The volute 32 is substantially fan-shaped and covers the upper half part of the turntable main body 30, an opening 321 is formed in the volute 32, and the position of the opening 321 corresponds to the station and corresponds to the arc-shaped stroke of the rotation of the first groove 31. The number of openings is set according to the needs of the station. And arranging a flanging assembly at the edge of the opening to process the workpiece to be processed in each station.

It should be noted that: the first flanging assembly is a roller assembly, a roller is arranged in the stroke of the workpiece to be machined, and when the facial tissue is rolled from one side of the roller to be attached to the roller, the corresponding flanging part can be folded and formed; the second flanging component is of an air cylinder shovel plate structure, a workpiece is not moved, and the air cylinder drives the shovel plate to shovel the flanging position of the surface paper so as to fold the surface paper into a shape. There are many forms of construction available in the applicant or patent of the prior application, all of which may be selected.

The volute is locked and matched or integrally formed by a sealing plate 322 and two fan-shaped baffles, wherein the sealing plate is positioned on the circumferential surface, and the fan-shaped baffles are positioned on the disk surface. When one of the first recesses is horizontal, one end of the sealing plate 322 is flush with the upper edge of the first recess, which together form the inlet station. When the pre-formed surface paper and the supplied materials of the inner box enter from the inlet station, the rotary disc rotates, and the rear outer surface 21 of the surface paper is limited by the port of the sealing plate 322 to be folded and attached to the inner box. The turntable continues to rotate to the next station, the second flanging assembly arranged at the opening edge of the station firstly carries out edge-shoveling forming on the rear side ears 218 at the two ends of the rear outer surface 21 of the facial tissue, and continues to rotate, and the first flanging assembly arranged at the edge of the station carries out roll forming on the two side outer surfaces 22.

The rotary table forming mechanism has the advantages that the stroke among the stations is coherent and short, and the rotary table forming mechanism is suitable for coping with the production condition of doubling the productivity. The degree of integration on individual workstations may continue to increase. For example, in order to ensure the forming quality of the pasting, the volute is also provided with the extrusion assembly, and pressure maintaining is conveniently carried out on each forming surface in time in the forming process or after the forming of the paper box.

After the surface paper is glued, the surface paper needs to be pressed and foamed in time to ensure the gluing quality of the glue, and the standard of one-time gluing and one-time pressing is usually applied in the packaging industry, namely the surface paper is glued once and then pressed and foamed once to obtain reliable gluing quality.

On both sides of the second station, first squeezing assemblies 341 are provided, which can squeeze the two front side ears 138, the two rear side ears 218 and the two inner side faces 11 of the inner box in one piece before the two outer side faces 22 are folded and formed. The first groove at this station is then rotated further to fold the two side outer faces 22 over to form an outer layer covering the side inner faces.

After the side outer face 22 is folded and adhered, a second extrusion assembly 342 is arranged at the next station to maintain pressure and remove bubbles from the rear outer face 21. And the third extrusion assembly 343 maintains the pressure of the opposite outer face 22 and removes bubbles. The order of the two stations can also be reversed.
