Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric winding technology, and more specifically, to an automatic nonwoven fabric winding mechanism. Background Technology

[0002] Nonwoven fabrics typically require a winding process after forming and drying for convenient subsequent transportation. Existing technologies, such as the one described in application number CN202411585988.2, involve clamping a hollow cylinder by moving opposing support plates during winding, then manually winding the nonwoven fabric around the cylinder, and finally stopping the winding process for unwinding. While this method completes the winding operation, it has the following drawbacks: 1. Each roll of nonwoven fabric requires a single-use hollow cylinder for winding, resulting in high winding costs; 2. Both the start and unwinding of winding require manual operation after the machine is stopped, leading to low automation, inability to seamlessly connect the winding process, and low winding efficiency. Summary of the Invention

[0003] To address the above deficiencies, this invention provides an automatic nonwoven fabric winding mechanism, which solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The nonwoven fabric automatic winding mechanism includes a fabric body, a transfer platform, a support frame, an air compressor, and a vacuum machine. The fabric body is available in two forms: wound and laid flat. The transfer platform pushes the fabric body to move horizontally. Motor 1, Motor 2, main shaft and expansion assembly. The expansion assembly is located on the main shaft. Motor 1 drives the main shaft to rotate on its own axis, and Motor 2 drives the main shaft to revolve around the central axis. The expansion assembly changes the diameter of the main shaft and generates negative pressure to actively attract the fabric body. The longitudinal beam and the tilting assembly are connected. The longitudinal beam moves in a circular motion, which drives the main shaft to move in a circular motion. The main shaft is connected to the longitudinal beam through the tilting assembly, which drives the main shaft to rotate 180 degrees. The unloading assembly removes the wound fabric body from the main shaft and transports the fabric body to the ground.

[0005] Furthermore, the tilting assembly is equipped with a rotary sealing valve one and a rotary sealing valve two, a driven wheel is installed at one end of the main shaft, and the output end of the motor one meshes with the driven wheel.

[0006] Furthermore, the expansion assembly includes an air bladder mounted on the surface of the spindle, a metal tube installed on the outer ring of the air bladder, the outer surface of the metal tube being flush with the outer surface of the air bladder, and a hole being provided on the outer surface of the metal tube; the air bladder is connected to a rotary sealing valve, and the metal tube is connected to a rotary sealing valve; the air compressor is connected to the rotary sealing valve, and the vacuum machine is connected to the rotary sealing valve.

[0007] Furthermore, the expansion assembly includes a bracket installed at the center of the spindle, with telescopic rods installed at both ends of the bracket. The telescopic ends of the telescopic rods extend out of the spindle, and an arc-shaped hollow tube is installed at the telescopic ends of the telescopic rods. The surface of the arc-shaped hollow tube has a second hole. A rotary sealing valve is connected to the telescopic rod, and a rotary sealing valve is connected to the arc-shaped hollow tube.

[0008] Furthermore, the tilting assembly includes a rotating shaft mounted on a bracket, a second motor mounted on the bracket that drives the rotating shaft to rotate, and longitudinal beams mounted on both sides of the rotating shaft. One end of the longitudinal beam has a notch, and bearings are mounted on both sides of the notch. A connecting shaft is mounted inside the bearings, and a swing tube is mounted on the connecting shaft. A worm gear assembly is provided on the side wall of the swing tube. A tilting motor is mounted on the longitudinal beam, and the tilting motor is connected to the swing tube through the worm gear assembly. One end of the swing tube has bearing two mounted on it, and one end of the main shaft is connected to the inner ring of bearing two.

[0009] Furthermore, the unloading assembly includes an electric slide rail hinged to the upper end of the bracket, a sliding block on the electric slide rail, connecting rods on both sides of the sliding block, an arc-shaped clamp plate on the connecting rod, and a hydraulic cylinder one installed between the connecting rod and the sliding block; a hydraulic cylinder two is installed between the electric slide rail and the bracket.

[0010] Furthermore, a transverse cutting blade is installed on the upper surface of the transfer platform.

[0011] Furthermore, the surface of the transfer platform is equipped with an active roller, which drives the fabric body to move horizontally.

[0012] Furthermore, the angle between the fabric's axis and the ground is greater than 50 degrees.

[0013] The beneficial effects of this invention are: the hollow cylinder is eliminated, and the nonwoven fabric is wound up by the main shaft and the expansion assembly.

The expansion components are provided in pairs. The expansion components work alternately to achieve seamless winding, avoid downtime, reduce the impact on production schedule, and improve winding efficiency. Attached Figure Description

[0015] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] This application provides an automatic nonwoven fabric winding mechanism; please refer to [reference needed]. Figures 1-7 It includes a fabric body 1, a transfer platform 2, a support 3, an air compressor 4, and a vacuum machine 5. The fabric body 1 is available in two forms: rolled and laid flat. The transfer platform 2 pushes the fabric body 1 to move horizontally. It also includes: Motor 6, Motor 7, Main shaft 8 and expansion component 9. The expansion component 9 is located on the main shaft 8. Motor 6 drives the main shaft 8 to rotate on its own axis, and Motor 7 drives the main shaft 8 to revolve around the sun. The expansion component 9 changes the diameter of the main shaft 8 and generates negative pressure to actively adsorb the fabric body 1. The longitudinal beam 10 and the tilting assembly 11 are connected together. The longitudinal beam 10 makes a circular motion, which drives the main shaft 8 to make a circular motion. The main shaft 8 is connected to the longitudinal beam 10 through the tilting assembly 11, and the tilting assembly 11 drives the main shaft 8 to rotate 180 degrees. The unloading assembly removes the wound fabric body 1 from the main shaft 8 and transports the fabric body 1 to the ground.

[0017] In practical applications, the air compressor 4 and vacuum machine 5 are based on existing technology and are used to generate negative and positive pressure; the transfer platform 2 can actively transport the flat fabric body 1, and the expansion component 9 is initially in an expanded state. The horizontal cutting blade 71 can cut the flat fabric body 1. After cutting, the cut position of the fabric body 1 is moved below the main shaft 8 and the expansion assembly 9, as shown below. Figure 1 As shown, at this time, the motor 6 drives the main shaft 8 and the expansion component 9 to rotate, while controlling the expansion component 9 to generate negative pressure, so as to achieve the purpose of actively adsorbing the fabric body 1. After the fabric body 1 is attached to the expansion component 9, the main shaft 8 rotates and rolls the flat fabric body 1 onto the expansion component 9. Then the longitudinal beam 10 swings counterclockwise by 45 degrees, raising the height of the main shaft 8. This position is the normal winding position. After winding is completed, the wound fabric body 1 swings counterclockwise 135 degrees and moves to the top of the unloading assembly, and then the unloading operation is performed. While the rolled-up fabric body 1 swings counterclockwise by 135 degrees, the horizontal cutting blade 71 cuts the flat fabric body 1 again. The other main shaft 8 moves along the cutting position on the flat fabric body 1 until it sucks the fabric body 1 up again. Repeat the above operation, the main shaft 8 can rotate counterclockwise intermittently, and in conjunction with the work of the unloading component, achieve the purpose of continuous automatic winding of the fabric body 1 without stopping the machine.

[0018] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 The flipping assembly 11 is equipped with a rotary sealing valve 21 and a rotary sealing valve 22. A driven wheel 23 is installed at one end of the main shaft 8, and the output end of the motor 6 meshes with the driven wheel 23.

[0019] In practical applications, the rotation of motor 6 can drive the driven wheel 23 and the main shaft 8 to rotate. Through the setting of rotary sealing valve 21 and rotary sealing valve 22, the air compressor 4 and vacuum machine 5 can deliver air pressure while the main shaft 8 and expansion assembly 9 always rotate in one direction.

[0020] Example 1 of expansion component 9, see below Figure 1 , Figure 2 , Figure 3 and Figure 6 The expansion assembly 9 includes an air bladder 31 mounted on the surface of the spindle 8. A metal tube 32 is installed on the outer ring of the air bladder 31. The outer surface of the metal tube 32 is flush with the outer surface of the air bladder 31. A hole 33 is provided on the outer surface of the metal tube 32. The air bladder 31 is connected to a rotary sealing valve 21, and the metal tube 32 is connected to a rotary sealing valve 22. The air compressor 4 is connected to the rotary sealing valve 21, and the vacuum machine 5 is connected to the rotary sealing valve 22.

[0021] In practical applications, the air compressor 4 delivers high-pressure gas to the rotary sealing valve 21, at which point the air bag 31 is inflated and its diameter increases. The vacuum machine 5 delivers negative pressure to the rotary sealing valve 22, at which point there is negative pressure in the metal tube 32 and the hole 33. When the flat fabric body 1 comes into contact with the hole 33, the negative pressure can be used to tighten the fabric body 1. When the main shaft 8 and the air bag 31 rotate, the fabric body 1 can be wound around the air bag 31. After the wound fabric body 1 moves to the position of the unloading assembly, the vacuum machine 5 stops working, the air bag 31 exhausts, and the diameter of the air bag 31 decreases, making it easier to remove the unloading assembly.

[0022] Example 2 of expansion component 9, see below Figure 1 , Figure 2 , Figure 4 and Figure 7 The expansion assembly 9 includes a support rod 44 installed at the center of the main shaft 8. Telescopic rods 41 are installed at both ends of the support rod 44. The telescopic ends of the telescopic rods 41 extend out of the main shaft 8. An arc-shaped hollow tube 42 is installed at the telescopic ends of the telescopic rods 41. A second hole 43 is opened on the surface of the arc-shaped hollow tube 42. A first rotary sealing valve 21 is connected to the telescopic rod 41, and a second rotary sealing valve 22 is connected to the arc-shaped hollow tube 42.

[0023] In practical applications, the extension rod 41 extends and drives the arc-shaped hollow tube 42 to move in the opposite direction. At this time, the diameter of the arc-shaped hollow tube 42 and the circle formed by it increases. The arc-shaped hollow tube 42 is equipped with negative pressure, which can suck up the fabric body 1 and finally form the fabric body 1 in a rolled state. The extension rod 41 can be shortened to drive the arc-shaped hollow tube 42 to move in opposite directions. The diameter of the arc-shaped hollow tube 42 and the circle formed by them becomes smaller, which makes it easier for the fabric body 1 to detach.

[0024] Reference Figures 1 to 5 The flipping assembly 11 includes a rotating shaft 51 mounted on a bracket 3, a second motor 7 mounted on the bracket 3, and the second motor 7 drives the rotating shaft 51 to rotate. A longitudinal beam 10 is mounted on both sides of the rotating shaft 51. One end of the longitudinal beam 10 has a notch 53, and bearings 54 are mounted on both sides of the notch 53. A connecting shaft 55 is mounted inside the bearings 54, and a swing tube 56 is mounted on the connecting shaft 55. A worm gear assembly 57 is provided on the side wall of the swing tube 56. A flipping motor 58 is mounted on the longitudinal beam 10, and the flipping motor 58 is connected to the swing tube 56 through the worm gear assembly 57. One end of the swing tube 56 is mounted with a second bearing 59, and one end of the main shaft 8 is connected to the inner ring of the second bearing 59.

[0025] In practical applications, the rotation of motor 7 can drive the rotating shaft 51 and the longitudinal beam 10 to rotate counterclockwise. The flipping motor 58 drives the swing tube 56, the main shaft 8 and the expansion assembly 9 to rotate 180 degrees through the worm gear assembly 57, which facilitates the swing of the main shaft 8 between the winding station and the unloading station.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The unloading assembly includes an electric slide rail 60 hinged to the upper end of the bracket 3, a sliding block 61 on the electric slide rail 60, connecting rods 62 on both sides of the sliding block 61, an arc-shaped clamping plate 63 on the connecting rods 62, and a hydraulic cylinder 64 between the connecting rods 62 and the sliding block 61; and a hydraulic cylinder 65 between the electric slide rail 60 and the bracket 3.

[0027] In practical applications, after the wound fabric body 1 moves to the unloading assembly, the hydraulic cylinder 64 extends and drives the arc-shaped clamping plate 63 to clamp the fabric body 1 through the connecting rod 62. Then, the sliding block 61 is controlled to slide away from the longitudinal beam 10. When the wound fabric body 1 is completely separated from the main shaft 8, the hydraulic cylinder 65 is controlled to shorten, so that the wound fabric body 1 gradually moves to the ground and is removed manually.

[0028] Reference Figure 1 A transverse cutting blade 71 is installed on the upper surface of the transfer platform 2.

[0029] In practical applications, the transverse cutting blade 71 can cut the fabric body 1.

[0030] Reference Figure 1 The surface of the transfer platform 2 is equipped with an active roller 81, which drives the fabric body 1 to move horizontally.

[0031] In practical applications, the active roller 81 can rotate to drive the fabric body 1 to move.

[0032] Reference Figures 1 to 7 The angle between the axis of the fabric body 1 and the ground is greater than 50 degrees.

[0033] In practical applications, after the arc-shaped clamp 63 releases the fabric body 1, the fabric body 1 is in an inclined state. When the angle between the axis of the fabric body 1 and the ground is greater than 50 degrees, the axis of the fabric body 1 automatically stands up under the action of gravity, which is convenient for manual movement.
