The strip packing machine can pack single-row strip bags once, can also produce multi-row strip bags once, and multi-row strip packing machine is suitable for the production of small strip bags, and multi-row strip packing machine often has inconsistent stress of each strip bag, so that a plurality of strip bags are stressed too much and are pulled to deform, and a plurality of strip bags are stressed too little and can not be completely pulled to form a film and transversely sealed, the sealing performance of the strip bags is poor, the strip bags are not cut completely, various problems such as adhesion exist, the number of columns of the multi-row strip bags is limited, and the production efficiency is influenced. The existing single-row or multi-row strip packing machine is characterized in that a longitudinal sealing mechanism and a cutter mechanism are generally fixed, namely, the longitudinal sealing mechanism and the cutter mechanism are required to be stopped when strip packing is longitudinally sealed and cut, a transverse sealing mechanism is generally arranged, only one transverse sealing mechanism is used for drawing a film and transversely sealing, and when the transverse sealing mechanism ascends and returns, the strip packing is basically in a static state due to lack of downward moving power, so that the production speed of the strip packing is influenced, but the single transverse sealing mechanism only can carry out one transverse sealing, and the sealing property of the strip packing is difficult to ensure. Meanwhile, the film feeding mechanism often has the problems that the tension of the packaging film is difficult to control, the packaging film is tight when in loosening, the accuracy of the length of the strip bag is difficult to guarantee, and the quality of a final product is affected, and the film feeding mechanism also has the phenomenon that the part of the packaging film at the tail end is wasted, the packaging film cannot be fed, the full utilization is not realized, and the packaging film is wasted.

With the adoption of the double transverse sealing mechanism, as shown in fig. 28, the double transverse sealing method comprises the following steps:

S1, a second mounting frame 62 of the first transverse sealing module moves downwards under the driving of a lifting driving module 61 to drive a front heat sealing module and a rear heat sealing module to move downwards, after the front heat sealing block 65 and the rear heat sealing block 67 on the first transverse sealing module are mutually close to each other under the driving of the transverse sealing driving module 63 to clamp a first strip package, the strip package is pulled downwards for a length L1, meanwhile, the first strip package is subjected to first transverse sealing, namely, the first transverse sealing is synchronously carried out in the process of downward bracing of the strip package, the heat sealing time is matched with the distance and the speed of the bracing package, and meanwhile, the second mounting frame 62 of the second transverse sealing module moves upwards under the driving of the lifting driving module 61 to a distance L2 and then stops moving upwards.

S2, the second mounting frame 62 of the second transverse sealing module moves downwards under the drive of the lifting driving module 61, the front heat sealing block 65 and the rear heat sealing block 67 on the second transverse sealing module are driven by the transverse sealing driving module 63 to be close to each other, after the N clamping strip is clamped, the first transverse sealing module loosens the first strip (namely, the front heat sealing block 65 and the rear heat sealing block 67 are driven by the transverse sealing driving module 63 to be far away from each other), the first transverse sealing module starts to ascend and return, in the process, the second transverse sealing module pulls the strip downwards for a length L2, and simultaneously carries out the second transverse sealing at the position of the first transverse sealing of the N strip, namely, the second transverse sealing is synchronously carried out in the process of the downward strip, the heat sealing time is matched with the distance and the speed of the strip sealing, when the first transverse sealing module clamps the next strip (namely, the next strip to be sealed) and then ascends, the second transverse sealing module loosens the N strip (namely, the two strips to be sealed) and the two strips are cut at the position of the two opposite sides, namely, the two strips are cut at the position of the two opposite sides, and the two strips are cut. At this time, the first packet only completes the first transverse sealing, and the second transverse sealing module subsequently carries out the second transverse sealing on the first packet.

In the above steps, the first transverse sealing module and the second transverse sealing module have the same actions, and all the four steps of downward synchronization, transverse sealing clamping (strip clamping), downward film pulling (or downward strip clamping), transverse sealing opening (strip loosening) and quick upward return are needed to finish the actions of one cycle, the two transverse sealing are mutually matched, when one transverse sealing moves downwards, the other transverse sealing returns upwards, but after one transverse sealing clamping strip clamping, the strip is loosened by the other transverse sealing, so that the fixed strip clamping by the transverse sealing module can be ensured, the strip cannot shake, and the transverse sealing position is accurate.

The sum of the length L1 of the strip bag pulled by the first transverse sealing module and the length L2 of the strip bag pulled by the second transverse sealing module is equal to the length L of one strip bag, and the lengths L1 and L2 can be determined according to the time of two heat sealing processes and can be the same or different. The speed of the downward movement of the first transverse sealing module is equal to the speed of the downward movement of the second transverse sealing module, so that when the two transverse sealing modules are connected, the two transverse sealing modules move downwards, the synchronization of the two downward moving processes can be ensured, and the strip coating can not be pulled due to inconsistent speeds. The upward return speed of the two transverse sealing modules can be faster than the downward movement speed, and the quick return can be realized. In this embodiment, the four steps of the first transverse sealing module are respectively T1, T2, T3, and T4, the three steps of downward synchronization and transverse sealing clamping, downward film pulling, and transverse sealing opening are all performed in the downward synchronization process, the downward synchronization time is t3=t1+t2+t3, the upward return time is T4, the duration time of one cycle of the first transverse sealing module is t1=t3+t4=t1+t2+t3+t4, and the four steps of the first transverse sealing module are respectively T5, T6, T7, and T8, the downward synchronization time is t4=t5+t6+t7, the upward return time is T8, and the duration time of one cycle of the first transverse sealing module is t2=t4+t5+t6+t8. As one of the embodiments, t1=t5, t2=t6, t3=t7, t4=t8, t4= the process of the method is carried out at T8. Of course, the duration of each step of the two transverse sealing modules can be set according to the requirement.

In this embodiment, 1<N is less than or equal to 10, the nth packet is a second packet, a third packet, a fourth packet, a fifth packet, a sixth packet, a seventh packet, an eighth packet, a ninth packet or a tenth packet below the first packet, that is, the packets clamped by the second transverse sealing module are other packets below the first transverse sealing module, the first transverse sealing module and the second transverse sealing module are heat sealed in a transverse sealing period, and are not transverse sealing positions of the same packet, a plurality of packets are spaced in the middle, and the number of the packets at specific intervals is determined according to the length of the packets and the size of the transverse sealing module.
