There are various types of rope braiding devices, including hand-operated braiding devices, fixed braiding devices and double-head combined replaceable head braiding devices.

[0003] The utility model discloses a novel braiding device in the authorized publication "CN202865542U", which comprises a shell, a rotating handle mounted on the shell and a driving gear mounted inside the shell.

A crochet needle is coaxially mounted on the side wall of the rotating drum, and four crochet needles are uniformly distributed on the outer side of the rotating drum. The bottom of the crochet needle is connected with a sliding block, which is located in the annular sliding groove on the lower side wall of the shell, so that the crochet needle can perform up-down circular motion while rotating. Thus, the crochet needle can quickly hook the rope and perform braiding.

[0004] The existing hand-operated braiding device is provided with multiple crochet needles for braiding rope, but the latch on the crochet needle is difficult to maintain a horizontal state when closing or opening the crochet needle, which causes the rope to be easily hung by the latch during braiding, affecting the smooth disengagement of the rope, and even causing the rope to be stuck in severe cases, thereby reducing the braiding efficiency.

[0075] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be interpreted as limiting the scope of protection of the present utility model.

[0076] It should be noted that similar reference numbers represent similar items in the following drawings, so once an item is defined in one drawing, it will not be further defined and explained in subsequent drawings.

[0077] The knitter 100 with the crochet hook instant switching mechanism is an innovative tool designed to improve knitting efficiency and reduce operational complexity. It consists of a crank handle assembly 103, at least one replaceable crochet hook instant switching mechanism 101, and a clippable base assembly 102. The crank handle assembly 103 includes a handle 10 and a first gear 11 mounted at the inner end of the handle for driving the knitter.

[0078] The clippable base assembly 102 is used to fix the knitter 100 at the target position F, while the crochet hook instant switching mechanism 101 is installed on the base assembly, including a center column 20 and a second gear 21 connected to the bottom end of the center column, the two gears are meshed with each other to transmit power.

[0079] The crochet hook instant switching mechanism 101 is the core of the knitter, which includes a center column 20 and a plurality of vertically distributed crochet hooks 30 that can move up and down along the column. These crochet hooks 30 consist of a needle body 31 and a rotatable needle latch 32, the needle body has a hook portion 311 at the top end and a needle foot 312 at the bottom end, while the needle latch 32 is connected to the lower side of the hook portion 311, allowing the crochet hook to open and close during the knitting process. This technical means ensures that the latch remains in the appropriate position when the crochet hook is closed or opened, reducing the contact between the rope and the latch, avoiding the problems of catching and sticking the rope.

[0080] Through the crochet hook structure of the utility model, the knitter 100 can provide efficient knitting capability while ensuring smooth and efficient knitting process.

[0081] Specifically, at least three crochet needles 30 are annularly spaced on the central column 20, which are vertically distributed on the outer wall of the central column 20 and can move up and down along the length direction of the central column 20 to realize precise knitting action. Figures 6 to 9 As shown, there are three, four or five crochet needles annularly distributed on the central column 20. Users can choose the appropriate number of crochet needles for knitting according to needs. The flexible configuration of this instant switching mechanism with different number of crochet needles provides users with multiple choices, enabling them to choose the appropriate number of crochet needles according to specific knitting projects and the thickness of the rope.

[0082] The instant switching mechanism of the crochet needle in the utility model can quickly respond to changes in the knitting process, and can maintain high efficiency in both tight knitting and knitting techniques requiring a larger activity space. The vertical movement of the crochet needle 32 is precisely controlled by the inclined annular limiting groove 313 on the central column 20, ensuring the stability and accuracy of the crochet needle during knitting.

[0083] More specifically, the crochet needle 30 includes a needle body 31 and a needle bolt 32 to realize precise knitting action. The needle body 31 has a hook portion 311 at the top end and a needle foot 312 at the bottom end, which work together to enable the crochet needle to firmly grasp and guide the rope. The needle bolt 32 is rotatably connected to the lower side of the hook portion 311, which allows the crochet needle to be flexibly opened and closed during knitting to adapt to different knitting needs.

[0084] The central column 20 is provided with a cylinder 40, and inclined annular limiting grooves 313 are specially provided on the cylinder 40. These limiting grooves are distributed along the movement trajectory of the needle foot 312, ensuring that the crochet needle maintains an accurate trajectory when moving up and down. The needle foot 312 is transversely inserted into the inclined annular limiting groove 313, which limits its upward and downward movement, ensuring the stability and accuracy of the crochet needle during knitting.

[0085] It should be noted that the inclined annular limiting groove 313 is a through groove for the needle foot 312 on the outer wall of the central column to pass through, and the inclined annular limiting groove 313 is annularly distributed along the circumferential wall of the cylinder, and the inclined annular groove 313 is inclined to form a height difference between the first end c1 and the second end c2.

[0086] In the first state, after the needle bolt 32 is fully rotated downward, the needle bolt 32 is vertically distributed to keep consistent with the vertical movement trajectory of the crochet needle 30 along the central column 20, and the bottom end of the needle bolt 32 does not protrude beyond the first outer edge s1 of the needle body 31 in the horizontal direction. This technical means ensures that the crochet needle can smoothly guide the rope in the open state, avoiding rope hooking or rope jamming, and at the same time preparing for the next action in the knitting process.

[0087] In the second state, after the needle latch 32 is fully rotated upward, the hook portion 311 is closed with the needle latch 32, and the first arc of the hook portion 311 transitions continuously with the second arc of the needle latch 32 along s2 and s3. This technical means makes the unthreading process smoother, reduces the friction and jamming of the string during weaving, and improves the efficiency of weaving and the quality of the finished product.

[0088] The clippable base assembly 102 is a key part of the loom 100, which ensures that the loom can be firmly fixed on the workbench or other work surface. This assembly is composed of a base 50 and a clamping piece 60, where the base 50 is provided with an upwardly protruding connecting column with a threaded hole in the middle for cooperation with a threaded rod 62 to achieve stable installation and adjustment of the clamping piece 60. The clamping piece 60 includes a clamping disc 61 and a threaded rod 62, and the clamping disc 61 is connected with the base 50 through the threaded rod 62. The clamping area f between them allows the loom to remain stable when fixed and provides enough space to accommodate different sizes of work surfaces.

[0089] Preferably, the connecting column of the base 50 not only enhances the structural stability, but also increases the aesthetics of the base. This technical means makes the clamping piece 60 easy to install and adjust, providing great convenience for users. Users can adjust the height and angle of the loom as needed to adapt to different working conditions and personal preferences, achieving the best weaving effect.

[0090] In summary, the technical means of the clippable base assembly 102 considers stability, compatibility and user convenience, enabling the loom 100 to work stably in various environments while providing users with flexible adjustment options to adapt to different weaving needs and personal preferences. This carefully designed structure not only improves the practicality of the loom, but also enhances its durability and reliability, making it an ideal choice for weaving enthusiasts and professionals.

[0091] Further, the cylinder 40 includes an upper cylinder 41 and a lower cylinder 42, and a slanted annular limiting groove 313 is formed between the two cylinders; the slanted annular limiting groove 313 includes an upper limiting slope r1 and a lower limiting slope r2; these two slopes precisely control the up-and-down movement of the needle foot 312, ensuring that the crochet needle moves accurately along the predetermined trajectory during weaving.

[0092] During the operation of the loom, the needle foot 312 is located between the upper limiting slope r1 and the lower limiting slope r2. During the upward movement of the crochet needle, the lower limiting slope r2 lifts the needle foot 312 upward, while during the downward movement, the upper limiting slope r1 pushes the needle foot 312 downward. This technical means enables the crochet needle 30 to smoothly perform the up-and-down cyclic motion during weaving, thereby ensuring the continuity and uniformity of the weaving.

[0093] In addition, the upper end of the lower cylinder 42 extends radially outward to form an inclined surface m, and the upper surface of the inclined surface m is connected to the lower limit inclined surface r2 to form a smooth transition area, further ensuring the smoothness of the hook needle movement. Moreover, the existence of the inclined surface m takes into account the reduction of friction and wear, prolonging the service life of the knitting machine, while also making the hook needle more stable during rapid knitting, reducing knitting errors caused by hook needle shaking or displacement. The inclined annular limiting groove 313 and the inclined surface m are carefully designed to ensure that the knitting machine 100 can maintain high-quality standards while achieving high efficiency.

[0094] In summary, the unique inclined annular limiting groove 313 and the inclined surface m of the cylinder body 40 provide precise motion control and smooth motion path for the hook needle.

[0095] Preferably, the upper cylinder 41 is provided with a thread inlet cylinder 43, and the opening of the thread inlet cylinder 43 is in the shape of a trumpet to facilitate the entry of the rope into the area. The opening side of the thread inlet cylinder 43 is provided with a notch k, which further guides the rope and ensures that the rope can accurately enter the knitting area, while providing an additional tension control point during knitting.

[0096] Preferably, the thread inlet cylinder sidewall below the notch k is provided with a guide hole y, which guides the rope to enter the thread inlet cylinder 43 along a predetermined trajectory, ensuring the stability of the rope and reducing movement during knitting. A fixed plug p is provided at the guide hole y. The function of the fixed plug p is to firmly fix the rope at the guide hole y to prevent the rope from shifting during knitting. At the same time, by fixing the end of the rope with external force, the rope can be effectively tightened to ensure uniform tension during knitting, which is crucial for making high-quality knitted products.

[0097] Preferably, the other end of the rope is clamped with a counterweight clamp 70, which clamps the rope that passes out from the bottom of the clamping disc 61. This ensures that the rope is tight during knitting, and also helps to maintain the consistency of the knitting tension.

[0098] It should be noted that the weight of the counterweight clamp 70 is carefully designed to be between 90 grams and 150 grams. This weight is based on multiple experiments and tests we have conducted to find an optimal counterweight to ensure that the counterweight clamp works perfectly with the knitting machine 100. Through this precise weight configuration, we ensure the stability and smoothness of the knitting process, so that the rope tension is maintained just right, thereby improving the efficiency of knitting and the quality of the finished product.

[0099] Further, the center column 20 is provided with vertical distribution of protrusions g, between which the adjacent two protrusions g form a moving groove g1 for the needle 30 to move up and down. The cooperation of the protrusions g and the moving groove g1 ensures that the needle 30 can move accurately along the predetermined trajectory during knitting, thereby ensuring the uniformity and consistency of knitting. Moreover, the stable movement path reduces the shaking and deviation of the needle at high-speed knitting or complex knitting mode.

[0100] Preferably, an outer shell b is sleeved between the thread inlet cylinder 43 and the base 50. On the one hand, the outer shell b provides physical protection for the internal components between the thread inlet cylinder 43 and the base 50. On the other hand, the outer shell b helps to enhance the structural stability of the entire knitting machine by fixing and supporting the thread inlet cylinder and the base, thereby reducing vibration during use.

[0101] The knitting method of the knitting machine 100 with the needle instant switching mechanism includes the following steps:

[0102] (1) First, evaluate the specific task of the knitting project, obtain the required number and type of needles; select a most suitable needle instant switching mechanism 101 and a clippable base assembly 102 to assemble;

[0103] (2) Then, fix the knitting machine on the target position by the clippable base assembly 102 to provide a stable operation platform for knitting.

[0104] (3) In the preparation work, the rope is guided through the guide hole y on the side of the thread inlet cylinder of the cylinder body 40 and fixed with the fixing plug p to maintain the stability of the rope during knitting. Then the rope is sequentially threaded through the middle through hole of the center column 20 and the through hole 62 at the bottom of the clamping disc 61 of the clippable base assembly 102, and finally the first end of the rope is clamped with the counterweight clamp 70 to provide the necessary tension and prepare to start knitting.

[0105] (4) At the beginning of the knitting process, confirm that all the needle plungers 32 of the needles 30 are in the open state, the rope enters the hook of the first needle 3a in the rising state, and at the same time, rotate the handle 10 of the crank handle assembly 103 to drive the first needle 3a to rotate and move downward;
