Top roller gin structure of top roller gin machine
Fabric science and technology are advancing rapidly. The market has higher and higher requirements for fabric quality. Fabric industry equipment is constantly upgrading. Fabrics are progressing from coarse special yarn products to fine special yarn products. Fine velvet cotton can no longer meet the needs of the fabric industry. , due to the increasing market demand for long-staple cotton, the area for planting long-staple cotton continues to expand, and top roller gins adapted to finishing long-staple cotton have been welcomed by the market. The top roller gin machine has also progressed from the past knife-type top roller gin machine to the hob-type top roller gin machine.
1. The structure of the top roller gin machine
The top roller gin machine is divided into two types according to its main working component – the moving knife.
The production efficiency of the punch-knife top roller gin is low, and the lint yield is about 1.3kg/(piece?h). In our country, the punch-knife top roller gin is used for fine cotton finishing in a few villages, and in some areas In addition to being used as a long-staple cotton finishing machine, it is mainly used as an inspection machine for sub-cotton purchasing. National regulations: The classification of sub-cotton clothing shall be based on the test rolling of the knife-type top roller gin.
Our country’s hob-type top roller gin is evolved from the foreign hob-type gin. In the early 1960s, the United States successfully developed a hob-type top roller gin, using a rotating leisure hob instead of a reciprocating leisure punching knife. This new type of top roller gin has greatly improved production efficiency and increased lint yields. It can reach more than 5kg/(piece h). It is an ideal finishing machine for the large-scale production of long-staple cotton and an ideal finishing equipment for medium- and long-staple cotton.
