[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A carding device for an air spinning device, including a carding roller assembly 1, a feeding hopper 2 is installed above the carding roller assembly 1, fiber discharging assemblies 4 are installed on both sides of the carding roller assembly 1, a spinning cup 5 is installed on the side of the fiber discharging assembly 4 away from the carding roller assembly 1, an impurity outlet 7 is opened at the bottom of the carding roller assembly 1, a vertical plate 8 is installed at the bottom of the carding roller assembly 1 and at a position on one side of the impurity outlet 7, a storage and drying device 3 is installed outside the feeding hopper 2, and an impurity collecting device 6 is installed on one side of the vertical plate 8 and at a position below the impurity outlet 7.

[0023] Specifically, the storage and drying device 3 includes a mesh rack 31, a storage bin 32, a drying assembly 33 and an electric telescopic rod 34. A mesh rack 31 is installed outside the feeding hopper 2, a storage bin 32 is arranged inside the mesh rack 31 and at a position diagonally above the feeding hopper 2, the mesh rack 31 and the storage bin 32 are connected by an electric telescopic rod 34, and a drying assembly 33 is installed on the top of the mesh rack 31.

[0024] By adopting the above technical solutions, it enables the staff to store the unprocessed cotton fiber through the cooperation of structures such as the storage bin 32 and the electric telescopic rod 34 when needed, thus better meeting the working needs in different situations.

[0025] Specifically, the drying assembly 33 includes an electric heating rod 331, a fan 333, and a connecting cylinder 334. The connecting cylinder 334 is installed at the top of the mesh rack 31. The fan 333 is installed inside the connecting cylinder 334. A plurality of electric heating rods 331 are installed inside the connecting cylinder 334 at a position below the fan 333.

[0026] By adopting the above technical solution, it enables the staff to perform a certain drying treatment on the unprocessed cotton strip fibers through the cooperation of structures such as the electric heating rod 331 and the fan 333 when needed, thus better meeting the working needs in different situations.

[0027] Specifically, the drying assembly 33 further includes a partition net 332. The partition net 332 is installed above the connecting cylinder 334.

[0028] By adopting the above technical solution, the device can prevent external impurities from entering the connecting cylinder 334 through the partition net 332, thereby reducing the possibility of adverse effects on structures such as the fan 333 and the electric heating rod 331, and better meeting the working needs.

[0029] When this embodiment is in use, when the rotor spinning equipment needs to use the device for carding work, the staff can store the cotton strip fibers in the storage bin 32 of the storage and drying device 3 in advance. And when the cotton strip fibers are damp, the staff can start the fan 333 and each electric heating rod 331 in the drying assembly 33. Under the action of the fan 333, air passes through the partition net 332 and enters the connecting cylinder 334. Each electric heating rod 331 heats the air, and then the hot air contacts the cotton strip fibers, thereby drying the cotton strip fibers. The used air with moisture passes through the mesh rack 31 and is discharged. During work, the staff starts the electric telescopic rod 34 to drive the storage bin 32 to move above the feed hopper 2, and then the cotton strip fibers pass through the feed hopper 2 and enter the carding roller assembly 1. The carding roller assembly 1 is manipulated to tear and throw out the cotton strip fibers. The fiber discharging assembly 4 cooperates with the spinning cup 5 to process the fibers, and the impurities pass through the impurity outlet 7 and are discharged, thereby performing carding work.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the impurity receiving device 6 includes a fixed box 61, a lifting plate 62, a lead screw 63, a lifting box 64, and a rotating plate 65. The fixed box 61 is installed on one side of the vertical plate 8 at a position below the impurity outlet 7 through screws. The lead screw 63 is installed at the edge position of the fixed box 61 through a bearing. The rotating plate 65 is installed above the lead screw 63. The lifting plate 62 is installed on the outer side of the lead screw 63 at a position inside the fixed box 61 through threads. The lifting box 64 is installed on one side of the lifting plate 62.

[0032] By adopting the above technical solution, the staff can adjust the capacity of impurities through the cooperation adjustment device of structures such as the fixed box 61 and the lifting box 64 when needed, thus better meeting the working needs in different situations.

[0033] Specifically, the inner width of the fixed box 61 is equal to the outer width of the lifting plate 62.

[0034] By adopting the above technical solution, the device can ensure that the inner side of the fixed box 61 is tightly attached to the outer side of the lifting plate 62, thereby preventing the lifting plate 62 from rotating and shifting during movement, and further ensuring the normal progress of the work.

[0035] When this embodiment is in use, when needed, the staff can connect the fixed box 61 in the impurity picking device 6 to the vertical plate 8 through screws, and then rotate the rotating plate 65, thereby driving the screw rod 63 to rotate. The screw rod 63 is threadedly connected to the lifting plate 62, and the outer side of the lifting plate 62 is tightly attached to the inner side of the fixed box 61. Therefore, the screw rod 63 drives the lifting plate 62 and the lifting box 64 thereon to move, thereby adjusting the capacity of the fixed box 61 and the lifting box 64. Then, the impurities discharged from the impurity outlet 7 can be picked up through the fixed box 61 and the lifting box 64.

[0036] In the present utility model, the structure and principle of the carding roller assembly 1 composed of the carding roller housing, the driving rotating shaft, the driven rotating shaft, the driving carding roller, the driven carding roller and the protrusions, the fiber discharging assembly 4 composed of the fiber discharging port and the baffle, the spinning cup 5, and the impurity outlet 7 have been disclosed in a carding device of an air jet spinning machine with the Chinese patent application number 201921879869.2. Its working principle is that when the rotating motor works, it drives the driving rotating shaft to rotate. The driving rotating shaft drives the driven rotating shaft to rotate through gears, so that the driving carding roller and the driven carding roller start to rotate and their rotation directions are opposite. At this time, the rotation directions of the adjacent parts between the driving carding roller and the driven carding roller are both downward, so as to realize the tearing and throwing out of the cotton strip fibers; a impurity collection box for collecting impurities is also provided at the bottom of the impurity outlet. Such a setting can collect impurities and prevent impurities from affecting subsequent work.

[0037] Working principle and usage process of the present utility model: When the air-jet spinning equipment needs to use the device for carding work, the staff can store the sliver fibers in the storage bin 32 of the storage and drying device 3 in advance. And when the sliver fibers get damp, the staff can start the fan 333 and each electric heating rod 331 in the drying component 33. Under the action of the fan 333, air passes through the partition net 332 and enters the connecting cylinder 334. Each electric heating rod 331 heats the air. Then the hot air contacts the sliver fibers, thereby drying the sliver fibers. The used air with moisture passes through the mesh rack 31 and is discharged. During work, the staff starts the electric telescopic rod 34 to drive the storage bin 32 to move above the feed hopper 2. Then the sliver fibers pass through the feed hopper 2 and enter the carding roller assembly 1. The staff manipulates the carding roller assembly 1 to tear and throw out the sliver fibers. The fiber discharging assembly 4 cooperates with the spinning cup 5 to process the fibers, while the impurities pass through the impurity outlet 7 and are discharged, thus performing carding work; When needed, the staff can connect the fixed box 61 in the impurity collecting device 6 to the vertical plate 8 through screws, and then rotate the rotating plate 65, thereby driving the screw rod 63 to rotate. The screw rod 63 is threadedly connected to the lifting plate 62, and the outer side of the lifting plate 62 is closely attached to the inner side of the fixed box 61. Therefore, the screw rod 63 drives the lifting plate 62 and the lifting box 64 thereon to move, thereby adjusting the capacity of the fixed box 61 and the lifting box 64. Then the impurities discharged from the impurity outlet 7 can be collected through the fixed box 61 and the lifting box 64.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
