[0002] A midi-wrapping machine is an automated device used to package products in a continuous roll of film (also known as roll film). It is commonly used in the packaging process for industries such as food, pharmaceuticals, cosmetics, and daily necessities. The midi-wrapping machine operates as follows: First, the product is placed into the packaging machine's infeed position via a conveyor system or manually. The roll film is then stretched and conveyed to the sealing area above the product. Next, the roll film is heat-sealed to form a sealed bag or package. During sealing, the roll film is also cut as needed to ensure each package is complete.

[0053] The working principle of a medium-sized packaging machine for multiple specifications:

[0054] During use, the tubular packaging film output by the film unwinding mechanism 2 passes through the film unwinding buffer mechanism 3, the guide conveying mechanism 4, and the front sealing mechanism 5 in sequence and is fixed inside the bag making mechanism 6. The tubular packaging film passes between the two heat sealing blocks 55, and the sealing cylinder 52 is started to contract. The output end of the sealing cylinder 52 drives the first movable plate 53 to move, and the first movable plate 53 drives the sliding rod 54 to move, and the sliding rod 54 drives the heat sealing block 55 to move. The two heat sealing blocks 55 approach each other to perform the first sealing on the tubular packaging film.

[0055] The bag making mechanism 6 transports the tubular packaging film for a distance and then cuts it along the first seal to form a separate packaging bag, while clamping and fixing the tubular packaging film on the side close to the front sealing mechanism 5.

[0056] The bagging suction cup 75 on the bagging mechanism 7 absorbs and fixes the two sides of the packaging bag output by the bag making mechanism 6, and then starts the bag rubbing cylinder 76 to contract. The output end of the bag rubbing cylinder 76 drives the first swinging rod 77 to swing, and the first swinging rod 77 drives the first rotating rod 74 to rotate. The first rotating rod 74 drives the bagging suction cup 75 to rotate, and the bagging suction cup 75 opens the two sides of the packaging bag. At the same time, the first conveyor belt 71 drives the first mounting plate 72 to move toward the turntable mechanism 8, and the first mounting plate 72 drives the swinging plate 73, the first rotating rod 74, and the bagging suction cup 75 to move. The bagging suction cup 75 puts the opened packaging bag on the bag-supporting duckbill 84 above the turntable mechanism 8, and then resets the first mounting plate 72 and the bagging suction cup 75.

[0057] Start the turntable motor 82, and the output end of the turntable motor 82 drives the turntable 83 to rotate. The turntable 83 drives the bag-supporting duckbill 84 above to rotate downward, and at the same time, the bag-supporting duckbill 84 below without bag rotates upward.

[0058] At the same time, the belt on the second conveyor belt 91 conveys the stacked products to the material table 112, and the lifting and moving module 111 is started. The output end of the lifting and moving module 111 pushes the material table 112 upward and aligns it with the bag-supporting duckbill 84 below.

[0059] Then start the third conveyor belt 121, the third conveyor belt 121 drives the second mounting plate 122 to move, the second mounting plate 122 drives the connecting rod 123 to move, the connecting rod 123 drives the pushing head 124 to move, the pushing head 124 pushes the product on the material table 112 through the bag-supporting duckbill 84 into the packaging bag, and continues to push the packaging bag through between the two second movable plates 132, and then resets the pushing head 124.

[0060] Then the rear sealing motor 133 is started to rotate reciprocatingly, and the output end of the rear sealing motor 133 drives the second rotating rod 134 to rotate, and the second rotating rod 134 drives the second swinging rod 135 to swing back and forth, and the second swinging rod 135 drives the connecting rod 136 to move, and the connecting rod 136 drives the two second movable plates 132 to move closer to or away from each other, so that the trimming assembly 137 and the sealing assembly 138 on the second movable plate 132 trim and seal the packaging bag, and the sealed and packaged products are moved to the discharge conveyor belt 14 for output.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
