Description

Technical Field

[0001] This utility model relates to the technical field of yarn twisting and plying equipment, specifically to a yarn twisting and plying equipment. Background Technology

[0002] In the textile industry, yarn doubling and plying is a crucial process for improving yarn performance and meeting the production needs of different fabrics. Existing yarn doubling and plying equipment includes a centering mechanism to ensure centered yarn transport. This mechanism typically employs a pressure roller structure, using two symmetrically arranged rollers to clamp and guide the passing single yarns, ensuring that multiple yarns remain aligned before entering the twisting mechanism. This prevents quality issues such as uneven twist and strength fluctuations in the ply yarn caused by yarn misalignment. However, current centering mechanisms still rely on manual operation for adjusting the roller positions. Specifically, operators must adjust the relative distance between the two rollers by rotating knobs to accommodate single yarns of different thicknesses or correct deviations during yarn transport. This manual adjustment method is inefficient. During textile production, when switching between different yarn varieties and linear densities, operators must stop the machine and repeatedly adjust the positions of the rollers in the two centering mechanisms until the yarn achieves the desired centering effect. This process not only consumes a significant amount of manual time but also increases equipment downtime. Especially in small-batch, multi-variety production scenarios, frequent manual adjustments drastically reduce the effective operating time of the equipment, hindering overall production efficiency. Furthermore, manual adjustment cannot achieve synchronous adjustment of the two sets of centering mechanism pressure rollers, easily leading to uneven yarn stress and insufficient centering accuracy. Therefore, this invention provides a yarn doubling and plying device. Utility Model Content

[0003] The purpose of this invention is to provide a yarn twisting and plying device.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A yarn doubling and plying device includes: a base, on which a plurality of support seats are provided, and two support plates are spaced apart on the top of the support seats. Two mounting frames symmetrically arranged along the support seats are slidably provided on the support plates. An extension block is provided at the bottom of the mounting frame. The extension block extends from the gap between the two support plates to below the support plates and is threadedly engaged with a first lead screw rotatably mounted on the support base. The surface of the first lead screw has two sets of threads, which are threadedly engaged with the two extension blocks respectively. A rotating handle is provided at one end of the first lead screw. Two pressure rollers are rotatably arranged inside the mounting frame. One pressure roller has a convex ring, and the other pressure roller has a concave ring that matches the convex ring. A connecting block is provided on the top of the pressure roller. The connecting block extends from the opening in the top of the mounting frame to the top of the mounting frame and is threadedly engaged with a second lead screw rotatably arranged above the mounting frame. The surface of the second lead screw has two sets of opposite threads, which are threadedly engaged with the two connecting blocks respectively. The support base is provided with a mounting plate, and a shaft is rotatably mounted on the mounting plate. The shaft extends to both sides and is inserted into the center of the second lead screw, and is keyed to the second lead screw. A first transmission wheel is sleeved on the shaft, and the first transmission wheel is connected to the adjacent first transmission wheel through a first transmission belt. The first transmission belt is driven by a drive device.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme, the support plate is provided with fixing plates at both ends; the first lead screw is connected to the fixing plates at both ends; and the shaft is connected to the fixing plates at both ends.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme, two side plates are provided at both ends of the top of the mounting frame, and the two ends of the second lead screw are connected to the side plates.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme, there are two mounting plates, and the two mounting plates are spaced apart to form an installation space between the two mounting plates; the first transmission wheel and the first transmission belt are disposed within the installation space.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme, a second transmission wheel that cooperates with the first transmission belt is provided in the installation space, and a third transmission wheel that is coaxial with and rotates synchronously with the second transmission wheel is provided on one side of the second transmission wheel. The third transmission wheel is connected to the drive device provided on the base through the second transmission belt.

[0009] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model uses a driving device to drive the first transmission wheel to rotate, which in turn drives the shaft to rotate. The shaft rotation drives the second lead screw to rotate, and the second lead screw drives the two connecting plates to move synchronously in opposite directions, thus achieving automatic adjustment of the distance between the two pressure rollers. This is more convenient than manual adjustment and ensures synchronous adjustment of each group of pressure rollers. Simultaneously, the distance between the two mounting frames can be adjusted via the first lead screw to adapt to different usage requirements. Attached Figure Description

[0016] like Figure 1 and Figure 2 As shown, a yarn doubling and plying device includes: a base 1, a plurality of support seats 2 are provided on the base 1, two support plates 3 are provided at intervals on the top of the support seats 2, and two mounting frames 4 slidably arranged on the support plates 3 along the support seats 2 symmetrically.

[0017] The bottom of the mounting frame 4 is provided with a downwardly protruding extension block 5. The extension block 5 extends from the gap between the two support plates 3 to below the support plates 3, and is threadedly engaged with a first lead screw 6, which is rotatably mounted on the support base 2 and located below the support plates 3. The surface of the first lead screw 6 has two sets of threads, which are threadedly engaged with the two extension blocks 5 respectively, so as to drive the two mounting frames 4 to move synchronously in opposite directions.

[0018] like Figure 3 and Figure 4 As shown, the support plate 3 has fixing plates 18 at both ends, which can act as limiting components to restrict the movement of the mounting frame 4. The first lead screw 6 is connected to the fixing plates 18 at both ends. At the same time, a rotating handle 7 is provided at one end of the first lead screw 6, which is located outside the fixing plate 18, so that the operator can rotate the first lead screw 6.

[0019] Two pressure rollers 8 are rotatably mounted inside the mounting frame 4, and the two pressure rollers 8 are symmetrically arranged along the center line of the mounting frame 4. One pressure roller 8 is provided with a convex ring 9, and the other pressure roller 8 is provided with a concave ring 10 that matches the convex ring 9. The yarn passes between the convex ring 9 and the concave ring 10.

[0020] A connecting block 11 is provided on the top of the pressure roller 8. The connecting block 11 extends from the opening in the top of the mounting frame 4 to the top of the mounting frame 4 and is threadedly engaged with the second lead screw 12, which is rotatably mounted on the top of the mounting frame 4. The surface of the second lead screw 12 has two sets of opposite threads, which are threadedly engaged with the two connecting blocks 11 respectively, so as to drive the two connecting blocks 11 to move synchronously in opposite directions, thereby realizing the adjustment of the distance between the two pressure rollers 8.

[0021] The top of the mounting frame 4 has two side plates 19, and the two ends of the second lead screw 12 are connected to the side plates 19.

[0022] A mounting plate 13 is provided on the support base 2, and a shaft 14 is rotatably mounted on the mounting plate 13.

The mounting block 13 serves as a movable limiting plate at the other end of the mounting frame 4.

[0023] The second lead screw 12 is hollow, and the shaft 14 is inserted inside the second lead screw 12 and keyed to it. This allows it to transmit torque without affecting the axial movement of the second lead screw 12 relative to the shaft 14. When the mounting frame 4 moves, it can cause the second lead screw 12 to move relative to the shaft 14. Both ends of the shaft 14 are connected to two fixing plates 18 to improve its stability.

[0024] A first transmission wheel 15 is sleeved on the shaft 14. The first transmission wheel 15 is connected to the adjacent first transmission wheel 15 through the first transmission belt 16 to ensure that the shafts 14 of each group of mechanisms rotate synchronously, thereby ensuring that each group of pressure rollers 8 rotates synchronously.

[0025] The first transmission belt 16 is driven by the drive device 17. Specifically, the first transmission wheel 15 and the first transmission belt 16 are arranged in the installation space. The installation space is also provided with a second transmission wheel 20 that cooperates with the first transmission belt 16. A third transmission wheel 21 that is coaxial with and rotates synchronously with the second transmission wheel 20 is arranged on one side of the second transmission wheel 20.

[0026] The drive unit 17 is a motor, which drives the third drive wheel 21 to rotate via the second drive belt 22. The third drive wheel 21 drives the second drive wheel 20 to rotate. The second drive wheel 20 drives each first drive wheel 15 to rotate synchronously via the first drive belt 16. The first drive wheels 15 drive each shaft 14 to rotate synchronously. Among them, each drive wheel is a sprocket, and each drive belt is a chain.
