Description

Technical Field

[0001] This application relates to the technical field of magnetic core production equipment, and in particular to a ferrite magnetic core sintering furnace. Background Technology

[0002] Ferrite cores are made of ceramic structures and non-metallic magnetic materials. They are formed by mixing and pressing powdered raw materials to form a blank, which is then sintered at high temperature and polished by subsequent processing equipment to form the final product.

[0003] In the sintering process of green bodies, a belt sintering furnace is typically used to sinter the green bodies. A sintering furnace usually consists of a frame, a conveyor belt mounted on the frame, and the furnace body. The conveyor belt runs through the inside of the furnace body and is heated by an internal heating device. The conveyor belt is used to transport the pressed green bodies, allowing them to automatically enter and exit the furnace body, thus achieving continuous production of pressed green body sintering.

[0004] After being pressed into shape by a molding machine, the pressed blanks are usually temporarily stored in the workpiece storage area or warehouse. During sintering, the workers take them out and place them on the conveyor belt along with the material box. During the storage process, dust easily adheres to the surface of the pressed blanks, affecting the sintering effect. Therefore, before the pressed blanks enter the furnace, the workers usually use an air gun to blow clean the surface of the pressed blanks.

[0005] Although the air gun cleaning method is relatively simple, it can be quite labor-intensive for workers during long-term continuous operation, and the cleaning process may generate dust, which is detrimental to the health of the workers. Utility Model Content

[0006] In order to reduce the workload of workers and reduce dust generation, this application provides a ferrite core sintering furnace.

[0007] The ferrite core sintering furnace provided in this application adopts the following technical solution: A ferrite core sintering furnace includes a sintering furnace body. A purging assembly is arranged on the sintering furnace body near its own feed inlet. The purging assembly includes a purging head and a dust cover. The dust cover is hollow inside. The purging head is arranged inside the dust cover. The dust cover is provided with a clearance hole. When the workpiece is sintered, it passes through the clearance hole and then enters the sintering furnace body. The purging head is connected to a blowing device, and the purging head is provided with a nozzle.

[0008] By adopting the above technical solution, during the sintering process, the worker places the workpiece tray on the conveyor belt of the sintering equipment, and the conveyor belt carries the workpiece tray through the dust cover. As the workpiece passes through the dust cover, the blowing head sprays airflow to clean the surface of the workpiece, thereby achieving automatic cleaning of the workpiece, reducing the workload of the workers, and at the same time, the dust cover prevents the spread of dust and reduces the generation of dust.

[0009] Optionally, a ventilation duct is provided on the dust cover, and the end of the ventilation duct away from the dust cover is connected to an exhaust device.

[0010] By adopting the above technical solution, the gas inside the dust cover is extracted by the ventilation equipment, so that the inside of the dust cover is in a negative pressure state, which reduces the occurrence of dust spreading from the dust cover to the outside of the dust cover.

[0011] Optionally, a baffle is provided at the clearance hole. The baffle is a flexible sheet structure used to seal the clearance hole.

[0012] By adopting the above technical solution, the obstruction hole is sealed with a baffle curtain, thereby preventing dust from spreading through the obstruction hole. Simultaneously, due to the flexibility of the baffle curtain itself, it can automatically avoid the movement of the workpiece during transportation.

[0013] Optionally, the curtain is formed by arranging multiple flexible strips along its own width.

[0014] By adopting the above technical solution, the curtain is composed of multiple flexible strips. During the movement of the workpiece, the flexible strips that are in contact with the workpiece avoid the workpiece, while the flexible strips in other positions can stably block the avoidance holes, thereby improving the stability of the blockage of the avoidance holes.

[0015] Optionally, a connecting rod is provided on the side of the curtain away from the ground, and an installation groove is provided on the dust cover corresponding to the connecting rod, and the connecting rod is inserted into the installation groove in the horizontal direction.

[0016] By adopting the above technical solution, the connecting rod is inserted into the mounting groove, and the mounting groove limits the vertical displacement of the connecting rod, thereby realizing the installation of the curtain.

[0017] Optionally, the dust cover is provided with a limiting component, the limiting component including a baffle that is slidably connected to the dust cover in the vertical direction, and a retaining groove is provided on the connecting rod at the position corresponding to the baffle, so that sliding the baffle can allow one side of it to be inserted into the retaining groove.

[0018] By adopting the above technical solution, the sliding baffle is inserted into the baffle groove, thereby limiting the horizontal displacement of the connecting rod. In conjunction with the mounting groove, it can limit the displacement of the connecting rod in multiple directions, thereby improving the stability of the curtain after installation.

[0019] Optionally, the limiting component further includes an elastic element for applying a force to the baffle to move it toward the connecting rod.

[0020] By adopting the above technical solution, the baffle is stably inserted into the retaining groove through the elastic element, thereby improving the stability of the baffle in limiting the connecting rod. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a ferrite core sintering furnace.

[0028] Reference Figure 1 and Figure 2A ferrite core sintering furnace includes a furnace body 1 and a purging assembly 2 disposed at one end of the furnace. The sintering furnace mainly includes a furnace body and a conveyor belt running through the furnace body. The furnace body has a feed inlet and a discharge outlet at its two ends, respectively. The purging assembly 2 is disposed at the end of the furnace body near its feed inlet. The purging assembly 2 includes a purging head 21 and a dust cover 22. The dust cover 22 is hollow inside and has an opening on the side near the conveyor belt. The purging head 21 is disposed inside the dust cover 22, and is hollow inside with nozzles on its sidewalls. The purging head 21 is connected to an external blowing device (not shown in the figure), allowing gas to be ejected from the nozzles. An obstacle hole 23 is provided through the dust cover 22 along the conveyor belt's transport direction to allow workpieces (in this embodiment, ferrite cores) to pass through. During furnace operation, the operator places a workpiece frame on the conveyor belt, which then carries the workpiece frame (a material frame used to temporarily store ferrite cores) through the dust cover 22 and the furnace body. When the workpiece passes through the dust cover 22, the blowing head 21 inside the dust cover 22 sprays gas to impact the workpiece, automatically blowing it away and reducing the workload of the workers. At the same time, the dust cover 22 blocks the spread of dust and reduces the generation of dust.

[0029] Reference Figure 1 and Figure 2 The top of the dust cover 22 is connected to a ventilation duct 3. One end of the ventilation duct 3 is connected to the inside of the dust cover 22, and the other end is connected to an external exhaust device to facilitate the discharge and collection of dust inside the dust cover 22, while maintaining the pressure balance inside and outside the dust cover 22. Of course, the power of the exhaust device can also be adjusted to create a negative pressure inside the dust cover 22 to further improve the dustproof effect.

[0030] Reference Figure 1 and Figure 2 The nozzle of the blowing head 21 has a flat structure, with its length direction perpendicular to the conveyor belt's conveying direction, allowing the nozzle to thoroughly and effectively blow away the workpiece. A sealing component 6 is installed at the location of the clearance hole 23 of the dust cover 22. The sealing component 6 includes a curtain 61, which comprises multiple flexible strips 62 arranged along the width of the conveyor belt to form a sheet-like curtain 61. As the workpiece moves along the conveyor belt, the flexible curtain 61 automatically makes way for the workpiece's movement, allowing it to pass smoothly through the dust cover 22. Simultaneously, due to the flexible structure of the curtain 61, after detaching from the workpiece, it automatically droops under its own weight to seal the clearance hole 23, further improving the dustproof effect.

[0031] Reference Figure 3 and Figure 4A connecting rod 4 is provided on the side of the curtain 61 away from the ground, and a slot 41 is provided on the side of the connecting rod 4 closest to the ground. The flexible strip 62 is inserted into the slot 41. A mounting groove 42 is provided on the side wall of the dust cover 22 corresponding to the position of the connecting rod 4. The connecting rod 4 is inserted into the mounting groove 42 in a horizontal direction to realize the installation between the curtain 61 and the dust cover 22. A locking screw 43 is provided on the connecting rod 4 corresponding to the position of the flexible strip 62. The locking screw 43 communicates with the inside of the slot 41. By rotating the locking screw 43, its end is pressed against the flexible strip 62, realizing the detachable connection between the flexible strip 62 and the connecting rod 4, so as to facilitate the replacement of the flexible strip 62.

[0032] Reference Figure 3 and Figure 4 A limiting component 5 is provided on the dust cover 22 at the position corresponding to the connecting rod 4. The limiting component 5 includes a baffle 51 that is slidably connected to the dust cover 22 in the vertical direction. A retaining groove 52 is opened on the side wall of the connecting rod 4 facing away from the ground, corresponding to the baffle 51. Sliding the baffle 51 allows the side of the baffle 51 closest to the ground to be inserted into the retaining groove 52. The baffle 51, in conjunction with the mounting groove 42, limits the displacement of the connecting rod 4 in the vertical and horizontal directions, improving the stability of the connecting rod 4 after installation.

[0033] Reference Figure 3 and Figure 4 The limiting component 5 also includes an elastic element 53, which applies a force to the baffle 51 to move it closer to the connecting rod 4. In this embodiment, the elastic element 53 is a spring, with one end fixed to the dust cover 22 and the other end abutting against the baffle 51 and in a compressed state. Under the action of the elastic element 53, the baffle 51 can maintain a force moving closer to the connecting rod 4, thereby further improving the stability of the connecting rod 4 after installation.

[0034] Reference Figure 3 and Figure 4 The limiting component 5 also includes a pull plate 54, which is horizontally arranged. One side of the pull plate 54 is welded to the baffle 51, and the other side extends away from the baffle 51, so that the operator can apply force to the baffle 51 and facilitate the disassembly and installation of the connecting rod 4.

[0035] The implementation principle of a ferrite core sintering furnace according to an embodiment of this application is as follows: the surface of the workpiece is automatically swept by the blowing head 21 inside the dust cover 22, and the dust cover 22 blocks the spread of dust. This reduces the workload of workers and the generation of dust.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
