Description
A dust removal device for a polishing machine Technical Field
[0001] This utility model relates to the field of polishing machine technology, specifically to a dust removal device for polishing machines. Background Technology
[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, friction is applied to the surface to be polished, thereby removing paint contamination, oxide layers, and shallow scratches. The polishing disc's rotation speed is generally between 1500-3000 rpm, mostly with stepless speed regulation, which can be adjusted as needed during operation. Polishing machines generate a lot of dust during use. If this dust is not removed promptly, it may affect the quality of the workpiece. Therefore, a dust removal device for polishing machines is proposed to solve the aforementioned problem. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a dust removal device for a polishing machine, which addresses the shortcomings of the prior art.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dust removal device for a polishing machine, including a slide, on which a dust removal mechanism and a shaking mechanism are respectively arranged;
[0005] The dust removal mechanism includes: a dust collection box slidably connected to a carriage; an installation frame connected to the inner wall of the dust collection box; several dust filter bags connected to the installation frame; an exhaust fan connected to the top of the dust collection box; the input end of the exhaust fan being connected to the dust collection box via a pipe; a suction pipe connected to the right side of the dust collection box; and a suction hood connected to the right end of the suction pipe. When the exhaust fan is activated, a negative pressure is generated inside the dust collection box, and the dust generated during polishing is sucked into the dust collection box through the suction hood and suction pipe. The dust filter bags filter the dust, and the purified air is discharged.
[0006] The shaking mechanism includes a fixed plate, a support plate, and a connecting plate. The fixed plate is connected to the top of the slide, and a spring connects the fixed plate to the dust collector. The support plate is connected to the front of the slide, and a motor is connected to the top of the support plate. A rotating shaft is connected to the output end of the motor, and a turntable is connected to the top of the rotating shaft. A push rod is connected to the top of the turntable. The connecting plate is connected to the front of the dust collector, and a sliding plate is connected to the front of the connecting plate. By starting the motor, the turntable and the eccentric push rod are driven to rotate. The push rod presses the arc-shaped sliding plate, causing the sliding plate to drive the connecting plate and the dust collector to slide along the slide groove of the slide. The movement of the dust collector compresses the spring, and under the elastic action of the spring, the dust collector shakes back and forth, thereby causing the dust adhering to the surface of the filter bag inside the dust collector to fall off, preventing the filter pores from clogging and maintaining continuous and efficient dust removal.
[0007] Preferably, the front of the slide plate is arc-shaped, the push rod is eccentrically positioned, and its outer wall is in contact with the slide plate, ensuring that the push rod can contact the slide plate when the turntable rotates, thereby converting the circular motion of the turntable into the linear reciprocating motion of the dust collection box.
[0008] Preferably, there are two springs, which are arranged opposite each other on the fixed plate to provide balanced elastic support and reduce lateral displacement when the dust collection box shakes. The suction pipe is a retractable hose to avoid pipe stretching and damage, and to ensure that the suction path is always unobstructed.
[0009] Preferably, the slide is provided with a sliding groove, and the bottom of the dust collection box is slidably connected in the sliding groove. The sliding groove provides precise guidance for the dust collection box, ensuring that it moves in a straight line during the shaking process.
[0010] Preferably, the bottom of the dust collector is connected to a dust discharge channel, which collects the dust shaken off the filter bags, facilitating the centralized discharge of dust. The dust collector is also equipped with a sealing mechanism.
[0011] Preferably, the sealing mechanism includes: an electric hydraulic cylinder, which is connected to the bottom of the dust collection box via a bracket. The electric hydraulic cylinder is self-locking, and a sealing plate is connected to the piston end of the electric hydraulic cylinder. A sealing gasket is connected to the top of the sealing plate and fits against the bottom of the ash discharge channel. By activating the electric hydraulic cylinder, the sealing plate is moved to open the bottom of the ash discharge channel, facilitating the unified discharge of dust collected in the ash discharge channel.
[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0013] 1. This dust removal device for a polishing machine generates negative pressure in the dust collection box by starting the exhaust fan. The dust generated during polishing is drawn into the dust collection box through the dust hood and suction pipe. The dust is filtered by the dust bag, and the purified air is discharged. The motor drives the turntable and eccentric push rod to rotate. The push rod presses the arc-shaped sliding plate, causing the sliding plate to move the connecting plate and the dust collection box along the slide rail. The movement of the dust collection box compresses the spring. Under the elastic action of the spring, the dust collection box vibrates back and forth, thereby causing the dust adhering to the surface of the dust bag in the dust collection box to fall off, avoiding filter pore blockage and maintaining continuous and efficient dust removal.
[0014] 2. This dust removal device for a polishing machine collects dust shaken off from the filter bag through a set dust discharge channel. By starting an electric hydraulic cylinder, the sealing plate is moved to open the bottom of the dust discharge channel, which facilitates the unified discharge of dust collected in the dust discharge channel.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.
[0024] Please refer to Figures 1-4. One embodiment of this utility model is: a dust removal device for a polishing machine, including a slide 1, on which a dust removal mechanism 2 and a shaking mechanism 3 are respectively arranged; the dust removal mechanism 2 includes: a dust removal box 21, which is slidably connected to the slide 1. The slide 1 has a sliding groove, and the bottom of the dust removal box 21 is slidably connected to the sliding groove. The sliding groove provides precise guidance for the dust removal box 21, ensuring that it moves in a straight line during shaking. Support legs are connected to the four corners of the bottom of the slide 1. A mounting frame 22 is connected to the inner wall of the dust removal box 21, and several dust filter bags 23 are connected to the mounting frame 22. A top-mounted exhaust fan 24 is connected to the dust collection box 21 via a pipe. A suction pipe 25 is connected to the right side of the dust collection box 21, and a suction hood 26 is connected to the right end of the suction pipe 25. The suction pipe 25 is a flexible hose to prevent damage from stretching and to ensure unobstructed suction. When the exhaust fan 24 is activated, a negative pressure is created inside the dust collection box 21, drawing polishing dust into the dust collection box 21 through the suction hood 26 and suction pipe 25. The dust is filtered by the dust bag 23, and the purified air is discharged. The shaking mechanism 3 includes a fixed plate 31, a support plate 33, and a connecting plate 38. The fixed plate 31 is connected to the slide. At the top of the carriage 1, a spring 32 connects the fixed plate 31 to the dust collection box 21. There are two springs 32, which are arranged opposite each other on the fixed plate 31 to provide balanced elastic support and reduce lateral displacement when the dust collection box 21 shakes. A support plate 33 is connected to the front of the carriage 1. A motor 34 is connected to the top of the support plate 33. A rotating shaft 35 is connected to the output end of the motor 34. A turntable 36 is connected to the top of the rotating shaft 35. A push rod 37 is connected to the top of the turntable 36. A connecting plate 38 is connected to the front of the dust collection box 21. A sliding plate 39 is connected to the front of the connecting plate 38. The front of the sliding plate 39 is arc-shaped. The push rod 37 is eccentrically positioned. Furthermore, the outer wall fits snugly against the slide plate 39, ensuring that the push rod 37 can contact the slide plate 39 when the turntable 36 rotates. This converts the circular motion of the turntable 36 into the linear reciprocating motion of the dust collector 21. The starter motor 34 drives the turntable 36 and the eccentric push rod 37 to rotate. The push rod 37 presses against the arc-shaped slide plate 39, causing the slide plate 39 to drive the connecting plate 38 and the dust collector 21 to slide along the slide groove of the slide frame 1. The dust collector 21 moves to compress the spring 32. Under the elastic action of the spring 32, the dust collector 21 vibrates back and forth, thereby causing the dust adhering to the surface of the filter bag 23 inside the dust collector 21 to fall off, preventing the filter holes from clogging and maintaining continuous and efficient dust removal.
[0025] Working principle: The dust collection hood 26 is fixed to the polishing machine with bolts. During the polishing process, the exhaust fan 24 is started, and negative pressure is generated in the dust collection box 21. The dust generated during polishing is sucked into the dust collection box 21 through the dust collection hood 26 and the dust collection pipe 25. The dust filter bag 23 filters the dust, and the purified air is discharged. The start motor 34 drives the turntable 36 and the eccentric push rod 37 to rotate. The push rod 37 squeezes the arc-shaped slide plate 39, which causes the slide plate 39 to drive the connecting plate 38 and the dust collection box 21 to slide along the slide groove of the slide frame 1. The movement of the dust collection box 21 compresses the spring 32. Under the elastic action of the spring 32, the dust collection box 21 vibrates back and forth from side to side, thereby causing the dust adhering to the surface of the dust filter bag 23 in the dust collection box 21 to fall off, avoiding filter pore blockage and maintaining continuous and efficient dust removal.
[0026] Please refer to Figures 1-4. In another embodiment of this utility model, based on the above embodiments, the bottom of the dust collector 21 is connected to a dust discharge channel 27. The dust shaken off by the dust filter bag 23 is collected through the dust discharge channel 27, which facilitates the centralized discharge of dust. The dust collector 21 is provided with a sealing mechanism 4, which includes an electric hydraulic cylinder 41. The electric hydraulic cylinder 41 is connected to the bottom of the dust collector 21 through a bracket. The electric hydraulic cylinder 41 is self-locking. The piston end of the electric hydraulic cylinder 41 is connected to a sealing plate 42. The top of the sealing plate 42 is connected to a sealing gasket and fits against the bottom of the dust discharge channel 27. By starting the electric hydraulic cylinder 41, the sealing plate 42 is driven to move and open the bottom of the dust discharge channel 27, which facilitates the unified discharge of dust collected by the dust discharge channel 27.
[0027] Working principle: The dust shaken off by the filter bag 23 is collected through the dust discharge channel 27. The sealing plate 42 is moved and opened by the start of the electric hydraulic cylinder 41, so that the dust collected by the dust discharge channel 27 can be discharged uniformly.
[0028] It is worth noting that the exhaust fan 24, motor 34, and electric hydraulic cylinder 41 in the above embodiments are all commonly used devices in the prior art. The models used can be customized according to actual usage requirements. Furthermore, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to achieve control. The circuit control, specific composition, and principle involved are all prior art and are well known in the current field. They are clear to those skilled in the art, so they will not be described in detail here.
[0029] This utility model provides a dust removal device for a polishing machine. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
