Rigid fixed-distance raw silk size detector and manufacturing method thereof

Abstract

The invention provides a rigid fixed-distance raw silk size detector for improving the overall accuracy and realizing mass production conveniently, which comprises a first glass sheet and a second glass sheet, wherein the first glass sheet and the second glass sheet are in the same symmetry and are symmetrically arranged; and one side of the first glass sheet facing the second glass sheet and oneside of the second glass sheet facing the first glass sheet comprise a working surface, a contact surface and an isolating groove. The rigid fixed-distance raw silk size detector provided by the invention does not adopt a film, adopts the contact surface and the working surface which are formed directly by the glass surfaces, improves the overall accuracy, is convenient for realizing interchangeability of mass production, improves the production efficiency, basically solves the error of detection gaps caused by assembling parts of the raw silk size detector, and plays a key role in reducing the deviation between ends for silk reeling enterprises.

Description

technical field [0001] The invention relates to a device for controlling the fineness of raw silk of an automatic silk reeling machine and a manufacturing method thereof, belonging to the fields of silk-making machinery and silk-making technology. Background technique [0002] In the past, sensors used to detect and control the fineness of raw silk in automatic reeling machines, such as the Chinese utility model patents with patent numbers 93221598.X and 200620107628.2, are composed of two processed symmetrical glass sheets and a measured film. On the opposite surfaces of the two symmetrical glass sheets, a gap is formed in the middle of the two glass sheets for the passage of raw silk strands after the mandrel, gasket, and nut are connected and assembled. When the raw silk passes through this gap, it rubs against the glass sheet to generate friction. The "gap" is the "gap for detection", and the fineness detection and control in the raw silk production process can be realiz...

AI Technical Summary

Problems solved by technology

[0005] 1. The film is an elastic body, the size cannot be guaranteed to be consistent, and the accuracy cannot meet the requirements of the raw silk detection for the gap, so as to determine the non-uniformity of the gap for raw silk fineness detection, which affects the size of the raw silk fineness detection gap;

[0006] 2. The film is a thermoplastic material. Because it is stretched and stretched, the precision of the film thickness and unevenness is poor, and there is a large inspection workload; the film thickness values ​​​​measured by different measuring compression forces will also be different. The same detection pressing force cannot be guaranteed;

[0007] 3. The specifications of the film cannot meet the detection needs of any raw silk specifications; the combination method not only requires a lot of work but also may not be fully realized;

[0008] 4. The film has elastic deformation. Even with the same film thickness, the gap formed by different tightening forces will be different. There are human factors that affect the gap accuracy of raw silk fineness detection;

[0009] 5. Due to the uneven thickness of the film, it is difficult to ensure the parallelism between the two glass sheets after assembly, resulting in uneven spacing between the raw silk fineness detection gaps
