Description

Technical Field

[0001] This application relates to the technical field of FDY spinning, and in particular to an FDY spinning stretching device. Background Technology

[0002] FDY (FULLY DRAWN YARN) refers to yarn produced by introducing stretching during the spinning process to obtain a certain degree of orientation and crystallinity. FDY fabrics have a smooth and soft hand feel and are often used to weave imitation silk fabrics, finding wide applications in clothing and home textiles.

[0003] Currently, a stretching device is required in the FDY spinning process. The stretching device includes a frame and stretching rollers. The stretching rollers are rotatably connected to the frame. There are at least two rows of stretching rollers from top to bottom. Each row of stretching rollers is distributed in the horizontal direction, and the stretching rollers between adjacent rows are staggered in the vertical direction.

[0004] The stretching force of the stretching device needs to be determined by the material and thickness of the spinning yarn. The stretching roller of the stretching device cannot change position, so its stretching force is limited and cannot be flexibly adjusted. It can only be used for stretching a certain specification of spinning material. Summary of the Invention

[0005] The purpose of this application is to provide an FDY spinning stretching device that can adjust the position of the stretching roller to adjust the stretching force of the stretching device, thereby making it suitable for stretching various specifications of spinning materials.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An FDY spinning and stretching apparatus, comprising:

[0008] A frame, wherein at least one sliding opening is provided on the frame;

[0009] At least one fixed stretching roller is provided, and the fixed stretching roller is rotatably connected to the frame.

[0010] Adjustable stretching rollers are set one-to-one with the sliding ports, and one end of the adjustable stretching roller is slidably connected in the sliding port;

[0011] The first drive mechanism drives the fixed stretching roller to rotate via a transmission assembly;

[0012] The second drive mechanism drives the adjustment roller to rotate via a transmission component;

[0013] An adjustment mechanism, corresponding one-to-one with the adjustment stretching roller, is used to adjust the position of the corresponding adjustment stretching roller in the horizontal direction;

[0014] A tensioning mechanism is used to tension the transmission component of the second drive mechanism so that the transmission component of the second drive mechanism is always in a tensioned state when the position of the adjusting tension roller in the horizontal direction is adjusted.

[0015] Preferably, the adjusting mechanism includes a sliding block, an ejector piston, a linkage rod, a rotating rod, and an eccentric wheel. The sliding block slides in the sliding port, the adjusting tension roller is rotatably connected to the sliding block, the frame is provided with an adjusting port, the rotating rod is rotatably connected to the frame, and one end of the rotating rod is located in the adjusting port. The eccentric wheel is connected to the end of the rotating rod located in the adjusting port. A piston displacement port communicates between the adjusting port and the sliding port. The ejector piston slides in the piston displacement port. A push rod is fixedly connected to the side of the sliding block facing the piston displacement port. The push rod contacts the ejector piston. One end of the linkage rod is movably connected to the side of the ejector piston away from the push rod, and the other end is movably connected to the eccentric position of the eccentric wheel.

[0016] Preferably, a reset elastic element is provided on the side of the sliding block away from the top rod, and the reset elastic element is located between the inner wall of the sliding block and the sliding port.

[0017] Preferably, each of the rotating rods is wrapped with a rotation drive rope, and an outer sleeve is rotatably connected to the frame. The number of outer sleeves is the same as the number of rotation drive ropes, and the outer sleeves correspond one-to-one with the rotation drive ropes. The end of the rotation drive rope away from the rotating rod is wrapped around the outer sleeve. Each outer sleeve is connected with an outer ring, and each outer ring is threaded with a locking bolt for abutting against the frame.

[0018] Preferably, the frame is provided with a synchronous transmission mechanism, which can control the rotation of each of the outer sleeves respectively. The synchronous transmission mechanism includes an inner mandrel, a drive motor and a clamping bolt. The number of inner mandrels is the same as the number of outer sleeves, and the inner mandrels correspond one-to-one with the outer sleeves. The inner mandrels are inserted into the outer sleeves. Each outer sleeve has a clamping bolt threaded on its outer side wall. The clamping bolt is used to clamp the inner mandrel. The drive motor is used to drive each inner mandrel to rotate synchronously.

[0019] Preferably, the number of drive motors is one.

[0020] Preferably, the tensioning mechanism is disposed between two adjacent adjusting tension rollers. The tensioning mechanism includes a lifting rod, a lifting elastic element, and a synchronous wheel. One end of the lifting rod is located inside the adjusting port, and the other end extends out of the side wall of the frame and is connected to a baffle. The lifting elastic element is sleeved on the lifting rod and is located between the baffle and the outer side wall of the frame. The synchronous wheel is rotatably connected to the end of the lifting rod located inside the adjusting port. The transmission assembly between two adjacent adjusting tension rollers passes through the synchronous wheel.

[0021] Preferably, the frame is provided with a guide wheel system, which is used to guide the direction of the rotating drive rope and change the direction of the rotating drive rope.

[0022] Compared with existing technologies, the above technical solution has the following advantages:

[0023] 1. The adjustment mechanism can adjust the horizontal position of the tensioning roller to adjust the stretching force of the tensioning device, thus making it suitable for stretching various specifications of spinning materials; the tensioning mechanism can keep the transmission components of the second drive mechanism tensioned during the adjustment process, ensuring smooth transmission effect.

[0024] 2. The rotating rod drives the eccentric wheel to rotate. During the rotation of the eccentric wheel, the linkage rod reciprocates in the horizontal direction. The linkage rod drives the ejector piston to reciprocate in the horizontal direction. The reciprocating motion of the ejector piston and the elastic force of the reset elastic element cooperate with each other to achieve the adjustment of the horizontal position of the sliding block.

[0025] 3. When it is necessary to drive the outer sleeve to rotate, the operator tightens the corresponding locking bolts to ensure synchronous movement between the inner spindle and the outer sleeve. Then, the drive motor is started. The drive motor drives each inner spindle to rotate simultaneously through the transmission assembly. The inner spindles that are locked by the locking bolts drive the outer sleeve to rotate, while the inner spindles that are not locked by the locking bolts idle inside the outer sleeve. During the rotation of the outer sleeve, the inner spindles wind up the rotating drive rope, thereby adjusting the horizontal position of the adjusting tension roller.

[0026] 4. The synchronous transmission mechanism can control the rotation of each outer sleeve with a single drive motor, which reduces the production cost of the entire device. At the same time, when the synchronous transmission mechanism fails to work, only one drive motor needs to be checked, which greatly reduces the difficulty of maintenance.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 In this embodiment, an FDY spinning stretching device is disclosed, including a frame 1, a fixed stretching roller 2, an adjustable stretching roller 3, a first drive mechanism, a second drive mechanism, an adjustment mechanism, and a tensioning mechanism.

[0034] Reference Figure 1 and Figure 2In this embodiment, the frame 1 includes a base 101 and a support frame 102. The base 101 is installed on the ground, and the support frame 102 is fixedly connected to the base 101. At least one fixed stretching roller 2 is provided, and the number of fixed stretching rollers 2 is set according to actual needs. In this embodiment, the number of fixed stretching rollers 2 is not less than two. Each fixed stretching roller 2 is perpendicular to the support frame 102. The fixed stretching rollers 2 are rotatably connected to the support frame 102 through bearings. The multiple fixed stretching rollers 2 are located at the same height and are evenly distributed along the horizontal direction.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the first driving mechanism drives multiple fixed stretching rollers 2 to rotate via the transmission assembly 9. Specifically, the first driving mechanism includes a first motor 401, and a first mounting frame 402 is fixedly connected to the side wall of the support frame 102. The first motor 401 is mounted on the first mounting frame 402. The transmission assembly 9 can be either belt drive or chain drive. The first motor 401 drives multiple fixed stretching rollers 2 to rotate simultaneously via the transmission assembly 9.

[0036] Reference Figure 1 and Figure 2 In this embodiment, at least one sliding opening 103 is provided on the support frame 102. The number of sliding openings 103 is set according to actual needs. In this embodiment, the number of sliding openings 103 is not less than two, and multiple sliding openings 103 are located at the same height and are evenly distributed along the horizontal direction. The sliding openings 103 can be located above or below the fixed stretching roller 2. This embodiment uses the sliding openings 103 located above the fixed stretching roller 2 as an example. In the vertical direction, the projection of each sliding opening 103 is between two adjacent fixed stretching rollers 2.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the adjusting tension roller 3 and the fixed tension roller 2 are located on the same side of the support frame 102. The number of adjusting tension rollers 3 is the same as the number of sliding ports 103, and the adjusting tension rollers 3 and the sliding ports 103 are arranged in a one-to-one correspondence. One end of the adjusting tension roller 3 is slidably connected in the sliding port 103.

[0038] Reference Figure 1 and Figure 2 In this embodiment, the number of adjusting mechanisms is the same as the number of adjusting tension rollers 3, and each adjusting mechanism corresponds to one adjusting tension roller 3. The adjusting mechanism is used to adjust the position of the corresponding adjusting tension roller 3 in the horizontal direction. The adjusting mechanism includes a sliding block 601, an ejector piston 602, a linkage rod 603, a rotating rod 604, and an eccentric wheel 605.

[0039] Reference Figure 1 and Figure 2 Each sliding block 601 is slidably connected in each sliding port 103. The top surface of the sliding block 601 is attached to the inner top wall of the sliding port 103, and the bottom surface of the sliding block 601 is attached to the inner bottom wall of the sliding port 103. The horizontal length of the sliding port 103 is greater than the horizontal length of the sliding block 601, so that the sliding block 601 can slide horizontally in the sliding port 103.

[0040] Reference Figure 1 and Figure 2 Guide bars are bolted to the two inner sidewalls of the sliding port 103 in the horizontal direction. The guide bars extend along the sliding direction of the sliding block 601. Guide grooves that cooperate with the guide bars are provided on the upper and lower surfaces of the sliding block 601. Through the cooperation of the guide bars and guide grooves, the sliding block 601 is prevented from falling out of the sliding port 103 during the horizontal movement, thereby improving the connection stability of the sliding block 601 in the sliding port 103.

[0041] Reference Figure 1 and Figure 2 One end of the adjusting stretching roller 3 is rotatably connected to the sliding block 601 via a bearing. By sliding the sliding block 601 within the sliding port 103, the position of the adjusting stretching roller 3 can be adjusted to regulate the stretching force of the stretching device, thus making it suitable for stretching various specifications of spinning materials.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the frame 1 is provided with adjustment ports 104, the number of which is the same as the number of sliding ports 103, and the adjustment ports 104 and sliding ports 103 correspond one-to-one. The top wall of the support frame 102 is provided with rotating holes, the number of which is the same as the number of adjustment ports 104, and the adjustment ports 104 and rotating holes correspond one-to-one. The rotating holes communicate with the adjustment ports 104. Part of the rotating rod 604 is located in the rotating hole, and a bearing is fixed to the rod of the rotating rod 604. The bearing is fixed in the rotating hole, and the rotating rod 604 is rotatably connected to the support frame 102 through the bearing.

[0043] Reference Figure 1 and Figure 2 One end of the rotating rod 604 is located inside the adjustment port 104, and the other end is positioned above the top wall of the support frame 102. The eccentric wheel 605 is an approximately elliptical cam. One end of the eccentric wheel 605 along its major axis is fixedly connected to the end of the rotating rod 604 located inside the adjustment port 104, and the other end of the eccentric wheel 605 along its major axis is fixedly connected to a cam shaft 6051. During the rotation of the rotating rod 604, the position of the cam shaft 6051 is the eccentric position of the eccentric wheel 605.

[0044] Reference Figure 1and Figure 2 A piston displacement port 105 connects the adjusting port 104 and the sliding port 103, and the ejector piston 602 slides in the piston displacement port 105. A push rod 6011 is fixedly connected to the side of the sliding block 601 facing the piston displacement port 105. The push rod 6011 extends into the piston displacement port 105 and contacts the ejector piston 602. The side of the ejector piston 602 away from the push rod 6011 has a receiving cavity, and a central shaft is provided in the receiving cavity, passing through the center of the receiving cavity. One end of the linkage rod 603 is located in the receiving cavity and has a hinge hole. The central shaft passes through the hinge hole, and there is a rotatable engagement between the central shaft and the hinge hole. The linkage rod 603 achieves a movable connection with the ejector piston 602 through the engagement between the hinge hole and the central shaft.

[0045] Reference Figure 1 and Figure 2 The end of the linkage rod 603 away from the ejector piston 602 has a movable hole, through which the cam shaft 6051 passes, and the cam shaft 6051 is rotatably engaged with the movable hole. The linkage rod 603 achieves a movable connection with the eccentric wheel 605 through the engagement between the movable hole and the cam shaft 6051.

[0046] Reference Figure 1 and Figure 2 The sliding block 601 is provided with a reset elastic element 606 on the side away from the top rod 6011. The reset elastic element 606 is a compression spring and is located between the sliding block 601 and the inner wall of the sliding port 103.

[0047] When the horizontal position of the adjusting tension roller 3 needs to be adjusted, the drive rod 604 rotates, which in turn drives the eccentric wheel 605 to rotate. During rotation, the eccentric wheel 605 drives the linkage rod 603 to reciprocate horizontally, which in turn drives the ejector piston 602 to reciprocate horizontally. When the ejector piston 602 moves towards the sliding port 103, it is driven by the push rod 6011, causing the sliding block 601 to move the adjusting tension roller 3 away from the adjusting port 104. At this time, the reset elastic element 606 is compressed. When the ejector piston 602 moves away from the sliding port 103, the released elasticity of the reset elastic element 606 causes the sliding block 601 to move the adjusting tension roller 3 towards the adjusting port 104. Through the reciprocating motion of the ejector piston 602 and the elastic force of the reset elastic element 606, the horizontal position of the sliding block 601 is adjusted.

[0048] Reference Figures 1-3In this embodiment, a rotation drive rope 607 is wrapped around each rotating rod 604. An outer sleeve 608 is provided on the support frame 102, and the number of outer sleeves 608 is the same as the number of rotation drive ropes 607. Each outer sleeve 608 corresponds one-to-one with a rotation drive rope 607, and the outer sleeve 608 is rotatably connected to the support frame 102 via bearings. The end of the rotation drive rope 607 away from the rotating rod 604 is wrapped around the outer sleeve 608. Each outer sleeve 608 is connected to an outer ring 609, and each outer ring 609 is threaded with a locking bolt 610 for pressing against the outer wall of the support frame 102.

[0049] Reference Figures 1-3 A guide wheel system is provided on the top wall of the support frame 102. The guide wheel system is used to guide the direction of the rotation drive rope 607 and change the direction of the rotation drive rope 607. The guide wheel system includes a horizontal guide wheel 611 and a direction-changing guide wheel group 612.

[0050] Reference Figure 1 and Figure 2 Horizontal guide wheels 611 are mounted on the top wall of the support frame 102. The number of horizontal guide wheels 611 is the same as the number of rotating drive ropes 607, and there is a one-to-one correspondence between the horizontal guide wheels 611 and the rotating drive ropes 607. Each horizontal guide wheel 611 can guide the direction of each rotating drive rope 607 in an alternating manner, thereby preventing multiple rotating drive ropes 607 from moving on the same path.

[0051] Reference Figure 3 The reversing guide wheel assembly 612 includes a bracket 6121 and a reversing guide wheel 6122. The bracket 6121 is fixedly connected to the corner of the support frame 102, and the reversing guide wheel 6122 is rotatably connected to the bracket 6121. The number of reversing guide wheels 6122 is the same as the number of rotating drive ropes 607, and the reversing guide wheels 6122 and the rotating drive ropes 607 correspond one-to-one.

[0052] The guide pulley 6122 can change the direction of movement of the rotating drive rope 607, so that the rotating drive rope 607 can move towards the outer sleeve 608. In addition, the guide pulley 6122 corresponds one-to-one with the rotating drive rope 607. When one rotating drive rope 607 moves while the others do not move, the rotation of the guide pulley 6122 can avoid wear on the other stationary rotating drive ropes 607, thereby improving the service life of the rotating drive ropes 607.

[0053] When the horizontal position of the adjusting tension roller 3 needs to be adjusted, the operator loosens the corresponding locking bolt 610 and drives the corresponding outer sleeve 608 to rotate. The outer sleeve 608 winds up the corresponding rotating drive rope 607. During the winding of the rotating drive rope 607, the rotating drive rope 607 drives the corresponding rotating rod 604 to rotate, thereby causing the corresponding ejector piston 602 to reciprocate in the horizontal direction. After the position of the adjusting tension roller 3 is adjusted, the operator tightens the corresponding locking bolt 610 until it is pressed against the outer wall of the support frame 102, thereby fixing the position of the adjusting tension roller 3.

[0054] Reference Figure 1 and Figure 2 In this embodiment, a synchronous transmission mechanism is provided on the side wall of the support frame 102, which can control the rotation of each outer sleeve 608 respectively. The synchronous transmission mechanism includes an inner spindle 613, a drive motor 614, and a clamping bolt 615.

[0055] Reference Figures 1-3 The number of inner mandrels 613 is the same as the number of outer sleeves 608. A second mounting bracket 616 is fixedly connected to the side wall of the support frame 102. Multiple inner mandrels 613 are arranged side by side on the second mounting bracket 616, and the inner mandrels 613 are rotatably connected to the second mounting bracket 616. A third mounting bracket 617 is fixedly connected to the side wall of the support frame 102. A drive motor 614 is mounted on the third mounting bracket 617. There is one drive motor 614. The drive motor 614 drives multiple inner mandrels 613 to rotate simultaneously through a transmission assembly 9. The transmission assembly 9 can be either belt drive or chain drive. Each inner mandrel 613 corresponds to one outer sleeve 608. The outer diameter of the inner mandrel 613 is smaller than the inner diameter of the outer sleeve 608. The inner mandrel 613 is inserted into the outer sleeve 608. A clamping bolt 615 is threadedly connected to the outer side wall of each outer sleeve 608. The clamping bolt 615 is used to clamp the inner mandrel 613.

[0056] When the outer sleeve 608 needs to be rotated, the operator tightens the corresponding locking bolts 615 to ensure synchronous movement between the inner spindle 613 and the outer sleeve 608. Simultaneously, the operator loosens the corresponding locking bolts 610. Then, the drive motor 614 is started. The drive motor 614, through the transmission assembly 9, simultaneously drives each inner spindle 613 to rotate. The inner spindles 613 that are locked by the locking bolts 615 drive the outer sleeve 608 to rotate, while the inner spindles 613 that are not locked by the locking bolts 615 idle within the outer sleeve 608. During the rotation of the outer sleeve 608, the inner spindles 613 wind up the rotating drive rope 607, thereby adjusting the horizontal position of the adjusting tension roller 3.

[0057] The synchronous transmission mechanism can control the rotation of each outer sleeve 608 separately through a single drive motor 614, which reduces the production cost of the entire device. At the same time, when the synchronous transmission mechanism fails to work, only one drive motor 614 needs to be checked, which greatly reduces the difficulty of maintenance.

[0058] Reference Figure 2 The second drive mechanism drives the adjusting tension rollers 3 to rotate via the transmission assembly 9. Specifically, the second drive mechanism includes a second motor 501, and a fourth mounting bracket 502 is fixedly connected to the side wall of the support frame 102. The second motor 501 is mounted on the fourth mounting bracket 502. The transmission assembly 9 can be either a belt drive or a chain drive. The second motor 501 drives multiple adjusting tension rollers 3 to rotate simultaneously via the transmission assembly 9.

[0059] Reference Figure 1 and Figure 2 In this embodiment, a tensioning mechanism is used to tension the transmission component 9 of the second drive mechanism so that the transmission component 9 of the second drive mechanism is always in a tensioned state when adjusting the position of the adjusting tension roller 3 in the horizontal direction, thereby ensuring the transmission effect. The tensioning mechanism is disposed between two adjacent adjusting tension rollers 3 and between the adjusting tension roller 3 and the second motor 501 near the second motor 501. The tensioning mechanism includes a lifting rod 701, a lifting elastic element 702, and a synchronous pulley 703.

[0060] Reference Figure 1 and Figure 2 The support frame 102 has lifting holes on its top wall. The number of lifting holes matches the number of adjustment ports 104. Each adjustment port 104 corresponds to one lifting hole, and the lifting holes communicate with each other. The lifting rod 701 passes through the lifting holes and can move freely up and down within them. One end of the lifting rod 701 is located inside the adjustment port 104, and the other end extends out of the top wall of the support frame 102 and is connected to a baffle 7011. A lifting elastic element 702 is sleeved on the lifting rod 701 and is located between the baffle 7011 and the outer wall of the frame 1. The lifting elastic element 702 is a compression spring. A synchronous pulley 703 is rotatably connected to the end of the lifting rod 701 located inside the adjustment port 104. The transmission assembly 9 between two adjacent adjusting tension rollers 3 and the transmission assembly 9 between the adjusting tension roller 3 near the second motor 501 and the second motor 501 respectively pass through their corresponding synchronous pulleys 703.

[0061] When adjusting the position of the tension roller 3, when two adjacent tension rollers 3 are close to each other, the transmission component 9 between the two adjacent tension rollers 3 is in a relaxed state. At this time, the elastic force of the lifting elastic element 702 causes the synchronous wheel 703 to move upward to re-tension the transmission component 9. When two adjacent tension rollers 3 are far apart from each other, the transmission component 9 between the two adjacent tension rollers 3 is in a state of over-tension. At this time, the tension of the transmission component 9 causes the synchronous wheel 703 to move downward. When it descends to a certain extent, the downward pressure on the synchronous wheel 703 is balanced with the elastic force of the lifting elastic element 702, so that the transmission component 9 returns to a better tension state.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention.
