Description

Technical Field

[0001] The invention relates to the technical field of Siro spinning machines, and in particular to an automatic adjustment device for a bell mouth of a double-inlet and single-outlet Siro spinning machine. Background Art

[0002] Siro spinning is a process of feeding two coarse yarns at a certain distance into a spinning frame. After drafting, the two single yarn strands are output by the front roller. Due to the transfer of twist, the single yarn strands have a small amount of twist. After splicing, they are further twisted into yarns similar to plied yarns. At present, the bell mouth used in Siro spinning machines is a double-inlet and single-outlet bell mouth, and the coarse yarn strands enter the drafting area through the two parts of the bell mouth.

DETAILED DESCRIPTION

[0034] 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.

[0035] Reference Figure 1 - Figure 8 , an automatic adjustment device for the bell mouth of a double-inlet and single-outlet Siro spinning machine, comprising an annular frame 1 and four bell mouth bodies 2.

[0036] A supporting mechanism for supporting the four bell-mouth bodies 2 is provided on the annular frame 1, and the supporting mechanism includes four slide grooves 3 opened at the upper end of the annular frame 1, and the four slide grooves 3 correspond to the four bell-mouth bodies 2 one by one. Two slide rods 4 are slidably connected to the inner walls of the slide grooves 3, and the side walls of the two slide rods 4 are fixedly connected to the corresponding side walls of the bell-mouth bodies 2.

[0037] The adjustment mechanism includes two first plates 5 fixedly connected to the upper end of the annular frame 1, the upper ends of the two first plates 5 are fixedly connected to the second plate 6, the lower end of the second plate 6 is fixedly connected to the fixing plate 7, and the upper end of the fixing plate 7 is provided with a placement groove 36 (such as Figure 4 As shown in the figure, the inner wall of the placement groove 36 is provided with four through grooves 8 corresponding to the four bell-mouth bodies 2, the inner walls of the four through grooves 8 are slidably connected with the first sliders 10, the lower end of the first slider 10 is elastically connected to the bottom of the through groove 8 through a plurality of first springs 9, the side walls of the four bell-mouth bodies 2 are fixedly connected with the second sliders 11, the four first sliders 10 correspond to the four second sliders 11 one by one, and the side walls of the first slider 10 are rotatably connected with the side walls of the corresponding second sliders 11 through the adjusting rod 12.

[0038] The moving rod 13 is located in the placement groove 36. The moving rod 13 is provided with an upward movement mechanism for driving the four first sliders 10 to move upward. The upward movement mechanism includes four grooves 14 opened on the side wall of the moving rod 13. The four grooves 14 correspond one-to-one to the four first sliders 10. The inner walls of the four grooves 14 are all slidably connected with baffles 15. The side walls of the baffles 15 are elastically connected to the inner walls of the grooves 14 through multiple magnetic springs 16.

[0039] The side wall of the second plate 6 is rotatably connected to a threaded cylinder 21 (such as Figure 6 As shown), the inner wall of the threaded cylinder 21 is threadedly connected with a rifle rod 22, the lower end of the rifle rod 22 is fixedly connected to the upper end of the moving rod 13, the upper end of the second plate 6 is fixedly connected to an electric push rod 23 through a bracket, and the movable end of the electric push rod 23 is fixedly connected to the upper end of the rifle rod 22.

[0040] In the initial state, the four baffles 15 are all located below the four first sliders 10. When the distance between the four bell-mouth bodies 2 needs to be adjusted, the electric push rod 23 is adjusted to retract. At this time, the electric push rod 23 drives the moving rod 13 to move up through the rifle rod 22, and drives the four baffles 15 to move up. At this time, the four baffles 15 drive the four first sliders 10 to move up, and then the four first sliders 10 will drive the four bell-mouth bodies 2 to move away from each other through the four adjusting rods 12 and the four second sliders 11, and automatically adjust the distance between the four bell-mouth bodies 2, so as to avoid the bell mouths on the siro spinning machine in the prior art being fixed, which makes it inconvenient to adjust the distance between the bell mouths according to the quality of the roving strips 25 during use, resulting in the roving strips 25 being prone to divergence, drifting and instability when passing through the bell mouth to the external special-shaped tube gathering groove, affecting the quality of the yarn after forming.

[0041] It should be noted that the outer diameter of the movable shaft of the electric push rod 23 is much smaller than the inner diameter of the threaded barrel 21 , so that the side wall of the movable shaft of the electric push rod 23 can move freely up and down on the inner wall of the threaded barrel 21 .

[0042] The inner side wall of the chute 3 is provided with a notch 17, and the side wall of the bell mouth body 2 facing the chute 3 is fixedly connected with a threaded rod 18, and the side wall of the threaded rod 18 passes through the notch 17 (such as Figure 2 As shown in the figure, the threaded rod 18 is located on the side wall outside the annular frame 1 and is threadedly connected with a nut 19, and the nut 19 is tightly fitted with the side wall of the annular frame 1 during the rotation process.

[0043] When the four bell-mouth bodies 2 are moving away from each other, the four bell-mouth bodies 2 respectively drive the four threaded rods 18 to move away from each other. At this time, the multiple first springs 9 are in an extended state, and the multiple first springs 9 have a tendency to contract. At this time, the four threaded rods 18 have a tendency to approach each other. At this time, after the positions of the four bell-mouth bodies 2 are adjusted, the four nuts 19 on the four threaded rods 18 are rotated so that the side walls of the four nuts 19 are tightly fitted with the side walls of the annular frame 1, thereby limiting the positions of the four threaded rods 18 to prevent the four bell-mouth bodies 2 from moving during subsequent use.

[0044] The side wall of the annular frame 1 is embedded with four pressure sensors 20 corresponding to the four baffles 15 one by one, and the four pressure sensors 20 correspond to the four nuts 19 one by one (such as Figure 2 As shown), the pressure sensor 20 is electrically connected to a plurality of magnetic springs 16 at its corresponding baffle 15 through an external control mechanism.

[0045] It should be noted that after the magnetic spring 16 is energized, due to electromagnetic induction, the magnetic spring 16 interacts with the current in the external magnetic field to generate pulling forces of different magnitudes to control the tensile deformation and movement state of the magnetic spring 16 .

[0046] After the side walls of the nut 19 are tightly fitted with the side walls of the annular frame 1, a pressure signal is sensed on the pressure sensor 20, and then the external control mechanism energizes the multiple magnetic springs 16 at the baffle 15 corresponding to the pressure sensor 20, and then the multiple magnetic springs 16 there are contracted, driving the baffle 15 there to move completely into the groove 14. At this time, the up and down movement of the moving rod 13 makes it possible for the baffle 15 completely located in the groove 14 to not drive the first slider 10 corresponding to the baffle 15 to move, and then the position of the bell-mouth body 2 can be adjusted as needed for targeted adjustment, that is, before adjustment, the nut 19 at the bell-mouth body 2 that does not require position adjustment can be tightly fitted with the side wall of the annular frame 1, thereby increasing the scope of use of the device.

[0047] It should be noted that the external control mechanism is mainly controlled by the PLC mainboard, and its control method is the existing technology and will not be described in detail here.

[0048] The side wall of the second plate 6 is sealed and rotatably connected to four guide cylinders 24 (such as Figure 6As shown in FIG. 1 ), the four guide cylinders 24 correspond to the four bell mouth bodies 2 one by one, and the side walls of the four bell mouth bodies 2 are all equipped with guide wheels 26 (as shown in FIG. 1 ) through brackets. Figure 1 As shown in the figure, a roving strip 25 is arranged in the guide cylinder 24, and the side wall of the roving strip 25 is in contact with the side wall of the guide wheel 26, so that the roving strip 25 can pass smoothly through the bell mouth body 2.

[0049] The inner wall of the guide cylinder 24 is fixedly connected with a sponge ring 37 (such as Figure 6 As shown, the inner side wall of the sponge ring 37 is in contact with the side wall of the roving strip 25, the side wall of the second plate 6 is provided with an annular cavity 29, and the side wall of the guide cylinder 24 located in the annular cavity 29 is provided with a plurality of liquid inlet holes 30 (as shown in FIG. Figure 6 and Figure 7 as shown).

[0050] The bottom of the placement groove 36 is fixedly connected to a pump frame 31, and the inner wall of the pump frame 31 is sealed and slidably connected to a pump plate 32. The upper end of the pump plate 32 is fixedly connected to the lower end of the moving rod 13 through a vertical rod 33. The lower part of the inner wall of the pump frame 31 is fixedly connected to a one-way suction pipe 34 (such as Figure 7 As shown in FIG. 1 ), the bottom of the pump liquid frame 31 is connected to the inner wall of the annular cavity 29 through a one-way liquid outlet pipe 35.

[0051] It should be noted that the one-way liquid suction pipe 34 only allows external disinfectant to enter the pump liquid frame 31, and the one-way liquid outlet pipe 35 only allows disinfectant to enter the annular cavity 29 from the pump liquid frame 31. After the position of the four bell-mouth bodies 2 is adjusted, the four nuts 19 are tightly fitted with the side walls of the annular frame 1. At this time, the four baffles 15 will all move completely into the four grooves 14. Then, the electric push rod 23 is adjusted to continuously extend and retract, driving the moving rod 13 to continuously move up and down. At this time, the moving rod 13 drives the pump liquid plate 32 to continuously move up and down through the vertical rod 33, so that the pump liquid frame 31 can continuously pump external disinfectant into the annular cavity 29 through the one-way liquid suction pipe 34 and the one-way liquid outlet pipe 35, and then the disinfectant can enter the sponge ring 37 through multiple liquid inlet holes 30, so that the disinfectant can be applied to the roving strip 25 during the transportation process, and the roving strip 25 can be sterilized, thereby avoiding the roving strip 25 in the prior art from having more bacteria and odor during the random placement process, resulting in the need for disinfection of the formed yarn.

[0052] The side wall of the threaded cylinder 21 located above the second plate 6 is fixedly connected to a first gear 27, and the side walls of the four guide cylinders 24 located above the second plate 6 are fixedly connected to second gears 28, and the side wall of the first gear 27 is meshed with the side walls of the four second gears 28 (such as Figure 6 as shown).

[0053] As the electric push rod 23 continuously extends and retracts to drive the rifle rod 22 to move up and down, the rifle rod 22 will drive the first gear 27 to rotate through the threaded cylinder 21, and then the first gear 27 will drive the four guide cylinders 24 to rotate through the four second gears 28, so that the sponge ring 37 can evenly apply disinfectant on the coarse yarn strip 25.

[0054] When the device needs to adjust the spacing between the four bell mouth bodies 2 during use, the four nuts 19 are first rotated to separate from the side walls of the annular frame 1, and the multiple magnetic springs 16 located in the four grooves 14 are all powered off and extended, driving the four baffles 15 to move out of the four grooves 14, and at this time, the four baffles 15 are all located directly below the four first sliders 10;

[0055] Then, the electric push rod 23 is adjusted to retract, and at this time, the electric push rod 23 drives the moving rod 13 to move up through the rifle rod 22, and drives the four baffles 15 to move up. At this time, the four baffles 15 drive the four first sliders 10 to move up, and then the four first sliders 10 will drive the four bell mouth bodies 2 to move away from each other through the four adjustment rods 12 and the four second sliders 11, and automatically adjust the distance between the four bell mouth bodies 2, so as to avoid that the bell mouths on the siro spinning machine in the prior art are all fixedly set, and it is inconvenient to adjust the distance between the bell mouths according to the quality of the roving strip 25 during use, resulting in the roving strip 25 being prone to divergence, drifting and instability when passing through the bell mouth to the external special-shaped tube gathering groove, affecting the quality of the yarn after forming;

[0056] Since after the distance between the four bell mouth bodies 2 is adjusted, the multiple first springs 9 are in an extended state, and thus the multiple first springs 9 have a tendency to contract, and the four threaded rods 18 have a tendency to approach each other, and then after the positions of the four bell mouth bodies 2 are adjusted, the four nuts 19 located on the four threaded rods 18 are rotated so that the side walls of the four nuts 19 are tightly fitted with the side walls of the annular frame 1, and then the positions of the four threaded rods 18 are limited, so as to prevent the four bell mouth bodies 2 from moving in position during subsequent use;

[0057] After the side walls of the nut 19 are tightly fitted with the side walls of the annular frame 1, the pressure sensor 20 senses a pressure signal, and then the external control mechanism energizes the multiple magnetic springs 16 at the baffle 15 corresponding to the pressure sensor 20, and then the multiple magnetic springs 16 at the baffle 15 contract, driving the baffle 15 at the location to move completely into the groove 14. At this time, the up and down movement of the moving rod 13 makes the baffle 15 completely located in the groove 14 not drive the first slider 10 corresponding to the baffle 15 to move;

[0058] Then, the roving strip 25 passes through the guide cylinder 24 and is output from the bell mouth body 2 through the guide wheel 26. Then, the electric push rod 23 is adjusted to continuously extend and retract, driving the moving rod 13 to continuously move up and down. At this time, the moving rod 13 drives the pump plate 32 to continuously move up and down through the vertical rod 33, so that the pump frame 31 can continuously pump the external disinfectant into the annular cavity 29 through the one-way suction pipe 34 and the one-way liquid outlet pipe 35. Then, the disinfectant can enter the sponge ring 37 through the multiple liquid inlet holes 30, so that the disinfectant can be applied to the roving strip 25 during the transportation process, and the roving strip 25 can be sterilized, so as to avoid the roving strip 25 in the prior art. There are more bacteria and odors in the process of random placement, resulting in the need for disinfection of the formed yarn;

[0059] And when the electric push rod 23 continuously extends and retracts to drive the rifle rod 22 to move up and down, the rifle rod 22 will drive the first gear 27 to rotate through the threaded cylinder 21, and then the first gear 27 will drive the four guide cylinders 24 to rotate through the four second gears 28, so that the sponge ring 37 can evenly apply disinfectant on the coarse yarn strip 25.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
