preferably, described through hole is triangular in shape.
preferably, described transition guide plate comprises body, and described body extends to form downward-sloping edge part to the direction near abrasive belt grinding device, and described through hole is arranged on the intersection of described edge part and described body.
the utility model also provides a kind of dust exhaust apparatus, and described dust exhaust apparatus comprises above-mentioned transition guide plate, and described dust exhaust apparatus also comprises and being arranged on the downside of described transition guide plate for the wind-supplying mouth to described through hole delivery air.
preferably, described dust exhaust apparatus also comprises dust absorption passage, and described dust absorption passage is arranged on the side near described abrasive belt grinding device, and described dust absorption passage has the suction port being positioned at upside.
preferably, described dust exhaust apparatus also comprises one and is arranged on the inclined wall playing guide functions for the air-flow entered described wind-supplying mouth on the downside of transition guide plate, the incline direction of described inclined wall is from top to bottom gradually away from described abrasive belt grinding device, the air-flow entered from described wind-supplying mouth travels up to through hole along described inclined wall, to make the air-flow flowed out from described through hole be towards the direction of described abrasive belt grinding device.
the utility model also provides a kind of sander, and described sander comprises above-mentioned dust exhaust apparatus, and described sander also comprises an abrasive belt grinding device, and described abrasive belt grinding device upper end opposite piece rotates to the side of dust exhaust apparatus.
due to the enforcement of above technical scheme, the utility model compared with prior art tool has the following advantages:
through hole offered by described sander of the present utility model on transition guide plate, can be cleaned, make residual dust on work plate face enter dust absorption passage with this air-flow, serve the effect in effective cleaner plate face by the workpiece of through hole to pre-polishing.On the other hand, dust exhaust apparatus described in the utility model to make dust granules be mixed into blow in the air-flow in abrasive band and obtains the method for the initial velocity identical with air velocity, and this method makes air-flow to the clean effect with " sandblasting is cleaned " in abrasive band and plate face.
Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in more detail.
fig. 1 is the structural representation of dust exhaust apparatus described in the utility model;
fig. 2 is the perspective view of dust exhaust apparatus described in the utility model;
wherein: 1, workpiece; 2, abrasive belt grinding device; 3, dust exhaust apparatus; 4, transition guide plate; 5, suction port; 6, wind-supplying mouth; 7, dust suction district; 8, through hole.
Detailed description of the invention
as shown in Figure 1, sander described in the utility model comprises transition guide plate 4, before described transition guide plate 4 is arranged on the abrasive belt grinding device 2 of sander, for playing guide support effect to grinding workpiece 1, described abrasive belt grinding device 2 upper end opposite piece 1 rotates to the side of dust exhaust apparatus 3.Described transition guide plate 4 surface offers multiple through hole 8.Can be cleaned by the workpiece 1 of through hole 8 to pre-polishing, make residual dust on workpiece 1 plate face enter dust absorption passage with this air-flow, serve the effect in effective cleaner plate face.
the position of device is worn down in the close abrasive band that described multiple through holes 8 are opened in described transition guide plate 4, and the arragement direction of described multiple through holes 8 on described transition guide plate 4 is vertical with the direct of travel of workpiece 1.Preferably, described through hole 8 is triangular in shape.Described transition guide plate 4 comprises body, and described body extends to form downward-sloping edge part to the direction near abrasive belt grinding device 2, and described through hole 8 is arranged on the intersection of described edge part and described body.Described dust exhaust apparatus 3 also comprises and being arranged on for the wind-supplying mouth to described through hole 8 delivery air on the downside of described transition guide plate 4, and described wind-supplying mouth is connected with described through hole 8.Raise the position of wind-supplying mouth in the utility model, increase suction inlet region, after increasing suction inlet region, dust concentration reduces, thus increases dust collection efficiency.
described dust exhaust apparatus 3 also comprises dust absorption passage, and described dust absorption passage is arranged on the side near described abrasive belt grinding device 2, and described dust absorption passage has the suction port 5 being positioned at upside.The air-flow entering wind-supplying mouth, through air vent inswept workpiece 1 plate face, enters dust absorption passage after making workpiece 1 plate face residual dust enter dust suction district 7 with this air-flow, serves the effect in effective cleaner plate face.On the other hand, dust granules to be mixed in the air-flow blowing to abrasive band and to obtain the method for the initial velocity identical with air velocity, and this method makes air-flow to the clean effect with " sandblasting is cleaned " in abrasive band and workpiece 1 plate face.
