Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a surface polishing device for metal product processing. Background Art

[0002] Surface polishing of metal products is a processing technology that removes the rough parts of the metal surface by physical or chemical methods to make the surface smooth and flat. It is also called metal surface leveling technology.

[0003] After searching, the patent publication number CN221248289U discloses a metal surface polishing device. Although the device is used by placing the workpiece on the clamping plate and holding the rubber handle, then starting the main motor, the main motor drives the grinding wheel to rotate, and then holding the clamping plate and the rubber handle, the position of the workpiece is adjusted by the clamping plate, the slider and the sliding plate so that it can be polished into a specified shape, the device is unable to collect and process the dust generated during the grinding process. The dust generated during the metal grinding process often contains fine particles such as metal particles and grinding wheel abrasives. These particles are suspended in the air and may cause respiratory diseases such as pneumoconiosis after workers inhale them for a long time. In addition, some metal dusts (such as chromium, nickel, etc.) are toxic. Long-term exposure to these dust environments will seriously threaten the health of workers. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a surface polishing device for metal product processing, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A surface polishing device for processing metal products comprises a bottom plate, a base is mounted on the bottom plate, a second motor is mounted on the base, and polishing heads are mounted at both ends of the second motor;

[0007] The second motor is provided with a shield at the grinding head, a connecting pipe is provided on the shield, a tee is provided at one end of the connecting pipe facing away from the shield, and the tee is provided on the dust collecting box;

[0008] The dust collecting box is provided with a top cover, the three-way pipe is located on the top cover of the dust collecting box, a fan is installed on one side of the three-way pipe on the top cover, a first motor is installed on the fan, a partition is provided in the dust collecting box, and the dust collecting box is separated into a first accommodating chamber and a second accommodating chamber by the partition, and the three-way pipe and the fan correspond to the positions of the second accommodating chamber and the first accommodating chamber respectively.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, an end cover is installed on the end of the shield facing away from the second motor, and the end cover is locked and fixed to the shield by a lock.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] During the polishing process, metal chips and dust may be thrown by the rotating grinding head. The tight connection between the guard and end cap effectively prevents the spread of these flying particles, reducing potential hazards to operators and the surrounding environment. The guard and end cap design also protects the secondary motor, preventing metal chips and dust from entering the motor, which could affect normal operation or cause safety issues such as short circuits. The latch design makes the end cap easy to remove and install. When cleaning the interior of the guard or replacing worn parts, the end cap can be quickly opened for operation, improving equipment maintenance efficiency.

[0013] Furthermore, the three-way pipe and the fan are symmetrically distributed on the top cover, and the partition is located on the center line of the dust box.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The symmetrical placement of the three-way pipe and fan on the top cover ensures a more even flow within the dust box, reducing airflow turbulence and eddy currents, thereby improving dust collection efficiency. The optimized airflow path helps reduce fan resistance during operation, lowering energy consumption and improving the equipment's energy efficiency.

[0016] Furthermore, a notch is provided at the bottom end of the partition, and the first accommodating cavity and the second accommodating cavity are communicated through the notch at the bottom end of the partition.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] When the negative pressure within the second chamber draws the liquid and dust mixture toward the notch, air overflows through the notch into the first chamber. This design ensures that the dust drawn in with the air is completely absorbed by the liquid within the dust box, preventing secondary dust dispersion and contamination. The notch allows the dust and liquid mixture to flow smoothly from the second chamber into the first, further improving dust removal efficiency and ensuring a clean working environment. The notch helps balance the pressure difference between the two chambers, reducing vibration and noise caused by uneven pressure and enhancing device stability.

[0019] Furthermore, the dust collecting box is filled with liquid, and the liquid level is located five centimeters above the notch.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The liquid level is located five centimeters above the notch, forming an effective dust interception zone. When dust is drawn into the dust box along with the air, it first comes into contact with the liquid and is adsorbed, thus preventing the dust from being dispersed again. This design ensures that the dust is fully adsorbed by the liquid before reaching the notch, greatly improving dust removal efficiency. At the same time, the presence of the liquid also helps reduce dust pollution to the air and improve the working environment. Using liquid to adsorb dust not only reduces dust pollution to the environment, but also avoids the secondary pollution that may occur with traditional dust removal methods. At the same time, this design also helps to reduce the energy consumption and operating costs of the equipment.

[0022] Furthermore, a filter is installed in the first accommodating cavity, and the filter is located above the liquid level in the dust box.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The filter, positioned above the liquid surface, further removes fine dust particles remaining in the air after being adsorbed by the liquid. This design ensures cleaner air discharged into the atmosphere and reduces environmental pollution from dust. The dual effects of initial adsorption by the liquid and fine filtration by the filter significantly improve dust removal efficiency. This allows for near-complete collection and disposal of dust generated during the polishing process, maintaining a clean working environment. The filter prevents dust from directly entering critical components such as the fan, reducing the risk of wear and clogging caused by dust, thereby extending the fan's service life.

[0025] Furthermore, there are two grinding heads in total, and the two grinding heads are symmetrically distributed on both sides of the second motor.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The two grinding heads are symmetrically positioned on either side of the second motor, allowing them to polish both sides of the workpiece simultaneously, significantly improving polishing efficiency. This double-sided polishing method reduces polishing time and increases production speed. Because the two grinding heads are symmetrically positioned, they apply consistent pressure and speed to both sides of the workpiece, resulting in a uniform polishing effect. This helps reduce surface irregularities and improves polishing quality. The symmetrical distribution of the grinding heads creates a balanced force distribution structure, reducing stress and deformation caused by uneven force. This helps improve the stability and durability of the equipment, extending its service life.

[0028] The utility model provides a surface polishing device for metal product processing.

[0029] Beneficial effects:

[0030] Through the designed fan system and dust collection box, the equipment can effectively absorb the dust generated during the grinding process into the dust collection box, greatly reducing the dust pollution in the working environment, improving the cleanliness of the working environment and protecting the health of operators.

[0031] Liquid (such as water or a specially treated liquid) filled in the dust box effectively absorbs the inhaled dust and prevents it from being re-dispersed into the air. Especially when designed with liquid level control and overflow notches, this ensures that the dust is fully absorbed, further improving the dust removal effect.

[0032] The dust box is divided into a primary and secondary chambers by a partition. This design allows air to be filtered under negative pressure, removing dust and liquids, before passing through the filter screen and entering the fan. This effectively prevents direct dust damage to the fan and extends the life of the equipment. The filter screen installed in the primary chamber removes fine dust particles that enter with the air, ensuring pure air entering the fan. This not only protects the fan's normal operation but also prevents potential secondary contamination. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 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.

[0041] See also Figures 1 to 3 As shown, the embodiment provided by the utility model:

[0042] Example 1

[0043] A surface polishing device for processing metal products includes a base plate 3, a base 4 is mounted on the base plate 3, a second motor 5 is mounted on the base 4, and grinding heads 6 are mounted on both ends of the second motor 5. There are two grinding heads 6 in total, and the two grinding heads 6 are symmetrically distributed on both sides of the second motor 5. The two grinding heads 6 are symmetrically distributed on both sides of the second motor 5, and can polish both sides of the workpiece at the same time, which significantly improves the polishing efficiency. This double-sided polishing method reduces polishing time and increases production speed. Since the two grinding heads 6 are symmetrically distributed, the pressure and speed they apply to both sides of the workpiece can be kept consistent, thereby achieving a uniform polishing effect. This helps to reduce the unevenness of the workpiece surface and improve the polishing quality. The symmetrically distributed grinding heads 6 help to form a balanced force structure and reduce the stress and deformation caused by uneven force. This helps to improve the stability and durability of the equipment and extend the service life of the equipment. The second motor 5 is installed with a shield 602 at the grinding head 6. The end of the shield 602 facing away from the second motor 5 is installed with an end cover 601, and the end cover 601 is locked and fixed to the shield 602 by a lock. During the polishing process, due to the high-speed rotation of the grinding head 6, metal debris and dust are very likely to splash out. However, the close combination of the shield 602 and the end cover 601 can effectively prevent the spread of these splashes, thereby reducing the potential harm to the operator and the surrounding environment. In addition, this design also protects the second motor 5, preventing metal debris or dust from entering the motor, affecting the normal operation of the motor or causing safety problems such as short circuits. Not only that, the design of the lock makes the disassembly and assembly of the end cover 601 simple and quick. When it is necessary to clean the inside of the protective cover 602 or replace worn parts, the end cover 601 can be quickly opened for operation, which greatly improves the maintenance efficiency of the equipment. A connecting pipe 1 is installed on the protective cover 602, and a three-way pipe 201 is installed at the end of the connecting pipe 1 facing away from the protective cover 602, and the three-way pipe 201 is located on the dust box 2. The dust generated during grinding is introduced into the dust box 2 through the connecting pipe 1.

[0044] Example 2

[0045] In order to ensure the dust collection box 2 has a dust adsorption effect, for example, Figures 1 to 3As shown, the present invention also includes: the dust collecting box 2 is provided with a top cover 202, the three-way pipe 201 is located on the top cover 202 of the dust collecting box 2, and a fan 203 is installed on the top cover 202 on one side of the three-way pipe 201, the three-way pipe 201 and the fan 203 are symmetrically distributed on the top cover 202, and the partition 205 is located on the center line of the dust collecting box 2, the three-way pipe 201 and the fan 203 are symmetrically distributed on the top cover 202, and this design makes the airflow in the dust collecting box 2 more uniform, reduces the occurrence of airflow turbulence and eddy current phenomenon, and thus improves the dust collection efficiency. The optimized airflow path helps reduce resistance during operation of the fan 203, lowering energy consumption and improving the energy efficiency of the equipment. A first motor 204 is mounted on the fan 203. This first motor 204 drives the fan 203, creating negative pressure within the dust box 2, thereby drawing dust into the dust box 2 through the connecting pipe 1. A partition 205 is provided within the dust box 2, with a notch at its bottom. The notch connects the first and second chambers 207 and 208. When the negative pressure within the second chamber 208 draws the liquid and dust mixture toward the notch, air overflows through the notch into the first chamber 207. This design ensures that dust drawn in with the air is completely absorbed by the liquid within the dust box 2, preventing secondary dust dispersion and contamination. The notch allows the dust and liquid mixture to flow smoothly from the second chamber 208 into the first chamber 207, further improving dust removal efficiency and ensuring a clean working environment. Furthermore, the notch design helps balance the pressure difference between the two chambers, reducing vibration and noise caused by uneven pressure and enhancing the stability of the device. Dust box 2 is filled with liquid, and the liquid level is located five centimeters above the notch. When the negative pressure generated in first chamber 207 draws the liquid level in second chamber 208 to the notch, the air in second chamber 208 overflows through the notch into first chamber 207, ensuring that dust drawn into dust box 2 with the air is completely absorbed by the liquid within. The liquid level is located five centimeters above the notch, forming an effective dust interception zone. When dust particles are drawn into dust box 2 with air, they first come into contact with the liquid and are absorbed, thus preventing them from being dispersed again. This design ensures that dust particles are fully absorbed by the liquid before reaching the notch, significantly improving dust removal efficiency. Furthermore, the presence of the liquid helps reduce dust pollution in the air and improves the working environment. The use of liquid to absorb dust not only reduces the pollution of dust to the environment, but also avoids the secondary pollution that may be caused by traditional dust removal methods.At the same time, this design also helps reduce the energy consumption and operating costs of the equipment. The dust box 2 is separated into a first accommodating chamber 207 and a second accommodating chamber 208 by a partition 205, and the three-way pipe 201 and the fan 203 correspond to the positions of the second accommodating chamber 208 and the first accommodating chamber 207, respectively. A filter 206 is installed in the first accommodating chamber 207, and the filter 206 is located above the liquid level in the dust box 2. The filter 206 ensures the purity of the air entering the fan 203. The filter 206 is located above the liquid level and can further filter out fine dust particles remaining in the air after being adsorbed by the liquid. This design ensures that the air discharged into the atmosphere is cleaner and reduces dust pollution to the environment. The dual effects of initial liquid adsorption and fine filtration by the filter 206 greatly improve the dust removal efficiency. This allows the dust generated during the polishing process to be almost completely collected and processed, maintaining the cleanliness of the working environment. The presence of the filter 206 can prevent dust from directly entering key components such as the fan 203, reducing the risk of dust abrasion and clogging of the fan 203, thereby extending the service life of the fan 203.

[0046] Working principle:

[0047] The second motor 5 is started, and the second motor 5 drives the two symmetrically distributed grinding heads 6 to rotate to grind and polish the surface of the workpiece. The design of the shield 602 and the end cover 601 protects the operator from being hurt by flying debris.

[0048] Start the first motor 204, drive the fan 203 to work, generate negative pressure in the dust box 2, and the dust generated during the grinding process is sucked in through the connecting pipe 1 on the shield 602. The connecting pipe 1 guides the dust to the dust box 2, specifically to the second accommodating chamber 208 of the dust box 2. Under the action of negative pressure, the dust is sucked into the second accommodating chamber 208, and comes into contact with the liquid therein (such as water or a special treatment liquid), and is adsorbed by the liquid. When the liquid level of the second accommodating chamber 208 is drawn to the notch by negative pressure, the air overflows through the notch to the first accommodating chamber 207, ensuring that the dust is fully absorbed. The filtered air enters the first accommodating chamber 207 and is further purified by the filter 206 to remove residual dust particles. The pure air is then discharged by the fan 203, completing the entire dust collection and treatment process.
