Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a paper feeding device for the cake bottom paper. Background Art

[0002] A cake bottom is a base for supporting the cake body, and its common shape is square (rectangular). The structure of the cake bottom includes a bottom paper, a foam board and a surface paper. The size of the foam board is slightly smaller than that of the bottom paper. The foam board is located above the bottom paper. The surface paper completely wraps the foam board and is fixedly attached to the edge of the bottom paper, so that the shape of the cake bottom is in a "basin" shape. In order to wrap the foam board, the surface paper structure is composed of a square cardboard and four flipping pieces. The four flipping pieces are connected to the four side edges of the square cardboard. By folding the flipping pieces, the originally flat surface paper can be turned into an uncovered box structure. The cavity formed by this box is used to accommodate the foam board.

[0003] During the production process of the cake bottom, the surface paper as a raw material is in a stacked state and needs to be supplied to the production line one by one. In order to reduce labor costs, it is necessary to develop an automatic paper feeding machine suitable for the surface paper. Summary of the Invention

[0004] The utility model provides a paper feeding device for the cake bottom; it solves the problem of automatically feeding the surface paper in the prior art that needs to be solved.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: A paper feeding device for the cake bottom, characterized in that it includes: a frame, on which there is a horizontal supporting plate and guiding baffles arranged on both sides of the supporting plate, and the supporting plate and the two guiding baffles define a horizontally distributed paper chute;

[0006] A vertical reciprocating mechanism is arranged on the frame, and its output end is provided with a lifting table. An upward suction cup assembly is arranged on the lifting table, and a slot for the suction cup assembly to pass through up and down is arranged on the supporting plate;

[0007] A horizontal reciprocating mechanism, the reciprocating movement axis of which is parallel to the paper chute, the horizontal reciprocating mechanism is fixed on the frame, and its output end is provided with a push block, and the push block can push the paper in the paper chute away;

[0008] A paper stacking module is fixed above the supporting plate and the suction cup assembly, and includes a bottom plate and a plurality of limiting rods vertically arranged on the upper side of the bottom plate. A paper stacking cavity is defined inside the plurality of limiting rods. A paper taking opening smaller than the paper is arranged on the bottom plate, and the suction cup assembly is located within the projection range of the paper taking opening.

[0009] The suction cup assembly of the utility model requires an external negative pressure air pump and a corresponding air circuit control valve, but this is a basic capability possessed by those skilled in the art and will not be elaborated here. The cardboard stacking module of the utility model is used to store stacked surface paper, and the size of the paper taking port is slightly smaller than the unfolded size of the surface paper, so that the stacked surface paper can be stably stacked on the upper side of the bottom plate; in the initial state, the vertical reciprocating mechanism controls the lifting platform to be in a low position, at which time the highest point of the suction cup assembly is not higher than the upper surface of the support plate, and the horizontal reciprocating mechanism adjusts the position of the push block to avoid the projection range of the cardboard stacking module, and then the vertical reciprocating mechanism controls the lifting platform to rise until the suction cup assembly abuts against the bottom layer of surface paper in the cardboard stacking module. At this time, the suction cup assembly is in a negative pressure state, the surface paper will be sucked by the suction cup assembly, and then the vertical reciprocating mechanism controls the lifting platform to descend, the surface paper will be pulled downward, and the edge of the surface paper will undergo adaptive bending deformation after contacting the paper pickup port until it is completely pulled out, and finally the surface paper will be supported by the support plate, the suction cup assembly returns to normal pressure and separates from the surface paper, and then the horizontal reciprocating mechanism drives the push block to move, and the push block can push the surface paper on the support plate along the paper jam chute. The area after the surface paper is pushed out is the subsequent production station, and this completes one surface paper loading.

[0010] Furthermore, at least two step blocks are provided at the bottom of the bottom plate and at the edge of the paper taking port, and the step blocks are evenly distributed on the edge of the paper taking port. An inclined step surface is provided on the step block, and the upper end of the step surface is connected to the edge of the paper taking port, and the lower end is inclined toward the center of the paper taking port, and a number of continuous steps are formed on the step surface. Because in actual use, due to the good mutual adhesion of the stacked surface papers, when the bottom surface papers are quickly torn apart, due to the large negative pressure generated between the surface papers, there is a certain probability that multiple sheets of surface papers will be removed in one action. For this reason, the utility model is equipped with step blocks. During the descent of the surface paper, its edge will continuously engage, deform, and fall off with the step surface of the step blocks. In this process, the surface paper that is brought out will eventually be stuck by the step blocks, so it can be ensured that only one sheet of surface paper will be output each time the feeding action is performed, and the stuck surface paper will be removed by the subsequent feeding action.

[0011] Furthermore, the side wall of the paper outlet is tilted inward from top to bottom. This design can guide the edge of the surface paper to deform. At the same time, transferring the step surface of the step block to the side wall of the paper outlet also falls within the scope of protection of the utility model.

[0012] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The cardboard stacking module is used to store stacked surface paper, and the vertical reciprocating mechanism controls the lifting platform to rise until the suction cup assembly abuts against the bottom layer of surface paper in the cardboard stacking module. At this time, the suction cup assembly is in a negative pressure state, and then the vertical reciprocating mechanism controls the lifting platform to descend, and the surface paper will descend synchronously, and finally the surface paper will be supported by the support plate, and the suction cup assembly returns to normal pressure and separates from the surface paper, and then the horizontal reciprocating mechanism drives the push block to move, and the push block can push the surface paper on the support plate along the cardboard slide groove. The area after the surface paper is pushed out is the subsequent production station, so that the utility model can automatically and continuously load; 2. The utility model is equipped with a step block. During the descent of the surface paper, its edge will continuously engage, deform, and fall off with the step surface of the step block. In this process, the surface paper that is brought out will eventually be stuck by the step block, so it can be guaranteed that only one sheet of surface paper will be output each time the loading action is performed.

[0022] The cardboard stacking module 400 is fixed above the supporting plate and the suction cup assembly, and includes a base plate 410 and six limit rods 420 vertically arranged on the upper side of the base plate. The interior of the six limit rods defines a paper stacking cavity 430. The base plate is provided with a paper taking-out port 440 whose size is smaller than that of the cardboard, and the suction cup assembly is located within the projection range of the paper taking-out port.

[0023] The suction cup assembly in this embodiment requires an external negative pressure air pump and a corresponding air circuit control valve, but this is a basic capability possessed by those skilled in the art and will not be elaborated here. The cardboard stacking module of this embodiment is used to store stacked sheet paper, and the size of the paper taking port is slightly smaller than the unfolded size of the sheet paper, so that the stacked sheet paper can be stably stacked on the upper side of the bottom plate; in the initial state, the vertical reciprocating mechanism controls the lifting platform to be in a low position, at which time the highest point of the suction cup assembly is not higher than the upper surface of the supporting plate, and the horizontal reciprocating mechanism adjusts the position of the push block to avoid the projection range of the cardboard stacking module, and then the vertical reciprocating mechanism controls the lifting platform to rise until the suction cup assembly abuts against the bottom layer of sheet paper in the cardboard stacking module, at which time the suction cup assembly is in a negative pressure state, and the sheet paper will be sucked by the suction cup assembly, and then the vertical reciprocating mechanism controls the lifting platform to descend, and the sheet paper will be pulled downward, and the edge of the sheet paper will be adaptively bent and deformed after contacting the paper taking port until it is completely pulled out, and finally the sheet paper will be supported by the supporting plate, and the suction cup assembly returns to normal pressure and separates from the sheet paper, and then the horizontal reciprocating mechanism drives the push block to move, and the push block can push the sheet paper on the supporting plate along the cardboard chute, and the area after the sheet paper is pushed out is the subsequent production station, so that one sheet paper loading is completed.

The upper end of the step surface is connected to the edge of the paper taking port, and the lower end is inclined toward the center of the paper taking port. Several continuous steps are formed on the step surface. Because in actual use, due to the good mutual adhesion of the stacked surface papers, when the bottom surface papers are quickly torn apart, due to the large negative pressure generated between the surface papers, there is a certain probability that multiple sheets of surface papers will be removed in one action. For this reason, step blocks are added to this embodiment. During the descent of the surface paper, its edge will continuously engage, deform, and fall off with the step surface of the step blocks.
