Description

Technical Field

[0001] This utility model relates to the field of yarn conveying technology, specifically a double roller tension stabilizing device. Background Technology

[0002] In the yarn conveying process in the textile industry, as the yarn unwinds from the package, the constantly changing package diameter causes a change in the wrap angle between the yarn and the guide rollers, resulting in fluctuations in yarn tension. This instability in tension can severely affect the quality and efficiency of subsequent processing steps.

[0003] Currently common tension control devices have complex structures or limited adjustment accuracy, making it difficult to achieve constant tension conveying throughout the entire process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dual-roller tension stabilizing device, which solves the problem of unstable tension in yarn during conveying. By moving the tension roller, the yarn can maintain the same stable wrap angle when it is conveyed to the guide roller, thereby improving the stability of the conveying tension.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double roller tension stabilizing device, comprising a conveyor body, a conveying roller rotatably disposed on the inner side of one end of the conveyor body, a support plate disposed on the other end, a steering roller rotatably disposed on the inner side of the upper end of the support plate, a tension roller disposed on the inner side of the lower end of the support plate, and a moving mechanism disposed on the outer side of the support plate, which drives the tension roller to move up and down to maintain the stability of the yarn output tension.

[0006] Furthermore: the moving mechanism includes a drive motor fixed to the outside of the support plate, a rotating rod fixedly connected to the output end of the motor, a gear fixed on the rotating rod, a support member fixed to the back side of the support plate, and the rotating rod and the support member being rotatably connected.

[0007] Furthermore: a fixed plate is fixed to the outer side of the conveyor body, a limiting slide is fixed to the inner side of the fixed plate, a rack is fixed to the inner side of the fixed plate, a slide groove is opened on the outer side of the rack, a limiting slide is fixed to the inner end of the fixed plate and slides in cooperation with the slide groove, and the gear is meshed with the rack.

[0008] Furthermore: the tension roller is fixed with adapter rods at both ends, the adapter rods are fixedly connected to the rack, and the support plate is provided with vertical strip-shaped through holes for the adapter rods to move.

[0009] Furthermore: the support members are symmetrically fixed on the outer side of the support plate.

[0010] Furthermore, a stabilizing rod is fixedly connected between the two racks.

[0011] This invention provides a dual-roller tension stabilizing device. Compared with the prior art, it has the following advantages: This dual-roller tension stabilizing device uses a motor-driven gear and rack mechanism to precisely control the vertical displacement of the tension rollers, automatically compensating for tension fluctuations caused by changes in yarn roll diameter, and keeping the angle between the yarn and the guide roller constant. This achieves tension stability throughout the entire process from full roll to empty roll. The device has a simple and compact structure, precise control, and effectively improves the quality of subsequent processed products. Attached Figure Description
