Description

Technical Field

[0001] This utility model relates to the field of surface grinding technology, specifically a dust prevention device for surface grinding machines. Background Technology

[0002] Surface grinders primarily use rotating grinding wheels to grind workpieces to achieve the required flatness. Based on the shape of the worktable, they can be divided into rectangular and circular worktables. The main parameters of a rectangular worktable surface grinder are its width and length, while the main parameter of a circular worktable is its diameter. Based on the type of shaft, they can be divided into horizontal and vertical spindle grinders.

[0003] Existing surface grinders are divided into two types: those with an outer protective cover and those without. Surface grinders without an outer protective cover generate a lot of dust during use, which affects the operator's operation. Furthermore, a lot of debris remains on the surface after use, and the debris is difficult to clean due to the large gaps in the operating table.

[0004] Therefore, this utility model provides a dust prevention device for surface grinders to solve the above problems. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below through the accompanying drawings and examples.

[0030] Reference Figures 1 to 5This application provides a dustproof device for a surface grinder, including a base 1, a worktable 4 on the top of the base 1, a main body 5 fixedly mounted on the top of the base 1, a tool holder 6 on the front of the main body 5, a dust removal component 2 on the front of the tool holder 6, and a collection component 3 on the back of the base 1. The dust removal component 2 includes an adjusting block 23, a suction pipe 22 fixedly mounted at the bottom of the adjusting block 23, a dust collection hopper 21 fixedly mounted at the bottom of the suction pipe 22, the dust collection hopper 21 being located above the worktable 4, an extension pipe 24 fixedly mounted at the top of the adjusting block 23, and a through hole connecting the suction pipe 22 and the extension pipe 24 inside the adjusting block 23. The collection component 3 includes a collection box 31 and an air pump 32, a connecting pipe 26 fixedly mounted between the collection box 31 and the extension pipe 24, and a connecting pipe 33 fixedly mounted between the air inlet of the air pump 32 and the collection box 31.

[0031] Two side rods 25 are fixedly mounted on the front of the tool holder 6, and an adjusting block 23 is rotatably connected between the two side rods 25. An electric actuator 27 is hinged between the outer side of the extension tube 24 and the top of the tool holder 6. The extension tube 24 is a rigid metal tube, and the connecting tube 26 is a corrugated tube.

[0032] In this embodiment, air is drawn from the collection box 31 by the air pump 32 and the connecting pipe 33. After the air is drawn out, a negative pressure is formed inside the collection box 31. Once the negative pressure is formed, suction is generated inside the connecting pipe 26, the extension pipe 24, and the suction pipe 22. The suction force is used to draw air from the outside through the dust collection hopper 21. Dust is generated when the equipment is working. At this time, by starting the air pump 32, suction is generated from the dust collection hopper 21 to simultaneously draw air and dust into the collection box 31, thus cleaning the dust and preventing it from being scattered into the air. Furthermore, during the absorption process, the dust can be effectively absorbed. By activating the electric actuator 27, the extension tube 24 can be pulled to swing around the side rod 25, thereby changing the angle of the lower dust collection hopper 21 and thus changing the dust collection angle for better dust removal. After the equipment finishes working, by increasing the suction power of the air pump 32, a greater negative pressure is generated inside the collection box 31, which in turn generates a greater suction power at the dust collection hopper 21. The dust collection hopper 21 can absorb and clean the debris generated after work and the debris inside the equipment table. The swinging dust collection hopper 21 makes the cleaning effect even better.

[0033] Reference Figures 1 to 5 In one aspect of this embodiment, two pairs of magnetic strips 310 are fixedly installed on the left and right inner walls of the collection box 31. A frame 38 is placed on the top of the two magnetic strips 310. A dust filter 39 is fixedly installed inside the frame 38. The connection point between the connecting pipe 26 and the collection box 31 is located above the upper dust filter 39, and the connection point between the connecting pipe 33 and the collection box 31 is located below the lower dust filter 39.

[0034] The frame 38 is made of iron and is attached to the top of the corresponding magnetic strip 310. The front of the collection box 31 is hinged with a door 34, and a handle 35 is fixedly installed on the front of the door 34. An iron plate 36 is fixedly installed on the right side of the front of the door 34, and a magnetic block 37 is fixedly installed on the right side of the collection box 31. The iron plate 36 is attached to the corresponding magnetic block 37, and a sealing rubber gasket is covered on the inside of the door 34.

[0035] In this embodiment, the dust and debris collected by the vacuum cleaner enter the collection box 31 through the connecting pipe 26. The dust and debris are collected by the vacuum filter 39 inside the collection box 31. The holes of the upper vacuum filter 39 are larger than those of the lower vacuum filter 39. The upper vacuum filter 39 is used to adsorb debris, and the lower vacuum filter 39 is used to adsorb dust. The treated air is discharged through the air outlet of the air pump 32. When it is necessary to clean the debris and dust, the box door 34 is opened by the handle 35. When opening, the adsorption between the iron sheet 36 and the magnet block 37 is released by force. After opening, the iron frame 38 is removed from the lower magnet strip 310. After removal, the vacuum filter 39 is cleaned. After cleaning, the vacuum filter 39 is reinstalled. During installation, the frame 38 is adsorbed by the magnet strip 310. After installation, the box door 34 is closed, and the iron sheet 36 is fixed by the magnet block 37. The cleaning of the vacuum filter 39 is completed, thus achieving the effect of convenient cleaning of the vacuum filter 39.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: Air is drawn from the collection box 31 by the air pump 32 and connecting pipe 33. After the air is drawn out, a negative pressure is formed inside the collection box 31. Once the negative pressure is formed, suction is generated inside the connecting pipe 26, extension pipe 24, and suction pipe 22. The suction force draws air from the outside through the dust collection hopper 21. Dust is generated when the equipment is working. At this time, by starting the air pump 32, the suction force generated from the dust collection hopper 21 can simultaneously draw the air and the generated dust into the collection box 31, thus achieving dust removal. To prevent dust from scattering into the air, the electric actuator 27 can be activated during absorption. The extension rod 27's telescopic movement pulls the extension tube 24 to swing around the side rod 25, thus changing the angle of the lower dust collection hopper 21 and achieving a better dust removal effect. After the equipment finishes working, the suction power of the air pump 32 is increased, creating a greater negative pressure inside the collection box 31, resulting in greater suction at the dust collection hopper 21. This allows the dust collection hopper 21 to collect the debris and other contaminants generated during operation. The equipment platform removes debris by suction, and the oscillating dust collection bucket 21 enhances the cleaning effect. The collected dust and debris enter the collection box 31 through the connecting pipe 26, where they are collected by the dust collection filter 39. The upper dust collection filter 39 has larger holes than the lower one; the upper filter 39 is used to collect debris, and the lower filter 39 is used to collect dust. The treated air is discharged through the exhaust port of the air pump 32. When cleaning debris and dust is needed, the box door is opened. 34. Open the door by using handle 35. When opening, forcefully release the attraction between the iron sheet 36 and the magnet 37. After opening, remove the iron frame 38 from the magnet strip 310 below. After removing it, clean the dust filter 39. After cleaning, reinstall the dust filter 39. When reinstalling, simply use the magnet strip 310 to attract the frame 38. After installation, close the door 34 and fix it by using the magnet 37 to attract the iron sheet 36. This completes the cleaning of the dust filter 39, thus achieving the effect of convenient cleaning of the dust filter 39.
