Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, it includes a feeding device, a drafting mechanism, a twisting mechanism and a winding mechanism. The feeding device is formed by connecting a group of guide rollers 1, and the drafting mechanism is formed by connecting a group of rollers. The twisting mechanism includes a flyer 2, a false twister 3, and an upper rib 4, and the winding mechanism includes a bobbin 5, a bobbin gear 6, and a lower rib 7, and the bobbin 5 is connected with the bobbin gear 6, The bobbin gear 6 is installed on the lower dragon rib 7, and at least three tension sensors 8 are also arranged between the drafting mechanism and the twisting mechanism for online detection of the roving tension. The drafting mechanism includes a back roller 9, three Roller 10, second roller 11, front roller 12, the tension sensor 8 is placed between the front roller 12 and the fals...

Abstract

The invention relates to coarse spinners, in particular to a coarse spinner with a yarn tension detection function. The coarse spinner with the yarn tension detection function comprises a feeding device, a drafting mechanism, a twisting mechanism and a winding mechanism. The feeding device is formed by a set of guide bar rollers in a connection mode, the drafting mechanism is formed by a set of rollers in a connection mode, the twisting mechanism comprises a flyer, a false twister and an upper keel, the winding mechanism comprises a bobbin, a bobbin gear and a lower keel, the bobbin is connected to the bobbin gear, and the bobbin gear is mounted on the lower keel. The coarse spinner with the yarn tension detection function is characterized in that at least three tension sensors used for detecting yarn tension on line are further arranged between the drafting mechanism and the twisting mechanism. The coarse spinner with the yarn tension detection function can detect the yarn tension on line, and further controls the speed ratio of a main motor and a variable frequency motor, the purpose of adjusting the tension of coarse yarn is achieved, and the coarse spinner with the yarn tension detection function is simple in structural design and easy to achieve.

Description

technical field [0001] The invention relates to a roving frame, in particular to a roving frame with yarn tension detection. Background technique [0002] The roving frame in the prior art includes forming mechanism, upper and lower cone wheels, belt control and other devices, and the motion matching among feeding device, drafting mechanism, twisting mechanism and winding mechanism is realized through complex mechanical transmission chain. This type of roving frame has a complex structure, and cannot accurately detect the yarn tension, nor can it control the stability of the elongation rate, the failure rate is also high, and the performance is more unstable. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a roving frame with yarn tension detection, which can detect the roving tension online, and then control the speed ratio of the main motor and the frequency conversion motor to achieve ...
