Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a yarn tube frame that facilitates reversal. Background Technology

[0002] In a fabric production line, yarn bobbins are typically used to support and hold yarn bobbins, ensuring smooth yarn transport during processing. To minimize the overall space occupied by the yarn bobbins, a three-dimensional structure is generally used, and the spacing between the bobbin arms is relatively small. This small spacing also makes it difficult for workers to change the inner bobbins from their workstations.

[0003] Chinese patent CN219410050U discloses a yarn bobbin holder, including a frame, a pin, and a rotating plate. The rotating plate is rotatably connected to the frame. The rotating plate has two opposing drive chains, located on its front and rear sides respectively. Each drive chain has multiple yarn spools. The rotating plate has a first through hole, and the frame has a second through hole opposite to the first through hole. The pin is used to insert into both the first and second through holes. This technical solution allows for yarn changing on both sides of the rotating plate by flipping it, offering convenient and flexible operation and saving space on the yarn bobbin holder. The pin secures the rotating plate, improving operational reliability. However, during operation, because the pin is located at the bottom of the rotating plate, manual insertion and removal of the pin is required each time the plate is operated. Furthermore, since the pin's fit with the second through hole is a shaft-hole fit, multiple manual adjustments are needed each time for accurate alignment, making the operation time-consuming and labor-intensive. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cylinder frame that can fix the rotating frame without manual adjustment of the position multiple times. It is convenient and flexible to operate, saves time and effort, reduces the labor intensity of workers, and effectively improves work efficiency.

[0005] A yarn bobbin holder for easy reversal includes a frame with at least two linearly arranged rotating frames on the frame. The two ends of each rotating frame are rotatably mounted on the frame via a rotating shaft. Multiple sleeves for mounting yarn bobbins are arranged linearly and at intervals on both sides of each rotating frame. The frame is equipped with a rotary actuator that drives the rotating shaft to rotate at an angle, thereby reversing the orientation of the rotating frames. The number of rotary actuators corresponds to the number of rotating frames. The frame is equipped with a controller that drives the rotary actuators. The rotary actuators are electrically connected to the controller. Each rotary actuator includes a mounting plate, a driving component mounted on the mounting plate, a transmission component connected to the driving component, and an output shaft that is driveably connected to the transmission component. The output shaft rotates synchronously with the rotating shaft.

[0006] Preferably, the rotary drive includes a mounting base, the output shaft is mounted on the mounting base via a bearing, the frame is provided with an assembly groove, and the mounting base is embedded in the assembly groove.

[0007] Preferably, the mounting base is provided with a limiting member that limits the rotation angle of the output shaft, and the mounting base has an clearance position, with the limiting member being radially movable within the clearance position.

[0008] Preferably, the limiting member includes a circular ring portion and a right-angled side tangent to the outer circumference of the circular ring portion, and the inner circumference of the circular ring portion is provided with a D-shaped shaft hole, and the output shaft is assembled in the D-shaped shaft hole.

[0009] Preferably, the output shaft is provided with a keyway in the axial direction, and the bottom of the keyway is chamfered.

[0010] Preferably, the mounting base is provided with a U-shaped groove, and the bottom of the transmission component is provided with a protrusion, and the transmission component slides linearly along the U-shaped groove through the protrusion.

[0011] Preferably, the output end of the output shaft is provided with a fixing member, and the rotating shaft at the upper end of the rotating frame is fixedly connected to the fixing member.

[0012] Preferably, the driving component is a hydraulic cylinder or an electric rod.

[0013] Preferably, the transmission component includes a rack portion and a gear portion that mesh with each other. The gear portion has a central hole on its shaft. The output shaft is tightly fitted with the central hole of the gear portion. The rack portion is connected to a driving component and moves linearly perpendicular to the gear axis to drive the gear to rotate. The rotation of the gear drives the output shaft to rotate.

[0014] Preferably, the output end of the drive component is provided with a limiting block, and the end of the rack portion near the drive component is provided with a limiting groove that matches the limiting block, and the limiting block is engaged in the limiting groove.

[0015] In summary, the advantages of this utility model are: In this invention, when it is necessary to change yarn on both sides of the bobbin frame, the rotation of the drive unit can simultaneously realize the rotation reversal and locking action of the bobbin frame. The bobbin frame can be fixed without manual adjustment of the position multiple times, which saves time and effort and reduces the labor intensity of workers. During the operation, the drive unit drives the transmission unit to drive the output shaft to rotate, and the output shaft drives the rotating shaft to drive synchronously. The rotating shaft rotates and thus drives the bobbin frame to rotate. The operation is convenient and flexible, saves the space occupied by the bobbin frame, and realizes automatic yarn changing on both sides of the bobbin frame, effectively improving work efficiency. Both sides of the rotating frame are equipped with yarn tube sleeves, and the rotation is reversed by an independent rotating drive. When one side of the yarn tube is used up, there is no need to stop the machine to replace it. Simply rotate it to the other side to continue feeding yarn, which significantly reduces downtime. The limiting component has a reasonable structure with the circular part tangent to the right-angled side, which plays a dual limiting role in the axial and radial directions of the output shaft. This effectively restricts the axial movement of the output shaft and reduces the radial wobble of the output shaft. At the same time, the combination of the right-angled side and the circular part enhances the overall rigidity, making it suitable for high-torque environments and improving the stability of the structure. The output shaft is equipped with a keyway, which has a self-locking characteristic. After the output shaft is installed, it can prevent axial movement of the output shaft and provide reliable axial positioning for the output shaft. The axial keyway of the output shaft extends along the length of the shaft, which can distribute the load to a larger contact area, reduce stress concentration, and the bottom of the keyway is chamfered, which can further reduce the fatigue risk of the output shaft and improve the overall strength.

[0018] To more clearly illustrate the overall concept of this utility model, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., indicating orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0019] A type of yarn tube holder that facilitates reversing, such as Figures 1 to 6 As shown, the device includes a frame 1, on which three rotating frames 2 are arranged linearly. The two ends of the rotating frames 2 are rotatably mounted on the frame 1 via rotating shafts 3. On both sides of the rotating frames 2, multiple sleeve rods 4 for mounting yarn bobbins are arranged linearly at intervals. The frame 1 is equipped with a rotary driver 5 that drives the rotating shafts 3 to rotate at an angle to change the direction of the two sides of the rotating frames 2. The number of rotary drivers 5 corresponds to the number of rotating frames 2. The frame 1 is equipped with a controller 6 that drives the rotary drivers 5. The rotary drivers 5 are electrically connected to the controller 6. The rotary driver 5 includes a mounting plate 51, a driving component 52 mounted on the mounting plate 51, a transmission component 53 connected to the driving component 52, and an output shaft 54 ​​that is transmitted to the transmission component 53. The output shaft 54 ​​rotates synchronously with the rotating shafts 3.

[0020] In this embodiment, yarn tube sleeves 4 are provided on both sides of the rotating frame 2, and are reversed by an independent rotary driver 5. When one side of the yarn tube is used up, there is no need to stop the machine to replace it; simply rotate it to the other side to continue feeding yarn, significantly reducing downtime. When it is necessary to change yarn on both sides of the frame, driving the rotary driver 5 to rotate simultaneously realizes the rotation reversal and locking action of the rotating frame 2. The rotating frame 2 can be fixed without manual adjustment multiple times, saving time and effort and reducing the labor intensity of workers. During operation, the drive component 52 drives the transmission component 53, which in turn drives the output shaft 54 ​​to rotate. The output shaft 54 ​​rotates synchronously, driving the rotating shaft 3 to rotate, which in turn drives the rotating frame 2 to rotate. The operation is convenient and flexible, saving space occupied by the frame, thereby realizing automatic yarn changing on both sides of the rotating frame 2 and effectively improving work efficiency.

[0021] Specifically, the rotary drive 5 includes a mounting base 55, and the output shaft 54 ​​is mounted on the mounting base 55 via bearings, such as... Figure 2 As shown, the frame 1 is provided with an assembly slot 11, and the mounting base 55 is embedded in the assembly slot 11. With this design, by setting the mounting base 55 and the assembly slot 11, the process of assembling the output shaft 54 ​​is simpler and more intuitive. The worker only needs to align the mounting base 55 with the assembly slot 11 and insert it, without complicated operations and additional positioning tools.

[0022] The commutative tube frame of this utility model also includes a mounting base 55, which is combined with... Figure 3 and Figure 4 As shown, the mounting base 55 is provided with a limiting member 56 to limit the rotation angle of the output shaft 54. The mounting base 55 has a clearance position 551, and the limiting member 56 is radially movably disposed within the clearance position 551. This design prevents the limiting member 56 from interfering with other components. The clearance position 551 provides the limiting member 56 with a precise installation position and movement space, ensuring that the limiting member 56 is accurately positioned in the predetermined location, thus accurately limiting the output shaft 54. Simultaneously, the clearance position 551 provides a certain degree of protection for the limiting member 56, preventing it from colliding or rubbing against other components during use.

[0023] In the reversible cylinder frame of this utility model, the limiting member 56 includes a circular part and a right-angled side tangent to the outer circumference of the circular part. The inner circumference of the circular part is provided with a D-shaped shaft hole 561, and the output shaft 54 ​​is assembled in the D-shaped shaft hole 561. With this design, the circular part is tangent to the right-angled side, which plays a dual limiting role in the axial and radial directions of the output shaft 54, effectively restricting the axial movement of the output shaft 54 ​​and reducing the radial wobble of the output shaft 54. At the same time, the combination of the right-angled side and the circular part enhances the overall rigidity, making it suitable for high torque environments and improving the stability of the structure. The annular structure of the circular part can evenly distribute the load across the entire contact surface, reducing stress concentration. The D-shaped shaft hole 561 forms a non-circular connection structure by mating the plane with the positioning tangent of the output shaft 54, achieving circumferential fixation, which can effectively prevent relative rotation between the output shaft 54 ​​and the limiting member 56 without the need for additional keys or pins, thereby avoiding the slippage problem that may occur with traditional keyed connections.

[0024] To extend the service life of the output shaft 54, a keyway is provided axially on the output shaft 54, and the bottom of the keyway is chamfered. This design, with the axial keyway extending along the length of the shaft, distributes the load over a larger contact area, reducing stress concentration. The chamfering at the bottom of the keyway further reduces the fatigue risk of the output shaft 54 ​​and improves its overall strength. The keyway has a self-locking characteristic, preventing axial movement of the output shaft 54 ​​after installation and providing reliable axial positioning.

[0025] To facilitate the assembly and disassembly of the rotating frame 2, a fixing member 57 is provided at the output end of the output shaft 54. The rotating shaft 3 at the lower end of the rotating frame 2 is detachably mounted on the frame 1 via a bearing seat, and the rotating shaft 3 at the upper end of the rotating frame 2 is fixed to the fixing member 57 with screws. With this design, the rotating shaft 3 at the upper end of the rotating frame 2 is fixed to the fixing member 57 with screws, so that the rotating shaft 3 and the fixing member 57 rotate synchronously, thereby ensuring that the rotating frame 2 and the output shaft 54 ​​rotate synchronously, while also facilitating assembly and disassembly.

[0026] In this utility model of a reversible cylinder frame, the bearing housing includes a first bearing housing, a second bearing housing, and a fixing knob. The first and second bearing housings are provided with threaded flanges, and the fixing knob has a threaded hole that matches the thread on the flange. With this design, the bearing housings are separately installed and secured by the fixing knob. When the rotating frame needs to be disassembled, simply unscrewing the fixing knob allows the bearings to be separated into two parts, enabling quick installation and disassembly of the rotating frame.

[0027] In the easily reversible bobbin frame of this utility model, the driving component 52 is a hydraulic cylinder. This design allows the hydraulic cylinder to generate significant thrust and pull, enabling it to drive heavy loads. Furthermore, the hydraulic cylinder is highly adaptable and can operate stably in harsh textile working environments such as high temperatures and dust, thus ensuring a certain degree of operational reliability.

[0028] It is understood that in other embodiments of this utility model, the driving component may also be an electric rod. This design results in high control precision and fast response speed for the electric rod, enabling very precise position control while improving equipment efficiency and production cycle time.

[0029] In the easily reversible tube frame of this utility model, such as Figure 6 As shown, the rack portion 531 has a protrusion 5312 at its bottom, and a U-shaped groove 552 is formed on the mounting plate 51. The rack portion 531 slides linearly along the U-shaped groove 552 via the protrusion 5312. This design provides a large mating area between the protrusion 5312 and the U-shaped groove, allowing for even distribution of the load borne by the rack and improving the overall load-bearing capacity. The U-shaped groove has a relatively simple structure; during installation, the protrusion 5312 of the rack portion 531 is simply inserted into the groove, facilitating installation and disassembly. Furthermore, the U-shaped groove design allows for fine-tuning of the rack portion 531 within a certain range to adapt to different installation requirements and working conditions. The U-shaped groove structure also facilitates the storage and distribution of lubricating oil, providing better lubrication of the rack and groove, reducing wear and frictional resistance. Simultaneously, it facilitates the installation of sealing devices to prevent dust, impurities, etc., from entering the groove and affecting transmission performance.

[0030] Specifically, the transmission component 53 includes a rack portion 531 and a gear portion 532 that mesh with each other, in combination Figure 3 and Figure 4As shown, the gear section 532 has a central hole 5321 on its shaft. The output shaft 54 ​​is tightly fitted to the central hole 5321 of the gear section 532. The rack section 531 is connected to the drive member 52 and moves linearly perpendicular to the gear axis to drive the gear to rotate. The rotation of the gear drives the output shaft 54 ​​to rotate. With this design, the central hole 5321 provides an accurate positioning reference for the output shaft 54. At the same time, the tight-fitting connection between the output shaft 54 ​​and the gear section 532 ensures the coaxiality of the output shaft 54 ​​and the gear, making the connection between the gear and the output shaft 54 ​​more robust, so that the output shaft 54 ​​can withstand greater torque and load.

[0031] like Figure 5 As shown, the output end of the drive unit 52 is provided with a limiting block 521, and the end of the rack part 531 near the drive unit 52 is provided with a limiting groove 5311 that is adapted to the limiting block 521. The limiting block 521 is engaged in the limiting groove 5311. With this design, the limiting block 521 can limit the movement range of the rack part 531, ensuring that the rack part 531 moves within a specified stroke. When the rack moves to the limited position, the limiting block 521 cooperates with the limiting groove 5311 to prevent it from moving further, thus avoiding overload and damage to the drive unit 52 that may occur due to exceeding the stroke.

[0032] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined by the appended claims.
