[0036] Refer to Figures 10 - 12, the material blocking component includes a strong magnet 71, a material blocking plate 72, a connecting plate 73 and a clamping block 74. Strong magnets 71 are installed at the rear ends of the yarn carrier cylinders 7. Connecting plates 73 that can slide back and forth on the electric rotating liquid spraying cylinder 6 are provided on the electric rotating liquid spraying cylinder 6. The connecting plate 73 is made of iron. When the yarn carrier cylinder 7 moves forward, the connecting plate 73 is attracted by the strong magnet 71 and moves forward together. A material blocking plate 72 is provided between the two connecting plates 73. The connecting plate 73 can rotate relative to the material blocking plate 72. A pair of clamping blocks 74 are slidably connected to the connecting plate 73. A return spring is fixedly connected between the clamping block 74 and the connecting plate 73. A pair of card slots 75 are opened at the front ends of the electric rotating liquid spraying cylinder 6. The rear sides of the clamping blocks 74 are provided with inclined surfaces III.

[0037] Reference Figure 1 and Figure 3 , it further includes a collection box 11, and the collection box 11 is fixedly connected to the front side of the bracket 1.

[0038] Initially, the electric clamping plate 102 clamps two yarn carriers 7 in the dyeing box 2. Two yarn carriers 7 in the dyeing box 2 are already sleeved with skeins of yarn to be dyed. The telescopic rod of the electric push rod is in the extended state, the compression spring on the extrusion rod 36 is in the stretched state, and the return spring is in the compressed state. The support plate 35 abuts against the limit frame 34 to support the limit frame 34 and the support block 32. The yarn carrier 7 is of a detachable design, and the number of yarn carriers 7 is more than four. First, control the fixed liquid spraying cylinder 5 and the electric rotating liquid spraying cylinder 6 to spray the dyeing liquid, so as to dye the skeins in the dyeing box 2. During the dyeing process, manually sleeve the other two yarn carriers 7 on two docking cylinders 33 respectively. The two docking cylinders 33 are respectively located between two pairs of belt conveyors 3. Then, sleeve two loops of skeins of yarn to be dyed on the front ends of the two pairs of belt conveyors 3 respectively. Control the belt conveyors 3 to convey the skeins backward and then sleeve the skeins. The push plate 4 can separate the skeins one by one. The sleeved skeins are also sleeved on the yarn carriers 7 on the docking cylinders 33, which is convenient for people to feed the materials. When the feeding of these two yarn carriers 7 is completed and the skeins in the dyeing box 2 are dyed, control the hydraulic cylinder 83 to drive the moving frame 82 to move forward, driving the door plate 8, the push block 93, the fixing plate 101, the electric clamping plate 102, the two yarn carriers 7 in the dyeing box 2, the strong magnet 71 and the dyed skeins to move forward. Since the limit block 91 is stuck in the limit groove 90 and the rear side of the limit block 91 is a straight surface, the door plate 8 will drive the limit block 91, the L-shaped plate 9, the electric push rod, the pushing rod 901, the inclined rod 92 and the L-shaped rod 95 to move forward together. Since the strong magnet 71 attracts the connecting plate 73, the strong magnet 71 drives the connecting plate 73, the baffle plate 72 and the clamping block 74 to move forward together. When the inclined rod 92 contacts the sliding plate 96, the inclined rod 92 squeezes the sliding plate 96 to move toward the side close to the L-shaped plate 9 in the vertical direction. The sliding plate 96 squeezes the L-shaped rod 95 to move toward the side close to the L-shaped plate 9 in the vertical direction. The L-shaped rod 95 then pushes the push block 93 to move toward the side close to the limit block 91 in the vertical direction. The push block 93 pushes the limit block 91 out of the limit groove 90. At this time, the moving frame 82, the door plate 8, the push block 93, the fixing plate 101, the electric clamping plate 102, the two yarn carriers 7 sleeved with dyed skeins, the strong magnet 71, the connecting plate 73, the baffle plate 72 and the clamping block 74 continue to move forward. The L-shaped plate 9 is separated from the door plate 8, and the L-shaped plate 9 and the pushing rod 901 stop moving forward. The skeins on these two yarn carriers 7 are blocked by the pushing rod 901, and the baffle plate 72 temporarily blocks the skeins, so that the skeins will not fall off temporarily. When the clamping block 74 moves to the clamping groove 75, the return spring restores and drives the clamping block 74 to snap into the clamping groove 75. The clamping block 74, the connecting plate 73 and the baffle plate 72 stop moving, while the moving frame 82, the door plate 8, the electric clamping plate 102, these two yarn carriers 7 and the strong magnet 71 continue to move forward. The strong magnet 71 is separated from the connecting plate 73, and the skeins on these two yarn carriers 7 fall downward into the collection box 11 for collection, with high unloading efficiency. When these two yarn carriers 7 are pulled out from the L-shaped plate 9,The electric clamping plate 102 can be controlled to loosen these two yarn carriers 7 and remove the yarn carriers 7. Then, control the electric moving seat 84 to move to the right, driving the hydraulic cylinder 83, the moving frame 82, the door panel 8, the electric clamping plate 102 and the pressing plate 37 to move to the right. The pressing plate 37 no longer presses the pressing rod 36, and the compression spring on the pressing rod 36 restores, driving the pressing rod 36 to move to the right. The pressing rod 36 presses the support plate 35 to move backward through the first inclined surface. The support plate 35 no longer supports the limiting frame 34. The pressing plate 37 then presses the limiting frame 34 to move downward through the second inclined surface. The limiting frame 34 pushes the support block 32 to move downward. Under the guiding action of the arc-shaped guiding frame 31, the two support blocks 32 on the same arc-shaped guiding frame 31 move downward while moving toward each other. The belt conveyor 3 moves together with the support block 32. The two belt conveyors 3 of the same pair move toward the middle and move to directly below the yarn carriers 7 on the docking cylinder 33, so that the twisted yarn on the belt conveyor 3 is sleeved on these two yarn carriers 7. These twisted yarns are separated from the belt conveyor 3. When the electric clamping plate 102 is aligned with these two yarn carriers 7 front and back, control the hydraulic cylinder 83 to drive the moving frame 82, the door panel 8 and the electric clamping plate 102 to move backward, and control the electric clamping plate 102 to clamp these two yarn carriers 7. Similarly, controlling the hydraulic cylinder 83 and the electric moving seat 84 can make the moving frame 82, the door panel 8, the electric clamping plate 102 and these two yarn carriers 7 and the twisted yarn to be dyed move forward and then to the left. The pressing plate 37 moves leftward to reset with the electric moving seat 84, and control the electric push rod to drive the two pushing rods 901 to move away from each other in the left-right direction to prevent the pushing rods 901 from blocking the twisted yarn. The moving frame 82, the door panel 8, the electric clamping plate 102 and these two yarn carriers 7 and the twisted yarn to be dyed move backward to reset again, moving these two yarn carriers 7 and the twisted yarn to be dyed into the dyeing box 2. When the door panel 8 contacts the limit block 91, the door panel 8 will press the limit block 91 to retract. When the limit block 91 is aligned with the limit groove 90, the limit block 91 is reset by the return spring 94, and the limit block 91 is snapped into the limit groove 90, making the L-shaped plate 9 move backward to the initial position together with the door panel 8. At the same time, the strong magnets 71 on these two yarn carriers 7 push the connecting plate 73. Since the rear side of the clamping block 74 is the third inclined surface, the clamping block 74 will retract when being pressed, and the clamping block 74 leaves the clamping groove 75, so that the connecting plate 73 and the baffle plate 72 move backward to reset together. The pressing plate 37 moves leftward to reset and no longer presses the limiting frame 34. The limiting frame 34 rises and resets through the compression spring. Similarly, the support block 32 and the belt conveyor 3 are reset to the initial position. And the pressing plate 37 moving leftward will push the pressing rod 36 to move leftward to reset. The pressing rod 36 no longer presses the support plate 35, and the support plate 35 moves forward to reset and supports the limiting frame 34 again. At this time, the twisted yarn in the dyeing box 2 can be dyed, and the feeding work continues at the same time. In this way, the feeding and dyeing processes are carried out simultaneously, and the discharging speed is fast. There is no need to manually remove the dyed twisted yarn one by one, saving operation time and improving the working efficiency of dyeing.
