Description

Technical Field

[0001] The utility model relates to the technical field of draw frames, in particular to a cotton draw frame with good forming effect. Background Technique

[0002] The function of the draw frame is to improve the internal structure of the sliver, thereby improving its long-section evenness, reducing the weight unevenness rate at the same time, straightening and parallelizing the fibers in the sliver, reducing the hooks, making the fineness meet the requirements, and mixing different types or qualities of raw materials evenly to reach the specified mixing ratio. Draw frames are divided into two categories: roller drafting draw frames and gill boxes according to the form of the drafting mechanism.

[0003] Chinese patent with the authorization announcement number CN218026506U discloses a cotton draw frame with good forming effect, including a base, on the top of the base is provided a draw frame body, and on the top of the base is provided a support column located on the right side of the draw frame body. For this cotton draw frame with good forming effect, by setting a vertical plate and a limit ring, the sliver passes through the limit ring and then is connected to the draw frame body through a feeding roller. Since the limit ring is close to the sliver bucket, the limiting and fixing effect on the sliver is good and there will be no deviation. When the sliver is being drawn, it is not easy to cause poor drawing effect due to unstable fixing. By setting a threaded rod, rotating the threaded rod drives the threaded plate to move backward. Through the cooperation of the threaded plate and the connecting rod, the slider can cooperate with the compression spring to drive two clamping blocks to move relatively and disengage from the fixed block, thus achieving the purpose of facilitating the disassembly and assembly of the feeding roller, greatly improving the practicability of the device.

[0004] However, the above technical solution has the following defects: In the above-mentioned cotton draw frame with good forming effect, the position of the limit ring is fixed, making it inconvenient to adjust the positions of multiple slivers when they are incorporated; after long-term use, impurities or short yarns will be wound on the feeding roller, affecting the forming effect of the draw frame and being inconvenient to use.
