Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a roller device for a twisting machine. Background Technology

[0002] The roller is a key component of the twisting machine, playing a role in pulling, gathering, and merging the yarn. It is the main power source for the movement of the monofilaments during the twisting process. The power unit of the twisting machine drives the roller to rotate, and the monofilaments to be twisted on the yarn frame are pulled, gathered, and merged together by the roller. Then, they are fed into the rotating spindle and twisted into strands of a certain twist. Since the movement of the yarn does not require a large traction force, and in order to improve production efficiency, a twisting machine usually has multiple twisting units moving simultaneously. Each twisting unit has at least one roller, and the rollers of each twisting unit are connected to the power unit through a common transmission device.

[0003] In existing technology, the roller drive mechanism typically consists of two parallel drive rollers linked to the entire machine. Therefore, when a twisting unit experiences a breakage, entanglement, or other malfunction, the operator must patrol the area to identify the problem and manually disengage the roller from the drive roller to resolve the issue, before manually reconnecting it to resume operation. During this process, the drive rollers rotate continuously, posing a significant safety risk by catching the operator's arms or other body parts in the rollers. Furthermore, the long operation time from identifying the malfunction to manually disengaging the roller reduces production efficiency.

[0004] Therefore, there is an urgent need for a roller device for twisting machines that can achieve independent start-stop, further improve operational safety, and increase production efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a roller device for a twisting machine that can be started and stopped independently without requiring the operator to manually disengage the roller from the drive roller, thereby solving the problems of low operational safety and low production efficiency in the prior art.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A roller device for a twisting machine includes a support housing, a drive shaft rotatably connected to the support housing, and a winding roller, a magnetic core coil, an armature, an elastic element, and a drive wheel coaxially arranged on the drive shaft in sequence.

[0008] The winding roller and the magnetic core coil are fixedly connected to the drive shaft. The armature is rotatably connected to the drive shaft and can slide relative to it along the axial direction. The drive wheel is rotatably connected to the drive shaft and is connected to the power device. The elastic element is disposed between the armature and the drive wheel to provide an elastic force that moves the armature away from the magnetic core coil, so that a gap is maintained between the armature and the magnetic core coil when not in operation.

[0009] Furthermore, the elastic element is a leaf spring, with its two ends fixedly connected to the armature and the transmission wheel, respectively.

[0010] Furthermore, the magnetic core coil is connected to an independent power supply circuit.

[0011] Furthermore, the transmission wheel is a gear, and the roller device also includes a first gear and a second gear. The first gear is coaxially and fixedly connected to the output shaft of the power device, and the first gear, the second gear, and the transmission wheel are meshed together in sequence.

[0012] Furthermore, it also includes a wire-distributing wheel and a wire-leading wheel disposed on the same side of the outside of the support housing as the winding roller, with the winding roller as the center, the wire-distributing wheel and the wire-leading wheel being located on the radial sides of the winding roller respectively.

[0013] Furthermore, the axis of the dividing wheel is parallel to the axis of the winding roller, and the dividing wheel is provided with no less than two wire grooves along its axial direction.

[0014] Furthermore, the dividing wheel is provided with a first wire groove, a second wire groove, and a third wire groove evenly along the axial direction.

[0015] Furthermore, the diameter of the winding roller is three times the diameter of the dividing wheel.

[0016] Furthermore, the guide wheel includes a first guide wheel and a second guide wheel spaced apart on the same side of the winding roller. The axes of the first guide wheel and the second guide wheel are both parallel to the axis of the winding roller and are in the vertical direction. The center of the first guide wheel is higher than the center of the winding roller, and the center of the winding roller is higher than the center of the second guide wheel.

[0017] The roller device for a twisting machine provided in the embodiments of this application has at least the following beneficial effects:

[0018] This application achieves clutch transmission by setting up a magnetic core coil and an armature. By connecting the magnetic core coil to an independent power supply circuit, it achieves single-spindle single-control, allowing the start and stop of a single roller device to be controlled independently without stopping the entire machine, thereby improving fault handling efficiency and operational safety.

[0019] Furthermore, the flexible element allows the armature to quickly reset after power failure, instantly cutting off the power transmission. This eliminates the inertial delay problem caused by mechanical disengagement, reduces waste wire tangled due to inertia, saves costs, and improves the production efficiency of the twisting machine.

[0030] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components.

[0031] This utility model provides, for example Figures 1-4 The roller device for a twisting machine shown includes a support housing 2, a drive shaft 3 rotatably connected to the support housing 2, and a winding roller 1, a magnetic core coil 7, an armature 6, an elastic element 5 and a drive wheel 4 coaxially arranged on the drive shaft 3 in sequence.

[0032] The winding roller 1 is fixed to one end of the drive shaft 3 extending outside the support housing 2 and rotates synchronously with the drive shaft 3. It is used to pull the yarn and provide the traction force required for twisting. The magnetic core coil 7 is fixedly connected to the drive shaft 3 inside the support housing 2. The presence or absence of its magnetism can be achieved by controlling the on and off of the magnetic core coil 7. The armature 6 is rotatably connected to the drive shaft 3 and can slide relative to it along the axial direction. When the magnetic core coil 7 is energized and generates magnetism, the armature 6 can be attracted to the magnetic core coil 7 and move towards it. When the power is off, it is reset under the action of the elastic element 5. The drive wheel 4 is rotatably connected to the drive shaft 3 and is connected to the power device. The elastic element 5 is disposed between the armature 6 and the drive wheel 4. Its two ends are fixedly connected to the armature 6 and the drive wheel 4 respectively to provide an elastic force that moves the armature 6 away from the magnetic core coil 7, so that a gap is maintained between the armature 6 and the magnetic core coil 7 when not in operation.

[0033] Preferably, such as Figure 3 As shown, the elastic element 5 is a plate spring, with its two ends fixedly connected to the armature 6 and the transmission wheel 4, respectively. The elastic element 5 is located between the armature 6 and the transmission wheel 4. When the transmission wheel 4 rotates and the magnetic core coil 7 is de-energized, the tension generated by the contraction of the elastic element 5 can cause the armature 6 to slide away from the magnetic core coil 7 along the axial direction, interrupting the power transmission and causing the winding roller 1 to stop rotating immediately. This ensures that when the elastic element 5 recovers its contraction after the magnetic core coil 7 is de-energized, it can quickly pull the armature 6 away from the magnetic core coil 7, stopping the rotation of the winding roller 1 caused by the mechanical inertia generated by friction, thus reducing the production cost caused by inertia.

[0034] Furthermore, the magnetic core coil 7 is sleeved on the transmission shaft 3 inside the support housing 2 and is fixedly connected to the transmission shaft 3. This is a conventional structure known in the art, such as including a coil and an iron core structure. No specific limitation is made here, as long as it can generate magnetism after being energized to attract the armature 6.

[0035] Preferably, the magnetic core coil 7 is connected to an independent power supply circuit (not shown in the figure), and its magnetism can be controlled by switching the power on and off, thereby realizing single-spindle single-control of the twisting machine.

[0036] Preferably, such as Figure 4 As shown, the transmission wheel 4 is a gear, and the roller device also includes a first gear 10 and a second gear 11. The first gear 10 is coaxially fixedly connected to the output shaft 15 of the power device (such as a motor, not shown in the figure). The first gear 10, the second gear 11 and the transmission wheel 4 are meshed and connected in sequence.

[0037] Furthermore, the first gear 10, the second gear 11, and the transmission wheel 4 are all located inside the support housing 2. When the twisting machine power unit is started, the output shaft 15 rotates, driving the first gear 10 to rotate, which in turn drives the second gear 11 meshing with it and the transmission wheel 4 meshing with the second gear to rotate. Through gear meshing, efficient and stable power transmission is achieved, avoiding external interference and extending the service life of the components.

[0038] Preferably, such as Figure 2 As shown, the orderly traction and splitting of the yarn is achieved. The roller device for the twisting machine also includes a splitting wheel 12 and a guide wheel. The splitting wheel 12 and the guide wheel are both located on the same side outside the support housing 2 as the winding roller 1, and with the winding roller 1 as the center, the splitting wheel 12 and the guide wheel are located on the radial sides of the winding roller 1 respectively.

[0039] Furthermore, the guide wheel includes a first guide wheel 13 and a second guide wheel 14 spaced apart on the same side of the winding roller 1. The axes of the first guide wheel 13 and the second guide wheel 14 are parallel to the axis of the winding roller 1 and are in the vertical direction. The center of the first guide wheel 13 is higher than the center of the winding roller 1, and the center of the winding roller 1 is higher than the center of the second guide wheel 14.

[0040] Furthermore, the axis of the dividing wheel 12 is parallel to the axis of the winding roller 1, and the dividing wheel 12 is provided with no less than two guide grooves along its axial direction; preferably, the dividing wheel 12 is provided with a first guide groove 121, a second guide groove 122, and a third guide groove 123 evenly along its axial direction. During operation, the yarn is introduced by the first guide wheel 13, enters the first guide groove 121, winds half a turn on the first guide groove 121, is led out, winds more than half a turn on the winding roller 1, returns to the second guide groove 122, is led out again, winds on the winding roller 1, is led out from above the winding roller 1, goes to the third guide groove 123, winds around below the winding roller 1, and then passes through the second guide wheel 14 to the spindle for twisting. The arrangement of multiple guide grooves allows the yarn to wind on the winding roller 1 at a certain interval, providing sufficient contact area between the winding roller 1 and the yarn, thus providing sufficient friction to drive the yarn movement.

[0041] Preferably, the diameter of the winding roller 1 is three times the diameter of the dividing wheel 12, and the winding speed of the yarn on the dividing wheel 12 is one-third of the winding speed of the yarn on the winding roller 1. This allows for good control of the yarn winding speed and the twisting degree of the yarn in the twisting machine. The longer length of the yarn wound on the winding roller 1 increases the winding time of the yarn in the roller device, further improving the friction between the winding roller 1 and the yarn.

[0042] The working process of the roller device for a twisting machine provided by this utility model is as follows:

[0043] When the device is started, the output shaft 15 of the power unit rotates, which drives the first gear 10, which is fixed on the same axis, to rotate; the first gear 10 meshes with the second gear 11, driving the second gear 11 to rotate; the second gear 11 then meshes with the transmission wheel 4, driving the transmission wheel 4 to rotate.

[0044] At the same time, the independent power supply circuit of the magnetic core coil 7 is energized, the coil generates magnetism, attracts the armature 6 to move along the drive shaft 3 to the magnetic core coil 7, at which time the elastic element 5 is stretched and deformed; when the armature 6 and the magnetic core coil 7 are tightly attracted, the power of the drive wheel 4 is transmitted to the magnetic core coil 7 through the armature 6, which in turn drives the drive shaft 3, which is fixedly connected to the magnetic core coil 7, to rotate, and finally drives the winding roller 1 to rotate synchronously.

[0045] The yarn is introduced through the first guide wheel 13, and passes through the first guide groove 121, the surface of the winding roller 1, the second guide groove 122, the surface of the winding roller 1, and the third guide groove 123 of the splitting wheel 12 in sequence, forming a multi-segment winding path of the yarn. It obtains sufficient frictional traction on the surface of the winding roller 1, and finally is led out to the spindle through the second guide wheel 14 to complete the twisting.

[0046] When a twisting unit malfunctions (such as a broken end or tangling), the independent power supply circuit of the magnetic core coil 7 is de-energized, and the magnetic core coil 7 loses its magnetism. At this time, the stretched elastic element 5 returns to its original position and contracts, and the resulting elastic force instantly pulls the armature 6 away from the magnetic core coil 7. The power transmission path is interrupted, and the transmission shaft 3 and the winding roller 1 immediately stop rotating, thus avoiding unnecessary rotation caused by the mechanical inertia generated by friction between the magnetic core coil 7 and the armature 6.

[0047] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
