Description

Technical Field

[0001] The present invention relates to the technical field of cloth dyeing devices, and in particular to a continuous printing and dyeing device for industrial fabrics. Background Art

[0002] Printing and dyeing (dyeing and finishing) is a process for processing industrial fabrics, covering multiple steps such as pretreatment, dyeing, printing, and post-finishing. In the existing process, dyeing and printing usually require different devices: a dyeing machine for uniformly coloring the fabric and a printing device for printing on the fabric; workers continuously transport the dyed fabric to the printing equipment through a transmission device to complete the entire printing and dyeing process.

[0003] An air-flow dyeing machine is one of the commonly used dyeing machines. The air-flow dyeing machine passes the stacked fabric into the dyeing device, and then uses high-pressure air flow to atomize and spray the dye liquor onto the stacked fabric, so that the dye liquor uniformly penetrates the fabric under the action of high-pressure gas, thereby enabling the air-flow dyeing machine to achieve the purpose of uniform coloring and saving dyes. When the fabric enters the air-flow dyeing machine, there will be a situation where the number of stacked layers of the fabric is too many and too thick in some parts during the transportation process, which will cause the dye liquor to be difficult to fully penetrate to the center part of the fabric stack under the action of high-pressure gas, thus affecting the uniformity of fabric dyeing. This problem of uneven fabric dyeing will not only reduce the quality of the fabric finished product, but also affect the subsequent printing effect of the fabric. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A continuous dyeing and printing device for industrial fabrics, reference Figures 1-7 , including: a shell 1, the shell 1 is provided with a liquid supply module and at least one printing and dyeing chamber, the printing and dyeing chamber of the shell 1 is rotatably connected with a cloth lifting roller 2, the printing and dyeing chamber of the shell 1 is fixed with at least two scattering shells 3 and a printing and dyeing part 4, and the printing and dyeing part 4 and the adjacent scattering shells 3 and the two scattering shells 3 are connected through fixed pipes, the scattering shell 3 is provided with a detection component and a uniformly distributed first sliding frame 301, the first sliding frame 301 is slidably connected with a sliding plate 5, the sliding plate 5 is provided with a smoothing component, the smoothing component is used to drive the cloth to move by friction, and smooth the position where the cloth is accumulated, and the detection component is used to detect the accumulation degree of the cloth at different positions.

[0022] Preferably, reference Figures 5-8 The smoothing component includes two rollers 6, which are rotatably connected to the sliding plate 5. A conveyor belt 7 is commonly provided on the two rollers 6 on the same sliding plate 5. The conveyor belt 7 is installed with a mounting block 8. The mounting block 8 is fixed with evenly distributed toggle plates 9. The toggle plates 9 are provided with horizontal grooves. A trigger assembly is provided between two adjacent sliding plates 5 on the same spreading shell 3. The trigger assembly is used to push the adjacent sliding plates 5 to move so that the toggle plates 9 are in contact with the cloth. A transmission assembly is provided in the spreading shell 3. The transmission assembly is used to drive the toggle plates 9 in contact with the cloth to rotate.

[0023] Preferably, reference Figure 8 The length of the toggle plate 9 on the spreading shell 3 close to the cloth lifting roller 2 is greater than the length of the toggle plate 9 on the spreading shell 3 away from the cloth lifting roller 2.

[0024] In the above scheme, a plurality of printing and dyeing chambers can be arranged in the housing 1 (i.e., printing and dyeing multiple pieces of cloth at the same time), wherein one of the printing and dyeing chambers contains at least two spreading shells 3, one printing and dyeing part 4 and a cloth lifting roller 2. This scheme is described only with respect to one of the printing and dyeing chambers and the components thereon. The liquid supply module includes an air supply device 101, a liquid supply device 102, and a liquid supply pipeline 103. The housing 1 is provided with a feed inlet 104, a feed outlet 105 and a control terminal. The printing and dyeing part 4 contains uniformly distributed dyeing nozzles 401, which are connected to the air supply device 101 and the liquid supply pipeline 103 (not shown in the figure). The air supply device 101 is used to supply liquid to the dyeing nozzles 401. High-pressure gas is supplied inside, and the liquid supply device 102 is used to heat the dye liquid and supply the dye liquid to the dyeing nozzle 401 through the liquid supply pipe 103, so that the high-pressure gas sprays the dye liquid onto the cloth. The feed port 104 is located between the discharge port 105 and the cloth lifting roller 2; a plurality of auxiliary nozzles 27 are arranged in the spreading shell 3, and the auxiliary nozzles 27 are located on the side of the spreading shell 3 close to the printing and dyeing part 4. The air supply device 101 is connected with the auxiliary nozzles 27 (not shown in the figure), and the auxiliary nozzles 27 are used to push the cloth in the spreading shell 3 through airflow, so that the cloth passes through the printing and dyeing part 4. The cloth lifting roller 2, the air supply device 101 and the liquid supply device 102 are all electrically connected to the control terminal.

[0025] The toggle plate 9 is made of a flexible friction material (such as rubber material) to reduce the rigid squeezing of the toggle plate 9 on the fabric and prevent the fabric from folding due to excessive squeezing force. The spacing between two adjacent toggle plates 9 in the left-right direction is greater than the thickness of one toggle plate 9, so that the toggle plate 9 can be bent and deformed in the left-right direction. The toggle plate 9 mainly drives the fabric to move in its own moving direction through the friction between itself and the fabric (therefore, during the bending and deformation of the toggle plate 9, the larger the contact area between the toggle plate 9 and the fabric, the greater the friction between the two); Figure 7 As shown, the toggle plate 9 is rectangular, so that the toggle plate 9 can be deformed in the left and right direction but not in the front and back direction; the two spreading shells 3 adjust the cloth stacking position in turn, and the height of the toggle plate 9 in the front spreading shell 3 is smaller than the height of the toggle plate 9 in the front spreading shell 3. Therefore, the contact area between the rear toggle plate 9 and the cloth is smaller than the contact area between the front toggle plate 9 and the cloth. The friction force of the toggle plate 9 in the rear spreading shell 3 on the cloth is small, and it is mainly used to fine-tune the position of the cloth.

[0026] The working process is as follows: When the staff is preparing to dye the fabric, they first perform pre-treatment on the fabric. Subsequently, the cloth lifting roller 2, the air supply device 101, and the liquid supply device 102 are started through the control terminal. The staff passes one end of the fabric through the feeding port 104, so that the fabric bypasses the upper side of the cloth lifting roller 2 and enters the front side distribution shell 3. The cloth lifting roller 2 continuously drags the fabric into the housing 1. Subsequently, the fabric passes through the detection component in the front side distribution shell 3 and moves backward under the drive of the auxiliary air jet head 27 (in the initial state, the toggle plate 9 is located inside the inner wall of the adjacent distribution shell 3, and the fabric does not contact the toggle plate 9). After passing through the front side distribution shell 3, the fabric sequentially passes through the fixed pipe between the two distribution shells 3, the rear side distribution shell 3, the fixed pipe between the dyeing part 4 and the rear side distribution shell 3, and into the dyeing part 4. The liquid supply device 102 supplies the dye solution to the dyeing nozzle 401 through the liquid supply pipe 103, and the air supply device 101 supplies high-pressure gas into the dyeing nozzle 401 to spray the dye solution into the dyeing part 4. The dye solution uniformly penetrates and adheres to the fabric. After passing through the dyeing part 4, the fabric is discharged downward from the rear side of the dyeing part 4. After the end of the fabric is cooled, the staff first drags the end of the fabric at the bottom of the housing 1 to the discharge port 105, and the other fabrics are sequentially stacked at the bottom of the housing 1 for cooling. The staff pulls out the end of the fabric through the discharge port 105 and drags the end of the fabric to the next process.

[0027] When serious stacking of fabrics occurs after entering the outer shell 1, the stacked fabrics first trigger the detection component in the front scattering shell 3 after entering the front scattering shell 3. The detection component detects the specific position where serious stacking of fabrics occurs, and transmits the signal to the control terminal. The control terminal controls the trigger component and the transmission component to drive the sliding plate 5, the roller 6, the conveyor belt 7, the mounting block 8 and the toggle plate 9 at the corresponding position to work. Take the two groups of sliding plates 5 on the left and right sides of the position where serious stacking of fabrics occurs as an example: the control terminal first controls the left and right groups of sliding plates 5, the roller 6, the conveyor belt 7, the mounting block 8 and the toggle plate 9 to move downward along the first sliding frame 301 through the trigger component, so that the toggle plate 9 extends out of the inner wall of the scattering shell 3 and contacts the fabric. Then the control terminal activates the transmission component, and the transmission component drives the roller 6 on the left side of the fabric stacking position. The conveyor belt 7 rotates clockwise (from the front to the back), and the roller 6 and the conveyor belt 7 on the right side of the cloth stacking position rotate counterclockwise (from the front to the back). When the two conveyor belts 7 rotate, they respectively drive the mounting blocks 8 and the toggle plates 9 thereon to rotate together. The two sets of toggle plates 9 respectively toggle the cloth in the direction of rotation by friction, so that the stacked cloth is spread out to the left and right. When the spread cloth passes through the rear spreading shell 3, the detection component in the rear spreading shell 3 detects the cloth again according to the same principle, and controls the trigger component and the transmission component in the rear spreading shell 3 to spread the cloth again, thereby reducing the probability that the cloth is still in a serious stacking state when entering the printing and dyeing part 4, thereby improving the uniformity of the printing and dyeing part 4 when dyeing the cloth. When the cloth is no longer stacked, the control terminal controls the trigger component to drive the two sets of sliding plates 5 to move upward and reset.

[0028] Preferably, reference Figure 5 , Figure 9 and Figure 10 The detection component includes: a second sliding frame 10, having a plurality of members, all of which are slidably connected to adjacent scattering shells 3, the second sliding frame 10 is rotatably connected to an extrusion roller 11, an elastic force detector 12 is fixedly connected to the second sliding frame 10, and a first elastic member 13 is installed between the elastic force detector 12 and the adjacent scattering shell 3.

[0029] Preferably, reference Figure 9 All the second sliding frames 10 on the same spreading shell 3 are staggered and arranged to reduce the gap between two adjacent squeezing rollers 11. The projections of all the squeezing rollers 11 on the same spreading shell 3 on the adjacent spreading shells 3 in the vertical direction are complete rectangles.

[0030] In the above solution, the elastic force detector 12 is electrically connected to the control terminal; the number of the second sliding frames 10 on the same spreading shell 3 is one less than the number of the sliding plates 5, and each second sliding frame 10 is located on the symmetry plane of two adjacent sliding plates 5. The second sliding frame 10 contacts the fabric through the pressing roller 11 to reduce the frictional force on the fabric. When the fabric is not severely stacked, the density at the cross-section of the fabric is small and the overall thickness of the fabric is small. Therefore, the fabric will not push the pressing roller 11 upward. When part of the fabric is in a severely stacked state, the density of the fabric at the cross-section of this part of the fabric increases, resulting in a larger thickness of the fabric at the severely stacked part. At this time, when the fabric passes through the pressing roller 11, it presses the pressing roller 11 and the second sliding frame 10 to move upward; the distribution state of all the pressing rollers 11 on the same spreading shell 3 is as Figure 9 shown. All the pressing rollers 11 are staggered and in a connected state to reduce the gap between two adjacent pressing rollers 11, thereby increasing the detection accuracy; the first elastic member 13 is a spring, and the height of the pressing roller 11 and the first elastic member 13 can be changed and replaced according to the specific production situation.

[0031] Working process: When the severely stacked fabric passes under the second sliding frame 10, taking one of the second sliding frames 10 as an example: the severely stacked fabric presses the pressing roller 11 upward, and the pressing roller 11 drives the adjacent second sliding frame 10 to move upward quickly. The second sliding frame 10 drives the elastic force detector 12 to press the first elastic member 13 upward. The elastic force detector 12 detects the change in the elastic force of the first elastic member 13 and transmits the signal to the control terminal. The control terminal starts to spread out the stacked fabric. As the pressing roller 11 moves upward, the pressing force of the fabric on the pressing roller 11 gradually decreases. When the pressing force is equal to the elastic force of the first elastic member 13, the second sliding frame 10 and the pressing roller 11 stop moving upward. When the severely stacked fabric passes through the pressing roller 11, the pressing roller 11 is no longer subjected to the pressing force of the severely stacked fabric. The pressing roller 11 and the second sliding frame 10 move downward and reset under the elastic force of the adjacent first elastic member 13. When the elastic force of the first elastic member 13 is completely released, the elastic force detector 12 transmits the signal to the control terminal again, and the control terminal stops the action of spreading out the fabric.

[0032] Preferably, referring to Figures 7-9 and Figure 11 , the triggering assembly includes: an electric push rod 14 fixed inside the adjacent spreading shell 3. The telescopic end of the electric push rod 14 is fixed with a pressing plate 15. The pressing plate 15 is slidably connected with spaced connecting blocks 16, and a second elastic member 17 is installed between the pressing plate 15 and the connecting blocks 16. The connecting blocks 16 are fixed to the adjacent sliding plates 5.

[0033] Preferably, referring to Figure 8 , Figure 9 and Figure 11, the transmission assembly includes a number of second transmission wheels 19, and a number of second transmission wheels 19 are all rotatably connected within the spreading shell 3; except for the outermost roller 6, other rollers 6 are all rotatably connected with second friction wheels 21; the spreading shell 3 is rotatably connected with a number of first transmission wheels 18, and the number of first transmission wheels 18 is the same as the number of second friction wheels 21 within the adjacent spreading shell 3. The first transmission wheels 18 are fixedly connected with first friction wheels 20. All the second transmission wheels 19 and all the first transmission wheels 18 on the same spreading shell 3 are jointly wound with a belt. One of the second transmission wheels 19 is a driving wheel, and the second friction wheel 21 and the adjacent first friction wheel 20 transmit power through friction. The roller 6 close to the second friction wheel 21 is provided with a connection assembly, and the connection assembly is used to control the connection or disconnection between the adjacent second friction wheel 21 and the adjacent roller 6.

[0034] Preferably, referring to Figures 11-13 , the connection assembly includes: a connecting member 22, splined to the adjacent roller 6, and a third elastic member 23 is installed between the two. The connecting member 22 is used to limit the second friction wheel 21; a first magnet 24, slidably connected to the adjacent sliding plate 5. The first magnet 24 and the adjacent connecting member 22 are coaxial. The connecting member 22 has a magnetic force near the adjacent first magnet 24, and the magnetic forces of the two repel each other; a driving assembly, arranged on the adjacent pressing plate 15, and used to push the adjacent first magnet 24 to move.

[0035] Preferably, referring to Figures 13-15 , the driving assembly includes: an elastic telescopic rod 25, fixedly connected to the adjacent pressing plate 15; a second magnet 26, fixedly connected to the telescopic end of the elastic telescopic rod 25. The upper side of the second magnet 26 repels the adjacent first magnet 24, and the lower side of the second magnet 26 magnetically attracts the adjacent first magnet 24.

[0036] In the above solution, the second transmission wheel 19 (driving wheel) responsible for driving and the electric push rod 14 are both electrically connected to the control terminal. On the same spreading shell 3, except for the outermost roller 6, the first transmission wheels 18 and the rollers 6 are in one-to-one correspondence. The winding method of the belt in the second transmission wheels 19 and the first transmission wheels 18 is as Figure 9As shown, the rotation directions of the two adjacent first transmission wheels 18 are opposite; the connecting member 22 is provided with a keyway, and the second friction wheel 21 drives the connecting member 22 to rotate together by being inserted into the keyway of the adjacent connecting member 22; the first magnet 24 does not contact the adjacent roller 6, and the magnetic force of the first magnet 24 repels the magnetic force of the connecting member 22, so when the roller 6 and the connecting member 22 rotate, there is no friction between the two and the first magnet 24, thereby extending the service life of the first magnet 24 and improving the sensitivity of the first magnet 24 (that is, the friction resistance during movement is small); the connecting member 22 is provided with an inclined surface on one side close to the adjacent second friction wheel 21, which is used to increase the smoothness when the two are connected; the second elastic member 17 and the third elastic member 23 are both springs, and the lower side of the second magnet 26 is aligned with the adjacent first magnet 24 in the initial state.

[0037] Workflow: When the second sliding frame 10 is squeezed by the seriously stacked cloth, the control terminal starts the trigger component, and the control terminal directly starts the second transmission wheel 19 responsible for driving. All the second transmission wheels 19 and all the first transmission wheels 18 rotate clockwise under the drive of the second transmission wheel 19. At this time, assuming Figure 11 Taking the electric push rod 14 and the second sliding frame 10 as an example (that is, the control terminal needs to drive the two sets of sliding plates 5, rollers 6, conveyor belts 7, mounting blocks 8 and toggle plates 9 there to work), the control terminal controls the telescopic end of the electric push rod 14 to extend downward, and the telescopic end of the electric push rod 14 drives the extrusion plate 15 to move downward. The extrusion plate 15 squeezes the two lower connecting blocks 16 through the second elastic member 17 and moves downward together. The connecting block 16 drives the adjacent sliding plates 5 and the parts thereon to move downward together until the sliding plates 5 move to the lowest end of the stroke, and the sliding plates 5 stop moving. At this time, the toggle plate 9 protrudes out of the inner wall of the spreading shell 3, and all the second friction wheels 21 on the two sliding plates 5 are respectively in contact with the adjacent first friction wheels 20, and the first friction wheels 20 drive the adjacent second friction wheels 21 to rotate. At this time Figure 11 The second friction wheel 21 on the left side rotates clockwise ( Figure 11 From the front to the rear), the second friction wheel 21 on the right side rotates counterclockwise, and at this time all the connecting members 22 are not in contact with the adjacent second friction wheel 21.

[0038] When the sliding plate 5 stops moving downward, the connecting block 16 thereon also stops moving downward at the same time. The telescopic end of the electric push rod 14 continues to move downward by a certain distance, compressing and storing energy in the adjacent second elastic member 17. The extrusion plate 15 drives the second magnet 26 to continue moving downward by a certain distance through the elastic telescopic rod 25. The second magnet 26 makes a relative movement with the first magnet 24, and the upper side of the second magnet 26 gradually aligns with the first magnet 24. Under the repulsive magnetic force of the second magnet 26, the first magnet 24 moves forward. During the movement of the first magnet 24, it pushes the connecting member 22 forward, causing the keyway of the connecting member 22 to gradually move to the position where it contacts the second friction wheel 21 and gradually sleeve on the outside of the second friction wheel 21, that is, the second friction wheel 21 is inserted into the keyway of the connecting member 22. At this time, the second friction wheel 21 drives the connecting member 22 and the adjacent roller 6 to rotate together. The roller 6 on the left side and the conveyor belt 7 rotate clockwise, and the roller 6 on the right side and the conveyor belt 7 rotate counterclockwise, so that the dialing plates 9 on the front and back sides spread out the severely stacked fabric along different paths, facilitating the dyeing of the fabric by the dyeing piece 4.

[0039] After the severely stacked fabric passes through, the second sliding frame 10 moves downward to reset under the elastic force of the first elastic member 13 thereon. The control terminal synchronously controls the telescopic end of the electric push rod 14 to drive the adjacent components to move and reset. The components on the telescopic end of the electric push rod 14 move and reset according to the above opposite steps under the action of the second elastic member 17 and the third elastic member 23.

[0040] Preferably, referring to Figures 13-15 , it further includes: adjusting components, which are provided on all the sliding plates 5 except the outermost sliding plate 5, and are used to prevent the two connecting members 22 on the same sliding plate 5 from being connected to the adjacent second friction wheels 21 at the same time. The adjusting components include: a liquid storage tank 28, which is fixedly connected to the adjacent sliding plate 5. A liquid pushing plate 281 is slidably connected in the liquid storage tank 28, and a tension spring is fixedly connected between the two. There are two hydraulic telescopic rods 29, which are respectively fixedly connected to the adjacent connecting blocks 16 on the same sliding plate 5. The telescopic ends of the hydraulic telescopic rods 29 are fixedly connected to the adjacent second magnets 26. The hydraulic telescopic rods 29 are communicated with the adjacent liquid storage tank 28 through hoses.

[0041] In the above solution, it is aimed to prevent the severely stacked fabric from being simultaneously located under the two squeezing rollers 11, resulting in the simultaneous operation of the electric push rods 14 on both sides of the same sliding plate 5, so that when the two second friction wheels 21 on the sliding plate 5 are simultaneously connected to the adjacent rollers 6, the two second friction wheels 21 drive the adjacent rollers 6 to rotate in opposite directions at the same time, causing frictional wear between the two rollers 6 on the sliding plate 5 and the adjacent conveyor belt 7. The volume of the liquid storage tank 28 is equal to the volume of the hydraulic telescopic rod 29. In the initial state, the liquid storage tank 28 is filled with hydraulic oil, and no hydraulic oil is stored in the two hydraulic telescopic rods 29.

[0042] Workflow: When only one electric push rod 14 is activated by the control terminal, after the telescopic end of the electric push rod 14 stops sliding on the sliding plate 5, the adjacent connecting block 16 stops moving downward. When the telescopic end of the electric push rod 14 drives the pressing plate 15, the elastic telescopic rod 25, and the second magnet 26 to continue moving downward, the second magnet 26 continues to move downward relative to the connecting block 16, and the telescopic ends of the adjacent hydraulic telescopic rods 29 extend downward. The hydraulic telescopic rods 29 extract the hydraulic oil in the liquid storage tank 28, and the liquid pushing plate 281 moves backward. The tension spring on the liquid pushing plate 281 stretches and stores energy. When the second magnet 26 stops moving, the hydraulic oil in the liquid storage tank 28 is just completely extracted, and at this time, the device operates normally.

[0043] When the electric push rods 14 on both sides of the same sliding plate 5 are activated by the control terminal, taking the components on this sliding plate 5 as an example: When the sliding plate 5 moves to the lowest side of its stroke and stops moving downward, the two electric push rods 14 still need to move downward a certain distance. At this time, the two second magnets 26 move downward respectively driven by the adjacent elastic telescopic rods 25 and the adjacent electric push rods 14. The two hydraulic telescopic rods 29 extract the hydraulic oil in the liquid storage tank 28 at the same time. When the hydraulic oil in the liquid storage tank 28 is exhausted, the two hydraulic telescopic rods 29 only move downward by half of their stroke. The telescopic ends of the two hydraulic telescopic rods 29 are both subjected to the downward forces transmitted by the adjacent elastic telescopic rods 25 and the adjacent second magnets 26, and the magnitudes of the two forces are equal. Therefore, the telescopic ends of the two hydraulic telescopic rods 29 and the two second magnets 26 all stop moving downward, and the two elastic telescopic rods 25 are compressed to store energy. Because the upper side of the second magnet 26 is not aligned with the first magnet 24, the first magnet 24 is still subjected to the magnetic attraction force on the lower side of the second magnet 26. At this time, the forces exerted on the first magnet 24 by the upper side and the lower side of the second magnet 26 cancel each other out, and the first magnet 24 remains in place and does not move. Therefore, the two second friction wheels 21 on this sliding plate 5 are not connected to the roller 6, avoiding the situation where the two second friction wheels 21 drive the adjacent roller 6 to rotate in opposite directions at the same time. And at this time, the sliding plates 5 on the left and right sides of this sliding plate 5 work together to spread out the fabric. When the control terminal controls the telescopic ends of the two electric push rods 14 to move back to their original positions, the telescopic ends of the two electric push rods 14 drive the adjacent components to reset according to the above opposite process.

Therefore, the detailed description of the embodiments of this disclosure is only for explanation and should not be regarded as a limitation of the present invention.
