A rove elongation test counting device

Abstract

The invention provides a rove elongation test counting device and relates to the field of spinning tests. A connector of a rear roller is connected with a port of a counter; the center of the connector and the center of the port are on the same straight line; the counter comprises a dial plate, a pointer, a first gear, a second gear, a third gear and a fourth gear; the first gear installed at one end of the port and the second gear form meshing transmission; the second gear and the third gear are installed at the two ends of a concentric shaft; the third gear and the fourth gear form meshing transmission; the fourth gear and the pointer are installed at the two ends of a circular shaft; the pointer rotates around the dial plate with the circular shaft as the center; the gear moduli of the first gear, the second gear, the third gear and the fourth gear are identical; the numbers of teeth of the first gear, the second gear, the third gear and the fourth gear are 10, 50, 10, 100 respectively; the first gear, the second gear, the third gear and the fourth gear are made of nylon wear-resistant materials. The rove elongation test counting device can accurately count the rotation circles of a rear roller of a roving frame, prevent calculation error caused by manual counting error, and effectively improve the accuracy of rove tension calculation and enables rove tension to be better controlled.

Description

Technical field [0001] The invention relates to the technical field of textile production testing, in particular to a roving elongation test and counting device. Background technique [0002] In the production process of the textile field, the cooked sliver produced by the drawing process is fed to the roving frame and wound into a roving by the drafting mechanism and the twisting mechanism. In the roving winding process, in order to ensure the normal winding of the roving, the winding speed of the roving bobbin must be greater than the output speed of the front roller, so that the roving always maintains a certain degree of tension during the winding process. This tension is called Is the roving tension. The test and adjustment of roving tension are useful for reducing accidental drafting of roving, ensuring roving evenness, controlling weight unevenness, maintaining good shape, and improving the inherent quality of roving during different spinning stages of large, middle, and ...
