Description

Technical Field

[0001] This application relates to the field of chemical fiber processing equipment technology, specifically to a multi-stage drawing tester for composite filament FDY. Background Technology

[0002] The multi-stage drawing tester for composite filament FDY is a test equipment specifically designed for the production of high-fiber island composite filaments. This equipment produces high-quality composite filaments by passing raw material chips through a series of processes, including drying, melting, extrusion, spinning, cooling, drawing, and setting. Traditional FDY drawing equipment is mostly an industrial-grade single-roller or double-roller structure.

[0003] An existing patent (publication number: CN217499517U) discloses a multi-stage drawing test machine device for high-fiber-density island-type composite filament FDY, including a high-speed winding device; a drying host feed port installed on the top end face of the machine body is connected to the A screw for feeding, and a B screw is connected to the feed port of the storage tank for feeding. The A and B screws are connected to the composite spinning box through a metering pump transmission system. The composite spinning box is connected to a biphenyl heating system for heating through a pipeline. The spinnerets ejected from the spinneret port at the bottom of the composite spinning box are collected along the channel to the pre-network, and the pre-network extends the extension end of the spinnerets into the traction device. This utility model improves the uniformity and rate of oiling of the yarn, thereby improving product quality; it utilizes a metering pump transmission system to increase the installation speed on the construction site; it uses two sets of biphenyl heating systems to achieve temperature control of the individual box; and the design of the dual-channel side blowing system improves the flexibility of the equipment's operation.

[0004] However, in the existing composite filament FDY drawing test equipment, it was found that the number of drawing stages of the drawing test machine is small, and the distance between the active roller and the driven roller in the drawing roller group cannot be adjusted, which makes the drawing force uncontrollable. This results in poor adaptability of the equipment and makes it difficult to meet the experimental requirements of filaments with different fineness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a multi-stage drafting tester for composite filament FDY, which has advantages such as easy adjustment of the distance between the driving roller and the driven roller. It solves the problems of limited drafting stages, inability to adjust the distance between the driving roller and the driven roller, resulting in uncontrollable drafting force, poor adaptability, and difficulty in adapting to the experimental requirements of filaments with different fineness.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-stage drawing tester for composite filament FDY, comprising mounting plates and frames arranged at equal intervals, a motor fixedly mounted on the bottom surface of each mounting plate, a drive roller fixedly connected to the output shaft of each motor, a sprocket one fixedly connected to the outer surface of each drive roller, a chain drivingly connected to the outer surface of each sprocket one, a sprocket two and a sprocket three drivingly connected to each chain, a driven roller fixedly connected to the inner wall of each sprocket two, a sliding block one rotatably connected to the outer surface of each driven roller, a threaded rod threadedly connected to the inner wall of each sliding block one, a sliding block two rotatably connected to the inner wall of each sprocket three, and a spring fixedly connected to the left side of each sliding block two.

[0007] Through the above scheme, in order to facilitate the adjustment of the roller spacing, a motor is set to provide power to the drive roller. Through the connection between sprocket one, chain, sprocket two, and sprocket three, the driven roller can rotate with the drive roller. When it is necessary to adjust the roller spacing, the corresponding threaded rod is rotated so that sliding block one can rise and fall on the surface of the threaded rod. Since the position of sprocket one does not change and the length of the chain remains unchanged, a spring is set on the left side of sliding block two. When sliding block one and the driven roller rise and fall under the action of the threaded rod, the spring can tighten sliding block two, so that sprocket three is always connected to the chain, and thus sprocket two can also be connected to the chain at all times. This achieves the effect of facilitating the adjustment of the spacing between the drive roller and the driven roller, and improves the stretching control capability of the device. The drive roller is equipped with an annular heating chamber. Each drive roller is divided into three independent temperature control zones. A PID temperature control module is used to improve the uniformity of the roller surface temperature.

[0008] Furthermore, each of the mounting plates has a sliding groove 1 and a sliding groove 2 on its front side. The outer surface of each sliding block 1 is slidably connected to the inner wall of the corresponding sliding groove 1. The top and bottom ends of each threaded rod are rotatably connected to the inner top and inner bottom walls of the corresponding sliding groove 1.

[0009] The above scheme involves opening sliding groove one and sliding groove two on the front of the corresponding mounting plate to achieve positioning of sliding groove one and sliding groove two. Sliding block one is connected to the corresponding sliding groove one as a sliding connection to achieve the limiting effect of sliding block one. The top and bottom ends of the threaded rod are connected to the inner top wall and inner bottom wall of the corresponding sliding groove one as a rotating connection to achieve the limiting of the threaded rod. Thus, when the threaded rod rotates, sliding block one can rise and fall.

[0010] Furthermore, the outer surface of each of the two sliding blocks is slidably connected to the inner wall of the corresponding two sliding grooves, and the other end of each spring is fixedly connected to the inner wall of the corresponding two sliding grooves.

[0011] By using the above scheme, the outer surface of the sliding block 2 is connected to the inner wall of the corresponding sliding groove 2 to form a sliding connection, thereby achieving the limiting effect of the sliding block 2. The other end of the spring is connected to the inner wall of the corresponding sliding groove 2 to fix the other end of the spring, so that the spring can always pull the sliding block 2 taut, ensuring that sprocket 1, chain, sprocket 2 and sprocket 3 can always be connected.

[0012] Furthermore, two guide rods are fixedly installed on the inner wall of each of the two sliding grooves, and the outer surface of each guide rod is slidably connected to the inner wall of the corresponding two sliding block.

[0013] The above scheme allows the guide rods to be installed on the inner wall of the sliding groove 2, achieving the positioning and installation effect of the guide rods. Furthermore, the surface of each guide rod can be connected to the corresponding sliding block 2, setting a sliding connection between them to achieve secondary positioning of the sliding block 2.

[0014] Furthermore, each mounting plate has dovetail blocks arranged at equal intervals fixedly connected to its front side, and dovetail grooves arranged at equal intervals fixedly installed on the inner wall of the frame. Each dovetail block is fixedly installed to its corresponding dovetail groove by bolts. A control system is fixedly installed on the back of the frame, and a limit frame arranged at equal intervals is fixedly connected to the front of the frame.

[0015] The above scheme involves installing the dovetail block on the front of the corresponding mounting plate for a fixed connection, and setting the dovetail groove on the inner wall of the corresponding groove in the frame. During installation, the mounting plate is moved to connect the dovetail block and the dovetail groove, and then fixed with bolts for easy disassembly and reassembly. The control system is set on the back of the frame to achieve the positioning and installation effect of the control system, and the limit frame is set on the front of the frame to achieve the positioning and installation effect of the limit frame.

[0016] Furthermore, each of the limiting frames has a worm gear rotatably connected to its inner wall, and each worm gear has a worm wheel meshing on its outer surface. The back of each worm wheel is rotatably connected to the front of the frame.

[0017] The above scheme involves installing the worm gear on the inner wall of the corresponding limiting frame and setting it as a rotatable connection to achieve the limiting effect on the worm gear. The worm wheel is set on the side of the corresponding worm gear, and the worm gear is connected to the corresponding worm wheel. The rotation of the worm gear enables the worm wheel to rotate. The front of the frame is connected to the rod on the back of the worm wheel and set as a rotatable connection to achieve the limiting effect on the worm wheel.

[0018] Furthermore, a connecting rod is fixedly connected to the outer surface of each worm gear, and a tension sensor is fixedly installed on the front side of each connecting rod.

[0019] With the above scheme, the connecting rod is installed on the outer surface of the worm gear and set as a fixed connection. When the worm gear rotates, the connecting rod can rotate with it, which makes it easy to adjust the angle of the connecting rod. The tension sensor is set on the front of the connecting rod, and the tension sensor can feed back the tension on the guide wire to the control system.

[0020] Furthermore, each of the connecting rods has a guide wheel rotatably connected to its outer surface, and each guide wheel has a polyurethane layer on its outer surface.

[0021] The above scheme involves mounting the guide wheel on the outer surface of the connecting rod and setting it as a rotatable connection to limit the movement of the guide wheel. A polyurethane layer is then applied to the surface of the guide wheel, which improves the wear resistance of the guide wheel and its protection of the fibers.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This composite filament FDY multi-stage drawing tester device, by setting up components such as sliding block 2, spring, and sliding block 1, allows for adjustment of the roller spacing when the corresponding threaded rod is rotated, causing sliding block 1 to rise and fall, thereby causing the driven roller to rise and fall. At this time, under the action of the spring, sliding block 2 and sprocket 3 can move, automatically adapting to the position of sliding block 2, so that sprocket 1, chain, sprocket 2 and sprocket 3 can remain connected, thereby allowing the spacing between the driving roller and the driven roller to be adjusted, improving the drawing control capability of the device. By rotating the worm gear, the worm wheel can be rotated, thereby allowing the connecting rod and guide wheel to adjust their angles, improving the adaptability of the device.

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 this application.

[0033] Please see Figure 2 , Figure 4 and Figure 5 This embodiment of a composite filament FDY multi-stage drawing tester includes mounting plates 1 and frames 16 arranged at equal intervals. A motor 2 is fixedly mounted on the bottom surface of each mounting plate 1. An active roller 3 is fixedly connected to the output shaft of each motor 2.

A sliding block 10 is rotatably connected to the inner wall of each sprocket 11. A spring 12 is fixedly connected to the left side of each sliding block 10.

[0034] Please see Figure 4 and Figure 5 Each mounting plate 1 has a sliding groove 7 and a sliding groove 9 on its front side. The outer surface of each sliding block 15 is slidably connected to the inner wall of the corresponding sliding groove 7. The top and bottom ends of each threaded rod 8 are rotatably connected to the inner top and inner bottom walls of the corresponding sliding groove 7. The sliding grooves 7 and 9 are positioned on the front side of the mounting plate 1 to achieve positioning of the sliding grooves 7 and 9.

[0035] Please see Figure 4 and Figure 5 Each sliding block 10 has its outer surface slidably connected to the inner wall of the corresponding sliding groove 9, and the other end of each spring 12 is fixedly connected to the inner wall of the corresponding sliding groove 9. Connecting the outer surface of the sliding block 10 to the inner wall of the corresponding sliding groove 9 is a sliding connection, which achieves the limiting effect of the sliding block 10. Connecting the other end of the spring 12 to the inner wall of the corresponding sliding groove 9 can fix the other end of the spring 12, so that the spring 12 can always pull the sliding block 10 tight, ensuring that the sprocket 4, chain 5, sprocket 6 and sprocket 11 can always be connected.

[0036] Please see Figure 4 and Figure 5 Two guide rods 13 are fixedly installed on the inner wall of each sliding groove 2 9. The outer surface of each guide rod 13 is slidably connected to the inner wall of the corresponding sliding block 2 10. The guide rods 13 are installed on the inner wall of the sliding groove 2 9 to achieve the positioning and installation effect of the guide rods 13. The surface of each guide rod 13 can be connected to the corresponding sliding block 2 10, and the two are set as a sliding connection to achieve secondary limiting of the sliding block 2 10.

[0037] Please see Figure 3 , Figure 4 and Figure 5 Each mounting plate 1 has dovetail blocks 18 fixedly connected to its front side at equal intervals. The inner wall of the frame 16 has dovetail grooves 17 fixedly installed at equal intervals. Each dovetail block 18 is fixedly installed to the corresponding dovetail groove 17 by bolts. The control system 19 is fixedly installed on the back of the frame 16. The front of the frame 16 has limit frames 20 fixedly connected at equal intervals. The dovetail blocks 18 are installed on the front side of the corresponding mounting plate 1 for fixed connection. The dovetail grooves 17 are set in the inner wall of the corresponding groove of the frame 16. During installation, the mounting plate 1 is moved so that the dovetail blocks 18 are connected to the dovetail grooves 17. Then, they are fixed by bolts for easy disassembly and reassembly. The control system 19 is set on the back of the frame 16 to achieve the positioning and installation effect of the control system 19. The limit frames 20 are set on the front of the frame 16 to achieve the positioning and installation effect of the limit frames 20.

[0038] Please see Figure 2 and Figure 6Each limiting frame 20 has a worm gear 21 rotatably connected to its inner wall, and a worm wheel 22 meshes with the outer surface of each worm gear 21. The back of each worm wheel 22 is rotatably connected to the front of the frame 16. The worm gear 21 is installed on the inner wall of the corresponding limiting frame 20 and configured as a rotatable connection to achieve the limiting effect of the worm gear 21. The worm wheel 22 is set on the side of the corresponding worm gear 21 and the worm gear 21 is connected to the corresponding worm wheel 22. The rotation of the worm gear 21 enables the worm wheel 22 to rotate. The front of the frame 16 is connected to the rod on the back of the worm wheel 22 and configured as a rotatable connection to achieve the limiting effect of the worm wheel 22.

[0039] Please see Figure 2 and Figure 6 Each worm gear 22 has a connecting rod 23 fixedly connected to its outer surface. Each connecting rod 23 has a tension sensor 24 fixedly installed on its front side. The connecting rod 23 is installed on the outer surface of the worm gear 22 and is set as a fixed connection. When the worm gear 22 rotates, the connecting rod 23 can rotate with it, which makes it easy to adjust the angle of the connecting rod 23. The tension sensor 24 is set on the front side of the connecting rod 23. The tension sensor 24 can feed back the tension on the guide wire to the control system 19.

[0040] Please see Figure 1 , Figure 2 and Figure 6 Each connecting rod 23 has a guide wheel 25 rotatably connected to its outer surface. Each guide wheel 25 has a polyurethane layer 26 on its outer surface. The guide wheel 25 is mounted on the outer surface of the connecting rod 23 and is configured as a rotatable connection to limit the position of the guide wheel 25. A polyurethane layer 26 is provided on the surface of the guide wheel 25. The polyurethane layer 26 can improve the wear resistance of the guide wheel 25 and the protection of the fiber.

[0041] In this embodiment, a multi-stage drawing tester for composite filament FDY is provided. By setting components such as sliding block 2 10, spring 12, and sliding block 15, when the roller spacing needs to be adjusted, the corresponding threaded rod 8 is rotated to allow the corresponding sliding block 15 to rise and fall, thereby allowing the driven roller 14 to rise and fall. At this time, under the action of spring 12, sliding block 2 10 and sprocket 3 11 can move and automatically adapt to the position of sliding block 2 10, so that sprocket 1 4, chain 5, sprocket 2 6 and sprocket 3 11 can remain connected, thereby allowing the spacing between the driving roller 3 and the driven roller 14 to be adjusted, improving the drawing control capability of the device. By rotating worm gear 21, worm wheel 22 is rotated, thereby allowing the connecting rod 23 and guide wheel 25 to adjust their angles, improving the adaptability of the device.

[0042] It should be noted that the motor 2, drive roller 3 and driven roller 14 installed on the mounting plate 1 form a group of drafting rollers. This device is equipped with three to five groups of drafting rollers, and each guide roller 25 is set between two adjacent groups of drafting rollers.

[0043] The working principle of the above embodiments is as follows:

[0044] The mounting plate 1 can be fixed to the frame 16 by using the dovetail block 18 and the dovetail groove 17 with bolts. When the roller spacing needs to be adjusted, the corresponding threaded rod 8 is rotated to allow the corresponding sliding block 15 and driven roller 14 to rise and fall. At this time, under the action of the spring 12, the sliding block 20 and the sprocket 31 can move. The sliding groove 17 and the sliding groove 29 limit the sliding block 15 and the sliding block 20, so that the sprocket 31 can automatically adapt to the position of connection with the chain 5, so that the sprocket 14, the chain 5, and the sprocket can be connected. The connection between the second roller 6 and the third sprocket 11 allows the distance between the driving roller 3 and the driven roller 14 to be adjusted, thereby improving the drafting control capability of the device. The uniformly distributed heating chamber inside the driving roller 3 can improve the temperature uniformity of the roller surface. When it is necessary to adjust the angle of the guide roller 25, the worm gear 21 is rotated to make the worm wheel 22 rotate, which in turn drives the connecting rod 23 to rotate. At this time, the angle of the guide roller 25 can be adjusted. The polyurethane layer 26 can improve the wear resistance of the guide roller 25 and the protection of the fiber.
