Detailed Description

As shown in fig. 1, 3 and 4, an automatic cotton picking and dust collection fan comprises a main body 1, wherein a cavity is arranged in the main body 1, an air outlet 2 and an air suction inlet 3 are arranged on the main body 1, cotton scraps and cotton threads enter the cavity from the air suction inlet 3, a dust collection fan 4 and a dust collection net group 5 are arranged in the cavity, the dust collection net group 5 is positioned between the dust collection fan 4 and the air suction inlet 3, and an automatic cotton picking assembly 6 is connected to the dust collection net group 5. The dust absorption pipeline is connected to the inlet scoop 3, and the dust absorption pipeline runs through the workshop, and after dust absorption fan 4 starts, dust absorption fan 4 can inhale cotton bits and cotton thread in the workshop to on the dust screen group 5 through inlet scoop 3 to set for the time of picking up cotton for automatic cotton picking up subassembly 6, regularly fixed point clear up cotton bits and cotton thread on the dust screen group 5, prevent cotton bits and cotton thread to build up too much on the dust screen group 5, lead to the motor to generate heat, and still influence the effect of induced drafting and influence dust collection efficiency.

The dust suction fan 4 is fixed in the cavity through a first fixing plate 11, the dust screen group 5 is fixed in the cavity through a second fixing plate 12, and the second fixing plate 12 is positioned between the first fixing plate 11 and the air suction inlet 3. As shown in fig. 6 to 8, the dust-proof net set 5 includes a roving dust-proof net 13 and a spun yarn dust-proof net 14, the roving dust-proof net 13 and the spun yarn dust-proof net 14 are respectively mounted on two sides of the second fixing plate 12, the roving dust-proof net 13 is located on the side near the dust suction fan 4, and the spun yarn dust-proof net 14 is located on the side near the suction inlet 3. After the dust suction fan 4 is started, negative pressure is generated at the air suction port 3 to enable cotton scraps and cotton threads to enter the cavity through the air suction port 3, and the cotton scraps and cotton threads are temporarily attached to the spun yarn dustproof net 14 under the action of suction force.

As shown in fig. 5, the automatic cotton picking assembly 6 comprises a motor 21 and a cotton picking rod 22, the motor 21 is fixed on the second fixing plate 12, the motor 21 is located on the same side of the roving dust screen 13, the cotton picking rod 22 is connected with the motor 21 through a connecting shaft, and the cotton picking rod 22 is on the same side of the roving dust screen 14. After a period of time, as more cotton scraps and cotton threads are attached to the spun yarn dustproof net 14, heat dissipation of the driving component is affected, and the service life of the driving component is shortened. The motor 21 is started at regular time, the motor 21 drives the cotton picking rod 22 through the connecting shaft to clean cotton scraps and cotton threads on the spun yarn dustproof net 14, and the cleaned cotton scraps and cotton threads can descend to the bottom of the main body 1 under the condition that negative pressure and dead weight exist above the cavity. The cotton scraps and cotton threads can not influence the heat dissipation of the driving part and the dust collection efficiency.

As shown in fig. 2, a backflow prevention cover 23 is arranged in the cavity, the backflow prevention cover 23 is positioned between the spun yarn dustproof net 14 and the air suction inlet 3, the backflow prevention cover 23 is obliquely arranged in the cavity, a yarn feeding area 24 is arranged above the backflow prevention cover 23, and a yarn storage area 25 is arranged below the backflow prevention cover 23. The backflow preventing cover 23 can only run cotton scraps and cotton threads to pass through in one direction, and after the cotton scraps and cotton threads cleaned by the cotton cleaning rod 22 enter the yarn storage area 25, the cotton scraps and cotton threads can not reenter the yarn feeding area 24 under the action of the dust suction fan 4. The anti-reflux cover 23 is obliquely arranged, so that the cleaned cotton scraps and cotton threads cannot stay on the anti-reflux cover 23, additional supporting force cannot be provided for the cotton scraps and the cotton threads, the cotton scraps and the cotton threads can more quickly fall into the yarn storage area 25, and the cleaning efficiency is improved.

As shown in fig. 5, the yarn storage area 25 is connected to a yarn suction fan 27 through a pipe 26, and the yarn suction fan 27 conveys out the waste yarn stored in the yarn storage area 25. The air outlet 2 is positioned below the dust collection fan 4, the area of the air outlet 2 is twice that of the air suction inlet 3, and the dust collection effect of the dust collection fan 4 can be optimized when the area ratio of the air outlet 2 to the air inlet is 2:1. The main body 1 is provided with a plurality of fixing holes for fixing, and the main body 1 is fixed by the fixing holes to prevent the main body 1 from shifting in the dust collection process.
