[0035] The present invention provides an anti-bending device for scouring and bleaching equipment, scouring and bleaching equipment, and anti-bending method. In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the following will be combined with the drawings and embodiments. The invention is described in further detail.
[0036] The present invention provides an anti-folding device for scouring and bleaching equipment, which allows fabrics to accumulate between the blades of the rotary impeller through structural restrictions, and fully self-swells in a relaxed state, providing excellent raw materials for the production of high-flatness fabrics. Its basic structure is like figure 1 As shown, the fabric 3 is guided by the fabric introduction roller 1 into the following fabric soaking container 4; the fabric 3 enters the hot water 28 of the fabric soaking container 4, and continuously passes through the hot water 28 in a stacked state; The fabric in the fabric soaking container is guided out and enters the next process. In addition, a rotating impeller 5 is provided in the fabric infiltration container 4, so that the fabric 3 soaked in the hot water 28 forms a stacking state of continuous backward accumulation under the continuous turning of the blades of the rotating impeller 5; the interior of the fabric infiltration container 4 A first steam heating pipe 6 for heating the water body in the container is provided, and a cloth air pipe 7 for blowing hot water 28 to fully relax the fabric 3 of the accumulated folded-up section; The first steam heating pipe 6 is arranged below the fabric support board 8, and the air distribution pipe 7 is arranged above the fabric support board 8. The fabric lead-out roller 2 is provided with a first for blowing the swelling of the fabric 3. A blowing part, the first blowing part includes at least two blowing pipes 35. The above-mentioned rotary impeller 5 may be an intermittent rotary impeller. The intermittent rotary impeller 5 rotates at a certain angle in an orderly manner. The fabric 3 can form a stack between two adjacent blades of the rotating impeller 5, and the fabric 3 is on the guide roller. Under the action of, the fabric 3 between the two blades is stacked at a constant speed between the blades of the intermittent rotary impeller. When the fabric 3 between the two blades reaches a certain length or weight, the blades rotate at a certain angle, and the fabric 3 is introduced into the hot water 28 for loose stacking. 3 Fully swell by itself in a relaxed state in the fabric soaking container 4. The use of an intermittent rotary impeller increases the swelling time of the fabric 3 in the fabric soaking container 4, so that the fabric 3 relaxes and swells better.
