Description

Technical Field

[0001] The present application relates to the technical field of metal processing equipment, and particularly to a device for adjusting the tension of metal sheets. Background Art

[0002] During the production and processing of steel coils, it is usually necessary to uncoil the steel coil first, and then perform operations such as cutting, edge trimming, and cleaning on the uncoiled steel plate. Finally, the processed steel plate is coiled up. In the process of coiling the steel plate, an appropriate tension needs to be provided to ensure the tightness of the finished steel coil.

[0003] In the prior art, a pair of rollers are usually used to clamp the upper and lower surfaces of the steel plate to provide the coiling tension. However, when dealing with steel plates of different thicknesses, this tension adjustment device has obvious deficiencies. For thin plates, due to their thin thickness and easy deformation, clamping with rollers is likely to cause the steel plate to deform and bend, affecting the coiling quality. For thick plates, due to their large thickness, a greater tension is required to ensure tightness during coiling, but the clamping force provided by the roller clamping is difficult to meet the requirements. Therefore, the existing tension adjustment devices are difficult to be applicable to the coiling of both thick and thin plates at the same time, and cannot effectively solve the different tension requirements of plates with different thicknesses during the coiling process.

[0004] In summary, there is an urgent need for a tension adjustment device that can be applicable to both thick and thin plates at the same time to solve the problems existing in the prior art. Summary of the Invention

[0005] In order to improve the applicability of the tension adjustment device and the quality and tightness of the steel plate coiling, the present application provides a device for adjusting the tension of metal sheets.

[0006] The device for adjusting the tension of metal sheets provided by the present application adopts the following technical solutions: A device for adjusting the tension of metal sheets, comprising: A frame, which is arranged at the steel plate input end of the coiling machine; A clamping assembly, which is arranged on the frame. The clamping assembly includes a first clamping plate, a second clamping plate, and a first telescopic driving member. The first clamping plate and the second clamping plate are oppositely arranged on the frame and respectively slide and abut against the upper and lower surfaces of the steel plate. The first telescopic driving member is used to drive at least one of the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate generate relative displacement towards or away from each other; The rolling component is arranged on the frame. The rolling component includes a plurality of first pressing rollers, a plurality of second pressing rollers and a second telescopic driving member; the plurality of first pressing rollers and second pressing rollers are staggered on the frame and can rotate, and the first pressing rollers and the second pressing rollers respectively roll and abut against the upper and lower surfaces of the steel plate; the second telescopic driving member is used to drive at least one of the first pressing rollers and the second pressing rollers, so that the first pressing rollers and the second pressing rollers generate relative displacements towards or away from each other.

[0007] By adopting the above technical solution, when winding a thin steel plate, since the required winding force is small, only the frictional forces between the first clamping plate and the second clamping plate and the upper and lower surfaces of the steel plate can provide appropriate tension for the steel plate. At the same time, the first clamping plate and the second clamping plate can also slightly flatten the steel plate, effectively reducing the deformation problems that may occur during the winding process of the steel plate. When winding a thick steel plate, because a greater winding force is required, at this time the rolling component comes into play, and a plurality of first pressing rollers and second pressing rollers press the steel plate into a state similar to a "wavy" shape. This design makes the steel plate have to overcome its own deformation resistance during winding, thereby significantly increasing the tension applied to the steel plate and ensuring that the thick steel plate can also be tightly wound.

[0008] Optionally, it further includes a conveying component. The conveying component includes a first conveying roller, a second conveying roller and a third telescopic driving member; the first conveying roller and the second conveying roller are oppositely arranged on the frame, and the first conveying roller and / or the second conveying roller can rotate actively, and the first conveying roller and the second conveying roller respectively roll and abut against the upper and lower surfaces of the steel plate; the third telescopic driving member is used to drive at least one of the first conveying roller and the second conveying roller, so that the first conveying roller and the second conveying roller generate relative displacements towards or away from each other.

[0009] By adopting the above technical solution, the arrangement of the conveying component can realize the active conveying of the steel plate. The first conveying roller and the second conveying roller respectively roll and abut against the upper and lower surfaces of the steel plate, and at least one of them can rotate actively, thereby providing stable forward power for the steel plate. The third telescopic driving member drives the first conveying roller and the second conveying roller to generate relative displacements towards or away from each other, so that the conveying component can adapt to steel plates of different thicknesses and improve the applicability of the device.

[0010] Optionally, it further includes a guiding component. The guiding component includes a guiding roller, a guiding plate and a fourth telescopic driving member. The guiding roller is rotatably arranged at one end of the frame close to the winder; the guiding plate is rotatably arranged on the frame and is located on the side of the guiding roller close to the winder, and the top surface of the guiding plate is used to receive the steel plate; the fourth telescopic driving member is used to drive the guiding plate to be close to or away from the winder.

[0011] By adopting the above technical solution, the setting of the guide roller can make a preliminary correction to the forward direction of the steel plate, effectively preventing the steel plate from being offset or bending at a large angle to produce creases when entering the winder. The guide plate can provide stable support for the end of the steel plate when it first enters the winder, preventing the end of the steel plate from sagging or deforming due to loss of support. In addition, the fourth telescopic drive member can drive the guide plate closer to or away from the winder according to actual needs. When the guide plate is needed, it can be moved to a position close to the winder to provide support and guidance; when it is not needed, the guide plate can be withdrawn to avoid interference with other operations. This flexible adjustment method significantly improves the adaptability and ease of operation of the device.

[0012] Optionally, it also includes a limit assembly and a cutting machine, wherein the limit assembly is used to limit the lateral deviation of the steel plate when it is rolled up; and the cutting machine is arranged on a frame and is used to cut the steel plate.

[0013] By adopting the above technical scheme, the limit assembly can effectively limit the lateral deviation of the steel plate during the rolling process, thereby improving the stability of the steel plate rolling and avoiding the problem of staggered layers caused by deviation; the setting of the cutting machine can accurately cut the steel plate into sections during the steel plate rolling process to ensure that the length of the steel plate meets the production requirements, thereby improving the degree of automation of the entire device.

[0014] Optionally, the limiting assembly includes a first limiting roller and at least two limiting rings; the first limiting roller is rotatably set on the frame and rolls against the steel plate; the two limiting rings are slidably set on the first limiting roller and are respectively located on both sides of the steel plate, and the sides of the two limiting rings that are close to each other slide against the two side edges of the steel plate respectively; the limiting ring can be fixed to the first limiting roller by fastening screws.

[0015] By adopting the above technical solution, the limit ring can flexibly adjust its position according to the width of the steel plate, and is fixed to the first limit roller by fastening screws, thereby realizing effective limit for steel plates of different widths. This design not only avoids lateral displacement of the steel plate during the coiling process, but also ensures that the coiled steel coil has neat edges, thereby improving the overall quality of the finished steel coil. In addition, the sliding cooperation between the limit ring and the first limit roller simplifies the adjustment operation process and improves the adaptability and work efficiency of the equipment.

[0016] Optionally, the limiting assembly also includes a connecting rod, an abutment roller and a fifth telescopic driving member, one end of the connecting rod is rotatably connected to the frame; the abutment roller is arranged opposite to the first limiting roller, and the abutment roller is rotatably arranged at the end of the connecting rod away from the frame, and the abutment roller rolls and abuts against a side of the steel plate away from the first limiting roller; the fifth telescopic driving member is arranged on the frame to drive the end of the connecting rod away from the frame to approach or move away from the steel plate.

[0017] By adopting the above technical solution, the abutting roller and the first limiting roller cooperate with each other to firmly clamp the steel plate between the two, effectively preventing the steel plate from breaking away from the restrictions of the first limiting roller and the limiting ring during the winding process. At the same time, the fifth telescopic driving member drives the connecting rod to act, so that the distance between the abutting roller and the first limiting roller can be adjusted, and the position of the abutting roller can be flexibly adjusted according to steel plates of different thicknesses. In addition, it can also provide a certain tension for the steel plate to prevent the steel plate from loosening.

[0018] Optionally, the limiting assembly includes at least four second limiting rollers, a sixth telescopic driving member, a limiting block and an elastic member; the four second limiting rollers are respectively arranged on the frame in an interlaced manner; and two of the four second limiting rollers roll against the upper surface of the steel plate, and the other two second limiting rollers roll against the lower surface of the steel plate; the sixth telescopic driving member is used to drive the second limiting roller on one side of the upper surface of the steel plate and the second limiting roller on one side of the lower surface of the steel plate to approach or move away from each other. A plurality of relief grooves are equally spaced along the axial direction and the circumferential direction on the rolling surface of the second limiting roller, the limiting block is slidably arranged in the relief groove, and the elastic member is used to make the limiting block pop out of the opening of the relief groove and roll against the steel plate.

[0019] By adopting the above technical solution, the limiting assembly can automatically adjust the limiting width of the steel plate according to the width of the steel plate. Specifically, when the steel plate passes through the second limiting roller, the limiting blocks within the width range of the steel plate are pressed by the steel plate and retracted into the relief grooves, avoiding hindering the normal passage of the steel plate. At the same time, the limiting blocks outside the width range of the steel plate pop out of the relief grooves under the action of the elastic member, and the limiting blocks closest to the two sides of the steel plate can closely fit the two sides of the steel plate, thereby effectively restricting the offset of the steel plate in the width direction, ensuring the stable position of the steel plate during the winding process, and improving the quality and tightness of the winding. This self-adaptive limiting method does not require manual adjustment, is applicable to steel plates of different widths, and significantly improves the applicability and operation convenience of the device.

[0020] Optionally, the relief grooves on the two second limiting rollers on the same side of the steel plate are arranged in a staggered manner along the axial direction of the second limiting roller; the distance between the adjacent inner side walls of the adjacent relief grooves is smaller than the dimensions in the length direction and the width direction of the relief groove itself.

[0021] By adopting the above technical solution, the lateral limiting accuracy of the steel plate by the limiting component can be significantly improved. Specifically, since there is a small gap between adjacent limiting blocks in the axial direction of the second limiting roller, this gap may cause the steel plate to still have a small lateral displacement after being limited. By arranging the relief grooves on two second limiting rollers on the same side in a staggered manner and reducing the distance between the adjacent inner side walls of adjacent relief grooves, the limiting blocks on one second limiting roller can cross-fill the gaps between adjacent limiting blocks on the other second limiting roller. In this way, the limiting areas formed when the limiting blocks contact the steel plate are more dense and continuous, effectively reducing the gaps between the limiting areas. Therefore, this design significantly reduces the lateral displacement range of the steel plate after being limited, greatly reducing the lateral movement space of the steel plate during the coiling process, thereby improving the stability and accuracy of the steel plate coiling.

[0022] Optionally, an airtight air cavity is formed between the side of the limiting block close to the bottom of the relief groove and the relief groove; an air jet hole is provided on the limiting block, one end of the air jet hole communicates with the air cavity, and the other end opens and extends to the side where the limiting block rolls and abuts against the steel plate.

[0023] By adopting the above technical solution, the dust and impurities on the surface of the steel plate can be effectively removed. Specifically, when the steel plate abuts against and presses down the limiting block, the limiting block displaces deeper into the relief hole, thereby compressing the air cavity. As the volume of the air cavity decreases, the internal air pressure increases, and the gas in the air cavity sprays out at high speed from the air jet hole, forming an air flow that directly acts on the surface of the steel plate. This air flow can effectively blow the dust and impurities on the surface of the steel plate, ensuring that the steel plate remains clean during the coiling process, thereby improving the quality of the finished steel coil.

[0024] Optionally, a first one-way valve is provided in the air jet hole, and the first one-way valve is used to prevent external gas from entering the air cavity through the air jet hole; a communication channel is provided on the second limiting roller, one end of the communication channel communicates with the air cavity, and the other end opens and extends to the end face of the second limiting roller to communicate with the outside; a second one-way valve is provided in the communication channel, and the second one-way valve is used to prevent the gas inside the air cavity from discharging to the outside through the communication channel.

[0025] By adopting the above technical solution, when the limiting block compresses the air cavity, the gas in the air cavity can only be discharged from the air jet hole, forming a high-speed air flow to effectively blow the surface of the steel plate and remove dust and impurities; when the limiting block rebounds and resets, the volume of the air cavity expands to generate negative pressure. At this time, external gas can only enter the air cavity through the communication channel, avoiding the problem that dust and impurities near the steel plate are carried back into the air cavity due to gas entering through the air jet hole, thereby ensuring the cleanliness of the gas in the air cavity.

[0026] In summary, the present application includes the following beneficial technical effects: 1. When rolling up thin steel plates, since the required rolling force is relatively small, only the friction between the first and second clamps and the upper and lower surfaces of the steel plates can provide appropriate tension for the steel plates. At the same time, the first and second clamps can also slightly flatten the steel plates, effectively reducing the deformation problems that may occur in the rolling process. When rolling up thick steel plates, since a greater rolling force is required, the rolling assembly comes into play, and multiple first and second rollers press the steel plates into a "wave-like" state. This design requires the steel plates to overcome their own deformation resistance when rolling up, thereby significantly increasing the tension applied to the steel plates and ensuring that thick steel plates can also be rolled up tightly; 2. The limiting assembly can automatically adjust the limiting width of the steel plate according to the width of the steel plate. Specifically, when the steel plate passes through the second limiting roller, the limiting blocks within the width range of the steel plate are returned to the clearance groove due to the pressure of the steel plate, so as to avoid obstruction to the normal passage of the steel plate. At the same time, the limiting blocks outside the width range of the steel plate pop out of the clearance groove under the action of the elastic member, and the limiting blocks closest to the two side edges of the steel plate can fit tightly against the two side edges of the steel plate, thereby effectively limiting the displacement of the steel plate in the width direction, ensuring that the steel plate maintains a stable position during the winding process, and improving the quality and tightness of the winding. This adaptive limiting method does not require manual adjustment and is suitable for steel plates of different widths, which significantly improves the applicability and ease of operation of the device; 3. It can significantly improve the lateral limiting accuracy of the steel plate by the limiting assembly. Specifically, since there is a small gap between adjacent limiting blocks in the axial direction of the second limiting roller, this gap may cause the steel plate to still have a small lateral displacement after being limited. By staggering the clearance grooves on the two second limiting rollers on the same side and reducing the spacing between the adjacent inner walls of the adjacent clearance grooves, the limiting blocks on one second limiting roller can cross-fill the gap between the adjacent limiting blocks on the other second limiting roller. In this way, the limiting area formed when the limiting blocks contact the steel plate is more dense and continuous, effectively reducing the gap between the limiting areas. Therefore, this design significantly reduces the lateral displacement range of the steel plate after limiting, greatly reduces the lateral movement space of the steel plate during the winding process, and thus improves the stability and accuracy of the steel plate during winding.

Detailed description of the specific implementation

[0033] The following is combined with Figures 1-5 to further elaborate on the present application.

The shape of the first clamping plate 21 is rectangular, and its surface can be polished to reduce friction; the first clamping plate 21 is fixedly installed on the frame 1 by bolts. The second clamping plate 22 can also be made of cast iron, and its shape matches that of the first clamping plate 21. The second clamping plate 22 is slidably installed on the frame 1 through a slide rail, and the slide rail can specifically adopt a linear guide rail or a ball guide rail to ensure the smoothness and accuracy of sliding; the second clamping plate 22 is located above the first clamping plate 21 and faces and is parallel to the first clamping plate 21. The steel plate 100 passes through between the first clamping plate 21 and the second clamping plate 22, and the second clamping plate 22 and the first clamping plate 21 respectively slide and abut against the upper and lower surfaces of the steel plate 100.

In this way, when winding the steel plate 100, the first telescopic driving member 23 drives the second clamping plate 22 to cooperate with the first clamping plate 21 to clamp the upper and lower surfaces of the steel plate 100, and the frictional force generated by the first clamping plate 21 and the second clamping plate 22 on the steel plate 100 can provide tension for the steel plate 100. In other embodiments, the first clamping plate 21 and the second clamping plate 22 can also be made of stainless steel or aluminum alloy; a linen cloth can also be laid on the surface of the first clamping plate 21 for abutting against the steel plate 100 to reduce the friction with the steel plate 100.

[0037] Referring to Figure 1 , in this embodiment, the rolling component 3 is arranged on the frame 1 and on the side of the clamping component 2 close to the winder; the rolling component 3 includes two first pressure rollers 31, two second pressure rollers 32 and a second telescopic driving member 33; the two first pressure rollers 31 are fixedly installed on the frame 1 through bearings and can rotate freely around their own axes; the rotation axes of the two first pressure rollers 31 are located in the same horizontal plane and are both parallel to the horizontal plane and perpendicular to the conveying direction when the steel plate 100 is wound. The two second pressure rollers 32 are slidably installed on the frame 1 through slide rails and can rotate freely around their own axes. The slide rails can specifically adopt linear guide rails or ball guide rails to ensure the smoothness and accuracy of sliding; the two second pressure rollers 32 are relatively staggered with the two first pressure rollers 31 and the second pressure rollers 32 are located above the first pressure rollers 31; the rotation axes of the two second pressure rollers 32 are located in the same horizontal plane and are both parallel to the rotation axes of the first pressure rollers 31. The steel plate 100 passes through between the first pressure rollers 31 and the second pressure rollers 32, and the second pressure rollers 32 and the first pressure rollers 31 respectively roll and abut against the upper and lower surfaces of the steel plate 100.

[0038] The second telescopic driving member 33 can be one of a cylinder or a hydraulic cylinder; the second telescopic driving member 33 is fixed on the frame 1, and its output end is connected to the second pressure roller 32 to drive the second pressure roller 32 to generate relative displacement towards or away from the first pressure roller 31, so as to realize the rolling pressure and release of the steel plate 100. In this way, when winding the steel plate 100, the second telescopic driving member 33 drives the second pressure roller 32 to cooperate with the first pressure roller 31 to press the steel plate 100 into a state similar to a "wavy shape", so that the steel plate 100 must overcome its own deformation resistance when being wound, thereby realizing providing tension for the steel plate 100.

[0039] Referring to Figure 1, in this embodiment, the conveying assembly 4 is arranged between the clamping assembly 2 and the rolling assembly 3; the conveying assembly 4 includes a first conveying roller 41, a second conveying roller 42 and a third telescopic driving member 43; motors for driving their own rotation are provided inside both the first conveying roller 41 and the second conveying roller 42, and the motors can be servo motors or stepper motors to achieve precise rotational speed control. The rotational axes of both the first conveying roller 41 and the second conveying roller 42 are parallel to the rotational axis of the second pressing roller 32. The first conveying roller 41 is fixedly installed on the frame 1. The second conveying roller 42 is slidably installed on the frame 1 through a slide rail, and the slide rail can specifically adopt a linear guide rail or a ball guide rail to ensure the smoothness and accuracy of sliding; the second conveying roller 42 is arranged opposite to the first conveying roller 41, and the second conveying roller 42 is located above the first conveying roller 41. The steel plate 100 passes through between the second conveying roller 42 and the first conveying roller 41, and the second pressing roller 32 and the first conveying roller 41 respectively roll and abut against the upper and lower surfaces of the steel plate 100. Rubber sleeves are sleeved on both the first conveying roller 41 and the second conveying roller 42 to increase the friction force when abutting against the steel plate 100.

[0040] The third telescopic driving member 43 can adopt one of a cylinder or a hydraulic cylinder; the third telescopic driving member 43 is fixed on the frame 1, and its output end is connected to the second conveying roller 42 to drive the second conveying roller 42 to generate a relative displacement towards or away from the first conveying roller 41, so as to realize the clamping and releasing of the steel plate 100. In this way, when winding up the steel plate 100, the third telescopic driving member 43 drives the second conveying roller 42 to cooperate with the first conveying roller 41 to clamp it, and after the second conveying roller 42 and the first conveying roller 41 rotate, the steel plate 100 can be conveyed towards the end close to the winder.

[0041] Referring to Figure 1 , in this embodiment, the guiding assembly 5 is arranged on the frame 1 and on the side of the rolling assembly 3 close to the winder; the guiding assembly 5 includes a guiding roller 51, a guiding plate 52 and a fourth telescopic driving member 53. The guiding roller 51 is fixedly installed on the frame 1 through a bearing, the guiding roller 51 can freely rotate around its own axis, and the rotational axis of the guiding roller 51 is parallel to the rotational axis of the second conveying roller 42. The guiding plate 52 is specifically a flat plate made of high-strength steel, and its surface can be polished to reduce the friction force; one side of the guiding plate 52 is rotatably connected to the frame 1 on the side of the guiding roller 51 close to the winder, and the top surface of the guiding plate 52 is used to receive the steel plate 100.

[0042] The fourth telescopic driving member 53 can be a pneumatic cylinder or a hydraulic cylinder. The fourth telescopic driving member 53 is fixed on the frame 1, and its output end is rotatably connected to the end of the guide plate 52 away from the frame 1 to drive the end of the guide plate 52 away from the frame 1 to move closer to or farther from the reel. In this way, the guide roller 51 can prevent the steel plate 100 from being offset or bending too much to produce creases when entering the reel; the guide plate 52 can provide stable support for the end of the steel plate 100 when it first enters the reel; the fourth telescopic driving member 53 can drive the guide plate 52 closer to or farther from the reel according to actual needs. When the guide plate 52 needs to be used, it can be moved to a position close to the reel; when it is not needed, the guide plate 52 can be withdrawn to avoid interference with other operations.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the limit assembly 6 is arranged on the side of the clamping assembly 2 away from the conveying assembly 4 to limit the lateral displacement of the steel plate 100 when it is rolled up; the limit assembly 6 includes a first limit roller 61, two limit rings 62, a connecting rod 63, a contact roller 64 and a fifth telescopic driving member 65; the first limit roller 61 and the limit ring 62 are both made of stainless steel, and the surface can be polished to reduce friction; the first limit roller 61 is fixedly installed on the frame 1 through a bearing, and the first limit roller 61 can rotate freely around its own axis, and the rotation axis of the first limit roller 61 is parallel to the rotation axis of the guide roller 51.

[0044] The two limiting rings 62 are slidably arranged on the first limiting roller 61 and are respectively located on both sides of the steel plate 100. The sides of the two limiting rings 62 that are close to each other slide against the two sides of the steel plate 100 respectively. The limiting rings 62 are threadedly connected with fastening screws, and the limiting rings 62 can be fixed on the first limiting roller 61 by the fastening screws. In this way, by adjusting the position of the limiting ring 62 on the first limiting roller 61 according to the width of different steel plates 100, and fixing it on the first limiting roller 61 by the fastening screws, it is possible to effectively limit the steel plates 100 of different widths in the axial direction of the first limiting roller 61, and prevent the steel plates 100 from lateral displacement.

[0045] Reference Figure 1, in this embodiment, one end of the connecting rod 63 is rotatably connected to the frame 1; the abutting roller 64 is disposed opposite to the first limiting roller 61, and the abutting roller 64 is rotatably disposed at the end of the connecting rod 63 away from the frame 1, and the abutting roller 64 is in rolling abutment with the surface of the steel plate 100 away from the first limiting roller 61; the fifth telescopic driving member 65 can be one of a cylinder or a hydraulic cylinder. The fifth telescopic driving member 65 is fixed on the frame 1, and its output end is rotatably connected to the middle of the connecting rod 63 to drive the end of the connecting rod 63 away from the frame 1 to approach or move away from the steel plate 100. In this way, the abutting roller 64 and the first limiting roller 61 cooperate with each other to firmly clamp the steel plate 100 between the two, effectively preventing the steel plate 100 from breaking away from the restriction of the first limiting roller 61 and the limiting ring 62 during the winding process.

[0046] Referring to Figure 1 , in this embodiment, the cutting machine 7 is disposed between the rolling press assembly 3 and the conveying assembly 4 for precisely cutting and segmenting the steel plate 100 to ensure that the length of the steel plate 100 meets the production requirements.

[0047] The implementation principle of this Embodiment 1 is as follows: When winding the steel plate 100, the steel plate 100 passes through the limiting assembly 6, the clamping assembly 2, the conveying assembly 4, the cutting machine 7, the rolling press assembly 3, and the guiding assembly 5 in sequence and is then connected to the winding machine. The limiting assembly 6 can limit the lateral offset of the steel plate 100 during winding. Specifically, according to the widths of different steel plates 100, the positions of the two limiting rings 62 on the first limiting roller 61 are adjusted and fixed on the first limiting roller 61 by fastening screws. The two limiting rings 62 are respectively in sliding abutment with the two side edges of the steel plate 100, thereby effectively limiting the steel plate 100 in the axial direction of the first limiting roller 61 to prevent the steel plate 100 from experiencing lateral offset. The clamping assembly 2 and the rolling press assembly 3 can provide appropriate and effective tension for steel plates 100 with different thicknesses to enhance the quality and tightness of the winding of the steel plate 100. Specifically, when winding the thin steel plate 100, since the required winding force is small, only the frictional force between the first clamping plate 21 and the second clamping plate 22 and the upper and lower surfaces of the steel plate 100 can provide appropriate tension for the steel plate 100; while when winding the thick steel plate 100, because a greater winding force is required, at this time, multiple first pressing rollers 31 and second pressing rollers 32 in the rolling press assembly 3 can be used to press the steel plate 100 into a state similar to a "wavy" shape. In this way, the steel plate 100 must overcome its own deformation resistance during winding, thereby increasing the tension applied to the steel plate 100 and ensuring that the thick steel plate 100 can also be tightly wound; the cutting machine 7 precisely cuts and segments the steel plate 100 according to production requirements. The conveying assembly 4 can achieve the active conveying of the steel plate 100 to continuously convey the steel plate 100 into the winding machine after the steel plate 100 is cut. The guiding roller 51 in the guiding assembly 5 can prevent the steel plate 100 from being offset or having too large a bending angle and generating creases when entering the winding machine; the guiding plate 52 can provide stable support for the steel plate 100 when the end of the steel plate 100 first enters the winding machine.

[0048] Example 2 Reference Figure 3 and Figure 4 In this example, the main difference from Example 1 is that the limiting component 6 includes four second limiting rollers 66, a sixth telescopic driving member 67, a limiting block 68, and an elastic member 69. Specifically, in this example, the four second limiting rollers 66 are arranged on the rack 1 in a vertically staggered manner. Two of the second limiting rollers 66 are fixed to the rack 1 through bearing seats and roll against the lower surface of the steel plate 100. These two second limiting rollers 66 can freely rotate around their own axes, and the rotation axes are parallel to the horizontal plane and perpendicular to the conveying direction when the steel plate 100 is being wound up. The other two second limiting rollers 66 are slidably mounted on the rack 1 through slide rails and roll against the upper surface of the steel plate 100. The slide rails can specifically adopt linear guide rails or ball guide rails to ensure the smoothness and accuracy of sliding. These two limiting rollers can also freely rotate around their own axes, and the rotation axes are also parallel to the horizontal plane and perpendicular to the conveying direction when the steel plate 100 is being wound up.

[0049] The sixth telescopic driving member 67 can be one of a cylinder or a hydraulic cylinder. The sixth telescopic driving member 67 is fixed to the rack 1, and its output end is connected to the second limiting roller 66 on one side of the upper surface of the steel plate 100 to drive the second limiting roller 66 on one side of the upper surface of the steel plate 100 and the second limiting roller 66 on the lower surface of the steel plate 100 to generate relative displacement towards or away from each other. In other embodiments, the number of the second limiting rollers 66 can also be set to be more.

[0050] Reference Figure 4 and Figure 5 In this example, a plurality of relief grooves 661 are evenly spaced along the axial direction and the circumferential direction of the rolling surface of the second limiting roller 66. The relief grooves 661 are rectangular, and the distance between the adjacent inner side walls of adjacent relief grooves 661 is less than the dimensions in the length direction and the width direction of the relief grooves 661 themselves. The extending direction of the relief grooves 661 is parallel to the direction of the centrifugal force when the rotating shaft rotates. The relief grooves 661 on the two second limiting rollers 66 on the same side of the steel plate 100 are arranged in a staggered manner along the axial direction of the second limiting roller 66.

[0051] The limit block 68 is specifically a cemented carbide block whose shape matches the shape of the give way groove 661 and has high strength and wear resistance; the surface of the limit block 68 can be polished to reduce friction; the limit block 68 is slidably set in the give way groove 661, and the sliding direction of the limit block 68 is parallel to the extension direction of the give way groove 661; the elastic member 69 is a spring, the elastic member 69 is set in the give way groove 661 and is located between the second limit roller 66 and the limit block 68, one end of the elastic member 69 is fixed on the bottom surface of the give way groove 661, and the other end is fixed on the limit block 68; the elastic member 69 can make the limit block 68 pop out of the opening of the give way groove 661 and abut against the upper surface or lower surface of the steel plate 100. In this way, when the steel plate 100 passes through the second limiting roller 66, the limiting block 68 located within the width range of the steel plate 100 is pressed by the steel plate 100 and retracts into the clearance groove 661, while the limiting block 68 located outside the width range of the steel plate 100 pops out of the clearance groove 661 under the action of the elastic member 69, wherein the side walls of the limiting block 68 closest to the two sides of the steel plate 100 can fit closely to the two sides of the steel plate 100, thereby effectively limiting the displacement of the steel plate 100 in the width direction. In other embodiments, the limiting block 68 can also be made of titanium alloy; the shapes of the limiting groove and the limiting block 68 can also be other shapes, such as cylindrical.

[0052] Reference Figure 3 and Figure 4 In this embodiment, a sealed air cavity 662 is formed between the bottom side of the stopper 68 close to the clearance groove 661 and the clearance groove 661; an air jet hole 681 is provided on the stopper 68, one end of the air jet hole 681 is connected to the air cavity 662, and the other end of the opening extends to the side of the stopper 68 that rolls against the steel plate 100. In this way, when the steel plate 100 abuts against and presses down the stopper 68, the stopper 68 moves to the depth of the clearance hole and compresses the air cavity 662, so that the gas in the air cavity 662 is ejected at high speed from the air jet hole 681 to blow away the dust and impurities on the surface of the steel plate 100.

[0053] A first one-way valve 8 is provided in the jet hole 681, and the first one-way valve 8 is used to prevent external gas from entering the air cavity 662 from the jet hole 681; a connecting channel 663 is provided on the second limiting roller 66, and one end of the connecting channel 663 is connected to the air cavity 662, and the other end of the opening extends to the end surface of the second limiting roller 66 to communicate with the outside world; a second one-way valve 9 is provided in the connecting channel 663, and the second one-way valve 9 is used to prevent the internal gas of the air cavity 662 from being discharged from the connecting channel 663 to the outside world. In this way, when the limiting block 68 pops up and resets to inhale the outer wall gas, the external gas can only enter the air cavity 662 through the connecting channel 663, which prevents the gas from carrying dust and impurities near the steel plate 100 into the air cavity 662 when it is inhaled from the jet hole 681.

[0054] The implementation principle of Example 2 is as follows: when the steel plate 100 passes through the second limiting roller 66 and rolls against the second limiting roller 66, the limiting block 68 located within the width range of the steel plate 100 is subjected to the pressure of the steel plate 100 and is withdrawn into the clearance groove 661. During the displacement of the limiting block 68 to the depth of the clearance hole, the air cavity 662 is compressed, so that the volume of the air cavity 662 is reduced, the internal air pressure is increased, and the gas in the air cavity 662 is ejected from the jet hole 681 at high speed to sweep the dust and impurities on the surface of the steel plate 100. At the same time, the limiting block 68 located outside the width range of the steel plate 100 pops out of the clearance groove 661 under the action of the elastic member 69, wherein the limiting block 68 closest to the two sides of the steel plate 100 can fit closely to the two sides of the steel plate 100, thereby effectively limiting the displacement of the steel plate 100 in the width direction. This adaptive limiting method does not require manual adjustment and is suitable for steel plates 100 of different widths. Furthermore, by staggering the clearance grooves 661 on the two second limiting rollers 66 on the same side and reducing the spacing between the adjacent inner walls of the adjacent clearance grooves 661, the limiting blocks 68 on one second limiting roller 66 can cross-fill the gap between the adjacent limiting blocks 68 on the other second limiting roller 66. The limiting areas formed when the limiting blocks 68 contact the steel plates 100 are denser and more continuous, thereby reducing the lateral movement space of the steel plates 100 and improving the stability and accuracy of the steel plates 100 when they are rolled up.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
