[0004] However, after actual application by technicians in this field, it was found that the above device still has some shortcomings. The most obvious one is that after dyeing is completed, the operator needs to discharge the dyeing waste liquid through the drainage hole first, and then open the material door and discharge the dyed wool sweater from the material inlet. The overall operation is time-consuming and due to the size limitation of the material inlet, the discharge efficiency of the wool sweater is not ideal. In addition, when the wool sweater is discharged, it will absorb more dye liquid, so its weight will increase, which will not only further increase the difficulty of discharging, but also easily cause the dyeing waste liquid to enter the working environment and cause pollution.

In the subsequent process in which the power unit drives the wool sweater carrying mechanism to rotate and move upward, the shielding and exporting mechanism shields the continuously rotating wool sweater carrying mechanism, and the wool sweater carrying mechanism throws out the residual water in the wool sweater to complete the recovery of the residual dye liquid. Then the blocking mechanism blocks the wool sweater carrying mechanism, and the power unit The wool sweater carrying mechanism is triggered, and the wool sweater inside the wool sweater carrying mechanism falls on the top of the shielding and exporting mechanism under the action of centrifugal force and is discharged, so as to solve the problem proposed in the above background technology that after dyeing is completed, the operator needs to discharge the dyeing waste liquid through the drainage hole first, and then open the material door and discharge the dyed wool sweater from the material inlet. The overall operation is time-consuming and due to the size limitation of the material inlet, the discharge efficiency of the wool sweater is not ideal.

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.

[0019] The present invention provides Figure 1-Figure 5 A wool sweater dyeing machine shown in the figure comprises a shell 1, a dyeing mechanism 2 is arranged at the bottom of the inner side of the shell 1, a shielding and exporting mechanism 3 is arranged at the outer side of the dyeing mechanism 2, a power unit 4 is arranged at the top of the inner side of the shell 1, a wool sweater carrying mechanism 5 is arranged at the bottom of the power unit 4, and a blocking mechanism 6 is arranged at the outer side of the power unit 4; The power unit 4 drives the sweater carrying mechanism 5 on which the sweater to be dyed is placed to move downward into the dyeing mechanism 2 for dyeing, and at the same time, the sweater carrying mechanism 5 is connected to the shielding and exporting mechanism 3. In the subsequent process in which the power unit 4 drives the sweater carrying mechanism 5 to rotate and move upward, the shielding and exporting mechanism 3 shields the continuously rotating sweater carrying mechanism 5, and the sweater carrying mechanism 5 throws out the residual water in the sweater. Then the blocking mechanism 6 blocks the sweater carrying mechanism 5, and the power unit 4 triggers the sweater carrying mechanism 5. The sweater inside the sweater carrying mechanism 5 falls on the top of the shielding and exporting mechanism 3 under the action of centrifugal force and is exported.

[0020] like Figure 3 As shown, the dyeing mechanism 2 includes a dyeing cylinder 21 and a screen plate 22, wherein the dyeing cylinder 21 is fixedly arranged at the inner bottom of the outer shell 1, and the screen plate 22 is rotatably arranged at the inner bottom of the dyeing cylinder 21 through a bearing, a steam input pipe is fixedly penetrated on the left side of the dyeing cylinder 21, and a dye liquid input pipe and a dye liquid output pipe are fixedly penetrated on the right side of the screen plate 22.

[0021] like Figure 3 As shown, the shielding and exporting mechanism 3 includes a first fixed ring 31, a shielding sleeve 32, a first annular magnet 33, a second fixed ring 34, a first guide rod 35 and a guide plate 36, wherein the first fixed ring 31 and the shielding sleeve 32 are sequentially sleeved and arranged on the outside of the dyeing cylinder 21 from bottom to top, the first fixed ring 31 is fixedly connected to the dyeing cylinder 21, the shielding sleeve 32 is slidably connected to the dyeing cylinder 21, the first annular magnet 33 is rotatably arranged on the top of the shielding sleeve 32 through a bearing, the second fixed ring 34 is fixedly sleeved and arranged on the outside of the shielding sleeve 32, the first guide rod 35 slides through the second fixed ring 34 and is fixedly arranged on the top of the first fixed ring 31, and the guide plate 36 is slidably sleeved and arranged on the outside of the shielding sleeve 32 and is fixedly arranged on the top of the first guide rod 35.

[0022] By setting the above structure, when the first annular magnet 33 moves upward, the second fixing ring 34 is driven by the shielding sleeve 32 to move upward synchronously along the first guide rod 35 until the second fixing ring 34 is driven by the shielding sleeve 32 to fit with the bottom of the guide plate 36. At this time, due to the obstruction of the guide plate 36, when the subsequent wool sweater carrying mechanism 5 continues to rise, the second annular magnet 52 is detached from the top of the first annular magnet 33, and then the shielding sleeve 32 is reset under the action of gravity.

[0023] like Figure 4 As shown, the power unit 4 includes a screw 41, a forward and reverse motor 42, a square slot 43, a lifting frame 44, a connecting spring 45, a sliding sleeve 46 and a disc 47, wherein the screw 41 passes through the housing 1 and is rotatably connected to the housing 1 through a bearing, the forward and reverse motor 42 is fixedly arranged at the top of the housing 1 and is transmission-connected to the screw 41, the square slot 43 is opened at the bottom of the screw 41, the lifting frame 44 is sleeved on the outside of the screw 41 and is transmission-connected thereto, two connecting springs 45 are provided and are respectively fixedly connected to the two sides of the top of the sliding sleeve 46, the top ends of the two connecting springs 45 are fixedly connected to the inner wall of the lifting frame 44, the sliding sleeve 46 slides through the inner wall of the lifting frame 44 and extends to the bottom of the lifting frame 44, the disc 47 is fixedly sleeved on the outer bottom of the lifting frame 44, and a movable ring is rotatably provided at the bottom of the disc 47 through a bearing.

[0024] By setting the above structure, the forward and reverse motor 42 can drive the screw 41 to rotate. When the screw 41 rotates, it drives the lifting frame 44 to descend. When the lifting frame 44 descends, it drives the disc 47 to descend. At the same time, the sliding sleeve 46 is driven to descend through the connecting spring 45. When the sliding sleeve 46 descends, it drives the sweater carrying mechanism 5 to descend as a whole.

[0025] like Figure 5As shown, the sweater carrying mechanism 5 includes an end plate 51, a second annular magnet 52, a connecting shaft 53, a square shaft 54, a bottom plate 55, a second guide rod 56, a net tube 57, a limit housing 58 and a T-shaped rod 59, wherein the end plate 51 is rotatably arranged at the bottom end of the sliding sleeve 46 through a bearing, the second annular magnet 52 is rotatably sleeved and arranged on the outer side of the end plate 51 through a bearing, the connecting shaft 53 is fixedly arranged on the inner side of the end plate 51, and the square shaft 54 ​​is fixedly arranged on the connecting shaft 53. The top end is slidably arranged on the inner side of the square groove 43, the bottom plate 55 is fixedly arranged on the bottom end of the connecting shaft 53, the second guide rod 56 is fixedly arranged on the top edge of the bottom plate 55, the net tube 57 is slidably sleeved on the outer side of the second guide rod 56 along the vertical direction, the limiting shell 58 is fixedly arranged on the inner side of the net tube 57, the T-shaped rod 59 is slidably nested on the inner side of the limiting shell 58 along the vertical direction, the T-shaped rod 59 slides through the end plate 51 and its top end is fixedly connected to the movable ring.

[0026] By setting the above structure, during the upward movement of the lifting frame 44, the sweater carrying mechanism 5 rotates and rises inside the dyeing cylinder 21, and at the same time, the second annular magnet 52 drives the shielding sleeve 32 to rise synchronously through the first annular magnet 33. As the sweater carrying mechanism 5 continues to move upward, the sweater carrying mechanism 5 drives the dyed sweater out of the dye liquid. At this time, as the sweater carrying mechanism 5 continues to rotate, the dye liquid remaining in the sweater passes through the mesh cylinder 57 under the action of centrifugal force and is thrown out. At the same time, due to the obstruction of the shielding sleeve 32, the dye liquid falls into the inside of the dyeing cylinder 21 along the inner wall of the shielding sleeve 32 and is recovered.

[0027] like Figure 4 As shown, the blocking mechanism 6 includes an extension plate 61 and a blocking ring 62 , wherein two extension plates 61 are provided and are fixedly disposed on both sides of the inside of the housing 1 , respectively, and the blocking ring 62 is fixedly disposed between the two extension plates 61 and located on the top of the second annular magnet 52 .

[0028] By setting the above-mentioned sweater carrying mechanism 5 and blocking mechanism 6, after the top of the second annular magnet 52 is fitted with the bottom of the extension plate 61, due to the blocking of the extension plate 61, when the subsequent lifting frame 44 continues to move upward, the sliding sleeve 46, the end plate 51, the connecting shaft 53 and the bottom plate 55 cannot continue to move upward. As the lifting frame 44 continues to move upward, the connecting spring 45 is continuously stretched, and at the same time, the disc 47 drives the net tube 57 to move upward through the T-rod 59 and the limiting shell 58. After the net tube 57 moves upward, it detaches from the top of the bottom plate 55. At this time, the sweaters accumulated on the top of the bottom plate 55 are thrown to the top of the guide plate 36 under the action of centrifugal force, and then are discharged along the inclined surface at the top of the guide plate 36.

[0029] The present invention also discloses a method for using a wool sweater dyeing machine, which specifically comprises the following steps: S1. Add the wool sweater to be dyed into the net cylinder 57 through the top opening of the net cylinder 57, then start the forward and reverse motor 42, the forward and reverse motor 42 drives the screw 41 to rotate forward, the screw 41 drives the lifting frame 44 to descend when rotating, the lifting frame 44 drives the disc 47 to descend when descending, and at the same time drives the sliding sleeve 46 to descend through the connecting spring 45, and the sliding sleeve 46 drives the wool sweater carrying mechanism 5 to descend as a whole when descending; S2. As the sweater carrying mechanism 5 continues to descend, the sweater carrying mechanism 5 gradually drives the sweater into the dyeing drum 21, so that the sweater carrying mechanism 5 contacts the dyeing liquid and is dyed. In this process, the screw 41 drives the square shaft 54 ​​to rotate through the square groove 43. When the square shaft 54 ​​rotates, the sweater carrying mechanism 5 is driven to rotate as a whole, and the disc 47 is also driven to rotate by the sweater carrying mechanism 5. S3, the second annular magnet 52 is attached to the top of the first annular magnet 33 due to the continuous descent of the sweater carrying mechanism 5. At this time, due to the obstruction of the first annular magnet 33, the sweater carrying mechanism 5 cannot continue to move downward. Subsequently, as the lifting frame 44 continues to descend, the sliding sleeve 46 that cannot move downward compresses the connecting spring 45, and at the same time, the disc 47 drives the T-shaped rod 59 to descend inside the limit shell 58; S4, the forward and reverse motor 42 drives the screw 41 to rotate in the opposite direction, and the lifting frame 44 moves up and resets. During the upward movement of the lifting frame 44, the sweater carrying mechanism 5 rotates and rises inside the dyeing cylinder 21, and at the same time, the second annular magnet 52 drives the shielding sleeve 32 to rise synchronously through the first annular magnet 33; S5, the wool sweater carrying mechanism 5 drives the wool sweater to be removed from the dyeing liquid. At this time, as the wool sweater carrying mechanism 5 continues to rotate, the dyeing liquid remaining in the wool sweater passes through the net cylinder 57 under the action of centrifugal force and is thrown out. At the same time, due to the obstruction of the shielding sleeve 32, the dyeing liquid falls into the inside of the dyeing cylinder 21 along the inner wall of the shielding sleeve 32 and is recovered. S6. The second fixing ring 34 is fitted with the bottom of the guide plate 36 under the drive of the shielding sleeve 32. At this time, due to the obstruction of the guide plate 36, when the subsequent wool sweater carrying mechanism 5 continues to rise, the second annular magnet 52 is separated from the top of the first annular magnet 33, and then the shielding sleeve 32 is reset under the action of gravity; S7, after the lifting frame 44 arrives at the initial position, the top of the second annular magnet 52 fits with the bottom of the extension plate 61. Due to the obstruction of the extension plate 61, when the subsequent lifting frame 44 continues to move upward, the sliding sleeve 46, the end plate 51, the connecting shaft 53 and the bottom plate 55 cannot continue to move upward. As the lifting frame 44 continues to move upward, the connecting spring 45 is continuously stretched, and at the same time, the disc 47 drives the net cylinder 57 to move upward through the T-shaped rod 59 and the limit shell 58. After the net cylinder 57 moves upward, it is separated from the top of the bottom plate 55. At this time, the wool sweaters accumulated on the top of the bottom plate 55 are thrown to the top of the guide plate 36 under the action of centrifugal force, and then discharged along the inclined surface at the top of the guide plate 36; S8, the forward and reverse motor 42 is again driven to drive the screw rod 41 to rotate forward, and the lifting frame 44 moves downward to reset. After the lifting frame 44 reaches the initial position again, the forward and reverse motor 42 is stopped.

[0030] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
