At present, the slitting machine is generally composed of a thin fabric feeding device, a slitting device with a traction structure, and a collecting device. When in use, the warp knitted thin fabric roll is generally assembled on the thin fabric feeding device, and then the warp knitted thin fabric on the warp knitted thin fabric roll is pulled by the traction structure on the slitting device, so that the warp knitted thin fabric moves on the thin fabric feeding device, and then the thin fabric feeding device is used to guide the warp knitted thin fabric into the slitting device, and then the slitting device is used to slitting the warp knitted thin fabric, and then the single-layer fabric produced by slitting is collected by the collecting device; At present, a feeding device formed by multiple guide wheels is used to guide the warp knitted thin cloth into the slitting machine.

The two first spiral rods 71 ​​are used in conjunction with each other to carry out an outward expansion operation on the lower end surface of the warp-knitted thin cloth, and the two first bevel gears 72 meshing with each other are respectively arranged on the left ends of the two first spiral rods 71. The two first bevel gears 72 are used in conjunction with each other to make the two first spiral rods 71 ​​rotate synchronously, and then the second gear 76 located on the outer side of the V-shaped lower plate 7 is installed on the right end of the first spiral rod 71 located on the front side, and the corresponding first spiral rod 71 is rotated through the second gear 76, and the output shaft of the first driving device with a fixed portion set at the lower end of the front part 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 the first synchronous belt, and the first gear 75 is driven to rotate through the first driving device, and the first driving device can adopt a second motor 74; The two second screw rods 81, which are respectively located above the two first screw rods 71 ​​and are arranged in a V-shaped structure with a narrow left and a wide right, are rotatably connected to the upper end of the V-shaped upper plate 8 through bearing seats. The two second screw rods 81 are used in combination to carry out an outward expansion operation on the upper end surface of the warp-knitted thin cloth, and the two second bevel gears 82 that mesh with each other are respectively set on the left ends of the two second screw rods 81. The two second bevel gears 82 are used in combination to make the two second screw rods 81 rotate synchronously, and then the fourth gear 86 located on the outside of the V-shaped upper plate 8 is installed on the right end of the second screw rod 81 located on the front side. The corresponding second screw rod 81 is rotated through the fourth gear 86, and the output shaft of the second driving device with a fixed portion set at the upper front end of the V-shaped upper plate 8 is connected to the third gear 85 located above the fourth gear 86 and connected to the fourth gear 86 through a second synchronous belt. The third gear 85 is driven to rotate through the second driving device, and the second driving device can use a third motor 84.

[0020] When in use, first put the warp knitted thin fabric roll onto the outer end of the placement roller 12, then start the electric push rod 15, thereby driving the U-shaped bracket 14 to move upward, and making the rotating shaft 13 enter the U-shaped bracket 14 and contact the bottom end of the U-shaped bracket 14, so as to lift the rotating shaft 13, the placement roller 12 and the warp knitted thin fabric roll, and restrict the installation of the warp knitted thin fabric roll, so as to achieve stable assembly of the warp knitted thin fabric roll, effectively reduce the probability of the warp knitted thin fabric roll slipping, effectively reduce the probability of the fed warp knitted thin fabric folding, and effectively ensure the feeding effect; Then, the movable end of the warp knitted thin fabric on the warp knitted thin 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, and then inserted between the first spiral rod 71 and the second spiral rod 81, and then inserted between the two traction rollers 6, and then led out from the other end of the outer shell 2, and introduced into the slitting machine body and connected with the traction part on the slitting machine body, and then the warp knitted thin fabric on the warp knitted thin fabric roll is pulled, so that the warp knitted thin fabric moves in the outer shell 2; At the same time, the first motor 3 is started to drive the corresponding traction roller 6 to rotate, and the corresponding rotating gear 21 is rotated. Since the two rotating gears 21 are meshed with each other, the rotation of one rotating gear 21 will cause the other rotating gear 21 to rotate, thereby rotating the other traction roller 6, and causing the two traction rollers 6 to move relative to each other, thereby applying auxiliary traction force to the warp knitted thin fabric, thereby effectively allowing the warp knitted thin fabric to enter the housing 2 from the warp knitted thin fabric roll; During the feeding process of the warp knitted thin fabric, the two auxiliary rollers 9 will move relative to each other, and then the two auxiliary gears 22 will move relative to each other, and with the assistance of the damping gear 23, the two auxiliary gears 22 will mesh with each other, so the movement of the two auxiliary rollers 9 will be damped, thereby damping the movement of the warp knitted thin fabric, and then the warp knitted thin fabric between the auxiliary rollers 9 and the traction roller 6 will be in a straightened state; The second motor 74 and the third motor 84 are started at the same time. The second motor 74 drives the first gear 75 to rotate, and with the assistance of the first synchronous belt, the second gear 76 is rotated, thereby rotating the corresponding first spiral rod 71 and the corresponding first bevel gear 72. Since the two first bevel gears 72 are meshed with each other, the rotation of one first bevel gear 72 will cause the other first bevel gear 72 to rotate, thereby causing the two first spiral rods 71 ​​to rotate synchronously. The synchronous rotation of the two first spiral rods 71 ​​will cause the lower end surface of the warp-knitted thin cloth to be inclined to both sides. The third motor 84 drives the third gear 85 to rotate, and with the assistance of the second synchronous belt, the fourth gear 86 rotates, thereby rotating the corresponding second spiral rod 81 and the corresponding second bevel gear 82. Since the two second bevel gears 82 are meshed with each other, the rotation of one second bevel gear 82 causes the other second bevel gear 82 to rotate, thereby causing the two second spiral rods 81 to rotate synchronously. The synchronous rotation of the two first spiral rods 71 ​​will tilt the upper end surface of the warp-knitted thin cloth toward both sides. The upper and lower ends of the warp knitted thin fabric in a stretched state are both inclined and flattened, so that the warp knitted thin fabric can enter the slitting machine in a flat state, effectively reducing the probability of defects such as folds and wrinkles on the warp knitted thin fabric entering the slitting machine due to factors such as static electricity, and effectively ensuring the feeding effect of the thin fabric and the subsequent slitting quality.

[0021] Embodiment 2: Two first spiral rods 71 ​​and two second spiral rods 81 are used to smooth the upper and lower end surfaces of the warp knitted thin cloth. However, this smoothing method will push the warp knitted thin cloth toward the front and rear ends, resulting in a high probability that the positions to be cut at the front and rear ends of the warp knitted thin cloth will become loose, resulting in a high probability of defects such as sawtooth on the cut surface of the warp knitted thin cloth during subsequent cutting.

[0022] In order to solve the above problems, Figure 3 , Figure 4 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, two relatively arranged U-shaped limiting covers 4 are symmetrically installed inside the housing 2. The U-shaped limiting covers 4 are used to limit the tensioning roller 53 on the one hand, and to provide a mounting carrier for the U-shaped magnetic strip 41 and other components on the other hand. The two elliptical plates 5 extending into the two U-shaped limiting covers 4 at their upper and lower ends are symmetrically arranged between the two U-shaped limiting covers 4. The two elliptical plates 5 are used in combination to provide a mounting carrier for the tensioning roller 53. The two tensioning rollers 53 respectively located in the two U-shaped limiting covers 4 are symmetrically rotated and connected between the two elliptical plates 5. The two tensioning rollers 53 are used in combination to expand the warp knitted thin cloth. Two elliptical magnetic strips 55 are respectively embedded on the outer ends of the two elliptical plates 5, and two U-shaped magnetic strips 41 are symmetrically embedded on the inner walls of the two U-shaped limiting covers 4, which are located just outside the elliptical magnetic strips 55 and are arranged to repel each other. The elliptical magnetic strips 55 and the U-shaped magnetic strips 41 are used in conjunction with each other to ensure that the elliptical plates 5 are stably suspended and installed. 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 a mounting carrier for the conductive rod 52 on the other hand. The left end of the transverse portion of a conductive rod 52, which has multiple vertical portions equidistantly installed on the upper end of the water box 51 and extends into the water box 51 and has an L-shaped cross-section and is located between two U-shaped limit covers 4, is connected to the right end of a separation plate 54, which is located on the left side of the U-shaped limit cover 4 and on the right side of the V-shaped upper plate 8 and has a triangular cross-section. The multiple conductive rods 52 are used in combination to, on the one hand, provide a mounting carrier for the separation plate 54 and, on the other hand, guide static electricity into the water in the water box 51.

[0023] When in use, first assemble the warp knitted thin cloth roll onto the outer end of the placement roller 12, then introduce the movable end of the warp knitted thin cloth on the warp knitted thin cloth roll into the shell 2 from one end of the shell 2, and insert it in sequence 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 insert the separation plate 54, the two elliptical plates 5, the two tensioning rollers 53 and other components into the warp knitted thin cloth, and the repulsive force formed between the four U-shaped magnetic strips 41 and the two elliptical magnetic strips 55, thereby making the structure formed by the two elliptical plates 5 and the two tensioning rollers 53 in a suspended state, and the two U-shaped limit covers 4 will restrict the structure, and then lead the warp knitted thin cloth out from the other end of the shell 2, and introduce it into the main body of the slitting machine and connect it to the traction part on the main body of the slitting machine, and then pull the warp knitted thin cloth on the warp knitted thin cloth roll, so that the warp knitted thin cloth moves in the shell 2; At the same time, the first motor 3 and the two traction rollers 6 are used to apply auxiliary traction force to the warp knitted thin fabric, so that the warp knitted thin fabric is fed into the outer shell 2, so that the separation plate 54 separates the upper and lower layers of the warp knitted thin fabric. At the same time, the static electricity generated on the warp knitted thin fabric will enter the water in the water box 51 along the separation plate 54 and the multiple conductive rods 52, so as to achieve separate static electricity removal for the warp knitted thin fabric, effectively reduce the probability of tearing caused by the expansion of the warp knitted thin fabric, and effectively ensure the feeding effect of the thin fabric and the quality of subsequent slitting; Then the upper and lower layers separated from the warp knitted thin cloth respectively enter the two U-shaped cavities formed by the two U-shaped limit covers 4 and the two tensioning rollers 53, and the suspended structure formed by the two elliptical plates 5 and the two tensioning rollers 53 moves relative to the warp knitted thin cloth, thereby expanding the moving warp knitted thin cloth, and straightening the front and rear ends of the warp knitted thin cloth to be cut, effectively reducing the probability of loosening of the front and rear ends of the warp knitted thin cloth to be cut due to leveling operations, and effectively reducing the probability of defects such as sawtooth on the cut surface of the warp knitted thin cloth during cutting, effectively ensuring the feeding effect of the thin cloth and the subsequent cutting quality.

[0024] Embodiment 3: Two first spiral rods 71 ​​and two second spiral rods 81 are used to smooth the upper and lower end surfaces of the warp knitted thin cloth, and the upper and lower layers of the warp knitted thin cloth are separated by a separation plate 54, and then two elliptical plates 5 and two tensioning rollers 53 are used to straighten the front and rear ends of the smoothed warp knitted thin cloth to be cut. However, when the upper and lower layers of the warp knitted thin cloth move in two U-shaped cavities formed by two U-shaped limit covers 4 and two tensioning rollers 53 respectively, accumulation and the like are easily generated at the inlet and outlet positions of the U-shaped cavity, and the shaking of the separation plate 54 during the separation movement is likely to cause the water box 51, the elliptical plate 5 and the two tensioning rollers 53 to shake, resulting in a high probability of the warp knitted thin cloth getting stuck in the U-shaped cavity.

[0025] In order to solve the above problems, Fig.13 , Fig.14 and Fig.15 As shown, two first plates 401 located on the right side of the elliptical plate 5 are symmetrically installed between the two U-shaped limiting covers 4. The two first plates 401 are used in conjunction with each other to provide a mounting carrier for the two first guide rollers 402. Two first guide rollers 402 extending from the left side of the first plates 401 and eccentrically arranged with the first plates 401 and located on the right side of the elliptical plate 5 are symmetrically rotated and connected between the two first plates 401. The two first guide rollers 402 are used in conjunction with each other to guide the warp knitted thin fabric out of the U-shaped limiting cover 4. Two second plates 404 located on the left side of the elliptical plate 5 and on the outside of the conductive rod 52 are symmetrically installed between the two U-shaped limit covers 4. The two second plates 404 are used in combination 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 from the right side of the second plate 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 are used in combination to guide the warp-knitted thin cloth into the U-shaped limit cover 4.

[0026] When in use, first assemble the warp knitted thin fabric roll onto the outer end of the placement roller 12, then introduce the movable end of the warp knitted thin fabric on the warp knitted thin fabric roll into the outer shell 2 from one end of the outer shell 2, and insert it 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 insert the separation plate 54, the two elliptical plates 5, the two tensioning rollers 53 and other components into the warp knitted thin fabric, and 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 thin fabric; The two second guide rollers 403 and the upper and lower layers of the warp knitted thin fabric will limit the upper and lower ends of the transverse parts of the multiple conductive rods 52. At the same time, the upper and lower layers of the warp knitted thin fabric will be introduced into the two U-shaped cavities formed by the two U-shaped limiting covers 4 and the two tensioning rollers 53 through the two second guide rollers 403, and the upper and lower layers of the warp knitted thin fabric in the two U-shaped cavities will be led outward by the two first guide rollers 402. The straightened warp knitted thin fabric is guided in an orderly manner, and the probability of the warp knitted thin fabric being piled up at the inlet and outlet of the U-shaped cavity formed by the U-shaped limiting cover 4 and the tensioning roller 53 is effectively reduced, and the shaking of the water box 51, the elliptical plate 5 and the two tensioning rollers 53 caused by the shaking of the separation plate 54 during the separation movement is effectively avoided, and the probability of the warp knitted thin fabric being stuck is effectively reduced, and the feeding effect of the thin fabric and the quality of the subsequent slitting are effectively guaranteed; Then, the first motor 3 and the two traction rollers 6 are used to apply auxiliary traction force to the warp knitted thin cloth, so that the warp knitted thin cloth is fed in the outer shell 2, and the upper and lower layers of the warp knitted thin cloth are separated by the separation plate 54. At the same time, the separation plate 54, multiple conductive rods 52 and the water in the water box 51 are used to perform a separate static electricity removal treatment on the warp knitted thin cloth, and then the moving warp knitted thin cloth is expanded by a suspended structure formed by two elliptical plates 5 and two tensioning rollers 53, and then the expanded and flat warp knitted thin cloth is pulled into the slitting machine, and then the warp knitted thin cloth is slit.
