Description

Technical Field

[0001] This utility model relates to the technical field of yarn twisting devices, and more specifically, to twisting discs and straight twisting machines. Background Technology

[0002] In the textile industry, the straight twisting machine is the core equipment for achieving efficient yarn twisting. Its characteristic of "achieving two twisting processes in one operation" significantly improves production efficiency. To further optimize energy consumption during production, the industry commonly adopts an energy-saving solution called "shrinking yarn air pockets." This solution controls the yarn fed by the motor to the twisting device within a fixed area of ​​the twisting disc, reducing ineffective expansion of the yarn air pockets and thus lowering the equipment's operating energy consumption.

[0003] However, because the yarn needs to be fed within the fixed area of ​​the twisting disc for an extended period, continuous and concentrated friction occurs between the yarn and the disc surface. Over time, this friction causes grooves or indentations to form on the disc surface. These indentations disrupt the smooth path of the yarn, leading to wear and breakage as the yarn passes through these areas, resulting in fuzz. Fuzz not only directly affects key quality indicators such as yarn strength and evenness but can also cause problems like yarn breakage and fabric defects in subsequent weaving processes, severely restricting product quality stability.

[0004] These problems urgently need to be solved, therefore this utility model provides a twisting disc and a straight twisting machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a twisting disc and a straight twisting machine that are simple in structure, low in cost and can effectively avoid the formation of dents on the surface of the twisting disc due to friction.

[0006] The technical solution adopted by this utility model to solve its technical problem is: On the one hand, a twisting disc is provided, wherein the outer ring of the twisting disc is grooved to provide a guide wire groove, and the guide wire groove is provided with a yarn guide or a ceramic coating.

[0007] In this embodiment, specifically, the yarn guide is made of ceramic material or wear-resistant material.

[0008] In this embodiment, specifically, the wire groove has a "V" shaped structure.

[0009] In this embodiment, specifically, the wire groove is a "U" shaped structure.

[0010] In this embodiment, specifically, the yarn guide is semi-circular and is fixed in the wire groove.

[0011] In this embodiment, specifically, the inner ring of the twisting disc is provided with the fixing hole, which is used to fix the twisting disc.

[0012] On the other hand, a straight twisting machine is also provided, including the twisting disc described in any of the above claims.

[0013] In this embodiment, specifically, the straight twisting machine further includes a twisting device, a yarn bobbin, a yarn storage tray, and a motor. The motor is used to rotate the yarn output. The yarn is drawn out from the yarn bobbin and passes through the side of the yarn storage tray and the guide groove in sequence to enter the twisting device for twisting.

[0014] In this embodiment, specifically, the straight twisting machine further includes a take-up drum and a yarn guide nozzle. The yarn is wound into the take-up drum, and the yarn guide nozzle can move back and forth to evenly wind the yarn onto the take-up drum.

[0015] In this embodiment, specifically, the yarn is drawn out from the yarn storage tray, passes through the guide groove, is twisted at the twisting device, and finally wound into the take-up drum by the guide member.

[0016] The beneficial effects of this utility model are as follows: The outer ring of the twisting disc of this utility model is grooved with a guide wire groove, and the guide wire groove is provided with a yarn guide or a ceramic coating. When the straight twisting machine is running, the motor conveys the yarn to the twisting device. The yarn first enters the guide wire groove on the twisting disc. The twisting disc ensures that the yarn always keeps in contact with the wear-resistant guide wire or ceramic coating, and no longer directly rubs against the surface of the twisting disc, avoiding the formation of indentations on the surface of the twisting disc due to friction, ensuring smooth yarn transmission, and effectively reducing yarn wear and breakage.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1-4 As shown, this utility model provides a straight twisting machine 100 for twisting yarn 9. The straight twisting machine 100 includes a take-up bobbin 1, a yarn guide nozzle 2, a twisting device 3, an inner yarn tensioner 4, a raw yarn bobbin 5 for placing the yarn 9 to be twisted, a twisting disc 6, a yarn storage disc 7, and a motor 8.

[0022] In this embodiment, specifically, the yarn guide nozzle 2 can move back and forth along the axial direction of the take-up drum 1 to guide the twisted yarn 9 to be evenly distributed on the surface of the take-up drum 1.

[0023] In this embodiment, specifically, the yarn storage tray 7 has a yarn guide hole (not shown in the figure) on its side, which is used to temporarily store the yarn 9, buffer the speed difference between the yarn release of the raw yarn spool 5 and the twisting of the twisting device 3, and prevent the yarn 9 from breaking due to sudden tension changes.

[0024] In this embodiment, specifically, the inner yarn tensioner 4 is installed at the inlet end of the twisting device 3 and adopts a magnetic tension adjustment structure. The tension of the yarn is monitored in real time by a pressure sensor and the tension is automatically adjusted to ensure that the tension of the yarn 9 is uniform during the twisting process and to improve the twist stability.

[0025] In this embodiment, specifically, during the twisting process of the straight twisting machine 100, one yarn 9 is conveyed through the original yarn bobbin 5, the yarn storage tray 7, the twisting tray 6, and the twisting device 3, while the other yarn 9 is conveyed through the original yarn bobbin 5, the inner yarn tensioner 4, and the twisting device 3. The two yarns 9 enter the yarn guide nozzle 2 together under the twisting of the twisting device 3, and are finally wound into the take-up drum 1.

[0026] In this embodiment, specifically, the twisting disc 6 has a circular structure. The inner ring of the twisting disc 6 has a through hole 61, which is circular and used to fix the twisting disc 6 to the yarn storage disc 7, ensuring the stability of the twisting disc 6 during equipment operation and preventing yarn conveying deviation due to vibration. The motor 8 rotates to drive the yarn 9 out of the bobbin 5. In this embodiment, specifically, the outer ring of the twisting disc 6 has a slotted guide groove 62, which is an open-type groove structure. A yarn guide 63 is provided inside the guide groove 62.

[0027] In this embodiment, specifically, the wire groove 62 includes a "U" shaped structure and a "V" shaped structure.

[0028] In this embodiment, specifically, the bottom of the "U"-shaped guide groove 62 is a smooth arc shape, which can provide stable support for the yarn 9, prevent the yarn from breaking due to local stress concentration during transmission, and reduce the contact wear between the yarn and the groove wall.

[0029] In this embodiment, specifically, the "V"-shaped guide groove 62 has a groove width greater than the diameter of the yarn 9. Through the constraint of the groove wall, the yarn is guided and gathered to prevent it from splitting or deviating from the groove body during transmission.

[0030] In this embodiment, specifically, the yarn guide 63 is installed and fixed in the wire guide groove 62. The yarn guide 63 is fixed in the wire guide groove 62 by embedding or bonding, and the yarn 9 can directly contact and be conveyed with the yarn guide 63.

[0031] In this embodiment, specifically, the yarn guide 63 is made of ceramic material or wear-resistant material.

[0032] In this embodiment, specifically, the ceramic coating is attached to the inner wall of the wire guide groove 62. In this embodiment, specifically, the motor 8 is used to rotate the yarn output. The yarn 9 is drawn out from the original yarn bobbin 5, passes through the side of the yarn storage tray 7 and the wire guide groove 62 in sequence, and enters the twisting device 3 for twisting. The twisted yarn 9 is evenly wound onto the take-up drum 1 by the take-up member 2. The yarn guide nozzle 2 can move back and forth to ensure that the yarn 9 is evenly wound onto the take-up drum 1.

[0033] The working process of this twisting disc: When the straight twisting machine 100 is running normally, the motor 8 feeds the yarn 9 to the twisting device 3. The yarn 9 first enters the yarn guide groove 62 on the twisting disc 6. A yarn guide element 63 is provided inside the yarn guide groove 62. The yarn 9 will pass through the inner hole channel of the yarn guide element 63. If the inner side of the yarn guide groove 62 is coated with a ceramic coating, the yarn 9 will contact the surface of the ceramic coating. During this process, the yarn always maintains contact with the yarn guide element 63 or the ceramic coating and no longer directly rubs against the surface of the twisting disc.

[0034] The beneficial effects of this utility model of twisting disc and straight twisting machine are as follows: 1. The yarn guide ceramic part 63 or ceramic coating is provided in the guide groove 62 of the twisting disc 6. Both have high wear resistance and low surface roughness, which can change the yarn 9 from "direct friction with metal" to "contact with wear-resistant materials", avoid the twisting disc 6 from forming dents due to long-term friction, and reduce the fiber snagging and breakage of the yarn 9, thereby reducing the fuzz production rate from the root.

[0035] 2. The guide groove 62 of the twisting disc 6 adopts an open groove design, and the yarn 9 can be directly put into the groove from the top, which shortens the yarn threading operation time. It is especially suitable for batch yarn threading of multi-spindle straight twisting machine 100 and reduces the labor intensity of operators.

[0036] 3. The yarn guide ceramic component 63 is fixed by an inlay. If wear occurs, only the yarn guide component 63 needs to be replaced, without replacing the entire twisting disc 6. The ceramic coating surface is smooth and highly wear-resistant, reducing the replacement frequency of the twisting disc 6 and lowering equipment maintenance costs.
