Description

Technical Field

[0001] This utility model relates to the field of yarn processing technology, specifically a yarn stretching and setting device. Background Technology

[0002] Yarn is a continuous fabric made of fibers, a basic raw material used in textile processing such as weaving and knitting. It is typically made from natural fibers (such as cotton, wool, and silk) or chemical fibers (such as polyester, nylon, and polypropylene) through a spinning process. Yarn comes in various forms, including filaments and staple fibers, and its fineness is usually expressed by its count (e.g., 10-count, 20-count, etc.); the higher the count, the finer the yarn. The main use of yarn is as a raw material for textiles, used in the production of various fabrics, clothing, and household goods.

[0003] Stretch setting is essential for yarns. For example, it improves yarn strength and stability. Through stretch setting, the fiber molecular chains rearrange under the action of tensile force, strengthening the intermolecular forces and making the bonds between fibers tighter. This improves the yarn's breaking strength and abrasion resistance. Stretch setting can also eliminate internal stress generated during the spinning process, making the yarn structure more stable and reducing problems such as yarn deformation and breakage caused by stress release during subsequent processing and use, thus improving the quality and stability of the yarn.

[0004] Yarn stretching typically requires stretching and setting equipment. However, current equipment has several shortcomings: First, the tension adjustment is not flexible or convenient enough. Different types and specifications of yarn require different tension forces, but existing equipment struggles to adapt quickly to these changes, leading to inefficiency when processing different yarns. Second, the tension monitoring accuracy is insufficient. Even if some equipment has some monitoring capabilities, the accuracy is inadequate to accurately reflect the actual stress state of the yarn, easily resulting in excessive or insufficient tension. Summary of the Invention

[0005] The purpose of this invention is to provide a yarn stretching and setting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A yarn stretching and setting device includes a machine base, a first roller, a second roller, and a third roller. The first roller and the second roller are rotatably mounted on the machine base via a frame, and the third roller is mounted on the frame via a lifting structure. When the lifting structure is in operation, the height of the third roller can be adjusted.

[0008] A material cylinder is rotatably mounted on the machine base via a bracket. A drive assembly is also mounted on the machine base. The drive assembly is connected to the first roller shaft, the second roller shaft, and the material cylinder. When the drive assembly is running, the first roller shaft, the second roller shaft, and the material cylinder all rotate.

[0009] The second roller and the third roller are connected by a transmission structure. Under the action of the transmission structure, when the second roller rotates, the third roller will rotate as long as it is adjusted to any height.

[0010] The bracket is equipped with a tension monitoring component. When the height of the No. 3 roller is adjusted, the tension monitoring component can detect the tension value of the yarn in real time.

[0011] As a further embodiment of this utility model:

[0012] The lifting structure includes a guide rail disposed on the frame and a slider slidably disposed on the guide rail, and the No. 3 roller shaft is rotatably disposed on the slider;

[0013] An electric push rod is vertically mounted on the frame, and the output end of the electric push rod is fixedly connected to the slider.

[0014] As a further improvement of this utility model:

[0015] The drive assembly includes a motor, a first sprocket disposed at one end of the material cylinder, and a second sprocket disposed on the first roller shaft;

[0016] The first sprocket and the second sprocket are connected by a chain, and the motor is fixed on the machine base and its output end is fixedly connected to one end of the material cylinder.

[0017] As a further improvement of this utility model:

[0018] A first transmission wheel is provided on the first roller shaft, and a second transmission wheel is provided on the second roller shaft. The first transmission wheel and the second transmission wheel are connected by a first belt.

[0019] As a further improvement of this utility model:

[0020] The transmission structure includes a rotating shaft, a first connecting rod, and a second connecting rod, one end of which is rotatably connected to the rotating shaft.

[0021] The other end of the first connecting rod is rotatably connected to the second roller shaft, and the other end of the second connecting rod is rotatably connected to the third roller shaft.

[0022] As a further improvement of this utility model:

[0023] The No. 2 roller is equipped with a No. 3 transmission wheel, and the No. 4 transmission wheel is equipped with a No. 4 transmission wheel. The No. 3 transmission wheel and the No. 4 transmission wheel are connected by a second belt.

[0024] The No. 3 roller shaft is equipped with a No. 5 transmission wheel, and the No. 6 transmission wheel is equipped with a No. 6 transmission wheel. The No. 5 transmission wheel and the No. 6 transmission wheel are connected by a third belt.

[0025] As a further improvement of this utility model:

[0026] The tensile monitoring component includes a shaped frame, a sleeve, and a sliding rod that slides with the sleeve. The shaped frame is fixed to the support.

[0027] The bottom of the slide bar is provided with a U-shaped frame, and rollers are rotatably mounted on the U-shaped frame;

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] The lifting structure allows for height adjustment of the No. 3 roller, enabling quick and convenient changes in yarn tension. When the drive assembly is running, the No. 1 roller, the No. 2 roller, and the feed cylinder all rotate to feed the yarn. Under the action of the transmission structure, the No. 3 roller will rotate along with the No. 2 roller at any height to facilitate the feeding operation. When the power of the drive assembly and traction equipment (not shown in the attached diagram) is constant, the yarn tension will change when the No. 3 roller is adjusted in height. The tension monitoring component can monitor the yarn tension in real time and accurately, thus reflecting the yarn tension value.

[0034] This application, through the cooperation of the drive component, lifting structure, transmission structure and tension monitoring component, can not only flexibly and conveniently adjust the tension force as needed to improve efficiency, but also accurately reflect the actual stress state of the yarn, avoiding situations where the tension force is too large or too small.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] Please see Figures 1-9 In this embodiment of the present invention, a yarn stretching and shaping device includes a machine base 1, a first roller 2, a second roller 3, and a third roller 4. The first roller 2 and the second roller 3 are rotatably mounted on the machine base 1 via a frame 5. The third roller 4 is mounted on the frame 5 via a lifting structure. When the lifting structure is in operation, the height of the third roller 4 can be adjusted.

[0048] A material cylinder 7 is rotatably mounted on the machine base 1 via a bracket 6. A drive assembly is mounted on the machine base 1. The drive assembly is connected to the first roller 2, the second roller 3, and the material cylinder 7 respectively. When the drive assembly is running, the first roller 2, the second roller 3, and the material cylinder 7 all rotate.

[0049] The second roller 3 and the third roller 4 are connected by a transmission structure. Under the action of the transmission structure, when the second roller 3 rotates, the third roller 4 will rotate as long as it is adjusted to any height.

[0050] The bracket 6 is equipped with a tension monitoring component. When the height of the third roller 4 is adjusted, the tension monitoring component can detect the tension value of the yarn in real time.

[0051] In this scheme, the lifting structure can adjust the height of the No. 3 roller 4 to different heights, thereby quickly and conveniently changing the tension of the yarn. When the drive component is running, the No. 1 roller 2, the No. 2 roller 3, and the material cylinder 7 all rotate to feed the yarn. Under the action of the transmission structure, the No. 3 roller 4 will rotate with the No. 2 roller 3 when adjusted to any height to cooperate with the feeding operation. When the power of the drive component and the traction device (not shown in the attached figure) is constant, the tension of the yarn will change when the height of the No. 3 roller 4 is adjusted. The tension monitoring component can monitor the tension of the yarn in real time and accurately, thereby reflecting the tension value of the yarn.

[0052] As a further embodiment of this utility model, the lifting structure includes a guide rail 8 disposed on the frame 5 and a slider 9 slidably disposed on the guide rail 8, and the third roller shaft 4 is rotatably disposed on the slider 9.

[0053] An electric push rod 10 is vertically mounted on the frame 5, and the output end of the electric push rod 10 is fixedly connected to the slider 9.

[0054] In this embodiment, since the slider 9 is slidably mounted on the guide rail 8 and the output end of the electric push rod 10 is fixedly connected to the slider 9, the slider 9 will move vertically when the output end of the electric push rod 10 moves.

[0055] Since the No. 3 roller shaft 4 is rotatably mounted on the slider 9, the No. 3 roller shaft 4 will move vertically along with the slider 9, thereby adjusting different heights and being able to rotate freely.

[0056] As a further embodiment of this utility model, the drive assembly includes a motor 11, a first sprocket 12 disposed at one end of the material cylinder 7, and a second sprocket 13 disposed on the first roller shaft 2;

[0057] The first sprocket 12 and the second sprocket 13 are connected by a chain 14. The motor 11 is fixed on the machine base 1 and its output end is fixedly connected to one end of the material cylinder 7.

[0058] A first transmission wheel 15 is provided on the first roller shaft 2, and a second transmission wheel 16 is provided on the second roller shaft 3. The first transmission wheel 15 and the second transmission wheel 16 are connected by a first belt 17.

[0059] In this embodiment, since the output end of the motor 11 is fixedly connected to one end of the material cylinder 7, and the material cylinder 7 is rotatably mounted on the bracket 6, the material cylinder 7 will rotate when the motor 11 is started.

[0060] Since the No. 1 sprocket 12 fixed on the material cylinder 7 and the No. 2 sprocket 13 fixed on the No. 1 roller shaft 2 are connected by a chain 14, the No. 1 roller shaft 2 will rotate when the material cylinder 7 rotates.

[0061] Since the first transmission wheel 15 fixed on the first roller shaft 2 and the second transmission wheel 16 fixed on the second roller shaft 3 are connected by the first belt 17, when the first roller shaft 2 rotates, the second roller shaft 3 will rotate accordingly.

[0062] As a further embodiment of this utility model, the transmission structure includes a rotating shaft 18, a first connecting rod 19, and a second connecting rod 20, one end of the first connecting rod 19 and the second connecting rod 20 being rotatably connected to the rotating shaft 18.

[0063] The other end of the first connecting rod 19 is rotatably connected to the second roller shaft 3, and the other end of the second connecting rod 20 is rotatably connected to the third roller shaft 4.

[0064] In this embodiment, such as Figure 3 As shown, since the rotating shaft 18 is rotatably connected to the first connecting rod 19 and the second connecting rod 20 respectively, and the first connecting rod 19 and the second connecting rod 20 are rotatably connected to the second roller shaft 3 and the third roller shaft 4 respectively, when the second roller shaft 3 is height adjusted, the included angle between the first connecting rod 19 and the second connecting rod 20 will change, but the distance between the rotating shaft 18 and the second roller shaft 3 and the third roller shaft 4 remains unchanged, and the rotation of the rotating shaft 18 is not affected when the third roller shaft 4 is adjusted to different heights.

[0065] As a further embodiment of this utility model, a third transmission wheel 21 is provided on the second roller 3, and a fourth transmission wheel 22 is provided on the rotating shaft 18. The third transmission wheel 21 and the fourth transmission wheel 22 are connected by a second belt 23.

[0066] The No. 3 roller 4 is provided with a No. 5 transmission wheel 24, and the No. 6 transmission wheel 25 is provided on the rotating shaft 18. The No. 5 transmission wheel 24 and the No. 6 transmission wheel 25 are connected by a third belt 26.

[0067] In this embodiment, since the No. 3 transmission wheel 21 fixed on the No. 2 roller shaft 3 and the No. 4 transmission wheel 22 fixed on the rotating shaft 18 are connected by the second belt 23, the rotating shaft 18 will rotate when the No. 2 roller shaft 3 rotates.

[0068] Furthermore, since the No. 5 transmission wheel 24 fixed on the No. 3 roller shaft 4 and the No. 6 transmission wheel 25 fixed on the rotating shaft 18 are connected by the third belt 26, the No. 3 roller shaft 4 will rotate along with the rotating shaft 18.

[0069] As a further embodiment of this utility model, the tensile monitoring component includes a shaped frame 27, a sleeve 28, and a slide rod 29 that slides with the sleeve 28. The shaped frame 27 is fixed on the bracket 6.

[0070] The bottom of the slide bar 29 is provided with a U-shaped frame 30, and a roller 31 is rotatably mounted on the U-shaped frame 30;

[0071] A spring 32 is provided inside the sleeve 28, and the two ends of the spring 32 abut against the top of the slide rod 29 and the inner top of the sleeve 28, respectively.

[0072] The irregular frame 27 has a vertically opened sliding groove 33, and a sliding seat 34 is slidably disposed in the sliding groove 33. The sliding seat 34 is fixedly connected to the sleeve 28.

[0073] A pressure sensor 35 is provided on the top of the irregular frame 27, and the top of the sleeve 28 abuts against the pressure sensor 35.

[0074] In this embodiment, such as Figure 4 As shown, since the sleeve 28 is fixedly connected to the slide block 34 which is slidably disposed in the slide groove 33, and the top of the sleeve 28 abuts against the pressure sensor 35, when the sleeve 28 is subjected to a larger vertical upward force, the force of the sleeve 28 pressing against the pressure sensor 35 will also increase, and the pressure sensor 35 can monitor the change of pressure value in real time.

[0075] like Figure 7 As shown, when the height of roller 4 increases, the tension of the yarn will increase. At this time, the thrust of the yarn on roller 31 will increase. Since the thrust of the yarn on roller 31 can be divided into horizontal and vertical directions, the vertical thrust of roller 31 will increase.

[0076] Since the slide bar 29 and the sleeve 28 are in sliding engagement, and the roller 31 is fixedly connected to the bottom of the slide bar 29 through the U-shaped frame 30, under the action of the yarn thrust, the roller 31 will push the sleeve 28 vertically upward through the U-shaped frame 30, the slide bar 29 and the spring 32.

[0077] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.
