Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a yarn breakage joint guiding mechanism. Background Technology

[0002] The ring spinning frame is a crucial piece of equipment in the spinning process. It is responsible for drafting, twisting, and winding semi-finished roving or sliver into fine yarn bobbins. On the roving frame, the sliver is transformed into roving after drafting and twisting. The combing machine then combs the fibers to produce combed sliver. The carding machine combines the sliver and improves its structure through card drafting. Subsequently, the roving is further twisted on the ring spinning frame to produce fine yarn. The output and quality of fine yarn reflect the overall level of each stage of the spinning process. For ease of use, the yarn needs to be guided by a yarn guide device.

[0003] In the existing technology, during the process of twisting roving into fine yarn, yarn breakage sometimes occurs. After a yarn breakage occurs, production personnel need to reconnect the broken ends of the yarn. However, due to the softness of the yarn, when encountering some long threading holes, it is difficult for the yarn ends to pass through the threading holes smoothly and quickly to complete the splicing operation, resulting in a waste of time and effort and affecting production efficiency. Utility Model Content

[0004] In view of this, the present invention provides a broken yarn connector guiding mechanism, the purpose of which is to increase the guiding measures for broken yarn ends, so as to improve the convenience and speed of connecting broken yarn ends and save time in connecting broken yarn ends.

The locking member is disposed on the guide rod and is used to fix the yarn end. The guide rod is used to drive the yarn end through the threading hole. The guide rod has insertion holes on its opposite two side surfaces, and the two insertion holes are interconnected to form a cavity. The locking member includes a pressure plate and a winding shaft. The outer diameter of the pressure plate is larger than the inner diameter of the insertion hole, and the center of the central axis of the pressure plate is on the same straight line as the center of the insertion hole. One end of the winding shaft is fixed to the pressure plate, and the other end of the winding shaft is inserted into the cavity through the insertion hole.

[0007] As a preferred technical solution, the inner wall of the cavity is fitted to the outer surface of the winding shaft, and the inner wall of the cavity is provided with a plurality of ball bearings distributed along the length of the winding shaft, and the outer surface of the winding shaft is provided with fixing holes adapted to the ball bearings.

[0008] Furthermore, the length of the winding shaft is longer than the length of the cavity, and one end of the winding shaft inserted into the cavity extends to the outside of the guide rod.

[0009] Furthermore, it also includes a chassis, which is fixed to one end of the winding shaft that extends to the outside of the guide rod.

[0010] Furthermore, it also includes a cutting groove, which is formed on the guide rod and is located on the same plane as the snap-fit ​​component. The cutting groove is provided with a blade for cutting the yarn inside.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] In existing technology, yarn breakage occasionally occurs during the process of twisting roving into yarn, also known as yarn breakage. When yarn breakage occurs, production personnel must reconnect the broken ends of the yarn. However, due to the soft nature of the yarn, when faced with some longer threading holes, the yarn ends are difficult to pass through the holes smoothly and quickly to complete the splicing operation. This not only wastes valuable time and effort but also adversely affects production efficiency.

[0024] Therefore, in order to solve the above problems and improve the function of guiding broken yarn splices, this utility model discloses a broken yarn splice guiding mechanism, see reference. Figure 1 and Figure 2 The spinning machine is provided with a threading hole for yarn to pass through. The guiding mechanism includes a guide rod 1 and a locking member 2. The locking member 2 is located on the guide rod 1 and is used to fix the yarn end. The guide rod 1 is used to drive the yarn end through the threading hole. The guide rod 1 has insertion holes 7 on opposite sides. The two insertion holes 7 are interconnected to form a cavity 11. The locking member 2 includes a pressure plate 5 and a winding shaft 6. The outer diameter of the pressure plate 5 is larger than the inner diameter of the insertion hole 7, and the center of the central axis of the pressure plate 5 is on the same straight line as the center of the insertion hole 7. One end of the winding shaft 6 is fixed to the pressure plate 5, and the other end of the winding shaft 6 is inserted into the cavity 11 through the insertion hole 7.

[0025] In this embodiment, when the spinning machine experiences a yarn breakage, the user can first pull the broken yarn head out of the spinning machine, then wind the pulled-out yarn onto the winding shaft 6. After winding, press the pressure plate 5 to clamp the yarn between the pressure plate 5 and the guide rod 1. Finally, the user passes the guide rod 1 through the threading hole of the spinning machine, so that the yarn clamped on the guide rod 1 can be driven through the threading hole together to complete the yarn breakage splicing operation.

[0026] In a specific implementation, to improve the stability of the winding shaft 6 and the clamping stability of the yarn by the pressure plate 5, the inner wall of the cavity 11 is in contact with the outer surface of the winding shaft 6. The inner wall of the cavity 11 is provided with a plurality of ball bearings 10 distributed along the length of the winding shaft 6. The outer surface of the winding shaft 6 is provided with fixing holes 9 that are adapted to the ball bearings 10. With this arrangement, in the initial state, the ball bearings 10 are engaged in the fixing holes 9 to support the winding shaft 6. When the user presses the pressure plate 5, the winding shaft 6 will be forced to retract into the cavity 11. At this time, the ball bearings 10 located in the fixing holes 9 will be contracted due to the compression of the winding shaft 6 until they are disengaged from the fixing holes 9. As the winding shaft 6 continues to move, the fixing holes 9 will contact the ball bearings 10 at the position of the moving direction of the winding shaft 6 until the pressure plate 5 contacts the surface of the guide rod 1, at which point the ball bearing 10 at the current position will be re-engaged into the fixing holes 9.

[0027] It should be noted that the fixing hole 9 is located on the outer wall of the middle part of the winding shaft 6. The spacing between each bead 10 on the inner wall of the cavity 11 is equal. When the bead 10 furthest from the insertion hole 7 is inserted into the fixing hole 9, the pressure plate 5 is in contact with the surface of the guide rod 1.

[0028] It is understandable that the ball bearing 10 is a spring ball bearing, a common mechanical component, usually used to achieve functions such as positioning, fixing or connecting, which will not be elaborated on below.

[0029] Furthermore, to facilitate the reset of the pressure plate 5, the length of the winding shaft 6 is greater than the length of the cavity 11. One end of the winding shaft 6 inserted into the cavity 11 extends to the outside of the guide rod 1. It also includes a base 8, which is fixed to the end of the winding shaft 6 that extends to the outside of the guide rod 1. With this arrangement, when the user presses the pressure plate 5, the base 8 will move downward synchronously with the pressure plate 5. When the user needs to lift the pressure plate 5, the user can push the base 8 in the direction of the pressure plate 5. The movement of the base 8 drives the winding shaft 6 to move upward synchronously, thereby achieving the rapid reset of the pressure plate 5.

[0030] This design allows the pressure plate 5 to be immediately reset after the guide rod 1 passes through the threading hole to release the fixation of the yarn, facilitating yarn splicing and further improving the efficiency of yarn breakage splicing.

[0031] In another embodiment, the surface of the winding shaft 6 and the inner wall of the cavity 11 are both provided with matching threads. With this arrangement, when a broken yarn is wound on the winding shaft 6, the user can rotate the pressure plate 5 to make the winding shaft 6 screw into the cavity 11 until the pressure plate 5 squeezes the yarn onto the guide rod 1. After the yarn is led out of the threading hole, the yarn can be released by simply rotating the pressure plate 5 in the opposite direction.

[0032] At the same time, during the rotation of the winding shaft 6, the yarn can also be wound up, thereby reducing the slack of the yarn, increasing the tension of the yarn, and making it more stably fixed on the guide rod 1.

[0033] In this embodiment, a rubber pad is provided on the side of the pressure plate 5 facing the insertion hole 7. This arrangement can reduce the collision and wear between the pressure plate 5 and the surface of the guide rod 1. At the same time, due to the elasticity of the rubber sleeve, it can help fill the gap between the pressure plate 5 and the guide rod 1, which helps to improve the clamping effect on the yarn.

[0034] Example 2

[0035] Based on Embodiment 1, after the guide rod 1 guides the yarn through the threading hole, it is necessary to untie the yarn wrapped around the snap fastener 2. This is inconvenient when handling some finer yarns. Therefore, refer to... Figure 1 The present invention also includes a cutting groove 3 for cutting yarn ends. Specifically, it includes a cutting groove 3, which is formed on the guide rod 1 and is located on the same plane as the snap-fit ​​part 2. The cutting groove 3 is provided with a blade 4 for cutting yarn inside.

[0036] In this embodiment, with the above structure, after the guide rod 1 carries the yarn through the threading hole, the user can hold the guide rod 1 with one hand and pull the yarn straight towards the cutting groove 3 with the other hand, aligning the yarn with the blade 4 in the cutting groove 3. Then, the guide rod 1 is flipped so that the blade 4 moves towards the yarn until the blade 4 contacts the yarn. Since the yarn is in a straightened state, the blade 4 can smoothly cut the yarn under the action of inertia, completing the yarn end cutting work. This cuts off the yarn end wrapped in the snap fastener 2, saving the time of untying the yarn and helping to improve production efficiency.

[0037] Furthermore, since the cutting groove 3 and the locking element 2 are on the same plane, the yarn end can be accurately cut during the cutting process, avoiding tangling and knotting, and improving work efficiency. In addition, because the blade 4 is located inside the cutting groove 3, it helps prevent the user's fingers from touching the blade 4 during the cutting process, thus avoiding the risk of accidental injury.

[0038] The blade 4 has a clamp-like structure, which allows it to more stably hold the yarn during cutting, reducing the possibility of yarn slippage. The clamp-like blade 4 provides uniform shearing force during cutting, ensuring the yarn is cleanly cut while minimizing damage.

[0039] In summary, in conjunction with Embodiments 1 and 2, the working steps of the yarn breakage guide mechanism are as follows: First, when a yarn breakage occurs in the spinning machine, the operator can pull the broken yarn head out of the spinning machine to a certain length, ensuring that the length of the pulled-out yarn is sufficient for subsequent operations and will not cause excessive waste of yarn. Then, the pulled-out yarn is wound around the winding shaft 6.

[0040] Secondly, choose the method of fixing the yarn according to the actual situation. If the pressing plate 5 is used, after the yarn is wound, press the pressing plate 5. At this time, the winding shaft 6 is forced into the cavity 11, and the ball bearing 10 disengages from the fixing hole 9 until the pressing plate 5 contacts the surface of the guide rod 1 and the ball bearing 10 re-engages into the fixing hole 9, thus fixing the yarn. If the rotating pressing plate 5 is used, after the yarn is wound, rotate the pressing plate 5 to screw the winding shaft 6 into the cavity 11. At the same time, observe the tightness of the yarn and its distribution on the winding shaft 6 to ensure that the yarn is firmly squeezed on the guide rod 1 and maintains appropriate tension. After the yarn is fixed, the operator holds the guide rod 1, aligns it with the threading hole of the spinning machine, and passes the guide rod 1 through the threading hole.

[0041] Finally, after the guide rod 1 successfully passes through the threading hole, if the yarn was previously fixed by pressing the pressure plate 5, the base plate 8 is pushed to move the winding shaft 6 upward, quickly resetting the pressure plate 5 and releasing the yarn. If the yarn was previously fixed by rotating the pressure plate 5, the pressure plate 5 is rotated in the opposite direction to release the yarn. Afterward, the yarn is removed from the winding shaft 6 or directly spliced. During splicing, if it is difficult to untie the yarn from the winding shaft 6, the yarn is cut by the blade 4 in the cutting groove 3.
