Abstract
Description
Technical Field
[0001] The utility model relates to the field of loom material frames, in particular to a warp yarn constant tension adjustment frame. Background Art
[0002] Common loom material racks are fed through warp bobbins. As the warp yarns decrease during the feeding process, the radius of the warp bobbin decreases. This leads to a gradual decrease in warp tension during the delivery process. Insufficient warp tension can reduce product yield. The traditional method of applying constant tension is to add weights to the yarn delivery end of the warp bobbin, and then change the weights to different weights as the warp yarns decrease. Utility Model Content

[0005] In some embodiments, adjacent adjustment rollers are staggered, with the adjustment roller at the front being higher than the adjustment roller at the rear.
[0006] In some embodiments, an import roller is provided on the front side of the constant tension adjustment device, and a third driver is provided on one side of the main frame. The third driver drives the import roller to rotate, and grooves for accommodating the import counterweight roller are provided on both sides above the import roller. The import counterweight roller is in contact with the import roller.
[0007] In some embodiments, the constant tension adjustment device includes four sets of adjustment rollers.
[0008] Compared with the prior art, the beneficial effects of this application are:
[0009] This application uses a stranded product containing a twisted wire and multiple warp yarns for feeding. During the feeding process, the twisted wire is recovered by a stranded wire take-up device. The first drive drives the main roller and the secondary roller to rotate in conjunction with the counterweight roller so that the warp yarn always fits the adjustment roller. The constant tension is adjusted by the torque of the motor, and there is no need to repeatedly replace the weights, saving manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0013] refer to Figs. 1-2 , the present application provides a warp constant tension adjustment frame for separating the warp yarn and twisted wire in the strand-like product, comprising: a main frame 1, a constant tension adjustment device 2 is provided in the middle of the main frame 1, and a stranded wire take-up device is provided on the top of the main frame 1, the constant tension adjustment device 2 comprises at least two groups of adjustment rollers, the adjustment rollers comprise a first drive 3, a main roller 4, a secondary roller 5 and a counterweight roller 6, the main roller 4 and the secondary roller 5 are arranged parallel to each other, the first drive 3 drives the main roller 4 and the secondary roller 5 to rotate in the same direction respectively, and the counterweight roller 6 is mounted between the main roller 4 and the secondary roller 5; the stranded wire take-up device comprises a second drive and a strand drum 7, the second drive drives the strand drum 7 to rotate, and after the strand-like product passes through the constant tension adjustment device 2, the stranded wire therein is rotated and drawn out by the strand drum 7, and the remaining warp yarn enters the next process.
[0014] In some embodiments, the adjacent adjustment rollers are staggered, the adjustment roller at the front is higher than the adjustment roller at the back, and staggered yarn movement from high to low can prevent the warp yarn from being entangled and knotted with the twisted yarn.
[0015] In some embodiments, an import roller 8 is provided on the front side of the constant tension adjustment device 2, and a third driver 9 is provided on one side of the main frame 1. The third driver 9 drives the import roller 8 to rotate. Grooves for accommodating an import counterweight roller 10 are provided on both sides above the import roller 8. The import counterweight roller 10 is in contact with the import roller 8. The addition of the import roller 8 can enhance the stability of the strand-like product during introduction.
[0016] In some embodiments, the constant tension adjustment device 2 includes four sets of adjustment rollers.
[0017] The first driver 3 , the second driver and the third driver 9 in the present application are all motors.
[0018] The wiring process of the present application is specifically as follows: the stranded product is led out from the storage barrel (the stranded product does not need to be wound on the warp yarn tube), the import counterweight roller 10 is manually lifted, so that the import counterweight roller 10 presses the stranded product against the import roller 8, and then the stranded product passes through multiple groups of adjustment rollers from high to low in sequence. After passing through the adjustment rollers, the stranded wires in the stranded product are collected by the stranding and winding device above, and the remaining warp yarns are introduced into the next process; the specific constant tension is adjusted by the torque meter of the first driver 3.
[0019] This application uses a stranded product containing a twisted wire and multiple warp yarns for feeding. During the feeding process, the twisted wire is recovered by a stranded wire take-up device. The main roller 4 and the secondary roller 5 are driven by the first driver 3 to rotate and cooperate with the counterweight roller 6 so that the warp yarn always fits the adjustment roller. The constant tension is adjusted by the torque of the motor, and there is no need to repeatedly replace the weights, saving manpower and material resources.
[0020] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
