Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices, and in particular relates to a continuous grinding device with a collecting function. Background Art

[0002] Graphite and other objects will produce a large amount of powder and dust during the grinding process, which poses varying degrees of threat to the air environment, as well as human respiratory tract, skin, and eye health; wearing a mask cannot fundamentally solve the problem.

[0003] In order to reduce this pollution, the best solution is to collect the powder generated at the source of grinding. The most common way to collect powder is negative pressure collection. However, practical experience shows that due to the existence of static electricity and other reasons, negative pressure cannot extract all the powder. There will always be some powder still attached to the object, which will diffuse into the air after a period of time.

[0004] Therefore, the present invention proposes a grinding device which can significantly improve the powder collection rate. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a continuous grinding device with a collection function. Since negative pressure cannot collect all the powder, the present invention takes a different approach and uses negative pressure collection as the basis. By applying a small amount of water around the grinding area, the powder is prevented from diffusing into the air. As long as the powder does not diffuse into the air, subsequent cleaning by other means will be much simpler. Based on this, the present invention creatively proposes an automatic constant-pressure water supply mechanism, which can manually and freely control the water supply by pressing, and form a positive pressure chamber with constant pressure in the water tank by extracting the negative pressure of the powder. The liquid is supplied by this positive pressure. The whole process has a clever structure, simple operation, and outstanding effect, and it has excellently solved the problem of excessive powder dust and difficulty in collection during the grinding process.

[0046] The press-type pre-tightening grinding mechanism 1 allows a small relative sliding between the grinding assembly 6 and the handheld driving assembly 4, so that the operator can press by hand movements to control the amount of liquid used to clean dust.

[0048] The elastic preload assembly 5 includes a preload sleeve 11 and a preload spring 12 . The preload sleeve 11 is provided with a square groove 18 . The preload sleeve 11 is slidably engaged with the square groove 18 and is arranged on the square shaft 17 . The preload spring 12 is arranged between the bottom of the square groove 18 and the square shaft 17 .

[0049] Through the cooperation between the square groove 18 and the square shaft 17, the preload sleeve 11 can also cause the grinding assembly 6 to move axially relative to the motor mounting plate 7 while following the rotation of the output shaft 16, thereby driving and controlling the operation of the automatic constant pressure water supply mechanism 3.

[0050] The grinding assembly 6 includes a grinding disc 13 and a detachable grinding wheel disc 14 . The grinding disc 13 is provided with a second center hole 19 . The grinding disc 13 is fixedly connected to the preload sleeve 11 through the second center hole 19 . The detachable grinding wheel disc 14 is detachably provided on the grinding disc 13 .

[0051] The automatic constant pressure water supply mechanism 3 includes a push-type water control component 27, a sedimentation dust collection component 28, a pressure control component 29 and an exhaust component 30. The push-type water control component 27 is arranged on the outside of the air collection hood 21, the sedimentation dust collection component 28 is placed on an open ground, the pressure control component 29 is located at the top of the sedimentation dust collection component 28, and the exhaust component 30 is arranged in the pressure control component 29.

[0052] The push-type water control component 27 includes a water diversion baffle 31 and a sponge ring 32. The water diversion baffle 31 is fixedly connected to the outside of the air collecting hood 21. A water diversion pipe 43 is provided on the top of the water diversion baffle 31. A water diversion joint 44 is provided on the water diversion pipe 43. An annular holder 46 is provided at the bottom of the water diversion baffle 31. The sponge ring 32 is engaged in the annular holder 46. The water diversion pipe 43 and the annular holder 46 are connected through a downpipe 45 evenly distributed in an annular shape.

[0053] The sponge ring 32 has automatic rebound characteristics and capillary phenomena. Through repeated squeezing and rebounding, the liquid in the water distribution pipe 43 can be drawn out through the sponge ring 32, and the liquid is applied around the grinding area through the sponge ring 32, which can wet the powder that is difficult to extract through the air. It can be cleaned up later by other means to ensure that the part of the powder that cannot be extracted will not diffuse freely into the air.

[0054] The sedimentation dust collecting assembly 28 includes a water tank 33, a partition plate 34, a mesh plate 35, a constant pressure water supply pipe 36 and a top cover plate 51. The water tank 33 is placed on an open ground. The partition plate 34 is arranged in the water tank 33. The partition plate 34 is composed of a longitudinal plate portion 47 and a transverse plate portion 48. The mesh plate 35 is arranged on the side of the transverse plate portion 48. The top cover plate 51 is arranged on the top of the water tank 33. The constant pressure water supply pipe 36 passes through the top cover plate 51 and is connected to the water diversion joint 44. An elbow portion 26 is provided at the end of the air collecting pipe 22. The elbow portion 26 is located in the water tank 33. The air collecting pipe 22 passes through the top cover plate 51.

[0055] For graphite powder and other water-insoluble substances, after being clarified by the water storage tank 33, the upper layer of water near the constant pressure water supply pipe 36 is relatively clean and can be used to wet the surroundings of the grinding area to avoid dust. The partition plate 34 can also block the high-pressure airflow ejected from the elbow 26 from stirring the water below and affecting clarification.

[0056] The pressure control assembly 29 includes a top bracket 37, an adjusting screw 38 and a pressure control spring 39. The top bracket 37 is arranged on the exhaust assembly 30. A threaded hole 49 is provided at the center of the top bracket 37. The adjusting screw 38 and the threaded hole 49 are threadedly connected. A flat plate portion 50 is provided at the bottom of the adjusting screw 38, and one end of the pressure control spring 39 is provided on the flat plate portion 50.

[0057] The exhaust assembly 30 includes a valve cylinder 40, a valve seat 41 and a spherical valve plug 42. The valve cylinder 40 is clamped in the top cover plate 51, the valve seat 41 is clamped in the valve cylinder 40, the spherical valve plug 42 is located in the valve seat 41, and the other end of the pressure control spring 39 is arranged on the spherical valve plug 42.

[0058] The air pressure in the water tank 33 can be maintained within a certain range through the exhaust component 30, and excess gas can be discharged through the exhaust component 30, but the powder sprayed from the elbow 26 will remain in the water. Moreover, by rotating the adjusting screw 38, the pre-compression amount and pre-pressure of the longitudinal and transverse pressure control springs 39 can also be increased, thereby changing the opening threshold of the spherical valve plug 42, and then adjusting the air pressure in the water tank 33.

[0059] The blower type multi-media collection mechanism 2 includes a blower impeller 20, an air collecting hood 21 and an air collecting pipe 22. The blower impeller 20 is composed of a base ring portion 23 and an annularly evenly distributed blade portion 24. The blade portion 24 is fixedly connected to the outer side of the base ring portion 23. The blower impeller 20 is fixedly connected to the outer wall of the grinding disc 13 through the base ring portion 23.

[0060] The blower impeller 20 can rotate along with the grinding disc 13 during the grinding process, so that the directional flow of air can be adaptively achieved by utilizing the driving force of the grinding itself without an active drive control module; not only that, the size of the blowing power can also increase with the increase of the grinding speed, thereby realizing automatic regulation of the blowing power.

[0061] The air collecting hood 21 is arranged outside the motor mounting plate 7 , and a joint part 25 is provided on the air collecting hood 21 . One end of the air collecting pipe 22 is connected to each joint part 25 , and the other end of the air collecting pipe 22 is arranged in the automatic constant pressure water supply mechanism 3 .

[0062] The powder produced by grinding can be collected through the air collecting pipe 22 and sprayed into the water in the water storage tank 33 through the elbow 26, thereby achieving the technical purpose of collecting powder and reducing air pollution.

[0063] When in use, the user first needs to place the water tank 33 on a flat open space near the grinding area, then hold the motor housing 10 to press the detachable grinding wheel 14 on the object to be ground, and then start the drive motor 8, so that the output shaft 16 and the square shaft portion 17 rotate the pre-tightening sleeve 11 to rotate the grinding disc 13 and the detachable grinding wheel 14, and the surface of the object is ground by the high-speed relative rotation between the detachable grinding wheel 14 and the object;

[0064] During the grinding process, a large amount of powder will fall off the object. However, since the outside of the detachable grinding wheel 14 is provided with a closed chamber composed of a push-type water control component 27, the powder of the push-type pre-tightening grinding mechanism 1 will generally not leak out when it is not moving. When the grinding wheel 13 rotates at high speed, it will also rotate with the blower impeller 20. When the blade part 24 rotates, it will generate a directional airflow to supply the powder ground by the detachable grinding wheel 14 into the water storage tank 33 through the air collecting pipe 22. Since the inside of the water dividing baffle 31 is not a closed chamber, this airflow can be continuously generated.

[0065] The gas carrying the powder is ejected from the elbow 26, wherein the powder enters the water, and the air floats out of the water in the form of bubbles. In the initial state, the ball valve plug 42 completely blocks the valve seat 41. When the air pressure in the water storage tank 33 increases to a level sufficient to overcome the elastic force of the pressure control spring 39, the ball valve plug 42 is pushed open to release the pressure. When the air pressure drops to the set value, the ball valve plug 42 is closed again, thereby maintaining the air pressure in the water storage tank 33 stable.

[0066] The mesh plate 35 can allow the powder to fall below itself and the horizontal plate portion 48, and the water flow below the horizontal plate portion 48 is relatively flat, and the water-insoluble powder will settle at the bottom in the water storage tank 33;

[0067] Since the air pressure in the water tank 33 is higher than the external atmospheric pressure, the water in the water tank 33 will enter the water distribution pipe 43 through the constant pressure water supply pipe 36 under the action of the air pressure, and contact the sponge ring 32 along the down pipe 45. When the water inside the sponge ring 32 is sufficient, the flow of water will be suspended, and when the water inside the sponge ring 32 is less, the flow of water will continue.

[0068] The ground powder can be extracted with the negative pressure generated by the air-blast multi-media collecting mechanism 2, but in actual operation, some powder cannot be extracted. After being sticky with water, this part of the powder will adhere to the surface of the object and will not diffuse into the air.

[0069] By pressing the motor mounting plate 7, the compression and relaxation states of the sponge ring 32 can be switched, thereby achieving the technical effect of manually controlling the amount of water output.

[0070] By rotating the adjusting screw 38 , the pre-compression amount and pre-tightening force of the pressure control spring 39 can be changed, thereby adjusting the air pressure in the water tank 33 .

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
