Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a single-spindle winding machine that facilitates bobbin changing. Background Technology

[0002] In the textile industry's production process, the winding machine, as a key pre-processing equipment, undertakes the core task of rewinding semi-finished products such as yarn tubes and skeins produced in the spinning workshop into winding bobbins with uniform structure and appropriate capacity. Its operating efficiency and ease of operation directly affect the production rhythm of subsequent weaving, dyeing, and knitting processes. It is an important link to ensure the continuous and efficient operation of the textile production line. With the textile industry's increasing demand for product diversification and small-batch production, single-spindle winding machines have been widely used in small and medium-sized textile enterprises and special yarn processing scenarios due to their flexible production scheduling advantages. The requirements for their ease of bobbin changing, adaptability, and stability are also increasing.

[0003] Existing single-spindle winding machines typically consist of a frame, drive roller, bobbin fixing mechanism, yarn guiding assembly, and control unit. Their operation is roughly as follows: the motor drives the roller to rotate; the bobbin fixing mechanism positions the winding bobbin; and the friction between the roller and the bobbin drives the bobbin to rotate synchronously. The yarn is guided by the yarn wheel and guiding assembly and evenly wound onto the surface of the winding bobbin. Once a roll of yarn is wound, the equipment must be stopped, the bobbin fixing mechanism manually loosened, the full bobbin removed, the empty bobbin installed back into the fixing mechanism and re-secured, and then the equipment restarted to resume production.

[0004] In practical applications, existing single-spindle winding machines still have some room for optimization: First, the adaptability of the bobbin fixing mechanism is limited. When faced with winding bobbins of different inner diameters, it is often necessary to replace special clamps or make complex mechanical adjustments, which is cumbersome and time-consuming, making it difficult to quickly respond to diverse production needs; Second, during bobbin changing, there are many steps involved in fixing and loosening the bobbin, which requires a high level of operator proficiency, and each bobbin change takes a long time. Frequent bobbin changes can easily lead to a decrease in production efficiency. Therefore, we propose a single-spindle winding machine that facilitates bobbin changing. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-8 This embodiment provides a technical solution: a single-spindle winding machine that facilitates bobbin changing, including a frame 1, an L-shaped rod 3 rotatably connected to the right inner wall of the frame 1, the L-shaped rod 3 being rotatably connected to the right inner wall of the frame 1 via a rotating shaft, a counterweight 4 fixedly connected to the lower end of the L-shaped rod 3, a roller 5 rotatably connected to the upper side between the left and right inner walls of the frame 1, a control switch group 14 installed on the left side of the frame 1, the input end of the control switch group 14 being electrically connected to an external power source, a motor 6 installed on the right side of the frame 1, the output shaft of the motor 6 being fixedly connected to the center of the right end face of the roller 5, the motor 6 being started by the control switch group 14, the output shaft of the motor 6 directly driving the roller 5 inside the frame 1 to rotate, providing core power for winding, a yarn wheel 13 rotatably connected to the upper end of the front side of the frame 1, and also including a bobbin socket 2;

[0028] Cylindrical socket 2: It includes a cylinder 201, a sliding hole 202, a sliding cylinder 204, a sliding rod 205, an arc-shaped inner support plate 206, a cylinder 216, a circular piece 219, and a circular hole 220. The cylinder 201 is rotatably connected to the upper left side of the L-shaped rod 3 and cooperates with the roller 5. The sliding cylinders 204 are slidably connected to the sliding holes 202 provided in the cylinder wall of the cylinder 201. The sliding rods 205 are slidably connected inside each of the sliding cylinders 204. An arc-shaped inner support plate 206 is fixedly connected between each two adjacent sliding rods 205. A scale groove can be provided on the outer arc surface of the two right sliding rods 205. The sliding distance of the slide rod 205 inside the slide cylinder 204 is determined by the scale groove. Since the sliding distance of the slide cylinder 204 inside the sliding hole 202 is constant, changing the position of the slide rod 205 inside the slide cylinder 204 can adapt to yarn bobbins with different inner diameters. The circular piece 219 is fixedly connected to the left side of the inner arc surface of the cylinder 201. The cylinder 216 is slidably connected to the inside of the circular hole 220 in the middle of the circular piece 219 and works with the two slide rods 205 on the left side. The inner arc surface of the circular hole 220 is provided with a sliding opening, and the outer arc surface of the cylinder 216 is provided with a protrusion. The protrusion is slidably connected to the sliding opening to ensure that the cylinder 216 does not rotate.

[0029] The bobbin socket 2 also includes a fixing frame 203, a connecting rod 217, and a circular plate 218. The fixing frames 203 are respectively disposed inside the cylinder 201. The sides of the fixing frames 203 away from the center of the cylinder 201 are fixedly connected to the sides of the adjacent sliding rods 205 near the center of the cylinder 201. The connecting rods 217 are rotatably connected to the right ends of the cylinder 216. The right ends of the connecting rods 217 are rotatably connected to the U-shaped seats on the left ends of the horizontally adjacent fixing frames 203. The circular plate 218 is rotatably connected to the left end of the cylinder 216 and threadedly connected to the inner arc surface of the left end of the cylinder 201. The worker holds the winding bobbin. The cylinder 218 on the left side of the rotating tube socket 2 is fitted onto the outer arc of the two arc-shaped inner support plates 206. Because the circular plate 218 is threadedly connected to the inner arc surface of the left end of the cylinder 201, and because the sliding opening of the inner arc surface of the circular hole 220 slides with the protrusion of the outer arc surface of the cylinder 216, the circular plate 218 will push the cylinder 216 to slide axially along the circular hole 220 of the circular plate 219 when it rotates. The cylinder 216 drives the fixing frame 203 to move radially through the connecting rod 217. The fixing frame 203 drives the sliding cylinder 204 to extend out from the sliding hole 202, thereby driving the arc-shaped inner support plate 206 to open the interior of the inner support winding tube.

[0030] The tube socket 2 also includes inclined grooves 207, drive columns 208, upright plates 211, drive plates 212, rib grooves 213, and ribs 214. Inclined grooves 207 are respectively opened at one end of the two left-side sliding rods 205 located inside the cylinder 201. Upright plates 211 are respectively fixedly connected between the upper and lower inner walls of the two fixed brackets 203. Rib grooves 213 are opened in the middle of each upright plate 211. Rib 214 are fixedly connected to the front side of each drive plate 212, and each rib 214 is slidably connected to the adjacent rib groove 213 on the front side. Drive columns 208 are respectively fixedly connected to the rear side of each drive plate 212, and the rear ends of each drive column 208 are... Inside the adjacent inclined groove 207 on the rear side, the drive plate 212 moves, and the drive column 208 on its back slides along the inclined groove 207 of the left slide rod 205. Through the guiding action of the inclined surface of the inclined groove 207, the extension length of the slide rod 205 inside the slide cylinder 204 is pushed, so that the arc-shaped inner support plate 206 moves. Since the diameter of the cylinder 201 and the sliding distance of the slide cylinder 204 are fixed, in order to adapt to the inner diameter of the yarn tube, the extension length of the slide rod 205 inside the slide cylinder 204 is the diameter A of the cylinder 201 + the sliding distance B / 2 of the slide cylinder 204. The scale groove on the outer arc surface of the right slide rod 205 can help to accurately adjust the extension amount.

[0031] The tube socket 2 also includes a guide groove 209, a mounting plate 210, and a screw 215. The guide groove 209 is respectively opened at the upper and lower ends of the circular piece 219. The mounting plate 210 is slidably connected inside the guide groove 209. The screw 215 is threadedly connected to the middle of the mounting plate 210. The right end of the screw 215 is rotatably connected to the middle of the left side of the adjacent drive piece 212 on the right side. A turntable can be rotatably connected to the left end of the two screws 215. A bellows is set between the right side of the turntable and the left side of the mounting plate 210, and between the right side of the mounting plate 210 and the left side of the drive piece 212, so that the threaded groove of the screw 215 is located inside the bellows, providing external protection for the threaded part of the screw 215. When the screw 215 is rotated, the screw 215 pushes the drive piece 212 to move. The drive piece 212 moves axially through the sliding guide of the rib groove 213 of the vertical plate 211 via the rib 214.

[0032] A groove 7 is provided on the upper end of the front side wall of the frame 1. A guide frame 8 is slidably connected inside the groove 7. The upper end of the guide frame 8 is a circular wire ring, and the lower end of the guide frame 8 is a strip-shaped opening 9. A cover 15 is installed on the upper end of the front inner wall of the frame 1. A stainless steel rod 10 is rotatably connected to the rear inner wall of the cover 15 via a rotating shaft. A pin 11 is fixedly connected to the lower end of the front side of the stainless steel rod 10. The front end of the pin 11 is located inside the strip-shaped opening 9. A motor 12 is installed on the rear side of the cover 15. The output shaft of the motor 12 is fixedly connected to the center of the rear end face of the rotating shaft. The input end of the motor 12 is electrically connected to an external power source. The employee guides one end of the external yarn from the warp yarn wheel 13 through the circular wire ring on the upper end of the guide frame 8 and winds it onto the winding bobbin. The winding bobbin is fixed to the cylinder 201 of the bobbin socket 2. The counterweight 4 at the lower end of the L-shaped rod 3 ensures that the cylinder 201 is always in close contact with the surface of the rotating roller 5 through gravity. During rotation, friction drives the cylinder 201 and the winding bobbin to rotate synchronously, achieving yarn winding. At the same time, the motor 12 is started by the control switch group 14. The output shaft of the motor 12 drives the rotating shaft and stainless steel rod 10 inside the machine cover 15 to rotate. The pin 11 at the lower end of the stainless steel rod 10 is embedded in the slot 9 of the guide frame 8. When the stainless steel rod 10 rotates, the pin 11, through the limiting action of the slot 9, drives the guide frame 8 to move back and forth in a straight line along the slide groove 7 of the machine frame 1. As the guide frame 8 slides back and forth, the yarn is cross-wound onto the winding bobbin, avoiding the yarn from overlapping and piling up in the same position. After winding for a certain period of time, the motor 6 and the motor 12 are turned off to stop the winding operation. The circular plate 218 is rotated in the opposite direction, causing the cylinder 216 to move to the left. The connecting rod 217 pulls the fixing frame 203 and the sliding rod 205 to retract, and the arc-shaped inner support plate 206 separates from the inner wall of the winding bobbin. The inner support fixing is released, and the winding bobbin fully wrapped with yarn can be easily taken out.

[0033] The working principle of the single-spindle winding machine with easy bobbin changing provided by this utility model is as follows: According to the inner diameter of the winding bobbin, the screw 215 is rotated, and the screw 215 pushes the drive plate 212 to move. The drive plate 212 is guided by the rib groove 213 of the upright plate 211 through the rib 214. The drive column 208 on its back slides along the inclined groove 207 of the left slide rod 205. Through the inclined surface guidance of the inclined groove 207, the extension length of the slide rod 205 inside the slide cylinder 204 is pushed, so that the arc-shaped inner support plate 206 moves. Since the diameter of the cylinder 201 and the sliding distance of the slide cylinder 204 are fixed, in order to adapt to the inner diameter of the yarn bobbin, the extension length of the slide rod 205 inside the slide cylinder 204 is the diameter A of the cylinder 201 + the sliding distance B / 2 of the slide cylinder 204. The right slide rod 205... The graduated groove on the outer arc surface of 05 can assist in precise adjustment of the extension amount. Then, the worker holds the winding bobbin and places it on the outer arc of the two arc-shaped inner support plates 206. The circular plate 218 on the left side of the bobbin socket 2 is rotated. Because the circular plate 218 is threaded to the inner arc surface of the left end of the cylinder 201, and because the sliding mouth of the inner arc surface of the circular hole 220 slides with the protrusion of the outer arc surface of the cylinder 216, the rotation of the circular plate 218 will push the cylinder 216 to slide axially along the circular hole 220 of the circular piece 219. The cylinder 216 drives the fixing frame 203 to move radially through the connecting rod 217. The fixing frame 203 drives the sliding cylinder 204 to extend from the sliding hole 202, thereby driving the arc-shaped inner support plate 206 to open the interior of the inner support winding bobbin. During this process, as the fixing frame 203 moves, the mounting plate 210 moves along the circular piece 219. The guide groove 209 is limited to slide, and then the employee guides one end of the external yarn from the warp yarn wheel 13 through the annular wire ring at the upper end of the guide frame 8 and winds it onto the winding bobbin. Then, the motor 6 is started by the control switch group 14. The output shaft of the motor 6 directly drives the roller 5 inside the frame 1 to rotate, providing the core power for winding. The winding bobbin is fixed on the cylinder 201 of the bobbin socket 2. The counterweight 4 at the lower end of the L-shaped rod 3 ensures that the cylinder 201 is always in close contact with the surface of the rotating roller 5 through gravity. When the roller 5 rotates, the friction drives the cylinder 201 and the winding bobbin to rotate synchronously, realizing yarn winding. At the same time, the motor 12 is started by the control switch group 14. The output shaft of the motor 12 drives the rotating shaft and stainless steel rod 10 inside the machine cover 15 to rotate. The pin 11 at the lower end of the stainless steel rod 10 is embedded in the slot 9 of the guide frame 8. When the stainless steel rod 10 rotates, the pin 11, through the limiting action of the slot 9, drives the guide frame 8 to reciprocate linearly along the slide groove 7 of the frame 1. As the guide frame 8 slides back and forth, the yarn is cross-wound onto the winding bobbin, preventing the yarn from overlapping and piling up in the same position. During the winding process, as more and more yarn is wound, the diameter of the bobbin increases, and the bobbin generates a reverse thrust on the roller 5, causing the L-shaped rod 3 to rotate. After a certain winding time, the motor 6 and the motor 12 are turned off, stopping the winding operation. The circular plate 218 is rotated in the opposite direction, causing the cylinder 216 to move to the left. The connecting rod 217 pulls the fixed frame 203 and the sliding rod 205 to retract, and the arc-shaped inner support plate 206 separates from the inner wall of the winding bobbin.Release the inner support to easily remove the fully wound yarn bobbin.

[0034] It is worth noting that the motor 6 disclosed in the above embodiments can be model Y90L-6, the motor 12 can be model 6IK180RGN, and the control switch group 14 is provided with control buttons that correspond one-to-one with the motor 6 and the motor 12 and are used to control their switching.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
