Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a spinning tension regulating device. Background Art

[0002] Spinning is the process of processing polymer materials into continuous fibers through specific equipment. It is one of the core processes in the chemical fiber, textile, composite materials and other industries. During the spinning process, too little tension will cause the fiber to be understressed during stretching, while too much tension may cause the fiber to overstretch. In order to avoid this situation, a tension adjustment device is required.

[0003] The current spinning tension adjustment device has a poor anti-static effect during use. When the spinning passes through the tension adjustment component, static electricity is generated due to the pressure contact between the silk thread and the tension adjustment component. The static electricity will cause the silk thread to relax or burst when it extends out of the tension adjustment mechanism, and will also absorb dust in the air, affecting the color of the silk thread. Summary of the Invention

[0004] In order to solve the above technical deficiencies, the present invention provides a spinning tension regulating device, which can adjust the tension of fibers during the spinning process and effectively control the influence of static electricity generated during the fiber conveying process on the fibers.

[0005] The present invention discloses a spinning tension adjustment device, comprising a base, a bearing being provided at one end of the base, a winding roller being rotatably connected inside the bearing, a second motor being 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 being connected from top to bottom on the front side of the base relative to the other end of the bearing, a bottom plate being connected at the middle position of the front side of the base, a pair of electric push rods being connected above the bottom plate, a lifting plate being connected to the top end of the electric push rods, a pair of side plates being connected above the lifting plate, lifting rollers being connected to the inner sides of the side plates, and a first anti-static mechanism being provided on the outer sides of the lifting rollers.

[0006] The first anti-static mechanism includes a conductive ceramic sleeve, the inner wall of the conductive ceramic sleeve is connected to an insulating ceramic sleeve, the inner wall of the insulating ceramic sleeve is fixedly connected to the lifting roller, the outer side of the conductive ceramic sleeve is connected to a down conductor, the end of the down conductor is connected to a grounding plate, the bottom of the grounding plate is connected to a pair of grounding steel pipes, the down conductor is in contact with the conductive ceramic sleeve and can rotate relative to each other.

[0007] In order 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, and a second anti-static mechanism is provided inside the dust cover; the second anti-static mechanism includes an air distribution pipe, eight air nozzles are connected to the bottom of the air distribution pipe, and an air supply pipe is connected to the top of the air distribution pipe, one end of the air supply pipe passes through the top of the dust cover and is connected to an ion blower.

[0008] In order to expand the air supply 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 screw, one end of the reciprocating screw is rotatably connected to a bearing seat, the bearing seat is fixed on the dust cover, and the reciprocating screw is rotatably arranged inside the dust cover through the bearing seat and the first motor. A ball nut pair is connected to the top of the reciprocating screw, and a fixed sleeve is fixedly connected to the outside of the ball nut pair. The bottom of the fixed sleeve is fixedly connected to the air distribution pipe, and the air distribution pipe is slidably connected to the inner wall of the dust cover, and the air supply pipe is a hose.

[0009] The length of the air distribution pipe is consistent with the length of the lifting roller.

[0010] The eight air nozzles are symmetrically distributed left and right with the fixed sleeve as the center, and the air nozzles on the same side are evenly spaced.

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

[0012] By turning on the electric push rod, the height of the lifting roller on its top is raised, and the spinning is lifted upward from the middle to change the spinning tension. An insulating ceramic sleeve is set on the outside of the lifting roller, and a conductive ceramic sleeve is set 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, and uses its conductivity to conduct static electricity generated by friction and separation on the surface of the filament bundle to itself. The static electricity is transmitted to the grounding plate and the grounding steel pipe through the down conductor, and finally introduced into the earth, realizing the rapid neutralization and release of static electricity.

[0013] By turning on the ion blower, the ion wind can be sent into the air nozzle through the air supply pipe and the air distribution pipe, and then sprayed downward through the air nozzle, which is conducive to neutralizing the static electricity on the filament bundle through ions. At the same time, the first motor is turned on to facilitate driving the reciprocating screw to rotate, thereby driving the ball nut pair and the outer fixed sleeve to move back and forth, further facilitating the back and forth movement of the air nozzle. When the air nozzle moves back and forth, the coverage of the ion wind is no longer limited to a fixed area, and can act more evenly on the entire length direction of the filament bundle, thereby increasing the amount and uniformity of ions contacted by various parts of the filament bundle, and improving the anti-static effect.

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example 1:

[0020] like Figure 1-Figure 4 As shown, the present invention discloses a spinning tension adjustment device, including a base 4, a bearing 16 is provided at one end of the base 4, and a winding roller is rotatably connected inside the bearing 16. The back side of the base 4 is connected to a second motor 17, and 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 bottom 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 bottom plate 11, the top of the electric push rod 10 is connected to a lifting plate 9, and a pair of side plates 7 are connected above the lifting plate 9, the inner side of the side plate 7 is connected to a lifting roller 25, and the outer side of the lifting roller 25 is provided with a first anti-static mechanism.

[0021] In actual 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, achieving the winding of the spun yarn. The raising and lowering of the electric push rod 10 can push the lifting roller 25 on its top to rise and fall, changing the height position of the lifting roller 25, thereby lifting the spun yarn upward and ultimately changing the spinning tension. During the spinning operation, it is in contact with the lifting roller 25. The static electricity generated during the spinning process can be eliminated by the first anti-static mechanism, thereby preventing the impact of static electricity on the spinning and improving the spinning quality.

[0022] The first anti-static mechanism includes a conductive ceramic sleeve 6, the inner wall of which is connected to an insulating ceramic sleeve 24. The inner wall of the insulating ceramic sleeve 24 is fixedly connected to a lifting roller 25. The outer side of the conductive ceramic sleeve 6 is connected to a down conductor 12, the end of which is connected to a grounding plate 13, and the bottom of the grounding plate 13 is connected to a pair of grounding steel pipes 14. The down conductor 12 and the conductive ceramic sleeve 6 are in contact and can rotate relative to each other. The insulating ceramic sleeve 24 and the conductive ceramic sleeve 6 are sequentially coated on the outer side of the lifting roller 25. During the spinning process, the spinning yarn contacts the conductive ceramic sleeve 6. Static electricity generated during the spinning process is transferred to the conductive ceramic sleeve 6. The conductive ceramic sleeve 6 then transfers the static electricity to the ground through the down conductor 12, grounding plate 13, and grounding steel pipe 14, thereby eliminating the static electricity on the spinning yarn. The provision of the insulating ceramic sleeve 24 prevents static electricity from entering the lifting roller 25, the electric push rod 10, and other components, which could affect the normal operation of the equipment. In order to reduce the friction between the lifting roller 25 and the spinning, the lifting roller 25 can be set to be rotatable relative to the side plate 7, so the insulating ceramic sleeve 24 and the conductive ceramic sleeve 6 rotate with the lifting roller 25, and the down conductor 12 is fixed, so the down conductor 12 is in contact with the outside of the conductive ceramic sleeve 6, and the two can rotate freely. The two do not adopt a fixed connection form, so that the rotation of the conductive ceramic sleeve 6 will not drive the down conductor 12 to move, but the down conductor 12 is always in contact with the outside of the conductive ceramic sleeve 6, and can conduct static electricity to the ground.

[0023] In other embodiments, in order 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, and a second anti-static mechanism is provided inside the dust cover 2; the second anti-static mechanism includes an air distribution pipe 22, and eight air nozzles 23 are connected to the bottom of the air distribution pipe 22, and an air supply pipe 1 is connected to the top of the air distribution pipe 22, and one end of the air supply pipe 1 passes through the top of the dust cover 2 and is connected to an ion blower 15.

[0024] The design of the dust cover 2 can effectively isolate some dust from contacting the spinning. At the same time, the dust cover 2 can also serve as an installation carrier for the air distribution pipe 22. The ion blower 15 can transport the ion wind to the air nozzle 23 through the air supply pipe 1 and the air distribution pipe 22, and spray it downward through the air nozzle 23. The ion wind comes into contact with the spinning and neutralizes the static electricity on the yarn bundle through ions, so as to further enhance the elimination of static electricity on the yarn bundle.

[0025] In order to expand the air supply range of the ion wind, the outside of the dust cover 2 is connected to a first motor 3, 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, and the reciprocating screw 19 is rotatably arranged inside the dust cover 2 through the bearing seat 18 and the first motor 3. A ball nut pair 21 is connected to the top of the reciprocating screw 19, and a fixed sleeve 20 is fixedly connected to the outside of the ball nut pair 21. The bottom of the fixed sleeve 20 is fixedly connected to the air distribution pipe 22, and the air distribution pipe 22 is slidably connected to the inner wall of the dust cover 2, and the air supply pipe 1 is a hose.

[0026] A first motor 3 is mounted on one end of the dust cover 2, and a bearing seat 18 is fixedly mounted on the other end. A reciprocating screw 19 is disposed between the two. The reciprocating screw 19 is located within the dust cover 2 and above the lifting roller 25. The dust cover 2 and the lifting roller 25 are arranged vertically. A ball nut pair 21 is mounted on the reciprocating screw 19. The ball nut pair 21 is connected to the air distribution duct 22 via a fixed sleeve 20. The air distribution duct 22 is slidably connected to the inner wall of the dust cover 2. Therefore, when the reciprocating screw 19 rotates, the ball nut pair 21 cannot rotate and can only move on the reciprocating screw 19, thereby driving the reciprocating movement of the air distribution duct 22. Of course, the sliding direction between the air distribution duct 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 pair 21 are actually a ball screw nut pair. The sliding connection between the end of the air distribution duct 22 and the dust cover 2 can be achieved by providing a slide rail on the inner wall of the dust cover 2, and a slider on the end of the air distribution duct 22, with the slide rail and the slider cooperating to form a sliding connection. Because the reciprocating screw 19 drives the air distribution duct 22 to move back and forth, the connection point between the air distribution duct 22 and the air supply duct 1 will shift, so the air supply duct 1 is a 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, a slot can be provided in the dust cover 2 to allow the air distribution duct 1 to move and avoid interference between the air supply duct 1 and the dust cover 2.

[0027] The length of the air distribution duct 22 is consistent with that of the lifting roller 25. The eight air nozzles 23 are symmetrically distributed around the fixed sleeve 20, with nozzles 23 on the same side evenly spaced. This allows for a more uniform distribution of ionized air, allowing it to act evenly on the tow and effectively remove static electricity from the tow.

[0028] In this embodiment, by turning on the ion blower 15, the ion wind is conveniently sent into the air nozzle 23 through the air supply pipe 1 and the air distribution pipe 22, and then sprayed downward through the air nozzle 23, which is conducive to neutralizing the static electricity on the filament bundle through ions. At the same time, the first motor 3 is turned on to conveniently drive the reciprocating screw 19 to rotate, thereby driving the ball nut pair 21 and the outer fixed sleeve 20 to move back and forth, further facilitating the back and forth movement of the air nozzle 23. When the air nozzle 23 moves back and forth, the coverage of the ion wind is no longer limited to a fixed area, and can act more evenly in the length direction of the filament bundle, thereby improving the contact between various parts of the filament bundle and the air nozzle 23. ions, thereby improving the anti-static effect. At the same time, an insulating ceramic sleeve 24 is sleeved on the outside of the lifting roller 25, and a conductive ceramic sleeve 6 is sleeved 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, and uses its conductivity to conduct the static electricity generated on the surface of the filament bundle due to friction and separation to itself. The static electricity is transferred to the grounding plate 13 and the grounding steel pipe 14 through the down conductor 12, and finally introduced into the earth, so as to achieve rapid neutralization and release of static electricity, and finally improve the quality of the filament bundle.
