Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding structures, in particular to an automatic feeding structure of a magnetic core coating furnace. Background Art

[0002] Magnetic cores are components made of magnetic materials such as ferrite and alloys and have specific shapes (such as rings, E-shaped, and U-shaped). They are widely used in electronic components such as transformers and inductors. Magnetic cores require a core coating furnace because it forms a specific insulating or protective coating on the core surface, improving its performance and reliability, such as enhancing insulation and preventing rust. The core coating furnace features a loading mechanism to automate production and improve efficiency, accurately and quickly transporting the cores to be coated.

[0003] The loading structure of a traditional magnetic core coating furnace typically consists of a conveyor belt, a hopper, and a simple push mechanism. The hopper, used to store the magnetic cores to be processed, is typically located at a higher position, allowing gravity to naturally drop the cores onto the conveyor belt. The conveyor belt is usually driven by a motor and features anti-slip or positioning structures on its surface to ensure that the cores remain stable during transportation. When the cores are conveyed to the coating furnace entrance, the push mechanism activates, pushing the cores into the furnace. The push mechanism is a push rod driven by a pneumatic cylinder, hydraulic cylinder, or motor. Its movement is relatively simple, and it can only achieve linear movement.

[0004] Traditional core coating furnace loading systems typically utilize a hopper to store the cores to be processed. This lacks the ability to sort, orient, or sequence the cores, leaving them in a disordered state. This results in a significant degree of randomness in the position and orientation of the cores as they fall onto the conveyor belt, making it difficult to ensure accurate positioning during subsequent transport and entry into the coating furnace. The hopper allows the cores to naturally fall onto the conveyor belt due to gravity. This uncontrolled discharge method makes it impossible to control the discharge speed and flow rate of the cores, easily leading to core accumulation or clogging on the conveyor belt. Especially when the hopper is filled with a large number of cores, gravity causes the cores to fall at a rapid rate, impacting the conveyor belt and affecting its service life and stability. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an automatic feeding structure of a magnetic core coating furnace, which aims to improve the problem in the feeding structure of a traditional magnetic core coating furnace that when the number of magnetic cores in the hopper is large, gravity will cause the magnetic cores to fall at a faster speed, causing impact on the conveyor belt, affecting the service life and stability of the conveyor belt.

[0008] Furthermore, the transmission component includes a transmission platform, and the transmission platform is arranged on the side wall of the fixed bracket.

[0009] Furthermore, a plurality of fixed platforms are fixedly connected to the top of the transmission platform, and a side panel is fixedly connected to the side wall of each fixed platform.

[0010] Furthermore, the side wall of the fixing platform is fixedly connected to an electric motor, and the output end of the electric motor is fixedly connected to a gear fan.

[0012] Furthermore, a connecting shaft is fixedly connected to the side wall of the gear, and a plurality of cams are fixedly connected to the outer wall of the connecting shaft.

[0013] Furthermore, an airbag is fixedly connected to the bottom of each side panel, and a sliding column is slidably connected inside the side panel.

[0014] Furthermore, a limiting ring is fixedly connected to the top of each sliding column, and the sliding column sleeve is provided with a spring, one end of the spring is fixedly connected to the inside of the side plate, and the other end of the spring is fixedly connected to the inside of the limiting ring.
