Description

Technical Field

[0001] This utility model relates to the field of outer packaging bag processing technology, specifically to an outer packaging bag heat-sealing vacuum packaging machine. Background Technology

[0002] Vacuum packaging machines for outer packaging bags are important equipment in the modern packaging industry, widely used in the packaging of food, pharmaceuticals, cosmetics, and other consumer goods. Their main function is to seal products in specially designed bags through heat sealing and vacuum extraction, effectively extending the product's shelf life and preventing damage to product quality from external environmental factors (such as air, moisture, and bacteria). At the same time, vacuum packaging also preserves the original flavor and nutritional components of the product, meeting consumers' demand for high-quality products.

[0003] However, although heat-sealing vacuum packaging machines for outer packaging bags have played an important role in many industries, they also have some shortcomings that cannot be ignored in practical applications.

[0004] First, insufficient air extraction or incomplete sealing during vacuum packaging may leave residual air or moisture inside the bag, affecting the product's shelf life. Second, the technical performance of the equipment and fluctuations in its operating environment (such as temperature and humidity) directly impact the vacuum level achieved and the heat-sealing effect, potentially leading to incomplete sealing and compromised packaging quality. No solutions have yet been proposed to address these technical issues. Utility Model Content

Specifically, the two cylinders 1 3 are started simultaneously to drive the two sealing blocks 4 to move closer together, thereby sealing the outer packaging bag. The cylinder 2 5 is started to drive the hot melt edge gear 1 6 to move, thereby adjusting the distance between the hot melt edge gear 1 6 and the hot melt edge gear 2 8. The drive motor 7 is started to drive the hot melt edge gear 2 8 to rotate. The two cylinders 3 9 are started simultaneously to drive the two sealing and cutting blocks 10 to move closer together, thereby sealing and cutting the outer packaging bag.

[0022] Please see Figure 1-3 As shown, the feeding mechanism further includes a cylinder 12 and a feeding nozzle 13. The cylinder 12 is mounted on the frame 1, and the feeding nozzle 13 is mounted on the output end of the cylinder 12.

[0023] In this embodiment, the start cylinder 12 can drive the feeding nozzle 13 to move up and down, so that the packaging bag can be dropped onto the bag picking mechanism as needed.

[0030] The working principle of this utility model:

[0031] The outer packaging bag is heat-sealed by a heat-sealing mechanism. Simultaneously, two cylinders (3) move two sealing blocks (4) closer together, sealing the outer packaging bag. Cylinder (5) moves the heat-melting edge gear (6), adjusting the distance between them. The drive motor (7) rotates the heat-melting edge gear (8), simultaneously activating two cylinders (9) to move two sealing and cutting blocks (10) closer together, cutting the outer packaging bag. After sealing and cutting, the bag slides onto the feeding mechanism via the feeding plate (11). Cylinder 4 12 can drive the feeding nozzle 13 to move up and down, so that the packaging bag can fall onto the bag picking mechanism as needed. Activating cylinder 8 23 can adjust the left and right position of the bag picking suction nozzle 25. Activating cylinder 9 24 can adjust the front and back position of the bag picking suction nozzle 25. The bag picking suction nozzle 25 can pick up the packaging bag and then drop it onto the forming mechanism. Activating cylinder 5 14 can drive the forming block 15 to move. Activating cylinder 6 21 can drive the fixed protrusion 22 to move. The forming block 15 and the fixed protrusion 22 cooperate to form the packaging bag.

[0032] This utility model provides a completely sealed packaging bag, preventing the entry of external air, moisture, and contaminants. It removes air from the packaging bag, slows down oxidation and bacterial growth, thereby effectively extending the product's shelf life and reducing product damage caused by physical collisions, pressure, and other factors. It enables fast and efficient packaging operations, reduces human intervention and operational errors, and thus improves the overall efficiency of the production line and reduces production costs.

[0033] Example 2

The material collection mechanism includes a cylinder 16, a collection box 17, a movable rod 18, a feeding clamp 19, and a connecting rod 20. The cylinder 16 and the collection box 17 are both mounted on the frame 1. Both ends of the collection box 17 have openings. The movable rod 18 is located inside the collection box 17. One end of the movable rod 18 passes through the opening and extends to the outside of the opening. The end of the movable rod 18 is connected to the output end of the cylinder 16 through the connecting rod 20. There are two feeding clamps 19, which are symmetrically arranged. The center of the feeding clamp 19 is movably connected to the collection box 17, and one end of the feeding clamp 19 is movably connected to the movable rod 18.

[0035] In this embodiment, activating cylinder 7 16 drives the movable rod 18 connected by connecting rod 20 to move up and down, thereby causing the two feeding clamps 19 on the collection box 17 to move closer or further apart, thus collecting or dropping the packaging bags. This automates the collection of packaged products, avoiding manual intervention and operation, thereby reducing downtime and manual handling time, improving overall production efficiency, preventing product damage or loss due to improper manual operation or handling, avoiding chaos in the packaging process, maintaining the cleanliness of the production line, and reducing the probability of clutter and errors in the packaging environment.
