Technical Field
[0001] This utility model relates to the field of brake disc casting technology, specifically to an automatic feeding device for an electric furnace for brake disc casting. Background Technology
[0002] In a car's braking system, the brake disc plays a crucial role. It is a key component connecting the wheel hub and the brake caliper, converting the vehicle's kinetic energy into heat energy through friction to achieve deceleration or stopping. During the brake disc casting process, iron sand serves as the core molding material, and its quality directly affects the finished product's quality and performance. The iron sand has an iron content exceeding 98%, ensuring high strength and durability of the casting. The extremely low internal impurity content of the iron sand reduces casting defects. The iron sand is melted at high temperatures in an electric furnace to shape it into the specified brake disc design.
[0003] When conveying iron sand into the electric furnace, a screw feeding method is usually used. The motor drives the threaded rod inside the outer shell to rotate, so that the iron sand inside the threaded rod is conveyed as the threaded rod rotates.
[0004] When iron sand is conveyed to the feed inlet of the screw conveyor, dust and impurities are present in the iron sand, which will cause dust to be generated during the conveying process. At this time, the personnel conveying the iron sand will breathe in the dust floating in the air, which will affect their health. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic feeding device for a brake disc casting electric furnace, in order to solve the problem mentioned in the background art that when iron sand is transported to the feed inlet of the screw feeder, dust and impurities are present in the iron sand, which will cause dust to be generated during the transportation process. At this time, the personnel transporting the iron sand will breathe in the dust floating in the air, which will affect their health.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a brake disc casting electric furnace, comprising: a spiral feeding assembly, a vacuum mechanism, a separation and cleaning mechanism, and a collection mechanism.

The separation and cleaning mechanism includes a cylinder located on the outer wall of the inlet of the spiral feeding assembly, a fixed block located at the output end of the cylinder, a guide rod horizontally slidably connected inside the fixed block, a fixed plate welded to the guide rod, a cleaning block welded to the outer wall of the fixed plate, and a spring sleeved on the guide rod. The collection mechanism is located inside the connecting pipe.
[0007] By adopting the above technical solution, it is possible to clean and collect the dust that is raised.
[0008] Preferably, a rectangular hole is provided at the bottom of the connecting pipe.

[0032] 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.
[0033] The following is in conjunction with the appendix Figure 1-5 The embodiments of this utility model will be described in further detail.
[0034] Example 1:
[0035] Please see Figures 1-5 This embodiment provides a technical solution: an automatic feeding device for a brake disc casting electric furnace, comprising: a spiral feeding assembly 1, an air extraction mechanism 2, a separation and cleaning mechanism 3, and a collection mechanism 4;
[0036] The spiral feeding assembly 1 consists of a pipe with an inlet and an outlet and a threaded rod connected internally by a motor. The inlet of the spiral feeding assembly 1 has a through hole. The above is the prior art and will not be described in detail below.
[0037] The suction mechanism 2 is installed on the outer wall of the through hole of the spiral feeding assembly 1. The suction mechanism 2 includes a connecting pipe 201 with one end installed on the outer wall of the through hole of the spiral feeding assembly 1. A rectangular hole is opened at the bottom of the connecting pipe 201. The vacuum cleaner body 202 is connected to the other end of the connecting pipe 201 and the filter screen 203 is installed inside the connecting pipe 201.
[0038] The separation and cleaning mechanism 3 is located inside the feed inlet of the screw feeding assembly 1. The separation and cleaning mechanism 3 includes a cylinder 301 located on the outer wall of the feed inlet of the screw feeding assembly 1, a fixed block 302 located on the output end of the cylinder 301, a guide rod 303 horizontally slidably connected inside the fixed block 302, a fixed plate 304 welded to the guide rod 303, a cleaning block 305 welded to the outer wall of the fixed plate 304, the cleaning block 305 located at one end of the filter screen 203 is hemispherical in shape, and the size of the filter screen 203 is adapted to the inner diameter of the mesh of the filter screen 203, and a spring 306 sleeved on the guide rod 303. The collection mechanism 4 is located inside the connecting pipe 201.
[0039] Iron sand is conveyed to the feed inlet of the screw conveyor assembly 1. At this time, the motor drives the threaded rod inside the housing to rotate, so that the iron sand inside the threaded rod is conveyed with the rotation of the threaded rod. When the iron sand is conveyed to the feed inlet of the screw conveyor assembly 1 and dust is generated, the exhaust mechanism 2 is activated to quickly clean and absorb the dust. When the iron sand accumulates and causes blockage of the exhaust mechanism 2, the separation and cleaning mechanism 3 can clean the blockage of iron sand, and the collection mechanism can collect the iron sand.
[0040] When dust is generated, the vacuum cleaner body 202 is activated. The vacuum cleaner body 202, connected to the connecting pipe 201, collects the dust. The filter screen 203 isolates iron filings from dust. When the mesh of the filter screen 203 is blocked by iron filings, the cylinder 301 is activated, causing the fixed block 302 to move vertically. When the fixed block 302 moves to the outside of the filter screen 203, the spring 306 on the outside of the guide rod 303 pushes the cleaning block 305 on the fixed plate 304, causing the hemispherical end of the cleaning block 305 to clear the blockage in the mesh of the filter screen 203.
[0041] Example 2:
[0042] Please see Figure 5 This embodiment provides a technical solution: an automatic feeding device for a brake disc casting electric furnace, comprising: a collection box 401, a baffle 402, and a handle 403;
[0043] The collection mechanism 4 includes a collection box 401 that is horizontally slidably connected inside the rectangular hole of the connecting pipe 201. A sealing strip is pasted on the outer wall of the collection box 401 in contact with the inner wall of the rectangular hole of the connecting pipe 201. A baffle 402 is obliquely welded to the inner wall of the rectangular hole of the connecting pipe 201. The baffle 402 has holes for gas flow. A handle 403 is welded to the outer wall of the collection box 401.
[0044] When the iron filings inside the mesh of the filter screen 203 are cleaned by the cleaning block 305 and fall into the interior of the connecting pipe 201, the interior of the connecting pipe 201 is subjected to the suction generated by the vacuum cleaner body 202 during operation, thereby moving the iron filings inside the connecting pipe 201. At this time, the connecting pipe 201 is equipped with a baffle 402 that only provides dust and air circulation. When the iron filings come into contact with the baffle 402, they fall into the collection box 401 for collection due to gravity. Subsequently, the collection box 401 can be removed from the rectangular hole of the connecting pipe 201 by holding the handle 403.
[0045] The implementation principle of the automatic feeding device for a brake disc casting electric furnace of this utility model is as follows:
[0046] First, the iron sand is conveyed to the feed inlet of the screw conveyor assembly 1. At this time, the motor drives the threaded rod inside the shell to rotate, so that the iron sand inside the threaded rod is conveyed with the rotation of the threaded rod. When the iron sand is conveyed to the feed inlet of the screw conveyor assembly 1 and dust is generated, the exhaust mechanism 2 is started to quickly clean and absorb the dust. When the iron sand accumulates and causes blockage of the exhaust mechanism 2, the separation and cleaning mechanism 3 can clean the blockage of iron sand, and then the collection mechanism can collect the iron sand.
[0047] Secondly, when dust is generated, the vacuum cleaner body 202 is activated. The vacuum cleaner body 202, connected to the connecting pipe 201, collects the dust. The filter screen 203 isolates iron filings from dust. When the mesh of the filter screen 203 is blocked by iron filings, the cylinder 301 is activated, causing the fixed block 302 to move vertically. When the fixed block 302 moves to the outside of the filter screen 203, the spring 306 on the outside of the guide rod 303 pushes the cleaning block 305 on the fixed plate 304, causing the hemispherical end of the cleaning block 305 to clear the blockage in the mesh of the filter screen 203.
[0048] Finally, when the iron filings inside the filter screen 203 are cleaned by the cleaning block 305 and fall into the connecting tube 201, the connecting tube 201 is subjected to the suction generated by the vacuum cleaner body 202 during operation, which moves the iron filings inside the connecting tube 201. At this time, the connecting tube 201 is equipped with a baffle 402 that only provides dust and air circulation. When the iron filings come into contact with the baffle 402, they fall into the collection box 401 for collection due to gravity. Subsequently, the collection box 401 can be removed from the rectangular hole of the connecting tube 201 by holding the handle 403.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
