Embodiment 1

[0031] In an exemplary embodiment of the present invention, as Figure 1-Figure 3 As shown, a cardboard stamping and forming device is given.

[0032] like figure 1 The shown cardboard stamping and forming device is used for stamping and forming paper-based materials to obtain paper containers, especially for stamping and forming of cardboard 3, by deforming the cardboard 3 twice in opposite directions, the deformation ability of the entire area of ​​the cardboard 3 is exerted, and the The deformable amount of the cardboard 3 can reduce cracks, breakage and other problems during the forming process, and improve the forming depth of the paper container.

[0033] The cardboard stamping and forming device mainly includes a stamping element for providing stamping action and a pressing component 4 for providing pre-deformation. 3. Pre-deformation is generated, and the direction of the pre-deformation is opposite to the required stamping and forming direction, and then the pressin...

Embodiment 2

[0051] In another exemplary embodiment of the present invention, as Figure 1-Figure 3 As shown, a cardboard stamping forming method is given.

[0052] Cardboard stamping and forming methods, including:

[0053] Along the thickness direction of the cardboard 3, the multi-layer cardboards 3 are stacked in sequence, and the stacked cardboards 3 are deformed together;

[0054] Clamp the edge of the cardboard 3 and apply a pre-action force to the cardboard 3, so that the cardboard 3 has a pre-deformation in the opposite direction to the stamping deformation;

[0055] Keeping the pre-acting force, press the cardboard 3, and overcome the pre-acting force to produce the punching deformation of the cardboard 3.

[0056] In order to keep the paperboard 3 in a proper deformation state, one or more parameters of pressure, temperature and humidity acting on the paperboard 3 are controlled when the pre-force is applied.

[0057] In addition, it is also necessary to adjust the temperatur...

Abstract

The invention provides a paperboard stamping forming device and method, and relates to the technical field of paper material stamping forming equipment.The paperboard stamping forming device comprises a male die and a pressure applying assembly, and the pressure applying assembly acts on a paperboard through a fluid medium; before the male die conducts stamping forming on the paperboard, the pressing assembly enables the paperboard to be pre-deformed, and the pre-deformation direction is opposite to the stamping deformation direction. Aiming at the problem that the forming depth is difficult to meet the requirement due to the fact that an existing paper container formed by paperboards is limited by the deformation capacity of the paperboards, the forming depth of the paper container is improved by deforming the paperboards twice in opposite directions, exerting the deformation capacity of the whole area of the paperboards, improving the deformation amount of the paperboards, reducing the problems of cracks, damage and the like in the forming process and improving the forming depth of the paper container.

Description

technical field [0001] The invention relates to the technical field of paper material stamping and forming equipment, in particular to a cardboard stamping and forming device and method. Background technique [0002] Compared with traditional plastic containers, paper containers made of paper-based materials, such as paper cups, paper plates, and paper bowls, have the characteristics of low cost, high environmental friendliness, and good sustainability, especially in packaging that is widely used in containers. field. At present, most paper container manufacturing methods on the market use two-piece bonding or pulp molding, both of which are relatively mature. However, the two-piece bonding has the defect of a lot of waste, and liquid leakage is easy to occur in the bonding area. The production efficiency of pulp molding is low, and there are problems such as high energy consumption in the drying process. [0003] The production of seamless paper containers can be achieve...
