Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer raw material packaging technology, specifically a raw material packaging device for water-soluble fertilizer production. Background Technology

[0002] There are two main categories of water-soluble fertilizer raw materials: inorganic water-soluble fertilizer raw materials and organic water-soluble fertilizer raw materials. The raw materials are further divided into liquid raw materials and solid raw materials. Nitrogen fertilizers include phosphorus nitrate, diammonium hydrogen phosphate, urea, ammonium sulfate, ammonium chloride, ammonium nitrate, and ammonium bicarbonate. Nitrogen fertilizers have strong hygroscopic properties and are completely soluble in water. However, sulfate ions will react with calcium and magnesium ions in the water to produce insoluble sulfates. In the production process of water-soluble fertilizer raw materials, they need to be packaged. Therefore, a raw material packaging device for water-soluble fertilizer production is provided.

[0003] For example, in the case of the product with announcement number "CN221794993U", as fertilizer falls into the packaging bag, the weight of the support plate continuously increases. This causes the support plate to press down on the spring via the connecting block, lowering the height of the pressure plate. This, in turn, presses the button switch, which sends a signal to the discharge valve, closing it and filling the packaging bag with the set weight of fertilizer, thus reducing the weight difference between each bag. However, this method of using the weight of the water-soluble fertilizer to press the spring and trigger the switch for quantitative control of the water-soluble fertilizer raw material cannot precisely measure different dosages according to different needs. This results in significant packaging limitations and a lack of sealing capabilities. After the water-soluble fertilizer is filled, the packaging bag needs to be manually sealed by staff, leading to low practicality. Utility Model Content

[0004] The purpose of this invention is to address the problem that methods for quantitatively dispensing water-soluble fertilizers according to different needs have limited packaging capabilities and lack sealing performance. After the water-soluble fertilizer is filled, subsequent staff need to manually seal the packaging bag, resulting in low practicality. Therefore, this invention proposes a raw material packaging device for water-soluble fertilizer production.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a raw material packaging device for water-soluble fertilizer production, including a frame, a water tank, and a box body. The upper end of the outer wall of the frame is fixedly connected to the water tank. The lower end of the outer wall of the water tank is provided with a quantitative adjustment structure for water-soluble fertilizer raw materials. The outer walls of the two boxes are provided with packaging bag sealing structures. The upper left side of the water tank is fixedly connected to the feed inlet. A third electric telescopic rod is fixedly connected to the middle of the upper end of the inner wall of the water tank. A rubber plate is fixedly connected to the output end of the third electric telescopic rod.

[0007] Preferably, the water-soluble fertilizer raw material quantitative adjustment structure includes a second electric telescopic rod, the output end of which is fixedly connected to a frame, a first vertical pipe is fixedly connected to the middle of the inner wall of the frame, a piston is fixedly connected to the upper end of the outer wall of the first vertical pipe, the outer wall of the piston is sealed to the second vertical pipe, and the upper end of the second vertical pipe is fixedly connected to the water tank.

[0008] Preferably, the bottoms of the two second electric telescopic rods are fixedly connected to the water tank, and the lower end of the inner wall of the frame is fixedly connected to the tank body through a bracket.

[0009] Preferably, the packaging bag sealing structure includes a motor, a threaded rod is fixedly connected to the end of the motor output shaft, the outer wall of the threaded rod is threadedly connected to a threaded seat, two sliding rods are fixedly connected to the outer wall of the threaded seat, a concave plate is fixedly connected to the end of the sliding rod, and a first electric telescopic rod is fixedly connected to both sides of the lower end of the frame, and a heating plate is fixedly connected to the output end of the first electric telescopic rod.

[0010] Preferably, the outer walls of the two motors are fixedly connected to the housing via brackets, and the two ends of the threaded rod are rotatably connected to the housing via bearings.

[0011] The present invention discloses a raw material packaging device for water-soluble fertilizer production, which has the following advantages: Through the packaging bag sealing structure, the first motor starts and drives the threaded rod to rotate in the box through the bearing. The rotation of the two threaded rods drives the threaded seat to move relative to each other, and then drives the sliding rod to slide relative to each other through the threaded seat. The sliding rod drives the concave plate to move relative to each other. The heating plate is activated to energize the internal heating wire. The heating wire generates heat and transfers it to the heating plate to heat it. The two first electric telescopic rods are activated and drive the heating plate to move relative to each other to perform heat-sealing of the packaging bag. The two first motors finally drive the concave plate to move relative to each other to limit the packaging bag. Then, the two first electric telescopic rods drive the heating plate to move relative to each other to perform heat-sealing of the packaging bag. This effectively reduces the number of manual steps for sealing the packaging bag, thereby improving its practicality.

[0012] The water-soluble fertilizer raw material quantitative adjustment structure activates two second electric telescopic rods to move the frame downwards, which in turn moves the first vertical tube downwards. The downward movement of the first vertical tube causes the piston to slide downwards within the second vertical tube. Finally, the second electric telescopic rods move the first vertical tube and the piston downwards within the second vertical tube, increasing the dosage of water-soluble fertilizer raw material stored inside the first and second vertical tubes. This makes it suitable for quantitative packaging of water-soluble fertilizers of different dosages, effectively reducing the limitations of water-soluble fertilizer raw material packaging.

[0026] Working principle:

[0027] Quantitative adjustment of raw material packaging for water-soluble fertilizer production:

[0028] When it is necessary to quantitatively package the water-soluble fertilizer raw material, open the valve in the middle of the inlet to introduce an appropriate amount of water-soluble fertilizer raw material into the water tank 4 and close the valve. At this time, the water-soluble fertilizer raw material will flow into the second vertical pipe 204 and the first vertical pipe 203. Then, connect the power cords of the two second electric telescopic rods 201 to the control board at the same time, and connect the external power supply of the two second electric telescopic rods 201. The two second electric telescopic rods 201 start to drive the frame 202 to move downward, and then drive the first vertical pipe 203 to move downward through the frame 202. The downward movement of the first vertical pipe 203 drives the piston 205 to slide downward in the second vertical pipe 204. This movement can adjust the storage space inside the first vertical pipe 203 and the second vertical pipe 204, thereby adjusting the quantitative dosage of the water-soluble fertilizer raw material. When the quantitative dosage of the water-soluble fertilizer raw material is adjusted, the second electric telescopic rods 201 stop moving.

[0029] Packaging of raw materials for water-soluble fertilizer production:

[0030] After the quantitative dosage of the water-soluble fertilizer raw material is adjusted, the packaging bag is placed on the lower end of the first vertical pipe 203. Then, the external power supply of the two first motors 101 is turned on. The first motors 101 start and drive the threaded rods 102 to rotate in the box 8 through the bearings. The rotation of the two threaded rods 102 drives the threaded seats 103 to move relative to each other. Then, the threaded seats 103 drive the sliding rods 104 to slide relative to each other. The sliding rods 104 drive the concave plates 105 to move relative to each other. When the concave plates 105 abut against the packaging bag placed on the lower end of the first vertical pipe 203, the first motors 101 stop moving. This movement can limit the movement of the packaging bag. Then, the external power supply of the third electric telescopic rod 6 is turned on. The third electric telescopic rod 6 starts and drives the rubber plate 7 to move downward and abut against the second vertical pipe 204 and the water tank 4. This movement can seal the second vertical pipe 204.

[0031] Then, the solenoid valve in the middle of the first vertical pipe 203 is opened. At this time, the water-soluble fertilizer raw material inside the first vertical pipe 203 will flow into the packaging bag for filling. Then, the external power supply of the two heating plates 107 is connected. The heating plates 107 are started to energize the internal heating wires. The heating wires generate heat and transfer it to the heating plates 107 to heat them. Then, the external power supply of the two first electric telescopic rods 106 is connected. The two first electric telescopic rods 106 are started to drive the heating plates 107 to move relative to each other to perform heat-sealing of the packaging bag.

[0032] Subsequently, the two first motors 101 are reversed to reset the concave plate 105 and release the limiting position on the packaging bag. At the same time, the packaging bags of the water-soluble fertilizer raw materials can be collected. The solenoid valve in the middle of the first vertical pipe 203 is closed, and the third electric telescopic rod 6 is controlled to drive the rubber plate 7 to reset, so that the water-soluble fertilizer raw materials inside the vertical pipe 7 flow back into the first vertical pipe 203 and the second vertical pipe 204 for quantitative measurement. Then, the subsequent packaging bag is put on the lower end of the first vertical pipe 203, and the subsequent quantitative packaging work is carried out in the same way as above.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
