Description

Technical Field

[0001] The utility model relates to the technical field of charging of intermediate frequency furnaces, in particular to an energy-saving automatic charging system for intermediate frequency furnaces. Background Technique

[0002] As is well known, an intermediate frequency furnace is a power supply device that converts 50HZ alternating current of industrial frequency into intermediate frequency. It rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into adjustable intermediate frequency current, which is supplied to the intermediate frequency alternating current flowing through the capacitor and the induction coil. High-density magnetic lines of force are generated in the induction coil, and the metal material placed in the induction coil is cut, generating a large eddy current in the metal material.

[0003] At present, during the charging process of existing intermediate frequency furnaces, an inclined frame and a hopper are generally used in cooperation. The material is stored in the hopper, and with the drive of the driving device, the hopper moves on the frame to the designated feeding position of the furnace body, and the material in the hopper is added to the furnace body. However, during use, it is often necessary to debug the inclination angle of the frame according to actual use requirements. After debugging, the hopper will be inclined, and it is necessary to debug the hopper again, which is relatively cumbersome to operate and not convenient to use. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an energy-saving automatic charging system for intermediate frequency furnaces, which solves the problem that the hopper still needs to be adjusted again after the inclination angle of the frame is debugged.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0006] An energy-saving automatic charging system for intermediate frequency furnaces includes a material storage member, a moving frame and a mounting frame. The hopper of the material storage member is rotationally connected to the quick-connect shaft seat at the upper end of the support frame through a connecting shaft. The bottom frame at the lower part of the support frame is slidably connected to the slide rail on the mounting frame, and the threaded sleeve at the lower part of the bottom frame is in threaded transmission connection with the bidirectional lead screw on the mounting frame. One end of the bidirectional lead screw is in transmission connection with the driving motor, and the sliding sleeve at the lower part of the bottom frame is slidably connected to the slide rail on the mounting frame.

[0007] Further, lifting ears are fixedly connected to both sides of the upper port of the hopper, and a pulling seat is fixedly connected to the outer wall of the bottom of the hopper.

[0008] Further, both ends of the slide rail are fixedly connected to the frame. The lower part of the bottom frame slides against the frame, and both ends of the bidirectional lead screw are rotationally connected to the frame through bearings. One end of the bidirectional lead screw passes through the frame and is fixedly connected to the output shaft of the driving motor, and the driving motor is fixedly connected to the frame;

[0009] Support feet are rotationally connected to both ends of the frame.

[0010] Further, the lapping seat of the quick-connect shaft seat is integrally formed and arranged at the upper end of the support frame. Limited stop blocks are rotatably connected to both ends of the upper part of the lapping seat through pin shafts, and an elastic spring plate is arranged between the limited stop blocks and the lapping seat.

[0011] The second connecting seat integrally arranged at the lower end of the limited stop block is matched with the first connecting seat arranged at the upper end of the lapping seat and is rotatably connected through a pin shaft. Both ends of the elastic spring plate are bent to form inserted ends, and the inserted ends are respectively fixedly inserted into the inserted slots opened at corresponding positions on the lapping seat and the limited stop block.

[0012] Compared with the prior art, the utility model provides an energy-saving intermediate-frequency furnace automatic feeding system, which has the following beneficial effects:

[0013] In the utility model, the hopper is rotatably connected to the moving frame body through a connecting shaft. During the adjustment of the inclination angle of the placement frame, the hopper can rotate on the quick-connect shaft seat at the top of the support frame under the action of gravity, ensuring that the hopper is always in a vertical state, so that it is in the best material storage state. At the same time, the connecting shaft and the quick-connect shaft seat cooperate to facilitate the quick disassembly and assembly of the hopper. The structure is simple and easy to use.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, an automatic feeding system for an energy-saving intermediate frequency furnace proposed in an embodiment of the present utility model includes a storage member 1, a moving frame body 2, and a placement frame 3. The hopper 101 of the storage member 1 is rotationally connected to the quick-connect shaft seat 202 at the upper end of the support frame 201 through a connecting shaft 102, ensuring that during use, regardless of how the installation inclination of the placement frame 3 is adjusted, the hopper 101 can rotate on the quick-connect shaft seat 202 on the support frame 201 under the action of the connecting shaft 102, so that the hopper 101 is always in a vertical state, avoiding the spilling of materials caused by the inclination of the hopper 101 and ensuring stable use. The bottom frame 203 at the lower part of the support frame 201 is slidably connected to the slide rail 302 of the placement frame 3. The hopper 101 is stably installed on the placement frame 3 by the cooperation of the support frame 201 and the bottom frame 203. During use, the hopper 101 and the materials placed therein are transported to the feeding part of the furnace body to ensure that the materials are smoothly added to the furnace body for processing. Moreover, the threaded sleeve 205 at the lower part of the bottom frame 203 is in threaded transmission connection with the bidirectional lead screw 303 on the placement frame 3, and one end of the bidirectional lead screw 303 is in transmission connection with the driving motor 304. When adding materials, the driving motor 304 runs to transmit power to the moving frame body 2 through the cooperation of the bidirectional lead screw 303 and the threaded sleeve 205, so that the moving frame body 2 drives the hopper 101 to slide on the placement frame 3 to the feeding part of the furnace body, and then the materials in the hopper 101 are smoothly added to the furnace body. In addition, the sliding sleeve 204 at the lower part of the bottom frame 203 is slidably connected to the slide rail 302 of the placement frame 3, and the cooperation of the sliding sleeve 204 and the slide rail 302 is used to improve the sliding stability of the moving frame body 2 on the placement frame 3, avoiding the moving frame body 2 from toppling and falling off the placement frame 3 during the sliding process and ensuring stable use.

[0022] As Figure 1 and Figure 2As shown, in some embodiments, hoisting ears 103 are fixedly connected to both sides of the upper port of the hopper 101, ensuring that during use, the entire storage member 1 can be stably hoisted by auxiliary hoisting equipment and moved to a designated position, improving the convenience of disassembling and assembling the storage member 1. Moreover, a pulling seat 104 is fixedly connected to the outer wall of the bottom of the hopper 101, facilitating fixing a pulling rope or other connecting member to the pulling seat 104 when the hopper 101 pours materials into the furnace body. Subsequently, it is used in conjunction with a pulling device to pour the materials into the furnace body and complete the addition of the materials.

[0023] As Figure 1 and Figure 5 As shown, in some embodiments, both ends of the slide rail 302 are fixedly connected to the frame 301, facilitating the formation of an orbit for the reciprocating sliding of the moving frame body 2 on the mounting frame 3, ensuring that the moving frame body 2 can smoothly move the hopper 101 on the mounting frame 3 and move the hopper 101 to a designated position of the furnace body, so as to add the materials in the hopper 101 to the furnace body for processing. The lower part of the bottom frame 203 slides and abuts against the frame 301 to ensure that the entire moving frame body 2 can smoothly slide and adjust its position on the mounting frame 3. Moreover, both ends of the bidirectional lead screw 303 are rotatably connected to the frame 301 through bearings. One end of the bidirectional lead screw 303 passes through the frame 301 and is fixedly connected to the output shaft of the driving motor 304, and the driving motor 304 is fixedly connected to the frame 301, ensuring that during the operation of the driving motor 304, the bidirectional lead screw 303 smoothly rotates on the frame 301, thereby driving the entire moving frame body 2 and the hopper 101 thereon to smoothly move on the mounting frame 3;

[0024] Support feet 305 are rotatably connected to both ends of the frame 301, facilitating the use of the support feet 305 to lap the frame 301 at a designated use position, ensuring the stable use of the entire mounting frame 3 at the use position. At the same time, the rotatable connection mode between the support feet 305 and the frame 301 can be appropriately rotated during use as the installation inclination angle of the mounting frame 3 varies, so as to stably install the mounting frame 3 and ensure stable use.

[0025] As Figure 3 and Figure 4As shown, in some embodiments, the overlapping seat 2021 of the quick-connect shaft seat 202 is integrally formed at the upper end of the support frame 201, facilitating the formation of a convenient connecting member for a shaft member at the top of the support frame 201, thereby ensuring that the hopper 101 can be quickly and conveniently disassembled and assembled on the moving frame 2 through the connecting shafts 102 on both sides, improving the convenience of use. Both ends of the upper part of the overlapping seat 2021 are rotatably connected with limit blocks 2023 through pin shafts 2025, facilitating the stable installation of the limit blocks 2023 on the overlapping seat 2021, forming an anti-drop limit component for a shaft member on the upper part of the overlapping seat 2021, ensuring that the shaft member can be stably connected to the quick-connect shaft seat 202. At the same time, the upper end of the limit block 2023 is bent to form an arc-shaped abutting head. When the shaft member abuts against the limit block 2023, it can push the limit block 2023 to rotate on the overlapping seat 2021, enabling the shaft member to be smoothly connected to the quick-connect shaft seat 202, improving the convenience of operation. And an elastic spring plate 2026 is arranged between the limit block 2023 and the overlapping seat 2021 to ensure a stable supporting force is provided for the limit block 2023, ensuring that after the shaft member abuts and pushes the limit block 2023 to deflect, the limit block 2023 can be smoothly driven to reset, effectively limiting the shaft member, and improving the stability after the shaft member is installed, ensuring the stable installation of the hopper 101;

[0026] The second connecting seat 2024 integrally arranged at the lower end of the limit block 2023 is cooperatively arranged with the first connecting seat 2022 arranged at the upper end of the overlapping seat 2021 and is rotatably connected through a pin shaft 2025, facilitating the stable installation of the limit block 2023 on the overlapping seat 2021 by using the cooperation between the two, and ensuring that the limit block 2023 can rotate smoothly on the overlapping seat 2021, enabling the shaft member to be smoothly placed on or removed from the quick-connect shaft seat 202, improving the convenience of operation. And both ends of the elastic spring plate 2026 are bent to form insertion ends, and the insertion ends are respectively fixedly inserted into the insertion slots opened at the corresponding positions on the overlapping seat 2021 and the limit block 2023, ensuring the stable installation of the elastic spring plate 2026 on the overlapping seat 2021 and the limit block 2023, and further providing a stable and effective supporting force for the limit block 2023, ensuring that the limit block 2023 can effectively limit the shaft member and prevent the shaft member from falling off the quick-connect shaft seat 202.
