Composite material filling bag sealing device capable of extending sealing time

A composite material filling bag sealing device capable of extending the sealing time. The utility model is characterized in that the lower part of the rack is respectively provided with a driving shaft and a driven shaft, the driving shaft is equipped with a 73 input wheel, a driving wheel, a front wheel, a rear wheel and a power output wheel, and the driven shaft is respectively arranged with a driven wheel and a front wheel. , After the synchronous wheel, the driving wheel meshes with the driven wheel, and the moving 73 output wheel is connected with the sealing cutting device; the upper part of the upper part of the machine frame is the upper left shaft and the upper right shaft, and the front and rear synchronous wheels are respectively arranged on the upper part and the front and rear are synchronized. The wheels are connected with the front and rear synchronous wheels on the active and driven axles respectively; the front and rear chains on the left and the front and rear chains on the right are equipped with sealing strips respectively. When the motor rotates, it feeds continuously and seals continuously. The utility model greatly extends the sealing between the elbows, greatly improves the sealing quality and the working efficiency, and is particularly suitable for the sealing of the multi-layer composite material or the thick substrate filling bag.
