Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing technology, and in particular to a telescopic manual crank tool for tie-dyeing. Background Technology

[0002] Tie-dyeing is a traditional Chinese hand-dyeing technique with a long history, and the ancient dye vat is its core tool. However, the traditional dyeing process relies entirely on manual operation by artisans, which presents many technical bottlenecks. First, the dyeing process requires the cooperation of multiple people, who use tools such as bamboo poles to repeatedly stir the fabric. It is difficult for the operators to maintain uniform force and speed, which easily leads to uneven dyeing of the fabric, affecting the appearance of the finished product. In addition, it is time-consuming, labor-intensive, and wasteful of materials.

[0003] Secondly, the dyeing, oxidation, and washing processes in traditional techniques are separate. After the fabric is dyed in the dye vat, it needs to be removed and moved elsewhere for oxidation. This process is not only cumbersome and inefficient, but the manual turning of the fabric during oxidation easily leads to uneven oxidation, resulting in color defects. Especially for advanced techniques such as "hanging dyeing gradient," which require the fabric to be precisely positioned and moved up and down at a uniform speed in the dye bath, traditional methods rely entirely on the craftsman's feel and experience, making it difficult to achieve precise control and repeatability. Furthermore, prolonged operation can easily lead to joint fatigue and injury for the operator.

[0004] Therefore, there is a lack of an integrated tool in the existing technology that can integrate dyeing, stirring and oxidation functions, adapt to dyeing vats of different sizes, and achieve uniform dyeing and precise gradient effects. This has become a technical problem that restricts the efficiency improvement and healthy inheritance of traditional tie-dyeing techniques. Utility Model Content

[0005] The purpose of this invention is to provide a telescopic manual crank tool for tie-dyeing, which aims to solve the technical problems existing in the traditional tie-dyeing process, such as complicated procedures, discontinuous operation, poor dyeing uniformity, poor oxidation effect, high labor intensity for craftsmen, and inability to achieve precise gradient dyeing.

[0006] This utility model is achieved using the following technical solution: a telescopic manual crank tool for tie-dyeing, characterized in that it includes a central support rod assembly, which is composed of at least one set of relatively slidable inner fixedly connected support arms and outer telescopic arms to achieve telescopic adjustment of the overall width of the tool; a rotary drive mechanism, which includes a rotary crank disposed at the top of the tool and a fixed handle connected thereto, for manual drive; a linkage transmission mechanism, which connects the rotary drive mechanism to the central support rod assembly to synchronously transmit the rotation of the rotary crank to the entire support rod assembly; at least one fabric suspension unit, which is movably disposed on the outer telescopic arm via a lasso sliding buckle, for suspending and driving the fabric to rotate; and a fixed base, which is connected to the bottom of the central support rod assembly to provide stable support for the tool.

[0007] Furthermore, the inner fixed connection support arm is provided with a sliding rod track, the inner side of the outer telescopic arm is provided with a telescopic arm positioning slider, and the telescopic arm positioning slider is slidably embedded in the sliding rod track; the outer side of the outer telescopic arm is also provided with a sliding rod track, and the lasso sliding buckle is slidably set on the sliding rod track.

[0008] Furthermore, the positioning and locking mechanism includes a spring-loaded positioning buckle disposed on the lasso sliding buckle and a fixed slot disposed on the top surface of the outer telescopic arm. The spring-loaded positioning buckle can selectively engage with the fixed slot to fix the position of the lasso sliding buckle. The positioning and locking mechanism includes a screw and a bolt knob. By tightening the bolt knob, the screw is pressed into the screw positioning groove to lock the relative position of the outer telescopic arm and the inner fixed connection support arm.

[0009] Furthermore, the fabric suspension unit includes a hook chain, a hook fixing block, and a rolling roller; the hook chain connects the lasso sliding buckle to the hook fixing block, and the rolling roller is installed at the bottom of the hook fixing block via a pulley-linked fixing rod; the side end of the outer telescopic arm is provided with fixing bolt holes for fixing the binding thread of the fabric.

[0010] Furthermore, the fabric binding thread is fixed to the fixing bolt hole and passes around the rolling roller, so as to realize the up and down movement of the fabric in the dye liquor for gradient dyeing, and to perform suspension oxidation after the fabric is lifted out of the dye liquor.

[0011] Furthermore, the height of the central support rod assembly is adjustable; specifically, the height of the main body is adjusted by sliding the outer telescopic arm relative to the inner fixed support arm, and fine-tuning is performed by connecting the fixed base via an external telescopic fixing rod.

[0012] Furthermore, the central support rod assembly is a multi-stage telescopic structure, including multiple inner fixed connection support arms and outer telescopic arms that are nested together in sequence, to expand the telescopic adjustment range of the tool.

[0013] Furthermore, the top of the rotating rocker arm of the rotary drive mechanism is provided with a handle sleeve, and the fixed handles are symmetrically arranged on both sides of the tool.

[0014] Furthermore, the linkage transmission mechanism includes a rocker fixed shaft, a fixed handle connecting block, a rotating rod connecting fixed block, and a rotating connecting fixed block, which are used to synchronously transmit the rotation of the rotating rocker to all the inner fixed connecting support arms and the outer telescopic arm.

[0015] The telescopic manual crank tool for tie-dyeing described in this utility model has the following advantages: Through innovative structural design, multiple separation processes such as stirring, gradient control, and oxidation treatment during dyeing are integrated into one tool, supporting single-person operation, greatly simplifying the process and improving production efficiency.

[0016] Driven by a manual crank, the fabric is rotated and stirred at a uniform speed in the dyeing vat via a transmission mechanism, ensuring even contact between the dye and the fabric and consistent coloring results. The combination of pulleys and bolt holes allows for precise control of the fabric's immersion depth and time, easily achieving ideal gradient dyeing effects.

[0017] By suspending the fabric above the liquid surface for oxidation, all surfaces of the fabric are simultaneously exposed to the air, achieving uniform oxidation from all angles. This effectively avoids the uneven oxidation problem caused by manual turning and improves product quality.

[0018] With a multi-stage telescopic arm structure, the overall width and height of the tool are adjustable, making it highly versatile and adaptable to traditional dyeing vats of different diameters and depths.

[0019] The tool features a comfortable grip and a fixed handle, with a stable base at the bottom. This ensures operational stability while significantly reducing the physical exertion and risk of joint injury for craftsmen, thus promoting the healthy inheritance of skills.

[0020] The tool's structural stability and reliability during operation are ensured by multiple positioning and locking mechanisms, including elastic buckles, fixed slots, and screw bolts, guaranteeing its durability for long-term use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0025] like Figure 1 As shown, this embodiment provides a telescopic manual crank tool for tie-dyeing. It mainly consists of a handle sleeve 1, a rotating crank 2, a crank fixing shaft 3, a first fixed handle 4, a second fixed handle 5, a connecting fixing shaft 6, an outer telescopic arm 7, an inner fixed connecting support arm 8, a fixing slot 9, a lasso sliding buckle 10, an elastic positioning buckle 11, a hook chain 12, a hook fixing block 13, a rolling roller 14, a pulley connecting fixing rod 15, an external telescopic fixing rod 16, a fixing base 17, a first fixing bolt hole 18, a bolt knob 19, a handle sleeve fixing assembly 20, a telescopic arm positioning slider 21, a sliding bar slide 22, a hook chain 23, and a hanging chain. The device consists of a hook 24, a roller 25, a second fixing bolt hole 26, a screw 33, a screw positioning groove 34, a fixing slot 35, a fixing handle connecting block 39, a rotating rod connecting fixing block 40, a rotating connecting fixing block 41, a second inner fixed connecting support arm 42, a third inner fixed connecting support arm 43, a fourth inner fixed connecting support arm 44, a fifth inner fixed connecting support arm 45, a sixth inner fixed connecting support arm 46, a second outer telescopic arm 47, a third outer telescopic arm 48, a fourth outer telescopic arm 49, a fifth outer telescopic arm 50, and a sixth outer telescopic arm 51.

[0026] The handle sleeve 1 is fixedly mounted on the top of the rotary rocker 2 via the handle sleeve fixing assembly 20. The lower end of the rotary rocker 2 is movably connected to the first fixed handle 4 and the second fixed handle 5 via the rocker fixing shaft 3. The first fixed handle 4 and the second fixed handle 5 are symmetrically arranged on both sides of the tool and are hinged to the inner fixed support arm 8 via the connecting fixing shaft 6. The fixed handle connecting block 39 and the rotary rod connecting fixing block 40 are connected via the rotating connecting fixing block 41 to realize power transmission.

[0027] The tool's central support rod employs a multi-stage telescopic structure. The inner fixed-connection support arm 8 is a hollow tubular structure with a sliding rail track 22 inside. The outer telescopic arm 7 is nested outside the inner fixed-connection support arm 8, and its inner ends are equipped with telescopic arm positioning sliders 21, which are embedded in the sliding rail track 22, allowing the outer telescopic arm 7 to slide along the inner fixed-connection support arm 8. A similar nesting connection relationship exists: the second inner fixed-connection support arm 42 is connected to the second outer telescopic arm 47; the third inner fixed-connection support arm 43 is connected to the third outer telescopic arm 48; the fourth inner fixed-connection support arm 44 is connected to the fourth outer telescopic arm 49; the fifth inner fixed-connection support arm 45 is connected to the fifth outer telescopic arm 50; and the sixth inner fixed-connection support arm 46 is connected to the sixth outer telescopic arm 51, collectively forming an adjustable-width support frame. The sliding rail track 22 is also located on the outside of the outer telescopic arm 7.

[0028] A lasso sliding buckle 10 is installed on the outer side wall of the telescopic boom, and the buckle can slide along the slide rail 22. The lasso sliding buckle 10 is connected to the hook fixing block 13 via the hook chain 12. A pulley connecting fixing rod 15 is fixed to the bottom of the hook fixing block 13, and a rolling roller 14 is mounted on the pulley connecting fixing rod 15 via a bearing. The hook 24 is connected to the lasso sliding buckle 10 via the hook chain 23. The first fixing bolt hole 18 and the second fixing bolt hole 26 are located at the side end of the telescopic boom.

[0029] A fixing groove 35 is provided on the top surface of the outer telescopic arm, which cooperates with the elastic positioning buckle 11 to realize the positioning of the lasso sliding buckle 10. The screw 33 is installed in the screw positioning groove 34 by the bolt knob 19. The positioning groove is located at the connection between the outer telescopic arm and the inner fixed connection support arm 8. The fixed base 17 is connected to the bottom of the inner fixed connection support arm 8 by the external telescopic fixing rod 16.

[0030] The tool works based on the linkage of a rotary joystick and a slider assembly, and the specific process is as follows: Rotary rocker linkage process: The user holds the first fixed handle 4 or the second fixed handle 5 with one hand, and rotates the handle sleeve 1 with the other hand, causing the rotary rocker 2 to rotate around the rocker fixed axis 3. The rotational motion of the rotary rocker 2 is transmitted to the handle connection structure through the rocker fixed axis 3, thereby driving the rotary rod connecting fixed block 40 to rotate. The rotary rod connecting fixed block 40 is fixedly connected to all the inner fixed connecting support arms, so these support arms rotate synchronously. The inner fixed connecting support arms are also connected to all the outer telescopic arms through the connecting fixed axis 6, thereby driving all the outer telescopic arms to rotate. The lasso sliding buckle 10, hook chain 12, hook fixing block 13 and rolling roller 14 on the outer telescopic arms rotate accordingly, so that the fabric suspended on the hook 24 or rolling roller 14 is stirred at a uniform speed in the dyeing vat. Since the rolling roller 14 can rotate freely, the fabric will not entangle during the rotation, ensuring that the dye contacts the fabric evenly and achieves uniform dyeing. At the same time, the fixed base 17 provides stable support, reduces the force exerted by the user, and conforms to ergonomics.

[0031] The sliding arm linkage process: The tool's width can be adjusted according to the diameter of the dyeing vat. By manually pulling the outer telescopic arm 7, the telescopic arm positioning slider 21 slides in the sliding rail 22, changing the overall span of the tool. After adjusting to the appropriate position, it is quickly fixed by engaging the elastic positioning buckle 11 with the fixing slot 35. For long-term use or scenarios requiring more secure fixation, the bolt knob 19 is used to tighten the screw 33, fixing the screw 33 in the screw positioning slot 34 to prevent the telescopic arm from falling off during rotation. Similarly, other telescopic arms can also be adjusted independently to adapt to dyeing vats of different sizes and support simultaneous dyeing of multiple fabrics in a single operation.

[0032] The integrated process of gradient dyeing and oxidation: The fabric is suspended on the rolling roller 14 by a binding line. The other end of the binding line passes through the first fixing bolt hole 18 or the second fixing bolt hole 26 and is fixed by the bolt knob 19. By manually pulling the binding line, the immersion depth of the fabric in the dye bath can be adjusted to achieve a "gradient" dyeing effect that allows for free vertical movement. After dyeing, the fabric is completely lifted to remove it from the dye bath, and the binding line is fixed using the first fixing bolt hole 18, allowing the fabric to undergo oxidation treatment while suspended in the air. Because the fabric is suspended, all sides are exposed to the air and come into full contact with carbon dioxide, achieving uniform oxidation from all angles and avoiding uneven oxidation caused by manual turning. After oxidation, the fabric can be re-immersed in the dye bath for re-dyeing according to the color requirements, completing the integrated "dyeing-stirring-oxidation-re-dyeing" operation and simplifying the process.

[0033] Height Adjustment Process: The telescopic structure of the central support rod allows the tool to adjust its height according to the depth of the dye bath and the dye level. By sliding the outer telescopic arm 7 relative to the inner fixed support arm 8, the length of the support rod is changed to ensure that the fabric is fully immersed in the dye solution. The external telescopic fixing rod 16 allows for fine-tuning of the height, enhancing the tool's flexibility.

[0034] Through the aforementioned structural design, this tool significantly optimizes the traditional tie-dyeing process. The telescopic integrated manual rotating rocker structure supports single-person operation, ensuring uniform dyeing; the fixed base enhances stability and reduces operational effort. The track-sliding mechanism allows for free length adjustment, adapting to various dyeing vat diameters. Slide rail slots and elastic buckles ensure stable fabric fixation, preventing slippage. Chain loops and positioning rollers enable gradient dyeing and uniform oxidation, improving dyeing precision. The height-adjustable central support rod adapts to different working scenarios. Overall, the tool reduces the labor intensity of artisans, improves operational efficiency, and preserves the essence of traditional techniques, achieving a convenient, efficient, comfortable, and practical integrated function.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Modifications and variations made by those skilled in the art without departing from the spirit and scope of this utility model should be protected within the scope of the appended claims.
