Description
Technical Field
[0001] The utility model relates to a dust suction fan, in particular to an automatic cotton cleaning dust suction fan. Background Art
[0002] During the roving weaving process, a lot of cotton scraps and cotton threads will be generated in the air and on the textile equipment. If they are not cleaned up in time, it will affect the health of the workers and affect the spinning of the roving, which is prone to breakage. Therefore, the cotton threads and cotton scraps in the weaving process need to be cleaned up in time. The traditional treatment method is to install a spinning dust removal fan, and collect the cotton threads and cotton scraps through the fan suction method. The inhaled cotton threads will be concentrated and attached to the dust-proof net outside the motor, and then the concentrated cotton threads and cotton scraps will be cleaned up manually. This method of manually cleaning cotton scraps will cause the motor to heat up and cause damage to the motor if it is not cleaned in time. Secondly, improper manual cleaning will affect the suction effect, resulting in a decrease in the subsequent cotton suction effect. Utility Model Content

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, an automatic cotton-cleaning dust-absorbing fan comprises a main body 1, wherein the main body 1 has a cavity, and the main body 1 is provided with an air outlet 2 and an air suction port 3, and cotton scraps and cotton threads enter the cavity from the air suction port 3, and the cavity is provided with a dust-absorbing fan 4 and a dust-proof net group 5, and the dust-proof net group 5 is located between the dust-absorbing fan 4 and the air suction port 3, and the dust-proof net group 5 is connected to an automatic cotton-cleaning component 6. The air suction port 3 is connected to a dust-absorbing duct, and the dust-absorbing duct runs through the workshop. After the dust-absorbing fan 4 is started, the dust-absorbing fan 4 will suck the cotton scraps and cotton threads in the workshop through the air suction port 3 to the dust-proof net group 5, and set a cotton-cleaning time for the automatic cotton-cleaning component 6, and clean the cotton scraps and cotton threads on the dust-proof net group 5 at a fixed time and point, so as to prevent the cotton scraps and cotton threads from accumulating too much on the dust-proof net group 5, causing the motor to heat up, and also affecting the suction effect and dust-cleaning efficiency.
[0024] The dust suction fan 4 is fixed in the cavity by a first fixing plate 11, and the dust screen set 5 is fixed in the cavity by a second fixing plate 12, and the second fixing plate 12 is located between the first fixing plate 11 and the air suction port 3. Figures 6 to 8 As shown, the dust-proof net group 5 includes a coarse roving dust-proof net 13 and a fine roving dust-proof net 14, which are respectively mounted on both sides of the second fixing plate 12, the coarse roving dust-proof net 13 is located near the dust suction fan 4, and the fine roving dust-proof net 14 is located near the air suction port 3. After the dust suction fan 4 is turned on, a negative pressure is generated at the air suction port 3, so that cotton scraps and cotton threads enter the cavity through the air suction port 3, and are temporarily attached to the fine roving dust-proof net 14 under the action of suction.
[0025] like Figure 5 As shown, the automatic cotton cleaning component 6 includes a motor 21 and a cotton cleaning rod 22. The motor 21 is fixed on the second fixed plate 12, and the motor 21 is located on the same side as the coarse yarn dust-proof net 13; the cotton cleaning rod 22 is connected to the motor 21 through a connecting shaft, and the cotton cleaning rod 22 is on the same side as the fine yarn dust-proof net 14. After a period of time, as more and more cotton scraps and cotton threads adhere to the fine yarn dust-proof net 14, it will affect the heat dissipation of the driving components and reduce the service life of the driving components. Start the motor 21 at a fixed time, and the motor 21 will drive the cotton cleaning rod 22 through the connecting shaft to clean the cotton scraps and cotton threads on the fine yarn dust-proof net 14. The cleaned cotton scraps and cotton threads will drop to the bottom of the main body 1 under the condition of negative pressure and self-weight above the cavity. The cotton scraps and cotton threads will not affect the heat dissipation of the driving components, nor will they affect the dust collection efficiency.
[0026] like Figure 2As shown, the cavity is provided with a backflow prevention cover 23, which is located between the fine yarn dustproof net 14 and the air suction port 3; the backflow prevention cover 23 is installed obliquely in the cavity, and the upper part of the backflow prevention cover 23 is the yarn feeding area 24, and the lower part is the yarn storage area 25. The backflow prevention cover 23 can only allow cotton scraps and cotton threads to pass through in one direction. After the cotton scraps and cotton threads cleaned by the cotton cleaning rod 22 enter the yarn storage area 25, they will not re-enter the yarn feeding area 24 due to the action of the dust suction fan 4. The backflow prevention cover 23 is installed obliquely, so that the cleaned cotton scraps and cotton threads will not stay on the backflow prevention cover 23, and no additional support will be provided for the cotton scraps and cotton threads, so that the cotton scraps and cotton threads can fall into the yarn storage area 25 more quickly, thereby improving the cleaning efficiency.
[0027] like Figure 5 As shown, the yarn storage area 25 is connected to the yarn suction fan 27 through the pipeline 26, and the yarn suction fan 27 transports the waste yarn stored in the yarn storage area 25. The air outlet 2 is located below the dust suction fan 4, and the area of the air outlet 2 is twice that of the air suction port 3. The area ratio of the air outlet 2 to the air inlet is 2:1, which will make the dust suction effect of the dust suction fan 4 optimal. The main body 1 is provided with a plurality of fixing holes for fixing, and the fixing holes fix the main body 1 to prevent the main body 1 from shifting during the dust suction process.
[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
