[0017] See also Figure 1-4 The utility model relates to a dust collection device for a velvet cutting machine, comprising a housing 1, an annular cutter 2, a cutting plate 3 and a pressing blade 4. The annular cutter 2 is wound around two rotating rollers, one of which is driven by a motor to drive the annular cutter 2 to rotate. The cutting plate 3 and the pressing blade 4 clamp the annular cutter 2. The cutting plate 3 and the pressing blade 4 are fixed to the housing 1. The cutting plate 3 is used to fix and support the annular cutter 2. The blade of the annular cutter 2 faces horizontally forward. Multiple cutting plates are arranged at intervals, and the cutting plates 3 and the pressing blade 4 are staggered to leave a channel for the discharge of dust.

[0018] A plurality of air inlet holes 5 are provided on the side of the top of the box body 1 away from the blade of the annular cutting knife 2, and the plurality of air inlet holes 5 are spaced apart in the width direction of the flannel. The interior of the box body 1 is hollow, and a plurality of air outlet holes 6 are provided at the bottom of the box body 1. The number of the air outlet holes 6 is less than the air inlet holes 5, and the aperture of the air outlet holes 6 is larger than the aperture of the air inlet holes 5. The air outlet holes 6 are connected to the dust collecting box 8 through the dust removal pipe 7. An air inlet 9 and an air outlet 10 are provided on the wall of the dust collecting box 8. The air inlet 10 is connected to the dust removal pipe 7, and the air outlet 10 is connected to the suction fan.

[0019] A filter 11 and a brush 12 are provided in the dust box 8. The filter 11 is arranged vertically, and the air inlet 9 and the air outlet 10 are respectively arranged on both sides of the filter 11. The brush 12 is rotatably arranged on the air inlet side. The brush 12 is driven to rotate by a drive motor 13, and the drive motor 13 is arranged on the air outlet side. The drive motor 13 is connected to the brush 12 through a transmission shaft. The transmission shaft extends out of the filter 11 and is connected to the brush 12. The brush 12 is in contact with the mesh surface of the filter 11.

[0020] Working principle:

[0021] After dust is generated, it accumulates in the gaps between the cutting plates. After the suction fan is started, the dust is affected by the negative pressure and enters and exits the box for air volume distribution. The dust collection pipe is connected to the dust collection box. A filter is installed in the dust collection box to filter the dust-containing air. In order to reduce the maintenance frequency of the filter, a brush is installed on the air inlet side of the dust collection box. The brush rotates to clean the filter. The brush brushes the dust attached to the filter into blocks. The block dust falls to the bottom of the dust collection box due to gravity. The dust removal port at the bottom of the dust collection box is opened regularly.

[0022] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
