Description

Technical Field

[0001] This utility model relates to the technical field of warping machines, specifically a differential warping machine that does not require stopping. Background Technology

[0002] A warping machine is a type of textile machinery used to evenly and parallelly wind yarn cones onto a warp beam according to the required number of yarns, length, and tension for subsequent weaving processes. There are many types of warping machines, which can be categorized into beam warping, sliver warping, and ball warping, depending on different process requirements and yarn types.

[0003] During the warping process, the linear speed of the yarn naturally increases with the increase of the warp beam diameter. Maintaining a constant linear speed is crucial to ensure uniform yarn tension throughout the warping process. Differential speed regulation is necessary to automatically adjust the spindle speed, reducing it as the warp beam diameter changes, thus maintaining a constant linear speed and preventing uneven tension and yarn quality degradation caused by speed variations. Existing differential warping machines achieve speed regulation through frequency converter technology. The core of this technology lies in adjusting the motor's power supply frequency via a frequency converter, thereby achieving precise speed control of the warping machine. The frequency converter receives the linear speed signal from a tachogenerator, processes it through a PLC, and adjusts the output frequency to control the motor speed. The PLC control system needs to be linked with multiple devices (such as the frequency converter, motor, and tachogenerator). While the combination of frequency converter and PLC enables efficient speed control, its operation is complex, potentially increasing the difficulty of system debugging and maintenance, and requiring a high level of technical expertise from operators. Summary of the Invention

[0004] The purpose of this invention is to provide a differential warping machine that does not require downtime, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A differential warping machine that does not require stopping includes a mounting frame, on which a yarn feed shaft and a warp beam are rotatably mounted in sequence along the yarn feeding direction;

[0007] A speed regulating mechanism is provided between the feed shaft and the warp shaft, and a threaded pusher is connected to the mounting bracket to change the differential speed between the feed shaft and the warp shaft.

[0008] It also includes an elastic limiting member disposed on the mounting bracket and between the yarn feed shaft and the warp shaft. The elastic limiting member deforms due to changes in the winding diameter of the yarn on the warp shaft and acts on the threaded pusher.

[0009] As described above, the differential warping machine that does not require stopping: the elastic limiting component includes a support cylinder mounted on the mounting frame, a connecting rod slidably connected to one end of the support cylinder, and a limiting roller rotatably connected to the end of the connecting rod away from the support cylinder;

[0010] It also includes a spring, which is disposed inside the support cylinder. One end of the spring abuts against the connecting rod, and the other end abuts against the inner end of the support cylinder.

[0011] As described above, the differential warping machine that does not require stopping: when the connecting rod rotates relative to the support cylinder, the rolling balls on the connecting rod can squeeze the transmission shaft that is rotatably arranged along the axial direction of the support cylinder. One end of the transmission shaft is inserted into the inner groove formed by the connecting rod, and the transmission shaft is provided with a threaded groove that is adapted to slide with the rolling balls.

[0012] As described above, the non-stop differential warping machine includes a threaded pusher comprising a bidirectional lead screw rotatably mounted on the mounting frame. The bidirectional lead screw is connected to a connecting shaft rotatably mounted on the mounting frame via a belt, and the connecting shaft is connected to the transmission shaft via a bevel gear set.

[0013] It also includes symmetrically arranged threaded sleeves, which are arranged along the axial direction of the bidirectional lead screw and threadedly connected to the bidirectional lead screw, and the threaded sleeves are provided with compression blocks.

[0014] As described above, the non-stop differential warping machine includes a first transmission component and a second transmission component respectively sleeved on the feed shaft and the warp shaft, and the first transmission component and the second transmission component are connected by a speed regulating belt.

[0015] As described above, the differential warping machine that does not require stopping: the first transmission component includes symmetrically arranged driven wheels, the driven wheels are arranged along the axial direction of the wire feed shaft and are slidably connected to the wire feed shaft, and an annular groove is formed on the driven wheel to be rotatably connected to the extrusion block.

[0016] As described above, the differential warping machine that does not require stopping: the second transmission component includes a drive wheel that is symmetrically and rotatably arranged on the warp beam, and the rotation of the drive wheel is driven by a motor mounted on the mounting frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] During yarn feeding, the diameter of the yarn wound on the warp beam increases synchronously, changing the yarn tension between the feed beam and the warp beam. This pressure compresses the elastic limiting element, causing it to deform and act on the threaded pusher. The threaded pusher adjusts the transmission speed of the speed regulating mechanism, thus changing the rotational speed between the feed beam and the warp beam. During yarn feeding, the machine can continuously and automatically adjust the rotational speed of the feed beam without stopping, reducing it as the warp beam diameter changes, thereby maintaining a constant linear speed and avoiding uneven tension and yarn quality degradation caused by speed variations. Using yarn tension detection simplifies the control process, reduces reliance on complex equipment, and lowers warping costs and maintenance difficulty. Attached Figure Description

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-8 In this embodiment of the utility model, a differential warping machine that does not require stopping includes a mounting frame 1, on which a yarn feed shaft 2 and a warp shaft 3 are rotatably mounted in sequence along the yarn feeding direction;

[0032] A speed regulating mechanism is provided between the feed shaft 2 and the warp shaft 3, and a threaded pusher is connected to the mounting bracket 1 to change the differential speed between the feed shaft 2 and the warp shaft 3.

[0033] It also includes an elastic limiting member disposed on the mounting frame 1 and between the feed shaft 2 and the warp shaft 3. The elastic limiting member deforms due to the change in the winding diameter of the yarn on the warp shaft 3 and acts on the threaded pusher.

[0034] In this embodiment, when conveying the yarn, the feed shaft 2 and the warp shaft 3 are controlled to rotate simultaneously. At this time, the feed shaft 2 and the warp shaft 3 rotate at the same speed. As the conveying time increases, the diameter of the yarn wound on the warp shaft 3 increases synchronously. At this time, the tension of the yarn between the feed shaft 2 and the warp shaft 3 changes, thereby squeezing the elastic limiting member. The elastic limiting member deforms under pressure and acts on the threaded pusher. Under the adjustment of the threaded pusher, the transmission speed of the speed regulating mechanism can be changed, thereby changing the rotation speed between the feed shaft 2 and the warp shaft 3. During the yarn conveying process, the rotation speed of the feed shaft 2 can be continuously and automatically adjusted without stopping the machine, so that it decreases as the diameter of the warp shaft 3 changes, thereby maintaining a constant linear speed and avoiding uneven tension and yarn quality degradation caused by speed changes. By using the yarn tension detection method, the control process can be simplified, the dependence on complex equipment can be reduced, thereby reducing warping costs and maintenance difficulty.

[0035] For further solutions to this utility model, please refer to [link / reference]. Figure 3 and Figure 4The elastic limiting member includes a support cylinder 8 mounted on the mounting frame 1, a connecting rod 7 slidably connected to one end of the support cylinder 8, and a limiting roller 5 rotatably connected to the end of the connecting rod 7 away from the support cylinder 8;

[0036] It also includes a spring 9, which is disposed inside the support cylinder 8. One end of the spring 9 abuts against the connecting rod 7, and the other end abuts against the inner end of the support cylinder 8.

[0037] When the connecting rod 7 rotates relative to the support cylinder 8, the rolling balls 701 on the connecting rod 7 can squeeze the transmission shaft 10 which is rotatably arranged along the axial direction of the support cylinder 8. One end of the transmission shaft 10 is inserted into the inner groove formed by the connecting rod 7, and the transmission shaft 10 is provided with a threaded groove 1001 that is slidably adapted to the rolling balls 701.

[0038] Preferably, the presence of the limiting roller 5 serves to guide and limit the conveying of the yarn, effectively preventing the yarn from slipping during the conveying process, thereby improving the neatness and stability of the yarn bundle.

[0039] Specifically, when the yarn is being conveyed, as the diameter of the warp beam 3 increases, the friction between the limiting roller 5 and the warp beam 3 will also change accordingly, thus affecting the yarn tension. At this time, the limiting roller 5 is squeezed by the yarn, causing the spring 9 to be compressed again, further storing elastic potential energy. When the connecting rod 7 moves upward relative to the support cylinder 8, the ball bearing 701 in the connecting rod 7 squeezes the threaded groove 1001, causing the transmission shaft 10 to rotate relative to the support cylinder 8 under the tilting force. This achieves differential speed adjustment of the speed regulating mechanism that starts with changes in yarn tension, enabling real-time monitoring of yarn tension and ensuring that the yarn maintains a constant linear speed during the warping process.

[0040] It should be noted that the end of the limiting roller 5 is provided with a collar 6 that is slidably connected to the mounting frame 1, which is used to guide the movement of the limiting roller 5.

[0041] For further solutions to this utility model, please refer to [link / reference]. Figure 6 and Figure 7 The threaded pusher includes a bidirectional lead screw 14 rotatably mounted on the mounting frame 1. The bidirectional lead screw 14 is connected to a connecting shaft 12 rotatably mounted on the mounting frame 1 via a belt 13, and the connecting shaft 12 is connected to the transmission shaft 10 via a bevel gear set 11.

[0042] It also includes symmetrically arranged threaded sleeves 15, which are arranged along the axial direction of the bidirectional lead screw 14 and threadedly connected to the bidirectional lead screw 14, and are provided with pressing blocks 1501.

[0043] When the aforementioned drive shaft 10 rotates, it drives the connecting shaft 12 to rotate synchronously under the transmission of the bevel gear set 11. At this time, under the transmission of the belt 13, the double-acting screw 14 rotates, driving the two threaded sleeves 15 to move linearly along the axial direction of the double-acting screw 14 at the same time. The two threaded sleeves 15 rotate in opposite directions. The change in the position of the threaded sleeves 15 can act on the first transmission component, thereby realizing the differential speed adjustment between the first transmission component and the second transmission component.

[0044] For further solutions to this utility model, please refer to [link / reference]. Figure 7 and Figure 8 The speed regulating mechanism includes a first transmission component and a second transmission component respectively sleeved on the feed shaft 2 and the warp shaft 3, and the first transmission component and the second transmission component are connected by a speed regulating belt 18.

[0045] The first transmission component includes symmetrically arranged driven wheels 17, which are arranged along the axial direction of the feed shaft 2 and are slidably connected to the feed shaft 2. An annular groove 1701 is formed on the driven wheel 17, which is rotatably connected to the extrusion block 1501.

[0046] The second transmission component includes a drive wheel 16 symmetrically and rotatably mounted on the warp shaft 3, and the rotation of the drive wheel 16 is driven by a motor 4 mounted on the mounting bracket 1.

[0047] Preferably, at least one set of strip grooves is formed on the feed shaft 2, and a strip block 1702 that slides with the strip grooves is provided on the inner ring of the driven wheel 17. Under the constraint of the strip grooves and the strip block 1702, the driven wheel 17 and the feed shaft 2 are rotated together, and the rotation of the feed shaft 2 is not affected.

[0048] In the initial state, the distance between the speed regulating belt 18 and the axis of the transmission shaft 2 when it is sleeved between the two driven pulleys 17 is at its minimum, and the distance between the speed regulating belt 18 and the axis of the shaft 3 when it is sleeved between the two driving pulleys 16 is at its maximum. When the threaded sleeve 15 moves, under the pressure of the pressing block 1501, it drives the two driven pulleys 17 to move synchronously in a straight line along the axial direction of the transmission shaft 2. At this time, the distance between the two driven pulleys 17 decreases, and when the two driven pulleys 17 are relatively close, the inclined surface formed by the driven pulleys 17 exerts pressure on the speed regulating belt 18. The pressure causes the contact position between the speed regulating belt 18 and the driven wheel 17 to move in a direction parallel to the radial direction of the driven wheel 17, and further away from the axial direction. Meanwhile, the contact position between the speed regulating belt 18 and the driving wheel 16 moves in a direction parallel to the radial direction of the driving wheel 16, and closer to the axis. This changes the transmission ratio between the feed shaft 2 and the warp shaft 3. Through the change in yarn tension, the rotational speed of the feed shaft 2 can automatically decrease as the diameter of the warp shaft 3 changes, thereby maintaining a constant linear speed and avoiding uneven tension and yarn quality degradation caused by speed changes.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
