Description

Technical Field

[0002] Vacuum packaging is widely used for granular materials such as rice and peanuts because it extends shelf life and facilitates stacking.

[0173] The secondary shaping bracket 303 is installed on the conveyor frame 313 of the conveyor 301. The opening on the secondary shaping bracket 303 is equipped with a vacuum lifting cylinder (not shown in the figure). The secondary shaping bracket 303 is installed on the conveyor frame 313 through the support columns 304 on both sides.

[0174] The top cover 300 has an opening at the bottom. The two sides of the top cover 300 are slidably connected to the secondary shaping frame 303 through the slider guide rail pair. The guide rod end of the vacuum lifting cylinder (not shown) is connected to the top cover.

[0175] The pressure plate lifting cylinder 306 is installed on the outside of the top plate of the upper cover 300, and the guide rod of the pressure plate lifting cylinder 306 passes through the top plate of the upper cover 300 and extends into the interior of the upper cover 300.

[0176] Secondary shaping pressure plate 305, such as Figure 21 As shown, the secondary shaping plate 305 is located inside the upper cover 300, and the secondary shaping plate 305 is connected to the plate lifting cylinder 306.

[0177] The packaging machine provided in this application, after the material packaging bag is filled from the receiving hopper, rotates the receiving hopper lifting motor 810 to move the receiving hopper 9 downwards, placing the material bag between the first shaping plate 603 and the second shaping plate 604 of the shaping mechanism 6, and releasing the bag clamping mechanism. At this time, the clamping jaw 512 of the clamping mechanism 5 opens and moves forward to the rear side of the material packaging under the drive of the cylinder 508. At this time, the clamping jaw 512 clamps the opening of the material bag under the drive of the clamping jaw opening and closing cylinder 513. At this time, if the packaging is a "two-sided" type packaging, the first shaping plate 603 and the second shaping plate 604 move towards each other under the drive of the opening and closing motor 632 to clamp and shape the material into a two-sided shape. At this time, the lower bearing mechanism 4 rotates 90 degrees to the left or right to rotate the shaping mechanism 6 directly below the opening vacuum mechanism 10. At this time, the opening vacuum mechanism 10 moves downwards to complete the vacuuming and pre-sealing of the material packaging. At this time, the gripper 512 of the clamping mechanism 5 opens and moves backward under the drive of the cylinder 508. Meanwhile, the stoma vacuum mechanism 10 clamps the material package and moves upward to pull the package out of the shaping mechanism 6 (at this time, the front and rear pressure plates of the shaping mechanism 6 open). Then, the lower bearing mechanism 4 rotates 90 degrees to the right or left, rotating the receiving mechanism 7 below the stoma vacuum mechanism 10. The stoma vacuum mechanism 10 places the package onto the receiving tray 709 (initially, the guide rod of the flipping cylinder 707 extends, rotating the receiving tray 709 upward; when the material package is placed into the receiving tray 709, the positioning cylinders on both sides...). (708 extends to fix the package in the middle of the receiving tray) At this time, as the lower bearing mechanism 4 rotates, the receiving mechanism 7 rotates to the position of the secondary vacuum shaping mechanism 3. At this time, the guide rod of the flipping cylinder 707 retracts, placing the material package onto the conveyor belt 312. Then, the material package is sent to the bottom of the upper cover 300. The upper cover 300 moves downward under the drive of the lifting cylinder 302 until it is completely in contact with the conveyor belt. At this time, the pressure plate 305 moves downward under the drive of the pressure plate cylinder 306 until the material package is flattened to a "two-sided" state. At this time, the secondary vacuum shaping mechanism 3 performs a secondary vacuuming inside the upper cover 300 and seals it. Then, driven by the conveyor belt 312, it moves to the left to the next station.

[0178] If the packaging is a "six-sided" type, the side molds are manually installed into the side mold installation mechanism 616 according to the different packaging. After the material packaging is placed between the first shaping plate 603, the second shaping plate 604, and the side molds, the first shaping plate 603 and the second shaping plate 604 move towards each other. At the same time, the two side mold installation mechanisms 616 move towards each other under the drive of the second cylinder 623, so that the material packaging bag forms a cube with edges. At this time, the lower bearing mechanism 4 rotates 90 degrees to the left or right to rotate the shaping mechanism 6 to be directly below the stomping vacuum mechanism 10. At this time, the stomping vacuum mechanism 10 moves downward to complete the vacuuming and sealing of the material packaging. At this time, the gripper 512 of the clamping mechanism 5 opens and moves backward under the drive of the cylinder 508. Meanwhile, the ostomy vacuum mechanism 10 clamps the material package and moves upward to pull the package out of the shaping mechanism 6 (at this time, the front and rear pressure plates and the two side mold mounting mechanisms 616 of the shaping mechanism 6 open simultaneously). Then, the lower bearing mechanism 4 rotates 90 degrees to the right or left, rotating the receiving mechanism 7 below the ostomy vacuum mechanism 10. The ostomy vacuum mechanism 10 places the package onto the receiving tray 709 (in its initial state). The guide rod of the flipping cylinder 707 extends to rotate the receiving tray 709 upward. When the material package is placed into the receiving tray 709, the positioning cylinders 708 on both sides extend to fix the package in the middle of the receiving tray. At this time, as the lower bearing mechanism 4 rotates, the receiving mechanism 7 rotates to the position of the secondary vacuum shaping mechanism 3. At this time, the guide rod of the flipping cylinder 707 retracts to place the material package onto the conveyor belt 312 (when performing six-sided vacuum, the upper cover 300 always stays on top and does not move), and is transported to the next station by the conveyor belt 312.
