Embodiment 1

[0014] Such as figure 1 As shown, the single-sided twill doffer clothing involved in this embodiment includes a base 1 and needle teeth 2 evenly distributed on the base 1. At least two raised or recessed twill patterns 3 are provided on the bevel of the needle teeth 2 3 The angle θ between the bottom surface of the base and the base is 45-55°

[0015] Further, the thickness of the twill weave in this embodiment is D=0.02mm-0.08mm, the height of the twill is H=0.02mm-0.06mm, the distance between two adjacent twills is L=0.02mm-0.06mm, the highest point of the twill The distance from the top surface of the needle tooth is M=0.03mm-0.05mm.

[0016] Preferably, the thickness of the twill weave in this embodiment is D=0.05mm, the height of the twill is H=0.04mm, the distance between two adjacent twills is L=0.04mm, and the distance between the highest point of the twill and the top surface of the pin tooth is M= 0.04mm, the number of twill lines is 2-3.

[0017] Further, the needle tip ...

Abstract

The invention discloses a single-sided twill doffer card clothing. The clothing comprises a base and pin gears evenly distributed on the base, at least two raised or concave twill is arranged on the inclined surfaces of the pin gears, the angles between the twill and the bottom of the base are theta=45-55 degrees, the thickness of the twill is D=0.02mm-0.08mm, the height of the twill is H=0.02mm-0.06mm, the distance between two adjacent twill is L=0.02mm-0.06mm, and the distances between the highest point of the twill and the top surfaces of the pin gears are M=0.03mm-0.05mm. Compared with horizontal stripes, the position of the twill on the pin gears is adjusted upwards to ensure the grasping force of fibers; as doffer rotates, the angles of the twill are consistent with process requirements, when it is necessary to grasp the fibers, the fibers are grasped tightly, when it is necessary to transfer the fibers, the fibers are transferred, it is beneficial to fiber grabbing, carding andtimely transferring, the transfer rate is improved, the fiber transfer rate is improved, the smoothness of the stripping of a stripping roller is improved, and the quality of cotton webs and final index of resultant yarns are improved.

Description

Technical field [0001] The present invention relates to the technical field of textile machinery, in particular to a doffer card clothing used on a carding machine. By arranging twill on one side of the needle teeth, when the doffer rotates, the angle of the twill meets the requirements of the technological process to achieve good carding The effect of fiber. Background technique [0002] The carding machine is used to process cotton fibers and chemical fibers. The cotton (fiber) rolls sent from the previous process or the cotton (chemical fiber) layers supplied by the cotton box are opened, carded and impurity removed, so that all are crimped blocks The cotton mass becomes a basically straight single fiber. The doffer is an important part of the carding process, and the doffer card clothing is the core carding element of the doffer working area. The fiber will be transferred to the surface of the doffer card after the main carding of the cylinder-flat plate is combed, and then ...
