[0027] Please refer to Figures 1 to 7 As shown, an electrospinning device for preparing nano-micron fiber materials provided by the utility model is now described. The electrospinning device for preparing nano-micron fiber materials includes a receiving device, which includes a bracket 1, a receiving unit 2, a rotating shaft 3, a bearing cylinder 1 4 and a bearing cylinder 2 5. The bearing cylinder 1 4 and the bearing cylinder 2 5 are arranged on the bracket 1 at intervals, and a ball head 31 is provided at the first end of the rotating shaft 3. An elastic member 42 is installed between the ball head 31 and the bearing cylinder 1 4. The elastic member 42 is used to apply elastic force The ball head 31 and the rotating shaft 3 are moved along the first direction until the second end of the rotating shaft 3 has a tendency to be inserted into the bearing tube 2 5, and the ball head 31 has a tendency to abut against the bearing tube 1 4. In this way, under the elastic force of the elastic member 1 42, the ball head 31 abuts against the bearing tube 1 4, and the second end of the rotating shaft 3 is inserted into the bearing tube 2 5 and abuts against the bearing tube 2 5, so that the rotating shaft 3 is connected to the bracket 1, and the receiving unit 2 is detachably sleeved on the rotating shaft 3, so that the receiving unit 2 can be connected to the bracket 1 along with the rotating shaft 3. Figure 6 As shown, in addition, when the rotating shaft 3 is moved in a second direction opposite to the first direction, the elastic force of the elastic member 42 can be resisted to drive the second end of the rotating shaft 3 to escape from the bearing tube 5, as shown in FIG. Figure 7 As shown, when the second end of the rotating shaft 3 is disengaged from the supporting tube 2 5, the rotating shaft 3 can rotate around the center of the ball head 31 until the second end of the rotating shaft 3 swings to the point where the receiving unit 2 sleeved on the rotating shaft 3 can be disengaged from the second end of the rotating shaft 3, so as to replace the receiving unit 2 of different styles. For example, the receiving unit 2 has a drum type and a plate type. The receiving unit 2 of the corresponding required style is replaced on the rotating shaft 3, and then reinserted into the supporting tube 2 5 from the second end of the rotating shaft 3. The operation is convenient and quick. Therefore, the receiving device provided in the embodiment of the utility model and the electrospinning equipment for preparing nano-micron fiber materials having the receiving device can conveniently change the style of the receiving device to adapt to different work requirements.

[0028] like Figure 2 As shown, in some of the embodiments, the receiving unit 2 is provided with a through hole 21 adapted to the rotating shaft 3 , and the rotating shaft 3 can be inserted into and fixed in the through hole 24 of the receiving unit 2 .

[0029] like Figure 5 As shown, in some embodiments, a limiting hole 41 is provided in the inner cavity of the bearing tube 1 4, and the limiting hole 41 has a size smaller than the large circle of the ball head 31, so that when the ball head 31 passes through the limiting hole 41 from the bearing tube 1 4 to the bearing tube 2 5, the side of the ball head 31 facing the bearing tube 2 5 will eventually abut against the limiting hole 41, so that the ball head 31 and the limiting hole 41 abut to form a contact line 9 to limit the ball head 31 from continuing to move from the bearing tube 1 4 to the bearing tube 2 5. The elastic member 1 42 is located on the side of the ball head 31 facing away from the bearing tube 2 5, and the elastic member 1 42 is compressed and abutted between the bearing tube 1 4 and the ball head 31, so that the elastic member 1 42 can apply an elastic abutting force to the ball head 31, so that the ball head 31 can move along the first direction until the ball head 31 abuts against the limiting hole 41 on the bearing tube 1 4, and at the same time, the rotating shaft 3 The second end of the rotating shaft 3 is inserted into the supporting tube 25 and abuts against the supporting tube 25, so that under the action of the elastic force of the elastic member 42, the ball head 31 of the first end of the rotating shaft 3 is kept in abutment with the supporting tube 4, and the second end of the rotating shaft 3 is inserted into the supporting tube 25 and abuts against the supporting tube 25. In addition, when it is necessary to detach the second end of the rotating shaft 3 from the inner cavity of the supporting tube 25, the rotating shaft 3 can be moved in a second direction opposite to the first direction to resist the elastic force of the elastic member 42 and compress the elastic member 42, so that the second end of the rotating shaft 3 is finally detached from the inner cavity of the supporting tube 25. When the second end of the rotating shaft 3 is detached from the supporting tube 25, the second end of the rotating shaft 3 can rotate around the center of the ball head 31 until the second end of the rotating shaft 3 swings until the receiving unit 2 sleeved on the rotating shaft 3 can be detached from the second end of the rotating shaft 3, so as to replace the receiving unit 2.

[0030] like Figure 5 As shown, in some embodiments, the limiting hole 41 is a trumpet hole with a circular cross section, and the aperture of the limiting hole 41 gradually decreases from the bearing tube 1 4 to the bearing tube 2 5, so that when the ball head 31 moves from the limiting hole 41 in the direction of the bearing tube 2 5, the large circle of the ball head 31 and the side facing the bearing tube 2 5 will contact with the side wall of the limiting hole 41, so that a circular contact line 9 is formed between the ball head 31 and the limiting hole 41. It can be understood that in some other embodiments, the limiting hole 41 can also be a trumpet hole with a triangular, square or hexagonal cross section.

[0031] like Figure 4As shown, in some embodiments, a driver 11 is also installed on the bracket 1. The driver 11 is a driving device that outputs circular motion power. The output end of the driver 11 is connected to the bearing cylinder 2 5 by transmission. Specifically, the output end of the driver 11 is connected to the bearing cylinder 2 5 by a gear structure. It can be understood that the output end of the driver 11 and the bearing cylinder 2 5 can also be connected by belt transmission, chain transmission, etc. In this embodiment, the driver 11 is a motor. In other embodiments not shown in the figure, the output end of the driver 11 can also be connected to the bearing cylinder 1 4 by transmission.

[0032] like Figure 5 As shown, in some embodiments, the bearing tube 1 4 is a cylindrical structure with two ends open, and a locking plate 44 is provided on the opening of the end of the bearing tube 1 4 facing away from the bearing tube 2 5, and a positioning block 43 is installed on the locking plate 44, and one end of the elastic member 1 42 is connected to the positioning block 43, and the other end of the elastic member 1 42 is against or connected to the ball head 31. In this way, when the rotating shaft 3 needs to be removed, the ball head 31 and the rotating shaft 3 can be taken out from the opening of the end of the bearing tube 1 4 facing away from the bearing tube 2 5 by opening the locking plate 44, and the disassembly and assembly between the receiving unit 2 and the rotating shaft 3 can be completed. In this way, when the receiving unit 2 is large in size, the rotating shaft 3 is prevented from being blocked by the receiving unit 2 when swinging around the ball head 31. At this time, the ball head 31 and the rotating shaft 3 can be taken out from the opening of the end of the bearing tube 1 4 facing away from the bearing tube 2 5. In this embodiment, the elastic member 1 42 is a coil spring.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
