Description

Technical Field

[0001] The embodiments of the present application relate to the field of textile technology, and in particular to a twisting device and a control method. Background Art

[0002] In order to turn the fibers into yarns during the spinning process, twisting is a necessary technical method. Before twisting, the discrete fibers are generally gathered into fiber strips through a carding machine or combing machine. After twisting, the outer fibers of the fibers are squeezed toward the inner layer to generate centripetal pressure, thereby making the slivers obtain friction along the length direction of the fibers. In the roving process, the stretched sliver is given appropriate twist to make the yarn have a certain strength, which is conducive to the winding of coarse yarn and the unwinding of fine yarn. The twisting process of the roving frame is generally achieved by a twister at the top of the spindle of the roving frame. The twister increases the friction between the yarn and the top in the circumferential direction while maintaining the normal axial movement of the yarn, causing the yarn to roll on the surface of the top hole of the spindle to produce twist. In the spun yarn process, the twisted yarn has certain physical and mechanical properties such as strength, elasticity, gloss and feel.

[0003] The main indicators that indicate the degree of yarn twist are twist, twist angle, twist width and twist coefficient. The indicator that indicates the twist direction is called twist direction.

[0004] Twist refers to the 360° angular displacement between two sections of a yarn, known as a twist, commonly referred to as one turn. The number of twists per unit length of yarn is called twist. In my country, twist is measured in Tex counts for cotton yarn, expressed as the number of twists per 10cm of yarn. Worsted wool yarn and chemical filament yarns use metric counts, expressed as twists per meter. Twist is also measured in Imperial counts, expressed as twists per inch.

[0005] Twist angle refers to the fact that before twisting, the fibers in a yarn are parallel to each other, but after twisting, the fibers tilt. The greater the twist, the greater the fiber tilt. The degree of twist can be expressed by the twist angle β, the angle at which the fibers tilt within the yarn. Two yarns with the same twist will have different degrees of twist due to their different thicknesses. The thicker the yarn, the greater the twist and the larger the twist angle β.

[0006] Twist width means that if the yarn cross section is regarded as a circle, the angles between the fibers at different radii and the yarn axis are different. In order to express this situation, the twist width indicator is introduced.

[0007] Twist coefficient refers to the fact that twist cannot be used to compare the degree of twist in yarns of different thicknesses, as the fibers of a thicker yarn with the same twist will tilt more than those of a thinner yarn. In actual production, twist coefficient is often used to indicate the degree of twist in a yarn. Twist coefficient is a relative value expressed in relation to linear density and can be used to compare the degree of twist in yarns of different thicknesses. Twist coefficient can be calculated based on the twist and linear density of the yarn.

[0008] Twist refers to the tilt of the fibers in a single yarn or the yarns in a ply yarn after twisting. It can be divided into two types: Z twist and S twist. After twisting, the twist direction of the yarn filaments from the lower right corner to the upper left corner, with the tilt aligned with the middle of the "S", is called S twist or forward twist. The twist direction of the yarn from the lower left corner to the upper right corner, with the tilt aligned with the middle of the "Z", is called Z twist or reverse twist. Generally, Z twist is used for single yarns, and S twist is used for ply yarns.

[0009] The existing twisting mechanism requires many parts to be replaced to adjust the twist, which is complicated to operate and has low efficiency. Summary of the Invention

After being guided by the fiber guide port 330, the twister 340 rotates at a high speed under the drive of the first twisting motor 310. The fiber strip 500 is twisted when passing through the twister 340 and stored in the storage assembly 400. The twisting device provided in the embodiment of the present application has few parts that need to be adjusted and replaced, is simple to operate, and has high efficiency.

[0070] like Figure 4 As shown, in a feasible embodiment, the twisting assembly 300 also includes: a top cover 320, the top cover 320 is arranged on the top of the first twisting motor 310; a first sensor 360 and a first bracket 350, the first bracket 350 is connected to the frame assembly 100, and the first sensor 360 is arranged on the first bracket 350; a first detection piece 370, the first detection piece 370 is arranged on the edge of the twister 340, and the detection direction of the first sensor 360 is toward the first detection piece 370.

[0071] like Figure 4As shown, in this technical solution, the structural composition of the twisting assembly 300 is further provided, and the twisting assembly 300 includes: a first twisting motor 310 is arranged on the upper part of the twister 340, for driving the twister 340 to rotate; a top cover 320 is arranged above the first twisting motor 310, and is connected to the top of the moving part 210 of the drafting assembly 200 when installed, for sealing and dustproofing; a fiber guide port 330 is arranged on the top of the twister 340, and is connected to the top of the twister 340 through the center hole of the top cover 320 when installed; the twister 340 Located at the bottom of the twisting assembly 300, it is used to twist the fiber strip 500; the first bracket 350 is arranged on the upper surface of the car surface 120 of the frame assembly 100, close to the outer edge of the twister 340, and is used to connect the first sensor 360; the first sensor 360 is arranged on the first bracket 350, and is used to detect and monitor the operating status of the twister 340; the first detection piece 370 is arranged on the outer edge of the twister 340, and is used to provide a detection signal to the sensor, which facilitates the control of the twisting assembly 300 and the acquisition of the operating status of the twisting assembly 300.

[0072] In a feasible embodiment, the twister 340 is detachably connected to the frame assembly 100, and the twister 340 includes: a Z-twist twister 340A and an S-twist twister 340B, one of the Z-twist twister 340A and the S-twist twister 340B is connected to the frame assembly 100; wherein, the Z-twist twister 340A includes: a first twister body 341, a Z-twist twisting tube 344 and a Z-twist covering layer 345, the Z-twist twisting tube 344 is connected to the first twister body 341, and the Z-twist covering layer 345 is covered on the first twister body 341; wherein, the S-twist twister 340B includes: a second twister body 346, an S-twist twisting tube 342 and an S-twist covering layer 343, the S-twist twisting tube 342 is connected to the second twister body 346, and the S-twist covering layer 343 is covered on the second twister body 346.

[0073] In this technical solution, a style of a twister 340 is further provided. The twister 340 may include two types of twisters 340, namely a Z twister 340A and an S twister 340B. The Z twister 340A and the S twister 340B may be selectively connected to the twisting assembly 300 based on actual needs. The twisting direction is determined by the twisting tube configured by the twister 340, such as Figure 8a and Figure 8bAs shown, the twister 340 is classified into two types, a Z-twist twister 340A and an S-twist twister 340B. The Z-twist twister 340A is composed of a first twister body 341, a Z-twist twisting tube 344 and a Z-twist covering layer 345. Due to the configuration of the Z-twist twisting tube 344, the use of this twister 340 will achieve Z-twist twisting. The S-twist twister 340B is composed of a second twister body 346, an S-twist twisting tube 342 and an S-twist covering layer 343. Due to the configuration of the S-twist twisting tube 342, the use of this twister 340 will achieve S-twist twisting. When using the twisting device proposed in this embodiment, when changing the twisting direction, only the twister 340 needs to be replaced, which is simple and efficient to operate. In addition, the Z-twist twister 340A and the S-twist twister use the same twister 340 body, which has high parts commonality and reduces maintenance and servicing costs.

[0074] like Figure 2 As shown in a feasible embodiment, the frame assembly 100 includes: a chassis 110; a first box body 130 and a second box body 140, the first box body 130 and the second box body 140 are connected to the chassis 110; a vehicle surface 120, the vehicle surface 120 is connected to the first box body 130 and the second box body 140, the drafting assembly 200 and the twisting assembly 300 are arranged on the vehicle surface 120, and the storage assembly 400 is arranged at the bottom of the vehicle surface 120.

[0075] In this technical solution, the structure of a frame assembly 100 is further provided, and a chassis 110 is used to support the entire device; a car surface 120 is arranged on the top of the frame assembly 100, and is used to support and fix the drafting assembly 200 and the twisting assembly 300; a first box body 130 is arranged between the chassis 110 and the car surface 120, and is located on the left side of the frame assembly 100, and is used to support the car surface 120 and accommodate electrical and pneumatic components; a second box body 140 is arranged between the chassis 110 and the car surface 120, and is located on the right side of the frame assembly 100, and is used to support the car surface 120 and accommodate electrical and motor components. This arrangement makes the structural layout of the twisting device more compact.

[0076] like Figure 3 As shown, in a feasible embodiment, the stretching assembly 200 includes: a moving part 210, the moving part 210 is connected to the car surface 120 of the frame assembly 100; an unfolder 240, a stretching mechanism 230 and a pressure roller mechanism 220 are arranged on the side of the moving part 210, and the output end of the pressure roller mechanism 220 is facing the twisting assembly 300.

[0077] This technical solution further provides the structural composition of the drafting assembly 200, which includes: a moving member 210 for supporting the drafting assembly 200 and located below the drafting assembly 200; a drafting mechanism 230 disposed at the top of the drafting assembly 200; a pressure roller mechanism 220 disposed in front of the drafting mechanism 230; and an expander 240 disposed behind the drafting mechanism 230. The limiter passes through the expander 240, the drafting mechanism 230, and the pressure roller mechanism 220 in sequence. First, the drafting mechanism 230, which is arranged in a roughly horizontal direction, drafts the fiber strip 500. After drafting, the pressure roller mechanism 220 changes the output direction of the fiber strip 500 to a vertical direction, moving it toward the top entrance of the twister 340. The pressure roller mechanism 220 controls the conveying speed of the fiber strip 500 and determines the twisting parameters based on this speed.

[0078] After leaving the pressing roller mechanism 220, the fiber strip 500 first enters the fiber guide opening 330. The function of the fiber guide opening 330 is to control the movement direction of the fiber strip 500 and ensure that the fiber strip 500 enters the twister 340 completely under the constraint of the outer edge of the fiber guide opening 330. After entering the twister 340, the fiber strip 500 will be subjected to a large centrifugal force due to the high-speed rotation of the twister 340. Under the action of the centrifugal force, the fiber strip 500 will move in the circumferential direction. Therefore, only under the constraint of the fiber guide opening 330 can the fiber strip 500 be guaranteed to leave the pressing roller mechanism 220 and enter the twister 340 completely.

[0079] After the fiber strip 500 enters the twister 340, it first enters the inlet end of the twisting tube. When the twister 340 rotates at high speed, the fiber strip 500 moves toward the outlet end of the twisting tube under the guidance of the twisting tube, and then is output from the outlet end of the twisting tube, completing the twisting process in the twister 340 and leaving the twister 340 from the outlet end of the twisting tube.

[0080] like Figure 5 As shown, in a feasible embodiment, the storage component 400 includes: a storage 410, a cover 420, a tray 430 and a base 450, the base 450 is connected to the rack assembly 100, the storage 410 is set on the base 450, the cover 420 is set on the top of the storage 410, the tray 430 is set on the cover 420, and the tray 430 is connected to the storage 410.

[0081] like Figure 6 and Figure 7 As shown, in a feasible embodiment, the storage 410 includes a first cylinder 411 and a second cylinder 412 , and a gap is formed between the first cylinder 411 and the second cylinder 412 , and the gap is used to accommodate the fiber strip 500 .

[0082] like Figure 9a and Figure 9b As shown, in some examples, the storage 410 adopts a double-wall structure, and the twisted fiber strip 500 is stored in the storage 410 in a spiral shape, and the position of the fiber strip 500 is constrained by the first cylinder 411 and the second cylinder 412. Using this storage 410 requires that the twister 340 is arranged concentrically with the storage 410, and the output Rj of the twister 340 (such as Figure 10 The advantages of these memories 410 are that the fiber strips 500 are placed in a regular circle, without local stacking, without accidental pulling, and the tension of the fiber strips 500 is stable. The quality of the subsequent fiber strips 500 when taken out of the memory 410 is stable and efficient. The disadvantage is that the storage capacity is small.

[0083] In a feasible embodiment, a first connecting hole 421 is formed on the cover plate 420, and the cover plate 420 is connected to the frame assembly 100 through the first connecting hole 421; a second connecting hole 432 and a limiting hole 431 are formed on the tray 430, and the tray 430 is connected to the first twisting motor 310 through the second connecting hole 432, and the limiting hole 431 is used to limit the casters of the storage device 410.

[0084] In some examples, the shape of the limiting hole 431 can be an oblong, circular or polygonal, and the limiting hole 431 limits the position of the bottom caster of the storage 410, so that the storage 410 rotates together with the second twisting motor 440 when driven by the second twisting motor 440.

[0085] In a feasible embodiment, the storage component 400 also includes: a second twisting motor 440, the second twisting motor 440 is arranged on the base 450; a connecting column 451, the connecting column 451 is connected to the cover 420 and the base 450; a second sensor 460 and a second bracket 470, the second bracket 470 is connected to the base 450, and the second sensor 460 is arranged on the second bracket 470; a second detection piece 480, the second detection piece 480 is arranged on the edge of the second twisting motor 440, and the detection direction of the second sensor 460 is toward the second detection piece 480.

[0086] In this technical solution, the structural composition of the storage component 400 is further provided, and the storage component 400 includes: a storage 410 is arranged above the storage component 400 and below the twisting component 300, for storing the fiber strips 500 output from the twister 340; a cover plate 420 is arranged below the storage 410 and is connected to the upper surface of the base 450 when installed for dust prevention; a tray 430 is arranged above the second twisting motor 440 and below the storage 410, and is connected to the upper surface of the second twisting motor 440 when installed; the second twisting motor 440 is arranged Inside the base 450, it is used to drive the storage 410 to rotate through the tray 430; the base 450 is arranged inside the chassis 110, for supporting and fixing the storage assembly 400; the second sensor 460 is arranged on the second bracket 470, for detecting and monitoring the operating status of the second twisting motor 440; the second bracket 470 is arranged inside the base 450, close to the outer edge of the twister 340, for connecting the second sensor 460; the second detection piece 480 is arranged on the outer edge of the second twisting motor 440, for providing a detection signal to the second sensor 460.

[0087] After leaving the twister 340, the fiber strip 500 enters the storage 410 of the storage assembly 400. A second twisting motor 440 is provided in the storage assembly 400. The top rotating end of the second twisting motor 440 is connected to the tray 430. A limiting hole 431 is provided on the upper surface of the tray 430. When the storage 410 is placed above the tray 430, the casters at the bottom of the storage 410 will enter the limiting hole 431 area. At this time, the movement and rotation of the storage 410 will be constrained. In this case, the rotation of the second twisting motor 440 will drive the tray 430, and the tray 430 will drive the storage 410 to rotate synchronously to complete the storage assembly 400 to store and twist the fiber strip 500. The twist formed by the fiber strip 500 stored in the storage 410 is a synthetic twist formed by the joint action of the twisting assembly 300 and the storage assembly 400.

[0088] In some examples, the first twisting motor 310 and the second twisting motor 440 both use disc motors. Due to the characteristics of the disc motors themselves, the twisting assembly 300 and the storage assembly 400 have the characteristics of compact structure, small size, and easy installation.

[0089] In some examples, the first twisting motor 310 employs a hollow rotor structure, facilitating the installation and placement of the twister 340. Because the first twisting motor 310 employs a hollow rotor structure, the top portion of the twister 340 is fully inserted into the hollow hole of the first twisting motor 310, reducing the overall installation height of the twisting assembly 300. Furthermore, the reduced height of the twister 340 also reduces its moment of inertia, thereby reducing the rated power of the first twisting motor 310 and making the twisting device more energy-efficient and environmentally friendly.

[0090] In some examples, the second twisting motor 440 adopts a hollow rotor weight reduction measure, thereby reducing the rated power of the second twisting motor 440, making the twisting device more energy-efficient and environmentally friendly.

[0091] In some examples, the twisting assembly 300 is provided with a top cover 320. In some feasible instances, the top cover 320 is connected to the top of the moving part 210. The hollow hole of the top cover 320 can accommodate the outer circle of the fiber guide port 330 and retain a certain gap, which is generally between 0.5 and 2 mm. Such an arrangement of the top cover 320 can form a good sealing effect between the first twisting motor 310 and the fiber guide port 330, ensuring continuous and stable operation of the first twisting motor 310.

[0092] In some examples, the twister 340 is provided with a covering layer. In some feasible instances, the covering layer is commonly made of stainless steel plate with a thickness of 0.5 to 2 mm, which is covered on the bottom and side outer surfaces of the twister 340. The smooth surface of the covering layer can effectively protect the fiber strips 500 in the storage device 410, reduce the maintenance cost of the twister 340, and increase its service life.

[0093] In some examples, a rotation speed sensor is provided on the pressure roller mechanism 220 to monitor the rotation speed of the pressure roller.

[0094] In summary, in the twisting device provided by the embodiment of the present application, the pressure roller mechanism 220 rotates at a set speed to monitor the length of the output fiber strip 500, the first twisting motor 310 drives the twister 340 to rotate to synthesize the head end twisting speed of the fiber strip 500, and the second twisting motor 440 drives the tray 430 and then drives the storage device 410 to synthesize the end twisting speed of the fiber strip 500. The twist control of the fiber strip 500 is finally completed through the speed of the pressure roller mechanism 220 and the three speed synthesis settings of the two twisting motors; the twist direction control is determined by the type of the twister 340 (Z twist twister 340A and S twist twister 340B), and adjusting the twist direction only requires replacing one part of the twister 340. It has a simple structure and is easy to operate. It can quickly adjust the twist, reduce labor intensity, and improve production efficiency.

[0095] like Figure 13 As shown, according to the second aspect of the embodiment of the present application, a control method is proposed, which is applied to the twisting device as any of the above technical solutions. The control method includes:

[0096] Step 201: determining the distance between the center of the twister and the center of the storage device based on the diameter of the first cylinder, the gap between the fiber strip and the first cylinder, and the diameter of the fiber strip output by the twister;

[0097] Step 202: Based on the diameter of the pressing roller of the pressing roller mechanism, the speed of the pressing roller and the required twist, the speed of the first twisting motor and the second twisting motor are determined.

[0098] The control method provided in the embodiment of the present application is applied to the twisting device of any of the above technical solutions, so the control method has all the beneficial effects of the twisting device of the above technical solutions.

[0099] The control method provided in the embodiment of the present application determines the distance between the center of the twister and the center of the storage device based on the diameter of the first cylinder, the gap between the fiber strip and the first cylinder, and the diameter of the fiber strip output by the twister. Specifically, a small twister output can be used, and the output fiber strip is stored in the storage device. Figure 11 The use of this twister requires reasonable setting of relevant parameters to ensure that the twisted fiber strips are Figure 11 Correct storage position as shown.

[0100] Figure 11 The meanings of the symbols are as follows:

[0101] Dc——diameter of the first cylinder

[0102] Dj——diameter of fiber strip output by twister

[0103] S——Gap between fiber strip and first cylinder

[0104] L——The distance between the twister center and the storage center

[0105] The basic process of determining each parameter is as follows: First, determine the first cylinder diameter Dc based on the fiber strip output diameter Dj of the twister used, and generally require Dc≈3Dj~8Dj; then determine S, and determine S based on the type, diameter, and quantity of the fiber strip. The general selection range of S is 5mm~20mm.

[0106] Finally, the L value is calculated according to the formula:

[0107] L=Dc / 2-S-Dj / 2.

[0108] Furthermore, a large twister can also be used for output, and the output fiber strips are stored in the memory to achieve the effect as follows: Figure 12 The use of this twister requires reasonable setting of relevant parameters to ensure that the twisted fiber strips are Figure 12 Correct storage position as shown.

[0109] Figure 12 The meanings of the symbols are as follows:

[0110] Dc——diameter of the first cylinder

[0111] Dj——diameter of fiber strip output by twister

[0112] S——Gap between fiber strip and first cylinder

[0113] L——The distance between the twister center and the storage center

[0114] The basic process of determining each parameter is as follows: First, determine the first cylinder diameter Dc based on the fiber strip output diameter Dj of the twister used, and generally require Dc≈1.4j~1.85Dj; then determine S later, and determine S based on the type, diameter, and quantity of the fiber strip. The general selection range of S is 5mm~20mm.

[0115] Finally, the L value is calculated according to the formula:

[0116] L=Dc / 2-S-Dj / 2.

[0117] Furthermore, the control method provided in the embodiment of the present application determines the twist based on the twister speed, the storage speed, the roller diameter and the roller speed of the pressure roller mechanism. Specifically, the synthetic twist calculation process of the twisting device is as follows:

[0118] Nt=100(nj+nc) / (πDyny)

[0119] Ng=10Nt

[0120] The meanings of the letters in the formula are as follows:

[0121] Nt——Twist number, number of twists / 10cm

[0122] Ng——Twist in metric count, number of twists / m

[0123] Dy——diameter of pressure roller, mm

[0124] ny——roller speed, rpm

[0125] nj——twister speed, rpm

[0126] nc——memory speed, rpm

[0127] In summary, the twisting device provided in the embodiment of the present application is combined with a control method. The pressure roller mechanism rotates at a set speed to monitor the length of the output fiber strip. The first twisting motor drives the twister to rotate to synthesize the twisting speed of the fiber strip at the first end. The second twisting motor drives the tray and then drives the storage device to synthesize the twisting speed of the fiber strip at the end. The twist control of the fiber strip is finally completed by setting the speed of the pressure roller mechanism and the three speeds of the two twisting motors. The twist direction control is determined by the type of twister (Z twist twister and S twist twister). Adjusting the twist direction only requires replacing one part of the twister. It has a simple structure and is easy to operate. It can quickly adjust the twist, reduce labor intensity, and improve production efficiency.
