Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil bags, in particular to an aluminum foil bag sealing machine. Background Art

[0002] Aluminum foil bags are also called pure aluminum bags. Aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. This type of product is suitable for moisture-proof, light-proof, and vacuum packaging of large-scale precision machinery and equipment, chemical raw materials, and pharmaceutical intermediates. It mostly adopts a four-layer structure and has good water-proof and oxygen-proof functions. There are no restrictions. Packaging bags of different specifications and styles can be customized. They can be made into flat bags, three-dimensional bags, accordion bags and other styles. The products must be tested by GB and ASTM standards. The products meet environmental protection requirements and meet the most stringent environmental protection standards for packaging materials in the EU and North America.

[0003] Sealing machines are mechanical equipment that seals the packages containing products. After the products are put into the packaging bags, in order to keep the products in a sealed environment, maintain product quality, and avoid product loss, the packaging bags need to be sealed with a sealing machine. Currently, sealing machines are widely used in the fields of pharmaceuticals, food, cosmetics, etc., and can achieve heat sealing of low-density polyethylene bags, aluminum foil bags, paper-plastic composite bags and other products.

[0004] The bag made of aluminum foil can be used to encapsulate the contents. The contents are put into the bag made of aluminum foil, and the opening of the bag made of aluminum foil is heated by a sealing machine so that the opening of the bag made of aluminum foil is fitted together.

[0005] In the prior art, when the existing sealing machine is in use, the operator usually inserts the package to be sealed into the upper and lower heating plates of the sealing machine, and heat-presses and seals the package bag under the conveyance of the conveyor belt. However, when the package bag is conveyed by the conveyor belt, since the package bag contains items, the items inside the package bag are easily moved during the conveyance, thereby pulling the package bag to move as a whole, causing the package bag to tilt inside the sealing machine, affecting the subsequent sealing quality of the package bag;

[0006] In addition, the sealing part of the existing sealing machine has no shielding device. If dust and dirt in the air fall on the sealing part, it may cause the conveying wheel to be stuck, and small dust can easily enter the bag, thereby affecting the quality of the tinfoil bag.

[0036] As a specific technical solution of this embodiment, the sealing limit structure 8 includes a brake box 17, and two electric push rods 18 are fixedly installed on the inner wall of the brake box 17. The movable ends of the two electric push rods 18 are respectively fixedly connected to a lower contact bar 20 and an upper contact bar 21 through a bending rod 19. The lower contact bar 20 is located directly below the upper contact bar 21, and the lower contact bar 20 and the upper contact bar 21 are both located above the conveyor belt 4.

[0037] In this embodiment, the two sets of electric push rods 18 can drive the lower contact bar 20 and the upper contact bar 21 to move toward each other, so that the lower contact bar 20 and the upper contact bar 21 can clamp the opening of the aluminum foil bag to prevent the aluminum foil bag from sliding down and expose a portion of the opening of the aluminum foil bag, thereby being used for hot pressure sealing the bag.

[0038] As a specific technical solution of this embodiment, the inner sides of the lower abutment bar 20 and the upper abutment bar 21 are both rotatably connected with abutment rollers 22, and the two groups of abutment rollers 22 are placed opposite to each other.

[0039] In this embodiment, the lower and upper contact bars 20 and 21 are provided with contact rollers 22 so that the tinfoil bag can move between the lower and upper contact bars 20 and 21 after the lower and upper contact bars 20 and 21 have completed clamping the tinfoil bag.

[0040] As a specific technical solution of this embodiment, the dustproof shielding structure 10 includes a U-shaped frame 23, the back side of the U-shaped frame 23 is fixedly connected to the front side of the sealing device 5, the inner wall of the U-shaped frame 23 is rotatably connected to a rotating shaft 24, the surface of the rotating shaft 24 is fixedly sleeved with a shielding cover 25, and the other end of the rotating shaft 24 is fixedly connected to a gear handle 26.

[0043] In the present embodiment, the gear handle 26 is used to drive the adjustment shielding cover 25 to rotate synchronously, and then the limit pin 28 is slid forward, causing the limit pin 28 to gradually move to the hinge between the rotating gear plate 27 and the U-shaped frame 23, thereby limiting the deflection of the rotating gear plate 27 and also limiting the self-rotation of the gear handle 26, so that the limiting process of the shielding cover 25 is completed.

[0044] When in use, first measure the length of the tinfoil bag, then start the tail end limit structure 9 according to the length of the tinfoil bag, so that the output shaft of the gear motor 12 will drive the rack 13 to slide horizontally, prompting the rack 13 to drive the connecting rod 15 to move synchronously, so that the other end of the connecting rod 15 drives the push bar 16 to move above the conveyor belt 4;

[0045] Then, the sealing limit structure 8 is activated according to the length of the tinfoil bag, so that the two sets of electric push rods 18 can drive the lower abutment bar 20 and the upper abutment bar 21 to move toward each other;

[0046] Then, the tinfoil bag is placed on the conveyor belt 4 and the conveyor belt 4 is started, so that the lower abutment bar 20 and the upper abutment bar 21 can clamp the opening of the aluminum foil bag, and the push bar 16 abuts against the rear end of the tinfoil bag, so that the tinfoil bag can be stably transported on the conveyor belt 4;

[0047] The opening of the aluminum foil bag is gradually sent into the sealing device 5 for sealing. After the sealing process is completed, the aluminum foil bag will eventually fall into the bag receiving groove 6;

[0048] When it is necessary to adjust the rotation angle of the shielding cover 25, first turn the gear handle 26 to prompt the gear handle 26 to drive the adjustment shielding cover 25 to rotate synchronously, and then slide the limit pin 28 forward to prompt the limit pin 28 to gradually move to the hinge between the rotating gear plate 27 and the U-shaped frame 23, thereby limiting the deflection of the rotating gear plate 27 and also limiting the self-rotation of the gear handle 26, so that the limiting process of the shielding cover 25 is completed.

[0049] In summary, the aluminum foil bag sealing machine, by setting the sealing limit structure 8 and the tail end limit structure 9, uses the electric push rod 18 in the sealing limit structure 8 to respectively drive the lower contact bar 20 and the upper contact bar 21 to clamp the opening of the aluminum foil bag, so as to prevent the aluminum foil bag from sliding down and expose a section of the opening of the aluminum foil bag, so as to be used for hot pressing and sealing the bag, and then cooperates with the gear motor 12 in the tail end limit structure 9 to drive the rack 13 to drive the push bar 16 through the connecting rod 15 to limit the end of the tin foil bag. Compared with the prior art, this method can effectively avoid the internal tin foil bag from being damaged. The movement of objects changes the overall position of the tin foil bag, which, to a certain extent, achieves the effect of improving the sealing quality of the tin foil bag; by setting up a dustproof shielding structure 10, the gear handle 26 can drive the shielding cover 25 to rotate through the rotating shaft 24, so that the shielding cover 25 can cover the closing mouth of the sealing device 5, and then cooperate with the limit pin 28 to limit the rotation state of the gear handle 26 through the rotating tooth plate 27, so as to control the rotation angle of the shielding cover 25, avoid the situation where debris enters the inside of the sealing part, thereby ensuring the quality of the tin foil bag.
