Description

High-speed and high-precision single fiber impregnation machine

The invention relates to a single-fiber impregnation structure, in particular to a high-speed and high-precision single-fiber impregnation machine for impregnation and sizing with a rated amount of glue.

Press, a conventional fabric dipping device, such as "a new type of arranging machine dipping device" approved by the Chinese mainland on November 16, 2018, Announcement No. 208104754, which mainly includes a yarn inlet roller and a yarn outlet The roller, the dipping roller and the glue tank also include an adjustable squeegee roller and a rubber pressure roller. The dipping roller is arranged at the upper end of the glue tank, and the dipping roller is connected with an external power device so that the dipping roller can rotate around the central axis. The yarn feed roller, the adjustable rubber squeegee roller and the rubber roller are arranged on one side of the dipping roller, and the distance between the adjustable rubber squeegee roller and the rubber roller and the edge of the dipping roller is smaller than that between the yarn feed roller and the rubber dipping roller. The distance between the edges, wherein the pressure rubber roller is arranged at the upper end of the adjustable rubber doctor roller, and the yarn delivery roller is arranged on the other side of the rubber dipping roller. Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: the temperature difference between the arrangement and the glue is too large, which will cause the glue temperature to drop rapidly when they contact each other, which will affect the flow of the glue. The adhesiveness and adhesion result in the shortcomings of insufficient dipping amount and the inability to increase the gluing speed. On the other hand, although the adjustable squeegee roller can squeegee the dipping roller, it is actually used as the glue because of its high viscosity. When the yarn speed or the speed of the dipping roller is close to 30m/min, the glue will form a huge resistance to the adjustable squeegee roller, so it will form a wavy overflow of glue (adjustable squeegee roller bounce), resulting in uneven glue amount and The technical problem that the processing speed cannot be increased. Moreover, the temperature of the glue is immediately cooled when it touches the arrangement and when it leaves the dipping roller, so that the glue only penetrates the arrangement surface, and there is no dipping inside the arrangement, thereby reducing its dipping quality.

In view of this, the inventor of the present invention has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, the present invention is truly practical.

A soaking heating box 40 is arranged at one end of the rear guide wheel 14, and a plurality of turning rollers 41 are installed in parallel and different planes in the soaking heating box 40. At least one heater is fixed in the box 40 42, and the soaking heating box 40 constitutes the soaking space when the heater 42 is heated, a fiber heating box 50 is arranged at one end of the front guide wheel 13, and the fiber heating box 50 is installed in parallel and different planes There are a plurality of turning rollers 51, and at least one temperature riser 52 is fixed in the fiber warming box 50, and the fiber warming box 50 constitutes the soaking space when the temperature riser 52 is heated, and a fiber reel group 60 has a plurality of heating devices. The yarn reel 61 and a plurality of yarn take-up reels 62, the yarn release reel 61 and the yarn take-up reel 62 are individually wound with a single bundle of fibers 63, and the single bundle of fibers 63 are wound in the order The yarn release reel 61, the steering roller 51, the front guide wheel 13, the yarn guide groove 111, the rear guide wheel 14, the turning roller 41 and the yarn take-up reel 62, and the single fiber 63 is The fiber winding wheel group 60 is controlled by the front guide wheel 13 to wind in the direction of the rear guide wheel 14.

The actual use situation, please first observe from the figures 1, 2 and 3, the fiber reel group 60 uses the yarn release reel 61 and the yarn take-up reel 62 to form a release of the two ends of the single fiber 63 One retracted, so that the single fiber 63 can be wound on the yarn release reel 61, the turning roller 51, the front guide wheel 13, the yarn guide groove 111, the rear guide wheel 14, and the turning roller in sequence 41 and the take-up reel 62, thereby forming the high-speed yarn unwinding and winding of the single fiber 63, the speed of which is 30m/min to 50m/min, the single fiber 63 enters the fiber heating box 50 before being dipped in glue The single fiber 63 stays in the fiber warming box 50 for an increase of time by winding in a turning shape through the turning roller 51, and uniformly heating through the warming device 52, thereby the single fiber The fiber bundle 63 is preheated. After preheating, the temperature difference between the single fiber 63 and the resin liquid can be reduced, so that when the single fiber 63 contacts the resin liquid, the fluidity and adhesion of the resin liquid will not be reduced. The impregnation wheel set 10 adheres to the resin liquid in the resin tank 12 by the rotation of the impregnation roller 11, so that the single fiber 63 that is driven by the front guide wheel 13 and the rear guide wheel 14 to slide through the yarn guide groove 111 It can be impregnated with resin liquid, wherein the impregnating roller 11 and the single fiber 63 rotate and move in the same direction, and the single fiber 63 After being dipped, it enters the soaking and heating box 40, and is wound in a turning shape through the turning roller 41, so that the single fiber 63 stays in the soaking and heating box 40 for a longer time and passes through the heater 42 Heating at a uniform temperature can maintain the fluidity and permeability of the resin liquid, thereby prolonging the soaking time of the resin liquid to the single fiber 63, so that the glue content inside and outside the single fiber 63 can be uniform, so as to improve its impregnation. For the yield and quality of the glue, please refer to Figure 4 again. The above-mentioned turning roller 41 is installed on a height adjuster 43. Through the height adjuster 43, the up and down displacement of the turning roller 41 can be formed to change the single bundle. The fiber 63 stays in the soaking and heating box 40 for the time, so it achieves the practical function of adjusting the soaking time without affecting the winding and unwinding speed. It is also worth noting that the resin liquid temperature of the resin tank 12 is higher than that of the fiber The temperature in the heating box 50 is increased, and the temperature in the soaking heating box 40 is higher than the resin liquid temperature of the resin tank 12, thereby reducing energy consumption and improving the efficiency of dipping. Finally, the yarn reel 62 is wound and cooled. The single fiber 63 can complete the impregnation and gluing operation of the single fiber 63.

To further explain the use effect of the impregnated wheel set 10, please observe from Figures 1, 2, and 3. When the single fiber 63 enters the impregnated wheel set 10, the front guide wheel 13 and the rear guide wheel 13 are used. The guide wheel 14 presses down the single fiber 63 above the impregnated roller 11, so that the single fiber 63 slips over the yarn guide groove 111 where the impregnated roller 11 is located above. In addition, the resin tank 12 is heated by hot oil The resin is in a liquid state, and the lower part of the impregnated roller 11 is immersed in the resin tank 12. The rotation of the impregnated roller 11 brings the resin liquid to the upper end of the impregnated roller 11, which can achieve the effect of impregnation and the first scraper 20 Set between the impregnated roller 11 and the front guide wheel 13, and scrape a large amount of resin liquid on the surface of the impregnated roller 11 with the blade plane 21 of the first scraper 20, thereby effectively reducing the amount of resin adhesion, and The second scraper 30 is arranged above the first scraper 20, and the convex portion 32 of the second scraper 30 penetrates the yarn guide groove 111, and the second scraper 30 is used By scraping the resin liquid part in the yarn guide groove 111, the amount of glue in the yarn guide groove 111 can be controlled with high precision, so that the winding and unwinding speed of the single fiber 63 and the impregnating roller 11 can rotate at a high speed.
