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

[0023] See also Figure 1-3The utility model provides a technical solution: a novel spindle device for a braiding machine, comprising a base 1, a mounting groove 2 is provided on the top of the base 1, a yarn drum body 3 is plugged into the inner side of the mounting groove 2, a limiting disk 4 is fixedly connected to the outer side of the yarn drum body 3, a stabilizing component 500 for limiting and stabilizing the yarn drum body 3 is installed on the top of the base 1, and a plug-in component 600 for installing the yarn drum body 3 is installed inside the base 1; through the coordinated use of the yarn drum body 3 and the stabilizing component 500 at the top of the base 1 and the plug-in component 600 on the inside, the spindle can be easily removed for maintenance while ensuring its working stability, and through the limiting and abutting effects between the structures, the spindle can continuously maintain a stable state during operation, and at the same time, it will not consume too much time and energy during disassembly, which is convenient for the normal operation, thereby effectively improving the practicality and convenience of use of the braiding machine spindle.

[0024] It should be noted that the bobbin body 3 is composed of two disc blocks and a bobbin rod rotatably connected between opposite sides of the two disc blocks through a bearing, so that the bobbin rod can rotate between opposite sides of the two disc blocks.

[0025] In this embodiment, the stabilizing assembly 500 is a structure used to keep the overall structure of the spindle stable and convenient for disassembly.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the stabilizing assembly 500 includes a fixing plate 501 abutting against the top of the base 1, a yarn guide rod 502 is fixedly installed on the top of the fixing plate 501, a square block 503 is fixedly connected to the bottom of the fixing plate 501, a square groove 504 for the square block 503 to be inserted is provided on the top of the base 1, four fastening bolts 505 are penetrated on the top of the fixing plate 501, the top of the yarn guide rod 502 is fixedly connected to a limiting plate 506, the bottom of the limiting plate 506 is fixedly connected to a spring 507, and the bottom of the spring 507 is fixedly connected to a spring located outside the yarn guide rod 502. The sliding cylinder 508 on the side can play the role of elastic support for the sliding cylinder 508 under the action of the spring 507, and can exert downward pressure on it without hindering the rotation of the sliding cylinder 508. The front side of the sliding cylinder 508 is threadedly connected with a hand screw 509, and the right side of the sliding cylinder 508 is fixedly connected with a connecting rod 510, and the right end of the connecting rod 510 is fixedly connected with a limiting cylinder 511. The top of the yarn tube body 3 is fixedly connected with a limiting block 512, and the top of the limiting block 512 is abutted with a top plate 513, and the bottom of the top plate 513 is fixedly connected with a threaded rod 514.

[0027] It should be noted that the top of the base 1 is provided with four internal threaded holes for threaded connection of four fastening bolts 505 respectively. Through the cooperation between the fastening bolts 505 and the internal threaded holes, the fixing plate 501 can be stably fixed on the top of the base 1. A plurality of yarn guide wheels are fixedly installed on the outer side of the yarn guide rod 502. The yarn guide wheels and the yarn guide rod 502 are rotatably connected, so that the yarn can be guided and transported through the yarn guide wheels.

[0028] In addition, the inner side of the sliding cylinder 508 and the outer side of the yarn guide rod 502 are slidably connected, so that the sliding cylinder 508 can slide smoothly on the outer side of the yarn guide rod 502, and the end of the hand screw 509 is in contact with the outer side of the yarn guide rod 502, and the sliding cylinder 508 can be positioned by the hand screw 509. The top and bottom of the limiting cylinder 511 are both open, and the inner side of the limiting cylinder 511 is in contact with the outer side of the limiting block 512. The height of the limiting cylinder 511 is equal to the height of the limiting block 512, so that the limiting cylinder 511 can be moved to the outer side of the limiting block 512 to limit it.

[0029] At the same time, a threaded groove for threaded connection of the threaded rod 514 is opened on the top of the limit block 512, so that the threaded rod 514 can be threadedly connected to the inner side of the threaded groove, thereby blocking and limiting the limit cylinder 511. At this time, under the cooperation between the limit cylinder 511 and the limit block 512, the yarn tube body 3 can be limited. Under the action of the threaded rod 514 and the top plate 513, the position of the limit cylinder 511 can be limited. Under the action of the hand screw 509, the position of the sliding cylinder 508 can be limited, thereby playing a stable limiting role on the yarn tube body 3 through the cooperation between the structures.

[0030] In this embodiment, the plug-in assembly 600 is a structure used for plug-in positioning.

[0031] like Figure 1 and Figure 2 As shown, the plug-in assembly 600 includes a friction pad 601 bonded to the inner side of the installation slot 2, two polygonal rods 602 are fixedly connected to the bottom of the yarn tube body 3, and two polygonal cavities 603 connected to the inside of the installation slot 2 are opened inside the base 1.

[0032] It should be noted that the outer side of the bottom end of the yarn tube body 3 is fitted with the inner side of the friction pad 601. The friction pad 601 is a nylon pad, and can also be a rubber pad or other anti-slip structure, which can play an anti-slip protection role for the outer side of the yarn tube body 3. The two polygonal cavities 603 can be used for the two polygonal rods 602 to be plugged in respectively. The cooperation between the two polygonal cavities 603 and the two polygonal rods 602 can play a positioning role for the yarn tube body 3.

[0033] The working principle of the above embodiment is:

[0034] When yarn processing and production is required, the yarn tube body 3 is inserted into the inner side of the installation groove 2, so that the two polygonal rods 602 are respectively inserted into the inside of the two polygonal cavities 603. At the same time, under the action of the friction pad 601, the friction between the outer sides of the bottom ends of the yarn tube body 3 can be increased. The square block 503 is inserted into the inner side of the square groove 504, and the fastening bolt 505 is turned to connect the fixing plate 501 with the top of the base 1. The limit cylinder 511 is moved to the outer side of the limit block 512, and the top plate 513 is turned so that the threaded rod 514 is threadedly connected to the limit block 512. The top of the block 512 is pressed and limited by the top plate 513 to limit the limiting cylinder 511 and the limiting block 512. The installation work can be completed by tightening the hand screw 509. When the yarn drum body 3 needs to be maintained, the hand screw 509 is loosened, the top plate 513 is rotated to keep it away from the limiting block 512, the sliding cylinder 508 is moved upward, and the sliding cylinder 508 is rotated to the front side or the back side to keep the limiting cylinder 511 away from the limiting block 512. The yarn drum body 3 can be pulled upward to be moved out from the inner side of the installation groove 2, so as to facilitate the maintenance work on it.

[0035] Compared with the prior art, the novel spindle device of the braiding machine, through the coordinated use of the yarn tube body 3 on the top of the base 1 and the stabilizing component 500 as well as the plug-in component 600 on the inside, can ensure the working stability of the spindle while being convenient to remove for maintenance. Through the limiting and abutting effects between the structures, the spindle can continuously maintain a stable state during operation, and at the same time, it will not consume too much time and energy when disassembling, which facilitates the normal operation of the work, thereby effectively improving the practicality and ease of use of the spindle of the braiding machine, and solving the problem that the spindle of the existing braiding machine can ensure stability during operation but is not easy to disassemble and maintain.
