Description

Technical Field

[0001] This application relates to the technical field of unwinding devices, and particularly to an unwinding device for yarns. Background Art

[0002] In the textile industry, the unwinding of yarns is a crucial step, and its quality directly affects the subsequent production efficiency and product quality.

[0003] In the existing yarn unwinding devices during the unwinding process, due to the lack of tensioning and deviation rectifying structures, the yarn is not only prone to slackening but also to deviation, which may not only cause the yarn to break during processing but also affect the quality of the final product. Summary of the Utility Model

[0004] The problem to be solved by this application is that the existing yarn unwinding devices lack tensioning and deviation rectifying structures, resulting in the yarn being prone to slackening and deviation.

[0005] To solve the above technical problems, this application provides an unwinding device for yarns, which includes a frame for basic support. A roller for unwinding yarns is horizontally arranged on one side of the frame. A tensioning support assembly for supporting and adjusting the tension is arranged on the upper part of the frame. A deviation rectifying assembly for supporting and preventing deviation of the yarn is also arranged on the upper part of the frame. A clamping assembly for clamping the roller is arranged at one end of the tensioning support assembly, and a driving assembly for driving the roller to rotate is arranged at the other end of the tensioning support assembly.

[0006] Since the unwinding device of this application is designed with a tensioning support assembly, a deviation rectifying assembly, a clamping assembly, and a driving assembly, it can not only achieve the tension adjustment operation of the yarn through the tensioning support assembly, but also achieve the deviation rectifying and limiting operation of the yarn through the deviation rectifying assembly, and can also achieve the clamping and driving operations of the roller through the clamping assembly and the driving assembly, solving the problem that the existing yarn unwinding devices lack tensioning and deviation rectifying structures, resulting in the yarn being prone to slackening and deviation.

[0016] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment

[0017] The present application relates to a yarn unwinding device, as Figure 1-8 shown. The unwinding device includes a frame 2 for basic support. A roller 5 for unwinding yarn is horizontally arranged on one side of the frame 2. In order to be able to adjust the tension of the yarn when the roller 5 unwinds, therefore, a tight support assembly 3 that can support and adjust the tension is arranged on the upper part of the frame 2. And a deviation rectifying assembly 1 that can support and prevent deviation of the yarn is also arranged on the upper part of the frame 2. In order to facilitate the loading and unloading operations of the roller 5, therefore, a clamping assembly 6 for clamping the roller 5 is arranged at one end of the tight support assembly 3, and a driving assembly 4 for driving the roller 5 to rotate is arranged at the other end of the tight support assembly 3.

[0018] The tight support assembly 3 includes a bracket 16 and a first hydraulic cylinder 15. The bracket 16 is integrally in a U-shaped structure. The two sides of the bracket 16 are connected to the frame 2 through bearing seats. And first hydraulic cylinders 15 for controlling the lifting operation of the bracket 16 are symmetrically arranged on the upper part of the frame 2. Thus, by means of the traction operation of the first hydraulic cylinder 15, the bracket 16 can be driven to rotate in space around the frame 2, so that the roller 5 on the upper part of the bracket 16 can perform appropriate traction and stretching operations on the yarn, so that the yarn can maintain a stable tension state.

[0019] The deviation rectifying assembly 1 includes a roller frame 9, pinch rollers 7, and supporting rollers 8. The roller frame 9 is arranged at one end of the upper part of the frame 2. On the upper part of the roller frame 9, pinch rollers 7 are symmetrically arranged for performing a lateral position-limiting and deviation rectifying operation on the yarn, and the positions of the pinch rollers 7 are adjustable. Supporting rollers 8 for supporting the lower part of the yarn longitudinally are also arranged on both sides of the roller frame 9. Thus, by means of the combined action of the pinch rollers 7 and the supporting rollers 8, the yarn can be effectively subjected to lateral and longitudinal position-limiting operations.

[0020] The clamping assembly 6 includes a second hydraulic cylinder 12, a connecting plate 13, and a clamping shaft 14. The second hydraulic cylinder 12 is arranged at one end of the bracket 16. The clamping shaft 14 is arranged on the upper part of the bracket 16 through a slidable bearing seat and is coaxially arranged with the roller 5. In order to be able to drive the clamping shaft 14 to perform a convenient clamping operation on the roller 5, therefore, a connecting plate 13 connected to the second hydraulic cylinder 12 and the clamping shaft 14 respectively is arranged inside the bracket 16. Thus, the second hydraulic cylinder 12 drives the connecting plate 13 and then drives the clamping shaft 14 to perform telescopic clamping operations along the axis direction of the roller 5.

[0021] The driving assembly 4 includes a motor 10 and a shaft rod 11. The shaft rod 11 is arranged at one end of the upper part of the bracket 16 and is connected to it through a bearing seat. And a motor 10 for driving the shaft rod 11 to operate is arranged outside the bracket 16. The other end of the shaft rod 11 is connected to the roller 5, and then drives the roller 5 to rotate.

[0022] During use, by connecting the roller 5 to the shaft rod 11, then the second hydraulic cylinder 12 drives the connecting plate 13 and then drives the clamping shaft 14 to perform a clamping and supporting operation on the other end of the roller 5. Immediately afterwards, the motor 10 can be used to drive the shaft rod 11 to drive the roller 5 to rotate on the upper part of the bracket 16. The yarn released by the roller 5 is subjected to a position deviation rectifying operation through the support of the pinch rollers 7 and the supporting rollers 8 on the upper part of the frame 2. And the first hydraulic cylinder 15 controls the bracket 16 to swing around the frame 2 in a spatial angle, so that the spatial position of the roller 5 changes synchronously, thereby enabling the yarn released by the roller 5 to be effectively tensioned.
