[0002] Bagging and vacuuming products is a common packaging method, typically used for products susceptible to oxygen and moisture. The steps are as follows: First, place the product to be packaged into a packaging bag, then use a vacuum bag sealing machine to seal the opening of the bag; next, place the packaging bag containing the product into the vacuum chamber of the vacuum bag sealing machine for vacuuming; finally, after vacuuming, use the vacuum bag sealing machine to reseal the opening of the packaging bag and check the seal.

[0003] Although some existing vacuum bag sealing machines are equipped with conveyor systems to automatically move bags from one location to another to improve production efficiency, the above operations are not fully automated and still suffer from problems such as inconsistent sealing and vacuuming, low production efficiency, and high labor costs. Summary of the Invention

[0019] Meanwhile, the present invention also provides a method for automated bagging and vacuuming of products, characterized in that the system for automated bagging and vacuuming of products includes the following steps:

[0020] Step 1: Packaging bags are fed in a centralized manner, and the automatic bag suction system is activated;

[0021] First, the suction cylinder is controlled to move the upper suction device downward to suck up the top layer of the packaging bag on the suction platform; second, the upper suction device raises the packaging bag to the preset bag entry height, and then the first guide rail assembly is controlled to transport the packaging bag to the bagging platform; finally, the first positioning cylinder and the second positioning cylinder are used to position the two sides of the packaging bag.

[0022] Step 2: The packaging bag automatically expands;

[0023] First, the bag-opening cylinder moves the first lower suction device upward, causing it to grip the bottom of the packaging bag. Then, the bag-opening cylinder moves the first lower suction device downward, while the bag-suction cylinder moves the upper suction device upward. The first and second positioning cylinders move in opposite directions, opening the front opening of the packaging bag. Next, the first bag-supporting cylinder controls the bag-supporting fixture to extend into the front opening of the packaging bag, keeping the front opening open. Finally, the upper suction device and the first lower suction device are released simultaneously and return to their initial positions.

[0024] Step 3: Products are automatically bagged;

[0025] The product is pushed into the packaging bag through the front opening of the packaging bag by the bag-feeding motor, and then the bag-feeding motor moves backward. At the same time, the first positioning cylinder and the second positioning cylinder are controlled to release the two sides of the packaging bag containing the product and return to the corresponding initial position.

[0026] Step 4: The packaging bag is automatically vacuum-sealed;

[0027] First, the first and second transfer cylinders clamp the two sides of the product-filled packaging bag obtained in step 3, and control the second guide rail assembly to transport the product-filled packaging bag to the vacuum platform. Second, the telescopic cylinder controls the two bag-supporting fingers to extend into the front opening of the packaging bag, and the second bag-supporting cylinder controls the two bag-supporting fingers to open, while the first and second transfer cylinders release the two sides of the pre-product and return to their corresponding initial positions. When the two bag-supporting fingers are opened to their maximum position, the vacuum machine vacuums and seals the packaging bag, completing the automated product bagging and vacuuming.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (2) The present invention provides an automated bagging and vacuuming process for a product. Compared with a large amount of manual operation, the present invention occupies less space, has higher production efficiency, and reduces labor costs.

[0031] (3) The present invention provides an automated bagging and vacuuming system for a product. Multiple packaging bags can be set on the suction table. The suction table is raised and lowered by the feeding mechanism. Each time, the upper suction device picks up the top packaging bag on the suction table, eliminating the need to place the packaging bags multiple times before suctioning.

[0061] A method for automated bagging and vacuuming of products, using the aforementioned automated bagging and vacuuming system, includes the following steps:

[0062] Step 1: Packaging bags 01 are fed in a centralized manner and automatically sucked up;

[0063] First, the feeding mechanism 8 controls the suction platform 2 to rise and fall to the preset suction height, and then the suction cylinder is controlled by the suction motor to drive the upper suction device 53 to move down and suck up the top packaging bag 01 on the suction platform 2.

[0064] Next, the upper suction device 53 raises the packaging bag 01 to the preset bag entry height, and then controls the first connecting component 513 to move upward along the first vertical guide rail 512. The first vertical guide rail 512 moves horizontally along the first horizontal guide rail 511 to transport the packaging bag 01 to the bagging table 3.

[0065] Finally, the two sides of the packaging bag 01 are positioned by the first positioning cylinder 62 and the second positioning cylinder 63.

[0066] Step 2: Packaging bag 01 automatically opens;

[0067] First, the bag-opening cylinder 64 drives the first lower suction device 67 to move upward, so that the first lower suction device 67 sucks the bottom surface of the packaging bag 01. Then, the bag-opening cylinder 64 drives the first lower suction device 67 to move downward. At the same time, the bag suction motor controls the bag suction cylinder to drive the upper suction device 53 to move upward, and controls the first positioning cylinder 62 and the second positioning cylinder 63 to move in opposite directions, so that the front opening of the packaging bag 01 is opened.

[0068] Secondly, the first bag-supporting cylinder 66 controls the bag-supporting fixture 68 to extend into the front opening of the packaging bag 01, keeping the front opening of the packaging bag 01 open.

[0069] Finally, the upper suction device 53 and the first lower suction device 67 are released simultaneously and return to their corresponding initial positions;

[0070] Step 3: Products are automatically bagged;

[0071] The product is pushed into the packaging bag 01 through the front opening of the packaging bag 01 by the bag-feeding motor 61. Then the bag-feeding motor 61 moves backward, while the first positioning cylinder 62 and the second positioning cylinder 63 are controlled to release the two sides of the packaging bag 01 containing the product and return to the corresponding initial position.

[0072] Step 4: The packaging bag 01 is automatically flattened, vacuumed, and sealed;

[0073] First, the first transplanting cylinder 55 and the second transplanting cylinder 56 clamp the two sides of the packaging bag 01 containing the product obtained in step 3, and control the second connecting component 523 to move upward along the second vertical guide rail 522, and the second vertical guide rail 522 to move horizontally along the second horizontal guide rail 521, so as to transport the packaging bag 01 containing the product to the vacuum table 4.

[0074] Next, the telescopic cylinder 72 controls the two bag-holding fingers 74 to extend into the front opening of the packaging bag 01, and the second bag-holding cylinder 73 controls the two bag-holding fingers 74 to open, while the first transfer cylinder 55 and the second transfer cylinder 56 release the two sides of the pre-product and return to the corresponding initial position.

[0075] When the two bag-supporting fingers 74 are opened to their maximum position, the flipping bracket is flipped. The bracket middle 721 and the boss 41 cooperate to limit the front opening of the packaging bag 01 in the vertical direction. At the same time, the second suction device 77 sucks the bottom surface of the packaging bag 01, and the vacuum nozzle of the vacuum machine 71 is inserted into the front opening of the packaging bag 01 to draw a vacuum. Then, the second suction device 77 releases the bottom surface of the packaging bag 01 and controls the two bag-supporting fingers 74 to return to the initial position.

[0076] After vacuuming is completed, the vacuum nozzle of the vacuum machine 71 returns to its initial position. After the sealing device seals the packaging bag 01, the flipping bracket returns to its initial position, completing the automated bagging and vacuuming of the product.
