Description

Fabric pre-treatment device

Technical Field

The invention relates to the field of dyeing and finishing equipment, and in particular to a fabric pre-treatment device.

Background Art

Before dyeing, printing and finishing, textiles need to be desized, scour and bleached. The purpose is to remove natural impurities on the fiber, as well as the sizing agent and oil stains applied during textile processing, so that the fiber can fully exert its excellent quality and make the fabric white, soft and permeable. Pre-treatment equipment is a type of equipment that performs the above textile processing.

The invention patent application of Chinese patent publication number CN116180366A discloses a continuous soap washing machine for knitted fabrics, which has a soap washing pre-equipment, which includes, in the order of knitted fabric operation: a dual-purpose cloth feeding rack, an immersion tank, a No. 1 two-roller rolling car, a first mesh belt stacking box and a No. 2 two-roller rolling car, a stacking mesh belt is installed at the lower part of the first mesh belt stacking box, and an anti-drifting pressure cloth rope is arranged above the stacking mesh belt. The device can spray wash the fabric in a loose stacking manner through the stacking mesh belt, thereby extending the washing time of the fabric and achieving the degreasing washing effect of the fabric. The anti-drifting pressure cloth rope can press the fabric in the water to prevent the fabric from floating on the water surface and not being thoroughly washed. It has the advantages of simple structure and reliable control. However, in actual use, oil stains are often found on the mesh roller of the anti-floating pressure rope at the cloth outlet and on both sides of the position where the fabric leaves the liquid surface. Operators often mistakenly believe that the cleaning effect is poor, so they will deal with the floating oil problem by adding auxiliary spray or frequently changing the cleaning liquid, but the effect is not very ideal, and the production cost is increased, causing some companies to dare not use mesh belt boxes. In view of this, it is urgent to transform the mesh belt stacking box type washing equipment to improve its washing effect.

Summary of the invention

The object of the present invention is to provide a fabric pre-treatment device which can solve the "re-sticking" phenomenon occurring on both sides of the fabric at the position where the fabric is lifted from the liquid surface.

The technical scheme for achieving the purpose of the present invention is: a fabric pre-treatment device, comprising a fabric stacking mechanism installed in a water washing tank, a cloth pressing mechanism for preventing the fabric from floating is installed above the fabric stacking mechanism, the water washing tank has a cloth inlet end side and a cloth outlet end side, an overflow pipe is arranged on the water washing tank on the cloth outlet end side, the overflow pipe is located on both sides of the width direction of the fabric, the overflow pipe has an overflow port, a rotatable first oil separation mechanism is installed between the two overflow ports, the first oil separation mechanism comprises two first oil separation rollers, the two first oil separation rollers are respectively located on both sides of the front and back sides of the position where the fabric leaves the liquid surface, and the shaft of the first oil separation roller The first oil-separating roller is parallel to the width direction of the fabric, the horizontal position of the first oil-separating roller is limited to the bottom of the first oil-separating roller being slightly lower than the liquid surface when in use, the first oil-separating roller comprises a first oil-separating roller body, and the middle part of the surface of the first oil-separating roller body is respectively provided with a first thread bar and a second thread bar towards the two end sides of the first oil-separating roller body, and the rotation direction of the first thread bar and the second thread bar is limited to the first thread bar and the second thread bar both rotating outward during rotation; a first protective cover is provided between the first oil-separating roller and the fabric to prevent the first oil-separating roller from throwing the floating oil on the liquid surface onto the fabric during rotation, and the two ends of the first protective cover are fixed to the washing tank.

Furthermore, the first shield near the fabric inlet side extends an extension portion toward the bottom of the first oil separation roller adjacent to the first shield and one side of the fabric stacking mechanism, and the extension portion further separates the oil stains on the water surface from the fabric.

Furthermore, a first spray mechanism for spraying the fabric is installed above each of the first oil-separating rollers, the first spray mechanism includes a first spray pipe, the first spray pipe is parallel to the width direction of the fabric, and the bottom of the first spray pipe is provided with a plurality of first spray holes spaced along the width direction of the fabric, the first spray holes face the fabric leaving the liquid surface. The first spray mechanism sprays downwards on both sides of the fabric, which can further prevent the fabric from staining the oil on the water surface back onto the fabric.

Furthermore, spray branches are extended upward from both ends of the first spray pipe, and a plurality of second spray holes are opened on the spray branches, and the second spray holes face the edge of the fabric in the width direction away from the liquid surface. The spray branches can slightly open the curled part and clean the residual oil and the like in the curled edge.

Furthermore, the spray branch pipe is in a "U" shape, which has a better effect on flushing the edges.

Furthermore, the cloth pressing mechanism includes a mesh belt, the mesh belt is sleeved on two mesh belt guide rollers, two rotatable second oil separation rollers are arranged between the two mesh belt guide rollers, the second oil separation rollers are arranged close to the cloth outlet side, the horizontal position of the second oil separation roller is limited to the bottom of the second oil separation roller being slightly lower than the liquid surface when in use, the axial direction of the second oil separation roller is parallel to the width direction of the fabric, and the second oil separation roller has the same shape as the first oil separation roller. The second oil separation roller is used to move the floating oil near the mesh belt guide roller close to the cloth outlet side to the two shaft ends, and flow out from the overflow pipe.

Furthermore, a second guard is installed above the second oil separation roller, the second guard is in the shape of an arc plate, and the second guard is coaxially arranged with the second oil separation roller to prevent floating oil from being thrown onto the mesh belt.

Furthermore, the mesh belt guide roller includes a roller shaft, and a plurality of annular support ring pieces are spaced along the axial direction of the roller shaft. The mesh belt guide roller is in a candied haws structure, and the floating oil is not easy to gather at the mesh belt guide roller, which is conducive to the floating oil quickly passing through the mesh belt immersed in water to the overflow ports at both ends.

Furthermore, a second spray mechanism for spraying the mesh belt guide roller is installed above the mesh belt guide roller on the cloth outlet side. In order to prevent the small amount of oil that is missed from continuing to pollute and re-stick and to prevent the water level in the area from dropping after the second oil separation roller is added to separate the oil, which will bring about the opposite effect, a second spray mechanism is provided, and the second spray mechanism sprays the mesh belt guide roller on the cloth outlet side to clean the mesh belt guide roller, and the spray liquid falls into the water to replenish the liquid level.

The inventor has found that when the oil stains on the fabric are washed into water, part of them will be emulsified in the water, and part of them will gradually gather into agglomerates due to the high concentration. The light oil stains float on the liquid surface. As the concentration of the oil stains on the liquid surface increases, the floating oil stains will adhere to the components in contact with them. Since the liquid is added from the cloth feeding direction and an overflow pipe is set in the cloth outlet direction, the floating oil will most likely contaminate the mesh roller of the anti-drifting cloth pressing rope at the cloth outlet end, and directly contaminate the fabric on both sides of the position where the fabric leaves the liquid surface, that is, the "re-sticking" phenomenon occurs. This phenomenon cannot be solved by simply adding additives and frequently changing the cleaning liquid. The fabric pre-treatment device realized by the present invention can transfer the oil and debris floating on the water surface to the two axial ends of the first oil-separating roller body through the rotation of the oil-separating roller on the cloth outlet side, and quickly flow to the overflow port, and finally be discharged and filtered through the overflow pipe. A first protective cover is provided behind each of the two oil-separating rollers to prevent the floating oil on the liquid surface from being thrown onto the fabric when the first oil-separating roller rotates, thereby preventing the "re-sticking" phenomenon from occurring on both sides of the fabric leaving the position where the fabric is lifted from the liquid surface. This scheme is easy to modify and has low cost, and improves the washing efficiency of the mesh belt stacking box type washing equipment.
