Description

Technical Field

[0001] This utility model belongs to the technical field of fiber winding production equipment, specifically relating to a fiber winding nozzle device for improving yarn spreading stability. Background Technology

[0002] Fiber winding is one of the main manufacturing processes for resin-based composite materials. It involves impregnating continuous fiber rovings or cloth strips with resin and continuously winding them onto a mandrel or liner corresponding to the internal cavity size of the product under controlled tension and a predetermined shape, and then curing them at room temperature or under heating conditions to produce a product of a certain shape.

[0003] In fiber winding molding processes, existing solutions typically use straight-bar rollers or arc-shaped fixed nozzles to control and maintain the unfolding of the yarn and its winding with the core film. Currently, the winding nozzles used are arc-shaped or straight-bar fixed nozzles. When the fiber winding machine changes angle, the yarn may shift at the nozzle position, resulting in overlapping or forked gaps in the yarn width due to the change in nozzle angle. This leads to unstable yarn width control, and the overlapping or forked yarns are prone to uneven thickness when winding pressure vessels, affecting product quality. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems by providing a fiber winding nozzle device using a circular annular nozzle. This device ensures that the yarn can be fully unwound at any angle by keeping the arc of the annular nozzle constant, and at the same time, the yarn position is stabilized and fixed by the guide comb, so that the yarn maintains the unwound width at any position when the fiber winding machine changes angle, thereby improving product quality.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a fiber winding nozzle device to improve yarn spreading stability is as follows:

[0006] The device includes a gearbox; a fixed disc is rotatably connected to the gearbox, and a yarn nozzle angle rotary motor for driving the fixed disc to rotate is connected to the outside of the gearbox. A support is mounted on the fixed disc; the rear end of the support is connected to the fixed disc, and a yarn nozzle coaxial with the fixed disc is mounted on the front half of the support; the yarn nozzle is annular; and several yarn guides for guiding the yarn are also connected to the rear side of the yarn nozzle on the support.

[0007] The support is a long triangle.

[0008] The support has a circular hole in the middle to reduce its own weight.

[0009] A motor mounting plate is detachably connected to the gearbox; the screw nozzle angle rotary motor is mounted on the motor mounting plate by bolts.

[0010] The motor mounting plate has vertical grooves at each of its four corners; the motor mounting plate is connected to the gearbox by fixing bolts; the bottom end of the fixing bolt passes through the vertical groove and is threaded into the gearbox.

[0011] A gasket is placed between the motor mounting plate and the fixing bolts.

[0012] A fixing plate is also bolted to the gearbox; an anti-loosening bolt is attached to the fixing plate; an adjusting nut is threaded onto the anti-loosening bolt, and the lower end of the anti-loosening bolt vertically passes through the fixing plate and is threaded to the motor mounting plate; the fixing plate is located above the motor mounting plate, and the adjusting nut abuts against the top of the fixing plate.

[0013] The technical effects that this utility model can achieve are:

[0014] 1. The nozzle of this utility model is in the shape of a ring. The ring design ensures that the curvature of the ring remains unchanged at any angle when the nozzle changes in any angle, thereby ensuring that the yarn can be fully unfolded at any angle. The guide comb fixes the position of the yarn and improves the stability of the yarn unfolding width when the yarn is wound around the core film.

[0015] 2. The support of this utility model adopts a long triangular design, which allows the support to extend into both ends of the core film when winding a core film with a larger diameter, so that the yarn can fit better with the core film and at the same time reduce the size of the core film's polar holes, maintain the stability of the yarn width, and improve product quality.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] See Figures 1 to 4 .

[0023] A fiber winding nozzle device for improving yarn unfolding stability includes a gearbox 9, a fixed disc 4 rotatably connected to the gearbox 9, and a nozzle angle rotation motor 6 for driving the fixed disc 4 to rotate connected to the outside of the gearbox 9. Specifically, a motor mounting plate 7 is detachably connected to the gearbox 9, and the nozzle angle rotation motor 6 is mounted on the motor mounting plate 7 by bolts. More specifically, the motor mounting plate 7 has vertical grooves 21 at each of its four corners, and the motor mounting plate 7 is connected to the gearbox 9 by fixing bolts 22, the bottom ends of which pass through the vertical grooves 21. The motor mounting plate 7 is threadedly connected to the gearbox 9, and a washer 23 is placed between the motor mounting plate 7 and the fixing bolt 22. The motor mounting plate 7 of this utility model has vertical sliding grooves 21 on its four corners, so the vertical position of the screw nozzle angle rotary motor 6 can be adjusted as needed. When it is necessary to adjust the vertical position of the screw nozzle angle rotary motor 6, first loosen all the fixing bolts 22, then the motor mounting plate 7 can be adjusted to adjust the vertical position, and the vertical position of the screw nozzle angle rotary motor 6 will also change accordingly. When it is adjusted to the required position, tighten all the fixing bolts 22.

[0024] To ensure that the screw tip angle rotary motor 6 does not easily shift downward after being fixed, this invention also includes a fixing pressure plate 8 bolted to the gearbox 9. An anti-loosening bolt 31 is connected to the fixing pressure plate 8, and an adjusting nut 32 is threaded onto the anti-loosening bolt 31. The lower end of the anti-loosening bolt 31 vertically passes through the fixing pressure plate 8 and is threadedly connected to the motor mounting plate 7. The fixing pressure plate 8 is located above the motor mounting plate 7, and the adjusting nut 32 rests against the top of the fixing pressure plate 8. After the fixing pressure plate 8, anti-loosening bolt 31, and adjusting nut 32 are installed, this invention prevents the motor mounting plate 7 from shifting downward, thus ensuring that the screw tip angle rotary motor 6 does not easily shift downward during operation due to the downward movement of the motor mounting plate 7.

[0025] A support 2 is mounted on the fixed disc 4; the rear end of the support 2 is connected to the fixed disc 4, and a yarn nozzle 1 coaxial with the fixed disc 4 is mounted on the front half of the support 2. The yarn nozzle 1 is annular; two yarn guide combs 3 for guiding the yarn are also connected to the rear side of the yarn nozzle 1 on the support 2; specifically, the support 2 is elongated triangular (see reference). Figure 1In this invention, the length of both sides of the long triangle is greater than the length of the base. Preferably, the support 2 is an isosceles triangle, and a circular hole 11 is provided in the middle of the support 2 to reduce its own weight. The nozzle 1 of this invention is annular, and the nozzle 1 is coaxial with the fixed disc 4. Therefore, the curvature of the nozzle 1 remains unchanged at any angle during any change in angle. When the yarn changes angle through the fiber winding machine, the position of the yarn at the nozzle 1 shifts due to the change in winding angle. The unchanged curvature of the annulus ensures that the yarn can be fully unfolded at any angle. At the same time, the yarn position is stabilized and fixed by the guide comb 3, so that the yarn maintains the unfolded width at any position when the fiber winding machine changes angle, thus improving product quality.

[0026] The support 2 has an elongated triangular design, which allows it to extend deeper into both ends of the core film when winding a core film with a larger diameter. This allows the yarn to adhere better to the core film, while reducing the size of the core film's aperture, maintaining the stability of the yarn width, and improving product quality. The elongated triangular support 2 has three round holes 11 in the middle to reduce its own weight. Preferably, the nozzle 1 is installed at the front end of the support 2, which allows it to penetrate deeper into the core film when reaching both ends, maintaining the fit between the yarn and the core film and improving product quality.
