Safe and maintenance-free oil-heated roll body

Abstract

A novel safe maintenance-free oil heating roller body comprises left and right shaft heads (9) and a middle roller shell (11). A linear (12) is disposed in the middle roller shell (11). A ring-shaped cavity between an outer surface of the linear (12) and the roller shell (11) is a heating cavity allowing heat conduction oil to flow through. Uniform heating on the roller shell (11) is realized by a thermal balancing mechanism and a temperature compensation oil tube (17) that are arranged on the outer surface of the linear (12), so that rapid heating of the roller body is ensured and the temperature of a roller face is maintained uniform. By using oil throwing blades (10) arranged at end parts of the shaft heads (9), oil leakage protection mechanisms on outer walls of oil delivery pipes (4), and oil receiving tanks (13) and oil conduits (2) that are arranged at sealed end covers, a sealing requirement is sufficiently ensured, heat conduction oil is prevented from being leaked and a maintenance-free requirement is met; the shaft heads (9) are sufficiently cooled by heat insulation mechanisms arranged on outer walls of the oil delivery pipes and heat radiating fins arranged on outer surfaces of the shaft heads (9), so that heat insulation and heat dissipation can be effectively performed and damage to sealing parts is reduced, and therefore, service life of bearings at two ends of the shaft heads (9) is ensured.

Description

Technical field [0001] The invention relates to a textile machine equipment, in particular to a new type of safe and maintenance-free oil heating roller body. Background technique [0002] The ironing rollers on the market today are basically electrically heated roller bodies. All oil-heated roller bodies use indirect heat transfer methods. The energy efficiency is low, and the temperature of the roller surface does not meet the requirements for use. The oil outlet temperature has high requirements. Summary of the invention [0003] The technical problem to be solved by the present invention is to aim at the shortcomings of the prior art and propose a new type of oil heating roller body with high efficiency, no leakage, safety and maintenance-free. [0004] The technical problem to be solved by the present invention is achieved through the following technical solutions. A new type of safe and maintenance-free oil-heated roller body includes two left and right shaft heads and a midd...
