Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber production technology, specifically relating to a high-efficiency chemical fiber pre-spinning production line. Background Technology

[0002] With the development of the chemical fiber industry, the requirements for production efficiency and product quality of chemical fiber products are becoming increasingly stringent. Traditional chemical fiber pre-spinning production lines typically include multiple stages such as raw material conveying, pretreatment, forming, cutting, and collection. To improve production efficiency and reduce costs, high automation and intelligence of production lines have become key trends in industry development. Most existing chemical fiber cutting machines are driven by motors, achieving the cutting action through eccentric blocks and linkage mechanisms. However, due to structural design and cutting mechanism design, they often suffer from problems such as low cutting efficiency, unstable cutting quality, and difficult maintenance.

[0003] Existing synthetic fiber cutting machines suffer from insufficient design smoothness and reliability, often resulting in slow cutting speeds that fail to meet the demands of high-efficiency production, further impacting cutting efficiency. In existing technologies, the inadequate stability and precision of the blade holder lead to inaccurate product dimensions and even uneven cutting during the cutting process, thus affecting product quality. Furthermore, the complex design of the synthetic fiber cutter and blade holder in existing cutting machines makes replacement and maintenance cumbersome, resulting in prolonged maintenance time, increased downtime, reduced production continuity and flexibility, and an inability to quickly adapt to different production needs.

[0004] In view of this, we propose a high-efficiency pre-spinning production line for chemical fibers. Utility Model Content

The fiber cutter is fixed to the transverse block by bolts passing through the straight slots. The insertion slots, straight slots, and bolts on the transverse block facilitate quick installation and fixation of the fiber cutter, improving production efficiency and reducing maintenance time.

[0014] Preferably, the adjusting plate is fixed to the front side of the discharge plate with screws, and the discharge hole B is connected to the discharge hole A.

[0015] Preferably, the fiber cutter is guided and lifted along the front side of the adjustment plate to cut the fiber products exiting from outlet holes A and B. Cutting close to the adjustment plate improves cutting accuracy, reduces raw material waste, and enhances product quality.

[0016] Preferably, the guide frame consists of two guide rails with V-grooves fixed on the left and right sides of the frame of the chemical fiber cutting machine, and two vertical guide blocks slide up and down along the guide rails with V-grooves.

[0018] Preferably, the frame is fixed with an inclined feeding plate that guides the cut chemical fiber products to the inclined discharge conveyor belt.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This high-efficiency pre-spinning production line for synthetic fibers features a high-speed cutting mechanism in its cutting device. Driven by a motor, eccentric block, and connecting rod, the mechanism achieves lifting motion, working in conjunction with the synthetic fiber cutter to cut the formed product. The cutter holder design ensures the stability and accuracy of the cutter, while the use of a guide frame improves the smoothness and reliability of the cutting mechanism's movement. The design of the cutter holder and guide frame ensures cutting accuracy, reduces product dimensional deviations, and improves product quality.
