[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-7 As shown: Embodiment 1 of the present invention is:

[0031] A compact spinning drafting device with static elimination function for a spinning frame comprises a frame 1, on which three groups of drafting rollers 2 and static elimination rollers 3 are arranged in sequence, and a driving mechanism 4 connected to the three groups of drafting rollers 2 and static elimination rollers 3 is installed on one side wall of the frame 1;

[0032] The static elimination roller 3 includes a rotating shaft 31 and a double-headed screw 32 rotatably connected to the opposite side walls of the frame 1, and the thread grooves on both sides of the double-headed screw 32 are both bidirectional thread grooves. One end of the rotating shaft 31 passes through the side wall of the frame 1 and is connected to the driving mechanism 4. The outer wall of the rotating shaft 31 is fixedly connected to a lower roller 33. An internally hollow fixed shaft 34 is installed between the opposite side walls of the frame 1, and the fixed shaft 34 is rotatably sleeved on the outer wall of the double-headed screw 32 and is located above the lower roller 33. A plurality of water outlet holes are opened at the bottom of the fixed shaft 34 along the length direction, and a sponge sleeve 35 is sleeved on the outer wall of the fixed shaft 34. An end of the rotating shaft 31 passing through the frame 1 is fixedly connected to an incomplete gear column 36. The double-headed screw One end of 32 passes through the side wall of the frame 1 and is fixedly connected to a first driven gear 37 meshing with the incomplete gear column 36. The outer walls of the opposite ends of the double-headed screw rod 32 are symmetrically threaded with cylindrical sliders 38. The bottoms of the two sliders 38 are hinged with connecting rods 39. The bottoms of the two connecting rods 39 are hinged with fixing strips 310, and the shape of the fixing strips 310 is adapted to the inner wall of the bottom of the fixed shaft 34. A plurality of plugs 311 corresponding to the water outlets are arranged at the bottom of the fixing strip 310. The material of the plugs 311 is rubber. The incomplete gear column 36 rotates three circles to drive the plugs 311 to extend above the water outlet, and the slider 38 slides to one end of the double-headed screw rod 32.

[0033] In this embodiment, in order to facilitate the addition of water into the fixed shaft, a plurality of water inlet holes 312 are provided on the outer wall of the double-ended screw rod 32, and one end of the double-ended screw rod 32 is connected to an external water inlet pipe through a rotating flange.

[0034] In this embodiment, in order to limit the lifting and lowering of the plug, a limit ring 5 is provided on a side wall of the frame 1 away from the driving mechanism 4, and a limit strip 51 is provided at an equal angle on the inner wall of the limit ring 5. One end of a slider 38 close to the limit ring 5 passes through the side wall of the frame 1 and is provided with a limit groove 381 that cooperates with the limit strip 51.

[0035] In this embodiment, the driving mechanism 4 includes a driving motor 41 and sprockets 42 respectively mounted on the rotating shaft 31 and the outer wall of the stretching roller 2, and the sprockets 42 are connected by chains 43. The driving motor 41 is connected to the outermost group of stretching rollers 2, and a clamping wheel 44 for clamping the chain 43 is provided on the side wall of the frame 1.

[0036] The specific working process of the above embodiment is as follows:

[0037] When the yarn is guided, the yarn is passed through the three groups of drafting rollers 2 in sequence and then passed between the sponge cover 35 and the lower roller 33. At this time, the plug 311 in the fixed shaft 34 is separated from the water outlet, so that the water in the fixed shaft 34 can flow out into the sponge cover 35 along the water outlet, so that the bottom of the sponge cover 35 is in a wet state, and then the driving motor 41 is started. The driving motor 41 drives the multiple groups of sprockets 42 to rotate synchronously through the chain 43, thereby driving the drafting rollers 2 and the lower roller 33 to rotate to guide the yarn. After passing under the sponge cover 35, the yarn contacts the bottom of the sponge cover 35, thereby humidifying the yarn, thereby eliminating static electricity on the surface of the yarn.

[0038] The incomplete gear column 36 is driven to rotate during the rotation of the lower roller 33, and the incomplete gear column 36 drives the first driven gear 37 and the double-headed screw 32 to rotate a certain angle, thereby driving the two sliders 38 to slide in a direction close to each other under the limiting action of the limiting ring 5, so that the plug 311 slides downward and is initially inserted into the water outlet hole to block the water outlet hole, and as the incomplete gear column 36 continues to rotate, it continues to drive the plug 311 to be inserted into the water outlet hole until the incomplete gear column 36 rotates three times and the plug 311 is It is fully inserted into the water outlet, and at this time the slider 38 slides to one end of the double-headed screw rod 32, and as the lower roller 33 continues to rotate, the two sliders 38 are driven to slide in the direction away from each other, gradually pulling the plug 311 from the water outlet until the incomplete gear column 36 rotates three times again, so that the plug 311 is separated from the water outlet again, so that the water in the fixed shaft 31 flows out into the sponge cover 35 again, and the sponge cover 35 is humidified again. This reciprocating process not only ensures the effect of yarn humidification and static removal, but also avoids the waste of water resources.

[0039] When water needs to be added to the fixed shaft 34 , water can be added to the double-headed screw 32 through an external water inlet pipe and flow out into the fixed shaft 34 through the water inlet hole 312 .

[0040] like Figure 1-7 As shown: Embodiment 2 of the present invention is:

[0041] The difference between this embodiment and the first embodiment is that:

[0042] In this embodiment, the fixed shaft 34 is rotatably connected to the two opposite side walls of the frame 1, and six groups of water outlet holes are arranged at equal angles on the outer wall of the fixed shaft 34. One end of the fixed shaft 34 passes through the side wall of the frame 1 and is fixedly connected to the groove wheel 313. The side wall of the frame 1 is rotatably connected to the rotating rod 314. The outer wall of the rotating rod 314 is fixedly connected to the second driven gear 315 which is meshed with the incomplete gear column 36. The incomplete gear column 36 first meshes with the first driven gear 37 and then with the second driven gear 315. The surface of the second driven gear 315 is respectively fixedly connected with a turntable 316 and a column 317 which cooperate with the groove wheel 313. When the column 317 contacts the groove wheel 313, it drives the groove wheel 313 and the fixed shaft 34 to rotate 60 degrees. Six baffles 341 are arranged on the inner wall of the fixed shaft 34. The six baffles 341 divide the fixed shaft 34 into six areas, and a group of water outlet holes is arranged in each of the six areas.

[0043] In this embodiment, in order to prevent the fixed shaft 34 from rotating with the yarn during the yarn drafting process, the fixed shaft 34 is rotatably connected to the opposite side walls of the frame 1 via a one-way bearing, that is, the fixed shaft 34 can only rotate in one direction, so that during the yarn drafting process, the fixed shaft 34 can remain stable, and when the column 317 drives the groove wheel 313 to rotate, it can synchronously drive the fixed shaft 34 to rotate to achieve position switching.

[0044] The specific working process of the above embodiment is as follows:

[0045] During the rotation of the lower roller 33, the incomplete gear column 36 first meshes with the first driven gear 37 to drive the double-headed screw 32 to rotate, and then meshes with the second driven gear 315 to drive the turntable 316 and the column 317 to rotate 60 degrees. When the incomplete gear column 36 rotates to the sixth circle, the plug 311 is separated from the water outlet again. The incomplete gear column 36 meshes with the second driven gear 315, thereby driving the turntable 316 and the column 317 to rotate 60 degrees again. At this time, the column 3 17 is inserted into the vertical groove of the groove wheel 313, so that as the rotation of the column 317 drives the groove wheel 313 and the fixed shaft 34 to rotate 60 degrees, the sponge cover part that is used more times is rotated to the next angle position and the sponge cover 35 at the next position is rotated to the bottom, and the water in the fixed shaft 34 flows out again into the sponge cover 35 at this position to humidify the sponge cover 35, and the sponge cover 35 rotated to the next angle position is cleaned in time to clean the rough yarn attached to the surface of the sponge cover 35.

[0046] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
