Problems solved by technology

In this way, when the licker-in roller hits and combs, the cotton bundles in poor grip will enter the cylinder carding area in different degrees of bundles due to the lack of good grip control, and this discrete bundle feeding will cause separation. Bad combing and variation of carding effect, finally lead to variation of yarn quality
If the number of segments is greatly increased in order to improve the pressure grip of the cotton layer and improve the thickness detection accuracy, the complexity of the mechanical structure and electrical components will increase accordingly, which will increase the cost, complicate the control, and make maintenance difficult

Embodiment Construction

[0018] In conjunction with the accompanying drawings, the 50-section feeding layer holding and thickness detection mechanism for the feeding roller of the carding machine with a transverse width of 1000 mm is described as follows:

[0019] There are 50 segments within a transverse width of 1000 mm, and the width of each segment is 20 mm. Compared with the 10-segment sampling detection and pressurization holding mechanism in the prior art, the width subdivision degree is improved by 5 times.

[0020] In Fig. 1 and Fig. 2, a pressurized grip chamber 2 is arranged parallel to the cotton feed roller 1 above the cotton roller 1, and the pressurized grip chamber 2 is a firm cavity with an opening downward, and the cross-sectional dimension in the chamber is It is 20 millimeters high and 20 millimeters wide, and a soft capsule 3 made of elastic material of a corresponding size is placed in the cavity. Press block 10, press block 10 can have the stroke of 15 millimeters to move up an...

Abstract

A method and mechanism for holding the feed layer of carding machine and measuring its thickness is disclosed. A fluid pressurizing principle is used for segmentally pressure holding of feed layer in transverse width, resulting in uniform pressure to each segment. The volume of liquid transferring and pressurizing cavity is used to reflect the position information of pressurizing block, so only one sensor can measure the information about transverse average thickness of said feed layer. Its advantages are high pressure uniformity and measuring precision, simple structure, and easy regulation.

Description

1. Technical field [0001] The present invention relates to a method for pressurizing and gripping the feeding layer and detecting the thickness of the autolevelling on a carding machine for spinning (cotton spinning carding machine, wool spinning carding machine, hemp spinning carding machine) and mechanism. 2. Background technology [0002] On the new high-quality carding machine (the carding machine is taken as an example in the following full text), there is an autoleveling system. In the prior art, gravity and / or spring force are used to pressurize the cotton layer to hold the cotton layer relative to the cotton roller and the cotton plate (cotton layer holding surface). For the detection of the transverse average thickness of the cotton layer, the most accurate is the ten-section multi-sensor detection on the DK903 carding machine developed and produced by Trutzschler in Germany. The relative position of the cotton feeding plate and the cotton feeding roller is amplif...
