Description

Technical Field

[0001] This invention relates to the field of rotary knitting machine technology, and in particular to a removable and replaceable knitting loop suitable for rotary knitting and its usage method. Background Technology

[0002] Rotary braiding machines can rapidly form composite material preforms by rotating yarn through a yarn carrier. The preforms formed by braiding reinforce composite materials, which are a new type of advanced composite material in the high-tech field. The fiber bundles are interwoven in different directions within the material to form an integral structure with excellent impact toughness, fatigue resistance, and ablation resistance. They can be used to manufacture high-temperature functional structural materials and can also be used for beams, frames, ribs, shafts, rods, and other components in structures such as wind turbine blades.

[0003] To alter the yarn interlacing state and adjust the weaving position during the weaving process, braiding rings are widely used to constrain the yarn, causing it to interlace and gather in advance to form a preform. Furthermore, the size of the braiding ring should not differ too much from the diameter of the mandrel (or the target preform size), otherwise uneven weaving will occur. Currently, braiding rings are fixed to the weaving equipment by welding or other methods, making it impossible to adjust them according to the actual target preform size. Moreover, once the braiding ring is fixed to the rotary weaving equipment, replacement is difficult, and the permissible preform size for weaving is also limited. Summary of the Invention

[0004] Purpose of the invention: To address the drawback that the radius of existing braided loops cannot be changed according to the size of the prefabricated body, this invention provides a replaceable braided loop suitable for rotary braiding and its usage method.

[0005] Technical Solution: To solve the above problems, the present invention adopts a removable and replaceable braided ring suitable for rotary braiding, including a removable braided ring module. The removable braided ring module includes a removable braided ring and a braiding base. Both the removable braided ring and the braiding base are provided with through holes for the core mold to pass through. The removable braided ring is composed of several braided ring units spliced ​​together, and the braiding base is composed of several braiding base units spliced ​​together. The bottom of the removable braided ring is provided with an arc-shaped bottom ring for constraining the yarn. The removable braided ring is fixedly connected to the braiding base, and the arc-shaped bottom ring is located in the through hole of the braiding base. When replacing or removing the braided ring, the removable braided ring is released from the braiding base, and then the removable braided ring is disassembled into several braided ring units and removed from both sides of the core mold.

[0006] Furthermore, the detachable braided ring includes two braided ring units. Each braided ring unit is provided with a connecting plate for connecting to the braided base. The arc-shaped bottom ring is fixedly connected to the connecting plate. When installing the detachable braided ring, the connecting plate abuts against the upper surface of the original braided ring, and the arc-shaped bottom ring is located inside the original braided ring.

[0007] Furthermore, the arc-shaped bottom ring has a first splicing groove on one side and a first splicing block that matches the first splicing groove on the other side. The first splicing block of one braided ring unit is inserted into the first splicing groove of another braided ring unit to complete the splicing of the detachable braided ring.

[0008] Furthermore, the braided base includes two braided base units. Each braided base unit includes a base groove for fixing the position of the braided base and a base body located inside the base groove. During installation, the base groove abuts against the lower surface of the original braided ring to fix the position of the braided base, and the base body is located inside the original braided ring.

[0009] Furthermore, the base body has a second splicing groove on one side and a second splicing block that matches the second splicing groove on the other side. The second splicing block of one woven base unit is inserted into the second splicing groove of another woven base unit to complete the splicing of the woven base.

[0010] Furthermore, the bottom of the arc-shaped bottom ring and the inner side of the bottom of the base body are rounded to reduce friction with the yarn.

[0011] Furthermore, the connecting plate and the base body are provided with several corresponding screw holes. The screw is installed in the screw holes to fix the detachable braided ring and the braided base. The two ends of the screw are fixed with bolts.

[0012] Furthermore, the base body is also provided with bolt countersunk holes, and the bolts on one side of the base body are installed in the bolt countersunk holes to avoid the bolts from getting tangled with the yarn.

[0013] Furthermore, it also includes the original braided ring, which is circular in shape and has a through hole in the middle for the core mold to pass through. The connecting plate abuts against the upper surface of the original braided ring, the base groove abuts against the lower surface of the original braided ring, and the arc-shaped bottom ring is installed in the through hole of the original braided ring.

[0014] The present invention also provides a method for using the above-mentioned removable and replaceable braided ring, comprising the following steps:

[0015] Step 1: Install the braided base; After assembling the braided base, push it in from below the original braided ring to fix the position of the braided base;

[0016] Step 2: Install the detachable braided ring; place the braided ring unit on both sides of the core mold and complete the splicing, with the upper surface of the detachable braided ring abutting against the upper surface of the original braided ring, and the arc-shaped bottom ring located inside the original braided ring;

[0017] Step 3: Assemble the detachable braided ring module; fix the detachable braided ring and the braiding base in place, and the radius of the arc-shaped bottom ring is the actual working radius of the detachable braided ring module during the braiding process;

[0018] Step 4: Replace the removable braided ring module; release the removable braided ring and braided base from the fixing, then disassemble the removable braided ring into several braided ring units and remove them from both sides of the core mold, replacing them with removable braided rings of different arc-shaped bottom ring radii.

[0019] Beneficial effects: Compared with the prior art, the significant advantages of this invention are (1) Installing a detachable braided ring module at the original braided ring position, changing the actual working radius of the braided ring by replacing the arc-shaped bottom ring with different radii, so that the radius of the braided ring can be changed according to the size of the prefabricated body, making the braiding more uniform and ensuring the braiding quality; (2) The detachable braided ring module is a splicing structure, spliced ​​on both sides of the core mold, so that the replacement of the braided ring can be carried out smoothly without being affected by the shape of the braid; (3) The positions where the detachable braided ring module contacts the yarn are all designed with rounded corners to reduce the friction with the yarn and facilitate the smooth braiding; (4) Designing bolt countersunk holes to avoid the bolts from getting tangled with the yarn and affecting the braiding.

[0026] like Figure 1 and Figure 2 As shown, this embodiment presents a removable and replaceable braided ring suitable for rotary braiding, comprising a removable braided ring module 1 and a primary braided ring 2. The primary braided ring 2 is annular, with a through hole in its center for a mandrel to pass through. The removable braided ring module 1 includes a removable braided ring 11 and a braiding base 12, both of which have through holes for a mandrel 3 to pass through. Figure 3As shown, the detachable braided ring 11 includes two braided ring units 13. Each braided ring unit has a connecting plate 16 for connecting to the braided base 12 and an arc-shaped bottom ring 15. The arc-shaped bottom ring 15 is fixedly connected to the connecting plate 16. The connecting plate 16 has screw holes evenly distributed along the circumference. During installation, the connecting plate 16 abuts against the upper surface of the original braided ring, and the arc-shaped bottom ring 15 is located inside the original braided ring. One side of the arc-shaped bottom ring 15 has a first splicing groove 151, and the other side has a first splicing block 152 that matches the first splicing groove 151. The first splicing block 152 of one braided ring unit 13 is inserted into the first splicing groove 151 of the other braided ring unit 13 to complete the splicing of the detachable braided ring 11.

[0027] like Figure 4 and Figure 5 As shown, the braided base 12 includes two braided base units 14. Each braided base unit 14 includes a base groove 17 for fixing the position of the braided base 12 and a base body 18 located inside the base groove 17. During installation, the base groove 17 abuts against the lower surface of the original braided ring 2 to fix the position of the braided base 12, and the base body 18 is located inside the original braided ring 2. The base body 18 has screw holes corresponding to the screw holes on the connecting plate 16, and the bottom surface of the screw holes of the base body 18 also has bolt countersunk holes 183. One side of the base body 18 has a second splicing groove 181, and the other side has a second splicing block 182 that matches the second splicing groove 181. The second splicing block 182 of one braided base unit 14 is inserted into the second splicing groove 181 of the other braided base unit 14 to complete the splicing of the braided base 12. The bottom of the arc-shaped bottom ring 15 and the inner side of the bottom of the base body 18 are rounded to reduce the friction between the base and the yarn.

[0028] like Figure 6 As shown, the rotary braiding machine has a fixed-radius original braided ring 2, which is fixed to an inclined support plate 4 by welding. One end of the inclined support plate 4 has a threaded hole, into which a threaded straight support column 6 is installed. A circular mounting plate 5 is also installed on the straight support column 6, and the circular mounting plate 5 is fixedly connected to the main body of the rotary braiding machine, allowing the original braided ring 2 to be mounted on the machine. The overall height of the original braided ring 2 is adjusted by the threads of the straight support column 6. The mandrel 3 gradually moves upward from below the original braided ring 2. Because the radius of the mandrel 3 changes, while the radius of the original braided ring 2 remains constant, the braiding effect is affected. By installing the replaceable braided ring of this invention at the original braided ring position, the radius of the braided ring can be changed according to the radius of the mandrel 3.

[0029] The method of using the removable and replaceable braided ring of the present invention includes the following steps:

[0030] Step 1: Install the braided base 12. Join the two braided base units 14 together, and push the joined braided base 12 into place from below the original braided ring, so that the base groove 17 abuts against the lower surface of the original braided ring 2, and the base body 18 is located inside the original braided ring 2, thus fixing the position of the braided base 12.

[0031] Step 2: Install the detachable braided ring 11. Since the top of the core mold 3 may be covered by yarn during the braiding process, the detachable braided ring 11 cannot be pushed in from above the core mold 3. Therefore, the two braided ring units 13 are placed on both sides of the core mold 3 for splicing, and the connecting plate 16 is made to abut against the upper surface of the original braided ring 2. The arc-shaped bottom ring 15 is located inside the original braided ring 2 and the base body 18.

[0032] Step 3: Assemble the removable braided ring module 1. Align the screw holes of the removable braided ring 11 and the braiding base 12. Install the screw into the screw hole to fix the removable braided ring 11 and the braiding base 12. Secure both ends of the screw 19 with bolts. The bolt located on one side of the braiding base 12 is installed in the bolt countersunk hole 183 to prevent the bolt from tangling with the yarn. The radius of the arc-shaped base ring 15 is the actual working radius of the removable braided ring module 1 during the braiding process.

[0033] Step 4: Replace the removable braided ring module 1; release the removable braided ring 11 and the braided base 12 from the fixation, then disassemble the removable braided ring 11 and remove it from both sides of the core mold, and replace it with a removable braided ring 11 with a different radius of arc-shaped bottom ring 15.

[0034] This invention installs a removable braided ring module at the original braided ring location. By replacing the arc-shaped base ring with one of different radii, the actual working radius of the braided ring is changed, allowing the braided ring radius to be adjusted according to the prefabricated body size. This results in more uniform weaving and ensures higher weaving quality. Furthermore, the removable braided ring module has a spliced ​​structure, joined on both sides of the core mold, allowing for smooth replacement of the braided ring regardless of its already woven shape. All contact points between the removable braided ring module and the yarn are designed with rounded corners to reduce friction and facilitate smooth weaving. Countersunk bolt holes are also included to prevent the bolts from tangling with the yarn and affecting the weaving process.
