Description

Intelligent shearing machine and shearing process for easy-to-crimp cloth

Technical Field

The invention relates to the technical field of textile machinery, in particular to an intelligent shearing machine and shearing process for easily curled cloth.

Background

The shearing machine is a textile finishing device, is one of the main devices for finishing plush products, and the surface plush fibers of the plush fabrics after weaving, untwisting or fuzzing are different in length, so that the plush fabrics are sometimes required to be sheared and leveled, or the surface terry is required to be sheared and leveled by the terry knitting, thus the aim of the shearing machine is achieved.

The shearing machine is widely applied to textile industry, mainly in order to trim and trim fibers on the surface of cloth, because the shearing machine is in a long-time running state, in order to ensure uninterrupted supply of the cloth, when the shearing treatment is carried out on the same batch of cloth, the end parts of the cloth are connected through sewing, the thickness of the end parts of the single cloth is thickened, joints are formed, the joint positions cannot be effectively judged when the shearing machine shears the cloth, manual observation and cutter lifting are needed in the working process, the cutter collision is easily caused due to errors, the cutter setting position is influenced, the cloth is damaged, when the cutter is lifted, the machine is controlled to move upwards to achieve the aim of passing cloth heads, and because the weight of the circular cutter is large, equipment is required to provide large lifting force for lifting the circular cutter, equipment vibration is easily caused when the circular cutter is lifted and falls, the cutter resetting position accuracy is influenced, and therefore the shearing effect is greatly influenced.

On the other hand, in the production process of part of specific cloth, as the length of the surface fluff is longer, and the fluff is easily attached to the cloth base layer due to static electricity or other reasons, the fluff cannot be effectively erected, and the shearing machine cannot trim the tidy surface, so that the shearing machine is required to have the functions of beating and carding, the existing shearing machine cannot meet the shearing requirement of the specific cloth, and the surface pretreatment capability of the cloth is not provided.
