In use of the post-processing mechanism of the present embodiment, the stack of outer towels processed by the external towel stacking machine can be transported to the first transport mechanism 5, and the fourth transport mechanism 8 can be connected to external mechanisms such as a packaging machine.

The rotation of the driving roller 30 of the first conveying mechanism 5 can drive the unit belt conveying device 10 connected with the driving roller 30 of the first conveying mechanism 5 to move so as to convey the towel stack on the driving roller 30 of the first conveying mechanism 5 to the second conveying mechanism 6 due to the operation of the conveying motor 20 of the first conveying mechanism 5.

When the tissue stack enters the second conveying mechanism 6, the conveying motor 20 of the second conveying mechanism 6 can be operated, so that the unit belt conveying device 10 of the first conveying mechanism 5 drives the tissue stack thereon to move towards the turnover mechanism 3, and at the same time, the first lifting cylinder 21 of the blocking mechanism 2 is started, so that the first lifting cylinder 21 drives the first beam 22 to move downwards, i.e. the stop 23 also moves downwards. Thus, as the stack of towels is moved into contact with the stop 23, the stack of towels is stopped by the stop 23, following the transport by the second transport mechanism 6.

Then, the pressing cylinder 11 of the pressing mechanism 1 is started, the pressing cylinder 11 drives the pressing block 13 to move downwards, the pressing block 13 moves downwards to drive the guide rod 14 to move downwards, the guide rod 14 moves to be limited by the guide sleeve 15, and therefore the movement of the pressing block 13 can be limited, so that the movement accuracy of the pressing block 13 is guaranteed, and the pressing block 13 moves downwards to press the tissue stack blocked by the stop block 23, so that each tissue on the tissue stack becomes tight and is not easy to loosen or collapse.

After the pressing, the pressing cylinder 11 and the first lifting cylinder 21 are operated to reset the stop block 23 and the pressing block 13, so that the pressed tissue stack is no longer stopped, and the pressed tissue stack can be conveyed to the clamping mechanism 33 of the turnover mechanism 3 under the conveying of the second conveying mechanism 6.

At this time, the two linear driving cylinders 341 are activated, the two linear driving cylinders 341 can respectively drive the two sliding blocks 342 to move along the guide rails 343 toward the direction of approaching the tissue stack, the mounting beam 331 connected to the sliding blocks 342 follows up, and the clamping blocks 332 disposed on the mounting beam 331 also follow up, so that the two clamping blocks 332 can clamp the tissue stack from top to bottom, i.e., the two clamping mechanisms 33 effectively fix the tissue stack, and the tissue stack is slightly lifted and separated from the contact with the second conveying mechanism 6.

Then the turning motor 31 is started, the turning motor 31 drives the rotating shaft 35 to rotate, the rotating disc 32 arranged on the rotating shaft 35 also rotates, the rotating disc 32 rotates 180 degrees, the tissue stack fixed by the clamping mechanism 33 also rotates 180 degrees, and therefore the turning of the tissue stack is realized, and the part which is positioned at the bottom of the tissue stack and is half-folded is changed to be positioned at the top of the tissue stack.

After the turning is finished, the linear driving cylinder 341 is started again to drive the two sliding blocks 342 to move along the guiding rail 343 in the direction away from the tissue stack, so that the mounting beam 231 connected with the sliding blocks 342 follows up, the clamping blocks 232 arranged on the mounting beam 331 also follow up, and thus the tissue stack is no longer clamped by the two clamping mechanisms 33, and meanwhile, the tissue stack is no longer lifted up, and the tissue stack can extend into the unit belt conveying device 10 of the third conveying mechanism 7 of the turning mechanism 3 to contact.

Thereafter, the stack of tissues can be transported out of the turnover mechanism 3 by the third transport mechanism 7, and specifically, the transport motor 20 of the third transport mechanism 7 can be operated to rotate the drive roller 30 of the third transport mechanism 7, and the rotation of the drive roller 30 of the third transport mechanism 7 can drive the unit belt transport device 10 connected thereto to move, so as to transport the stack of tissues thereon.

When the stack of tissues conveyed by the third conveying mechanism 7 passes under the pushing mechanism 4 and is located at the end point of the third conveying mechanism 7 and needs to be conveyed to the fourth conveying mechanism 8, at this time, the second lifting cylinder 41 of the pushing mechanism 4 can be started, the second lifting cylinder 41 can drive the pushing cylinder 42 to move downwards, the pushing cylinder 42 can be started so as to enable the second cross beam 43 to move transversely, the pushing block 44 connected to the second cross beam 43 can push the stack of tissues on the third conveying mechanism 7 to the fourth conveying mechanism 8, then the stack of tissues is conveyed to external mechanisms such as a packaging machine for packaging and the like by virtue of the conveying of the fourth conveying mechanism 8, and after the pushing is finished, the second lifting cylinder 41 and the pushing cylinder 42 can work so as to reset the pushing block 44. Due to the large contact area of the pushing block 44 and the tissue stack, the pushing block is adopted for pushing out, so that the tissue stack can be completely and effectively fed into the fourth conveying mechanism 8 from the third conveying mechanism 7, and the feeding time of the tissue stack can be better controlled to meet processing requirements of different packages and the like.

In this embodiment, because the independent four-section conveying mechanism is adopted, and the pressing mechanism 1, the turnover mechanism 3 and the pushing mechanism 4 are not arranged on the same conveying mechanism, and can conveniently and simultaneously carry out pressing, turnover or pushing treatment on different tissue stacks, new tissue stack conveying is not needed to be carried out after all treatment is finished by the same tissue stack, so that the working efficiency is improved, the conveying speed of the tissue stacks after conveying and processing by the tissue stacking machine and the processing speed of subsequent packaging machines and the like can be better matched, the special structure can be conveniently maintained, and the market competitiveness is strong.

What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
