Detailed Embodiment

[0017] The present utility model will be further described in detail below in conjunction with the embodiments of the drawings.

[0018] Such as Figures 1-5As shown in the figure, a lightweight and energy-saving waste yarn suction device for a sock knitting machine in this embodiment includes a box body 1 and a fan 2. Inside the box body 1, there are two cotton bins arranged in parallel: a main cotton bin 15 and a secondary cotton bin 11. A partition 12 is provided between the two cotton bins, and the partition 12 is fixed inside the box body 1. The fan 2 is arranged inside the box body 1 and is connected to the cotton bins. An air inlet 5 and an air outlet 6 are provided at the top of the box body 1. The main cotton bin 15 and the secondary cotton bin 11 are alternately connected to the air inlet 5. The main cotton bin 15 is provided with a main cotton bin shunt inlet 21, and the secondary cotton bin 11 is provided with a secondary cotton bin shunt inlet 20, that is, the main cotton bin shunt inlet 21 and the secondary cotton bin shunt inlet 20 are alternately connected to the air inlet 5, and gravity valves are respectively provided thereon. A main cotton bin closing valve 19 is provided inside the main cotton bin 15, and a secondary cotton bin closing valve 18 is provided inside the secondary cotton bin 11. A rotating shaft 14 horizontally penetrates through the main cotton bin closing valve 19, the partition 12, and the secondary cotton bin closing valve 18. The main cotton bin closing valve 19 is fixed to the rotating shaft 14 through a main bearing 13 and a positioning bearing 17, and the secondary cotton bin closing valve 18 is fixed to the rotating shaft 14 through a secondary bearing 16 and a positioning bearing 17. A main blade 23 is provided inside the main cotton bin closing valve 19, and a secondary blade 22 is provided inside the secondary cotton bin closing valve 18. The main blade 23 and the secondary blade 22 are arranged on the rotating shaft 14, and the main blade 23 and the secondary blade 22 are arranged in a cross shape. A main shunt closing port is opened on the main cotton bin closing valve 19, and a secondary shunt closing port is opened on the secondary cotton bin closing valve 18. When the rotating shaft rotates, the main blade 23 closes the main shunt closing port, making the main shunt closing port fully closed. At this time, the secondary shunt closing port is just in a fully open state, that is, the air inlet 5 is connected to the secondary cotton bin 11. Conversely, the secondary blade 22 closes the secondary shunt closing port, making the secondary shunt closing port fully closed. At this time, the main shunt closing port is just in a fully open state, that is, the air inlet 5 is connected to the main cotton bin 15. A mixing chamber 4 is provided between the cotton bin and the fan 2. Under the action of the fan 2, air enters a cotton bin from the air inlet. The air filtered by the cotton bin enters the fan 2 through the mixing chamber 4 and then flows out through the air outlet 6. A vertically installed filter screen 3 is provided at the air outlet end of the cotton bin to intercept waste filaments in the air inside the cotton bin. The air inside the cotton bin flows into the mixing chamber from the air outlet end after being filtered by the filter screen 3 and then flows out through the air outlet 6. A main bin door 10 for opening the main cotton bin 15 is provided on the box body 1. A main pressure relief valve 9 is provided on the box body 1, and the main pressure relief valve 9 corresponds to the main bin door 10. Opening the main pressure relief valve 9 balances the air pressure inside and outside the main cotton bin 15, thereby facilitating the opening of the main bin door 10. A secondary bin door 8 for opening the secondary cotton bin 11 is provided on the box body 1. A secondary pressure relief valve 7 is provided on the box body 1, and the secondary pressure relief valve corresponds to the secondary cotton bin. Opening the secondary pressure relief valve balances the air pressure inside and outside the secondary cotton bin, thereby facilitating the opening of the secondary bin door and allowing operators to regularly clean and collect the bin.

[0019] The main cotton bin shunt inlet 21 and the auxiliary cotton bin shunt inlet 20 are respectively provided with gravity valves, and the gravity valves tend to always close the main cotton bin shunt inlet 21 and the auxiliary cotton bin shunt inlet 20 under the action of gravity. Only when the current cotton bin is in operation, the gravity valve will open under the action of the negative pressure inside the cotton bin to allow air to enter the operating cotton bin from the air inlet.

[0020] Device working principle: The main cotton bin shunt inlet and the auxiliary cotton bin shunt inlet share one air inlet, and the structure is that one air inlet becomes two shunt inlets. Each of the main cotton bin shunt inlet and the auxiliary cotton bin shunt inlet has a gravity valve to close the main cotton bin shunt inlet and the auxiliary cotton bin shunt inlet. When the rotating shaft rotates, the main blade and the auxiliary blade rotate synchronously, so that the main blade closes the main cotton bin closing valve. At this time, the auxiliary cotton bin closing valve is just in the fully open working state, and the gravity valve of the auxiliary cotton bin shunt inlet is sucked open, and the auxiliary cotton bin works normally. At this time, the main pressure relief valve can be opened, and then the main bin door can be opened to quickly take out and dispose of the waste yarn. The auxiliary cotton bin can meet the performance requirements of the unit in the lowest working state during this process, and then the main bin door is closed. On the contrary, the auxiliary blade closes the auxiliary cotton bin closing valve. At this time, the main cotton bin closing valve is just in the fully open working state, and the gravity valve of the main cotton bin shunt inlet is sucked open, and the main cotton bin works normally. If the waste yarn accumulated in the auxiliary cotton bin reaches the treatment requirement, the auxiliary pressure relief valve can be opened, and then the auxiliary bin door can be opened to take out the waste yarn.

[0021] The structure of this application is compact, occupies a small space, and has flexible closing. As long as the rotating shaft is rotated, the opening and closing of the two cotton bins can be controlled, the working states of the two cotton bins can be quickly switched, the interval between yarn extraction is extended, and the cleaning operation of the cotton bin is facilitated.

[0022] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
