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.

Embodiment 1

[0018] A process for keeping the freshness of reeling cocoons when the silk reeling machine is stopped, comprising the following steps:

[0019] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;

[0020] 2) mixing the glacial acetic acid with water to obtain an aqueous acetic acid solution with a concentration of 10% to 30% (V / V);

[0021] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, spray evenly on the remaining cocoons remaining in the silk reeling tank with the sprayer, and allow it to soak naturally for 15 minutes;

[0022] 4) Slowly add cold water at a temperature of 5°C at a flow rate of 500ml / min into the silk reeling tank until the silk reeling tank is full.

[0023] The deterioration and color change of reeled cocoons are divided into 3 grades: Grade 0: the cocoon body is completely white; Grade 1: slight yellowing; Grade 2: deep yellowing; Grade 3: extremely yellowing of;

[0024...

Embodiment 2

[0027] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;

[0028] 2) mixing the glacial acetic acid with water to obtain a 20% (V / V) acetic acid aqueous solution;

[0029] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, and evenly spray it on the remaining reeled cocoons remaining in the silk reeling tank with the sprayer, allowing it to soak naturally for 20 minutes;

[0030] 4) Slowly add cold water at a temperature of 10°C to the silk reeling tank at a flow rate of 1000ml / min until the silk reeling tank is full.

[0031] In this way, do not add water to the silk reeling soup, directly add glacial acetic acid with an equivalent concentration of 20% to the silk reeling soup, and directly add glacial acetic acid to the silk reeling soup to reach a concentration of 20%, as shown in figure 2 Shown, the deterioration index method of embodiment 2 is all lower than all the other two methods, has be...

Embodiment 3

[0033] 1) After the automatic silk reeling machine stops, drain the silk reeling soup in the silk reeling tank;

[0034] 2) mixing the glacial acetic acid with water to obtain a 30% (V / V) acetic acid aqueous solution;

[0035] 3) Put the aqueous acetic acid solution obtained in step 2) into a sprayer, spray evenly on the remaining cocoons remaining in the silk reeling tank with the sprayer, and allow it to soak naturally for 15 minutes;

[0036] 4) Slowly add cold water at a temperature of 15°C at a flow rate of 1500ml / min into the silk reeling tank until the silk reeling tank is full.

[0037] This is compared with the 3000ml / min flow rate filling, 20 ℃ silk reeling tank environment, 6000ml / min flow rate filling, 25 ℃ silk reeling tank environment, for example image 3 Shown, the deterioration index method of embodiment 3 is all lower than other two kinds of methods, and flow rate adds water speed too fast and can affect the gradual dilution and the dispersal of the acetic a...

Abstract

The invention provides a carry-over cocoon fresh-keeping technology used after automatic reeling machine stoppage. According to the technology, after automatic reeling machine stoppage, silk reeling water in a silk reeling groove is dried; glacial acetic acid and water are mixed to obtain an acetic acid aqueous solution; the obtained acetic acid aqueous solution is uniformly sprayed on the residual carry-over cocoon in the silk reeling groove by a sprayer, the residual carry-over cocoon is naturally soaked for 15-20 minutes; and cold water is slowly added in the silk reeling groove until the silk reeling groove is full. The technology does not require reel-up operation after stoppage, so that output is increased, consumption is reduced, quality fluctuation due to reel-up and cocoon feeding can be avoided, quality stabilization is ensured, long fresh-keeping time can be provided for the carry-over cocoon, and the carry-over cocoon cannot generate deterioration and corruption in 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 ...
