[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] See also Figures 1 to 9 A metal polishing machine with a dust handling function provided by an embodiment of the present invention includes a base frame 1 and a polishing work box 2. A conveying structure 3 passing through the interior of the polishing work box 2 is installed on the base frame 1. A grinding belt 4 is installed inside the polishing work box 2. It also includes a grinding belt cleaning mechanism 5 and a conveyor belt cleaning mechanism 6.

[0039] It should be noted that: a conveying structure 3 is provided on the base frame 1, and the workpiece to be processed can be directly placed on the conveying structure 3, and the conveying structure 3 passes through the polishing operation box 2, so that the workpiece can be transferred to the polishing operation box 2, and then the workpiece is ground by the grinding belt 4 inside the polishing operation box 2 to achieve polishing of the workpiece;

[0040] The grinding belt cleaning mechanism 5 and the conveyor belt cleaning mechanism 6 are used to clean the grinding belt 4 and the conveyor belt 32 respectively. In actual use, the grinding belt cleaning mechanism 5 is first used to clean the waste on the grinding belt 4, and the cleaned waste will fall onto the conveyor belt 32, and then the conveyor belt cleaning mechanism 6 is used to centrally clean the waste on the conveyor belt 32;

[0041] The grinding belt 4 is a traditional grinding structure, which is positioned and driven by an axis and a supporting wheel. The grinding belt 4 can be raised and lowered according to the thickness of the workpiece. The raising and lowering adjustment of the grinding belt 4 is a prior art, so it is not described in detail here.

[0042] For the conveying structure 3 and the grinding belt 4;

[0043] See also Figure 3 and Figure 4 The conveying structure 3 includes two plate frames 31 fixed to the base frame 1 by bolts, a conveyor belt 32 and a conveyor roller 33 are installed on the plate frame 31, the plate frame 31 passes through the interior of the polishing operation box 2, and the conveyor roller 33 is located at the unloading end of the conveyor belt 32 and extends to the outside of the polishing operation box 2;

[0044] The grinding belt 4 is Z-shaped and has two belt bodies which are distributed vertically and arranged horizontally. The belt body located at the bottom can contact the workpiece to be processed and grind the workpiece, while the belt body located at the top can contact the grinding belt cleaning mechanism 5.

[0045] It should be noted that: with respect to the conveying structure 3, it includes a section of conveyor belt 32 and a section of conveyor roller 33. In actual use, the workpiece is first placed on the conveyor belt 32, and then the workpiece is transferred to the inside of the polishing operation box 2 through the conveyor belt 32. When it moves to the position below the grinding belt 4, the height of the grinding belt 4 is adjusted so that it contacts the workpiece, and then the workpiece is polished by the rotation of the grinding belt 4. After the grinding operation on the workpiece is completed, the workpiece is transferred to the conveyor roller 33 through the conveyor belt 32. The conveyor roller 33 extends to the outside of the polishing operation box 2, so that the completely processed workpiece can be transported to the outside of the polishing operation box 2, which is convenient for the unloading of the workpiece, and the waste chips on the conveyor belt 32 can fall directly when they move to the unloading end position, so as to facilitate the cleaning of the conveyor belt cleaning mechanism 6;

[0046] The grinding belt 4 itself is Z-shaped and has two horizontal belt bodies. The belt body located at the bottom can contact the workpiece for grinding the workpiece, while the belt body located at the top can better cooperate with the grinding belt cleaning mechanism 5 to clean the grinding belt 4.

[0047] For the grinding belt cleaning mechanism 5;

[0048] See also Figure 4 and Figure 5 The grinding belt cleaning mechanism 5 includes a first rotating shaft 51 rotatably connected to the inside of the polishing operation box 2, a brush roller 52 is fixed on the first rotating shaft 51, the brush roller 52 is in contact with the grinding belt 4, and the brush roller 52 and the grinding belt 4 rotate in opposite directions;

[0049] A driving gear 53 is keyed to the first rotating shaft 51 ; and a driven gear 54 is keyed to the shaft for driving the grinding belt 4 to rotate, and the driven gear 54 and the driving gear 53 are meshed for transmission.

[0050] It should be noted that when the grinding belt cleaning mechanism 5 is actually used, the rotation of the grinding belt 4 drives the driving gear 53 to rotate, and then drives the driven gear 54 and the first rotating shaft 51 to rotate. The brush roller 52 is mobilized to rotate through the first rotating shaft 51. The brush roller 52 is in direct contact with the grinding belt 4. During the rotation process, the grinding belt 4 can be cleaned to remove waste chips attached to the grinding belt 4, thereby cleaning the grinding belt 4 (the diameters of the driving gear 53 and the driven gear 54 need to be different, so that there is a speed difference between the grinding belt 4 and the brush roller 52. When there is a speed difference, mutual friction can be generated between the brush roller 52 and the grinding belt 4, thereby cleaning the grinding belt 4).

[0051] See also Figure 6 Two groups of symmetrically arranged tripods 55 are bolted to the polishing work box 2, and a horizontally arranged fixing rod 56 is interspersed and fixed between the two groups of tripods 55. A plurality of sleeves 57 are sleeved on the fixing rod 56. A film 58 is screwed to the outside of any sleeve 57, and the plurality of films 58 form a rubber curtain for intercepting the waste scraps swept down by the brush roller 52.

[0052] It should be noted that when the grinding belt 4 is cleaned by the brush roller 52, the swept waste chips will splash. In this regard, a plurality of films 58 are arranged beside the brush roller 52. The plurality of films 58 form a rubber curtain, and the rubber curtain is used to intercept the splashed waste chips. The film 58 itself is made of rubber material, which has a certain buffering effect on the splashed waste chips. The intercepted waste chips will fall onto the conveyor belt 32 and then be transferred through the conveyor belt 32.

[0053] For the conveyor belt cleaning mechanism 6;

[0054] See also Figure 7 and Figure 8 The conveyor belt cleaning mechanism 6 includes a waste collecting bucket 61, which is screwed to the plate frame 31. The upper end of the waste collecting bucket 61 has an opening, which corresponds to the connection position between the conveyor belt 32 and the conveyor roller 33. The lower end of the waste collecting bucket 61 is flange-connected with a first guide pipe 62, and the other end of the first guide pipe 62 is flange-connected with a valve pipe 63;

[0055] A second flow guide pipe 64 is welded to the circumferential outer wall of the first flow guide pipe 62. One end of the second flow guide pipe 64 is also penetrated into the first flow guide pipe 62 and a filter screen 66 is welded to the end. The filter screen 66 is hemispherical with the convex surface facing the axis of the first flow guide pipe 62. A fan 65 is bolted to the other end of the second flow guide pipe 64.

[0056] It should be noted that when the conveyor belt cleaning mechanism 6 is actually used, the fan 65 is first turned on, and then negative pressure is formed at the opening of the waste collecting bucket 61. The waste collecting bucket 61 itself is at the connection position between the conveyor belt 32 and the conveyor roller 33. Therefore, the waste accumulated on the conveyor belt 32 will directly fall into the waste collecting bucket 61. At the same time, the waste attached to the conveyor belt 32 will also enter the waste collecting bucket 61 under the adsorption of negative pressure, and then enter the first guide pipe 62. The lower end of the first guide pipe 62 has a valve pipe 63. When the valve pipe 63 is closed, the waste is concentrated in the first guide pipe 62. When the valve pipe 63 is opened, the waste can be discharged to achieve the cleaning of the waste.

[0057] The second flow guide pipe 64 is connected to the first flow guide pipe 62 and is used to install the fan 65 . The other end of the second flow guide pipe 64 has a filter screen 66 , which can intercept waste chips and concentrate them inside the first flow guide pipe 62 .

[0058] See also Figure 8 and Fig. 9 The outer circumferential wall of the first flow guide tube 62 is also welded with an extension tube 67 symmetrically arranged with the second flow guide tube 64. The other end of the extension tube 67 is threadedly connected with a cover 68. The cover 68 is penetrated by a second rotating shaft 69 that is rotatably connected. One end of the second rotating shaft 69 is welded with a turning handle 610 located outside the extension tube 67. The other end of the second rotating shaft 69 extends to the inside of the first flow guide tube 62 and is welded with a plurality of annularly distributed brush plates 611. The brush plates 611 contact the outer convex surface of the filter screen 66.

[0059] A positioning ring 612 is welded to the other end of the plurality of brush plates 611 . The positioning ring 612 is concentrically sleeved on the outside of the second guide tube 64 . A plurality of balls are embedded in the circumferential inner wall of the positioning ring 612 . The balls roll on the outer wall of the second guide tube 64 .

[0060] It should be noted that: the extension tube 67 has a second rotating shaft 69 inside, and a handle 610 is fixed at one end of the second rotating shaft 69. When the handle 610 is rotated, it can drive the second rotating shaft 69 to rotate. The other end of the second rotating shaft 69 has a plurality of brush plates 611. The brush plates 611 are in contact with the outer convex surface of the filter screen 66. Therefore, when the brush plates 611 rotate, the waste on the filter screen 66 can be cleaned to ensure the unobstructed flow of the filter screen 66.

[0061] The positioning ring 612 is fixed to the brush plate 611 and is connected to the second flow guide tube 64 via a ball rolling mechanism, so it has a positioning and supporting function for the brush plate 611, thereby making the brush plate 611 more stable.

[0062] The specific usage process of the device is as follows:

[0063] (1) Loading, unloading and grinding of workpieces;

[0064] First, the workpiece to be processed is placed on the conveyor belt 32, and the workpiece is conveyed to the inside of the polishing operation box 2 by the conveyor belt 32. When the workpiece moves to the position directly below the grinding belt 4, the grinding belt 4 is controlled to move downward so that the grinding belt 4 contacts the workpiece, and then the workpiece is ground. After the grinding operation is completed, the workpiece is transferred to the conveyor roller 33 by the conveyor belt 32, and then unloaded by the conveyor roller 33;

[0065] (2) Cleaning of grinding belt;

[0066] When the grinding belt cleaning mechanism 5 is actually used, the rotation of the grinding belt 4 drives the driving gear 53 to rotate, and then drives the driven gear 54 and the first rotating shaft 51 to rotate. The brush roller 52 is adjusted to rotate through the first rotating shaft 51. The brush roller 52 directly contacts the grinding belt 4 and can clean the grinding belt 4 during the rotation process to remove the waste chips attached to the grinding belt 4, thereby cleaning the grinding belt 4.

[0067] (3) Cleaning of conveyor belt;

[0068] When the conveyor belt cleaning mechanism 6 is actually used, the fan 65 is first turned on, and then a negative pressure is formed at the opening of the waste collecting bucket 61. The waste collecting bucket 61 itself is at the connection position between the conveyor belt 32 and the conveyor roller 33. Therefore, the waste debris accumulated on the conveyor belt 32 will directly fall into the waste collecting bucket 61. At the same time, the waste debris attached to the conveyor belt 32 will also enter the waste collecting bucket 61 under the adsorption of negative pressure, and then enter the first guide tube 62. The lower end of the first guide tube 62 has a valve tube 63. When the valve tube 63 is closed, the waste debris is concentrated in the first guide tube 62. When the valve tube 63 is opened, the waste debris can be discharged to achieve the cleaning of the waste debris.

[0069] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
