Description

Technical Field

[0001] The invention relates to the technical field of rope braiding, and in particular to a rope braiding device with a hook instant switching mechanism. Background Art

[0002] A rope braider is a tool used to braid yarn, rope and other materials, which can help people complete various weaving projects more easily. There are many types of rope braiders, including hand-cranked braiders, fixed braiders and double-headed combined braiders with interchangeable heads.

[0003] The utility model patent with the authorization publication number "CN202865542U" discloses a new type of weaving device, including a housing, a rotating handle installed on the housing, and a driving gear installed inside. The rotation of the rotating handle will drive the rotating drum in the housing, and the bottom of the rotating drum is equipped with a rotating gear that meshes with the driving gear. A crochet hook is coaxially installed on the side wall of the rotating drum. There are four crochet hooks and they are evenly distributed on the outside of the rotating drum. A sliding block is connected to the bottom of the crochet hook. The sliding block is located in an annular groove on the lower side wall of the housing, so that the crochet hook can move up and down while rotating. Thereby, the crochet hook can quickly hook the rope and weave.

[0004] The existing hand-cranked rope braiding machine is equipped with multiple hooks for weaving ropes. However, the pin on the hook is difficult to keep in a horizontal state with the hook when closing or opening the hook, so that the rope is easily caught by the pin during the weaving process, making it not smooth when the rope is detached. In severe cases, the rope will be stuck by the pin, making it impossible to carry out rope braiding, and staff need to handle it, which seriously reduces the efficiency of rope braiding.

[0005] In order to solve the problem that the pin of the existing hand-cranked braiding machine is difficult to keep horizontal when the hook is closed or opened, the problem causes the rope to be easily caught by the pin during the braiding process, affecting the smooth detachment of the rope, and even causing the rope to be stuck in severe cases, thereby reducing the efficiency of braiding. To this end, we proposed a new type of braiding machine, which is equipped with a braiding mechanism for quick wire feeding and wire removal. The hook pin of the braiding structure has an optimized swing trajectory and can ensure that the pin can maintain a predetermined position when the hook is closed or opened, reducing the contact between the rope and the pin, avoiding the problem of hooking and jamming the wire, and improving the braiding efficiency.

[0025] A further preferred technical solution of the present invention is: it also includes a fixing plug, which is used to be inserted into the wire opening to fix the rope at the wire opening.

[0026] Another subject: A knitting method of a knitting machine with a crochet instant switching mechanism, comprising the following steps:

[0027] (1) Select a desired hook instant switching mechanism and assemble it with a clampable base assembly;

[0028] (2) fixing the braider at a target position by means of the clampable base assembly;

[0029] (3) First, pass the wire through the wire opening on the side of the wire inlet barrel on the upper side of the barrel body, and fix the wire at the wire opening with a fixing plug; then, pass the wire through the middle through hole of the center column and the bottom through hole of the clamping plate that can clamp the base assembly in sequence, and use a counterweight clamp to clamp the first end of the wire;

[0030] (4) confirming that the needle latches of all crochet hooks are in the open state, the rope thread enters the hook portion of the first crochet hook in the ascending state, and at the same time, the handle of the crank assembly is rotated to drive the first crochet hook to rotate and move downward;

[0035] Compared with the prior art, the advantages of the present invention are: first, the optimized hook pin swing trajectory ensures that the pin can be kept in a given position when the hook is closed or opened, reducing unnecessary contact with the rope. This technical means reduces the risk of the rope being caught by the pin, thereby avoiding the jamming and breaking of the rope and ensuring the continuity of the weaving process. The new braiding device ensures that the rope passes more smoothly and reduces friction and resistance during the weaving process. This not only increases the weaving speed, but also improves the quality of the finished product, because the rope can be woven into the work more evenly.

[0036] In addition, the rope braiding device of the present invention allows the user to replace the hook instant switching mechanism with different numbers of configurations according to specific braiding needs. This flexibility means that the rope braiding device can adapt to various braiding projects, and the user can meet the needs by replacing the hook instant switching mechanism. This technical means significantly improves the applicability and versatility of the rope braiding device.

[0037] In addition, the braider of the present invention can be fixed on the work surface by a clampable base assembly. This feature is crucial to maintaining stability during the weaving process. The braider fixed on the surface reduces movement caused by improper operation or accidental touch, thereby ensuring the continuity and consistency of the weaving action. Since the braider is fixed on the work surface, the user can focus more on weaving skills and technical means instead of worrying about the position or stability of the equipment. This fixing method reduces the labor intensity of constantly adjusting the position of the equipment during the weaving process, making the weaving work more efficient. Moreover, the fixing or releasing action of the clampable base assembly is also easy to operate. The user can easily fix the braider on the work surface or quickly remove it, so as to quickly switch or move the braider in different work scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0057] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0058] The knitting machine 100 with hook instant switching mechanism is an innovative tool, which is designed to improve knitting efficiency and reduce operation complexity. It is composed of a crank assembly 103, at least one replaceable hook instant switching mechanism 101, and a clampable base assembly 102. The crank assembly 103 includes a handle 10 and a first gear 11 installed at the inner end of the handle, which is used to drive the knitting machine.

[0059] The clampable base assembly 102 is used to fix the knitting machine 100 at the target position F, and the hook instant switching mechanism 101 is installed on the base assembly, including a central column 20 and a second gear 21 connected to the bottom end thereof, and the two gears are meshed with each other to transmit power.

[0060] The crochet hook instant switching mechanism 101 is the core of the knitting machine, which includes a central column 20 and a plurality of crochet hooks 30 vertically distributed along the column and movable up and down. These crochet hooks 30 are composed of a needle body 31 and a rotatable needle latch 32. The needle body has a top hook 311 and a bottom needle foot 312, and the needle latch 32 is connected to the lower side of the hook 311, allowing the crochet hook to be opened and closed during the knitting process. This technical means ensures that the latch can maintain an appropriate position when the crochet hook is closed or opened, reduces the contact between the rope and the latch, and avoids the problem of hooking and jamming the thread.

[0061] By means of the invented hook machine structure, the knitting machine 100 can provide efficient knitting capabilities while ensuring smoothness and efficiency during the knitting process.

[0062] Specifically, at least three hooks 30 are distributed in an annular manner on the central column 20. These hooks 30 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 achieve precise knitting action. Figures 6 to 9 As shown, there are three, four, or five crochet hooks distributed in an annular pattern on the central column 20. The user can select the appropriate number of crochet hooks for knitting as needed. The flexible configuration of the instant switching mechanism with different numbers of crochet hooks provides users with multiple options, allowing them to select the appropriate number of crochet hooks according to the specific knitting project and the thickness of the rope.

[0063] The instant hook switching mechanism of the present invention can quickly respond to changes in the knitting process, and can maintain high efficiency in both tight knitting and knitting techniques that require a large space for movement. The vertical movement of the hook 32 is precisely controlled by the oblique annular limit groove 313 on the central column 20, ensuring the stability and accuracy of the hook during the knitting process.

[0064] More specifically, the crochet needle 30 includes a needle body 31 and a needle pin 32 to achieve precise knitting movements. The needle body 31 has a hook portion 311 at the top and a needle foot 312 at the bottom, and these two parts work together to enable the crochet needle to firmly grasp and guide the thread. The needle pin 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 the knitting process to meet different knitting needs.

[0065] The central column 20 is provided with a cylinder 40, on which oblique annular limiting grooves 313 are specially provided. These limiting grooves are distributed along the movement track of the needle foot 312 to ensure that the crochet needle maintains an accurate track when moving up and down. The needle foot 312 is laterally inserted into the oblique annular limiting groove 313, and the limiting groove limits the upper and lower positions of the needle foot 312 to ensure the stability and accuracy of the crochet needle during the knitting process.

[0066] It should be noted that the oblique annular limiting groove 313 is a through groove for the needle base 312 on the outer wall of the center column to pass through. The oblique annular limiting groove 313 is distributed in a ring along the circumferential side wall of the cylinder body, and the oblique annular groove 313 is inclined so that a height difference is formed between its first end and the second end.

[0067] In the first state, Figure 12 to Figure 14 As shown, after the needle pin 32 rotates downward, the needle pin 32 is vertically distributed to keep consistent with the trajectory of the crochet needle 30 moving vertically along the central column 20, and the bottom end of the needle pin 32 does not extend horizontally beyond the first outer edge s1 of the needle body 31. This technical means ensures that the crochet needle can smoothly guide the rope in the open state to avoid the rope hooking or jamming, and at the same time prepares for the next step in the knitting process.

[0068] In the second state, if Fig.15 As shown, after the needle plug 32 rotates upward, the hook portion 311 and the needle plug 32 are closed, and the first arc edge s2 of the hook portion 311 and the second arc edge s3 of the needle plug 32 are continuously transitioned. This technical means makes the thread unwinding process smoother, reduces the friction and jamming of the rope during the weaving process, and improves the weaving efficiency and the quality of the finished product.

[0069] The clampable base assembly 102 is a key part of the braider 100, which ensures that the braider can be firmly fixed on a workbench or other work surface. The assembly consists of a base 50 and a clamping member 60, wherein the base 50 is provided with an upwardly protruding connecting column, and a threaded hole is provided in the middle for cooperating with a threaded rod 62 to achieve stable installation and adjustment of the clamping member 60. The clamping member 60 includes a clamping plate 61 and a threaded rod 62, and the clamping plate 61 is connected to the base 50 through the threaded rod 62. The clamping area f between the two allows the braider to remain stable when fixed and provides sufficient space to adapt to work surfaces of different sizes.

[0070] 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 allows the clamp 60 to be easily installed and adjusted, providing great convenience for the user. The user can adjust the height and angle of the braider as needed to adapt to different working conditions and personal preferences to achieve the best braiding effect.

[0071] In summary, the technical means of the clampable base assembly 102 take into account stability, compatibility and user convenience, so that the braider 100 can work stably in various environments, while providing users with flexible adjustment options to adapt to different braiding needs and personal preferences. This carefully technical structure not only improves the practicality of the braider, but also enhances its durability and reliability, making it an ideal choice for braiding enthusiasts and professionals.

[0072] Furthermore, the cylinder 40 includes an upper cylinder member 41 and a lower cylinder member 42, and an oblique annular limit groove 313 is formed between the two cylinder members; the oblique annular limit groove 313 includes an upper limit inclined surface r1 and a lower limit inclined surface r2; these two inclined surfaces accurately control the up and down movement of the needle base 312, ensuring that the crochet needle can move accurately along a predetermined trajectory during the weaving process.

[0073] During the operation of the knitting machine, the needle foot 312 is located between the upper limit inclined surface r1 and the lower limit inclined surface r2. In the rising stage of the hook, the lower limit inclined surface r2 pushes the needle foot 312 upward, and in the descending stage, the upper limit inclined surface r1 pushes the needle foot 312 downward. This technical means enables the hook 30 to smoothly perform an up and down circular motion during knitting, thereby ensuring the continuity and uniformity of knitting.

[0074] In addition, the upper end of the lower cylinder 42 radially extends outwardly to form an inclined wall m, and the upper surface of the inclined wall m transitions coherently with the lower limit inclined surface r2, providing a smooth transition area, further ensuring the smoothness of the crochet movement. Moreover, the existence of the inclined wall m takes into account the reduction of friction and wear, prolonging the service life of the knitting device, and also makes the crochet more stable during fast knitting, reducing knitting errors caused by the shaking or displacement of the crochet. This kind of carefully technical oblique annular limit groove 313 and inclined wall m enable the knitting device 100 to maintain high quality standards of knitting works while knitting efficiently.

[0075] In summary, the unique oblique annular limiting groove 313 and the inclined wall m of the cylinder 40 provide precise motion control and a smooth motion path for the hook.

[0076] Preferably, a wire feed drum 43 is provided on the upper cylinder 41, and the opening of the wire feed drum 43 is a trumpet-shaped opening so that the wire entry area is open and has sufficient space, thereby facilitating the hand to cooperate. A notch k is provided on one side of the opening of the wire feed drum 43, and the function of the notch k is to further guide the wire, ensure that the wire can accurately enter the braiding area, and provide an additional tension control point during the braiding process.

[0077] Preferably, a wire port y is provided on the side wall of the wire inlet drum below the notch k to guide the wire into the wire inlet drum 43 along a predetermined trajectory, thereby ensuring the stability of the wire and reducing movement during the weaving process. A fixing plug p is provided at the wire port y. The function of this fixing plug p is to firmly fix the wire at the wire port y to prevent the wire from shifting during weaving. At the same time, by fixing the end of the wire by external force, the wire can be effectively tightened to ensure uniform tension during the weaving process, which is crucial for making high-quality woven products.

[0078] Preferably, the other end of the rope is clamped with a weight clamp 70, and the weight clamp 70 clamps the rope passing through the bottom of the clamping plate 61. This ensures that the rope is in a tight state during the braiding process and also helps to maintain the consistency of the braiding tension.

[0079] It should be noted that the weight of the weight clip 70 is carefully designed, ranging from 90 grams to 150 grams. This weight selection is based on many rounds of experiments and tests we conducted to find an optimal weight to ensure that the weight clip works perfectly with the braider 100. Through this precise weight configuration, we ensure stability and smoothness during braiding, so that the rope tension is just right, thereby improving the efficiency of braiding and the quality of the finished product.

[0080] Furthermore, vertically distributed convex strips g are distributed on the central column 20, and a moving groove g1 for the crochet needle 30 to move up and down is formed between two adjacent convex strips g. The coordinated use of the convex strips g and the moving groove g1 ensures that the crochet needle 30 can move accurately along a predetermined trajectory during the knitting process, thereby ensuring the uniformity and consistency of the knitting. Moreover, the stable movement path reduces the jitter and deviation of the crochet needle in high-speed knitting or complex knitting modes.

[0081] Preferably, an outer shell b is sleeved between the wire inlet drum 43 and the base 50. On the one hand, the outer shell b provides physical protection for the internal components between the wire inlet drum 43 and the base 50. On the other hand, the outer shell b helps to enhance the structural stability of the entire braider, and reduces vibration during use by fixing and supporting the wire inlet drum and the base.

[0082] The knitting method of the knitting device 100 with the hook instant switching mechanism, the schematic process of knitting is as follows Fig.16 and Fig.17 As shown, the specific steps include:

[0083] (1) First, evaluate the specific task of the knitting project and obtain the number and type of crochet hooks required; select a most suitable crochet hook instant switching mechanism 101 and assemble it with the clampable base assembly 102;

[0084] (2) Next, the braider is fixed at the target position by means of the clampable base assembly 102, thereby providing a stable operating platform for braiding.

[0085] (3) In preparation, the wire is guided through the wire guide port y on the side of the wire inlet barrel on the barrel body 40 and fixed with a fixing plug p to maintain the stability of the wire during braiding. The wire is then passed through the middle through hole of the center column 20 and the bottom through hole 62 of the clamping plate 61 of the clampable base assembly 102 in sequence, and finally the first end of the wire is clamped with a weight clamp 70 to provide the necessary tension, and braiding is ready to begin.

[0086] (4) When the knitting process starts, confirm that the needle latches 32 of all the hooks 30 are in the open state, the thread enters the hook portion of the first hook 3a in the ascending state, and at the same time, the handle 10 of the crank assembly 103 is turned to drive the first hook 3a to rotate and move downward;

[0087] (5) Continue to shake the handle 10, the rope avoids the second hook 3b and enters the hook of the third hook 3c. At the same time, continue to shake the handle 10, and the third hook 3c rotates and moves downward;

[0088] (6) Repeat step (5) until the first crochet needle 3a moves up to the raised state again, at which time the thread at the hook portion of the first crochet needle 3a drives the needle latch 32 to rotate until it is fully opened, so that the thread at the hook portion 311 slides off, and at the same time, the hook portion 311 of the first crochet needle 3a hooks the thread again;

[0089] (7) Continue to shake the handle 10, and the first crochet needle 3a moves downward. At this time, the rope thread that slides down from the first crochet needle 3a in step (6) applies an upward force to the needle latch 32, so as to drive the needle latch 32 to rotate upward to close with the hook portion, and at the same time, the rope thread that slides down passes over the top wall of the hook portion 311; the rest of the crochet needles 30 are driven by the external force of the shaking handle 10, and follow the first crochet needle 3a to complete the action of this step in sequence;

[0090] (8) Finally, repeat step (7) until the knitting task is completed.
