[0028] The paper blowing machine according to the embodiments of the present application is described below with reference to the drawings.

[0029] Referring to Figures 1 to 6 , the paper blowing machine according to the embodiment of the present application comprises a paper barrel 1, a fan 2, a wind guide 3, and a driving mechanism 4. The paper barrel 1 is used for containing paper sheets, such as colored paper sheets. The fan 2 is used for generating an air flow towards the opening of the paper barrel 1, and the fan 2 can be a brushless fan. The wind guide 3 is arranged on the moving track of the air flow generated by the fan 2, and is used for changing the flow direction of the air flow. The driving mechanism 4 is connected with the wind guide 3, and is used for driving the wind guide 3 to swing. The paper blowing machine disturbs the air flow in the paper barrel 1 through the wind guide 3, and the disturbed air flow can make the stacked paper sheets loose, so that the paper sheets are more easily blown out uniformly.

[0030] The paper blowing machine can further comprise a supporting platform 5, and the fan 2, the wind guide 3, and the driving mechanism 4 are all mounted on the supporting platform 5. Specifically, the fan 2 can be fixed on the upper surface of the supporting platform 5 by means of bolts. The supporting platform 5 can be provided with two first bases 6 which are oppositely arranged, and the facing sides or the opposite sides of the two first bases 6 are both provided with shafts 7. Two connecting portions 8 of the wind guide 3 are formed with circular through holes 11 which are matched with the shafts 7, and the wind guide 3 swings under the driving of the driving mechanism 4. It should be understood that the wind guide 3 and the supporting platform 5 can also be connected in rotation by other structures. The supporting platform 5 can further be provided with a second base 9, and the driving mechanism 4 is fixedly connected with the second base 9.

[0031] The paper barrel 1 can be fixed below the supporting platform 5 by means of a hanger 10. The supporting platform 5 is formed with a through hole 11 which penetrates the upper surface and the lower surface of the supporting platform 5, and the air flow generated by the fan 2 passes through the through hole 11 from top to bottom. Specifically, the fan 2 can be fixed on the upper surface of the supporting platform 5 by means of bolts. The wind guide plate 12 of the wind guide 3 is located below the supporting platform 5, and the wind guide plate 12 of the wind guide 3 passes below the through hole 11 in the process of swinging. Of course, the supporting platform 5 is also formed with a hole through which the two connecting portions 8 of the wind guide 3 pass, and the size of the hole needs to meet the requirement that the wind guide 3 has enough swinging space.

[0032] In the embodiment, when the wind guide plate 12 is in the first swinging area, one side surface of the wind guide plate 12 can act on the air flow generated by the fan 2; correspondingly Figure 3 from the perspective, when the wind guide plate 12 is in the A area, the right side surface of the wind guide plate 12 can act on the air flow generated by the fan 2. When the wind guide plate 12 is in the second swinging area, the other opposite side surface of the wind guide plate 12 can act on the air flow generated by the fan 2; correspondingly Figure 3When the angle of view is in the B region, the left surface of the air deflector 12 can act on the air flow generated by the fan 2. Thus, the air deflector 12 can change the flow direction of the air flow, and the air flow can flow in a wider range, no matter whether the air deflector 12 is in the first swing region or the second swing region. In an embodiment, the air deflector 12 can only swing in the first swing region and the second swing region; in another embodiment, the air deflector 12 can swing in the first swing region and the second swing region, and can also swing to the outside of the first swing region or the second swing region.

[0033] Now referring to Figure 7 The air deflector 12 can specifically include a first air deflector part 13, and a second air deflector part 14 formed by extending the front end edge of the first air deflector part 13 obliquely forward.

[0034] The connecting part 8 of the air deflector 3 is also formed with a long-hole 15. The driving mechanism 4 includes a motor 16 and a crank 17 sleeved on the output end of the rotating shaft of the motor 16. The crank 17 is formed with a column extending into the long-hole 15, and a roller is sleeved on the column. The crank 17 and the connecting part 8 form a crank 17 rocker mechanism, so that when the motor 16 works, the air deflector 3 can be swung. It should be understood that the driving mechanism 4 can also adopt other suitable structures, and the air deflector 3 can also form other structures cooperating with the driving mechanism 4 to realize that the driving mechanism 4 can drive the air deflector 3 to swing.

[0035] Now returning to Figures 1 to 6 The paper barrel 1 is generally in the shape of an inverted circular truncated cone, and the opening is upward. The virtual axis of the through hole 11 of the supporting platform 5 coincides with the virtual axis of the bottom of the paper barrel 1, that is, when the air flow generated by the fan 2 is not affected by the air deflector 3, it can directly and vertically reach the center of the bottom of the paper barrel 1, and under the action of the air deflector 3, the air flow can directly reach more areas of the bottom of the paper barrel 1. The disturbed air flow can make the accumulated paper sheets become loose, so that the paper sheets are more easily and uniformly blown out.

[0036] In the embodiment, the outer periphery of the supporting platform 5 projects to the plane where the opening of the paper barrel 1 is located, and surrounds the opening of the paper barrel 1, so as to reduce or even avoid the paper sheets blown out of the paper barrel 1 from falling on the supporting platform 5.

[0037] The paper blowing machine can further comprise a machine box 18 fixedly connected with the supporting platform 5, such as by screwing. The machine box 18 and the supporting platform 5 jointly enclose a space surrounding the fan 2 and the driving mechanism 4, and the machine box 18 is formed with an air inlet hole. The machine box 18 can prevent sundries, paper sheets and the like from entering the space to interfere with the working of the components such as the driving mechanism 4 and the fan 2. The machine box 18 can be provided with a hanger 19 for hoisting the paper blowing machine in the air. Of course, the machine box 18 can also be provided with a safety lifting ring 20 tied with a safety rope to prevent the paper blowing machine from falling in case of damage of the hanger 19.

[0038] The paper blowing machine can further comprise a control circuit 21 and a power supply 22, both of which are arranged in the machine box 18. The control circuit 21 is electrically connected with the driving mechanism 4 and the fan 2. The control circuit 21 can control the start and stop of the motor 16 and the rotating speed of the motor 16, and the rotating speed of the motor 16 can be controlled to adjust the swinging frequency of the air guide member 3. The control circuit 21 can also control the start and stop of the fan 2 and the rotating speed of the fan 2, and the rotating speed of the fan 2 can be controlled to adjust the flow rate of the airflow generated by the fan 2. The power supply 22 provides electric energy for the electric components of the paper blowing machine, such as the control circuit 21, the driving mechanism 4, the fan 2 and the like.

[0039] The paper blowing machine of the embodiment can disturb the airflow in the paper barrel 1 through the air guide member 3, and the disturbed airflow can make the stacked paper sheets loose, so that the paper sheets can be more easily and uniformly blown out.
