Description

Technical Field

[0001] This utility model relates to a curved plate turning and feeding device, and more particularly to an intelligent turning and feeding device for curved solid waste plates. Background Technology

[0002] In the field of solid waste treatment, some large-volume solid wastes, such as discarded furniture and discarded wind turbine blades, need to be cut into boards before crushing and other processing. When the boards have a curvature, their feeding direction will affect the crushing effect, and in severe cases, it will cause the crushing equipment to jam or even be damaged.

[0003] To avoid problems such as reduced crushing efficiency and equipment jamming caused by incorrect feeding direction, it is necessary to adjust the feeding direction of the curved solid waste sheet. Currently, the solid waste treatment field mainly relies on manual judgment of the sheet orientation, which is inefficient and prone to errors.

[0004] Later related patents, such as the intelligent feeding shape adjustment system with authorization publication number CN 115816707 A, include components such as a material transfer frame, a steering motor, and photosensitive sensors. It can identify the direction of the wind turbine blade cutting the sheet material through the signal of the photosensitive sensor matrix and realize the flipping and adjustment of the sheet material. However, this patented device can only realize the 180° vertical flipping of the sheet material and cannot realize the 90° rotation of the sheet material at the edge.

[0005] The patent with publication number CN 214358751 U is a steering and feeding device that includes three sets of drive components that can be combined to achieve horizontal rotation and vertical lifting of materials. However, this patented device requires the material to be placed into an overlapping structure that matches the device's supporting structure. It is mainly used in the field of product cleaning and is not suitable for solid waste board feeding yards. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings of the existing technology by providing an intelligent steering and feeding device for curved plates. This device can identify the feeding direction of the curved plates and achieve in-situ steering of the plates, thereby avoiding reduced crushing efficiency or equipment damage caused by incorrect feeding direction and improving processing efficiency.

[0007] To achieve the above objectives, this utility model provides an intelligent steering and feeding device for arc-shaped sheet metal, comprising a conveyor belt and a support base. The device is characterized by: lifting elements on opposite sides of the support base in the same direction as the conveyor belt; the upper ends of the telescopic rods of the lifting elements are hinged to their respective support plates; the two support plates are at the same height; a material tray is placed on the two support plates; the lower middle part of the material tray is connected to the output shaft of a reducer via a universal joint; the input shaft of the reducer is connected to a drive device; a laser emitter and a controller are respectively provided on opposite sides of the support base perpendicular to the direction of the conveyor belt, both of which are higher than the material tray.

[0008] The aforementioned lifting components can be hydraulic cylinders, pneumatic cylinders, or electric push rods, and their corresponding telescopic rods are the piston rods of hydraulic cylinders or pneumatic cylinders or the lead screws of electric push rods. The aforementioned drive device can be an electric motor, a pneumatic motor, or a hydraulic motor; all of them can drive the material tray to rotate through a reducer and a universal joint. In operation, the curved plate is conveyed to the loading tray via a conveyor belt. The laser emitter continuously emits laser light of fixed power and frequency to the controller. The controller receives the laser light and converts the laser signal into a control signal. If the curvature of the curved plate is perpendicular to the line connecting the laser emitter and the controller, the curved plate can only briefly block the laser light emitted by the laser emitter. If the controller receives the laser light within a preset time, it determines that the plate feeding direction is correct and there is no need to rotate the loading tray. It is only necessary to control the extension rod of the lifting element of the adjacent conveyor belt to extend and the extension rod of the other lifting element to retract, so that the loading tray tilts. The plate is tilted and placed into the feed inlet of the next processing equipment. If the curvature of the curved plate is aligned with the line connecting the laser emitter and receiver, and the curved plate continuously blocks the laser emitted by the laser emitter, the controller will not receive the laser for more than a preset time. In this case, it is determined that the plate feeding direction is incorrect. The material tray is rotated 90 degrees by the drive device, and then the plate is placed into the feed inlet of the next processing equipment by two lifting elements. It can be seen that this utility model can identify the feeding direction of the curved plate and realize the turning of the plate, so as to avoid the reduction of crushing efficiency or equipment damage caused by the incorrect feeding direction of the plate and improve the processing efficiency. As a further improvement of this utility model, the material tray is a circular or regular polygonal plate, and the universal joint is located at the center of the material tray; it can realize the in-situ rotation of the plate and accurately control the feeding direction of the plate. As a further improvement of this utility model, the two lifting elements are aligned with the center of the material tray; this can prevent the material from deflecting during discharge. This invention can identify the feeding direction of curved plates and realize the in-situ rotation of the plates, avoiding reduced crushing efficiency or equipment damage caused by incorrect feeding direction of the plates, and improving processing efficiency.

[0014] The present invention will be further described below with reference to the accompanying drawings. like Figures 1 to 3 As shown, an intelligent steering and feeding device for arc-shaped sheet metal in this embodiment includes a conveyor belt 1 and a support base 2. Hydraulic cylinders 3 and 4, which serve as lifting elements, are provided on opposite sides of the support base 2 in the same direction as the conveyor belt. The upper ends of the piston rods of the hydraulic cylinders 3 and 4 are hinged to their respective support plates 5 or 6 through hinge joints 7. The two support plates 5 and 6 are at the same height. A circular material tray 8 is placed on the two support plates 5 and 6. The lower end of the center of the material tray 8 is connected to the output shaft of the reducer 10 through a universal joint 9. The input shaft of the reducer 10 is connected to the motor 11. The two hydraulic cylinders 3 and 4 are on the same straight line as the center of the material tray 8. A laser emitter 12 and a controller 13 are respectively provided on opposite sides of the support base 2 perpendicular to the direction of the conveyor belt through support rods. The laser emitter 12 and the controller 13 are both higher than the material tray 8.

[0015] Waste wind turbine blade plates with an arc of 0.45, an arc length of 1000mm, a width of 800mm, and a thickness of 40mm are used as raw materials. The arc direction of the raw materials is parallel to the material's travel direction, and the raw material plates are placed on the conveyor belt with the convex side facing up. The running speed of the conveyor belt is 4m / s.

[0016] In operation, the curved plate 16 is conveyed to the loading tray 8 via the conveyor belt 1. The laser emitter 12 continuously emits laser light of fixed power and frequency to the controller 13. The controller 13 receives the laser light and converts the laser signal into a control signal. Figure 4 As shown, when the curvature orientation of the curved plate 16 is perpendicular to the line connecting the laser emitter 12 and the controller 13, the curved plate 16 can only briefly block the laser emitted by the laser emitter 12. If the controller 13 receives the laser within a preset time (e.g., 6 seconds), it determines that the plate feeding direction is correct and there is no need to rotate the loading plate 8. It only needs to control the piston rod of the hydraulic cylinder 3 adjacent to the conveyor belt 1 to extend 250mm and the piston rod of the other hydraulic cylinder 4 to retract 250mm, so that the loading plate 8 tilts and remains tilted for a period of time, discharging the plate into the feed inlet 17 of the next processing equipment; Figure 5As shown, when the arc orientation of the curved plate 16 is consistent with the line connecting the laser emitter 12 and the receiver 13, and the curved plate 16 continuously blocks the laser emitted by the laser emitter 12, if the controller 13 cannot receive the laser after a preset time, it is determined that the feeding direction of the plate is incorrect. First, the motor 11 and the reducer 10 rotate the loading plate 8 by 90 degrees, and then the lifting hydraulic cylinders 3 and 4 discharge the plate into the feed port 17 of the next processing equipment. According to the control signal of the controller 13, the action of the motor 11 and the two hydraulic cylinders 3 and 4 can be manually controlled, or the controller 13 can be connected to the hydraulic system of the motor 11 and the two hydraulic cylinders 3 and 4 through the automatic control system to realize the automatic control of the action of the motor 11 and the two hydraulic cylinders 3 and 4. Through the two hinge joints 7 and the universal joint 9, the two support plates 5 and 6 and the loading plate 8 can be tilted within a certain angle to discharge the material smoothly. It can be seen that this utility model can identify the feeding direction of the arc-shaped plate and realize the turning of the plate, avoid the reduction of crushing efficiency or equipment damage caused by incorrect feeding direction of the plate, and improve the processing efficiency; the loading plate 8 is a circular or regular polygonal plate, and the universal joint 9 is located at the center of the loading plate 8, which can realize the in-situ turning of the plate and accurately control the feeding direction of the plate. This utility model is not limited to the above-described embodiments. For example, the above-described lifting element can be a cylinder or an electric push rod, and the corresponding telescopic rods are the piston rod of the cylinder or the lead screw of the electric push rod. Motor 11 can also be replaced by a pneumatic motor or a hydraulic motor, or it can drive the material tray 8 to rotate through reducer 10 and universal joint 9; The above embodiments have been used to illustrate the invention, but it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the invention to the scope of the described embodiments.
