Description

Technical Field

[0001] The utility model relates to textile equipment, in particular to an air fiber texturing machine Background Technique

[0002] With the increasing demand for personalized textiles, textile enterprises have more and more requirements for the specifications of yarns. The demand for some specifications of yarns is small, and the market supply is scarce, resulting in a significant increase in the procurement cost of enterprises. If the existing yarns can be deformed into the required yarns, the production cost of enterprises will be greatly reduced. Therefore, in order to save raw materials, the long fiber yarns in stock usually need to be air-textured to obtain fluffiness and good hand feeling to meet the market demand. This product is called air textured yarn. Air textured yarn is made by using the jet method to inject compressed air through a texturing nozzle to interlace the fiber bundle, forming irregular kinked coils, making the fiber bundle have a fluffy looped yarn and some characteristics similar to staple fibers. The machine for interlacing the fiber bundle in the textile industry is generally called an air texturing machine

[0003] The Chinese invention patent application with the publication number of CN115323559A discloses a preparation method of a core-sheath structured chemical fiber fluff yarn, which relates to the textile field. The method includes: winding the core yarn around the first pre-stretching roller and feeding it into the humidifying module through the first input roller; winding the sheath yarn around the second pre-stretching roller and feeding it into the humidifying module through the second input roller; after the core yarn and the sheath yarn are combined into one strand on the humidifying module, they pass through the texturing nozzle and the setting oven in sequence, and then are output as a preliminary air textured yarn through the output roller; the preliminary air textured yarn is introduced into a raising machine for raising treatment and then the core-sheath structured chemical fiber fluff yarn is exported, and finally the core-sheath structured chemical fiber fluff yarn exported from the raising machine is wound around a coiling roller for collecting yarns; the fluff yarn prepared by this application has a high production efficiency, can not only control the density and distribution of the fluff, but also has plump fluff and soft hand feeling, and also has stable mechanical properties due to the protection of the sheath yarn for the core yarn. The preparation method is simple and efficient and can be mass-produced

[0004] In the preparation device adopted by the above method, rollers are used as input and output devices. Each roller is equipped with an apron carrier and a top roller. The apron carrier presses the upper top roller onto the roller, and the top roller rotates together with the roller. There is a certain difference between the rotational speed of the roller-top roller and the moving speed of the yarn. As a result, sliding friction occurs between the roller and the yarn, and the yarn contacts a fixed position on the surface of the roller. Therefore, after long-term contact between the roller and the yarn, due to the friction of the yarn, indentations will be generated on the surface of the roller, and the yarn will get stuck in the indentations, increasing the contact area between the yarn and the roller surface and increasing the friction force, which easily causes wear of the yarn and reduces the quality of the yarn. Therefore, in equipment using a roller drafting device, a yarn transfer mechanism is often required to avoid indentations on the top roller, thereby ensuring the processing quality of the yarn. In this way, although the quality of the yarn is improved, the number of vulnerable parts is correspondingly increased, increasing the production cost. Summary of the Invention

[0005] Utility Model Objective: The objective of the present utility model is to provide an air fiber texturing machine that saves costs and can avoid mutual wear between roller parts and yarn. Secondly, when the yarn breaks, the device operation can be stopped in a timely manner.

[0006] Technical Solution: The air fiber texturing machine described in the present utility model includes a raw yarn stand and a frame. Multiple spindle positions are provided on the frame. The spindle positions include a feeding device, a texturing device, and an output device arranged in sequence. Both the feeding device and the output device adopt a wire winding device. A wire dividing roller and a disc body for winding the yarn are rotatably connected to the wire winding device. Among them, the lower wire winding device is provided with a driving device, and the upper roller can adjust the angle.

[0007] Based on the above technical solution, the feeding device and the output device adopt a wire winding device instead of the structure of rollers and top rollers. The yarn is not driven by the top roller pressing on the roller, but is wound around the wire dividing roller and the disc body for multiple turns. The upper wire dividing roller adjusts the downward inclination angle, which can separate the yarn wound on the wire dividing roller from each other in the axial direction of the roller, and further separate the yarn wound on the disc body from each other in its axial direction. In this way, multiple turns of yarn are in contact with the lower disc body at the same time, and it is not easy for them to have relative sliding, avoiding mutual wear, and there is no need to set up a special yarn transfer mechanism to adjust the position of the yarn, which not only avoids the loss of the roller parts and the yarn caused by wear, but also reduces the device, further saving costs.

[0008] Preferably, the wire winding device includes a mounting plate. Guide wire porcelain parts are respectively provided at the top and bottom of the mounting plate. The wire dividing roller and the disc body are connected between the guide wire porcelain parts.

[0009] Setting the guide wire porcelain parts can better guide the yarn in and out of the wire winding device.

[0010] Preferably, a switch for controlling the start and stop of the driving device is provided on the mounting plate.

[0011] Preferably, a humidifying device and a texturing nozzle are provided in the texturing device.

[0012] Preferably, the feeding device includes two feeding lines for feeding the core yarn and the skin yarn into the texturing device respectively. The core yarn sequentially enters the humidifying device and the texturing nozzle, and the skin yarn directly enters the texturing nozzle.

[0013] The core yarn is humidified by the humidifying device first and then enters the texturing nozzle together with the skin yarn, which can enhance the texturing effect of the core yarn.

[0014] Preferably, a yarn cutting device for cutting the yarn is provided between the raw yarn bobbin holder and the feeding device.

[0015] Preferably, a detection device for detecting whether the yarn is broken is provided between the feeding device and the texturing device and after the output device; the detection device is electrically connected to the yarn cutting device; when the yarn is broken, the detection device activates the yarn cutting device and cuts off the power supply of the texturing machine.

[0016] By providing the detection device, it can be timely detected whether the yarn entering the texturing device is broken, or whether the yarn output by the output device is broken. If a break occurs, the circuit of the yarn cutting device is conducted to immediately cut off the yarn, preventing the feeding device from further pulling the yarn on the raw yarn bobbin holder to the spindle position for processing, and cutting off the power supply of the entire texturing machine except the yarn cutting device.

[0017] Preferably, a winding device is provided after the output device.

[0018] Preferably, the winding devices of the multiple spindle positions are arranged side by side or in parallel.

[0019] Preferably, an oiling device is provided between the output device and the winding device.

[0020] Setting the oiling device can lubricate the yarn, reduce the friction between the yarn and the machine, and prevent the yarn from being worn.

[0021] Preferably, spindle positions and raw yarn bobbin holders are symmetrically arranged on both sides of the frame.

[0022] Through the above settings, the yarn can be processed on both sides of the frame at the same time, improving the space utilization rate.

[0023] Advantageous effects: Compared with the prior art, the beneficial effects of the present utility model are as follows: By the wire winding device pulling the yarn, the contact area between the yarn and it is increased, relative sliding is not easy to occur, and the wear between the two is reduced; secondly, through the cooperation of the detection device and the yarn cutting device, when it is found that the yarn is broken, the yarn at the outlet of the raw yarn bobbin holder can be timely cut off, avoiding the continuous introduction of yarn that cannot be processed and causing accumulation.

[0026] As shown in the figure, the air fiber texturing machine provided by the present utility model includes a raw yarn frame 1 and a frame 4. A plurality of spindle positions are provided on the frame 4, and each spindle position can process one or more continuous yarns. The yarn on the single spindle position sequentially passes through a feeding device 6, a texturing device 8, and an output device 11 arranged in sequence. The feeding device 6 and the output device 11 both adopt a wire winding device. A splitting roller 16 and a disc body 17 for winding the yarn are rotatably connected to the wire winding device. Among them, the lower disc body 17 is connected to a driving device 20, and the upper splitting roller 16 can adjust its angle.

[0027] A plurality of spindle positions can be arranged side by side, Figure 1 Only one spindle position is shown in the figure, and the other spindle positions are not shown on the inner and outer sides in the direction perpendicular to the paper.

[0028] A wire cutting device 5 is provided between the raw yarn frame 1 and the feeding device 6. The wire cutting device 5 can cut the yarn to prevent the feeding device 6 from continuously pulling the silk thread on the raw yarn frame 1.

[0029] The feeding device 6 includes two feeding lines that respectively draw out the yarn from the raw yarn frame 1 and feed the core yarn 2 and the skin yarn 3 into the texturing device 8.

[0030] The feeding device 6 and the output device 11 both adopt a wire winding device. The wire winding device includes a mounting plate 15. Guide wire porcelain parts 18 are respectively provided at the top and bottom of the mounting plate 15. The splitting roller 16 and the disc body 17 are located between the two guide wire porcelain parts 18 on the mounting plate 15. The yarn passes through the upper guide wire porcelain part 18, sequentially bypasses the upper splitting roller 16 and the lower disc body 17, then winds back to the splitting roller 16, and forms a circle on the two splitting rollers 16 and the disc body 17. After that, it winds several circles on the splitting roller 16 and the disc body 17, and finally winds out from the splitting roller 16 and passes through the lower guide wire porcelain part 18. The splitting roller 16 and the disc body 17 are driven to be connected through the yarn. The yarn is equivalent to a transmission belt. The splitting roller 16 adjusts its downward inclination to a suitable angle according to the thickness and material of the yarn, so that the several circles of yarn on the splitting roller 16 and the disc body 17 can be separated at intervals to prevent the yarn from winding. The driving device 20 connected to the disc body 17 drives it to rotate, drives the yarn to move, and then drives the splitting roller 16 to rotate, thereby realizing the transmission of the yarn.

[0031] A switch 19 for controlling the start and stop of the control drive device 20 is provided on the mounting plate 15.

[0032] A first detection device 7 is provided between the feeding device 6 and the texturing device 8. When the first detection device 7 detects a yarn break, the yarn cutting device 5 is activated to cut the yarn.

[0033] A humidifying device 9 and a texturing nozzle 10 are provided inside the texturing device 8. The core yarn 2 sequentially enters the humidifying device 9 and the texturing nozzle 10, and the sheath yarn 3 directly enters the texturing nozzle 10. A gas input channel is provided inside the texturing nozzle 10. After the two-way yarns of the core yarn 2 and the sheath yarn 3 are subjected to interlacing processing by the compressed air in the nozzle 10, a bulked air-jet yarn is finally formed and output from the nozzle 10 to the output device 11. The output device 11 has only one line.

[0034] A second detection device 12, an oiling device 14, and a winding device 13 are sequentially provided after the output device 11.

[0035] The second detection device 12 has the same function as the first detection device 7 and will not be elaborated here. Both detection devices adopt existing devices, such as the detection device disclosed in CN204342170U or other detection devices that can both activate a certain line and cut off the power supply of the entire device. As long as the alarm connected to it is replaced with the yarn cutting device 5 or a yarn cutting device 5 is added to the line connected to the alarm, when a yarn break occurs, the yarn cutting device 5 can be activated to cut the yarn, preventing the feeding device 6 from continuously introducing yarn from the raw yarn stand 1, and at the same time, the power supply of the entire texturing machine except the yarn cutting device 5 can be cut off.

[0036] The winding devices 13 with multiple spindles are arranged side by side or in parallel. Figure 1 The situation where the winding devices 13 with multiple spindles are arranged in parallel with upper and lower sealing layers is shown.

[0037] Spindles and raw yarn stands 1 are symmetrically arranged on both sides of the frame 4, which can improve the space utilization rate.
