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, the disc surface easily develops grooves or indentations due to yarn friction wear. These indentations disrupt the smooth yarn feed path, causing yarn wear and breakage as it passes through the indented areas, resulting in fuzz. Fuzz not only directly affects key quality indicators such as yarn strength and evenness, but can also lead to problems like yarn breaks and fabric defects in subsequent weaving processes, severely restricting product quality stability and impacting production efficiency.

[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 perforated and a wire hole is provided, and the wire hole 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 yarn guide is installed and fixed in the wire hole.

[0009] 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.

[0010] On the other hand, a straight twisting machine is also provided, including the twisting disc described in any of the above claims.

[0011] In this embodiment, 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.

[0012] 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.

[0013] In this embodiment, specifically, the yarn is drawn out from the yarn storage tray, passes through the wire hole, is twisted at the twisting device, and finally is wound into the take-up drum by the take-up member.

[0014] The beneficial effects of this utility model are as follows: The outer ring of the twisting disc of this utility model is provided with a wire hole, and the wire hole is provided with a yarn guide or a ceramic coating. When the straight twisting machine is running, the motor delivers the yarn to the twisting device. The yarn first enters the yarn guide groove on the twisting disc.

[0018] 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.

[0019] like Figure 1-3 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] In this embodiment, specifically, the twisting disc 6 has a circular structure, and the inner ring of the twisting disc 6 has a fixing hole 61. The fixing hole 61 is circular and is used to fix the twisting disc 6 on the yarn storage disc 7 to ensure that the twisting disc 6 is stable in position during equipment operation and to avoid yarn conveying deviation due to vibration. The motor 8 rotates to drive the yarn 9 in the original yarn drum 5 out of the yarn.

[0025] In this embodiment, specifically, the outer ring of the twisting disc 6 is perforated with a wire hole 62, and the wire hole 62 is provided with a yarn guide 63 or a ceramic coating.

[0026] In this embodiment, specifically, the yarn guide 63 is made of ceramic material or wear-resistant material.

[0027] In this embodiment, the yarn guide 63 is specifically installed and fixed in the wire hole 62.

[0028] In this embodiment, specifically, the ceramic coating is attached to the inner wall of the wire hole 62.

[0029] In this embodiment, specifically, the motor 8 is used to rotate the yarn output. The yarn 9 is drawn out from the original yarn spool 5, passes through the side of the yarn storage tray 7 and the wire hole 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.

[0030] The working process of this twisting disc: When the straight twisting machine 100 is running normally, the yarn 9 first enters the yarn guide hole 62 on the twisting disc 6. A wear-resistant yarn guide element 63 is installed inside the yarn guide hole 62. The yarn 9 passes through the inner channel of the wear-resistant yarn guide element 63. If the inner side of the yarn guide hole 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 wear-resistant yarn guide element 63 or the ceramic coating, and no longer directly rubs against the surface of the twisting disc.

[0031] The beneficial effects of this utility model of twisting disc and doubling twister are: 1. The conductor hole 62 of the twisting disc 6 is provided with a wear-resistant yarn guide 63 or has an attached ceramic coating. When the yarn 9 is conveyed, it is always in contact with the inner hole channel of the wear-resistant yarn guide 63 or the surface of the ceramic coating, rather than directly rubbing against the surface of the twisting disc. This greatly reduces the wear of the yarn, effectively protects the original quality of the yarn, and reduces yarn damage caused by friction.

[0032] 2. The twisting disc 6 is equipped with a wire guide hole 62, which can stably limit the yarn 9 within the hole and prevent the yarn from shifting during the conveying and twisting process. At the same time, the twisting disc 6 is fixed to the yarn storage disc 7 through the fixing hole 61, which can avoid the twisting disc position shifting due to equipment vibration, further ensuring the accuracy of the yarn conveying path and reducing quality problems caused by displacement.
