Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a multi-functional warping frame. 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 shaft, 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 bobbins. The rotating plate has a first through hole, and the frame has a second through hole opposite to the first through hole. The pin shaft is inserted into both the first and second through holes. This technical solution achieves yarn changing on both sides of the rotating plate by flipping it, making operation convenient and flexible, saving space on the yarn bobbin holder, and improving operational reliability by fixing the rotating plate with the pin shaft.

[0004] However, during operation, since the pin is located at the bottom of the rotating plate, it is necessary to bend over and manually insert or remove the pin each time the rotating plate is operated. Furthermore, due to the fit between the pin and the second through hole, it is necessary to manually fine-tune the position multiple times each time to achieve alignment, making the operation time-consuming and laborious. Summary of the Invention

[0005] 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.

[0006] A multi-functional warping frame includes a frame, which includes a frame portion arranged linearly along the longitudinal direction of a coordinate axis and a crossbeam connecting the frame portion laterally along the coordinate axis. The frame portion includes a first frame and a second frame mirror-arranged on the left and right sides of the crossbeam along the central axis of the crossbeam. The first frame is hinged to the crossbeam, and the second frame is movably mounted on the crossbeam via an adjustment mechanism. The first frame is provided with a yarn bobbin unit, and the second frame is provided with a yarn splitting unit and a fuzz removal unit. The fuzz removal unit and the yarn splitting unit are alternately arranged on both sides of the second frame.

[0007] Preferably, the adjustment mechanism includes a rack fixedly mounted on a crossbeam, a cylindrical gear meshing with the tooth surface of the rack, and a bevel gear pair rigidly connected to the shaft end of the cylindrical gear. The bevel gear pair is provided with an input interface, and an operating lever is detachably mounted on the input interface.

[0008] Preferably, the bevel gear pair includes a first bevel gear and a second bevel gear, the axes of the first bevel gear and the second bevel gear intersect at a 90° angle, the shaft end of the first bevel gear is rigidly connected to the shaft end of the cylindrical gear, and the input interface is located at the shaft end of the second bevel gear.

[0009] Preferably, the yarn bobbin unit includes at least two linearly arranged rotating frames, the two ends of which are rotatably mounted on the frame via rotating shafts, and multiple sleeve rods for mounting the yarn bobbin are arranged linearly and spaced apart on both sides of the rotating frames.

[0010] Preferably, the frame is provided with a rotary drive that drives the rotating shaft to rotate at an angle so that the two sides of the rotating frame can be reversed. The number of rotary drives corresponds to the number of rotating frames. The frame is provided with a controller that drives the rotary drives, and the rotary drives are electrically connected to the controller.

[0011] Preferably, the rotary driver includes a mounting plate, a driving component disposed on the mounting plate, a transmission component connected to the driving component, and an output shaft that is drively connected to the transmission component, wherein the output shaft rotates synchronously with the rotating shaft.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] In summary, the advantages of this utility model are: The mirrored structure on both sides ensures even stress distribution on the frame, reducing tilting or vibration caused by unilateral loads, enhancing equipment stability, and making it suitable for high-speed warp knitting processes. This also reduces the risk of yarn breakage due to structural swaying. Because the yarn splitting unit and yarn bobbin unit are mirrored, their guide holes correspond one-to-one with the sleeve rods, allowing the yarns on both sides to be guided into the warp knitting work area along symmetrical paths, avoiding cross-side yarn crossing. This is particularly suitable for biaxial warp knitting machines that require synchronous control of yarns on both sides, improving the symmetry and stability of the fabric structure. The yarn splitting unit and the fuzz removal unit are alternately arranged on both sides of the second frame, allowing the yarn to be split and cleaned synchronously during transmission, avoiding the repetitive paths of traditional single-function modules. When it is necessary to change yarn on both sides of the bobbin, the rotating drive can be rotated at an angle to simultaneously realize the rotation reversal and locking action of the bobbin. The bobbin can be fixed without manual adjustment of position multiple times, which saves time and effort and reduces the labor intensity of workers. During operation, the drive component drives the transmission component, the transmission component drives the output shaft to rotate, the output shaft drives the rotating shaft synchronously, and the rotating shaft rotates, thereby driving the bobbin to rotate. The operation is convenient and flexible, saves the space occupied by the bobbin, and realizes automatic yarn changing on both sides of the bobbin, effectively improving work efficiency. 3. Each component of the adjustment mechanism can be disassembled and replaced independently. If a component is worn or damaged, the entire mechanism does not need to be replaced, reducing maintenance costs and downtime. The gear and rack drive has a large tooth surface contact area and low wear, which can withstand the weight of the frame and yarn bobbin and maintain stability during high-speed operation. The bevel gear pair transmits the torque of the operating lever evenly to the cylindrical gear through the interlaced shaft drive, avoiding the slippage or vibration problems that may occur in traditional belt drive or chain drive. At the same time, the bevel gear has high tooth surface contact strength and can withstand large loads, making it suitable for warp knitting production scenarios with frequent adjustments. The input interface and operating lever adopt a detachable design, supporting quick switching between manual operation and electric drive. Attached Figure Description

[0019] 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

[0020] This utility model provides a multi-functional frame for warping, 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.

[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 4 As 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 portion 531 near the drive unit 52 is provided with a limiting groove 5311 that matches 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 portion 531, ensuring that the rack portion 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. Example

[0032] A multi-functional warping frame includes a frame, such as Figure 7 As shown, the frame includes a frame 100 arranged linearly along the longitudinal direction of the coordinate axis, and a crossbeam 200 arranged laterally along the coordinate axis to connect the frame 100. The frame 100 includes a first frame 101 and a second frame 102 mirrored on the left and right sides of the crossbeam 200 along the central axis of the crossbeam 200. The first frame 101 is hinged to the crossbeam 200, and the second frame 102 is movably mounted on the crossbeam 200 through an adjustment mechanism 300. The first frame 101 is provided with a yarn bobbin unit, and the second frame 102 is provided with a yarn splitting unit and a fuzz cleaning unit. The fuzz cleaning unit and the yarn splitting unit are alternately arranged on both sides of the second frame 102.

[0033] The mirrored structure on both sides of this invention ensures uniform stress on the frame, reducing tilting or vibration caused by unilateral loads, enhancing equipment stability, and making it suitable for high-speed warp knitting processes. It also reduces the risk of yarn breakage due to structural swaying. Furthermore, the yarn splitting unit and yarn bobbin unit are mirrored, with their guide holes corresponding one-to-one with the sleeve rods. This allows the yarns on both sides to be guided into the warp knitting working area along symmetrical paths, avoiding cross-side yarn crossing. This is particularly suitable for biaxial warp knitting machines that require synchronous control of yarns on both sides, improving the symmetry and stability of the fabric structure. The yarn splitting unit and the fuzz removal unit are alternately arranged on both sides of the second frame, allowing the yarn to be split and cleaned synchronously during transmission, avoiding the repetitive paths of traditional single-function modules.

[0034] Specifically, such as Figure 8 As shown, the adjustment mechanism 300 includes a rack 301 fixedly mounted on the crossbeam 200, a sliding seat movably mounted on the crossbeam 200, a cylindrical gear 302 mounted on the sliding seat and meshing with the teeth of the rack 301, and a bevel gear pair rigidly connected to the shaft end of the cylindrical gear 302. The bevel gear pair has an input interface, and an operating lever 305 is detachably mounted on the input interface. The sliding seat has multiple pulleys that can slide linearly along the crossbeam, thereby moving the frame 100 to adjust its position and meet the needs of different yarn spacing layouts. The bevel gear pair includes a first bevel gear 303 and a second bevel gear 304, whose axes intersect at a 90° angle. The shaft end of the first bevel gear 303 is rigidly connected to the shaft end of the cylindrical gear 302, and the input interface is located at the shaft end of the second bevel gear 304.

[0035] In this embodiment, each component of the adjustment mechanism can be independently disassembled and replaced. If a component is worn or damaged, the entire mechanism does not need to be replaced, reducing maintenance costs and downtime. The gear and rack drive has a large tooth surface contact area and low wear, which can withstand the weight of the frame and yarn bobbin and maintain stability during high-speed operation. The bevel gear pair transmits the torque of the operating lever evenly to the cylindrical gear through the interlaced shaft drive, avoiding the slippage or vibration problems that may occur in traditional belt drive or chain drive. At the same time, the bevel gear has high tooth surface contact strength and can withstand large loads, making it suitable for warp knitting production scenarios with frequent adjustments. The input interface and operating lever adopt a detachable design, supporting quick switching between manual operation and electric drive.

[0036] Other contents not described in this embodiment two can be referred to in embodiment one, and will not be repeated here.

[0037] 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.
