Description

Conveyor belt dyeing machine with cloth head detecting device

The present invention relates to a conveyor belt dyeing machine capable of monitoring and recording the operation of the cloth, detecting the number of times of the cloth cycle, and controlling the dyeing process.

The first figure is a schematic diagram showing the dyeing cycle of the cloth of the conventional rope dyeing machine. The principle is that the dye solution F is pressurized via the pump D2 and enters the nozzle A4 via the heat exchanger C (heating or cooling) to generate the jet or overflow water flow force, and then returns to the accumulation tank A1 of the dyeing machine A, and the cloth B is driven by the guide wheel A3 (or without the guide wheel) into the nozzle A4, and the cloth B is circulated by the jet or overflow force of the nozzle A4, and the dye and the auxiliary agent are pressurized by the auxiliary tank E via the pump D1. Injecting into the dyeing machine A, the dyeing liquid F and the cloth B are heated in the circulation and heat-cooled through the heat exchanger C to absorb the dye by the cloth to achieve the refining, dyeing and water washing effects; and the uniformity of dyeing (smoothing) ), depending on the number of cycles of the cloth during the dyeing process, that is, the number of times the cloth B interacts with the dye solution between the nozzle A4 and the dyeing tube A2. The more the number of cycles, the more interactions are made, so the more uniform the dyeing, the same the degree of washing and the same fastness.

With reference to the graph of the dyeing process of the conventional rope dyeing machine of the second figure, the conventional dyeing machine uses the time as the control unit (denominator) regardless of the theory or practice to add the medicine to the cloth → warming → heat preservation → warming → heat preservation → cooling → washing → dosing → heating → heat preservation → cooling → hot water washing process; and its control method is to use computer or program numerical control (PLC) Wait for controller control.

Because the dyeing method of the conventional rope dyeing machine is based on time, the dyeing process needs the same time regardless of the actual amount of dyeing, but the actual dyeing amount is different due to the weight or the thickness of the cloth. The length of the cloth in each cylinder, tube or slot of the dyeing machine is different, so the cloth is the same, but if the same dyeing time is used, it will not only waste time, but also the cloth in the whole dyeing process, because of each cylinder or tube The actual amount of dyeing cloth (length and length) is different, so that the actual number of cycles of the cloth is different. Therefore, the dyeing time is the same but the degree of dyeing is different. On the contrary, problems such as tube difference or cylinder difference, inconsistent fastness, and poor reproducibility are caused. It causes heavy dyeing and poor production quality and efficiency, a lot of waste of energy and labor costs and environmental pollution... This reproducible problem is a problem that dyeing factories have faced for a long time and is difficult to overcome.

The purpose of this creation is to solve the dyeing processing method of the conventional rope dyeing machine, which is controlled by time, so that the dyeing process is performed at the same time regardless of the actual length of the dyed fabric, so that the dyeing time is the same, The degree of dyeing is not the same, but it causes problems such as tube difference or cylinder difference, inconsistent fastness, poor reproducibility, and wasted time.

In order to solve this problem, this creation changes the control mode of the traditional dyeing machine. The number of cloth cycles is changed to the control unit (denominator), and the horizontal coordinate "time" of the graph shown in the second figure is changed to "" The number of times the cloth is cycled, so that regardless of the actual length of the cloth, the dyeing process is controlled by the number of times of the cloth, that is, the overall dyeing time is longer when the cloth is longer, and the dyeing time can be relatively shorter when the cloth is shorter. It is shorter; because the number of cycles of each dyeing tube or batch is the same in the whole dyeing process, the degree of application and the degree of washing are the same, so that zero tube difference or zero cylinder difference and fastness can be ensured. 100% reproducibility, greatly improving raw products Quality and efficiency, and significantly reduce production costs and energy conservation and carbon reduction to promote environmental protection.

The technical means of the creation is to provide a conveyor belt device in the body of the rope dyeing machine for transporting the cloth circulating in the body of the dyeing machine from the tail of the body to the front end without using the traditional dyeing machine. Water flow or aerodynamic push, and the speed control of the conveyor belt is controlled by a controller such as a computer or a program controller (PLC) to synchronize with the cycle speed of the cloth, and the speed can be adjusted at any time, but once set, it is a constant speed motion. , that is, the circulation speed of the cloth is stable and constant speed, so the cycle time is the same every time. This creation is based on this certain speed characteristic, and the cloth head detecting device is set at an appropriate position in the conveyor belt or the dyeing machine, and the cloth head detecting device is used. The signal is sent through the controller such as a computer or a program controller (PLC), and the number of cloth cycles is used as the control unit of the dyeing process. This ensures that the dyeing time, colorlessness, no cylinder difference, and fastness are shortened as described above. Consistent, 100% reproducibility, and can improve product quality, improve production efficiency, reduce production costs, save energy and reduce carbon, and promote environmental protection.

The advantages of this creation include:

First, the dyeing process time is shortened due to the decrease in the length of the dyed fabric.

Second, regardless of the length of the actual amount of dyed cloth, the number of cycles of the cloth is the same, the degree of dyeing is the same, so the dyeing reproducibility is 100%, no problems such as poor tube difference, cylinder difference and fastness.

Third, regardless of the actual amount of dyeing, the number of cycles is the same, the cloth surface and the dyeing machine contact (friction and stretching) the same number of times, so the quality of the cloth surface is consistent.

The first figure is a schematic diagram showing the dyeing cycle of the cloth of the conventional rope dyeing machine; the second figure is a graph showing the dyeing process of the conventional rope dyeing machine; The third figure is a schematic view showing the conveyor belt type dyeing machine with the cloth head detecting device of the present creation; and the fourth figure is a graph showing the dyeing process of the present rope dyeing machine.

The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present invention after reading this specification.

As shown in the third figure, the dyeing machine with the cloth head detecting device provided by the present invention mainly has a conveyor belt device 2 disposed in the body 1, so that the cloth 3 is transported from the rear of the body 1 to the front end, and the cloth 3 is passed through The cloth guide wheel 4 drives into the nozzle 5, and the dyeing liquid 6 is pressurized by the pump 7 through the heat exchanger 8 to control the temperature, and then sprayed by the nozzle 5 to produce a dyeing effect on the cloth, and drives the cloth 3 into the guide tube and then falls into the cloth. The conveyor belt device 2 is transported to the front end of the body so as to form an annular cyclic motion for the dyeing process, and the effect of the dyeing depends on the number of times the cloth interacts with the dye liquor at the nozzle.

The operating speed of the conveyor belt device 2 described above is controlled by the control box 9 so as to be synchronized with the cycle speed of the cloth, and the speed can be arbitrarily adjusted, but once set, the speed is constant and the constant speed, that is, the circulation speed of the cloth is fixed. The cycle time is also the same every time, and the dyeing process (referred to as "dyeing process") is based on the number of times of the cloth cycle detected by the cloth head detector 10, and is controlled by the computer or program controller (PLC) of the control box 9. The controller controls to perform the dyeing process as shown in the fourth figure.

It can be seen from the above that the actual dyeing effect of the belt-type dyeing machine with the cloth head detecting device is mainly determined directly by the number of times the cloth interacts with the dyeing liquid at the nozzle, that is, the number of times the cloth is cycled rather than the length of time (also That is, it has an absolute relationship with the number of cycles, but only has a relative relationship with time.) Therefore, if the speed of each tube or cylinder of the dyeing machine is the same, if the time is the same, The longer the actual length of the dyed fabric, the less the number of cycles in the dyeing process, and the shorter the length of the dyed fabric, the more the number of cycles. Therefore, although the time is the same, but the degree of dyeing is different, the dyeing effect is different, resulting in problems such as tube difference, cylinder difference, fastness, and inconsistency. Therefore, the same dyeing effect, regardless of the length of the dyed fabric, the number of cycles should be The same, that is, the shorter length of the cloth, the time can be relatively shortened, so not only can shorten the entire dyeing process time, and because the length of the cloth is the same regardless of the length of the cloth, the degree of application is the same, which can ensure the 100% reproducibility of dyeing, without A tube difference or cylinder difference and fastness are generated and need to be re-dyed.

The above is only a preferred embodiment for explaining the present invention, and is not intended to impose any form of restriction on the present creation, so that any modifications or changes to the creation made in the same creative spirit are made. , should still be included in the scope of protection of this creative intent.
