Multi-tube independent air supply dyeing machine

The invention relates to a dyeing machine, in particular to a multi-tube independent air supply air dyeing machine.

With the continuous deepening and strengthening of environmental protection policies, traditional printing and dyeing processes and equipment are in urgent need of further development. The airflow dyeing machine is a kind of equipment developed in this background. It has been widely praised in the world because of its advantages of small bath ratio, high efficiency and excellent dyeing effect. As shown in Figures 9 and 10, in a gas stream dyeing machine, the fabric (98) is driven by a high pressure gas stream generated by a loop fan (92). In the production process of the equipment, the contact exchange mode between the fabric and the dyeing liquid mainly has two forms of airflow atomization and air pressure penetration, wherein the airflow atomization is in the form of dyeing liquid passing through a loop pump (96) through a special nozzle (95). After that, a fine mist of particles is formed, and the fabric is mixed with the atomized dye solution at a driving pressure applied by high-speed air at the nozzle, and the dye solution diffuses and penetrates uniformly and fully into the fabric interface. During the dyeing process, the fabric only carries the dyeing liquid, and is not infiltrated in the dyeing liquid. The excess dyeing liquid on the fabric flows through the bypass to the bottom of the storage tank (97), and the fabric carrying the dyeing liquid is neatly stacked in the groove. Apply a Teflon-coated roller or guide tape to the body and slowly advance.

Although the existing airflow dyeing machine can reduce the bath ratio, the high power consumption of the fan makes many users deterred. Some manufacturers simply assemble a fan with a lower rated power, and the external power consumption of the machine is lower, but the result is that the variety and weight range of the fabric are greatly reduced. Because the rated power of the fan of the airflow dyeing machine is Designed to meet most of the fabric dyeing process, especially high-density and high-density fabrics must speed up the exchange frequency with the dyeing solution, and the insufficient power rating will cause uneven dyeing on the fabric.

The existing airflow dyeing machine generally adopts a single fan for air supply design, and uses one fan to provide airflow for multiple sets of dye pipes, which inevitably causes errors in the wind distribution and affects the production quality. Moreover, the long and rounded air duct also constitutes a lot of resistance to the wind flowing through, greatly reducing the efficiency of the wind turbine supply. Because the power of a single fan is limited, under the reasonable use conditions, the largest fan on the market can only supply the wind power required by 6 dye pipes, which makes the air flow dyeing machine of more tubes fail to realize, which hinders the customer's dyeing factory. Production capacity.

If the length of each dyed tube is different in the dyeing of the same batch, the cycle time for each cloth to be sprayed through the nozzle is the same, and the requirements for the speed of each tube are different. Therefore, the current design of supplying a number of dye pipes to a wind turbine does not overcome the above difficulties.

In the case of de-loading dyeing, that is, when some dyeing tubes do not need to be dyed, the existing airflow dyeing machine can not relatively reduce the power, and can only continue to supply air to the empty-loaded dyeing tubes, resulting in unnecessary energy waste.

If in the dyeing process, when a certain dyeing tube is in an abnormal state, it needs to stop running. Because the current airflow dyeing machine adopts a single fan for air supply design, that is, all the dyeing tubes that are being operated need to be stopped synchronously. This will make the dyeing effect less than ideal.

In summary, the current airflow dyeing machine is not limited to many of the above-mentioned defects and problems, greatly affecting the efficiency of production, wasting energy, and limiting the flexibility of use.

The object of the present invention is to design a novel multi-pipe independent airflow dyeing machine capable of overcoming the above-mentioned deficiencies of the existing airflow dyeing machine design, which is an airflow dyeing machine which is energy efficient and can meet the requirements of the dyeing process.

Even if all the dye pipes are not used in the same production batch, the fans of the existing air dyeing machine cannot be adjusted accordingly. Even if the load is different, the rated power operation is required, and energy is inevitably wasted. The invention is different from the existing airflow dyeing machine, and the above advantages can effectively allocate energy and save unnecessary power consumption.

If the existing airflow dyeing machine encounters the condition of fabric knotting during operation, the fan must be turned off first, and the dyeing process can be continued after finishing, which will inevitably affect the fabrics that are normally walking in other pipelines, reducing the consistency, that is, causing the same batch. The color difference on the second. When the present invention encounters the above problems, the program with independent operation can ensure the normal operation of other pipelines, and the operation procedure is not hindered by the problematic pipeline.

The freestanding dye tube design of the present invention also increases machine load. In the prior art, a high-power fan is used in the airflow dyeing machine. In the prior art, only the wind power required for six dye pipes can be supplied in a shunt manner, otherwise the energy efficiency will be greatly reduced.

The invention also configures the components of the airflow dyeing machine such as the heat exchange system, the injection system, the dyeing liquid reflux system, and has a complete system device.

The structure and beneficial effects of the present invention are further illustrated by the embodiments of the present invention and the accompanying drawings. As shown in FIG. 1, the structure of the present invention includes a master cylinder (1), a fan (3), a cylinder head (2), and a suction. Wind pipe (4) and other components, wherein the fan (3) draws air from the inner cavity of the master cylinder (1), and the air flows through the air duct to the nozzle assembly (5), and an air filter is also avoided in the master cylinder (1). The dust is sucked into the fan (3).

Figure 1 is a perspective view showing one side of the airflow dyeing machine of the present invention, The working chamber is provided on the other side of the main cylinder of the air dyeing machine. During the dyeing work, the dyed fabric is introduced from the front working door of the cylinder, and the airflow in the cylinder sends the fabric to the main cylinder for circulation operation, passes through the lifting drum in the cylinder head, reaches the nozzle assembly, and the atomized dye liquid rides the wind. The spray assembly is sprayed onto the fabric and the fabric is run until the dyeing process is completed.

Figure 2 shows the external structure of the nozzle assembly of the present invention, including a first dyeing liquid conduit (6), a second dyeing liquid conduit (7), a nozzle head nozzle (8), and two nozzle heads having different spray amounts (9). ), (10). During operation, the dye liquor is sent to the catheter through the circulation system. The valve in the system is opened or closed as indicated by the operating instructions so that the dye liquor can enter the nozzle tip via the first or second dye conduit (6, 7). After the diversion, the first and second dyeing liquid conduits do not communicate with each other, and the two sets of nozzle heads (9), (10) are respectively connected.

Figure 3 further shows the nozzle assembly structure of the present invention comprising a nozzle housing (11), an upper nozzle barrel (12), a lower nozzle barrel (13), a shut-off ring (14), and a horseshoe-shaped baffle (15). ). The outer casing has a first dyeing conduit (6) and a second dyeing conduit (7). The nozzle housing (11) includes an airflow inlet (16), a fabric inlet (17) and a fabric outlet (18).

In the nozzle assembly structure of the present invention, a first nozzle opening (19) and a second nozzle opening (20) are provided. The gas stream enters the shell mixing atomized dye liquor through the inlet and is applied to the fabric through the first nozzle opening (19) and the second nozzle opening (20). The two nozzle openings are annular in shape and have the same width. The upper nozzle barrel (12) and the lower nozzle barrel (13) are concentrically mounted in the nozzle housing (11), wherein the gap between the upper nozzle barrel (12) and the lower nozzle barrel (13) is fixed The first nozzle port (19) can be adjusted by changing the distance between the nozzle barrels to meet the required jet pressure. In a typical design, the lower nozzle barrel (13) is generally fixed to the housing and the upper nozzle barrel (12) is relatively movable, however this is not limited by this design. An airflow inlet (16) is located on the side of the housing to direct airflow from the source to the housing. The nozzle housing (11) has a cylindrical shape, and the fabric inlet and outlet are disposed at both ends of the cylinder. For convenient connection, both ends and the airflow inlet (16) are connected to the flange. The shut-off ring (14) is mounted and fixed to the tail of the nozzle housing (11) to narrow the gap with the lower nozzle barrel (13), thus the gap between the shut-off ring (14) and the tail of the lower nozzle barrel (13) Defined as the second nozzle opening (20). The function of the second nozzle opening (20) is mainly to lift the fabric, so that a horseshoe-shaped baffle (15) is fixed and serves as a part of the annular nozzle outlet, so that the airflow can be concentrated under the nozzle to lift the fabric and The effect of the new design is very important, and the performance of the product is greatly improved.

A certain number of nozzle tip adapters (8) are attached to the periphery of the nozzle housing (11) in addition to the airflow inlet (16). Figure 4 is a cross-sectional view showing the nozzle tip connector (8) and its periphery. For ease of manufacture, the nozzle tip connector (8) and the nozzle tip are both ring-shaped, but the appearance is not limited to this. In operation, each individual nozzle head, such as (9), (10), is placed in the nozzle tip adapter (8), wherein the nozzle tip is screwed in until its dye channel opening (21) can take over the nozzle tip (8) The upper perforations (22) are aligned and fixed. The other end of the perforation is connected to a designated dye liquid conduit. In order to prevent leakage of the dye solution, some anti-leakage rings (23) are attached to the nozzle head nozzle (8) and the nozzle Between heads (9) and (10). In this embodiment, the dyeing liquid conduit is annular and is mounted to the periphery of the nozzle housing (11) to match the design of the nozzle tip socket (8). The dye solution conduit also has openings (24) in a plurality of locations for the dye solution to flow into the nozzle tip through the designated nozzle tip adapter (8). The arrows in Figure 4 indicate the flow of the dye liquor. As shown, the dye solution supplied to the nozzle head is only from one of the dye liquid conduits. The dye liquors of the different dye liquid conduits will be directed to the respective nozzle head sets without being connected to each other. The user can install and connect the nozzle head of the same flow rate to the same dye liquid conduit, and select the appropriate nozzle head group by operating the dye liquid conduit valve to obtain the desired spray dose. For example, the design of the present embodiment employs nozzle heads (9) and (10) of two different flow rates, one having a higher flow rate and the other having a lower flow rate. The user can choose to close the valve to the high flow nozzle head dye conduit and only open the valve to the low flow nozzle head dye conduit to achieve a relatively low spray volume. Conversely, a higher spray volume can be achieved if only the valve of the high flow nozzle head dyeing conduit is opened. However, the user can also further open both valves simultaneously to eject the dye liquor from all of the nozzle tips to achieve the highest amount of spray.

Figures 5 and 6 show two different flow nozzle head configurations. When the dye solution enters the nozzle head, it first passes through the dye solution passage port (21) and flows through the nozzle head inlet tube (26) to the chamber I (28). The dye solution passes through the chamber II (29) as it flows from the chamber I to the chamber III (30). The cavity I, the cavity II and the cavity III are all in the shape of a circular tube, but the axis of the pipe of the cavity II does not intersect the axis of the pipe of the cavity III. This design can make the dyeing liquid into turbulent flow when entering the cavity III, and then cooperate with the atomizing shunting block (31) to spray the dyeing liquid from the nozzle head outlet (27) in a mist form. The nozzle head can be designed by changing the cavity I, cavity II, cavity The size of the body III, the atomizing splitter block and the nozzle tip outlet (27) create different amounts of spray. The flow rate of the nozzle tip in Figure 5 is relatively large and the flow rate of the nozzle tip in Figure 6 is relatively small. As shown in Figures 5 and 6, the dyeing passage openings (21) of the two nozzle heads are opposite to the nozzle head body (25) for the purpose of matching the dyeing conduits to which the flow rates belong. The dye solution reaches the nozzle tip outlet (27) through a conduit in the nozzle head body (25).

Figure 7 shows a cross-sectional view of the air flow dyeing machine of the present invention. One or more air filters (32) are mounted in the master cylinder (1) at the bottom of each suction duct (4). When the fan (3) is running, the airflow enters the suction duct through the air filter as shown in the arrow in Fig. 7 to the fan. The air filter blocks the dust in the air and prevents it from damaging the fan structure.

Fig. 8 is a cross-sectional structural view showing the cylinder head of the present invention, and the multi-tube independent air supply dyeing machine of the present invention comprises two or more dye tubes. The fabric is driven by the lifting drum (36) in the cylinder head (2) while circulating in each dyeing tube. The lifting drum is driven by a motor with a gear-like convex portion on the surface of the drum, which can be reduced. The fabric slips when walking on the lifting drum.

Figure 9 shows a specific embodiment of the circuit control system of the air flow dyeing machine of the present invention. The air flow dyeing machine of the present invention has a main computer control (33) for controlling a plurality of independent dye control units (34), each dye tube The control unit independently controls the lifting drum, fan (3), and nozzle assembly (5) of each dye tube.
