[0034] A scissor jack 7 is fixedly connected to the upper surface of the body 101. The two scissor jacks 7 are symmetrically distributed with the axis of the storage tank 3 as the center. Furthermore, the scissor jack 7 is a commercially available scissor jack 7. The scissor jack 7 is a manual mechanical lifting device characterized by a scissor-shaped metal bracket.

[0036] In use, rotating the handle 10 drives the drive sprocket 8 to rotate, and the drive sprocket 8 drives the driven sprocket 9 to rotate via the chain, so that the two screws rotate synchronously and drive the two scissor jacks 7 to move synchronously.

[0037] Both scissor jacks 7 have a sealing disc 11 fixedly connected to their upper surfaces. A first feeding control disc 12 is slidably connected to the upper surface of the sealing disc 11.

A positioning column 14 is slidably connected to the inner wall of the positioning tube 13. One end of the positioning column 14 is fixedly connected to the upper surface of the machine body 101.

[0038] In use, the positioning tube 13 rotates with the sealing disc 11, so that the positioning tube 13 can drive the first feeding control disc 12 to rotate and always keep it in contact with the sealing disc 11.

The surface of the first drive gear 20 meshes with the surface of the first transmission gear 16. The gear ratio between the first drive gear 20 and the first transmission gear 16 is 1:16.

[0041] In use, the drive motor 18 drives the power shaft 19 to rotate, the power shaft 19 drives the first drive gear 20 to rotate, the first drive gear 20 rotates four times, drives the first transmission gear 16 to rotate a quarter turn, drives the driven gear cylinder 15 to rotate a quarter turn, and drives the positioning tube 13 and the first unloading control disc 12 to rotate a quarter turn.

[0042] One end of the power shaft 19 passes through and extends to the upper surface of the drive bracket 4. The surface of the power shaft 19 is rotatably connected to the surface of the drive bracket 4 through bearings. Multiple positioning bearing seats are rotatably connected to the surface of the power shaft 19 through bearings. The surfaces of the multiple positioning bearing seats are fixedly connected to the surface of the storage bucket 3.

[0043] In use, the power shaft 19 is rotated and positioned by fixing the positioning bearing seat to the surface of the storage tank 3.

[0044] A second drive gear 21 is fixedly sleeved on the surface of the power shaft 19. The second drive gear 21 is located above the storage hopper 3. A second transmission gear 22 meshes with the surface of the second drive gear 21. A second transmission column 23 is rotatably connected to the inner wall of the drive bracket 4 through a bearing. The surface of the second transmission gear 22 is fixedly sleeved with the surface of the second transmission column 23.

[0045] A driven gear 24 is fixedly sleeved on the surface of the drive shaft 5. The surface of the driven gear 24 meshes with the surface of the second transmission gear 22. The tooth ratio of the driven gear 24 to the second transmission gear 22 is 1:4, and the tooth ratio of the second transmission gear 22 to the second drive gear 21 is 1:2.

[0046] In use, the second drive gear 21 is driven to rotate by the power shaft 19. The second drive gear 21 rotates once, which drives the second transmission gear 22 to rotate twice. The second transmission gear 22 rotates twice, which drives the driven gear 24 to rotate eight times. The driven gear 24 drives the drive shaft 5 and the scraper 6 to rotate eight times.

[0047] The lower surface of the storage hopper 3 is rotatably connected to a connecting pipe 25 via a bearing. A second feeding control disc 26 is fixedly sleeved on the surface of the connecting pipe 25. The upper surface of the second feeding control disc 26 is slidably connected to the lower surface of the storage hopper 3.

[0048] The surfaces of the first feeding control disk 12 and the second feeding control disk 26 are both fixedly provided with feeding holes. The eight feeding holes are arranged in a circular array with the axis of the first feeding control disk 12 and the second feeding control disk 26 as the center. The inner walls of the four feeding holes on the surface of the second feeding control disk 26 are fixedly connected to the first quantitative tubes 27. The surfaces of the four first quantitative tubes 27 are slidably sleeved with the second quantitative tubes 28. One end of the four second quantitative tubes 28 is fixedly connected to the upper surface of the first feeding control disk 12. The inner walls of the four second quantitative tubes 28 are fixedly connected to the inner walls of the four feeding holes on the first feeding control disk 12.

[0049] Furthermore, all four first quantitative tubes 27 and four second quantitative tubes 28 are made of transparent plastic tubes. In order to facilitate the verification of the feeding amount, the surface of each of the four first quantitative tubes 27 is provided with a scale. The top of the second quantitative tube 28 is matched with the scale to realize the quantitative filling and feeding of fertilizer.

[0050] The inner bottom wall of the storage tank 3 is fixedly provided with a discharge hole 29, and the surface of the sealing plate 11 is fixedly provided with a filling hole 30. The inner walls of the filling hole 30 and the discharge hole 29 are connected to the inner wall of the discharge hole. The filling hole 30 is located above the molding device 104 and is concentric with the top of the molding device 104.

[0051] The inner wall of the connecting pipe 25 is rectangular, and a connecting post 31 with a surface adapted to the inner wall of the connecting pipe 25 is slidably connected to the inner wall of the connecting pipe 25. The bottom of the connecting post 31 is fixedly connected to the upper surface of the first feeding control panel 12.

[0052] Furthermore, during use, the connecting column 31 and the connecting pipe 25 work together to ensure that the first feeding control plate 12 and the second feeding control plate 26 rotate synchronously.

[0053] By setting up a feeding control mechanism 106, during use, two scissor jacks 7 are simultaneously driven to lift and lower, adjusting the distance between the first feeding control plate 12 and the second feeding control plate 26, thereby adjusting the volume of the first quantitative tube 27 and the second quantitative tube 28, and realizing rapid adjustment of the filling volume. This solves the problem that the existing vertical three-side sealing automatic packaging machine uses screw metering, which has long adjustment time and poor adaptability when changing production.

[0054] Working principle: When filling fertilizer, the fertilizer to be filled is first poured into the storage tank 3. Then, the PLC controller in the control box 105 is programmed, and the packaging film is loaded onto the film roll bracket 103. Then, the rotating handle 10 is turned to drive the drive sprocket 8 to rotate. The drive sprocket 8 drives the driven sprocket 9 to rotate through the chain, which drives the screws on the two scissor jacks 7 to rotate synchronously, causing the scissor jacks 7 to rise or fall. This causes the sealing plate 11 and the first feeding control plate 12 to adjust their height, thereby adjusting the position of the first quantitative tube 27 in the second quantitative tube 28 and adjusting the internal volume of the first quantitative tube 27 and the second quantitative tube 28, thus controlling the filling amount of the fertilizer.

[0055] After the first quantitative tube 27 and the second quantitative tube 28 are adjusted, the PLC controller inside the control box 105 automatically controls the three-side sealing packaging machine body 1 and the drive motor 18 to work. The output shaft of the drive motor 18 drives the power shaft 19 to rotate through the coupling. The power shaft 19 simultaneously drives the first drive gear 20 and the second drive gear 21 to rotate. The second drive gear 21 drives the driven gear 24 to rotate rapidly through the second transmission gear 22, which drives the drive shaft 5 and the scraper 6 to rotate rapidly. The fertilizer inside the storage tank 3 is scraped into the first quantitative tube 27 and the second quantitative tube 28 through the discharge hole 29. Then, driven by the first drive gear 20, the first transmission gear 16 is driven to rotate, which drives the driven gear cylinder 15 to rotate, which drives the positioning tube 13 and the first feeding control plate 12 to rotate. After rotating to connect with the filling hole 30, the fertilizer falls into the forming device 104 through the filling hole 30 and enters the packaging bag formed by the roll film through the forming device 104 for filling and packaging.

[0056] The above description is merely a preferred embodiment of this utility model. Any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and inventive concept of this utility model should be included within the protection scope of this utility model.
