Description

Technical Field

[0001] This invention belongs to the field of packaging machine technology, and specifically relates to a bag packaging machine for powdered materials. Background Technology

[0002] In recent years, packaging machinery has played an increasingly important role in my country's packaging industry and is now ubiquitous in people's lives. The development of packaging machinery is moving towards higher speed, higher efficiency, higher quality, superior and more reliable performance, and easier operation, continuously improving the advantages of packaging machines to meet the needs of various consumers in the packaging market.

[0003] Packaging machines specifically designed for packaging powdery materials have emerged as a result.

[0004] However, when existing powder packaging machines package powder materials, the large amount of material put into the packaging bag at one time causes the "backlash" of the powder material, resulting in too much dust being raised, which affects the sealing of the packaging bag.

[0005] Based on the above problems, this application proposes a powder material bag packaging machine, which uses a rotatable turntable, multiple feeding holes with valves, and brushes to enable the powder material to be fed into the packaging bag in small amounts and multiple times, thereby reducing the dust raised by the "backlash" phenomenon and thus reducing the impact of dust on the sealing of the packaging bag.

[0149] The upper part of the scraper assembly 33 is provided with a strip hole 332 for adjusting the installation height of the scraper assembly 33, and a bolt 333 is installed in the strip hole 332 to connect the scraper assembly 33 to the bracket 43.

[0150] A bagging machine for powdered materials, the specific implementation of which is as follows:

[0151] like Figure 11-12 As shown, in use, the tubular packaging paper 01 is placed on the packaging paper roller 41. The end of the packaging paper passes over the lower part of the fourth roller 424 from the rear end of the fourth roller 424, and then passes over the upper part of the third roller 423, the lower part of the second roller 422, and the upper part of the first roller 421 in sequence before passing downward through the elephant trunk forming device 5 to form the shape of a packaging bag. After passing through the elephant trunk forming device 5, the longitudinal edge of the packaging bag is conveyed downward between the two heating rings 601 and the two transmission wheels 945, and heat-sealing is achieved when passing between the two heating rings 601. After longitudinal sealing, the packaging bag is conveyed downward to the transverse sealing and cutting mechanism 7 to achieve transverse sealing and cutting.

[0152] During the downward conveying of the packaging bag, the powdery material in the hopper 21 enters the rotary table 31. As the first bevel gear 931 drives the rotary table 31 to rotate, the scraper 331 scrapes the material into the discharge hole 311. When one of the discharge holes 311 on the rotary table 31 rotates to the discharge port 322, the valve 312 at the bottom of the discharge hole 311 opens due to the lack of support from the brush 321. This allows the material to enter the longitudinally sealed packaging bag along the discharge port 322, the hose 8, and the elephant trunk forming device 5. The rotatable rotary table 31, multiple discharge holes 311 with valves 312, and brushes 321 enable the powdery material to be added to the packaging bag in small amounts and multiple times, thereby reducing the dust raised by the "backlash" phenomenon and thus reducing the impact of dust on the sealing of the packaging bag.

[0153] After the packaging bag containing powdered material arrives at the horizontal sealing and cutting mechanism 7, the horizontal sealing cylinder 751 controls the movable horizontal sealer 75 to slide along the guide shaft 73 and approach the fixed horizontal sealer 74 to achieve heat-sealing of the packaging bag. At the same time, the cam 72 rotates and pushes the cutter base 77 towards the fixed horizontal sealer 74 through the roller 79, so that the cutter 771 passes through the fixed horizontal sealer 74 to cut the package after horizontal sealing. The cut packaging bag falls from the cutting discharge hole 710 to the subsequent conveying mechanism for transmission and storage.

[0154] The drive mechanism 9 and the unfolding drive motor 4210 operate continuously, thereby realizing the continuous operation of bagging powdered materials.

[0155] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, they are not intended to limit the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the protection scope of the present invention.
