a heat conduction fin to evenly heat the glue in the conveying pipe. As the heating wire is arranged in the conveying pipe, heat of the heating wire is conducted into the conveying pipe from the rotating shaft.
