Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a false twist texturing machine composed of a plurality of processing positions and a conveying device. Background Art

[0002] The structure of a false twist texturing machine is disclosed in a number of prior arts, including CN1882487B.

[0003] In known false twist texturing machines, a plurality of processing positions are arranged side by side, each of which has a plurality of processing devices in order to draw, texturize, stretch and wind a fed filament from a raw filament cake into a bobbin.

[0004] In this type of false twist texturing machine, up to 384 processing positions are arranged side by side. Each processing position has at least two conveying devices that realize conveying and stretching of the filaments at different speeds.

[0005] Another prior art, CN101634065B, discloses two different configurations of a conveying device.

[0006] One is a winding type structure, which has a godet roller and a separator roller. The godet roller is connected to a separate motor. In order to guide the filament, the filament is guided on the rotatable housing of the godet roller and the separator roller in a multiple winding manner.

[0007] In order to avoid overloading of the electric drive device in any working state, CN101448726B discloses a conveying device provided with a winding detector. The winding detector is maintained so that one end thereof has a small spacing relative to the housing of the godet roller. When a wire break occurs, the filaments gather and overlap on the godet roller, thereby contacting the end of the detector, triggering the movement of the end of the detector, and then interrupting the current supplied to the motor.

[0008] According to CN101634065B, another type is a clamping type structure. In this structure, the filament is guided in the clamping gap between the drive shaft and the pressure roller. The pressure roller is held on the circumference of the driven drive shaft by a movable tension arm. The filament is guided on the circumference of the drive shaft in a partially wound manner and is continuously conveyed by the combined action of the drive shaft and the pressure roller.

[0009] The above two conveying devices have their own advantages and disadvantages. The clamping conveying device has lower manufacturing costs than the winding conveying device, mainly because the current winding conveying device requires a separate motor to drive. In addition, multiple motors require more complex control components and control systems to control. The winding conveying device causes less damage to the filament than the clamping conveying device, thanks to its use of the friction between the surface of the guide roller and the filament to transport the filament.

[0010] The cost of components and the performance index of the final filament are the key points of attention in the development of false twist texturing machine technology. Therefore, a conveying device combining the respective advantages of the above two conveying devices is needed. Utility Model Content

[0011] In order to overcome the above-mentioned defects of the prior art, the utility model provides a false twist texturing machine.

[0012] According to an embodiment of the utility model, a false twist texturing machine composed of multiple processing positions, each of the processing positions has a raw wire rack for placing raw material filament cakes, a first conveying device for extracting the filaments from the raw wire rack, a heating device for heat treating the filaments, a cooling device for cooling the filaments, a false twisting device for false twisting the filaments, a winding device for winding the filaments into shape, and a second conveying device for extracting the filaments from the false twisting device and conveying them to the winding device, wherein the first conveying device and / or the second conveying device are configured as a winding structure; multiple first conveying devices are driven by the first transmission part in a concentrated manner through magnetic force, and / or multiple second conveying devices are driven by the second transmission part in a concentrated manner through magnetic force; the first transmission part and the second transmission part extend along the length direction of the false twist texturing machine.

[0013] The beneficial effect is to reduce the cost of materials and energy consumption, because the first conveying device and / or the second conveying device do not need a separate drive motor to drive a single position, and thus do not need a switch device for disconnecting the motor in the event of a broken yarn. At the same time, the characteristic of using a winding structure for yarn conveying is retained to ensure minimal damage to the yarn.

[0014] According to another embodiment of the utility model, the cylindrical surface of the first conveying device is used to wind the filament, and the end face of the first conveying device facing the first transmission part is provided with a circle of driven magnet circle composed of multiple magnets, and the magnetic poles of adjacent magnets are opposite; the first transmission part has a first transmission shaft and multiple active magnet circles arranged along the length direction of the first transmission shaft, the active magnet circle is composed of multiple magnets, and the magnetic poles of adjacent magnets are opposite; the driven magnet circle is vertically arranged relative to the active magnet circle, and the edge of the driven magnet circle is close to the edge of the active magnet circle.

[0015] The driven magnet ring is coupled to the first conveying device and cooperates with the active magnet ring on the first transmission shaft. The rotating active magnet ring drives the rotation of the driven magnet ring through the attraction property of opposite magnetic poles with the driven magnet ring. Multiple active magnet rings having the same number as the first conveying device are used to realize simultaneous driving of multiple first conveying devices.

[0016] According to another embodiment of the utility model, the false twist texturing machine has left and right sides; the second conveying device on the left side and the second conveying device on the right side are arranged on both sides of the second transmission part; the cylindrical surface of the second conveying device on the left side is used to wind the filament, and the end face of the second conveying device on the left side facing the second transmission part is provided with a circle of driven magnet circles composed of a plurality of magnets, and the magnetic poles of adjacent magnets are opposite; the cylindrical surface of the second conveying device on the right side is used to wind the filament, and the end of the second conveying device on the right side facing the second transmission part is provided with a circle of driven magnet circles composed of a plurality of magnets, and the magnetic poles of adjacent magnets are opposite; the second transmission part has a second transmission shaft and a plurality of active magnet circles arranged along the length direction of the second transmission shaft, the active magnet circles are composed of a plurality of magnets, and the magnetic poles of adjacent magnets are opposite; the edge of the driven magnet circle on the left side and the edge of the driven magnet circle on the right side are both close to the edge of the active magnet circle.

[0017] The beneficial effect of this embodiment is that one transmission part drives the second conveying devices on the left and right sides to rotate simultaneously. By sharing one transmission part on both sides, the overall material cost and energy consumption cost of the false twist texturing machine are further reduced.

[0018] Taking into account the principle of better magnetic transmission efficiency, according to another embodiment of the utility model, the driven magnet circles on the left and right sides are parallel to each other and parallel to the plumb line passing through the center of the second transmission shaft, and the driven magnet circles on the left and right sides are vertically arranged relative to the active magnet circle.

[0019] Taking into account the principle of optimal yarn path, according to another embodiment of the utility model, the driven magnet circles on the left and right sides are mirror-symmetrical with respect to a plumb line passing through the center of the second transmission shaft, and are arranged vertically with respect to the active magnet circle.

[0020] In order to further obtain better magnetic transmission efficiency, according to another embodiment of the utility model, one of the active magnetic ring and the driven magnetic ring is composed of a sector magnet, and the other is composed of a rectangular magnet.

[0021] The utility model also provides a conveying device, which is multiple and arranged side by side and has a cylindrical surface for winding filaments. The multiple conveying devices are driven by a transmission part through magnetic force in a concentrated manner; the transmission part extends along the side-by-side arrangement direction of the multiple conveying devices.

[0022] This embodiment also has the advantage of reducing the cost of materials and energy consumption.

[0023] With reference to the following description and accompanying drawings, the specific embodiments of the present application are disclosed in detail, indicating the way in which the principles of the present application can be adopted. It should be understood that the embodiments of the present application are not limited in scope.

[0031] Figure 1 The false twist texturing machine shown is exemplary and is configured with two zones, A and B. The zone A on the left and the zone B on the right are substantially symmetrical to each other.

[0032] The following takes area B as an example to briefly introduce the general structure of the false twist texturing machine. The raw materials of the false twist texturing machine are placed on the raw yarn rack 2. The raw yarn rack 2 is a vertical frame structure, and a plurality of cake placement bases are fixed in the horizontal direction for stacking raw material filament cakes (POY, pre-oriented yarn). Using a knotter, two raw material filament cakes 1 adjacent to each other in the horizontal direction are connected end to end. After the filaments of one of the filament cakes are used up, the other filament cake takes over and continues to supply raw materials uninterruptedly. The raw material filaments are guided to the top of the raw yarn rack 2, and then guided to the first conveying device 9. After the filaments 4 are wound several times on the circumferential surface of the first conveying device 9 and the filament separation roller 10 at the same time, they enter the first heating device 5.

[0033] By virtue of the friction between the circumferential surface of the first conveying device 9 and the filament 4, the rotational movement of the first conveying device 9 causes the filament 4 to be drawn out from the raw yarn rack 2. The function of the separating roller 10 is to separate the several "filament loops" on the first conveying device 9 from each other.

[0034] After the filament 4 enters the first heating device 5 and is heated at a high temperature, it enters the cooling device 6 for contact passive cooling or active cooling. The difference between passive cooling and active cooling is whether a cooling medium (such as coolant, cooling air, etc.) is used to force the heated filament to cool. The cooling distance required by the active cooling cooling device 6 is shorter.

[0035] In the filament processing flow, the false twisting device 7 is located behind the cooling device 6. The false twisting device 7 applies false twist to the filament. In this process, the filament is first twisted and then untwisted. After the filament is twisted, it is heated to set the shape, and then cooled. After cooling, the twist applied is untwisted. Since the bending shape of the filament is fixed after heating and cooling after twisting, the filament still maintains the bending shape after untwisting.

[0036] The second conveying device 12 having a higher rotation speed than the first conveying device 9 is located after the false twisting device 7. In this embodiment, the first conveying device and the second conveying device have the same structure. The wire separation roller 11 is installed adjacent to the second conveying device 12. The filament 4 is stretched between the first conveying device 9 and the second conveying device 12.

[0037] This embodiment utilizes the second heating device 17 installed substantially vertically to perform secondary heating or shaping heating on the filaments, which is particularly suitable for the treatment of polyester filaments.

[0038] The filaments coming out of the second heating device 17 bypass the bottom of the false twist texturing machine and enter the winding device upward through the third conveying device. The third conveying device is constructed with a drive shaft 18, a pressure roller 19 and a tension arm 20. The filaments are guided in the clamping gap between the drive shaft 18 and the pressure roller 19. The pressure roller 19 is held on the circumference of the driven drive shaft 18 by a movable tension arm 20. The third conveying device of this structure is very suitable for maintaining a constant filament conveying tension in the post-processing area, and even when the operator manually drops the bobbin, there will be no sudden tension reduction in the post-processing area.

[0039] The filaments enter a winding device that is arranged in multiple layers vertically and side by side horizontally. Each winding device has a friction roller 16, a bobbin 15 pressed against the friction roller 16, and a cradle 14 that supports the bobbin 15.

[0040] Except for the common parts on the A and B sides to be explained below, the A side and the B side are relatively independent in function and have the same structure, and are basically mirror-symmetrical. The A side and the B side are each provided with a first transmission part 8 to drive the corresponding first conveying device 9. However, the second conveying device 22 on the A side and the second conveying device 12 on the B side have the same structure and share the second transmission part 13. The second conveying device 22 is arranged near the wire separation roller 21 and parallel to the wire separation roller 21. The second transmission part 13 can drive the second conveying devices 12 and 22 on both sides thereof to rotate simultaneously. The transmission parts 8 and 13 do not form a mechanical connection with the conveying devices 9, 12, and 22. Different from the technical solutions in the prior art, the conveying devices 9, 12, and 22 are no longer directly driven by motors. Optionally, the second conveying device 22 on the A side and the second conveying device 12 on the B side can also be driven by their respective corresponding transmission parts to obtain relatively independent rotation speeds on both sides AB.

[0041] The false twist texturing machine on either side is composed of a plurality of processing positions arranged in parallel along a direction perpendicular to the paper surface. Each of the processing positions is mainly composed of a raw yarn rack, a first conveying device, a first heating device, a cooling device, a false twisting device, a second conveying device, a second heating device, a third conveying device and a winding device. In other embodiments different from this embodiment, the second heating device and the third conveying device may not be provided. In other embodiments, only one conveying device is configured as a winding type.

[0042] In order to further explain the relationship between the transmission part and the conveying device, the following will be combined with Figures 2 to 4 to explain.

[0043] Figure 2 Shows Figure 1The positional relationship between the second conveying device and the second transmission part in the illustrated embodiment. As an exemplary illustration, in this embodiment, six second conveying devices are selected on both sides of the second transmission part 13, and the second conveying devices on one side are marked as 12.1-12.6, and the second conveying devices on the other side are marked as 22.1-22.6.

[0044] The second transmission part 13 has a second transmission shaft 23, which is arranged along the direction (perpendicular to the Figure 1 The left end of the second transmission shaft 23 is connected to a driving source not shown to provide power for rotating the second transmission shaft 23.

[0045] Each of the second conveying devices is configured to have a cylindrical surface 24 and end surfaces 25, 26 at both ends. The filament is wound around the cylindrical surface 24 for multiple times and is conveyed by means of the contact friction between the filament and the cylindrical surface. The end surface 26 facing the second conveying portion 13 is provided with a driven magnet ring 31. Figure 4 The driven magnet ring 31.1 is composed of a plurality of sector-shaped magnets, and the magnetic poles of adjacent magnets are opposite. Figure 4 for Figure 2 A perspective view of the illustrated embodiment.

[0046] The second transmission part 13 also has a plurality of active magnet rings 27.1-27.6, which are fixedly mounted on the second transmission shaft 23 at positions corresponding to the second conveying devices on both sides. Adjacent active magnet rings are separated by a certain distance. The active magnet rings 27.1-27.6 are composed of a plurality of rectangular magnets arranged at intervals, and the magnetic poles of adjacent magnets are opposite. The active magnet ring 27.1 is embedded in the circumferential surface of the annular part 30.1.

[0047] The active magnet rings 27.1-27.6 rotate with the second transmission shaft 23. In order to drive the second conveying devices (12.1-1.6, 22.1-22.6) on both sides by magnetic force, taking one position as an example, one active magnet ring 27.1 is arranged corresponding to the two driven magnet rings 31.1 on the left and right, and the two driven magnet rings 31.1 are parallel to each other and arranged vertically relative to the one active magnet ring 27.1, and the edges of the two driven magnet rings 31.1 are close to the edge of the one active magnet ring 27.1. Under the effect of the attraction between the opposite magnetic poles of the magnets in the driven magnet ring and the active magnet ring, the driven magnet ring is driven to rotate, so that the conveying device is driven to rotate.

[0048] The transmission shaft driven by the motor drives all the conveying devices on both sides of the false twist texturing machines A and B to rotate simultaneously through magnetic force.

[0049] Figure 3 Shows Figure 1 The positional relationship between the first conveying device and the first transmission part in the illustrated embodiment.

[0050] According to this embodiment, the first conveying device 9.1-9.6 is installed only on one side of the first transmission part 8, and its single structure is the same as the second conveying device. The first transmission part 8 has a first transmission shaft 28 extending along the arrangement direction of the first conveying devices 9.1-9.6 and active magnet circles 29.1-29.6 corresponding to the positions of each of the first conveying devices. The active magnet circles 29.1-29.6 are composed of a plurality of magnets arranged, and the magnetic poles of adjacent magnets are opposite; the driven magnet circle is arranged vertically relative to the active magnet circle, and the edge of the driven magnet circle is close to the edge of the active magnet circle.

[0051] Although, in Figure 1 In the embodiment of the present invention, the first conveying device is configured as a winding structure, the second conveying device is also configured as a winding structure, a plurality of the first conveying devices are driven by the first transmission part in a centralized manner through magnetic force, and a plurality of the second conveying devices are driven by the second transmission part in a centralized manner through magnetic force, but the embodiments of the present invention are not limited thereto. In other possible embodiments, only one of the first conveying device and the second conveying device is a winding structure, which also means that only one of the two is driven by the transmission part in a centralized manner through magnetic force.

[0052] The conveying device does not need to be driven by a separate motor and is not troubled by problems such as motor overload when the wire is broken. Therefore, there is no need to set a switch device for cutting off the power supply.

[0053] Figure 5 An embodiment schematically shows the positional relationship between the transmission part and the conveying device; Figure 6 Another embodiment of the positional relationship between the transmission part and the conveying device is schematically shown.

[0054] according to Figure 5, the second conveying devices 22.1 and 12.1 are respectively located on both sides of the second transmission part 13. With the center of the second transmission shaft 23 of the second transmission part 13 as a reference, the plumb line passing through the center is marked as 32. The second conveying devices 22.1 and 12.1 are parallel to each other and parallel to the plumb line 32. The end face 26 of the second conveying device 22.1 is parallel to the end face 26 of the second conveying device 12.1, and the two end faces 26 are parallel to the plumb line 32. At the same time, the two end faces 26 are respectively perpendicular to the circularly arranged active magnet ring 27.1, which also means that the two driven magnet rings 31.1 located on the end faces 26 are also respectively perpendicular to the active magnet ring 27.1. This design follows the principle of maximum magnetic transmission efficiency.

[0055] As an option, taking into account the principle of optimal yarn path, according to Figure 6 , the end face 26 of the second conveying device 12.1 is inclined relative to the plumb line 32 so that the yarn enters the second conveying device 12.1 at a small bending angle. Similarly, the second conveying device 22.1 on the other side is arranged symmetrically with the second conveying device 12.1 relative to the plumb line 32. The two end faces 26 are respectively perpendicular to the circularly arranged active magnet rings 27.1.

[0056] The embodiment of the utility model further provides a conveying device. The difference from the above embodiment is that the conveying device of this embodiment can also be used in other textile machines besides the false twist texturing machine.

[0057] The present application is described above in conjunction with specific embodiments, but it should be clear to those skilled in the art that these descriptions are exemplary and are not intended to limit the scope of protection of the present application. Those skilled in the art can make various modifications and variations to the present application based on the spirit and principles of the present application, and these modifications and variations are also within the scope of the present application.

[0058] The preferred embodiments of the present application are described above with reference to the accompanying drawings. Many features and advantages of these embodiments are clear from this detailed description, and therefore the appended claims are intended to cover all such features and advantages of these embodiments that fall within their true spirit and scope. In addition, since many modifications and changes are easily conceivable to those skilled in the art, the embodiments of the present application are not intended to be limited to the precise structures and operations illustrated and described, but all suitable modifications and equivalents that fall within their scope may be covered.
