Description

Technical Field

[0001] The present application relates to the field of guide wheel mechanisms of texturing machines, and in particular to a yarn-stripping prevention guide wheel mechanism that can reset itself. Background Art

[0002] During the texturing process, POY (pre-oriented yarn) fibers first pass over the first roller and enter the first heating box for stretching, typically reaching a temperature of 150-200°C. They are then rapidly cooled to approximately 80°C by a cooling plate. The cooled fibers then enter the false twister, pass over the second roller, and then through the second heating box and third roller before being oiled and wound into DTY (draw-textured yarn).

[0003] To ensure the yarn moves along a predetermined route, guide wheel mechanisms are installed at various locations within the texturing machine. Several groups of guide wheel mechanisms work together to ensure the yarn moves along the predetermined route. During the operation of the texturing machine, the yarn is prone to falling off the guide wheel mechanisms. To address this, conventional techniques employ curved sidewalls within the guide wheel mechanisms. However, this approach is ineffective in preventing yarn from falling off. Furthermore, if yarn falls off, the machine must be shut down and the yarn manually placed back on the guide wheel. Failure to promptly detect the yarn falling off can disrupt normal operation. Utility Model Content

[0004] Therefore, it is necessary to provide a yarn-stripping prevention guide wheel mechanism that can be reset automatically, so as to solve the problem that the yarn-stripping prevention effect of the guide wheel mechanism in the prior art is not significant and requires manual reset.

[0005] To achieve the above-mentioned purpose, the inventor provides a self-resetting anti-yarn-stripping guide wheel mechanism, comprising:

[0006] guide wheel;

[0007] A yarn guide platform is provided adjacent to the guide wheel, and a side wall of the yarn guide platform is provided with a slope for allowing the yarn to move closer to the yarn guide platform;

[0008] An anti-slip baffle, located at one end of the yarn guide platform away from the guide wheel;

[0009] The yarn shifting rod is arranged at one end surface of the guide wheel close to the yarn guide platform and is located at the outer circumference of the guide wheel.

[0010] In some embodiments, further comprising:

[0011] The guide wheel, the yarn guide platform and the anti-slip baffle are all arranged on the installation shaft, and the guide wheel is rotatable.

[0012] In some embodiments, the anti-slip baffle is movably sleeved at the end of the mounting shaft and fixed by a positioning structure.

[0013] In some embodiments, the positioning structure includes a nut and a thread, the thread is provided on the side wall of the mounting shaft, and the nut is screwed onto the thread to clamp the anti-slip baffle.

[0014] In some embodiments, the length of the anti-slip baffle is greater than the radius of the guide wheel.

[0015] In some embodiments, the yarn guide platform is in the shape of a frustum.

[0016] In some embodiments, the anti-slip baffle is connected to the yarn guide platform as a whole, is movably sleeved on the end of the mounting shaft, and is fixed by a positioning structure.

[0017] In some embodiments, the yarn moving rod is tilted, and the tilting direction is the direction in which the yarn moves toward the side of the guide wheel.

[0018] In some embodiments, the side surface of the guide wheel is U-shaped.

[0019] In some embodiments, the radius of the guide wheel at one end away from the yarn guide table is greater than the radius of the guide wheel at one end close to the yarn guide table.

[0020] The yarn is then moved back to the guide wheel by the anti-slip plate, and the yarn is then automatically repositioned to prevent the yarn from falling off. The yarn is then automatically repositioned to prevent the yarn from falling off without manual inspection, thereby ensuring smooth operation.

For example, the "connection" can be a fixed connection, a detachable connection, or an integrated setting; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art of the present application, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] During the texturing process, POY (pre-oriented yarn) fibers first pass over the first roller and enter the first heating box for stretching, typically reaching a temperature of 150-200°C. They are then rapidly cooled to approximately 80°C by a cooling plate. The cooled fibers then enter the false twister, pass over the second roller, and then through the second heating box and third roller before being oiled and wound into DTY (draw-textured yarn).

[0047] To ensure the yarn moves along a predetermined route, guide wheel mechanisms are installed at various locations within the texturing machine. Several groups of guide wheel mechanisms work together to ensure the yarn moves along the predetermined route. During the operation of the texturing machine, the yarn is prone to falling off the guide wheel mechanisms. To address this, conventional techniques employ curved sidewalls within the guide wheel mechanisms. However, this approach is ineffective in preventing yarn from falling off. Furthermore, if yarn falls off, the machine must be shut down and the yarn manually placed back on the guide wheel. Failure to promptly detect the yarn falling off can disrupt normal operation.

[0048] To this end, the utility model provides a self-resetting anti-yarn-stripping guide wheel mechanism, which can be used in particular in a texturing machine to move the yarn along a preset route. It can achieve the goal of self-resetting the yarn in time to prevent it from falling off without the need for manual inspection, thereby ensuring smooth operation, thereby solving the problem in the prior art that the guide wheel mechanism has no significant anti-yarn-stripping effect and requires manual resetting.

[0049] See also Figure 1 and Figure 2In a specific embodiment, the self-resetting anti-yarn-stripping guide wheel mechanism includes a guide wheel 1, a yarn guide platform 2, an anti-stripping baffle 3, and a yarn shifting rod 4; the yarn guide platform 2 is arranged adjacent to the guide wheel 1, and one end face of the yarn guide platform 2 is close to one end face of the guide wheel 1, and the side wall of the yarn guide platform 2 is provided with a slope that allows the yarn to move closer to the yarn guide platform 2, that is, the slope is inclined to the axis of the guide wheel 1, and the slope is close to the guide wheel 1. The end is the slope, and the end away from the guide wheel 1 is the top of the slope; the anti-stripping baffle 3 is located at the end of the yarn guide platform 2 away from the guide wheel 1, that is, the guide wheel 1 and the anti-stripping baffle 3 are respectively located at the two ends of the yarn guide platform 2, and the yarn guide platform 2 is located between the guide wheel 1 and the anti-stripping baffle 3; the yarn shifting rod 4 is arranged at one end face of the guide wheel 1 close to the yarn guide platform 2, and is located at the outer circumference of the guide wheel 1.

[0050] The yarn-stripping prevention guide wheel mechanism that can be reset automatically is provided with an anti-stripping baffle 3, a yarn guide platform 2 and a yarn-pulling rod 4, and the side wall of the yarn guide platform 2 is provided with a slope that allows the yarn to move close to the yarn guide platform 2. The yarn-pulling rod 4 is located at the outer circumference of the guide wheel 1, so that when the yarn falls off the guide wheel 1, it will be blocked by the anti-stripping baffle 3 and then transferred to the yarn guide platform 2. Then the yarn can move along the slope of the yarn guide platform 2 to one side of the guide wheel 1, that is, the yarn can move close to the guide wheel 1 under the action of the slope of the yarn guide platform 2, and finally the rotation of the yarn-pulling rod drives the fallen yarn back to the guide wheel 1. Therefore, the yarn that falls off from the guide wheel 1 can be reset to the guide wheel 1 autonomously at the first time, so as to achieve the purpose of preventing the yarn from falling off. There is no need for manual inspection, and the yarn can be reset autonomously in time to achieve anti-falling and ensure smooth operation.

[0051] In some embodiments, the self-resetting anti-yarn-stripping guide wheel mechanism also includes a mounting shaft 5, which is used to be installed on the frame of the texturizing machine. The guide wheel 1, the yarn guide platform 2 and the anti-stripping baffle 3 are all arranged on the mounting shaft 5, and the guide wheel 1 is rotatable.

[0052] See also Figure 1 The yarn guide platform 2, the anti-slip baffle 3 and the yarn moving rod 4 together constitute an anti-slip reset component, which can be provided with only one group of anti-slip reset components, which is provided at the end of the guide wheel 1 facing away from the texturing machine frame. If the yarn falls off from the end of the guide wheel 1 facing away from the texturing machine frame, it can be reset automatically. In a further embodiment, the anti-slip reset component is provided with two groups, one group is provided at the end of the guide wheel 1 facing away from the texturing machine frame, and the other group is provided at the end of the guide wheel 1 facing toward the texturing machine frame. No matter the yarn falls off from the end of the guide wheel 1 facing away from the texturing machine frame or from the end of the guide wheel 1 facing toward the texturing machine frame, it can be reset automatically.

[0053] In a further embodiment, the guide wheel 1 is mounted on the mounting shaft 5 through a bearing 6, so that the guide wheel 1 can rotate relative to the mounting shaft 5. During the process of the yarn being pulled, the guide wheel 1 can rotate with the movement of the yarn to reduce the friction between the yarn and the guide wheel 1.

[0054] In a further embodiment, the yarn guide platform 2 may be rotatably disposed on the mounting shaft 5 , or may be non-rotatably disposed on the mounting shaft 5 .

[0055] Since the texturing machine requires several guide wheel 1 mechanisms to guide the movement of the yarn at different positions, the routes of the yarn guided by the guide wheel 1 mechanisms at different positions are also different. Therefore, in some embodiments, the anti-slip baffle 3 is movably sleeved at the end of the mounting shaft 5 and fixed by a positioning structure. The user can rotate the anti-slip baffle 3 relative to the mounting shaft 5 according to different usage positions to adjust the direction of the anti-slip baffle 3 to adapt to the direction in which the yarn will fall off at the corresponding usage position, and then lock the direction of the anti-slip baffle 3 through the positioning structure.

[0056] There can be multiple types of positioning structures. In some embodiments, the positioning structure can be screws and screw holes. The screw holes are provided at the end face of the mounting shaft 5. The anti-slip baffle 3 is installed at the end face of the mounting shaft 5 by screws. After adjusting the direction of the anti-slip baffle 3, the screws are tightened to lock the direction of the anti-slip baffle 3. When the direction of the anti-slip baffle 3 needs to be adjusted, the screws only need to be loosened.

[0057] See also Figure 1 or Figure 2 In other embodiments, the anti-slip baffle 3 is provided with a mounting hole, and the anti-slip baffle 3 is passed through the mounting hole to the mounting shaft 5; the positioning structure includes a nut 7 and a thread, and the thread is provided at the side wall of the mounting shaft 5, and the nut 7 is screwed on the thread to clamp the anti-slip baffle 3, that is, the anti-slip baffle 3 is clamped between the nut 7 and the yarn guide platform 2 through the nut 7 to limit the rotation of the anti-slip baffle 3. When the direction of the anti-slip baffle 3 needs to be adjusted, it is only necessary to loosen the nut 7.

[0058] Since the yarns guided by the guide wheel mechanisms at different positions have different routes, the yarns may be tilted, vertical or horizontal. In order to ensure that the yarns do not escape from the anti-slip baffle 3, in some embodiments, the length of the anti-slip baffle 3 is greater than the radius of the guide wheel 1, so that the yarns can be prevented from escaping as much as possible.

[0059] In some embodiments, the yarn guide 2 is a protrusion with a slope that allows the yarn to move closer to the yarn guide 2, that is, a protrusion with a slope. The protrusion can be a protrusion of any shape with a slope that allows the yarn to move closer to the yarn guide 2. In order to adapt to yarns of various directions, please refer to Figure 3In some embodiments, the yarn guide platform 2 is in a frustum-shaped form, and the frustum-shaped yarn guide platform 2 can guide the yarn to move in an inclined, horizontal or vertical direction.

[0060] See also Figure 3 In a further embodiment, the truncated cone-shaped yarn guide platform 2 is also provided with a mounting shaft 5 , and the truncated cone-shaped yarn guide platform 2 is inserted into the mounting shaft 5 through the mounting shaft 5 .

[0061] See also Figure 4 In a further embodiment, the anti-slip baffle 3 is connected to the truncated cone-shaped yarn guide platform 2 as a whole, and is movably sleeved on the end of the mounting shaft 5, that is, the mounting hole passes through the anti-slip baffle 3 and the yarn guide platform 2 that are connected as a whole, so that there will be no gap between the anti-slip baffle 3 and the yarn guide platform 2, and the fallen yarn will not be stuck in the gap between the two. In the process of moving the yarn to the guide wheel 1, it will also be quickly moved to the guide wheel 1 by the yarn moving rod 4.

[0062] Similarly, in order to adjust the direction of the anti-slip baffle 3, the anti-slip baffle 3 and the yarn guide platform 2 connected as one are fixed together by a positioning structure. If the positioning structure includes a nut 7 and a thread, the nut 7 is screwed on the thread to clamp the anti-slip baffle 3 and the yarn guide platform 2 together between the nut 7 and the guide wheel 1 to limit the rotation of the anti-slip baffle 3. When the direction of the anti-slip baffle 3 needs to be adjusted, just loosen the nut 7.

[0063] See also Figure 5 In some embodiments, the yarn shifting rod 4 is tilted, and the tilting direction is the direction in which the yarn moves toward the side of the guide wheel 1, that is, the tilting direction is tilted toward the direction away from the axis of the guide wheel 1. This setting allows the yarn to be picked up by the yarn shifting rod 4 and then slide back onto the guide wheel 1 along the tilting direction of the yarn shifting rod 4.

[0064] See also Figure 5 In some embodiments, the side surface of the guide wheel 1 is U-shaped, that is, the guide wheel 1 itself has the function of reducing the possibility of yarn coming out, which can avoid yarn coming out to a greater extent.

[0065] If there is only one set of anti-drop reset components, and this set of anti-drop reset components is located at the end of the guide wheel 1 facing away from the texturizing machine frame, please refer to Figure 5 In some embodiments, the radius of the guide wheel 1 at the end away from the yarn guide platform 2 is larger than the radius of the guide wheel 1 at the end close to the yarn guide platform 2. This can greatly reduce the possibility of the yarn escaping from the end of the guide wheel 1 away from the yarn guide platform 2.

[0066] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
