Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a yarn feeding device and spinning equipment. Background Technology

[0002] Rotor spinning is a free-end spinning method. Its working principle utilizes the centrifugal force generated by the high-speed rotation of the spinning cup to dynamically cohede and twist the single fibers fed into the cup, ultimately outputting a stable continuous yarn. The yarn guide device, as the core execution unit that transports the yarn to the winding mechanism, directly affects the overall efficiency of the entire spinning system. In the rotor spinning equipment operating system, the yarn guide device, as a key functional module, is usually configured in an array. Current commissioning procedures generally involve first installing all yarn guide devices onto the main body of the equipment, and then calibrating the parameters of each unit's yarn guide device through a CNC platform. With the advancement of industrial upgrading, the large-scale application of spinning equipment with over 600 spindles has increasingly highlighted the efficiency bottleneck of this commissioning mode: on the one hand, the geometric increase in the number of modules leads to a longer commissioning cycle for the entire production line; on the other hand, when a single yarn guide module malfunctions, a disassembly-replacement-recalibration process is required, also extending the commissioning of the entire production line; severely restricting the equipment delivery cycle. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a yarn guiding device and spinning equipment that can improve the debugging efficiency of the yarn guiding device.

[0004] To solve the above-mentioned technical problems, this utility model provides a yarn feeding device, comprising: a support member connected to a detection member; a connecting frame hinged to the support member, the connecting frame being rotatably connected to a first rolling member; a sensing member connected to the connecting frame, the sensing member being movable to the detection position of the detection member; and a driving member, the detection member controlling the start of the driving member, the output end of the driving member being connected to a second rolling member, the first rolling member and the second rolling member forming a clamping space.

[0005] In one embodiment of this utility model, an elastic element is installed between the connecting frame and the support member. When the connecting frame rotates, the elastic element is compressed, and at the same time, the distance between the first rolling element and the second rolling element increases, and the sensing element moves away from the detection position of the detection element.

[0006] In one embodiment of this utility model, the support member is provided with a mounting hole, a connecting block is provided in the mounting hole, a boss is provided at the end of the connecting block, and the elastic member is sleeved on the boss and connected to the connecting block.

[0007] In one embodiment of the present invention, the diameter of the boss gradually decreases in the direction away from the connecting block, and the end of the boss is provided with a groove.

[0008] In one embodiment of the present invention, a handle is connected to one side of the connecting frame, and the end of the handle away from the connecting frame is bent toward the support member.

[0009] In one embodiment of the present invention, the sensing element is further connected to a support plate, the end of the support plate is connected to the connecting frame, and the sensing element is connected to the side of the support plate near the detection element.

[0010] In one embodiment of the present invention, the connecting frame is further connected to a mounting platform, and the first rolling element is rotatably connected to the end of the mounting platform away from the connecting frame, and the first rolling element is elastic.

[0011] In one embodiment of the present invention, the support member includes a protrusion, the connecting frame includes at least two mounting blocks, a rotating shaft is connected to the opposite side of the two mounting blocks, the rotating shaft passes through the protrusion and is rotatably connected to the protrusion, and the protrusion is located between the two mounting blocks.

[0012] In one embodiment of this utility model, there is a gap between the protrusion and the mounting block.

[0013] A spinning device includes the above-mentioned yarn guiding device, which constitutes a complete and independent module and can be installed and debugged independently.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The yarn guiding device and spinning equipment described in this utility model, through the hinged connection between the connecting frame and the support member, and the connection between the connecting frame and the sensing member and the first rolling member, allows the driving member to start working simultaneously with the rotation of the connecting frame. This increases the distance between the first and second rolling members, allowing the yarn to pass through, thereby reducing the debugging steps of the yarn guiding device and improving its debugging efficiency. The movement of the sensing member controls the start of the driving member, enabling the yarn guiding device to be debugged independently. This allows the yarn guiding device to be independently debugged externally before installation on the spinning equipment, improving the overall debugging efficiency of the yarn guiding device.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Example 1

[0024] Reference Figure 1 and Figure 2 As shown, a yarn feeding device of this utility model includes: a support member 1, wherein a detection member 3 is connected to the support member 1; a connecting frame 2, wherein the connecting frame 2 is hinged to the support member 1, and a first rolling member 23 is rotatably connected to the connecting frame 2; a sensing member 4, wherein the sensing member 4 is connected to the connecting frame 2, and the sensing member 4 can move to the detection position of the detection member 3; and a driving member 5, wherein the detection member 3 can control the start of the driving member 5, and a second rolling member 51 is connected to the output end of the driving member 5, wherein a clamping space is formed between the first rolling member 23 and the second rolling member 51.

[0025] In this embodiment of the yarn guiding device, rotating the connecting frame 2 moves the sensing element 4 away from the detection element 3, simultaneously increasing the distance between the first rolling element 23 and the second rolling element 51. At this point, the yarn passes between the first rolling element 23 and the second rolling element 51. Then, rotating the connecting frame 2 moves the sensing element 4 to the detection position of the detection element 3, where the yarn is clamped between the first rolling element 23 and the second rolling element 51. The driving element 5 drives the second rolling element 51 to rotate, thereby moving the yarn. Through the hinge between the connecting frame 2 and the support element 1, and the connection between the connecting frame 2 and the sensing element 4 and the first rolling element 23, the rotation of the connecting frame 2 enables the driving element 5 to start working while simultaneously increasing the distance between the first rolling element 23 and the second rolling element 51, allowing the yarn to pass through. This reduces the debugging steps of the yarn guiding device and improves its debugging efficiency. The movement of the sensor 4 controls the start of the drive 5, thereby enabling the yarn guiding device to be independently debugged. This allows the yarn guiding device to be independently debugged externally before being installed on the spinning equipment, thus improving the overall debugging efficiency of the yarn guiding device.

[0026] Reference Figure 3 and Figure 4 As shown, the connecting frame 2 is hinged to the support member 1. Specifically, the support member 1 includes a protrusion 13, and the connecting frame 2 includes at least two mounting blocks 25 arranged opposite each other on the side near the support member 1. In this embodiment, the connecting frame 2 includes two mounting blocks 25. A rotating shaft 24 is connected to the opposite side of the two mounting blocks 25. The rotating shaft 24 passes through the end of the protrusion 13 and is rotatably connected to the protrusion 13. The protrusion 13 is located between the two mounting blocks 25, and there is a gap between the protrusion 13 and the mounting blocks 25 to prevent the mounting blocks 25 from rubbing against the protrusion 13 during rotation, which would cause damage to the protrusion 13 and the mounting blocks 25.

[0027] The connecting frame 2 is also connected to an elastic element 22, which can be considered as a spring. The end of the elastic element 22 is connected to the support 1. Specifically, one end of the elastic element 22 is connected to the top side wall of the connecting frame 2. In its natural state, the elastic element 22 causes the first rolling element 23 to be tightly pressed against the second rolling element 51, while the sensing element 4 is located at the detection position of the detection element 3. The support 1 has a mounting hole corresponding to the position of the elastic element 22. A connecting block 11 is provided in the mounting hole, which can be considered as a pressure adjusting screw. The end of the elastic element 22 is located in the mounting hole, which can guide the stretching and compression of the elastic element 22. A boss 12 is provided at one end of the connecting block 11 near the connecting frame 2. The diameter of the boss 12 gradually decreases away from the connecting block 11, meaning the sidewall of the boss 12 is inclined. A groove is provided at the end of the boss 12. An elastic member 22 is fitted onto the boss 12 and abuts against the sidewall of the boss 12. The inclined sidewall of the boss 12 guides the connection between the elastic member 22 and the connecting block 11. The diameter of the boss 12 is slightly larger than the inner diameter of the elastic member 22, so that the elastic member 22 presses against the boss 12 after being fitted onto it, reducing the width of the groove and making the connection between the elastic member 22 and the connecting block 11 more stable. In another embodiment, one end of the elastic member 22 is connected to the bottom sidewall of the connecting frame 2.

[0028] A handle 21 is connected to the side of the connecting frame 2 away from the elastic element 22. The handle 21 extends away from the pivot 24, and the end of the handle 21 away from the connecting frame 2 bends towards the support element 1, i.e., the end of the handle 21 is arc-shaped, which makes it easier for the human hand to grip the handle 21 and prevents the handle 21 from slipping off the human hand. The handle 21 can also be engaged with an external clamping mechanism, and the movement of the external clamping mechanism drives the connecting frame 2 to rotate.

[0029] The connecting frame 2 is rotatably connected to a first rolling element 23. Specifically, the connecting frame 2 is also connected to an outwardly protruding mounting platform 26. The first rolling element 23 is rotatably connected to the end of the mounting platform 26 away from the connecting frame 2, and the central axis of the first rolling element 23 is parallel to the central axis of the rotating shaft 24. The first rolling element 23 can be regarded as a yarn guiding roller. The first rolling element 23 is elastic, that is, the outer side of the first rolling element 23 is made of a material with elastic deformation, thereby increasing the friction between the first rolling element 23 and the yarn and preventing the yarn from slipping.

[0030] The drive unit 5 can be considered as a motor. The support unit 1 has an installation space, and the drive unit 5 is located within the installation space and connected to the support unit 1. The output end of the drive unit 5 protrudes from the installation space. A detection element 3 is connected to one side of the support unit 1. The detection element 3 is connected to the support unit 1 by an internal hex screw. Specifically, the detection element 3 can be considered as a Hall sensor. The drive unit 5 is located on the support unit 1 on the side opposite to the detection element 3. The detection element 3 includes a first connection end 31 for connecting to an external control board, and the drive unit 5 includes a second connection end 52 for connecting to an external control board. The detection element 3 sends a signal to the external control board, and the external control board can send a signal to the drive unit 5, thereby controlling the opening of the drive unit.

[0031] The output end of the drive member 5 is connected to the second roller member 51, and the drive member 5 can drive the second roller member 51 to rotate. The second roller member 51 can be regarded as a yarn feeding roller. The center line of the second roller member 51 is parallel to the center line of the first roller member 23. The first roller member 23 and the second roller member 51 form a clamping space for clamping the yarn.

[0032] The sensing element 4 is used to cooperate with the detection element 3, and the sensing element 4 can be regarded as a magnetic steel body. The sensing element 4 is connected to the connecting frame 2. Specifically, the sensing element 4 is also connected to the support plate 41. The sensing element 4 is connected to the support plate 41 by countersunk screws. The end of the support plate 41 is connected to the side wall of the connecting frame 2 by semi-circular head screws. Since the plane of the side wall of the connecting frame 2 is perpendicular to the detection end of the detection element 3, the support plate 41 is twisted at 90°. The sensing element 4 is connected to the side of the support plate 41 close to the detection element 3, and the side of the support plate 41 connected to the sensing element 4 is parallel to the detection end of the detection element 3. The support plate 41 and the first rolling element 23 are both located below the rotating shaft 24. By rotating the connecting frame 2, the sensing element 4 can move to the detection position of the detection element 3, and the sensing element 4 can also move away from the detection position of the detection element 3. When the connecting frame 2 swings with the rotating shaft 24 as the fulcrum, the sensing element 4 located at the end of the support plate 41 can swing up and down with the connecting frame. The elastic element 22 uses the rotating shaft 24 as a fulcrum to make the first rolling element 23 apply pressure to the second rolling element 51, so that the yarn clamped between the first rolling element 23 and the second rolling element 51 can move in a set direction.

[0033] In use, pulling the handle 21 causes the connecting frame 2 to rotate, thereby compressing the elastic element 22. The support plate 41 rotates together with the connecting frame 2, and the sensing element 4 moves away from the detection position of the detection element 3. The control circuit of the yarn feeding device is in a ready state, and at the same time, the distance between the first rolling element 23 and the second rolling element 51 increases. At this time, the yarn is passed between the first rolling element 23 and the second rolling element 51. Then, pulling the handle 21 stops, the elastic element 22 rebounds and drives the connecting frame 2 to rotate, causing the sensing element 4 to move to the detection position of the detection element 3. The detection element 21 sends a signal to the control circuit of the yarn feeding device. At this time, the yarn is clamped between the first rolling element 23 and the second rolling element 51. The driving element 5 drives the second rolling element 51 to rotate, thereby driving the yarn to move in the set direction.

[0034] Example 2

[0035] This utility model also provides a spinning device, which includes the yarn guiding device in Embodiment 1. The yarn guiding device constitutes a complete and independent module, and the yarn guiding device can be installed and debugged independently.

[0036] This utility model discloses a yarn guiding device and spinning equipment. Through the hinged connection of the connecting frame 2 to the support member 1 and the connection of the connecting frame 2 to the sensing member 4 and the first rolling member 23, the rotation of the connecting frame 2 enables the driving member 5 to start working, while simultaneously increasing the distance between the first rolling member 23 and the second rolling member 51, allowing the yarn to pass through. This reduces the debugging steps of the yarn guiding device and improves its debugging efficiency. The movement of the sensing member 4 controls the activation of the driving member 5, allowing the yarn guiding device to be debugged independently. This enables the yarn guiding device to be independently debugged externally before installation on the spinning equipment, improving the overall debugging efficiency of the yarn guiding device. Furthermore, the overall structure of the yarn guiding device is simpler, the cost is lower, and the assembly speed of the spinning equipment is increased.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
