[0041] Example 1
[0042] like Figures 1-11 As shown, the utility model provides a braiding machine platform for braiding a single-end closed stent, comprising:
[0043] Rack 1;
[0044] A disc assembly is mounted on a frame 1. The disc assembly includes a base disc 1-2, a guide rail disc 1-3, and a fixed disc 1-9, which are connected in sequence from bottom to top. A cross guide rail is provided on the surface of the guide rail disc 1-3. The cross guide rail is a closed guide rail channel structure composed of multiple "8"-shaped track modules connected in a ring shape. A central tube 1-10 is provided at the center of the fixed disc 1-9. The central tube 1-10 is connected to a conductor head 1-11, which controls the core shaft to keep it moving in the braiding center during braiding. An annular cavity is provided between the base disc 1-2 and the guide rail disc 1-3.
[0045] A power group, the power group includes a dial gear group 1-7 located below the cross guide rail, an intermediate gear 1-6 connected to the dial gear group 1-7, and a power motor 1-4 driving the intermediate gear 1-6, and the power motor 1-4 is provided with a motor gear 1-5; wherein the dial gear group 1-7 and the intermediate gear 1-6 are both located in the annular cavity between the base plate 1-2 and the guide rail plate 1-3; the dial gear group 1-7 includes a plurality of annularly connected dial gear assemblies, the dial gear group 1-7 just corresponds to the cross guide rail of the guide rail plate 1-3, and the dial gear assembly includes a dial plate 1-7-11, a dial gear 1-7-5, a locking nut 1-7-3, and an adjusting washer 1-7 which are assembled and connected in sequence from top to bottom. -2, a first bearing 1-7-10 and a first pressure sleeve 1-7-9 are installed between the dial plate 1-7-11 and the dial gear 1-7-5, a second bearing 1-7-8, a third bearing 1-7-6 and a second pressure sleeve 1-7-7 are installed between the dial gear 1-7-5 and the locking nut 1-7-3, the dial plate 1-7-11, the dial gear 1-7-5, the locking nut 1-7-3 and the adjusting washer 1-7-2 are all installed on the dial shaft 1-7-1, and the dial shaft 1-7-1 is fixed to the base plate 1-2, an upper nut 1-7-13 is provided at the upper end of the dial shaft 1-7-1, and a lower nut 1-7-14 is provided at the lower end, and the dial gear 1-7-5 is meshed and connected with the intermediate gear 1-6.
[0046] The yarn carrying spindle assembly 1-8 comprises a yarn carrying spindle 1-8-1, a spindle seat 1-8-2, and at least two guide blocks 1-8-3 connected in sequence from top to bottom, wherein the guide blocks 1-8-3 are connected to the dial gear set 1-7 for transmission;
[0047] The traction mechanism 2 includes a traction module 2-1 mounted on a frame, a motion slider 2-2 mounted on the traction module 2-1, the motion slider connected to a bracket, and the bracket 2-3 connected to a locking chuck 2-4. The traction module 2-1 is a vertically arranged linear motion module. The locking chuck 2-4 can lock the components after clamping.
[0048] The wire hanging tool 3 is connected to the traction mechanism 2.
[0049] The dial gear 1-7-5 has an inner cavity, and the locking nut 1-7-3 is fixed to the bottom of the dial gear 1-7-5 through the screw pin 1-7-4. The second bearing 1-7-8, the third bearing 1-7-6 and the second pressure sleeve 1-7-7 between the dial gear 1-7-5 and the locking nut 1-7-3 are enclosed in the inner cavity inside the dial gear 1-7-5.
[0050] There are two guide blocks 1-8-3, and both guide blocks 1-8-3 are connected to the spindle base 1-8-2 through the guide block shaft. The two guide blocks can rotate on the spindle base 1-8-2.
[0051] Each dial plate 1-7-11 is connected to only one spindle carrying assembly 1-8, and one side of each of the dial plates 1-7-11 is connected to two guide blocks 1-8-3 of the spindle carrying assembly 1-8.
[0052] Since each "8"-shaped track module is composed of an S-shaped forward guide rail module and an S-shaped reverse guide rail module, the cross guide rail includes a curved forward guide rail formed by multiple forward guide rail modules and a curved reverse guide rail formed by multiple reverse guide rail modules. The multiple yarn carrying spindle assemblies 1-8 are evenly distributed on the forward guide rail and reverse guide rail of the guide rail plate 1-3, with half distributed in each of the forward and reverse directions. In this way, the yarn carrying spindles of two different guide rails will make an "8"-shaped cross motion on the dial plate 1-7-11.
[0053] The wire hanging tool 3 includes a support core shaft 3-1 connected to the locking chuck 2-4, an adjusting rod 3-2 sleeved inside the support core shaft 3-1, and a plurality of hanging needles 3-4 are provided on the radial circumference of the surface of the support core shaft 3-1. Figure 11 As shown, the silk carried by the multiple spindle assemblies 1-8 is connected to the hanging needle 3-4. The support core shaft 3-1 and the adjusting rod 3-2 are fixedly connected by a fixing pin 3-3.
[0054] Working principle of the present invention:
[0055] The yarn is pulled out from a yarn-carrying spindle 1-8-1 on the positive guide rail of the cross guide rail of the guide rail disk 1-3, and the yarn is wound on the yarn-carrying spindle 1-8-1 on the adjacent reverse guide rail through the hanging needle 3-4 on the hanging tool 3, so that the yarns of multiple groups of yarn-carrying spindles 1-8-1 are hung on the hanging needle 3-4.
[0056] The power motor 1-4 and the intermediate gear 1-6 drive the dial gear set 1-7 to move, and at the same time, it will carry multiple groups of spindle assemblies 1-8 to make "8"-shaped cross motion on the cross guide rail. At the same time, the traction mechanism 2 will carry the wire hanging tool 3 to move upward, so that the yarn carried by the spindle 1-8-1 will form a single-end closed mesh bracket on the bracket core shaft 3-1, such as Figure 12 As shown, the formation of single-end closure here is because a silk will pass through the hanging needle 3-4 on the hanging tool 3 to wrap the yarn around the adjacent carrying spindle 1-8-1.
[0057] Due to the adoption of the above-mentioned scheme, when the yarn-carrying spindle 1-8-1 is moving and weaving on the guide plate 1-3, the power motor 1-4 drives the dial gear set 1-7 to rotate according to a pre-set program, and at the same time drives the yarn-carrying spindle 1-8-1 to make an "8" cross motion trajectory to realize the cross-weaving of the yarn; the traction action of the traction mechanism 2 causes the yarn to make an "8" cross motion around the bracket core shaft 3-1, and finally is woven into a product, completely replacing the manual weaving process and realizing an automated weaving platform.
[0058] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
