Tension-free cloth inspecting machine for open-width knitted fabric

Abstract

The invention discloses a tension-free cloth inspecting machine for open-width knitted fabric, and relates to the technical field of textile equipment, the tension-free cloth inspecting machine comprises a mounting plate, a negative pressure guide assembly, a cleaning assembly, a deviation rectifying assembly, a sensing assembly and a cloth inspecting assembly are mounted on the mounting plate, and the negative pressure guide assembly and the cleaning assembly are connected with a negative pressure driving assembly; the negative-pressure guide assembly comprises a first negative-pressure guide roller, a movable negative-pressure roller and a second negative-pressure guide roller which are sequentially arranged above the mounting plate, and the interiors of the first negative-pressure guide roller, the movable negative-pressure roller and the second negative-pressure guide roller are of cavity structures; by means of the arranged negative pressure guide assembly, in the cloth inspecting process, the interiors of the first negative pressure guide roller, the movable negative pressure roller and the second negative pressure guide roller are in a negative pressure state, suction force is generated through negative pressure suction holes, and therefore friction force between the first negative pressure guide roller, the movable negative pressure roller and the second negative pressure guide roller and cloth in the longitudinal direction is effectively increased; and the condition of cloth deviation caused by external force is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a tension-free cloth inspection machine for plain knitted fabrics. Background technique [0002] Plain knitted fabric has the characteristics of soft texture, moisture absorption, breathability, perspiration and warmth retention, and most of them have excellent elasticity and extensibility. During the production process of flat-width knitted fabrics, the surface needs to be inspected to ensure the quality of the fabrics. At this time, a fabric inspection machine is needed. [0003] The retrieved publication number is CN206679955U utility model patent, which discloses a tension-free cloth inspection machine for open-width knitted fabrics, including a frame, a cloth box, a cloth rocker a, a cloth rocker b, a tension shaft, and a guide Shaft a, guide shaft b, lead screw spreading shaft a, roller a, lighting light box, upper light box, roller b, control cabinet, lead screw...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned invention has the following disadvantages: when the above-mentioned patent is used, there is a lack of corresponding cleaning design, and the thread ends and broken threads attached to the surface of the cloth can easily lead to misjudgment by the machine or inspectors, thereby reducing the efficiency of cloth inspection; in addition, the above-mentioned patent And in the prior art, the friction force between the cloth guide part and the cloth in the longitudinal direction is low. In the prior art, the deviation correction method of simple guide roller movement is used. When facing the smooth surface of the cloth, the cloth cannot closely follow the guide roller. , leading to a great reduction in the effect of correcting the deviation of the fabric, and even the failure of deviation correction, so there are limitations
