Roller for energy-saving constant-temperature oil heating mangle

Abstract

The invention discloses a roller for an energy-saving constant-temperature oil heating mangle, which comprises a roller body; spindle noses are fixed at two ends of the roller body; the roller body is provided with a roller shell; an oil inlet end cap and an oil outlet end cap are respectively fixed at two ends of the roller shell; an oil inlet spindle nose is arranged on the oil inlet end cap; an oil outlet spindle nose is arranged on the oil outlet end cap; a cylindrical inner container is arranged in the roller shell; an oil inlet cavity is arranged between the oil inlet end cap and the inner container; an oil outlet cavity is arranged between the oil outlet end cap and the inner container; an annular cavity between the cylindrical surface of the inner container and the inner wall of the roller shell forms an oil passage; a plurality of spiral flow guide grooves are arranged on the cylindrical surface of the inner container; the flow guide grooves are formed by the diversion of spiral flow guide fins on the cylindrical surface of the inner container; the rotation angle of the flow guide fins from the oil inlet end to the oil outlet end of the oil passage is 160-200 degrees; the distance between the cylindrical surface of the inner container and the inner wall of the roller shell is 10-12mm; and the height of each flow guide fin is 5-6mm. The inner container is provided with an exhaust pipe which is communicated with the outside. By using the heat guide oil to transfer heat, the roller is even in heating and accurate in temperature regulation and control.

Description

technical field [0001] The invention relates to leather processing equipment, in particular to an energy-saving constant-temperature oil heating ironer roller. Background technique [0002] Ironing machine rollers used to be heated by steam as the medium, and enterprises must be equipped with steam boilers. Moreover, with the popularization of new high-temperature resistant leather chemicals, the ironing temperature can reach up to 140 ° C. If steam heating is used , Higher steam pressure is required, and the enterprise must also obtain a pressure vessel manufacturing license. Therefore, steam heating rollers will be gradually eliminated. [0003] The ministerial standard for roller ironing machines (QB / T 2008—1994) stipulates that within a working width range, the temperature difference of the ironing rollers is within 10 degrees to qualify. Since the standard was issued in 1994, leather chemical raw materials have developed rapidly in the past ten years, and the leather ...

Problems solved by technology

[0004] The ironing roller can also be designed so that the electric heating tube is directly installed in the ironing roller, but the life of the electric heating tube is not too long and it is difficult to replace
