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 winding molds. 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 for winding dies include a frame, an impregnation mechanism, and a tensioning mechanism. The impregnation mechanism includes an impregnation tank, an impregnation roller above the tank, a scraping roller diagonally above the roller, and a rear support frame behind the roller. The tensioning mechanism is located in front of the impregnation roller and includes a tensioning shaft connected to the frame, multiple tensioning rods movably connected to the shaft, and a tension spring connecting the tensioning rods and the frame. The rear end of the tension spring is connected to the same position on the frame. After the yarn on the yarn frame is impregnated by the yarn impregnation and tensioning device, it reaches the winding die via the yarn loop on the tensioning rod. Because the molds are arranged vertically, the angle at which the yarn tilts after it extends from the yarn loop is different, the angle at which the tensioning rod swings is different, and the deformation of the tension spring corresponding to the tensioning rod is different. Therefore, the tension generated by the tensioning rod is different, and the tension of the yarn wound on each mold is different, resulting in different product thickness and 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 a winding mold that is simple in structure, easy to adjust, has uniform tension, produces products with uniform thickness and consistent compressive strength.
[0004] To solve the above problems, the technical solution adopted by the yarn impregnation and tensioning device for winding mold of this utility model is as follows: it includes a frame, an impregnation mechanism, and a tensioning mechanism. The impregnation mechanism includes an impregnation tank, an impregnation roller is arranged above the impregnation tank, a scraping roller is arranged diagonally above the impregnation roller, and a rear support frame is arranged behind the impregnation roller. The tensioning mechanism is located in front of the impregnation roller. The tensioning mechanism includes a tensioning shaft connected to the frame, multiple tensioning rods movably connected to the tensioning shaft, and a tension spring connecting the tensioning rods and the frame. A yarn ring is arranged below the tensioning rods. A tension adjusting seat is arranged on the frame below the impregnation tank. A tension adjusting mechanism corresponding to the number of tensioning rods is arranged on the tension adjusting seat. The tension spring is connected to the corresponding tension adjusting mechanism.
[0005] Its additional technical features are: The tension adjustment mechanism includes a tension adjustment screw and a tension adjustment nut corresponding to the tension adjustment screw. A nut limiting slide is provided on the side of the tension adjustment nut. The rear end of the tension spring is connected to the tension adjustment nut. An adjustment handwheel is provided at the end of the tension adjustment screw.
[0006] Compared with the prior art, the yarn impregnation and tensioning device for winding molds provided by this utility model has the following advantages: Firstly, it includes a frame, an impregnation mechanism, and a tensioning mechanism. The impregnation mechanism includes an impregnation tank, an impregnation roller above the impregnation tank, a scraping roller diagonally above the impregnation roller, and a rear support frame behind the impregnation roller. The tensioning mechanism is located in front of the impregnation roller. The tensioning mechanism includes a tensioning shaft connected to the frame, multiple tensioning rods movably connected to the tensioning shaft, and a tension spring connecting the tensioning rods and the frame. A yarn loop is provided below the tensioning rod. A tension adjusting seat is provided on the frame below the impregnation tank, and a tension adjusting mechanism corresponding to the number of tensioning rods is provided on the tension adjusting seat. The tension spring is connected to the corresponding tension adjusting mechanism. During winding, the position of the rear end of the tension spring is adjusted according to the tension on each tensioning rod through the tension adjusting mechanism corresponding to each tension spring, so that the tension on each tensioning rod is adjusted. Equal elongation means that during the winding process, the elongation of the tension springs is observed to ensure that the elongation of all tension springs is basically equal. When the elongation of a certain tension spring is large, the rear end of that spring is moved forward appropriately through the tension adjustment mechanism until the elongation of that spring is equal to that of the other tension springs. Conversely, when the elongation of a certain tension spring is small, the rear end of that spring is moved backward appropriately through the tension adjustment mechanism until the elongation of that spring is equal to that of the other tension springs. In this way, the thickness and compressive strength of the products produced by winding on each mold are basically equal, resulting in good product quality. Secondly, since the tension adjustment mechanism includes a tension adjustment screw and a corresponding tension adjustment nut, a nut limiting slide is provided on the side of the tension adjustment nut. The rear end of the tension spring is connected to the tension adjustment nut, and an adjustment handwheel is provided at the end of the tension adjustment screw. By adjusting the handwheel, the tension adjustment screw is rotated, and the tension adjustment nut moves back and forth along the nut limiting slide, making adjustment more convenient.

Detailed Implementation
[0008] The structure and operating principle of the yarn impregnation and tensioning device for winding molds of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0009] like Figure 1 , Figure 2 and Figure 3 The diagram shows the structure of the yarn impregnation and tensioning device for winding molds according to this invention. The device includes a frame 1, an impregnation mechanism 2, and a tensioning mechanism 3. The impregnation mechanism 2 includes an impregnation tank 21, an impregnation roller 22 positioned above the tank, a scraping roller 23 positioned diagonally above the roller, and a rear support frame 4 positioned behind the roller. The tensioning mechanism 3 is located in front of the roller. The tensioning mechanism 3 includes a tensioning shaft 31 connected to the frame 1, multiple tensioning rods 32 movably connected to the shaft, and tension springs 33 connecting the rods 32 and the frame 1. A yarn ring 321 is positioned below the tensioning rods 32. A tension adjusting seat 34 is positioned on the frame 1 below the impregnation tank 21, and tension adjusting mechanisms 5 corresponding to the number of tensioning rods 32 are positioned on the tension adjusting seat 34. The rear end of each tension spring 33 is connected to its corresponding tension adjusting mechanism 5. Of course, tension spring 33 can be made of tendon or as a weight for traction.
[0010] During winding, the yarn 6 passes through the yarn loop 321 of the rear tensioning frame 4, the dipped roller 23, and the tension rod 32, and then reaches the winding die. Based on the tension on each tension rod 32, the position of the rear end of each tension spring 33 is adjusted by the tension adjustment mechanism 5 corresponding to each tension rod, ensuring equal tension on each tension rod. In other words, during winding, the elongation of the tension springs 33 is observed, ensuring that the elongation of all tension springs 33 is substantially equal. When the elongation of a certain tension spring 33 is large, the rear end of that spring is moved forward appropriately by the tension adjustment mechanism 5 until its elongation is equal to that of the other springs. Conversely, when the elongation of a certain tension spring is small, the rear end of that spring is moved backward appropriately by the tension adjustment mechanism 5 until its elongation is equal to that of the other springs. In this way, the thickness and compressive strength of the products wound on each die are substantially equal, resulting in high-quality products.
[0011] The tension adjustment mechanism 5 includes a tension adjustment screw 51 and a tension adjustment nut 52 corresponding to the tension adjustment screw 51. A nut limiting slide 53 is provided on the side of the tension adjustment nut 52. The rear end of the tension spring 33 is connected to the tension adjustment nut 52. A bearing seat 54 is provided on the tension adjustment seat 34 at the front end of the tension adjustment screw 51. The front end of the tension adjustment screw 54 is connected to the bearing seat 54 through the bearing. An adjustment handwheel 55 is provided at the rear end of the tension adjustment screw 51. By adjusting the handwheel 55, the tension adjustment screw is rotated, and the tension adjustment nut moves back and forth along the nut limiting slide, which makes the adjustment more convenient.
[0012] The scope of protection of the yarn impregnation and tensioning device for winding mold of this utility model is not limited to the above embodiments. As long as the structure is the same as or similar to the structure of the yarn impregnation and tensioning device for winding mold of this utility model, it falls within the scope of protection of this utility model.
