Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a dust collection device for glass polishing. Background Technology

[0002] Glass is an amorphous solid, mainly composed of silicon dioxide. Polishing is crucial in glass processing. It can eliminate surface imperfections, improve flatness, optimize glass edges, enhance aesthetics and safety, and allow glass to better meet various needs.

[0003] During the glass polishing process, a large amount of dust is generated. To reduce the inhalation of dust by workers and protect their health, vacuuming equipment is usually used. Current vacuuming equipment mainly consists of a frame, a suction structure, and a filter. Its working principle is that the suction structure is responsible for sucking up the dust generated during glass polishing, and then the filter screen filters out the dust.

[0004] However, after prolonged use, dust accumulates on the filter screen and clogs the filter holes. This requires a long downtime for the machine to be manually removed for cleaning or replacement. This process is not only cumbersome but also seriously affects production efficiency. Furthermore, the degree of automation is low, which cannot meet the needs of high-efficiency production.

[0005] Therefore, a dust collection device for glass polishing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a dust collection device for glass polishing to solve the above-mentioned problems.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A dust collection device for glass polishing includes a cabinet. The top of the cabinet has a dust collection mechanism extending into its interior. The exhaust end of the dust collection mechanism has a corrugated pipe, and the lower end of the corrugated pipe has an annular disc. A height adjustment mechanism is provided between the annular disc and the cabinet for adjusting the height of the annular disc. The inner side wall of the cabinet has a rotating mechanism with multiple filter cartridges arranged in a ring on the rotating mechanism. The end of each filter cartridge away from the rotating mechanism is open, and the open end of one of the filter cartridges abuts against the bottom of the annular disc. The inner side wall of the cabinet has a cleaning mechanism for cleaning impurities from the surface of the filter cartridges.

[0009] Preferably, the dust collection mechanism includes a centrifugal fan, a first connecting pipe, a fixing frame, a hollow strip, dust collection holes, and a second connecting pipe. The top of the cabinet is equipped with a centrifugal fan, and the air inlet of the centrifugal fan is equipped with the first connecting pipe. The first connecting pipe is fixedly fitted with a fixing frame whose lower end is connected to the top of the cabinet. The other end of the first connecting pipe is equipped with a hollow strip, and multiple dust collection holes are evenly opened on the hollow strip. The air outlet of the centrifugal fan is equipped with the second connecting pipe that penetrates into the interior of the cabinet. The lower end of the second connecting pipe is connected to the upper end of the corrugated pipe.

[0010] Preferably, the height adjustment mechanism includes a connecting plate and an electric push rod. The outer curved surface of the annular disc is provided with the connecting plate, and the inner top wall of the cabinet is provided with an electric push rod connected to the outer side of the connecting plate via a telescopic shaft.

[0011] Preferably, the rotary transposition mechanism includes a drive shaft, a connecting rod, and a motor. The inner side wall of the cabinet is provided with a drive shaft, and the outer side of the cabinet is provided with a motor whose output shaft passes through the interior. The output shaft of the motor is coaxially connected to the other end of the drive shaft. The filter cylinder is provided with a connecting rod at one end near the drive shaft, the other end of which is connected to the outer curved surface of the drive shaft.

[0012] Preferably, the cleaning mechanism includes an electric push rod II, a cylinder, a cylindrical brush, and brush bristles. The inner side wall of the cabinet is provided with an electric push rod II. The telescopic shaft of the electric push rod II is provided with a cylinder. The cylinder corresponds to one of the filter cylinders. The inner side wall of the cylinder is provided with a cylindrical brush extending along the length direction. The inner curved surface of the cylinder is uniformly provided with brush bristles.

[0013] Preferably, the bottom of the annular disc is provided with a sealing ring, and the open end of the filter cylinder is provided with a sealing groove that matches the sealing ring.

[0014] Preferably, the cabinet has a frame on its outer side, a filter screen on the inner side wall of the frame, and a cabinet door on its body.

[0015] Preferably, the cabinet is equipped with a controller on the outside, casters at the four corners of the bottom of the cabinet, and handles on the outside of the cabinet.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Traditional vacuum cleaners require long downtime for cleaning or replacement due to filter blockage. However, this equipment, when the filter cartridge holes are blocked, uses a height adjustment mechanism to move the annular disc upward to dislodge the blocked filter cartridge. At the same time, a rotation and repositioning mechanism quickly adjusts the position of multiple filter cartridges, rotating a new filter cartridge to the appropriate position. Then, the height adjustment mechanism moves the annular disc downward to hold the new filter cartridge and continue filtering. The entire process does not require long downtime for cleaning or replacement, ensuring the continuous operation of glass polishing and thus significantly improving production efficiency.

[0018] 2. In the past, manual cleaning of filter components required a series of complicated steps such as disassembly, cleaning, and installation. This equipment is equipped with a cleaning mechanism that automatically cleans the clogged filter cartridge after it is replaced. The electric push rod drives the cylinder to move back and forth continuously, using cylindrical brushes and bristles to brush the inner and outer walls of the filter cartridge simultaneously, automatically completing the dust removal. This greatly reduces the manual operation steps and the complexity of operation.

[0019] 3. The system automatically switches from automatic switching when the filter cartridge is clogged to automatic cleaning of the clogged filter cartridge. The entire process requires minimal manual intervention. The height adjustment mechanism, rotation and repositioning mechanism, and cleaning mechanism work together to automatically perform corresponding actions based on the clogging status of the filter cartridge. This achieves automated operation during equipment operation, improves the automation level of the equipment, and meets the requirements of modern high-efficiency production for the degree of equipment automation.

[0030] In this embodiment, by Figure 1-4 Provided is a dust collection device for glass polishing. The present invention includes a cabinet 1, a dust collection mechanism 2 extending through the top of the cabinet 1, a corrugated pipe 31 at the air outlet of the dust collection mechanism 2, an annular disc 32 at the lower end of the corrugated pipe 31, a height adjustment mechanism 4 between the annular disc 32 and the cabinet 1 for adjusting the height position of the annular disc 32, a rotation and repositioning mechanism 5 on the inner side wall of the cabinet 1, a plurality of filter cylinders 6 arranged in a ring on the rotation and repositioning mechanism 5, the end of the filter cylinder 6 away from the rotation and repositioning mechanism 5 being open, and the open end of one of the filter cylinders 6 abutting against the bottom of the annular disc 32, and a cleaning mechanism 7 on the inner side wall of the cabinet 1 for cleaning impurities on the surface of the filter cylinders 6.

[0031] In this embodiment, the dust generated during glass grinding is sucked away by the dust suction mechanism 2 and transported to the corrugated pipe 31 and the annular disk 32. Then, it is transported to the filter cylinder 6 that abuts against the annular disk 32, so that the dust can be filtered by the filter holes on the filter cylinder 6. After a long period of filtration, the dust will clog the filter holes on the filter cylinder 6. At this time, the height adjustment mechanism 4 drives the annular disk 32 to move upward, so that it moves away from the filter cylinder 6. At the same time, the rotation and repositioning mechanism 5 adjusts the position of multiple filter cylinders 6. Meanwhile, the height adjustment mechanism 4 drives the annular disk 32 to move downward, so that the annular disk 32 abuts against the new filter cylinder 6, so that the new filter cylinder 6 can filter the dust. This avoids long downtime and improves production efficiency. At the same time, the cleaning mechanism 7 cleans the clogged filter cylinder 6 to replace manual cleaning, reduce the cumbersomeness of operation, improve the automation level of the equipment, and meet the needs of high-efficiency production.

[0032] Preferably, as another embodiment of the present invention, the dust collection mechanism 2 includes a centrifugal fan 21, a first connecting pipe 22, a fixing frame 23, a hollow strip 24, a dust collection hole 25, and a second connecting pipe 26. The top of the cabinet 1 is provided with a centrifugal fan 21, and the air inlet of the centrifugal fan 21 is provided with a first connecting pipe 22. The first connecting pipe 22 is fixedly fitted with a fixing frame 23 whose lower end is connected to the top of the cabinet 1. The other end of the first connecting pipe 22 is provided with a hollow strip 24. Multiple dust collection holes 25 are evenly opened on the hollow strip 24. The air outlet of the centrifugal fan 21 is provided with a second connecting pipe 26 that penetrates into the interior of the cabinet 1. The lower end of the second connecting pipe 26 is connected to the upper end of the corrugated pipe 31.

[0033] In this embodiment, the centrifugal fan 21 serves as a power source and generates negative pressure at its air intake during operation. This negative pressure is transmitted through the first connecting pipe 22, which is equipped with a fixing bracket 23 for stable fixation to the top of the cabinet 1. Multiple dust suction holes 25 are evenly distributed on the hollow strip plate 24 at the other end of the first connecting pipe 22. Under the action of negative pressure, the dust generated by glass grinding is sucked into the hollow strip plate 24 through these dust suction holes 25 and then enters the first connecting pipe 22. Afterward, the dust-laden air enters through the air intake of the centrifugal fan 21. Under the action of the centrifugal fan 21, the airflow is guided to the air outlet and passes through the second connecting pipe 26. Since the lower end of the second connecting pipe 26 is connected to the upper end of the corrugated pipe 31, the dust-laden air is finally transported to the corrugated pipe 31, thereby completing the dust suction and transportation process of the dust suction mechanism 2.

[0034] Preferably, as another embodiment of the present invention, the height adjustment mechanism 4 includes a connecting plate 41 and an electric push rod 42. The outer curved surface of the annular disk 32 is provided with the connecting plate 41, and the inner top wall of the cabinet 1 is provided with an electric push rod 42 that is connected to the outer side of the connecting plate 41 by a telescopic shaft.

[0035] In this embodiment, the height position of the annular disk 32 is adjusted by extending and retracting the electric push rod 42, so as to realize the subsequent operation of switching the dust filter between different filter cartridges 6.

[0036] When a filter cartridge 6 becomes clogged due to prolonged filtration, the electric push rod 42 can move the connecting plate 41 and the annular disk 32 upwards, away from the filter cartridge 6, so that the filter cartridge 6 can be rotated and repositioned. This also facilitates the cleaning mechanism 7 to clean the clogged filter cartridge 6. At the same time, the electric push rod 42 can move the connecting plate 41 and the annular disk 32 downwards, so that they can press against the new filter cartridge 6, so that the new filter cartridge 6 can be used to filter dust, thereby improving the filtration efficiency and automation of the equipment, avoiding long-term downtime, and ensuring the continuity of production.

[0037] Preferably, as another embodiment of the present invention, the rotary displacement mechanism 5 includes a drive shaft 51, a connecting rod 52 and a motor 53. The inner side wall of the cabinet 1 is provided with the drive shaft 51, and the outer side of the cabinet 1 is provided with a motor 53 whose output shaft passes through the inside. The output shaft of the motor 53 is coaxially connected to the other end of the drive shaft 51. The filter cylinder 6 is provided with a connecting rod 52 whose other end is connected to the outer curved surface of the drive shaft 51 at one end near the drive shaft 51.

[0038] In this embodiment, when the filter cartridge 6 needs to be rotated and repositioned, the motor 53 starts working, and the output shaft of the motor 53 rotates. Since it is coaxially connected to the transmission shaft 51, it will drive the transmission shaft 51 to rotate together. The filter cartridge 6, which is connected to the outer curved surface of the transmission shaft 51 through the connecting rod 52, will rotate around the axis of the transmission shaft 51 under the drive of the transmission shaft 51. In this way, the used filter cartridge 6, which may be blocked by dust, can be rotated aside, and the unused filter cartridge 6 can be rotated to the working position. The height adjustment mechanism 4 drives the annular disk 32 to move down, so that the annular disk 32 abuts against the new filter cartridge 6, so that the new filter cartridge 6 can be used to filter the dust. This ensures that the equipment can continue to filter during the filtration process, avoids downtime for cleaning or replacement due to the blockage of the filter cartridge 6, improves the working efficiency and automation of the equipment, and meets the needs of high-efficiency production. At the same time, through the operation of the rotation and repositioning mechanism 5, different filter cartridges 6 can be easily recycled and maintained, ensuring the continuous and stable operation of the equipment.

[0039] Preferably, as another embodiment of the present invention, the cleaning mechanism 7 includes an electric push rod 71, a cylinder 72, a cylindrical brush 73, and brush bristles 74. The inner side wall of the cabinet 1 is provided with the electric push rod 71, and the telescopic shaft of the electric push rod 71 is provided with a cylinder 72. The cylinder 72 corresponds to one of the filter cylinders 6. The inner side wall of the cylinder 72 is provided with a cylindrical brush 73 extending along the length direction, and the inner curved surface of the cylinder 72 is uniformly provided with brush bristles 74.

[0040] In this embodiment, when the filter cartridge 6 needs to be cleaned, the electric push rod 71 is activated, and the telescopic shaft of the electric push rod 71 begins to extend and retract, thereby driving the cylinder 72 and its cylindrical brush 73 and bristles 74 to extend and retract. During the extension and retraction process, the cylindrical brush 73 brushes the inner wall of the filter cartridge 6, while the bristles 74 brushes the outer wall of the filter cartridge 6. Through this brushing method, dust and impurities attached to the inner and outer walls of the filter cartridge 6 can be brushed off, completing the cleaning operation of the filter cartridge 6.

[0041] Preferably, in another embodiment of the present invention, the bottom of the annular disk 32 is provided with a sealing ring 81, and the open end of the filter cylinder 6 is provided with a sealing groove 82 that matches the sealing ring 81.

[0042] In this embodiment, when the sealing ring 81 at the bottom of the annular disk 32 and the sealing groove 82 at the opening end of the filter cylinder 6 cooperate with each other, the sealing ring 81 will be squeezed into the sealing groove 82, filling any gaps that may exist between the annular disk 32 and the filter cylinder 6. In this way, during the operation of the equipment, the dust suction airflow can be prevented from leaking from the connection between the annular disk 32 and the filter cylinder 6, ensuring that the airflow passes through the filter cylinder 6 along a predetermined path for filtration, thereby ensuring the dust suction and filtration effect.

[0043] Preferably, as another embodiment of the present invention, the cabinet body 1 is provided with a frame 91 on the outside, a filter screen 92 is provided on the inner side wall of the frame 91, and a cabinet door 10 is provided on the cabinet body 1.

[0044] In this embodiment, the filter screen 92 on the outer frame 91 of the cabinet 1 can perform secondary filtration on the exhaust air, intercept residual dust to purify the air and reduce pollution; the cabinet door 10 on the cabinet 1 can be opened to remove the dust accumulated inside the cabinet 1, which facilitates equipment maintenance, ensures its normal operation and centralized dust disposal.

[0045] Preferably, as another embodiment of the present invention, a controller is provided on the outside of the cabinet 1, casters 11 are provided at the four corners of the bottom of the cabinet 1, and handles 12 are provided on the outside of the cabinet 1.

[0046] In this embodiment, the controller on the outside of the cabinet 1 is used to regulate the electrical operation of the equipment, thereby controlling the operation of the vacuuming mechanism 2, the height adjustment mechanism 4, the rotation and repositioning mechanism 5, and the cleaning mechanism 7; the casters 11 at the four corners of the bottom of the cabinet 1 facilitate the movement of the equipment and can flexibly adjust the position of the equipment to meet the needs of different work scenarios; the handles 12 on the outside of the cabinet 1 make it convenient for staff to push or pull the equipment, and in conjunction with the casters, make the movement of the equipment more convenient and effortless.

[0047] Working principle: In the glass polishing operation, the dust collection mechanism 2 plays its role first. The centrifugal fan 21 at the top of the cabinet 1 starts and creates negative pressure at the air intake, so that the dust generated by polishing is sucked in by the dust collection hole 25 on the hollow strip plate 24 at the other end of the connecting pipe 1 22. The dust is sent to the centrifugal fan 21 through the connecting pipe 1 22, and then sent to the corrugated pipe 31 and the annular disc 32 through the connecting pipe 2 26.

[0048] As time goes by, the filter holes of the filter cartridge 6 will be clogged by dust due to continuous filtration. At this time, the height adjustment mechanism 4 will intervene, the electric push rod 42 on the top wall of the cabinet 1 will retract, and the outer curved connecting plate 41 of the annular disk 32 will be pulled, so that the annular disk 32 will move upward and get away from the clogged filter cartridge 6.

[0049] Immediately afterwards, the rotary switching mechanism 5 operates. The motor 53 on the outside of the cabinet 1 drives the transmission shaft 51, and through the connecting rod 52, multiple filter cartridges 6 rotate around the transmission shaft 51. The unclogged filter cartridges 6 are rotated to the docking position. Then, the electric push rod 42 extends, causing the annular disk 32 to move down and block the new filter cartridge 6, continuing the filtration work. The whole process does not require long-term machine downtime, ensuring production efficiency.

[0050] After the filter cartridge 6 is switched, the cleaning mechanism 7 starts to work. The electric push rod 71 on the inner side wall of the cabinet 1 drives the connected cylinder 72 to approach the replaced clogged filter cartridge 6. The cylindrical brush 73 and the inner curved brush 74 on the inner side wall of the cylinder 72 brush the inner and outer walls of the filter cartridge 6 respectively to remove dust. The whole process is automated, reducing the tediousness of manual operation and meeting the needs of high-efficiency production.
