The bag storage mechanism 2 includes a bag conveying channel formed by two parallel vertical plates 21 and a push plate 22, which is located inside the bag conveying channel; under the drive of an elastic drive member, the push plate 22 pushes several packaging bags 6 sequentially to the end of the bag conveying channel so that the subsequent bag-retrieving component can pick them up and transfer them. The opening mechanism includes two symmetrically arranged bag-opening components. Under the drive of the drive component A, the two bag-opening components adsorb the sides of the packaging bag 6 and move back to open the packaging bag 6, so that the operator can put small products to be packaged into the packaging bag 6. The sealing mechanism 4 includes two opposing pressure plates 41. The inner side of each pressure plate 41 is provided with a heat-sealing strip for heat-sealing the packaging bag 6. Driven by the drive component B, the two pressure plates 41 press against both sides of the upper end of the packaging bag 6, thus heat-sealing the packaging bag 6 and sealing the upper opening of the packaging bag 6 for convenient sealing. The reciprocating conveying mechanism includes a bag-picking component and a bag-clamping component respectively installed at both ends of the horizontal conveying plate 51. The bag-picking component picks up the packaging bag 6 from the end of the bag conveying channel, and the bag-clamping component clamps the packaging bag 6 under the drive of the drive component C. Driven by the drive component D, the horizontal conveying plate 51 reciprocates between the bag storage mechanism 2, the spreading mechanism, and the sealing mechanism 4.

[0034] In this embodiment, the bag storage mechanism 2 gradually feeds the bag, the bag taking component sucks away the packaging bag 6 at the end of the bag storage mechanism 2, the horizontal transfer plate 51 moves the bag taking component to the opening mechanism, and the two bag opening components move back to back to open the packaging bag 6; when the operator puts a small product into the packaging bag 6, the horizontal transfer plate 51 moves to the right to drive the bag clamping component to clamp the packaging bag 6, and then the horizontal transfer plate 51 moves to the right to move the packaging bag 6 to the sealing mechanism 4, the two pressure plates 41 squeeze the two sides of the packaging bag 6, so that the packaging bag 6 is heat-sealed, realizing integrated automated packaging, which is convenient and efficient.

[0035] For further details, please refer to Figure 3 , Figure 5 as well as Figure 8As shown, the opening mechanism also includes a clamping assembly for clamping the packaging bag 6. The clamping assembly includes two symmetrical clamp pairs. The two clamps 31 inside the clamp pairs are respectively installed on the sides of the horizontal plates of two parallel L-shaped plates 311. Two parallel horizontal rods 32 are installed at the center of the inner top of the packaging box 1. The opening mechanism 3 is installed on the two horizontal rods 32. A first cylinder 321 is fixedly installed on the outside of the horizontal rods 32, and a second cylinder 322 is fixedly installed on the bottom surface of the horizontal rods 32. The vertical plate of one L-shaped plate 311 is fixedly connected to the output end of the second cylinder 322, and the vertical plate of the other L-shaped plate 311 is fixedly connected to the output end of the first cylinder 321. In use, the two clamps 31 inside the same clamp pair are located on both sides of the packaging bag 6. When the opening mechanism opens the packaging bag 6, the first cylinder 321 and the second cylinder 322 drive the corresponding clamps 31 to move relative to each other, clamping the edges of the two sides of the opened packaging bag 6 to prevent the packaging bag 6 from falling under the weight of the small product and to ensure stability.

[0036] For further details, please refer to Figure 3 and Figure 5 As shown, the bag opening assembly includes four first suction heads 33 and two L-shaped upright plates 331. Two first suction heads 33 are mounted side-by-side on the outer side of the vertical plate of the L-shaped upright plate 331. The first suction heads 33 are connected to the air pipe via L-shaped connecting pipes. This allows the first suction heads 33 to adsorb the packaging bag 6; this part is existing technology and will not be described in detail again. The horizontal plate of the L-shaped upright plate 331 is fixedly connected to the output end of the cylinder A332. The two cylinders A332 are respectively fixedly installed on the front and rear sides of the inner top of the packaging box 1. In use, the two cylinders A332 drive the corresponding L-shaped upright plates 331 to move relative to each other, causing the corresponding first suction heads 33 to contact both sides of the packaging bag 6. After the first suction heads 33 stably adsorb the packaging bag 6, the two cylinders A332 drive the two L-shaped upright plates 331 to move backwards, thus opening the packaging bag 6, which is convenient and practical.

[0037] For further details, please refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 7As shown, the bag storage mechanism 2 further includes a material conveying slide rail 23 located between the two vertical plates 21. A material conveying slider is slidably installed on the material conveying slide rail 23. A push plate 22 is fixedly installed on the upper part of the material conveying slider. L-shaped limiting plates 211 are symmetrically arranged on the upper and lower sides of the ends of the vertical plates 21. A number of packaging bags 6 are arranged side by side and sequentially installed between the push plate 22 and the horizontal plates of the four L-shaped limiting plates 211. The L-shaped limiting plates 211 limit the packaging bags 6. More specifically, the elastic driving member includes an elastic rope 24. A U-shaped block 241 is provided at the front of the material conveying slide rail 23. A pulley 242 is rotatably installed between the two side blocks of the U-shaped block 241. One end of the elastic rope 24 is fixedly installed on the bottom surface of the material conveying slide rail 23, and the other end is fixedly connected to the material conveying slider after passing around the outside of the pulley 242. Through the restoring elastic force of the elastic rope 24, the push plate 22 is driven to press the packaging bags 6 forward, ensuring the continuous and orderly feeding of the packaging bags 6, which is convenient and practical. A first rack 212 is fixedly installed on the inner side of one side plate of the L-shaped limiting plate 211; second racks 243 are fixedly installed at the tops of the two side blocks of the U-shaped block 241. The first rack 212 and the second rack 243 are in corresponding positions; the teeth on the first rack 212 are also precisely corresponding to the teeth on the second rack 243. When the packaging bags 6 are adsorbed away, through the拨动 of the teeth on the packaging bags 6, the phenomenon that adjacent packaging bags 6 are tightly adhered to each other and are adsorbed away together is avoided, which is convenient and practical.

A number of second suction heads 541 are installed on the cross bar of the vertical frame 54. The second suction heads 541 are connected to the air pipe through an L-shaped connecting pipe; by driving a number of second suction heads 541 to move through the third air cylinder 53, the second suction heads 541 are made to adhere to the packaging bags 6 and the packaging bags 6 are removed from the end of the bag storage mechanism 2.

[0039] Further, please refer to Figure 3 and Figure 9As shown, the bag clamping assembly includes two symmetrical Z-shaped plates 55. Two vertical plates 551 are symmetrically installed on the upper right side of the horizontal transfer plate 51. The top of the vertical plates 551 is fixedly installed with the Z-shaped plates 55. The driving component C is a bidirectional cylinder 552. The two output ends of the bidirectional cylinder 552 are respectively fixedly connected to the two vertical plates 551. When the operator puts a small product into the packaging bag 6, the horizontal transfer plate 51, driven by the driving component D, moves the bag clamping assembly to the corresponding position of the opening mechanism. Then, the bidirectional cylinder 552 drives the two Z-shaped plates 55 to move relative to each other to clamp the packaging bag 6. At this time, the bag opening component and the clamping component release the packaging bag 6. The driving component D then drives the horizontal transfer plate 51 to the left to move the packaging bag 6 between the two pressure plates 41 for heat sealing by the pressure plates 41. More specifically, the drive assembly D includes a conveyor chain assembly 56 and a servo motor 561. The conveyor chain assembly 56 is installed at the bottom inside the packaging box 1. The lower rear surface of the horizontal transfer plate 51 is fixedly connected to the conveyor chain of the conveyor chain assembly 56. The front part of the horizontal transfer plate 51 is slidably installed on the transfer plate slide rail 52. The servo motor 561 drives the conveyor chain assembly 56 to reciprocate.

The output end of the fourth cylinder 42 is fixedly connected to a pressure plate 41, and another pressure plate 41 is installed at the top inside the packaging box 1. When the fourth cylinder 42 drives the pressure plate 41 to squeeze the packaging bag 6, the heat sealing strip on the inner side of the pressure plate 41 is in a heated state, thereby heat sealing the packaging bag 6. More specifically, a conveyor belt assembly 7 is provided at the bottom of the packaging box 1, and a receiving hopper 71 is provided above one end of the conveyor belt assembly 7, with the receiving hopper 71 corresponding to the position of the two pressure plates 41; a discharge port corresponding to the end of the conveyor belt assembly 7 is opened on the lower right side of the rear of the packaging box 1; a conveyor 8 for conveying the packaging bag 6 is provided on the rear side of the packaging box 1, and the conveyor belt 81 of the conveyor 8 is inclined from the lower right side of the rear of the packaging box 1 to the upper left; when the packaging bag 6 is squeezed and heat-sealed by the pressure plate 41, the drive assembly D moves the two Z-shaped plates 55 away from the bottom of the sealing mechanism; when the packaging bag 6 is heat-sealed, the fourth cylinder 42 drives the pressure plate 41 to leave the packaging bag 6, and the packaging bag 6 falls into the receiving hopper 71, and is then conveyed away by the conveyor belt assembly 7, which is convenient and practical.

[0041] Example 2:

[0042] Please see Figure 11As shown, the clamping component in Embodiment 1 can be replaced by the inner support component in this embodiment. The opening mechanism 3 also includes an inner support component for clamping the packaging bag 6 and two U-shaped inner support plates 34 with opposite openings. The angle between the side plate and the bottom plate of the U-shaped inner support plate 34 is an obtuse angle. The U-shaped inner support plate 34 is installed at the lower end of the vertical plate of the L-shaped plate 311. The end of the horizontal plate of the L-shaped plate 311 is fixedly connected to the output end of the fifth cylinder 342.

The rear end of the horizontal rod 32 is slidably installed on the horizontal rod slide rail 11 installed on the rear side inside the packaging box 1. Two sixth cylinders 343 are symmetrically installed on the top inside the packaging box 1. The output end of the sixth cylinder 343 is fixedly connected to the rear side of the horizontal rod 32. After the packaging bag 6 is opened by the bag opening component, the two fifth cylinders 342 synchronously drive the two L-shaped plates 311 to move downward, so that the two U-shaped inner support plates 34 extend into the open packaging bag 6; then the sixth cylinder 343 drives the two horizontal rods 32 to move backward, which in turn drives the two U-shaped inner support plates 34 to move backward, tightening the packaging bag 6 and preventing the packaging bag 6 from falling under the weight of the small product, thus ensuring stability.
