Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of roll material processing equipment, and more specifically, to a leveling device for roll material after unwinding. Background Technology
[0002] Aluminum sheets are typically stored in coils. During aluminum sheet processing, the aluminum coil needs to be unwound first, then cut and stamped into products. However, due to internal stress present after the aluminum sheet is coiled, it becomes difficult for the aluminum sheet to be stamped into high-quality products by a stamping machine. Therefore, a leveling device is needed to treat the unwound aluminum sheet to eliminate the impact of internal stress on the stamping process.
[0003] The currently used leveling machine consists of a frame and a leveling mechanism. The frame is a box-shaped structure, and the leveling mechanism is installed inside the frame. Conveyor rollers are installed at both ends of the frame. The leveling mechanism includes a drive motor and multiple leveling rollers. The drive motor is fixedly connected to the side plate of the frame. The multiple leveling rollers are evenly divided into upper and lower groups. The output shaft of the drive motor is fixedly connected to one of the lower leveling rollers. Both ends of the upper and lower leveling rollers are rotatably connected to the side plate of the frame. The distance between the upper and lower leveling rollers is equal to the thickness of the roll material. The upper leveling roller presses down on the roll material on the lower leveling roller to perform the leveling operation. In use, the roll material is conveyed to the gap between the upper and lower leveling rollers via the conveyor roller at one end of the frame. The drive motor drives the lower leveling roller to rotate, causing the roll material to move towards the conveyor roller at the other end of the frame. The upper leveling roller then presses down on the roll material to perform the leveling work. After leveling, the roll material is output from the conveyor roller at the other end of the leveling mechanism. However, leveling the roll material solely by pressing down on it with the upper leveling roller results in poor stress relief, affecting the quality of the stamped products. Utility Model Content
[0004] The purpose of this invention is to provide a leveling device for unwinding rolled materials, which can eliminate internal stress in the rolled materials and improve the leveling effect of the rolled materials.
[0005] This utility model is achieved through the following technical solution:
[0006] A leveling device for unwinding rolled materials includes a frame, within which a rolled material mechanism, a guiding mechanism, a pretreatment mechanism, a rolling mechanism, and a leveling mechanism are sequentially arranged. The pretreatment mechanism has staggered upper and lower straightening rollers arranged sequentially along the direction of rolled material movement, forming an S-shaped straightening path between them. Both the upper and lower straightening rollers are rotatably connected to the frame. The rolling mechanism includes a conveyor belt and a rolling element, the rolling element being movably connected to the frame and located directly above the conveyor belt.
[0007] Furthermore, the guiding mechanism includes a guide roller, both ends of which are rotatably connected to the frame.
[0008] Furthermore, a mounting plate is provided on the frame, and a cylinder is provided on the mounting plate. The piston rod of the cylinder is fixedly connected to the rolling element.
[0009] Furthermore, the rolling element includes a pressure plate, and a plurality of rolling rollers are arranged below the pressure plate, with both ends of the rolling rollers being rotatably connected to the pressure plate.
[0010] Furthermore, baffles are provided on both sides of the conveyor belt, and an electric telescopic rod is provided between the baffles and the frame, with the drive end of the electric telescopic rod fixedly connected to the baffle.
[0011] Furthermore, a guide plate is provided at one end of the baffle near the pretreatment mechanism, and the guide plate is inclined.
[0012] Furthermore, the roll material mechanism includes a roll material shaft, the two ends of which are rotatably connected to the frame.
[0013] Furthermore, the leveling mechanism includes a vertically arranged upper leveling roller and a lower leveling roller, both of which are horizontally arranged and perpendicular to the direction of roll material movement, and both of which are rotatably connected to the frame.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0015] In this invention, the S-shaped straightening path formed by the staggered distribution of the upper and lower straightening rollers allows the material to bend alternately. This alternating bending gradually releases the internal stress of the material, resulting in more uniform stress. The roller pressing components and conveyor belt can roll the alternately bent material, achieving multi-plane synchronous straightening. This alternating rolling further releases the stress in the aluminum material from top to bottom, left to right, and internally, improving the stress elimination effect and ensuring the quality of the stamped products. Finally, a leveling mechanism levels the stress-relieved material, effectively improving the leveling effect of the coil. Attached Figure Description

[0026] Example 1
[0027] like Figures 1-3 As shown, this embodiment provides a leveling device after unwinding a roll material, including a frame 1. The frame 1 contains a roll material mechanism 2, a guiding mechanism 3, a pretreatment mechanism 4, a rolling mechanism 5, and a leveling mechanism 6 arranged sequentially. The pretreatment mechanism 4 has an upper straightening roller 42 and a lower straightening roller 41 arranged in an alternating manner along the roll material movement direction. An S-shaped straightening path is formed between the upper straightening roller 42 and the lower straightening roller 41. Both the upper straightening roller 42 and the lower straightening roller 41 are rotatably connected to the frame 1. The rolling mechanism 5 includes a conveyor belt 51 and a rolling element. The rolling element is movably connected to the frame 1 and located directly above the conveyor belt 51.
[0028] The S-shaped straightening path formed by the staggered distribution of the upper straightening roller 42 and the lower straightening roller 51 allows the material to bend alternately. Through this alternating bending action, the internal stress of the material is gradually released, making the stress uniform. The rolling components and the conveyor belt 51 can roll the alternately bent material to achieve multi-plane synchronous straightening. Through alternating rolling, the stress in the upper, lower, left, right, and internal parts of the aluminum material is further released, improving the stress elimination effect and ensuring the quality of the stamped products. Then, the leveling mechanism 6 levels the material after eliminating internal stress, effectively improving the leveling effect of the coil.
[0029] In a specific embodiment of this invention, the guiding mechanism 3 includes a guide roller 31, both ends of which are rotatably connected to the frame 1.
[0030] In this specific embodiment, a mounting plate 54 is provided on the frame 1, and a cylinder 55 is provided on the mounting plate 54. The piston rod of the cylinder 55 is fixedly connected to the rolling element. The distance between the rolling element and the conveyor belt 51 can be adjusted by the cylinder 55, which can adjust the rolling pressure and avoid material damage caused by over-straightening.
[0031] In a specific embodiment of this invention, the rolling element includes a pressure plate 52, and a plurality of rolling rollers 53 are disposed below the pressure plate 52. Both ends of the rolling rollers 53 are rotatably connected to the pressure plate 52. The piston rod of the cylinder 55 is fixedly connected to the pressure plate 52 by welding or bolting.
[0032] In a specific embodiment of this invention, baffles 56 are provided on both sides of the conveyor belt 51, and an electric telescopic rod 58 is provided between the baffles 56 and the frame 1. The drive end of the electric telescopic rod 58 is fixedly connected to the baffles 56. The baffles 56 can position the unwound aluminum sheet, prevent the aluminum sheet from tilting, and improve the rolling effect of the rolling roller 53 on the aluminum sheet.
[0033] In a specific embodiment of this invention, a guide plate 57 is provided at one end of the baffle 56 near the pretreatment mechanism 4, and the guide plate 57 is inclined. The guide plate 57 can guide the aluminum sheet, further improving the positioning effect of the aluminum sheet.
[0034] In a specific embodiment of this invention, the roll material mechanism 2 includes a roll material shaft 21, and both ends of the roll material shaft 21 are rotatably connected to the frame 1.
[0035] In this specific embodiment, the leveling mechanism 6 includes a vertically arranged upper leveling roller 61 and a lower leveling roller 62. Both the upper and lower leveling rollers 61 and 62 are horizontally arranged and perpendicular to the direction of roll material movement. Both are rotatably connected to the frame 1. The material, after alternating bending and rolling, is then leveled by the pressure of the upper and lower leveling rollers 61 and 62. This orderly structural design improves the leveling effect of the roll material. It should be noted that the roll shaft 21, guide roller 31, upper leveling roller 61, and lower leveling roller 62 are all connected to a power mechanism, which is a common power supply device, such as a motor.
[0036] The aluminum coil on the coil shaft 21 is unwound. The unwound material passes sequentially through the guide roller 31, the lower straightening roller 41, the upper straightening roller 42, the conveyor belt 51, the rolling roller 53, the upper leveling roller 61, and the lower leveling roller 62. The upper straightening roller 42 and the lower straightening roller 41 bend the material alternately. The conveyor belt 51 and the rolling roller 53 work together to roll the material. The upper leveling roller 61 and the lower leveling roller 62 work together to press the material again. By first eliminating the internal stress of the coil through alternating bending and rolling, and then leveling, the leveling effect of the coil can be effectively improved.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
