Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to a yarn reversing component, a yarn reversing device and a yarn doubling machine. BACKGROUND

[0002] A spinning frame can directly produce a strand by doubling and twisting wool yarn and filament. The diversity of filaments results in different sizes and shapes of yarn bobbins, which cannot meet the production needs of the spinning frame. Therefore, the filaments need to be reversed, and the filaments need to be reorganized and prepared so that the yarn is wound on a reversing bobbin with uniform specifications, thereby ensuring the smooth progress of the subsequent textile process. For example, the Chinese patent document CN202744097U discloses a mercerized cotton hank reversing machine, which can automatically wind the mercerized cotton hank into a winding container through a hank rotating frame and the winding container.

[0003] The yarn reversing component in the prior art has the following problems: if the reversing bobbin and the yarn reversing component are not tightly installed, the reversing bobbin and the yarn reversing component are prone to relative rotation due to slippage during the reversing process, which causes the yarn to relax and further affects the subsequent textile process; if the reversing bobbin and the yarn reversing component are too tightly installed, the reversing bobbin is difficult to be removed from the yarn reversing component. SUMMARY

[0004] In order to solve the problems of the prior art, the present application aims to provide a yarn reversing component, a yarn reversing device and a yarn doubling machine, which can firmly install the reversing bobbin and the yarn reversing component and prevent relative rotation, and can conveniently remove the reversing bobbin from the yarn reversing component.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: the present application provides a yarn reversing component, which comprises: a yarn bobbin mounting roller and a mouth ring, the yarn bobbin mounting roller is provided with a doubling bobbin mounting portion at each of the opposite ends in the axial direction, the inner diameter of the doubling bobbin mounting portion is equal to the outer diameter of the doubling machine doubling bobbin, the middle part of the yarn bobbin mounting roller is provided with a reversing bobbin mounting portion, the diameter of the reversing bobbin mounting portion is slightly smaller than the inner diameter of the reversing bobbin, and a ring-shaped O-ring mounting groove is arranged on the reversing bobbin mounting portion; an O-ring is mounted in the O-ring mounting groove, the outer diameter of the O-ring is greater than the inner diameter of the reversing bobbin, and the width of the O-ring mounting groove is greater than the width of the O-ring, so that the O-ring can be turned over and moved along the width direction of the O-ring mounting groove when the reversing bobbin is mounted or removed.

[0006] As a preferred technical solution, a limiting step portion is further arranged on the yarn bobbin mounting roller, the limiting step portion is arranged at one end of the reversing bobbin mounting portion, and the outer diameter of the limiting step portion is greater than the inner diameter of the reversing bobbin.

[0007] As a preferred technical solution, the rewinding drum mounting part is provided with a guide part at the end away from the limiting step part, and the diameter of the guide part decreases from the middle of the rewinding drum mounting part to the end of the rewinding drum mounting part.

[0008] As a preferred technical solution, the width of the O-ring mounting groove is greater than or equal to one-third of the width of the thread-reversing drum mounting part, and the width of the O-ring mounting groove is less than or equal to two-thirds of the width of the thread-reversing drum mounting part.

[0009] As a preferred technical solution, one O-ring is provided.

[0010] As a preferred technical solution, the yarn bobbin mounting roller is a one-piece molded plastic part.

[0011] This application also provides a yarn rewinder, which includes the aforementioned yarn rewinding component. This application also provides a yarn doubling machine, which includes the aforementioned yarn rewinder.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: The yarn bobbin mounting roller and the rewinding bobbin are interference-fitted via O-rings. If relative rotation occurs between the yarn bobbin mounting roller and the rewinding bobbin, and between the O-ring and the yarn bobbin mounting roller, significant frictional forces will be generated, hindering relative rotation between them. Therefore, this application ensures a secure installation of the rewinding bobbin and the yarn rewinding component, preventing relative rotation and allowing the yarn to be evenly wound on the rewinding bobbin, thus avoiding interference with subsequent textile processes.

[0013] When the rewinding bobbin is removed from the yarn bobbin mounting roller, since the diameter of the rewinding bobbin mounting part is slightly smaller than the inner diameter of the rewinding bobbin, only the O-ring and the rewinding bobbin are in contact on the yarn rewinding component. At this time, the O-ring rotates within the O-ring mounting groove and moves along the width direction of the O-ring mounting groove. Therefore, there is rolling friction between the O-ring and the rewinding bobbin, and the frictional force is very small. Therefore, this application can easily remove the rewinding bobbin from the yarn rewinding component, and similarly, it can also easily install the rewinding bobbin onto the yarn rewinding component.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, this application provides a yarn rewinding component 101, which includes a yarn bobbin mounting roller 11 and an O-ring 12. The yarn rewinding component 101 is used to fix and mount a rewinding bobbin 301. In this application, the rewinding bobbin 301 is made of Lycra paper tubes or the like.

[0020] The yarn bobbin mounting roller 11 has a yarn bobbin mounting portion 111 at each opposite end along the axial direction. The inner diameter of the yarn bobbin mounting portion 111 is equal to the outer diameter of the yarn bobbin 201 of the yarn-drawing machine, so that the yarn bobbin mounting roller 11 can be fixedly mounted on the yarn bobbin 201 of the yarn-drawing machine. The yarn bobbin 201 is a key component of the yarn-drawing machine. It is a hollow cylinder used to accommodate and transport multiple parallel yarns. After the yarn bobbin mounting roller 11 is fixedly mounted on the yarn bobbin 201 of the yarn-drawing machine, the yarn bobbin mounting roller 11 can rotate with the yarn bobbin 201. It should be noted that limiting components such as limiting pins 112 can be provided to limit the relative rotation of the yarn bobbin 201 and the yarn bobbin mounting roller 11.

[0021] The yarn bobbin mounting roller 11 has a rewinding bobbin mounting part 113 in the middle. The diameter of the rewinding bobbin mounting part 113 is slightly smaller than the inner diameter of the rewinding bobbin 301, so that the rewinding bobbin mounting part 113 and the rewinding bobbin 301 do not come into close contact during the installation or disassembly process, thereby making it easy to install or disassemble the rewinding bobbin 301.

[0022] The rewinding drum mounting part 113 is provided with an annular O-ring mounting groove 114. An O-ring 12 is installed within the O-ring mounting groove 114. The outer diameter of the O-ring 12 is larger than the inner diameter of the rewinding drum 301, and the inner diameter of the O-ring 12 is less than or equal to the diameter of the bottom of the O-ring mounting groove 114. Because the O-ring 12 can undergo elastic deformation, it can pass through the rewinding drum mounting part 113, whose diameter is larger than that of the O-ring 12, and be installed into the O-ring mounting groove 114.

[0023] The width of the O-ring mounting groove 114 is greater than the width of the O-ring 12, so that the O-ring 12 can be rotated in the O-ring mounting groove 114 and moved along the width direction of the O-ring mounting groove 114 when the rewinding spool 301 is loaded and unloaded.

[0024] With the above arrangement, the yarn bobbin mounting roller 11 and the rewinding bobbin 301 are interference-fitted through the O-ring 12. If relative rotation occurs between the yarn bobbin mounting roller 11 and the rewinding bobbin 301, significant friction will be generated between the O-ring 12 and the rewinding bobbin 301, and between the O-ring 12 and the yarn bobbin mounting roller 11, thus hindering relative rotation between them. Therefore, this application ensures that the rewinding bobbin 301 and the yarn rewinding component 101 are securely installed and unlikely to rotate relative to each other, allowing the yarn to be evenly wound on the rewinding bobbin 301, thereby avoiding interference with subsequent weaving processes.

[0025] When the rewinding spool is removed from the yarn spool mounting roller 11, since the diameter of the rewinding spool mounting part 113 is slightly smaller than the inner diameter of the rewinding spool 301, only the O-ring 12 and the rewinding spool 301 are in contact on the yarn rewinding component 101. At this time, the O-ring 12 flips within the O-ring mounting groove 114 and moves along the width direction of the O-ring mounting groove 114. Therefore, there is rolling friction between the O-ring 12 and the rewinding spool 301, and the frictional force is very small. Therefore, this application can easily remove the rewinding spool 301 from the yarn rewinding component 101, and similarly, it can also easily mount the rewinding spool 301 onto the yarn rewinding component 101.

[0026] As one implementation, the yarn bobbin mounting roller 11 is also provided with a limiting step portion 115, which is located at one end of the rewind bobbin mounting portion 113. The outer diameter of the limiting step portion 115 is larger than the inner diameter of the rewind bobbin 301. When the rewind bobbin 301 is mounted on the yarn bobbin mounting roller 11, one end of the rewind bobbin 301 abuts against the limiting step portion 115, which is used for the mounting and positioning of the rewind bobbin 301.

[0027] In one implementation, the yarn bobbin mounting portion 113 has a guide portion 116 at the end away from the limiting step portion 115. The diameter of the guide portion 116 decreases from the middle of the yarn bobbin mounting portion 113 to the end of the yarn bobbin mounting portion 113. When the yarn bobbin 301 is mounted onto the yarn bobbin mounting roller 11, the guide portion 116 guides the yarn bobbin 301 to facilitate its installation.

[0028] As one implementation, the width of the O-ring mounting groove 114 is greater than or equal to one-third of the width of the thread-reversing spool mounting portion 113, so as to avoid the width of the O-ring mounting groove 114 being too small, thereby preventing the thread-reversing spool 301 from failing to be fully installed on or completely removed from the thread-reversing spool mounting portion 113 when the O-ring 12 rolls to the two sides of the O-ring mounting groove 114; and the width of the O-ring mounting groove 114 is less than or equal to two-thirds of the width of the thread-reversing spool mounting portion 113, so as to avoid the width of the O-ring mounting groove 114 being too large, thereby preventing the thread-reversing spool 301 from axially moving relative to the thread-reversing spool mounting portion 113.

[0029] As one implementation method, the yarn bobbin mounting roller 11 is a one-piece molded plastic part to facilitate the production and manufacturing of the yarn bobbin mounting roller 11.

[0030] like Figure 3 As shown, in another embodiment, multiple O-rings 12 are provided to improve the firmness of the rewinding bobbin 301 on the yarn rewinding component 101.

[0031] This application also provides a yarn rewinder, which includes the yarn rewinding component 101 described above. Therefore, the yarn rewinder also has the beneficial effect of making the rewinding spool 301 and the yarn rewinding component 101 firmly installed and not prone to relative rotation, and making it easy to load and unload the rewinding spool 301.

[0032] This application also provides a yarn doubling machine, which includes the above-mentioned yarn rewinder. Therefore, the yarn doubling machine also has the beneficial effect of making the rewinder 301 and the yarn rewinding component 101 firmly installed and not prone to relative rotation, and making it easy to load and unload the rewinder 301.
