Description

Towel dyeing machine

The invention relates to a dyeing and finishing device, in particular to a towel dyeing machine. Say

Background technique

In the field of dyeing and finishing technology, increasing the time in which the fabric is in contact with the dyeing liquid is a necessary condition for ensuring coloring. However, under the current environmental protection emission reduction regulations, the new dyeing machine uses a nozzle to concentrate the dye solution on the circulating walking fabric. The fabric is generally circulated in the dyeing machine in the shape of a rope and scattered.

In the storage tank, the rope is pulled up by the lifting roller and guided to the nozzle throat, sprayed by the dyeing liquid and then returned to the storage tank, so that the circulation is repeated, so that the entire piece of the head-to-tail cloth is repeatedly contacted with the dyeing liquid. color. A dyeing machine arrangement with a double drum is disclosed in the patent document of the patent number CN1271271C. The patent is characterized by a pair of nozzle assemblies between the two rollers that spray the dye liquor onto the running fabric. The dye solution falling into the storage tank is collected at the bottom of the tank and returned to the nozzle for recycling to form a dead loop. Although the design reduces the amount of dyeing liquid, the coloring efficiency is always significantly different from the traditional bathing dyeing, and it is impossible to take into account both the low bath ratio and the coloring efficiency.

In addition, fabric dyeing machines developed in the prior art generally focus on finishing lightweight materials and materials that are sensitive to wrinkles, while reducing the finishing of heavy fabrics such as terry cloth. The existing dyeing and finishing machine technology generally lifts the fabric to the nozzle throat at the top of the master cylinder. The dye liquor is directly sprayed onto the surface of the fabric to spread, and the dye liquor can be evenly spread in the light weight fabric, but the heavy fabric is due to its own weight. So that the fabric can't be blown off by the dyeing liquid like the light weight fabric, the light weight of the fabric can not reach the uniformity of the dyeing liquid, and the heavy weight of the fabric must be treated with more water to match the movement of the cloth. Increased water and electricity consumption.

Summary of the invention

The present invention solves the above technical problems and adopts a novel design.

The towel dyeing machine of the present invention comprises a dyeing machine main casing (1), a dyeing bottom tank (10), a lifting drum (3), a secondary lifting drum (4) and an arranging device, and the towel dyeing machine is further provided with a dyeing assistant. Slot (6). The dyeing auxiliary tank (6) is installed above the dyeing bottom tank (10) between the lifting drum (3) and the auxiliary lifting drum (4), and the fabric that travels between the two rollers (3) and (4) falls into the fabric. In the dyeing auxiliary tank (6), the passive roller (5) is installed in the dyeing auxiliary tank, and is installed in parallel with the rollers (3) and (4), and the fabric passes through the dyeing auxiliary groove under the passive roller (5);

A row of nozzles consisting of two or more (including two) nozzles (11) is laterally mounted on the inner wall of the bottom of the dyeing sub-tank (6) to connect the source of the dye solution.

The dyeing sub-tank achieves the dyeing and finishing effect by means of gushing and dip dyeing. The dyeing auxiliary tank is equipped with a smooth roller with a smooth surface to press the fabric into the dye bath to color, ensuring that the fabric passes through the dyeing sub-tank in the circulation. The bottom of the dyeing sub-tank is connected to a plurality of nozzle throats, and the nozzle throat is blown out from the bottom to the top, and has the function of preventing the hair and the dye liquor from uniformly spreading on the fabric. The dyeing auxiliary tank runs in full load of dyeing liquid, and the dyeing liquid is pumped from the bottom of the storage tank through the main pump to the nozzle of the dyeing auxiliary tank, so that the dyeing auxiliary tank holds a certain amount of dyeing liquid into a dyeing tank when the apparatus is in operation. . The dyeing sub-tank is placed in the center of the dyeing machine, and the volume is smaller than the bottom tank, which helps to reduce the amount of dye liquor.

The surface of the towel fabric has a smooth surface that will move with the flow of the dye solution. If the towel is turbulent when it comes into contact with the dye solution, it will result in uneven coloring of the hair, which will eventually affect the color after dyeing. In the present invention, the dyeing liquid emerges from a row of flat nozzles at the bottom of the dyeing sub-tank to ensure the singularity of the fine hair direction of the fabric surface. By injecting the dye solution into the dyeing sub tank filled with the dye solution, it is possible to ensure that the dye liquor has the same concentration in the dyeing sub tank. Therefore, the technique of the present invention can focus on solving the quality problem of heavy fabrics such as dyed towels.

In the towel dyeing machine of the present invention, the cross section of the bottom of the dyeing sub-tank (6) is curved, and the inclination angle formed by the entrance of the dyeing sub-tank (6) and the horizontal is larger than the inclination angle of the exit of the dyeing sub-tank. The angle of inclination is less than 90 degrees. At the entrance, as shown in the drawing, the dyed fabric enters the entrance of the dyed sub-tank (6).

The slope in front of the dyeing sub-tank is higher than the rear, and the weight of the fabric itself is concentrated on the bottom of the dyeing sub-tank to reduce the pulling force required to lift the drum.

In the towel dyeing machine of the present invention, the dyeing auxiliary tank (6) is smaller in volume than the bottom tank, and the dyeing auxiliary tank (6) is provided with a drum (5), and the surface of the drum is smooth.

The towel dyeing machine of the present invention is provided with a sensor (13) at the entrance of the dyeing sub-tank (6). The fabric passes through a plurality of rollers in the dyeing machine, and the pulling between the rollers increases the surface tension of the cloth. If the tension is too large, there is a chance to damage the cloth. Therefore, the device of the present invention has a sensor to monitor the traveling of the cloth between the rollers, and appropriately adjust each part or part. The rotation speed of the drum to control the tension of the cloth. In the towel dyeing machine of the present invention, the nozzle (11) is connected to the nozzle throat (7) and has an elliptical shape.

The duckbill-shaped nozzle assembled by the dyeing sub-tank causes the dyeing liquid to be sprayed to the dyeing auxiliary tank at a high-speed and high-pressure, neutralizing the high-concentration dyeing liquid, and the direction of the fineness of the fabric surface is uniform due to the uniform direction of the jetting.

The dyed fabric passes through the flat nozzle of the dyeing sub-tank, and passes through the smooth roller of the dyeing auxiliary groove in a narrow and wide form. The narrowing helps the flat nozzle to make the fine hair on the surface of the textile uniform in the same direction; the widening is beneficial to prevent dyeing wrinkles, creases and uneven color of the fabric when dyeing the dyeing liquid in the dyeing auxiliary tank. The dyeing liquid is pumped from the bottom of the storage tank through the main pump to the nozzle of the dyeing auxiliary tank, and the dyeing liquid in the dyeing sub-tank is fully filled when the device is in operation.

In the towel dyeing machine of the present invention, the swinging device is constituted by a guide sheet (18) provided at the entrance of the dyeing bottom groove (6).

The guide cloth is placed in the space above the storage tank after the fabric passes through the auxiliary lifting drum, and extends laterally between the opposite side walls of the storage tank. The guide cloth is a board that can swing up and down, and the amplitude of the up and down swing is placed in one. The position between the innermost position and the rear wall of the storage tank is predetermined. This illuminating device is connected to a separate adjustable speed motor to change the yaw frequency. The arranging device serves to systematically stack the woven fabric fed from the rear drum to the bottom of the storage tank.

Since the present invention is primarily directed to dyeing and weaving heavy textiles, the swash plate of the device behind the machine can be provided with a coating of low friction material. This can effectively reduce the friction between the pendulum plate and the fabric during operation, so that the fabric can be easily guided through the pendulum plate and introduced into the storage trough below.

In the towel dyeing machine of the present invention, the lift roller (3) and the secondary lift roller (4) are connected to a control system.

In the present invention, each of the lifting drum and the auxiliary lifting drum is controlled by an independent motor, and the rotation speed of the specific fabric can be freely selected to make the fabric cycle smoothly, reduce the chance of slippage between the cloth and the drum, and reduce the friction caused by friction. The impact of quality decline.

In the towel dyeing machine of the present invention, the surfaces of the lifting roller (3) and the secondary lifting roller (4) are non-smoothly corrugated.

The undulating surface texture increases the static friction between the drum and the fabric, reducing the chance of slippage and protecting the fabric from wear.

In the towel dyeing machine of the present invention, the dyeing machine main casing (1) is provided with a maintenance door (12). The towel dyeing machine device of the present invention has a work door (2) and a service door (12), the work door Located in front of the machine, the service door is located on the top of the machine.

The invention will now be further elucidated with reference to the drawings and embodiments of the invention.

The structure of the towel dyeing machine of this embodiment is shown in a partial cross-sectional view of Fig. 1. The embodiment comprises a main casing 1 of a dyeing machine, a working door 2 is arranged on the front side of the dyeing machine, and a lifting drum 3 and a secondary lifting drum 4 are arranged in the dyeing machine, and a dyeing auxiliary groove 6 is arranged between the two rollers. There is a passive roller 5 inside, and the fabric entering the auxiliary groove passes under the passive roller. The bottom of the auxiliary tank is connected to a row of nozzle throats 7, and the dye liquor in the dyeing machine is sprayed onto the fabric. There is also a partition 8 in the dyeing machine to separate the dyeing sub-tank and the bottom storage tank 10 to prevent the cloth 9 from falling into the storage tank and causing entanglement when the sub-tank is overloaded. There are perforations in the partition to allow the dye solution to flow into the storage tank.

This embodiment is provided with an arranging device which is constituted by a guide sheet 18 provided at the entrance of the dyeing bottom groove 10.

This embodiment is dyed in the form of a wet treatment circulating cloth. The fabric passes through the lifting drum and then to the dyeing sub-tank for dyeing. The secondary lifting roller then pulls the fabric out of the intermediate cloth groove. The fabric passes through the secondary lifting drum and then to the guide cloth, and then returns to the lower storage tank.

The dyeing liquid in the dyeing machine is dyed on the cloth by means of circulating spraying. The dye liquid flowing into the bottom of the dyeing machine is collected in the bottom tank 15 and pumped away by the main circulation pump 16, and a filter 17 is placed in front of the main circulation pump inlet to protect the pump from the dust discharged from the dyeing machine. The main circulation pump provides power to pump the dye from the bottom of the fuselage back to the top of the machine. The dye solution returns to the nozzle throat through the throat and is applied to the cloth again. Fig. 2 is a perspective view showing an embodiment of the present invention, and the throat arrangement of the dyeing machine is as shown in Fig. 3. Fig. 3 is a schematic view showing the flow direction of the dyeing liquid of the sub-tank nozzle of the present invention. The nozzle throat 7 is installed between the auxiliary groove 6 and the partition plate 8, and a row of flat nozzles 11 are horizontally arranged at the bottom of the auxiliary groove, and the nozzle throat is connected to introduce the dye liquor from the nozzle throat into the auxiliary groove. The shape of the flat nozzle is elliptical, the port connecting the auxiliary groove is substantially directed to the passive roller 5, and the longer elliptical end is directed to both sides of the fuselage, so that the liquid flow can laterally disperse its impact force when the dye liquor is ejected from the flat nozzle outlet, Provides additional support for the fabric in the secondary tank, helping the fabric to adhere to the passive roller, reducing entanglement.

The sensor 13 is mounted at the entrance of the dyeing sub-tank, near the edge of its curved bottom plate. Pass The sensor is connected to the control system of the dyeing machine. When the sensor touches the cloth and sends a signal, the system controls the connected lift roller motor and the secondary lift roller motor to adjust the rotation speed.

Figure 4 is a flow chart showing the control signal processing of the drum rotation speed. The operation of the drum control using the sensing device on the auxiliary slot and the main control system of the dyeing machine is as follows:

Step 1: The dyeing machine performs initial setting after the drum control function is started, for example, clearing all the drum speeds and timers;

Step 2: Set the lifting drum to run at a slower speed;

Step 3: Start the timer, and at the same time, monitor whether the controller receives the indication of the outage during the timing. This condition is often set manually, and if the indication is received, the automatic control of the drum is ended;

Step 4: After the timer has exceeded a limited time, the lifting drum starts to run at a faster standard speed and is re-timed. When the lifting drum runs at a faster speed than the auxiliary lifting drum, the cloth in the auxiliary groove will increase accordingly;

Step 5: When the sensor touches the cloth that is nearly overflowing from the sub-tank, return to the second step to run at a slower speed, and the timer is cleared at the same time. Even if the sub-slot is never overloaded so that the sensor never touches the cloth, the timer will automatically slow down after exceeding a limit time value. In this step, the controller can still monitor the signal of the outage, as in the third step;

Step 6. The dyeing machine controller runs the drum speed of the fifth step for a predetermined period of time, and then monitors whether the signal of the sensor still indicates an overload. If the sub-slot is still overloaded, repeat this step for another period of time until the overload signal is canceled, then return to step four, and the timer is cleared at the same time, and so on. Similarly, this step can be performed at any time.
