The two groups of first push rods 4 and the two groups of second push rods 5 are slidably arranged on the frame 1. The two groups of swing devices 8 are swingably connected to the corresponding first push rod 4 and the second push rod 5 respectively. The rotating device 7 is installed on the frame 1, and the rotating device 7 is drivingly connected to the rotating rod 6.

[0020] The swing device 8 comprises a first crank connecting rod 81, a second crank connecting rod 82 and a swing rod 83. The swing rod 83 is swingably connected between the first crank connecting rod 81 and the second crank connecting rod 82. The first crank connecting rod 81 is swingably connected at the end of the rotating rod 6. The first crank connecting rod 81 is swingably connected to the first pushing rod 4.

The driving wheel 71 is arranged on the output shaft of the driving device 74. The belt 73 is arranged around the driving wheel 71 and the driven wheel 72.

[0022] The driving device 74 is an electric motor.

[0023] The driving wheel 71 is driven to rotate by the output shaft of the driving device 74. Since the belt 73 is arranged around the driving wheel 71 and the driven wheel 72, when the driving wheel 71 rotates, the belt 73 and the driven wheel 72 can be driven to rotate together. Since the driven wheel 72 is fixedly connected to the rotating rod 6, the rotating rod 6 can be driven to rotate by the output shaft of the driving device 74.

The transverse sealing mechanism of the utility model can quickly and accurately realize the movement and sealing operation of the transverse sealing clamp plate through the precise mechanical transmission design. The efficient transmission characteristics of the driving device 74 (motor) make the whole sealing process more rapid, and the response speed and execution efficiency of the pneumatic system are significantly improved, thereby improving the overall production efficiency of the packaging machine. The pneumatic system needs to be continuously supplied with air during operation, and the maintenance and adjustment of the air pressure consume a large amount of energy. The utility model adopts motor driving, the power utilization rate is high, and the energy consumption is low. In addition, the maintenance cost of the mechanical transmission system is relatively low, the repair and replacement cost caused by the failure of the air pressure system is reduced, and the service life of the equipment is prolonged. Through the design of the two swing devices 8 and the crankshaft connecting rod, it is ensured that the first transverse sealing clamp plate 2 and the second transverse sealing clamp plate 3 can be uniformly stressed during the sealing process. This design effectively avoids the problems of poor sealing and packaging material warping caused by uneven stress, and improves the sealing quality and the appearance of the packaging bag. Since the mechanical transmission system is not limited by the air pressure environment, the transverse sealing mechanism of the utility model can adapt to a wider working environment and packaging material. Compared with the complex pneumatic control system, the mechanical transmission system of the utility model has a simple structure and is convenient to operate.
