Introduction to the structure and function of the opener

      The diameter of the opener beater is 610 mm, and there are 19 discs on the beater uranium (the distance between the discs is 54 mm~, each disc is equipped with 12 blades, the blade is 6 mm thick and 30 mm wide. Blades and discs Not on the same plane, but inclined to both sides of the disc at different angles, so that every point of the cotton layer in each rotation of the beater can be hit 1 to 2 times. According to the actual measurement, the hit point of the A 036 porcupine beater Distribution. It can be seen from the figure that in the first half of the beater's turn, the cotton layer between the two adjacent discs is hit by the first to sixth blades on each disc, and in the second half of the turn, the cotton layer is hit by the first to sixth blades. 7~12 blades hit. The chimney is hit by high-speed and high-quality typing in the gripping state of the cotton layer, forming a greater hitting force. At the same time, the beater blade is inserted into the cotton layer to play a partial role, so successively from the bridge: The cotton block is torn off from the layer and hits the dust ficus with a large punch. Under the action of the beater and the dust stick, the cotton block is opened, and the impurities are bathed through the gap of the dust stick. The effect of the beater to loose and remove impurities is as follows Process parameters related:

1. The speed of the beater's speed of the opener directly affects the strength of the beater's impact on the cotton layer. When the cotton worm is used regularly, the speed of the beater is high, the opening and impurity removal are good. However, if the speed is too high, the impurities are easy to break, and it is easy to sway white flowers or tight cotton bundles, and the trash content of the noil is reduced instead. The speed of the beater is generally 50,000 rpm. When processing original bridges with long fibers, less impurities, or poor maturity, lower thugs are usually used.

2. The gap between the beater and the cotton roller of the opener will affect the tearing force of the beater blade deep into the cotton layer. The gap is small and the opening effect is good, but if it is too small, it is easy to damage the fiber. A036 Japanese-style porcupine opener is suitable for spinning cotton fibers below 31 mm. The gap is 6 mm and cannot be adjusted. When processing chemical fibers, the reference distance is 11 mm.

3. The distance from the beater to the dust stick gradually loosens and increases in volume as the cotton block gradually increases. This distance gradually enlarges from the inlet to the outlet. When the gap is small, the chance of the cotton block being blocked by the dust rod increases, and the noil increases. Conversely, when the gauge is large, the noil decreases. Normally spinning medium-sized yarn, the inlet gage is 10-12 mm, and the outlet gauze is 17-18.5 mm. Since this gauge is not easy to adjust, it is generally not adjusted when the raw cotton properties change little.

4. The distance between the beater of the opener and the stripping knife should be smaller, generally 1.5~2 mm. When it is too large, the beater will return to the flower and cause the thread to come.

In the dust bin, since there is more airflow and less debris, the distance is the smallest. It should be pointed out that in some industries, due to the different machine structure, combined with the air comb control, the dust rod interval from the inlet to the outlet also adopts large, small and large configurations.
