[0029] In the above embodiment, the portal frame 1 is located on both sides of the moving track 10, which ensures that the connecting rod 4 and the yarn ball fixing frame 3 can span the moving range of the trolley, providing stable and sufficient space support for the automatic conveying of the yarn ball. The portal frame 1 serves as the framework of the entire device, supporting all moving parts and defining their running tracks, enabling the yarn ball to move accurately from one station to another. The connecting rod 4 can move along the sliding track on the portal frame 1, which allows the yarn ball fixing frame 3 to move freely between the feeding station, the processing station, and the discharging station. The sliding performance of the connecting rod 4 ensures the smooth running of the yarn ball fixing frame 3, reduces vibration during movement, and improves the precision and efficiency of yarn ball processing. The yarn ball fixing frame 3 is automatically positioned between different stations on the production line by the driving of the connecting rod 4. This design ensures that the yarn ball can be accurately fed, processed, and discharged at each processing stage, reducing the need for manual operation and improving the degree of automation. The yarn ball fixing holes on the yarn ball fixing frame 3 can automatically adapt to yarn balls of different sizes, ensuring the stability and safety of the yarn ball during movement.

[0030] Specifically, as Figure 2As shown, the yarn package conveying device further comprises a conveying mechanism 2 arranged at the lower side of the yarn package fixing frame 3 to drop the yarn package on the yarn package fixing frame 3 onto the conveying mechanism 2 when the yarn package fixing frame 3 moves to the unloading station; wherein at least part of the conveying mechanism 2 is movably arranged to convey the yarn package thereon. The conveying mechanism 2 contained in the device is arranged below the yarn package fixing frame 3, so that when the yarn package fixing frame 3 reaches the unloading station, the yarn package can automatically drop onto the conveying mechanism 2, and then be conveyed to the next packaging station on the production line, reducing manual intervention and improving the automation level of the production line.

[0031] Specifically, the yarn package fixing frame 3 is slidingly connected with the connecting rod 4 to move in the vertical direction to have a first position and a second position arranged from top to bottom; wherein when the yarn package fixing frame 3 moves from the second position to the first position, the yarn package on the yarn package fixing frame 3 falls onto the conveying mechanism 2 to be conveyed by the conveying mechanism 2. The inside of the connecting rod 4 is provided with a sliding rail, and the yarn package fixing frame 3 is slidingly connected with the connecting rod 4 through the guide rail.

[0032] In the above embodiment, the second position of the yarn package fixing frame 3 is 14 cm away from the conveying mechanism 2, which ensures that the yarn package is clamped in the center position and prevents the yarn package from falling off. In addition, the first position is 30 cm away from the conveying mechanism 2, which ensures that the yarn package conveying is not limited by height.

[0033] Specifically, the conveying mechanism 2 comprises a turnover plate and a rotating shaft 7, the rotating shaft 7 is connected with the turnover plate, and the rotating shaft 7 is rotatably arranged on the connecting rod 4 to drive the turnover plate to turn over to make the conveying mechanism 2 turn over by a predetermined angle. The yarn package fixing frame 3 comprises a main frame body 32 for carrying the yarn package and a support rod 33 connected with the main frame body 32, when the yarn package fixing frame 3 is in the second position, the support rod 33 is connected with the conveying mechanism 2 to make the conveying mechanism 2 drive the yarn package fixing frame 3 to turn over. The rotating shaft 7 is designed to be rotatably arranged on the connecting rod 4, which serves as the pivot of the turnover plate and undertakes the key task of making the turnover plate turn over. When the rotating shaft 7 is driven by the linear synchronous servo motor 5, it will rotate around its axis, thereby driving the turnover plate connected therewith to turn over correspondingly. A plurality of mounting holes are provided on the rotating shaft 7 along its extension direction, and the turnover plate is mounted on the mounting holes of the rotating shaft 7 by bolts or screws and is tightly connected with the rotating shaft 7. The turnover plate is arranged inside the conveying mechanism, when the yarn package fixing frame moves to the corresponding station, the rotation of the rotating shaft 7 will drive the turnover plate to turn over to different angles. The connection between the rotating shaft 7 and the turnover plate enables the rotating shaft 7 to drive the turnover plate to turn over, thereby changing the position of the yarn package fixing frame. This design enables the yarn package fixing frame 3 to automatically adjust the angle to facilitate the conversion of the yarn package between different stations, enhancing the flexibility and adaptability of the device.

[0034] In the above embodiment, the yarn ball conveying mechanism further comprises a motor 5, and the linear synchronous servo motor 5 is arranged on the connecting rod 4, which mainly provides power for the horizontal displacement and 90° rotation of the conveying mechanism 2.

[0035] Specifically, the supporting rods 33 are multiple, and the yarn ball fixing frame 3 is provided with multiple supporting rods 33 on both sides in the horizontal direction. The side of the yarn ball fixing frame 3 close to the conveying mechanism 2 is provided with multiple supporting rods 33 on both sides along the conveying direction of the conveying mechanism 2. When the yarn ball fixing frame 3 is in the second position, the supporting rods 33 are connected with the conveying mechanism 2, so that a containing space is formed between the yarn ball fixing frame 3 and the conveying mechanism 2, so that the yarn ball on the yarn ball fixing frame 3 is fixed at a position close to the middle part.

[0036] Specifically, the conveying mechanism 2 comprises two rollers and a conveying belt. The conveying belt is arranged around the two rollers so that the rollers rotate to drive the conveying belt to rotate, and the turnover plate is installed on the inner side of the conveying belt. The two rollers are fixed on the frame of the device through bearings, and one or both of the rollers are connected with a driving device (such as a linear synchronous servo motor 5). When the driving device is started, it transmits power through a transmission assembly such as a belt or a gear to make the rollers rotate. The conveying belt is arranged around the two rollers, and when the rollers rotate, the conveying belt also rotates, thereby realizing the horizontal movement of the yarn ball. This design ensures that the yarn ball can fall smoothly from the yarn ball fixing frame to the conveying belt and be transported to the next link such as the packaging or storage area through the movement of the conveying belt.

[0037] Specifically, the connecting rod 4 is two, such as Figure 3As shown, the two ends of the rotating shaft 7 are provided with bearing parts 712, the two ends of the rotating shaft 7 are rotatably connected with the corresponding connecting rods 4 through the bearing parts 712 respectively, the rotating shaft 7 is provided with a plurality of guide teeth 713, the connecting rod 4 is provided with a mounting hole, the shaft section of the rotating shaft 7 with the guide teeth 713 extends into the mounting hole, a protrusion is arranged on the inner circumferential wall of the mounting hole, the protrusion extends into the guide teeth 713 to make the rotating shaft 7 rotate in one direction. The connecting rod 4 is two, respectively located on the two sides of the rotating shaft 7, and is rotatably connected with the two ends of the rotating shaft 7 through the bearing parts 712. This design allows the rotating shaft 7 to rotate relative to the connecting rod 4, while reducing the friction during rotation through the bearing parts 712, improving the stability and efficiency of rotation. The bearing part 712 usually includes inner and outer rings and rolling bodies, the inner and outer rings are fixedly connected with the rotating shaft 7 and the connecting rod 4 respectively, and the rolling bodies roll between the inner and outer rings to realize low-friction rotation. In order to realize the one-way rotation of the rotating shaft 7, a plurality of guide teeth 713 are arranged on the rotating shaft 7, and a protrusion is arranged on the inner circumferential wall of the mounting hole of the connecting rod 4. When the rotating shaft 7 needs to rotate, the shaft section with the guide teeth 713 of the rotating shaft 7 extends into the mounting hole of the connecting rod 4, at this time the protrusion on the inner wall of the mounting hole will extend into the gap between the guide teeth 713. This design makes the rotating shaft 7 only rotate in one direction according to the arrangement direction of the guide teeth 713, and the reverse rotation is blocked by the protrusion. The shape and arrangement of the guide teeth 713 need to match the size and position of the protrusion to realize precise one-way rotation control. In order to realize the one-way rotation of the rotating shaft 7, a plurality of guide teeth 713 are arranged on the rotating shaft 7, and a protrusion is arranged on the inner circumferential wall of the mounting hole of the connecting rod 4. When the rotating shaft 7 needs to rotate, the shaft section with the guide teeth 713 of the rotating shaft 7 extends into the mounting hole of the connecting rod 4, at this time the protrusion on the inner wall of the mounting hole will extend into the gap between the guide teeth 713. This design makes the rotating shaft 7 only rotate in one direction according to the arrangement direction of the guide teeth 713, and the reverse rotation is blocked by the protrusion. The shape and arrangement of the guide teeth 713 need to match the size and position of the protrusion to realize precise one-way rotation control.

[0038] In particular, as Figure 4As shown, the yarn ball fixing frame 3 also includes a plurality of fixing structures 31. The main frame body 32 is provided with a plurality of yarn ball fixing holes, and each yarn ball fixing hole is provided with a fixing structure 31. The fixing structure 31 includes a circular ring fixing body 311 and a plurality of elastic expansion members 312. The circular ring fixing body 311 is arranged in the corresponding yarn ball fixing hole, and the plurality of elastic expansion members 312 are arranged on the inner side of the circular ring fixing body 311 in a circumferential direction. Each elastic expansion member 312 is arranged radially and elastically to abut the yarn ball to fasten the yarn ball. The main frame body 32 is the main structure of the yarn ball fixing frame 3, and is provided with a plurality of yarn ball fixing holes with a diameter of 34 cm, which conforms to the maximum size of the glass fiber yarn ball and is used to install the fixing structure 31. The fixing structure 31 includes the circular ring fixing body 311 and the plurality of elastic expansion members 312. The circular ring fixing body 311 is arranged in the yarn ball fixing hole and serves as an internal support to provide a basic structure for the elastic expansion members 312 so that they can normally expand and contract and fix the yarn ball. The elastic expansion members 312 are arranged on the inner side of the circular ring fixing body 311 in a spaced manner. These elastic expansion members 312 are designed to be radially expandable, i.e., they can expand or contract in the radial direction of the circular ring fixing body 311, contact the outer surface of the yarn ball and apply pressure to achieve fastening of the yarn ball. The inner diameter of the fixing structure 31 corresponds to the maximum outer diameter of the yarn ball. When the yarn ball is placed in the yarn ball fixing hole, the elastic expansion members 312 will automatically expand according to the actual diameter of the yarn ball, increase the contact area with the outer surface of the yarn ball, and thus apply sufficient pressure to fasten the yarn ball. This design can adapt to yarn balls of different diameters and reduce the risk of shaking and falling of the yarn ball during movement. The automatic expansion function of the fixing structure 31 simplifies the loading and fixing process of the yarn ball and does not require additional manual operation or adjustment, thereby improving the automation degree of the entire yarn ball conveying device.

[0039] Specifically, the fixing structure 31 further comprises an elastic ring 313, each fixing structure 31 comprises two circular ring fixing bodies 311 arranged at intervals, and the elastic ring 313 is arranged between the two circular ring fixing bodies 311, and the elastic ring 313 is connected with the plurality of elastic stretchers 312 to push the plurality of elastic stretchers 312 to compress the yarn ball. The addition of the elastic ring 313 improves the stability of the yarn ball during the conveying process. The two circular ring fixing bodies 311 are arranged at intervals to form a fixing area around the yarn ball. This design provides sufficient space to accommodate the yarn ball, while also providing the necessary structural support for the arrangement of the elastic ring 313 and the elastic stretchers 312. The elastic ring 313 is arranged between the two circular ring fixing bodies 311, and its function is to enhance the stability of the yarn ball on the yarn ball fixing frame 3 through its inherent elastic force. When the yarn ball is inserted into the fixing area formed by the circular ring fixing bodies 311, the elastic ring 313 will automatically adjust its elastic force according to the size and weight of the yarn ball, ensuring that the yarn ball is tightly fixed in the fixing structure and avoiding shaking or falling off during the conveying process. The plurality of elastic stretchers 312 are connected with the elastic ring 313, and when the elastic ring 313 is pressed by the yarn ball, it will evenly distribute the elastic force to all the elastic stretchers 312. The elastic stretchers 312 can stretch and contract according to the change of the elastic force of the elastic ring 313 due to the connection with the elastic ring 313, thereby compressing the yarn ball. This design ensures that the yarn ball of any size can be effectively fixed by the fixing structure, improving the versatility and adaptability of the device.

[0040] In the above embodiment, the elastic ring 313 can be selected from spring rings, elastic sleeves, or rubber elastic rings, etc.

[0041] Specifically, the elastic extension piece 312 includes an abutting portion 312a, a first mounting portion 312b, and a second mounting portion 312c. At least part of the abutting portion 312a protrudes from the inner wall of the circular ring fixing body 311. A plurality of mounting grooves 311a extending in the radial direction are arranged on the circumference of each circular ring fixing body 311. The first mounting portion 312b and the second mounting portion 312c are arranged at one end of the abutting portion 312a in the vertical direction and are respectively connected with the mounting grooves 311a on the two circular ring fixing bodies 311 in sliding connection. The elastic ring 313 is arranged between the first mounting portion 312b and the second mounting portion 312c. At least part of the abutting portion 312a protrudes from the inner wall of the circular ring fixing body 311, which means that it directly contacts the yarn ball and provides radial support and fixation for the yarn ball. The shape and material of the abutting portion 312a need to be selected to adapt to the surface characteristics of the yarn ball and ensure that the yarn ball is not damaged during contact. The first mounting portion 312b and the second mounting portion 312c are arranged at one end of the abutting portion 312a in the vertical direction and are respectively connected with the mounting grooves on the circular ring fixing body 311 in sliding connection. This design allows the abutting portion 312a to slide in the radial direction in the mounting groove of the circular ring fixing body 311, thereby adjusting the contact pressure between the abutting portion 312a and the yarn ball and adapting to yarn balls of different diameters. The relative position between the first mounting portion 312b and the second mounting portion 312c can be adjusted by an external driving mechanism (such as a hydraulic or electric actuator), ensuring that the abutting portion 312a can automatically adjust its position when the diameter of the yarn ball changes, providing appropriate fixation force. The elastic ring 313 is arranged between the first mounting portion 312b and the second mounting portion 312c, which provides elastic support for the sliding of the abutting portion 312a, ensuring that the pressure between the abutting portion 312a and the yarn ball can be self-adaptively adjusted. The elastic properties of the elastic ring 313 allow the abutting portion 312a to automatically adjust its position when the diameter of the yarn ball changes, while maintaining uniform pressure on the yarn ball, preventing the yarn ball from moving or shaking on the fixing frame, and ensuring the stability of the yarn ball during transportation.

[0042] In the above embodiment, the glass fiber yarn ball is hung and transported by the trolley in units of 24 yarn balls. The front and back of the trolley respectively hang 12 yarn balls. When the trolley runs to the position of the conveying mechanism 2, the yarn balls on the trolley are automatically positioned and hung on the yarn ball fixing frame 3. After the yarn balls on the trolley are hung, the conveying mechanism 2 runs to the position of the winding machine to remove the inner circle yarn. After the inner circle yarn is removed, the conveying mechanism 2 automatically rotates 90° through the rotating shaft 7, switching from the vertical direction to the horizontal plane. After the yarn ball fixing frame 3 is automatically run to the position, the yarn ball is transported to the next packaging link through the conveying mechanism 2.

[0043] In some embodiments, the gantry 1 comprises two sets of linear guides 8, which are arranged at intervals along the extension direction of the moving track 10, and each set of linear guides 8 is provided with a connecting rod 4, so that the connecting rod 4 slides to drive the yarn ball holder 3 to run to the feeding station, the processing station and the discharging station in turn. The gantry 1 serves as the framework of the entire device, providing a stable basic structure, and the design of the two sets of linear guides 8 ensures that the connecting rod 4 can move smoothly on the predetermined path. The linear guides 8 are arranged in the same direction as the extension direction of the moving track 10, which means that the motion trajectory of the connecting rod 4 (and the yarn ball holder 3 connected thereto) is parallel to the moving track 10 of the trolley, so that the yarn ball holder 3 can be accurately positioned to the yarn ball on the trolley to take, place and transport the yarn ball. The linear guides 8 are also provided with HGH65HA sliders, which are R holes on the upper lock and T holes on the lower lock, and bear the function of connecting the guide and the load transfer mechanism 2. Two sliders are installed on each connecting rod 4 to prevent it from falling. By contacting the slide surface on the guide, smooth movement in the guide direction is achieved. At the same time, the slider has high load capacity and can withstand the force from the guide and the load while remaining stable. The HGH65HA slider is embedded in the linear guide 8, and the connecting rod 4 is connected to the linear guide 8 through the slider, so that the yarn ball holder can automatically run back and forth with the gantry as the support point.

[0044] When the yarn ball transfer mechanism 2 of the present application is running, first, the full-tube trolley runs to the transfer mechanism 2 position, the gantry 1 has a recognition sheet, which is positioned and started and stopped by the U-shaped switch sensing the recognition sheet, and the yarn ball stop position is ensured to be consistent with the yarn ball holder 3 position through the control program of the conveying line. The trolley automatically moves horizontally to the yarn ball holder 3 position, and the yarn ball on the trolley is embedded and clamped in the yarn ball holder 3. After the yarn ball is in place, the transfer mechanism 2 runs to the doubling equipment position, and the transfer mechanism 2 automatically rotates 30°, mainly to avoid the problem of yarn winding and breakage during doubling. After the yarn ball doubling is completed, the transfer mechanism 2 automatically resets to the initial position of 0°, and then continues to run to the inner circle conveying line position. After running to the position, 90° rotation is performed through the rotating shaft 7, and the transfer mechanism 2 is switched from the vertical position to the horizontal direction. The yarn ball holder 3 running track shows the scale size, and rises upward along the guide direction to the 30cm scale, then the transfer mechanism 2 is automatically started, and the 12 yarn balls on the plate chain are directly transported to the next packaging link in 3 times with 4 as a unit. After the yarn ball transportation is completed, the yarn ball holder 3 automatically resets to the original position.

[0045] The transfer mechanism 2 in the glass fiber yarn ball inner circle automatic doubling equipment is provided with two sections, which are automatically controlled and alternately run. If one section of the transfer mechanism 2 is not running, the other section of the transfer mechanism 2 will not run either. The two sections of the transfer mechanism 2 can be used alternately. It can realize accurate and precise doubling and removal of the yarn ball inner circle while ensuring that the production efficiency is not affected.

[0046] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:
