Description

Technical Field

[0001] The utility model belongs to the technical field of textile dyeing and relates to a normal temperature automatic roller dyeing machine. Background Art

[0002] In the textile industry, fabric dyeing is a critical processing step that directly impacts the quality of the final product. Traditional dyeing methods primarily include dip dyeing, jig dyeing, pad dyeing, and printing. Among these, jiggers are widely used because they can achieve continuous and uniform dyeing. However, traditional jiggers have numerous deficiencies in practical applications and are in urgent need of improvement. A jigger operates by unwinding the fabric from a reel and, guided by multiple guide and winding rollers, repeatedly winding and squeezing the fabric in the dye solution to ensure uniform dye penetration into the fibers. Traditional jiggers typically operate at high temperatures, which not only increases energy consumption but can also damage fabrics made of certain sensitive materials. Therefore, room-temperature jiggers have emerged in recent years to address these issues.

[0003] By optimizing the dye liquor formula and dyeing process, room-temperature jiggers can achieve efficient dyeing results at room temperature. This equipment not only reduces energy consumption but also minimizes damage to the fabric, improving dyeing uniformity and stability. However, despite their excellent performance in many aspects, room-temperature jiggers still have some shortcomings in actual operation. First, existing jiggers require multiple back-and-forth squeezing and winding cycles to fully color the fabric. This process is not only time-consuming and reduces dyeing efficiency, but can also cause wrinkles and damage to the fabric during the multiple windings. Secondly, when dyeing the fabric, the head of the fabric must first be passed up and down through the cloth winding rollers and guide rollers so that the fabric can be inserted into the jigger for dyeing. This threading process is relatively cumbersome, increasing production costs and operational difficulty. Utility Model Content

[0004] The purpose of the utility model is to provide a normal temperature automatic dyeing machine, which can complete multiple extrusion windings at one time, so that the cloth can be fully colored and the dyeing efficiency can be improved. At the same time, the cloth guide rollers can rise to the same height, making the cloth transmission simpler and effectively reducing the difficulty of operation.

[0005] In order to solve the above technical problems, the utility model provides a normal temperature automatic dyeing machine, comprising a dyeing trough, wherein the two sides of the upper end of the dyeing trough are respectively rotatably connected to a feed cloth rolling roller and a discharge cloth rolling roller, a feed motor for driving the feed cloth rolling roller and a discharge motor for driving the discharge cloth rolling roller are installed outside the dyeing trough, and the upper end of the dyeing trough is rotatably connected between the feed cloth rolling roller and the discharge cloth rolling roller to a plurality of fixed cloth guide rollers arranged along the length direction of the feed cloth rolling roller, and the fixed cloth guide rollers are driven to rotate by the feed motor;

[0006] The dyeing trough is connected to lifting frames that can slide up and down at both ends of the fixed cloth guide roller. A hydraulic telescopic rod is installed on the outside of the dyeing trough for driving the corresponding lifting frame to rise and fall. The upper end of the telescopic shaft of each hydraulic telescopic rod is connected to the lower side of the corresponding lifting frame. Each lifting frame is downwardly provided with a plurality of downward extending rotating bars located between the two fixed cloth guide rollers, and the lifting cloth guide roller is rotatably connected between the two opposite downward extending rotating bars.

[0007] The dyeing trough is connected to a liquid inlet pipe extending into the interior thereof. The bottom of the dyeing trough is provided with a plurality of liquid inlet branch pipes connected to the liquid inlet pipe. Each liquid inlet branch pipe is provided with a plurality of liquid inlet spray holes arranged along its length direction.

[0008] By adopting the above technical solution, the fabric is first wound around the feed roll, and the hydraulic telescopic rod is controlled to extend, driving the lifting guide roller to rise above the fixed guide roller. The free end of the fabric is passed between the lifting guide roller and the fixed guide roller, and the head end is wound around the discharge roll. The discharge roll then remains stationary, and the feed roll rotates to release the fabric. The hydraulic telescopic rod shortens, driving the lifting guide roller down, pressing the fabric downward and immersing it in the dye solution. Finally, the feed roll and the discharge roll rotate slowly and synchronously, causing the fabric to be squeezed and wound back and forth repeatedly on the fixed guide roller and the lifting guide roller, fully contacting the dye solution, so that the fabric can be quickly and evenly dyed, allowing the fabric to be dyed continuously and quickly without back and forth movement. Dye is added to the dyeing tank through the liquid inlet pipe and liquid inlet branch pipe. If the dye solution is left to stand for a long time and the dye settles at the bottom, water is sprayed to the bottom through the liquid inlet nozzle when adding dye, flushing the dye at the bottom and mixing it into the dye solution, effectively preventing the dye from settling to the bottom.

[0009] The utility model is further configured such that a driving pulley is provided at one end of the feed cloth winding roller, and a transmission pulley located on the same side as the driving pulley is provided at one end of each fixed cloth guide roller, and the driving pulley and each transmission pulley are connected in pairs through belt transmission.

[0010] The utility model is further configured such that each liquid inlet spray hole is opened on both sides of the liquid inlet branch pipe in an inclined downward direction.

[0011] The present invention is further configured such that a drainage pipe communicating with the interior of the dyeing trough is provided at the lower portion of the outer side of the dyeing trough, and a valve is provided on the drainage pipe.

[0012] The present invention is further configured such that the dyeing trough is provided with reflux troughs on both sides thereof, the reflux troughs being located below the feed cloth roller or the discharge cloth roller, and the bottom of each reflux trough is inclined downward and communicated with the dyeing trough.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the utility model uses the staggered coordination of the fixed cloth guide roller and the lifting cloth guide roller. When the cloth is dyed, the cloth can be squeezed and wound back and forth on the fixed cloth guide roller and the lifting cloth guide roller many times, so that the cloth can be dyed quickly and evenly, so that the cloth can be dyed continuously and quickly without going back and forth, thereby effectively improving the dyeing efficiency.

[0015] Secondly, the lifting guide roller of the utility model can be controlled to move up and down. When threading the cloth, the lifting guide roller rises to be higher than the fixed guide roller, so that the cloth can be easily passed between the fixed guide roller and the lifting guide roller. Then the lifting guide roller descends to press the cloth down and immerse it in the dye solution, so that dyeing can be carried out. The cloth transmission is simpler and the operation difficulty is effectively reduced.

[0016] Third, the present invention adds dyeing liquid through the liquid inlet branch pipe. If the dyeing liquid settles to the bottom for a long time, water is sprayed to the bottom through the liquid inlet nozzle when adding dyeing liquid to wash up the dye at the bottom and continue to mix it into the dyeing liquid, effectively preventing the dye from settling to the bottom.

[0024] The dyeing trough 1 is connected to a lifting frame 11 that can slide up and down at both ends of the fixed guide roller 7.
