Technical Field

[0001] This utility model relates to the field of yarn blending, specifically a yarn blending device. Background Technology

[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery, and is divided into short fiber yarn and continuous filament yarn.

[0003] In existing yarn blending processes, the feeding device needs to feed different yarns simultaneously. Since different yarns require different tensions, and the existing yarn tension can only be controlled as a whole row, not individually, it cannot meet the tension requirements of different yarns, thus affecting the quality of yarn blending. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a yarn blending device to solve the technical problem that when the current yarn blending is carried out, the feeding device needs to feed different yarns at the same time. Since different yarns require different tensions, and the existing yarn tension can only be controlled as a whole in a single row, not individually, it is impossible to meet the tension requirements of different yarns, thus affecting the quality of yarn blending.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A yarn blending device is designed, comprising:

[0006] A base, wherein connecting plates are fixedly connected to both sides of the middle part of the base surface, and a connecting column is fixedly connected between the two connecting plates;

[0007] A tension adjustment mechanism, disposed on the connecting column, is used to independently adjust the tension of the blended yarn. The tension adjustment mechanism includes:

[0008] A connecting cylinder, wherein an adjusting column is slidably connected to the bottom of the connecting cylinder, and a groove is provided at the bottom of the adjusting column, and a tensioning wheel is rotatably connected to the inner cavity of the groove through a bearing;

[0009] An adjusting screw is inserted through the middle of the connecting cylinder and placed in the inner cavity of the connecting cylinder. The adjusting screw is threadedly connected to the connecting cylinder. An adjusting plate is rotatably connected to the bottom of the adjusting screw through a bearing.

[0010] A spring is disposed at the bottom of the adjusting plate, and the bottom of the spring is fixedly connected to the end of the adjusting column away from the tensioning wheel.

[0011] Preferably, it further includes a locking mechanism for adjusting the position of the tension adjustment mechanism on the connecting column. The locking mechanism includes fixed plates fixedly connected to both sides of the connecting cylinder near the adjusting screw. A lower connecting seat is fixedly connected between the tops of the two fixed plates. An upper connecting seat is provided on the lower connecting seat. A first fixing bolt rotatably passes through the upper connecting seat and is threadedly connected to the surface of the lower connecting seat. Both the upper and lower connecting seats are U-shaped.

[0012] Preferably, the inner walls of both the upper and lower connecting seats are fixedly connected with anti-slip pads, and the anti-slip pads are elastic and integrally molded from rubber.

[0013] Preferably, both ends of the connecting cylinder are provided with limit holes, and a second fixing bolt is provided in each of the two limit holes. Both of the second fixing bolts are threadedly connected to the surface of the adjusting column.

[0014] Preferably, an inlet plate is fixedly connected to one side of the surface of the base, and the inlet plate has multiple inlet holes. Mounting plates are fixedly connected to both sides of the end of the base away from the inlet plate, and a limit roller is rotatably connected between the two mounting plates through a bearing.

[0015] Preferably, the head of the second fixing bolt is larger than the width of the limiting hole, and the head of the second fixing bolt abuts against the outer side of the connecting cylinder.

[0016] Preferably, the tensioning wheel has a first annular groove on its outer periphery, and the first annular groove is located in the middle of the outer periphery of the tensioning wheel.

[0017] Preferably, the outer periphery of the limiting roller is provided with a plurality of second annular grooves, and the plurality of second annular grooves are equidistantly distributed on the outer periphery of the limiting roller.

[0018] Preferably, a pressure sensor is fixedly installed at the middle of one end of the adjusting plate near the spring, and the end of the spring near the pressure sensor corresponds to the pressure sensor.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] Through the sliding connection structure between the connecting cylinder and the adjusting column, and in conjunction with the tensioning wheel rotating through the bearing in the groove, it can directly act on a single yarn. By rotating the screw to push the adjusting plate, the spring is compressed or released. Precise control of the position of the tensioning wheel allows for adjustment of the tension required by the tensioning wheel for a single yarn. This enables independent adjustment of the tension of a single yarn, ensuring that each yarn receives the appropriate tension. This fundamentally solves the problem of different tension requirements for different yarns and effectively improves the quality of yarn blending. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A yarn blending device, see [link to example]. Figures 1 to 3 ,include:

[0027] Base 1, with connecting plates 4 fixedly connected to both sides of the middle part of the surface of the base 1, and a connecting column 41 fixedly connected between the two connecting plates 4;

[0028] A tension adjustment mechanism, disposed on the connecting column 41, is used to independently adjust the tension of the blended yarn. The tension adjustment mechanism includes:

[0029] A connecting cylinder 42 is slidably connected to an adjusting column 43 at its bottom. The bottom of the adjusting column 43 is provided with a groove 46, and the inner cavity of the groove 46 is rotatably connected to a tensioning wheel 44 through a bearing.

[0030] An adjusting screw 47 is inserted through the middle of the connecting cylinder 42 and placed in the inner cavity of the connecting cylinder 42. The adjusting screw 47 is threadedly connected to the connecting cylinder 42. An adjusting plate 48 is rotatably connected to the bottom of the adjusting screw 47 through a bearing. The external dimensions of the adjusting plate 48 are adapted to the internal dimensions of the connecting cylinder 42, and the adjusting plate 48 is slidably connected in the inner cavity of the connecting cylinder 42.

[0031] Spring 49 is disposed at the bottom of adjusting plate 48, and the bottom of spring 49 is fixedly connected to the end of adjusting column 43 away from tension wheel 44.

[0032] During operation, the sliding connection between the connecting cylinder 42 and the adjusting column 43, along with the tensioning wheel 44 rotating within the groove 46 via a bearing, directly acts on a single yarn. Combined with the threaded connection between the adjusting screw 47 and the connecting cylinder 42, rotating the screw pushes the adjusting plate 48, thereby compressing or releasing the spring 49. This precise control of the tensioning wheel 44 position allows for adjustment of the tension required by the tensioning wheel 44 for a single yarn, enabling independent adjustment of the tension of each yarn. This ensures that each yarn receives a suitable tension, fundamentally solving the problem of varying tension requirements among different yarns and effectively improving the quality of yarn blending.

[0033] For details, see Figure 2 It also includes a locking mechanism for adjusting the position of the tension adjustment mechanism on the connecting column 41. The locking mechanism includes a fixing plate 64 fixedly connected to both sides of the connecting cylinder 42 near the adjusting screw 47. A lower connecting seat 6 is fixedly connected between the tops of the two fixing plates 64. An upper connecting seat 61 is provided on the lower connecting seat 6. A first fixing bolt 62 is rotatably passed through the upper connecting seat 61, and the first fixing bolt 62 is threadedly connected to the surface of the lower connecting seat 6. Both the upper connecting seat 61 and the lower connecting seat 6 are U-shaped.

[0034] During operation, the U-shaped design of the upper connecting seat 61 and the lower connecting seat 6 can clamp the connecting column 41. By rotating the first fixing bolt 62 to make it threadedly connected to the lower connecting seat 6, the position of the tension adjustment mechanism on the connecting column 41 can be locked or released. This facilitates flexible adjustment of the position of each tension adjustment mechanism, allowing different yarns to be on a more reasonable path during the blending process. This avoids tension adjustment deviations caused by fixed positions, further ensuring the quality of blending. At the same time, the number of tension adjustment mechanisms can be added or reduced according to the amount of yarn fed in, further improving the applicability and operational flexibility of the device.

[0035] Further, see Figure 2 The inner walls of both the upper connecting seat 61 and the lower connecting seat 6 are fixedly connected with anti-slip pads 63, and the anti-slip pads 63 are elastic. The anti-slip pads 63 are integrally molded from rubber material. The elastic material of the anti-slip pads 63 allows them to fit tightly against the connecting column 41 when in contact, increasing friction and preventing the tension adjustment mechanism from sliding on the connecting column 41 due to external forces such as yarn pulling after the tension adjustment mechanism position is adjusted. This ensures the stability and accuracy of tension adjustment, making the entire device more reliable during use and effectively preventing the yarn tension control from being affected by loose position, thereby further ensuring the stability of blended fabric quality.

[0036] It is worth noting that, see Figure 2 and Figure 3Both ends of the connecting cylinder 42 have limiting holes 5, and both limiting holes 5 communicate with the inner cavity of the connecting cylinder 42. Each limiting hole 5 contains a second fixing bolt 51, which is threadedly connected to the surface of the adjusting column 43. The head of the second fixing bolt 51 is larger than the width of the limiting hole 5, and the head of the second fixing bolt 51 abuts against the outer side of the connecting cylinder 42. When the adjusting column 43 slides within the connecting cylinder 42 to adjust the tension, the second fixing bolt 51 passes through the limiting hole 5 and is threadedly connected to the adjusting column 43, with its head abutting against the outer side of the connecting cylinder 42. The design of the outer side of the cylinder 42 abutting against each other can prevent the adjusting column 43 from sliding excessively and disengaging from the connecting cylinder 42. After the tension adjustment is completed, the head of the second fixing bolt 51 is made to abut against the outer side of the connecting cylinder 42 by turning the second fixing bolt 51. The friction between the head of the second fixing bolt 51 and the outer side of the connecting cylinder 42 locks the current position of the adjusting column 43, avoiding displacement of the adjusting column 43 due to fluctuations in the force of the spring 49. This ensures that the tension control of the yarn by the tensioning wheel 44 is always in a stable state, further enhancing the reliability of single yarn tension adjustment and preventing the quality of blended yarn from being affected by structural loosening.

[0037] It is worth noting that, see Figure 1 A yarn inlet plate 2 is fixedly connected to one side of the surface of the base 1. The yarn inlet plate 2 has multiple yarn inlet holes 21. Mounting plates 3 are fixedly connected to both sides of the surface of the base 1 away from the yarn inlet plate 2. A limiting roller 31 is rotatably connected between the two mounting plates 3 through bearings. The yarn inlet plate 2 on the base 1 initially positions different yarns through the multiple yarn inlet holes 21, so that each yarn is arranged in an orderly manner before entering the tension adjustment mechanism, avoiding yarn tangling and chaos. The limiting roller 31 is rotatably connected between the mounting plates 3 through bearings. Its outer circumference design can guide the yarn path. When the yarn passes through the limiting roller 31 after tension adjustment, the limiting roller 31 can perform secondary positioning and guidance of the yarn, ensuring that the yarn keeps running in a straight line during the blending process, reducing tension changes caused by yarn path deviation, and forming a complete yarn control path in conjunction with the tension adjustment mechanism, further improving the consistency of yarn tension and blending quality during blending.

[0038] It is worth mentioning that, see Figure 2 The tensioning wheel 44 has a first annular groove 45 on its outer periphery, and the first annular groove 45 is located in the middle of the outer periphery of the tensioning wheel 44. When the yarn is wound on the tensioning wheel 44, the first annular groove 45 can restrict the lateral displacement of the yarn, so that it is always in the center position of the tensioning wheel 44, preventing the yarn from slipping off or deviating from the tensioning wheel 44 during the tension adjustment process, and ensuring that the tensioning wheel 44 applies tension to the yarn accurately and effectively.

[0039] It is worth mentioning that, see Figure 1The outer periphery of the limiting roller 31 is provided with a plurality of second annular grooves 32, and the plurality of second annular grooves 32 are equally distributed on the outer periphery of the limiting roller 31. By embedding each yarn into an independent second annular groove 32, not only can multiple yarns be prevented from rubbing or tangling with each other on the limiting roller 31, but also the limiting effect of the annular groove can be used to ensure that each yarn maintains a fixed spacing and path when passing through the limiting roller 31.

[0040] It is worth mentioning that, see Figure 3 A pressure sensor 7 is fixedly installed at the middle of one end of the adjusting plate 48 near the spring 49. The end of the spring 49 near the pressure sensor 7 corresponds to the pressure sensor 7. After the signal is processed by the control processor in the prior art, the pressure sensor 7 is connected to an external display screen (not shown in the figure). When the adjusting screw 47 drives the adjusting plate 48 to compress the spring 49 to adjust the position of the tension wheel 44, the pressure sensor 7 collects the pressure value generated by the deformation of the spring 49 in real time. This data is processed by the control processor and displayed on the display screen. Thus, the independent pressure sensor 7 allows the operator to view the tension value of each yarn in real time, providing data support for precise control, ensuring that the tension is accurately constant within the process requirements, and avoiding yarn breakage or blended structure defects caused by uneven tension.
