Description

Technical Field

[0001] The present application relates to the technical field of paper cup cover assembly, in particular to a paper cup cover die-cutting and laminating device. Background Art

[0002] The production of existing paper cup lids with filters requires a strong bond between the filter structure and the lid, which are made of different materials. Adhesive bonding places high demands on the glue used, requiring food-grade glue. The glue must not delaminate or crack under the action of steam (100°C), and must not produce any toxic or harmful substances under the action of steam. High-pressure stamping, however, can cause the filter and lid to deform under the action of steam, resulting in separation.

[0003] Therefore, it is difficult for ordinary paper cup cover production equipment to produce qualified paper cup covers with filters. Utility Model Content

[0004] In this embodiment, a paper cup cover die-cutting and laminating device is provided to solve the problem that conventional paper cup cover production equipment in the prior art is difficult to produce paper cup covers with filters.

[0005] According to one aspect of the present application, a paper cup lid die-cutting and laminating device is provided, comprising: a fixed bracket, an electric push rod, a heating mechanism, a support base and a die-cutting tool, wherein the support base is fixedly arranged on the upper surface of a paper cup lid processing platform, the fixed bracket is fixedly arranged on the upper surface of the processing platform, the top end of the fixed bracket is fixedly connected to the electric push rod, the bottom end of the electric push rod is fixedly connected to the heating mechanism, the upper surface of the support base is fixedly arranged with a die-cutting tool, the heating mechanism is used to bond and fix the paper belt and the filter belt, and the die-cutting tool die-cuts the bonded and fixed paper belt and the filter belt to form the outline of the filter window.

[0006] Preferably, the heating mechanism is an ultrasonic generator or a heating plate.

[0007] Preferably, a groove is provided at a preset position on the side of the die-cutting tool. When the ultrasonic generating mechanism is pressed down by the electric push rod, the paper belt and the filter belt are die-cut. Through the groove on the side of the die-cutting tool, the contours on the paper belt and the filter belt are connected through the connection point, so that the paper belt and the filter belt never separate when cutting the filter window.

[0008] Preferably, the outline shape of the die-cutting tool is circular, elliptical, fan-shaped, square, rectangular, regular hexagonal, petal-shaped or cross-shaped.

[0009] Preferably, the number of the grooves is two or more.

[0010] Preferably, the plurality of grooves are evenly distributed on the side of the die-cutting tool.

[0011] Preferably, the width of the groove is less than or equal to a first preset threshold, and the width between every two grooves is greater than a second preset threshold.

[0012] The above-mentioned technical solution of the present application solves the problem in the prior art that conventional paper cup lid assembly equipment cannot quickly and effectively install the filter screen of the paper cup lid when assembling the paper cup lid with a filter screen. The present application uses the extension of the electric push rod to drive the heating mechanism to move, thereby heating the paper belt through the heating mechanism, so that the hot melt adhesive coating on the surface of the paper belt is melted and adhered to the filter screen belt. The filter screen of the paper cup lid can be automatically assembled with high efficiency and fast assembly, and the paper cup lid can be assembled efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Through the above technical solution, the filter screen can be automatically assembled on the paper cup cover, which is highly efficient and quick to assemble, and the paper cup cover can be assembled efficiently.

[0028] See Figure 2 The paper cup lid die-cutting and laminating device 7 of the present invention includes a fixed bracket 701, an electric push rod 702, a heating mechanism 703, a support base 704 and a die-cutting tool 705. The support base 704 is fixedly arranged on the upper surface of the processing platform 1, and the fixed bracket 701 is fixedly arranged on the upper surface of the processing platform 1. The top end of the fixed bracket 701 is fixedly connected to the electric push rod 702, and the bottom end of the electric push rod 702 is fixedly connected to the heating mechanism 703.

[0029] Through this technical solution, the extension of the electric push rod A702 can drive the heating mechanism 703 to move, thereby heating the paper belt 4 through the heating mechanism 703, so that the hot melt adhesive coating coated on the surface of the paper belt 4 melts and is bonded and fixed to the filter belt 5.

[0030] like Figure 1 and Figure 2As shown, the paper belt 4 in the present application utilizes the winding roller B3 to reel in the paper material of the filter screen, so as to facilitate traction, movement and guidance. Similarly, the filter screen belt 5 utilizes the winding roller B3 to reel in the filter screen material of the filter screen, so as to facilitate traction, movement and guidance.

[0031] The heating mechanism 703 may be an ultrasonic generator or a heating plate.

[0032] A die-cutting tool 705 is fixedly provided on the upper surface of the support base 704. Figure 3 The die-cutting tool 705 is provided with a groove on the side. Through the technical solution, through the setting of the die-cutting tool 705, when the heating mechanism 703 is pressed down, the paper belt 4 and the filter belt 5 can be die-cut, thereby cutting out the contour corresponding to the filter window. At the same time, through the groove on the side of the die-cutting tool B705, the contour on the filter belt 5 is connected through the connection point, achieving the effect of only cutting but not separating.

[0033] like Figure 3 As shown, the outline shape of the die-cutting tool 705 is circular. In the embodiment of the present invention, the outline shape of the die-cutting tool 705 is not limited and can be Figure 3 The circle in the figure can also be an ellipse, a fan, a square, a rectangle, a regular hexagon, a petal shape or a cross.

[0037] Preferably, the first preset threshold is smaller than the second preset threshold.

[0038] In the present application, the contours on the filter belt 5 are connected through the connection points through the grooves on the side of the die-cutting tool B705, so as to achieve the effect of only cutting but not separating. In the subsequent process, the filter window needs to be separated from the paper belt 4 and the filter belt 5. Therefore, the connection point should not be too large, and the separated part formed after die-cutting should not be too small. Therefore, the width of the groove needs to be less than or equal to the preset threshold, and the width between each two grooves needs to be greater than the preset threshold. In the present application, the width of the groove can be the straight-line length of the two end points of the groove, or it can be the arc length corresponding to the groove. The width between each two grooves can be the straight-line length of the two adjacent end points of the two grooves, or it can be the arc length corresponding to the two adjacent end points of the two grooves.

[0039] In the embodiment of the present invention, a heating mechanism 703, in particular an ultrasonic generator, is used to heat the paper belt 4 and the filter screen belt 5, so that the hot melt adhesive coating coated on the surface of the paper belt 4 melts and penetrates the pores of the filter screen, thereby enabling the paper cup cover and the filter window to be bonded together in a subsequent process, so that the paper cup cover and the paper belt penetrate the pores of the filter screen and are bonded together, thereby forming a finished paper cup cover with a filter screen.
