DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Embodiment 1: refer to Figures 1-5 A kind of edge sealing device, its specific implementation is as follows:

[0027] The device includes a work frame 1, two first guide plates 2 are symmetrically fixedly installed on the top of the work frame 1, for supporting and guiding the conveying of packaging bag blank.In the top center of the work frame 1, a mounting frame 3 is fixedly installed, and slide holes are formed in the inner walls of the two sides of the mounting frame 3, to provide sliding tracks for subsequent transmission assemblies.

[0028] On the top of the workbench 1, below the mounting frame 3, a base plate 4 is fixedly installed. A set of transmission assemblies are connected to the base plate 4, which are used to drive the cutting and hot pressing parts to move. Specifically, the transmission assemblies include two second guide plates 5, which are fixedly installed on both sides of the base plate 4. The top of each second guide plate 5 is fixedly installed with a limiting rod 7, and the two limiting rods 7 are commonly sleeved with a moving plate 8, which ensures that the moving plate 8 can stably move in the vertical direction.

[0029] On the bottom of the moving plate 8, a first electric heating plate 6 and a cutter 10 are fixedly installed. At the same time, the top of the base plate 4 is fixedly embedded with a second electric heating plate 9, and the first electric heating plate 6 and the second electric heating plate 9 are opposite in the vertical direction, which is used for heat sealing of the cut packaging bag blank.

[0030] On both sides of the transmission assemblies, i.e. on both sides of the moving plate 8, two connecting plates 11 are fixedly installed. The two connecting plates 11 respectively penetrate the corresponding slide holes and extend to the outside of the mounting frame 3, and are in sliding connection with the inner wall of the slide hole. In this way, when the transmission assemblies move, the connecting plates 11 will move longitudinally along the slide hole.

[0031] On the top of the workbench 1, a set of conveying mechanisms are also installed, which are used to convey the packaging bag blanks and drive the transmission assemblies to move. The conveying mechanism includes a conveying roller 16 rotatably connected to the top of the workbench 1, and a drive motor 17 fixedly installed on one side of the top of the workbench 1. The output shaft of the drive motor 17 is fixedly connected with one end of the conveying roller 16, and when the drive motor 17 is started, it will drive the conveying roller 16 to rotate.

[0032] Two drive assemblies are also connected through the inner walls of the two sides of the mounting frame 3, and the two drive assemblies are respectively connected with the conveying roller 16 and the two connecting plates 11. Specifically, each drive assembly includes a support shaft 12 which penetrates one side of the inner wall of the mounting frame 3 and is rotatably connected with one side of the inner wall of the mounting frame 3. The end of the support shaft 12 located outside the mounting frame 3 is fixedly installed with a transmission wheel 13, and the transmission wheel 13 is fixedly installed with a connecting shaft 21 at the eccentric position on one side, and the connecting shaft 21 is rotatably connected with a connecting rod 14. The top of the connecting plate 11 is fixedly installed with a sleeve ring 15 located outside the mounting frame 3, and the connecting rod 14 penetrates the sleeve ring 15 and is in sliding connection with the sleeve ring 15.

[0033] In addition, each drive assembly further comprises two synchronous wheels 19, which are respectively fixedly sleeved on one end of the support shaft 12 located in the mounting frame 3 and the conveying roller 16. A same synchronous belt 20 is drivingly sleeved on the two synchronous wheels 19. When the conveying roller 16 rotates, the corresponding support shaft 12 is driven to rotate under the driving action of the synchronous wheels 19 and the synchronous belt 20. The rotation of the support shaft 12 drives the transmission wheel 13 to rotate, and further drives the connecting rod 14 to perform annular motion. Under the sliding cooperation with the sleeve ring 15, the annular motion of the connecting rod 14 is converted into the longitudinal reciprocating motion of the connecting plate 11, so as to drive the moving plate 8, the first electric heating plate 6 and the cutter 10 to perform longitudinal reciprocating motion.

[0034] The application can be used in the technical field of packaging bag production, and can also be used in other fields applicable to the application.

[0035] Embodiment 2: Reference Figure 1 and Figure 5 On the basis of Embodiment 1, a packaging bag hot-pressing edge sealing device is applied to the technical field of packaging bag production. In order to maintain stable conveying of the packaging bag blank, a bevel guide plate 18 located on one side of the base plate 4 is further fixedly installed on the top of the workbench 1, and one side of the bevel guide plate 18 is fixedly connected with one side of the base plate 4. A supporting roller 24 is rollingly embedded on the bevel guide plate 18, which cooperates with the conveying roller 16 to rollingly support the packaging bag blank.

[0036] Finally, a supporting frame 22 is further fixedly installed on one side of the workbench 1, and a belt conveyor 23 is installed on the top of the supporting frame 22. After the packaging bag is cut and hot-sealed, it will fall on the belt conveyor 23 for subsequent transfer work.
