Description

Technical Field

[0001] This utility model relates to the field of polypropylene fiber technology, specifically to a polypropylene fiber blending modification device. Background Technology

[0002] Polypropylene (PP) fiber is a synthetic fiber made from polypropylene, and its commercial name in my country is polypropylene fiber. When modifying polypropylene fiber, low-viscosity polyoxymethylene (POM) is used for melt blending with PP, and the flow properties of the melt are adjusted by adding 1% to 3% cooling masterbatch.

[0003] According to a Chinese patent publication (CN215463974U), a mixing device for modified polypropylene production includes a mixing tank, a mixing mechanism, a material circulation mixing device, and a disassembly / assembly mechanism for assembling and disassembling the mixing mechanism. The material circulation mixing device includes material lifting devices symmetrically arranged on both sides of the mixing tank. Material circulation inlets and outlets are respectively located at the upper and lower ends of the outer walls on both sides of the mixing tank. A pusher device is also provided inside the mixing tank to push the material towards the material circulation outlet. This invention, by setting up the pusher device and the material lifting device, can circulate the pre-mixed material in the mixing tank to the upper end of the mixing tank via the feed circulation device and re-enter the mixing tank for further mixing, achieving a more uniform mixing of the materials. Simultaneously, by setting up the disassembly / assembly structure, the L-shaped limiting block moves outward from the edge of the second circular connecting plate as the turntable rotates in the opposite direction, achieving a convenient disassembly / assembly effect.

[0004] However, existing devices still have the following problems: materials easily settle at the bottom during stirring, leading to uneven mixing, reduced blending modification efficiency, and easy waste of materials. Therefore, a polypropylene fiber blending modification device is proposed. Utility Model Content

When the rotating plate 616 rotates, it causes the slide plate 618 to move up and down through the slide groove. The slide plate 618 drives the support rod 618 to rise and fall. The support rod 618 drives the support plate 601 to move back and forth on the slide rod 6112. The support plate 601 drives the first stirring plate 605 and the second stirring plate 607 to move up and down, thereby uniformly stirring and mixing the polyoxymethylene, cooling masterbatch and polypropylene in the production tank 1, so as to prepare blended modified high-performance polypropylene fibers with good spinnability and excellent performance.
