The space inside the lower dust hood 220 in the textile fabric winding dust collection device is larger, that is, the space between the upper dust hood 210 and the lower dust hood 220 is larger, so that the flow rate of negative pressure air is influenced, and the dust collection effect is not strong enough.
Referring to fig. 6 and 11, the textile fabric winding dust collection device further includes a dust collection auxiliary assembly 50, and the dust collection auxiliary assembly 50 includes a guide shell 510, a guide plate 520 and a standpipe 530, wherein the top of the guide shell is provided with an arc structure. The air guide shell 510 is located outside the second shaft 280 and the second swing block 290, and the end of the air guide shell 510 is fixed to the inner wall of the lower dust collecting cover 220. The two guide plates 520 are respectively and obliquely arranged at two sides of the top of the guide shell 510, and the guide plates 520 and the guide shell 510 can be integrally formed; the top end of the vertical pipe 530 is communicated with the bottom of the air guide shell 510 in a welding manner, and the bottom end of the vertical pipe 530 is communicated with the through hole 270 at the bottom of the lower dust hood 220, i.e. the vertical pipe 530 and the bottom wall inside the lower dust hood 220 can be fixedly installed in a welding manner.
When the cloth passing through the space between the upper dust collection cover 210 and the lower dust collection cover 220 is swung by the first swing block 260 and the second swing block 290 to clean dust, the dust enters the inside of the air guide shell 510 along with air along the air guide plates 520 at two sides of the air guide shell 510, and finally enters the inside of the dust collection box 310 through the through holes 270, the lower pipe 340 and the connecting pipe 350 by the vertical pipes 530 at the bottom of the air guide shell 510. The arrangement of the guide case 510 and the guide plate 520 inside the lower dust hood 220 reduces the space between the upper dust hood 210 and the lower dust hood 220, so that the flow rate of the internal air circulation is increased, and the dust between the upper dust hood 210 and the lower dust hood 220 can be better absorbed and cleaned.
When the cloth ironing part 40 is not disposed inside the upper dust hood 210, the dust collection auxiliary assemblies 50 may be disposed inside both the upper dust hood 210 and the lower dust hood 220, further reducing the space for air flow between the upper dust hood 210 and the lower dust hood 220, and further improving the internal air flow rate, i.e., further improving the dust collection cleaning ability.
