Post production process of short fiber finished products

Abstract

The invention relates to a post-production process of short fiber finished products, the steps of which are: spinning, tow convergence, crimping, cutting and metering and packing; the invention improves the oil inlet of the oiling ring, sets a tail silk alarm processing device, Adopting methods such as tow amplitude modulation device, rotary spare cutting mechanism, and new adjustable packing and briquetting solves the main problems in the current production process of short fiber downstream melt spinning, and provides a stable product quality and a production process. Low failure rate, low production cost, and adjustable packing belt for post-production process of short fiber finished products.

Description

technical field [0001] The invention relates to a downstream production process of staple fiber products, belonging 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 pr...

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.
