Description

A bobbin shaft and wire cake cutting and recycling device Technical Field

[0001] This utility model relates to the field of spandex spinning production technology, and in particular to a bobbin shaft and a yarn cake cutting and recycling device. Background Technology

[0002] In the production process of spandex yarn cakes, when scrap-grade spandex yarn cakes are produced, it is often necessary to manually cut the spandex yarns from the paper tube and peel the yarns off the paper tube. This is labor-intensive and the yarn cutting operation is prone to accidental hand injuries.

[0003] While existing paper tube shredders have solved the problems of high labor intensity and safety risks associated with manual shredding, the diameter of the shredder tube shaft remains fixed. Therefore, when cutting waste shredders with different inner diameters, it is necessary to replace the shredder tube shaft with one of different diameters to ensure a tight fit between the inner wall of the paper tube and the tube shaft. If the tube shaft is not replaced, the shredder is prone to lateral displacement during the cutting process, which affects the cutting accuracy.

[0004] Therefore, there is an urgent need to design a bobbin shaft and wire cake cutting and recycling device to solve the above-mentioned technical problems. Summary of the Invention

[0050] As shown in Figures 1 to 4, this embodiment discloses a wire cake cutting and recycling device. The wire cake cutting and recycling device includes a frame 1 and a bobbin shaft 2. The bobbin shaft 2 is movably mounted on the frame 1 along a first direction, which is the axial direction of the bobbin shaft 2. The tube shaft 2 includes at least two sector-shaped support blocks 21, at least two T-shaped plates 22, and a drive assembly. The support blocks 21 are fixed to the external structural components. Along the circumferential direction, at least two support blocks 21 and at least two T-shaped plates 22 are arranged alternately. The circle formed by all the support blocks 21 and the circle formed by all the arc plates 221 are concentrically arranged. The T-shaped plate 22 includes a connected arc plate 221 and a transmission plate 222. The arc plate 221 is located outside the support block 21, and the transmission plate 222 is located in the gap between two adjacent support blocks 21. The drive assembly includes a driven gear 23, which is located at the center of the circle formed by all the arc plates 221. The driven gear 23 is provided with at least two sliding grooves 231 along the circumferential direction. The end of the transmission plate 222 away from the arc plate 221 is movably disposed in the sliding groove 231. When the driven gear 23 rotates, the T-shaped plate 22 moves radially.

[0051] The bobbin shaft 2 provided in this embodiment has a variable outer diameter structure. When the driven gear 23 rotates, the sliding groove 231 drives the transmission plate 222 to move radially, thereby causing the arc plate 221 to move radially, thus achieving the purpose of changing the outer diameter of the bobbin shaft 2. When the outer diameter of the bobbin shaft 2 increases, the arc plate 221 can press against the inner wall of the paper tube, thereby fixing the wire cake. The support block 21 has a limiting function on the T-shaped plate 22. Specifically, since the support block 21 is fixed, the support block 21 restricts the displacement direction of the T-shaped plate 22 to only the radial direction. This wire cake cutting and recycling device can adjust the outer diameter of the bobbin shaft 2 online, ensuring that the bobbin shaft 2 fits tightly against the inner wall of paper tubes of different diameters, ensuring cutting accuracy without replacing the bobbin shaft 2, thereby adapting to wire cakes of different inner diameters and meeting different wire cutting needs.

[0052] Optionally, as shown in Figure 3, the T-shaped plate 22 further includes a sliding shaft 223. The sliding shaft 223 is connected to the end of the transmission plate 222 away from the arc-shaped plate 221, and is movably disposed within the sliding groove 231. When the driven gear 23 rotates, the sliding shaft 223, movably disposed within the sliding groove 231, slides along the sliding groove 231, thereby driving the transmission plate 222 to move radially, and further driving the arc-shaped plate 221 to move radially, thereby changing the outer diameter of the circle formed by all the arc-shaped plates 221, that is, achieving the purpose of changing the outer diameter of the cylinder shaft 2.

[0053] The sliding shaft 223 is axially fixedly connected to the side of the transmission plate 222. In this embodiment, the arc-shaped plate 221 and the transmission plate 222 are integrally formed. Of course, in other feasible embodiments, the arc-shaped plate 221 and the transmission plate 222 can also be two parts fixedly connected. The sliding shaft 223 and the transmission plate 222 can be two parts fixedly connected, or they can be an integrally formed structure.

[0054] In this embodiment, the sliding shaft 223 is a cylindrical shaft; the sliding groove 231 is a strip-shaped groove, and the sliding shaft 223 and the sliding groove 231 are in clearance fit, that is, the diameter of the sliding shaft 223 is slightly smaller than the width of the sliding groove 231. Optionally, the center line of the sliding groove 231 is an arc, that is, the sliding groove 231 is an arc-shaped groove, and as the driven gear 23 rotates, the sliding shaft 223 moves along the arc-shaped groove.

[0055] To better achieve the transmission motion between the driven gear 23 and the T-shaped plate 22, at least two sliding grooves 231 are centrally symmetrically arranged about the center of the driven gear 23. With this structure, the radial movement of all T-shaped plates 22 is synchronized.

[0056] In this embodiment, only one ring of T-shaped plates 22 is provided along the axial direction. The number of support blocks 21 and T-shaped plates 22 is the same, with six of each. The number of sliding grooves 231 is the same as the number of T-shaped plates 22, with six of each. Of course, in actual production, the number of support blocks 21, T-shaped plates 22, and sliding grooves 231 can be adjusted according to actual needs, and will not be listed here.

[0057] In this embodiment, as shown in FIG4, the drive assembly further includes a drive gear 24, a drive motor 26, and a torque limiter 25. The drive gear 24 meshes with the driven gear 23, and the output end of the drive motor 26 is connected to the drive gear 24 through the torque limiter 25. When the arc plate 221 abuts against the inner wall of the paper tube, the torque limiter 25 detects the increase in torque and controls the motor to stop.

[0058] In existing technologies, such as the technical solution disclosed in document CN115123883A, although the tube shaft diameter can be adjusted, the outer diameter adjustment process requires simultaneous and synchronous adjustment of two rotating handles to ensure that the stroke of the guide rod parallelogram is consistent; otherwise, the arc plate cannot smoothly change the outer diameter. That is, the levelness of the arc plate is directly related to whether the adjustment strokes of the two rotating handles are the same, and the levelness is closely related to the thread rotation of the two rotating handles. In this embodiment, the tube shaft 2 needs to be interference-fitted with multiple paper tubes simultaneously, therefore, levelness is very important. If the levelness of the arc plate 221 relies on manual adjustment, individual paper tubes at the end are prone to loosening and slipping out. However, the structure and adjustment method of the tube shaft 2 in this embodiment can avoid the loosening of individual paper tubes.

[0059] First, in this embodiment, the tube shaft 2 is limited in the sliding groove 231 of the driven gear 23 by the sliding shaft 223 of the T-shaped plate 22, and the gear pair is driven to move by the drive motor 26. In terms of structure and adjustment method, it ensures the horizontality of the arc plate 221, without the need for manual adjustment, and the adjustment accuracy is high.

[0060] Secondly, regarding the paper tube clamping method, this embodiment uses a torque limiter 25 that allows for flexible torque value setting. When the bobbin shaft 2 contacts the paper tube, if the torque value exceeds the set value, the drive motor 26 stops rotating, and the drive motor 26 has a built-in "brake" function. This ensures that the bobbin shaft 2 and the paper tube are in an interference fit, and the clamping degree can be quantitatively adjusted. In contrast, in the prior art, after the paper tube contacts the shaft, the rotating handle cannot be rotated further, requiring manual subjective judgment to determine whether the paper tube is clamped, resulting in lower adjustment accuracy.

[0061] As shown in Figure 2, the length of the T-shaped plate 22 is less than the length of the support block 21 along the axial direction. In this structure, one end of the support block 21 extends beyond the T-shaped plate 22, and this end can be fixed to an external structural component. To improve the overall aesthetic appearance, one end of the T-shaped plate 22 and one end of the support block 21 are flush, and the other end of the support block 21 extends beyond the other end of the T-shaped plate 22 by a certain length. The length difference between the two can be designed according to the actual situation.

[0062] The axial dimension of the T-shaped plate 22 can be adjusted and replaced according to actual needs. That is, one or more T-shaped plates 22 can be set in the axial direction.

[0063] Specifically, when multiple rolls of wire with the same inner diameter need to be simultaneously fitted onto the bobbin shaft 2, the technical solution shown in Figure 3 can be adopted. That is, the axial dimension of the T-shaped plate 22 is relatively long, and only one ring of T-shaped plate 22 is provided in the axial direction. With this structure, the outer diameter of the bobbin shaft 2 is equal everywhere, and multiple rolls of wire with the same inner diameter can be fitted onto any position on the bobbin shaft 2. This embodiment is illustrated using this structure as an example. Of course, multiple rings of T-shaped plates 22 can also be provided at intervals in the axial direction, with each ring of T-shaped plates 22 forming a circle of the same diameter. With this structure, the axial dimension of any ring of T-shaped plates 22 is not large, and the ring of arc-shaped plates 221 only needs to abut against and tighten the inner wall of the paper tube corresponding to the wire roll. It should be noted that "multiple rings" here refers to at least two rings, that is, two or more rings. It should also be noted that when multiple T-shaped plates 22 are spaced apart along the axial direction, the sliding shaft 223 of the T-shaped plate 22 closest to the driven gear 23 is clearance-fitted with the sliding groove 231. Adjacent T-shaped plates 22 are interlocked and limited in a direction gradually moving away from the driven gear 23, thereby achieving the driving effect of the driven gear 23 on all T-shaped plates 22. Specifically, the T-shaped plates 22 are provided with insertion holes (not shown), and the insertion holes and sliding shafts 223 are respectively located on both sides of the transmission plate 222 and are correspondingly arranged, i.e., the insertion holes and sliding shafts 223 are collinear. In this structure, when two adjacent T-shaped plates 22 are interlocked, the sliding shaft 223 of the T-shaped plate 22 relatively far from the transmission gear 23 can be inserted into the insertion hole of the T-shaped plate 22 relatively close to the transmission gear 23, thereby achieving linkage between the multiple T-shaped plates 22.

[0064] When multiple rolls of wire cake with different inner diameters need to be simultaneously fitted onto the bobbin shaft 2, multiple T-shaped plates 22 are spaced apart along the axial direction. The diameter of the circle formed by the T-shaped plates 22 in each ring is different to accommodate wire cakes with different inner diameters. In this structure, the axial dimension of any ring of T-shaped plates 22 is not large, and the arc plate 221 of the ring only needs to abut against and tighten the inner wall of the paper tube corresponding to the wire cake. It should be noted that "multiple rings" here refers to at least two rings, that is, two or more rings. It should also be noted that when multiple rings of T-shaped plates 22 are spaced apart along the axial direction, the sliding shaft 223 of the T-shaped plate 22 closest to the driven gear 23 is clearance-fitted with the sliding groove 231. Along the direction gradually moving away from the driven gear 23, adjacent T-shaped plates 22 are interlocked and limited to each other to realize the driving effect of the driven gear 23 on all T-shaped plates 22. Specifically, the T-shaped plate 22 is provided with insertion holes (not shown). The insertion holes and the sliding shaft 223 are respectively located on both sides of the transmission plate 222 and are correspondingly arranged, that is, the insertion holes and the sliding shaft 223 are collinear. In this structure, when two adjacent T-shaped plates 22 are inserted into each other, the sliding shaft 223 of the T-shaped plate 22 that is relatively far away from the transmission gear 23 can be inserted into the insertion hole of the T-shaped plate 22 that is relatively close to the transmission gear 23, thereby realizing the linkage between multiple turns of the T-shaped plates 22.

[0065] To secure the support block 21, the wire cake cutting and recycling device in this embodiment further includes a bobbin shaft fixing bracket 5. One end of the bobbin shaft fixing bracket 5 is fixedly connected to the support block 21, and the other end is slidably connected to the frame 1. Specifically, the bobbin shaft fixing bracket 5 has an inner hole and is sleeved on the outside of the support block 21. An interference fit can be made between the support block 21 and the inner hole of the bobbin shaft fixing bracket 5 to secure the bobbin shaft 21 to the bobbin shaft fixing bracket 5. Only with the support block 21 fixed in position can the radial movement of the T-shaped plate 22 be limited.

[0066] To achieve a sliding connection between the bobbin shaft 2 and the frame 1, the wire cake cutting and recycling device in this embodiment further includes a sliding assembly. The sliding assembly includes a slide rail 3 and a slider 4. The slide rail 3 extends along a first direction and is disposed on the frame 1. One end of the slider 4 is slidably connected to the slide rail 3, and the other end is fixedly connected to the bobbin shaft fixing frame 5. By setting the sliding assembly, a sliding connection between the bobbin shaft fixing frame 5 and the frame 1 is achieved, thereby realizing a sliding connection between the bobbin shaft 2 and the frame 1.

[0067] There are two slide rails 3, which are spaced apart on the frame 1 along a second direction, which is perpendicular to the first direction. The slider 4 has a groove, which connects it to the slide rail 3. The groove of the slider 4 has the same cross-section as the slide rail 3, allowing the slider 4 to slide linearly on the slide rail 3.

[0068] Optionally, the wire cake cutting and recycling device in this embodiment further includes a bobbin shaft protective cover 6, which is fixed to the bobbin shaft fixing frame 5. The diameter of the bobbin shaft protective cover 6 is larger than the diameter of the circle formed by all the support blocks 21. The bobbin shaft protective cover 6 is used to protect the bobbin shaft 2, prevent it from being bumped by the outside world, and avoid damage to the bobbin shaft 2.

[0069] Optionally, the wire cake cutting and recycling device in this embodiment further includes a metal detection unit 7, which is mounted on the frame 1. The metal detection unit 7 is used to detect metal foreign objects entrained in the wire cake; when a metal foreign object is detected, an alarm is sounded. The support block 21 and the T-shaped plate 22 are both made of non-metallic materials to avoid false alarms from the metal detection unit 7.

[0070] As shown in Figure 1, the wire cake cutting and recycling device in this embodiment also includes a circular blade motor 8, a circular blade 9, a circular blade base plate 10, a waste wire bucket 11, a connecting plate 12, a manual push rod 13, and a cylinder 14. A metal detection unit 7 is fixed on the circular blade base plate 10 and located in front of the circular blade 9. The motor shaft of the circular blade motor 8 is directly connected to the circular blade 9, and the circular blade motor 8 is fixed on the circular blade base plate 10. The circular blade 9 is located in the through-hole groove of the circular blade base plate 10. The circular blade base plate 10 is fixed on the frame 1. The waste wire bucket 11 is placed below the frame 1 to catch the cut wire. The bobbin shaft fixing bracket 5 and the slider 4 are fixed through the connecting plate 12. There are four sliders 4, with two sliders 4 spaced apart along the first direction on each slide rail 3. That is, the connecting plate 12 is connected to the slide rail 3 through four sliders 4, improving structural stability and reliability. Of course, only one slider 4 can be provided on each slide rail 3. A manual push rod 13 is mounted on the connecting plate 12. By pushing the manual push rod 13, the bobbin shaft 2 moves linearly along the first direction, sending the yarn cake on the bobbin shaft 2 to the bottom of the circular knife 9 for cutting. The end of the cylinder 14 is fixed to the connecting plate 12, causing the connecting plate 12 and the bobbin shaft 2 to move back and forth along the first direction. After the spandex yarn cake is inserted into the bobbin shaft 2, the outer diameter of the bobbin shaft 2 is adjusted to hold the yarn cake in place, and the manual push rod 13 is moved to send the yarn cake to the bottom of the circular knife 9 for cutting.

[0071] As shown in Figure 1, the metal detection unit 7 is installed between the circular cutter 9 and the bobbin shaft 2, with the detection area being the wire cake directly below it. After the wire cake is fitted onto the bobbin shaft 2 and fixed, the manual push rod 13 is pushed, moving the bobbin shaft 2 towards the circular cutter 9. The metal detection unit 7 then checks each wire cake for any metal foreign objects. When a metal foreign object is detected in the wire bundle, an alarm sound is emitted to promptly remind the person to stop pushing the manual push rod 13 and prevent further wire feeding below the circular cutter 9. Simultaneously, the detection signal interlocks to stop the power supply to the circular cutter motor 8, preventing the circular cutter 9 from rotating and encountering a metal foreign object, which could cause the blade to break.

[0072] As shown in Figure 4, after the drive motor 26 starts rotating forward, it drives the driving gear 24 to rotate, and the driven gear 23 rotates synchronously. The sliding shaft 223 in the sliding groove 231 of the driven gear 23 is driven by the driven gear 23 to make radial displacement. The sliding shaft 223 drives the arc plate 221 to make radial displacement synchronously through the transmission plate 222, and presses against the inner wall of the paper tube.

[0073] As shown in Figures 2 and 4, when the arc-shaped plate 221 presses against the inner wall of the paper tube, the sliding shaft 223, driven gear 23, and driving gear 24 will be unable to continue operating. The torque limiter 25 will detect the increased torque and then control the drive motor 26 to stop operating. The drive motor 26 can rotate in both directions and has a braking function to prevent the arc-shaped plate 221 from retracting, thus achieving the function of adapting to different inner diameters of paper tubes.

[0074] The working process of the wire cake cutting and recycling device, as shown in Figures 1 and 2, is briefly described as follows: First, the drive motor 26 reverses, retracting the transmission plate 222 of the T-shaped plate 22 between the adjacent support blocks 21. Then, the paper tube of the wire cake to be cut is manually inserted, and the drive motor 26 is started to rotate forward, driving the T-shaped plate 22 to extend out of the support block 21 and causing the arc plate 221 to press against the inner wall of the paper tube of the wire cake. At this time, the torque limiter 25 will control the drive motor 26 to stop. Then, the drive motor 26 is manually reversed slightly to maintain a clearance fit between the paper tube and the bobbin shaft 2, thereby completing the adjustment of the bobbin shaft 2. Afterwards, when the inner diameter of the new paper tube changes, the above steps can be repeated for calibration.

[0075] It should be noted that in this application, the circular blade 9 damages the surface of the paper tube while cutting the filaments. For efficiency reasons, the paper tube is cut off along with the filaments, avoiding repeated cutting. In existing filament cutting devices, if the filament cutting device does not cut the paper tube, a thin layer of filaments will inevitably remain on the surface of the paper tube, requiring manual peeling or the melting of the last few layers of thin filaments with a high-temperature hot blade. The outer surface of the spandex paper tube has a thin and smooth plastic coating used to distinguish spandex batch numbers. The high-temperature hot blade will also affect the plastic film on the surface of the paper tube, making it unusable as a new paper tube. Moreover, compared to the cost of manual filament peeling, the cost of paper tube recycling is lower. Therefore, the filament cutting and recycling device in this application directly cuts off the paper tube along with the filaments.
