Novel safe maintenance-free oil heating roller body

Abstract

The invention relates to a novel safe maintenance-free oil heating roller body which comprises two shaft head, namely a left shaft head and a right shaft head, and a middle roller shell, wherein a liner is arranged in the middle roller shell; a ring-shaped cavity between the outer surface of the liner and the roller shell is a heating cavity allowing heat transfer oil to flow through; uniform heating on the roller shell is realized by a thermal balancing mechanism and a temperature compensation oil tube which are arranged on the outer surface of the liner, so that rapid heating of the roller body is ensured and the temperature of the roller face is kept uniform; by oil throwing blades arranged at the end parts of the shaft heads, oil leakage protection mechanisms on the outer walls of oil delivery pipes as well as oil receiving tanks and oil conduits, which are arranged at the sealed end covers, the sealing requirement is sufficiently ensured, the heat transfer oil is prevented from being leaked and the maintenance-free requirement is met; the shaft heads are sufficiently cooled by heat insulation mechanisms arranged on the outer walls of the oil delivery pipes and radiating fins arranged on the outer surfaces of the shaft heads, so that heat insulation and heat dissipation can be effectively carried out and damage to sealing parts is reduced, the service lives of bearings at both ends of each shaft heads are ensured.

Description

technical field [0001] The invention relates to a textile machinery equipment, in particular to a novel oil heating roller body which is safe and maintenance-free. Background technique [0002] The ironing rolls on the market today are basically electric heating rolls, and the oil heating rolls all use indirect heat transfer, the energy utilization rate is low, the temperature of the roll surface cannot meet the use requirements, and the oil outlet pressure of the boiler room and The oil outlet temperature has very high requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a new type of oil heating roller body with high efficiency, no leakage, safety and maintenance free, aiming at the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following technical scheme, a new type of safe and maintenance-free oil heating roller body, inclu...
