[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a fully automatic bag making and filling machine includes a fixed frame 1, an upper mold 2 is installed on the top of the fixed frame 1, a lower mold 3 is installed in the middle of the fixed frame 1, the position of the lower mold 3 remains unchanged, a rotating rod 4 is rotatably installed on one side of the upper mold 2, an extrusion roller 5 is rotatably installed between the bottom ends of the two rotating rods 4, a moving rod 6 is slidably installed below the upper mold 2, and a push block 7 is fixedly installed on one side of the moving rod 6, the push block 7 is arranged to contact the surface of the upper mold 2, and the push block 7 moves as the upper mold 2 descends.

[0022] like Figures 1 to 4 As shown, a hydraulic rod 8 is fixedly installed on the top of the fixed frame 1, an upper mounting plate 9 is fixedly installed on the movable end of the hydraulic rod 8, the upper mold 2 is fixedly installed below the upper mounting plate 9, a lower mounting plate 10 is fixedly installed in the middle of the fixed frame 1, and the lower mold 3 is fixedly installed in the middle of the upper surface of the lower mounting plate 10.

[0023] The hydraulic rod 8 controls the upper mounting plate 9 to descend, which drives the upper mold 2 to approach the lower mold 3. As the upper mold 2 contacts the lower mold 3, the bag roll is printed.

[0024] like Figures 1 to 4 As shown, a rotating shaft 11 is symmetrically mounted on one side of the upper mounting plate 9, the top of the rotating rod 4 is fixedly mounted on the middle of the rotating shaft 11, and a torsion spring 12 is sleeved on the outside of one end of the rotating shaft 11. One end of the torsion spring 12 is fixedly connected to one end of the rotating shaft 11, and the other end of the torsion spring 12 is fixedly connected to the upper mounting plate 9.

[0025] The hydraulic rod 8 controls the upper mounting plate 9 to descend, which will drive the upper mold 2 close to the lower mold 3. The squeezing roller 5 installed on the upper mounting plate 9 will squeeze the bag downward, which will drive the rolled bag into a tensioned state. As the upper mounting plate 9 descends and the squeezing roller 5 squeezes the bag, the rolled bag will exert a reverse force on the squeezing roller 5, which will drive the rotating rod 4 equipped with the squeezing roller 5 to rotate. At this time, the torsion spring 12 is in a torsion state, which is used to keep the rolled bag tensioned.

[0026] like Figures 1 to 4 As shown, the upper mounting plate 9 is symmetrically fixed with limit rods 13 on both sides, the movable rod 6 is slidably installed between the two limit rods 13, the two ends of the movable rod 6 are symmetrically fixed with guide rods 14, the two sides of the fixed frame 1 are symmetrically fixed with positioning frames 15, the middle part of the positioning frame 15 is provided with a guide groove 16, the guide groove 16 is inclined, and the guide rod 14 is slidably connected to the guide groove 16.

[0027] When the squeezing roller 5 squeezes the bag, the tensioned bag will generate downward pressure on the lifting roller 19, which will drive the slide rod 18 equipped with the lifting roller 19 to slide down inside the slide hole 17. At this time, the return spring 20 is in an extended state. During the descending process of the upper mold 2, the guide groove 16 will limit the guide rod 14, and will drive the moving rod 6 installed with the guide rod 14 between the two limit rods 13. The push block 7 on one side of the moving rod 6 will push and clean the plastic stuck to the upper mold 2 after the last printing.

[0028] like Figures 1 to 4 As shown, the lower mounting plate 10 is provided with sliding holes 17 at the four corners corresponding to the lower mold 3, and a sliding rod 18 is slidably installed inside the sliding hole 17. A lifting roller 19 is rotatably installed between the two sliding rods 18, and a reset spring 20 is sleeved on the outer side of the bottom end of the sliding rod 18. One end of the reset spring 20 is fixedly connected to the bottom end of the sliding rod 18, and the other end of the reset spring 20 is fixedly connected to the lower mounting plate 10.

[0029] After the hot pressing printing is completed, the reset spring 20 will drive the lifting roller 19 to squeeze and lift the bag in the printing area to prevent the bag from sticking to the lower mold 3.

[0030] like Figures 1 to 4 As shown, positioning rollers 21 are rotatably mounted on the upper surface of the lower mounting plate 10 corresponding to the two sides of the lower mold 3 .

[0031] Used to control the horizontal position of the rolled bags.

[0032] The utility model provides a fully automatic bag making and filling machine, the specific working principle of which is as follows:

[0033] When the device is in use, the rolled bag passes between the upper mold 2 and the lower mold 3, and the rolled bag is unwound through the unwinding mechanism. The upper mounting plate 9 is controlled to descend by the hydraulic rod 8 to drive the upper mold 2 close to the lower mold 3. The squeezing roller 5 installed on the upper mounting plate 9 will squeeze the bag down, which will drive the rolled bag to be in a tensioned state. As the upper mounting plate 9 descends and the squeezing roller 5 squeezes the bag, the rolled bag will have a reverse force on the squeezing roller 5, which will drive the rotating rod 4 equipped with the squeezing roller 5 to rotate. At this time, the torsion spring 12 is in a torsion state, which is used to keep the rolled bag tensioned. When the squeezing roller 5 squeezes the bag, the tensioned bag will exert force on the lifting roller 19. The downward pressure will drive the slide bar 18 equipped with the lifting roller 19 to slide down inside the slide hole 17. At this time, the return spring 20 is in a stretched state. During the descending process of the upper mold 2, the guide groove 16 will limit the guide rod 14, and will drive the moving rod 6 installed with the guide rod 14 between the two limiting rods 13. The push block 7 on one side of the moving rod 6 will push and clean the plastic stuck to the upper mold 2 after the last printing. When the upper mold 2 is close to the lower mold 3, the moving rod 6 will move out of the space between the upper mold 2 and the lower mold 3 to prevent affecting the contact between the upper mold 2 and the lower mold 3. As the upper mold 2 and the lower mold 3 contact, the printing operation will be performed on the rolled bag.

[0034] After the hot pressing printing is completed, the upper mounting plate 9 is controlled to rise by the hydraulic rod 8, which will drive the upper mold 2 away from the lower mold 3. The rotation of the rotating shaft 11 by the torsion spring 12 will drive the rotating rod 4 to rotate and reset. At the same time, the reset spring 20 will drive the lifting roller 19 to squeeze and lift the bag in the printing area to prevent the bag from sticking to the lower mold 3. As the upper mold 2 rises, the guide rod 14 is limited by the guide groove 16 and will slide inside the guide groove 16, which will drive the moving rod 6 installed with the guide rod 14 to slide in the opposite direction between the two limit rods 13 to the initial position.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
