By installing a support mechanism, it achieves the function of improving the stability of the main body of the device, preventing deviation, and improving practicality.

[0003] Similar to the pressure roller assembly mentioned above that facilitates tensioning of the spinning yarn: although the height of the pressure roller can be quickly adjusted to adapt to the tightness of the yarn by installing an adjustment mechanism, firstly, it requires manual adjustment of the height to deal with different degrees of yarn tightness, and manual adjustment is prone to errors, resulting in over-tightening or over-feeding. Secondly, it does not have a buffer mechanism during the tensioning process, which can easily cause the spinning yarn to break due to excessive tightness.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a pressure roller device that is easy to tighten the spinning yarn, so as to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure roller device that facilitates tensioning of spinning yarn, in order to solve the problems mentioned in the background art.

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a pressure roller device for facilitating the tensioning of spinning yarn, including a frame 1, a guide roller 3 and a support mechanism 4. The upper surface of the frame 1 is provided with fixed frames 2 on both sides, which serve to support and fix the yarn. The guide roller 3 is connected to the top of the fixed frame 2 through a bearing, which facilitates the guidance of the spinning yarn. The support mechanism 4 is located in the middle of the two sets of fixed frames 2, and serves to support and adjust the yarn, thereby facilitating the adjustment of the height of the pressure roller 20 to achieve the purpose of tensioning the spinning yarn. The support mechanism 4 includes a base 5, a fixed cylinder 6 and a lifting rod 7.

[0021] The base 5 has fixed cylinders 6 bolted to both sides of its top. The fixed cylinders 6 provide support and limit. A lifting rod 7 is embedded in the top of the fixed cylinder 6. The lifting rod 7 can move up and down within the fixed cylinder 6. A movable groove 8 is provided at the center of the bottom end of the lifting rod 7. The movable groove 8 serves as a limit screw 9. A screw 9 is connected to the center of the bottom inner wall of the fixed cylinder 6 via a bearing. The screw 9 can rotate within the fixed cylinder 6. The top of the screw 9 is embedded in the movable groove 8.

[0022] The inner wall of the movable groove 8 is connected with movable threaded blocks 10. The screw 9 is threadedly connected to the movable threaded blocks 10. The rotation of the screw 9 can drive the movable threaded blocks 10 to move up and down, thereby driving the lifting rod 7 to move up and down. The middle of the base 5 is provided with a drive cavity 11. The end of the screw 9 away from the lifting rod 7 extends through the base 5 into the drive cavity 11. The outer wall of the screw 9 located in the drive cavity 11 is fitted with a worm gear 12. The screw 9 and the worm gear 12 can rotate synchronously. The screw 9 and the inner wall of the drive cavity 11 are connected by a bearing.

[0023] A worm gear 13 is connected to the middle of the drive cavity 11 via a bearing. The thread of the worm gear 13 meshes with the worm wheel 12. A forward and reverse motor 14 is provided on one side of the base 5. The output end of the forward and reverse motor 14 is connected to the worm gear 13. The forward and reverse motor 14 can drive the worm gear 13 to rotate. The rotation of the worm gear 13 drives the worm wheel 12 to rotate. The rotation of the worm wheel 12 drives the screw 9 to rotate synchronously. The rotation of the screw 9 can drive the movable threaded block 10 to move up and down, thereby driving the lifting rod 7 to move up and down, thus realizing the adjustment of the height of the pressure roller 20. The different height distribution of the pressure roller 20 and the guide roller 3 makes the yarn tighter, which facilitates spinning and avoids the yarn from being too loose and causing tangling. The top of the lifting rod 7 is connected to a limit block 15 by bolts. The limit block 15 plays a connecting and fixing role. A limit groove 16 is provided on one side of the limit block 15. The limit groove 16 plays a limiting role. A limit slider 17 is embedded in the limit groove 16. The limit slider 17 can slide up and down in the limit groove 16.

[0024] Both ends of the limiting slider 17 are connected to springs 18. The springs 18 act as a connection and contract under pressure, while also providing a certain buffer to prevent the yarn from breaking due to excessive tension from the guide roller 20. The end of the spring 18 away from the limiting slider 17 is connected to a pressure sensor 19, model LH-S05B. The pressure sensor 19 can detect the upward pressure exerted by the currently tensioned yarn on the pressure roller 20, thereby effectively calculating the yarn tension and facilitating different levels of tension adjustment for yarns of different specifications. The end of the pressure sensor 19 away from the spring 18 is connected to the inner wall of the limiting groove 16. The two sets of limiting sliders 17 are connected to the pressure roller 20 through a movable rotating shaft. The pressure roller 20, together with the guide roller 3, guides and tensions the yarn.

[0025] A controller 21 is provided on one side of the fixed cylinder 6. The controller 21 is connected to the pressure sensor 19 by a wire. The pressure sensor 19 can transmit the current tension pressure to the controller 21. The controller 21 is connected to the forward and reverse motor 14 by a wire. The controller 21 can control the forward and reverse motor 14 to rotate forward or reverse according to the current tension, thereby adjusting the height of the pressure roller 20. This makes it easier to apply a suitable tension to the yarn, so as to avoid the yarn breaking due to excessive tension or the yarn tangling due to loosening.

[0026] Working principle: When using a pressure roller device to tighten the yarn, the yarn to be tightened is passed sequentially through the outer walls of the guide roller 3 and the pressure roller 20. The forward and reverse motor 14 drives the worm gear 13 to rotate, which in turn drives the worm wheel 12 to rotate. The worm wheel 12 then drives the screw 9 to rotate synchronously. The rotation of the screw 9 drives the movable threaded block 10 to move up and down, which in turn drives the lifting rod 7 to move up and down, thereby adjusting the height of the pressure roller 20. The different height distribution of the pressure roller 20 and the guide roller 3 tightens the yarn, facilitating spinning and preventing the yarn from becoming too loose and tangling. The spring 18 acts as a connector and is compressed. The tensioning mechanism provides a buffering effect, preventing excessive tension on the guide roller 20 that could lead to yarn breakage. The pressure sensor 19 detects the upward pressure exerted by the currently tensioned yarn on the pressure roller 20, thus effectively calculating the yarn tension. This allows for adjustments to the tension of yarns of different specifications. The pressure sensor 19 transmits the current tensioning pressure to the controller 21, which controls the forward or reverse rotation of the forward or reverse motor 14 to adjust the height of the pressure roller 20. This ensures a suitable tension for the yarn, preventing breakage due to excessive tension or tangling due to loose yarn.
