Description

Technical Field

[0001] The utility model relates to the technical field of ultra-thin strip steel coiling, in particular to a wrinkle-proof roller device for rolling ultra-thin strip steel. Background Art

[0002] A steel strip refers to a conveyor belt made of carbon steel as the traction and carrying member of a belt conveyor, and can also be used for bundling goods; it is a narrow and long steel plate produced by various rolling mills to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.

[0003] After the steel strip is rolled, the rolled steel strip will be coiled. At present, the domestic basically adopts the direct coiling method. However, for the 1 / 4 wave of the rolled plate type with high requirements, especially for ultra-thin materials, this method is extremely easy to form roller ribs, resulting in difficult coiling. At present, the solution is to appropriately reduce the rolling tension (coiling tension), but this method is prone to produce diagonal rib marks (rib patterns), and the rolled steel plate type is also not good, making it difficult for the subsequent processes to proceed smoothly. Therefore, we propose a wrinkle-proof roller device for rolling ultra-thin strip steel to solve the above problems. Summary of the Utility Model

[0004] The utility model aims at the defect that for the 1 / 4 wave of the rolled plate type with high requirements, especially for ultra-thin materials, the direct coiling method is extremely easy to form roller ribs, resulting in difficult coiling in the prior art, and provides a wrinkle-proof roller device for rolling ultra-thin strip steel.

[0005] The utility model is realized by the following technical solutions:

[0006] A wrinkle-proof roller device for rolling ultra-thin strip steel includes a rotating shaft, and both ends of the rotating shaft are provided with cylinders for driving its rotation, and a plurality of support mechanisms are arranged on the rotating shaft;

[0007] The support mechanism includes a shaft sleeve sleeved on the rotating shaft. One side of the shaft sleeve is fixed with a mounting seat through a connecting plate. Both ends of the mounting seat are rotatably installed with support rollers, and the strip steel is supported by the support rollers to reduce the wrinkles during the coiling of the strip steel.

[0008] In a preferred embodiment of the utility model, both ends of the rotating shaft are fixed with mounting ear plates. The included angle between the side projection of the mounting ear plate and the side projection of the connecting plate is 30° to 90°, and the telescopic end of the cylinder is hinged to the mounting ear plate, so that the cylinder can drive the rotating shaft better, and then the support roller contacts the strip steel to support it.

[0009] In a preferred embodiment of the present utility model, the outer ends of the two support rollers at both ends of the mounting seat are inclined upward, and the angle between the two support rollers is 170° to 175°. When the strip steel is supported by the support rollers, the strip steel in the running process is gathered towards the middle, playing a certain positioning role for the strip steel during the moving process.

[0010] In a preferred embodiment of the present utility model, a rubber layer is provided on the surface of the support roller. The setting of the rubber layer provides a certain protection for the strip steel when the device is working, preventing the support roller from scratching the strip steel.

[0011] In a preferred embodiment of the present utility model, the bushing is rotatably connected to the rotating shaft, and a torsion spring is provided at the rotational connection between the bushing and the rotating shaft. Moreover, a limiting opening is provided at one end of the bushing, and a limiting rod adapted to the limiting opening is fixed on the rotating shaft. The limiting rod is inserted into the limiting opening, and the rotational angle of the bushing is restricted through the cooperation of the limiting rod and the limiting opening.

[0012] In a preferred embodiment of the present utility model, the limiting opening is arc-shaped, and the radian of the limiting opening is 10° to 20°, specifically restricting the rotational angle of the bushing on the rotating shaft.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By adding a set of anti-wrinkle roller devices between the tension roller and the winding roller, and adjusting the air pressure through a pneumatic device, it is ensured that the strip steel is unfolded during the rolling process, playing an anti-wrinkle function. The entire device consists of three parts: a cylinder, a support roller, and a control system. The support roller is pressed between the tension roller and the winding roller. On the one hand, the distance between the two rollers is reduced, greatly reducing the coiling risk. Most importantly, the support roller is driven by a cylinder and will automatically adjust the top pressure applied to the strip steel by the anti-wrinkle roller according to the rolling tension, thereby ensuring that the strip steel is unfolded without changing the rolling tension, truly playing the role of unfolding and anti-wrinkle.

Detailed implementation mode

[0020] The following combines the attached drawings to elaborate on the preferred embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0021] As Figures 1-4 shown, an anti-wrinkle roller device for rolling ultra-thin strip steel, its specific installation position on the coiler is as Figure 4 shown. The coiler includes a frame 1. A tension roller 3 is arranged at the front end of the frame 1, and a rewinding roller 2 is arranged at the rear end. The anti-wrinkle roller device 4 is located below the rewinding roller 2 and is also located between the tension roller 3 and the rewinding roller 2;

[0022] The anti-wrinkle roller device 4 includes a rotating shaft 41. The rotating shaft 41 is installed between the frames 1. At both ends of the rotating shaft 41, cylinders 42 for driving its rotation are arranged. The cylinders 42 are connected to an external air pump, and the air pressure can be adjusted at any time. At both ends of the rotating shaft 41, mounting ear plates 43 are fixed. The included angle between the side projection of the mounting ear plate 43 and the side projection of the connecting plate 45 is 30° to 90°. And the telescopic end of the cylinder 42 is hinged to the mounting ear plate 43, and the bottom end of the cylinder 42 is hinged to the inner wall of the frame 1, so that the cylinder 42 can drive the rotating shaft 41 better, and then make the supporting roller 47 contact the strip steel to support it;

[0023] At the same time, a plurality of support mechanisms are arranged on the rotating shaft 41. The number of support mechanisms is four, which is determined according to the number of strip steel cuts;

[0024] Among them, the support mechanism includes a bushing 44 sleeved on the rotating shaft 41. One side of the bushing 44 is fixed with a mounting seat 46 through a connecting plate 45. At both ends of the mounting seat 46, supporting rollers 47 are rotatably installed. A rubber layer is arranged on the surface of the supporting roller 47. The arrangement of the rubber layer provides a certain protection for the strip steel during the operation of the device, avoiding the supporting roller 47 from scratching the strip steel, and supporting the strip steel through the supporting roller 47 to reduce the wrinkles during strip steel rewinding.

[0025] Specifically, the outer ends of the two support rollers 47 at both ends of the mounting base 46 are inclined upward, and the angle between the two support rollers 47 is 170° to 175°. When the strip steel is supported by the support rollers 47, the strip steel in the running process is gathered towards the middle, playing a certain positioning role for the strip steel during the moving process.

[0026] Furthermore, when the rotating shaft 41 is driven to rotate by the air cylinder 42, the angle of the entire rotating shaft is adjusted, causing all the support rollers 47 to rotate simultaneously. However, sometimes the running trajectories of the cut strip steels are slightly different, and it is difficult for all the support rollers 47 to rotate simultaneously to fit different cut strip steels.

[0027] Therefore, in this device, the bushing 44 is rotationally connected to the rotating shaft 41, and a torsion spring 49 is provided at the rotational connection between the bushing 44 and the rotating shaft 41. One end of the bushing 44 is provided with a limit opening 441, and a limit rod 48 adapted to the limit opening 441 is fixed on the rotating shaft 41. The limit rod 48 is inserted into the limit opening 441, and the rotational angle of the bushing 44 is restricted by the cooperation between the limit rod 48 and the limit opening 441. The limit opening 441 is arc-shaped, and the radian of the limit opening 441 is 10° to 20°. Specifically, the rotational angle of the bushing 44 on the rotating shaft 41 is restricted. After the air cylinder 42 drives the rotating shaft 41 to rotate and the support roller 47 contacts the strip steel to support it, during the running process of the strip steel, the strip steel can squeeze the corresponding support roller 47, and then through the torsion spring 49, it can maintain the contact state with the strip steel, and automatically adjust the top pressure exerted by the support roller 47 on the strip steel according to the rolling tension.

[0028] In this embodiment, by adding a set of anti-wrinkle roller device 4 between the tension roller 3 and the winding roller 2, the air pressure is adjusted through a pneumatic device. The pneumatic device is the air cylinder 42, which pushes the rotating shaft 41 to rotate, and then makes the support roller 47 rotate, so that it fits the bottom of the strip steel, ensuring that the strip steel is unfolded during the rolling process and playing an anti-wrinkle function. The entire device consists of three parts: the air cylinder 42, the support roller 47, and the control system. The control system is the system that controls the operation of the coiler. The support roller 47 presses between the tension roller 3 and the winding roller 2. On the one hand, the distance between the two rollers is reduced, greatly reducing the coiling risk. At the same time, relying on the air cylinder 42 to drive the support roller 47, the top pressure exerted by the anti-wrinkle roller on the strip steel can be automatically adjusted according to the rolling tension. Further, through the setting of the torsion spring 49, the top pressure on each support roller 47 can be precisely controlled, so as to ensure that the strip steel is unfolded without changing the rolling tension, truly playing an anti-wrinkle function.

[0029] It should be noted that the parts not involved in the present utility model are the same as or can be implemented by the prior art; various drives in the present utility model can be realized by corresponding power structures such as air cylinders, oil cylinders, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.

[0030] In the description of the embodiments of the present utility model, unless otherwise clearly defined and limited, the terms "installed", "connected", "coupled", "arranged", "provided with", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
