Description

Technical Field

[0001] This utility model relates to the field of magnetic core production technology, and in particular to a magnetic core drying oven and a magnetic core insulation layer spraying production line. Background Technology

[0002] Magnetic cores, as important electronic components, are widely used in electronic devices such as transformers and inductors. The drying process is one of the key steps in the production of magnetic cores. Preheating and drying curing are required before and after the coating of the magnetic core's insulating layer to ensure uniform curing of the coating and the insulation performance of the magnetic core.

[0003] Currently, there are two main types of common magnetic core drying ovens: trolley ovens and chain-driven drying lines. Referring to a drying device for magnetic core processing (CN217900316U), the trolley oven is suitable for drying and curing large batches of workpieces, offering good temperature uniformity and a reliable control system. However, the trolley oven uses a closed drying system, requiring the magnetic cores to be moved after each drying cycle, increasing labor intensity and production costs. Referring to a toroidal magnetic core insulation layer spraying production line and method (CN115502017B), the chain-driven drying line is suitable for continuous production and can automate workpiece transport. However, its drying chamber is large, and temperature control is difficult, especially in the space below the heating components, which is prone to uneven drying.

[0004] With the expansion of magnetic core production scale and the improvement of quality requirements, there is an urgent need in the market for a drying oven that can achieve continuous production and ensure drying effect. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic core insulation layer spraying production line that can achieve continuous production and ensure drying effect, thereby solving the problems of low drying efficiency, high energy consumption and poor temperature uniformity in the prior art, and improving production efficiency and product quality.

[0006] In a first aspect, this utility model provides a magnetic core drying box, comprising: The heating chamber is provided with a heating cavity, a feed inlet and a discharge outlet, wherein the feed inlet and the discharge outlet are respectively located at opposite ends of the heating cavity; A heating assembly is disposed above the heating cavity, and the heating assembly is used to heat the heating cavity; A first heat insulation plate and a second heat insulation plate are disposed below the heating cavity, and a material gap is provided between the first heat insulation plate and the second heat insulation plate. The material gap connects the feed port and the discharge port so that the support platform for carrying the magnetic core can pass between the feed port and the discharge port.

[0007] The magnetic core drying oven provided by this invention, by incorporating a first and second heat insulation plate, prevents heat loss downwards, reduces ineffective heat dissipation, and significantly improves temperature uniformity and thermal efficiency within the heating cavity. Simultaneously, the support platform moves within the material gap between the first and second heat insulation plates. This design not only enables continuous drying of the magnetic core but also allows the support platform to seal most of the material gap during movement, further reducing heat loss through the gap. Furthermore, the heat insulation plate design protects the material handling mechanism beneath the support platform, avoiding the problem of traditional chain drive mechanisms being entirely located inside the heating chamber and easily damaged by high temperatures. The magnetic core drying oven of this invention not only improves drying efficiency and temperature uniformity but also significantly reduces energy consumption.

[0008] Furthermore, the first heat insulation plate has a first heat insulation cavity, and the second heat insulation plate has a second heat insulation cavity.

[0009] By adopting the above technical solution, a first heat insulation cavity and a second heat insulation cavity are respectively set in the first heat insulation plate and the second heat insulation plate, which increases the heat transfer path and resistance, making it more difficult for heat to be lost to the external environment through the heat insulation plate, and further reducing heat leakage.

[0010] Furthermore, both the first heat insulation board and the second heat insulation board include a first L-shaped board and a second L-shaped board spliced ​​together, and the first L-shaped board and the second L-shaped board surround each other to form the first heat insulation cavity and the second heat insulation cavity.

[0011] By employing the above technical solution, a heat insulation cavity is formed by splicing together a first L-shaped plate and a second L-shaped plate. This structural design improves the overall stability of the heat insulation board. The shape of the L-shaped plate makes the heat insulation board more robust during splicing, enabling it to withstand greater loads and enhancing its load-bearing capacity.

[0012] Furthermore, the first L-shaped plate and the second L-shaped plate are provided with first cover plates at their opposite ends. The first cover plate on the first heat insulation plate is used to close the first heat insulation cavity; the first cover plate on the second heat insulation plate is used to close the second heat insulation cavity.

[0013] By employing the above technical solution, and by setting first cover plates at both ends of the first L-shaped plate and the second L-shaped plate, the heat insulation cavity can be effectively sealed. This design further reduces heat loss from the heat insulation cavity to the outside, thus improving the heat insulation effect.

[0014] Furthermore, it also includes a third heat insulation plate and a fourth heat insulation plate, which are respectively disposed on opposite sides of the heating cavity in the horizontal direction. The third heat insulation plate and the heating box form a third heat insulation cavity, and the fourth heat insulation plate and the heating box form a fourth heat insulation cavity.

[0015] By employing the above technical solution, a third and fourth heat insulation plate are respectively installed on opposite sides of the heating cavity in the horizontal direction, forming a third and a fourth heat insulation cavity, thus achieving all-round heat insulation of the heating cavity. This design not only reduces heat transfer downwards but also effectively reduces heat transfer to both sides, further reducing heat loss. The presence of the heat insulation cavity reduces temperature fluctuations, making the temperature inside the drying oven more stable, thereby improving the reliability and consistency of the drying process.

[0016] Furthermore, a second cover plate is provided between the third heat insulation plate and the heating box, the second cover plate being used to seal the third heat insulation cavity; a third cover plate is also provided between the fourth heat insulation plate and the heating box, the third cover plate being used to seal the fourth heat insulation cavity.

[0017] By employing the above technical solution, and by installing a second cover plate between the third insulation plate and the heating chamber, and a third cover plate between the fourth insulation plate and the heating chamber, the sealing performance of the insulation cavity is further enhanced. This design effectively prevents heat loss from the openings of the insulation cavity, thus improving the insulation effect.

[0018] Furthermore, it also includes a blower, which is mounted on the heating box and can blow the air heated by the heating components into the heating cavity.

[0019] By employing the above technical solution, a blower is installed above the heating chamber to blow the air heated by the heating components into the heating cavity, promoting the circulation of hot air within the cavity. This forced convection method allows heat to be distributed more evenly throughout the drying chamber, significantly reducing the temperature gradient within the heating cavity and ensuring uniform heating of the magnetic core during the drying process, thus avoiding problems such as localized overheating or uneven drying.

[0020] Furthermore, the heating assembly includes a plurality of heating wires, which are spaced apart above the heating cavity, and all of the heating wires extend from the feed inlet toward the discharge outlet.

[0021] By employing the above technical solution, the heating component uses multiple heating wires arranged at intervals, extending from the feed inlet towards the discharge outlet, which allows for a more even distribution of heat throughout the heating cavity. This layout avoids the problems of localized overheating or uneven drying, further improving the drying quality.

[0022] Secondly, this utility model provides a magnetic core insulation layer spraying production line, comprising: Multiple magnetic core drying boxes, wherein the inlet and outlet of the multiple heating boxes are connected end to end; The support platform is used to support the magnetic core; A material handling mechanism is located below the support platform, and the material handling mechanism is capable of driving the support platform to move between the multiple heating cavities.

[0023] By employing the above technical solution, multiple heating chambers are connected in series to form a continuous drying production line, effectively reducing heat loss at the inlet and outlet. Each heating chamber can be independently temperature-controlled, minimizing the temperature gradient between the inlet and outlet, thereby reducing the intake of cold air and heat loss. Furthermore, each heating chamber can be independently controlled for both temperature and time, allowing for optimization based on the drying requirements of different stages, further improving drying quality.

[0024] Furthermore, the material handling mechanism includes drive wheels, drive belts, and annular slide rails. There are multiple drive wheels, and the drive belts are sleeved on the multiple drive wheels. The support platform is movably mounted on the annular slide rails, and the support platform is fixedly connected to the drive belts. The multiple drive wheels can drive the support platform to move on the annular slide rails via the drive belts.

[0025] As can be seen from the above, the magnetic core drying oven provided by this utility model, by setting up a first heat insulation plate and a second heat insulation plate, avoids heat loss downwards, reduces ineffective heat dissipation, and significantly improves the temperature uniformity and thermal efficiency within the heating cavity. Simultaneously, the support platform moves within the material gap between the first and second heat insulation plates. This design not only enables continuous drying of the magnetic core, but also allows the support platform to close most of the material gap during movement, further reducing heat loss through the gap. Furthermore, the heat insulation plate design protects the material handling mechanism below the support platform, avoiding the problem of traditional chain drive mechanisms being entirely located inside the heating chamber and easily damaged by high temperatures. The magnetic core drying oven of this utility model not only improves drying efficiency and temperature uniformity but also significantly reduces energy consumption.
