Description

A tensioning device for yarn winding Technical Field

[0001] This utility model relates to the field of yarn winding technology, and in particular to a tensioning device for yarn winding. Background Technology

[0002] Yarn winding is a crucial step in the textile production process, aiming to collect yarn from the spinning machine or textile machine into a spool. During winding, a tensioning mechanism is typically used to ensure stable yarn tension, and appropriate control methods are employed to keep the spool neat and compact. The smooth execution of this process is vital to subsequent textile processes and product quality. Currently, many yarn winding devices use traditional tensioning mechanisms that rely on pressing devices to maintain yarn tension. However, existing tensioning mechanisms typically only provide a fixed pressure. During winding, as the spool diameter increases, the yarn gradually lifts, causing the pressure applied by the tensioning mechanism to continuously increase. This situation can easily lead to yarn breakage. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the tensioning device cannot adjust the pressure applied to the yarn in real time, and to propose a yarn winding tensioning device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a tensioning device for yarn winding, including a frame, an adjusting rod rotatably connected to one side of the front end of the frame, a connecting frame fixedly connected to the outer wall of the adjusting rod, an extension rod slidably inserted into one end of the connecting frame, a fixing frame fixedly connected to one end of the extension rod, a tensioning roller rotatably connected inside the fixing frame, a plurality of support springs fixedly connected between the connecting frame and the extension rod, and a silicone sheet adhered to the outer wall of the tensioning roller.

[0006] Preferably, a servo motor is fixedly connected to one side of the rear end face of the frame, and the output end of the servo motor passes through the frame and is fixedly connected to the adjusting rod.

[0007] Preferably, a limiting groove is provided on the other side of the front end face of the frame, a connecting rod is fixedly connected inside the limiting groove, a moving block is slidably sleeved on the outer wall of the connecting rod, a fixing spring is fixedly connected to the upper end face of the moving block, an extrusion strip is fixedly connected to the outer wall of the moving block, and a cotton strip is fixedly connected to the lower end face of the extrusion strip.

[0008] Preferably, a rotating roller is rotatably connected to the lower side of the other side of the front end face of the frame, and a winding sleeve is engaged with the outer wall of the rotating roller.

[0009] The yarn winding tensioning device proposed in this utility model has the following advantages:

[0010] 1. This utility model achieves yarn tensioning during winding by adjusting the rotation angle of the tension roller. Multiple support springs are fixedly connected between the connecting frame and the extension rod. The support springs provide good support. As the yarn gradually increases in size during winding, the tension roller is lifted by the yarn. The movement of the tension roller causes one end of the extension rod to enter the interior of the connecting frame. The multiple support springs contract, and the tension roller automatically adjusts its position as the yarn is lifted, maintaining effective pressure on the yarn and preventing the yarn from breaking due to excessive pressure on the tension roller during winding.

[0011] 2. This utility model provides an extrusion strip and a cotton strip above the winding sleeve. During the winding process, the cotton strip remains in close contact with the yarn spool, which prevents the yarn spool from unraveling and maintains its compactness. In addition, the cotton strip cleans the surface of the yarn spool, ensuring the cleanliness and quality of the yarn during winding. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1

[0018] Referring to Figures 1 and 3, a yarn winding tensioning device includes a frame 1. An adjusting rod 2 is rotatably connected to one side of the front end of the frame 1. A connecting frame 3 is fixedly connected to the outer wall of the adjusting rod 2. An extension rod 4 is slidably inserted into one end of the connecting frame 3. A fixing frame 5 is fixedly connected to one end of the extension rod 4. A tensioning roller 6 is rotatably connected inside the fixing frame 5. Multiple support springs 13 are fixedly connected between the connecting frame 3 and the extension rod 4. When the multiple support springs 13 contract, the tensioning roller 6 automatically adjusts its position as the yarn is lifted, maintaining effective pressure on the yarn and preventing the yarn from breaking due to excessive pressure on the tensioning roller 6 during winding. A silicone sheet 14 is attached to the outer wall of the tensioning roller 6, which provides positive friction, making the yarn more stable during movement.

[0019] Referring to Figures 2 and 3, a servo motor 17 is fixedly connected to one side of the rear end face of the frame 1. The output end of the servo motor 17 passes through the frame 1 and is fixedly connected to the adjusting rod 2. A rotating roller 15 is rotatably connected to the lower side of the other side of the front end face of the frame 1. A winding sleeve 16 is snapped onto the outer wall of the rotating roller 15. The installation is simple and the disassembly is convenient.

[0020] Working principle: When the yarn needs to be wound, one end of the yarn will be wrapped around the winding sleeve 16. The motor works, and the output end of the motor rotates, driving the rotating roller 15 to rotate. The rotating roller 15 rotates, driving the winding sleeve 16 to wind up the yarn. The servo motor 17 is started, and the servo motor 17 works, driving the output end to rotate. The output end rotates, driving the adjusting rod 2 to rotate. The adjusting rod 2 rotates, causing the connecting frame 3 and the extension rod 4 to rotate synchronously. The extension rod 4 rotates, causing the fixing frame 5 to rotate. The fixing frame 5 rotates, causing the silicone sheet 14 on the tension roller 6 to press the wound yarn until the yarn is taut. The servo motor 17 is turned off. During the winding process, the diameter of the yarn ball on the tension roller 6 will become larger and larger, so that the yarn will be gradually lifted during winding. During the lifting process, the tension roller 6 will be lifted by the yarn. The tension roller 6 moves, causing one end of the extension rod 4 to enter the interior of the connecting frame 3. Multiple support springs 13 contract to prevent the yarn from breaking under the excessive pressure of the tension roller 6. After the winding is completed, the motor is turned off.

[0021] Example 2

[0022] Referring to Figures 1 and 2, as another preferred embodiment of this utility model, the difference from Embodiment 1 is that a limiting groove 7 is provided on the other side of the front end face of the frame 1. A connecting rod 8 is fixedly connected inside the limiting groove 7. A moving block 9 is slidably sleeved on the outer wall of the connecting rod 8. A fixing spring 10 is fixedly connected to the upper end face of the moving block 9. An extrusion strip 11 is fixedly connected to the outer wall of the moving block 9. A cotton strip 12 is fixedly connected to the lower end face of the extrusion strip 11. During the winding process of the winding sleeve 16, the cotton strip 12 is always in close contact with the yarn ball. On the one hand, it can prevent the yarn ball from unraveling and maintain the compactness of the yarn ball. On the other hand, the cotton strip 12 plays a role in cleaning dust from the surface of the yarn ball, ensuring the cleanliness and quality of the yarn during winding.

[0023] Working principle: Since the cotton strip 12 on the extrusion bar 11 is in contact with the winding sleeve 16, the cotton strip 12 is always in close contact with the yarn ball during the winding sleeve 16 winding the yarn. On the one hand, it can prevent the yarn ball from unraveling, and on the other hand, the cotton strip 12 can clean the dust on the surface of the yarn ball. As the size of the yarn ball continues to increase, the extrusion bar 11 moves upward. The movement of the extrusion bar 11 drives the moving block 9 to move, and the fixing spring 10 retracts. After the winding is completed, the winding sleeve 16 can be removed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
