[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model is described in detail with reference to the schematic diagrams.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a photovoltaic powder packaging machine, including:

[0035] Please see Figures 1-5 This utility model provides a technical solution:

[0036] A photovoltaic powder dispensing machine includes a base 1. A powder hopper 3 is bolted to one side of the base 1. A vertical groove 18 is formed at the bottom of the powder hopper 3. A vertical plate 15 is provided below the vertical groove 18. An internal thread 20 is formed on the inner wall of the vertical plate 15. An external thread 19 is formed on the inner wall of the vertical groove 18. The internal thread 20 is threaded to the inner wall of the external thread 19. A connecting block 16 is bolted to the bottom of the vertical plate 15. An elastic tube 17 is provided at the bottom of the connecting block 16. The vertical plate 15, which is threaded to the internal thread 20 and the external thread 19, allows the elastic tube 17 to be properly installed at the bottom of the powder hopper 3. This facilitates better adjustment of the discharge height and reduces powder splashing.

[0037] It is worth noting that, in order to better adjust the flow rate of the falling powder, specifically, a retaining ring 12 is fitted onto the outer circumference of the powder hopper 3, and a retaining pin 13 is inserted and fixed into the inner wall of the retaining ring 12. A handle 14 is bolted to one side of the retaining pin 13. An inner cavity 8 is formed in the inner wall of the powder hopper 3, and a groove 11 is formed in the inner wall of the inner cavity 8. A retaining block 10 is slidably connected to the inner wall of the groove 11. The retaining pin 13 is bolted to one side of the retaining block 10. Through the cooperation between the retaining pin 13, the retaining block 10 and the groove 11, it is convenient for the operator to adjust the position of the retaining pin 13 to adjust the spacing between the retaining blocks 10, so as to better adjust the flow rate of the falling powder.

[0038] Next, to facilitate weighing the powder during dispensing, a horizontal plate 2 is bolted to one side of the base 1. An electronic scale 5 is mounted on top of the horizontal plate 2. A groove 21 is formed on the top of the horizontal plate 2, and a sliding groove 22 is formed on the inner wall of the groove 21. A spring 24 is welded to the inner wall of the sliding groove 22. A damper is provided on one side of the spring 24, and a slider 23 is welded to one side of the spring 24. Through the cooperation of the slider 23, the spring 24, and the sliding groove 22, the electronic scale 5 can be clamped and placed inside the horizontal plate 2. The depth of the groove 21 is used to facilitate weighing the powder during dispensing.

[0039] Meanwhile, in order to facilitate better packaging of powder by the device, specifically, the top of the powder hopper 3 is provided with a feed inlet 4 and the bottom of the powder hopper 3 is provided with a discharge outlet 25. Through the structural design of the feed inlet 4 and the discharge outlet 25, it is convenient for the device to better package the powder.

[0040] Furthermore, in order to ensure that the powder flows more evenly to the discharge port 25, specifically, a motor 6 is bolted to the top of the powder hopper 3, and a stirring shaft 7 is inserted into the output end of the motor 6. A stirring plate 9 is bolted to the outer circumference of the stirring shaft 7. The motor 6 drives the rotating shaft to stir the stirring plate 9 to stir the powder in the inner cavity 8, so as to facilitate the powder to flow more evenly to the discharge port 25.

[0041] It is worth noting that, in order to adjust the amount of powder flowing out of the discharge port 25, there are multiple locking pins 13, which are symmetrically distributed. The multiple symmetrically distributed locking pins 13 facilitate the better adjustment of the spacing between the locking blocks 10, thereby adjusting the amount of powder flowing out of the discharge port 25.

[0042] Finally, in order to better fix the electronic scale 5 inside the groove 21, there are multiple slide grooves 22, which are symmetrically distributed. The multiple symmetrically distributed slide grooves 22 facilitate the better fixing of the electronic scale 5 inside the groove 21.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] The device or equipment models mentioned in this article may be as follows:

[0045] Motor: Y802-4;

[0046] Electronic scale: DCS-FS-50.

[0047] Combination Figures 1-5 The specific usage process of a photovoltaic powder dispensing machine according to this embodiment is as follows:

[0048] 1: When using this photovoltaic powder dispensing machine, the operator moves the device to a suitable position by moving the base 1. After pouring the powder into the hopper through the feed port 4, the motor 6 is driven, which causes the stirring shaft 7 to rotate the stirring plate 9 inside the inner cavity 8 under the action of the motor 6, so that the powder can flow to the discharge port 25. At this time, the operator can pull the locking pin 13 by holding the handle 14 inserted into the inner wall of the locking ring 12, so that the locking pin 13 drives the locking block 10 to move on the inner wall of the locking groove 11, so that the gap is opened inside the inner cavity 8, allowing the powder to flow out.

[0049] 2: When the device needs to reduce the impact of powder on the surrounding working environment, the operator can connect the vertical plate 15 to the bottom of the powder hopper 3. The external thread 19 on the inner wall of the vertical groove 18 is threaded to the internal thread 20 on the inner wall of the vertical plate 15. This makes it easy for the connecting block 16 at the bottom of the vertical plate 15 to be connected below the discharge port 25. The operator can pull the elastic tube 17 so that the bottom of the elastic tube 17 can directly contact the packaged bag, thereby effectively reducing the impact of powder splashing on the surrounding working environment.

[0050] 3: When the device needs to weigh the powder, the spring 24 drives the slider 23 to move on the inner wall of the groove 22, which makes it easier to install the electronic scale 5 inside the groove 21. This makes it easier to place the powder directly on the top of the electronic scale 5 for weighing after it is packaged, and thus it is beneficial to adjust the specific amount of powder according to the electronic scale 5.

[0051] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
