DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 3 As shown, an automatic dust removal device for a circular knitting machine provided by an embodiment of the utility model comprises a circular knitting machine body 1, a dust cover 2 is provided on the outer side of the body 1, a cavity 3 is provided in the middle of the dust cover 2, an air inlet 4 is provided on the top of the cavity 3, a plurality of feed hoppers 5 extending into the cavity 3 are provided on the inner wall of the dust cover 2, the feed hopper 5 is conical, a wind cover 6 is provided on the outer side of the feed hopper 5, and an exhaust fan 7 for improving air circulation is provided at the bottom of the cavity 3.

[0025] refer to Figure 3 A plurality of spiral guide grooves 8 are provided on the outer wall of the feed hopper 5 , and the air cover 6 is connected to the cavity 3 through the guide grooves 8 .

[0026] By adopting the above solution, the spiral guide groove 8 is provided, so that the flow rate of the gas can be further increased, a negative pressure can be formed at the end of the feed hopper 5, and dust can be removed when the air flow inside the dust cover 2 is small.

[0027] refer to Figure 2 A storage chamber 9 is provided at the bottom of the cavity 3 , and a first partition 10 , a second partition 11 and an air outlet 12 are sequentially provided inside the storage chamber 9 , and the exhaust fan 7 is located inside the air outlet 12 .

[0028] By adopting the above solution, the dust and debris generated during textile processing can be collected by providing the storage chamber 9, the first partition plate 10, the second partition plate 11 and the air outlet pipe 12.

[0029] refer to Figure 1 and Figure 2 The air inlet 4 is connected to an air duct 13 through a filter box 15 , one end of the air duct 13 is connected to the air outlet 12 , and the other end of the air duct 13 is connected to a plurality of wind shields 6 through the cavity 3 .

[0030] By adopting the above solution, the airflow can be redirected into the air hood 6 by providing the air guide duct 13, thereby improving the dust removal effect.

[0031] refer to Figure 2 The bottom of the storage chamber 9 is provided with an inspection door 14 for cleaning dust.

[0032] With the above solution, by providing the inspection door 14, dust and the like can be easily and promptly cleared out.

[0033] refer to Figure 2 A filter box 15 is disposed on the top of the air inlet 4 , and a plurality of filter screens 16 are disposed inside the filter box 15 .

[0034] By adopting the above solution, the gas entering the cavity 3 can be filtered by providing the filter box 15 and the filter net 16 .

[0035] When in use, the exhaust fan 7 is started. At this time, the gas near the air inlet 4 is filtered through the filter 16 and then enters the cavity 3. When the airflow passes through the feed hopper 5, the flow rate near the feed hopper 5 will increase, so that a local negative pressure is formed near the feed hopper 5 in the cavity 3, so that the dust and debris near the feed hopper 5 enter the cavity 3, and then the dust enters the storage cavity 9. After being blocked by the first partition 10 and the second partition 11, the gas enters the multiple wind hoods 6 from the air outlet 12 through the air duct 13, thereby increasing the flow rate near the feed hopper 5 and improving the dust removal effect.

[0036] To sum up: the automatic dust removal device of the large circular knitting machine can be used when the large circular knitting machine is working by arranging the main body 1, the dust removal cover 2, the cavity 3, the air inlet 4, the feed hopper 5, the wind cover 6, the exhaust fan 7, the guide groove 8, the storage chamber 9, the first partition 10, the second partition 11, the air outlet 12, the air guide duct 13, the inspection door 14, the filter box 15 and the filter net 16. The dust removal effect is good, which solves the problem that the dust removal of the existing large circular knitting machine during operation easily affects the normal conveying of the spinning thread and the dust removal effect is poor.
