[0003] The Chinese patent with the application number 200520071691.0 discloses the structure of the combing machine wall panels. The wall panels stand parallel to each other. There are connecting struts, the connecting base adopts a box-type structure, and the positioning surfaces of the base at both ends of the connecting base and the positioning surface of the wall panel at the bottom of the wall panel are mutually fitted and positioned, but this wall panel structure does not solve the problem of stress concentration, which seriously The stress concentration mainly occurs at the positions of the two square holes

Embodiment
[0015] A novel structure of the comber support wall panel, the structure of which is as follows figure 1 As shown, it can be used in the CM500 type comber, with a size of 1050mm in height, 970mm in width and 35mm in thickness. located in the upper right corner and the lower left corner respectively.
[0016] The side-length ratio of the square hole is 0.9-1.1, that is, the length and width of the hole are basically equal. In this embodiment, the side-length ratio of the square hole is 1, which can reduce dynamic stress on the one hand, and facilitate observation and The pipeline runs through. . The corner radius of the square hole is 0.2-0.5 of the side length of the hole, which is 0.2 in this embodiment, which has achieved the purpose of minimizing the dynamic stress. The vertical distance between the two square holes is 0.37-0.4 of the distance between the left and right ribs of the two square holes, and the horizontal distance between the two square holes is 0.13-0.15 of...

The invention relates to a combing machine supporting wallboard with a novel structure. The combing machine supporting wallboard is applied to a CM500 combing machine and is of a rib plate type structure. Reinforcing ribs are distributed on the combing machine supporting wallboard, holes are formed in the combing machine supporting wallboard, and two square holes are further formed in the supporting wallboard and are respectively positioned at the right upper corner and the left lower corner of the supporting wallboard. Compared with the prior art, the combing machine supporting wallboard has the advantages that the two square holes are obliquely opposite to each other, the first square hole is positioned at the right upper corner of the supporting wallboard, the second square hole is positioned at the left lower corner of the supporting wallboard, and accordingly the maximum dynamic stress of the combing machine supporting wallboard can be reduced by 2 / 3.
Description
technical field [0001] The invention relates to a combing machine accessory, in particular to a novel-structured combing machine supporting wall plate. Background technique [0002] In cotton spinning engineering, combing is the key process to improve the yarn quality. With the continuous improvement of yarn quality requirements in domestic and foreign markets, the status of the combing process is more important than in the past, and the study of high-efficiency combers has become an important topic for cotton textile machinery. There are a number of similar components in combers, such as high-speed reciprocating nipper assemblies, which generate large shocks, vibrations and noise. Therefore, their support, the comber wallboard, must have sufficient strength. The comber has complex movements, and the wall panels are subjected to the vibration forces and vibration moments from these complex movements. With the continuous increase of the speed of the main shaft of the combe...
