Description

Technical Field

[0001] The invention belongs to the technical field of material scrap dragging machines, and in particular relates to a flexible scrap dragging machine with adjustable tension. Background Art

[0002] Aluminum products are made from aluminum and other alloying elements. They are typically processed into castings, forgings, foils, plates, strips, tubes, bars, and profiles, followed by cold bending, sawing, drilling, assembly, and painting. Aluminum is the primary metal element, and alloying elements are added to enhance its performance. Aluminum processing technology is categorized into castings, heat-treatable alloys, and non-heat-treatable alloys.

[0003] In the aluminum processing industry, the residual waste after scrap trimming needs to be transported to the scrap edge winding and curling equipment for centralized recycling. In order to ensure that the aluminum scrap can be completely transported to the scrap edge winding and curling equipment, it is necessary to have a certain conveying force and a certain flexibility to prevent the scrap edge from breaking during the transportation process, which makes it impossible to carry out subsequent continuous winding. Therefore, the existing solution basically relies on the suction fan to transport through the closed air duct. The advantage of this method is that it can greatly reduce the probability of scrap edge breakage and damage, but at the same time, the fan power consumption is large, and the scrap edge is easily displaced or entangled during the transportation process, which makes the scrap edge unable to enter the winding and curling equipment smoothly, thereby causing the scrap edge to break. Summary of the Invention

[0004] The present invention relates to a scrap edge dragging machine with flexible and adjustable tension, comprising a dragging assembly, a flexible transmission assembly, a power assembly and a frame. A flexible transmission assembly and a power assembly are provided above the frame, the power assembly is provided above the right side of the frame, and the flexible transmission assembly is provided above the middle part of the frame. One end of the flexible transmission assembly is connected to the power assembly, and the other end of the flexible transmission assembly is connected to the dragging assembly. The scrap edge is directly dragged by adopting a direct dragging method, and the dragging transmission mechanism is a flexible transmission assembly. The dragging force is flexibly transmitted, and the problem of synchronous transportation is solved by relying on flexibility to prevent the scrap from breaking during dragging. In addition, this method has a simple structure and can meet production needs while greatly reducing energy consumption. It also does not require a complex photoelectric synchronization system, and is convenient for production and maintenance.

One end of the driven worm gear shaft and the driving worm gear shaft are both provided with teeth. The teeth are provided inside the oil cavity. The other end of the driving worm gear shaft is connected to a coupling. The other end of the driven worm gear shaft is connected to a drag assembly. The rigid transmission of the motor is converted into a flexible transmission through oil transmission. The speed of the drag assembly can be automatically adjusted according to the friction between the waste sheet and the drag assembly, thereby preventing the waste sheet from being damaged and broken by the force of the drag assembly during the dragging process.

[0008] The dragging assembly includes a drag wheel, a pressure roller, a connecting rod and a torsion spring. The dragging wheel is in the shape of a cylinder. One end of the dragging wheel is connected to the driven worm gear shaft. A pressure roller is provided above the dragging wheel. The pressure roller is in the shape of a cylinder.

The other end of the connecting rod is connected to the torsion spring. The torsion spring is longitudinally arranged behind the fixed bearing seat. Through the pressure roller and the torsion spring, a downward pressure can be applied to the waste sheet on the dragging wheel, so that the waste sheet can be dragged and moved when the dragging wheel rotates, and this method can also adapt to the uneven surface of the waste sheet to exert downward pressure on it.

[0009] The bearing seat bracket is connected with the fixed bearing seat and the adjusting bearing seat, so that the main parts of the frame and the flexible transmission component are supported by the fixed bearing seat and the adjusting bearing seat.

[0010] The oil cavity is provided with oil, and the oil fills the oil cavity to ensure that the filled oil can better perform oil transmission and reduce the power loss caused by the oil transmission. Beneficial effects

[0011] Due to the adoption of direct dragging, the present invention greatly reduces energy consumption in production that meets the same function, has a simple structure, and the dragging force is flexibly transmitted. The synchronization problem is solved by flexibility, and a complex photoelectric synchronization system is not required, which is convenient for production and maintenance. The rigid transmission of the motor is converted into a flexible transmission through the oil transmission method, and the rotation speed of the dragging component can be automatically adjusted according to the action of the waste sheet and the friction force of the dragging component, thereby preventing the waste sheet from being damaged and broken by the force of the dragging component during the dragging process, ensuring that the full oil can better perform oil transmission, and reducing the power loss caused by the oil transmission.

[0019] Implementation examples;

[0020] The motor 12 is installed on the frame 13. The motor 12 is connected to the active turbine shaft 9 by a coupling 11. The active turbine shaft 9 and the driven turbine shaft 7 are installed in the fixed bearing seat 6, the adjustable bearing seat 10, and the oil cavity 8 through the bearing 5.

[0021] The oil chamber 8 is filled with oil, and the motor 12 rotates, driving the active turbine shaft 9 through the coupling 11. The teeth on the active turbine shaft 9 drive the oil in the oil chamber 8 to form an axial vortex, which drives the driven turbine shaft 7 and the drag wheel 1 to rotate in the same direction. The belt holding roller 2 rotates in the opposite direction due to friction. The scrap material to be dragged is passed between the drag wheel 1 and the belt holding roller 2, and the scrap material is dragged. Because the active turbine shaft 9 and the driven turbine shaft 7 are not in direct contact, but are flexibly connected by oil, when the drag force exceeds a certain value, the speed of the driven turbine shaft 7 is lower than that of the active turbine shaft 9, thereby generating a certain drag force. Rotating the adjustment nut 15 causes the active turbine shaft 9 to move radially within the oil chamber 8, approaching or moving away from the driven turbine shaft 7, and the drag force increases or decreases, achieving the purpose of adjusting the drag force.
