By adjusting the positions of the first positioning block 64 and the second positioning block 66, the pressure of the pressing roller 6 to the heating roller 5 can be adjusted, and the pressures to which the first base film and the second base film are subjected can be changed.
As shown in fig. 5 to 8, when the drum rotates in the forward direction, even though the first and second base films pass through the heating drum 5 and the pressing drum 6 to be combined, the first shaft 542 is driven to rotate in the forward direction by the first connecting gear 541, the second shaft 553 is driven to rotate in the forward direction by the second connecting gear 543, so that the first piston 544 and the second piston 555 can rotate in the forward direction, the medium in the inner cavity 527 enters the first liquid inlet chamber 525 through the second connecting hole 529, the medium in the inner cavity 527 enters the first buffer chamber 523 through the first connecting hole 528 from the first liquid outlet chamber 526, the medium in the inner cavity 527 enters the second liquid inlet chamber through the fourth connecting hole 537, the second liquid outlet chamber enters the second buffer chamber 532 through the third connecting hole, and the medium in the inner cavity 527 from the annular outer cavity 522 through the reflow hole 530.
When the first piston member 544 abuts against the first clamping member 549, the first clamping member 549 can be pushed to slide along the axial direction of the cylinder 52, so as to separate from the first blocking hole 548 and separate from the first blocking plate 545. As the first piston member 544 continues to rotate, when the first piston member 544 abuts against the first pushing inclined surface 547 of the first baffle 545, the first baffle 545 can be pushed to slide along the axial direction of the cylinder 52, so that the first piston member 544 can pass over the first baffle 545 to continue to rotate forward, when the first piston member 544 passes over the first baffle 545, the first baffle 545 is reset under the action of the first elastic member 546, and when the first clamping member 549 corresponds to the first clamping hole 548, the first clamping member 549 is clamped into the first clamping hole 548 under the action of the second elastic member 550, so that the first baffle 545 is fixed. At this time, the first liquid inlet chamber 525 is at a minimum state, and the first liquid outlet chamber 526 is at a maximum state, so that the first piston member 544 continuously rotates in the forward direction, and the heated medium in the inner chamber 527 can be continuously pumped into the annular outer chamber 522 through the first connecting hole 528 and the second connecting hole 529.
Similarly, the second piston member 555 operates in the same manner as the first piston member 544, so that the medium synchronously enters the annular outer cavity 522 from both ends of the cylinder 52, and then flows back to the inner cavity 527 through the backflow hole 530, so that the medium in the annular outer cavity 522 maintains a stable temperature, and the first base film and the second base film can be continuously heated.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
