Description

Technical Field

[0001] This utility model relates to the field of roving processing technology, specifically a twisting and winding device for roving. Background Technology

[0002] Textiles are products made through textile processing, including yarns, woven fabrics, knitted fabrics, and braided fabrics. At the beginning of the production of these textiles, a roving process is used to process slivers into rovings of different counts and twists for use in the spinning process. In this process, a roving frame is used. The main function of the roving frame is to draft and twist the yarn and wind it into a certain roll shape to meet the requirements of the spinning frame.

[0003] Existing roving twisting and winding devices typically twist the yarn before winding it. The twisting device and the winding device are two separate units, requiring separate drive units to provide power output, which results in high equipment manufacturing costs. Since twisting and winding need to be driven separately, there is energy loss during power transmission, resulting in high overall energy consumption and inconvenient maintenance. Furthermore, fly waste, short fibers, dust, and other debris from the yarn adhere to the twisted yarn, affecting the appearance, feel, and performance of the final product. Utility Model Content

[0004] The purpose of this utility model is to provide a twisting and winding device for roving, in order to solve the problems mentioned in the background art. Existing twisting and winding devices for roving usually twist the yarn before winding it. The twisting device and the winding device are two separate entities, requiring separate drive devices to provide power output, which leads to high equipment manufacturing costs. Since twisting and winding need to be driven separately, there is energy loss during power transmission, resulting in high overall energy consumption and inconvenient maintenance. In addition, fly waste, short fibers, dust and other debris on the yarn adhere to the twisted yarn, affecting the appearance, feel and performance of the final product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a twisting and winding device for roving, comprising a base and a twisting section:

[0006] The base has a support frame a on top and a support frame b on top of the base. The twisting section is located on the top of the base and has a rotating disk rotatably mounted on the side of the support frame a. The support frame b has a drive twisting roller, a transmission roller, and a take-up roller rotatably mounted on its interior. The support frame b has a power shaft rotatably mounted on its side. The power shaft is sequentially connected to the rotating disk, the drive twisting roller, the transmission roller, and the take-up roller. The support frame a has a motor on its side, and the output end of the motor is connected to the power shaft. The motor drives the power shaft to sequentially drive the rotating disk, the drive twisting roller, the transmission roller, and the take-up roller to operate.

[0007] By adopting the above technical solution, the twisting and winding processes can be integrated. A single motor drives the power shaft to rotate, which in turn synchronously drives the rotary table to unwind, the active twisting roller to twist, the transmission roller to convey, and the take-up roller to wind. This simplifies the transmission structure, reduces energy consumption and production costs, and ensures the synchronization of each process, thereby improving the quality stability of roving processing.

[0008] Preferably, the base also has a sleeve longitudinally disposed inside the support frame b, and the transmission roller is nested inside the sleeve and rotatably connected to the support frame b in the longitudinal direction.

[0009] By adopting the above technical solution, the sleeve can provide stable support and positioning for the drive roller, ensuring that the drive roller, active twisting roller and take-up roller maintain coaxiality and smooth operation when rotating at high speed.

[0010] Preferably, the twisting section also has a guide frame that is slidably nested outside the sleeve, and the guide frame is longitudinally slidably connected to the sleeve.

[0011] By adopting the above technical solution, the yarn conveying path can be precisely guided and adjusted by sliding the guide frame along the longitudinal direction of the sleeve, ensuring uniform tension of the yarn during twisting and winding.

[0012] Preferably, the twisting part also has a retaining tooth arranged around the side of the rotating disk, and a transmission gear is provided on the side of the power shaft, which meshes with the retaining tooth.

[0013] By adopting the above technical solution, the power shaft can be stably driven to the rotating disk through gear meshing transmission, ensuring that the rotation speed of the rotating disk is synchronized with the twisting and winding processes, thereby improving transmission efficiency and reliability.

[0014] Preferably, the twisting section also has six pay-off rollers disposed on the side of the rotating disk, and the six pay-off rollers are arranged in a central rotational symmetric structure around the rotation center of the rotating disk.

[0015] By adopting the above technical solution, multiple yarns can be fed out synchronously using six symmetrically distributed feed rollers, thereby improving production efficiency.

[0016] Preferably, the twisting section also has a threading frame disposed inside the support frame b, the threading frame having holes for coarse sand to pass through, and a cleaning plate disposed inside the support frame b, the cleaning plate having holes for scraping off fly filaments, short fibers, and dust from the yarn and collecting them in a storage groove on the side of the cleaning plate.

[0017] By adopting the above technical solution, the yarn can be positioned and guided by the threading frame to ensure the stability of the yarn path during processing; the cleaning plate can effectively remove fly shavings, short fibers and dust from the surface of the yarn, avoiding impurities from affecting the yarn quality and subsequent processing. The collected impurities can be cleaned regularly to keep the equipment clean.

[0018] Preferably, the twisting section also has a driven twisting roller that is longitudinally rotatably disposed inside the support frame b, the driven twisting roller abutting against the driving twisting roller.

[0019] By adopting the above technical solution, a twisting nip can be formed by the cooperation of the active twisting roller and the driven twisting roller, so as to achieve effective twisting of the yarn and ensure uniform twist.

[0020] Preferably, the twisting section also has a reciprocating groove formed on the surface of the drive roller, and the guide frame is embedded in the reciprocating groove and slidably connected to the drive roller.

[0021] By adopting the above technical solution, the guide frame can slide back and forth along the reciprocating groove by rotating the transmission roller, which can ensure that the yarn is layered and uniform in density when winding, and avoid yarn overlap or accumulation.

[0022] Preferably, the active twisting roller, drive roller, and take-up roller are all provided with bevel teeth at one end near the power shaft, and are sequentially engaged with bevel teeth a, b, and c provided on the power shaft.

[0023] By adopting the above technical solution, the synchronous drive of the power shaft to the active twisting roller, the transmission roller and the take-up roller can be achieved through bevel gear transmission.

[0024] Compared with the prior art, the beneficial effects of this utility model are: by setting up a twisting section, the twisting and winding can be integrated into one drive. A single motor drives the power shaft to rotate, thereby synchronously driving the rotary table to unwind, the active twisting roller to twist, the transmission roller to convey, and the take-up roller to wind. This simplifies the transmission structure, reduces energy consumption and production costs, and at the same time ensures the synchronization of each process and improves the quality stability of roving processing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example; please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a technical solution: a twisting and winding device for roving, comprising a base 1 and a twisting section 2.

[0032] The base 1 is used to install the components of the entire roving twisting and winding device. In order to further assist in the installation of the roving twisting and winding device, the support frame a101 is connected to the top of the base 1 by bolts or welding, and the support frame b102 is also connected to the top of the base 1 by the same installation structure.

[0033] To simplify the transmission structure, a twisting section 2 is provided on the base 1. The twisting section 2 includes a rotating disk 201, an active twisting roller 211, a transmission roller 214, a take-up roller 217, and a power shaft 204. Specifically, the rotating disk 201 is rotatably mounted on the side of the support frame a101. At the same time, the active twisting roller 211, the transmission roller 214, and the take-up roller 217 all rotate longitudinally inside the support frame b102. The side of the support frame b102 is also laterally rotatably connected to the power shaft 204. It should be noted that during specific installation, the power shaft 204 needs to be engaged and connected to the rotating disk 201, the active twisting roller 211, the transmission roller 214, and the take-up roller 217 in sequence.

[0034] A motor 209 is detachably connected to the side of the support frame a101 via bolts, flanges, etc. In actual use, in order to drive the power shaft 204 to rotate, the output end of the motor 209 is fixedly connected to the power shaft 204. It should be noted that the working principle of the motor 209 is based on electromagnetic induction and Lorentz force. The motor 209 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the existing technology and will not be elaborated further below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven, so as to realize the integrated drive of twisting and winding.

[0035] When in use, the above-mentioned components drive the power shaft 204 to rotate via a single motor 209, which in turn synchronously drives the rotary disk 201 to feed yarn, the active twisting roller 211 to twist, the transmission roller 214 to convey yarn, and the take-up roller 217 to wind yarn. This simplifies the transmission structure, reduces energy consumption and production costs, and ensures the synchronization of each process, thereby improving the quality stability of roving processing.

[0036] In some embodiments, the twisting section 2 may also include a power shaft 204 and a drive roller 214.

[0037] To increase the stability of the sleeve 103 during use, the sleeve 103 is first fixedly installed inside the support frame b102. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The transmission roller 214 is nested in the sleeve 103, so that it is longitudinally rotatably connected to the support frame b102. During use, the sleeve 103 provides stable support and positioning for the transmission roller 214, ensuring the coaxiality and smooth operation of the transmission roller 214 when rotating at high speed.

[0038] In order to achieve precise guidance and adjustment of the yarn conveying path, a guide frame 216 is longitudinally slidably arranged outside the sleeve 103. The longitudinal sliding connection between the sleeve 103 and the guide frame 216 allows the guide frame 216 to slide longitudinally along the direction of the sleeve 103, thereby achieving precise guidance and adjustment of the yarn conveying path while ensuring the uniformity of yarn tension during twisting and winding.

[0039] The cleat 202 is arranged around the side of the rotating disk 201. The side of the power shaft 204 is provided with a transmission gear 205 that meshes with the cleat 202. In use, the power shaft 204 can stably drive the rotating disk 201 through gear meshing, ensuring that the rotation speed of the rotating disk 201 is synchronized with the twisting and winding process, thereby improving transmission efficiency and reliability.

[0040] It should be noted that the six pay-off rollers 203 are rotatably arranged on the side of the rotating disk 201, and the six pay-off rollers 203 are in a central rotational symmetric structure around the rotation center of the rotating disk 201. In use, the six symmetrically distributed pay-off rollers 203 will realize the synchronous pay-off of multiple yarns, further improving production efficiency.

[0041] The threading frame 210 is fixedly installed inside the support frame b102. It is worth noting that the fixing method is an existing detachable fixing method, such as bolt connection, snap connection, etc. At the same time, the threading frame 210 also has holes for coarse sand to pass through. The cleaning plate 213 is installed inside the support frame b102. The cleaning plate 213 also has holes for scraping off fly filaments, short fibers, and dust from the yarn. The scraped fly filaments, short fibers, and dust will be collected in the storage groove on the side of the cleaning plate 213.

[0042] It should be noted that the yarn can be positioned and guided by the threading frame 210 during use to ensure the stability of the yarn path during processing; the cleaning plate 213 can effectively remove fly, short fibers and dust from the surface of the yarn, preventing impurities from affecting the yarn quality and subsequent processing, and the collection tank for collecting impurities can be cleaned regularly to keep the equipment clean.

[0043] The driven twisting roller 212 is rotatably disposed inside the support frame b102. It is worth noting that the driven twisting roller 212 abuts against the active twisting roller 211. In actual use, the active twisting roller 211 and the driven twisting roller 212 cooperate to form a twisting nip, thereby achieving effective twisting of the yarn and ensuring uniform twist.

[0044] The twisting section 2 also has a reciprocating groove 215, a guide frame 216, and a drive roller 214. The reciprocating groove 215 is formed on the surface of the drive roller 214. It should be noted that the guide frame 216 is embedded in the reciprocating groove 215 and is slidably connected to the drive roller at a distance of 214. The guide frame 216 can slide back and forth along the reciprocating groove 215 by the rotation of the drive roller 214, which can ensure that the yarn is layered and uniform in density during winding, and avoid yarn overlap or accumulation.

[0045] The active twisting roller 211, the drive roller 214, and the take-up roller 217 are all provided with bevel teeth, and the bevel teeth are set at one end close to the drive shaft 204. Specifically, the bevel teeth on the active twisting roller 211, the drive roller 214, and the take-up roller 217 will mesh with the bevel teeth a206, b207, and c208 provided on the drive shaft 204 in sequence. The synchronous drive of the active twisting roller 211, the drive roller 214, and the take-up roller 217 by the drive shaft 204 can be achieved through bevel gear transmission.

[0046] Working principle: First, the device is powered on, and the motor 209 is started to drive the power shaft 204 to rotate. The power shaft 204 meshes with the tooth 202 of the rotating disk 201 through the transmission gear 205, driving the rotating disk 201 to rotate, so that the six symmetrically distributed pay-off rollers 203 release the roving synchronously. At the same time, the power shaft 204 drives the active twisting roller 211, the transmission roller 214 and the take-up roller 217 to rotate through the bevel teeth a206, b207 and c208 respectively. After the roving is drawn out from the pay-off roller 203, it is positioned through the guide hole of the threader 210 and enters the twisting jaw formed by the active twisting roller 211 and the driven twisting roller 212 for twisting. During the twisting process, the cleaning holes of the cleaning plate 213 continuously scrape away fly shavings and impurities from the yarn surface and collect them into the collection trough. The twisted roving is conveyed by the drive roller 214. When the drive roller 214 rotates, the reciprocating grooves 215 on its surface drive the guide frame 216 to perform regular reciprocating motion, so that the yarn is evenly distributed on the take-up roller 217. The sleeve 103 provides stable support for the drive roller 214 to ensure transmission accuracy; the sliding of the guide frame 216 along the sleeve 103 ensures that the yarn tension is constant.

[0047] Throughout the process, a single motor 209 drives the simultaneous operation of pay-off, twisting, cleaning, conveying, and winding. Each component maintains a precise speed ratio through gear meshing, ensuring uniform twist and neat winding of the roving. After the equipment stops, the collection slot of the removable cleaning plate 213 is used for cleaning impurities, making maintenance convenient.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
