Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene monofilament production technology, specifically to a raw material quantitative addition device for polypropylene monofilament production. Background Technology
[0002] Polypropylene monofilament refers to a single long filament produced from a single spinneret, typically with a diameter of 0.2 mm or 0.25 mm. It is a chemical fiber, specifically polypropylene fiber. Using solution dyeing technology and melt spinning, solution-dyed high-strength polypropylene monofilament has been prepared, solving the problems of difficulty in dyeing polypropylene and the need for subsequent dyeing treatment.
[0003] Currently, in the production of polypropylene monofilament, masterbatch and polypropylene resin are typically added manually to the chemical equipment. However, this method not only increases the workload for workers but also results in inaccurate dosages, potentially affecting the quality of subsequent chemicals and failing to achieve precise quantitative addition, thus leading to poor-quality polypropylene monofilament. Therefore, this paper proposes a quantitative raw material addition device for polypropylene monofilament production. Summary of the Invention

[0028] Four connecting brackets 2 are fixedly connected to the surface of production tank 1;

The bottom surface of the tube 608 is slidably connected to the top surface of the production tank 1. The tube 608 is located above the feed tube 4. Through the addition component 60, the first rotating rod 602 drives the stirring plate 603 and the support plate 604 to rotate, which in turn drives the addition tank 605 and the addition tube 608 to rotate. This allows the raw materials in the addition tank 605 to be evenly added to different feed tubes 4 through the addition tube 608, thus achieving quantitative and dispersed addition of raw materials to the production tank 1. This avoids the problem of raw materials accumulating in the same position in the production tank 1, which would lead to a long mixing time.

A first connecting rod 613 and a second connecting rod 615 are fixedly connected to the surface of the second rotating rod 612. A first scraper 614 and a second scraper 616 are fixedly connected to the end faces of the first connecting rod 613 and the second connecting rod 615, respectively. The sides of the first scraper 614 and the second scraper 616 are slidably connected to the inner side of the addition tank 605. A second motor 611 is fixedly connected to the top surface of the addition tank 605. The bottom end face of the output rod of the second motor 611 extends through the top surface of the addition tank 605 into the addition tank 605. The bottom end face of the output rod of the second motor 611 is fixedly connected to the top end face of the second rotating rod 612. Through the cleaning assembly 61, the second rotating rod 612 drives the first connecting rod 613 and the second connecting rod 615 to rotate, thereby rotating the raw materials in the addition tank 605 and driving the first scraper 614 and the second scraper 616 to rotate and clean the raw materials on the inner wall of the addition tank 605, thus avoiding waste of resources.
[0039] In use, open the pipe cap 607 and add the color masterbatch raw material and polypropylene resin raw material into the addition tank 605 in batches through the feeding pipe 606. Then, cover the feeding pipe 607 with the pipe cap 607. Turn on the first motor 601. The output rod of the first motor 601 drives the connected first rotating rod 602 to rotate. The first rotating rod 602 drives the support plate 604 to rotate, causing the support plate 604 to drive the addition tank 605 and the support rod 609 to rotate. The support rod 609 drives the roller 6010 to rotate above the production tank 1. 5. The addition pipe 608 is rotated, opening the second valve. The color masterbatch raw material / polypropylene resin raw material in the addition tank 605 is discharged into the feed pipe 4 through the addition pipe 608. The first rotating rod 602 drives the connecting plate 6012 to rotate, causing the annular baffle 6011 to rotate on the production tank 1, thereby quantitatively and evenly dispersing the color masterbatch raw material / polypropylene resin raw material into the production tank 1. When the first rotating rod 602 rotates, it drives the stirring plate 603 to rotate, realizing the mixing and stirring of the color masterbatch raw material and polypropylene resin raw material in the production tank 1.
[0040] By selecting the grade of polypropylene masterbatch and adjusting the amount of masterbatch added within the range of 1% to 3%, polypropylene colored yarn with strong coloring ability and uniform dyeing can be obtained.
[0041] Add 1% to 3% color masterbatch and 97% to 99% polypropylene resin, adjust the addition ratio between the two, and regulate the temperature of different sections of the screw to obtain polypropylene color fiber melt with good flow properties and uniform color.
[0042] Based on the obtained optimal formula, the spinning temperature was controlled at 240–270℃, the water cooling temperature at 15–20℃, the drawing temperature at 90–150℃, and the setting temperature at 140–160℃, and these parameters were optimized. The influence of spinning parameters on the properties of polypropylene colored yarn was studied, and a stable solution-dyed high-strength polypropylene monofilament was obtained.
[0043] When the second motor 611 is turned on, the output rod of the second motor 611 drives the connected second rotating rod 612 to rotate, which in turn causes the first connecting rod 613 and the second connecting rod 615 to rotate, thereby driving the first scraper 614 and the second scraper 616 to rotate. The first scraper 614 and the second scraper 616 scrape off the color masterbatch raw material / polypropylene resin raw material adhering to the inner wall of the addition tank 608, thereby reducing the waste of raw materials.
