Embodiment 1

[0040] A kind of pulp molding product of this embodiment solves the equipment for hanging pulp on the back, and according to the sequence of preparation of pulp molding products, it includes: a pulp suction mold 2 forms a wet embryo after sucking pulp from the pulp tank 1; an extrusion mold 3 is arranged on Slurry suction mold 2 corresponds to the upper side. After the slurry suction mold takes the wet embryo upwards and reverses it, it will squeeze the wet embryo with the extrusion mold 3 for the first time; the hot pressing upper mold 4 can move up and down in the vertical direction; the hot pressing lower mold 5 can Move left and right along the horizontal direction, and when moving to correspond up and down with the hot pressing lower die 5, carry out hot pressing treatment to the wet embryo.

[0041] Wherein, suction mold 2, refer to Figure 4As shown, it includes a suction cavity, which is connected with a vacuum pump through a solenoid valve. It is in a vacuum state whe...

Embodiment 2

[0046] A kind of pulp forming product of this embodiment solves the equipment for hanging pulp on the back, see Image 6 As shown, it includes slurry suction, extrusion, hot pressing, transfer, after the slurry suction mold sucks slurry from the pulp tank 1, it turns over, squeezes with the extrusion mold 3 arranged on it, and turns over again after extrusion, at this time , the hot-pressing lower die 5 moves to the left below the slurry-suction die 2, and the slurry-absorbing die 2 places the wet embryo in the hot-pressing lower die 5. At this time, station 1 is formed, and the hot-pressing lower die 5 moves to the right The position corresponding to the hot-pressing upper die 4 forms a station 2. At this time, the hot-pressing upper die 4 moves vertically downwards, and the hot-pressing lower die 5 squeezes the wet embryo and heats it for shaping. Because the hot-pressing upper die 4 There is an air suction structure inside, and an air blowing structure is provided inside th...

Abstract

The invention discloses a method for solving back pulp hanging of a paper pulp molding product. The system sequentially comprises a pulp suction mold, an extrusion mold, an upper hot pressing mold, alower hot pressing mold and a transfer mold according to the preparation sequence of the paper pulp molding product, wherein an air blowing and sucking structure is arranged in the pulp suction mold;an air suction structure is arranged in the extrusion mold; and the slotted hole of the air blowing and sucking structure in the pulp suction mold is opposite to the slotted hole of the air sucction structure in the extrusion mold. The optimized pulp molding forming system provided by the invention has the following advantages: through improvement of partial link structures, the problem of orangepeel on the surface of a product is solved; and the finishing time of the product is saved.

Description

technical field [0001] The invention relates to the technical field of molding preparation, in particular to a system for solving the problem of back pulping of pulp molding products. Background technique [0002] In recent years, with the increasing demand for manufacturing products, especially outer packaging manufacturing products, the appearance and quality of molded products have been greatly improved from the surface, but behind it is high cost and high pollute. In order to improve the yield rate of finished products, enterprises have invested a lot in the improvement and processing of molds. In order to obtain molded products with smooth surfaces, they have added unenvironmentally friendly substances to raw materials or laminated films on the surface of finished products. [0003] In the pulp molding production process with plant fiber as the main raw material, the pulp suction mold is lowered below the pulp level of the pulp storage tank, and the vacuum negative pre...
