The specific embodiment
Embodiments of the invention are described below with reference to accompanying drawings.Fig. 1 and Fig. 2 show the embodiment of a dust pelletizing system of the present invention, this dust pelletizing system has a dust removal head 1, an air-blast device (not shown) and a mobile device (not shown), when workpiece 2 is set near this dust removal head 1, this mobile device will make workpiece 2 move to the direction of arrow A.
Specifically, it is long shell 7 that dust removal head 1 has a width along workpiece 2, has formed suitable with the longitudinal length of the shell 7 basically air suction chamber 4 of its size in shell 7 inside.At the downside of shell 7, form slot-shaped air suction inlet 3 (see figure 2)s of its longitudinal length L greater than the width W a of workpiece 2.
Do not have an end of an air suction passage illustrated in the accompanying drawings to be connected with air suction chamber 4, an air-blast device that is used for the air in the suction air suction chamber 4 is connected with the other end of this air suction passage.By the suction force of air-blast device, the air in air suction chamber 4 just is inhaled in the air-blast device by the air suction passage, and this system's air outside is inhaled in the air suction chamber 4 by the space between air suction inlet 3 and workpiece 2.
As shown in fig. 1, the brush roll 5 of rotating be configured to axle M that slot-shaped air suction inlet 3 in the air suction chamber 4 of shell 7 parallels on rotate, brush roll 5 is driven by unshowned device of rotation driving in the accompanying drawing and along the direction rotation of the arrow F among Fig. 1.By rotating brush roller 5, stick to workpiece 2 lip-deep dust R and just wiped.
As the situation of the present invention of above-mentioned structure under, when air from the hole, slit 10 of nozzle 6 when arrow C is sucked out, concave part 20 air all around that is centered around the end of nozzle 6 flows downward along concave part 20 with very high speed, shown in the dotted line among Fig. 3, and this air reaches a dark slightly position of bristle 12 before in being inhaled into hole, slit 10.So the dust R that sticks on the bristle 12 of brush roll 5 of rotation just can be disposed fully.
Below, returning referring again to Fig. 1, the diameter D of the brush roll 5 of rotation is set to the relation of the inner width W of the air suction chamber 4 of the moving direction that is parallel to workpiece 2: D≤W≤(D+20 millimeter).Therefore, space between the inner wall surface of brush roll 5 of rotating and air suction chamber 4 can be littler, air in air suction chamber 4 inside just can be with flow at high speed, the dust R that is inhaled into thus in the air suction chamber 4 just can flow in the air suction passage fast, and can prevent that dust R from staying in the air suction chamber 4, thereby just can prevent that also dust R from sticking on the workpiece 2 again.
Preferably, the relation of diameter D and inner width W is set to: (D+3 millimeter)≤W≤(D+10 millimeter), under the air of air suction chamber 4 inside just can be than the situation that is set at D≤W≤(D+20 millimeter), flow like this, thereby can stop dust R to stay possibility in the air suction chamber 4 with more steady and higher speed.If D＞W, brush roll 5 will contact with the inner wall surface of air suction chamber 4, does not just have the space between the inner wall surface of brush roll 5 and air suction chamber 4.Thereby the speed air flow in air suction chamber 4 will reduce greatly and the ability of the suction dust R of dust removal head 1 also will reduce.If W＞(D+20 millimeter), the space between the internal face of brush roll 5 and air suction chamber 4 just becomes too big, and the speed air flow in air suction chamber 4 also will reduce.
Air flows through between partition wall 11 that forms air suction inlet (3) and workpiece 2 with the speed of 50-60 meter per second.Dust R just can more effectively be eliminated from the workpiece and one be inhaled into surely in the air suction chamber 4 like this.In addition, the material behavior owing to workpiece 2 that sticks on the workpiece 2 is difficult to by conventional dust pelletizing system its dust R that peels off can be removed it with dust pelletizing system of the present invention in some cases.When speed air flow V being set at 50 meter per seconds when following, the dust R under being swept by brush roll 5 may go to the system outside by the space between the surface of partition wall 11 and workpiece 2.Even the flowing velocity of air is higher than 60 meter per seconds, the elimination efficiency of dust R does not have much variations yet.
The range of speeds of the brush roll 5 of rotating is set in 1600 to 3000 rev/mins.Sticking to dust R on the workpiece 2 like this can be removed effectively and can stop workpiece 2 by the possibility of brush roll scratch.If the rotating speed of brush roll 5 is lower than 1600 rev/mins, the dust R that sticks to securely in some cases on the workpiece 2 may not be removed.If the rotating speed of brush roll 5 is higher than 3000 rev/mins, the surface of workpiece 2 just may be by brush roll 5 scratches or damage.
As shown in Figure 4, can be set to the relation of the thickness T of the length B of the bristle end portion 12a of the bristle 12 of the surperficial contacted described rotating brush roller 5 of workpiece 2 and described workpiece 2: 0≤B≤T.Like this when the work of this dust pelletizing system, as shown in Figure 5, each bristle end portion 12a can and moderately store under the situation of elastic energy and slide on the surface of workpiece 2 really at bristle 12 slight curvatures.For this reason, stick to that dust on the workpiece 2 can be eliminated more beyond the question and workpiece can not sustain damage.If bristle end portion 12a is set to 0＞B, if promptly bristle end portion 12a is configured to not contact with the surface of workpiece 2, brush roll 5 will not have the function of dust out.If B＞T, bristle 12 gets bending too big and will seriously impact the also surface of scratch workpiece 2.
As top illustrated the present invention, the brush roll 5 that sticks to the rotation that dust R on the workpiece 2 can be by dust pelletizing system of the present invention is disposed surely He efficiently.In addition, the dust R that sticks on the brush roll 5 can remove by using nozzle 6, and the possibility that is sticked to once more on the workpiece 2 by the dust R that removes from workpiece 2 also is prevented from.Particularly, the dust that for example is clamminess, be trapped in fine hair on the end edge of dust on the workpiece 2 and workpiece 2 (at workpiece 2 under the situation of paper) and can be effectively disposed.
The dust removal head 1 that can prevent this dust pelletizing system becomes dirty.In other words, space between the inner wall surface of rotating brush roller 5 and air suction chamber 4 can be less than this space in the conventional dust pelletizing system, and the air in air suction chamber 4 can promptly flow in the air suction passage with flow at high speed and the dust R that is inhaled in the air suction chamber 4.After this dust pelletizing system work, just can stop dust R to stay in the air suction chamber 4 like this.In other words, dust R can not be stayed on the inner wall surface of rotating brush roller 5 and air suction chamber 4.Therefore, dust removal head 1 can use for a long time and not need to clean, thereby can reduce the number of times that cleans and change brush roll 5.Thereby this dust pelletizing system while easy to maintenance operating cost is reduced.
Below, an alternative embodiment of the invention has been shown among Fig. 6.This dust pelletizing system has the upstream side H of the air suction inlet 3 that is arranged on air suction chamber 4 and first and second discharge sides 15,16 at downstream J place, and being provided with first and second superonic flow nozzzles 13,14, those nozzles are used for respectively air is changed into the air knife K that comprises supersonic speed pressure wave P and this air knife K is blowed to described workpiece 2.
Has the air of coming in by unshowned air discharging channel the accompanying drawing in the first and second air discharge sides 15,16 from a unshowned air-blast device of accompanying drawing.This air is by first and second superonic flow nozzzles 13,14 and become and comprise supersonic speed pressure wave P and impact air knife K on workpiece 2.After air knife K was inhaled in the air suction chamber 4 with dust R, this air just returned in the described air-blast device by an air suction passage.
Referring to Fig. 8, when be arranged with the air that blows out at a high speed when air discharge side 201 blows to the surface of workpiece 2 and be inhaled into the air suction chamber 203, part dust R separates from the surface of workpiece 2 by a kind of air knife effect of so-called air-flow, yet on the surface of workpiece 2, also formed the boundary layer 25 that air flows with low speed, most of dust R is closed in the described boundary layer 25, therefore dust R is removed from workpiece 2 and has produced difficulty.
Use dust pelletizing system of the present invention as shown in Figure 7, supersonic speed pressure wave P can destroy boundary layer 25, and air knife K can directly impact the surface of workpiece 2, thereby dust R can be peeled off effectively.Brush roll 5 and the two kinds of dedusting effects of air knife K that comprise supersonic speed pressure wave P are so just arranged, and the dust R that sticks on the workpiece 2 just can be disposed more surely.Particularly, for example can be with the dust that is clamminess, be trapped in fine hair on the end edge of dust on the workpiece 2 and workpiece 2 (at workpiece 2 under the situation of paper) and can be disposed effectively.
Fig. 9 shows another embodiment of the present invention.This dust pelletizing system has the air suction chamber 17 of a downstream J who is arranged on air suction chamber 4 and first and second air that are arranged on the downstream J of described air suction chamber 4 and the first and second supersonic speed dirt nozzles 13,14 are housed are discharged chamber 15,16, and this nozzle impacts the air knife K that comprises the supersonic speed pressure wave on the workpiece 2 of the upstream side H of described air suction chamber 17 and downstream J.
Therefore, be provided with air suction chamber 4, have the air suction chamber 17 of the air suction inlet of opening in the downstream of air suction chamber 4 19, the connected chamber 18 that is being communicated with air suction chamber 4 and 17 and the described first and second air discharge sides 15 and 16 downwards in the inside of the shell 7 of dust removal head 1.The remaining parts of this embodiment is identical with shown in Fig. 1-7 almost.
The present invention as above-mentioned structure, brush roll 5 in air suction chamber 4 is bonded at the upstream side H place of air suction chamber 4 after dust R on the workpiece 2 peels off, and the air knife K that comprises supersonic speed pressure wave P that blows out from first and second ultrasonic nozzles 13,14 of the downstream J of air suction chamber 4 just can carry out aspirating powerfully and removing to left dust R on workpiece 2.The dust R that sticks on the workpiece 2 is eliminated by two step dedusting operations, brush roll that Here it is 5 and in the running of the air knife K that comprises supersonic speed pressure wave P in the downstream of air suction chamber 4.By these two dedusting operation steps, can dust be removed more surely.
Figure 10 shows another embodiment of the present invention.Shell 7 has partition wall 11, the scraper plate blade that wherein has the triangular-section divides 30 to be formed obliquely on the lower edge of this wall (as shown in Figure 10), thereby the gap between the outer circumference surface of the lower edge (being that the scraper plate blade divides 20) of partition wall 11 and brush roll 5 has been reduced.Like this, the speed of the air-flow in the gap between the outer circumference surface of the lower edge (being that the scraper plate blade divides 30) of partition wall 11 and brush roll 5 has just increased, and the micronic dust R that separates from workpiece 2 surfaces also must be inhaled into the air suction chamber 4.
