Description

Be provided with elastic sealing device's vaporization unit and dyeing machine

Technical Field

The invention relates to the technical field of cloth dyeing, in particular to a steaming unit with an elastic sealing device and a dyeing machine.

Background

As is known, disperse dyes are sublimated into gas under a certain temperature condition, and a considerable part of dye molecules in the traditional thermosol sublimation dyeing process are sublimated and then are not adsorbed in cloth fibers, but volatilize into the atmosphere, so that the problems of low dye utilization rate, light color yield, poor color fastness, equipment pollution and the like exist in the traditional dyeing equipment and dyeing method, reactive dyes need to be subjected to steaming treatment under high-temperature and high-humidity conditions after padding dye liquor or printing, the traditional steaming process is open relative to cloth, moisture carried by the cloth can be gasified and volatilized under a high-temperature state, the humidity of a cloth surface is reduced, and the combination of the dye and the cloth is not facilitated.

In order to solve the problems, a plurality of cloth dyeing and steaming devices are also developed on the market, but the existing steaming devices do not well solve the problem of loss of steam and dye liquor between the heating bull wheel and the conveying belt, the existing devices mainly solve the problem of loss of steam and dye liquor by arranging a baffle bar or a retainer ring at two ends of the heating bull wheel and abutting against the end part of the conveying belt through the baffle bar or the retainer ring, but the conveying belt can shift left and right in the actual production process, and therefore the problem of loss of steam and dye liquor still exists.

In addition, in some existing devices, magnetic powder is mixed in the high-temperature resistant surface layer of the conveying belt, and the magnetic powder is attached to the outer surface of the heating wheel, so that the function of preventing steam from escaping is achieved, but two problems exist, one of which is that: the addition amount of magnetic can not be too big, the life that can influence the conveyer belt too big, its two, the high temperature resistance of general magnetic is not good, surpasss 100 ℃ and just demagnetizes very fast, and the ineffectiveness, vapor and dye liquor under the high temperature condition still can follow the both sides of conveyer belt and escape, and the steam of escape still can drive the unordered migration of dyestuff, and not only extravagant dyestuff still can cause the cloth cover to dye unevenly, influences product quality.

Therefore, in order to solve the technical problems of low dye utilization rate, light color yield of cloth and poor color fastness caused by the dissipation of steam and dye liquor in the conventional steaming equipment, the search for a steaming unit and a dyeing machine with an elastic sealing device and better sealing performance is an important subject researched by the technicians in the field.

the first outlet support wheel 108 is located between the first heating large wheel 103 and the second heating large wheel 203, and the first outlet support wheel 108 is located between the second inlet support wheel 204 and the second inlet pinch wheel 205 or the second heating large wheel 203, or the first outlet support wheel 108 is located beside the second heating large wheel 203 and above the second inlet support wheel 204;

it should be noted that, because the traditional front steaming device and the back steaming device are not closely connected, the two steaming devices need manual auxiliary operation, and because the inside of the equipment is high temperature, usually 130-220 ℃, the operation is not easy for personnel when the cloth is pulled, and in the actual production process, when the tension between the front steaming device and the back steaming device is too small, the phenomenon that the cloth between the front steaming device and the back steaming device falls on the ground often occurs, when the tension is too large, the cloth is easily narrowed and deformed, and even the phenomenon that the cloth joint is broken occurs, which is not favorable for continuous production.

Therefore, the first exit support wheel 108 and the second entrance support wheel 204 are arranged in a staggered manner, i.e. the first exit support wheel 108 is located between the second entrance support wheel 204 and the second entrance pinch wheel 205 (or the second large heating wheel 203).

Furthermore, the elastic gasket is a silica gel sealing ring with a hollow structure, and the section of the elastic gasket is circular or square.

It should be further noted that, when the cloth containing the dye liquor sequentially enters the front-side steaming device and the back-side steaming device, the cloth containing the dye liquor is heated by the first large heating wheel 103 and the second large heating wheel 203, the cloth is located between the first large heating wheel 103 and the first high temperature resistant conveyor belt 102 and between the second large heating wheel 203 and the second high temperature resistant conveyor belt 202 during the heating process, moisture in the dye liquor carried by the cloth is heated to be water vapor, the water vapor respectively exists between the first large heating wheel 103 and the first high temperature resistant conveyor belt 102 and between the second large heating wheel 203 and the second high temperature resistant conveyor belt 202, that is, the periphery of the cloth is high temperature water vapor, and the high temperature water vapor can wet and swell the fibers of the cloth and improve the kinetic energy of fiber molecules, the movement of fiber molecules is accelerated, so that the molecular structure of the fiber is expanded, the molecular gap is increased, and dye molecules can enter the fiber molecular gap. Therefore, by arranging the elastic sealing device 12, the escape of water vapor can be prevented, and when the first heating large wheel 103 and the second large wheel 203 heat the cloth, the disperse dye in the dye solution can realize the effect of changing from a solid state to a sublimation state at high temperature, and the dye molecules after sublimation are coated between the first heating large wheel 103 and the first high-temperature conveyer belt 102 and between the second heating large wheel 203 and the second high-temperature conveyer belt 202, i.e. the water vapor and the dye molecules in the dye solution are locked between the first heating large wheel 103 and the first high-temperature conveyer belt 102 and between the second heating large wheel 203 and the second high-temperature conveyer belt 202, so that by arranging the elastic sealing device 12, the escape of the dye molecules after sublimation can be prevented without volatilizing into the atmosphere, and the dye molecules are in close contact with the cloth fiber molecules during the whole heating process, the dye molecules are fully mixed in high-temperature water vapor in the whole heating process, and under the medium action of high-temperature water molecules, the dye molecules can more easily enter fiber molecule gaps, so that the cloth fibers can better adsorb and accept the dye molecules, the dye utilization rate is higher, the color yield is higher, the color fastness is higher, the surface flooding of the cloth is less, the subsequent washing load is reduced, and the sewage discharge amount is less.

It should be noted that, the fabric front steaming device 1 and the fabric back steaming device 2 can both perform integral dyeing on the fabric, and the difference is that in the fabric front steaming device 1, because the front of the fabric is in contact with the first heating large wheel 103, the kinetic energy of the front of the fabric is larger, and the adsorbed dye is more, that is, the front color yield of the fabric is deeper, and similarly, in the fabric back steaming device 2, the back color yield of the fabric is deeper, and by arranging the fabric front steaming device 1 and the fabric back steaming device 2, the problem of color difference between the front and the back of the fabric can be solved, so that the dyeing effects of the front and the back of the fabric are more consistent, the color difference is smaller, and the quality is better.

In practical application, since the fabric front side steaming device 1 contacts the dye first, the dye is relatively difficult to migrate to the back side of the fabric in a subsequent process after being combined with the front side of the fabric, and therefore, the diameter (or the effective working area length) of the first heating guide wheel 102 is preferably smaller than the diameter (or the effective working area length) of the second heating guide wheel 202, for example, the diameter of the first heating guide wheel 102 is 1200mm, and the diameter of the second heating guide wheel 202 is 1500 mm. Alternatively, the surface working temperature of first heated idler 102 is set to be slightly lower than the surface working temperature of second heated idler 202, for example, the surface working temperature of first heated idler 102 is set to 180 ℃, and the surface working temperature of second heated idler 202 is set to 185 ℃

Of course, there are still situations in which dye molecules are bound to fiber molecules by so-called van der waals forces and hydrogen bonding during operation and enter the interior of the molecular structure of the fiber. In the whole heating process of the cloth, dye molecules are fully mixed in high-temperature water vapor, and under the medium action of water molecules, the dye molecules can more easily enter gaps among fiber molecules through repeated rolling of the pressing wheel, so that the cloth fibers can adsorb and accept the dye molecules as much as possible, and therefore, the method disclosed by the invention is high in dye utilization rate and deeper in color yield. The invention increases the utilization rate of the dye in a physical mode, can reduce or eliminate the dye auxiliary agent of the traditional dyeing, and is beneficial to environmental protection. Because the dye molecules are completely adsorbed, the dyed cloth basically does not need to be washed by water, and if the finished product with extremely high requirements still needs to be washed by water, the water consumption in the washing process is greatly reduced, thereby being very beneficial to environmental protection. After the heating process is finished, the dye molecules are tightly combined with the fiber molecules through natural cooling or air cooling or cooling by a cooling wheel, the dye particles are fixed in the fiber of the cloth and are sent to a cloth dropping frame or rolled into a finished product through a rolling device, and compared with the traditional cloth dyeing equipment, the double-sided steaming device is high in dye utilization rate and better in color fastness.

Further, a first blowing device 107 and/or a second blowing device 207 are/is further included;

the first blowing device 107 is arranged between the first heating large wheel 103 and the second inlet support wheel 204, and the first blowing device 107 faces the first outlet support wheel 108;

the second blowing device 207 is disposed between the second heating large wheel 203 and the first exit support wheel 108 or the first support wheel 106, and the second blowing device 207 faces the second entrance pinch wheel 205.

It should be noted that, with the above design, when the fabric is transited from the fabric front side steaming device 1 to the back side steaming device, the fabric may adhere to the surface of the first heating large wheel 103 or the first high temperature resistant conveying belt 102 and may not enter the fabric back side steaming device 2, at this time, the first blowing device 107 and/or the second blowing device 207 blows the fabric adhered to the surface of the first heating large wheel 103 or the first high temperature resistant conveying belt 102, so that the fabric may be separated from the first heating large wheel 103 or the first high temperature resistant conveying belt 102 and enter between the second high temperature resistant conveying belt 202 or the second heating large wheel 203, and thus automatically enter the back side steaming device 2, and manual material pulling operation under a high temperature environment is avoided.

The blowing device is a spray gun or an air pipe connected with an air compressor or an air blower, preferably, the air pipe is arranged along the width direction of the roller surface of the heating large wheel, and a plurality of air outlets are arranged in the radial direction of the air pipe.

Further, the outer circular surface of the first heating large wheel 103 and the outer circular surface of the second heating large wheel 203 are both surfaces with uniformly distributed concave points or concave lines formed by corrosion, electric carving, laser carving, mold pressing process or sand blasting treatment.

It should be noted that, in order to avoid the solution adhering to the heated large wheel, electroplating, polishing or spraying teflon on the surface of the heated large wheel is usually performed to make the surface of the heated large wheel as smooth as possible, but the smooth surface may aggravate the migration of the steam or dye solution along the smooth surface, which may cause quality problems. Tests show that the uniformly distributed pits (or uniformly rough surfaces) can effectively block the migration phenomenon of steam (or dye solution).

Meanwhile, the surface of the heating large wheel in the general sense is smooth, and after the cloth is heated at the high temperature of the heating large wheel, the surface of the cloth generates a bright ironing effect, so that the original style of the cloth is lost.

Therefore, the outer circular surface of the first heating bull wheel 103 and the outer circular surface of the second heating bull wheel 203 in the embodiment are uniformly distributed concave surfaces formed by corrosion, electric carving, laser carving, die pressing process or sand blasting, and the migration phenomenon of the dye solution can be effectively avoided because the concave points are separated by lines; meanwhile, the concave parts of the concave points can not contact with the cloth, and only the protruding parts contact with the cloth, so the uniformly distributed concave points (or concave lines) can effectively avoid the polished surface effect after processing, and the original style of the cloth can be well maintained.

The mesh number of the pits is preferably 30 to 300 mesh, and more preferably 100 mesh.

Further, the cloth front steaming device 1 and the cloth back steaming device 2 are arranged in front and back in the horizontal direction, the first supporting wheel 106 group further includes a first guiding supporting wheel 109, and the first guiding supporting wheel 109 is arranged between the first outlet supporting wheel 108 and the second heating large wheel 203 and is close to the second heating large wheel 203 and the second inlet pressing wheel 205.

It should be noted that, with the above design, when the fabric is transited from the fabric front side steaming device 1 to the fabric back side steaming device 2, the fabric will automatically separate from the first heating large wheel 103 or the first high temperature resistant conveying belt 102 under the action of gravity, and enter the fabric back side steaming device 2 under the clamping of the first high temperature resistant conveying belt 102 and the second high temperature resistant conveying belt 202, so as to avoid manual material pulling operation in a high temperature environment.

Further, in order to provide a suitable tension to prevent the first high temperature conveyor belt from deviating from the first heating large wheel 103 and the second high temperature resistant conveyor belt 202 from deviating from the second heating large wheel 203, for example, the cloth front steaming device 1 and the cloth back steaming device 2 are respectively provided with a deviation rectifying device, the deviation rectifying devices are arranged adjacent to the cloth front steaming device 1 and the cloth back steaming device 2, the deviation rectifying devices comprise a deviation rectifying sensor, a deviation rectifying power device and a plurality of deviation rectifying wheels, each deviation rectifying wheel is respectively used for sleeving the high temperature resistant conveyor belts, the deviation rectifying wheels are rotatably fixed on the frame, one end of each deviation rectifying wheel can swing with the other end as the center, the sensor detects the edge condition of the conveyor belt, and controls the swing of the deviation rectifying wheels through detection signals, so that the conveying belt is guided passively to achieve the purpose of deviation rectification;

for another example, the two or more steaming units continuously heat the front and back sides of the fabric, so that the dyeing effects of the front and back sides of the fabric are more consistent. Two or more groups of the steaming units are provided with a heating large wheel, a high-temperature resistant conveying belt coated outside the heating large wheel, a supporting wheel and a deviation correcting device, so that a proper tension force can be provided to prevent the first high-temperature conveying belt from deviating from the first heating large wheel 103 and prevent the second high-temperature conveying belt from deviating from the second heating large wheel 203.

Further, in order to improve the high temperature resistance of the high temperature resistant conveyor belt and make it difficult to adsorb dye molecules, for example, the first high temperature resistant conveyor belt 102 and the second high temperature resistant conveyor belt 202 both include a conveyor belt body and a high temperature resistant layer adhered on the surface of the conveyor belt, the material of the high temperature resistant layer is teflon (Polytetrafluoroethylene), and the conveyor belt body is formed by weaving wool blend fiber, kevlar fiber or aromatic polyamide fiber; for another example, the high-temperature resistant conveying belt is an annular silica gel conveying belt; for another example, the base band of the endless conveyor belt is made of a material which is capable of resisting high temperature and is not easy to adsorb dye molecules, such as wool blend, dupont KEVLAR fiber, or meta-aromatic polyamide fiber (Nomex), so that the high temperature resistance of the high temperature resistant conveyor belt can be improved, and the dye molecules are not easy to adsorb. For example, the high temperature resistant conveyer belt not only needs to be resistant to high temperature, but also needs to be made of a material which is not easy to absorb dye molecules, and the material of the working surface of the first high temperature resistant conveyer belt is a material which can resist high temperature and is not easy to absorb dye molecules, such as silica gel, teflon, wool blend, dupont KEVLAR fiber, meta-position aromatic polyamide fiber (Nomex), stainless steel and the like.
