Description

Technical Field

[0001] This invention relates to the field of braiding machine manufacturing, and more specifically to a modular braiding machine rotor support. Background Technology

[0002] In existing market braiding machines, a gear combination operates in a circle. A dial rotor is located at the corresponding position of the gear. There are several notches on the dial rotor surface. Each notch is equipped with a spindle seat corresponding to the left and right tracks of the panel. The raw yarn spindle for braiding ropes is mounted on the spindle seat. After the equipment is started, the gear transmission drives the spindle seat on the dial to move in a cross circle according to the left and right tracks, so as to obtain the cross braided fabric.

[0003] Currently, the runway is designed with several support structures installed on a workbench. The outer side of the support structure has matching inserts with corresponding gaps between the inserts and the support structure. Since there is no reference positioning between the inserts and the support structure, the installation accuracy requirements are very high in order to ensure consistent gaps, which makes assembly difficult and inefficient for workers. Moreover, in the past, powder metallurgy or cast iron was used to process the support structure, which was difficult and heavy. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a modular braiding machine rotor support, which features an ingenious design, a reasonable and compact structure, light weight, easy assembly, and high precision.

[0005] The technical solution of the present invention:

[0006] The modular braiding machine rotor support body is installed on the worktable of the braiding machine. It includes a dial rotor, a support body, an intermediate shaft, and a drive gear. The dial rotor is installed on the upper end of the intermediate shaft, and the support body is rotatably installed on the outer side of the intermediate shaft near the center. The drive gear is installed on the lower end of the intermediate shaft. The support body is designed as a disc and has an annular rib designed on the lower end of the outer side of the support body. The support body is made of plastic material and is integrally processed.

[0007] The support body has a built-in bearing in the middle, which is mounted on the central rotating shaft. The support body is installed on the workbench below.

[0008] The rotor has a mounting hole in the middle, which is an internal gear-shaped hole. An external gear-shaped locking block is provided at the circumference of the middle shaft near the upper end, and the locking block is locked in the mounting hole.

[0009] The bearing has an extended annular convex journal on the upper circumference of its inner ring, and the upper end of the annular convex journal supports the underside of the dial rotor.

[0010] The upper end of the intermediate shaft is also provided with an annular protrusion, which blocks the top of the dial rotor.

[0011] The drive gear has a polygonal hole in the middle, and the lower end of the intermediate shaft is correspondingly provided with a polygonal protrusion. The polygonal protrusion of the intermediate shaft is fitted into the polygonal hole of the drive gear.

[0012] The intermediate pivot is designed as a hollow pivot that runs through the top and bottom.

[0013] The support body has an inner annular groove on the inner side of the inner hole for assembling the outer ring of the bearing. The inner annular groove also has several annular protrusions. The outer circumferential surface of the bearing has several outer annular grooves. The several outer annular grooves and the several annular protrusions interlock with each other. The support body is formed directly on the outside of the bearing by injection molding.

[0014] The support body has a downward-protruding annular boss at its lower middle end. Several mounting holes are also designed on the support body. The annular boss engages with pre-drilled holes on the worktable, and the support body is fixed to the worktable with bolts passing through the mounting holes. An insert is also installed on the worktable on the outer side of the support body, blocking the outer side of the annular rib. The gap between the outer side of the support body and the insert forms a raceway for the spindle seat of the braiding machine. Alternatively, the worktable has a panel with pre-drilled mounting slots corresponding to several modular braiding machine rotor supports. The support body is located within these mounting slots, forming a raceway between the support body and the mounting slots. The dial rotor is located above the worktable or panel, and the drive gear is located below the worktable.

[0015] The lower end of the inner ring of the bearing is provided with a retaining ring that is attached to the outside of the intermediate rotating shaft; the upper and lower ends of the drive gear are respectively designed with a retaining ring that is attached to the outside of the intermediate rotating shaft.

[0016] The advantages of this invention are:

[0017] The outer side of the support structure is designed with ring-shaped ribs, which facilitates precise positioning of the runway, makes assembly convenient, and improves efficiency;

[0018] The support body can be molded separately from the bearing, or the support body can be injection molded as a whole on the outside of the bearing. It is easy to process, low in cost, low in friction, convenient for assembly and later maintenance and replacement. The injection molding one-piece effect is better, saves processes and has low energy consumption.

[0019] The support body is rotatably connected to the central shaft via a bearing, and the convex journal on the inner ring of the bearing directly supports the underside of the dial wheel rotor. The weight of the spindle seat and the upper spindle acts on the dial wheel rotor, which then transmits the weight to the bearing through the convex journal. The bearing and the support body cooperate to form an integrated support, and the support body transmits the force to the worktable. At the same time, the radial alternating inertial force generated when the spindle seat and the upper spindle move is transmitted from the spindle seat to the dial wheel rotor, from the dial wheel rotor to the central shaft, from the central shaft to the bearing, from the bearing to the support body, and finally from the support body to the worktable. This invention greatly improves the resistance to radial alternating forces, improves the overall static accuracy and planar accuracy, and reduces the difficulty and cost of parts processing.

[0020] The gear rotor and drive gear are positioned by gear-shaped or polygonal structures designed in this invention, which facilitates processing and assembly and improves fitting accuracy.

[0021] The central pivot is designed as a hollow pivot, with a through hole in the middle that can serve as a passageway for the weaving material.

[0022] The invention adopts a modular structure and is designed and formed separately. The structure of the invention enables rapid and accurate positioning and assembly, with high precision and efficiency, meeting the needs of production and processing. Attached Figure Description

[0033] See attached document Figure 1-10 The modular braiding machine rotor support body is installed on the worktable 100 of the braiding machine. It includes a dial rotor 1, a support body 2, an intermediate shaft 3, and a drive gear 4. The dial rotor 1 is mounted on the upper end of the intermediate shaft 3, and the support body 2 is rotatably mounted on the outer side of the intermediate shaft 3 near the center. The drive gear 4 is mounted on the lower end of the intermediate shaft 3. The support body 2 is designed as a disc with an annular rib 21 at the lower end of its outer circumference. The support body 2 is integrally molded from plastic. The plastic design of the support body and its rotatable support of the intermediate shaft improves the stress distribution on the dial rotor during operation and enhances overall rigidity. The annular rib on the outer side of the support body ensures that external inserts or entire panels can be directly assembled with the support body. Simply placing the support body against the outer side of the annular rib ensures precise positioning, eliminates unnecessary adjustments, and is simple, convenient, and quick, saving assembly time.

[0034] like Figure 2 The support body 2 has a built-in bearing 5, which is mounted on the central rotating shaft 3. The support body 2 is mounted on the worktable 100. The bearing provides radial rotational support, reducing friction and noise, and meeting the requirements for high-speed rotation. The bearing can be a rolling bearing; the view shown in this invention depicts a double-row rolling bearing, but it is not limited to the embodiments shown. The support body is directly mounted on the worktable for force transmission and distribution.

[0035] like Figure 3 As shown in Figure 4, the rotary rotor 1 has a mounting hole 11 in the middle, which is an internal gear-shaped hole. An external gear-shaped locking block 31 is correspondingly provided at a position around the upper end of the central rotating shaft 3, and the locking block 31 is locked into the mounting hole 11. This design allows for convenient and quick assembly, saves production time, and achieves high assembly precision.

[0036] like Figure 2 as well as Figure 7-9 The bearing 5 has an extended annular convex journal 51 around its upper inner ring, with the upper end of the annular convex journal 51 supporting the underside of the dial rotor 1. Since the annular convex journal directly supports the dial rotor, the downward force on the dial rotor is directly transmitted to the bearing. The bearing then distributes the force to the worktable through the outer support, improving the overall structural load-bearing capacity. Simultaneously, the annular convex journal increases the radial load-bearing capacity of the intermediate shaft.

[0037] like Figure 2 as well as Figure 4The upper end of the intermediate rotating shaft 3 is also provided with an annular protrusion 32, which blocks the top of the dial rotor 1. The annular protrusion design prevents the dial rotor from falling off the upper end of the intermediate rotating shaft, which is a safety design.

[0038] like Figure 4 and Figure 5 The drive gear 4 has a polygonal hole 41 in the middle, and the lower end of the intermediate shaft 3 is correspondingly provided with a polygonal protrusion 33. The polygonal protrusion 33 of the intermediate shaft 3 is fitted into the polygonal hole 41 of the drive gear 4. This design enables quick and precise assembly, saves time, and ensures quality.

[0039] The intermediate shaft 3 is designed as a hollow shaft that runs vertically through the shaft. The through hole in the middle of the intermediate shaft can serve as a passage for the woven material.

[0040] like Figure 2 , Figure 6 , Figure 7 The support body 2 has an inner annular groove 22 on the inner side of its inner hole for assembling the outer ring of the bearing 5. The inner annular groove 22 also contains several annular inner protrusions 23. Correspondingly, the outer circumferential surface of the bearing 5 has several outer annular grooves 52, which interlock with the annular inner protrusions 23. The support body 2 is directly injection molded onto the outside of the bearing 5. This design integrates the support body and bearing into a single unit, facilitating installation and providing radial rotational support and axial load-bearing capacity, thus enhancing the overall structural strength.

[0041] like Figure 2 , Figure 8 , Figure 9 , Figure 10The support body 2 has a downward-protruding annular boss 24 at its lower middle end. The support body 2 also has several mounting holes 11. The annular boss 24 engages with a pre-drilled circular hole on the workbench 100. The support body 2 is then fixed to the workbench 100 by bolts passing through the mounting holes 11. (This annular boss design allows for quick engagement with the pre-drilled hole on the workbench, and its extended shape effectively encloses the bearing, forming a unified structure.) An insert is also provided on the outer side of the support body 2. 6 is installed on the workbench 100, with the insert 6 locking onto the outside of the annular rib 21. This creates a raceway 7 for the spindle seat of the braiding machine between the outer side of the support body 2 and the insert 6. Alternatively, the workbench 100 can have a full panel 8, with mounting slots pre-set for several modular braiding machine rotor supports. The support body 2 is located within these mounting slots, forming a raceway between the support body 2 and the mounting slots. The dial rotor 1 is located above the workbench 100 or the panel, and the drive gear 4 is located below the workbench 100. The existing technology uses an insert assembly design on the outside of the support body or an overall panel opening design to form a raceway on the outside of the support body. However, with the annular rib design, there is no need for positional installation and adjustment of the insert or panel opening; the insert can be directly snapped onto the outside of the annular rib for splicing, or the entire panel can be snapped onto the annular rib, achieving rapid and precise assembly. For example, in patent CN202111498477.3, the inserts in the disclosed runway module are positioned by the cooperation of slots and blocks, and a disc-shaped slot block is also required for positioning. However, in this invention, there is no need for slots and blocks for positioning. This eliminates the need for slots and blocks when processing the inserts, reducing processing difficulty and improving processing quality. At the same time, the disc-shaped slot block is not a necessary component. The schematic diagram of this invention shows a reserved mounting port for the disc-shaped slot block, which is only one embodiment shown.

[0042] like Figure 2 The lower end of the inner ring of the bearing 5 is provided with a retaining circlip that is secured to the outside of the intermediate rotating shaft 3; the upper and lower ends of the drive gear 4 are respectively designed with retaining circlips that are secured to the outside of the intermediate rotating shaft 3. The retaining circlip design is to prevent the structure from loosening after assembly and is existing technology. This invention is briefly described below.

[0043] In use, the support body is mounted on the worktable of the knitting machine. A rotating wheel is mounted on the upper end of the intermediate shaft. The intermediate shaft then passes through a bearing in the middle of the support body for a fixed connection. The upper convex journal of the inner ring of the bearing rests against the protruding tooth block of the gear-shaped hole in the middle of the rotating wheel rotor, and works in conjunction with the annular protrusion on the intermediate shaft to fix and support the rotating wheel rotor vertically. A drive gear is fixedly mounted on the lower end of the intermediate shaft. When assembling inserts or integral panels on the outer circumference of the support body, they can be directly and quickly snapped onto the outer side of the annular protrusion of the support body for precise positioning without adjustment. Assembly forms a running track, improving assembly efficiency. The support body is fixedly installed on the worktable, and the intermediate shaft is rotatably installed in the support body through the bearing. The support body provides both rotational support for the intermediate shaft and axial support for the intermediate shaft. During operation, the spindle seat 110 is installed in the raceway and is clamped on the dial wheel rotor. The drive gear rotates to drive the intermediate shaft to rotate. The support body is injection molded on the outside of the bearing to form an integral part. The intermediate shaft is installed in the inner hole of the inner ring of the bearing to provide rotational support for the intermediate shaft. The convex journal at the upper end of the inner ring of the bearing is supported below the inner teeth of the gear-shaped hole of the dial wheel rotor. The operation is smooth and the structure has high strength.
