Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a dustproof device for a copper alloy polishing machine. Background Technology

[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Copper alloys need to be polished after production. When the polishing machine is working, it generates a lot of dust due to friction with the grinding parts.

[0003] A search of Chinese patent CN216830386U reveals a dustproof device for a copper polishing machine. The device includes a base, a detachable locking block on one side of the base's bottom, a rotating shaft fixedly sleeved in the middle of the locking block, and a caster wheel movably sleeved on the surface of the rotating shaft. A side mounting block is detachably mounted on one side of the base, a support column is detachably mounted on the top of the side mounting block, a horizontal shaft is fixedly sleeved on one side of the support column, a connecting shaft is detachably mounted on the bottom of the horizontal shaft, and a storage box is detachably mounted on one side of the connecting shaft. A first sliding groove is formed on one side of the top of the base, and a first slider is movably connected inside the first sliding groove. In this design, the dustproof device for the copper polishing machine, through the configuration of a motor and fan, effectively cleans the dust on the copper polishing machine by turning on the motor and driving the fan. This avoids the problem of the device's surface becoming covered in dust over time due to the lack of a dust removal structure, making manual cleaning time-consuming and laborious.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] While the above solutions can remove dust from the polishing machine, the dust will fly everywhere, affecting the safety of the user. The dust can be filtered and collected through the filter, but long-term use will cause the filter to become clogged with dust, affecting its normal use. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a dustproof device for a copper alloy polishing machine, which can automatically clean the filter tube before and after use, thus avoiding the situation where the filter tube is blocked by dust during the polishing process.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a dustproof device for a copper alloy polishing machine, including a processing table, a protective cover, a protective plate, and a movable cover. The protective cover is fixedly installed on the top wall of the processing table, and the protective plate is fixedly installed on the side of the top wall of the processing table away from the protective cover. A dust collection hopper is embedded in the processing table, and a placement platform is provided above the inside of the dust collection hopper. A placement plate is movably installed on the placement platform, and an installation rod fixedly connected to the dust collection hopper is fixedly installed on the placement platform. A filter box is fixedly installed at the bottom of the dust collection hopper, and a collection box is movably installed inside the filter box. A fan is installed on the outer wall of the filter box, and a filter pipe is installed on the input end of the fan. A filtration mechanism is provided inside the dust collection hopper and the filter box.

[0008] In some embodiments, the filtration mechanism includes a drive shaft, a lever, a lever block, a drive sleeve, and a partition. The drive shaft is a cylindrical rod with threads on the upper side wall. The partition is a rectangular plate with a sloping top. The partition is fixedly installed inside the lower part of the dust collection hopper. The drive shaft is rotatably mounted on the partition. The lever is fixedly installed on the bottom wall of the drive shaft. The lever block is fixedly installed vertically upward on the upper side wall of the filter tube. The drive sleeve has a threaded groove inside that matches the drive shaft. The drive sleeve is fixedly installed on the bottom wall of the placement plate and extends downward through the upper and lower walls of the placement platform.

[0009] In some embodiments, both the lever and the lever block are elastic, the transmission sleeve is fitted onto the transmission shaft, and a spring is fitted onto the transmission sleeve, with the spring connected to the placement plate.

[0010] In some embodiments, the filter tube extends through the side wall of the collection box and is located inside the collection box.

[0011] In some embodiments, two movable plates are movably mounted inside the filter box at the position corresponding to the partition via a torsion spring shaft, and the movable plates are restricted by the partition.

[0012] In some embodiments, the placement platform has multiple dust collection ports inside, which are hollow structures that gradually decrease in size from top to bottom, and extend to the bottom wall of the placement platform.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] This invention utilizes a filtration mechanism. Under the influence of gravity, the placement plate moves the transmission sleeve downwards, which then rotates on the transmission shaft. This rotation causes the lever to rotate, which in turn presses against the filter block. Both the lever and the filter block are elastic, causing vibration on the filter tube upon contact. This vibration dislodges dust from the filter tube. Since the transmission sleeve is fitted with a spring, the placement plate returns to its original position after polishing, allowing the transmission sleeve to move and the transmission shaft to rotate again, vibrating the filter tube once more. This achieves automatic cleaning of the filter tube before and after use, preventing dust blockage during polishing. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved dustproof device for a copper alloy polishing machine. The technical solution of this utility model is as follows:

[0025] like Figures 1 to 5 As shown, a dustproof device for a copper alloy polishing machine includes a processing table 1, a protective cover 2, a protective plate 3, and a movable cover 4. The processing table 1 has a rectangular structure, the protective cover 2 has a hollow rectangular structure, and the protective cover 2 is fixedly installed on the top wall of the processing table 1. The protective plate 3 has a rectangular structure and is fixedly installed on the top wall of the processing table 1 away from the protective cover 2. The protective plate 3 has a hollow rectangular structure and is slidably installed inside the protective cover 2. The protective cover 2, the protective plate 3, and the movable cover 4 can seal the top space of the processing table 1, thereby preventing dust from escaping during polishing. A dust collection hopper 5 is embedded in the processing table 1, and the dust collection hopper 5 is arranged from top to bottom... The dust collection hopper 5 has a gradually decreasing hollow truncated pyramid structure. Inside the dust collection hopper 5, there is a placement platform 6. The placement platform 6 is a rectangular plate. A placement plate 7 is movably installed on the placement platform 6. The placement plate 7 is used to place the copper alloy that needs to be polished. A mounting rod 8 is fixedly installed on the placement platform 6 and is fixedly connected to the dust collection hopper 5. The mounting rod 8 is used to install the placement platform 6 and the placement plate 7. A filter box 9 is fixedly installed at the bottom of the dust collection hopper 5. The filter box 9 is a hollow rectangular structure. A collection box 11 is movably installed inside the filter box 9. A fan 10 is installed on the outer wall of the filter box 9. A filter tube 12 is installed on the input end of the fan 10. A filtration mechanism is set inside the dust collection hopper 5 and the filter box 9.

[0026] The filtration mechanism includes a drive shaft 13, a lever 14, a lever block 15, a drive sleeve 16, and a partition plate 17. The drive shaft 13 is a cylindrical rod with threads on the upper side wall. The partition plate 17 is a rectangular plate with a sloping top. The partition plate 17 is fixedly installed inside the lower part of the dust collection hopper 5, and the drive shaft 13 is rotatably mounted on the partition plate 17. The lever 14 is a long rectangular strip and is fixedly installed on the bottom wall of the drive shaft 13. The lever block 15 is a rectangular block. Both the lever 14 and the lever block 15 are elastic, and the lever block 15 is vertically oriented. The transmission sleeve 16 is a hollow cylindrical structure, fixedly installed on the upper side wall of the filter tube 12. The transmission sleeve 16 has a threaded groove inside that matches the transmission shaft 13. The transmission sleeve 16 is fixedly installed on the bottom wall of the placement plate 7, extending downwards through the upper and lower walls of the placement platform 6, and is sleeved on the transmission shaft 13. A spring is fitted onto the transmission sleeve 16 and connected to the placement plate 7. When polishing the copper alloy, the copper alloy is first placed on the placement plate 7, and then polishing can be performed on the placement plate 7. Polishing is performed while the blower 10 is activated. The blower 10 generates suction inside the dust collection hopper 5 through the filter pipe 12, drawing the polishing dust into the filter box 9 and filtering it through the filter pipe 12. Due to the filtration mechanism, under gravity, the placement plate 7 moves the transmission sleeve 16 downwards. The transmission sleeve 16 is fitted onto the transmission shaft 13, causing the transmission shaft 13 to rotate. The rotation of the transmission shaft 13 drives the lever 14 to rotate, which in turn presses the lever 14 against the lever 15. All rods 14 are elastic, so that when the lever 14 contacts the lever block 15, it can vibrate on the filter tube 12. The vibration can shake off the dust on the filter tube 12. Since the transmission sleeve 16 is fitted with a spring, after polishing is completed, the placement plate 7 will be reset under the action of the spring, which can then drive the transmission sleeve 16 to move and the transmission shaft 13 to rotate again, and then vibrate the filter tube 12 again. This achieves the effect of automatically cleaning the filter tube 12 before and after use, avoiding the situation where the filter tube 12 is blocked by dust during the polishing process.

[0027] The filter tube 12 runs through the side wall of the collection box 11 and is located inside the collection box 11. When the filter tube 12 vibrates, the falling dust will be collected inside the collection box 11. Then the collection box 11 can be pulled out from inside the filter box 9 for easy dust treatment.

[0028] Inside the filter box 9, corresponding to the position of the partition 17, there are two movable plates 18 that are movably installed via a torsion spring shaft. The movable plates 18 are rectangular plates. The movable plates 18 are restricted by the partition 17, so that the movable plates 18 can only be flipped downwards. When collecting dust, the movable plates 18 flip downwards to facilitate the passage of dust. After the dust collection is completed, the movable plates 18 will return to their original position and then seal the filter box 9 to prevent dust from escaping.

[0029] The placement platform 6 has multiple dust collection ports 19 inside. The dust collection ports 19 are hollow structures that gradually decrease in size from top to bottom. The dust collection ports 19 extend to the bottom wall of the placement platform 6. The dust collection ports 19 can discharge the dust that falls into the placement platform 6 and avoid affecting the normal movement of the placement plate 7.

[0030] The specific working method is as follows:

[0031] When polishing copper alloy is required, the copper alloy is first placed on the placement plate 7. Polishing can then be performed on the placement plate 7. Simultaneously, the fan 10 is activated. The fan 10 generates suction inside the dust collection hopper 5 through the filter pipe 12, drawing the polishing dust into the filter box 9, where it is filtered by the filter pipe 12. Due to the filtration mechanism, under the influence of gravity, the placement plate 7 moves the transmission sleeve 16 downwards. The transmission sleeve 16 is fitted onto the transmission shaft 13, causing the transmission shaft 13 to rotate. The rotation of the transmission shaft 13 drives the lever 14 to rotate. The rotation of 4 can squeeze the paddle 15. Both the paddle 15 and the lever 14 are elastic, so that the lever 14 can vibrate on the filter tube 12 after contacting the paddle 15. The vibration can shake off the dust on the filter tube 12. Since the transmission sleeve 16 is fitted with a spring, after polishing is completed, the placement plate 7 will be reset under the action of the spring, which can then drive the transmission sleeve 16 to move and the transmission shaft 13 to rotate again, and then vibrate the filter tube 12 again. This achieves the effect of automatically cleaning the filter tube 12 before and after use, avoiding the situation where the filter tube 12 is blocked by dust during the polishing process.

Matters not covered in this utility model are common knowledge to those skilled in the art.
