High-flatness low-energy-consumption sector printing-dyeing drying drum

Abstract

The invention discloses a high-flatness low-energy-consumption sector printing-dyeing drying drum, comprising a left shaft head, a drum body, a left head, a right head, and a right shaft head; the drum body is a sector drum having the outer surface that has high middle and low ends along the axis; the drum body is fixedly connected between the left head and the right head; the left head and the right head are provided with circular grooves respectively; a dual-sector support device is arranged in the drum body. The high-flatness low-energy-consumption sector printing-dyeing drying drum is further characterized in that the drum body is a composite drum body including a seamless drum body inside and a stainless steel outer layer covering the outer wall of the seamless drum body; the outer side of each of the left head and the right head is provided with a retaining plate; one retaining plate and the circular groove of the left head form a sealed cavity, and the other retaining plate andthe circular groove of the right head also form a sealed cavity; the sealed cavities are filled with heat-insulating lining; the heat-insulating lining is made from any of composite magnesium silicateinsulation plates, rubber-plastic sponge, polyethylene foam and polystyrene foam. The high-flatness low-energy-consumption sector printing-dyeing drying drum has high structural strength and rigidity, can ensure that the surface of fabric is flat during use, can tolerate high temperature, and has low heat loss and low energy consumption.

Description

technical field [0001] The invention relates to the field of printing and dyeing machinery, in particular to a drying cylinder for printing and dyeing. Background technique [0002] The drying cylinder for printing and dyeing is a drying equipment for printing and dyeing. In the patent application "anti-adhesion, corrosion resistance, energy-saving drying cylinder for printing and dyeing" published by Chinese Patent Application Publication No. 104358055A, it includes the left shaft head, cylinder body, left head, The right head, the right shaft head, and the cylinder body are fixedly connected between the left head and the right head. Attached to the surface of the cylinder, the middle is high and the two sides are low, so that the fabric will naturally slide to the two sides, which increases the flatness of the fabric surface. But the main defect of this drying cylinder for printing and dyeing is: the structural strength and rigidity of the cylinder are poor, and it is eas...
