Technical Field

The invention relates to a dyeing machine for realizing multifunctional treatment by combining nozzles, which is an improvement on dyeing and washing processes and belongs to the technical field of dyeing equipment.

Background

The common high-temperature dyeing machine has a main structure of a cloth lifting cylinder, a dyeing nozzle, a cloth guide pipe and a cloth storage tank. In the dyeing process, a cloth lifting cylinder is generally used to introduce a continuous loop-shaped fabric into a dyeing nozzle, so that dye is sprayed onto the fabric, and meanwhile, the fabric is driven to enter a cloth guide pipeline by utilizing the tensile force generated by the spraying. When the fabric is discharged from the cloth guide tube, the fabric drops into the cloth storage tank due to its own weight. Since the length of the fabric to be treated is generally many times longer than the storage tank, the fabric is formed into a stacked state in the storage tank. The stacked fabrics are extruded and pushed by the weight of the fabrics in the cloth storage tank, then are sent back to the dyeing nozzle by the attraction of the cloth lifting cylinder and the dyeing nozzle to receive the dye liquor for spraying, and then are returned back to the cloth storage tank again to form the stack, and then another spray dyeing cycle is started. After the dyeing process is finished, the dyeing solution in the dye vat is recovered, the nozzle is changed into spraying clear water, the fabric is continuously driven to circularly run in the dyeing machine, and the saturated dye attached to the surface of the fabric is removed by changing water for cleaning for multiple times.

Traditionally, dyeing machines have mostly mixed water and pigment as a medium carrying the dye, the liquid dyeing nozzle used being called an overflow nozzle. However, the use of water as a pigment-carrying medium also results in the use of higher hydraulic pressures, higher temperatures, more expensive equipment and more energy consumption due to the relatively high density and specific heat of water. At the same time, the amount of water used (bath ratio) is high, and different types of textile fibers have different properties, such as tight weave, lightness, thinness, and softness, and thus require different dyeing and washing processes. The dyeing effect is also affected by the type, color, weight and proportion of dye, so that it is difficult to deal with complicated fabric and dye variables by simply using the overflow nozzle design.

Conversely, air, which is lighter than water, is also a fluid medium that can be used to carry the pigment, and is applied by mixing the air and the dye liquor into an atomized state using a specially designed atomizing nozzle, allowing fine pigment particles to be propelled into the fabric fiber structure by the atomized air. The atomizing nozzle has certain advantages in treating certain fabrics, such as soft fabrics, because the compressed atomizing nozzle can be used for stretching the fabrics, the twisted fabrics are easy to separate, and meanwhile, the fabrics are prevented from being excessively extruded by high-pressure dye liquor to lose the soft texture, so that the fabrics are circulated more smoothly, and the problem of dyeing marks is reduced.

Generally speaking, both water (liquid) and air (gas) can be used as the two mediums carrying the pigment, each of them has advantages and disadvantages, and has different operation requirements, if they can be combined together for use, it can flexibly respond to various complicated dyeing and washing process requirements. Therefore, the invention is particularly applied to improve the dyeing and washing technology and efficiency by using the dyeing machine which realizes multifunctional treatment by using the nozzle combination.

The nozzles propelled by the two different media can push pigment molecules into the structure of the fabric fiber, and simultaneously, the fabric is driven to circularly and continuously receive the spraying and spreading effects of the nozzles in the dyeing machine by utilizing the jet force.

Specifically, the multifunctional treatment dyeing machine comprises a dye vat, a cloth lifting cylinder, a swinging bucket and a cloth storage tank, and is characterized by further comprising a first nozzle arranged between the dye vat and the cloth lifting cylinder and a second nozzle arranged behind the first nozzle, wherein a nozzle gap of the first nozzle and/or the second nozzle is fixed, or a nozzle adjusting device capable of adjusting the nozzle gap is arranged on the first nozzle and/or the second nozzle.

Furthermore, the nozzle adjusting device comprises an adjustable nozzle driver, an adjustable nozzle ball screw and a nut, wherein the adjustable nozzle driver is connected with and drives the adjustable nozzle ball screw, the nut is arranged at the tail end of the adjustable nozzle ball screw, and the adjustable nozzle driver rotates the adjustable nozzle ball screw to move linearly along the axis of the nut, so that the size of the gap of the annular nozzle is increased or reduced.

Furthermore, the first nozzle is provided with a first nozzle water inlet and a first nozzle air inlet which are respectively communicated with the first nozzle, the first nozzle water inlet supplies dye liquor or cleaning water to the first nozzle, and the first nozzle air inlet supplies pressure air to the first nozzle by an air pump to form atomization. The first nozzle has two functions, the first is to push the cloth head of the fabric to the cloth lifting cylinder by the nozzle thrust force to pull the fabric, and the second is to perform the relative spray dyeing and cleaning functions during the dyeing and washing processes.

Furthermore, the first nozzle is provided with a high-efficiency washing device which is used for extruding part of the dye liquor adsorbed on the fabric by a mechanical rolling method.

Furthermore, the efficient washing device comprises an upper roll shaft and a lower roll shaft, parallel fabrics enter a gap between the upper roll shaft and the lower roll shaft, and bearings at two ends of the upper roll shaft and/or the lower roll shaft can move up and down, so that the gap can be reduced in the fabric washing process, and the dye liquor is squeezed out.

Furthermore, a cloth swinging device for driving the swinging hopper is further arranged on the swinging hopper.

In the application of the invention, the overflow nozzle is generally composed of a conical outer shell and a conical inner nozzle, a circular ring gap is formed between the outer shell and the inner nozzle, the dye liquor formed by mixing water and pigment is input from the outer shell of the overflow nozzle by the hydraulic pump and then overflows from the circular ring gap, and the flowing speed of the dye liquor in the gap is improved due to the fact that the conical cross section of the circular ring gap is continuously narrowed, and a high-speed spraying state is formed. When the dye liquor is sprayed on the surface of the fabric, a propelling force is generated to drag the fabric to advance, and meanwhile, fine pigment molecules are also pressed into the fiber structure of the fabric, so that the dyeing effect is caused.

The atomizing nozzle is generally composed of a conical outer shell and a conical inner nozzle, a circular ring gap is formed between the outer shell and the inner nozzle, the hydraulic pump inputs dye liquor formed by mixing water and pigment from the outer shell of the atomizing nozzle, but the air pump also inputs high-pressure air to be mixed with the dye liquor and then overflow from the circular ring gap to form a spraying state, when the atomized dye liquor is sprayed to the surface of a fabric, propelling force and tension are also generated to pull the fabric to advance, and meanwhile, fine pigment molecules are also pressed into a fabric fiber structure to cause a dyeing effect.

Further, the annular gap of the second nozzle of the dyeing machine can be fixed or adjustable, so that the spraying speed or the range size can be adjusted. The annular gap of the nozzle can be adjusted to switch the operation modes of the overflow nozzle and the atomizing nozzle, and the operation modes of the nozzle of the dyeing machine can be interchanged by controlling the size of the gap.

Furthermore, the gap of the second nozzle is reduced, so that the jet flow speed can be accelerated, the propelling force is brought to the fabric, and meanwhile, pigment molecules can be forced into the fiber. If the gap of the nozzle is enlarged, the flow of the atomized dye liquor is improved, and meanwhile, the propelling force can be brought to the fabric to continuously drive the fabric to advance.

The dyeing machine can meet the requirements of air flow or overflow use by automatically adjusting the nozzle gap, flexibly replace various operation modes, select proper process modes for boiling, bleaching, dyeing and washing by a user, and effectively widen the applicability of the process and the fabric. When the water washing process is carried out, the function of dragging the fabric is still provided under the overflow mode or the atomization mode of the second nozzle, but the spraying action of the nozzle is changed into the cleaning of the saturated dye attached to the surface of the fabric because the dye liquor is changed into clear water. Meanwhile, a high-efficiency washing device is arranged above the first nozzle in the design, and the device is matched with the whole-course water flow mode of the first nozzle and the second nozzle, so that a more effective washing effect is achieved.

The high-efficiency washing device is used for extruding part of dye liquor adsorbed on the fabric by a mechanical rolling method. The high-efficiency washing device comprises an upper roll shaft and a lower roll shaft, and parallel fabrics enter a gap formed by the middle gap surfaces of the two roll shafts. The bearings at the two ends of the upper roller shaft can synchronously move up and down, so that the size of the fabric entering the gap of the high-efficiency washing device can be adjusted, the dewatering amount of the fabric leaving the high-efficiency washing device can be adjusted, and the gap is enlarged to allow the dyed fabric to freely pass through during dyeing.

Detailed Description

The technical solution described in the present application is described below in a non-limiting manner with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the present invention relates to a dyeing machine using a combination of an overflow nozzle and an atomizing nozzle. A continuous loop of fabric (not shown) first enters the first nozzle 2 and then passes through the gap between the upper roller 3 and the lower roller 4, and is drawn by the fabric lifting cylinder 5 to the second nozzle 9. The fabric is subjected to the jet thrust of the second nozzle 9 and reaches a swing bucket 14 provided with a swing device 13, and the fabric is discharged from the swing bucket 14 and drops into a cloth storage tank 17 at the bottom of the dye vat 1 to form a stacked fabric. The stacked fabrics are extruded and pushed by the weight of the fabrics in the cloth storage groove 17, then are dragged by the first nozzle 2 and the cloth lifting cylinder 5 to be sent back, then are sprayed by the second nozzle 9, and then are returned to the cloth storage groove 17 to form a stack, so that the circular spray dyeing is carried out.

The first nozzle inlet 15 supplies dye liquor or cleaning water to the first nozzle 2, and the first nozzle inlet 16 supplies pressurized air to the first nozzle 2 by an air pump to form an atomized mist. The first nozzle 2 has two functions, the first point is that the cloth head of the fabric is pushed to the cloth lifting cylinder 5 above by using the nozzle pushing force during the cloth feeding process so that the fabric is dragged by the cloth head, and the second point is that the opposite spray dyeing and cleaning functions are exerted during the dyeing and water washing processes.

The isolation valve 10 and the rear overflow nozzle inlet valve 11 are used to control the entrance of the dye liquor, the fresh water and the pressurized air into the second nozzle 9, and support the switching of the overflow nozzle operation mode and the atomizing nozzle operation mode of the second nozzle 9. Meanwhile, the annular nozzle gap size of the second nozzle 9 can be adjusted through the adjustable nozzle ball screw 6 and the adjustable nozzle driver 7, so that the spraying speed and the spraying range degree of the automatic adjusting nozzle are achieved. The adjustable nozzle driver 7 is connected with and drives the adjustable nozzle ball screw 6, the nut 8 is arranged at the tail end of the adjustable nozzle ball screw 6, and the adjustable nozzle driver 7 rotates the adjustable nozzle ball screw 6 to linearly move back and forth along the axis of the nut 8, so that the size of the annular nozzle gap is increased or reduced.

The gap adjustment can be used for switching the operation modes of the overflow nozzle and the atomizing nozzle, when the distance is adjusted to be larger, the gap adjustment is switched to the atomizing nozzle, and when the distance is adjusted to be smaller, the gap adjustment is switched to the overflow nozzle. The adjustable gap design of the second nozzle 9 can meet the requirements of airflow or overflow use, and the combined function of the first nozzle 2 is added, so that an airflow mode, a water flow mode, an air fog mode and a liquid fog mode are realized, and a user can select a proper process mode to deal with different treatment procedures and different fabric varieties.

An upper roll shaft 3 of the efficient washing device and a lower roll shaft 4 of the efficient washing device are arranged above the first nozzle 2, parallel fabric entering gaps are formed between the upper roll shaft 3 and the lower roll shaft 4, and bearings (not shown in the figure) at two ends of the upper roll shaft 3 can move up and down, so that the gaps can be reduced in the fabric washing process, and dye liquor can be squeezed out. The water washing program of the dyeing machine is applied by matching with the whole water flow modes of the first nozzle 2 and the second nozzle 9. The efficient washing device can effectively extrude part of dye liquor adsorbed on the cloth by a mechanical rolling method, increase effective water exchange rate, and reduce the number of times of washing water for dyeing in each cylinder, thereby reducing water consumption.

It should be understood that the above description, including the accompanying drawings, is not intended to limit the described embodiments, and in fact, modifications, including variations in size, shape, materials used, and substitution of functionally similar elements, all of which are within the scope of the invention as claimed, are equally or approximately applicable.
