Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading of high-frequency electric furnaces, and particularly relates to an automatic loading and unloading device for high-frequency electric furnaces. Background Art

[0002] The automatic loading and unloading device for high-frequency electric furnaces is a highly integrated and automated system, which can realize functions such as automatic feeding, discharging and monitoring of high-frequency electric furnaces. Through this device, manual operation can be greatly reduced, and production efficiency and product quality can be improved.

[0003] The automatic loading and unloading device for high-frequency electric furnaces usually includes a storage system, a conveying system, a heating system and a discharging system. The storage system is used to store raw materials to be processed. The conveying system is responsible for conveying the raw materials from the storage system to the feeding port of the high-frequency electric furnace. The conveying system can adopt different forms, such as vibrating conveying, belt conveying, etc., depending on the type and size of the raw materials. The heating system can heat the materials. The discharging system can realize automatic discharging.

[0004] However, the structure of the conveying system in the existing automatic loading and unloading device for high-frequency electric furnaces is relatively complex. Usually, mechanical claws or conveying plates are used to directly place the materials at the feeding port of the high-frequency electric furnace, resulting in high costs and low conveying efficiency. Summary of the Utility Model

[0005] In order to solve the technical problems that the structure of the conveying system in the existing automatic loading and unloading device for high-frequency electric furnaces is relatively complex, and in order to achieve precise conveying, usually mechanical claws or conveying plates are used to directly place the materials at the feeding port of the high-frequency electric furnace, resulting in high costs and low conveying efficiency, the utility model provides an automatic loading and unloading device for high-frequency electric furnaces.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0007] An automatic loading and unloading device for a high-frequency electric furnace includes a feeding mechanism. The feeding mechanism includes a feeding conveying structure. The discharging end of the feeding conveying structure is connected to the feeding end of the feeding conveying structure. The feeding conveying structure can convey materials into the feeding conveying structure. A plurality of pushing mechanisms are arranged in the conveying direction of the feeding conveying structure. The pushing mechanism includes a push rod. The push rod is arranged perpendicular to the conveying direction on the conveying plane of the feeding conveying structure. A plurality of inclined guide plates are also arranged in the conveying direction of the feeding conveying structure. The guide plates are arranged opposite to the pushing mechanisms one by one. The top of the guide plate is butted against the feeding conveying structure. The bottom of the guide plate is connected to the feeding trough body. The feeding trough body has two open ends. A guiding mechanism is arranged at one end of the feeding trough body close to the guide plate. The guiding mechanism includes a guiding rod. An electric heating tube is arranged at the end of the feeding trough body far from the guide plate. The electric heating tube has two open ends. The guiding rod can push the materials in the feeding trough body into the electric heating tube.

[0008] With the above structural solution, the feeding and conveying structure conveys the material to the feeding and conveying structure. When the material is conveyed to the discharge end of the feeding and conveying structure, the push rod of the pushing mechanism extends, pushing the material to the position of the guiding plate opposite in position, pushing the material out of the conveying plane of the feeding and conveying structure. Under the action of gravity, the material is conveyed along the inclined guiding plate to the material trough of the corresponding feeding trough body. The guiding rod of the guiding mechanism extends and retracts along one end of the feeding trough body close to the guiding plate to the other end, continuously pushing the material entering the feeding trough body along the length direction of the feeding trough body into the electric heating tube. When the heating time of the material in the electric heating tube is sufficient, under the push of the guiding rod, the material with sufficient heating time is pushed out of the electric heating tube, and the unheated material is pushed into the electric heating tube. There are multiple pushing mechanisms, guiding plates, feeding trough bodies, guiding mechanisms, feeding trough bodies and electric heating tubes, and they are arranged in one-to-one correspondence, timely distributing the materials from the feeding and conveying structure, adapting to the conveying speed of the materials of the feeding and conveying structure, so as to continuously heat and improve work efficiency. In this application, the pushing mechanism and the guiding plate are used to guide the material into the corresponding feeding trough body, with a simple structure, and can timely distribute the materials from the feeding and conveying structure, with high efficiency.

[0010] As a preferred implementation manner of an automatic loading and unloading device for a high-frequency electric furnace, there are two feeding and conveying structures, and the two feeding and conveying structures are located on both sides of the feeding and conveying structure in the conveying direction. On the side of each feeding and conveying structure away from the feeding and conveying structure at the discharge end, there is a telescopic mechanism, and the telescopic mechanism includes a telescopic rod. The telescopic rod is arranged perpendicular to the conveying direction on the conveying plane of the feeding and conveying structure, and the telescopic rod can push the material from the feeding and conveying structure into the feeding and conveying structure.

[0011] With the above structural solution, due to the heating frequency of the electric heating tube, the different heating times required for different batches of materials, and the possible equipment abnormalities of the feeding equipment, there may be a situation of short supply in feeding. In this embodiment, two bar automatic loading machines are set up to cooperate with each other for emergencies to ensure sufficient feeding volume.

[0012] As a preferred implementation manner of an automatic loading and unloading device for a high-frequency electric furnace, the feeding and conveying structure is a conveyor belt type conveying structure.

[0033] Refer to Figures 1-5, this embodiment provides an automatic loading and unloading device for a high-frequency electric furnace, including a loading mechanism. The loading mechanism includes a bar automatic loader 1 and a loading conveyor structure 2. The bar automatic loader 1 is a stepped loader, and the discharge end of the bar automatic loader 1 is connected to the feed end of the loading conveyor structure 2. The loading conveyor structure 2 is a belt-type conveyor structure, and the discharge end of the loading conveyor structure 2 is connected to the feed end of the feed conveyor structure 3. The loading conveyor structure 2 can convey materials into the feed conveyor structure 3. There are two loading conveyor structures 2, and the two loading conveyor structures 2 are located on both sides of the conveying direction of the feed conveyor structure 3. On one side of the discharge end of each loading conveyor structure 2 away from the feed conveyor structure 3, there is a telescopic mechanism 9. The telescopic mechanism 9 includes a telescopic rod, and the telescopic rod is arranged perpendicular to the conveying direction on the conveying plane of the feed conveyor structure 3. The telescopic rod can push the materials from the loading conveyor structure 2 into the feed conveyor structure 3.

[0034] The feed conveyor structure 3 is a belt-type conveyor structure. There are several pusher mechanisms 4 arranged in the conveying direction of the feed conveyor structure 3. The pusher mechanism 4 includes a push rod, and the push rod is arranged perpendicular to the conveying direction on the conveying plane of the feed conveyor structure 3. There are also several inclined guide plates 5 arranged in the conveying direction of the feed conveyor structure 3. The guide plates 5 are arranged in one-to-one correspondence with the pusher mechanisms 4. The top of the guide plate 5 is docked with the feed conveyor structure 3, and the bottom of the guide plate 5 is connected to the feed chute 6. The feed chute 6 has openings at both ends. A guiding mechanism 7 is provided at one end of the feed chute 6 close to the guide plate 5. The guiding mechanism 7 is a pneumatic or electric guiding mechanism 7. The guiding mechanism 7 includes a guiding rod. An electric heating tube 8 is provided at one end of the feed chute 6 away from the guide plate 5. The electric heating tube 8 has openings at both ends. The guiding rod can push the materials in the feed chute 6 into the electric heating tube 8.

[0035] The loading conveyor structure 2, the feed conveyor structure 3, the pusher mechanism 4, the guiding mechanism 7, and the electric heating tube 8 are all connected to the controller. The controller is controlled by a PLC, centrally controlling the connection of each working part, without causing blockage or idleness, automatically adjusting the working speed between each part, so that they work in coordination to exert the best performance of the whole set of equipment. At the same time, it ensures energy conservation when the equipment runs slowly and the safety of the equipment in case of special accidents. It coordinates according to different working state data of the electric furnace to realize automatic loading, automatic heating, and discharging, reducing manual intervention.

[0036] The working principle of this embodiment is as follows:

[0037] Each bar automatic loading machine 1 conveys bar-shaped materials to the conveying plane of its respective corresponding loading conveying structure 2. After the loading conveying structure 2 conveys the materials to a position connected to the feeding conveying structure 3, the telescopic mechanism 9 drives the telescopic rod to extend and retract, pushing the materials from the conveying plane of the loading conveying structure 2 to the conveying plane of the feeding conveying structure 3, and the feeding conveying structure 3 continues to convey the materials. When the feeding conveying structure 3 conveys the materials to the discharge end of the feeding conveying structure 3, the push rod of the pushing mechanism 4 extends, pushing the materials to the position of the guide plate 5 opposite in position, and pushing the materials out of the conveying plane of the feeding conveying structure 3. Under the action of gravity, the materials are conveyed along the inclined guide plate 5 to the material trough of the corresponding feeding trough body 6. The guide rod of the guiding mechanism 7 extends and retracts along one end of the feeding trough body 6 close to the guide plate 5 to the other end, continuously pushing the materials entering the feeding trough body 6 along the length direction of the feeding trough body 6 into the electric heating tube 8. When the heating time of the materials in the electric heating tube 8 is sufficient, under the push of the guide rod, the materials with sufficient heating time are pushed out of the electric heating tube 8, and the unheated materials are pushed into the electric heating tube 8. The pushing mechanism 4, the guide plate 5, the feeding trough body 6, the guiding mechanism 7, the feeding trough body 6 and the electric heating tube 8 are all provided with multiple ones, and are arranged in one-to-one correspondence, timely distributing the materials from the loading conveying structure 2, adapting to the conveying speed of the materials of the loading conveying structure 2, so as to continuously carry out heating and improve work efficiency.

[0038] In this embodiment, the loading conveying structure 2 and the feeding conveying structure 3 are both linear conveyors. In addition to being able to linearly convey the materials, the loading conveying structure 2 and the feeding conveying structure 3 can also temporarily store the materials. During the storage period, the materials are arranged with the same interval, which is convenient for the next link to work.

[0039] The materials in this embodiment are bar-shaped materials.

[0040] In this embodiment, the end in the conveying direction of the loading conveying structure 2 is not sealed, and directly below the end, there is a feeding trough body 6. Similar to other feeding trough bodies 6, this feeding trough body 6 also corresponds to a guiding mechanism 7 and an electric heating tube 8. The difference is that this feeding trough body 6 does not have a corresponding pushing mechanism 4 and guide plate 5.

[0041] In this embodiment, the bar automatic loading machine 1 is a stepped loading machine. The stepped loading machine is an existing device. The stepped loading machine uses a multi-stage push plate to reciprocate upward to achieve the automatic loading function. According to the production requirements and the layout of the on-site dimensions, push plates of different heights and the number of push plates are designed, with 3 - 7 levels available. Storage bins of different sizes are designed to maximize efficiency and improve the degree of automation.

[0042] Due to the heating frequency of the electric heating tube 8, the different heating durations required for materials in different batches, and the possible equipment abnormalities of the feeding equipment, there may be a situation where the supply falls short of demand during feeding. In this embodiment, two bar automatic feeding machines 1 are provided and cooperate with each other to meet emergencies and ensure sufficient feeding volume.

[0043] In this embodiment, the feeding speed of the feeding mechanism 7 matches the heating speed of the electric heating tube 8, and the relationship between the two can be set.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
