A fresh-keeping process for reeling leftover cocoons when the automatic silk reeling machine stops

Abstract

The invention provides a fresh-keeping process for reeling leftover cocoons when the silk reeling machine stops. After the automatic silk reeling machine stops, the silk reeling soup in the silk reeling tank is drained; glacial acetic acid is mixed with water to obtain an aqueous solution of acetic acid; Spray the obtained acetic acid aqueous solution evenly on the remaining reeled cocoons in the reeling tank with a sprayer, and allow it to soak naturally for 15-20 minutes; slowly add cold water to the reeling tank until the reeling tank is full. The technical process can effectively eliminate the need for parallel operation after parking, so the output can be increased, the consumption can be reduced, the quality fluctuation caused by parallel thread and upper thread can be avoided, the quality can be guaranteed, and the leftover cocoons can have a longer period of time. The fresh-keeping time can prevent the leftover cocoons from going bad and corrupt within 60 hours.

Description

technical field [0001] The invention relates to a fresh-keeping technology for cocoons in cocoon making silk, in particular to a fresh-keeping technology for leftover cocoons after an automatic silk reeling machine stops. Background technique [0002] The silk reeling machine is a silk reeling method that uses mechanical movement to replace the manual operations of vertical reeling (such as threading, threading, adding threads, removing pupae and picking up thread cocoons, etc.), and automatically controls the size of raw silk. This reeling method can expand the monitoring capacity, speed up the coiling speed (generally up to 70-115 m / min), and improve labor productivity. Automatic reeling has two types of silk reeling with fixed grain sensing and fixed fiber sensing. Since the silk reeling machine has the characteristics of continuous work, and the cocoons soaked in the silk reeling soup for a long time are easily deteriorated and corrupted at high temperature, the cocoons ...

AI Technical Summary

Problems solved by technology

Since the silk reeling machine has the characteristics of continuous work, and the cocoons soaked in the silk reeling soup for a long time are easily deteriorated and corrupted at high temperature, the cocoons in the silk reeling soup need to be reeled in time. Therefore, when the workshop is off work, Or when the silk reeling machine is overhauled, it is necessary to stop the silk reeling machine and stop the reeling work. Therefore, the remaining cocoons left in the reeling tank of the silk reeling machine are called reeling cocoons, especially in summer and autumn, when the temperature is too high , The leftover cocoons generally begin to undergo qualitative change and corruption after about 10 hours. The color of the spoiled cocoons will turn yellow, and it will seriously affect the unwinding rate and silk yield of the leftover cocoons, resulting in defective filaments or increasing the probability of falling threads. Therefore, in the traditional silk reeling process, especially after the silk reeling car is parked after work on weekends, the parallel threading operation needs to be carried out immediately, and the parallel threading operation is usually started one hour before the parking time. It usually takes 40 minutes to merge five threads or ten threads together, and the thread number gradually decreases during the threading time, and the time spent in threading is equivalent to the normal production speed to produce 2 packs of cocoons less; start again on Monday morning thread, regenerate thread time about 50 minutes

The time it takes to re-thread is equivalent to less production of about 3 packs of cocoons. Therefore, long-term operation will not only increase labor costs, but also cause a decline in productivity and work efficiency.
