Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a spinning unit structure. Background Technology

[0002] The spinning unit in a spinning machine is the core component of the spinning equipment, responsible for processing fibers (such as cotton, wool, and synthetic fibers) into continuous yarn. Different types of spinning machines (such as ring spinning, rotor spinning, and air-jet spinning) have different structures and working principles for their spinning units, but their basic functions all revolve around fiber drafting, twisting, and winding.

[0003] A relevant reference is Chinese utility model patent CN209052191U, which discloses a spinning and winding unit assembly structure. Multiple spinning bobbins on this assembly are mounted on a unit support. The drive shaft at the bottom of the spinning bobbins passes through a bearing in a receiving groove and extends below the base plate. The driven shaft at the top of the spinning bobbins is movably fixed by a fixing plate, which is equipped with pins for fixing the driven shaft. Replacing the spinning bobbins only requires opening the fixing plate, making it very convenient and quick. The drive shaft of the spinning bobbins is connected to a rotating wheel, which is mounted on a drive support plate. Auxiliary wheels are hinged to the drive support plate between the multiple spinning bobbins, and a drive wheel is also hinged to the drive support plate. A transmission belt crosses between the multiple rotating wheels, auxiliary wheels, and drive wheels. A drive motor is connected downwards to the drive wheel. The drive motor drives the multiple spinning bobbins to rotate together via the drive wheel. This winding unit assembly can be driven by a single drive motor, effectively reducing the overall size of the spinning machine during installation.

[0004] The above-mentioned spinning and winding unit structure restricts the position of the spinning bobbin by using a fixing plate. This method requires opening the fixing plate during the replacement of the spinning bobbin, which is cumbersome. In addition, during the rotation of the spinning bobbin, insufficient friction may cause the shaft to spin freely. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spinning unit structure that solves the problems of cumbersome spinning bobbin replacement operations and the inability to effectively drive the spinning bobbin to rotate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A spinning unit structure includes a connecting frame, and a winding mechanism is disposed above the connecting frame.

[0007] A drive component, located above the connecting frame, is used to drive the limit component to rotate;

[0008] The limiting component includes a limiting frame disposed above the driving component. A drive motor is fixedly installed at the top of the limiting frame. A lead screw is fixedly installed below the rotating shaft of the drive motor. A transmission frame is movably installed on the outer side of the lead screw. Connecting rods are movably installed on both sides of the transmission frame. A connecting rod is movably installed at the top of the connecting rod. A winding drum is inserted and installed on the outer side of the limiting frame.

[0009] Preferably, the winding mechanism includes a drive motor fixedly installed inside the connecting frame, a transmission shaft inserted at the top of the drive motor shaft, a bearing inserted at the outside of the transmission shaft, a support plate fixedly installed at the top of the transmission shaft, a limit rod movably installed at the outside of the support plate, and a counterweight fixedly installed at the lower end of the limit rod.

[0010] Preferably, the top of the connecting frame is provided with an opening structure with a diameter matching the bearing, and the rotating shaft of the drive motor is fixedly connected to the bottom end of the transmission shaft by means of insertion, and the transmission shaft is rotatably connected to the connecting frame through the bearing.

[0011] Preferably, the support plate is fixedly connected to the drive shaft by bolts, the limiting rod has a "Z" shaped structure, and the limiting rod is rotatably connected to the support plate by the columnar structures at both ends.

[0012] Preferably, the diameter of the opening structure at the top of the limiting frame is larger than the diameter of the lead screw thread structure, the shaft of the transmission motor is fixedly connected to the lead screw, and the transmission frame and the limiting frame are slidably connected.

[0013] Preferably, the bottom end of the connecting rod is rotatably connected to the transmission frame, the top end is rotatably connected to the connecting rod, the top end of the connecting rod is rotatably connected to the limiting frame, and the bottom end of the winding drum is provided with a disc-shaped protrusion.

[0014] Beneficial effects

[0015] This invention provides a spinning unit structure. Compared with the prior art, it has the following advantages:

[0016] (1) In this spinning unit structure, the top end of the lead screw is fixedly connected to the shaft of the drive motor through the setting of the drive motor. The drive motor can drive the lead screw to rotate. Since the drive frame is fitted inside the limit frame, the rotation angle is limited by the limit frame. When the lead screw rotates, the drive frame installed on the outside of the lead screw through the threaded structure can generate vertical displacement and drive the connecting rods on both sides to move. When the connecting rod moves upward, it will push the connecting rod from the inside to the outside to rotate outward with the top columnar structure axis as the reference, so that the outer end of the connecting rod contacts the inner wall of the winding drum, thereby limiting the position of the winding drum. When the connecting rod moves downward, it will drive the connecting rod to rotate from the outside to the inside, so that the connecting rod can be retracted for easy replacement of the winding drum.

[0017] (2) In this spinning unit structure, the counterweight is fixed to the bottom end of the limiting rod. The limiting rod is movably installed on the outside of the support plate and forms a rotating connection with the support plate. When the drive motor drives the support plate to rotate through the transmission shaft, the limiting rod on the outside of the support plate will rotate towards the center of rotation under the action of the centrifugal force of the counterweight. This causes the top of the limiting rod to contact the top surface of the disc-shaped protrusion at the bottom of the winding drum when the support plate rotates, and presses the winding drum down, thereby increasing the friction between the winding drum and the support plate and avoiding the situation of free rotation.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a spinning unit structure, including a connecting frame 1, and a winding mechanism 2 is arranged above the connecting frame 1.

[0025] The drive assembly 21 is located above the connecting frame 1 and is used to drive the limiting assembly 22 to rotate. The winding mechanism 2 includes a drive motor 211 fixedly installed inside the connecting frame 1. A transmission shaft 212 is inserted and installed at the top of the drive motor 211 shaft. A bearing 213 is inserted and installed on the outside of the transmission shaft 212. A support plate 214 is fixedly installed at the top of the transmission shaft 212. A limiting rod 215 is movably installed on the outside of the support plate 214. A counterweight 216 is fixedly installed at the lower end of the limiting rod 215. The top of the connecting frame 1 is provided with an opening structure with a diameter matching that of the bearing 213. The drive motor 211 shaft is fixedly connected to the bottom end of the transmission shaft 212 by insertion. The transmission shaft 212 is rotatably connected to the connecting frame 1 through the bearing 213. The support plate 214 is fixedly connected to the transmission shaft 212 by bolts. The limiting rod 215 has a "Z" shaped structure. The limiting rod 215 is rotatably connected to the support plate 214 through the columnar structures at both ends.

[0026] Specifically, the connecting frame 1 can restrict the position of the drive motor 211. The drive motor 211 can drive the support plate 214 to rotate through the transmission shaft 212. The bearing 213 can reduce the friction between the transmission shaft 212 and the connecting frame 1 when the transmission shaft 212 rotates. When the support plate 214 rotates, the outer limiting rod 215 will rotate towards the center of rotation under the action of the centrifugal force of the counterweight 216. This will cause the top of the limiting rod 215 to contact the top surface of the disc-shaped protrusion at the bottom of the winding drum 227 when the support plate 214 rotates, and press the winding drum 227 down, thereby increasing the friction between the winding drum 227 and the support plate 214 and preventing the winding drum from spinning freely.

[0027] The limiting component 22 includes a limiting frame 221 disposed above the drive component 21. A drive motor 222 is fixedly mounted on the top of the limiting frame 221. A lead screw 223 is fixedly mounted below the shaft of the drive motor 222. A transmission frame 224 is movably mounted on the outer side of the lead screw 223. Connecting rods 225 are movably mounted on both sides of the transmission frame 224. A connecting rod 226 is movably mounted on the top of the connecting rods 225. A winding spool 227 is inserted and installed on the outer side of the limiting frame 221. The diameter of the opening structure at the top of the limiting frame 221 is larger than the diameter of the thread structure of the lead screw 223. The shaft of the drive motor 222 is fixedly connected to the lead screw 223. The transmission frame 224 is slidably connected to the limiting frame 221. The bottom end of the connecting rod 225 is rotatably connected to the transmission frame 224, and the top end is rotatably connected to the connecting rod 226. The top end of the connecting rod 226 is rotatably connected to the limiting frame 221. The bottom end of the winding drum 227 is provided with a disc-shaped protrusion.

[0028] Specifically, the limiting frame 221 restricts the movement direction of the transmission frame 224 and the position of the top end of the connecting rod 226. The top end of the lead screw 223 is fixedly connected to the shaft of the transmission motor 222, allowing the drive motor 222 to rotate the lead screw 223. Since the transmission frame 224 is fitted inside the limiting frame 221, its rotation angle is limited by the limiting frame 221. When the lead screw 223 rotates, the transmission frame 224, which is installed on the outside of the lead screw 223 via a threaded structure, can generate vertical displacement, thereby driving the connecting rods on both sides... When the connecting rod 225 moves upward, it will push the connecting rod 226 outward from the inside, rotating it outward around the axis of the top cylindrical structure, so that the outer end of the connecting rod 226 contacts the inner wall of the winding drum 227, thereby restricting the position of the winding drum 227. When the connecting rod 225 moves downward, it will drive the connecting rod 226 to rotate inward from the outside, so that the connecting rod 226 can be retracted to facilitate the replacement of the winding drum 227. At the same time, all contents not described in detail in this specification are prior art known to those skilled in the art.

[0029] During operation, the top end of the lead screw 223 is fixedly connected to the shaft of the drive motor 222, allowing the drive motor 222 to drive the lead screw 223 to rotate. Since the transmission frame 224 is fitted inside the limiting frame 221, the rotation angle is limited by the limiting frame 221. When the lead screw 223 rotates, the transmission frame 224, which is installed on the outside of the lead screw 223 via a threaded structure, undergoes vertical displacement, driving the connecting rods 225 on both sides to move. When the connecting rods 225 move upwards, they will push the connecting rod 226 outwards from the inside, rotating it around the axis of the top cylindrical structure, causing the outer end of the connecting rod 226 to contact the inner wall of the winding drum 227, thus limiting the position of the winding drum 227. During the downward movement of the connecting rods 225, they will... The moving link 226 rotates from the outside to the inside, causing the link 226 to retract, facilitating the replacement of the winding drum 227. The counterweight 216 is fixed to the bottom end of the limiting rod 215, which is movably mounted on the outside of the support plate 214 and forms a rotatable connection with the support plate 214. When the drive motor 211 drives the support plate 214 to rotate through the transmission shaft 212, the limiting rod 215 on the outside of the support plate 214 will rotate towards the center of rotation under the action of the centrifugal force of the counterweight 216. This causes the top end of the limiting rod 215 to contact the top surface of the disc-shaped protrusion at the bottom end of the winding drum 227 when the support plate 214 rotates, and presses the winding drum 227 downward, thereby increasing the friction between the winding drum 227 and the support plate 214 and preventing it from spinning freely.
