Description

Technical Field

[0001] This invention relates to a thin fabric feeding device for a warp knitting fabric splitting machine, belonging to the field of splitting machine technology. Background Technology

[0002] A splitting machine is used to split warp-knitted fabric into two single-layer fabrics. Currently, a splitting machine generally consists of a fabric feeding device, a splitting device with a traction structure, and a collection device. In use, the warp-knitted fabric roll is usually assembled onto the fabric feeding device. Then, the traction structure on the splitting device pulls the warp-knitted fabric on the fabric roll, causing the warp-knitted fabric to move on the fabric feeding device. The fabric feeding device then guides the warp-knitted fabric into the splitting device, which then splits the fabric. Finally, the collection device collects the single-layer fabric produced by the splitting process.

[0003] Currently, a feeding device consisting of multiple guide rollers is used to guide the warp-knitted fabric into the slitting machine. However, during the feeding process, factors such as slack can cause the warp-knitted fabric to fail to stretch. A double-roller structure is used for extrusion to unfold the fed warp-knitted fabric, but this method can easily lead to static electricity buildup on the warp-knitted fabric, resulting in a higher probability of defects such as folds and wrinkles, which will affect the feeding effect of the fabric and the subsequent slitting quality. Summary of the Invention

[0013] Furthermore, the auxiliary component includes two auxiliary rollers, both of which are rotatably connected inside the housing and located on the left side of the V-shaped upper plate. Two auxiliary gears are provided on the rear side of the housing and mesh with each other. The rear ends of the shafts of the two auxiliary rollers pass through the housing and are respectively connected to the two auxiliary gears.

A telescopic rod is provided between the U-shaped bracket and the base, and the telescopic rod is located outside the lifting device.

[0015] The beneficial effects of this invention are:

[0016] 1. An auxiliary traction force is applied to the warp-knitted fabric via a first motor, two traction rollers, and two rotating gears. The movement of the warp-knitted fabric is damped by two auxiliary rollers, two auxiliary gears, and a damping gear, thereby straightening the fabric located between the auxiliary rollers and the traction rollers. Simultaneously, a second motor, a first gear, a first synchronous belt, a second gear, two first spiral rods, a third motor, a third gear, a second synchronous belt, a fourth gear, two second bevel gears, and two second spiral rods are used to tilt and unfold the upper and lower ends of the warp-knitted fabric to both sides. This achieves a tilted and flattened treatment of both ends of the taut warp-knitted fabric, allowing it to enter the splitting machine in a flat state. This effectively reduces the probability of defects such as folds and wrinkles on the fabric entering the splitting machine, effectively ensuring the feeding effect and subsequent splitting quality of the fabric.

[0017] 2. The warp-knitted fabric roll is conveniently placed using the mounting frame, placement rollers, and rotating shaft. The rotating shaft, placement rollers, and warp-knitted fabric roll are supported by an electric push rod and a U-shaped bracket, achieving stable assembly of the warp-knitted fabric roll. This effectively reduces the probability of the warp-knitted fabric roll slipping and the probability of the fed warp-knitted fabric folding, thus ensuring the feeding effect.

[0018] 3. By using four U-shaped magnetic strips and two elliptical magnetic strips, the structure formed by two elliptical plates and two tension rollers is suspended in the air, while the two U-shaped limiting covers restrict the structure, thereby expanding the moving warp-knitted fabric. This achieves straightening of the front and rear ends of the warp-knitted fabric to be cut, effectively reducing the probability of slack at the front and rear ends of the warp-knitted fabric to be cut due to the flattening operation, effectively reducing the probability of defects such as sawtooth on the cut surface of the warp-knitted fabric during cutting, and effectively ensuring the feeding effect of the fabric and the subsequent cutting quality.

[0019] 4. The upper and lower layers of the warp-knitted fabric are separated by a separation plate. At the same time, the static electricity generated on the warp-knitted fabric will enter the water in the water box along the separation plate and multiple conductive rods, realizing the separation-type static elimination treatment of the warp-knitted fabric. This effectively reduces the probability of tearing caused by the expansion of the warp-knitted fabric, and effectively ensures the feeding effect of the fabric and the subsequent splitting quality.

[0020] 5. Two second guide rollers limit the upper and lower ends of the horizontal section of multiple conductive rods. At the same time, two first guide rollers and two second guide rollers are used to guide the taut warp-knitted fabric in an orderly manner. This effectively reduces the probability of the warp-knitted fabric accumulating at the inlet and outlet of the U-shaped cavity formed by the U-shaped limiting cover and tension rollers. It also effectively avoids the shaking of the water box, elliptical plate and two tension rollers caused by the shaking of the separating plate during the separation movement. This effectively reduces the probability of the warp-knitted fabric getting stuck and ensures the feeding effect of the fabric and the subsequent splitting quality. Attached Figure Description

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a thin fabric feeding device for a warp-knitted fabric splitting machine is provided, including a base 1, a mounting frame 11 located on the left side of the outer casing 2 is mounted on the upper end of the base 1, the mounting frame 11 provides a mounting carrier for the rotating shaft 13, and the rotating shaft 13, whose front end extends into the U-shaped bracket 14 and is in contact with the bottom end of the U-shaped bracket 14, is rotatably connected to the upper front end of the mounting frame 11, the placing roller 12 is movably connected to the mounting frame 11 through the rotating shaft 13, and the placing roller 12 is mounted on the outer end of the rotating shaft 13, the placing roller 12 provides a mounting carrier for the warp-knitted thin fabric roll;

[0040] The U-shaped bracket 14 located on the left side of the outer casing 2 is attached to the front end of the placement roller 12. The rotating shaft 13 is lifted by the U-shaped bracket 14. The movable part of the lifting device, whose fixed part is located on the upper end of the base 1, is installed on the lower end of the U-shaped bracket 14. The lifting device drives the U-shaped bracket 14 to move up and down. The lifting device can be an electric push rod 15. The telescopic rod 16 located on the outside of the lifting device is placed between the U-shaped bracket 14 and the base 1. The movement of the U-shaped bracket 14 is guided by the telescopic rod 16.

[0041] The two vertical parts of the U-shaped shell 2 are both set on the upper end of the base 1. The shell 2 provides a mounting carrier for components such as auxiliary rollers 9. The two auxiliary rollers 9 located on the left side of the V-shaped upper plate 8 are rotatably connected inside the shell 2. The two auxiliary rollers 9 work together to guide the released warp-knitted fabric. The rear ends of the shafts of the two auxiliary rollers 9 pass through the shell 2 and are respectively connected to two meshing auxiliary gears 22 located on the rear side of the shell 2. The damping gear 23 rotatably connected to the rear end of the shell 2 meshes with the lower end of the auxiliary gear 22 located on the lower side. The damping gear 23 and the two auxiliary gears 22 work together to dampen the two auxiliary rollers 9.

[0042] Two traction rollers 6 located on the right side of the V-shaped upper plate 8 are rotatably connected inside the housing 2. The two traction rollers 6 work together to pull the warp-knitted fabric. The fixed part of the third drive device, whose output shaft is connected to the shaft of one of the traction rollers 6, is set on the front end of the housing 2. The third drive device drives the corresponding traction roller 6 to rotate. The third drive device can be the first motor 3. The rear ends of the shafts of the two traction rollers 6 pass through the housing 2 and are respectively connected to two meshing rotating gears 21 located on the rear side of the housing 2. The two rotating gears 21 work together to make the two traction rollers 6 move relative to each other.

[0043] A V-shaped lower plate 7, which is narrower on the left and wider on the right, is installed inside the outer casing 2. The V-shaped lower plate 7 provides a mounting carrier for components such as the first connecting block 73. Multiple first connecting blocks 73, whose other ends are connected to the inner wall of the outer casing 2, are respectively installed on the front and rear ends of the V-shaped lower plate 7. The multiple first connecting blocks 73 work together to fix the V-shaped lower plate 7 to the outer casing 2. Then, a V-shaped upper plate 8, which is narrower on the left and wider on the right and located directly above the V-shaped lower plate 7, is installed inside the outer casing 2. The V-shaped upper plate 8 provides a mounting carrier for components such as the second connecting block 83. Multiple second connecting blocks 83, whose other ends are connected to the inner wall of the outer casing 2, are respectively installed on the front and rear ends of the V-shaped upper plate 8. The multiple second connecting blocks 83 work together to fix the V-shaped upper plate 8 to the outer casing 2.

[0044] Two first spiral rods 71, arranged in a V-shape with a narrower left side and a wider right side, are rotatably connected to the upper end of the V-shaped lower plate 7 via bearing seats. The two first spiral rods 71 ​​work together to unfold the lower end face of the warp-knitted fabric outward. Two meshing first bevel gears 72 are respectively set on the left ends of the two first spiral rods 71. The two first bevel gears 72 work together to make the two first spiral rods 71 ​​rotate synchronously. A second gear 76 located on the outside of the V-shaped lower plate 7 is installed on the right end of the first spiral rod 71 located on the front side. The corresponding first spiral rod 71 is rotated through the second gear 76. The output shaft of the first drive device, whose fixing part is located at the lower front end of the V-shaped lower plate 7, is connected to the first gear 75 located directly below the second gear 76 and connected to the second gear 76 through a first synchronous belt. The first drive device drives the first gear 75 to rotate. The first drive device can be a second motor 74.

[0045] Two second spiral rods 81, arranged in a V-shape (narrower on the left and wider on the right) and located directly above the two first spiral rods 71, are rotatably connected to the upper end of the V-shaped upper plate 8 via bearing seats. The two second spiral rods 81 work together to unfold the upper surface of the warp-knitted fabric outward. Two meshing second bevel gears 82 are respectively set on the left ends of the two second spiral rods 81. The two second bevel gears 82 work together to make the two second spiral rods 81 rotate synchronously. A fourth gear 86, located on the outside of the V-shaped upper plate 8, is installed on the right end of the second spiral rod 81 located on the front side. The corresponding second spiral rod 81 is rotated through the fourth gear 86. The output shaft of the second drive device, whose fixing part is located at the upper front end of the V-shaped upper plate 8, is connected to a third gear 85 located directly above the fourth gear 86 and connected to the fourth gear 86 via a second synchronous belt. The third gear 85 is driven to rotate through the second drive device, which can be a third motor 84.

[0046] In use, first, the warp-knitted fabric roll is placed on the outer end of the placement roller 12. Then, the electric push rod 15 is activated, which drives the U-shaped bracket 14 to move upward and causes the rotating shaft 13 to enter the U-shaped bracket 14 and contact the bottom of the U-shaped bracket 14. This lifts the rotating shaft 13, the placement roller 12, and the warp-knitted fabric roll, and restricts the installation of the warp-knitted fabric roll, thus achieving stable assembly of the warp-knitted fabric roll. This effectively reduces the probability of the warp-knitted fabric roll slipping and the probability of the fed warp-knitted fabric folding, thus effectively ensuring the feeding effect.

[0047] Then, the movable end of the warp-knitted fabric roll is introduced into the housing 2 from one end of the housing 2 and inserted between the two auxiliary rollers 9, then between the first spiral rod 71 and the second spiral rod 81, then between the two traction rollers 6, and then led out from the other end of the housing 2 and introduced into the main body of the splitting machine and connected to the traction part on the main body of the splitting machine. Then, the warp-knitted fabric roll is pulled, so that the warp-knitted fabric moves inside the housing 2.

[0048] At the same time, the first motor 3 is started, driving the corresponding traction roller 6 to rotate and causing the corresponding rotating gear 21 to rotate. Since the two rotating gears 21 mesh with each other, the rotation of one rotating gear 21 will cause the other rotating gear 21 to rotate, which in turn will cause the other traction roller 6 to rotate and cause the two traction rollers 6 to move relative to each other, thereby applying auxiliary traction force to the warp-knitted fabric, so that the warp-knitted fabric can effectively enter the outer shell 2 from the warp-knitted fabric roll.

[0049] During the feeding process of warp-knitted thin fabric, the two auxiliary rollers 9 will move relative to each other, which in turn will cause the two auxiliary gears 22 to move relative to each other. With the assistance of the damping gear 23, and the two auxiliary gears 22 meshing with each other, the movement of the two auxiliary rollers 9 is damped, thereby damping the movement of the warp-knitted thin fabric, and thus making the warp-knitted thin fabric located between the auxiliary rollers 9 and the traction rollers 6 taut.

[0050] Simultaneously, the second motor 74 and the third motor 84 are started. The operation of the second motor 74 will drive the first gear 75 to rotate, and with the assistance of the first synchronous belt, the second gear 76 will rotate, which in turn will cause the corresponding first spiral rod 71 to rotate, and the corresponding first bevel gear 72 to rotate. Since the two first bevel gears 72 mesh with each other, the rotation of one first bevel gear 72 will cause the other first bevel gear 72 to rotate, which will cause the two first spiral rods 71 ​​to rotate synchronously. The synchronous rotation of the two first spiral rods 71 ​​will cause the lower end of the warp-knitted fabric to be tilted and unfolded to both sides.

[0051] The operation of the third motor 84 will drive the third gear 85 to rotate, and with the assistance of the second synchronous belt, the fourth gear 86 will rotate, which in turn will cause the corresponding second spiral rod 81 to rotate, and the corresponding second bevel gear 82 to rotate. Since the two second bevel gears 82 mesh with each other, the rotation of one second bevel gear 82 will cause the other second bevel gear 82 to rotate, which will cause the two second spiral rods 81 to rotate synchronously. The synchronous rotation of the two first spiral rods 71 ​​will cause the upper end of the warp-knitted fabric to be tilted and unfolded to both sides.

[0052] The method achieves inclined flattening treatment of both ends of the warp-knitted fabric in a taut state, which allows the warp-knitted fabric to enter the slitting machine in a flat state. This effectively reduces the probability of defects such as folds and wrinkles caused by static electricity and other factors on the warp-knitted fabric entering the slitting machine, and effectively ensures the feeding effect of the fabric and the subsequent slitting quality.

[0053] Example 2: Two first spiral rods 71 ​​and two second spiral rods 81 are used to flatten the upper and lower ends of the warp-knitted fabric. However, this flattening method pushes the warp-knitted fabric to the front and rear ends, which increases the probability of loosening at the front and rear ends of the warp-knitted fabric to be cut. This results in a higher probability of defects such as saw teeth appearing on the cut surface of the warp-knitted fabric during subsequent cutting.

[0054] To solve the above problems, such as Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, two U-shaped limiting covers 4 are symmetrically installed inside the outer shell 2. The U-shaped limiting covers 4 limit the tension roller 53 on the one hand, and provide a mounting carrier for components such as the U-shaped magnetic strip 41 on the other hand. Two elliptical plates 5, with their upper and lower ends extending into the two U-shaped limiting covers 4 respectively, are symmetrically arranged between the two U-shaped limiting covers 4. The two elliptical plates 5 work together to provide a mounting carrier for the tension roller 53. Then, the two tension rollers 53, which are located in the two U-shaped limiting covers 4 respectively, are symmetrically rotated and connected between the two elliptical plates 5. The two tension rollers 53 work together to expand the warp-knitted fabric.

[0055] Two elliptical magnetic strips 55 are respectively embedded on the outer ends of two elliptical plates 5. Two U-shaped magnetic strips 41 are symmetrically embedded on the inner walls of the two U-shaped limiting covers 4, located directly outside the elliptical magnetic strips 55 and arranged in a mutually repelling manner with the elliptical magnetic strips 55. The elliptical magnetic strips 55 and the U-shaped magnetic strips 41 are used together to make the elliptical plates 5 stably suspended in the air. A water box 51 located between the two U-shaped limiting covers 4 is installed between the two elliptical plates 5. The water box 51 is used to store water on the one hand and to provide an installation carrier for the conductive rod 52 on the other hand.

[0056] Multiple vertical sections, which are evenly spaced on the upper part of the water box 51, extend into the water box 51 and have an L-shaped cross-section. The left end of the horizontal section of the conductive rod 52, which is located between the two U-shaped limiting covers 4, is connected to the right end of the separation plate 54, which is located to the left of the U-shaped limiting cover 4, to the right of the V-shaped upper plate 8, and has a triangular cross-section. The multiple conductive rods 52 work together to provide a mounting carrier for the separation plate 54 and to guide static electricity into the water in the water box 51.

[0057] In use, the warp-knitted fabric roll is first assembled onto the outer end of the placement roller 12. Then, the movable end of the warp-knitted fabric roll is introduced into the outer shell 2 from one end and sequentially inserted between the two auxiliary rollers 9, between the first spiral rod 71 and the second spiral rod 81, and between the two traction rollers 6. Then, the separating plate 54, the two elliptical plates 5, and the two tension rollers 53 are inserted into the warp-knitted fabric. The repulsive force formed between the four U-shaped magnetic strips 41 and the two elliptical magnetic strips 55 causes the structure formed by the two elliptical plates 5 and the two tension rollers 53 to be suspended. The two U-shaped limiting covers 4 restrict the structure. Then, the warp-knitted fabric is led out from the other end of the outer shell 2 and introduced into the main body of the splitting machine and connected to the traction part on the main body of the splitting machine. Then, the warp-knitted fabric roll is pulled, so that the warp-knitted fabric moves inside the outer shell 2.

[0058] Simultaneously, the first motor 3 and two traction rollers 6 are used to apply auxiliary traction force to the warp-knitted fabric, thereby enabling the warp-knitted fabric to be fed into the outer shell 2. This allows the separating plate 54 to separate the upper and lower layers of the warp-knitted fabric. At the same time, the static electricity generated on the warp-knitted fabric will enter the water in the water box 51 along the separating plate 54 and multiple conductive rods 52, realizing the separation-type static electricity removal treatment of the warp-knitted fabric. This effectively reduces the probability of tearing caused by the expansion of the warp-knitted fabric, effectively ensuring the feeding effect of the fabric and the subsequent splitting quality.

[0059] Then, the upper and lower layers separated from the warp-knitted fabric enter the two U-shaped cavities formed by the two U-shaped limiting covers 4 and the two tension rollers 53, respectively. The suspended structure formed by the two elliptical plates 5 and the two tension rollers 53 moves relative to the warp-knitted fabric, thereby expanding the moving warp-knitted fabric and straightening the front and rear ends of the warp-knitted fabric to be cut. This effectively reduces the probability of slack at the front and rear ends of the warp-knitted fabric to be cut due to the flattening operation, effectively reduces the probability of defects such as saw teeth on the cut surface of the warp-knitted fabric during the cutting process, and effectively ensures the feeding effect of the fabric and the subsequent cutting quality.

[0060] Example 3: Two first spiral rods 71 ​​and two second spiral rods 81 are used to flatten the upper and lower ends of the warp-knitted fabric. The upper and lower layers of the warp-knitted fabric are separated by a separating plate 54. Then, two elliptical plates 5 and two tension rollers 53 are used to straighten the front and rear ends of the flattened warp-knitted fabric at the section to be cut. However, when the upper and lower layers of the warp-knitted fabric move in the two U-shaped cavities formed by the two U-shaped limiting covers 4 and the two tension rollers 53, they are prone to accumulation at the inlet and outlet of the U-shaped cavities. Moreover, the shaking generated by the separating plate 54 during the separation movement can cause the water box 51, the elliptical plate 5, and the two tension rollers 53 to shake, resulting in a high probability of the warp-knitted fabric getting stuck in the U-shaped cavities.

[0061] To solve the above problems, such as Figure 13 , Figure 14 and Figure 15 As shown, two first plates 401 located on the right side of the elliptical plate 5 are symmetrically installed between two U-shaped limiting covers 4. The two first plates 401 work together to provide a mounting carrier for the two first guide rollers 402. Two first guide rollers 402 extending out of the left side of the first plates 401, eccentrically arranged with the first plates 401 and located on the right side of the elliptical plate 5 are symmetrically rotatably connected between the two first plates 401. The two first guide rollers 402 work together to guide the warp-knitted fabric out from inside the U-shaped limiting cover 4.

[0062] Two second plates 404 located on the left side of the elliptical plate 5 and outside the conductive rod 52 are symmetrically installed between the two U-shaped limiting covers 4. The two second plates 404 work together to provide a mounting carrier for the two second guide rollers 403. Two second guide rollers 403 located on the upper and lower sides of the conductive rod 52, extending out of the right side of the second plates 404 and eccentrically arranged with the first plate 401, and located on the left side of the elliptical plate 5, are symmetrically rotated and connected between the two second plates 404. The two second guide rollers 403 work together to guide the warp-knitted thin fabric into the U-shaped limiting cover 4.

[0063] In use, first, the warp-knitted fabric roll is assembled onto the outer end of the placement roller 12. Then, the movable end of the warp-knitted fabric roll is introduced into the outer shell 2 from one end of the outer shell 2 and inserted between the two auxiliary rollers 9, between the first spiral rod 71 and the second spiral rod 81, and between the two traction rollers 6 in sequence. Then, the separation plate 54, the two elliptical plates 5, and the two tension rollers 53 are inserted into the warp-knitted fabric, while the two first guide rollers 402 and the two second guide rollers 403 are respectively attached to the upper and lower ends of the warp-knitted fabric.

[0064] The two second guide rollers 403 and the upper and lower layers of warp-knitted fabric limit the upper and lower ends of the horizontal part of the multiple conductive rods 52. At the same time, the two second guide rollers 403 introduce the upper and lower layers of warp-knitted fabric into the two U-shaped cavities formed by the two U-shaped limiting covers 4 and the two tension rollers 53 respectively, and the two first guide rollers 402 lead the upper and lower layers of warp-knitted fabric in the two U-shaped cavities outward.

[0065] This method enables orderly guidance of the taut warp-knitted fabric, effectively reducing the probability of the fabric piling up at the inlet and outlet of the U-shaped cavity formed by the U-shaped limiting cover 4 and the tension roller 53. It also effectively prevents the water box 51, the elliptical plate 5, and the two tension rollers 53 from shaking due to the shaking of the separating plate 54 during the separation movement, thus effectively reducing the probability of the warp-knitted fabric getting stuck and ensuring the feeding effect and subsequent splitting quality of the fabric.

[0066] Then, the first motor 3 and two traction rollers 6 are used to apply auxiliary traction force to the warp-knitted fabric, so that the warp-knitted fabric can be fed into the outer shell 2. The upper and lower layers of the warp-knitted fabric are separated by the separation plate 54. At the same time, the separation plate 54, multiple conductive rods 52 and water in the water box 51 are used to perform separation-type static elimination treatment on the warp-knitted fabric. Then, the moving warp-knitted fabric is expanded by the suspended structure formed by two elliptical plates 5 and two tension rollers 53. Then, the expanded and flat warp-knitted fabric is pulled into the splitting machine, and then the warp-knitted fabric is split.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
