Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, and in particular to a large bag packaging machine that can automatically fill nitrogen gas. Background Technology

[0002] A vacuum packaging machine is a device that automatically removes air from a packaging bag and seals it after reaching a predetermined vacuum level. It can also be refilled with nitrogen or other mixed gases before sealing.

[0003] The operator places the items to be packaged into a packaging bag, then puts the packaging bag into the sealed chamber of the vacuum packaging machine, and then uses a pressure bar to press the packaging bag closed.

[0004] Since the packaging bags are placed manually, they are sometimes not placed straight enough and are slightly crooked. This causes wrinkles and unevenness at the sealing point, and the seal is not straight. The uniformity of the packaging bags is poor, which affects product quality. Therefore, a new large bag packaging machine that can automatically fill nitrogen is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a large bag packaging machine that can automatically fill nitrogen gas, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a large bag packaging machine that can automatically fill nitrogen gas, including a machine body, a working chamber, a swing arm, and a chamber cover;

[0008] The top of the machine body is provided with two working chambers. The output end of the machine body is fixedly connected to a swing arm. The top inner side of the swing arm is movably connected to a chamber cover, which can be tightly closed on the top surface of either working chamber.

[0009] A vacuum tube is connected to one side of the working chamber, and a vacuum pump is connected to the end of the vacuum tube.

[0010] A positioning platform is fixedly connected to the inner edge of the working chamber, and the top surface of the positioning platform is an inclined surface;

[0011] The inner side of the working chamber is movably connected to a pressure rod via a torsion spring shaft. The pressure rod integrates a heating wire and abuts against the top surface of the positioning platform.

[0012] A connector is fixedly connected to the inside of the working chamber, and an air inflator is fixedly connected to one side of the connector. The air inflator is integrated with an air inflator head.

[0013] A main sleeve is fixedly connected to the middle of the bottom surface inside the working chamber. The main sleeve has an open structure at both ends. Telescopic rods are movably connected to both ends of the main sleeve. A fixing plate is fixedly connected to the end of the telescopic rod. A tail positioning plate is detachably connected to one side of the fixing plate.

[0014] The top surface of the main sleeve is threaded with a locking pin, and the bottom end of the locking pin abuts against the top surface of the telescopic rod.

[0015] Preferably, as described in any of the above embodiments, a platform is mounted on the side of the machine body, and a nitrogen tank is mounted on the top surface of the platform.

[0016] The above technical solution utilizes a device specifically designed for food and agricultural product packaging. The packaging method involves first vacuuming the packaging bag and then filling it with nitrogen. For example, filling bread packaging bags with nitrogen can extend shelf life, as nitrogen is an inert gas and will not chemically react with the components of food. Filling with nitrogen effectively isolates oxygen, thereby inhibiting the growth and reproduction of microorganisms (such as bacteria and mold), reducing the risk of food spoilage, and significantly extending the shelf life of food. Filling the packaging bag with nitrogen also increases its rigidity and stability, preventing the bread from being crushed inside the bag and thus maintaining its good appearance.

[0017] Preferably, in any of the above embodiments, the nitrogen tank is equipped with an air pump at its output end, the air pump is equipped with a filter and a valve at its output end, and the air pump is connected to a connector at its output end.

[0018] Using the above technical solution: The working process of this device is as follows: Adjust the position of the tail positioning plate according to the length of the packaging bag, specifically adjust the extension length of the telescopic rod, and then rotate the locking pin to make the locking pin press against the telescopic rod;

[0019] The worker places the plastic-sealed bag containing the product into the working chamber, with the tail end of the bag against the tail positioning plate. The sealed end of the bag is placed on the positioning platform, and the sealed end is fitted onto the inflation plate. The seal is then pressed down with a pressure rod. The machine is started, the swing arm moves, the chamber lid closes, sealing the working chamber. The vacuum pump begins to work, extracting air from the sealed chamber. The purpose of this step is to reduce the amount of air inside the packaging bag. As the vacuum pump continues to work, the air inside the packaging bag is gradually extracted, and the vacuum level inside the bag gradually increases.

[0020] Then, the air pump on the nitrogen tank operates, drawing out nitrogen gas, which is then diverted and controlled by valves before being output through the inflation plate, automatically filling the packaging bag with nitrogen. After inflation, because the pressure rod has an integrated heating wire, the pressure rod is heated by electricity, melting and sealing the seal of the packaging bag, completing the sealing process. After sealing, the lid opens electrically, completing one work cycle. At this point, the vacuum-packed items can be removed from the machine.

[0021] The device automatically completes the vacuuming, nitrogen filling, and sealing processes for product packaging bags.

[0022] Preferably, the inflatable sheet is made of stainless steel, and there are several inflatable sheets arranged in a linear array on the connector.

[0023] Preferably, in any of the above solutions, the main sleeve has a hollow structure, and the fixing plate and the tail positioning plate are connected by internal hex bolts.

[0024] The above technical solution employs a combination of a main sleeve, a telescopic rod, a fixing plate, a tail positioning plate, and a locking pin. The position of the tail positioning plate is adjusted according to the length of the packaging bag; specifically, the extension length of the telescopic rod is adjusted, and then the locking pin is rotated to press against the telescopic rod. The tail positioning plate positions the tail of the product packaging bag, with the tail end of the plastic-sealed bag resting against it. The seal of the plastic-sealed bag rests on the positioning plate, and the seal is placed on the positioning platform. The design of the tail positioning plate ensures that all plastic-sealed bags arranged in a straight line are aligned correctly, assisting in correcting the posture of the plastic-sealed bags. This ensures that the seal of the plastic-sealed bag fully contacts the pressure rod, guaranteeing accurate sealing, a smooth seal without wrinkles, thereby improving the sealing performance and integrity of the seal and reducing rework and waste caused by poor sealing.

[0025] The tail positioning plate is adjustable to accommodate plastic bags of different lengths, making it flexible to use.

[0026] Preferably, in any of the above embodiments, the tail positioning plate is movably connected to the bottom surface inside the working chamber, and a fastening head is fixedly connected to the top of the locking pin.

[0027] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0028] This automatic nitrogen-filling large bag packaging machine, through the coordinated arrangement of a main sleeve, telescopic rod, fixed plate, tail positioning plate, and locking pin, adjusts the position of the tail positioning plate according to the length of the packaging bag. Specifically, it adjusts the extension length of the telescopic rod, then rotates the locking pin to press against the telescopic rod, positioning the tail of the product packaging bag. The tail end of the plastic-sealed bag rests against the tail positioning plate, and the sealing end of the plastic-sealed bag is placed on the positioning platform. The design of the tail positioning plate ensures that all product plastic-sealed bags arranged in a straight line are aligned, assisting in correcting the posture of the plastic-sealed bags, and ensuring that the seal of the plastic-sealed bag fully contacts the pressure rod, guaranteeing accurate sealing position, a flat and wrinkle-free seal, thereby improving the sealing performance and integrity of the seal and reducing rework and waste caused by poor sealing.

[0038] like Figure 1-4 As shown, this large bag packaging machine that can automatically fill nitrogen includes a machine body 1, a working chamber 2, a swing arm 3, and a chamber cover 4;

[0039] The top of the machine body 1 is provided with two working chambers 2. The output end of the machine body 1 is fixedly connected to a swing arm 3. The inner side of the top of the swing arm 3 is movably connected to a chamber cover 4. The chamber cover 4 can be tightly closed on the top surface of either working chamber 2.

[0041] A positioning platform 6 is fixedly connected to the inner edge of the working chamber 2, and the top surface of the positioning platform 6 is a slope.

[0042] The inner side of the working chamber 2 is movably connected to the pressure rod 7 via a torsion spring shaft. The pressure rod 7 integrates an electric heating wire and abuts against the top surface of the positioning platform 6.

[0043] The inner side of the working chamber 2 is fixedly connected to a connector 8, and an air inflator 9 is fixedly connected to one side of the connector 8. The air inflator 9 integrates an air inflator head.

[0044] A main sleeve 10 is fixedly connected to the middle of the bottom surface inside the working chamber 2. The main sleeve 10 has an open structure at both ends. Telescopic rods 11 are movably connected to both ends of the main sleeve 10. A fixing plate 12 is fixedly connected to the end of the telescopic rod 11. A tail positioning plate 13 is detachably connected to one side of the fixing plate 12.

[0045] The top surface of the main sleeve 10 is threaded with a locking pin 14, and the bottom end of the locking pin 14 abuts against the top surface of the telescopic rod 11.

[0046] Example 1: A platform 15 is mounted on the side of the machine body 1, and a nitrogen tank 16 is mounted on the top surface of the platform 15. This device is specifically designed for food and agricultural product packaging. The packaging method employed by this device involves first vacuuming the packaging bag and then filling it with nitrogen. For example, filling a bread packaging bag with nitrogen can extend its shelf life, as nitrogen is an inert gas and will not chemically react with the components in the food. Filling with nitrogen can effectively isolate oxygen, thereby inhibiting the growth and reproduction of microorganisms (such as bacteria and mold), reducing the risk of food spoilage, and significantly extending the shelf life of the food. Filling the packaging bag with nitrogen can increase the hardness and stability of the packaging bag, preventing the bread from being squeezed and broken inside the packaging bag, thus maintaining its good appearance. An air pump is installed at the output end of the nitrogen tank 16, and a filter and valve are installed at the output end of this air pump. The output end of this air pump is connected to a connector 8.

[0047] Example 2: The inflatable sheet 9 is made of stainless steel, and several inflatable sheets 9 are arranged in a straight line on the connector 8.

[0048] The working principle of this utility model is as follows:

[0049] Adjust the position of the tail positioning plate 13 according to the length of the packaging bag, specifically by adjusting the extension length of the telescopic rod 11, and then rotating the locking pin 14 to make the locking pin 14 press against the telescopic rod 11.

[0050] The worker places the plastic-sealed bag containing the product into the working chamber 2, with the tail end of the bag abutting against the tail positioning plate 13. The sealed end of the bag rests on the positioning platform 6, and the sealed end is then placed over the inflation plate 9. The seal is then pressed down by the pressure rod 8. The machine is started, the swing arm 3 moves, and the chamber cover 4 closes, sealing the working chamber 2. The vacuum pump then begins to operate, extracting air from the sealed working chamber 2. The purpose of this step is to reduce the amount of air inside the packaging bag. As the vacuum pump continues to operate, the air inside the packaging bag is gradually extracted, and the vacuum level inside the bag gradually increases.

[0051] Then, the air pump on nitrogen tank 16 operates, drawing out nitrogen gas, which is then diverted and controlled by valves before being output through inflation plate 9, automatically filling the packaging bag with nitrogen. After inflation, because the pressure rod 7 has an integrated heating wire, it is heated by electricity, melting and sealing the seal of the packaging bag, completing the sealing process. After sealing, the lid opens electrically, completing one work cycle. At this point, the vacuum-packed items can be removed from the machine.

[0052] The device automatically completes the vacuuming, nitrogen filling, and sealing processes for product packaging bags.

[0053] Compared with the prior art, the present invention has the following advantages:

[0054] This automatic nitrogen-filling large bag packaging machine, through the coordinated arrangement of the main sleeve 10, telescopic rod 11, fixed plate 12, tail positioning plate 13, and locking pin 14, adjusts the position of the tail positioning plate 13 according to the length of the packaging bag. Specifically, it adjusts the extension length of the telescopic rod 11, and then rotates the locking pin 14 to make the locking pin 14 press against the telescopic rod 11. The tail positioning plate 13 positions the tail of the product packaging bag, and the tail end of the plastic bag abuts against the tail positioning plate 13. The seal of the plastic bag is placed on the positioning platform 6. The design of the tail positioning plate 13 ensures that all the product plastic bags arranged in a straight line can be aligned, assists in correcting the posture of the plastic bags, and ensures that the seal of the plastic bag can fully contact the pressure rod 7, ensuring accurate sealing position, flat and wrinkle-free seal, thereby improving the sealing performance and integrity of the seal and reducing rework and waste caused by poor sealing.
