[0031] Combine Figures 1 to 5 As shown, an automatic vacuum feeder provided by the present invention in a novel manner includes a box body 1, a vacuum pump 2, a rotating shaft 3 and a motor 4.

[0032] Combine Figures 1 to 5As shown, the box body 1 is designed with a storage space 13, a discharge space 14, a feed port 15 and a discharge port 16. The storage space 13 is located above the discharge space 14, the feed port 15 is connected to the storage space 13, and the discharge port 16 is connected to the discharge space 14. The box body 1 is equipped with a pressure valve 19, and the pressure valve 19 is connected to the discharge port 16; the vacuum pump 2 is connected to the box body 1, and the vacuum pump 2 acts on the storage space 13; the rotating shaft 3 is located in the discharge space 14 inside the box body 1, and the length of the rotating shaft 3 is less than that of the discharge space 14. length, a spiral blade 31 is designed on the rotating shaft 3; the motor 4 is connected to the rotating shaft 3, and a low-pressure environment is generated in the storage space 13 through the vacuum pump 2 to complete the material taking action, and the rotating shaft 3 is driven to move by the motor 4. The rotating shaft 3 rotates in the discharging space 14, and the material in the storage space 13 is continuously sent into the discharging space 14, completing the pressurization of the discharging space 14. When the pressure in the discharging space 14 is sufficient, the pressure valve 19 will be pushed open to complete the discharging action, thereby achieving high-efficiency and stable feeding work. The feeding efficiency can be adjusted by adjusting the motor.

[0033] In some embodiments, combined Figure 4 As shown, the connection between the bottom of the storage space 13 and the discharge space 14 of the box body 1 is funnel-shaped, which can effectively reduce the residual material in the storage space 13, and at the same time is conducive to the material entering the discharge space 14, which can improve the working stability of the feeder.

[0034] In some embodiments, combined Figure 4 、 Figure 5 As shown, the box body 1 includes a shell 11 and an upper cover 12, the feed port 15 is located on the upper cover 12, and the discharge port 16 is located on the shell 11, which can facilitate the inspection of the internal situation of the feeder and facilitate subsequent maintenance, thereby indirectly improving the stability of the feeder.

[0035] In some embodiments, combined Figure 2 、 Figure 5 As shown, the box body 1 also includes a sealing ring 17. A sealing groove is opened on the shell 11. The sealing ring 17 is installed in the sealing groove, which can effectively improve the sealing of the box body, improve the working effect of the vacuum pump 2, and improve the working efficiency of material removal.

[0036] In some embodiments, combined Figure 4 、 Figure 5 As shown, the feed port 15 opened on the upper cover 12 is away from the side connected to the vacuum pump 2, which can reduce the possibility of the material entering the storage space 13 and being sucked into the vacuum pump 2, thereby improving the working stability of the vacuum pump 2.

[0037] In some embodiments, combined Figure 4、 Figure 5 As shown, the box body 1 also includes a grille 18, which is installed inside the storage space 13 of the box body 1. The grille 18 is close to the connection between the box body 1 and the vacuum pump 2, which can avoid the phenomenon of blocking the vacuum pump after the material accumulates in the storage space 13, thereby improving the working stability of the feeder.

[0038] In some embodiments, combined Figure 1 、 Figure 2 As shown, the feeder further comprises a support frame 5, on which a box body 1, a vacuum pump 2 and a motor 4 are fixed, so that the connection between the feeder components is tighter, the structural strength of the feeder is improved, and the movement of the feeder is facilitated.

[0039] In some embodiments, combined Figures 1 to 3 As shown, the feeder also includes a one-way valve 6, which is installed between the discharge port 16 and the pressure valve 19. The inlet end of the one-way valve 6 is connected to the discharge port 16 of the box body 1, which can prevent the air from reversely entering the discharge space 14 from the discharge port 16 due to the absence of material in the discharge space when the work starts, thereby avoiding possible startup problems and improving the working stability of the feeder.

[0040] In some embodiments, combined Figure 2 、 Figure 5 As shown, the rotating shaft 3 also includes a fastener 32, which is sleeved on the rotating shaft 3 and fixed to the box body, so that the axial force applied to the rotating shaft 3 during operation will not be transmitted to the motor 4, thereby improving the working stability of the motor 4.

[0041] In some embodiments, combined Figures 1 to 3 As shown, the motor 4 moves in one direction, with the motor 4 driving the rotating shaft 3 to complete the discharging action as the positive direction. When the motor 4 moves in the reverse direction, the material cannot be discharged from the discharging space 14, which will cause damage to the feeder. The unidirectional movement of the motor 4 can avoid the occurrence of damage to the feeder caused by the reversal of the motor 4 due to various reasons.

[0042] Working process: the vacuum pump 2 is working, and the vacuum pump 2 is connected to the box body 1. The vacuum pump 1 acts on the storage space 13, so that the storage space 13 becomes a low-pressure environment, and the pressure difference is used to suck the material to complete the material removal action; after the material enters the storage space 13 along the feed port 15, it falls downward under the action of its own gravity and accumulates at the bottom of the storage space 13. Since the connection between the storage space 13 and the discharge space 14 is funnel-shaped, the material will continue to approach the rotating shaft 3 along this point. At this time, the motor 4 will drive the rotating shaft 3 to rotate in the discharge space 14, and continuously send the material in the storage space 13 into the discharge space 14, completing the pressurization of the discharge space 14. When the pressure in the discharge space 14 is sufficient, the pressure valve 19 will be opened to complete the discharge action; by adjusting the motor 4 to change the speed of the rotating shaft 3, the feeding efficiency of the feeder can be adjusted.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
