Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and specifically discloses an automatic feeding device. Background Technology

[0002] Because discarded electrical materials contain a large amount of heavy metals and harmful substances, improper disposal or incineration can cause serious pollution to soil, water sources and air, posing a potential threat to human health and the ecological environment. Professional recycling and treatment can effectively reduce environmental pollution and protect the ecological balance. In particular, copper and aluminum, as well as other metal materials in cables and steel-cored aluminum stranded wires, are valuable resources. Recycling and reuse can not only save raw materials but also reduce production costs and achieve effective recycling of resources.

[0003] Currently, in the production lines for disassembling power cables and steel-cored aluminum stranded wire, the feeding process is mostly carried out using a combination of human and machine operations or purely manual operation. For different types and sizes of hardware and electrical materials, the operators are used to feeding them at their usual speed and at a fixed angle on the equipment. This often causes jams and shutdowns, or uneven feeding, requiring manual material handling on the production line later on, resulting in low production efficiency. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1-4This utility model discloses an automatic tilting and feeding device, including a hydraulic station 1. One end of the hydraulic station 1 is provided with a hydraulic pipeline 2, and the other end of the hydraulic pipeline 2 is connected to the machine body (i.e., the frame in the invention) 3. A guide plate 4, a rotating shaft 5 and a sensor 6 are installed on the machine body 3. An anti-tilt plate 7 is installed as a guardrail on the machine body 3 and the feeding platform 8. A hydraulic locking mechanism 9 and a positioning mechanism 10 are installed in the feeding platform 8. A hydraulic drive mechanism 11 drives the rotating shaft 5 and the feeding platform 8 to tilt through a connecting flange 12. The machine body 3, the feeding platform 8 and the hydraulic drive mechanism 11 are installed on a base 13.

[0020] The feeding platform 8 is located at the top of the machine body 3. The hydraulic locking mechanism 9 is located on both sides of the feeding platform 8. The positioning mechanism 10 is installed in the feeding platform 8. The sensors 6 are installed on both sides of the machine body 3 and both sides of the feeding platform 8. The locking mechanism 9 and the hydraulic drive mechanism 11 are connected through a hydraulic system. The sensors 6 installed on both sides of the machine body 3 identify the material status and send information to the control system. The control system controls the motor to drive the oil pump to rotate and the solenoid valves on the relevant hydraulic pipelines to open and close, thus completing the power transmission to the hydraulic drive mechanism 11.

[0021] The equipment's workflow is as follows:

[0022] Before using this equipment, the angle of the guide plate needs to be adjusted according to the type and quantity of materials transferred to the feeding platform 8. After the sensor 6 detects that the material is within the range specified by the positioning mechanism 10 and confirms that there is no error, the hydraulic locking device 9 fixes the container holding the material.

[0023] Based on factors such as the real-time current and operating time of the decomposition production line, the hydraulic drive mechanism 11 drives the loading platform 8 to rotate via the connecting flange 12 and the rotating shaft 5.

[0024] During the flipping process, sensor 6 controls the start, stop and speed of hydraulic drive mechanism 11 based on factors such as material state, quantity, current of decomposition equipment, and running time.

[0025] During the flipping process, the material will slide out along the guide plate 4, and the slid-out material will connect with the feed conveyor of the decomposition production line.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
