Description

Technical Field

[0001] The utility model relates to the technical field of silk processing and production, in particular to a braided silk tensioning device. Background Art

[0002] The process of extracting silk from silk cocoons is generally called reeling. The extracted silk is thinner and has lower tensile resistance. During silk production, the extracted silk will be wound into thicker silk. This winding process is called braiding. As the braiding continues, the braided silk will be uniformly wound on rollers, and the rollers will play a storage role for the braided silk. After the braiding is completed, there is still a certain gap between the silk threads, which generally makes the silk threads fit more firmly.

[0003] The existing winding rollers have a relatively simple function and can only store the braided silk but cannot further tension the braided silk, resulting in tiny gaps between the strands of the braided silk.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1-3 As shown, a braided wire tensioning device comprises a support frame 1, a central shaft 2, an intermediate sleeve roller 3 and an arc-shaped outer plate 4, both ends of the central shaft 2 are rotatably mounted on the support frame 1, the interior of the intermediate sleeve roller 3 is hollow, the central shaft 2 is located at the inner axis position of the intermediate sleeve roller 3, and the outer surface of the central shaft 2 and the inner surface of the intermediate sleeve roller 3 are fixed by a connecting plate 21, that is, the central shaft 2 and the intermediate sleeve roller 3 can rotate together;

[0027] The surface of the middle roller 3 is evenly and evenly provided with a plurality of sets of sleeves 31 at equal intervals along the length direction of the middle roller 3. Each set of sleeves 31 is evenly and evenly distributed around the surface of the middle roller 3 at equal intervals, and the inside of the sleeves 31 is hollow.

[0028] A plurality of arc-shaped outer plates 4 are evenly distributed around the outer surface of the middle sleeve roller 3 at equal intervals. Each arc-shaped outer plate 4 is arranged along the length direction of the middle sleeve roller 3. A plurality of slide bars 41 are evenly arranged on the inner surface of the arc-shaped outer plate 4. The plurality of slide bars 41 correspond to the positions of the sleeve 31. The slide bars 41 are connected to the sleeve 31 by plugging. The sleeve 31 plays a role of limiting support for the slide bars 41. The slide bars 41 can slide in the sleeve 31.

[0029] The surface of the central axis 2 is evenly and evenly provided with multiple groups of electromagnets 22 at equal intervals along the length direction of the central axis 2. Each group of electromagnets 22 is evenly and evenly distributed around the surface of the central axis 2 at equal intervals. The end of the slide bar 41 away from the arc-shaped outer plate 4 extends out of the sleeve 31 and approaches the electromagnet 22 on the central axis 2. The electromagnet 22 can generate magnetic thrust or magnetic attraction on the slide bar 41.

[0030] When the slide bar 41 moves outward, the six arc-shaped outer panels 4 can move outward, and the six arc-shaped outer panels 4 are slightly opened.

[0031] The connecting plates 21 are distributed along the length direction of the central axis 2, and there are six of them. The six connecting plates 21 are evenly spaced and distributed around the central axis 2 and the middle sleeve roller 3. Each group of sleeves 31 has six, and the six connecting plates 21 are staggered with each group of sleeves 31, that is, the positions of the connecting plates 21 and the sleeves 31 do not interfere with each other.

[0032] There are six arc-shaped outer plates 4, and the cross section of the arc-shaped outer plates 4 is annular. The arc-shaped outer plates 4, the central shaft and the intermediate rollers 3 are arranged concentrically; thus, when the central shaft 2 rotates, the intermediate rollers 3 and the arc-shaped outer plates 4 can rotate together. The length of the central shaft 2 is longer than the intermediate rollers 3 and the arc-shaped outer plates 4, so that the two ends of the central shaft 2 are just fixed on the support frame 1.

[0033] The lengths of the middle sleeve roller 3 and the arc-shaped outer plate 4 are consistent, which makes it convenient to wind the braided wire; a crossbeam 11 is arranged in the center of the support frame 1, and the crossbeam 11 is located directly below the arc-shaped outer plate 4, so that the structural strength of the entire support frame 1 is better; screw holes 12 are also symmetrically arranged on the bottom of the support frame 1, through which the entire device can be fixed on the ground or other equipment;

[0034] A motor is also provided at one end of the central shaft 2, which is fixed on the support frame 1. The driving shaft of the motor is connected to one end of the central shaft 2 through a coupling. The motor drives the central shaft 2, the middle sleeve roller 3 and the plurality of arc-shaped outer plates 4 to rotate together.

[0035] In summary: the central shaft 2, the middle sleeve roller 3 and the arc-shaped outer plate 4 rotate together, so that the braided wire can be wound on the multiple arc-shaped outer plates 4, and the braided wire moves back and forth on the arc-shaped outer plates 4, and the longer braided wire can be stored on the arc-shaped outer plates 4;

[0036] When the braided wire is wound around the arc-shaped outer plate 4, the electromagnet 22 is energized, and the electromagnet 22 generates a magnetic thrust on the slide bar 41, so that the slide bar 41 can slide outward in the sleeve 31, and the six arc-shaped outer plates 4 can move outward a short distance, and the radius of the cylindrical plate formed by the six arc-shaped outer plates 4 becomes slightly larger, so that the braided wire wound around the arc-shaped outer plate 4 is tensioned, so that the wires inside the braided wire can be more firmly attached, and the structural strength is higher;

[0037] After the wire is wound, the current passing through the electromagnet 22 is further increased, so that the six arc-shaped outer plates 4 move outward a greater distance, and the force to open the wound wire is greater, so that the inside of the wire can be further fitted more closely and further tightened.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
