Description

Technical Field

[0001] This utility model belongs to the field of fertilizer packaging technology, specifically relating to a compound fertilizer packaging device. Background Technology

[0002] With technological advancements and changing market demands, woven bag packaging machines are constantly evolving and improving. They are developing towards greater intelligence, automation, and efficiency. A woven bag packaging machine mainly consists of a feeding device, a metering device, a sealing device, a cutting device, a counting device, and a conveying device. During operation, woven bags enter through the feeding device, where the metering device accurately measures the contents. They then enter the sealing device for sealing, and the sealed bags are cut to the required length by the cutting device. Next, they enter the counting device for quantity counting, and finally, they are conveyed out of the packaging machine. The entire process is automated, significantly improving production efficiency.

[0003] Woven bags are typically sealed by folding the opening in half before sealing. This makes the four corners of the bag quite sharp. After the woven bags are filled and stacked to a certain height, the four corners of the bag will be subjected to great pressure, making them very easy to deform and break, resulting in fertilizer leakage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a compound fertilizer packaging equipment with a simple structure and convenient and practical design. By cooperating with the bag clamping device and the bag folding device, the side of the bag opening is folded so that the bag opening presents a double-layer structure after sealing. This ensures that the four corners of the packaging bags will not deform or leak when subjected to pressure after being stacked.

[0005] A compound fertilizer packaging device includes a first slide frame, a slide shaft, a bag clamping device, and a bag folding device. Two slide shafts are connected to the first slide frame. Two bag clamping devices are symmetrically arranged and slidably connected to the slide shafts. Two bag folding devices are slidably connected to the slide shafts and cooperate with the corresponding bag clamping devices. The bag clamping device includes an adjusting frame, a linear bearing seat, a bag clamping plate, a bag blowing device, a spring, a slider, a folding plate, a cylinder, and a press-type ball buckle. The adjusting frame is connected to the slide shaft via the linear bearing seat. One end of the two bag clamping plates is connected to the adjusting frame, and the other end is connected to the bag blowing device. The slider is slidably connected to the adjusting frame and connected to the folding plate. Two springs are connected between the bag clamping plates and the slider. The cylinder is mounted on the first slide frame, and its piston rod is connected to the adjusting frame. The press-type ball buckle is mounted on the adjusting frame, located between the two bag clamping plates, and cooperates with the slider.

[0006] Preferably, the blowing bag device includes a blowing block, the blowing block having an air cavity, and the side of the blowing block away from the folding plate having a number of blowing holes in a fan shape.

[0007] Preferably, the blow block has a V-shaped folding groove on the side near the folding plate.

[0008] Preferably, the bag folding device includes a top bolt and a second slide, the second slide being slidably connected to the slide shaft, and the top bolt being connected to the second slide and cooperating with the slider.

[0009] Preferably, at least two bag blowing devices are connected between the two bag clamping plates.

[0010] Beneficial effects:

[0011] (1) The compound fertilizer packaging equipment of this utility model has a simple structure and is convenient and practical. By cooperating with the bag clamping device and the bag folding device, the side of the bag opening is folded so that the bag opening presents a double-layer structure after the packaging bag is sealed. This ensures that the four corners of the packaging bag will not deform or leak when subjected to pressure after being stacked.

Detailed Implementation

[0016] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figures 1 to 2As shown; a compound fertilizer packaging device includes a first slide frame 1, a slide shaft 2, a bag clamping device 3, and a bag folding device 4. Two slide shafts 2 are connected to the first slide frame 1. Two bag clamping devices 3 are symmetrically arranged and slidably connected to the slide shafts 2. Two bag folding devices 4 are slidably connected to the slide shafts 2 and cooperate with the corresponding bag clamping devices 3. The bag clamping device 3 includes an adjusting frame 31, a linear bearing seat 32, a bag clamping plate 33, a bag blowing device 34, a spring 35, a slider 36, a folding plate 37, a cylinder, and a press-type ball buckle. The adjusting frame 31 is connected to the slide shaft 2 through the linear bearing seat 32. One end of the two bag clamping plates 33 is connected to the adjusting frame 31, and the other end is connected to the bag blowing device 34. The slider 36 is slidably connected to the adjusting frame 31 and connected to the folding plate 37. Two springs 35... Connecting the bag clamping plate 33 and the slider 36, the cylinder is mounted on the first slide 1 and the piston rod is connected to the adjusting frame 31. The press-type ball buckle is mounted on the adjusting frame 31 and located between the two bag clamping plates 33 and cooperates with the slider 36. The bag blowing device 34 includes a blowing block 38, which has an air chamber 39. The side of the blowing block 38 away from the folding plate 37 has a fan-shaped number of blowing holes 310. The side of the blowing block 38 near the folding plate 37 has a V-shaped folding groove 311. The bag folding device 4 includes a top bolt 41 and a second slide 42. The second slide 42 is slidably connected to the slide shaft 2. The top bolt 41 is connected to the second slide 42 and cooperates with the slider 36. At least two bag blowing devices 34 are connected between the two bag clamping plates 33.

[0019] The second slide 42 and the top bolt 41 are pre-adjusted, and the contact position between the top bolt 41 and the slider 36 is adjusted. At the same time, the bag blowing device 34 is connected to the high-pressure air pipe. The two cylinders drive the two adjusting frames 31 to a certain distance, so that the bag-packing device can easily put the packaging bag into the two bag clamping devices 3. The two sides of the packaging bag opening are respectively inserted between the folding plate 37 and the two bag clamping plates 33 of the two bag clamping devices 3. Then the cylinders drive the two adjusting frames 31 until the slider 36 contacts the top bolt 41. At the same time, the packaging bag opening is straightened, so that the top bolt 41 pushes the slider 36 to make the press-type ball buckle close. The two parts of the press-type ball buckle are respectively installed on the slider 36 and the adjusting frame 31. After the press-type ball buckle is closed, one side of the packaging bag opening will be clamped between the folding plate 37 and the V-shaped folding groove 311. At this time, both sides of the packaging bag opening are open. In the folded state, the cylinder drives the two adjusting frames 31 to move closer together, while the high-pressure air pipe introduces high-pressure gas into the air chamber 39. The high-pressure gas is then blown out through the blow hole 310, which blows open the bag opening, making it easier for the feeding device's outlet to be inserted. The clamping device then holds the bag. After bagging is completed, the feeding device's outlet retracts. Finally, the first slide 1 moves laterally, allowing the bag to enter the sealing device. Then, the cylinder drives the two adjusting frames 31 to move away from each other, causing the top bolt 41 to push the slider 36 to press the press-type bead buckle, separating the press-type bead buckle. Finally, the cylinder drives the two adjusting frames 31 to move closer together, and the first slide 1 moves vertically, causing the folding plate 37 and the two clamping plates 33 to move out from the position between the two folded parts of the bag opening, preventing the folding plate 37 and the two clamping plates 33 from moving out from the folded part of the bag opening and getting caught on the bag opening.
