Description

Technical Field

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

[0002] With the continuous increase in the types of fabrics, wool sweaters have become a synonym for a category of products, that is, they are used to generally refer to "knitted wool sweaters" or "woolen knitted products". Woolen knitted products refer to fabrics mainly woven from yarns spun from animal hair fibers such as wool, cashmere, or rabbit hair.

[0003] The invention patent with the authorization announcement number CN105986384B discloses an anti-pilling device for a drum-type dyeing machine suitable for dyeing wool sweaters, leather, etc. A dial rod is provided on the inner circumferential wall of the drum. The horizontal plane where the outer tangent of the contact point of the dial rod and the inner circumferential wall of the drum is located forms an acute angle with the dial rod; when a part of the dial rod and another part of the dial rod rotate in the same direction in the drum and pass through the same position, the orientations of the dial rods are opposite.

[0004] However, after the actual application of the above anti-pilling device by those skilled in the art, it is found that there are still some drawbacks. The more obvious one is that although the setting of the dial rod can avoid the occurrence of pilling and fuzzing of the dyed wool sweaters, when the wool sweaters to be dyed are added into the drum from the inlet, the existence of multiple dial rods will significantly block the forward and backward movement of the wool sweaters inside the drum, thus making it difficult for the wool sweaters to move from the middle of the drum cavity to both ends of the drum cavity, significantly increasing the feeding difficulty. In addition, when the dyed wool sweaters are taken out from the inlet, the wool sweaters will be blocked or even hooked by the dial rods, thus increasing the discharging difficulty of the wool sweaters. It not only requires wasting more manpower for processing but also significantly reduces the dyeing efficiency of the wool sweaters.

[0005] Therefore, it is very necessary to invent an anti-pilling device for a drum-type 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.

DETAILED DESCRIPTION

[0029] 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.

[0030] The present invention provides Figures 1 - 5 The anti-pilling device of a drum dyeing machine shown in the figure comprises a bracket 1, a dyeing mechanism 3 is arranged on the left side inside the bracket 1, a hydraulic driving mechanism 4 and a water collecting and supporting mechanism 2 are arranged on the right side inside the bracket 1, the water collecting and supporting mechanism 2 is located below the hydraulic driving mechanism 4, a plurality of groups of trigger mechanisms 5 are evenly arranged on the left end of the hydraulic driving mechanism 4, and two groups of toggle mechanisms 6 are arranged inside any group of the trigger mechanisms 5;

[0031] The hydraulic drive mechanism 4 drives the trigger mechanism 5 and the retracted toggle mechanism 6 into the dyeing mechanism 3 and seals the right end opening of the dyeing mechanism 3. The hydraulic drive mechanism 4 triggers the trigger mechanism 5, thereby causing multiple toggle mechanisms 6 to unfold. The hydraulic drive mechanism 4 releases the trigger of the trigger mechanism 5, causing the toggle mechanism 6 to be retracted again. At the same time, the dyeing mechanism 3 drives the toggle mechanism 6 to rotate through the trigger mechanism 5, thereby causing the woolen sweater to fall on the top of the water collecting and supporting mechanism 2.

[0032] As Figure 2 shown, the water collecting and supporting mechanism 2 includes a waste water collecting tank 21, a supporting mesh plate 22 and a drain pipe 23. Among them, the waste water collecting tank 21 is fixedly arranged at the bottom right end inside the bracket 1, the supporting mesh plate 22 is fixedly arranged on the top of the waste water collecting tank 21, and the drain pipe 23 is fixedly arranged through the right end at the rear of the waste water collecting tank 21.

[0033] By setting the above structure, it is convenient for the dyeing waste liquid to pass through the supporting mesh plate 22 and fall into the waste water collecting tank 21 and be output through the drain pipe 23, while the woolen sweater accumulates on the top of the supporting mesh plate 22.

[0034] As Figure 3 shown, the dyeing mechanism 3 includes a rotating pipe 31, a first motor 32, a dyeing drum 33, a guide groove 34, a base 35, a support roller 36, a sealing box 37 and a fixing rod 38. Among them, the rotating pipe 31 penetrates through the left side of the bracket 1 and is rotationally connected to the bracket 1 through a bearing. The first motor 32 is fixedly arranged at the top left of the bracket 1. The rotating pipe 31 is drivingly connected to the first motor 32 through two meshing transmission gears. The dyeing drum 33 is fixedly sleeved on the outer right end of the rotating pipe 31. A feeding port is arranged on the front of the dyeing drum 33, and a sealing door is arranged outside the feeding port. A plurality of guide grooves 34 are arranged, and the plurality of guide grooves 34 are evenly opened on the inner side of the dyeing drum 33. The base 35 is fixedly arranged at the bottom inside the bracket 1. A plurality of support rollers 36 are arranged, and the plurality of support rollers 36 are rotationally nested on the top of the base 35 through bearings and are all in contact with the bottom of the dyeing drum 33.

A dyeing liquid input pipe and a steam input pipe are fixedly arranged through the front of the sealing box 37, and one-way valves are arranged on both the dyeing liquid input pipe and the steam input pipe.

[0035] By setting the above structure, it is convenient to add the woolen sweaters to be dyed into the inside of the dyeing drum 33 through the front feed port of the rotating tube 31. Subsequently, the dyeing solution and steam are input into the inside of the sealing box 37 through the dyeing solution input pipe and the steam input pipe. The dyeing solution and steam enter the inside of the dyeing drum 33 through the rotating tube 31. After the input of the dyeing solution and steam is completed, the first motor 32 is started. 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 tops of multiple support rollers 36, and then the woolen sweater dyeing operation begins.

[0036] It should be noted that the front feed port of the rotating tube 31 and the support roller 36 are not collinear in the vertical direction, so as to avoid the sealing door at the feed port position from causing obstruction when the rotating tube 31 rotates.

[0037] As Figure 2 shown, the hydraulic drive mechanism 4 includes a hydraulic cylinder 41, a push plate 42, a movable ring 43, a moving shaft 44, a first return spring 45 and a sealing disc 46. Among them, the hydraulic cylinder 41 is fixedly arranged on the right side of the bracket 1 and its output shaft is fixedly connected to the push plate 42. The movable ring 43 is rotatably arranged on the left side of the push plate 42 through a bearing. The moving shaft 44 slidably penetrates the push plate 42. The first return spring 45 is sleeved on the outside of the moving shaft 44. One end of the first return spring 45 is rotatably connected to the push plate 42 through a bearing, and the other end is fixedly connected to the sealing disc 46 through a bearing. The sealing disc 46 is rotatably sleeved on the left end of the moving shaft 44 through a bearing.

[0038] By setting the above structure, it is convenient to drive the push plate 42 to move leftward by the hydraulic cylinder 41. The push plate 42 drives the movable ring 43 to move leftward synchronously. At the same time, the sealing disc 46 is driven to move leftward by the first return spring 45, and the sealing disc 46 drives multiple trigger mechanisms 5 to move leftward.

[0039] As Figure 4 shown, the trigger mechanism 5 includes a mounting plate 51, a guide rail 52, an avoidance groove 53, an extension rod 54, a threaded sleeve 55, a sliding rod 56, an end plate 57 and a second return spring 58. Among them, the mounting plate 51 is fixedly arranged on the left side of the sealing disc 46 and is slidably attached to the inner wall of the dyeing drum 33. The guide rail 52 is fixedly arranged on the outside of the mounting plate 51 and is slidably arranged inside the guide groove 34. The avoidance groove 53 is opened at the top of the mounting plate 51. The extension rod 54 is slidably arranged inside the avoidance groove 53. The threaded sleeve 55 is fixedly arranged at the end of the extension rod 54. The sliding rod 56 is slidably arranged inside the mounting plate 51 and is fixedly connected to the extension rod 54. The end plate 57 is fixedly arranged at the end of the sliding rod 56. The second return spring 58 is sleeved on the outside of the sliding rod 56 and is fixedly connected between the sealing disc 46 and the end plate 57.

[0040] 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.

[0041] 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.

[0042] By setting the above structure, the one-way screw 64 is driven to rotate during the left movement of the threaded sleeve 55, and the one-way screw 64 rotates to drive the mounting sleeve 65 to rotate. 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.

[0043] The present invention also discloses a method for using the anti-pilling device of a drum dyeing machine, and the method specifically comprises the following steps:

[0044] S1, the hydraulic cylinder 41 drives the push plate 42 to move leftward, the push plate 42 drives the movable ring 43 to move leftward synchronously, and at the same time, the sealing plate 46 is driven to move leftward by the first return spring 45, and the sealing plate 46 drives the multiple groups of trigger mechanisms 5 to move leftward;

[0045] S2, as the sealing disk 46 continues to move left, the sealing disk 46 seals the opening at the right end of the dyeing drum 33. 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;

[0046] 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;

[0047] 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. 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. Multiple V-shaped levers 68 are unfolded due to the rotation, and then the hydraulic cylinder 41 is stopped until the dyeing is completed.

[0048] 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;

[0049] 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;

[0050] 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.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
