Description

Technical Field

[0001] This invention relates to the field of granule packaging technology, specifically to a granule filling machine. Background Technology

[0002] Granule packaging machines can be divided into large packaging and small packaging. They are suitable for quantitative packaging of rubber granules, plastic granules, fertilizer granules, feed granules, chemical granules, grain granules, building material granules, metal granules, and other granular materials. Packaging machinery is widely used in agricultural products, pharmaceuticals, food, daily chemicals, and other fields. The development of packaging machinery not only affects the speed of economic development but is also closely linked to economic benefits. The development direction of packaging machinery can be seen from granule packaging machines. Currently, when existing packaging equipment is in operation, the packaging bag opening is open. Especially when filling finer granules or powders, particulate dust will overflow from the bag opening. This dispersed dust can enter workers' bodies through respiration, causing adverse effects on human health. When the dust concentration in the workshop reaches a certain critical point, there is also a risk of dust explosion. Summary of the Invention

This granule filling machine has a unique structure and ingenious design. During the filling process, the opening of the packaging bag and the feeding pipe are more closely fitted, which prevents the dust inside the packaging material from overflowing. This effectively avoids dust overflow, improves the environmental protection effect of the overall device, and also reduces the risk of health and fire accidents.

The bag-retrieving suction nozzle 26 can move horizontally on the outer surface of the flip-sliding track 23. When the flip-sliding track 23 is flipped, the bag-retrieving suction nozzle 26 can be driven to make a circular motion, so as to take out the packaging bag and adjust the packaging bag from a horizontal state to a vertical state. The bag-retrieving suction nozzle 26 and the four bag-supporting suction cups hold the top of the packaging bag. The top of the packaging bag is opened by the opposite movement of the bag-retrieving suction nozzle 26 and the four bag-supporting suction cups.

[0031] The bag clamping mechanism 5 includes a clamping arm 51, a telescopic cylinder 52, and a clamping connecting seat 53. The clamping arms 51 are symmetrically installed on both sides of the feeding pipe 72. The top of the clamping arm 51 is hinged to the clamping connecting seat 53. The telescopic cylinder 52 is located between the two clamping arms 51. The two ends of the telescopic cylinder 52 are respectively hinged to the adjacent side clamping arm 51. The clamping arm 51 is hinged to the top of the telescopic cylinder 52. The lower surface of the bag clamping connecting plate 75 is fixedly installed to the top of the telescopic cylinder 52. The distance between the two clamping arms 51 can be controlled by the extension and retraction of the telescopic cylinder 52.

[0032] The vacuum heat sealing mechanism 8 includes a vacuum suction tube 81, a heat sealing clamp 82, a heat sealing power base 83, and a vacuum connecting seat 84. The heat sealing clamps 82 are symmetrically arranged on the front and rear sides above the bag turning box 31. The two heat sealing clamps 82 are located below the feeding pipe 72 and are connected together by the heat sealing power base 83. The heat sealing power base 83 can drive the two heat sealing clamps 82 to move synchronously towards each other and reset. The surface of the heat sealing power base 83 is provided with a sliding track. The two heat sealing clamps 82 move towards each other or in opposite directions on the sliding track on the surface of the heat sealing power base 83, thereby realizing the heat sealing of the packaging bag. Two vacuum suction tubes 81 are arranged horizontally between the two heat sealing clamps 82. The top of the vacuum suction tube 81 is fixedly installed with the vacuum connecting seat 84.

[0033] The trolley 62 is mounted on the inner bottom wall of the sliding semi-circular guide rail 61. There are two limiting plates 64, which are mounted on the upper surface of the inner bottom wall at both ends of the sliding semi-circular guide rail 61. The limiting plates 64 are made of elastic rubber.

[0034] Vacuum connector 84 is connected to a negative pressure source.

[0037] Specifically, during filling, the bag-picking nozzle 26 picks up the top of the packaging bag and moves it to the designated position along the flipping sliding track 23. The flipping sliding track 23 then causes the bag-picking nozzle 26 to flip. At this time, the side of the bag flipping box 31 closest to the bag feeding mechanism 2 opens. After the bag-picking nozzle 26 flips and extends, it places the packaging bag inside the bag flipping box 31. Subsequently, the bag flipping box 31 closes, and the relative movement of the bag-picking nozzle 26 and the four bag-supporting suction cups opens the top of the packaging bag. After the bag opening is open, the lifting cylinder 74 drives the feeding pipe 72 and the vacuum suction pipe 81 to extend into the packaging bag. At this time, the bag-picking nozzle 26 and the four bag-supporting suction cups retract to their original positions, and the traveling trolley 62 inside the sliding semi-circular guide rail 61... The strap half-ring 63 is pushed out and combined with the sliding half-ring guide rail 61 to form a complete ring-shaped strap, which tightens the upper end of the packaging bag and fits tightly against the feeding tube 72 to prevent dust from overflowing during filling. Simultaneously, the two clamping arms 51 and the feeding tube 72 work together to clamp the packaging bag. After filling, the feeding tube 72 rises back to its original position, and the traveling trolley 62 drives the strap half-ring 63 back to its original position. The clamping arms 51 are released and return to their original position, and the vacuum suction tube 81 falls into the bag opening to draw a vacuum into the packaging bag. Then, the heat-sealing clamp 82 moves relative to clamp the packaging bag opening and heats it to seal the bag opening. After the bag opening is sealed, the bag flipping box 31 flips on the side near the bag feeding mechanism 2 to flip and send out the packaged product.

[0038] Example 2: Please refer to Figure 2 Based on Example 1, there are multiple vibration motors 32. The vibration motors 32 drive the material bag turning box 31 to vibrate, making the material packaging in the material bag turning box 31 more compact.
