Description

Technical Field

[0001] This utility model relates to the field of magnetic core processing technology, specifically to a central column gap grinding and drying mechanism. Background Technology

[0002] In magnetic components, creating an air gap in the core post is a common design technique. Since the permeability of the core material is not infinite, when the magnetic flux through the core exceeds a certain threshold, it enters a state of magnetic saturation. At this point, the permeability drops sharply, the inductance decreases significantly, and the component performance deteriorates. The presence of an air gap introduces magnetic reluctance, reducing the effective permeability of the core and thus suppressing excessive magnetic flux growth, preventing premature saturation. To achieve this, a portion of the core post needs to be ground away to create the air gap. After grinding, the core needs to be cleaned. Water residue remains after cleaning, necessitating drying. Existing drying mechanisms typically blow hot air directly onto the core. However, since the core is stationary on a conveyor belt and has significant residual water, the drying effect is often poor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a central column gap grinding and drying mechanism, which solves the technical problem of poor drying effect in existing drying mechanisms.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a central column gap grinding and drying mechanism, including a housing, a conveying component is movably arranged inside the housing, two sets of shaking components installed at the bottom of the housing are connected to the bottom of the conveying component, a drying component installed at the top of the housing is provided above the conveying component, a discharge port is opened on the side wall of the housing corresponding to the horizontal level of the conveying component, and a discharge guide plate is installed at the position of the discharge port.

[0005] The vibration assembly includes a second motor mounted on the side wall of the housing. The output shaft of the second motor is fixedly connected to one end of a crankshaft rotatably connected to the bottom of the housing. Two connecting rods are hinged on the crankshaft, and the ends of the two connecting rods away from the crankshaft are hinged to a fixed frame through connecting blocks. The fixed frame is fixedly connected to the bottom of the transmission assembly.

[0006] Preferably, the conveying assembly includes a frame movably disposed inside the housing, with rollers rotatably connected to both ends of the frame, a motor fixedly connected to one of the rollers mounted on the side wall of the frame, a conveyor belt drivingly connecting the two rollers, multiple staggered and cross-distributed slow-feed baffles fixedly disposed on the inner wall of the frame, and a discharge baffle fixedly disposed inside the frame.

[0007] Preferably, both the slow-feed baffle and the discharge baffle are inclined.

[0008] Preferably, the side wall of the frame has a notch corresponding to the position of the discharge port.

[0009] Preferably, the inner wall of the housing is equipped with multiple sets of slide rails, and sliders that are fixed to the side wall of the frame are slidably arranged on the slide rails.

[0010] Preferably, the drying assembly includes an air duct installed at the top of the machine casing, with a fan and an electric heating element installed at the two ends of the air duct, and the electric heating element is positioned above the conveying assembly.

[0011] Preferably, the distance between the conveying component and the drying component is 15cm-25cm.

[0012] By employing the above technical solution, this utility model provides a central column gap grinding and drying mechanism, which has at least the following beneficial effects:

[0013] 1. This central column gap grinding and drying mechanism, by setting two sets of shaking components at the bottom of the conveying assembly, uses the shaking components to drive the entire conveying assembly to vibrate in the up and down direction. In this way, during the conveying and drying process, the water on the magnetic core can be shaken off first, so as to reduce the residual water on the surface of the magnetic core. The shaking method also makes the magnetic core tumble continuously, further improving the drying effect. Combined with the drying component above the conveying assembly, it can achieve efficient drying of the magnetic core and solve the problem of poor drying effect of the magnetic core.

[0014] 2. The central column gap grinding and drying mechanism can slow down the movement speed of the magnetic core on the conveyor belt by setting multiple slow-feed baffles on the surface of the conveyor belt, so that the magnetic core passes under the drying component for a longer time. This allows the magnetic core to be fully dried and reduces the overall length of the conveyor belt, further reducing the volume of the entire mechanism. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the field of electronic component manufacturing, magnetic cores, as essential basic components, are widely used in equipment such as transformers and inductors. With the rapid development of the electronics industry, higher demands are being placed on the performance and production efficiency of magnetic cores. Creating an air gap in the core's central column is one of the key processes in magnetic core production. The accuracy and quality of the air gap directly affect the electromagnetic performance of the magnetic core, and consequently, the stability and reliability of the entire electronic device.

[0025] Due to the technical shortcomings of existing technologies, such as poor drying effect, please refer to... Figures 1-5 This embodiment provides a central column gap grinding and drying mechanism, which can achieve efficient drying of magnetic cores and solve the problem of poor drying effect of magnetic cores. The mechanism includes a housing 1, a conveying component 2 is movably arranged inside the housing 1, two sets of shaking components 3 installed at the bottom of the housing 1 are connected to the bottom of the conveying component 2, and a drying component 4 installed at the top of the housing 1 is provided above the conveying component 2. A discharge port 101 is opened on the side wall of the housing 1, which is horizontally corresponding to the conveying component 2, and a discharge guide plate 5 is installed at the position of the discharge port 101. In use, the ground magnetic core falls onto the conveying component 2, and the conveying component 2 moves to send the magnetic core into the housing 1. During the movement of the magnetic core on the conveying component 2, the shaking components 3 drive the entire conveying component 2 to vibrate in the vertical direction. In this way, during the conveying and drying process, the water on the magnetic core is shaken off to reduce the amount of residual water on the surface of the magnetic core. Then, combined with the drying component 4 above the conveying component 2, the magnetic core is quickly dried during the movement.

[0026] Existing drying mechanisms typically blow hot air directly onto the magnetic core. Since the magnetic core remains stationary on conveyor belt 204 and has significant residual water, the drying effect is poor. For a solution to this problem, please refer to [reference needed]. Figure 4 The vibration component 3 includes a second motor 301 mounted on the side wall of the housing 1. The output shaft of the second motor 301 is fixedly connected to one end of a crankshaft 302 rotatably connected to the bottom of the housing 1. Two connecting rods 303 are hinged to the crankshaft 302, and the ends of the two connecting rods 303 away from the crankshaft 302 are both hinged to a fixed frame 305 through a connecting block 304. The fixed frame 305 is fixed to the bottom of the conveying component 2. The second motor 301 works and drives the crankshaft 302 to rotate. The crankshaft 302 drives the fixed frame 305 to move up and down through the connecting rods 303. The fixed frame 305 drives the entire conveying component 2 to move up and down and create a vibration effect, which can shake the water off the magnetic core to improve the drying efficiency.

[0027] During the drying process of the magnetic core, since the magnetic core moves along with the conveyor belt 204, a sufficiently long drying time is required to ensure that the magnetic core is completely dried. This results in a problem where the length of the conveyor belt 204 is relatively long, leading to a larger overall size of the mechanism. For a solution to this problem, please refer to [reference needed]. Figure 3 The conveying assembly 2 includes a frame 201 movably disposed inside the housing 1. Rollers 202 are rotatably connected to both ends of the frame 201. A motor 203 is mounted on the side wall of the frame 201 and fixedly connected to one of the rollers 202. A conveyor belt 204 is driven between the two rollers 202. Multiple staggered and cross-distributed slow-feeding baffles 205 are fixedly disposed on the inner wall of the frame 201. A discharge baffle 206 is also fixedly disposed inside the frame 201. The motor 203 operates and drives the conveyor belt 204 through the rollers 202 to achieve the purpose of conveying the magnetic core. By setting multiple slow-feeding baffles 205 on the surface of the conveyor belt 204, the moving speed of the magnetic core on the conveyor belt 204 can be slowed down, so that the magnetic core passes under the drying assembly 4 for a longer time. This allows the magnetic core to be fully dried and reduces the overall length of the conveyor belt 204, further reducing the volume of the entire mechanism.

[0028] Furthermore, both the slow-feed baffle 205 and the discharge baffle 206 are inclined; the inclined design allows the magnetic core to gradually move backward as it passes the position of the slow-feed baffle 205, driven by the conveyor belt 204.

[0029] Furthermore, a notch 2011 corresponding to the position of the discharge port 101 is provided on the side wall of the frame 201; when the magnetic core moves to the position of the discharge baffle 206, it will gradually move along the discharge baffle 206 to the position of the notch 2011, and then fall down through the discharge guide plate 5 along the notch 2011 to achieve active discharge.

[0030] Since it is necessary to control the rapid up-and-down movement of the entire conveying assembly 2, in order to ensure the overall stability of the conveying assembly 2, multiple sets of slide rails 208 are installed on the inner wall of the housing 1. Slider 207, which is fixed to the side wall of the frame 201, is slidably set on the slide rails 208. Through the cooperation of the slide rails 208 and the slider 207, the conveying assembly 2 can be made more stable when moving rapidly.

[0031] The existing drying mechanism suffers from uneven hot air distribution, resulting in inconsistent drying effects for the magnetic cores. To address this issue, please refer to... Figure 5 The drying assembly 4 includes an air duct 401 installed at the top of the housing 1. A fan 402 and an electric heating tube 403 are respectively installed at the two ends of the air duct 401, and the electric heating tube 403 is located above the conveying assembly 2. The fan 402 drives air through the electric heating tube 403 to form a hot airflow, which blows from top to bottom toward the magnetic core to ensure uniform heat coverage, improve drying efficiency and consistency. The electric heating tube 403 is located above the conveying assembly 2 and directly heats the surface of the magnetic core, reducing heat loss.

[0032] Furthermore, the distance between the conveying component 2 and the drying component 4 is 15cm-25cm; this distance balances the hot air intensity and the safety distance, ensuring that the hot airflow can effectively act on the surface of the magnetic core while avoiding the risk of overheating or contact.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
