[0022] As Figure 1 , Figure 2 and Figure 3As shown, the self-cleaning burr removing machine provided by the embodiment of the present application comprises a rack 1, a conveying mechanism 4 arranged on the rack 1, a sand belt burr removing mechanism 2 and a roller brush mechanism 3 arranged on the rack 1 in sequence along the conveying direction of the conveying mechanism 4, the conveying mechanism 4 comprises a vacuum extraction assembly 41, a gas blowing assembly 42, a frame 43, a first plate 44 arranged on the upper end of the frame 43, a driving roller 45 arranged on one end of the frame 43, a driven roller 46 arranged on the other end of the frame 43, a conveying belt 48 arranged on the driving roller 45 and the driven roller 46, a first motor 47 arranged on the frame 43 for driving the driving roller 45 to rotate, the first plate 44 and the frame 43 form a cavity, the cavity is located in the annular area of the conveying belt 48, the conveying belt 48 is provided with a second hole 480, the first plate 44 is provided with a plurality of first holes 440 in communication with the cavity, and a plurality of grooves 40 are alternately arranged on the lower end surface of the cavity, the frame 43 is provided with a first air port 431 corresponding to the lower end of the groove 40 and a second air port 432 corresponding to the upper end of the groove 40, the vacuum extraction assembly 41 is in communication with the cavity through the first air port 431, and the gas blowing assembly 42 is in communication with the cavity through the second air port 432.

[0023] In actual use, the first motor 47 drives the driving roller 45 to rotate, and the transmission of the conveying belt 48 is realized under the cooperation of the driven roller 46, and the metal part is conveyed on the conveying belt 48. When the metal part is conveyed to the corresponding working area of the sand belt burr removing mechanism 2, the metal part is deburred, and when the metal part is conveyed to the corresponding working area of the roller brush mechanism 3, the metal part is polished by the roller brush, and the residual burr is further removed. In the process of deburring the metal part, the removed burr forms metal scraps, the metal scraps enter the cavity through the second hole 480 along the first hole 440, most of the metal scraps in the cavity are extracted out of the cavity by the vacuum extraction assembly 41 after entering the cavity, and the residual metal scraps in the cavity are blown out of the first air port 431 by the gas flow blown by the gas blowing assembly 42 along the second air port 432 to the first air port 431.

[0024] In the above design, the structure design of the cavity and the gas blowing assembly 42 can effectively remove the metal scraps in the cavity, ensure the cleanliness inside the cavity, and improve the efficiency of cleaning the cavity.

[0025] Specifically, as shown in the drawings, Figure 4 As shown, the groove 40 comprises an inclined bottom surface 401 and side surfaces 402 symmetrically arranged on both sides of the bottom surface 401, and the length of the upper end of the bottom surface 401 is greater than the length of the lower end of the bottom surface 401.

[0026] In actual use, part of the metal scraps flow along the upper end of the bottom surface 401 to the lower end of the bottom surface 401.

[0027] In the above design, the structural design and specific implementation of the slide 40 facilitate the reduction of the resistance when the vacuum assembly 41 adsorbs metal debris in the cavity.

[0028] Specifically: such as Figure 4 As shown, the two sides of the lower end of the bottom surface 401 correspond to the two sides of the first air outlet 431, and the upper end of the same bottom surface 401 corresponds to at least two second air outlets 432. The air blowing assembly 42 includes several air pipes connected to the second air outlets 432 and an air pump for supplying air to the air pipes.

[0029] In actual use, the upper part of the bottom surface 401 is blown by the airflow from multiple air pipes, and the metal debris in the same chute 40 only enters the corresponding No. 1 air outlet 431.

[0030] In the above design, by setting multiple No. 2 air outlets 432, the air pressure of each No. 2 air outlet 432 is maximized, which facilitates the blowing of metal debris attached to the slide 40. The No. 1 air outlet 431 is set to maximize the extraction of metal debris in the same slide 40.

[0031] Specifically: such as Figure 5 As shown, the frame 1 includes a frame body 11 and a lifting mechanism 12 mounted on the frame body 11 for raising and lowering the conveying mechanism 4. The sanding belt deburring mechanism 2 and the roller brush mechanism 3 are mounted on the frame body 11. Figure 6 and Figure 7 As shown, the lifting mechanism 12 includes four lifting support legs 121 that are vertically fixed on the frame 11 to support the four corners of the frame 43, driven sprockets 122 coaxially disposed at the lower end of the lifting support legs 121, chains 124 meshing with several driven sprockets 122, and a drive assembly disposed on the frame 11 to drive the chain 124. The lifting support legs 121 include guide sleeves 1201 fixedly disposed on the frame 11, guide posts 1202 slidably disposed on the guide sleeves 1201, and fixedly disposed... The guide sleeve 1201 has a bearing housing 1203 at the lower end, a ball bearing 1204 disposed in the bearing housing 1203, and a lead screw 1205 fixedly connected to the inner ring of the ball bearing 1204. The upper end face of the guide post 1202 is provided with a first screw hole 2020, and the lower end face of the guide post 1202 is provided with a second screw hole that is threadedly connected to the lead screw 1205. The drive assembly includes a second motor 123 fixedly disposed on the frame 11 and a drive sprocket disposed at the output end of the second motor 123. The drive sprocket meshes with the chain 124.

[0032] In actual use, the frame 43 is connected with the guide column 1202 by connecting the external bolt with the first screw hole 2020. The frame 43 is driven to ascend and descend by the lifting mechanism 12, so as to realize the lifting of the whole conveying mechanism 4. The working principle of the lifting mechanism 12 is that the driving sprocket is driven to rotate by the second motor 123, the driving sprocket drives the driven sprocket 122 at the lower end of each lifting support leg 121 to rotate, and the driven sprocket 122 drives the screw rod 1205 to rotate, so that the screw rod 1205 drives the guide column 1202 to ascend and descend through the screwing in the second screw hole.

[0033] In the above design, the structural design and specific implementation of the rack 1 and the lifting mechanism 12 can effectively realize the lifting of the conveying mechanism 4, and facilitate the machining of sheet metal with different thicknesses.

[0034] Specifically, as shown in Figure 6 and Figure 7 , the frame body 11 is further provided with a tensioning assembly 125 for tensioning the chain 124, the tensioning assembly 125 includes a bolt and nut assembly, a seat body 1251 provided on the frame body 11 and horizontally provided with a waist-shaped groove 510, a second plate 1252, a rotating shaft 1253 provided on the second plate 1252, and a tensioning sprocket 1254 provided on the rotating shaft 1253, the second plate 1252 is provided with a third screw hole for cooperating with the waist-shaped groove 510, and the bolt and nut assembly is connected with the second plate 1252 and the seat body 1251 through the third screw hole and the waist-shaped groove 510.

[0035] In actual use, the tensioning degree of the tensioning sprocket 1254 on the chain 124 is changed by adjusting the different positions of the third screw hole and the waist-shaped groove 510.

[0036] In the above design, the structural design and specific implementation of the tensioning assembly 125 facilitate the tensioning of the sprocket and the assembly of the whole lifting mechanism 12.

[0037] It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
