DETAILED DESCRIPTION

[0049] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following will be further detailed to the utility model with specific embodiment.

[0050] It should be noted that, unless otherwise defined, technical or scientific terms used in the present application should be understood as having the common meaning in the field of the present application to which they belong.

[0051] As shown in Figure 1 and Figure 3 A fiber combing machine blank guiding device, comprising a support 1 and a conveying assembly provided on the support 1 for conveying fiber filaments; an aggregation assembly provided on the support 1 for converging the conveyed fiber filaments into slivers; at least one twisting assembly for twisting the slivers, the twisting assembly comprising: two oppositely arranged twisting parts, the twisting part comprising a frame 8 and two rotating rollers 10 rotatably arranged in the frame 8, a twisting belt 11 being sleeved between the two rotating rollers 10, a twisting space for twisting the slivers being formed between the twisting belts 11 of the two twisting parts; a driving structure for driving the twisting belts 11 of the two twisting parts to move towards each other; an adjusting structure provided between the frames 8 for adjusting the vertical spacing of the two frames 8 in the same twisting assembly, thereby changing the vertical spacing of the adjacent twisting belts 11; a blanking assembly for blanking the twisted slivers;

[0052] The above technical solution can adjust the spacing of the twisting belt 11. During use, the vertical spacing of the two frames 8 in the same twisting assembly can be changed by operating the adjusting structure. When the vertical spacing between the frames 8 changes, the rotating rollers 10 connected with the frames 8 will move vertically synchronously, and then the twisting belt 11 sleeved with the rotating rollers 10 will move vertically, so that the vertical spacing of the two twisting belts 11 in the same twisting assembly changes. When the spacing increases, thicker slivers can be twisted. Conversely, when the spacing decreases, thinner slivers can be twisted. Therefore, the appropriate twisting space can be adjusted according to the processing needs.

[0053] As shown in Figure 2As shown in the embodiment, the conveying assembly comprises two first support plates 2 arranged opposite to the upper end of the support frame 1, a conveying roller 3 rotatably arranged between the two first support plates 2, a conveying space for conveying the fiber filaments being formed between the conveying roller 3 and the surface of the support frame 1, and a first motor 4 with an output shaft connected to the end of the conveying roller 3, the first motor 4 being connected to the first support plates 2.

[0054] As shown in the embodiment, the polymerizing assembly comprises a polymerizing box 24 with channels 25 arranged at both ends, the size of the channel 25 close to the conveying assembly being larger than that of the channel 25 away from the conveying assembly, so as to form a horn structure with a wide inlet and a narrow outlet. Figure 1

[0055] The above technical solution can conveniently polymerize the carded fiber filaments into a sliver and send the sliver into the twisting assembly. In use, the fiber filaments pass below the conveying roller 3, and the conveying roller 3 presses the fiber filaments, so as to facilitate the movement of the fiber filaments by the friction between the conveying roller 3 and the fiber filaments when the conveying roller 3 rotates. When the first motor 4 operates, the conveying roller 3 rotates, and the fiber filaments move. The fiber filaments enter the polymerizing box 24 through the channel 25, are polymerized into a sliver, and then enter the twisting assembly.

[0056] As shown in the embodiment, the driving structure comprises a second motor 9 connected to the frame 8 of one of the twisting parts, an output shaft of the second motor 9 being connected to one of the rotating rollers 10 of the frame 8, a pulley 22 arranged at the end of the rotating roller 10 of each of the twisting parts, and a belt 23 sleeved on the two pulleys 22. Figure 3

[0057] The above technical solution can twist the sliver. In use, the second motor 9 is started to drive the rotating roller 10 in one of the frames 8 to rotate, so as to drive the twisting belt 11 connected to the rotating roller 10 to rotate. Since the rotating rollers 10 in the adjacent two frames 8 are drivingly connected through the pulley 22 and the belt 23, the two twisting belts 11 can be synchronously driven to rotate towards each other, so as to rub the sliver. The fiber raw material is twisted to be wound into a sliver, the bulkiness of the sliver is reduced, the sliver does not occupy a large space, the broken fiber filaments are also wound on the surface of the sliver, and the mutual adhesion between the slivers is reduced, so as to prevent the slivers from being pulled when the slivers are taken out, and the fiber filaments are broken.

[0058] As shown in the embodiment, the driving structure comprises a second motor 9 connected to the frame 8 of one of the twisting parts, an output shaft of the second motor 9 being connected to one of the rotating rollers 10 of the frame 8, a pulley 22 arranged at the end of the rotating roller 10 of each of the twisting parts, and a belt 23 sleeved on the two pulleys 22. Figure 3 ​​As shown, in this embodiment, the adjustment structure includes: an electric actuator 13 connected to one of the frames 8, the output end of the electric actuator 13 connected to another frame 8; a guide post 15 connected to one of the frames 8; a guide block 16 with a guide groove adapted to the guide post 15, the guide block 16 connected to another frame 8, thereby linearly guiding the movement of the two twisting parts through the guide post 15 and the guide block 16; the belt 23 is also provided with a tensioning structure; and the surface of the frame 8 is provided with a plurality of first fixing plates 12 and second fixing plates 14, wherein the first fixing plates 12 are used to connect the electric actuator 13, and the second fixing plates 14 are used to connect the guide post 15.

[0059] The above technical solution allows for adjustment of the spacing of the twisting belt 11. In use, the electric actuator 13 is activated. When the electric actuator 13 extends, the distance between the two frames 8 connected to it increases, thus widening the distance between the two twisting belts 11, suitable for twisting thicker yarns. Conversely, when the electric actuator 13 retracts, the distance between the two frames 8 connected to it decreases, thus narrowing the distance between the two twisting belts 11, suitable for twisting thinner yarns. The tensioning structure of the belt 23 ensures that the tension of the belt 23 remains constant even when the spacing of the frames 8 changes, ensuring that the belt 23 can stably drive the roller 10 to rotate, thereby driving the twisting belt 11 to transmit power stably. The guide post 15 and guide block 16 assist the electric actuator 13 in driving the two frames 8 vertically, preventing the frames 8 from tilting.

[0060] like Figure 3 and Figure 4 As shown, in this embodiment, the twisting assembly further includes: a guide frame 17 with a positioning groove 18 on its inner side, the guide frames 17 being arranged in pairs, and the positioning grooves 18 of adjacent guide frames 17 forming an installation space; a U-shaped strip 21 disposed in the positioning groove 18, the U-shaped strip 21 being used to guide the twisted sliver into the feeding assembly; a limiting frame 19 being provided at the upper end of the U-shaped strip 21, the limiting frame 19 having a through groove 20, the through groove 20 being interference-fitted with the U-shaped strip 21, and the outlet size of the U-shaped strip 21 being adjustable by moving the limiting frame 19;

[0061] The above technical solution can guide the twisted sliver into the next twisting component or directly into the feeding component. By setting the guide frame 17 and opening the positioning groove 18 inside the guide frame 17, the U-shaped strip 21 can be easily placed into the positioning groove 18 and fixed. By setting the limiting frame 19, it can slide and cooperate with the U-shaped strip 21. Thus, the exit size of the U-shaped strip 21 can be adjusted by the movable limiting frame 19 to adapt to guiding slivers of different thicknesses. When the sliver is thicker, the height of the limiting frame 19 needs to be increased to increase the exit size. Conversely, when the sliver is smaller, the height of the limiting frame 19 can be lowered to decrease the exit size.

[0062] As shown in Figure 1 and Figure 2 In this embodiment, the feeding assembly comprises: a second support plate 28 arranged at the bottom end of the support 1; a lead screw 30 rotationally connected with the second support plate 28; a third motor 29 connected with the second support plate 28 and used for driving the lead screw 30 to rotate forward and backward; a sliding block 31 provided with a lead screw groove; a sleeve 32 connected with the sliding block 31; a storage barrel 35 located at the lower end of the sleeve 32; a rotating disc 34 used for supporting the storage barrel 35; a fourth motor 33 connected with the support 1 and used for driving the rotating disc 34 to rotate; an inner groove 5 arranged on the surface of the support 1; and a guide roller 27 rotationally arranged in the inner groove 5, which is used for guiding the twisted sliver into the sleeve 32.

[0063] The above technical scheme can send the twisted sliver into the feeding assembly through the twisting assembly, and then wind the sliver in the sleeve 32 through the feeding assembly. One end of the twisted sliver sequentially passes through the U-shaped strip 21, the guide roller 27 and the sleeve 32 into the storage barrel 35. The third motor 29 drives the lead screw 30 to rotate forward and backward, thereby driving the sliding block 31 and the sleeve 32 to reciprocate. Meanwhile, the fourth motor 33 drives the rotating disc 34 to rotate, and the rotating disc 34 drives the storage barrel 35 to rotate, so that the sliver is uniformly wound in the storage barrel 35.

[0064] As shown in Figure 1 and Figure 3 In this embodiment, two twisting assemblies are arranged, which are a first twisting assembly 6 and a second twisting assembly 7. The first twisting assembly 6 and the second twisting assembly 7 have basically the same structure, and the difference lies in that the first twisting assembly 6 has two U-shaped strips 21, the second twisting assembly 7 has only one U-shaped strip 21, and two guide rods 26 are arranged between the first twisting assembly 6 and the second twisting assembly 7, and a guide gap for sending the sliver from the first twisting assembly 6 into the second twisting assembly 7 is formed between the guide rods 26.

[0065] The above technical scheme can further improve the twisting effect of the sliver. By arranging two twisting assemblies, the sliver can be twisted multiple times, so as to minimize the bulkiness of the sliver, so as to prevent the sliver from occupying a large storage space, and to enable the storage barrel 35 to store more sliver as much as possible. When the two U-shaped strips 21 of the first twisting assembly 6 are transmitted to the single U-shaped strip 21 of the second twisting assembly 7, the sliver will form a triangular structure, and the side of the sliver may rub against the equipment. By arranging the guide rods 26, the sliver can enter the second twisting assembly 7 in a straight line, so as to prevent the sliver from rubbing against the second twisting assembly 7 when it is inclined to enter the second twisting assembly 7.

[0066] Working principle: in use, start the electric push rod 13, when the electric push rod 13 stretches, the two frames 8 connected with the electric push rod 13 will increase the distance, so that the distance of the two twisting belts 11 is larger, which is suitable for twisting thicker slivers, on the contrary, when the electric push rod 13 retracts, the two frames 8 connected with the electric push rod 13 will reduce the distance, so that the distance of the two twisting belts 11 is smaller, which is suitable for twisting thinner slivers, the tensioning structure of the belt 23 can ensure that the tension of the belt 23 is still sufficient to maintain constant when the distance of the frame 8 changes, so that the belt 23 can stably drive the rotating roller 10 to rotate, and then drive the twisting belt 11 to stably transmit, the guide column 15 and the guide block 16 can assist the electric push rod 13 to drive the two frames 8 to move vertically, preventing the frame 8 from tilting;

[0067] By setting the guide frame 17 and opening the positioning groove 18 in the guide frame 17, the U-shaped strip 21 can be conveniently fixed in the positioning groove 18, and by setting the limiting frame 19, the limiting frame 19 can be slidably connected with the U-shaped strip 21, so that the outlet size of the U-shaped strip 21 can be adjusted by moving the limiting frame 19, when the sliver is thicker, the height of the limiting frame 19 needs to be increased to increase the outlet size, on the contrary, when the sliver is thinner, the height of the limiting frame 19 can be lowered to reduce the outlet size, so as to adapt to the guiding of slivers with different thicknesses.

[0068] The sliver twisted by the twisting assembly is sent into the sleeve 32, and then enters the storage barrel 35 through the sleeve 32, and the screw rod 30 is driven to rotate in reverse by the operation of the third motor 29, so as to drive the sliding block 31 and the sleeve 32 to reciprocate, at the same time, the fourth motor 33 drives the rotating disc 34 to rotate, the rotating disc 34 drives the storage barrel 35 to rotate, and then the sliver is uniformly wound in the storage barrel 35.
