Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a magnetic belt conveyor with double pressure rollers. Background Art

[0002] Magnetic belt conveyor is a kind of strip conveying equipment often used in the unwinding part of cold-rolled strip processing line. Its function is to attract and convey the head of the steel coil to the steering pinch roller. The magnetic belt conveyor mainly includes a frame, a driven roller, an active roller, an endless belt, a gear motor, a magnet, a pressure roller and a hydraulic cylinder. The gear motor is used to drive the active roller to rotate, and the driven roller rotates together under the friction of the endless belt. The magnet is fixed on the frame and close to the endless belt to absorb the strip below. The hydraulic cylinder drives the frame to swing, so that the frame approaches or moves away from the steel coil. When the frame approaches the steel coil, only the pressure roller is allowed to press the steel coil, and the frame or belt must not press the steel coil, otherwise it will damage the magnet and the conveyor equipment. In addition, the gap between the frame or belt and the steel coil should not be too large, otherwise it will be difficult for the magnet to absorb the strip, thus affecting the normal operation of the magnetic belt conveyor. The diameter of incoming steel coils is generally in the range of 900mm to 2200mm. When the magnetic belt conveyor is equipped with only a single roller, in order to enable the roller to press the steel coils in all diameter ranges, the gap between the frame or belt and the steel coils in the small diameter range will become larger, and the magnet will find it difficult to attract the strip steel, and the magnetic belt conveyor will not be able to transport the strip steel backward. If the gap between the frame or belt and the steel coils in the small diameter range is reduced to meet the requirements, the large diameter steel coils cannot be put into production, because at this time the frame or belt has pressed the steel coils, but the roller has not yet pressed the steel coils. This situation is absolutely not allowed, and the position of the roller can only be readjusted.

[0003] Therefore, it is necessary to design a magnetic belt conveyor with double pressure rollers to overcome the above problems. Utility Model Content

[0023] like Figure 1-Figure 2The utility model provides a magnetic belt conveyor with double pressure rollers, including a frame 1 and an endless belt 5. The two ends of the frame 1 are respectively provided with a driven roller 2 and an active roller 3. The endless belt 5 is wrapped around the driven roller 2 and the active roller 3. The active roller 3 is connected to a gear motor 4. When the gear motor 4 drives the active roller 3 to rotate, the driven roller 2 rotates together with the friction of the endless belt 5. The two ends of the active roller 3 along the axial direction are provided with fixed slewing bearings 10. The magnetic belt conveyor with double pressure rollers also includes a hydraulic cylinder 7 that can drive the frame 1 to swing around the fixed slewing bearing 10, and a plurality of magnets 6 for adsorbing the strip steel 11. One end of the hydraulic cylinder 7 is hinged with the fixed frame. The other end of the hydraulic cylinder 7 is hinged to the frame 1, and the hydraulic cylinder 7 is arranged above the frame 1. The magnet 6 is fixed on the frame 1 and is close to the lower inner surface of the endless belt 5, and maintains a certain gap with the lower inner surface of the endless belt 5. Each magnet 6 is evenly spaced on the frame 1. The end of the frame 1 equipped with the driven roller 2 is also equipped with a pressure roller mounting frame, and the pressure roller mounting frame is equipped with an inner pressure roller 8 that can be used to press small-diameter steel coils and an outer pressure roller 9 that can be used to press large-diameter steel coils. The inner pressure roller 8 and the outer pressure roller 9 are both located on the side of the driven roller 2 away from the active roller 3.

[0024] The utility model provides a magnetic belt conveyor with double pressure rollers.
