Description

Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, in particular to a novel upper spindle frame for a high-speed braiding machine. Background Art

[0002] Most ordinary high-speed braiding machines are Japanese-style spindle racks, and their tension method uses a ratchet brake + disc spring to generate tension. However, the wire-releasing tension of this spindle is not linear. When releasing the wire, there is friction between the pawl and the ratchet, and the vibration is large. In order to overcome the influence of centrifugal force on the wire release of the spindle rack, a new tension system and overall structure are designed. Utility Model Content

[0003] The purpose of the utility model is to provide a novel spindle frame for a high-speed braiding machine, which increases structural stability, facilitates the replacement of spindles, subdivides the tension and makes it easier to adjust the wire release tension, thereby overcoming the influence of centrifugal force on the spindle frame tension.

[0004] According to the utility model, a new type of upper spindle frame for a high-speed braiding machine includes an upper spindle frame body, a mounting plate is fixed on the top of the upper spindle frame body, a wire feeding mechanism is installed on the mounting plate, the upper spindle frame body is provided with two opposite sides, cantilevers are respectively installed on both sides of the upper spindle frame, a wire spindle that can rotate around its own axis is movably installed between the two cantilevers, and a brake mechanism for controlling the rotation speed of the wire spindle is installed on the upper spindle frame body.

[0005] In actual use, after the wire spindle is installed in place, the wire starts from the wire spindle and passes through the wire feeding mechanism before exiting. In order to overcome the influence of centrifugal force on the tension of the upper spindle frame, the rotation speed of the wire spindle is adjusted by the brake mechanism.

[0006] Furthermore, the wire feeding mechanism includes a plurality of guide wheels which are sequentially mounted on the mounting plate and can rotate around their own axes, and the cable exits from the wire spindle after passing through the plurality of guide wheels sequentially.

[0007] Furthermore, the plurality of guide wheels are arranged in sequence from the bottom to the top of the mounting plate, and the guide wheel located at the bottom is close to the wire spindle.

[0008] Furthermore, the brake mechanism comprises:

[0009] Brake discs mounted on the cantilevers and rotatable around their own axes;

[0010] A brake belt is wound around the outside of the brake disc and connected to the side of the brake disc facing the other side;

[0011] A toggle assembly, mounted on the mounting plate, for lifting and releasing the brake belt;

[0012] The wire spindle is installed between the two brake discs;

[0013] When the shifting assembly pulls the brake belt, the brake belt fits tightly with the brake disc;

[0014] When the toggle assembly releases the brake belt, the brake belt moves away from the brake disc.

[0015] Furthermore, the toggle assembly includes:

[0016] Internal screw;

[0017] An outer screw is threadedly connected to the outer side of the inner screw, and a first end of the inner screw is exposed outside the outer screw;

[0018] A tension spring, one end of which is fixed to the mounting plate, and the other end of which is fixed to the second end of the inner screw;

[0019] A slide plate, the slide plate is movably mounted on the mounting plate, and the slide plate is fixed to the other end of the tension spring;

[0020] A lever is rotatably connected to the mounting plate. After the slide plate slides into position, the slide plate abuts against the first end of the lever and causes the lever to rotate. A protrusion is provided at the second end of the lever.

[0021] A brake rod, wherein a first end of the brake rod is connected to the brake belt, and the protrusion abuts against a second end of the brake rod.

[0022] During actual use, the inner screw is rotated to pull the tension spring. Since the tension spring and the slide plate are fixed, the slide plate will be pulled by the tension spring until the slide plate contacts the lever, causing the lever to rotate. After the lever is rotated into place, the protrusion abuts against the second end of the brake lever to pull the brake belt. Finally, the brake belt and the brake disc are fully fitted so that the rotation speed of the brake disc is adjusted.

[0023] Furthermore, a fixed top adapted to be snap-fitted with the wire spindle is fixed on the disc surface of the brake disc. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] Combination Figure 1 , shows a new type of upper spindle frame for a high-speed braiding machine of the utility model, including an upper spindle frame body 1, a mounting plate 2 is fixed on the top of the upper spindle frame body 1, a wire feeding mechanism is installed on the mounting plate 2, the upper spindle frame body 1 is provided with two opposite sides, cantilevers 3 are respectively installed on both sides of the upper spindle frame, a wire spindle that can rotate around its own axis is movably installed between the two cantilevers 3, and a brake mechanism for controlling the rotation speed of the wire spindle is installed on the upper spindle frame body 1.

[0028] In actual use, after the wire spindle is installed in place, the wire starts from the wire spindle and passes through the wire feeding mechanism before exiting. In order to overcome the influence of centrifugal force on the tension of the upper spindle frame, the rotation speed of the wire spindle is adjusted by the brake mechanism.

[0029] The wire feeding mechanism comprises a plurality of guide wheels 4 which are sequentially mounted on the mounting plate 2 and can rotate around their own axes. The cables are sequentially passed through the plurality of guide wheels 4 from the wire spindle and then come out.

[0030] A plurality of guide wheels 4 are arranged in sequence from the bottom to the top of the mounting plate 2, and the guide wheel 4 at the bottom is close to the wire spindle.

[0031] The brake mechanism includes:

[0032] Brake discs 5 mounted on the cantilever arms 3 and rotatable around their own axes;

[0033] The brake belt 6 is wound around the outside of the brake disc 5 and connected to the side of the brake disc 5 facing the other side;

[0034] A toggle assembly, mounted on the mounting plate 2, for pulling and releasing the brake belt 6;

[0035] A wire spindle is installed between the two brake discs 5;

[0036] When the assembly is pulled up by the toggle, the brake belt 6 is closely fitted to the brake disc 5;

[0037] When the toggle assembly releases the brake belt 6 , the brake belt 6 moves away from the brake disc 5 .

[0038] The toggle assembly includes:

[0039] Internal screw 7;

[0040] The outer screw rod 8 is screwed to the outer side of the inner screw rod 7, and the first end of the inner screw rod 7 is exposed outside the outer screw rod 8;

[0041] A tension spring 9, one end of which is fixed to the mounting plate 2, and the other end of which is fixed to the second end of the inner screw 7;
