Description

Technical Field

[0001] This invention relates to textile machinery, and more specifically, to a polyester texturing machine. Background Technology

[0002] Texturing machines are core textile equipment that obtain elastic yarns by stretching, false twisting, and texturing yarns. Existing texturing machines are mainly divided into two categories: small and large.

[0003] Patent number CN116377630A discloses a polyester texturing machine. This texturing machine is a small texturing machine with a compact size and low price. However, due to the limitation of structural layout, the heating box is small. In order to ensure the heating effect of the yarn, the texturing speed is low and the production efficiency is low.

[0004] Patent number CN209779091U discloses a false twist texturing machine with altered yarn path in an upper heating box. This texturing machine is a large texturing machine with a large equipment size. Therefore, a larger heating box can be selected to increase the texturing speed. However, the equipment occupies a large space and has a high manufacturing cost.

[0005] In addition, in order to facilitate the yarn to pass through the heating box, the heating box of traditional texturing machines is mostly semi-enclosed. However, this design will affect the heating efficiency of the yarn in the heating box. Therefore, the yarn is now in contact with the surface of the heating rail in the heating box. Although this can improve the heating efficiency of the yarn, the friction of the yarn when it is running in the heating box will increase, which will increase the risk of yarn breakage when false twisting.

[0006] Therefore, there is an urgent need to design a new type of texturing machine that has the size of a small texturing machine and the efficiency of a large texturing machine. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a polyester texturing machine. By adjusting the original layout of the texturing machine and optimizing the structure of the heating box, a small-volume and high-efficiency texturing machine can be manufactured.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a polyester texturing machine, comprising a raw yarn frame and an n-type frame, wherein the n-type frame is respectively fixed along the yarn running direction with a first drafting plate, a texturing heat box, a first yarn guide, a cold rail, a false twister, a network nozzle, a setting heat box, a second yarn guide, a roller, a yarn probe, an oil roller, a third yarn guide, and a winding device;

[0009] The raw yarn frame is located on one side of the frame where the first drafting plate is located and is lower than the first drafting plate. The deformation heat box is located on the upper part of the frame and is inclined upward. The setting heat box is located on the side of the winding device. After the yarn passes through the setting heat box, it is turned by the second guide and the third guide and then wound by the winding device.

[0010] The deformation heat box is at least one straight heat box, and multiple wire feed rods are fixed inside the straight heat box. Multiple second ceramic guide rings are fixed inside the wire feed rods along their length. The yarn passes through the wire feed rods and the second ceramic guide rings. The inner hole of the wire feed rod is coaxial with the inner hole of the second ceramic guide ring, and the size of the inner hole of the wire feed rod is larger than the size of the inner hole of the second ceramic guide ring.

[0011] Furthermore, the linear heating box includes a box body, inside which a biphenyl box is fixed, and a heating zone is formed inside the biphenyl box. Multiple sleeves are fixed side by side inside the box body, with both ends of the sleeves penetrating the biphenyl box and communicating with both ends of the box body. The threaded rod corresponds one-to-one with the sleeve and penetrates both ends of the sleeve.

[0012] Furthermore, a connecting plate is fixed to the side of the housing facing the original wire frame. The connecting plate includes a threaded hole corresponding to the sleeve. The diameter of the threaded hole is larger than the diameter of the sleeve. The wire feed rod includes a threaded section. The inner side of the threaded section abuts against the side of the housing and is connected to the threaded hole by threads.

[0013] Furthermore, a first ceramic guide ring is embedded and fixed at both ends of the feed screw, and the first ceramic guide ring and the second ceramic guide ring are coaxial.

[0014] Furthermore, the side wall of the feed screw includes multiple notches adapted to the second ceramic guide ring, and cuts are provided on both sides of the notches. The second ceramic guide ring is inserted into the notch and fixed, and the second ceramic guide ring is tightly fitted with the notch.

[0015] Furthermore, the deformable heat box consists of two straight heat boxes, each including a hinge seat located at its lower edge. The two straight heat boxes are hinged together by the hinge seat. Both straight heat boxes are fixed to the upper part of the frame. The included angle between the two straight heat boxes is an obtuse angle. A fifth yarn guide is fixed between the two straight heat boxes. After the yarn passes through the yarn feed rod in one straight heat box, it is turned by the fifth yarn guide and passes through the yarn feed rod of the other straight heat box.

[0016] Furthermore, it also includes a flexible connecting sleeve, which is located at the connection of the two straight-line heat boxes and is respectively fitted and fixed to the two straight-line heat boxes. A wire guide frame is fixed between the two straight-line heat boxes. The wire guide frame includes a connecting rod corresponding to the wire feeding rod of the straight-line heat box. The lower end of the connecting rod is inserted into the area enclosed by the connecting sleeve, and the fifth wire guide is fixed to the lower end of the connecting rod.

[0017] Furthermore, two L-shaped brackets are fixed to the upper part of the box body. The L-shaped brackets are provided with guide holes. The L-shaped brackets of the two straight hot boxes are staggered. The guide wire frame includes a connector. The two ends of the connector abut against the two innermost L-shaped brackets. The two ends of the connector are fixed with connecting shafts. The two connecting shafts pass through the guide holes of the L-shaped brackets of the two straight hot boxes on the same side, and the two staggered L-shaped brackets are fixed with nuts.

[0018] Furthermore, a twist stopper is fixed between the first drawing plate and the lowest point of the deformation heat box. A second drawing plate and a third drawing plate are also fixed on the side of the frame away from the original yarn frame. The second drawing plate and the third drawing plate are located on the upper and lower sides of the network nozzle, respectively. The cold rail corresponds one-to-one with the wire feed rod in a straight heat box.

[0019] The first guide wire, cold rail, false twister, second drafting plate, network nozzle, third drafting plate, and setting heat box are arranged in sequence from top to bottom. The second guide wire, roller, wire probe, upper oil roller, and third guide wire are located directly below the winding device. A fourth guide wire is fixed between the third guide wire and the winding device.

[0020] Furthermore, the length L of the texturing machine ranges from 2200mm to 2300mm, and the height H ranges from 3800mm to 3900mm.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The texturing machine has a length L range of 2200mm-2300mm and a height H range of 3800mm-3900mm. Compared with large texturing machines (height 5000mm, width 3500mm), its volume is reduced by more than 40%, and it is only slightly larger than small texturing machines (height 3500mm, width 2200mm). It has a compact size, high space utilization, and can be adapted to the limited space of small and medium-sized workshops, reducing installation and transportation costs.

[0023] 2. The heat in the heating zone is evenly transferred to the yarn located in the yarn feeder after being conducted through the sleeve and the yarn feeder. Since the yarn feeder is a closed structure with only two ends connected (due to the yarn feed at both ends), its heating efficiency is higher than that of the traditional semi-closed heat box. In addition, the yarn feeder and the box body adopt a detachable design with threaded connection. When threading the yarn, the yarn can be passed through the yarn feeder outside the deformation heat box before the yarn feeder is installed with the deformation heat box. This not only facilitates the yarn threading operation, but also facilitates the maintenance of the yarn feeder. It can also solve the problem of the yarn feeder channel being unable to be maintained in the fully enclosed heat box.

[0024] 3. The yarn is conveyed through the second ceramic guide ring inside the wire feeder, which avoids the yarn from contacting the inner wall of the wire feeder, thereby effectively improving the yarn conveying speed. Furthermore, due to the high thermal efficiency of the fully enclosed heat box, it is possible to manufacture a small-volume, high-texturing-speed equipment, which has the size of a small texturing machine while also having the texturing speed of a large texturing machine.

[0037] 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.

[0038] Example 1:

[0039] like Figures 1 to 8 As shown, this embodiment discloses a polyester texturing machine, including a raw yarn frame 1 and a frame 4. The frame 4 is fixed in sequence along the running direction of the yarn 20, including a first drafting plate 2, a twist stopper 3, a texturing heat box 5, a first yarn guide 6, a cooling rail 7, a false twister 8, a second drafting plate 9, a network nozzle 10, a third drafting plate 11, a setting heat box 12, a second yarn guide 13, a roller 14, a yarn probe 15, an upper oil roller 16, a third yarn guide 17, a fourth yarn guide 18, and a winding device 19.

[0040] like Figure 1As shown, the raw yarn frame 1 is located on the side of the frame 4 facing the first drafting plate 2 and is lower than the first drafting plate 2. The raw yarn frame 1 is used to unwind the raw yarn. The frame 4 is generally n-shaped, with the left side of the frame 4 being higher than the right side. The deformation heat box 5 is used for the heat deformation of the yarn. The deformation heat box 5 is located on the upper part of the frame 4 and is inclined upward. The left side of the deformation heat box 5 is fixed to the left side of the frame 4. The anti-twist device 3 is located between the first drafting plate 2 and the lowest point of the deformation heat box 5. The yarn is guided at the anti-twist device 3 and enters the deformation heat box 5. The anti-twist device 3, the deformation heat box 5 and the first yarn guide 6 are arranged in a straight line. The function of the anti-twist device 3 is to eliminate the excess twist generated by the yarn during the drafting process, prevent the twist from being carried into the deformation heat box 5, and ensure that the yarn is in a no-twist or low-twist state when it enters the deformation heat box 5, thus ensuring the effect of subsequent heating and shaping and false twist deformation.

[0041] like Figure 1 As shown, the first yarn guide 6, the cold rail 7, the false twister 8, the second drafting plate 9, the network nozzle 10, the third drafting plate 11, and the shaping heat box 12 are fixed to the left side of the frame 4 from top to bottom. The top-down arrangement makes the texturing machine structure more compact and helps to reduce the overall length.

[0042] The first yarn guide 6 is used to turn the yarn. The number of cooling rails 7 corresponds to the number of yarns. The entire cooling rail 7 is made of metal. The inside of the cooling rail 7 has a U-shaped yarn feeding groove. Each yarn feeding groove can pass through. The cooling rail 7 quickly and evenly cools the yarn after it has been heated and shaped by the deformation heat box 5, fixes the thermal deformation structure of the yarn, and provides a stable foundation for subsequent false twist deformation.

[0043] The number of false twisters 8 is the same as that of the cooling rail 7. The false twisters 8 can apply a precise and controllable twist to the yarn after it has been cooled by the cooling rail 7, so that the fiber will be permanently crimped and deformed, ultimately giving the yarn elasticity and bulkiness, which is suitable for the texturing processing needs of yarns such as polyester and spandex.

[0044] After false twisting, the yarn passes through the network nozzle 10, and the high-pressure airflow of the network nozzle 10 forms a periodic network knot on the yarn surface, which firmly entangles the crimped fibers generated by false twisting into bundles, fixes the elastic structure of the yarn, and improves the bundle properties and subsequent processing adaptability.

[0045] The setting heat box 12 is used to set the polyester yarn after false twisting. Specifically, it performs secondary heating and setting on the polyester yarn after false twisting and network entanglement, permanently locking the yarn's crimped elastic structure and network knot shape, eliminating internal stress, and ensuring stable yarn elasticity and uniform dimensions. The setting heat box 12 is vertically arranged and located on the side of the winding device 19. This layout can further reduce the overall length of the texturing machine.

[0046] After passing through the setting heat box 12, the yarn 20 is turned by the second guide 13 and the third guide 17 and then wound by the winding device 19. Specifically, the second guide 13, roller 14, yarn probe 15, upper oil roller 16 and the third guide 17 are located directly below the winding device 19. This structural layout can further reduce the overall length of the texturing machine.

[0047] A fourth yarn guide 18 is fixed between the third yarn guide 17 and the winding device 19. After the yarn is guided by the fourth yarn guide 18, it is wound by the winding drum corresponding to the winding device 19, and the yarn is textured.

[0048] like Figure 1 As shown, the length L of the texturing machine ranges from 2200mm to 2300mm, and the height H ranges from 3800mm to 3900mm. In this embodiment, the texturing machine has a length L=2200mm and a height H=3800mm. Compared with a large texturing machine (height 5000mm and width 3500mm), its volume is reduced by more than 40%, and it is only slightly larger than a small texturing machine (height 3500mm and width 2200mm). It is compact in size, has high space utilization, and can be adapted to the limited space of small and medium-sized workshops, reducing installation and transportation costs.

[0049] Traditional heating boxes are semi-open heating boxes that use biphenyl gas phase heating. Biphenyl gas phase heating is an indirect heating technology that uses biphenyl (a mixture of biphenyl and diphenyl ether, commonly known as "Dowson liquid") as the heating medium. The core principle is to use the phase change (liquid → gas) of biphenyl for heat transfer. The heating tubes of the heating box heat the biphenyl medium, and the vaporized biphenyl vapor fills the internal cavity of the heating rail. The heat is then evenly transferred to the yarn through the wall of the heating rail to achieve yarn heating and shaping.

[0050] like Figures 1 to 4 As shown, the modified heating box 5 in this embodiment also uses biphenyl vapor phase heating to heat the yarn. The straight heating box 21 includes a box body 211, a biphenyl box 213 is fixed inside the box body 211, a heating zone 214 is formed inside the biphenyl box 213, and multiple sleeves 212 are fixed side by side inside the box body 211. The two ends of the sleeves 212 penetrate the biphenyl box 213 and are connected to the two ends of the box body 211. The heating pipe of the heating box heats the biphenyl medium, and the vaporized biphenyl vapor fills the heating zone 214. The heat is evenly transferred to the yarn inside the sleeve 212 through the wall of the thin-walled metal sleeve 212.

[0051] In this embodiment, the heating box is a fully enclosed, straight-line heating box 21. Multiple threaded rods 25 are fixed inside the straight-line heating box 21. Specifically, each threaded rod 25 corresponds to a sleeve 212 and passes through both ends of the sleeve 212. A connecting plate 216 is fixed to the side of the box body 211 facing the original wire frame 1. The connecting plate 216 includes a threaded hole corresponding to the sleeve 212, and the diameter of the threaded hole is larger than the diameter of the sleeve 212. Each threaded rod 25 includes a threaded section 254. The inner side of the threaded section 254 abuts against the side of the box body 211 and is threadedly connected to the threaded hole. The sleeve 212 is a closed metal pipe with only two ends connected, and its wall thickness is 0.5mm. The threaded rod 25 is also a closed metal pipe with only two ends connected. The yarn is fed through a threading rod 25 with a wall thickness of 1mm. The heat in the heating zone 214 is conducted through the sleeve 212 and the threading rod 25 and then evenly transferred to the yarn located in the threading rod 25. Since the threading rod 25 is a closed structure with only two ends connected (due to the threading at both ends), its heating efficiency is higher than that of the traditional semi-closed heating box. Furthermore, the threading rod 25 and the box body 211 adopt a detachable design with a threaded connection. When threading, the yarn can be passed through the threading rod 25 outside the deformation heating box 5 before the threading rod 25 is installed with the deformation heating box 5. This not only facilitates the threading operation of the yarn but also facilitates the maintenance of the threading rod 25 and solves the problem of the inability to maintain the threading channel of the fully enclosed heating box.

[0052] like Figures 4 to 6 As shown, multiple second ceramic guide rings 26 are fixed inside the wire feed rod 25 along its length. The yarn 20 passes through the wire feed rod 25 and the second ceramic guide rings 26. The inner hole of the wire feed rod 25 is coaxial with the inner hole of the second ceramic guide ring 26, and the inner hole size of the wire feed rod 25 is larger than the inner hole size of the second ceramic guide ring 26. The yarn is conveyed through the second ceramic guide rings 26 inside the wire feed rod 25, avoiding contact between the yarn and the inner wall of the wire feed rod 25. This effectively improves the yarn conveying speed. Furthermore, due to the high thermal efficiency of the fully enclosed heat box, it is possible to manufacture a small-volume, high-texturing-speed device, giving it the size of a small texturing machine while also achieving the texturing speed of a large texturing machine.

[0053] like Figure 4 and Figure 5 As shown, the yarn feeder 25 has a first ceramic guide ring 253 embedded in both ends. The first ceramic guide ring 253 and the second ceramic guide ring 26 are coaxial. The two first ceramic guide rings 26 are used for guiding the yarn feeder 25 at the inlet and the outlet respectively. The first ceramic guide ring 253 and the second ceramic guide ring 26 are coaxially arranged, and the friction coefficient between the yarn and the inner wall of the guide ring is very small, which greatly reduces the friction compared with the traditional hot rail contact yarn feeder. Combined with the stable temperature environment of the fully enclosed hot box, it can effectively improve its texturing efficiency.

[0054] Furthermore, the empty area located outside the biphenyl box 213 and inside the box body 211 is the insulation area 215, which is filled with insulation cotton.

[0055] like Figure 6 and Figure 7 As shown, the side wall of the wire feed rod 25 includes multiple notches 251 adapted to the second ceramic guide ring 26. The notches 251 have cuts 252 on both sides. The second ceramic guide ring 26 is inserted into the notch 251 and fixed. The second ceramic guide ring 26 is tightly fitted with the notch 251. The cuts 252 can be used to appropriately deform the notch 251. The width of the cuts 252 is 0.3mm, which can make the notch 251 produce an elastic deformation of 0.2-0.3mm, ensuring that the second ceramic guide ring 26 has no displacement under high-speed wire feeding. At the same time, the detachable design facilitates the replacement of the guide ring.

[0056] Example 2:

[0057] like Figures 9 to 11 As shown, the difference from Embodiment 1 is that the deformable heat box 5 consists of two straight heat boxes 21. Each straight heat box 21 includes a hinge seat 219 located at its lower edge. The two straight heat boxes 21 are hinged together by the hinge seat 219. Both straight heat boxes 21 are fixed to the upper part of the frame 4 so that the included angle between the two straight heat boxes 21 is an obtuse angle, preferably 140°. A fifth yarn guide 24 is fixed between the two straight heat boxes 21. After the yarn 20 passes through the yarn feed rod 25 in one straight heat box 21, it is turned by the fifth yarn guide 24 and passes through the other straight heat box 21. The yarn feeder 25 is equipped with two straight heating boxes 21. In the first embodiment, the length of the deformed heating box 5 is 1800mm, and the yarn feed distance in the heating box is 1800mm. In this embodiment, the lengths of the two straight heating boxes 21 are 1130mm and 830mm, respectively. Including the exposed space above the hinge of the two straight heating boxes 21, the yarn feed distance in the deformed heating box 5 in this embodiment is about 2100mm, which is much larger than the feed distance in the embodiment. It can be seen that compared with a single straight heating box 21, the yarn feeds a greater distance in the heating box, and the heating is more complete.

[0058] In Example 2, the length of the texturing machine is L=2200mm and H=3900mm. Its height is slightly higher than that of Example 1. Compared with the existing small texturing machine with a height of 3500mm and a width of 2200mm, it is only slightly higher in height. Compared with the existing large texturing machine with a height of 5000mm and a width of 3500mm, the size of the texturing machine in this example is much smaller than that of the large texturing machine. Its manufacturing cost is slightly higher than that of the small texturing machine but much lower than that of the large texturing machine.

[0059] like Figure 11As shown, the two straight heating boxes 21 form an exposed space above the hinge. This exposed space is covered by a flexible connecting sleeve 22. The flexible connecting sleeve 22 is located at the connection of the two straight heating boxes 21 and is fixed to each of the two straight heating boxes 21. The flexible connecting sleeve 22 is lined with heat insulation cotton. When the two straight heating boxes 21 are heated, the space inside the connecting sleeve 22 is also heated through heat conduction. Therefore, when the yarn is transferred from one straight heating box 21 to the other, its heat deformation performance will not be affected by a sharp drop in temperature.

[0060] A wire guide frame 23 is fixed between the two linear heating boxes 21. The wire guide frame 23 includes a connecting rod 233 corresponding to the wire feeding rod 25 of the linear heating box 21. The lower end of the connecting rod 233 is inserted into the area enclosed by the connecting sleeve 22. The fifth wire guide 24 is fixed to the lower end of the connecting rod 233. Specifically, two L-shaped brackets 217 are fixed on the upper part of the box body 211. The L-shaped brackets 217 are provided with guide holes 218. The L-shaped brackets 217 of the two linear heating boxes 21 are staggered. The wire guide frame 23 includes... The device includes a connector 231, whose two ends abut against two innermost L-shaped brackets 217. Connecting shafts 232 are fixed at both ends of the connector 231. The two connecting shafts 232 pass through guide holes 218 of the L-shaped brackets 217 on the same side of the two straight heating boxes 21, and are fixed by nuts to the two staggered L-shaped brackets 217. The fifth yarn guide 24 is used to guide the yarn between the two straight heating boxes 21, thereby ensuring that the yarn is transferred from one straight heating box 21 to the other.

[0061] In this embodiment, after disassembling the connecting rod 233 and the fifth wire guide 24, the two straight heating boxes 21 can also rotate along the hinge seat 219 to form a straight shape, which can meet the needs of other types of texturing machines.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
