Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, specifically to a tilting packaging machine. Background Technology

[0002] In the prior art, patent document CN 109878815A discloses a continuous sealing and packaging machine. This machine includes a film feeding mechanism and a lifting mechanism located below the film feeding mechanism. The lifting mechanism synchronously adjusts the height of the sealing mechanism, allowing for simultaneous film pulling and horizontal sealing, thus eliminating waiting time. A packaging method is also provided, comprising the following steps: fixing the sealing mechanism above a horizontal sealing mounting base plate; using a servo motor to drive the sealing machine up and down for sealing; placing a packaging film roll on an adjusting shaft and fixing it with a film baffle; pulling out one end of the packaging film and winding it sequentially through a tension roller and a film roller before it enters the sealing mechanism for packaging. By incorporating components such as an origin sensor, the packaging film wound on the tension roller and film roller is kept in a taut, secure state. Simultaneously, changes in the position of the swing arm cause changes in the encoder angle, facilitating detection and adjustment of the stepper motor's rotation speed.

[0003] The existing technology represented by the aforementioned packaging machine has the following defects: First, it is easy for wrinkles to form at the sealing point, which affects the appearance of the packaging bag; second, packaging machines that package small bags all adopt a vertical feeding method, resulting in small bags being suspended in the packaging bag and unevenly distributed. Summary of the Invention

[0004] The purpose of this invention is to provide a tilting packaging machine that provides dense and compact packaging while saving packaging materials.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

The length of the packaging bag can be set arbitrarily.

[0032] The longitudinal sealing device 4 is used to heat-press the two sides of the packaging film together, so that the packaging film changes from a sheet to a tube. The transverse sealing device 5 is used to heat-seal the packaging film laterally. The packaging film forming device 2 is used to form the packaging film into a square structure, with a width and height slightly larger than the small bag, to ensure that it does not jam and can slide smoothly.

[0033] The packaging film forming device 2, film stretching device 3, longitudinal sealing device 4, and transverse sealing device 5 are sequentially installed on the inclined worktable 6, which is mounted on the frame 7. This invention is specifically designed for packaging small bags, improving the equipment by changing the traditional vertical feeding method to an inclined feeding method, and changing the packaging film forming device from a circular opening to a square opening. This not only makes the small bags neatly arranged and facilitates feeding, but also makes the small bags inside the packaging bag more compact, saving packaging materials.

[0034] like Figure 4 , 5 As shown in Figure 6, specifically, the tilt angle of the tilting worktable 6 is adjustable. A fixed upright plate 9 is provided on the bottom crossbeam 8 of the frame 7.

The left film-pulling belt 15 is mounted on the left drive wheel 14 and the left driven wheel 16. The left drive wheel 14 and the left driven wheel 16 are located on two left rotating shafts 30 on the left fixed plate 17. The left fixed plate 17 is fixed to the left slider 19 via the left connecting cylinder 18. The left slider 19 is mounted on the slide rod 21. Rod 21 is mounted on support base 22, which is fixed to the inclined worktable 6. Left cylinder 20 is fixed on support base 22 and is used to drive left slider 19 to slide along slide rod 21. Left tension film belt 15 and right tension film belt 24 are parallel. Right tension film belt 24 is mounted on right drive wheel 23 and right driven wheel 25. Right drive wheel 23 and right driven wheel 25 are mounted on two right rotating shafts 31 on right fixed plate 26.

Right cylinder 29 is fixed on support base 22 and is used to drive right slider 28 to slide along slide rod 21. A left motor and a right motor are respectively installed inside the left connecting cylinder 18 and the right connecting cylinder 27. The left motor and the right motor drive the left rotating shaft 30 and the right rotating shaft 31 to rotate, respectively. The left rotating shaft 30 and the right rotating shaft 31 drive the left drive wheel 14 and the right drive wheel 23 to rotate, respectively. The left drive wheel 14 and the right drive wheel 23 drive the left film-pulling belt 15 and the right film-pulling belt 24 to move synchronously. The above-mentioned film-pulling device adopts a modular design, which is not only simple and compact in structure, but also has the function of adjusting the distance between the left and right film-pulling belts.

[0036] like Figure 7 , 8 As shown, the packaging film forming device includes a fixing frame 32, a square mold core cylinder 33, and a feeding hopper 34.
