Problems solved by technology

[0003] Since the development of the washing machine, the rolls have been continuously updated. The currently widely used washing rolls are steel pipes with glue coating, which still has many shortcomings: 1. The steel rolls are heavy, which leads to high energy consumption and high transportation costs.
When it is necessary to further increase the width of the washing machine, it is necessary to continuously increase the wall thickness of the steel roll to meet the higher rigidity requirements. Therefore, the self-weight of the equipment is further increased, and the energy loss is more serious; 2. The fatigue resistance of the steel roll is not good. Well, due to the poor ductility of the metal, as the width of the washing machine increases, the steel rolls will gradually accumulate deformation until they are completely deformed and cannot be used, resulting in high frequency of roll replacement and greatly increased costs
3. The weight of the wide roll is very heavy. For example, the roll shell with a length of 4300m has an original weight of about 1350 kg. It is very difficult for workers to install and disassemble. It must be moved by driving or many people, which increases the labor of workers. Intensity, but also increased energy consumption, increased costs

Embodiment 1

[0026] Embodiment 1, a kind of preparation method of steel-lined washing roll, its steps are as follows:

[0027] (1) Preparation of steel inner liner roll: choose hot-rolled seamless pipe, and cut it according to the size to form the inner liner shell; then choose 45# steel, and cut it according to the design size to form the left and right shaft head blanks, bulkhead blanks and plugs For the blank, the left and right axle head blanks, bulkhead blanks and plug blanks are respectively rough-turned by a lathe, leaving a 2-3 mm margin for finish turning, and then the turned left and right axle heads are subjected to quenching and tempering treatment and anti-rust treatment, so that The hardness reaches HB235; then the shaft head, plug, and bulkhead are welded into the shaft head assembly; after the inner roller shell is heated at 300-350°C, the shaft head assembly and the inner roller shell are combined and hot-packed in place , after it cools down slowly, the shaft head assembl...

Embodiment 2

[0036] Example 2, in the preparation method of the steel-lined washing roll described in Example 1, when two layers are cross-wound according to ±20°, the tension is 4 N, and when two layers are wound according to 90° hoop, the tension is 8 N. When two layers are cross-wound according to ±32°, the tension is 4 N, when two layers are cross-wound according to ±45°, the tension is 5 N, when two layers are wound according to 90° hoop, the tension is 8 N.

Embodiment 3

[0037] Example 3, in the preparation method of the steel-lined washing roll described in Examples 1 and 2, the rubber roll is vulcanized, and the step of the vulcanization process is to wrap and wrap several layers of cotton cloth or nylon cloth on the outer surface of the rubber roll, and then Fix it with steel wire or fiber rope; then put the rubber roller into a steam vulcanization tank for vulcanization treatment, the vulcanization temperature is 120-150°C, and the vulcanization time is 2-4 hours; Open cotton or nylon cloth and steel wire or fiber rope.

Abstract

The invention provides a method for preparing steel lining washing rollers, which includes the following steps: firstly preparing a steel lining roller; then winding the steel lining roller with a carbon fiber layer, wherein during the winding process, frictioning is performed manually while winding to increase the content of carbon fiber; placing the steel lining roller wound with the carbon fiber layer in a curing box for heating and curing; performing the skim coating on the roller surface subjected to curing; finally preparing the finished steel lining composite carbon fiber washing roller. The finished steel lining composite carbon fiber washing roller prepared through adopting the method provided by the invention has the advantages of light weight, antifatigue, excellent rigidity, corrosion resistance and long service life.

Description

technical field [0001] The invention relates to a component of a wide-width washing machine, in particular to a method for preparing a steel-lined composite carbon fiber washing roll. Background technique [0002] In the process of textile printing and dyeing, washing is a key process, especially for wide-width velvet printed fabrics. Only when the fabric is fully washed, the velvet surface will not be scalded during the finishing and ironing process can achieve the desired effect. The plush effect that people expect, so as to obtain a warm and comfortable textile fabric, this kind of fabric is the first choice for thermal underwear, outdoor clothing, and sports clothing. Therefore, the weight and life of the washing machine, especially the wide-width washing machine, are constantly put forward higher requirements, and the washing roll, which is a key component of the washing machine, is constantly improving at the same time. [0003] Since the development of the washing ma...
