Pre-treatment equipment – silk fabric scouring equipment – star frame scouring machine

The star frame scouring machine consists of a star frame, a scouring barrel and a rolling machine. It can be refined as well as colored, and avoids defects such as hanging loop marks, gray wounds and wrinkle marks when being refined in a hanging trough.
(1) Star frame: The star frame is mainly composed of lifting rings, flat spiral disk assembly, frame, spokes, needle plate and crochet hook, etc., as shown in Figure 10-5.





The spoke 5 is equipped with a needle plate frame 6 and a blocking plate 10. The needle plate frame is embedded with crochet hooks 8 with a spacing of 10mm. A toothed block is welded on the needle plate frame, and a flat surface is embedded in the slot of the toothed block. Spiral plate, the longitudinal movement of the needle plate frame can be achieved by rotating the plane spiral. The retaining bar mechanism is installed on one side of each spoke of the frame to prevent the fabric from falling off the crochet hook during refining. After refining, the retaining bar can use the flat spiral mechanism to completely separate the fabric from the crochet hook. The blocking mechanism is composed of a blocking plate 10 and a U-shaped blocking bar 9. The number of blocking bars is one more than the crochet hook. Long grooves are opened at both ends of the blocking board, which are put on pulleys mounted on the spokes of the wheel, so that the blocking bars The components can move radially relative to each other along the spokes. A clutch positioner 4 is installed between the upper end of the baffle plate and the upper end of the needle plate frame, which can be closed or opened to control each needle plate assembly and the baffle assembly to move together along the spokes or separately.
When the fabric is put on the shelf, the needle plate frame is at the large hook diameter position, the positioning clutch is turned on, the blocking bar is in a locked state, and the second blocking bar is aligned with the first crochet needle bar, as shown in Figure 10-6(a) ) shown. At this time, hang the fabric on the crochet hook layer by layer from the inside to the outside. After hooking is completed, loosen the locking screw that fixes the barrier plate, move the barrier plate inward 5mm, close the clutch positioner, and now the barrier Located at 1/3 of the horizontal tip of the crochet hook, the stopper is “blocked” by the raw silk hooked on the needle, which effectively prevents the raw silk from falling off the crochet hook during the refining process, as shown in Figure 10-6(b).
During scouring, the plane spiral assembly is rotated to move the needle plate inward or outward to adapt to the shrinkage and expansion of the fabric. At this time, since the positioning clutch is closed, the stop bar moves synchronously with the needle plate. After refining, lock the bar plate, separate the positioning clutch, and rotate the plane spiral assembly to move the needle plate inwards. Then the second bar will push down the raw silk on the first crochet hook, and the raw silk on the second crochet hook will be pushed down. The third retaining bar is pushed down and moves in sequence to realize that the raw silk on all crochet hooks falls off simultaneously and completes the overall dehooking action, as shown in Figure 10-6(c).
(2) Refining barrel and lifting mechanism: The refining barrel is a standing cylindrical shape, with cylinder dimensions of 1300mm×2000mm and 1400mm×2000mm. Its structural composition is shown in Figure 10-7. Similar to the refining tank hanging refining, the star-shaped refining barrels are usually in groups of 5 to 9.
The lifting mechanism is composed of a motor 1, an eccentric wheel 2, a standing column 3 and a lever 4, which can make the star frame 5 hoisted on it and the silk training silk rise and fall in the training liquid. The lifting stroke is 200~330mm, and the lifting frequency is 5 times/min. The heating system consists of a direct steam pipe 10, an indirect steam pipe 9 and a temperature control device 8. The direct steam heating is mainly used in the temperature rise stage, and the indirect steam heating is mainly used in the heat preservation stage. It has a temperature control sensor and has high temperature control accuracy (±1°C). ), the maximum operating temperature is 100℃.
(3) Water circulation rolling machine: The rolling machine is a supporting equipment for the star frame refining process. It mainly consists of a silk feed frame, a water washing tank, a circulation pump, etc., as shown in Figure 10-8.




The silk feed frame 6 of the rolling machine is located above the rear water tank 3. There are 4 pulleys below that can move forward and backward. When the refined silk is to be dropped off from the star frame into the front and rear water troughs at once, first move the silk inlet frame to the front of the machine, hoist the silk into the rear water trough from above, and then pull the silk inlet frame It returns to the rear position and is fixed by the positioning pin 5. After the fabric enters the rear water tank, the circulation pump 1 is started to suck the water in the front and rear water tanks. At the water nozzle 4, the water flows downward at a higher speed and passes through the arc-shaped bottom of the tank. The direction of the water flow changes, causing the rear water tank to The water in the tank keeps flowing in the direction shown by the arrow in the figure. During this process, the circulating pump generates the impact kinetic energy of the water, which is gradually transmitted to the water in the entire tank, causing the water in the tank to form a rolling flow, and at the same time, the silk The circle also rolls with this water flow, and is smoothly pulled out of the water in the exit direction and enters the silk inlet rack. The regulating valve can be used to adjust the flow rate of the circulating water flow and control the speed of the water rolling in the tank so that the water flow speed matches the fabric winding speed. The silk entering the silk rack is expanded by the rubber bending roller, and then enters the guide rollers in the front water tank to squeeze water, and then is expanded and flattened by the wooden disc expansion roller and herringbone thread roller, and finally rolled by the friction rolling device. Wrap into a roll of damp cloth.
The application characteristics of star frame scouring: star frame scouring and degumming are even, which can prevent white fog and block defects, and can solve the problem of heavy twill, spun, crepe, and satin silk fabrics that are prone to occur when scouring in the scouring tank. Hanging loops and wrinkles, etc. It uses many evenly distributed hook needles to evenly hook the fabric during scouring, avoiding the loop wrinkles caused by the different lengths and uneven force of the loop ropes during the scouring process. Therefore, it is suitable for dense and heavy electric spinning. The scouring of class and twill silk. At the same time, after the silk is hoisted into the barrel, the labor intensity is greatly reduced due to the automatic control of temperature and fabric lifting.
