Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to a wet tensioner. Background Art

[0002] The yarn tensioner for knitting machines is a textile accessory that feeds yarn to knitting machines. It maintains constant yarn tension during the yarn feeding process, preventing yarn breakage due to uneven force. As an important accessory in textile machinery, the yarn feeder is gaining increasing attention.

[0003] The yarn commonly used for winding is glass fiber, which is shipped in cylindrical or conical balls. During winding, the yarn is continuously stretched, but it cannot be initially taut (tensioned). Instead, the yarn becomes loose and insufficiently tensed, affecting its proper function. Therefore, sufficient tension must be applied to the yarn for proper winding and use. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a wet tensioner, which can timely adjust the tension of the yarn and give the yarn sufficient tension so that the yarn can be wound and used normally.

[0005] According to an embodiment of the utility model, the wet tensioner includes a base plate, a transmission roller, a magnetic powder brake and a tension detection roller. There are multiple transmission rollers, and the multiple transmission rollers are rotatably arranged on the base plate and the rotation directions of adjacent transmission rollers are opposite. The yarn is wound on the roller surfaces of the multiple transmission rollers in sequence; the magnetic powder brake is arranged on the base plate, and the number of the magnetic powder brakes is the same as the number of the transmission rollers. One magnetic powder brake is connected to one transmission roller to provide torque to the transmission roller to which it is connected; the tension detection roller is arranged on the base plate, and the yarn is wound on the tension detection roller after passing through the roller surfaces of the multiple transmission rollers. The tension detection roller detects the tension of the yarn, and the magnetic powder brake adjusts the torque of the transmission roller according to the tension detected by the tension detection roller.

[0006] According to the wet tensioner of the embodiment of the present invention, by such an arrangement, at least the following beneficial effects can be achieved: the transmission roller transmits the yarn, and the yarn is wound on the tension detection roller after passing through multiple transmission rollers, applying a force to the tension detection roller. The tension detection roller detects the tension of the yarn passing through it and determines whether the tension on the yarn is large or small.

When the tension detection roller detects that the tension on the yarn is too large, the magnetic powder brake reduces the torque, causing the tension on the yarn to decrease. By such an arrangement, the tension on the yarn can reach the set value, giving the yarn sufficient tension so that the yarn can be wound and used normally.

[0007] According to some embodiments of the present invention, the transmission rollers are arranged in two rows, one above the other, on the base plate, and adjacent transmission rollers are located in the upper and lower rows, respectively.

[0008] According to some embodiments of the present invention, the transmission roller and the tension detection roller are arranged on one side of the substrate, and the magnetic powder brake is arranged on the other side of the substrate.

[0009] According to some embodiments of the present invention, the distance between the transmission rollers in the vertical or horizontal direction can be adjusted, thereby adjusting the wrap angle of the yarn wound around the transmission rollers.

[0028] Reference below Figures 1 to 4 The wet tensioner according to the embodiment of the present invention is described below.

[0029] According to an embodiment of the present utility model, a wet tensioner includes a substrate 100, a transmission roller 200, a magnetic powder brake 300 and a tension detection roller 400. A plurality of transmission rollers 200 are provided, and the plurality of transmission rollers 200 are rotatably provided on the substrate 100 and the rotation directions of adjacent transmission rollers 200 are opposite. The yarn is wound on the roller surfaces of the plurality of transmission rollers 200 in sequence; the magnetic powder brake 300 is provided on the substrate 100, and the number of the magnetic powder brake 300 is the same as the number of the transmission rollers 200. One magnetic powder brake 300 is connected to one transmission roller 200 to provide torque to the transmission roller 200 to which it is connected; the tension detection roller 400 is provided on the substrate 100, and the yarn is wound on the tension detection roller 400 after passing through the roller surfaces of the plurality of transmission rollers 200. The tension detection roller 400 detects the tension of the yarn, and the magnetic powder brake 300 adjusts the torque of the transmission roller 200 according to the tension detected by the tension detection roller 400.

[0030] For example Figures 1 to 3 As shown, a base plate 100 is provided with a transmission roller 200 and a tension detection roller 400 on one side, and a magnetic powder brake 300 on the other side. Each transmission roller 200 is connected to a magnetic powder brake 300 to provide torque. The transmission rollers 200 are rotatably mounted on the base plate 100, and adjacent transmission rollers 200 rotate in opposite directions, allowing the yarn to be wound around the transmission rollers 200 for transmission.

[0031] The magnetic powder brake 300 is connected to the drive roller 200 and provides torque to the drive roller 200, controlling the torque of the drive roller 200 and thereby increasing or decreasing the tension on the yarn passing through the drive roller 200. The tension detection roller 400 detects the tension of the yarn passing through it and determines whether the tension on the yarn is high or low. If the tension detection roller 400 detects that the tension on the yarn is too low, the magnetic powder brake 300 increases the torque, increasing the tension on the yarn. If the tension detection roller 400 detects that the tension on the yarn is too high, the magnetic powder brake 300 reduces the torque, reducing the tension on the yarn. This configuration ensures that the tension on the yarn reaches the set value, providing the yarn with sufficient tension for normal winding and use.

[0032] Furthermore, the maximum value of the tension applied to the yarn by the driving roller 200 can be increased by increasing the number of the driving rollers 200 and the magnetic powder brakes 300 .

[0033] According to the wet tensioner of the embodiment of the present invention, by being set up in this way, at least the following beneficial effects can be achieved: the tension on the yarn can reach the set value, giving the yarn sufficient tension so that the yarn can be wound and used normally.

[0034] In some specific embodiments of the present invention, the transmission rollers 200 are arranged in two rows, one above the other, on the base plate 100 , and adjacent transmission rollers 200 are located in the upper and lower rows, respectively.

[0035] For example Figure 1 and Figure 2 As shown, three drive rollers 200 are provided in two rows on the base plate 100, with two drive rollers 200 in the upper row and one drive roller 200 in the lower row. Adjacent drive rollers 200 are located in the upper and lower rows, respectively, and there is a height difference between adjacent drive rollers 200 to adjust the wrap angle of the yarn passing over the drive rollers 200.

[0036] In some specific embodiments of the present invention, the driving roller 200 and the tension detecting roller 400 are disposed on one side of the substrate 100 , and the magnetic powder brake 300 is disposed on the other side of the substrate 100 .

[0037] For example Figure 2 and Figure 3 As shown, the transmission roller 200 and the tension detection roller 400 are arranged on one side of the substrate 100, and the magnetic powder brake 300 is arranged on the other side of the substrate 100. Through such an arrangement, the yarn only needs to pass through the transmission roller 200 and the tension detection roller 400, and does not need to pass through the magnetic powder brake 300, and is not affected by the magnetic powder brake 300.

[0038] The magnetic powder brake 300 is on the other side of the substrate 100 and can be more conveniently connected to the driving roller 200 to provide torque to the driving roller 200 .

[0039] In some specific embodiments of the present invention, the distance between the transmission rollers 200 in the vertical or horizontal direction can be adjusted, thereby adjusting the wrap angle of the yarn wound around the transmission rollers 200 .

[0040] By adjusting the distance between the transmission rollers 200 in the vertical direction or the horizontal direction, the wrap angle of the yarn wound on the transmission rollers 200 can be adjusted, thereby providing better tension to the yarn.

[0041] In some specific embodiments of the present invention, a plurality of guide rollers 600 are further included. The plurality of guide rollers 600 are disposed on the base plate 100 and are used to adjust the yarn transmission direction.

[0042] For example Figure 1 and Figure 2 As shown, a plurality of guide rollers 600 are provided on the base plate 100. The guide rollers 600 can be set at a position before the yarn enters the transmission roller 200, or at a position where the yarn leaves the transmission roller 200, or between the transmission rollers 200. By setting the guide rollers 600, the transmission direction of the yarn can be adjusted, thereby adjusting the wrap angle of the yarn passing through the transmission roller 200, and adjusting the tension of the yarn more conveniently.

[0043] Furthermore, the guide roller 600 is arranged at the position where the yarn leaves the transmission roller 200, and can also be arranged behind the tension detection roller 400, so that the tension detection roller 400 is located between the guide roller 600 and the transmission roller 200, so that the yarn can be hooked on the tension detection roller 400, maintain good contact with the tension detection roller 400, and apply pressure to the surface of the tension detection roller 400, so as to facilitate the tension detection roller 400 to detect the tension of the yarn.

[0044] In some specific embodiments of the present invention, a dipping device is further included. The dipping device includes a dipping tank 510 and a dipping roller 520 . Resin is provided in the dipping tank 510 , and the dipping roller 520 is rotatably provided in the dipping tank 510 .

[0045] For example Figure 1 and Figure 4 As shown, the dipping device includes a dipping tank 510 and a dipping roller 520. Resin is provided in the dipping tank 510. The yarn enters the dipping tank 510 and is dipped in the resin, so that the yarn has the ability to be sticky, thereby improving the performance of the webbing, reducing breakage and fading during use, and ensuring the service life.

[0046] The dipping roller 520 is rotatably disposed in the dipping tank 510 and takes the yarn out of the dipping tank 510 after the yarn completes the dipping process, thereby facilitating the yarn to enter the transmission roller 200 and providing an initial tension to the yarn.

[0047] In some specific embodiments of the present invention, the rotation axis of the dipping roller 520 is disposed on the top surface of the dipping tank 510 , and half of the roller body of the dipping roller 520 is placed in the dipping tank 510 .

[0048] For example Figure 4 As shown, the rotating shaft of the dipping roller 520 is set on the top surface of the dipping tank 510, and half of the roller body of the dipping roller 520 is placed in the dipping tank 510, which can make it more convenient to dip the yarn in glue and bring the yarn to the dipping roller 520 after dipping to be transported to the transmission roller 200.

[0049] In some specific embodiments of the present invention, the dipping device further includes a scraper 530 , which is movably disposed on the top surface of the dipping tank 510 .

[0050] For example Figure 2 and Figure 4 As shown, the dipping device further includes a scraper 530, which is movably disposed on the top surface of the dipping tank 510. The scraper 530 is movably disposed so that the distance between the scraper 530 and the dipping roller 520 can be adjusted. After the yarn is dipped in the dipping tank 510, it is driven by the dipping roller 520 and passes through the gap between the dipping roller 520 and the scraper 530, allowing the scraper 530 to scrape off excess resin on the yarn.

[0051] By adjusting the distance between the scraper blade 530 and the dipping roller 520, the resin content on the yarn can be controlled.

[0052] In some specific embodiments of the present invention, the dipping device further includes a plurality of guide rollers 540 , which are disposed on the dipping tank 510 , and the rotation axes of the guide rollers 540 are disposed on the top surface of the dipping tank 510 .

[0053] For example Figure 1 and Figure 4 As shown, the dipping device further includes a plurality of guide rollers 540, which are disposed on the dipping tank 510, and the rotation axes of the guide rollers 540 are disposed on the top surface of the dipping tank 510. The guide rollers 540 can guide the yarn so that the yarn is wound around the guide rollers 540, making it easy for the yarn to enter the dipping tank 510.

[0054] In some specific embodiments of the present invention, a plurality of yarn guide rollers 540 are provided, and the plurality of yarn guide rollers 540 are respectively provided on both sides of the dipping roller 520 .

[0055] For example Figure 4 As shown, five yarn guide rollers 540 are provided, three are provided on one side of the dipping roller 520, and two are provided on the other side, so as to facilitate the yarn transportation for dipping and transportation to the transmission roller 200.
