[0013] The embodiment of the application provides a longitudinal sealing mechanism for a packaging machine, which solves the technical problem that the longitudinal sealing mechanism for the packaging machine in the prior art is mostly sealed by pneumatic, and the sealing effect of the packaging material is affected when the air pressure is unstable.

[0014] The technical scheme in the embodiment of the application is to solve the above problems, and the general idea is as follows:

[0015] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and specific embodiments.

[0016] A longitudinal sealing mechanism for a packaging machine, such as Figure 1 and Figure 2As shown, it comprises a rack 1, a longitudinal sealing assembly 2 for packaging wrapping paper, a rotating rod 3 rotatably connected to the rack 1, swing rods 4 arranged at both ends of the rotating rod 3, a rotating device 5 for driving the rotating rod 3 to rotate, and push rods 6 for driving the longitudinal sealing assembly 2 to move back and forth. The longitudinal sealing assembly 2 is slidingly connected to the rack 1. The longitudinal sealing assembly 2 is provided with a push rod 6 at each end. The rotating rod 3 is provided with a swing rod 4 at each end. The two sets of swing rods 4 are swingably connected to the corresponding push rods 6, respectively. The rotating device 5 is installed on the rack 1, and the rotating device 5 is drivingly connected to the rotating rod 3.

[0017] The rotating device 5 comprises a driving wheel 51, a driven wheel 52 arranged around the rotating rod 3, a belt 53 for driving the driven wheel 52 to rotate, and a driving device 54 installed on the rack 1. The belt 53 is arranged around the driving wheel 51 and the driven wheel 52. The driving wheel 51 is arranged on the output shaft of the driving device 54.

[0018] The driving device 54 is a motor.

[0019] The driving wheel 51 is driven by the output shaft of the driving device 54 in the rotating device 5, which in turn drives the belt 53 and the driven wheel 52 to rotate together. Since the driven wheel 52 is fixedly connected to the rotating rod 3, the rotating rod 3 is driven to rotate. Therefore, by reversing the output shaft of the driving device 54, the rotating rod 3 can be driven to rotate forward and backward. Since the rotating rod 3 is provided with a swing rod 4 at each end, and the two sets of swing rods 4 are swingably connected to the corresponding push rods 6, respectively, the push rods 6 can be moved back and forth by driving the two sets of swing rods 4 to swing back and forth by rotating the rotating rod 3 forward and backward. In turn, the longitudinal sealing assembly 2 can slide back and forth along the rack 1, thereby achieving the packaging of the wrapping paper.

[0020] Due to the adoption of the rack 1, the longitudinal sealing assembly 2, the rotating rod 3, the swing rod 4, the rotating device 5, and the push rod 6, by adopting mechanical transmission, the rotating device 5 (including the driving wheel 51, the driven wheel 52, the belt 53, and the driving device 54) drives the rotating rod 3 to rotate forward and backward, thereby driving the swing rod 4 and the push rod 6 to move the longitudinal sealing assembly 2 back and forth, avoiding the influence of air pressure fluctuation on the sealing effect, and significantly improving the stability and reliability of the sealing. By motor driving, the transmission process is simple and efficient, reducing the time delay of gas compression and transmission in the pneumatic system, thereby improving the sealing speed and overall working efficiency. The motor driving has fast response speed, which can quickly realize the positioning and sealing action of the longitudinal sealing assembly 2, meeting the needs of high-speed packaging production line. The utility model adopts mechanical transmission, which has simple structure, long service life of parts, reduces maintenance frequency and cost, and improves the overall economy of the equipment. The mechanical transmission system is driven by the motor, which is simple to operate and easy to realize automatic control. Through a simple electrical control system, the rotating rod 3 can be accurately controlled, thereby accurately controlling the sealing process, improving the convenience of operation and production efficiency.
