Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer bagging technology, specifically a quantitative bagging device. Background Technology

[0002] Currently, various quantitative bagging devices for organic fertilizers have emerged in the industry. These devices typically achieve basic quantitative bagging through a "feeding-weighing-bag transfer" process, replacing manual bagging to some extent and improving production efficiency. However, due to the loose, porous nature of organic fertilizers and the large gaps between particles, existing devices generally suffer from incomplete packing during practical applications, specifically manifested in the following aspects:

[0003] As organic fertilizer falls from the weighing component into the packaging bag, it relies mainly on its own gravity to fill naturally. The material particles cannot fill the gaps inside the packaging bag on their own, resulting in storage space inside the packaging bag. The packaging bag is still in a "virtual full" state, and the actual effective amount of organic fertilizer it can hold is far less than the design capacity of the packaging bag. This also indirectly increases the cost of packaging bags, transportation, and warehousing.

[0004] In summary, existing organic fertilizer quantitative bagging devices suffer from significant issues with incomplete material packing, severely impacting the quality, efficiency, and economic viability of organic fertilizer bagging and subsequent distribution processes. Therefore, developing a quantitative bagging device that solves the problem of incomplete packing while maintaining both quantitative accuracy and bag density has become a pressing technological need in the field of organic fertilizer production equipment. To this end, we propose a quantitative bagging device. Utility Model Content

After filling, the lower pressure plate applies pressure a second time to reduce the gaps inside the bag, avoid packaging bag waste, and reduce transportation and storage costs.

[0020] 2. The spiral feeding blades feed material at a uniform speed to prevent overfeeding. The weighing sensor detects the weight in real time. Once the weight reaches the standard, the sealed shell closes and the cover door opens. The error is small and meets the industrial quantitative standards.

[0021] 3. Stable bag clamping to prevent leakage and improve reliability: The clamping ring and side clamping blocks clamp the bag opening from the circumference and side, and the sliding plate guide ensures that the packaging bag does not deviate when rising and falling, avoiding material drop and leakage;

[0022] 4. After the positioning frame secures the packaging bag, the transfer cylinder moves it to the conveyor belt to connect with subsequent production steps, reducing manual intervention and speeding up the mass production process. Attached Figure Description

[0042] A lifting cylinder 36 is fixedly installed on the transfer plate 42. An adjusting plate 41 is fixedly connected to the output end of the lifting cylinder 36. An adjusting cylinder 38 is fixedly installed on the adjusting plate 41. A moving plate 40 is fixedly connected to the output end of the adjusting cylinder 38. A lowering plate 39 is fixedly connected to the moving plate 40 through several support rods. The lowering plate 39 can push the material of the packaging bag downward to help compact the material and reduce the situation of loose packaging bags.

[0043] The positioning frame 43 is fixedly connected to several first guide rods, which slide through the transfer plate 42. Several second guide rods are fixedly connected to the adjusting plate 41, which slide through the transfer plate 42. Several third guide rods are fixedly connected to the moving plate 40, which slide through the adjusting plate 41, so that the positioning frame 43, the adjusting plate 41 and the moving plate 40 can move stably.

[0044] Working principle: The operator places the empty packaging bag on the bottom of the clamping shell 16 of the bag clamping assembly; then the bag clamping assembly 4 is activated, the clamping cylinder 21 drives the two sets of push arms 20 to rotate, and through the connecting rod 25 drives the connecting plate 23 and the clamping ring 24 to retract, which, together with the side clamping block 22, firmly clamps the opening of the packaging bag to prevent the packaging bag from shifting or leaking during the filling process.

[0045] Then, the weighing and feeding assembly 2 is started, and the organic fertilizer in the collection shell 7 enters the cylinder shell 11. The feeding motor 8 drives the rotating rod and the spiral feeding blade 9 to rotate, and the organic fertilizer is evenly transported to the feeding shell 10 and falls into the weighing shell 26 of the weighing assembly 3 below. The weighing sensor 33 on the welding plate 34 on both sides of the weighing shell 26 detects the weight of the material in real time. When the weight reaches the set value, the feeding cylinder 15 drives the push rod 14, which drives the rotating plate 12 and the sealing shell 13 on the feeding shell 10 to close and stop feeding. The spiral feeding blade 9 can avoid the material from being fed directly by gravity, which would result in excessive feeding.

[0046] After weighing and unloading, the closing cylinder 27 of the weighing component 3 drives the lifting block 30 to rise, and drives the cover 31 of the bottom discharge port of the weighing shell 26 to rotate and open around the mounting rod 32 via the hinge rod 29; the weighed organic fertilizer falls into the packaging bag clamped below through the clamping shell 16; during the unloading process, the downward cylinder 17 drives the lifting plate 18, the clamping shell 16, and the packaging bag to move up and down repeatedly, so that the bottom of the packaging bag contacts and collides with the bottom plate 6 multiple times, and uses the impact force to initially compact the loose organic fertilizer in the bag and reduce the gaps;

[0047] After the packaging bag is filled, the material pressing and transfer component 5 is activated. First, the lifting cylinder 36 moves the adjusting plate 41 and the pressing plate 39 to a suitable height. Then, the adjusting cylinder 38 pushes the moving plate 40 so that the pressing plate 39 is close to the top side wall of the packaging bag. Subsequently, the lifting cylinder 36 moves the pressing plate 39 slowly downward to compact the organic fertilizer in the bag a second time, further eliminating material gaps and completely avoiding the problem of "empty" packaging bags.

[0048] After secondary compaction, the positioning cylinder 44 drives the positioning frame 43 to move closer to the packaging bag and fix the packaging bag in position; then the transfer cylinder 37 pushes the transfer plate 42, the positioning frame 43, and the packaging bag to move, transferring the full and compacted organic fertilizer bag to the conveyor belt 45 on one side of the bottom plate 6, and the conveyor belt 45 transports it to the subsequent sealing stage to complete the quantitative bagging process.
