Description

Technical Field

[0001] This application relates to the field of airflow dyeing machines, and more particularly to a discharge device for an airflow dyeing machine. Background Technology

[0002] Airflow dyeing machines utilize aerodynamic principles. Under the action of an airflow circulation fan, a strong airflow is formed inside the dyeing vat. The fabric is circulated and dyed under the traction of the airflow. After dyeing, the fabric is folded in a trolley through the discharge device for transport to subsequent equipment.

[0003] Currently, Chinese utility model patent CN207597099U discloses a fabric feeding and unloading device for a dyeing machine, including a transverse moving ring, a dyeing vat, a transmission belt, and a reduction motor. The dyeing vat contains a fabric body, one end of which passes through the vat's outlet and connects to the transverse moving ring. Above the transverse moving ring is an output roller connected to the reduction motor. A cam is connected to one end of a push rod, and the other end of the push rod is connected to one side of the unloading hopper. One end of the fabric body is in close contact with the output roller, and this end is located below the inside of the fabric cart. One end of the transverse moving ring is fixedly connected to the telescopic end of a cylinder. This application offers advantages in work efficiency and cost reduction.

[0004] During the dyeing process, the fabric is always in a wet environment in contact with dye liquor, water, and auxiliaries. As the fabric is discharged, it undergoes simple dehydration and draining, but a large amount of moisture remains. The fabric is then stacked in the fabric cart by the action of the stacking bucket. Under the influence of gravity, the fabric is squeezed against the fabric below, squeezing out the dye from the original fabric. The moisture in the stacking bucket is difficult to remove, which can easily cause dye migration, change the color of the fabric, and affect the quality of the fabric. Utility Model Content

[0005] In order to reduce the accumulation of dye in the fabric cart and reduce dye migration, this application provides a discharge device for an airflow dyeing machine.

[0006] The discharge device of the airflow dyeing machine provided in this application adopts the following technical solution:

[0007] A discharge device for an airflow dyeing machine includes a fabric discharge frame, a fabric swaying device, a parking platform, and a fabric cart. The fabric discharge frame is located on one side of the dyeing machine, the fabric swaying device is located on the fabric discharge frame, the parking platform is located below the fabric swaying device, the parking platform is located on the fabric discharge frame, the fabric cart is placed on the parking platform, and the fabric cart has an outlet hole for dye to flow out.

[0008] By adopting the above technical solution, the problem of dye being difficult to remove from the fabric cart when the fabric is stacked due to gravity extrusion is solved by opening an outlet hole for dye to flow out. Excess dye or water squeezed out of the fabric can be removed from the fabric in time through the outlet hole, reducing dye migration caused by liquid accumulation in the fabric cart, reducing the risk of uneven fabric color, and improving fabric quality. At the same time, the cooperation between the parking platform and the fabric cart enables stable support of the stacked fabric.

[0009] Optionally, the parking platform is provided with a guide groove that extends along the direction from the fabric rack to the dyeing machine. The guide groove is only for placing the rollers of the fabric cart. A limit block is provided in the guide groove to restrict the movement of the fabric cart located below the fabric arrangement device.

[0010] By adopting the above technical solution, the guide groove matches the shape of the fabric cart rollers to achieve rapid positioning of the fabric cart, ensuring that the fabric cart is accurately aligned with the bottom of the fabric placement device, and avoiding the fabric from being scattered due to the offset position of the fabric cart; the limiting block further restricts the movement of the fabric cart, ensuring that the position of the fabric cart is stable during the stacking process, reducing uneven fabric compression caused by the shaking of the fabric cart, indirectly reducing the possibility of dye migration, and improving stacking efficiency and stability.

[0011] Optionally, the upper surface of the parking platform is provided with a plurality of drainage holes, the parking platform is provided with a cavity, the cavity is connected to the drainage holes, and a drainage pipe for draining liquid from the cavity is provided on one side of the parking platform.

[0012] By adopting the above technical solution, the liquid discharged from the outlet of the fabric cart may accumulate on the parking platform. The drain hole guides the liquid into the cavity and then discharges it through the drain pipe, realizing the rapid removal of the accumulated liquid. This avoids problems such as dye residue pollution or a humid working environment caused by the liquid remaining on the parking platform, keeping the area around the equipment clean and reducing the risk of secondary pollution.

[0013] Optionally, a squeegee assembly is provided in the cavity. The squeegee assembly includes a squeegee blade and a push rod. The squeegee blade is slidably connected to the cavity along the direction from the fabric rack to the dyeing machine. The squeegee blade abuts against the inner side wall of the cavity. The push rod is disposed on the squeegee blade and extends out of the parking platform.

[0014] By adopting the above technical solution, the problem of liquid residue or sediment accumulation in the cavity is solved; by pushing the scraper blade along the cavity with the push rod, the residual liquid, dye sediment and other substances in the cavity can be scraped to the drain outlet, which improves the drainage efficiency of the cavity, avoids liquid accumulation and deterioration or blockage of the drain hole, ensures the long-term stable operation of the parking platform and reduces equipment maintenance costs.

[0015] Optionally, the fabric output frame is equipped with a dewatering device, which includes a dewatering roller, an abutment roller, an abutment block, a cylinder, and a dewatering motor. The dewatering roller is rotatably connected to the fabric output frame, and the dewatering motor is used to drive the dewatering roller to rotate. The abutment block is slidably connected to the fabric output frame in a direction close to or away from the dewatering roller, and the abutment roller is rotatably connected to the abutment block. The cylinder is used to drive the abutment block to move.

[0016] By adopting the above technical solution, the abutment roller and the squeezing roller are driven by a cylinder to actively squeeze and dehydrate the fabric during the discharge process. Compared with passive dripping, active squeezing can significantly reduce the moisture content of the fabric, reduce the amount of dye discharged due to gravity during subsequent stacking from the source, effectively alleviate dye migration, and improve the uniformity of fabric dyeing.

[0017] Optionally, a water receiving device is provided below the dewatering device. The water receiving device includes a water receiving platform, an adjusting screw, and an adjusting motor. The water receiving platform is slidably connected to the fabric output frame in a vertical direction. The length direction of the adjusting screw is parallel to the sliding direction of the water receiving platform. The adjusting screw is rotatably connected to the fabric output frame. The water receiving platform is threadedly connected to the adjusting screw. The adjusting motor is used to drive the adjusting screw to rotate.

[0018] By adopting the above technical solution, the problem of water splashing during the squeezing process is solved; by adjusting the height of the water receiving platform by adjusting the motor drive screw, it can be precisely adapted to different fabric thicknesses or squeezing positions, ensuring that the liquid generated during squeezing is completely collected, avoiding water droplet contamination of equipment or working environment, and improving the working condition adaptability of the water receiving device.

[0019] Optionally, a drain pipe is provided at the bottom of the water receiving platform, the drain pipe is connected to the inside of the water receiving platform, and a cap is threaded onto the drain pipe.

[0020] By adopting the above technical solutions, the controlled discharge of liquid collected in the water receiving platform can be achieved. The drain pipe facilitates the centralized treatment of collected dyes or wastewater, avoiding pollution caused by random dumping. The cover can be closed when not draining to prevent odors from escaping or impurities from entering the water receiving platform, keeping the inside of the platform clean and improving the ease of use of the equipment.

[0021] Optionally, the side wall of the fabric cart is provided with several flow holes for air to contact the fabric.

[0022] By adopting the above technical solution, the problem of poor air permeability after the fabric is stacked in the fabric cart is solved; the circulation holes promote air circulation inside and outside the fabric cart, accelerate the evaporation of fabric moisture, and reduce the problem of bacterial growth or local dampness caused by long-term accumulation of wet fabric; at the same time, air circulation can reduce the humidity difference between fabrics, further alleviate dye migration caused by uneven humidity, and improve the drying efficiency and storage quality of fabric.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using a dewatering device, the fabric is actively squeezed and dehydrated during the discharge process, which significantly reduces the moisture content of the fabric. This reduces the amount of dye discharged due to gravity during subsequent stacking, effectively alleviates dye migration, avoids uneven fabric color, improves the uniformity of fabric dyeing, and ultimately improves the quality of the fabric.

[0025] 2. The drainage holes, cavities, and drainage pipes installed on the parking platform can collect and discharge the liquid flowing out of the fabric cart in a timely manner, preventing the liquid from accumulating on the parking platform, preventing dye residue pollution and damp working environment problems, and keeping the area around the equipment clean.

[0026] 3. Openings at the bottom and side walls of the fabric cart can reduce the accumulation of dye inside the cart and reduce dye migration in the fabric. Attached Figure Description
