Description

Technical Field

[0001] The present invention relates to the technical field of chemical fiber winding, in particular to a switching device for a chemical fiber winding machine. Background Art

[0002] Currently, in the production and manufacturing of chemical fiber filaments, winders, as core production equipment, undertake the key task of winding the spun filaments into standard packages with specific shapes and capacities. Modern filament production generally uses fully automatic winders. With their mechanism switching function, they can realize the transfer and splicing of filaments between two spindles, ensuring the continuous operation of the production line around the clock and significantly improving production efficiency.

[0003] However, the existing winding machines still have obvious technical shortcomings in the winding link. When the chemical fiber yarn is wound, the winding shaft needs to be removed as a whole, but the subsequent operations still rely on manual connection of the chemical fiber yarn to the newly replaced winding shaft before continuing the next stage of winding operation. This manual operation process not only consumes a lot of manpower, but also has low efficiency in replacing the winding shaft due to the cumbersome operation steps, which in turn affects the overall continuity and production rhythm of the production line. In addition, during the manual connection process, the operation accuracy and stability are difficult to guarantee, and problems such as loose connection and chemical fiber yarn breakage are prone to occur, which increases the defective rate and increases production costs. It can be seen that the existing winding equipment lacks the function of assisting in quickly connecting the chemical fiber yarn and the winding shaft, which makes the production process complicated and inconvenient. It can be seen that the existing technology has certain defects and deficiencies, so it needs to be improved and designed.

[0004] To this end, we propose a chemical fiber winding machine switching device to solve the above problems. Summary of the Invention

[0018] First, in the present invention, the device can effectively improve the flexibility and adjustment efficiency of the winding shaft specification adaptation through the coordinated design of the mechanical transmission structure. The third motor drives the third screw to drive the clamping arm to slide back and forth. Based on the mechanical characteristics of the reverse threads at both ends of the third screw, the distance between the two clamping arms can be accurately adjusted in a short time. Without manual measurement or tool assistance, it can quickly adapt to winding shafts of different lengths. This function avoids the disadvantage of traditional equipment that requires frequent replacement of the entire machine or components due to differences in winding shaft specifications, reduces equipment downtime and maintenance costs, and is particularly suitable for multi-variety, small-batch chemical fiber filament production scenarios, enabling the production line to quickly switch product specifications, thereby improving the versatility of the equipment and the flexibility of production scheduling;

The clamping block and slot locking structure between the mounting block and the mounting rail utilizes the principles of inclined plane transmission and spring return to realize the rapid clamping and positioning of the winding shaft, avoiding the tedious steps of manual alignment and significantly shortening the single installation time. During disassembly, the winding shaft can be quickly removed by adjusting the armrest linkage clamping block out of the slot, and the gravity vertical positioning effect of the weight-bearing ball at the bottom of the mounting rail is combined to ensure that the mounting rail always maintains a standard posture during the disassembly process, reducing the difficulty of operation, while avoiding the problem of winding shaft tilting or jamming due to improper manual operation, thereby improving the installation accuracy and the stability of equipment operation.

[0020] Third, in the present invention, during the application of this device, the integrated design of its switching mechanism and the automated winding process has completely changed the inefficient mode of traditional manual connection of chemical fiber yarns. Through the linkage control of the first motor and the second motor, the clamping arm can automatically complete the grabbing, clamping and transfer of the chemical fiber yarn ends, avoiding the risk of contamination or breakage caused by manual contact with the yarn bundle. During the winding process, the buffering effect of the telescopic spring effectively absorbs tension fluctuations; the electric push rod drives the correction guide ring to swing horizontally, so that the chemical fiber yarn is evenly distributed axially on the winding shaft, and the consistency of the package density is significantly better than the manual operation level. The entire winding process does not require manual intervention, and is fully automated from yarn head clamping to package forming, which significantly improves the continuous operation efficiency of the production line, while reducing labor costs and improving product quality stability and production efficiency.

[0031] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] Example 1:

[0033] like Figures 1-10 As shown, the present invention discloses a switching device for a chemical fiber winding machine, comprising a base 1, on which a mounting mechanism 2 is fixedly mounted. The mounting mechanism 2 is used to mount a reel 5 and drive the reel 5 to rotate. A reeling pre-reserved groove 4 is axially opened in the middle of the reel 5, and the reeling pre-reserved groove 4 radially penetrates the reel 5. A switching mechanism 3 is fixedly mounted on the rear side of the base 1;

[0034] The switching mechanism 3 includes an adjusting component 31, which is fixedly installed in the middle of the rear side of the base 1. A buffer component 32 is installed on the adjusting component 31. The adjusting component 31 drives the buffer component 32 to approach or move away from the winding shaft 5. A connecting rod 33 is fixedly installed on the top of the buffer component 32, and a clamping component 34 is fixedly installed on one end of the connecting rod 33 close to the winding shaft 5; the clamping component 34 corresponds to the winding reserved slot 4, and when the buffer component 32 approaches the winding shaft 5, the clamping component 34 passes through the winding reserved slot 4.

[0035] During the application of this device, when the chemical fiber winding machine switching device is working, the base 1 fixes the winding shaft 5 through the mounting mechanism 2, and the winding reserved groove 4 is passed through by the switching mechanism 3 to realize the connection of the yarn bundle. After the adjusting component 31 is started, it drives the buffer component 32 to move longitudinally along the rear side of the base 1, that is, close to the winding shaft 5. The buffer component 32 transmits the displacement through the connecting rod 33, so that the clamping component 34 extends into and passes through the winding reserved groove 4. When the chemical fiber needs to be wound, the clamping component 34 clamps the end of the yarn bundle, and the adjusting component 31 moves in the opposite direction to pull the yarn bundle out of the winding reserved groove 4 and position it to the surface of the winding shaft 5. Then the winding shaft 5 rotates and starts winding. During the winding process, the elastic structure of the buffer component 32 can absorb the tension fluctuation of the yarn bundle to avoid breakage; when the yarn bundle completes the initial winding on the winding shaft 5, the clamping component 34 is released, the switching mechanism 3 is reset, and the winding shaft 5 continues to wind until the operation is completed. The entire process realizes the automatic connection of the chemical fiber yarn from clamping, transfer to winding through mechanical linkage.

[0036] like Figure 1-Figure 4 As shown, the adjustment component 31 includes a guide rail 311, which is fixedly mounted on the base 1, and a first motor 312 is fixedly mounted on one end of the guide rail 311, and a first screw rod 313 is fixedly mounted on the output end of the first motor 312, and the first screw rod 313 is rotatably connected to the inside of the guide rail 311, and a slider 314 is threadedly connected to the outer surface of the first screw rod 313, and the slider 314 is slidably connected to the guide rail 311, and the top of the slider 314 is fixedly connected to the bottom of the buffer component 32; the buffer component 32 includes a movable frame 321, which is fixedly mounted on the top of the slider 314, and a telescopic spring 322 is provided on the inner side of the movable frame 321 near the winding shaft 5, and the end of the telescopic spring 322 is fixedly connected to the stand 323, and the stand 323 is slidably connected in the movable frame 321. The connecting rod 33 is fixedly mounted on the top of the stand 323; the clamping assembly 34 includes a side rail 341, which is fixedly mounted on the front end of the connecting rod 33, that is, one end close to the winding shaft 5. The internal rotation of the side rail 341 is connected to the second screw rod 342, and the two ends of the second screw rod 342 have opposite threads. Both ends of the second screw rod 342 are threadedly connected to a movable block 343, and the movable block 343 is slidably connected to the side rail 341. The outer side of the movable block 343 is fixedly connected to the clamping rod 344, and the inner side of the outer end of the clamping rod 344 is fixedly connected to the splint 345, and the inner side of the splint 345 is fixedly connected to the anti-skid plate 346, and the inner side of the anti-skid plate 346 is provided with anti-slip grooves. One end of the side rail 341 is fixedly mounted with a second motor 347, and the output end of the second motor 347 is connected to one end of the second screw rod 342.

[0037] During the application of this device, the adjustment component 31 of its switching device drives the first screw rod 313 to rotate through the first motor 312, driving the slider 314 to slide back and forth along the guide rail 311, thereby causing the buffer component 32 fixed on the top of the slider 314 to move longitudinally. In the buffer component 32, the telescopic spring 322 in the movable frame 321 is connected to the vertical frame 323. When the slider 314 moves, the telescopic spring 322 can absorb the impact force during the displacement process by compression or tension, ensuring that the connecting rod 33 at the top of the vertical frame 323 moves stably. One end of the telescopic spring 322 is fixed to the end of the movable frame 321 near one end of the winding shaft 5, and the other end of the telescopic spring 322 is fixed to the vertical frame 323. In the natural state, the vertical frame 323 is located in the middle part of the movable frame 321. When the clamping assembly 34 at the front end of the connecting rod 33 is working, the second motor 347 drives the second screw rod 342 to rotate, and uses the reverse thread characteristics at both ends to make the movable blocks 343 on both sides move toward or away from each other, and the clamping rod 344 drives the splint 345 to open and close. The anti-slip plate 346 and anti-slip grooves on the inside of the splint 345 can enhance the clamping force on the chemical fiber yarn. When the slider 314 drives the clamping assembly 34 to extend into the winding reserved groove 4, the splint 345 closes and clamps the wire head, and then the slider 314 moves in the opposite direction to pull the yarn bundle out of the winding reserved groove 4 and position it to the surface of the winding shaft 5. The winding shaft 5 rotates and starts winding. During the winding process, the telescopic spring 322 buffers the tension fluctuations of the yarn bundle. After the yarn bundle completes the initial winding, the splint 345 is released, and the switching mechanism 3 is reset, realizing the automatic linkage of the chemical fiber yarn from clamping and transfer to winding.

[0038] like Figure 5-Figure 8As shown, the mounting mechanism 2 includes a rail frame 211, the rail frame 211 is fixedly mounted on the middle part of the base 1, one end of the rail frame 211 is fixedly mounted with a third motor 212, the output end of the third motor 212 is connected to a third screw rod 213, the third screw rod 213 is rotatably connected to the inside of the rail frame 211, the two ends of the third screw rod 213 have opposite thread rotation directions, and both ends of the third screw rod 213 are threadedly connected to a sliding block 214, the sliding block 214 is slidably connected to the rail frame 211, and the sliding block The top of 214 is fixedly connected to a clamping arm 215, and the top of the clamping arm 215 is fixedly connected to a mounting assembly 216. The reel 5 is installed between the mounting assemblies 216; the mounting assembly 216 includes a top plate 2161, which is fixedly mounted on the top of the clamping arm 215. The top plates 2161 are rotatably connected to the limit groups 2162. The reel 5 is installed between the top plates 2161 through the limit groups 2162. The outer side of one of the top plates 2161 is fixedly mounted with a fourth motor 216 3. The output end of the fourth motor 2163 is in transmission connection with the limit group 2162 on the top plate 2161; the limit group 2162 includes a turntable 21621, which is rotatably connected to the top plate 2161. A mounting rail 21623 is fixedly installed on the inner side of the turntable 21621. Mounting blocks 21624 are provided at both ends of the winding shaft 5. The mounting blocks 21624 are plugged into the mounting rail 21623. A concave frame 21625 is fixedly connected to one side of the mounting rail 21623. The concave frame 21625 is fixedly installed on one side of the mounting rail 21623. A limiting spring 21626 is provided inside the concave frame 21625. A clamping block 21627 is fixedly installed on the end of the limiting spring 21626. The end of the clamping block 21627 passes through the mounting rail 21623 and extends to the inside of the mounting rail 21623. A clamping slot 21622 is provided on one side of the mounting block 21624. When the mounting block 21624 is inserted into the mounting rail 21623, the clamping block 21627 is inserted into the clamping slot 21622.

[0039] During the application of this device, when the mounting mechanism 2 is working, the third motor 212 is started and drives the third screw rod 213 to rotate in the rail frame 211. The reverse thread characteristics of the two ends of the third screw rod 213 are used to drive the sliding blocks 214 at both ends to move toward or away from each other along the rail frame 211, thereby driving the clamping arms 215 on the top of the sliding blocks 214 to move synchronously, thereby realizing the adjustment of the spacing between the clamping arms 215 to adapt to the winding shafts 5 of different lengths. When installing the winding shaft 5, align the mounting blocks 21624 at both ends of the winding shaft 5 with the mounting rail 21623 and insert them. The front end of the mounting block 21624 squeezes the clamping block 21627, so that the clamping block 21627 is compressed by the limit spring 21626 and moves outward; when the mounting block 21624 is fully inserted, the clamping slot 21622 on it corresponds to the position of the clamping block 21627, the limit spring 21626 resets and pushes the clamping block 21627 to move, and the clamping block 21627 is embedded in the clamping slot 21622, completing the clamping and fixing of the winding shaft 5 and the mounting rail 21623. After installation is complete, the fourth motor 2163 drives the connected turntable 21621 to rotate, which in turn drives the mounting rail 21623 and the reel 5 to rotate synchronously, commencing the filament reeling operation. After reeling is complete, the clamping block 21627 is disengaged from the clamping slot 21622 by external force, allowing the reel 5 to be removed from the inside of the mounting rail 21623, completing the entire installation, use, and removal process of the reel 5. The top plate 2161 is actually a shaft seat, and the turntable 21621 is a short shaft, with the two being rotatably connected.

[0040] like Figure 1-Figure 4 、 Figure 9 As shown, a connecting shaft 216210 is fixedly connected to the outer side of the clamping block 21627. The outer end of the connecting shaft 216210 passes through the concave frame 21625. An adjustable handrail frame 216211 is fixedly connected to the connecting shaft 216210 outside the concave frame 21625. A weighted ball 21628 is fixedly mounted to the bottom of the mounting rail 21623, and a guide slope 21629 is defined on the upper end of the clamping block 21627. A mounting frame 6 is fixedly mounted to the front end of the base 1. An electric push rod 7 is fixedly mounted on the upper end of the mounting frame 6. A connecting frame 8 is fixedly mounted to the output end of the electric push rod 7. A correction guide ring 9 is fixedly mounted on the connecting frame 8.

[0041] During use of this device, the weighted ball 21628 at the bottom of the mounting rail 21623, through its own gravity, keeps the mounting rail 21623 in a vertical position during the assembly and disassembly of the reel 5, providing stable support for the rapid alignment of the mounting block 21624 with the mounting rail 21623 and simplifying the installation process. When disassembling the reel 5, the adjusting armrest 216211 is pulled to drive the connecting shaft 216210, thereby causing the clamping block 21627 to move outward, overcoming the elastic force of the limit spring 21626. The clamping block 21627 disengages from the slot 21622, releasing the limit on the mounting block 21624 and enabling the rapid disassembly of the reel 5. The design of the guide slope 21629 facilitates the movement of the clamping block 21627 when the mounting block 21624 is inserted into the mounting rail 21623, reducing installation resistance. During the winding process of the chemical fiber yarn, the chemical fiber yarn passes through the correction guide ring 9. The electric push rod 7 is installed on the mounting frame 6. The connecting frame 8 is driven by its output end to drive the correction guide ring 9 to perform lateral displacement and swing, so that the chemical fiber yarn is evenly distributed in the axial direction of the winding shaft 5, ensuring the uniformity and consistency of the winding.

[0042] The working principle of the present invention is as follows: the present device can realize the functions of rapid adaptation, installation, winding and disassembly of the winding shaft 5 through the coordinated cooperation of the mechanical transmission structure. Specifically, during use, after the third motor 212 is started, it drives the third screw rod 213 to rotate inside the rail frame 211. The reverse thread characteristics of the two ends of the third screw rod 213 are utilized to drive the sliding block 214 to slide back and forth along the rail frame 211, thereby causing the clamping arm 215 on the top of the sliding block 214 to move synchronously, thereby realizing the adjustment of the distance between the two clamping arms 215. The adjustment process converts the rotational motion of the screw rod into the linear motion of the sliding block 214. Based on the accuracy of the mechanical transmission, the distance between the clamping arms 215 can be flexibly adjusted according to the length of the winding shaft 5 to adapt to winding shafts 5 of different specifications.

[0043] During the application of this device, in the installation link of the winding shaft 5, when the spacing adjustment of the clamping arms 215 is completed, the mounting block 21624 is inserted into the mounting rail 21623. When the guide inclined surface 21629 at the front end of the mounting block 21624 contacts the card block 21627, the thrust of the inclined surface causes the card block 21627 to move outward and compress the limit spring 21626. When the mounting block 21624 is fully inserted into the mounting rail 21623, the card groove 21622 on its surface corresponds to the position of the card block 21627. At this time, the limit spring 21626 is reset due to the loss of the squeezing effect of the inclined surface of the mounting block 21624, pushing the card block 21627 to move and embed into the card groove 21622, forming a mechanical card connection structure between the card block 21627 and the card groove 21622, thereby realizing the stable positioning of the mounting block 21624 in the mounting rail 21623. After the installation of the winding shaft 5 is completed, the fourth motor 2163 is started to drive the turntable 21621 to rotate. The turntable 21621 drives the mounting rail 21623 and the winding shaft 5 to rotate synchronously through the transmission structure to complete the winding operation of the chemical fiber yarn. After the winding is completed, the armrest frame 216211 is pulled to adjust the movement of the clamping block 21627 through the connecting shaft 216210, so that the clamping block 21627 disengages from the clamping slot 21622, and the limiting state of the mounting block 21624 is released, and the winding shaft 5 can be removed from the inside of the two mounting rails 21623. In addition, the weighted ball 21628 arranged at the bottom of the mounting rail 21623 ensures that the mounting rail 21623 always maintains a vertical direction during the disassembly and assembly of the winding shaft 5 through the action of gravity, providing physical support for the rapid alignment of the mounting block 21624 and the mounting rail 21623, thereby simplifying the operation process.

[0044] This device realizes the automatic connection between the chemical fiber yarn and the winding shaft 5 through the switching mechanism 3. After the winding shaft 5 is installed in place, the first motor 312 is started to drive the first screw rod 313, so that the slider 314 drives the clamping assembly 34 to move toward the winding reserved groove 4 and extend into the groove, and the chemical fiber yarn end is placed between the inner sides of the two clamps 345. The second motor 347 drives the second screw rod 342, so that the second screw rod 342 drives the two movable blocks 343 to move toward each other, and then the clamping rod 344 drives the clamping plate 345 to clamp the chemical fiber yarn end. After the clamping is completed, the first motor 312 drives the slider 314 in the reverse direction, driving the clamping assembly 34 to withdraw from the winding reserved groove 4, so that the clamped chemical fiber yarn passes through the winding reserved groove 4 and is exposed to the outside of the winding shaft 5. At this time, the fourth motor 2163 is started, and the winding shaft 5 is driven to rotate through the turntable 21621 to wind the chemical fiber yarn. During the winding process, the traction force of the chemical fiber yarn drives the clamping assembly 34 to move toward the winding shaft 5, and the telescopic spring 322 provides a buffering force through compression deformation to prevent the yarn head from breaking due to sudden tension changes. After the chemical fiber yarn completes the initial winding on the surface of the winding shaft 5, the second motor 347 moves again to loosen the clamp 345, and the chemical fiber yarn maintains a stable winding state by relying on the friction between itself and the winding shaft 5. To ensure the uniformity of winding, the chemical fiber yarn passes through the correction guide ring 9, and the electric push rod 7 drives the connecting frame 8 to drive the guide ring to swing horizontally, so that the chemical fiber yarn is evenly distributed in the axial direction of the winding shaft 5. The consistency of the package density is achieved through the regular control of mechanical movement. In the entire winding process, all links from clamping the chemical fiber yarn end, starting the winding to releasing the splint 345 are driven by the motor, reducing manual intervention, realizing automated operation through the linkage of the mechanical structure, and improving the continuity of the production process and the convenience of operation.
