Description

Technical Field

[0001] The present application relates to the technical field of dyeing, and in particular to a fiber processing and dyeing device and a dyeing method thereof. Background Art

[0002] Overflow dyeing machine can be used for dyeing a variety of fiber fabrics, including cotton, linen, silk, wool, viscose fiber, acrylic fiber, chemical fiber and their blended knitted fabrics, woven fabrics, etc., which can meet the dyeing needs of different fiber materials.

[0003] After long-term production practice, the overflow dyeing machine has optimized the fabric storage tank structure into three types: compact O-type or U-type, tubular L-type and J-type. Among them, the most significant advantage of the U-type or O-type fabric storage tank is that the grey cloth or fabric is compactly stacked in the fabric storage tank, making the overflow dyeing machine bath ratio low. Its disadvantage is that the grey cloth or fabric is stacked up and down in the U-type or O-type fabric storage tank, which is easy to wrinkle. The L-type structure fabric storage tank is a long horizontal type, which causes the overflow dyeing machine bath ratio to be greater than the U-type or O-type structure fabric storage tank. The fabric or grey cloth is stacked loosely in the L-type fabric storage tank in a wavy shape. Its advantage is that it can prevent permanent wrinkles caused by the stacking of fabrics up and down. However, if the bath ratio is not appropriate and the dye flow rate is too fast, it will hinder the wavy distribution of the dyed cloth, and it is difficult to adjust the process parameters. The J-type structure combines the advantages of O-type, U-type and L-type, but it also has the disadvantage of limited applicability to fabrics. Summary of the invention

[0004] The present application proposes a fiber processing and dyeing device and a dyeing method thereof, which divides the stacked dyed cloth by a dividing rod that moves synchronously with the dyed cloth, thereby separating the weight of the stacked cloth, and the cloth stacked between the two dividing rods is always kept appropriate to avoid creases. Secondly, the dyed cloth is mainly moved in the cloth storage tank by the dividing rod and the traction rope. At the same time, the dyed cloth is relatively loose and fully interacts with the dye solution to reduce the tension of the dyed cloth. At the same time, the angle at which the dyed cloth goes out of the cloth storage tank is relatively fixed, thereby reducing the friction between the dyed cloth and the outlet of the cloth storage tank.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a fiber processing and dyeing device, comprising a cloth storage trough and a cloth guide trough, the cloth storage trough is composed of a horizontal section and a vertical section, the horizontal section and the vertical section are smoothly transitioned by an arc, a nozzle and a cloth guide roller are provided on the top of the vertical section, the cloth guide trough is arranged between the horizontal section and the vertical section, an inlet and outlet are provided on one side of the vertical section, a plurality of dividing rods are provided in the cloth storage trough, the dividing rods are connected with a traction rope, the traction rope drives the dividing rods to move in a cycle, the density of the dividing rods is less than the density of the dye solution, and the dividing rods can float on the upper part, the inner wall of the cloth storage trough is provided with a driving wheel and a guide wheel, the traction rope moves in a cycle around the guide wheel and the driving wheel, the rotation of the driving wheel drives the traction rope to move, one end of the traction rope is located in the vertical section, and the other end of the traction rope passes over the connection between the cloth guide trough and the horizontal section, the dividing rod can move to the innermost side of the bend of the dyed cloth at the position of the traction rope to divide the dyed cloth into multiple relatively independent parts.

[0006] Furthermore, the end of the traction rope in the vertical section is the front end, which is inclined upward. The position where the dyed cloth falls is located in the middle of the inclined section. The front end is higher than the liquid surface. The dyed cloth here has a smaller bending, and the lateral movement of the dividing rod will not disrupt the stacked dyed cloth.

[0007] Furthermore, the driving wheel is located at the end point of the front end near one side of the lying section, and the end point on the other side is provided with an obstruction block corresponding to the guide wheel. The obstruction block is elastic and can hinder the movement of the dividing rod. The traction rope is connected to the dividing rod through a connecting rope. The connecting rope is elastic. When the dividing rod moves to the end point of the front end, it is blocked by the obstruction block, and the traction rope continues to move. When the end point of the connecting rope is close to the driving wheel, the elastic force can overcome the obstruction block, so that the dividing rod passes through the obstruction block. In this way, the upper end of the traction rope is relatively loose, and the dividing rod that divides and constrains the dyed cloth has a larger degree of freedom, which is convenient for the dyed cloth to interact with the dye.

[0008] Furthermore, the driving wheel includes a rotating wheel, a driving groove is provided on the outer side of the rotating wheel, and a suction block corresponding to the driving groove is provided on the traction rope. The suction block can be inserted into the driving groove to increase the force between the driving wheel and the traction rope, ensuring that the traction rope will not slip.

[0009] Furthermore, a magnet is provided in the rotating wheel, a wedge is filled in the suction block, the suction block can be sucked into the driving groove, the driving wheel is located at the highest point of the traction rope, and baffles are provided on both sides of the rotating wheel.

[0010] Furthermore, monitoring components are provided on both the front and rear sides of the connection between the horizontal section and the cloth guide groove. The monitoring components can sense contact with the dyed cloth. The contact position between the monitoring component and the dyed cloth is located within the projection of the connection between the cloth guide groove and the vertical section. When the dyed cloth contacts the monitoring component on the front side, the speed of the traction rope increases by one level. If it contacts the monitoring component on the rear side, the speed of the traction rope decreases by one level, so as to ensure that both the front and rear monitoring components are not in contact with the dyed cloth.

[0011] Furthermore, the monitoring component includes a rotating rod, which passes through the side wall of the horizontal section. The rotating rod is fixedly connected to a rotating frame, on which is a sensing rope. One end of the sensing rope is connected to a pressure sensor. When the sensor connected to the sensing rope senses that the high pressure is greater than the threshold and the duration exceeds the set time, it is determined that the dyed cloth is in contact with the monitoring component.

[0012] The beneficial effects of the present invention are as follows:

[0013] The present application provides a fiber processing and dyeing device and a dyeing method thereof, which divide the stacked dyed cloth by a dividing rod that moves synchronously with the dyed cloth, thereby separating the weight of the stacked cloth. The cloth stacked between the two dividing rods is always kept appropriate to avoid creases, and when the dyed cloth enters the vertical section, the stacked cloth is properly loosened to further reduce the probability of creases on the cloth. In addition, since the folding of the dyed cloth is kept appropriate and relatively high, the dye bath ratio is low, thereby reducing the amount of dye used.

[0014] The dyed cloth is mainly moved in the cloth storage trough by the dividing rods and the traction ropes. At the same time, the dyed cloth is relatively loose and fully reacts with the dye solution. On the one hand, the tension of the dyed cloth is small when the nozzle and the guide roller pull the dyed cloth, which ensures the quality of the dyed cloth. On the other hand, the angle of the dyed cloth leaving the cloth storage trough is relatively fixed, which reduces the friction between the dyed cloth and the outlet of the cloth storage trough.

DETAILED DESCRIPTION

[0023] 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.

[0024] For example, see Figure 1-Figure 3 A fiber processing and dyeing device comprises a cloth storage tank and a cloth guide tank 4. The cloth storage tank is composed of a horizontal section 1 and a vertical section 2. The height of the vertical section 2 is between that of the U-shaped cloth storage tank and the L-shaped cloth storage tank, and can accommodate a proper amount of dyed cloth stacked up and down. The horizontal section 1 and the vertical section 2 are smoothly transitioned by an arc. A nozzle 5 and a cloth guide roller 6 are arranged on the top of the vertical section 2. The cloth guide tank 4 is arranged between the horizontal section 1 and the vertical section 2. An inlet and outlet 3 is arranged on one side of the vertical section 2. The dyed cloth enters the cloth storage tank from the inlet and outlet 3. The dyed cloth moves along the horizontal section 1, the vertical section 2 and the cloth guide tank 4. After passing through the cloth guide tank 4, the dyed cloth passes through the nozzle 5 and goes around the cloth guide roller 6 to return to the horizontal section 1.

[0025] A plurality of dividing rods 7 are provided in the cloth storage trough, and the dividing rods 7 are connected with traction ropes 8, which drive the dividing rods 7 to move in a circular motion. The density of the dividing rods 7 is less than the density of the dye solution, and the dividing rods 7 can float on the upper part. In order not to interfere with the movement of the dyed cloth, two groups of traction ropes 8 are provided, and the two groups of traction ropes 8 are respectively arranged on both sides of the cloth storage trough. The two ends of the dividing rods 7 are respectively connected to the two groups of traction ropes 8. The inner wall of the cloth storage trough is provided with a driving wheel 10 and a guide wheel 9. The traction rope 8 moves in a circular motion around the guide wheel 9 and the driving wheel 10. The driving wheel 10 is transmission-connected to a motor, and the rotation of the driving wheel 10 drives the traction rope 8 to move. The part of the traction rope 8 located in the vertical section 2 is located at the height of the vertical section 2, close to the highest point of the dyed cloth folding, and the part of the traction rope 8 located in the horizontal section 1 passes over the connection between the cloth guide groove 4 and the horizontal section 1.

[0026] When the dyed cloth falls into the vertical section 2, a part of it will be stopped by the dividing rod 7, and the dyed cloth begins to stack with the dividing rod 7 as the starting point. The weight of the stacked dyed cloth mainly acts on the dividing rod 7, and will not continue to apply downward pressure. The dividing rod 7 is soft and has a smooth surface, that is, the stacked dyed cloth is divided into multiple parts by the dividing rod 7, and the gravity at the lowest point of the stacked cloth will not be too large, and no creases will be generated. When the dyed cloth enters the horizontal section 1 along with the dividing rod 7, it will become loose again, and because the two ends are constrained by the dividing rod 7, it will not become excessively loose. While the bath ratio is low, the requirements for process parameters are relatively low.

[0027] The end of the traction rope 8 located in the middle of the vertical section 2 is the front end, and the front end is inclined upward, that is, the part close to the inlet and outlet 3 is shorter, and the part close to the horizontal section 1 is higher. The position where the dyed cloth falls is located in the middle of the inclined section, and the front end is higher than the liquid surface. The dyed cloth here is less bent, and the lateral movement of the dividing rod 7 will not disrupt the stacked dyed cloth. The driving wheel 10 is located at the end point on the side of the horizontal section 1 at the front end, so that the upper end of the traction rope 8 is relatively loose, and the dividing rod 7 for dividing and restraining the dyed cloth has a larger degree of freedom, which is convenient for the dyed cloth to interact with the dye. The end point on the other side is provided with an obstruction block 12 corresponding to the guide wheel 9. The distance between the obstruction block 12 and the guide wheel 9 is smaller than the diameter of the dividing rod 7. The obstruction block 12 is elastic and can temporarily obstruct the movement of the dividing rod 7. The traction rope 8 is connected to the dividing rod 7 by a connecting rope 11. The connecting rope 11 is elastic. When the dividing rod 7 is divided, the connecting rope 11 is elastic. When the cutting rod 7 moves to the end point of the front end, it is blocked by the obstruction block 12, and the traction rope 8 continues to move. The connecting rope 11 becomes longer and the elastic force becomes larger under the action of the tension. When the end point of the connecting rope 11 is close to the driving wheel 10, the elastic force can overcome the obstruction block 12, so that the cutting rod 7 passes through the obstruction block 12, and the cutting rod 7 immediately moves laterally to reach the innermost side of the bend of the dyed cloth, thereby avoiding the cutting rod 7 from moving laterally slowly, disrupting the bend of the dyed cloth, and causing the dyed cloth to become knotted. In addition, since the cutting rod 7 has a section of lateral movement in the vertical section 2 and moves in one direction in the horizontal section 1, the spacing between the two cutting rods 7 in the vertical section 2 is small, and the spacing between the two cutting rods 7 in the horizontal section 1 is large. After the dyed cloth enters the horizontal section 1, it will be appropriately loose. Even if the dyed cloth is excessively stacked in the horizontal section 1, it will become loose in the vertical section 2, thereby reducing the probability of creases.

[0028] In the second embodiment, since the traction rope 8 is immersed in the dye, in order to increase the reliability of the traction rope 8, please refer to Figure 4 On the basis of the first embodiment, the driving wheel 10 includes a rotating wheel 101, which is connected to the driving motor through a rotating shaft. The rotating shaft passes through the side wall of the vertical section 2. A driving groove 102 is provided on the outer side of the rotating wheel 101, and a suction block 104 corresponding to the driving groove 102 is provided on the traction rope 8. The suction block 104 is inserted into the driving groove 102 to increase the force between the driving wheel 10 and the traction rope 8, thereby ensuring that the traction rope 8 does not slip.

[0029] In order to further increase the acting force between the traction rope 8 and the driving wheel 10, a magnet 103 is provided in the rotating wheel 101, and a wedge iron 105 is filled in the suction block 104. The suction block 104 is sucked into the driving groove 102 to increase the acting force between the traction rope 8 and the driving wheel 10. Even if the traction rope 8 is in a loose state, the driving wheel 10 can still pull the traction rope 8 to move, thereby reducing the requirement for the tension of the traction rope 8. Since the traction rope 8 does not need to be tightened, there is no need to set a guide wheel 9 at the turning position, thereby reducing the number of guide wheels 9. In order to prevent the traction rope 8 from slipping, the position of the driving wheel 10 is the highest point of the traction rope 8, and baffles 106 are provided on both sides of the rotating wheel 101. In order to facilitate the installation and maintenance of the traction rope 8 and the guide wheel 9, both sides of the cloth storage tank are provided with openable inspection ports.

[0030] Embodiment 3, in order to adapt the running speed of the traction rope 8 to the moving speed of the dyed cloth, based on Embodiment 1 or Embodiment 2, refer to Figure 5 and Figure 6 , the front and rear sides of the connection between the horizontal section 1 and the cloth guide groove 4 are provided with monitoring components 13, which are relative to the direction of movement of the dyed cloth. The monitoring components 13 can sense the dyed cloth. When the dyed cloth is in contact with the front side ( Figure 5 When the monitoring component 13 (on the left side in the middle) contacts with the dyed cloth, it means that the dyed cloth is pulled into the cloth guide groove 4 from the front side, and the moving speed of the traction rope 8 is slow. The speed of the traction rope 8 increases by one level. If it contacts with the monitoring component 13 on the rear side, the speed of the traction rope 8 decreases by one level, until the front and rear monitoring components 13 are not in contact with the dyed cloth, and the dyed cloth is almost vertically pulled into the cloth guide groove 4. On the one hand, the speed is adapted to the traction speed of the dyed cloth, which reduces the tension on the dyed cloth and improves the quality of the dyed cloth. On the other hand, it can also prevent the cloth from rubbing against the connection between the cloth guide groove 4 and the vertical section 2 and causing damage.

[0031] The monitoring component 13 includes a rotating rod 131, which passes through the side wall of the horizontal section 1. The rotating rod 131 is fixedly connected to a rotating frame 133. The rotating frame 133 is provided with a sensing rope 132. One end of the sensing rope 132 is connected to a pressure sensor. Since the sensing rope 132 is thinner, the force between it and the dye liquid is smaller, which can effectively reduce the interference with the flow of the dye liquid. When the sensor connected to the sensing rope 132 senses a large pressure greater than the threshold value for a duration that exceeds the set time, it is determined that the dyed cloth is in contact with the monitoring component 13, and the rotating rod 131 is located within the projection of the connection between the cloth guide groove 4 and the vertical section 2.
