Utility model content
The purpose of this utility model is to provide a kind of longitudinal sealing device, realizes there is the phenomenon of edge sealing sideslip in longitudinal sealing process time, and drive roll can separate fast with driven voller, to adjust in time packaging bag position.
The utility model solves the technical scheme that its technical matters adopts:
A kind of longitudinal sealing device, comprises frame, motor, drive roll, driven voller, driving gear, drive shaft bearing, imput shaft, driven gear, driven shaft, driven shaft bearing, driven axle bed, separator levers, pull bar, holddown spring, described motor is laterally fixed on frame one side, described motor shaft is connected in imput shaft, described imput shaft is rotatable to be arranged in frame, in described imput shaft, be also provided with driving gear, described imput shaft is provided with drive roll foremost, described frame lower end is provided with longitudinal guide rail, described driven axle bed by guide rails assembling in frame, between described driven axle bed and frame, be connected with holddown spring, described frame below is also hinged with separator levers, between described driven axle bed and separator levers, be connected with pull bar, on described driven axle bed, be rotatably provided with driven shaft, on described driven shaft, be provided with driven gear, described driving gear and driven gear are intermeshing, the transmitting ratio of described driving gear and driven gear is 1:1, described driven shaft is provided with driven voller foremost, the tangent setting of described drive roll and driven voller, described drive roll is identical with driven voller diameter.
Further, between described imput shaft and frame, be provided with drive shaft bearing.
Further, between described driven shaft and frame, be provided with driven shaft bearing.
Further, described separator levers one end is provided with handle.
Further, described motor is stepping motor.
Further, on described drive roll and driven voller, be all provided with heating arrangement.
Compared to the prior art the utility model, has the following advantages and effect: driven by motor imput shaft is rotated, and drive roll, driving gear are arranged in imput shaft, rotate with imput shaft.Driven gear and driving gear equal and opposite in direction, switched in opposite, therefore driven gear drives driven voller and drive roll constant speed to rotate backward, and realizes and pulls packaging bag and longitudinal sealing.Before longitudinal sealing starts, or while there is the phenomenon of edge sealing sideslip in working process, only need cw to move the handle of separator levers, separator levers drives driven axle bed to move downward along guide rail by pull bar, separates with drive roll thereby realize driven voller.When the utility model can be realized the phenomenon that occurs edge sealing sideslip in longitudinal sealing process, drive roll can separate fast with driven voller, adjusts in time fast packaging bag position.
