[0003] Currently, when placing the silk thread into the friction roller for rolling, a guide bracket is usually used to press the unformed silk thread between the friction rollers. In this way, the silk thread needs to be aligned with the guide bracket, which makes it difficult to process the silk thread and makes it impossible to quickly position the silk thread between the friction rollers.

The guide bracket is no longer used to press the silk thread into between the friction rollers. Instead, a driving motor is used to drive at least two fixed columns to rotate. The rotation of the two fixed columns will drive the rollers arranged thereon to rotate. At this time, the raw silk material is arranged on one side of the rotating roller, and the rotating roller is used to bring the raw silk material to the first axis. Then, at the first axis, the raw silk material passes through the cross-arranged rollers in turn, and the multiple rollers roll the raw silk material in turn to achieve false twisting and bending deformation of the raw silk material, thereby improving the elasticity of the raw silk material.

[0022] Through the friction roller assembly provided by the utility model, there is no need to use additional auxiliary tools to press the raw silk material between the roller discs.

[0038] The texturing machine is a kind of textile machine that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium elasticity and low elasticity through false twisting. When processing the silk thread through the texturing machine, the friction roller in the texturing machine is mainly used to roll the silk thread, so that the silk thread is falsely twisted or curled, so that the silk thread has elasticity.

[0039] Currently, when placing the silk thread into the friction roller for rolling, a guide bracket is usually used to press the unformed silk thread between the friction rollers. In this way, the silk thread needs to be aligned with the guide bracket, which makes it difficult to process the silk thread and makes it impossible to quickly position the silk thread between the friction rollers.

[0040] In order to solve the technical problem that the existing wire processing method has certain processing difficulties and cannot quickly realize the positioning of the wire between the friction rollers, refer to Figures 1 to 3In one embodiment of the utility model, a friction roller assembly for nylon yarn processing is provided, which is used for stretching raw yarn material to make the raw yarn material elastic. The friction roller assembly includes a fixed column 100, a roller disc 200 and a driving motor 300. The fixed column 100 includes at least three, and the three fixed columns 100 are arranged at intervals around the first axis (more preferably, the three fixed columns 100 can be evenly spaced around the first axis). The roller disc 200 is arranged on the fixed column 100, and the roller discs 200 on two adjacent fixed columns 100 are arranged crosswise. The driving motor 300 is connected to the fixed column 100 to drive at least two fixed columns 100 to rotate. Among them, the roller disc 200 can rotate with the fixed column 100 to pull the raw yarn material to the first axis.

[0041] Specifically, in order to solve the above-mentioned problems, in the present embodiment, the friction roller used for rolling the silk thread in the texturizing machine is structurally improved, and the guide bracket originally arranged in the friction roller assembly is cancelled. The guide bracket is no longer used to press the silk thread into between the friction rollers. Instead, a driving motor 300 is used to drive at least two fixed columns 100 to rotate. When the two fixed columns 100 rotate, the roller 200 arranged thereon will also be driven to rotate. At this time, the raw silk material is arranged on one side of the rotating roller 200, and the rotating roller 200 is used to bring the raw silk material to the first axis. Then, at the first axis, the raw silk material passes through the cross-arranged rollers 200 in turn, and the multiple rollers 200 roll the raw silk material in turn to achieve false twisting and bending deformation of the raw silk material, thereby improving the elasticity of the raw silk material.

[0042] Through the friction roller assembly provided in this embodiment, there is no need to use additional auxiliary tools to press the raw silk material into the roller discs 200. The raw silk material can be actively brought into the roller discs 200 by simply using the rotating roller discs 200, so as to achieve false twisting and curling deformation of the raw silk material between the roller discs 200, so that the raw silk material can be processed into elastic yarn. The friction roller assembly provided in this embodiment has a simple structure, is convenient for quickly realizing the positioning of the raw silk material between the roller discs 200, is conducive to reducing the processing difficulty of the raw silk material, improving the processing accuracy of the raw silk material, improving the processing efficiency of the raw silk material, and reducing the processing cost of the raw silk material.

[0043] Further, after the raw silk material is brought to the first axis by the rotating roller 200, the roller 200 can continue to rotate so that the raw silk material is deformed by false twisting between the rotating rollers 200, or the roller 200 can also stop rotating so that the raw silk material is deformed by false twisting between the stationary rollers 200. Compared with the method in which the raw silk material is deformed by false twisting between the stationary rollers 200, the method in which the raw silk material is deformed by false twisting between the rotating rollers 200 is more conducive to the roller 200 to perform rapid rolling processing on the raw silk material, thereby helping to improve the processing efficiency and effect of the raw silk material. It is worth noting that when the raw silk material is deformed by false twisting between the rotating rollers 200, each roller 200 needs to rotate at the same speed to prevent the speed difference between the rollers 200 from deviating the raw silk material, causing the raw silk material to deviate from the first axis and affect the processing progress of the raw silk material.

[0044] It can be understood that the friction roller assembly for nylon yarn processing provided in this embodiment can also be used for other yarn texturizing treatments.

[0045] In some embodiments, reference Figures 1 to 3 Each fixed column 100 is provided with a plurality of rollers 200. For example, three rollers 200 may be provided on each fixed column 100. Along the length direction X of the fixed column 100, the rollers 200 on each fixed column 100 are arranged in a stepped manner, and along the direction of rolling the raw silk material, the diameter of the rollers 200 on each fixed column 100 gradually increases.

[0046] Specifically, in order to further improve the rolling effect of the raw silk material between the rollers 200, in the present embodiment, the structure of the multiple rollers 200 on each fixed column 100 is improved, so that the diameters of the multiple rollers 200 on each fixed column 100 are different, and the diameter of the rollers 200 on each fixed column 100 gradually increases along the direction of rolling and moving of the raw silk material. With such a structure, since the diameter of the roller 200 is one of the important factors affecting the roller pressure of the roller 200 on the raw silk material, usually, the larger the diameter of the roller 200, the greater the roller pressure on the raw silk material. When the raw silk material just enters between the rollers 200 for rolling, a roller 200 with a smaller diameter is first used to apply a smaller roller pressure to the raw silk material to prevent the roller 200 from applying too much roller pressure to the raw silk material at the beginning and directly causing the raw silk material to break, affecting the subsequent processing of the raw silk material. When the raw silk material begins to curl and deform, a roller 200 with a larger diameter is used to apply a larger roller pressure to the raw silk material, thereby improving the curling deformation effect of the raw silk material and making the raw silk material more elastic.

[0047] It should be noted that, in order to ensure the coordination and rationality of the overall structure of the friction roller assembly and to prevent a large gap from being generated between the roller disc 200 with a smaller diameter and the fixed column 100, the diameters of the roller discs 200 on each fixed column 100 will not differ too much. For example, if the diameter of the smallest roller disc 200 is 10 cm, the diameter of the largest roller disc 200 may be 10.5 cm. The diameter difference between the roller discs 200 may be adaptively adjusted according to processing requirements.

[0048] In some embodiments, reference Figure 2 , along the radial direction of the roller disc 200 , the distance L between the outer peripheral wall of the roller disc 200 and the adjacent fixing column 100 satisfies: 1 cm ≤ L ≤ 3 cm. Exemplarily, for example, the value of L can be 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, and so on.

[0049] Specifically, in order to further improve the rolling effect of the raw silk material between the rollers 200, in this embodiment, the spacing distance between the rollers 200 and the adjacent fixed columns 100 is limited, so that the spacing distance between the outer peripheral wall of each roller 200 and the adjacent fixed column 100 is between 1 cm and 3 cm (including the end value). With such a structure, on the one hand, it can effectively prevent the spacing distance between the outer peripheral wall of each roller 200 and the adjacent fixed column 100 from being too small. For example, the spacing distance between the outer peripheral wall of the roller 200 and the adjacent fixed column 100 is set to 0.3 cm, 0.5 cm, 0.7 cm, etc., which causes the raw silk material to be tightly squeezed between the roller 200 and the fixed column 100 during the movement, thereby making it difficult for the raw silk material to be rolled and moved between the rollers 200, so that the raw silk material is easily worn or even broken during the movement between the rollers 200. On the other hand, it can also effectively prevent the outer wall of each roller 200 and the adjacent fixed column 100 from being too large. For example, the outer wall of the roller 200 and the adjacent fixed column 100 are set to 3.5 cm, 4 cm, 4.5 cm, etc., which may result in the raw silk material being unable to be in close contact with the outer wall of the roller 200, so that the roller 200 cannot provide a sufficiently large roller pressure for the raw silk material (the sufficiently large roller pressure mentioned here refers to the roller pressure corresponding to the size of the false twist curling deformation of the raw silk material), which will affect the elastic processing effect of the raw silk material, resulting in the raw silk material after being processed by the friction roller assembly failing to meet the production requirements.

[0050] By making the distance L between the outer wall of the roller 200 and the adjacent fixed column 100 satisfy the above-mentioned design (1cm≤L≤3cm), the distance L between the outer wall of the roller 200 and the adjacent fixed column 100 can be kept moderate, which can not only ensure the compact arrangement of the rollers 200, but also facilitate the movement of the raw silk material between the rollers 200, so that the rollers 200 provide appropriate roller pressure on the raw silk material, improve the stretching effect of the raw silk material between the rollers 200, and make the raw silk material more elastic after being stretched and curled.

[0051] In some embodiments, a driving unit (not shown) is disposed at the ends of the three fixing columns 100 , and the driving unit is configured to drive the fixing columns 100 to move toward or away from the first axis.

[0052] Specifically, in order to improve the versatility of the friction roller assembly and meet the processing requirements for raw silk materials of different thicknesses and different numbers (for example, multiple raw silk materials can be placed between the rollers 200 and the rollers 200 can be used to roll the multiple raw silk materials at the same time), in this embodiment, the driving unit can drive the fixed column 100 to move in a direction close to or away from the first axis, thereby adjusting the distance between the rollers 200 and the fixed column 100, so that the distance between each roller 200 and the adjacent fixed column 100 meets the design in the above embodiment (1cm≤L≤3cm), thereby ensuring the processing effect of the raw silk material between the rollers 200 and meeting the elasticity requirements of the processed raw silk material.

[0053] Furthermore, when the roller 200 is used to process thicker raw silk materials or a larger number of raw silk materials, the driving unit can be used to drive some or all of the fixed columns 100 to move in a direction away from the first axis, so that the distance between the roller 200 and the fixed columns 100 increases. By way of example, for example, the increased distance can be 2.5 cm, 2.8 cm, 3 cm, etc., thereby ensuring that the roller 200 can provide the raw silk material with a suitable amount of roller pressure while ensuring that the raw silk material can pass smoothly between the rollers 200. Similarly, when the roller 200 is used to process thinner raw silk materials or a smaller number of raw silk materials, the driving unit can be used to drive some or all of the fixed columns 100 to move in a direction close to the first axis, so that the distance between the roller 200 and the fixed columns 100 is reduced. For example, the reduced distance can be 1 cm, 1.3 cm, 1.5 cm, etc., thereby ensuring that the roller 200 can provide a suitable amount of roller pressure for the raw silk material while ensuring that the raw silk material can pass smoothly between the rollers 200.

[0054] In some embodiments, the driving part can be a screw structure, which can drive the fixing column 100 to move linearly toward or away from the first axis. It should be noted that the screw structure is a common structural device in the field, so the specific structure and working principle of the screw structure will not be described in detail.

[0055] In some embodiments, reference Figure 1 to Figure 2 The friction roller assembly further includes a wire sensor 400, which is disposed at the first axis and is used to sense the raw wire at the first axis. The wire sensor 400 and the drive motor 300 are both connected to the controller, and the wire sensor 400 transmits the sensing signal detected at the first axis to the controller, and the controller controls the drive motor 300 to operate according to the sensing signal.

[0056] Specifically, in order to improve the processing accuracy of the raw silk material, the raw silk material will be rolled only after it moves to the first axis. In this embodiment, a silk material sensor 400 is provided at the first axis. The silk material sensor 400 can be used to detect whether the raw silk material has moved into place. Only when the raw silk material has moved into place (moving into place here means that the raw silk material has moved to the first axis), the friction roller assembly will be controlled to proceed to the next processing step.

[0057] Further, referring to the above embodiment, when the raw silk material is false-twisted and curled by the rotating roller 200, after the silk material sensor 400 detects that the raw silk material moves to the first axis, that is, after the raw silk material moves to the right position, the controller will control the drive motor 300 to rotate at a higher speed (the higher speed mentioned here means that the speed of the driving roller 200 when formally rolling the raw silk material is greater than the speed when the driving roller 200 initially brings the raw silk material into the first axis). At this time, driven by the fixed column 100, the roller 200 will rotate at a higher speed, thereby realizing the rapid rolling processing of the raw silk material by the roller 200. When the silk material sensor 400 does not detect that the raw silk material moves to the first axis, that is, when the raw silk material does not move to the right position, the controller will continue to control the drive motor 300 to rotate at the initial speed.

[0058] When the raw silk material is false-twisted and curled by the stationary roller 200, after the silk material sensor 400 detects that the raw silk material has moved to the first axis, that is, the raw silk material has moved to the right position, the controller will control the drive motor 300 to stop rotating. At this time, driven by the fixed column 100, the roller 200 will stop rotating, so that the raw silk material enters the rolling process. When the silk material sensor 400 does not detect that the raw silk material has moved to the first axis, that is, the raw silk material has not moved to the right position, the controller will continue to control the drive motor 300 to rotate at the initial speed.

[0059] In some embodiments, a rubber layer (not shown in the figure) is disposed on the outer peripheral wall of the roller disc 200 along the radial direction of the roller disc 200 .

[0060] Specifically, in order to ensure that the rolling process of the raw silk material proceeds smoothly, in this embodiment, a rubber layer is provided on the outer peripheral wall of the roller 200. The rubber layer can effectively prevent the raw silk material from adhering to the outer peripheral wall of the roller 200, thereby ensuring that the raw silk material can continue to pass through between the rollers 200, thereby realizing continuous rolling of the raw silk material.

[0061] In some embodiments, the rubber layer can be sleeved on the outer wall of the roller 200 in the form of a rubber sleeve. With such a structure, it is convenient to install, disassemble and replace the rubber layer.

[0062] In some embodiments, the roller 200 is a ceramic structure. Such a structure is conducive to improving the hardness of the roller 200, so that the roller 200 is not easily deformed under tension and pressure, thereby ensuring that the roller 200 can provide a stable roller pressure for the raw silk material. In addition, such a structure is conducive to improving the service life of the roller 200, so that the roller 200 is not easy to rust and age, thereby saving the manufacturing cost of the roller 200.

[0063] In some embodiments, the fixed column 100 and the roller 200 are connected by threads. For example, the fixed column 100 may be provided with external threads, and the roller 200 may be provided with internal threads, and the external threads and the internal threads cooperate with each other to stably connect the roller 200 to the fixed column 100. The roller 200 and the fixed column 100 are connected by threads, which facilitates the installation of the roller 200 on the fixed column 100, and the removal and replacement of the roller 200 from the fixed column 100.

[0064] Specifically, in this embodiment, the fixing column 100 may be a stainless steel metal structure, and the roller 200 may be a ceramic structure.

[0065] In some embodiments, the fixed column 100 and the roller disc 200 are an integrally formed structure. Exemplarily, for example, the fixed column 100 and the roller disc 200 can be made of the same material, such as ceramic, and the fixed column 100 and the roller disc 200 are integrally formed by injection molding. The roller disc 200 and the fixed column 100 are in the form of an integrally formed structure, which is convenient for processing and molding the roller disc 200 and the fixed column 100, and is conducive to reducing the difficulty of assembling the roller disc 200 and the fixed column 100.

[0066] Correspondingly, another embodiment of the utility model further provides a texturizing machine, which includes the friction roller assembly for nylon yarn processing in any of the above embodiments.

[0067] Specifically, in this embodiment, the texturizing machine using the friction roller assembly for nylon yarn processing is advantageous for roller-pressing the raw yarn material, so that the raw yarn material can be easily processed into elastic yarn.

[0068] In some embodiments, the texturizing machine may further include a feeding mechanism, a heating mechanism, a cooling mechanism, a shaping structure, an oiling mechanism, a winding mechanism, and the like.

[0069] The process of processing raw silk material using a texturing machine is as follows: the raw silk material is placed on the feeding mechanism, and the raw silk material is transferred to the heating mechanism through the feeding mechanism for heating treatment. The raw silk material is heated by a heat source to soften the silk thread, and then the raw silk material is quickly transferred to the cooling mechanism, and the raw silk material after heating is cooled, so that the raw silk material quickly expands and contracts with heat and cold, and the curling and bulkiness of the raw silk material are improved. Then the cooled raw silk material is transferred to the friction roller assembly for false twist curling treatment, and the raw silk material is shaped by the shaping mechanism. Finally, the surface of the raw silk material is oiled by the oiling mechanism to improve the fiber bundling, increase the fiber smoothness, and improve the fiber antistatic property. Finally, the raw silk material is wound up by the winding mechanism, and the texturing process of the raw silk material is completed.

[0070] Thanks to the improvement of the friction roller assembly for nylon yarn processing mentioned above, the texturizing machine of this embodiment has the same technical effect as the friction roller assembly for nylon yarn processing mentioned above, which will not be described in detail here.

[0071] It should be noted that other contents of the friction roller assembly and texturizing machine for nylon yarn processing disclosed in the present invention can be referred to the prior art and will not be described in detail here.

[0072] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
