Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, in particular to a device for removing rust from the surface of mobile phone parts and collecting iron chips. Background Art

[0002] When removing rust from the surface of mobile phone parts, the grinding head can be made of a material with a high hardness, such as diamond abrasive. Driven by a motor, the grinding head rotates at high speed and can remove rust from the surface of mobile phone parts through physical friction. This mechanical grinding effect is more significant for parts with regular shapes and relatively flat surfaces, such as the flat part of the metal casing of a mobile phone.

[0003] During the rust removal process, both metal dust generated by mechanical grinding and volatile substances generated by chemical rust removal will pollute the air. If these harmful substances are not collected and treated in a timely manner, they will cause serious harm to the health of operators, such as respiratory diseases and lung damage. At the same time, metal dust diffused in the air also poses an explosion risk and may cause serious safety accidents under certain concentrations and environmental conditions.

[0004] When using the existing technology, iron filings are collected through a filter. The filter is easily clogged by a large amount of iron filings during the collection process. Especially when the amount of iron filings generated during the rust removal process is large, the filtration speed of the filter will drop rapidly, resulting in poor gas circulation. Once the filter is clogged, the machine needs to be shut down for cleaning or replacement, which will reduce the working efficiency of the device and increase maintenance costs.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 4As shown, a device for removing rust from the surface of mobile phone parts and collecting iron chips includes a grinding chamber 1 and a blocking door 12. A transmission assembly 2 is provided on the grinding chamber 1;

[0033] The transmission assembly 2 includes a lower bin 21, an upper bin 22 is slidably connected to the lower bin 21, a second rotating shaft 28 is rotatably connected to the upper bin 22, a return spring 27 is fixedly connected to the second rotating shaft 28, a placement plate 23 is fixedly connected to the return spring 27, the placement plate 23 is slidably connected in the upper bin 22, an arc-shaped member 25 is fixedly connected to the second rotating shaft 28, a blocking member 26 is provided on the arc-shaped member 25, a motor 31 is fixedly connected in the grinding bin 1, the filter 3 transmission assembly 2 is fixedly connected to the motor 31, a grinding head 33 is fixedly connected to the filter 3 transmission assembly 2, and a fan 34 is provided in the grinding bin 1;

[0034] In the present invention, when the filter 3 is blocked, it will be blown to drive the placement plate 23 to move, and then drive the second rotating shaft 28 to rotate, so that the arc-shaped member 25 drives the blocking member 26 to slide downward on the lower bin 21, blocking the lower bin 21 and the upper bin 22, to prevent large debris from being blown out during the replacement of the filter 3. After the filter 3 is blocked, the filter 3 will move driven by the wind flow, and then drive a series of components to move to a position convenient for replacement. This process does not require stopping the machine to wait for manual inspection of the filter 3 blockage. Compared with the prior art in which the filter 3 needs to be stopped for cleaning or replacement of the filter 3 after it is blocked, it effectively avoids the problem of reduced working efficiency of the device due to blockage of the filter 3.

[0035] Further, such as Figures 1 to 4 As shown, a ventilation pipe 35 is fixedly connected to the grinding chamber 1, and the ventilation pipe 35 is fixedly connected to the lower chamber 21. A fan 34 is fixedly connected to the ventilation pipe 35. By providing the ventilation pipe 35 and the fan 34, when in use, the fan 34 can be started to blow the debris and powder splashed by grinding in the grinding chamber 1 into the lower chamber 21 and the upper chamber 22;

[0036] The filter screen 3 is slidably connected to the sliding opening of the three sliding openings on the upper bin 22, which is away from the blocking member 26. The filter screen 3 is slidably connected to the placement plate 23. An opening is opened on the side of the inner bin and the outer bin near the filter screen 3. By providing the filter screen 3, large debris particles are blocked by the filter screen 3, and small particles are blown out from the inner bin and the outer bin;

[0037] The placement plate 23 is fixedly connected to a sliding block 24, which is slidably connected to a sliding opening opened laterally among the three sliding openings of the upper compartment 22. When in use, the placement plate 23 can be moved by the sliding block 24.

[0038] A third rotating shaft 4 is fixedly connected between the lower warehouse 21 and the upper warehouse 22. The first rotating shaft 11 is rotatably connected to the grinding warehouse 1. The first rotating shaft 11 is fixedly connected to the blocking door 12. By providing the third rotating shaft 4, the third rotating shaft 4 can connect the upper warehouse 22 and the lower warehouse 21.

[0039] The above solution also has the problem that when in use, the arc-shaped member 25 may drive the blocking member 26 to move to the side away from the filter 3, and the blocking member 26 may be broken. Figures 2 to 4 As shown, a connecting rope 29 is fixedly connected to the arc-shaped member 25, and the connecting rope 29 is fixedly connected to the blocking member 26. Three sliding openings are opened on the upper warehouse 22, and the blocking member 26 is slidably connected in the sliding openings on the upper warehouse 22. The setting of the connecting rope 29 ensures that the arc-shaped member 25 will not get stuck when driving the blocking member 26 to slide in the sliding openings on the upper warehouse 22, and the blocking member 26 can only slide up and down in the sliding openings.

[0040] Working principle: Figures 1 to 4 As shown, before use, an air pump is installed on the side of the upper bin 22 away from the filter screen 3, and a filter bag is fixed on the side of the upper bin 22 close to the filter screen 3;

[0041] When in use, the blocking door 12 is opened by external force to rotate on the grinding chamber 1, the metal raw material to be ground is placed in the grinding chamber 1, and the blocking door 12 is closed. Then, the motor 31 is started, and the motor 31 drives the filter 3 transmission assembly 2 to rotate, and then drives the grinding head 33 to rotate, thereby achieving the grinding of the metal raw material;

[0042] During the grinding process, the fan 34 is started, and the fan 34 blows the metal debris in the grinding chamber 1 to the space between the lower chamber 21 and the upper chamber 22. Large debris is blocked by the filter 3, and small debris is blown into the filter bag.

[0043] When the debris on the filter 3 accumulates to a certain extent and the filter 3 is blocked, the blockage on the filter 3 increases and it will be driven by the wind flow to move, so that the placement plate 23 is driven to move. During the movement of the placement plate 23, the second rotating shaft 28 is driven to rotate, so that the second rotating shaft 28 drives the arc-shaped member 25 to move, and the arc-shaped member 25 drives the blocking member 26 to slide on the upper warehouse 22, blocking the lower warehouse 21. At this time, the filter 3 is close to the sliding port on the lower warehouse 21, and can be removed by external force, replaced with a new filter 3, and then the sliding block 24 is moved by external force, so that the placement plate 23 drives the new filter 3 to reset, thereby realizing the collection of debris.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
