Description

Technical Field

[0001] This application relates to the field of color development and prototyping technology, and in particular to a prototyping yarn twisting device. Background Technology

[0002] In the color development and confirmation process of the textile and chemical fiber industry, yarn twisting technology for sampling is a crucial preliminary step. Its core function is to simulate the twisting process of mass production by twisting small batches of yarn samples, allowing sampling personnel to intuitively and accurately evaluate the color depth and hue of the yarn at a specific twist level. This technology serves as a key bridge connecting design concepts and mass production; the accuracy of its results directly affects customer confirmation of the color, making it indispensable for shortening development cycles and improving sampling success rates.

[0003] Currently, a simple twisting device is commonly used in the industry for yarn sampling and twisting. This type of device typically consists of a drive motor, a yarn spindle support, and a guiding mechanism. Its principle is as follows: the drive motor rotates a yarn spindle, while the operator holds the other end of the yarn and manually pulls and controls the tension, causing the yarn to twist during rotation. This device, by controlling the motor's speed and running time, achieves a certain degree of preliminary control over the yarn twist, offering improved efficiency compared to completely manual twisting.

[0004] However, the stability and uniformity of the twisting process using the aforementioned twisting device are highly dependent on the operator's skill and experience. Since the yarn tension is entirely controlled manually, it is difficult to maintain a constant level, resulting in poor uniformity of twist applied to the yarn. Uneven twisting, often characterized by sections that are tight and sections that are loose, can easily occur on the same section of yarn. This uneven twisting directly alters the yarn's color rendering characteristics, preventing sampling personnel from obtaining stable and accurate color results to precisely judge depth and hue. Ultimately, this can lead to significant discrepancies between the sample and the bulk product, causing customers to refuse sample confirmation. This not only wastes materials but also severely impacts sampling efficiency and the smooth progress of orders. Summary of the Invention

[0005] In order to obtain sample yarn with uniform twist and stable color performance, so as to improve the accuracy of color confirmation and sampling efficiency, this application provides a sample yarn twisting device.

[0006] This application provides a sample yarn twisting device, which adopts the following technical solution:

[0007] A sample yarn twisting device includes a mounting box and a support base fixed below the mounting box. A yarn hook is rotatably mounted on the side wall of the mounting box. The mounting box integrates a control mechanism for driving the yarn hook to rotate forward and backward. The support base is provided with a clamping mechanism for fixing the end of the yarn to be twisted and an adjusting mechanism for adjusting the distance between the clamping mechanism and the yarn hook.

[0008] By adopting the above technical solution, the control mechanism can provide stable and controllable rotational twisting power to the yarn hook, replacing traditional manual twisting or simple motor drive, ensuring a stable source of twist application. Meanwhile, the clamping mechanism on the support base reliably fixes the other end of the yarn, while the adjustment mechanism precisely adjusts the yarn length between the clamping mechanism and the yarn hook. The coordinated work of these three components ensures the controllability of yarn tension and twisting length during the twisting process, laying a structural foundation for obtaining uniform and consistent yarn twist.

[0009] Optionally, the control mechanism includes a motor disposed in the mounting box, a power switch, a forward / reverse switch and a timer respectively disposed on the top of the mounting box, the output end of the motor being coaxially fixed to the end of the yarn hook near the mounting box, a control system being disposed in the mounting box, the control system being electrically connected to the motor, the power switch, the forward / reverse switch and the timer respectively, and the control system, the motor and the timer being connected to an external power source.

[0010] By adopting the above technical solution, the control mechanism integrates the motor, power switch, forward / reverse switch, and timer through a control system, achieving precise and programmed control of the twisting process. Operators can conveniently set the motor's rotation direction via the forward / reverse switch to meet the process requirements of single-twist or multi-ply twisting. Simultaneously, by precisely setting the twisting time through the timer, the total number of twists applied to the yarn is indirectly and stably controlled, thereby achieving quantitative and standardized control of the yarn twist degree and effectively avoiding uneven twist caused by human error.

[0011] Optionally, a storage battery is provided inside the mounting box, and the storage battery is electrically connected to the control system, the motor and the timer respectively.

[0012] By adopting the above technical solution, a storage battery is installed inside the mounting box, and an electrical connection is established between the storage battery and the control system, motor, and timer, making the entire twisting device independent of its dependence on a fixed external power source. This design gives the device portability, enabling it to be used flexibly in various environments without an external power source, greatly expanding the device's applicable scenarios and facilitating sample making by sample makers to perform yarn twisting and sampling work anytime, anywhere.

[0013] Optionally, the clamping mechanism includes a clamping seat, a clamping plate, a spiral rod, and a knob. The clamping seat is mounted on the support base, and the spiral rod is threadedly connected to the clamping seat. The two ends of the spiral rod are respectively fixedly connected to the clamping plate and the knob, and a clamping space for clamping yarn is formed between the clamping plate and the clamping seat.

[0014] By adopting the above technical solution, rotating the knob drives the screw rod to move forward and backward within the clamping seat, thereby driving the clamping plate closer to or further away from the clamping seat to adjust the clamping space. This structure utilizes the self-locking characteristic of the screw drive to generate a strong and stable clamping force, ensuring that the yarn end is firmly fixed between the clamping seat and the clamping plate during twisting. This effectively prevents the yarn from slipping or loosening under stress, providing a reliable end-fixing guarantee for a stable twisting process.

[0015] Optionally, the adjusting mechanism includes a first adjusting rod connected to the support base, a second adjusting rod rotatably connected to the end of the first adjusting rod away from the support base, and an adjusting assembly for adjusting the angle between the first adjusting rod and the second adjusting rod, wherein the clamping base is fixed to the end of the second adjusting rod away from the first adjusting rod.

[0016] By adopting the above technical solution, the yarn adjustment mechanism, through the first adjusting rod, the second adjusting rod, and the adjusting components between them, forms a multi-directional adjustable support arm. This structure allows the clamping mechanism fixed to the end of the second adjusting rod to not only change the distance from the yarn hook in the horizontal direction to adapt to different twisting requirements, but also to flexibly adjust the yarn direction and tension angle in three-dimensional space by changing the angle between the first and second adjusting rods, thereby more precisely simulating the yarn path state in actual production.

[0017] Optionally, the adjustment assembly includes a first adjustment screw, a second adjustment screw, and an adjustment sleeve. One end of the first adjustment screw and the second adjustment screw are respectively rotatably connected to the side wall of the first adjustment rod and the second adjustment rod, and the rotation points are reserved with a free movement allowance.

[0018] The first adjusting screw and the second adjusting screw are collinear and have opposite threads. The adjusting sleeve is threaded onto the ends of the first adjusting screw and the second adjusting screw that are close to each other, and is adapted to the threads on the outer peripheral walls of the first adjusting screw and the second adjusting screw, respectively.

[0019] By adopting the above technical solution, the adjusting assembly, through a first and second adjusting screw with opposite thread directions, and an adjusting sleeve that is compatible with both, constitutes a precise linear drive mechanism. Rotating the adjusting sleeve synchronously drives the first and second adjusting screws to move closer or further apart, thereby precisely and smoothly changing the angle between the first and second adjusting rods. This structure has the advantages of smooth transmission, high adjustment accuracy, and good self-locking performance, enabling fine-tuning and reliable locking of the spatial position of the clamping mechanism, further optimizing the control of yarn tension.

[0020] Optionally, the first adjusting rod can be detachably fixed to the support base by bolts.

[0021] By adopting the above technical solution, the first adjusting rod is detachably fixed to the support base with bolts, providing a flexible installation method for the entire adjusting mechanism. When a large adjustment or storage is required, the bolts can be loosened, and the entire adjusting arm can be removed from the support base, making the device structure more compact and easy to transport and store. When needed, it can be quickly installed and fixed, balancing the stability of the device with ease of use.

[0022] Optionally, the support base is further provided with a lifting component for driving the mounting box to rise and fall, and a guide rod for guiding the rise and fall of the mounting box on the support base.

[0023] By adopting the above technical solution, a lifting component and a guide rod are installed on the support base, allowing the mounting box and its yarn hooks to move vertically up and down. This design allows the operator to flexibly adjust the height of the twisting power point according to the yarn thickness, the specific requirements of the twisting process, or personal operating habits, thereby optimizing the yarn's sag angle and tension distribution during twisting. The guide rod ensures the smoothness and straightness of the lifting process, preventing the mounting box from deflecting during lifting and ensuring the consistency and stability of the twisting axis.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By integrating the motor, control system, timer, and forward / reverse switch into the mounting box, a unified control mechanism is formed, thereby achieving precise electronic control of the yarn hook rotation direction and rotation time. This design transforms the twisting process from an experience-based operation into a quantifiable and repeatable standardized process, fundamentally ensuring the consistency of twist in each sample and providing a prerequisite for accurate color evaluation.

[0026] 2. The clamping mechanism uses the cooperation of the screw rod and the clamping plate to provide a firm and reliable fixation for the yarn end, preventing slippage during the twisting process. The adjustment mechanism, through the multi-stage adjustable adjustment rod and the precision threaded adjustment component, allows the operator to flexibly and accurately adjust the distance and angle between the yarn fixing point and the rotation point in three-dimensional space, thereby achieving optimized control of yarn tension and twisting path, and further ensuring the uniform distribution of twist along the yarn length.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.

[0033] This application discloses a sample yarn twisting device.

[0034] Reference Figure 1 and Figure 2 A sample yarn twisting device includes a mounting box 1 and a support base 2 fixed below the mounting box 1. A yarn hook 3 is rotatably mounted on the side wall of the mounting box 1. The mounting box 1 integrates a control mechanism 4 for driving the yarn hook 3 to rotate forward and backward. The support base 2 is provided with a clamping mechanism 5 for fixing the end of the yarn to be twisted and a distance adjustment mechanism 6 for adjusting the distance between the clamping mechanism 5 and the yarn hook 3.

[0035] The control mechanism 4 provides stable and controllable rotational twisting power to the yarn hook 3, replacing traditional manual twisting or simple motor drive, ensuring a stable source of twist application. Meanwhile, the clamping mechanism 5 on the support base 2 reliably secures the other end of the yarn, while the adjusting mechanism 6 precisely adjusts the yarn length between the clamping mechanism 5 and the yarn hook 3. The coordinated operation of these three components ensures the controllability of yarn tension and twisting length during the twisting process, laying the structural foundation for obtaining uniform and consistent yarn twist.

[0036] Reference Figure 1 and Figure 2 The control mechanism 4 includes a motor installed in the mounting box 1, a power switch 41, a forward / reverse switch 42, and a timer 43 respectively installed on the top of the mounting box 1. The output end of the motor is coaxially fixed with the end of the yarn hook 3 near the mounting box 1. A control system is installed in the mounting box 1. The control system is electrically connected to the motor, the power switch 41, the forward / reverse switch 42, and the timer 43 respectively. The control system, the motor, and the timer 43 are all connected to an external power source.

[0037] The control mechanism 4 integrates the motor, power switch 41, forward / reverse switch 42, and timer 43 through a control system, achieving precise and programmed control of the twisting process. Operators can conveniently set the motor's rotation direction via the forward / reverse switch 42 to meet the process requirements of single-twist or multi-ply twisting. Simultaneously, the timer 43 precisely sets the twisting time, indirectly and stably controlling the total number of twists applied to the yarn, thereby achieving quantitative and standardized control of the yarn twist degree and effectively avoiding uneven twist caused by human error.

[0038] The mounting box 1 contains a storage battery, which is electrically connected to the control system, motor, and timer 43. By placing the battery inside the mounting box 1 and establishing electrical connections between the battery and the control system, motor, and timer 43, the entire twisting device is freed from dependence on a fixed external power source. This design gives the device portability, allowing for flexible use in various environments without an external power source, greatly expanding its applicability and facilitating yarn twisting sampling work for sampling personnel anytime, anywhere.

[0039] Reference Figure 2 and Figure 3 The clamping mechanism 5 includes a clamping seat 51, a clamping plate 52, a spiral rod 53, and a knob 54. The clamping seat 51 is mounted on the support base 2. The spiral rod 53 is threadedly connected to the clamping seat 51. The two ends of the spiral rod 53 are fixedly connected to the clamping plate 52 and the knob 54, respectively. A clamping space for clamping yarn is formed between the clamping plate 52 and the clamping seat 51.

[0040] Rotating the knob 54 drives the screw rod 53 to move forward and backward within the clamping seat 51, thereby driving the clamping plate 52 to move closer to or further away from the clamping seat 51 to adjust the clamping space. This structure utilizes the self-locking characteristic of the screw drive to generate a strong and stable clamping force, ensuring that the yarn end is firmly fixed between the clamping seat 51 and the clamping plate 52 during the twisting process. This effectively prevents the yarn from slipping or loosening during the stress process, providing a reliable end-fixing guarantee for a stable twisting process.

[0041] Reference Figure 2 and Figure 3 The adjusting mechanism 6 includes a first adjusting rod 61 connected to the support base 2, a second adjusting rod 62 rotatably connected to the end of the first adjusting rod 61 away from the support base 2, and an adjusting assembly for adjusting the angle between the first adjusting rod 61 and the second adjusting rod 62. The clamping seat 51 is fixed to the end of the second adjusting rod 62 away from the first adjusting rod 61.

[0042] The adjusting mechanism 6, through the first adjusting rod 61, the second adjusting rod 62, and the adjusting components between them, forms a multi-directionally adjustable support arm. This structure allows the clamping mechanism 5, fixed to the end of the second adjusting rod 62, to not only change its distance from the yarn hook 3 in the horizontal direction to adapt to different twisting requirements, but also to flexibly adjust the yarn direction and tension angle in three-dimensional space by changing the angle between the first adjusting rod 61 and the second adjusting rod 62, thereby more precisely simulating the yarn path state in actual production.

[0043] Reference Figure 2 and Figure 3 The adjustment assembly includes a first adjusting screw 63, a second adjusting screw 64, and an adjusting sleeve 65. One end of the first adjusting screw 63 and the second adjusting screw 64 are respectively rotatably connected to the side wall of the first adjusting rod 61 and the second adjusting rod 62, and the rotatable parts are reserved with a free movement margin.

[0044] The first adjusting screw 63 and the second adjusting screw 64 are collinear and have opposite threads. The adjusting sleeve 65 is threaded onto the ends of the first adjusting screw 63 and the second adjusting screw 64 that are close to each other, and is adapted to the threads on the outer peripheral walls of the first adjusting screw 63 and the second adjusting screw 64 respectively.

[0045] The adjusting assembly, through a first adjusting screw 63 and a second adjusting screw 64 with opposite thread directions, and an adjusting sleeve 65 that is adapted to both, constitutes a precise linear drive mechanism. Rotating the adjusting sleeve 65 synchronously drives the first adjusting screw 63 and the second adjusting screw 64 to move closer or further apart, thereby precisely and smoothly changing the included angle between the first adjusting rod 61 and the second adjusting rod 62. This structure has the advantages of smooth transmission, high adjustment accuracy, and good self-locking performance, enabling fine adjustment and reliable locking of the spatial position of the clamping mechanism 5, further optimizing the control of yarn tension.

[0046] The first adjusting rod 61 is detachably fixed to the support base 2 by bolts, providing a flexible installation method for the entire adjusting mechanism 6. When a large adjustment or storage is required, the bolts can be loosened, and the entire adjusting arm can be removed from the support base 2, making the device structure more compact and easy to transport and store. When needed, it can be quickly installed and fixed, balancing the stability of the device with ease of use.

[0047] Reference Figure 1 and Figure 2 The support base 2 is also provided with a lifting component 7 for driving the installation box 1 to rise and fall, and a guide rod 8 for guiding the rise and fall of the installation box 1 on the support base 2. In this embodiment, the lifting component 7 adopts a mechanical press-type plunger oil pump, which can be manually adjusted for lifting. In other feasible embodiments, an electric telescopic rod, an electric hydraulic cylinder, etc. can also be adopted.

[0048] A lifting mechanism 7 and a guide rod 8 are installed on the support base 2, allowing the mounting box 1 and its yarn hook 3 to move vertically up and down. This design allows the operator to flexibly adjust the height of the twisting power point according to the yarn thickness, the specific requirements of the twisting process, or personal operating habits, thereby optimizing the yarn's sag angle and tension distribution during twisting. The guide rod 8 ensures the smoothness and straightness of the lifting process, preventing the mounting box 1 from deflecting during lifting and ensuring the consistency and stability of the twisting axis.

[0049] The implementation principle of the sample yarn twisting device in this application embodiment is as follows: When twisting, the operator first securely fixes one end of the yarn with the clamping mechanism 5 and hangs the other end on the yarn hook 3, and adjusts it to a suitable tension and length through the adjustment mechanism 6. The timer 43 is set to the required twisting time to control the twist degree. The forward and reverse switch 42 is adjusted to control the forward and reverse rotation direction of the motor. When twisting a single yarn, the forward and reverse switch 42 is in the forward position. The device power is turned on to start the motor. The motor drives the yarn hook 3 to rotate in the forward direction, thereby achieving the yarn twisting effect.

[0050] The twisting process involves folding the single-twisted yarn in half after completing the single-twisting step, dividing it into two single-twisted yarns. One end of the yarn is fixed by the clamping mechanism 5, and the other end is fixed to the yarn hook 3 of the device. The timer 43 is adjusted, the forward / reverse switch 42 is in the reverse position, the device power is turned on, and the motor is started. The motor drives the yarn hook 3 to rotate in the reverse direction, thereby achieving the twisting effect of the yarn.

[0051] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
