The lower surface of the pressure base 25 is provided with a plurality of pressure base fixing ports 35, the lower surface of the pressure conversion transmission mechanism 24 is provided with a plurality of pressure conversion transmission mechanism pressure base connecting ports 42, the pressure base 25 is tightly connected with the pressure conversion transmission mechanism pressure base connecting port 42 of the pressure conversion transmission mechanism 24 through the pressure base fixing port 35 at the bottom thereof, a plurality of lower cover plate connecting ports 43 are provided around the lower cover plate mechanical connecting port 10, a plurality of pressure conversion transmission mechanism fixing ports 36 are provided around the pressure conversion transmission mechanism 24, a plurality of pleating mechanism sleeve fixing holes 28 are provided around the pleating mechanism sleeve 23, a plurality of annular cutting cylinder fixing holes 34 are provided around the annular cutting cylinder 13, the lower cover plate connecting ports 43, the pressure conversion transmission mechanism fixing ports 36, the pleating mechanism sleeve fixing holes 28, and the annular cutting cylinder fixing holes 34 are connected one by one and the number of pore sizes is consistent, and the upper fixed connecting cylinder 11 is connected to the mold top plate 5 through the upper fixed connecting cylinder fixing port 30.

[0038] Preferably, in order to fully convert the driving effect of external pressure, the lower surfaces of the pressure support rod 20 and the upper pressure contact 27 respectively adopt a cylindrical structure support body of a certain size equal to the inner diameter of the pressure support rod connecting port 39 and the upper pressure contact connecting port 40, and the surface of the support body is covered with a colloid to increase the sealing performance.

[0039] Preferably, in order to facilitate the realization of the pleating function, the pleating function is realized by mechanical pleating grooves, and the upper surface of the lower pleating mechanism 21 of the rolled cup is provided with a pleating convex surface 32, and the lower surface of the upper pleating mechanism 22 of the rolled cup is provided with a pleating concave surface 33.

[0040] Preferably, in order to achieve the edge sealing function, the pleated paper cup is mechanically edge sealed. The upper pressure transmission cylinder 17 is in contact with the edge sealing cylinder 16, and the edge sealing cylinder 16 and the upper pressure transmission cylinder 17 are located at the top of the pressure conversion transmission mechanism 24 and supported by the pressure conversion transmission mechanism 24.

[0041] Specifically, when the present invention is used, the holes with the same size and number at the upper fixed connection tube connection port 29, the pleating limit tube penetration hole, and the pleating mechanism connection port 41 on the roll cup are fixedly connected; the upper fixed connection tube 11 is fixedly connected to the mold top plate 5 at the upper fixed connection tube fixing port 30; the holes with the same size and number at the pressure base fixing port 35, the pressure conversion transmission mechanism fixing port 36, the pleating mechanism sleeve fixing hole 28, and the annular cutting tube fixing hole 34 are fixedly connected. Thus, the upper moving operation end and the lower moving operation end of the fixing device are fixed.

[0042] By means of a machining device, the upper cover plate 3 of the present invention is fixed to the mold top plate 5 and the lower cover plate 9 respectively and connected to other external pressure control valves through the lower pressure inlet 26, and the upper surface of the lower pressure contact 18 is connected to other external mechanical telescopic structures.

[0043] Under the action of the mechanical processing device, the upper movable operating end and the lower movable operating end move in opposite directions to each other, and the cardboard and other materials to be processed are placed on the upper surface of the annular cutting cylinder 13; then the upper movable operating end and the lower movable operating end move in the same direction to each other, and under the action of the annular cutting cylinder 13, the paper sheet on the annular cutting cylinder 13 is cut into a standard circle by ring pressing to prepare for further pleating and curling.

[0044] The upper moving operation end and the lower moving operation end continue to move in the same direction. Under the action of other external pressure control valves, a large pressure is introduced into the pressure conversion transmission mechanism 24 through the lower pressure inlet 26. Under the action of pressure, the pressure balance flow channel 38 is evenly distributed.

[0045] The pressure support rod 20 and the upper pressure contact 27 located in the pressure support rod connection port 39 and the upper pressure contact connection port 40 are driven to move upward respectively, and the pressure support rod 20 supports the upper pleating mechanism 22 of the roll-top cup to move upward first; at the same time, under the action of the external mechanical telescopic structure, the lower pressure contact 18 is driven to press and move, so that the lower pressure contact 18 indirectly presses downward to drive the lower pressure transmission cylinder 15 to press and move downward, and then the lower pleating mechanism 21 of the roll-top cup and the upper pleating mechanism 22 of the roll-top cup are contacted to pleat the paper sheet. The pleating function forms wrinkles of a certain shape on the surface of the paper sheet. The roll-top cup pressing mechanism 14 is connected to the pressing contact 27 through the pressing transmission cylinder 17. Driven by the pressing contact 27, the paper sheet is gradually stretched to form a truncated cone shape, i.e., a cup-shaped container structure, and the paper sheet located in the lower pleating mechanism 21 of the roll-top cup and the upper pleating mechanism 22 of the roll-top cup is stretched. The pleated paper sheet is compressed and reinforced and moved to the upper surface of the roll-top cup pressing mechanism 14. When the upper surface of the roll-top cup pressing mechanism 14 and the lower surface of the roll-top cup pressing mechanism 19 pass through the paper sheet gap, the paper sheet is compressed and reinforced. When the paper cup is in contact, the pleating of the paper cup is completed. Subsequently, under the interlaced action of the lower pressure transfer cylinder 15, the pleating limiting cylinder 12, the edge curling and sealing cylinder 16, and the upper pressure transfer cylinder 17, the pleating area has basically entered the upper surface of the roll-top cup upper pressure mechanism 14 and the lower surface of the roll-top cup lower pressure mechanism 19, and only a small part of the edge is located at the lower part of the lower pressure transfer cylinder 15 and the pleating limiting cylinder 12 and the upper part of the edge curling and sealing cylinder 16 and the upper pressure transfer cylinder 17. Since the upper pressure contact 27 continues to rise and drives the upper pressure transfer cylinder 17 to move, the upper pressure contact 27 is The pressure transfer cylinder 17 drives the curling and edge sealing cylinder 16 to continue to move upward. Due to the height difference between the curling and edge sealing cylinder 16 and the upper surface of the upper pressure transfer cylinder 17, the curling and edge sealing cylinder 16 raises the height around the paper sheet and is higher than the upper pressure transfer cylinder 17, and forms a small section of curling in the pores. Under the downward pressure cooperation of the lower pressure transfer cylinder 15, the edge area of ​​the paper sheet is compressed again. Since this compression is achieved under the joint action of mechanical and pressure forces, a stable curling structure will gradually be formed, and the curling operation steps are completed.
