Description

Technical Field

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

[0002] Spinning is the process of processing polymer materials into continuous fibers using specific equipment. It is one of the core processes in industries such as chemical fibers, textiles, and composite materials. During the spinning process, if the tension is too low, the fiber will not be subjected to enough force during stretching, while if the tension is too high, the fiber may be overstretched. To avoid this, a tension adjustment device is needed.

[0003] Current spinning tension regulating devices have poor anti-static effects during use. When the spinning thread passes through the tension regulating component, static electricity is generated due to the pressure contact between the thread and the tension regulating component. Static electricity can cause the thread to loosen or burst when it extends out of the tension regulating mechanism, and it can also attract dust from the air, affecting the color of the thread. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a spinning tension regulating device that can regulate fiber tension during the spinning process and effectively control the impact of static electricity generated during fiber transport on the fiber.

[0005] This utility model discloses a spinning tension adjusting device, including a base, a bearing at one end of the base, a winding roller rotatably connected inside the bearing, a second motor connected to the back side of the base, one end of the output shaft of the second motor being fixedly connected to the winding roller, a pair of positioning rollers connected from top to bottom on the front side of the base relative to the other end of the bearing, a base plate connected to the middle of the front side of the base, a pair of electric push rods connected above the base plate, a lifting plate connected to the top of the electric push rods, a pair of side plates connected above the lifting plate, a lifting roller connected to the inner side of the side plates, and a first antistatic mechanism provided on the outer side of the lifting rollers.

[0006] The first antistatic mechanism includes a conductive ceramic sleeve, an insulating ceramic sleeve connected to the inner wall of the conductive ceramic sleeve, the inner wall of the insulating ceramic sleeve being fixedly connected to the lifting roller, a down conductor connected to the outer side of the conductive ceramic sleeve, a grounding plate connected to the end of the down conductor, a pair of grounding steel pipes connected to the bottom of the grounding plate, and the down conductor being in contact with the conductive ceramic sleeve and being able to rotate relative to it.

[0007] To further enhance the elimination of static electricity on the fibers, a dust cover is connected to the front side of the base above the lifting roller. A second antistatic mechanism is provided inside the dust cover. The second antistatic mechanism includes an air distribution duct, with eight air nozzles connected to the bottom of the air distribution duct and an air supply duct connected to the top of the air distribution duct. One end of the air supply duct passes through the top of the dust cover and is connected to an ion fan.

[0008] To expand the air delivery range of the ion wind, a first motor is connected to the outside of the dust cover. One end of the output shaft of the first motor passes through the dust cover and is connected to a reciprocating lead screw. One end of the reciprocating lead screw is rotatably connected to a bearing seat, which is fixed to the dust cover. The reciprocating lead screw is rotatably mounted inside the dust cover via the bearing seat and the first motor. A ball bearing nut assembly is connected to the upper part of the reciprocating lead screw. A fixing sleeve is fixedly connected to the outside of the ball bearing nut assembly. The bottom of the fixing sleeve is fixedly connected to the air distribution duct. The air distribution duct is slidably connected to the inner wall of the dust cover. The air delivery duct is a flexible hose.

[0009] The length of the air distribution duct is the same as the length of the lifting roller.

[0010] The eight air nozzles are symmetrically distributed around the fixed sleeve, with even spacing between the air nozzles on the same side.

[0011] The spinning tension regulating device obtained by this invention has the following effects:

[0012] By activating the electric push rod, the height of the lifting roller at the top is raised, lifting the spinning yarn upwards from the middle, changing the tension of the spinning yarn. An insulating ceramic sleeve is placed on the outside of the lifting roller, and a conductive ceramic sleeve is placed on the outside of the insulating ceramic sleeve. A down conductor is set on one side of the conductive ceramic sleeve, and a grounding plate and a grounding steel pipe are set at the end of the down conductor. The conductive ceramic sleeve is in direct contact with the spinning yarn, and its conductivity conducts the static electricity generated on the surface of the yarn due to friction and separation to itself. The static electricity is transferred through the down conductor to the grounding plate and the grounding steel pipe, and finally conducted to the ground, realizing the rapid neutralization and release of static electricity.

[0013] By turning on the ion fan, ion air is easily delivered into the nozzle through the air supply pipe and air distribution pipe, and then sprayed downwards through the nozzle. This helps to neutralize the static electricity on the fiber bundle with ions. At the same time, the first motor is turned on to drive the reciprocating screw to rotate, which in turn drives the ball nut pair and the outer fixed sleeve to move back and forth. This further facilitates the back and forth movement of the nozzle. When the nozzle moves back and forth, the coverage of the ion air is no longer limited to a fixed area, but can act more evenly on the entire length of the fiber bundle, increasing the amount and uniformity of ions contacted by each part of the fiber bundle, and improving the antistatic effect.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example 1:

[0020] like Figures 1-4 As shown, this utility model discloses a spinning tension adjustment device, including a base 4. A bearing 16 is provided at one end of the base 4. A winding roller is rotatably connected inside the bearing 16. A second motor 17 is connected to the back side of the base 4. One end of the output shaft of the second motor 17 is fixedly connected to the winding roller. A pair of positioning rollers 5 are connected from top to bottom on the front side of the base 4 relative to the other end of the bearing 16. A base plate 11 is connected to the middle position of the front side of the base 4. A pair of electric push rods 10 are connected above the base plate 11. A lifting plate 9 is connected to the top of the electric push rods 10. A pair of side plates 7 are connected above the lifting plate 9. A lifting roller 25 is connected to the inner side of the side plate 7. A first antistatic mechanism is provided on the outer side of the lifting roller 25.

[0021] In practical use, the spun yarn passes between the two positioning rollers 5 and is wound onto the winding roller 8. The second motor 17 drives the winding roller 8 to rotate, thereby winding the spun yarn. The raising and lowering of the electric push rod 10 can push the raising and lowering of the lifting roller 25 at its top, changing the height position of the lifting roller 25, thus lifting the spun yarn upwards and ultimately changing the tension of the yarn. During the spinning process, the lifting roller 25 is in contact with the spinning yarn. Static electricity generated during the spinning process can be eliminated by the first antistatic mechanism, thereby avoiding the influence of static electricity on the spinning and improving the spinning quality.

[0022] The first antistatic mechanism includes a conductive ceramic sleeve 6, with an insulating ceramic sleeve 24 connected to the inner wall of the conductive ceramic sleeve 6. The inner wall of the insulating ceramic sleeve 24 is fixedly connected to the lifting roller 25. A lead wire 12 is connected to the outer side of the conductive ceramic sleeve 6, and a grounding plate 13 is connected to the end of the lead wire 12. A pair of grounding steel pipes 14 are connected to the bottom of the grounding plate 13. The lead wire 12 is in contact with the conductive ceramic sleeve 6 and can rotate relative to it. By sequentially covering the outside of the lifting roller 25 with the insulating ceramic sleeve 24 and the conductive ceramic sleeve 6, during the spinning lifting and tensioning process, the spinning yarn comes into contact with the conductive ceramic sleeve 6. The static electricity generated during the spinning conveying and tensioning process will be conducted to the conductive ceramic sleeve 6, and the conductive ceramic sleeve 6 will then transfer the static electricity to the ground through the lead wire 12, the grounding plate 13, and the grounding steel pipes 14, thereby eliminating the static electricity on the spinning yarn. The insulating ceramic sleeve 24 prevents static electricity from entering the lifting roller 25, the electric push rod 10, etc., and affecting the normal operation of the equipment. To reduce friction between the lifting roller 25 and the spinning process, the lifting roller 25 can be rotatable relative to the side plate 7. Therefore, the insulating ceramic sleeve 24 and the conductive ceramic sleeve 6 rotate together with the lifting roller 25, while the lead wire 12 is fixed. Thus, the lead wire 12 is in contact with the outer side of the conductive ceramic sleeve 6, and both can rotate freely. They are not connected in a fixed manner, so that the rotation of the conductive ceramic sleeve 6 will not drive the lead wire 12 to move. However, the lead wire 12 is always in contact with the outer side of the conductive ceramic sleeve 6, which can guide static electricity to the ground.

[0023] In other embodiments, to further enhance the elimination of static electricity on the fibers, a dust cover 2 is connected to the front side of the base 4 above the lifting roller 25. A second antistatic mechanism is provided inside the dust cover 2. The second antistatic mechanism includes a distribution duct 22, with eight air nozzles 23 connected to the bottom of the distribution duct 22 and an air supply duct 1 connected to the top of the distribution duct 22. One end of the air supply duct 1 passes through the top of the dust cover 2 and is connected to an ion fan 15.

[0024] The dust cover 2 is designed to effectively isolate some dust from contacting the spinning process. At the same time, the dust cover 2 can also serve as the mounting carrier for the air distribution duct 22. The ion fan 15 can deliver ion air through the air supply duct 1 and the air distribution duct 22 to the air nozzle 23 and spray it downwards through the air nozzle 23. The ion air then comes into contact with the spinning process and neutralizes the static electricity on the yarn bundle through ions, thereby further enhancing the elimination of static electricity on the yarn bundle.

[0025] To expand the air delivery range of the ion wind, a first motor 3 is connected to the outside of the dust cover 2. One end of the output shaft of the first motor 3 passes through the dust cover 2 and is connected to a reciprocating screw 19. One end of the reciprocating screw 19 is rotatably connected to a bearing seat 18. The bearing seat 18 is fixed on the dust cover 2. The reciprocating screw 19 is rotatably mounted inside the dust cover 2 via the bearing seat 18 and the first motor 3. A ball bearing nut assembly 21 is connected to the upper part of the reciprocating screw 19. A fixing sleeve 20 is fixedly connected to the outside of the ball bearing nut assembly 21. The bottom of the fixing sleeve 20 is fixedly connected to the air distribution duct 22. The air distribution duct 22 is slidably connected to the inner wall of the dust cover 2. The air delivery duct 1 is a flexible hose.

[0026] The dust cover 2 has a first motor 3 mounted at one end and a bearing seat 18 fixed at the other end. A reciprocating screw 19 is positioned between them, located inside the dust cover 2 and above the lifting roller 25. The dust cover screw and the lifting roller 25 are arranged perpendicularly. A ball nut assembly 21 is mounted on the reciprocating screw 19, and the ball nut assembly 21 is connected to the air distribution pipe 22 via a fixed sleeve 20. The air distribution pipe 22 is slidably connected to the inner wall of the dust cover 2. Therefore, when the reciprocating screw 19 rotates, the ball nut assembly 21 cannot rotate; it can only move on the reciprocating screw 19, thereby driving the reciprocating movement of the air distribution pipe 22. The sliding direction between the air distribution pipe 22 and the dust cover 2 is consistent with the axial direction of the reciprocating screw 19. The reciprocating screw 19 and the ball nut assembly 21 are essentially a ball screw nut assembly. The sliding connection between the end of the air distribution duct 22 and the dust cover 2 can be achieved by: setting a slide rail on the inner wall of the dust cover 2 and setting a slider at the end of the air distribution duct 22, with the slide rail and slider engaging in a sliding connection. Since the reciprocating screw 19 drives the air distribution duct 22 to move back and forth, the connection position between the air distribution duct 22 and the air supply duct 1 will shift; therefore, the air supply duct 1 is a flexible hose. Since the air supply duct 1 needs to pass through the dust cover 2, and the distance between the air distribution duct 22 and the dust cover 2 is relatively small, an elongated hole can be provided on the dust cover 2 to allow for displacement of the air supply duct 1, thus avoiding interference between the air supply duct 1 and the dust cover 2.

[0027] The length of the air distribution duct 22 is the same as the length of the lifting roller 25. The eight air nozzles 23 are symmetrically distributed around the fixed sleeve 20, with uniform spacing between nozzles on the same side. This results in a more uniform ion air output distribution, allowing for more even application to the fiber bundle and better removal of static electricity.

[0028] In this embodiment, by turning on the ion fan 15, ion air is easily delivered into the air nozzle 23 through the air supply pipe 1 and the air distribution pipe 22, and then sprayed downwards through the air nozzle 23. This facilitates the neutralization of static electricity on the fiber bundle by using ions. At the same time, the first motor 3 is turned on, which facilitates the rotation of the reciprocating screw 19, thereby driving the ball nut assembly 21 and the outer fixing sleeve 20 to move back and forth. This further facilitates the back and forth movement of the air nozzle 23. When the air nozzle 23 moves back and forth, the coverage area of ​​the ion air is no longer limited to a fixed area, but can act more evenly along the length of the fiber bundle, improving the contact between different parts of the fiber bundle and the ion air. The ions enhance the antistatic effect. Meanwhile, an insulating ceramic sleeve 24 is fitted on the outside of the lifting roller 25, and a conductive ceramic sleeve 6 is fitted on the outside of the insulating ceramic sleeve 24. A down conductor 12 is set on one side of the conductive ceramic sleeve 6, and a grounding plate 13 and a grounding steel pipe 14 are set at the end of the down conductor 12. The conductive ceramic sleeve 6 is in direct contact with the spinning process. It uses its conductivity to conduct the static electricity generated on the surface of the yarn bundle due to friction and separation to itself. The static electricity is transferred through the down conductor 12 to the grounding plate 13 and the grounding steel pipe 14, and finally conducted to the ground, realizing the rapid neutralization and release of static electricity, and ultimately improving the quality of the yarn bundle.
