The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] A powder feeding device for a mixing device, such as Figure 1 , Figure 2 As shown, it includes a powder screening component, a driving component, and a filtering and recycling component. The powder screening component includes a powder screener 7, a scraper 8, a powder sweeper 9, and a vibration motor 10. The lower half of the powder screener 7 is in a stepped structure. A groove is provided on the higher side of the bottom. Several springs are provided in the groove. One end of the spring is connected to the powder screener 7. The vibration motor 10 is installed on the other side of the spring. A plastic plate is connected to the output end of the vibration motor 10. The size of the plastic plate is adapted to the size of the groove. The feeding device also includes a control module. The vibration motor 10 is electrically connected to the control module. A powder sweeper 9 is provided on the lower plane at the bottom of the powder screener 7. The powder sweeper 9 is adhered to the powder screener 7 and has a coarse upper and fine lower structure with the powder sweeper 9. The finer side contacts the feeding device and is made of rubber. The side connected to the powder screener 7 is coarser and is made of plastic. The scraper 8 is adhered to the powder screener 7. Slopes are provided on both sides of the scraper 8, and the slope of the side facing the powder sweeper 9 is larger.

[0026] The vibration motor 10 in the powder screening component can make the powder on the feeding device quickly enter the device. When the powder screening component is working, the powder can be swept by the powder sweeper 9, and the scraper 8 can smooth the powder on the feeding device to facilitate the next step of filtering.

[0027] like Figure 1 As shown, the driving assembly includes a bracket 2, a DC motor 3, a connecting rod 4, an electric push rod 5, and a DC motor 6. The DC motor 3 is installed on the connecting rod 4 by bolts, and the DC motor 3 is electrically connected to the control module. The connecting rod 4 is connected to the output end of the DC motor 3. A hole is provided on one side of the connecting rod 4, and the output end of the electric push rod 5 is installed on the connecting rod 4 through the hole. The electric push rod 5 is electrically connected to the control module, and the DC motor 6 is connected to the output end of the electric push rod 5. The output end of the DC motor 6 is connected to the powder screening assembly.

[0028] The powder screening component can be moved by the driving component, so that the powder screening component rotates in the feeding device to accelerate the powder entering the device. At the same time, the movement range of the driving component and the powder screening component is small, which will not cause powder overflow.

[0029] like Figure 1 , Figure 3As shown, the feeding device also includes a shell 11, a shell 2 15, and a storage box 1. The storage box 1 is connected to a bracket 2. A groove is provided inside the storage box. A circular hole is provided on the top of the storage box 1. The shell 2 15 is welded to the storage box 1. The structure of the shell 2 15 is divided into two parts. The lower half is an annular structure. The annular structure of the shell 2 is adapted to the size of the circular hole of the storage box 1. The upper half is an inverted isosceles trapezoidal structure with a certain slope inside. A hole groove is provided on one side of the upper half. The shell 11 is an annular structure welded to the shell 2 15.

[0030] like Figure 4 As shown, the filtering and recovery component includes a mesh screen 12 and a spring 13. There are several springs 13, which are evenly distributed around the inner wall of the shell 11. One side of the spring 13 is connected to the shell 11. A stainless steel ring structure is arranged on the outer side of the mesh screen 12, and a mesh surface is arranged on the inner side. A small clamp is arranged on the outer side of the mesh screen 12, and the other side of the spring 13 is connected to the clamp. There is a gap between the mesh screen 12 and the shell 11. A section of arc-shaped elastic fabric is arranged on the spring 13, and the elastic fabric connects the stainless steel ring structure on the mesh screen 12 and the inner wall of the shell 11.

[0031] In this case, the vibration motor 10 on the powder screening assembly vibrates the mesh screen 12, vibrating the powder on the mesh screen 12 into the storage box 1. At the same time, the spring 13 can fix the mesh screen 12 to reduce the overall vibration amplitude when the feeding device is working, thereby avoiding damage to other parts.

[0032] like Figure 1 , Figure 4 As shown, the filter recovery assembly also includes a filter storage box 14, which is located between the shell 11 and the shell 15, and is installed on the hole groove of the shell 15. The interior of the filter storage box 14 has a certain slope, and a groove is provided on the upper part. The size of the groove is smaller than the gap between the mesh 12 and the shell 11. The bottom of the outer side of the filter storage box 14 has an arc, and the filter storage box 14 can be removed from the shell 15.

[0033] During the process of adding powder, there may be impurities and powder that has condensed into lumps. The impurities can be swept into the gap between the mesh screen 12 and the outer shell 11 through the powder screening device, and the impurities enter the filter storage box 14. After the adding is completed, the filter storage box 14 can be removed, the impurities can be poured out and re-screened, and the condensed powder can be ground into powder and re-added to avoid waste.

[0034] like Figure 3As shown, the feeding device also includes a bracket 2 16, a DC motor 3 17, and a screw rod 18. There are two DC motors 3 17 installed in the housing 2 15. The bracket 2 16 is welded on both sides of the DC motor 3 17. A conical cover plate is provided on the DC motor 3 17. The two DC motors 3 17 are connected to the cover plate. The screw rod 18 is connected to the output shaft of the DC motor 3 17 through a coupling.

[0035] The two screw rods 18 can better deliver the powder into the storage box 1 to avoid transportation blockage and affect production efficiency.

[0036] Working principle: the operator pours the powder onto the mesh sieve 12, and the control module controls the powder screening component to work through the drive component according to the preset program to filter the powder on the mesh sieve 12. After the qualified powder is transferred to the storage box 1 through the screw rod 18, the powder screening component is controlled by the control module to clean the impurities on the mesh sieve 12 and sweep the impurities into the filter storage box 14. Then the control module stops the operation of the drive component, and the operator removes the filter storage box 14, filters the impurities again and then installs the filter storage box 14 back on the outer shell 15, waiting for the next process to start.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
