Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a three-dimensional bending process of pulp molding. The pulp molding obtains a box body with a draft angle, and there are planes around the box body. The angled products effectively solve the problem that the pulp molding integrated products with vertical angles cannot be obtained at present

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them; based on The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] A pulp molding three-dimensional bending process, such as figure 2 shown, including the following steps:

[0029] (1) A box body 4 with a draft angle of 3-5° is obtained by pulp molding, and there are planes around the box body, and there is no draft problem in pulp molded plane products;

[0030] (2) V grooves are opened along the sides 401 around the box body, and the planes around the box body are cut neatly to obtain the bent edge 4...

Abstract

The invention relates to the technical field of pulp molding, and discloses a pulp molding and three-dimensional bending method. A box body with a draft angle is obtained through pulp molding, the periphery of the box body is provided with a plane, a product with a vertical angle is obtained through bending, and the problem that a pulp molding integrally-formed product with the vertical angle cannot be obtained at present is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of pulp molding, in particular to a three-dimensional bending process of pulp molding. Background technique [0002] All-pulp molding products are produced by direct demoulding of all pulp, so it is an integrated product without refolding or jacking, etc. The materials used for all-pulp molding are bamboo pulp, wood pulp, sugarcane pulp, etc., which are completely degradable Pulp is an environmentally friendly material that reduces the pressure of environmental degradation. Such as Figure 4 As shown, the side wall of the forming mold of the all-pulp molded product cannot be a vertical side wall, and must have a draft angle of 3-5°. The intersection of the two sides can only be rounded, otherwise the formed product is difficult to demould smoothly The side walls of the resulting pulp molded product also had a slope of 3-5°. However, when the customer needs such as Figure 5 Existing techniques cannot obta...
