Description

Technical Field

[0001] The invention relates to the technical field of grinders, in particular to a dustproof grinder for processing hardware parts. Background Art

[0002] In the hardware parts processing industry, grinders are key processing equipment, and their performance and efficiency directly affect product quality and production efficiency. However, traditional grinders have significant dust prevention problems during use, which not only affects the cleanliness of the processing environment, but also may pose a threat to the health of operators.

[0003] During the processing of hardware parts, grinding operations will generate a large amount of dust. Traditional grinding machines often lack effective dust collection and treatment mechanisms, resulting in the free diffusion of dust in the processing area. This not only pollutes the processing environment, but may also pollute surrounding equipment and parts, affecting the quality and precision of the product. The spread of dust may also cause damage to the respiratory system of operators. Operators may face the risk of respiratory diseases if exposed to high concentrations of dust for a long time. In traditional grinding machine dust prevention devices, the filter is a key filter element. However, the filter is prone to clogging during long-term use and needs to be replaced or cleaned regularly. However, existing grinding machines often have problems with filter replacement and maintenance difficulties, which not only increases the labor intensity of operators, but also may affect the normal operation of dust prevention devices. Difficulties in filter replacement and maintenance may also lead to untimely filter replacement, further exacerbating the problem of dust diffusion and low collection efficiency. Summary of the invention

[0013] Step 1. First, place the hardware parts to be processed on the placement table, start cylinder 1, push the lifting seat down to the appropriate position through the push rod, so that the grinding head is close to the workpiece, and the frequency conversion motor drives the threaded rotating rod to rotate, so that the threaded sleeve drives the grinding head to move left and right, so that the grinding head is in the appropriate position. During the grinding process, the dust generated is captured by the dust suction pipe.

[0014] Step 2: Under the action of the induced draft fan, the dust enters the dust suction pipe through the dust inlet pipe, and then falls into the dust collecting box through the dust exhaust pipe. At the same time, the gas containing dust continues to flow and enters the filter box. Inside the filter box, the gas is filtered by filter mesh 1 and filter mesh 2 in turn to achieve further separation of the dust. The filtered gas is discharged through the exhaust pipe. The gas first enters the gas collecting box and then is discharged through the gas outlet net to reduce pollution to the environment.

[0015] Step three, when filter 1 and filter 2 are seriously clogged, you can easily replace or clean the filter by loosening fixing bolt 1 and fixing bolt 2, and removing mounting plate 2 from the fixing groove. The top plate is snap-connected to the top of the filter box through the snap block, which is convenient for disassembly and installation of the filter assembly; the position of the support sleeve and the connecting seat can be adjusted by the push of cylinder 2, and then the height and angle of the dust suction pipe can be adjusted to meet the processing requirements of parts of different sizes. After the adjustment is completed, fix the L-shaped plate and the vertical plate with fixing bolt 1 to ensure the stability of the dust suction pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The dustproof grinder for hardware parts processing has a shell set on the top of the base, and configures components such as a dust suction pipe, a chassis, an induced draft fan and a filter box inside the shell to construct an efficient dust collection and treatment structure. During the grinding process, the dust is quickly captured by the dust suction pipe, and under the strong action of the induced draft fan, it enters the filter box for filtration through the dust inlet pipe and the dust suction pipe. This mechanism effectively avoids the free diffusion of dust in the processing area and significantly improves the cleanliness of the processing environment. The filter box is equipped with a two-stage filtering device, filter screen 1 and filter screen 2, to further separate and purify the dust. This double filtering design not only improves the filtering efficiency, but also extends the service life of the filter screen, reduces the frequency of filter screen replacement, and thus reduces maintenance costs. The filter screen can be quickly installed and removed by installing components such as the first and second mounting plates and the fixing slot. When the filter screen is seriously clogged, the operator can Easily loosen fixing bolt 1 and fixing bolt 2, remove mounting plate 2 from the fixing groove, and complete the replacement or cleaning of the filter. This design greatly simplifies the process of filter replacement and maintenance, and reduces the labor intensity of operators. The height and angle of the dust suction pipe can be flexibly adjusted through components such as cylinder 2, support sleeve and connecting seat. This design enables the dust suction pipe to adapt to the processing needs of hardware parts of different sizes to ensure the effective collection of dust. At the same time, the L-shaped plate and the vertical plate are fixed by fixing bolt 1 to ensure the stability of the dust suction pipe after adjustment. The filtered gas is discharged into the air collecting box through the exhaust pipe and finally discharged through the air outlet net. This design not only reduces dust leakage during gas emission, but also further reduces pollution to the environment. At the same time, the configuration of the air collecting box and the air outlet net also plays a role in buffering and diffusing the gas, avoiding local pollution caused by gas emission.

[0032] A method for using a dustproof grinder for processing hardware parts comprises the following steps:

[0033] Step 1. First, place the hardware parts to be processed on the placement table 3, start the cylinder 5, push the lifting seat 4 down to the appropriate position through the push rod 6, so that the grinding head 10 is close to the workpiece, and the frequency conversion motor 11 drives the threaded rotating rod 7 to rotate, so that the threaded sleeve 8 drives the grinding head 10 to move left and right, so that the grinding head 10 is in a suitable position. During the grinding process, the dust generated is captured by the dust suction pipe 13.

[0036] In summary, the dustproof grinder for processing hardware parts has a shell 2 set on the top of the base 1, and components such as a dust suction pipe 13, a chassis 14, an induced draft fan 15 and a filter box 16 are arranged inside the shell 2, so as to construct an efficient dust collection and treatment structure. During the grinding process, the dust is quickly captured by the dust suction pipe 13, and under the strong action of the induced draft fan 15, the dust enters the filter box 16 through the dust inlet pipe 12 and the dust suction pipe 13 for filtration. This mechanism effectively avoids the free diffusion of dust in the processing area and significantly improves the cleanliness of the processing environment. A two-stage filtering device, filter screen 1 22 and filter screen 23, is arranged inside the filter box 16 to further separate and purify the dust. This double filtering design not only improves the filtering efficiency, but also extends the service life of the filter screen, reduces the frequency of filter screen replacement, and thus reduces the maintenance cost. The filter screen can be quickly installed and removed by components such as the mounting plate 1 20, the mounting plate 21 and the fixing groove 18. When the filter screen is seriously clogged, the operator can The fixing bolts 1 33 and 2 42 can be easily loosened, and the mounting plate 2 21 can be taken out from the fixing groove 18 to complete the replacement or cleaning of the filter. This design greatly simplifies the process of filter replacement and maintenance, and reduces the labor intensity of operators. The height and angle of the dust suction pipe 13 can be flexibly adjusted by components such as the cylinder 2 39, the support sleeve 36 and the connecting seat 37. This design enables the dust suction pipe 13 to adapt to the processing requirements of hardware parts of different sizes to ensure the effective collection of dust. At the same time, the L-shaped plate 29 and the vertical plate 30 are fixed by the fixing bolts 1 33 to ensure the stability of the dust suction pipe 13 after adjustment. The filtered gas is discharged into the air collecting box 26 through the exhaust pipe 25, and finally discharged through the air outlet net 43. This design not only reduces dust leakage during gas emission, but also further reduces pollution to the environment. At the same time, the configuration of the air collecting box 26 and the air outlet net 43 also plays a role in buffering and diffusing the gas, avoiding local pollution caused by gas emission.

7. The dustproof grinding machine for hardware parts processing according to claim 1, characterized in that: A dustproof movable door (44) is movably mounted on the front side of the shell (2), and ventilation nets (45) are fixedly mounted on both sides of the top of the shell (2).

8. The method for using a dustproof grinder for processing hardware parts according to any one of claims 1 to 7, characterized in that: The steps include: Step 1: first, place the hardware parts to be processed on the placement table (3), start the cylinder 1 (5), push the lifting seat (4) down to a suitable position through the push rod (6), so that the grinding head (10) is close to the workpiece, and the frequency conversion motor (11) drives the threaded rotating rod (7) to rotate, so that the threaded sleeve (8) drives the grinding head (10) to move left and right, so that the grinding head (10) is located at a suitable position. During the grinding process, the dust generated is captured by the dust suction pipe (13); Step 2: Under the action of the induced draft fan (15), the dust enters the dust suction pipe (13) through the dust inlet pipe (12), and then falls into the interior of the dust collecting box (27) through the dust exhaust pipe (28). At the same time, the gas containing the dust continues to flow and enters the filter box (16). Inside the filter box (16), the gas is filtered by the filter screen 1 (22) and the filter screen 2 (23) in sequence to achieve further separation of the dust. The filtered gas is discharged through the exhaust pipe (25). The gas first enters the gas collecting box (26) and then is discharged through the gas outlet net (43) to reduce pollution to the environment. Step 3: When the filter screen 1 (22) and the filter screen 2 (23) are seriously blocked, the filter screens can be conveniently replaced or cleaned by loosening the fixing bolts 1 (33) and the fixing bolts 2 (42) and removing the mounting plate 2 (21) from the fixing groove (18). The top plate (19) is snap-fitted to the top of the filter box (16) by the snap-fit ​​block (24), so as to facilitate the removal and installation of the filter screen assembly. The positions of the support sleeve plate (36) and the connecting seat (37) can be adjusted by pushing the cylinder 2 (39), and the height and angle of the dust suction pipe (13) can be adjusted to meet the processing requirements of parts of different sizes. After the adjustment is completed, the L-shaped plate (29) and the vertical plate (30) are fixed by the fixing bolts 1 (33) to ensure the stability of the dust suction pipe (13).
