Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of yarn impregnation and tensioning devices, and particularly relates to a yarn impregnation and tensioning device for a vertically arranged multi-winding mold. Background Technology
[0002] In the field of small-scale fiberglass winding product manufacturing, to improve production efficiency, multiple winding dies are generally arranged vertically, while only one yarn impregnation and tensioning device is used for conveying the yarn. Currently used yarn impregnation and tensioning devices include a frame, on which an impregnation mechanism and a corresponding tensioning mechanism are mounted. The impregnation mechanism includes a glue storage tank, an impregnation roller above the tank, a scraper roller diagonally above the roller, and a rear support frame behind the roller. The tensioning mechanism is located in front of the roller and includes a tensioning lever whose upper end is movably connected to the frame, with a tension spring between the lower end of the lever and the frame. Because winding requires a large number of yarns, three or more impregnation rollers are generally arranged horizontally. The aforementioned yarn impregnation and tensioning device has the following drawbacks: First, during yarn conveying, the yarn is prone to breakage under tension. After breakage, the yarn will wrap around the impregnation roller, requiring the roller to be stopped and the yarn removed. Since all impregnation rollers are located on the same shaft, if a broken yarn is wrapped on one roller, all rollers must be stopped, resulting in low production efficiency. Removing broken yarn is even more difficult when it is wrapped on a roller located in the middle. Second, due to the short lateral distance between the impregnation rollers, it is not possible to use a servo motor to control each roller. Third, because the winding dies are arranged vertically and the yarn drawn from the tensioning mechanism is on the same horizontal plane, the angle between the yarn on each die and the horizontal plane is different, resulting in different winding yarn tensions on each die. This causes products wound with yarn of high tension to be thinner and have poor compressive strength, while products wound with yarn of low tension are thicker and have high compressive strength. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a yarn impregnation and tensioning device for vertically arranged multi-winding molds that has a simple structure, can stop the rotation of a certain impregnation roller at any time, has high working efficiency, and is easy to repair and maintain.
[0004] To solve the above problems, the technical solution adopted by the yarn impregnation and tensioning device for vertically arranged multi-winding molds of this utility model is as follows: It includes a frame, on which a first impregnation mechanism and a first tensioning mechanism corresponding to the first impregnation mechanism are arranged. The first impregnation mechanism includes a first glue storage tank, a first impregnation roller arranged above the first glue storage tank, a first scraping roller arranged diagonally above the first impregnation roller, and a first rear support frame arranged behind the first impregnation roller.

The second impregnation mechanism includes a second glue storage tank, a second impregnation roller is provided above the second glue storage tank, a second scraping roller is provided diagonally above the second impregnation roller, and a second rear support frame is provided behind the second impregnation roller. The second tensioning mechanism is located in front of the second impregnation roller. The second tensioning mechanism includes a second tensioning lever whose upper end is movably connected to the frame. A second tension spring is provided between the lower end of the second tensioning lever and the frame.
[0005] Its additional technical features are: A third impregnation mechanism and a third tensioning mechanism are provided on the frame above the second impregnation mechanism. The third impregnation mechanism includes a third glue storage tank, a third impregnation roller is provided above the third glue storage tank, a third scraping roller is provided diagonally above the third impregnation roller, and a third rear support frame is provided behind the third impregnation roller. The third tensioning mechanism is located in front of the third impregnation roller. The third tensioning mechanism includes a third tensioning swing rod whose upper end is movably connected to the frame, and a third tension spring is provided between the lower end of the third tensioning swing rod and the frame.

When a yarn breaks on one of the impregnation mechanisms, the operator can easily remove the broken yarn by standing on one side of the impregnation roller. Furthermore, the first impregnation mechanism supplies yarn to the winding mold below, and the second impregnation mechanism supplies yarn to the winding mold above.
