Short fiber finished product subsequent production line

Abstract

The invention relates to a short fiber finished product subsequent production line. The short fiber finished product subsequent production line comprises a spinning machine (9), an oiling ring (10), ayarn storage box (11), a yarn guide frame (12), a tail yarn alarm device (13), a crimping machine (14), a yarn bundle breadth adjusting device (15), a yarn cutting-off machine (16) and a packing machine (17), wherein the spinning machine (9), the oiling ring (10), the yarn storage box (11), the yarn guide frame (12), the crimping machine (14), the yarn cutting-off machine (16) and the packing machine (17) are sequentially arranged. The short fiber finished product subsequent production line is stable in product quality, low in failure rate in the production process, low in production cost andadjustable in packing belt.

Description

technical field [0001] The invention relates to a downstream production line of staple fiber products, which belongs to the technical field of polyester staple fiber production. Background technique [0002] The production process of polyester staple fiber includes polyester melt synthesis and melt spinning. The existing melt spinning production process mainly has the following problems: [0003] 1. Spinning oiling problem: The oil film is unevenly distributed in the oiling ring, resulting in uneven quality of the spun silk, more weak yarns, high unevenness, and easy breakage and fluffing in the subsequent production process. problems, which seriously affect the production rhythm and product quality; [0004] 2. The problem of tail silk processing: in the process of spinning and trimming, the tow will be stiff, and there will be relatively hard agglomerates at the end of the whole tow. These stiffness or agglomerates are collectively called tail silk. When the continuous p...

Problems solved by technology

[0003] 1. Spinning oiling problem: The oil film is unevenly distributed in the oiling ring, resulting in uneven quality of the spun silk, more weak yarns, high unevenness, and easy breakage and fluffing in the subsequent production process. problems, which seriously affect the production rhythm and product quality;

[0004] 2. The problem of tail silk processing: in the process of spinning and trimming, the tow will be stiff, and there will be relatively hard agglomerates at the end of the whole tow. These stiffness or agglomerates are collectively called tail silk. When the continuous production reaches the tail, due to the lack of timely and effective alarm processing method, the hard block of tail silk enters the subsequent production equipment, causing equipment failure and shutdown; and once the tail silk is mixed into the finished product package, the product quality will decline;

[0005] 3. The problem of uneven wire width of the crimping machine: when the tow enters the crimping machine for crimping, due to the fluctuation of the width of the tow, the thickness of the tow on both sides of the crimping roller is uneven, some are too thick and some are too thin, resulting in the crimping process If it is not normal, it is easy to cause the crimping machine to fail and stop;

[0006] 4. Spinning and cutting problem: when changing the blade of the cutting machine, it needs to be shut down, which affects the production rhythm, and the alarm cannot be handled when the blade breaks abnormally;

[0007] 5. Handling of abnormal packages: Abnormal packages caused by reasons such as unqualified weight and improper packaging during the production process need to wait for the production gap before processing. The processing process is relatively complicated. If the processing is not timely and involves many When there are abnormal packages of different varieties of products, it is also easy to cause quality accidents such as mixed varieties;

[0008] 6. Packing problem: only 6 packing tapes can be fixed, and the packing position cannot be adjusted. It cannot be applied to the situation that different varieties require different packing tape quantities and different packing positions. There is also the problem of oil pollution of the packing machine during the packing process.
