The present invention discloses a rear transverse sealing ironing block mechanism and a transverse sealing device that integrates an easy-tear cutter and a hot block. The mechanism includes a rear hot block, a spring
assembly, an easy-tear cutter, a rear hot block seat, and a rear transverse sealing frame plate; a cutter head slot through hole is provided through the rear hot block; the easy-tear cutter is detachably fixed to the upper surface of the rear hot block seat along the
processing feed direction, and the cutter tooth head of the easy-tear cutter is aligned with the cutter head slot through hole; the spring
assembly is sleeved on the rear hot block seat along the
processing feed direction, and the front
screw head of the spring
assembly is connected to the spring threaded hole, so that the rear hot block moves forward and backward relative to the hot block seat as the spring assembly is compressed during
processing and pressing. The rear transverse sealing mechanism of the present application adopts an easy-tear cutter and a hot block integrated arrangement, and the easy-tear cutter does not need power and can be driven by the power of processing and transverse sealing pressing. The mechanism ensures that the easy-tear
cut position is always consistent with the sealing position and the
processing accuracy, reduces the process and parts, and reduces the cost.
