DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1-Figure 8A layer dyeing production system for fabrics shown in the figure comprises a layer dyeing cabinet 1, a circular guide rail 2 and a hanger 5, the circular guide rail 2 is provided with two straight sections 21, one of the straight sections 21 passes through the layer dyeing cabinet 1, a running trolley 3 is installed on the circular guide rail 2, the running trolley 3 can circulate along the circular guide rail 2, a lifting device 4 is installed below the running trolley 3, the hanger 5 comprises a hanging mechanism 51 and a fabric hanger 52, the hanging mechanism 51 is connected to the lifting device 4 by transmission, the fabric hanger 52 is installed below the hanging mechanism 51, and a vertically installed fabric to be dyed is clamped on the fabric hanger 52, a plurality of dye barrels 6 are installed in the layer dyeing cabinet 1, and the plurality of dye barrels 6 are arranged in a straight line along the travel direction of the running trolley 3, the running trolley 3 carries the fabric to be dyed into the layer dyeing cabinet 1, and when it runs to each dye barrel 6, The lifting device 4 can drive the fabric hanger 52 to complete a lifting movement process. After the fabric hanger 52 moves downward, the fabric is immersed in the dye barrel 6 for dyeing. As the running trolley 3 passes through each dye barrel 6 one by one, layers of different shades of color can be formed on the fabric. Another straight section 21 of the annular guide rail 2 is provided with a collecting area 22 and a loading area 23. The dyed fabric is carried by the running trolley 3 to the collecting area 22. The workers complete the fabric disassembly and collecting operations. Then the running trolley 3 continues to move forward to the loading area 23. The workers in the loading area 23 complete the installation of the new fabric. The present invention can realize the streamlined automatic dyeing operation of the fabric, and has the advantages of high degree of automation and easy operation. The annular guide rail 2 of the present invention can be designed to install multiple running trolleys 3 to carry fabrics to achieve uninterrupted dyeing operations.

[0032] like Figure 3-Figure 5 As shown, the drawings of the present invention design three dye barrels 6 for dyeing operations. In practice, the number of dye barrels 6 can be set according to the number of layers required. Each dye barrel 6 contains dye liquid 61 with different liquid levels. A liquid level controller 62 is installed in each dye barrel 6. The liquid level controller 62 can control the liquid level of the dye liquid 61. When the liquid level of the dye liquid 61 drops, it can be replenished in time. Along the direction of travel of the running trolley 3, the liquid level of the dye liquid 61 in the dye barrel 6 decreases successively. Along the direction of travel of the running trolley 3, the color concentration of the dye liquid 61 in the dye barrel 6 increases successively. The dyeing principle is as follows, Figure 3 As shown, this is the first dye barrel 6, and the liquid level in the dye barrel 6 is the highest. In the present invention, the height of the fabric is kept consistent each time it is dropped. In the first dye barrel 6, the fabric is completely immersed. Since the dye color of the first dye barrel is the lightest, the fabric can be completely immersed in a light base color. Figure 4 As shown, this is the second dye bucket 6. The liquid level in the dye bucket 6 is centered, and the dye color is also centered. In the second dye bucket 6, only two-thirds of the fabric is immersed, so the first stratification can be formed. Figure 5As shown, this is the third dye barrel 6, the liquid level in the dye barrel 6 is the lowest and the dye color is the darkest. In the second dye barrel 6, only one-third of the fabric is immersed, so a second layer can be formed. After the fabric comes out of the third dye barrel 6, three layers from light to dark can be formed on the fabric, meeting the layered dyeing requirements on the fabric.

[0033] like Figure 1 As shown, a plurality of movable doors 11 are installed on the front of the layer dyeing cabinet 1. The number of the movable doors 11 corresponds to the dye barrel 6. The dye barrel 6 is loaded into the layer dyeing cabinet 1 through the movable doors 11. Both the movable doors 11 and the dye barrel 6 are made of transparent materials, so that the liquid level of the dye liquid 61 and the dyeing condition of the fabric can be observed in real time.

[0034] like Figure 3 and Figure 8 As shown, the lifting device 4 includes a lifting frame 41, a screw 42, a lifting beam 44 and a first motor 45. The lifting frame 41 is fixedly connected to the bottom of the running trolley 3, so that the lifting device 4 moves with the running trolley 3. The screw 42 is rotatably installed in the lifting frame 41. Guide columns 43 are fixedly installed on both sides of the screw 42. The lifting beam 44 is installed on the two guide columns 43 and is threadedly connected with the screw 42. The first motor 45 is installed on the top of the lifting frame 41. The output end of the first motor 45 is connected to the screw 42 to drive the rotation of the screw 42. The first motor 45 can be a battery. When the screw 42 is powered by a motor and rotates, the lifting beam 44 is guided by the guide column 43 so that the lifting beam 44 can move up and down. The suspension mechanism 51 is connected to the lifting beam 44, so that the suspension mechanism 51 and the fabric hanger 52 installed thereunder can move up and down. At each dye barrel 6 position, the lifting device 4 is started twice. The first time is to lower the fabric so that it enters the dye barrel 6 for dyeing, and the second time is to raise the fabric to avoid the dye barrel 6 so that the operation of the running trolley 3 is not interfered with. When descending, the lifting beam 44 descends to the lower limit position, and when rising, the lifting beam 44 rises to the upper limit position.

[0035] like Figure 3 As shown, the suspension mechanism 51 includes a suspension box 511 and a suspension rod 512. The suspension box 511 is fixedly connected to the side wall of the lifting beam 44. The suspension rod 512 is installed through the suspension box 511. The suspension rod 512 is installed vertically. The fabric hanger 52 is fixedly connected to the bottom of the suspension rod 512. Under the action of the above-mentioned connection structure, the fabric hanger 52 can carry the fabric and move up and down with the lifting beam 44.

[0036] like Figure 3 As shown, a plurality of cloth clips 521 are installed in the fabric hanger 52, and the fabrics are installed upright through the cloth clips 521. A plurality of parallelly installed fabrics are clamped in the fabric hanger 52, so that the dyeing operation of multiple fabrics can be completed at one time to improve the dyeing efficiency.

[0037] In order to make the running trolley 3 accurately land in the dye barrel 6 area, as Figure 6 As shown, an in-place detector 311 is fixedly installed on the side of the running trolley 3, and a plurality of sensor stickers 312 are installed in the layer dyeing cabinet 1. Each sensor sticker 312 corresponds to a dye barrel 6. Each time the in-place detector 311 moves to the position of the sensor sticker 312, the running trolley 3 will stop to perform a dyeing operation.

[0038] like Figure 7 As shown, the suspension box 511 is provided with an inner cavity 5111, and a piston 513 and a spring 514 are installed in the inner cavity 5111. The piston 513 is fixedly connected to the outer wall of the suspension rod 512 and is installed to match the size of the inner cavity 5111. One end of the spring 514 is connected to the bottom of the piston 513, and the other end is connected to the bottom of the inner cavity 5111. The piston 513 plays a role in guiding the movement of the suspension rod 512, so that it can only move vertically. The spring 514 plays a role in elastically supporting the piston 513 and the suspension rod 512, forming an upward thrust for the suspension rod 512. The layer dyeing cabinet 1 is installed with some A rhythmic dyeing mechanism 7 is provided to cooperate with the elastic mounting structure of the suspension rod 512. The rhythmic dyeing mechanism 7 is arranged in one-to-one correspondence with the dye barrel 6. The rhythmic dyeing mechanism 7 can drive the suspension rod 512 to move up and down. The rhythmic dyeing mechanism 7 includes a motor frame 71, a second motor 72 and a telescopic avoidance component 74. The second motor 72 is fixed on the motor frame 71. A cam 73 is connected to the output end of the second motor 72. The motor frame 71 is a T-shaped frame. The telescopic avoidance component 74 includes a telescopic push cylinder 741 and a limit frame 742. The telescopic push cylinder 741 is installed horizontally. The motor frame 71 is connected to the telescopic The piston rod end of the telescopic push cylinder 741 and the limit frame 742 block the movement path of the motor frame 71. When the piston rod end of the telescopic push cylinder 741 is extended, the limit frame 742 contacts the motor frame 71, and the cam 73 moves just above the suspension rod 512. The cam 73 is provided with a protrusion. The second motor 72 drives the cam 73 to rotate. When the top of the suspension rod 512 contacts the protrusion, the suspension rod 512 can be pushed downward. As the cam 73 rotates, the suspension rod 512 and the fabric installed below can be rhythmically lifted and lowered. The amplitude of this rhythmic lifting is small, but it can accelerate the dyeing effect, and Since the stratification line rises and falls at the top of the liquid surface, the stratification line will be blurred, so that a smooth color change effect is formed between the color layers. The rhythmic dyeing mechanism 7 is only used during dyeing operations, so as not to affect the lifting and lowering movement of the sling 5. When the piston rod of the telescopic push cylinder 741 retracts, the cam 73 can avoid the lifting and lowering movement route of the suspension mechanism 51, so as not to affect the lifting and lowering movement of the sling 5. The rhythmic dyeing mechanism 7 starts the operation after the sling 5 is lowered into place. Before the sling 5 rises again, the piston rod of the telescopic push cylinder 741 must be retracted so that the cam 73 can avoid the rise of the sling 5.

[0039] A layer dyeing production method for fabrics is implemented by using a layer dyeing production system for fabrics, and comprises the following steps:

[0040] (a) The fabric is vertically hoisted onto the sling 5 in the loading area 23. As the running trolley 3 moves forward, the fabric moves along the circular guide rail with the sling 5;

[0041] (b) The fabric flows into the layer dyeing cabinet 1. Several dye barrels 6 are installed in the layer dyeing cabinet 1 along the direction of travel of the running trolley 3. The fabric stays at each dye barrel 6 one by one, and the fabric is controlled to descend to the same depth by the lifting device 4. Each dye barrel 6 has different dye color depths and liquid level heights of the dye liquid 61. The first dye barrel 6 has the highest liquid level and the lightest color. Then, along the direction of travel of the running trolley 3, the color of the dye liquid 61 gradually deepens, and the liquid level of the dye liquid 61 gradually decreases. After the fabric passes through all the above-mentioned dye barrels 6 one by one, a layered effect from light to dark is formed from top to bottom. A rhythmic dyeing mechanism 7 is installed at each dye barrel 6. The rhythmic dyeing mechanism 7 can drive the fabric to rise and fall slightly to blur the boundaries between the color layers, so that a smooth color change effect is formed between the color layers.

[0042] (c) The finished fabric is circulated and output from the layer dyeing cabinet 1, and then runs to the material receiving area 22 and is disassembled and recycled.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
