[0030] As a miniature knitting tool that combines fun, hands-on experience, and creativity, knitting machines are popular among children and craft enthusiasts for their compactness, portability, and ease of use. Their core working principle is to use a hand crank to drive a ring-shaped knitting mechanism, causing the hooks to regularly rise and fall at fixed positions, thereby interweaving and weaving the threads. However, traditional knitting machines have a fixed knitting mechanism, meaning a fixed number of hooks. This means they can only produce fabrics of specific specifications and styles, making it difficult to meet users' increasingly diverse knitting needs.

[0031] See also Figure 1 The embodiment of the present application proposes a braiding machine 1 to solve the above technical problems. The braiding machine 1 includes a housing 10, two types of braiding mechanisms 20 and a driving mechanism 30.

[0032] See also Figure 2The housing 10 serves as the supporting structure of the braiding machine 1 and has a receiving groove 110 with an upper opening. The receiving groove 110 can be arranged in a ring shape to adapt to the rotation of the braiding mechanism 20. The housing 10 may include a base 120 and a supporting foot 130. The base 120 is provided with the receiving groove 110. The supporting foot 130 is detachably mounted on the bottom of the base 120 to support the height of the base 120 for user convenience. The connection method between the supporting foot 130 and the base 120 includes but is not limited to threaded connection, snap connection, plug-in connection, screw connection and other connection methods.

[0033] See also Figures 3 and 4 The knitting mechanism 20 includes a hook cylinder 210, a plurality of hooks 220, a bottom plate 240, and a hook drive unit 250. The hook cylinder 210 is rotatably mounted in the receiving groove 110. The hook cylinder 210 is provided with a plurality of mounting grooves 212 spaced apart along the circumference and extending along the axial direction. One hook 220 is inserted into one mounting groove 212, and the hook 220 can be raised and lowered in the mounting groove 212. The bottom plate 240 is located at the lower part of the hook cylinder 210 and is detachably connected to the housing 10, so that the knitting mechanism 20 is detachably fixed in the receiving groove 110. The hook drive unit 250 is provided on the bottom plate 240 and contacts the bottom of the hook 220. The base plate 240 and the hook cylinder 210 are relatively fixed in the axial direction. In the circumferential direction, the hook cylinder 210 can rotate relative to the base plate 240. Therefore, during the rotation of the hook cylinder 210, the hook drive unit 250 will sequentially contact different hooks 220, thereby driving the hooks 220 to periodically rise and fall during the rotation of the hook cylinder 210, achieving regular rising and falling movement of the hooks 220 at a fixed position. The outer side of the hook cylinder 210 is provided with a gear unit 211, which surrounds the hook cylinder 210.

[0034] See also Figure 4 The hook drive unit 250 can be a smoothly rounded raised structure, and this raised structure is provided at the bottom of the hook cylinder 210 and is used to contact the bottom of the hook 220. During the rotation of the hook cylinder 210, the raised structure is used to drive the hook 220 to periodically rise and fall. The corners of the raised structure are smoothly rounded. In this way, when the hook cylinder 210 rotates, it drives the corresponding hook 220 to rise and fall smoothly along the arc structure, completing the lifting operation. This reduces the impact and jamming of the hook 220 during the lifting process, making the movement of the hook 220 more stable.

[0035] See also Figure 4In order to improve the stability of the crochet hook 220 in lifting and lowering, a guide rail is provided on the base plate 240. The bottom of the crochet hook 220 contacts the guide rail, and the raised structure is provided on the guide rail. The setting of the guide rail reduces the contact area between the crochet hook 220 and the base plate 240, thereby reducing the static friction, so that the crochet hook 220 can move up and down more smoothly along the raised structure during the movement, ensuring the stability of the movement of the crochet hook 220.

[0036] Two guide rails are coaxially spaced apart, including a first guide rail 241 and a second guide rail 242, which are arranged radially outward from the center. The hook 220 is generally L-shaped, with a hook portion at the top and a root portion extending in the radial direction at the bottom. The root portion abuts against the first guide rail 241 and the second guide rail 242 to improve the stability of the hook 220 during rotation. The thickness of the protrusion structure can be set relatively thin. The protrusion structure can be selectively provided on the first guide rail 241 or the second guide rail 242. Of course, the protrusion structure can also be provided on both the first guide rail 241 and the second guide rail 242.

[0037] Optionally, in other embodiments, the bottom plate 240 may not be provided, and the above-mentioned protruding structure and guide rail may be directly provided on the bottom wall of the accommodating groove 110 .

[0038] Please refer to Figure 4 and Figure 5 In some embodiments, the knitting mechanism 20 further includes an inner cylinder 270, the lower end of which is connected to the base plate 240, and an annular retaining structure 271 is provided on the outer wall surface of the upper end of the inner cylinder 270. The hook cylinder 210 is sleeved on the outside of the inner cylinder 270, and the annular retaining structure 271 is used to abut against the annular retaining protrusion 214 on the inner wall of the hook cylinder 210, thereby preventing the hook cylinder 210 from separating from the base plate 240, and further preventing the hook cylinder 210 from separating from the housing 10 during operation. In addition, the inner cylinder 270 can also function as a shaft, and the hook cylinder 210 can rotate around the inner cylinder 270 during rotation, thereby improving the rotation stability of the hook cylinder 210. During installation, the hook cylinder 210 and the hook needle 220 are first placed on the base plate 240, and the inner cylinder 270 is inserted into the hook cylinder 210. The inner cylinder 270 and the base plate 240 are then fixed together. Under the combined action of the base plate 240 and the annular retaining structure 271, the hook cylinder 210 is relatively fixed to the base plate 240 and the inner cylinder 270 in the axial direction, and rotates circumferentially around the inner cylinder 270. The inner cylinder 270 and the base plate 240 can be relatively fixed by screw connection, snap connection, plug connection, etc.

[0039] See also Figure 5The driving mechanism 30 is arranged on the shell 10, and includes a driving source and a driving member. The driving source can be a hand crank 32, or a driving motor. The driving source is connected to the driving member in a transmission manner to drive the driving member to rotate. Exemplarily, the driving source of the present application is a hand crank 32, which is arranged on one side of the shell 10 for user operation; the driving part of the driving member at least partially extends into the accommodating groove 110. When the user drives the hand crank 32 to rotate, it can drive the driving gear 31 to rotate around the axis, so that the driving member drives the hook cylinder 210 to rotate. During the rotation of the hook cylinder 210, the hook 220 will be driven to rotate together. Since the hook drive part 250 is relatively fixed, the hook 220 will contact the hook drive part 250 in turn during the rotation process. When contacting the hook drive part 250, it will first rise and then fall under the action of the hook drive part 250 to achieve lifting. Among them, the driving member may include a driving gear 31, the axial direction of the driving gear 31 extends along the radial direction of the crochet needle cylinder 210, that is, the axial direction of the driving gear 31 is arranged perpendicular to the axial direction of the crochet needle cylinder 210, and the outer periphery of the driving gear 31 is provided with an engaging tooth portion 311. In the process of the driving gear 31 rotating around the axis, the engaging tooth portion 311 engages with the gear portion 211, thereby driving the driving gear 31 to rotate, and at the same time driving the crochet needle cylinder 210 to rotate.

[0040] See also Figure 3 、 Figure 6 as well as Figure 9 , the knitting mechanism 20 includes at least two specifications, and the number of crochet needles 220 of the knitting mechanisms 20 of different specifications is different; or, the number of crochet needles 220 of the knitting mechanisms 20 of different specifications is the same, and the spacing between the crochet needles 220 is different, so that the outer diameters of the crochet needle cylinders 210 of the knitting mechanisms 20 of different specifications may be different. Therefore, when the knitting mechanisms 20 of different specifications are installed in the accommodating groove 110, there will be two situations. When the outer diameter of the crochet needle cylinder 210 is the first specification adapted to the driving mechanism 30, the driving gear 31 can be directly engaged with the gear part 211 of the crochet needle cylinder 210 to drive the crochet needle cylinder 210 to rotate. However, when the outer diameter of the crochet needle cylinder 210 is the second specification smaller than the first specification, since the position of the driving gear 31 is relatively fixed, it is difficult to directly engage with the crochet needle cylinder 210, Based on this, the braiding mechanism 20 of the second specification further includes a transmission mechanism 230, see Figure 6The transmission mechanism 230 includes a transmission gear 231, the axis of which is perpendicular to the axis of the hook cylinder 210. One end of the transmission gear 231 is meshed with the gear portion 211 of the hook cylinder 210, and the other end is tightly fitted with the drive gear 31. In this way, the rotational power of the drive gear 31 can be transmitted to the hook cylinder 210 through the transmission gear 231, driving it to rotate, compensating for the insufficient meshing radius of the small-sized hook cylinder 210, and maintaining a stable output of the rotational torque. Furthermore, the axis of the transmission gear 231 is coaxially arranged with the axis of the drive gear 31, which can ensure the high efficiency and stability of power transmission, reduce energy loss, and enable the rotational power of the drive gear 31 to be more smoothly transmitted to the hook cylinder 210 through the transmission gear 231, thereby improving the working efficiency of the knitting machine 1.

[0041] In the present application, users can flexibly choose to install weaving mechanisms 20 of different specifications according to different weaving needs, thereby weaving fabrics of different styles and sizes. Moreover, since the weaving mechanism 20 of the present application is detachably connected to the housing 10, while adapting to different weaving mechanisms 20, it can also be replaced after the weaving mechanism 20 is damaged.

[0042] Optionally, the number of hooks 220 is proportional to the outer diameter of the hook cylinder 210. Figure 3 、 Figure 6 as well as Figure 9 The weaving mechanism 20 of the present application may include a first weaving mechanism 20a, a second weaving mechanism 20b and a third weaving mechanism 20c, wherein the first weaving mechanism 20a is of the first specification, and the number of crochet needles 220 of the first weaving mechanism 20a is not less than 45 and not more than 50; the second weaving mechanism 20b and the third weaving mechanism 20c are both of the second specification, and the outer diameter of the crochet needle cylinder 210 of the second weaving mechanism 20b is greater than the outer diameter of the crochet needle cylinder 210 of the third weaving mechanism 20c, the number of crochet needles 220 of the second weaving mechanism 20b is not less than 38 and not more than 42, and the number of crochet needles 220 of the third weaving mechanism 20c is not less than 20 and not more than 24.

[0043] For example, the first knitting mechanism 20a has 48 crochet needles 220, the second knitting mechanism 20b has 40 crochet needles 220, and the third knitting mechanism 20c has 22 crochet needles 220. The third knitting mechanism 20c is suitable for knitting small-volume fabrics such as gloves, socks, and scarves. The knitting area of ​​the second knitting mechanism 20b is larger than that of the third knitting mechanism 20c. In addition to being able to knit products that the third knitting mechanism 20c can knit, it can also knit fabrics such as children's hats and pillows. The knitting area of ​​the first knitting mechanism 20a is larger than that of the second knitting mechanism 20b. In addition to the above fabrics, it can also knit fabrics such as adult hats and sweaters. Users can replace different knitting mechanisms 20 according to their needs to meet diverse knitting needs.

[0044] In order to improve the stability of the cooperation between the braiding mechanism 20 and the driving mechanism 30 of the second specification, please refer to Figure 6 as well as Figure 9 The transmission mechanism 230 of the embodiment of the present application also includes a mounting seat 232. The middle part of the mounting seat 232 is provided with a mounting cavity 232A with an upper opening. The hook cylinder 210 is installed in the mounting cavity 232A and is fixed relative to the mounting seat 232 in the axial direction to prevent the hook cylinder 210 from being separated from the mounting seat 232 during rotation. The hook cylinder 210 is rotatable relative to the mounting seat 232 in the circumferential direction to meet the requirements of the normal operation of the hook cylinder 210. The mounting seat 232 is detachably fixed in the accommodating groove 110. By fixing and disassembling the mounting seat 232 and the shell 10, the knitting mechanism 20 of the second specification can be installed on the shell 10. Among them, the mounting seat 232 is provided with a mounting hole 232a extending in the radial direction, and the transmission gear 231 is rotatably mounted in the mounting hole 232a.

[0045] See also Figures 7 to 10 The mounting seat 232 includes a seat body 2321 and a connecting member 2322. The seat body 2321 is detachably fixed in the accommodating groove 110. The seat body 2321 can be provided in a cylindrical structure, which is convenient for forming a mounting cavity 232A for mounting the hook needle cylinder 210 and for being installed in the accommodating groove 110. The seat body 2321 is provided with a limiting hole 232d, wherein the limiting hole 232d connects the outer space and the inner space (i.e., the mounting cavity 232A) of the seat body 2321. The hole wall of the limiting hole 232d is formed with a first notch 232e. The connecting member 2322 is detachably provided in the limiting hole 232d and is provided with a second notch 23221. The second notch 23221 and the first notch 232e enclose a mounting hole 232a. Furthermore, the first notch 232e forms the bottom wall of the lower half of the mounting hole 232a, and the second notch 23221 forms the top wall of the upper half of the mounting hole 232a.

[0046] Please refer to Figure 14 a. The transmission gear 231 includes a rotating part 2311 and a first transmission part 2312 and a second transmission part 2313 located at opposite ends of the rotating part 2311. When the second transmission part 2313 is installed, the rotating part 2311 is placed on the first notch 232e. At this time, the first transmission part 2312 is located at one end close to the outer space of the seat body 2321, and is used to cooperate with the driving gear 31. The second transmission part 2313 is located at one end close to the inner space of the seat body 2321, and is meshed and connected with the gear part 211 of the second specification crochet needle cylinder 210. Then the connecting piece 2322 is connected to the seat body 2321, and the transmission gear 231 can be installed and fixed in the mounting hole 232a.

[0047] Please continue reading Figure 14 b. In some embodiments, the rotating portion 2311 includes a rotating shaft 23111 and a first limiting portion 23112 and a second limiting portion 23113 connected to the rotating shaft 23111 and spaced apart in the axial direction of the rotating shaft 23111. The rotating shaft 23111 is rotatably mounted on the mounting hole 232a. The first limiting portion 23112 and the second limiting portion 23113 are located at opposite ends of the seat body 2321 and / or the connecting member 2322, and are limitedly matched with the seat body 2321 and / or the connecting member 2322 to relatively fix the rotating shaft 23111 and the mounting hole 232a in the axial direction of the rotating shaft 23111, thereby improving the stability of the rotation.

[0048] See also Figure 9 and Figure 10 To improve the structural strength of the mounting base 232 while reducing its weight, the mounting base 232 includes an annular outer shell 23211, an annular inner shell 23212, and an annular top plate 23213. The annular outer shell 23211 and the annular inner shell 23212 are coaxially spaced apart to form an annular gap. The annular top plate 23213 is disposed on top of the annular outer shell 23211 and the annular inner shell 23212 to relatively fix the annular outer shell 23211 and the annular inner shell 23212. This saves material, reduces weight, and reduces costs. The hook cylinder 210 is rotatably mounted on the inner side of the annular inner shell 23212.

[0049] See also Figure 10 and Figure 11The annular outer shell 23211 is provided with an arcuate mounting portion extending in the radial direction. The arcuate mounting portion defines at least a first notch 232e. Furthermore, the length of the connecting member 2322 in the radial direction is adapted to the length of the arcuate mounting portion. This configuration increases the contact area between the transmission gear 231 and the wall of the mounting hole 232a, thereby improving the stability of the transmission gear 231 during torque transmission and preventing the transmission gear 231 from tilting or becoming unbalanced. Correspondingly, the annular inner shell 23212 is provided with a relief opening 23216 communicating with the mounting hole 232a. Once installed in the mounting hole 232a, the transmission gear 231 can mesh with the gear portion 211 of the hook cylinder 210 through the relief opening 23216.

[0050] Please continue reading Figure 10 and Figure 11 Furthermore, the arc-shaped mounting portion includes an arc-shaped portion and a fixing portion located on opposite sides of the arc-shaped portion in the circumferential direction, the arc-shaped portion forms a first notch 232e, and the connecting member 2322 includes a corresponding arc portion and a mounting portion connected to opposite sides of the arc portion, the arc portion forms a second notch 23221, and the mounting portion and the fixing portion are fixedly connected to each other, so that the first notch 232e and the second notch 23221 are enclosed to form the mounting hole 232a. Optionally, the mounting portion and the fixing portion can be connected together using threaded fasteners, snap-fit ​​connections, plug-in connections, etc. Exemplarily, both the mounting portion and the fixing portion are provided with threaded holes, and screws are sequentially inserted into the threaded holes of the mounting portion and the threaded holes of the fixing portion, thereby fixing the connecting member 2322 to the seat body 2321.

[0051] In some embodiments, the bottom plate 240 is connected to the bottom of the annular outer shell 23211 and the annular inner shell 23212 , thereby improving the overall structural strength and stability of the mounting base 232 .

[0052] In some embodiments, the second specification hook cylinder 210 may also have different outer diameters, such as Figure 13 and Figure 17 As shown, the outer diameters of the hook cylinder 210 of the second weaving mechanism 20b and the hook cylinder 210 of the third weaving mechanism 20c are not the same, and the length of the transmission gear 231 is inversely proportional to the outer diameter of the hook cylinder 210. When the outer diameter of the hook cylinder 210 is smaller, the length of the transmission gear 231 is larger. Since the annular shell 23211 is a plate extending in the axial direction and the arc-shaped mounting portion is a component extending in the radial direction, under the limitations of injection molding, hot pressing and other processes, the size of the arc-shaped mounting portion in the radial direction will not be large. Therefore, when the length of the transmission gear 231 is longer, the transmission gear 231 may rotate unbalanced.

[0053] Based on this, the present application sets the mounting hole 232a as a segmented support structure, see Figure 12 and Figure 13 The mounting hole 232a includes at least two radially connected hole segments, namely a first hole segment 232b and a second hole segment 232c. The connecting member 2322 includes a first connecting member 23222 and a second connecting member 23223. The arcuate mounting portion provided on the annular housing 23211 is defined as a first arcuate mounting portion 23215. The bottom plate 240 is further provided with a second arcuate mounting portion 243 protruding toward the annular top plate 23213. The first arcuate mounting portion 23215 cooperates with the first connecting member 23222 to define the first hole segment 232b, and the second arcuate mounting portion 243 cooperates with the second connecting member 23223 to define the second hole segment 232c. This improves the rotational stability of the transmission gear 231. It is understandable that when the length of the transmission gear 231 is relatively short, only one arc-shaped mounting portion and one connecting member 2322 may be provided. When the length of the transmission gear 231 is relatively long, two or more arc-shaped mounting portions and connecting members 2322 matching the number of arc-shaped mounting portions may be provided. The base plate 240 may be provided with one or more arc-shaped mounting portions as required, and the length of the arc-shaped mounting portion may also be provided as required.

[0054] It is understandable that the number of the first limiting portions 23112 and the second limiting portions 23113 spaced apart on the rotating shaft 23111 can be adapted to the number of the hole segments of the mounting hole 232a, and corresponding first limiting portions 23112 and second limiting portions 23113 can be provided on each hole segment. Figure 14 b. Exemplarily, the first hole segment 232b and the second hole segment 232c are each correspondingly provided with a set of first limiting portions 23112 and second limiting portions 23113.

[0055] Optionally, the arc-shaped mounting portion may be provided only on the bottom plate 240, and not on the annular outer shell 23211. In other embodiments, the arc-shaped mounting portion may also be provided on the annular inner shell 23212. The specific form of the arc-shaped mounting portion may refer to the form of the arc-shaped mounting portion provided on the annular outer shell 23211. Here, the present application does not limit the specific forming method of the mounting hole 232a.

[0056] In some embodiments, the annular inner shell 23212 and the annular top plate 23213 are integrally formed components, and the annular outer shell 23211 and the bottom plate 240 are integrally formed components. In this way, the assembly work of parts can be reduced, production efficiency can be improved, and the integrity of the structure can be improved. In summary, the mounting seat 232 of the present application can include two shell parts, the first shell part has the bottom plate 240 and the annular outer shell 23211, forming a cover form with an upper opening, and the second shell part has the annular top plate 23213 and the annular inner shell 23212, forming a cover form with an inner wall that is open at the bottom and outside. The first shell part and the second shell part can be connected and fixed in the form of threaded fasteners, snap-on connections, etc. After the two shells are installed and fixed, a ring-shaped mounting seat 232 is formed. The middle part of the mounting seat 232 has a mounting cavity 232A, and the crochet needle cylinder 210 can be installed in the mounting cavity 232A. When the mounting seat 232 is installed in the accommodating groove 110, the crochet needle cylinder 210, the crochet needle 220 and other structures are also fixed in the accommodating groove 110 to form a complete weaving work unit.

[0057] Specifically, during installation, the transmission gear 231 is first placed on the arc-shaped mounting portion. At this time, the first shell and the second shell have not been fixed yet, and the top of the first shell is open to facilitate the installation of the transmission gear 231. Then, the connecting piece 2322 is fixed to the first shell 10, thereby fixing the transmission gear 231 in the mounting hole 232a. Then, the second shell is covered on top of the first shell and fixedly connected to the first shell. At this time, the transmission gear 231 can be installed in the mounting seat 232.

[0058] In other embodiments, the mounting seat 232 may be in the form of a fixed frame, that is, the mounting seat 232 may not be configured in the form of a cylinder, as long as it can install the transmission gear 231 and allow the transmission gear 231 to rotate without interfering with the rotation of the crochet cylinder 210.

[0059] See also Figure 5 、 Figure 13 as well as Figure 16 The driving member includes a coaxially connected driving gear 31 and a transmission rod 35 , the driving gear 31 at least partially extends into the accommodating groove 110 , and the end of the transmission rod 35 away from the driving gear 31 is connected to the hand crank 32 .

[0060] See also Figure 15In some embodiments, the outer periphery of the driving gear 31 is provided with a meshing tooth portion 311, and the inner side is provided with a connecting and fitting portion 312. When the outer diameter of the hook needle cylinder 210 is of the first specification, the meshing tooth portion 311 directly meshes with the gear portion 211; when the outer diameter of the hook needle cylinder 210 is of the second specification, the connecting and fitting portion 312 is tightly matched with the transmission gear 231. Specifically, the tooth shape, tooth pitch and other parameters of the meshing tooth portion 311 match the corresponding parameters of the gear portion 211 of the hook needle cylinder 210, ensuring that the two can be stably and efficiently meshed and transmitted. The connecting and fitting portion 312 can be a protrusion or groove with a specific shape. Among them, the middle part of the driving gear 31 is recessed inward with a groove, and a protrusion with a specific structure is protruded on the side wall or bottom wall of the groove. The protrusion can be multiple or one, and the shape can be square or other regular or irregular shapes. The groove and the protrusion together constitute the connecting and fitting portion 312. By cooperating the protrusions and grooves with the corresponding structures on the transmission gear 231, the two are relatively fixed in the circumferential direction, thereby being able to transmit torque. The present application does not impose any restrictions on the specific structure of the connecting fitting portion 312, as long as the transmission gear 231 and the drive gear 31 can be relatively fixed in the axial direction.

[0061] Please continue reading Figure 15 Furthermore, neither the meshing tooth portion 311 nor the connecting fitting portion 312 exceeds the outer wall surface of the driving gear 31. This avoids interference between the meshing tooth portion 311 and the connecting fitting portion 312. For example, when the meshing tooth portion 311 is engaged with the gear portion 211, the connecting fitting portion 312 does not engage. If the connecting fitting portion 312 exceeds the outer wall surface of the driving gear 31, it is easy to affect the engagement between the meshing tooth portion 311 and the gear portion 211. Similarly, when the connecting fitting portion 312 is engaged with the transmission gear 231, the meshing tooth portion 311 does not work. If the meshing tooth portion 311 exceeds the outer wall surface of the driving gear 31, it is easy to collide or interfere with other components, affecting the normal operation of the driving gear 31 and even causing damage. Therefore, limiting the meshing tooth portion 311 and the connecting fitting portion 312 within the outer wall surface of the driving gear 31 can ensure that the driving gear 31 can operate stably and reliably under various working conditions.

[0062] See also Figure 16In some embodiments, the drive mechanism 30 further includes a locking member 36 and a reset member 37. An installation space 140 communicating with the accommodating groove 110 is provided within the housing 10. The transmission rod 35, the driving gear 31, the locking member 36, and the reset member 37 are all installed within the installation space 140. At least a portion of the end of the driving gear 31 distal from the transmission rod 35 extends into the accommodating groove 110 to mesh with the gear portion 211 or the transmission gear 231. At least a portion of the end of the transmission rod 35 distal from the driving gear 31 extends beyond the outer side of the housing 10 to be in transmission connection with the hand crank 32. The reset member 37 may be in the form of a spring, a tension spring, a compression spring, or the like.

[0063] The locking member 36 is slidable within the housing 10 and has a connecting constraint hole 361 and a release hole 362. The reset member 37 is used to reset the locking member 36. When the transmission rod 35 is located in the constraint hole 361, the transmission rod 35 is fixed in the axial direction. When the transmission rod 35 is located in the release hole 362, the transmission rod 35 can move axially to drive the drive gear 31 out of the receiving groove 110. In this way, when the braiding mechanism 20 needs to be replaced, the drive gear 31 can be driven out of the receiving groove 110 to avoid interference between the drive gear 31 and the braiding mechanism 20.

[0064] The transmission rod 35 is provided with an annular groove 351. The inner diameter of the restraining hole 361 matches the outer diameter of the transmission rod 35 at the annular groove 351, and the inner diameter of the release hole 362 is larger than the outer diameter of the transmission rod 35. Specifically, the transmission rod 35 can be viewed as having a first rod segment and a second rod segment located on opposite sides of the first rod segment. The outer diameter of the first rod segment is smaller than the outer diameter of the second rod segment, thereby forming the aforementioned annular groove 351. When the first rod segment is located within the restraining hole 361, the end surface of the second rod segment abuts against the locking member 36, thereby ensuring that the transmission rod 35 is relatively fixed in the axial direction within the restraining hole 361. The diameter of the release hole 362 is larger than the outer diameters of the first and second rod segments. When the transmission rod 35 is located within the release hole 362, no interference occurs, thereby allowing the transmission rod 35 to move in the axial direction, thereby driving the drive gear 31 to move in the axial direction.

[0065] See also Figure 13 and Figure 16In some embodiments, the driving mechanism 30 further includes a mounting bracket 33, which is installed in the mounting space 140 and fixed relative to the shell 10. The mounting bracket 33 is provided with a slide groove 34, and the locking member 36 can be slidably arranged in the slide groove 34, thereby improving the sliding stability of the locking member 36. Among them, the locking member 36 includes an operating portion 363 and an installation limit portion 364 that are relatively arranged. The reset member 37 can be a spring. The spring is sleeved on the installation limit portion 364, and the opposite ends respectively abut the end surface of the operating portion 363 close to the spring and the bottom wall of the slide groove 34. The surface of the shell 10 is provided with an operating hole 150 connected to the installation space 140. The operating portion 363 of the locking member 36 is exposed in the operating hole 150 away from the end surface of the spring. The user presses the locking member 36 to move the locking member 36. At this time, the constraint hole 361 will move relative to the transmission rod 35, so that the release hole 362 is aligned with the transmission rod 35, thereby unlocking the transmission rod 35. At this time, the transmission rod 35 and the driving gear 31 can be driven to exit the accommodating groove 110 by the hand crank 32. During installation, after the transmission rod 35 and the driving gear 31 are installed in place, the locking piece 36 is loosened so that the restraining hole 361 is sleeved on the position where the annular groove 351 is provided on the transmission rod 35, thereby achieving axial fixation of the transmission rod 35 and the driving gear 31.

[0066] Furthermore, the present application may also include a counting device 70 for counting the number of revolutions of the hook cylinder 210 for the user to read. The counting device 70 includes a connecting gear set and a digital display. The driving gear 31 may include a first gear segment and a second gear segment connected to each other. The outer periphery of the first gear segment is provided with the aforementioned meshing tooth portion 311, and the inner periphery is provided with the aforementioned connecting mating portion 312. The second gear segment is connected to the transmission rod 35 and has a transmission structure provided on the outer periphery. The transmission structure is in transmission connection with the connecting gear set. When the driving gear 31 rotates, the first gear segment drives the hook cylinder 210 to rotate, and the second gear segment drives the connecting gear set to rotate, thereby driving the digital display to count. The connecting gear set includes at least two stages of reduction gears with a reduction ratio of 1:10 to 1:30, so that the digital display increments by 1 for each revolution of the hook cylinder 210. The digital display is a mechanical digital wheel, including multiple coaxially arranged counting discs, each of which is sequentially linked by a one-way ratchet mechanism.

[0067] Please return to Figure 2 and Figure 4To facilitate the replacement and fixing of different braiding mechanisms 20, a fixing groove communicating with the accommodating groove 110 is provided at the bottom of the housing 10. The braiding machine 1 also includes a locking knob 40, which includes a knob portion 41, a shaft portion 42, and a locking portion 43 connected in sequence. The shaft portion 42 is rotatably mounted in the fixing groove, and the knob portion 41 is located outside the housing 10, while the locking portion 43 extends into the accommodating groove 110. The bottom plate 240 is provided with a locking groove 244 that matches the locking portion 43. When the locking knob 40 is rotated to a first angle, the locking portion 43 can be inserted into or removed from the locking groove 244 to fix or release the bottom plate 240. When the locking knob 40 is inserted into the locking groove 244 and rotated to a second angle, the locking portion 43 and the bottom plate 240 are relatively fixed, thereby fixing the braiding mechanism 20 in the accommodating groove 110. The locking knob 40 makes it extremely easy to fix and replace the braiding mechanism 20. The user only needs to rotate the knob portion 41 to insert the locking portion 43 into or out of the locking slot 244 without the need for complicated tools.

[0068] Please refer to Figure 1 、 Figure 6 as well as Figure 12 In order to improve the stability of the yarn routing during the weaving process, the embodiment of the present application also includes a lead frame 50, which is arranged on the inlet side of the hook 220 and can effectively guide and position the yarn before it enters the hook 220. Since the weaving mechanism 20 of the present application has a variety of specifications, in order to further improve the stability of the yarn guidance by the lead frame 50, the present application sets the lead frame 50 in a detachable and fixed form, and the installation position of the lead frame 50 can be flexibly selected. When the hook cylinder 210 is of the first specification, the lead frame 50 is detachably mounted on the top of the housing 10. When the hook cylinder 210 is of the second specification, the lead frame 50 is detachably mounted on the top of the mounting seat 232, that is, the top of the annular top plate 23213. In this way, the lead frame 50 can be installed in different positions according to the specifications of the weaving mechanism 20, so as to be as close to the hook 220 as possible, reduce the swing amplitude of the yarn during the process of entering the hook 220, and ensure that the yarn routing is more stable.

[0069] Both the housing 10 and the mounting seat 232 are provided with a mounting boss (not shown in the figure), and a first magnetic member is provided on the mounting boss. A clamping portion is provided on the top of the lead frame 50, and a mounting groove is provided on the bottom. The clamping portion is used to clamp the yarn, and the mounting boss is nested in the mounting groove. The lead frame 50 is also provided with a second magnetic member, and the first magnetic member and the second magnetic member are magnetically attracted to each other. Among them, at least one of the first magnetic member and the second magnetic member is a magnet, and the other can be a magnet or a material that can be attracted by a magnet. During installation, the user only needs to align the mounting groove at the bottom of the lead frame 50 with the mounting boss on the housing 10 or the annular top plate 23213, and then gently place it. The magnetic attraction will automatically adsorb and fix the lead frame 50, without the need to use complex tools or perform tedious assembly operations, which greatly saves installation time and effort. In addition, the mounting boss and the mounting groove can provide precise positioning for the lead frame 50.

[0070] It is further explained that in the radial direction of the weaving mechanism 20, the lead frame 50 and the crochet drive unit 250 are roughly aligned. When the crochet drive unit 250 drives the crochet 220 to rise and fall, the crochet 220 will hook the yarn and move downward with the yarn, weaving the yarn according to a predetermined weaving pattern and rules.

[0071] Please return to Figure 3 and Figure 4 The knitting mechanism 20 further includes a yarn separating ring 260, which is mounted on the top of the hook cylinder 210. The yarn separating ring 260 is provided with a plurality of yarn separating parts, which are used to guide the yarn to be arranged and directed in an orderly manner along a predetermined path during the descent of the hook 220.

[0072] Furthermore, a plurality of yarn separation parts are also provided on the top of the hook cylinder 210. For the convenience of description and distinction, the yarn separation part provided on the top of the hook cylinder 210 is defined as the first yarn separation part 213, and the yarn separation part provided on the yarn separation ring 260 is defined as the second yarn separation part 262. The first yarn separation part 213 is provided corresponding to the mounting groove 212. Specifically, each first yarn separation part 213 includes a first guide protrusion and a second guide protrusion. Along the circumference of the knitting mechanism 20, a first guide protrusion and a second guide protrusion are respectively provided on both sides of each mounting groove 212, and each set of first guide protrusions and second guide protrusions are symmetrically provided relative to the corresponding mounting groove 212.

[0073] The yarn separating ring 260 includes a ring body 261 and a plurality of second yarn separating parts 262 arranged at intervals on the inner side of the ring body 261. An avoidance groove is formed between the plurality of second yarn separating parts 262. After the yarn separating ring 260 is installed on the top of the crochet tube 210, the first yarn separating part 213 is located in the avoidance groove, and the second yarn separating part 262 is located between two adjacent first yarn separating parts 213, that is, in the circumferential direction of the weaving mechanism 20, the first yarn separating part 213 and the second yarn separating part 262 are staggered.

[0074] In the height direction, the height of the first yarn separating portion 213 is lower than the height of the second yarn separating portion 262. The second yarn separating portion 262 has a second guide surface that extends from the outside toward the center in the radial direction of the knitting machine 1 and is inclined from top to bottom toward the inside of the hook cylinder 210. The first yarn separating portion 213 has a first guide surface that extends from the center toward the outside in the radial direction of the knitting machine 1 and is inclined from top to bottom toward the outside of the hook cylinder 210. In this arrangement, the first yarn separating portion 213 and the second yarn separating portion 262 are staggered in the radial direction.

[0075] During the knitting process, when starting the needle, along the circumferential direction, a crochet hook 220 hooks the yarn and puts it on the first yarn separating part 213. The crochet hook 220 will move the yarn to the position of the first yarn separating part 213 and, under the action of the first guide surface, the yarn will be placed on the first yarn separating part 213. The other crochet hook 220 does not hook the yarn and will move the back of the crochet hook 220 under the guidance of the second guide surface. Then, the yarn is hung on the needles one by one. In the subsequent knitting process, one crochet hook 220 will continue to hook the yarn and the next crochet hook 220 will not hook the yarn. The yarn is interwoven under the action of the first yarn separating part 213 and the second yarn separating part 262, thereby realizing knitting. The knitting principle of the knitting machine 1 has long been disclosed in the relevant art and will not be described in detail in this application.

[0076] It is further explained that in the present application, the first yarn separating portion 213 is arranged on the hook cylinder 210, and the second yarn separating portion 262 is arranged on the yarn separating ring 260, so as to avoid production difficulties during the injection molding and demolding processes. During the injection molding process, the design and manufacture of the mold need to take into account the shape, size and connection relationship of each component. If the first yarn separating portion 213 and the second yarn separating portion 262 are integrated into one component, the structure of this component may become very complicated, making the cavity of the injection mold difficult to process and manufacture, increasing the cost and time of mold manufacturing. At the same time, during the demolding process, it is easy for the friction between the mold and the product to be too large, causing the product to be deformed or damaged. However, the first yarn separating portion 213 and the second yarn separating portion 262 are arranged separately, respectively on the hook cylinder 210 and the yarn separating ring 260, so that the structure of each component can be relatively simple, which is convenient for the design and manufacture of the injection mold, reduces production costs, and improves production efficiency. Of course, in other embodiments, the first yarn separating portion 213 and the second yarn conducting portion are both integrated into the yarn separating ring 260 .

[0077] See also Figure 1 and Figure 17 This embodiment of the present application also includes a yarn tension adjustment device 90, which is snap-connected to the housing 10 and located on one side of the housing 10 to adjust the tension of the yarn. Specifically, the yarn tension adjustment device 90 includes a thread-holding body 91 and a snap-connecting portion 92. The thread-holding body 91 is provided with at least two thread-holding slots 911; the openings of two adjacent thread-holding slots 911 can be located on the same side or on different sides. In this embodiment, there are four thread-holding slots 911. As the yarn is sequentially wound through multiple thread-holding slots 911, the effective yarn path length increases with each additional winding, increasing frictional resistance, thereby achieving incremental tension adjustment. The snap-connecting portion 92 is connected to the end of the thread-holding body 91 facing away from the thread-holding slots 911. To ensure a secure connection between the yarn tension adjustment device 90 and the housing 10 while ensuring quick assembly and disassembly, snap-connecting portions 921 are provided on opposite sides of the snap-connecting portion 92. The housing 10 is provided with matching slots corresponding to the two snap-on structures 921. The hook-shaped snap-on structure 921 can achieve a tight fit with the slots on the housing 10 through its elastic deformation, providing a certain clamping force. The plate-shaped snap-on structure 921 can be inserted into the slots on the housing 10, further enhancing the stability of the connection through its position-limiting effect. This hybrid snap-on structure effectively prevents the yarn tension adjustment device 90 from loosening or falling off during use, ensuring its reliability during operation of the knitting machine.

[0078] It is further explained that in the radial direction of the weaving mechanism 20, the lead frame 50, the crochet drive unit 250 and the yarn tension adjustment device 90 are roughly aligned, and the yarn is sequentially wound around the yarn tension adjustment device 90 and the lead frame 50. Then, in the process of the crochet drive unit 250 driving the crochet 220 to rise and fall, the crochet 220 will hook the yarn coming out of the lead frame 50 and move downward with the yarn, weaving the yarn according to a predetermined weaving pattern and rule.

[0079] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "up", "down", "left", "right", etc. indicate directions or positional relationships, they are based on the directions or positional relationships shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention.
