Description

Technical field

In particular, the invention relates to innovation in machines for continuous processing of various processes such as dyeing, bleaching or washing, which are used in industrial processes related to fabric production.
More particularly, the invention relates to novelty in exhaust based jet textile dyeing machines for conveying the rotational force to the drum in the tower body, which enables the fabric to be conveyed to the fabric chamber known as J-box, where the fabric is maintained and which is the area where the dyeing takes place.

State of the Art

The machines of the prior art for such fabrics are in a loop through a tower which includes a motor driven drum, which can be rotated about the rotation axis of the process, enabling the continuous circulation of the fabric as shown in Figures 16, 17, 18 and 19. The fabric descends into the bath by means of the nozzle and the drum, and then it is taken from the bath by the drum and continued on its tour.
The nozzle is the part where the fabric and the solution connect and both move together. The nozzle both provides both the circulation of the solution and the transport of the fabric.
The actual movement of the fabric is with the solution sprayed from the nozzle and the drum inside the tower supports it.
The fabric which is pushed from the nozzle with the solution through the fabric pipe and comes into the section which is called J-box in the form of O or J and which is located in the body, and waits in the bath for other tours. Then it continues the tour in the fabric machine by means of the drum.
In the present technique, the drum is kept completely closed in the tower body with the housing elements as it is seen in the Figure 17.
There should be no liquid and pressure loss in order to make a healthy operation in fabric dye machines. It is necessary to transfer the drive from the motor to the drum located in the tower body.
For this purpose, the drum is positioned within the tower body in the present technique, which is shown in detail in Figures 18 and 19 in detail. The drum provides connection with the packing seat and the pulley. The rotating movement transferred from the motor to the pulley by means of a belt is conveyed to the drum by means of the roller bearing and the shaft to turn the drum. In order to prevent leakage and dropping, the mechanical packing is located on the shaft connected to the packing seat.
Mechanical packing is a sealing element in systems that rotate at least one half turn systems, especially preventing loss of values such as fluid, pressure, temperature.
The fixed element of the packings is located on the housing and the rotary element is located on the shaft. In this way, it limits leakage, provides leak-tight control.
In the present technique, the movement to the drum is provided by motor using the belt, pulley, bearing and shaft, and the pulley is closed by the belt casing.
Sealing is ensured by means of the mechanical packing located on the transfer shaft.
In this case, the existing packings are moving parts and they are deformed due to wear and movement. This failure depends on the machine size and the working time, though certainly happens between 6 months and 1 year.
In case of malfunction, it can be intervened by technical service and can be changed after 3 hours of operation.
During the change, the machine is unavailable and production is stopped.
More important is that the entire fabric in operation within the machine becomes waste if it fails during the process. The fabric, which is treated in the bath, is unable to complete its circulation due to the seal failure and it is necessary to recover it by recycling.
At the same time, the excess of the intermediate parts used for conveying the movement to the drum has a great effect on production costs, and it has become necessary to make an improvement considering the installation labor costs and engine power losses.
Particularly in the fabric dye machines, the packings are the most failed parts. Considering the costs and the damage caused, it can cause very high costs to the manufacturer. At the same time the necessity of dismantling the closed tower and having to re-constitute the assembly for the change operation can cause considerable time and labor costs.
As a result, the applicant has seen the need to demonstrate power transmission with lower costs in order to achieve the drum movement.
In this context, the technical aim of the present invention is to provide a machine which enables the transmission of power with less parts and less energy in the same effect to the drum, which in turn rotates in its axis and circulates the fabric within the tower.
At the same time, it aims to provide a solution that increases the technical characteristics of the drum, which allows the tower to be made more uniform. At the same time, it aims to turn the enclosed tower into a more insulated environment.

Detailed description of the invention

The invention is a transmission mechanism (100), which transmits rotation force from a motor (108) to a drum (101) located inside a tower body (21) in a fabric dyeing machine (1), having at least one housing (14) located inside a main body (10) which enables fluid bath, at least one tower (20) located over each housing (14) wherein its main fluid tank is located inside the main body (10), at least one drum (101) which is located on each tower (20) and supporting and directing the related fabric through its continuous circulation inside the closed circuit in the housing (14), at least one nozzle (11) which is located close to each drum (101), pushing fluid on the fabric, a liquid pipe (13) wherein one of its end is connected to a suction pipe (16) located under the housing (14), which is the main part of the bottom area of the main body (10), and its other end is connected to the nozzle (11), providing liquid circulation via a pump located on it, at least one outlet pipe (17), which is located at each housing (14), providing continuous fabric circulation, connected to the tower body (21) where the drum (101) is located.
The fabric (15) dyeing machine (1) includes a main tank designed to receive the dye required for dyeing for example an x length fabric (15), within the volume separated within the main body (10). The liquid forms a bath by filling the bottom of the housing (14) formed in the main body (10). At the same time, the filled liquid circulates in the machine (1) by the liquid pipe (13) and the pump.
On the upper part of the machine (1), there are p.t drums (28), which rotate in their own axis driven by the motor (108), equal to the number of the housings (14) formed in the main body (10). P.t drums (28) are located within the tower (20).
The p.t drums (28) formed in each tower (20) and provided according to the number of the housings (14) support and guide the advance of the fabric (15) along the closed process path. The p.t drums (28) are located on the tower (20) in the main body (10) in a closed manner. As shown in Figure 16b, the fabric (15) proceeds from the drum (101) located in the tower (20) into the housing (14) following the fabric pipe (12) with the effect of the fluid being pressed from the nozzle (11). Following an outlet pipe (17) from the bath formed under the housing (14), it goes back to the p.t drum (28).
In this way, the fabric (15) is treated by continuing the circulation in the main body (10).
From the bath formed at the bottom of the main body (10) and the housing (14), the liquid is drawn by means of the pump through the liquid pipe (13) to the nozzle (11) and the cycle of the liquid is provided. The nozzle (11) ensures that the fabric (15) is wetted and progressed before being immersed in the bath in the housing (14).
At this time, the e.t drum (28) assists the process, while at the same time allowing the fabric (15) to move in the desired direction and to recirculate coming from the outlet pipe (17).
For this purpose, the motor (108) is connected to the tower body (21) and movement is transmitted to the pulley (24) by the belt (23). Figures 18 and 19 show a representative view of the prior art. In this manner, the movement transmitted to the pulley (24) is transmitted to the p.t drum (28) via the bearing housing (27) and the shaft.
The mechanical seal (25) is used because it is necessary to close the drum (28) located in the tower (20).
In the present technique, the power generated at the motor (108) is transferred to the drum (101) by the belt (23), the pulley (24), the packing (25), the packing seat (26) and the bearing housing (27).
The most important of these parts the mechanical seal (25), which is the basis of the invention, and fails at certain intervals in the previous technique, resulting in large material losses.
In the application of the tower (20), which is the subject of the invention and seen in Figure 1, the power obtained from the motor (108) is transmitted via a drive unit (107). The existing belt (23), the pulley (24), the packing (25), the packing seat (26) and the bearing housing (27) are eliminated.
The p.t drum (28) has been revised and adapted to the new system. The side surfaces were closed and transformed into a design that would allow the system to operate.
The drive unit (107), comprising a motor (108), a drive shaft (110), a drive mirror (111), a sealing flange (112), a mounting flange (113) and an extension flange (114) provides installation to a body slot (21.1) formed on the tower body (21) as shown in Figure 4. This facilitates mounting of the drive unit (107). Assembling, disassembling and access inside the tower (20) is facilitated. Labor and installation costs are reduced.
The mechanism (100) according to the invention is in its most basic shape in the form of Figures 5 and 6. The drum (101) is formed by pipes (102) positioned between the front mirror (104) and the rear mirror (105). The drum shaft (103) is connected to the front mirror (104) and the rear mirror (105) through the slots formed in their centers. The drum shaft (103) is driven by the front mirror (104). With the movement of the front mirror (104), the rear mirror (105) and the entire drum (101) are rotated.
The pipes (102) provide better transmission of the fabric (15) compared to the applications of the current art, but also the ease of modification, if damaged. The pipes (102) are the areas in contact with the fabric (15) during the pushing of the fabric (15) with the rotation of the drum (101) and the pulling of the fabric (15) from the housing (14) by the outlet pipe (17). The pipes (102) are fixed with the drum shaft (103), the rear mirror (105) and the front mirror (104).
Pipes (102) can be formed by teflon-coated or water-resistant plastic coating.
On the surface of the front mirror (104), the cages (106) are positioned as shown in Figures 12 and 13.
The cages (106) are located at equal distance to the center of the front mirror (104) and to each other. At least 3 units are positioned. They are at equal distances to the center of the front mirror (4) and to each other when they are placed as triple or quadruplet. The cages (106) allow the magnets to be fixed.
The magnets are positioned within the cages (106). The cages (106) are formed on the surface of the drive mirror (111) in the same manner with respect to the position and the numbers of the cages (106).
In particular, the magnets positioned on the front mirror (104) of the drums (101) are covered for the purpose of water resistance. The waterproofing device is also housed in such a way that the conductor feature is not disturbed.
The magnets are fixed in the cages (106) formed on the surface of the drive mirror (111). With the same principle, the drive mirror (111) is disposed at the center and at equal distances.
For example, if the drive mirror (111) includes 4 cages (106) as seen in Figure 9, 4 cages (106) are formed on the front mirror (104) of the drum (101), as shown in Figure 12. The magnets are positioned within each formed cage (106).
With respect to the direction and position of the magnets, the ones in the drive mirror (111) have pole orientation such that they are applied to the magnets in the position of the front mirror (104) cage (106).
Magnets positioned in the drive mirror (111) are positioned in the direction of forming a drafting zone.
In this way, the possibility of creating different direction is eliminated. Magnets positioned in the drum front mirror (104) are pulled by the magnets positioned in the drive mirror (111). According to this rule, the magnets are disposed corresponding to each other on the front mirror (104) and on to the cages (106) located on the drive mirror (111).
In order to ensure rotation with the same frequency, the magnets placed in the cages (106) located on the surface of the drive mirror (111) are positioned in a pole orientation that ensures the pull of the magnets located in the cages on the front mirror surface, preventing the deterioration of this balance and providing the continuation of the same operation.
The cages (106) stabilize the balance and position of the magnets, preventing the deterioration of the magnets by impacts.
Originally, the operation of the system is provided by positioning the cages (106) in the correct positions and evenly on the front mirror (104) and the drive mirror (111).
The sealing flange (112) formed between the front mirror (104) and the drive mirror (111) is positioned so as not to come into contact with the cages (106) formed on both.
The body housing (21.1) formed on the tower body (21) is fixed to the body by welding or similar methods. Connection can also be made with screw systems. In order to provide full insulation, especially welded in the whole form.
It is also made of material that does not isolate the magnetic attraction effect. The tower body (21) is located in the body slot (21.1) so as to prevent fluid and pressure losses.
With the detail view in Figures 6 and 7, the drum (101) is positioned as the cages (106) positioned on the front mirror (104) and the drive mirror (111) the cages (106) are matched.
In its most basic case, the drive unit (107) is formed by the motor (108), the drive shaft (110), the drive mirror (111), the sealing flange (112), the mounting flange (113) and the extension flange (114).
The motor (108) is connected to the drive mirror (111) via the drive shaft (110). The rotation movement formed in the motor (108) is transferred to the drive mirror (111) via the drive shaft (110).
The mounting flange (113) provides the connection of the motor (108), drive mirror (111) and the extension flange (114). It also ensures that the drive unit (107) is fixed to the tower body (21).
The drive unit (107) is positioned as a whole in the body slot (21.1) formed on the tower body (21) by means of the mounting flange (113).
The movement transmission is provided by magnets positioned in the cages (106) arranged on a drive mirror (111) and on the front mirror (104).
The rotational movement of the motor (108) is transmitted via the drive shaft (110) to the drive mirror (111) and it is rotated in its own axis. The rotation of the drive mirror (111) provides the rotation of the magnets located in the cages (106) by the rotation of the shaft.
With this rotation, it is shown that the sealing flange (112) is rotated by driving at the same frequency by applying attraction to the magnets on the front mirror (104) at the other side. It is provided that the front mirror (104) is rotated in a non-contact manner using the magnet push and pull effect. The rotation of the front mirror (104) in its axis enables the rotation of the rear mirror (105) connected by the drum shaft (110) and the pipes (102) positioned between the two mirrors. This allows the drum (101) to rotate in its axis.
The mounting bushing (115) is formed on the surface of the sealing flange (112) between the front mirror (104) and the drive mirror (111), which allows the drum shaft (103) to be held and rotated in the desired plane on the surface facing the interior of the tower.
Since the sealing flange (112) completely cuts the connection between the tower (20) and the external environment, the internal fluid and pressure balance is easily achieved. The tower (20) is completely closed. The drive unit (107) is outside the tower (20) and the magnets positioned in the cages (106) on the drive mirror (111) and on the front mirror (104) are rotated at the same frequency to each other, enabling the power transmittance to the drum (101) without contact.
The extension flange (114) formed in the drive unit (107) allows the distance between the motor (108) and the tower body (21) to be adjusted. At the same time, the distance between the sealing flange (112) of the drive mirror (111) can be adjusted.
The drive shaft (110) extends over the motor (108) to the center of the drive mirror (111) and is fixed.
The mounting flange (113) enables the motor (108) and the extension flange (114) to be joined together. It has a housing in which the drive shaft (110) can be passed through and which will not interfere with the rotation of the drive shaft (110).
In other words, there is a mounting flange (113) located behind the drive mirror (111), which enables the elements of the drive unit (107) to be joined together, and which also connects to the tower body (21).
