Description

Technical Field

[0001] This invention relates to the field of false twist texturing machine technology, specifically a high-efficiency false twist texturing machine without a channel. Background Technology

[0002] False-twist textured machines are key equipment in the processing of synthetic fibers, imparting bulk and elasticity to the yarn through processes such as heating, twisting, and setting. Traditional false-twist textured machines typically have a long tunnel structure between the exit roller and the take-up device for guiding and cooling the yarn. However, the presence of this tunnel results in a large overall longitudinal length of the equipment, occupying a significant amount of production space, limiting the number of machines that can be arranged per unit area, and affecting production efficiency. Furthermore, the yarn travels for extended periods within the tunnel and continuously rubs against the air and the tunnel walls, easily causing surface damage, fuzzing, and even yarn breakage. This is especially problematic under high-speed, high-tension processing conditions, significantly impacting the stability of yarn quality. Another significant drawback of the tunnel structure in traditional false-twist textured machines is that after the yarn bobbins have finished spinning, the physical obstruction of the tunnel prevents conventional bobbin-dropping trolleys from entering, necessitating manual removal of the dropped bobbins. This process not only increases labor intensity but also prolongs operation time.

[0003] Therefore, there is an urgent need to develop a high-efficiency false twisting deformation machine without a channel to solve the problems in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency false-twist texturing machine without a channel. By vertically integrating the take-up roller above the exit roller, it achieves the technical effects of eliminating the traditional channel, shortening the longitudinal length of the equipment, reducing yarn friction damage, and facilitating the unwinding operation. Moreover, it has a simple structure and is easy to use, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency false-twist texturing machine without a channel, comprising: A main frame, on which an inlet roller is fixedly connected; A first heating box is fixedly connected to the main frame. The inlet of the first heating box is connected to the inlet roller. The outlet of the first heating box is provided with a false twist device, which is fixedly connected to the main frame. The second heating box is located below the false twisting device and is fixedly connected to the main frame. The outlet of the second heating box is provided with a wire exit roller, which is fixedly connected to the main frame. A gathering roller is also fixedly connected to the main frame, and the gathering roller is located above the output roller.

[0006] By adopting the above technical solution, the take-up roller is positioned directly above the exit roller, eliminating the traditional long passageway located on the side of the machine. This directly shortens the overall longitudinal length of the equipment. At the same time, the path of the yarn from twisting and setting to winding is greatly shortened, reducing the time the yarn travels and rubs in the air, thereby reducing the probability of surface damage to the yarn.

[0007] As a further aspect of the present invention: a first wire guide is fixedly connected to the first heating box, the first wire guide is disposed between the inlet of the first heating box and the inlet roller; the first wire guide includes: a connecting plate and a wire guide wheel, the connecting plate is fixedly connected to the first heating box, and the wire guide wheel is rotatably connected to the connecting plate.

[0008] By adopting the above technical solution, the first wire guide is used to precisely guide the wire from the inlet roller into the first heating chamber. The rotation of the wire guide wheel reduces the frictional resistance when the wire enters, ensuring that the wire enters the heating chamber at the correct position and angle, providing a foundation for subsequent stable processing and avoiding additional friction or uneven tension caused by inaccurate guidance.

[0009] As a further aspect of the present invention: a second wire guide is fixedly connected to the main frame, the second wire guide having the same structure as the first wire guide, and the second wire guide is located at the outlet of the first heating box.

[0010] By adopting the above technical solution, the second guide wire is used to receive and guide the high-temperature wire that has just come out of the first heating box. Its rotating guide wheel structure can smoothly change the direction of the wire, reduce scratching of the heated wire, ensure that the wire is stably fed to the subsequent cooling and false twisting processes, and prevent the wire quality from deteriorating due to improper guidance.

[0011] As a further aspect of the present invention: the main frame is also provided with a cooling guide plate, the cooling guide plate is fixedly connected to the main frame, and the cooling guide plate is disposed between the second conductor and the false twist device.

[0012] By adopting the above technical solution, the cooling guide plate is used to forcibly cool the heated yarn. The yarn exchanges heat with the surface of the guide plate, rapidly reducing its temperature to a suitable range for false twisting. This replaces part of the cooling function of the traditional channel, resulting in a more compact structure, creating conditions for stable false twisting, and shortening the overall process path.

[0013] As a further aspect of the present invention, the cooling guide plate is V-shaped.

[0014] By adopting the above technical solution, the V-shaped structure increases the contact area between the yarn and the guide plate and makes the contact more stable, thereby improving cooling efficiency. At the same time, the V-shaped groove can naturally position the yarn, preventing it from shifting laterally during cooling, ensuring that the yarn accurately enters the false twisting device, and reducing friction and processing instability caused by deviation.

[0015] As a further embodiment of the present invention: the false twist device includes: a base, a thread clamp, and a false twist disc. The base is fixedly connected to the main frame, the thread clamp is slidably connected to the base, and the false twist disc is rotatably connected to the base. The thread clamp is used to clamp the thread into the false twist disc.

[0016] By adopting the above technical solution, this structure achieves stable false twisting of the yarn. The base provides stable support, and the sliding yarn clamp allows the operator to quickly guide the yarn into the false twisting disc, while the rotating disc twists the yarn. The overall structure is compact, easy to operate, and the twisting process is stable, which helps to reduce yarn breakage or damage during the twisting process.

[0017] As a further aspect of the present invention: a guide roller is provided between the false twisting device and the second heating box, and the guide roller is fixedly connected to the main frame.

[0018] By adopting the above technical solution, the guide roller is used to support and guide the twisted yarn from the false twisting device, and feeds it into the second heating chamber for heat setting with a set tension. It plays a role in transitioning and stabilizing the tension, preventing the yarn from becoming loose or excessively rubbed before entering the second heating chamber, thus ensuring the smooth progress of the setting process.

[0019] As a further embodiment of the present invention: the feed roller includes: a pressure arm, a fixed plate, a main roller and an auxiliary roller; the fixed plate is fixedly connected to the main frame, the pressure arm is rotatably connected to the fixed plate, the main roller is rotatably connected to the fixed plate, and the auxiliary roller is rotatably connected to the pressure arm.

[0020] By adopting the above technical solution, this structure uses a rotating pressure arm to press the auxiliary roller against the main roller, forming a clamping jaw to hold the yarn. The main roller actively rotates to feed the yarn, and the auxiliary roller rotates accordingly. This structure provides stable and adjustable yarn feeding tension, preventing yarn slippage or tension fluctuations from the beginning of processing, creating conditions for the stability of subsequent processes, and reducing yarn damage caused by tension issues.

[0021] As a further aspect of the present invention: the structure of the lead roller and the outlet roller are the same as the structure of the inlet roller.

[0022] By adopting the above technical solution, the same roller structure is used in all key nodes of the yarn feeding process (inletting and exiting after shaping). This ensures the uniformity and controllability of the yarn tension throughout the entire process, reduces the risk of friction, vibration, or yarn breakage caused by poor transmission between rollers with different structures, and improves processing stability and yarn quality.

[0023] As a further aspect of the present invention: multiple gathering rollers can be vertically arranged and fixedly connected to the main frame, and multiple gathering rollers can be driven by multiple drive motors, or multiple gathering rollers can be driven by a single drive motor and transmission assembly.

[0024] By adopting the above technical solution, multiple take-up rollers are longitudinally integrated above the main frame, making full use of the upper space of the equipment. This vertical arrangement significantly reduces the horizontal footprint of the equipment, further achieving the goal of a compact overall structure and shortened longitudinal length. Two drive methods provide flexibility, both capable of efficiently completing the winding operation.

[0025] Compared with the prior art, the beneficial effects of the present invention are: by vertically integrating the gathering roller above the exit roller, the technical effects of eliminating the traditional passageway, shortening the longitudinal length of the equipment, reducing yarn friction damage, and facilitating the unloading operation are achieved.

[0026] Other features and advantages of the present invention will be disclosed in detail in the following detailed description and accompanying drawings. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: This embodiment provides a channelless, high-efficiency false-twist texturing machine for false-twist texturing of synthetic fibers. (Reference) Figures 1 to 2 The false twisting texturer includes a main frame 1, and an inlet roller 2, a first heating box 3, a false twisting device 5, a second heating box 7, an outlet roller 8, and a take-up roller 9 arranged sequentially on the main frame 1.

[0031] The processing path of the yarn is as follows: the yarn is first drawn into the first heating box 3 by the infeed roller 2 for heating. After cooling, the heated yarn enters the false twisting device 5 for twisting. The twisted yarn is then heat-set in the second heating box 7 and finally drawn out by the output roller 8. The key improvement is that the take-up roller 9 is directly fixed on the main frame 1 and located directly above the output roller 8. After the yarn is output from the output roller 8, it is guided vertically or diagonally upwards directly to the take-up roller 9 for winding and collection.

[0032] This embodiment completely eliminates the long passageway connecting the exit roller and the take-up device in traditional false twisting machines by integrating the take-up roller 9 above the exit roller 8. This change directly shortens the overall longitudinal length of the machine. At the same time, the path of the yarn from heat setting to winding is drastically shortened, significantly reducing the time and distance the yarn travels suspended in the air and rubs against the equipment components, thereby reducing the probability of yarn surface damage and breakage.

[0033] Example 2: refer to Figure 1 , 3Based on Embodiment 1, a first guide wire 31 is fixedly installed at the inlet of the first heating box 3. The first guide wire 31 consists of a connecting plate 311 and a guide wheel 312. The connecting plate 311 is fixed to the first heating box 3, and the guide wheel 312 is rotatably connected to the connecting plate 311. At the outlet of the first heating box 3, a second guide wire 10 with the same structure is installed on the main frame 1.

[0034] A V-shaped cooling guide plate 4 is fixedly installed on the main frame 1 between the second guide wire 10 and the false twisting device 5.

[0035] This embodiment utilizes the rotating guide wheel structure of the first guide wire 31 and the second guide wire 10 to ensure that the yarn enters and leaves the first heating box 3 smoothly and with low friction, preventing yarn scratching. The V-shaped cooling guide plate 4 increases the contact area of ​​the yarn, achieving rapid and uniform cooling of the heated yarn, and the V-shaped structure also positions the yarn to prevent deviation. These structures collectively replace some of the guiding and cooling functions of the traditional long channel for the yarn, achieving a compact layout while providing the necessary conditions for stable false twist.

[0036] Example 3: refer to Figures 4 to 6 This embodiment provides a detailed description of several key functional components of the false twisting texturing machine.

[0037] The feed roller 2 includes a fixed plate 22, a main roller 23, a pressure arm 21, and an auxiliary roller 24. The fixed plate 22 is fixed to the main frame 1, and the main roller 23 is rotatably mounted on the fixed plate 22. One end of the pressure arm 21 is hinged to the fixed plate 22, and the auxiliary roller 24 is rotatably mounted on the other end of the pressure arm 21. By pressing down the pressure arm 21, the auxiliary roller 24 can be pressed against the main roller 23 to form a wire feeding jaw. The lead roller 6 and the output roller 8 adopt the same structure as the feed roller 2.

[0038] The false twist device 5 includes a base 51, a false twist disc 53, and a thread clamp 52. The base 51 is fixed to the main frame 1, the false twist disc 53 is rotatably mounted on the base 51, and the thread clamp 52 is slidably mounted on the base 51 for clamping the thread into the twist groove of the false twist disc 53.

[0039] In this embodiment, the infeed roller 2, the guide roller 6, and the outfeed roller 8 adopt a unified pressure roller structure, ensuring the uniformity and controllability of tension transmission throughout the entire processing path, and reducing thread quality problems caused by tension fluctuations at the system level. The false twisting device 5 has a compact structure, and the sliding design of the wire clamp 52 facilitates the rapid introduction of the thread, improving operating efficiency.

[0040] Example 4: refer to Figure 2This embodiment provides a detailed description of the layout of the gather rollers 9. Multiple gather rollers 9 can be fixedly installed on the upper part of the main frame 1 in a vertically arranged manner. Their driving method can be either driven separately by multiple drive motors, or a single drive motor can synchronously drive multiple gather rollers 9 through a transmission assembly.

[0041] This embodiment vertically integrates the gathering function unit above the main frame, rather than arranging it horizontally on one side of the machine as is traditionally done. This vertical arrangement further reduces the horizontal footprint of the equipment, making the false-twist texturing machine of this invention more compact. More machines can be arranged side-by-side within the same factory space, significantly improving space utilization and productivity per unit area. Comparative Example: Comparison between a conventional false-twist texturing machine and the present invention refer to Figure 1 , 7 Traditional false-twist texturing machines typically include a long tunnel. This tunnel connects the exit roller and the take-up frame, and is used to guide and cool the yarn exiting the second heating chamber.

[0042] The problem with traditional structures is that the machine body is long: the long passageway significantly increases the overall longitudinal dimension of the equipment, occupies more production space, and limits the number of machines that can be placed per unit area.

[0043] High yarn damage rate: When yarn travels at high speed and over long distances in long tunnels, it is subject to continuous friction with the air and the tunnel walls, which can easily cause the yarn surface to become fuzzy, produce fuzz, or even break, affecting the quality of finished yarn and production efficiency.

[0044] The present invention provides a high-efficiency false-twist texturing machine without a passageway. By eliminating the long passageway and placing the take-up roller 9 directly above the exit roller 8, a compact vertical yarn path is formed. Its advantages are as follows: Shortened body: The passageway structure was directly eliminated, significantly shortening the overall length of the machine and making it easier to increase the number of equipment units in a limited space.

[0045] Reduced friction: The path of the yarn from the end of setting to winding is extremely short, which greatly reduces the friction links and exposure time, effectively reducing yarn damage and breakage caused by friction, and improving product quality and processing stability.

[0046] Efficient layout: The vertically integrated design optimizes space utilization, making the equipment structure more rational and the process more seamless.

[0047] Compared with current mainstream models, this invention further demonstrates significant comprehensive advantages: compared with the 1000-type texturing machine, this equipment performs exceptionally well in terms of energy consumption, with significant energy-saving effects, which helps enterprises reduce costs and increase efficiency; compared with the 900-type texturing machine, it has higher production capacity and more stable operation per unit time, thereby significantly reducing the labor intensity of operators; at the same time, the overall structural design is more compact, and the equipment height is further reduced compared with similar products, making the starting, wire hanging, daily inspection and unloading operations more convenient and labor-saving, improving human-machine collaboration efficiency and operating comfort.

[0048] This invention provides a high-efficiency false-twist texturing machine without a channel. By vertically integrating the take-up roller above the exit roller, it achieves the technical effects of eliminating the traditional channel, shortening the longitudinal length of the equipment, reducing yarn friction damage, and facilitating the drop-off operation, resulting in high reliability.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
