DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] See also Figures 1 to 5 The present embodiment provides an impeller device, comprising: a central hub 10; a plurality of blades 20, which are mounted around the central hub 10; a plurality of cutter heads 30, which are mounted correspondingly to the blades 20, and the cutter heads 30 extend on the blades 20 in the direction of the rotation axis of the impeller device; wherein, when the blades 20 drive the cutter heads 30 to rotate, the cutter heads 30 can quickly cut off the paper tape on the blades 20.

[0036] Specifically, in this embodiment, eight blades 20 are mounted on the central hub 10, and a cutter head 30 is mounted on each of the eight blades 20. The cutter head 30 is mounted on the blade 20 near the central hub 10. The cutter head 30 extends on the blade 20 in the direction of the rotation axis of the impeller device. When the impeller device rotates, the airflow direction generated by the impeller device is in the same direction as the rotation axis direction of the impeller device. Therefore, when the paper tape brought by the airflow reaches the central hub 10, it will be cut by the rotating cutter head 30.

[0037] Furthermore, the blade 20 includes a central portion 21 and an edge portion 22 , the central portion 21 is connected to the central hub 10 , and the blade 20 is bent at the connection between the central portion 21 and the edge portion 22 .

[0038] Specifically, the blade 20 is bent from the middle, and after the bending, the blade 20 close to the central hub 10 is the central portion 21, and the blade 20 away from the central hub 10 is the edge portion 22. The bent blade 20 can increase the rigidity and stability of the blade 20, and can also reduce the vibration and noise of the blade 20, and reduce the energy loss of the blade 20. Among them, the bending direction of the eight blades 20 in this embodiment is consistent, and the bending direction of the blade 20 is opposite to the rotation direction of the impeller device.

[0039] Furthermore, the impeller device further includes a cover plate 40 , which is disposed between adjacent blades 20 .

[0040] Specifically, a cover plate 40 is disposed between adjacent blades 20 , and the bottom of the cover plate 40 is fixed to the central hub 10 , and both sides of the cover plate 40 are fixed to the blades 20 respectively.

[0041] Further, when the cover plate 40 is connected to the central hub 10 and the blade 20 , the cover plate 40 extends from the connection between the central hub 10 and the blade 20 to the edge of the blade 20 .

[0042] Specifically, when the cover plate 40 is fixed to the central hub 10 and the blades 20, the bottom of the cover plate 40 extends from the central hub 10 to the edge of the blade 20, forming a certain angle between the cover plate 40 and the rotation axis of the impeller device. This can guide the airflow to a certain extent, making the airflow flow more uniformly inside the impeller device. Moreover, it can also increase the rigidity of the blade 20 and extend the service life of the blade 20.

[0043] Further, the impeller device further includes a rib plate 50, and the rib plate 50 is installed at the edge portion 22.

[0044] Specifically, the rib plate 50 is radially installed at the edge portion 22 of the blade 20, and the cover plate 40 is installed at the central portion 21 of the blade 20. The rib plate 50 cooperates with the cover plate 40 to effectively prevent the winding of the paper tape. Among them, the cover plate 40 can effectively prevent the paper tape from winding around the central hub 10, while the rib plate 50 can effectively prevent the paper tape from winding around the blade 20.

[0045] Further, the impeller device further includes an impeller back plate 60. The impeller back plate 60 is installed on the central hub 10, and the rib plate 50 is connected and fixed to the impeller back plate 60.

[0046] Specifically, the impeller back plate 60 is installed on one side of the central hub 10 close to the rib plate 50. Among them, the top of the cover plate 40 contacts the impeller back plate 60, and moreover, the rib plate 50 is also fixed to the impeller back plate 60. The installation of the impeller back plate 60 can improve the airflow between the impellers, reduce the vortex loss of the airflow, and improve the working efficiency of the impeller device.

[0047] Further, the cutter head 30 is installed at the central portion 21, and the cutter head 30 extends from the bending portion of the blade 20 in the direction of the rotation axis of the impeller device.

[0048] Specifically, the cutter head 30 starts from the bending portion of the blade 20 and extends in the direction of the rotation axis of the impeller device, so that the rotation range of the central portion 21 of the blade 20 forms a cutting range. As long as the paper tape enters the rotation range of the central portion 21, it will be cut by the cutter head 30.

[0049] Further, the cutter head 30 includes a first side surface 31, a second side surface 32, and a third side surface 33; among them, the second side surface 32 contacts the blade 20, and the first side surface 31 is on the side of the cutter head 30 away from the blade 20; there is an angle between the second side surface 32 and the first side surface 31, and the closer to the third side surface 33 on the first side surface 31, the farther away from the second side surface 32; moreover, a cutting edge 34 is formed between the first side surface 31 and the third side surface 33. When the impeller device rotates, the cutting edge 34 can cut off the paper tape.

[0050] Specifically, when the cutter head 30 is installed on the blade 20, the second side surface 32 contacts the blade 20, and the first side surface 31 is the opposite side of the second side surface 32 on the cutter head 30. An included angle is formed between the first side surface 31 and the second side surface 32, such that the distances at various positions between the first side surface 31 and the second side surface 32 are different. The closer to the third side surface 33 on the first side surface 31, the farther the distance from the second side surface 32. Thus, a cutting edge 34 is formed between the first side surface 31 and the third side surface 33. After the impeller device rotates to a certain speed, the cutting edge 34 can cut the paper tape.

[0051] Specifically, the cutter head 30 is made of hard alloy steel, and the hard alloy steel forming the cutting edge 34 can quickly cut the paper tape. Moreover, the cutter head 30 is welded to the blade 20, with a simpler structure and lower cost.

[0053] Specifically, the connecting body 11 is used to connect and fix the blade 20, the cover plate 40, and the impeller back plate 60. The through hole 12 is provided at the center of the connecting body 11, and the groove 13 communicates with the through hole 12. The impeller device can be installed and fixed through the groove 13 and the through hole 12.

[0055] Specifically, when the motor 72 penetrates through the housing 71 and is connected to the central hub 10, the impeller back plate 60 corresponds to the motor 72, and the cutter head 30 and the cover plate 40 correspond to the air inlet 73. Among them, the central hub 10, the blade 20, the cutter head 30, the cover plate 40, the rib plate 50, and the impeller back plate 60 are all arranged inside the housing 71.
