Description

Technical Field

[0001] This invention relates to the field of spinning technology, and in particular to a fiber sliver winding device and its control method. Background Technology

[0002] In recent years, the traditional spinning industry has been undergoing profound changes. For carded yarn production systems, the spinning process includes opening and cleaning, carding, drawing, roving, spinning, and winding. Among these, the carding-opening integrated system, which connects opening and cleaning with carding, is widely used; the roving integrated system, which connects roving and spinning, is gradually being promoted; and the spinning-winding integrated system, which connects spinning and winding, is also being adopted by some companies. However, the connection between carding, drawing, and roving is not yet mature. For combed yarn production systems, the spinning process includes opening and cleaning, carding, combing preparation and combing, drawing, roving, spinning, and winding. Similarly, the connection between carding, combing, drawing, and roving is not yet mature.

[0003] Sliver is one of the most important semi-finished products in the spinning process, involving three major steps: carding, combing, and drawing. During production, the sliver needs to be wound in an orderly fashion within a sliver can of a certain diameter. In the traditional winding process, the winding mechanism, the winding disc, and the sliver can rotate in tandem. This coordinated rotation ensures the sliver is wound continuously within the can in a specific elliptical structure, with the slivers not completely overlapping. Therefore, the winding disc located at the top of the sliver can needs to be driven by both the sliver and the can itself. Furthermore, the current winding method results in an uneven density distribution of the sliver within the can, significantly limiting the can's winding capacity. Consequently, without the ability to intelligently connect and transport the sliver can, this increases the frequency of can changes and transport, increasing the labor intensity for workers and reducing production efficiency. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is how to achieve a more uniform distribution of fiber slivers within the sliver can, thereby increasing the capacity of the sliver can.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fiber sliver winding device, comprising: an output unit including an output disk, wherein the output disk is provided with a fiber sliver input port and a fiber sliver output port communicating therewith; a driving cylinder is provided at the fiber sliver input port, the driving cylinder is fixedly connected to the output disk and passes through the fiber sliver input port; the driving cylinder is driven by a first motor; and a pressing output pair is also provided at the fiber sliver output port for outputting fiber sliver; a winding transmission unit including a transverse fixed disk, a moving component provided at the bottom of the transverse fixed disk, a bearing component provided at the top of the transverse fixed disk, and a sliver cylinder provided at the top of the bearing component.

[0007] In a preferred embodiment of the fiber sliver winding device of the present invention, an input cylinder is further sleeved outside the driving cylinder, and the input cylinder is rotatably engaged with the output disc.

A first fixing sleeve is provided at both ends of the pressing output active roller, and a second fixing sleeve is provided at both ends of the pressing output passive roller. The first fixing sleeves are fixed to the side of the fiber sliver output port, and the first fixing sleeve and the second fixing sleeve are rotatably engaged with the pressing output active roller and the pressing output passive roller, respectively.

[0009] In a preferred embodiment of the fiber sliver winding device of the present invention, a first spring is further provided between the second fixed sleeve and the output disc, and magnets are also provided on both the first fixed sleeve and the second fixed sleeve.

[0010] In a preferred embodiment of the fiber sliver winding device of the present invention, an output connecting shaft is fixedly provided at the bottom of the output disc, and the connecting shaft is connected to the pressing output active roller through a bevel gear set.

[0011] In a preferred embodiment of the fiber sliver winding device of the present invention, the moving component includes a first pulley and a second pulley disposed at the bottom of the transverse fixed plate. The first pulley is rotatably engaged with the transverse fixed plate, and the second pulley is rotatably engaged with the transverse fixed plate via a transverse driving rod and is driven by a second motor. The moving component also includes a slide rail disposed at the bottom of the first pulley and the second pulley and cooperating with them.

[0012] In a preferred embodiment of the fiber sliver winding device of the present invention, the bearing component includes a transverse rotating disk disposed in the middle of the transverse fixed disk, the transverse rotating disk being rotatably coupled with the transverse fixed disk and the transverse rotating disk being driven by a third motor.

[0013] In a preferred embodiment of the fiber sliver winding device of the present invention, the bearing component further includes a sliver tube, which is placed on the transverse rotating disk, and its interior includes, from top to bottom, a sliver holding tray and a second spring.

[0014] Another object of the present invention is to provide a control method for a fiber sliver winding device, comprising: twisting and outputting the fiber sliver by means of the pressing output; simultaneously performing horizontal reciprocating motion and circumferential rotation motion on the sliver can by means of the transverse fixed disk and the transverse rotating disk; so that the fiber sliver forms an in-cut cotton sheet winding and a full cotton sheet winding on the sliver can.

[0015] In a preferred embodiment of the control method for the fiber sliver winding device of the present invention, the inner-cut cotton sheet is a circle composed of several fiber sliver windings and tangent to the inner side of the sliver tube, and the all-cotton sheet is a circle composed of several fiber sliver windings and overlapping with the inner side of the sliver tube.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a fiber sliver winding device, which includes an output unit 100 and a sliver winding transmission unit 200.

[0030] Specifically, the output unit 100 includes an output disk 101, which is a hollow and closed cylinder with a radius between 150 and 200 mm and a height between 10 and 20 mm. A fiber sliver input port 101a is located at the center of the top of the output disk 101, and a fiber sliver output port 101b is located at the bottom. The fiber sliver enters through the fiber sliver input port 101a and exits through the fiber sliver output port 101b. There is a certain distance between the axes of the fiber sliver output port 101b and the fiber sliver input port 101a, which is equal to the radius of the fiber sliver loop (500).

[0031] A drive cylinder 102 is also fixedly installed at the fiber strip inlet 101a. The drive cylinder 102 is a hollow cylinder with open ends. The axis of the drive cylinder 102 after connection coincides with the axis of the fiber strip inlet 101a.

[0032] The output disk 101 is fixedly connected to the platform. An input cylinder 106 is also provided on the platform. The input cylinder 106 is a hollow cylinder with open ends. The upper end of the input cylinder 106 is fixedly connected to the platform. The upper port of the input cylinder 106 after connection is interconnected with the converging horn mouth. The input cylinder 106 passes through the drive cylinder 102 and extends into the output disk 101 through the fiber strip input port 101a. The input cylinder 106 and the output disk 101 rotate and cooperate.

[0033] The drive cylinder 102 is connected to the first motor 103 via a belt, which in turn drives the output disc 101 to rotate.

[0034] The fiber output port 101b has a rectangular structure. A pressing output pair 104 is provided on the fiber output port 101b. The pressing output pair 104 includes a pressing output active roller 104a and a pressing output passive roller 104b. The pressing output active roller 104a includes a pressing output active roller shaft and a pressing output active roller sleeve. The pressing output active roller sleeve is fitted on the pressing output active roller shaft, and the two are integrally fixedly connected.

[0035] First fixing sleeves 104c are installed at both ends of the pressing output active roller shaft of the pressing output active roller 104a, and are rotatably engaged with the pressing output active roller shaft through bearings. The first fixing sleeves 104c are fixed on the output disk 101 at the fiber output port 101b, so that the connected pressing output active roller 104a can rotate freely. At the same time, magnets are also installed on the first fixing sleeves 104c.

[0036] The pressing output passive roller 104b includes a pressing output passive roller shaft and a pressing output passive roller sleeve. The pressing output passive roller sleeve is fitted onto the pressing output passive roller shaft, and the two are rotatably connected by a bearing, so that the connected pressing output passive roller sleeve can rotate freely.

[0037] A second fixed sleeve 104d is fixedly installed on both ends of the pressing output passive roller shaft extending from the pressing output passive roller sleeve. A magnet with fixed magnetism is respectively provided on one side of the outer surface of the second fixed sleeve 104d, and a first spring 105 is respectively provided on the other side of the outer surface of the second fixed sleeve 104d. The first spring 105 is fixedly connected to one side of the fiber output port 101b. A connecting shaft 107 is provided at the center of the lower circular surface of the output disk 101. The upper end of the connecting shaft 107 is fixedly connected to the lower circular surface of the output disk 101. One end of the pressing output active roller shaft extending from the pressing output active roller sleeve is connected to the connecting shaft 107 through a bevel gear set 108. After connection, the rotational linear speed of the pressing output active roller sleeve is equal to the output speed of the fiber strip.

[0038] The transverse moving fixed plate 204 has a cuboid structure with two pairs of pulleys at its bottom: a first pulley 201a and a second pulley 201b. The first pulley 201a is rotatably engaged with the transverse moving fixed plate 204 via a pivot, while the second pulleys 201b are fixedly mounted at both ends of the transverse moving drive rod 201c, which passes through the transverse moving fixed plate 204. The end of the transverse moving drive rod 201c is connected to the output end of the second motor 201d. When the second motor 201d rotates, it drives the transverse moving drive rod 201c to rotate, which in turn drives the second pulleys 201b to rotate. Furthermore, both the first pulley 201a and the second pulley 201b are placed on a slide rail 201e, allowing the transverse moving fixed plate 204 to move horizontally along the slide rail 201e when the second pulley 201b rotates.

[0039] The transverse rotating disk 202a is installed in the middle of the transverse fixed disk 204. It has a spherical cap structure with a convex center. The transverse rotating disk 202a and the transverse fixed disk 204 are connected by bearings, allowing the transverse rotating disk 202a to rotate freely after connection. A third motor 202b is also provided at the bottom of the transverse rotating disk 202a, which can drive the transverse rotating disk 202a to rotate.

[0040] A strip tube 203, which is a cylindrical shape with a certain internal space, is placed on a transverse rotating disk 202a. The bottom of the strip tube 203 has an upward-concave spherical segment groove that mates with an upward protrusion on the transverse rotating disk 202a. A strip-holding tray 203a is also provided inside the strip tube 203, and a second spring 203b is provided at the bottom of the tray 203a. The bottom of the second spring 203b is fixedly connected to the bottom of the strip tube 203. The tray 203a is freely placed on the second spring 203b, and after placement, the tray 203a is flush with the upper end of the strip tube 203 and can move along the height direction of the second spring 203b. The diameter of the second spring 203b decreases first and then increases from top to bottom, and the diameter of the lower end of the second spring 203b is smaller than the diameter of its upper end.

[0041] In use, the sliver can 203 is first placed on the transverse rotating disk 202a. During this process, external force is used to place the sliver can 203 directly on the transverse rotating disk 202a. Due to the convex structure of the transverse rotating disk 202a, the placed sliver can 203 naturally moves to the center of the transverse rotating disk 202a under its own gravity. The fiber sliver output by the output unit 100 passes through the gathering trumpet mouth to obtain the fiber sliver of the required linear density. The obtained fiber sliver enters the output disk 101 through the fiber sliver input port 101a, and then passes through the pressing output active roller 104a and pressing output passive roller 104b of the fiber sliver output port 101b. The fiber strip passes through the tube and is then pressed down by external force onto the passive output roller 104b, thereby reducing the distance between the active output roller 104a and the passive output roller 104b until sufficient attraction is generated between the magnets on the first fixed sleeve 104c and the second fixed sleeve 104d. Under the action of attraction, the first fixed sleeve 104c and the second fixed sleeve 104d come into close contact with each other, thereby pressing the active output roller 104a and the passive output roller 104b tightly, which in turn presses the passing fiber strip tightly. The pressing points of the active output roller 104a and the passive output roller 104b on the fiber strip constitute the fiber strip output point.

[0042] The first motor 103 drives the drive cylinder 102 to rotate via a belt, which in turn drives the output disc 101 to rotate synchronously, which in turn drives the connecting shaft 107 to rotate synchronously, which in turn drives the pressing output active roller 104a to rotate via the bevel gear set 108, which in turn drives the pressing output passive roller 104b to rotate at the same speed but in the opposite direction, thereby enabling the pressing fiber strip to be continuously output.

[0043] At the same time, the output disc 101 rotates, which in turn drives the pressed fiber strip to rotate along the axial direction of the output disc 101, so that the fiber strip achieves twisting under the pressing action. The output fiber strip is continuously wound on the sliver tray 203a under the coordinated motion of the sliver tube 203 periodically reciprocating and stopping in the horizontal direction and continuously rotating in the circumferential direction.

[0044] Example 2

[0045] Reference Figures 1-7 This embodiment provides a control method based on the fiber sliver winding device in Embodiment 1. The control method includes:

[0046] S1: Twist and output the 104 pairs of fiber strips by pressing output.

[0047] Specifically, the first motor 103 drives the drive cylinder 102 to rotate via a belt, which in turn drives the output disc 101 to rotate synchronously, which in turn drives the connecting shaft 107 to rotate synchronously, which in turn drives the pressing output active roller 104a to rotate via the bevel gear set 108, which in turn drives the pressing output passive roller 104b to rotate at the same speed but in the opposite direction, thereby enabling the fiber strip to achieve twisting under the pressing action and to continuously output.

[0048] S2: The horizontal reciprocating motion and circular rotation motion of the strip tube 203 are performed simultaneously by the horizontal fixed plate 204 and the horizontal rotating plate 202a.

[0049] Specifically, the third motor 202b controls the rotation of the transverse fixed plate 204, which in turn controls the circumferential rotation of the strip tube 203 placed on the transverse fixed plate 204. The second motor 201d controls the rotation of the transverse moving rod 201c, which in turn drives the second pulley 201b, thereby controlling the transverse fixed plate 204 to perform horizontal reciprocating motion on the slide rail 201e.

[0050] At the same time, the output disc 101 is controlled to rotate, and the sliver can 203 moves back and forth periodically in the horizontal direction and stops moving, while rotating continuously in the circumferential direction, so that the fiber sliver is continuously wound around the sliver can 203a.

[0051] S3: This causes the fiber strip to form 300 turns of incised cotton sheet and 400 turns of all-cotton sheet in the strip tube 203.

[0052] First, it should be noted that, as Figure 3 As shown, the circle formed by several fiber strips looping 500 times and tangent to the inner wall of the sliver tube 203 is called the inscribed cotton sheet 300. (Example:) Figure 4 As shown, the circle consisting of several fiber strips wound around 500 and coinciding with the inner wall of the strip tube 203 is called the cotton sheet 400.

[0053] During the winding process of the inner-cut cotton sheet 300 times, the center of the horizontal moving fixing plate 204 is initially located at the set origin. The set origin ensures that the fiber strip output point and the inner side of the sliver tube 203 are vertically aligned. At this time, the point on the inner side of the sliver tube 203 that is vertically aligned with the fiber strip output point constitutes the inner tangent point between the inner-cut cotton sheet 300 and the sliver tube 203. At the same time, the point on the inner side of the sliver tube 203 that is vertically aligned with the fiber strip output point also constitutes the inner tangent point between the first fiber strip winding 500 and the inner-cut cotton sheet 300.

[0054] At this time, the output disc 101 rotates one circle, and simultaneously the second motor 201d drives the transverse rotating disc 202a to rotate at a certain angle, which in turn drives the sliver can 203 to rotate synchronously at a certain angle. The third motor 202b drives the second pulley 201b to move inward a certain distance through the transverse driving rod 201c, thereby causing the sliver can 203 to move synchronously a certain distance, and then forming the first fiber sliver loop 500 on the sliver holding disc 203a that is tangent to the inner-cut cotton sheet 300.

[0055] Reference Figure 3 After the first fiber strip loop 500 is formed, the fiber strip output point returns to the starting point, and the fiber strip output point is vertically aligned with the edge of the inner-cut cotton sheet 300. At this time, the point at the edge of the inner-cut cotton sheet 300, which is vertically aligned with the fiber strip output point, also constitutes the inner tangent point of the second fiber strip loop 500 and the inner-cut cotton sheet 300. At this time, the output disk 101 rotates one circle, and at the same time, the second motor 201d drives the sliver tube 203 to rotate a certain angle, and the third motor 202b drives the sliver tube 203 to move inward a certain distance, and then the second fiber strip loop 500, which is internally tangent to the inner-cut cotton sheet 300, is formed on the sliver holding disk 203a. This continues until the N1 / 2 or (N1+1) / 2 fiber strip loop 500, which is internally tangent to the inner-cut cotton sheet 300, is formed on the sliver holding disk 203a, where N1 is the designed loop ratio for forming an inner-cut cotton sheet 300.

[0056] At this point, the sliver can 203 moves inward to the furthest distance. Then, the second motor 201d drives the sliver can 203 to rotate at a certain angle, and the third motor 202b drives the sliver can 203 to move outward a certain distance. Then, the (N1 / 2)+1 or ((N1+1) / 2)+1 fiber sliver loop 500, which is tangent to the inner-cut cotton sheet 300, is formed on the sliver can 203a. This continues until the N1st fiber sliver loop 500, which is tangent to the inner-cut cotton sheet 300, is formed on the sliver can 203a, thus completing the first inner-cut cotton sheet 300 loop.

[0057] At this time, the strip tube 203 also completes a circular rotation and a horizontal reciprocating movement, and the center of the horizontal moving fixed plate 204 moves to the set origin.

[0058] Then the third motor 202b stops working, and the cotton sheet is wound 400 times, as per reference. Figure 4 During this process, the second motor 201d drives the sliver tube 203 to rotate at a constant speed n / N2, where n is the speed of the output disc 101, N2 is the designed loop ratio for forming a whole cotton sheet 400, and satisfies that N2 / N3 is an integer, and N3 is the number of in-cut cotton sheets 300 contained in one circumference of the designed sliver tube 203.

[0059] Continue until N2 / N3 fiber slivers are wound 500 times within the sliver tube 203, thus completing the first 400-turn winding of the cotton sheet. During the winding process, the sliver tube 203 rotates through 2π / N3 arcs.

[0060] Then continue with the second inner-cut cotton pad, making 300 turns, and the process of making the second inner-cut cotton pad 300 turns is consistent with the process of making the first inner-cut cotton pad 300 turns. Then make the second full cotton pad, making 400 turns, and the process of making the second full cotton pad 400 turns is consistent with the process of making the first full cotton pad.

[0061] This process continues until the N3-1th inner-cut cotton sheet is wound 300 times, and the N3-1th all-cotton sheet is wound 400 times, and finally the N3rd inner-cut cotton sheet is wound 300 times, thus completing the winding process of the fiber sliver along one circumference of the sliver can 203, as follows. Figure 5 .

[0062] The twisting continues until the fiber strip is completely wound within the entire canister 203. During the winding process, after the twisted fiber strip leaves the pressing point between the pressing output active roller 104a and the pressing output passive roller 104b, the applied twist will be released, causing the fibers in the fiber strip to undergo an unwinding movement in the opposite direction to the twisting direction.

[0063] As the fiber sliver is output, the unwinding process is gradually realized. At the same time, during the unwinding process, the fiber sliver will be coiled inside the sliver can 203, which will prevent part of the unwinding action. As a result, the fiber sliver is not completely unwound, so that part of the applied twist is retained, thereby achieving a partial twisting effect on the fiber sliver.

[0064] The fiber sliver wound on the sliver tray 203a exerts downward pressure on the second spring 203b under its own gravity, which in turn causes the sliver tray 203a to gradually descend, thus ensuring that the winding of the fiber sliver always occurs at the upper end of the sliver canister 203, thereby achieving stable winding of the fiber sliver.

[0065] To verify the beneficial effects of the present invention, the winding method of the present invention is now compared with the prior art. Specifically, refer to... Figure 6 , Figure 6 (a) and (c) are cross-sectional views of conventional winding with 12 layers and 21 layers, respectively. As can be seen from the figure, during the conventional winding process, the fiber strips are densely distributed in the center of the sliver 203. As the number of winding layers increases, the distribution range of the fiber strips remains unchanged, and the accumulation of fiber strips at the dense points is more severe. Figure 6(b) in the figure shows the 21-layer winding method of the present invention. As can be seen from the figure, the fiber strips in the winding method of the present invention have a wider distribution range in the sliver tube 203 and a more uniform distribution density, thereby making the dense distribution points of the fiber strips in conventional winding disappear.

[0066] Additionally, refer to Figure 7 , Figure 7 (d) and (e) are top views of the fiber slivers obtained by the conventional winding method and the winding method invented by our invention, respectively, within the sliver tube 203. Figure 7 In the conventional winding method shown in Figure (d), the coil ratio is 2:4, with 12 coils and a total winding length of 304m. The figure also shows that the fiber sliver distribution density within the sliver can is relatively dense.

[0067] And in Figure 7 In the winding method of the present invention shown in (e), the loop ratio of the inner-cut cotton sheet 300 is 24, and the loop ratio of the all-cotton sheet 400 is 24. The number of inner-cut cotton sheets 300 contained in one circumference is 8, with 12 layers wound, and the total winding length is 380m. It is easy to see that the distribution density of the fiber strips in the sliver tube is more uniform at this time.

[0068] In addition, taking the winding of a cotton fiber sliver with a linear density of 23 g / 5 m in a sliver tube with a diameter of 500 mm as an example, according to... Figure 7 The original winding method shown in (d) has a coil-to-strip ratio of 2:4 and a coil length of 3050m, according to... Figure 7 (e) shows the winding method of the present invention, with the output disc 101 having a diameter of 320 mm, the cotton sheet 400 having a diameter of 450 mm, and the winding length reaching 6030 meters, increasing the capacity by 97.7%.

[0069] In summary, by setting up a transverse fixed disk 204 that periodically reciprocates and stops along the horizontal direction while continuously rotating along the circumference, and an output disk 101 that maintains a constant speed rotation along the circumference, the present invention achieves a more uniform density distribution of the fiber sliver within the sliver can, thereby significantly increasing the sliver can capacity.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
