Technical Field

[0001] The utility model relates to a paper folding device, in particular to a folding device for cake base paper. Background Art

[0002] The cake tray is a base used to support the cake itself. Its common shape is square (rectangular). The structure of the cake tray includes base paper, foam board and cover paper. The size of the foam board is slightly smaller than the base paper. The foam board is located on the upper side of the base paper. The cover paper completely wraps the foam board and fits and fixes it to the edge of the base paper, making the cake tray look like a "dish" shape.

[0003] There is a cake base paper (see attached Figure 1 ), it comprises a square main board 1, four sides of which are extended with bending boards 2, the bending boards can form a first bending piece 3 and a second bending piece 4 after being bent, wherein the first bending pieces on the two facing bending boards are further extended with folding ears 5 at both ends, and after the cover paper is folded, the folding ears are attached to the first bending pieces on the adjacent bending boards (see attached Figure 2 ). In order to improve production efficiency and reduce labor costs, it is necessary to develop an origami device that can fold the paper automatically. Summary of the invention

[0007] The origami module group is provided with four groups and is distributed around and below the origami lower mold, including a first telescopic driver fixed relative to the base and a bending plate driven by the telescopic driver, wherein the moving path of the bending plate is inclined, and the telescopic driver can drive the bending plate to abut against the second bending portion of the origami upper mold in a downwardly pressed state;

[0008] The ear folding module is provided with two groups and is mirror-distributed on both sides of the origami lower module. The ear folding module comprises two bending inserts and a second telescopic driver for driving the bending inserts to reciprocate horizontally.

[0009] The operation process of the utility model is as follows: the surface paper to be bent is placed flatly and accurately into the origami lower mold through the automated paper loading equipment, the positioning component plays the role of positioning the surface paper, wherein the ear folding pieces on the surface paper and the ear folding modules are distributed correspondingly; then the paper pressing module is actuated, and the downward pressure driver pushes the origami upper mold downward; then the two groups of paper pressing modules located on the same side as the ear folding modules start to act, and the corresponding two bending plates are pushed out to abut against the second bending portion, during this process, the corresponding two bending plates on the surface paper will be bent into the contour of the bottom of the origami upper mold, wherein the surface paper will be bent twice at the first bending portion and the second bending portion; then the two ear folding modules are actuated at the same time, and the four bending inserts are moved toward the ear folding pieces of the surface paper at the same time, until the ear folding pieces are bent to fit the side wall of the punch; then the remaining two paper pressing modules are actuated, at which time the surface paper is folded, and finally the two ear folding modules and the four origami modules are reset in succession, and the paper pressing module controls the origami upper mold to rise and reset.

[0010] Furthermore, the origami upper die is provided with a plurality of through holes penetrating the male die, and negative pressure suction cups are provided in the through holes.
