Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figures 1 to 10As shown, this embodiment provides a manual bagging and sealing machine, comprising: a bag storage mechanism 2, an opening mechanism 3, a bag sealing mechanism 4, and a reciprocating transfer mechanism, all sequentially mounted side by side within a packaging box 1. In this embodiment, the bag storage mechanism 2, opening mechanism 3, and bag sealing mechanism 4 are arranged sequentially from left to right, with the reciprocating transfer mechanism located at the bottom front of the packaging box 1. The bag storage mechanism 2 includes a bag conveying channel formed by two parallel vertical plates 21, and a push plate 22 located within the bag conveying channel. Driven by an elastic drive member, the push plate 22 pushes a plurality of packaging bags 6 sequentially to the end of the bag conveying channel for subsequent collection and transfer by a bag removal assembly. The opening mechanism includes two symmetrically arranged bag opening assemblies. Driven by a drive assembly A, the two bag opening assemblies grasp the sides of the packaging bag 6 and move back and forth to open the bag 6. The opened bag 6 allows the operator to place small products to be packaged into the bag 6. The bag sealing mechanism 4 includes two opposing pressure plates 41, each with a heat-sealing strip inside for heat-sealing the bag 6. Driven by drive assembly B, the two pressure plates 41 squeeze the sides of the upper end of the bag 6, sealing the bag 6 and the upper opening of the bag 6 for convenient packaging. The reciprocating transfer mechanism includes a bag retrieval assembly and a bag clamping assembly mounted on each end of a horizontal transfer plate 51. The bag retrieval assembly draws the bag 6 from the end of the bag transport channel, while the bag clamping assembly, driven by drive assembly C, clamps the bag 6. Driven by drive assembly D, the horizontal transfer plate 51 reciprocates between the bag storage mechanism 2, the opening mechanism, and the bag sealing mechanism 4.

[0034] In this embodiment, gradual bag feeding is achieved through the bag storage mechanism 2, the bag taking assembly sucks away the packaging bag 6 at the end of the bag storage mechanism 2, the horizontal transfer plate 51 transfers the bag taking assembly to the opening mechanism, and the two bag opening assemblies move back and forth to open the packaging bag 6; when the operator puts small products into the packaging bag 6, the horizontal transfer plate 51 moves to the right to drive the bag clamping assembly to clamp the packaging bag 6, and then the horizontal transfer plate 51 moves to the right to transfer the packaging bag 6 to the bag sealing mechanism 4, and the two pressing plates 41 squeeze the two sides of the packaging bag 6, so that the packaging bag 6 is heat-sealed, realizing integrated automatic packaging, which is convenient and efficient.

[0035] For further information, see 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 pairs of clamps, and the two clamps 31 in the clamp pair are respectively mounted on the side surfaces of the horizontal plates of two parallel L-shaped plates 311. Two parallel horizontal rods 32 are mounted at the center of the inner top of the packaging box 1. The opening mechanism 3 is mounted on the two horizontal rods 32. A first cylinder 321 is fixedly mounted on the outer side of the horizontal rods 32, and a second cylinder 322 is fixedly mounted on the lower 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. When in use, the two clamps 31 in the same clamp pair are respectively 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 respectively drive the corresponding clamps 31 to move relative to each other, clamping the edges of the opened packaging bag 6 to prevent the packaging bag 6 from falling under the action of gravity of small products and ensure stability.

[0036] For further information, see Figure 3 and Figure 5 As shown, the bag opening assembly includes four first suction heads 33 and two L-shaped vertical plates 331. Two first suction heads 33 are installed side by side on the outer side of the vertical plate of the L-shaped vertical plate 331.

This part is the existing technology and will not be described in detail again. The horizontal plate of the L-shaped vertical 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; when in use, the two cylinders A332 drive the corresponding L-shaped vertical plates 331 to move relative to each other, so that the corresponding first suction heads 33 contact the two sides of the packaging bag 6. After the first suction heads 33 stably absorb the packaging bag 6, the two cylinders A332 drive the two L-shaped vertical plates 331 to move backwards, thereby opening the packaging bag 6, which is convenient and practical.

[0037] For further information, see Figure 3 、 Figure 4 、 Figure 6 as well as Figure 7As shown, the bag storage mechanism 2 also includes a feed rail 23 located between two vertical plates 21.

One end of the elastic rope 24 is fixedly mounted on the lower bottom surface of the feed rail 23, and the other end passes around the outside of the pulley 242 and is fixedly connected to the feed slider. The return force of the elastic rope 24 drives the push plate 22 to squeeze the packaging bags 6 forward, ensuring 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; a second rack 243 is fixedly installed on the top of the two side blocks of the U-shaped block 241, and the positions of the first rack 212 and the second rack 243 correspond to each other; the teeth on the first rack 212 and the teeth on the second rack 243 also correspond precisely.

At this time, the bag opening assembly and the clamping assembly release the packaging bag 6; the driving assembly D then drives the horizontal transfer plate 51 to the left to transfer the packaging bag 6 to between the two pressing plates 41 to wait for the pressing plates 41 to be heat-sealed. More specifically, the drive component D includes a conveyor chain component 56 and a servo motor 561. The conveyor chain component 56 is installed at the bottom of the packaging box 1.
