Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a silk heating mechanism and a false twist texturer. Background Technology

[0002] In the field of chemical fiber textiles, false twist texturers are key equipment for processing and shaping filament products (such as polyester and nylon filaments). One of their core functions is to improve the physical properties of the filament through heat treatment, such as enhancing its elasticity, strength, and dyeing uniformity, thereby ensuring the quality of the final textile products. Currently, the heating operation of false twist texturers mainly relies on the structure of a heating chamber and a tube. Specifically, the filament to be heated is drawn through a tube located inside the heating chamber. The heat generated by the heating chamber heats the sidewalls of the tube, and the heat is then transferred between the sidewalls of the tube and the filament to achieve the purpose of heating. This heating method is widely used in the industry because of its relatively simple structure and ease of implementation.

[0003] However, the tubes used in current false-twist texturing machines are mainly divided into two categories. Both types of tubes have insurmountable technical defects in practical applications, seriously affecting the processing quality of the yarn, equipment operating efficiency, and production cost control. Specific problems are as follows: One type is a straight tube. Because the contact between the sidewall of a straight tube and the yarn is non-adherent, the yarn can only form a localized, loose contact or no contact with the sidewall when passing through the tube, failing to establish a stable and efficient heat transfer path. This problem directly leads to two consequences: Firstly, the heat transferred from the heating chamber to the sidewall of the tube is difficult to fully and evenly transfer to the yarn, resulting in insufficient heating temperature and poor heating uniformity, which in turn causes quality problems such as insufficient yarn elasticity and color difference in dyeing, seriously affecting the product's market competitiveness. Secondly, to compensate for the low heat transfer efficiency, the heating power of the heating chamber needs to be increased to ensure the heating requirements of the yarn, which undoubtedly increases the energy consumption cost of the equipment, contradicting the current industrial advocacy of energy conservation and emission reduction. The other type is an arc-shaped tube. Compared to straight tubes, curved tubes, due to their curved structure, allow the curved sidewalls of the tube to form a tight, close contact with the wire, significantly improving heat transfer and solving, to some extent, the problems of insufficient and uneven heating of the wire. However, this type of tube also faces two major problems during long-term use: First, because the wire always maintains close contact and relative friction with a fixed position on the curved sidewall of the tube as it travels through the tube, the wear rate at this contact point is much faster than that of other parts of the tube. Over time, the contact point will gradually wear thin and even break. When the wear exceeds the service threshold, the tube can no longer work normally and must be replaced. This not only increases the replacement frequency and spare parts cost of the tube, but also reduces production efficiency due to equipment downtime for tube replacement. Second, because the wire is always in contact with the fixed position of the tube, other non-contact positions of the tube are idle for a long time. Dust in the air, oil stains and other impurities ejected by the wire during processing will gradually accumulate in these non-contact positions. As the amount of impurities accumulates, they gradually occupy the internal space of the tube, eventually clogging the internal channels, affecting the normal flow of the wire, and even causing equipment malfunctions. To solve this problem, the tube needs to be removed from the heating box for cleaning periodically. This process is not only time-consuming and labor-intensive, increasing the workload of operators, but it also causes equipment downtime, further reducing production efficiency and affecting the company's continuous production plan.

[0004] In summary, both types of tubes used for heating yarn in current false twist texturing machines, whether straight or curved, have their own technical defects and cannot simultaneously meet the requirements of high-quality yarn heating, low-energy operation of the equipment, long tube life, and efficient continuous operation of the equipment. These problems have become key bottlenecks restricting the improvement of processing efficiency and product quality of false twist texturing machines, and a new technical solution is urgently needed to solve the above-mentioned technical pain points.

[0021] The technical solution of this utility model has the following significant beneficial effects:

[0022] 1. The wire to be heated passes through at least a partially arc-shaped tube assembly, allowing the wire to adhere tightly to the inner wall of the tube assembly. Under the action of the heating assembly, the tube assembly is heated, and the wire passing through the tube assembly is heated efficiently through heat transfer. The driving assembly drives the transmission assembly to rotate, so that the tube rotates around its circumference through the cooperation of the second transmission structure and the first transmission structure. This causes the position where the wire adheres tightly to the inner wall of the tube assembly to change. Thus, as the wire passes through the tube assembly, it makes close contact and friction with different positions on the inner wall of the tube assembly, preventing continuous friction at a fixed contact point. Therefore, the tube assembly is unlikely to break, eliminating the need for replacement and effectively improving production efficiency. In addition, the change in the position where the wire is in close contact with the inner wall of the tube assembly allows the wire to come into contact with all parts of the inner wall of the tube assembly. The wire will carry away impurities from all parts of the inner wall of the tube assembly, preventing impurities from accumulating. Therefore, there is no need to disassemble the tube assembly for cleaning periodically, which can also improve production efficiency.

[0023] 2. When the transmission assembly rotates, since the number of left-hand and right-hand worm gear structures is equal, the opposing axial forces exerted by the two on the transmission assembly can cancel each other out, effectively preventing the transmission assembly from moving or tending to move in a certain axial direction under the force.

[0032] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0033] To address the issues of easy wear and tear on the tube body 42 and the accumulation of impurities on the inner wall requiring regular cleaning, this application proposes a wire heating mechanism. Figure 1 This is a front view of the wire heating mechanism in an embodiment of this utility model. Figure 2This is a side view of the heating assembly and the tube assembly in an embodiment of this utility model. Figure 3 for Figure 2 An enlarged diagram of point A in the middle, as shown below. Figures 1 to 3 As shown, the wire heating mechanism may include: a tube assembly 4 that is at least partially arc-shaped, the tube assembly 4 having a first transmission structure 41, the first transmission structure 41 including at least a worm gear structure 411; a heating assembly 3 for heating the tube assembly 4, the tube assembly 4 being used to pass through the wire 100 and to heat the wire 100 under the action of the heating assembly 3; a transmission assembly 2, the transmission assembly 2 having a second transmission structure 21, the second transmission structure 21 including at least a worm gear structure 211, the second transmission structure 21 cooperating with the first transmission structure 41 for transmission; a driving assembly 1, the driving assembly 1 for driving the transmission assembly 2 to rotate, so as to drive the tube assembly 4 to rotate around its own circumference through the cooperation of the second transmission structure 21 and the first transmission structure 41; the tube assembly 4 may be an even number, the number of worm gear structures 211 is equal to the number of tube assembly 4, the multiple worm gear structures 211 include left-hand worm gear structures 2111 and right-hand worm gear structures 2112, the number of left-hand worm gear structures 2111 is equal to the number of right-hand worm gear structures 2112.

[0034] The wire 100 to be heated passes through at least part of the arc-shaped tube assembly 4, allowing the wire 100 to adhere tightly to the inner wall of the tube assembly 4. Under the action of the heating assembly 3, the tube assembly 4 is heated, and the wire 100 passing through the tube assembly 4 is heated efficiently through heat transfer. The driving assembly 1 drives the transmission assembly 2 to rotate, so that the tube 42 rotates around its own circumference through the cooperation of the second transmission structure 21 and the first transmission structure 41. This causes the position where the wire 100 adheres tightly to the inner wall of the tube assembly 4 to change. In this way, when the wire 100 passes through the tube assembly 4, it will make close contact and rub against different positions on the inner wall of the tube assembly 4, rather than rubbing against a fixed contact position continuously. Therefore, the tube assembly 4 is unlikely to be damaged and does not need to be replaced, effectively improving production efficiency. Furthermore, the change in the position where the wire 100 is in contact with the inner wall of the tube assembly 4 allows the wire 100 to contact all points on the inner wall of the tube assembly 4. The wire 100 carries away impurities from these points, preventing their accumulation. Therefore, it is unnecessary to periodically disassemble the tube assembly 4 for cleaning, thus improving production efficiency. Additionally, when the transmission assembly 2 rotates, since the number of left-hand worm gear structures 2111 and right-hand worm gear structures 2112 is equal, their opposing axial forces on the transmission assembly 2 can cancel each other out, effectively preventing the transmission assembly 2 from moving or tending to move in a specific axial direction under the applied force. Figure 1As shown, the wire heating mechanism may include: a tube assembly 4, a heating assembly 3, a transmission assembly 2, and a drive assembly 1. Wherein, as... Figure 2 As shown, the tube assembly 4 is at least partially arc-shaped, and the tube assembly 4 is used for the wire 100 to pass through from the inside. During this process, the wire 100 can form a tight and close contact with the inner wall of the arc-shaped tube assembly 4, which can significantly improve the heat transfer effect between the two. Figure 3 As shown, the tube assembly 4 may have a first transmission structure 41. The transmission assembly 2 has a second transmission structure 21, which cooperates with the first transmission structure 41 for transmission. The drive assembly 1 is used to drive the transmission assembly 2 to rotate, so as to drive the tube assembly 4 to rotate around its own circumference through the cooperation of the second transmission structure 21 and the first transmission structure 41. The heating assembly 3 is used to heat the tube assembly 4, thereby heating the threaded wire 100 under the action of the heating assembly 3.

[0035] The cooperation between the first transmission structure 41 and the second transmission structure 21 can take many forms, as long as it can drive the tube assembly 4 to rotate around its own circumference. In one feasible implementation, such as... Figure 3 As shown, the first transmission structure 41 and the second transmission structure 21 can be coupled through a worm gear structure 411 for transmission. For example, the first transmission structure 41 may include at least a worm gear structure 411; the second transmission structure 21 may include at least a worm gear structure 211. Using this method, one drive component 1 can easily and conveniently drive multiple tube components 4 to rotate simultaneously.

[0036] As a feasible option, such as Figure 1 As shown, the drive assembly 1 may include a motor 11 and a reduction mechanism 12. The motor 11 is connected to the transmission assembly 2 via the reduction mechanism 12. For example, the reduction mechanism 12 may be a worm gearbox with a large reduction ratio. In this way, the high speed of the motor 11 can be reduced to a relatively low rotation, requiring only a small amount of rotation of the tube assembly 4 each time.

[0037] As a feasible option, such as Figure 2 As shown, the tube assembly 4 may include: a tube 42 that is at least partially arc-shaped and a sleeve 43 with a worm gear structure 411 connected to the tube 42. The tube 42 may be an arc with a radius of R. The sleeve 43 and the tube 42 are fixedly connected. The sleeve 43 may be fitted onto the tube 42, such as at the end of the tube 42. In other feasible embodiments, the worm gear structure 411 may also be directly formed on the outer wall of the tube 42.

[0038] In one feasible implementation, a drive component 1 can drive a tube component 4 to rotate via a transmission component 2.

[0039] In another feasible implementation, Figure 4 This is a schematic diagram illustrating the cooperation between the transmission assembly and the tube assembly in an embodiment of this utility model. Figure 1 and Figure 4 As shown, a drive component 1 can drive multiple tube body components 4 to rotate via a transmission component 2. Furthermore, for example, Figure 5 for Figure 4 An enlarged diagram of point B in the middle, as shown below. Figure 5 As shown, the number of tube body assemblies 4 can be even, and the number of worm gear structures 211 is equal to the number of tube body assemblies 4. The multiple worm gear structures 211 include left-handed worm gear structures 2111 and right-handed worm gear structures 2112, with the number of left-handed worm gear structures 2111 equal to the number of right-handed worm gear structures 2112. In this embodiment, when the transmission assembly 2 rotates, since the number of left-handed worm gear structures 2111 and right-handed worm gear structures 2112 is equal, their opposing axial forces on the transmission assembly 2 can cancel each other out, effectively preventing the transmission assembly 2 from moving or tending to move in a certain axial direction under the applied force.

[0040] In one specific implementation, such as Figure 4 and Figure 5 As shown, the transmission assembly 2 may include: a transmission shaft 22, on which at least one worm gear member 23 having a worm structure 211 is fixedly connected. The worm gear member 23 may be sleeved and fixed on the transmission shaft 22. The worm gear member 23 has at least one left-handed worm structure 2111 and at least one right-handed worm structure 2112; the left-handed worm structure 2111 and the tube assembly 4 are used in a one-to-one manner; the right-handed worm structure 2112 and the tube assembly 4 are used in a one-to-one manner. Furthermore, the number of left-handed worm structures 2111 and right-handed worm structures 2112 on each worm gear member 23 is equal, thereby avoiding axial force on the transmission shaft 22 between adjacent worm gear members 23.

[0041] There can be one or more heating components 3. For example... Figure 1 As shown, one heating element 3 can cooperate with multiple tube assemblies 4 to perform heating. One heating element 3 can correspond to one drive shaft 22, and the corresponding drive shafts 22 of adjacent heating elements 3 can be connected in series, such as through a coupling 24. In this way, one drive assembly 1 can drive a row of drive shafts 22 corresponding to the heating elements 3 to rotate.

[0042] In one feasible implementation, such as Figure 1As shown, the heating assembly 3 includes: a heating chamber 31 with a receiving cavity for loading a heat transfer liquid; and a heating element for heating the heat transfer liquid. A tube assembly 4 is at least partially inserted into the receiving cavity. The heat transfer liquid can contact the tube assembly 4 to heat it; alternatively, the heat transfer liquid can be heated and converted into a gaseous state to heat the tube assembly 4. For example, the heat transfer liquid can be water, which can be heated and converted into water vapor to heat the tube assembly 4, thus eliminating the need for the tube assembly 4 to contact the heat transfer liquid. The heating chamber 31 can be tilted, and the heat transfer liquid only needs to fill the bottom of the heating chamber 31.

[0043] In one feasible embodiment, the wire heating mechanism may include a limiting component, which is rotatably connected to the tube assembly 4 about the axial direction of the tube assembly 4 to limit the radial direction of the tube assembly 4. When the driving component 1 drives the tube assembly 4 to rotate about its own circumference, the limiting component may not rotate, thereby limiting the radial direction of the tube assembly 4 and preventing its first transmission structure 41 from disengaging from the second transmission structure 21. The limiting component may be fixedly installed. Furthermore, the limiting component may also limit the axial direction of the tube assembly 4 to prevent it from moving arbitrarily along the axial direction. For example, as... Figure 3 As shown, the end of the tube assembly 4 and the end of the limiting assembly can be connected by a recessed portion that mates with a spherical part, and the interiors of the two are connected so that the wire 100 can pass through the limiting assembly and enter the tube assembly 4. Specifically, the end of the sleeve 43 and the end of the limiting assembly can be connected by a recessed portion that mates with a spherical part; the end of the sleeve 43 can also be connected to a connecting tube 44 by means such as a threaded connection, and the connecting tube 44 and the end of the limiting assembly can be connected by a recessed portion that mates with a spherical part.

[0044] This application also proposes a false twist texturer, which may include a yarn heating mechanism as described above.
