Description

Technical Field

[0001] The invention relates to the technical field of dyeing equipment, in particular to an anti-pilling device of a drum-type dyeing machine. Background Art

[0002] With the increasing variety of fabrics, wool sweaters have become a synonym for a type of product, which is used to refer to "knitted sweaters" or "wool knitwear". Wool knitwear refers to fabrics made mainly from animal hair fibers such as wool, cashmere or rabbit hair, which are spun into yarns as the main raw materials.

[0003] The invention patent with authorization announcement number CN105986384B discloses an anti-pilling device for a drum dyeing machine suitable for dyeing wool sweaters, leather, etc. A lever is provided on the inner circumferential wall of the drum, and the horizontal plane where the tangent line of the contact point between the lever and the inner circumferential wall of the drum is located forms an acute angle with the lever; one part of the lever and the other part of the lever rotate in the same direction of the drum, and when passing the same position, the levers are in opposite directions.

[0004] However, after actual application by technicians skilled in the art, it was found that the above-mentioned anti-pilling device still has some shortcomings. The most obvious one is that although the setting of the lever can prevent the wool sweater from pilling after dyeing, when the wool sweater to be dyed is added to the drum from the entrance, the presence of multiple levers will cause obvious obstruction to the forward and backward movement of the wool sweater in the drum, thereby making it difficult for the wool sweater to move from the middle of the drum cavity to the two ends of the drum cavity, which significantly increases the difficulty of feeding. In addition, when the dyed wool sweater is taken out from the entrance, the wool sweater will be blocked or even hooked by the lever, thereby increasing the difficulty of discharging the wool sweater, requiring more manpower to handle and significantly reducing the dyeing efficiency of the wool sweater.

[0005] Therefore, it is necessary to invent an anti-pilling device for a drum dyeing machine to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide an anti-pilling device for a drum dyeing machine, which is provided with a water collecting and supporting mechanism, a dyeing mechanism, a hydraulic driving mechanism, a triggering mechanism and a toggle mechanism, so that the hydraulic driving mechanism drives the triggering mechanism and the toggle mechanism in the storage state to enter the dyeing mechanism and seal the opening at the right end of the dyeing mechanism. After the wool sweater to be dyed is loaded, the hydraulic driving mechanism triggers the triggering mechanism, thereby expanding multiple groups of toggle mechanisms. When the wool sweater is unloaded after dyeing, the hydraulic driving mechanism releases the triggering mechanism, so that the toggle mechanism is stored again. At the same time, the dyeing mechanism drives the toggle mechanism to rotate through the triggering mechanism, thereby The sweater falls on the top of the water collecting and supporting mechanism to solve the problem that although the setting of the lever proposed in the above background technology can avoid the pilling and fuzzing of the wool sweater after dyeing, when the wool sweater to be dyed is added into the drum from the entrance, the existence of multiple levers will cause obvious obstruction to the forward and backward movement of the wool sweater in the drum, thereby making it difficult for the wool sweater to move from the middle of the drum cavity to the two ends of the drum cavity, which significantly increases the difficulty of feeding.

[0028] By setting the above structure, the movable ring 43 contacts the end plate 57 due to continuous leftward movement. Subsequently, as the movable ring 43 continues to move leftward, the end plate 57 compresses the second return spring 58, and at the same time drives the threaded sleeve 55 to move leftward through the sliding rod 56 and the extension rod 54. During the leftward movement of the threaded sleeve 55, the one-way screw 64 is driven to rotate.

[0029] like Figure 4 As shown, the shifting mechanism 6 includes a U-shaped frame 61, a gear ring 62, a mounting shaft 63, a one-way screw 64, a mounting sleeve 65, an intermediate shaft 66, a bevel gear 67 and a V-shaped shifting rod 68, wherein the U-shaped frame 61 is fixedly arranged on the inner side of the mounting plate 51, the gear ring 62 is fixedly arranged on the inner side of the U-shaped frame 61, the mounting shaft 63 passes through one side of the U-shaped frame 61 and is rotatably connected to the U-shaped frame 61 through a bearing, the one-way screw 64 passes through the other side of the U-shaped frame 61 and is rotatably connected to the U-shaped frame 61 through a bearing, the one-way screw 64 is threadedly connected to the inner side of an adjacent threaded sleeve 55, the mounting sleeve 65 is fixedly arranged between the mounting shaft 63 and the one-way screw 64, the intermediate shaft 66 is rotatably arranged on the inner side of the mounting sleeve 65 through a bearing, the bevel gear 67 is fixedly arranged at one end of the intermediate shaft 66 and meshes with the gear ring 62, and the V-shaped shifting rod 68 is fixedly arranged at the other end of the intermediate shaft 66.

When the mounting sleeve 65 rotates, it drives the intermediate shaft 66 to revolve around the one-way screw 64 as the axis. During the revolution of the intermediate shaft 66, the gear ring 62 drives the intermediate shaft 66 to rotate through the bevel gear 67. When the intermediate shaft 66 rotates, it drives the V-shaped lever 68 to rotate synchronously, so that the V-shaped lever 68 is unfolded to the working state required for the dyeing operation. In addition, during the output of the dyeing waste liquid and the wool sweater, the dyeing drum 33 drives the mounting plate 51 to rotate counterclockwise through the guide groove 34 and the guide rail 52. When the mounting plate 51 rotates counterclockwise, it drives the toggle mechanism 6 to rotate synchronously counterclockwise. During the rotation of the toggle mechanism 6, the wool sweater hooked by the V-shaped lever 68 slides down along the V-shaped lever 68 under the influence of gravity and accumulates on the top of the supporting mesh plate 22, so that the hooked wool sweater is automatically discharged.

At this time, due to the obstruction of the dyeing drum 33, the sealing disk 46 cannot continue to move left. Subsequently, as the push plate 42 continues to move left, the first return spring 45 is compressed by the push plate 42, and the movable ring 43 moves closer to the end plate 57; S3, adding the wool sweater to be dyed into the dyeing drum 33 through the front feeding port of the rotating tube 31, and then inputting the dye liquid and steam into the sealing box 37 through the dye liquid input pipe and the steam input pipe, and the dye liquid and steam enter the dyeing drum 33 through the rotating tube 31. After the dye liquid and steam are input, start the first motor 32, and the first motor 32 drives the rotating tube 31 to rotate through the transmission gear. When the rotating tube 31 rotates, it drives the dyeing drum 33 to rotate counterclockwise on the top of the multiple supporting rollers 36, and then the wool sweater dyeing operation starts; S4, the movable ring 43 contacts the end plate 57 due to the continuous leftward movement. Subsequently, as the movable ring 43 continues to move leftward, the end plate 57 compresses the second return spring 58, and at the same time drives the threaded sleeve 55 to move leftward through the sliding rod 56 and the extension rod 54. During the leftward movement of the threaded sleeve 55, the one-way screw 64 is driven to rotate. When the one-way screw 64 rotates, the installation sleeve 65 is driven to rotate. When the installation sleeve 65 rotates, the intermediate shaft 66 is driven to revolve around the one-way screw 64 as the axis.

When the intermediate shaft 66 rotates, it drives the V-shaped lever 68 to rotate synchronously. Multiple V-shaped levers 68 are unfolded due to the rotation, and then the hydraulic cylinder 41 is stopped until the dyeing is completed. S5, after dyeing is completed, the hydraulic cylinder 41 drives the movable ring 43 to move rightward and reset through the push plate 42, the trigger mechanism 5 is reset synchronously with the movable ring 43, and the deployed toggle mechanism 6 is reset synchronously under the driving of the reset trigger mechanism 5; S6, the compressed first return spring 45 is returned to its original position, and subsequently, as the push plate 42 continues to move rightward, the push plate 42 drives the sealing plate 46 to move rightward through the first return spring 45, thereby releasing the seal of the right end opening of the dyeing drum 33, and at this time, the dyeing waste liquid inside the dyeing drum 33 and the dyed wool sweater fall from the right end opening of the dyeing drum 33 to the top of the supporting mesh plate 22, the dyeing waste liquid passes through the supporting mesh plate 22 and falls into the wastewater collecting tank 21 and is discharged through the drain pipe 23, and the wool sweater is accumulated on the top of the supporting mesh plate 22; S7. During the output of dyeing waste liquid and wool sweater, the dyeing drum 33 drives the mounting plate 51 to rotate counterclockwise through the guide groove 34 and the guide rail 52. When the mounting plate 51 rotates counterclockwise, it drives the toggle mechanism 6 to rotate counterclockwise synchronously. During the rotation of the toggle mechanism 6, the wool sweater hooked by the V-shaped lever 68 slides down along the V-shaped lever 68 under the influence of gravity and accumulates on the top of the supporting mesh plate 22. After the movable ring 43 moves to the right to the initial position, the hydraulic cylinder 41 is stopped.
