Problems solved by technology
[0005] The present invention can solve the problem that the existing equipment cannot adjust the two sides of the pulp molded lining at the same time when the pulp molded lining is hot-pressed and shaped, and the phenomenon that the angles of the two sides of the pulp molded lining are inconsistent after adjustment is easy to occur, thereby It reduces the success rate and shaping effect of pulp molded lining. At the same time, it is impossible to heat press and shape pulp molded linings of different sizes, thereby reducing the applicability of the equipment. Moreover, it is impossible to heat the pulp before hot pressing The molded lining is rolled and flattened, and it is easy to have problems such as surface unevenness after hot pressing and shaping

Embodiment Construction
[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0033] Such as Figure 1 to Figure 6 As shown, in order to achieve the above object, the present invention adopts the following technical scheme, a method for manufacturing a pulp molded inner packaging material, which uses a pulp molded inner lining packaging material manufacturing equipment, the pulp molded inner lining packaging material The production equipment includes a bottom plate 1, a receiving device 2, an adjusting device 3 and a molding device 4. The specific method for making the pulp molded lining packaging material by using the above pulp molded lining packaging material production equipment is as follows:
[0034] S1. Equipment inspection: Before the equipment is used, the equipment is routinely inspected manually;
[0035] S2. Mold...

The invention relates to a manufacturing method of a paper pulp molding lining packaging material, which comprises a bottom plate, bearing devices, adjusting devices and profiling devices, the bearingdevices are evenly installed at the upper end of the bottom plate, the adjusting devices are arranged on the outer sides of the bearing devices in a bilateral symmetry mode, the adjusting devices areconnected with the bottom plate in a sliding fit mode, and the profiling devices are arranged above the bearing devices. According to the invention, the problems that the existing equipment carries out hot-pressing shaping on the molded pulp lining; the two sides of the molded pulp lining cannot be adjusted at the same time; after adjustment, the phenomenon of inconsistent angles on two sides ofthe molded pulp lining is easy to occur; according to the shaping device for the molded pulp lining, the shaping success rate and the shaping effect of the molded pulp lining are reduced, and meanwhile, molded pulp linings of different sizes cannot be subjected to hot-pressing shaping, so that the applicability of equipment is reduced, the molded pulp lining cannot be subjected to roll flatteningtreatment before hot-pressing shaping, and the phenomenon that the surface is uneven easily occurs after hot-pressing shaping is solved.
Description
technical field [0001] The invention relates to the technical field of manufacturing molded packaging materials, in particular to a method for manufacturing pulp molded inner lining packaging materials. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, and molds a certain shape of paper products on a molding machine with a special mold. It has four advantages: the raw material is waste paper, including cardboard, waste paper Box paper, waste white edge paper, etc., have a wide range of sources; the production process is completed by pulping, adsorption molding, drying and shaping, etc., which is harmless to the environment and can be recycled and reused. The volume is smaller than that of foamed plastics and can be overlapped. Convenience; pulp molding, in addition to lunch boxes, tableware, more industrial cushioning packaging, the development is very rapid. [0003] At present, the existing equip...
