Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the embodiments, by Figure 1 and Figure 2 A sealing mechanism for a solid fertilizer bagging machine is provided, comprising a back plate 1, a sealing mechanism 2 fixedly connected to the front end of the back plate 1, and an anti-retention wire 3 located above the sealing mechanism 2 fixedly connected to the front end of the back plate 1, the end of the anti-retention wire 3 being arc-shaped.

[0020] The sealing mechanism 2 includes a mounting plate 21. Two mounting plates 21 are fixedly connected to the front end of the back plate 1. Support plates 22 are fixedly connected to the front end of the two mounting plates 21. The two support plates 22 are fixedly connected to each other by two guide rods 23. A right sealing seat 24 is fixedly connected to the outside of the two guide rods 23. A right heat sealing block 25 is fixedly connected to the left end of the right sealing seat 24. A left sealing seat 26 is slidably connected to the outside of the two guide rods 23. A left heat sealing block 27 is fixedly connected to the right end of the left sealing seat 26. A drive mechanism 28 for driving the left sealing seat 26 to move is provided between the left support plate 22 and the left sealing seat 26.

[0021] With the above settings, both the left heat-sealing block 27 and the right heat-sealing block 25 contain resistance wires, which can heat the left heat-sealing block 27 and the right heat-sealing block 25. When the packaging bag is transferred between the left heat-sealing block 27 and the right heat-sealing block 25, the driving mechanism 28 drives the left sealing seat 26 to move to the right along the outside of the two guide rods 23 until the left heat-sealing block 27 and the right heat-sealing block 25 clamp the packaging bag and complete the heat sealing by heating. During this process, the anti-retention wire 3 squeezes the packaging bag above to prevent the packaging bag above from sticking to the left heat-sealing block 27 or the right heat-sealing block 25.

[0022] Reference Figure 1 and Figure 2 The drive mechanism 28 includes a cylinder 281. The cylinder 281 is fixedly connected to the right end of the left support plate 22. The cylinder push rod 282 is slidably connected to the inner side of the cylinder 281. The right end of the cylinder push rod 282 is fixedly connected to a movable seat 283. The movable seat 283 is slidably connected to the outer side of the two guide rods 23. The movable seat 283 and the left sealing seat 26 are connected by two spiral connectors 284. The two spiral connectors 284 are respectively sleeved on the outer side of the two guide rods 23.

[0023] With the above-mentioned structural configuration, when the cylinder 281 is activated, the cylinder push rod 282 pushes out, causing the movable seat 283 to move to the right, causing the spiral connector 284 to move to the right, thereby causing the left sealing seat 26 to move quickly to the right and clamp the packaging bag between the left heat sealing block 27 and the right heat sealing block 25, thus completing the heat sealing operation.

[0024] Reference Figure 1 and Figure 2 Among them, the inner side of the left sealing seat 26 is fixedly connected to two fixing rods 4, and both fixing rods 4 are fixedly connected to the cutting blade 5;

[0025] With the above structural setup, when the left sealing seat 26 moves to the right, it will drive the cutting blade 5 to move to the right. Since the packaging bag is heated and deformed, the cutting blade 5 can easily cut off the packaging bag.
