Description

Technical Field

[0001] This utility model belongs to the field of drafting mechanisms, specifically, it relates to a drafting mechanism for a ring spinning machine. Background Technology

[0002] The existing technology of drafting involves stretching and thinning the combed sliver, gradually straightening the fibers, eliminating hooks, and gradually bringing the sliver to a predetermined thickness.

[0003] Chinese Patent Application No. CN202420104322.X discloses a drafting mechanism for a semi-worsted roving machine, including a roller, a chuck, and a support shaft. The roller has four drafting zones and four annular grooves evenly distributed on its surface. Two annular grooves are evenly distributed between two drafting zones, and the other two are evenly distributed between the remaining two drafting zones. The support shaft is inserted into the chuck, and a pulley is rotatably mounted at each end of the support shaft. Two limiters are evenly fixedly mounted on the support shaft. The two limiters are positioned between two pulleys, locked in their corresponding annular grooves, and rotatably connected to the grooves. This overall design allows for quick positioning of the pulleys and rollers after roller position adjustment via the limiters, making adjustment more convenient and flexible. Simultaneously, it ensures stability between the roller and pulleys during roving drafting, preventing displacement between them.

[0004] However, in actual use, the aforementioned devices typically connect the limit rollers to the rollers via a fixed connection. While this design provides a degree of stability, it has some shortcomings in practical operation. Furthermore, the fixed connection structure is cumbersome to install and maintain, increasing the workload of operators. The structure mentioned in the comparative document, which facilitates the connection of the limit rollers, solves these problems to some extent, but still suffers from inconvenient adjustment and slow response speed. Especially on high-speed production lines, the rapid response and precise adjustment of the limit rollers are of paramount importance.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0009] The mixing component includes a roller, and the roller has a traction zone evenly distributed on its outer side;

[0010] The adjusting component includes a chuck positioned above the roller. A spring box is located at the bottom of the chuck, and a rotating wheel is located at the bottom of the spring box. Leather wheels are located on both outer sides of the chuck. A moving block is located on the outer circumference of the rotating wheel. A sliding block is located at the bottom of the chuck, and a supporting vertical rod is located at the bottom of the moving block. A limit wheel is located on the outer side of the supporting vertical rod.

[0011] Optionally, a threaded groove is provided on one side of the roller, and wheel grooves are provided on both sides of the traction zone. The function of the threaded groove is to facilitate threaded connection with external objects.

[0012] Optionally, the top two sides of the clamp are provided with supporting vertical plates, and an extension head is provided between the two supporting vertical plates.

[0013] Optionally, the mainspring box is equipped with a mainspring spring inside, which can conveniently control the rotation of the rotating wheel.

[0015] Optionally, the movable slider has a movable hole inside, the movable slider is slidably connected to the movable block, and the movable block has a bottom auxiliary rod.

[0016] Optionally, an adjusting base plate is provided at the bottom of the supporting vertical rod, and a supporting rotating rod connected to the adjusting base plate is provided on one side of the limiting wheel, and the supporting rotating rod is rotatably connected to the limiting wheel.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] The elastic design of the spring box in this invention allows the limiting rollers to respond quickly to changes in the actual tension of the fiber sliver and adjust their position in real time. This ensures that the tension of the fiber sliver is always at its optimal level during the drafting process, improving the quality and stability of the yarn. The elastic adjustment of the spring box makes it easier for operators to install and adjust the limiting rollers, reducing complex mechanical adjustment steps, lowering operational difficulty and maintenance costs. The elastic design of the spring box also allows the drafting mechanism to better adapt to different types and thicknesses of fiber slivers, meeting various production needs and improving the versatility and flexibility of the equipment.

[0028] Please see Figure 1-3As shown, this embodiment provides a drafting mechanism for a ring spinning machine, including a stirring component 1 and an adjusting component 2;

[0029] The mixing component 1 includes a roller 101, and a traction zone 102 is uniformly arranged on the outside of the roller 101;

[0030] The adjusting component 2 includes a chuck 201, which is positioned above the roller 101. A spring box 202 is located at the bottom of the chuck 201, and a rotating wheel 204 is located at the bottom of the spring box 202. Both outer sides of the chuck 201 are provided with leather wheels 203. A moving block 205 is located on the outer circumference of the rotating wheel 204.

A limit wheel 208 is located on the outer side of the supporting vertical rod 207.

[0031] The elastic design of the spring box 202 in this invention allows the limiting wheel 208 to respond quickly to changes in the actual tension of the fiber sliver and adjust its position in real time. This ensures that the tension of the fiber sliver is always at its optimal level during the drafting process, improving the quality and stability of the yarn. The elastic adjustment of the spring box 202 makes it easier for operators to install and adjust the limiting wheel 208, reducing complex mechanical adjustment steps, lowering operational difficulty and maintenance costs. The elastic design of the spring box 202 allows the drafting mechanism to better adapt to different types and thicknesses of fiber slivers, meeting various production needs and improving the versatility and flexibility of the equipment. The elastic adjustment of the spring box 202 effectively reduces hard collisions between the limiting wheel 208 and the roller 101, reducing wear, extending the service life of the equipment, and reducing downtime and maintenance costs caused by equipment failure.

[0032] In terms of usage, the roller 101, in conjunction with the limiting wheel 208, facilitates transmission. The spring box 202 at the bottom of the chuck 201 allows the rotating wheel 204 to have elasticity, thus facilitating the adjustment and control of object clamping. The connection between the movable slider 206 and the adjusting base plate 2071 facilitates the adjustment and control of the connection of the limiting wheel 208, ensuring a stable connection in the future.

[0033] In this embodiment, a threaded groove is provided on one side of the roller roller 101, and wheel grooves 1021 are provided on both sides of the traction area 102. The threaded groove is used to facilitate threaded connection with external objects, and the wheel grooves 1021 are used to facilitate connection with the limiting wheel 208, thereby facilitating transmission connection.

[0034] In this embodiment, support vertical plates are provided on both sides of the top of the clamp 201, and an extension head 2011 is provided between the two support vertical plates. The extension head 2011 can be used to support the object and facilitate the adjustment of the object's connection.

[0035] In this embodiment, a spring is provided inside the spring box 202. The spring can easily control the rotation of the rotating wheel 204, thereby driving the adjustment rotation of the adjusting rotating wheel 204, which facilitates the control of the rotation of the rotating wheel 204.

[0036] In this embodiment, both the outer surface of the rotating wheel 204 and the outer surface of the moving block 205 are provided with moving holes. The rotating wheel 204 meshes with the moving block 205, thereby enabling convenient adjustment of the moving block 205 and realizing the telescopic movement of the moving block 205.

[0037] In this embodiment, the movable slider 206 has a movable hole inside, the movable slider 206 is slidably connected to the movable block 205, and the bottom auxiliary rod 2051 of the movable block 205 realizes the adjustment of the position of the movable block 205.

[0038] In this embodiment, an adjusting base plate 2071 is provided at the bottom of the supporting vertical rod 207, and a supporting rotating rod 2081 connected to the adjusting base plate 2071 is provided on one side of the limiting wheel 208. The supporting rotating rod 2081 is rotatably connected to the limiting wheel 208, thereby driving and controlling the rotation of the limiting wheel 208.

[0039] In summary, the prior art has already described the structure that allows for easy connection of the limiting wheel 208. This application improves upon this by providing a spring box 202 at the bottom of the chuck 201. The elasticity of the spring box 202 allows for easy adjustment of the movement of the moving block 205, thereby facilitating the elastic connection of the limiting wheels 208 on both sides to the roller roller 101, making it more convenient to use.
