Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a bobbin clamping mechanism and a texturing machine. Background Technology

[0002] On a manual texturing machine, the bobbin held between two clamping discs needs to be changed manually. Generally, at least one clamping disc is rotatably connected to the base. When the bobbin needs to be replaced, the rotating arm with one of the clamping discs can be manually turned slightly, causing it to rotate around the base at a certain angle. This increases the distance between the two clamping discs, allowing the bobbin to be replaced. Afterward, the rotating arm with the clamping disc is reset, and the two clamping discs will hold the bobbin.

[0003] However, there are slight variations in the length of each bobbin, especially for paper bobbins. Furthermore, environmental factors, particularly humidity, can further increase these variations. When such a bobbin is installed between two clamps, the axis of at least one clamp will be slightly off-center from the axis of the bobbin, causing the axes of the two clamps to be misaligned. This can lead to excessive vibration of the yarn cake during the winding of the chemical fiber filaments, consequently affecting the forming quality and the lifespan of the bearings between the clamps and the rotating arm. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a tube clamping mechanism and a texturing machine, which can solve the problem that the axis of the clamp may be different due to the inconsistent length of the tube.

[0005] The specific technical solution of this utility model embodiment is as follows:

[0006] A tube clamping mechanism, the tube clamping mechanism comprising:

[0007] The tube rack includes a first arm and a second arm arranged opposite to each other;

[0008] A displacement mechanism is connected to the first arm, and a rotatable first clamping plate is connected to the displacement mechanism. The displacement mechanism can drive the first clamping plate to move along its own axis.

[0009] A rotatable second clamping plate connected to the second arm is used to install a tube between the first clamping plate and the second clamping plate. During the movement of the first clamping plate along its own axis, the axis of the first clamping plate and the axis of the second clamping plate are on the same straight line.

[0010] Preferably, the first clamp has a first position and a second position. In the first position, the first clamp and the second clamp can clamp the tube. In the second position, the tube can be installed between the first clamp and the second clamp or removed from between the first clamp and the second clamp. In the first position, the distance between the first clamp and the second clamp is smaller than the distance between the first clamp and the second clamp in the second position.

[0011] Preferably, the first arm and the second arm remain fixed relative to each other.

[0012] Preferably, the tube clamping mechanism further includes:

[0013] A driving mechanism is provided to drive the displacement mechanism to move at least a portion of the displacement mechanism along the axial direction of the first clamp.

[0014] Preferably, the displacement mechanism includes: a base mechanism, a moving member, and an elastic member. The base mechanism is connected to the first arm, and the moving member is connected to the first clamping plate via a first bearing. The moving member is capable of moving relative to the base mechanism along the axial direction of the first clamping plate to drive the first clamping plate to move along its own axial direction. The elastic member is provided between the base mechanism and the moving member, and the elastic member allows the moving member to keep the first clamping plate in the first position.

[0015] Preferably, an inflation space can be formed between the base mechanism and the moving part; the displacement mechanism includes a gas port communicating with the inflation space; the drive mechanism includes a gas supply line with a switching unit, the gas supply line being connected to the gas port.

[0016] When the inflation space is filled with gas, the moving member overcomes the force of the elastic member and moves relative to the base mechanism along the axial direction of the first clamping plate, so that the first clamping plate moves from the first position to the second position.

[0017] Preferably, the base mechanism includes a rod extending along the axial direction of the first clamping plate, the movable member being slidably sleeved on the rod, one end of the elastic member abutting or connecting to the base mechanism, and the other end of the elastic member abutting or connecting to the movable member, the elastic member causing the movable member to have a tendency to move towards the tube; when the inflation space is filled with gas, the gas causes the movable member to overcome the force of the elastic member and have a tendency to move away from the tube.

[0018] Preferably, the first arm has an opening, the axis of which is parallel to or on the same straight line as the axis of the first chuck; the displacement mechanism includes a spindle installed in the opening and capable of sliding along the axis of the opening, the spindle being connected to the first chuck via a first bearing;

[0019] The driving mechanism includes: a rotating arm rotatably connected to the bobbin holder; when the rotating arm rotates away from the bobbin, it can drive the mandrel to move away from the bobbin, so that the first chuck moves from the first position to the second position; when the rotating arm rotates towards the bobbin, it can drive the mandrel to move towards the bobbin, so that the first chuck moves from the second position to the first position.

[0020] Preferably, an elastic element is provided between the first arm and the rotating arm, the elastic element causing the rotating arm to have a tendency to rotate toward the tube;

[0021] A linkage is connected to the rotating arm, which can drive the mandrel to slide along the axial direction of the opening; the linkage and the rotating arm can generate displacement in the radial direction of the rotation of the rotating arm, or the linkage and the mandrel can generate displacement in the radial direction of the rotation of the rotating arm.

[0022] A texturing machine, the texturing machine comprising a tube clamping mechanism as described in any of the above.

[0023] The technical solution of this utility model has the following significant beneficial effects:

[0024] In this application, when the tube clamping mechanism drives the first clamping plate to move away from the tube along its own axis, the tube can be installed between the first clamping plate and the second clamping plate or removed from between the first clamping plate and the second clamping plate. When the first clamping plate is driven to move closer to the tube along its own axis by the displacement mechanism, the tube between the first clamping plate and the second clamping plate can be clamped. When there is a difference in the length of the bobbin, the displacement mechanism can drive the first clamp to move along its own axis, thereby adjusting the position of the first clamp to compensate for the difference in bobbin length. During the above compensation process, since the displacement mechanism drives the first clamp to move along its own axis, the axis of the first clamp is always on the same straight line as the axis of the second clamp. The rotation axis of the installed bobbin is also on this straight line. Therefore, the problem of the first clamp and the second clamp having different axes is completely avoided, which greatly reduces the vibration of the yarn cake caused by the bobbin winding chemical fiber filaments, ensures the forming quality, and greatly improves the service life of the first clamp, the bearings between the first clamp and the displacement mechanism, and other components.

[0041] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0042] To address the issue of misalignment of the clamping disc axis due to inconsistent tube lengths, this application proposes a tube clamping mechanism, such as... Figures 1 to 13 As shown, the tube clamping mechanism may include: a tube frame 1, including a first arm 11 and a second arm 12 arranged opposite to each other; a displacement mechanism 2 connected to the first arm 11, a first clamping plate 3 connected to the displacement mechanism 2, the displacement mechanism 2 being able to drive the first clamping plate 3 to move along its own axis; and a second clamping plate 5 connected to the second arm 12, used to install a tube 6 between the first clamping plate 3 and the second clamping plate 5, wherein during the movement of the first clamping plate 3 along its own axis, the axis of the first clamping plate 3 and the axis of the second clamping plate 5 are on the same straight line.

[0043] In this application, when the cylinder clamping mechanism drives the first clamping plate 3 to move away from the cylinder 6 along its own axis direction through the displacement mechanism 2, the cylinder 6 can be installed between the first clamping plate 3 and the second clamping plate 5 or removed from the first clamping plate 3 and the second clamping plate 5; when the first clamping plate 3 is driven by the displacement mechanism 2 to move closer to the cylinder 6 along its own axis direction, the cylinder 6 between the first clamping plate 3 and the second clamping plate 5 can be clamped. When the length of the bobbin 6 differs, the displacement mechanism 2 can drive the first clamping plate 3 to move along its own axis, thereby adjusting the position of the first clamping plate 3 to compensate for the difference in the length of the bobbin 6. During the above compensation process, since the displacement mechanism 2 drives the first clamping plate 3 to move along its own axis, the axis of the first clamping plate 3 is always on the same straight line as the axis of the second clamping plate 5. The rotation axis of the installed bobbin 6 is also on this straight line. Therefore, the problem of the first clamping plate 3 and the second clamping plate 5 having different axes is completely avoided, which greatly reduces the vibration of the yarn cake caused by the bobbin 6 winding chemical fiber filaments, ensures the forming quality, and greatly improves the service life of the first clamping plate 3, the bearings between the first clamping plate 3 and the displacement mechanism 2, and other components.

[0044] like Figure 1 , Figure 2 and Figure 9As shown, the bobbin clamping mechanism may include: a bobbin holder 1, a displacement mechanism 2, a first clamping plate 3, and a second clamping plate 5. The bobbin holder 1 includes a first arm 11 and a second arm 12 arranged opposite each other. The bobbin holder 1 may also include a connecting portion 13 connecting the first arm 11 and the second arm 12. The extending direction of the connecting portion 13 is the same as the extending direction of the bobbin 6 installed between the first clamping plate 3 and the second clamping plate 5. Furthermore, the first arm 11 and the second arm 12 are relatively fixed. To better achieve the above objectives, it is feasible to consider the connecting portion 13, the first arm 11, and the second arm 12 as an integral structure. Of course, in other feasible embodiments, the first arm 11 and the second arm 12 can be fixedly connected to both ends of the connecting portion 13.

[0045] A displacement mechanism 2 is connected to the first arm 11, and a rotatable first clamping plate 3 is connected to the displacement mechanism 2. The first clamping plate 3 can be connected to the displacement mechanism 2 via a first bearing 4, thereby enabling the first clamping plate 3 to rotate relative to the displacement mechanism 2. The rotation of the first clamping plate 3 is about its own axis. A second clamping plate 5 is rotatably connected to the second arm 12. The second clamping plate 5 can be connected to the second arm 12 via a second bearing 8, thereby enabling the second clamping plate 5 to rotate relative to the second arm 12. The rotation of the second clamping plate 5 is about its own axis. A cylindrical tube 6 is installed between the first clamping plate 3 and the second clamping plate 5. One end of the cylindrical tube 6 can abut or engage with the first clamping plate 3, etc., and the cylindrical tube 6 only needs to be able to drive the first clamping plate 3 to rotate. Similarly, the other end of the cylindrical tube 6 can abut or engage with the second clamping plate 5, etc., and the cylindrical tube 6 only needs to be able to drive the second clamping plate 5 to rotate. The displacement mechanism 2 can drive the first clamping plate 3 to move along its own axis. The displacement mechanism 2 cannot move in the radial direction, therefore, the first clamping plate 3 cannot move in the radial direction either. During the movement of the first clamping plate 3 along its own axis, the axis of the first clamping plate 3 and the axis of the second clamping plate 5 are on the same straight line. When there is a difference in the length of the bobbin 6, the displacement mechanism 2 can drive the first clamping plate 3 to move along its own axis, thereby adjusting the position of the first clamping plate 3 to compensate for the difference in the length of the bobbin 6. During the above compensation process, since the displacement mechanism 2 drives the first clamping plate 3 to move along its own axis, the axis of the first clamping plate 3 is always on the same straight line as the axis of the second clamping plate 5. The rotation axis of the installed bobbin 6 is also located on this straight line. Therefore, the problem of the first clamping plate 3 and the second clamping plate 5 having different axes is completely avoided, which greatly reduces the vibration of the yarn cake caused by the bobbin 6 winding chemical fiber filaments, ensures the forming quality, and greatly improves the service life of the first clamping plate 3, the bearings between the first clamping plate 3 and the displacement mechanism 2, and other components.

[0046] like Figure 4 , Figure 5 , Figure 10 and Figure 11 As shown, the first clamping plate 3 has a first position and a second position. In the first position, the first clamping plate 3 and the second clamping plate 5 can clamp the tube 6, that is, both ends of the tube 6 are abutted or locked by the first clamping plate 3 and the second clamping plate 5 respectively, so that the tube 6 is held on the first clamping plate 3 and the second clamping plate 5, and the tube 6 can drive the first clamping plate 3 and the second clamping plate 5 to rotate. In the second position, the tube 6 can be installed between the first clamping plate 3 and the second clamping plate 5 or removed from the first clamping plate 3 and the second clamping plate 5. The distance between the first clamping plate 3 and the second clamping plate 5 in the first position is smaller than the distance between the first clamping plate 3 and the second clamping plate 5 in the second position. The first position of the first clamping plate 3 changes with the difference in the length of the tube 6. When the length of the tube 6 is shorter, the first position of the first clamping plate 3 is closer to the second clamping plate 5. In the second position, one end of the tube 6 is separated from the first clamping plate 3, therefore, the tube 6 can be installed between the first clamping plate 3 and the second clamping plate 5 or removed from the first clamping plate 3 and the second clamping plate 5.

[0047] Furthermore, the tube clamping mechanism may include a drive mechanism 7. The drive mechanism 7 is used to actuate the displacement mechanism 2 so that at least a portion of the displacement mechanism 2 moves along the axial direction of the first clamping plate 3. For example, the drive mechanism 7 actuates the displacement mechanism 2 so that the first clamping plate 3 moves from a first position to a second position and / or from the second position to the first position.

[0048] In the first implementation, such as Figure 4 and Figure 5 As shown, the first arm 11 has an opening, the axis of which is parallel to or on the same straight line as the axis of the first clamping plate 3. The displacement mechanism 2 may include a mandrel 26 installed in the opening and capable of sliding along the axis of the opening. The mandrel 26 is connected to the first clamping plate 3 via a first bearing 4. By sliding the mandrel 26 in the opening along the axis of the opening, the first clamping plate 3 can move between a first position and a second position. In addition, the first position of the first clamping plate 3 can be adjusted to compensate for the difference in length of the tube 6.

[0049] In this embodiment, such as Figure 1 and Figure 2 As shown, the drive mechanism 7 may include a rotating arm 73 rotatably connected to the bobbin holder 1, and the rotating arm 73 and the bobbin holder 1 may be hinged. The rotation axis of the rotating arm 73 may be arranged in the vertical direction. When the rotating arm 73 rotates away from the bobbin 6, it can drive the mandrel 26 to move away from the bobbin 6, so that the first clamping plate 3 moves from the first position to the second position. When the rotating arm 73 rotates towards the bobbin 6, it can drive the mandrel 26 to move towards the bobbin 6, so that the first clamping plate 3 moves from the second position to the first position.

[0050] As a feasible option, such as Figure 3 As shown, an elastic element 23 may be provided between the first arm 11 and the rotating arm 73. The elastic element 23 causes the rotating arm 73 to tend to rotate towards the bobbin 6. Through the elastic element 23, without any other external force, the rotating arm 73 tends to rotate towards the bobbin 6 under the action of the elastic element 23, thereby allowing the first clamping plate 3 to move from the second position to the first position. Additionally, the rotating arm 73 can also cause the mandrel 26 and the first clamping plate 3 to tend to move along the axis of the first clamping plate 3 towards the bobbin 6, so that the first clamping plate 3 can be held in the first position to maintain clamping the bobbin 6. Through the operator's operation, the rotating arm 73 can overcome the force of the elastic element 23 and rotate away from the bobbin 6, thereby causing the mandrel 26 to move away from the bobbin 6, and thus moving the first clamping plate 3 from the first position to the second position.

[0051] In the above embodiments, such as Figures 4 to 7 As shown, a linkage 74 is connected to the rotating arm 73, which can drive the spindle 26 to slide along the axial direction of the opening. For example, as Figure 8 As shown, the linkage 74 is sleeved on the spindle 26 and abuts against the stepped portion of the side wall of the spindle 26, so as to drive the spindle 26 to move in at least one direction along the axis of the first clamping plate 3. The linkage 74 can be located between the rotating arm 73 and the bearing connected to the first clamping plate 3. Therefore, the linkage 74 can abut against the bearing, allowing the bearing and the first clamping plate 3 to move along the axis of the first clamping plate 3 towards the tube 6, thereby driving the spindle 26 to move along the axis of the first clamping plate 3 towards the tube 6 through the bearing.

[0052] like Figure 6 and Figure 7As shown, the linkage 74 and the rotating arm 73 can generate displacement in the radial direction of the rotation of the rotating arm 73, or the linkage 74 and the spindle 26 can generate displacement in the radial direction of the rotation of the rotating arm 73, thereby ensuring that the rotating arm 73 can rotate at a certain angle. In a specific embodiment, the shape of the hole 742 of the linkage 74 matches the stepped portion of the spindle 26, thereby abutting against the spindle 26 to drive the spindle 26 to move in at least one direction along the axis of the first clamp 3. One side of the linkage 74 is abutted by the stepped portion, and the other side of the linkage 74 is abutted by the first bearing 4. Therefore, the linkage 74 is limited by the stepped portion and the first bearing 4. The rotating arm 73 abuts against the side of the linkage 74 facing the bobbin 6. When the rotating arm 73 rotates towards the bobbin 6, it drives the linkage 74 to move towards the bobbin 6 along the axis of the first clamping plate 3. The linkage 74 pushes the first bearing 4, which in turn drives the spindle 26 and the first clamping plate 3 to move towards the bobbin 6 along the axis of the first clamping plate 3. The linkage 74 is also provided with at least one through hole 741 extending radially along the rotation direction of the rotating arm 73. A connector 75 connected to the rotating arm 73 passes through the through hole 741. When the rotating arm 73 rotates away from the bobbin 6, it drives the linkage 74 to move away from the bobbin 6 along the axis of the first clamping plate 3 via the connector 75. The linkage 74 drives the spindle 26 to move away from the bobbin 6 along the axis of the first clamping plate 3 via the stepped portion. The spindle 26 then drives the first clamping plate 3 to move away from the bobbin 6 along the axis of the first clamping plate 3 via the first bearing 4. During the above process, the connector 75 in the through hole 741 generates a certain displacement relative to the linkage 74 in the radial direction of the rotation of the rotating arm 73.

[0053] In the second implementation, such as Figures 9 to 11 , Figure 13 As shown, the displacement mechanism 2 may include a base mechanism 21, a moving member 22, and an elastic member 23. The base mechanism 21 is connected to the first arm 11. The moving member 22 is connected to the first clamping plate 3 via a first bearing 4. The moving member 22 is movable relative to the base mechanism 21 along the axial direction of the first clamping plate 3, thereby causing the first clamping plate 3 to move along its own axial direction, thus allowing the first clamping plate 3 to have a first position and a second position. An elastic member 23 is provided between the base mechanism 21 and the moving member 22. When the drive mechanism 7 does not act on the first clamping plate 3, the elastic member 23 allows the moving member 22 to keep the first clamping plate 3 in the first position. In addition, the elastic member 23 allows the moving member 22 to move the first clamping plate 3 from the second position to the first position.

[0054] like Figures 10 to 11 , Figure 13As shown, an inflatable space 24 can be formed between the base mechanism 21 and the moving member 22. When the moving member 22 moves relative to the base mechanism 21 along the axial direction of the first clamping plate 3, the volume of the inflatable space 24 changes. Therefore, the volume of the inflatable space 24 can be actively controlled, thereby controlling the movement of the moving member 22 relative to the base mechanism 21 along the axial direction of the first clamping plate 3. Therefore, as... Figure 13 As shown, the displacement mechanism 2 may include a gas port 25 communicating with the inflation space 24. For example... Figure 12 As shown, the drive mechanism 7 includes a gas supply line 72 with a switch unit 71, which is connected to a gas port 25. The gas supply line 72 is used to connect to a gas source, which can provide gas at a certain pressure. When gas is filled into the inflation space 24, the inflation space 24 increases, and the moving member 22 moves relative to the base mechanism 21 along the axial direction of the first clamping plate 3 against the force of the elastic member 23, so that the first clamping plate 3 moves from the first position to the second position. In this embodiment, the operator can control the switch unit 71 to open, so that the gas input through the gas supply line 72 moves the first clamping plate 3 from the first position to the second position and holds it in the second position. At this time, the operator's hands are free, and the tube 6 between the first clamping plate 3 and the second clamping plate 5 can be easily replaced. After replacement, the second clamping plate 5 abuts or locks the other end of the tube 6. The operator can control the switch unit 71 to close, and the elastic element 23 causes the moving element 22 to move the first clamping plate 3 from the second position to the first position. This reduces the gas loss in the inflation space 24, and the first clamping plate 3 abuts against or engages with one end of the tube 6. Alternatively, in other feasible embodiments, the operator can manually move the first clamping plate 3 or the moving element 22, causing the moving element 22 to overcome the force of the elastic element 23 and move relative to the base mechanism 21 along the axial direction of the first clamping plate 3, moving the first clamping plate 3 from the first position to the second position.

[0055] In the above embodiments, as feasible, such as Figures 10 to 11 , Figure 13 As shown, the base mechanism 21 may include a rod 211 extending along the axis of the first clamping plate 3. A movable member 22 is slidably sleeved on the rod 211, allowing the movable member 22 to move relative to the base mechanism 21 along the axial direction of the first clamping plate 3. One end of an elastic member 23 abuts against or connects to the base mechanism 21, and the other end of the elastic member 23 abuts against or connects to the movable member 22. The elastic member 23 may be a component such as a spring. The elastic member 23 causes the movable member 22 to tend to move towards the cylinder 6. When gas is filled into the inflation space 24, the gas causes the movable member 22 to overcome the force of the elastic member 23 and tend to move away from the cylinder 6.

[0056] Specifically, such as Figures 10 to 11 , Figure 13As shown, the base mechanism 21 includes a base base 212 and a base cover 213. The base base 212 and the base cover 213 can be connected together by a fastener. A rod 211 is fixedly connected to the middle of the base base 212. The base cover 213 has a base cover body 2131 extending along the axial direction of the first clamp 3 and an inner edge 2132 extending radially inward at the end of the base cover body 2131 near the first clamp 3. The moving member 22 has a moving member body 221 extending along the axial direction of the first clamp 3 and an outer edge 222 extending radially outward at the end of the moving member body 221 away from the first clamp 3. The outer edge 222 abuts and seals against the inner wall of the base cover body 2131. The inner edge 2132 abuts and seals against the outer wall of the moving member body 221. The movable component body 221 has a groove 2211 at one end near the base base 212, and the other end of the elastic component 23 can be located in the groove 2211, thereby abutting or connecting with the movable component 22. The movable component body 221 is sleeved on the outside of the rod 211, and the base cover 213 is sleeved on the outside of the movable component 22. The outer side wall and outer edge 222 of the movable component body 221, and the inner side wall and inner edge 2132 of the base cover body 2131 form an inflation space 24. The gas port 25 can be located on the base cover 213 and communicates with the inflation space 24 through a channel on the base cover 213. The switch unit 71 can be installed on the first arm 11 for operation by an operator.
