Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, and in particular to an automatic feeding device for rolling material leveling and slitting. Background Technology

[0002] Stainless steel products are typically manufactured by uncoiling and straightening the coil, followed by shearing and punching. This process requires auxiliary equipment for uncoiling and feeding the coil, but existing uncoiling and feeding equipment has a simple structure and needs improvement.

[0003] Chinese Patent CN218193688U discloses an automatic feeding system for slitting and leveling steel coils. The device includes a loading trolley, a pressing head mechanism, a material handling mechanism, a front swing bridge, and a rear swing bridge. The loading trolley is positioned in front of the uncoiler to transport the steel coil to it. The pressing head mechanism is located between the uncoiler and the clamping device, above the uncoiler, to press down the steel coil placed on the uncoiler. The material handling mechanism is located at the discharge end of the uncoiler to receive the sheet material after uncoiling. The front and rear swing bridges are positioned opposite each other between the end-aligning shear and the alignment device to lift the conveyed sheet material, align it through the alignment device, and then allow it to enter the slitting machine. This system allows the entire feeding process of the steel coil between the uncoiler, the initial alignment machine, and the slitting machine to be completed automatically with the push of a button, reducing the feeding time and improving work efficiency.

[0004] However, the device still has shortcomings: the device has a simple leveling structure for coils, while coils often have a certain degree of elasticity. After being wound for a long time, they will maintain a certain curvature. Conventional leveling equipment needs to slow down the feeding speed when straightening them so that the steel plate will not return to its bent state due to its own elasticity after being flattened, thus reducing processing efficiency.

By setting up a positioning mechanism, the coil is positioned to prevent it from deviating during the feeding process and to ensure the straightness and stability of the steel plate during feeding.

[0026] Example 1

[0027] like Figures 1-4As shown, this utility model proposes an automatic feeding device for slitting and leveling rolled materials, comprising a base 1, a support shaft 3, guide rollers A4 and B5, a drive assembly A, a positioning mechanism, and a pushing mechanism. Two fixed frames 2 are symmetrically arranged on the base 1, each with a slot 201. The two ends of the support shaft 3 are respectively inserted into the corresponding slots 201 and rotatably connected to their inner walls. The two ends of the guide rollers A4 are rotatably connected to the corresponding fixed frames 2, and two connecting rods A6 are symmetrically arranged on the guide rollers A4 and rotatably connected to them. The two ends of the guide rollers B5 are rotatably connected to the corresponding connecting rods A6. The drive assembly A is mounted on the base 1 and drives the guide rollers B5 to rotate around the axis of the guide rollers A4. Drive assembly A includes a movable plate 7, a connecting rod B8, and a hydraulic cylinder A9. Two fixed plates are arranged parallel to each other on the base 1, and several guide rods perpendicular to them are arranged between the two fixed plates. The movable plate 7 is located between the two fixed plates and is slidably connected to the guide rods. One end of the connecting rod B8 is rotatably connected to the movable plate 7, and the other end is rotatably connected to the guide roller B5. The body of the hydraulic cylinder A9 is mounted on the base 1, and the output end of the hydraulic cylinder A9 is connected to the movable plate 7. A positioning mechanism is mounted on the base 1. In the working state, the positioning mechanism clamps and limits both ends of the roll of material sleeved on the support shaft 3 to prevent the roll from deviating during the unloading process. The positioning mechanism includes a slide 10, a fixing ring A11, a clamping ring A12, and a bidirectional module 1001. There are two slides 10, arranged parallel to each other between two fixing frames 2 and slidably connected to the base 1. The fixing ring A11 is coaxially sleeved on the support shaft 3 and connected to the corresponding slide 10. The fixing ring A11 has a side groove A aligned with the slot 201. The clamping ring A12 is sleeved on the support shaft 3 and rotatably connected to the corresponding fixing ring A11. The clamping ring A12 has a side groove B adapted to the side groove A. The body of the bidirectional module 1001 is connected to the base 1, and its two output ends are respectively connected to the corresponding slides 10. A counterweight 121 is provided on the arc surface of the clamping ring A12, so that when the clamping ring A12 is not in operation, the counterweight 121 aligns the side groove B with the side groove A. A pushing mechanism is mounted on the base 1. In operation, the pushing mechanism moves the roll material that passes over guide rollers A4 and B5. The pushing mechanism includes a bracket 16, a support roller 17, a motor 18, a pressure roller 20, and a drive assembly B. The drive assembly B includes a hydraulic cylinder B21. The bracket 16 is mounted on the base 1. The support roller 17 is rotatably connected to the bracket 16 and parallel to the support shaft 3. The motor 18 is mounted on the bracket 16, and its output end is connected to the support roller 17. A U-shaped frame 19 is slidably mounted on the bracket 16. The pressure roller 20 is rotatably connected to the U-shaped frame 19. The hydraulic cylinder B21 is mounted on the bracket 16 and drives the U-shaped frame 19 to rise or fall.

[0028] It should be noted that hydraulic cylinders A9 and B21 are both connected to an external hydraulic pump, and motor 18 is a servo motor. Flexible rubber anti-slip pads are fitted on the arc surfaces of support roller 17 and pressure roller 20.

[0029] In this embodiment, the support shaft 3 is threaded through the central roll of the coil material, and the two ends of the support shaft 3 are placed in the corresponding slots 201 using a forklift (or other equipment). Since side slot A and slot A201 are directly opposite each other and their openings face the same direction, and side slot B is directly opposite slot A201 under the weight of the counterweight 121, the placement of the support shaft 3 is not obstructed. The fixing wires of the coil material are then untied, and the end of the steel plate (or steel strip) is pulled and aligned accordingly. Figure 1 As shown, the material passes through the gap between guide roller A4 and guide roller B5. Hydraulic cylinder A9 is activated, pushing movable plate 7 to slide. This, in turn, uses connecting rod B8 to rotate guide roller B5 around the axis of guide roller A4. The cooperation between guide roller B5 and guide roller A4 initially straightens the bent coil, which has been in a coiled state for a long time. Next, the end of the steel plate is pulled through the gap between support roller 17 and pressure roller 20. Hydraulic cylinder B21 is activated, driving U-shaped frame 19 downwards and causing pressure roller 20 to slide down as well. The pressure roller 20, in conjunction with support roller 17, clamps the steel plate. Then, bidirectional module 1001 is activated, causing the two side slides 10 to move closer together. This uses clamping ring A12 to clamp and position both ends of the coil, ensuring the coil does not deviate during unloading. Finally, hydraulic cylinder 18 is activated, driving support roller 17 to rotate, thus gradually unloading the steel plate. The coil on support shaft 3 then adaptively rotates with support shaft 3.

[0030] Example 2

[0031] like Figure 2 and Figure 3 As shown, the automatic feeding device for slitting and leveling rolled materials proposed in this utility model, compared with Embodiment 1, has a positioning component on the guide roller A4. The positioning component is linked with the positioning mechanism. The positioning component includes two fixing rings B13, both of which are sleeved on the guide roller A4 and located at both ends of the guide roller A4. The two fixing rings B13 are respectively connected to the corresponding side slide 10, and a clamping ring B14 that rotates coaxially with the two fixing rings B13 is respectively provided on the side of the two fixing rings B13 that are close to each other. The guide roller B5 is also provided with a positioning component, and the two fixing rings B13 on the guide roller B5 are respectively connected to the corresponding side fixing rings B13 on the guide roller A4 through connecting rods C15.

[0032] In this embodiment, as the two sets of carriages 10 move closer or further apart, the clamping rings B14 on both sides of the guide rollers A4 and B5 move closer or further apart simultaneously. The clamping rings B14 assist in positioning the steel plate during transport, thereby further improving the stability and straightness of the steel plate (or steel strip) during the transport process.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
