Description
Technical Field
[0001] This utility model belongs to the field of Bondi thread processing technology, specifically relating to automatic Bondi thread twisting equipment. Background Technology
[0002] Bonded wire is a flexible tubing made of multiple extremely fine metal wires tightly wound together. One of the core processes in its manufacturing is "twisting." The twisting process involves winding multiple monofilaments around a central line or between each other at a specific helical angle and twist pitch to form a composite tubing that combines flexibility, compressive strength, and sealing properties.
[0003] However, in the actual preparation process, in order to ensure that each monofilament maintains constant tension and accurate relative position during twisting, the equipment usually needs to be equipped with an independent yarn guide, tensioner, or even pre-twist device for each monofilament. The structure is relatively complicated, and the equipment occupies a lot of space and costs a lot. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] like Figures 1 to 4 The automatic twisting and forming equipment for Bondi yarn shown includes a base plate 1, a fixed column 2 on the top left side of the base plate 1, a large gear 3 on the fixed column 2, a rotating shaft 4 on the right side of the fixed column 2, a linkage shaft 5 on the rotating shaft 4, a first coupling 6 on the front side of the linkage shaft 5, a first set of thread rods 7 on the right side of the first coupling 6, a second coupling 8 on the rear side of the linkage shaft 5, a second set of thread rods 9 on the right side of the second coupling 8, a fixed frame 10 on the top right side of the base plate 1, a twisting wheel 11 rotatably mounted between the fixed frames 10, and a wire groove 12 on the twisting wheel 11; both the first coupling 6 and the second coupling 8 have... There is a small gear 13 that meshes with a large gear 3; a heating module 14 is provided on the twisting wheel 11; a guide plate 15 is provided on the right side of the rotating shaft 4, and guide holes 16 are provided on both the front and rear sides of the guide plate 15; a wire hole 17 is provided through the fixed column 2 and the rotating shaft 4; the wire hole 17 is located at the midpoint of the guide hole 16, and the wire hole 17 and the guide groove 12 are on the same horizontal line; a stator winding 18 is provided on the right side of the fixed column 2, and an annular rotation space 19 is formed between the stator winding 18 and the outer wall of the fixed column 2; a rotor 20 is fixedly connected to the left side of the rotating shaft 4, and the rotor 20 is rotatably located within the annular rotation space 19.
[0025] This invention utilizes the meshing structure of the linkage shaft 5, the small gear 13, and the large gear 3 to achieve synchronous revolution and rotation of multiple monofilaments, ensuring that the monofilaments converge at a constant tension and uniform angle during winding, thus guaranteeing uniform and tight winding. It reduces reliance on independent yarn guides, tensioners, and pre-twisting devices, simplifying the equipment structure. The twisting wheel 11 integrates a heating module 14, which can perform heat-melting and shaping treatment on the hot-melt yarn and monofilaments after winding, improving the structural stability and durability of the bonded yarn. Furthermore, the threading hole 17, the conductor hole 16, and the conductor groove 12 are on the same horizontal line, ensuring that the hot-melt yarn and monofilaments converge at the same point and angle, avoiding deviation and improving the controllability and consistency of the twisting process.
[0026] Example 2
[0027] like Figures 1 to 4 The automatic twisting and forming equipment for Bondi wire shown includes a base plate 1, a fixed column 2 on the top left side of the base plate 1, a large gear 3 on the fixed column 2, and a rotating shaft 4 on the right side of the fixed column 2. A threading hole 17 is provided between the fixed column 2 and the rotating shaft 4. Specifically, a discharge structure for hot melt wire can be set on the left side of the base plate 1. The hot melt wire passes through the threading hole 17 to the right, so that it is in the center position and does not affect the rotation of the rotating shaft 4.
[0028] The rotating shaft 4 is equipped with a linkage shaft 5. A first coupling 6 is rotatably mounted on the front side of the linkage shaft 5. A first set of wire rods 7 is mounted on the right side of the first coupling 6. A second coupling 8 is rotatably mounted on the rear side of the linkage shaft 5. A second set of wire rods 9 is mounted on the right side of the second coupling 8. It can be understood that the rotation of the rotating shaft 4 drives the first coupling 6 and the second coupling 8 to rotate through the linkage shaft 5. When the staff places the monofilament spool on the first set of wire rods 7 and the second set of wire rods 9 in advance, the pulled-out monofilament spool can be driven to wind around the hot melt wire.
[0029] Both the first coupling 6 and the second coupling 8 have a small gear 13 on their left sides, which meshes with the large gear 3. When the rotating shaft 4 rotates and drives the linkage shaft 5 to rotate, the small gear 13 can revolve around the large gear 3. At the same time, the small gear 13 rotates on its own axis due to its meshing with the large gear 3. This allows the monofilaments on the first set of wire rods 7 and the second set of wire rods 9 to be stretched while simultaneously winding the hot melt wire, further increasing the twisting quality of the bonded yarn.
[0030] A guide plate 15 is provided on the right side of the rotating shaft 4. Guide holes 16 are provided on both the front and rear sides of the guide plate 15. That is, the staff needs to pass the monofilament end on the monofilament spool through the guide hole 16 on the guide plate 15 in advance, and then pull it forward to gather to the outside of the hot melt wire. The setting of the guide hole 16 can drive the monofilaments drawn from different positions on the monofilament spool to converge to the outside of the hot melt wire from the same point and at the same angle, so as to ensure the uniformity of twisting.
[0031] A fixing frame 10 is provided on the top right side of the base plate 1. A twisting wheel 11 is rotatably mounted between the fixing frames 10. A wire groove 12 is opened on the twisting wheel 11. The wire hole 17 is on the same horizontal line as the wire groove 12. The hot melt wire drawn out through the wire hole 17 enters the wire groove 12 horizontally. At the same time, the single wire enters the wire groove 12 from the wire hole 16 at the same angle. The winding and twisting of the wire is completed in the wire groove 12. The twisting wheel 11 is rotated by a drive component to drive the output of the bonded wire. An auxiliary structure is also set on the right side of the fixing frame 10 for the extraction of the bonded wire. It should be noted that the twisting wheel 11 is equipped with a heating module 14. After operation, it heats and melts the wound hot melt wire and single wire. After extraction, it is cooled and shaped to form the bonded wire.
[0032] Continuing from the above, to achieve the rotation of the rotating shaft 4, a stator winding 18 is also provided on the right side of the fixed column 2. An annular rotating space 19 is formed between the stator winding and the outer wall of the fixed column 2. A rotor 20 is fixedly connected to the left side of the rotating shaft 4. The rotor 20 is rotatably located in the annular rotating space 19. When the stator winding 18 is energized, a rotating magnetic field is established in the annular rotating space 19. The magnetic field acts on the rotor 20 and drives it to rotate synchronously, thereby driving the rotating shaft 4 and subsequent components to rotate, realizing the revolution and rotation of the single line.
[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
