Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1 - 3 , an embodiment provided by the present invention: A folding device for the production of facial tissues, including a workbench 1. Two groups of guide rods a2 are fixedly connected to the inner wall of the workbench 1. A support frame a3 is slidably connected to the outer wall of the guide rod a2. The support frame a3 will not shift when sliding along the outer wall of the guide rod a2. A rotating shaft a4 is rotatably connected to the inner wall of the support frame a3. A winding roller 5 is detachably connected to the end of the rotating shaft a4. The facial tissue will rotate together with the rotating shaft a4 during unwinding. Two groups of support frames b6 are fixedly connected to the outer wall of the workbench 1. A traction roller 7 is rotatably connected between the two groups of support frames b6 at intervals. The facial tissue is tractioned by the traction roller 7. A support frame c8 is fixedly connected to the outer wall of the workbench 1. A rotating shaft b9 is rotatably connected to the inner wall of the support frame c8. A frame 11 is fixedly connected to the outer wall of the rotating shaft b9. A top plate 10 is detachably connected to the outer wall of the frame 11. The frame 11 makes a circular motion with the rotating shaft b9 as the center, thereby driving the angle change of the top plate 10. An adjusting plate 14 is elastically connected to the inner wall of the frame 11 through a return spring 13. One end of the return spring 13 is fixedly connected to the bottom end of the adjusting plate 14, and the other end of the return spring 13 is fixedly connected to the inner wall of the frame 11. The adjusting plate 14 can squeeze the return spring 13 and move downward. At the same time, the elastic force generated by the deformation of the return spring 13 gives the adjusting plate 14 a reverse thrust to promote its reset. A guide rod b12 is fixedly connected to the inner wall of the frame 11. The guide rod b12 ensures that the adjusting plate 14 does not shift during the downward movement. The outer wall of the guide rod b12 is slidably connected to the inner wall of the adjusting plate 14. A number of groups of card slots 15 are provided on the inner wall of the support frame c8. The outer wall of the adjusting plate 14 is engaged with the inner wall of the card slot 15. The adjusting plate 14 is engaged with the card slot 15 to fix the angle of the top plate 10. A chute 16 is provided on the inner wall of the support frame c8. The outer wall of the adjusting plate 14 is slidably connected to the inner wall of the chute 16. After the adjusting plate 14 squeezes the return spring 13 and disengages from the card slot 15, it can slide along the inner wall of the chute 16. A folding assembly is fixedly connected to the outer wall of the workbench 1. The folding assembly includes a support frame d22. The bottom end of the support frame d22 is fixedly connected to the outer wall of the workbench 1. Two groups of folding rollers 23 are rotatably connected to the inner wall of the support frame d22. The two groups of folding rollers 23 fold up the facial tissue lifted by the top plate 10 and are taken up by the subsequent winding mechanism.

[0032] Referring to Figure 1 and Figure 4, slots 20 are provided at both ends of the unwinding roller 5. The inner end of the rotating shaft a4 is inserted into the slot 20. The two sets of support frames a3 drive the rotating shaft a4 to approach each other and insert into the slot 20, so that the unwinding roller 5 can be fixed on the device. A rectangular convex structure is provided at the end of the rotating shaft a4, which catches the inner wall of the slot 20 and rotates with it. The inner wall of the workbench 1 is rotatably connected with a threaded rod 17. The end of the threaded rod 17 is fixedly connected with a knob 21. Rotating the knob 21 can drive the threaded rod 17 to rotate. Two sets of threaded sleeves 18 are threadedly connected to the outer wall of the threaded rod 17. Reverse threads are provided on the inner walls of the two sets of threaded sleeves 18, and they approach or separate from each other as the threaded rod 17 rotates. Two sets of brackets 19 are hinged to the outer walls of the two sets of threaded sleeves 18. The ends of the brackets 19 are hinged to the inner outer walls of the support frames a3. The change in the position of the threaded sleeve 18 will drive the change in the angle of the bracket 19, thereby dragging the two sets of support frames a3 to approach or separate from each other, fixing or releasing the unwinding roller 5.

[0033] Working principle: Place the unwinding roller 5 wrapped with facial tissues between the two sets of support frames a3. Rotate the knob 21 to make the threaded rod 17 rotate, so that the two sets of threaded sleeves 18 separate from each other, driving the change in the angle of the bracket 19, thereby driving the support frames a3 to approach each other along the guide rod a2, so that the inner end of the rotating shaft a4 is stuck into the slot 20 on the side wall of the unwinding roller 5, and the unwinding roller 5 is fixed on the rotating shaft a4. When the facial tissues are folded, rotate the knob 21 in the reverse direction to extract the rotating shaft a4 from the slot 20, so as to remove the unwinding roller 5. The facial tissues are conveyed to the top plate 10 through the traction roller 7 and are lifted by the top plate 10 to fold a certain amplitude, and are folded by the folding roller 23 and collected by the winding mechanism. When changing the angle of the top plate 10 according to the thickness of the facial tissues, press down the adjusting plate 14 to squeeze the return spring 13 to retract, and pull it out from the card slot 15. Then slide the adjusting plate 14 along the chute 16 to change the angle of the top plate 10. After adjustment, release the adjusting plate 14, and the return spring 13 will push the adjusting plate 14 back into the card slot 15 for fixation. The adjustment method is simple and there is no need to reinstall the top plate 10.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
