[0002] At present, factories have achieved automated packaging of products, and various packaging machines are usually selected and put into the production line. The patent document with the patent application number CN201420100732.3 discloses an end-sealing mechanism of an automated side-sealing machine, which includes a cross beam, a lifting knife cylinder, an upper sealing knife, and a lower knife seat. A lifting knife cylinder and a guide shaft are arranged on the cross beam. The lower ends of the lifting knife cylinder and the guide shaft are provided with an upper sealing knife, and an air-cooled blade guard is arranged on the upper sealing knife. Moving seats are arranged at both ends of the cross beam, and a lower knife seat and a sliding guide rail are arranged on the moving seats. The sliding guide rail is fixed on the moving seat. When the upper sealing knife of the end seal moves up and down reciprocally, the action of sealing and cutting the packaging film is realized. In the actual production process of this end-sealing mechanism, the distance between the lower knife seat and the upper sealing knife cannot be adjusted and cannot be applied to products with different heights.

The cutting knife pad is located below the sealing and cutting knife, and further includes a transverse sealing lower beam. Guide columns fixedly connected thereto are arranged at both ends in the length direction of the transverse sealing lower beam. Both ends in the length direction of the transverse sealing upper beam are fixedly connected to the guide columns. A transverse sealing middle beam is arranged between the transverse sealing lower beam and the transverse sealing upper beam.

By arranging a transverse sealing driving device, the transverse sealing middle beam and the transverse sealing lower beam are driven to move in opposite directions simultaneously. While realizing the opening and closing of the sealing and cutting knife and the cutting knife pad, the dynamic adjustment of the distance between the sealing and cutting knife and the cutting knife pad when they are opened is realized. During the production process, the distance between the sealing and cutting knife and the cutting knife pad can be flexibly adjusted according to the packaging requirements of products with different heights, improving the adaptability and practicability of the equipment.

[0016] This specific embodiment is only an explanation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0017] Such as Figures 1-3 shown, a transverse sealing mechanism of a bagging machine includes a transverse sealing upper beam d1, a sealing and cutting knife d2 suspended below the transverse sealing upper beam d1, a cutting knife pad d3, and a transverse sealing lower beam d4. The cutting knife pad d3 is located below the sealing and cutting knife d2. Guide columns d5 fixedly connected thereto are provided at both ends in the length direction of the transverse sealing lower beam d4. Both ends in the length direction of the transverse sealing upper beam d1 are fixedly connected to the guide columns d5. A transverse sealing middle beam d6 is provided between the transverse sealing lower beam d4 and the transverse sealing upper beam d1. The cutting knife pad d3 is fixedly arranged above the transverse sealing middle beam d6. The guide columns d5 pass through both ends in the length direction of the transverse sealing middle beam d6 and are slidably connected thereto. A transverse sealing drive device d7 capable of simultaneously driving the two in opposite directions is provided between the transverse sealing middle beam d6 and the transverse sealing lower beam d4.

[0018] The horizontal sealing drive device d7 includes a horizontal sealing power source d71, a drive swing arm d72 arranged at the output end of the horizontal sealing power source d71 and rotatable therewith, a power seat d75, and a drive support plate d76. One end of the drive swing arm d72 is connected with an upper crank arm d73, and the other end is connected with a lower crank arm d74. The upper crank arm d73 is hinged to the horizontal sealing middle beam d6, and the lower crank arm d74 is hinged to the horizontal sealing lower beam d4. The power seat d75 includes a support bottom plate d751 located below the horizontal sealing lower beam d4. A power mounting seat d752 and a drive shaft seat d753 are provided on the support bottom plate d751. The power mounting seat d752 and the drive shaft seat d753 are respectively arranged on both sides of the horizontal sealing lower beam d4. The horizontal sealing power source d71 is mounted on the power mounting seat d752. A motor is selected. A drive main shaft d711 for outputting torque is provided on the horizontal sealing power source d71. The drive main shaft d711 passes through the drive swing arm d72 and then is connected with the drive shaft seat d753. The drive support plate d76 includes a support plate body d761 and two reinforcing vertical plates d762 vertically arranged on the support plate body d761. The horizontal sealing lower beam d4 is fixedly connected with the end face of the support plate body d761. The two reinforcing vertical plates d762 are respectively arranged at both ends of the support plate body d761 in the length direction. One side face of the reinforcing vertical plate d762 is attached to the horizontal sealing lower beam d4. A lower crank arm seat d77 is provided on the support plate body d761. The lower crank arm d74 is hinged to the lower crank arm seat d77.

[0019] When heat-sealing the packaging film, the horizontal sealing power source d71 rotates the drive main shaft d711, and the drive main shaft d711 drives the drive swing arm d72 to swing. When the drive shaft seat d753 is the front side and the power mounting seat d752 is the back side, when the drive swing arm d72 rotates counterclockwise around the drive main shaft d7, the upper crank arm d73 moves upward under the push of the drive swing arm d72. The upper crank arm d73 pushes the horizontal sealing middle beam d6 to move upward along the guide post d5. The lower crank arm d74 moves downward under the push of the drive swing arm d72. The lower crank arm d74 pushes the horizontal sealing lower beam d4 to move downward. The horizontal sealing upper beam d1 is fixedly connected with the horizontal sealing lower beam d4 through the guide post d5. Therefore, the horizontal sealing upper beam d1 also moves downward, so that the sealing cutter d2 and the cutter pad d3 are closed to heat-seal the packaging film. On the contrary, when the drive swing arm d72 rotates clockwise around the drive main shaft d711, the sealing cutter d2 and the cutter pad d3 open, and the packaging film passes through.
