Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric production technology, specifically a nonwoven fabric production turning and rolling device. Background Technology

[0002] With the improvement of people's living standards, waterproof and breathable fabrics are becoming increasingly popular due to their waterproof, breathable, insulating, windproof, and warm properties. Waterproof and breathable fabrics are made of a composite material of high-polymer waterproof and breathable materials (PTFE membrane) and fabric. While enhancing the airtightness and watertightness of the fabric, they possess unique breathability, allowing moisture inside the structure to quickly escape, preventing mold growth and keeping the body dry. This perfectly solves the problems of breathability, windproofness, waterproofing, and warmth, making it a healthy and environmentally friendly new type of fabric. In the non-woven fabric production process, the rewinding process is a crucial step. Its main function is to rewind the completed non-woven fabric rolls according to certain specifications and requirements for subsequent storage.

[0003] In the existing technology, the folding equipment does not have the function of eliminating wrinkles. After folding, the fibers in the wrinkled area will undergo irreversible plastic deformation. Even if it is unfolded later, clear and difficult-to-eliminate creases will remain in the deformed area, which directly affects the product quality.

[0004] Therefore, this utility model provides a turning and rolling device for nonwoven fabric production. Utility Model Content

[0005] To address the shortcomings of existing technology and solve the problem that the folding equipment does not have the function of eliminating wrinkles, the fibers in the folded area will undergo irreversible plastic deformation after folding. Even if it is unfolded later, clear and difficult-to-eliminate creases will remain in the deformed area, which directly affects the product quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A nonwoven fabric production turning and rolling device according to this utility model includes a base plate, and a turning and rolling mechanism is provided on the base plate. The turning and rolling mechanism includes: A winding assembly, mounted on the base plate, is used to wind up the nonwoven fabric. The flattening assembly includes a pair of first sliding grooves on a base plate, a sliding plate slidably connected in the first sliding grooves, a first rotating rod rotatably connected between the opposite sidewalls of the pair of sliding plates, and the two ends of the first rotating rod passing through the sidewalls of the pair of sliding plates respectively. A fixed roller is fixedly connected to the first rotating rod, and a pair of spiral rings are fixedly connected to the fixed rollers, with the pair of spiral rings arranged opposite to each other. A guide roller is fixedly connected between the opposite sidewalls of the pair of sliding plates. A linkage assembly for driving the first rotating rod to rotate is provided on the first rotating rod. Auxiliary components are installed on the base plate to assist in winding.

[0007] Preferably, the winding assembly includes a pair of fixed plates fixed to the top of the base plate, a second rotating rod rotatably connected to the fixed plates through a first rotating hole, a winding roller connected between the pair of second rotating rods through a disassembly unit, an L-shaped plate fixed to the side wall of the fixed plate, a motor fixed to the vertical side wall of the L-shaped plate, and the output end of the motor being drivenly connected to the second rotating rod.

[0008] Preferably, the linkage assembly includes a first bevel gear fixedly connected to a first rotating rod, a first L-shaped block rotatably connected to the first rotating rod, an electric actuator rotatably connected to the first L-shaped block through a second rotating hole, a second bevel gear fixedly connected to the base end of the electric actuator, and the second bevel gear meshing with the first bevel gear.

[0009] Preferably, a second L-shaped block is rotatably connected to the second rotating rod, and the second L-shaped block is rotatably connected to the telescopic end of the electric actuator through a third rotating hole. A third bevel gear is fixedly connected to the telescopic end of the electric actuator, and a fourth bevel gear is fixedly connected to the second rotating rod. The third bevel gear and the fourth bevel gear are meshed together.

[0010] Preferably, the auxiliary component includes a support plate fixedly connected to the side wall of a fixed plate, a second sliding groove is provided on the side wall of the support plate, a sliding block is slidably connected in the second sliding groove, and a first rectangular plate is fixedly connected between the opposite side walls of a pair of sliding blocks.

[0011] Preferably, a pair of rectangular blocks are fixed to the side wall of the first rectangular plate, and a rotating roller is rotatably connected between the opposite side walls of the pair of rectangular blocks. A second rectangular plate is fixed between the pair of support plates, and a pair of elastic telescopic rods are fixed to the side wall of the second rectangular plate. The telescopic ends of the elastic telescopic rods are fixed to the side wall of the first rectangular plate.

[0012] The beneficial effects of this utility model are as follows: 1. The nonwoven fabric production turning and rolling equipment described in this utility model uses relatively arranged spiral rings to generate a pushing force to both sides through rotation, which can effectively flatten the nonwoven fabric, avoid wrinkles, ensure the surface of the nonwoven fabric after winding, improve the product appearance and the convenience of subsequent processing, and adjust the tension of the nonwoven fabric through an electric push rod to avoid wrinkles caused by tension issues. This solves the problem in the prior art that the turning and rolling equipment does not have the function of eliminating wrinkles. After turning and rolling, the fibers in the wrinkled area will undergo irreversible plastic deformation. Even if it is unfolded later, clear and difficult-to-eliminate creases will still remain in the deformed area, which directly affects the product quality.

[0013] 2. The nonwoven fabric production turning and rolling device described in this utility model uses the elastic force of the elastic telescopic rod to continuously push the rotating roller to press the nonwoven fabric roll tightly. As the diameter of the nonwoven fabric roll on the winding roller gradually increases, the rotating roller slides upward along the second sliding groove through the sliding block, and the elastic telescopic rod extends synchronously to maintain stable pressure on the nonwoven fabric roll, avoiding wrinkles or displacement due to loosening during the winding process, and ensuring consistent winding tightness.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4As shown in the figure, a nonwoven fabric production turning and rolling device according to an embodiment of the present invention includes a base plate 1, which serves as the basic supporting component of the device. A turning and rolling mechanism is provided on the base plate 1. The turning and rolling mechanism includes: a winding assembly, which is provided on the base plate 1 for winding nonwoven fabric; a flattening assembly, which includes a pair of first sliding grooves 2 opened on the base plate 1 as tracks for adjusting tension. A sliding plate 3 is slidably connected in the first sliding groove 2. A first rotating rod 4 is rotatably connected between the opposite side walls of the pair of sliding plates 3, and the two ends of the first rotating rod 4 pass through the side walls of the pair of sliding plates 3 respectively. A fixed roller 5 is fixedly connected to the first rotating rod 4, and a pair of spiral rings 6 are fixedly connected to the fixed roller 5. The pair of spiral rings 6 are arranged opposite to each other, and the spiral rings 6 on their surfaces directly act on the nonwoven fabric to achieve the flattening function. A guide roller 7 is fixedly connected between the opposite side walls of the pair of sliding plates 3; a linkage assembly is provided on the first rotating rod 4 for driving the first rotating rod 4 to rotate; and an auxiliary assembly, which is provided on the base plate 1 for assisting in winding.

[0018] The winding assembly includes a pair of fixed plates 8 fixed to the top of the base plate 1, which are vertically fixed to the top two sides of the base plate 1. A second rotating rod 9 is rotatably connected to the fixed plate 8 through a first rotating hole. A winding roller 10 is connected between the pair of second rotating rods 9 through a disassembly unit. An L-shaped plate 11 is fixed to the side wall of the fixed plate 8. A motor 12 is fixed to the vertical side wall of the L-shaped plate 11. As the power source of the winding assembly, the motor 12 is a servo motor. The output end of the motor 12 is driven and connected to the second rotating rod 9.

[0019] The linkage assembly includes a first bevel gear 13 fixedly connected to the first rotating rod 4, a first L-shaped block 14 rotatably connected to the first rotating rod 4, an electric push rod 15 rotatably connected to the first L-shaped block 14 through a second rotating hole, a second bevel gear 16 fixedly connected to the base end of the electric push rod 15, the second bevel gear 16 meshing with the first bevel gear 13, and the first bevel gear 13 and the second bevel gear 16 being the same size.

[0020] A second L-shaped block 17 is rotatably connected to the second rotating rod 9. The second L-shaped block 17 is rotatably connected to the telescopic end of the electric push rod 15 through the third rotating hole. A third bevel gear 18 is fixedly connected to the telescopic end of the electric push rod 15. A fourth bevel gear 19 is fixedly connected to the second rotating rod 9. The third bevel gear 18 and the fourth bevel gear 19 are meshed and connected. The third bevel gear 18 and the fourth bevel gear 19 are the same size.

[0021] During operation, the rotating spiral rings 6 generate a pushing force to both sides, which effectively flattens the non-woven fabric, avoids wrinkles, ensures a smooth surface after winding, improves product appearance and ease of subsequent processing, and allows for adjustment of the non-woven fabric tension via the electric push rod 15 to prevent wrinkles caused by tension issues. This solves the problem in existing technologies where the winding equipment does not have the function of eliminating wrinkles, and the fibers in the wrinkled area undergo irreversible plastic deformation after winding. Even if it is unwound later, clear and difficult-to-eliminate creases remain in the deformed area, directly affecting product quality.

[0022] The auxiliary component includes a support plate 20 fixed to the side wall of a fixed plate 8, which provides installation support for other components of the auxiliary component. The side wall of the support plate 20 has a second sliding groove 21, and a sliding block 22 is slidably connected in the second sliding groove 21. A first rectangular plate 23 is fixed between a pair of sliding blocks 22 and opposite side walls.

[0023] A pair of rectangular blocks 24 are fixed to the side wall of the first rectangular plate 23. A rotating roller 25 is rotatably connected between the opposite side walls of the pair of rectangular blocks 24. A second rectangular plate 26 is fixed between a pair of support plates 20. A pair of elastic telescopic rods 27 are fixed to the side wall of the second rectangular plate 26. Their elasticity always pushes the first rectangular plate 23 to drive the rotating roller 25 to press the nonwoven fabric roll. The telescopic end of the elastic telescopic rod 27 is fixed to the side wall of the first rectangular plate 23.

[0024] During operation, the elastic force of the elastic telescopic rod 27 continuously pushes the rotating roller 25 to press the nonwoven fabric roll tightly. As the diameter of the nonwoven fabric roll on the take-up roller 10 gradually increases, the rotating roller 25 slides upward along the second sliding groove 21 through the sliding block 22, and the elastic telescopic rod 27 extends synchronously to maintain stable pressure on the nonwoven fabric roll, avoid wrinkles or deviations caused by loosening during the take-up process, and ensure consistent take-up tightness.

[0025] Working principle: Start motor 12, the output of motor 12 drives the second rotating rod 9 in the winding assembly to rotate. The winding roller 10, connected between a pair of second rotating rods 9 via the disassembly unit, rotates synchronously with the second rotating rods 9, preparing to wind up the nonwoven fabric. At this time, one end of the nonwoven fabric is pre-fixed on the winding roller 10, forming the winding starting point. The nonwoven fabric passes through the bottom of the guide roller 7, through the gap between the guide roller 7 and the fixed roller 5, and is wound around the fixed roller 5.

[0026] When the second rotating rod 9 rotates, the fourth bevel gear 19 fixed to it rotates synchronously. Since the third bevel gear 18 at the telescopic end of the electric push rod 15 meshes with the fourth bevel gear 19, the third bevel gear 18 rotates with the fourth bevel gear 19, thereby driving the electric push rod 15 to rotate as a whole. The second bevel gear 16 at the base end of the electric push rod 15 meshes with the first bevel gear 13 on the first rotating rod 4, thus driving the first rotating rod 4 to rotate. The fixed roller 5 and spiral ring 6 fixed to the first rotating rod 4 rotate together, flattening while winding. Simultaneously, the electric push rod 15 is connected to the second rotating rod 9 via the second L-shaped block and the first L-shaped block... The shape block is connected to the first rotating rod 4, which can be adjusted to adapt to changes in the tension of the nonwoven fabric during the winding process, avoiding wrinkles and ensuring that the bevel gear always remains in mesh to ensure the continuity of power transmission. A pair of spiral rings 6 on the fixed roller 5 are arranged opposite each other (i.e., the spiral directions are opposite). When the fixed roller 5 rotates, the spiral rings 6 exert a pushing force on the nonwoven fabric passing over its surface to both sides, stretching the edges of the nonwoven fabric to both sides, achieving automatic flattening and avoiding wrinkles during the winding process.
