Technical Field

[0001] This invention relates to the field of nonwoven fabric winding technology, specifically to a nonwoven fabric winding device for nonwoven fabric machinery. Background Technology

[0002] Nonwoven fabric (also known as non-woven cloth) is a flexible fiber product that does not require spinning and weaving. With its advantages of high production efficiency, low cost and customizable functions, it has been widely used in medical protection (masks, surgical gowns), hygiene products (diapers, wipes), industrial packaging, agricultural covering and other fields. In traditional equipment, impurities on the surface of nonwoven fabric are difficult to clean due to static electricity generated by friction during winding. Static electricity can also cause wrinkles in the nonwoven fabric during winding, thus affecting subsequent processing of the nonwoven fabric. Summary of the Invention

At the same time, the antistatic liquid can enhance the conductivity of the fabric, allowing static electricity to be released quickly and avoiding accumulation. This prevents static electricity accumulation from causing the fabric to attract dust and impurities, which would affect the cleanliness of the product.

A nozzle is installed on one side of each of the two sets of liquid storage tanks. A support frame is installed on one side of both the first support base and the second support base. A first limiting roller and a second limiting roller are respectively installed inside the support frame. A gear is meshed on one side of the half gear. A knocking rod is connected to the other end of the gear. A spring rod is connected to the other end of the knocking rod.

[0005] Preferably, a motor A is installed at one end of the base, and a groove is formed on the upper surface of the base. A threaded rod is provided inside the groove. One end of the threaded rod passes through the base and is connected to the output end of the motor A. A first support seat and a second support seat are threadedly connected to the outside of the threaded rod.

[0006] Preferably, a motor B is fixedly connected to one end of the first support base, and a rotating shaft A is connected to the output end of the motor B. The rotating shaft A extends through the first support base to the other end of the first support base. A protrusion is fixedly connected to the end of the rotating shaft A away from the motor B, and the size of the first support base matches the size of the snap-fit ​​groove.

[0007] Preferably, the end of the half gear near the second support is connected to a rotating shaft B, the other end of the rotating shaft B extends through the second support to the other end, the end of the rotating shaft B away from the half gear is connected to a protrusion, and the size of the rotating shaft B matches the snap-fit ​​groove.

[0008] Preferably, the support frame internally connects the first limiting roller and the second limiting roller, and both the first limiting roller and the second limiting roller are made of stainless steel, and the first limiting roller and the second limiting roller have the same length.

[0009] Preferably, the reciprocating lead screw is connected to the piston ball nut assembly, and the other end of the guide tube is connected to a connecting pipe, the other end of the connecting pipe is connected to a storage tank, the other end of the storage tank is connected to a flexible hose, the guide tube has a guide groove, and the piston is limited by a sliding groove.

[0010] Preferably, the other end of the hose is connected to two sets of liquid storage tanks, and multiple sets of nozzles are fixedly connected to the opposite side of each of the two sets of liquid storage tanks.

[0011] Preferably, a second fixed frame is fixedly connected to one side of the support frame, and a gear is rotatably connected to the other end of the second fixed frame. The end of the gear away from the second fixed frame is fixedly connected to the knocking rod.

[0012] Preferably, a first fixing frame is fixedly connected to the other side of the support frame, and the other end of the first fixing frame is connected to the spring rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: When using this invention, an antistatic liquid is sprayed onto both sides of the nonwoven fabric to eliminate static electricity, making the separation between fabric layers smoother, the winding neater, reducing wrinkles and damage, and preventing static electricity from causing the nonwoven fabric to attract each other, which can easily lead to interlayer adhesion, misalignment, or uneven winding during winding. At the same time, the antistatic liquid can enhance the conductivity of the fabric, allowing static electricity to be released quickly and avoiding accumulation. This prevents static electricity accumulation from causing the fabric to attract dust and impurities, which would affect the cleanliness of the product.

[0014] This invention applies a certain amount of beating pressure to the nonwoven fabric during winding, thereby causing small wrinkles at the edges of the nonwoven fabric due to uneven tension during the transmission of the nonwoven fabric by the guide roller. The impact force of the beating can flatten the fibers at the wrinkles, making the fabric surface smoother and avoiding wrinkles after winding. At the same time, the beating can appropriately loosen the fibers, preventing the nonwoven fabric with some tightly packed fibers or local compaction from affecting subsequent unfolding or processing after winding.

[0015] In this invention, when the nonwoven fabric is patted, the surface of the nonwoven fabric contains a certain amount of antistatic liquid. The antistatic liquid itself can eliminate static electricity, and the patting action further helps to release residual static electricity. The wet surface combined with the patting vibration can more effectively prevent the fabric from sticking together due to static electricity or adsorption. At the same time, the mechanical vibration during patting, combined with the antistatic liquid, breaks the electrostatic adsorption between floating dust and residual fibers and the surface of the nonwoven fabric, causing impurities to fall off the fabric surface, thereby making the nonwoven fabric surface cleaner and improving product quality.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-7 The present invention provides a nonwoven fabric winding device for nonwoven fabric machinery, including a first support seat 4 and a second support seat 7 that slide on the upper end of a base 1. A winding roller 26 is rotatably disposed between the first support seat 4 and the second support seat 7. The winding roller 26 has locking grooves at both ends. A half gear 9 is rotatably disposed at one end of the second support seat 7. A guide tube 11 is disposed at one end of the half gear 9. A reciprocating screw 10 is rotatably disposed inside the guide tube 11, and a piston 12 that slides inside the guide tube 11 and reciprocates along the outside of the reciprocating screw 10. One end of the guide tube 11 is connected to the storage tank 14, and the other end of the storage tank 14 is connected to two sets of liquid storage tanks 24. A nozzle 25 is installed on one side of each set of liquid storage tanks 24. A support frame 15 is installed on one side of both the first support base 4 and the second support base 7. The first limiting roller 21 and the second limiting roller 22 are respectively installed inside the support frame 15. A gear 20 is meshed on one side of the half gear 9. A knocking rod 18 is connected to the other end of the gear 20. A spring rod 17 is connected to the other end of the knocking rod 18.

[0020] In an optional embodiment, a motor A2 is installed at one end of the base 1, and a groove is formed on the upper surface of the base 1. A threaded rod 3 is provided inside the groove. One end of the threaded rod 3 passes through the base 1 and is connected to the output end of the motor A2. A first support seat 4 and a second support seat 7 are threadedly connected to the outside of the threaded rod 3. In use, the operator places the take-up roller 26 between the first support seat 4 and the second support seat 7. At this time, the motor A2 drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, it drives the first support seat 4 and the second support seat 7 to move towards the center, thereby fixing the take-up roller 26.

[0021] In an optional embodiment, a motor B5 is fixedly connected to one end of the first support base 4, and a rotating shaft A6 is connected to the output end of the motor B5. The rotating shaft A6 extends through the first support base 4 to the other end of the first support base 4. A protrusion is fixedly connected to the end of the rotating shaft A6 away from the motor B5, and the size of the first support base 4 matches the size of the snap-fit ​​groove. As described above, when the first support base 4 moves, it will synchronously drive the motor B5 and the rotating shaft A6 to move. When the first support base 4 contacts the take-up roller 26, the rotating shaft A6 will enter the snap-fit ​​groove. After the take-up roller 26 is fixed, the operator pulls the nonwoven fabric to be rolled up to the outer wall of the take-up roller 26 to roll it up and fix it. At this time, the motor B5 is started. After the motor B5 is started, the motor B5 will drive the rotating shaft A6 to rotate. When the rotating shaft A6 rotates, it will synchronously drive the take-up roller 26 to rotate, so that when the take-up roller 26 rotates, it will automatically roll up the nonwoven fabric.

[0022] In an optional embodiment, a rotating shaft B8 is connected to one end of the half gear 9 near the second support 7. The other end of the rotating shaft B8 extends through the second support 7 to the other end. A protrusion is connected to the end of the rotating shaft B8 away from the half gear 9. The size of the rotating shaft B8 matches the snap-fit ​​groove. When the rotating shaft A6 enters the snap-fit ​​groove, the rotating shaft B8 will enter the snap-fit ​​groove simultaneously. As mentioned above, when the take-up roller 26 rotates, it will drive the rotating shaft B8 to rotate simultaneously. When the rotating shaft B8 rotates, it will drive the half gear 9 to rotate simultaneously.

[0023] In an optional embodiment, the support frame 15 internally rotatably connects the first limiting roller 21 and the second limiting roller 22, both of which are made of stainless steel and have the same length. Before the nonwoven fabric is wound onto the winding roller 26, the operator wraps the nonwoven fabric around the outer surface of the first limiting roller 21 and the second limiting roller 22 in an alternating manner, so that the nonwoven fabric is stretched alternately by the first limiting roller 21 and the second limiting roller 22 during winding, thereby improving and reducing wrinkles on the surface of the nonwoven fabric.

[0024] In an optional embodiment, the reciprocating screw 10 is connected to the piston 12 ball nut assembly, and the other end of the guide tube 11 is connected to the connecting tube 13. The other end of the connecting tube 13 is connected to the storage tank 14, and the other end of the storage tank 14 is connected to the hose 23. The guide tube 11 has a guide groove, and the piston 12 is limited by the slide groove. When the half gear 9 rotates, it will synchronously drive the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, it will drive the piston 12 to reciprocate inside the guide tube 11. When the piston 12 reciprocates, it will continuously deliver gas to the inside of the connecting tube 13. The storage tank 14 stores antistatic liquid cationic quaternary ammonium salt spray liquid. After the gas enters the inside of the connecting tube 13, it will be delivered to the inside of the storage tank 14 through the connecting tube 13, thereby squeezing the antistatic liquid inside the storage tank 14 into the hose 23.

[0025] In an optional embodiment, the other end of the hose 23 is connected to two sets of liquid storage tanks 24. Multiple sets of nozzles 25 are fixedly connected to opposite sides of each set of liquid storage tanks 24. After the antistatic liquid enters the hose 23, it enters the liquid storage tanks 24. As the antistatic liquid gradually enters the liquid storage tanks 24, it is squeezed through the multiple sets of nozzles 25 and sprayed in an atomized form onto both sides of the nonwoven fabric. The amount sprayed by the nozzles 25 is small, preventing the antistatic liquid from penetrating into the nonwoven fabric. Thus, when the antistatic liquid is sprayed onto both sides of the nonwoven fabric, static electricity is eliminated, resulting in smoother separation between fabric layers, neater winding, reduced wrinkles and damage, and prevention of static electricity causing the nonwoven fabric to adhere to each other, which can easily lead to interlayer adhesion, misalignment, or uneven winding during winding. Simultaneously, the antistatic liquid enhances the conductivity of the fabric, allowing static electricity to be released quickly and preventing accumulation. This prevents static electricity accumulation from causing the fabric to attract dust and impurities, affecting product cleanliness.

[0026] In an optional embodiment, a second fixed frame 19 is fixedly connected to one side of the support frame 15, and a gear 20 is rotatably connected to the other end of the second fixed frame 19. The end of the gear 20 away from the second fixed frame 19 is fixedly connected to the knocking rod 18. When the half gear 9 rotates, it will drive the gear 20 to rotate synchronously. Since the half gear 9 is a half tooth, after the half gear 9 rotates and drives the gear 20 to rotate a certain angle, the half gear 9 will disengage from the gear 20. When the gear 20 rotates, it will drive the knocking rod 18 to flip synchronously.

[0027] In an optional embodiment, a first fixed frame 16 is fixedly connected to the other side of the support frame 15. The other end of the first fixed frame 16 is connected to the spring rod 17. As described above, when the knocking rod 18 flips, it will synchronously drive the spring rod 17 to rotate. Then, when the half gear 9 disengages from the gear 20, the knocking rod 18 will fall due to its own weight. When the half gear 9 disengages from the gear 20, as the knocking rod 18 falls, the spring rod 17 will apply a certain flipping speed to the knocking rod 18 as it resets, thereby making the knocking rod 18 quickly reset. When the knocking rod 18 resets, it will apply a certain patting pressure to the nonwoven fabric. As a result, small wrinkles appear at the edges of the nonwoven fabric due to uneven tension during the transmission of the guide roller. The impact force of the patting can flatten the fibers at the wrinkles, making the fabric surface flatter and avoiding wrinkles after winding. At the same time, the patting can loosen the fibers appropriately, avoiding the nonwoven fabric with some fibers being too tight or having local compaction after winding from affecting subsequent unfolding or processing. Furthermore, when the nonwoven fabric is patted, the surface of the nonwoven fabric contains a certain amount of antistatic liquid. The antistatic liquid itself can eliminate static electricity, and the patting action further helps to release residual static electricity. The wet surface combined with the patting vibration can more effectively prevent the fabric from sticking together due to static electricity or adsorption. At the same time, the mechanical vibration during patting, combined with the antistatic liquid, will break the static adsorption between floating dust and residual fibers and the surface of the nonwoven fabric, causing impurities to fall off the fabric surface, thus making the nonwoven fabric surface cleaner and improving product quality.

[0028] Working principle: During use, the operator places the take-up roller 26 between the first support seat 4 and the second support seat 7. At this time, the threaded rod 3 is driven to rotate by the motor A2. When the threaded rod 3 rotates, it drives the first support seat 4 and the second support seat 7 to move towards the center. When the first support seat 4 moves, it simultaneously drives the motor B5 and the rotating shaft A6 to move. When the first support seat 4 contacts the take-up roller 26, the rotating shaft A6 will enter the engagement groove. When the rotating shaft A6 enters the engagement groove, it simultaneously drives the rotating shaft B8 to move. Entering the snap-fit ​​groove, the take-up roller 26 is fixed. After the take-up roller 26 is fixed, the operator wraps the non-woven fabric to be rolled up around the outer surface of the first limiting roller 21 and the second limiting roller 22 in an alternating manner. Then, the non-woven fabric is pulled to the outer wall of the take-up roller 26 and rolled up and fixed. At this time, the motor B5 is started. After the motor B5 is started, the motor B5 will drive the rotating shaft A6 to rotate. When the rotating shaft A6 rotates, it will synchronously drive the take-up roller 26 to rotate. Thus, when the take-up roller 26 rotates, it will automatically roll up the non-woven fabric. When the take-up roller 26 rotates, it synchronously drives the rotating shaft B8 to rotate. When the rotating shaft B8 rotates, it synchronously drives the half gear 9 to rotate. When the half gear 9 rotates, it synchronously drives the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, it drives the piston 12 to move back and forth inside the guide tube 11. When the piston 12 moves back and forth, it continuously delivers gas into the connecting tube 13. The storage tank 14 stores antistatic liquid cationic quaternary ammonium salt spray liquid. After the gas enters the connecting tube 13, it is delivered to the storage tank 14 through the connecting tube 13, thereby squeezing the antistatic liquid in the storage tank 14 into the hose 23. After the antistatic liquid enters the hose 23, it enters the liquid storage tank 24. At this time, as the antistatic liquid gradually enters the liquid storage tank 24, it squeezes the antistatic liquid through multiple sets of nozzles 25 and sprays it onto both sides of the nonwoven fabric in an atomized form. When half gear 9 rotates, it synchronously drives gear 20 to rotate. Since half gear 9 is a half tooth, after half gear 9 rotates and drives gear 20 to rotate a certain angle, half gear 9 will disengage from gear 20. When gear 20 rotates, it synchronously drives knocking rod 18 to rotate. When knocking rod 18 rotates, it synchronously drives spring rod 17 to rotate. When half gear 9 disengages from gear 20, knocking rod 18 will fall due to its own weight. When half gear 9 disengages from gear 20, as knocking rod 18 falls, spring rod 17 will apply a certain rotation speed to knocking rod 18 as it returns to its original position, thus causing knocking rod 18 to quickly return to its original position. When knocking rod 18 returns to its original position, it will apply a certain striking pressure to the nonwoven fabric.
