Description

Pulp moulding equipment with turner for transferring wet blank

Technical Field

The utility model relates to a device for manufacturing plant fiber (paper pulp for short) products including paper pulp by adopting a molding forming mode; is suitable for manufacturing disposable plant fiber molding products, in particular disposable non-planar paper products; such as paper pulp molding delicate packaging products, plant fiber (paper pulp) molding tableware, plant fiber (paper pulp) molding trays, plant fiber (paper pulp) molding industrial product shock pads, packaging boxes and packaging trays, disposable non-planar plant fiber (paper pulp) molding decorative three-dimensional wallboards (or called plant fiber three-dimensional wallpaper or paper pulp molding three-dimensional wallpaper) and all disposable plant fiber (paper pulp) molding products, and the fully-automatic plant fiber molding machine (equipment) comprises a fully-automatic paper pulp molding machine (equipment).

Background

The manufacturing process of the plant fiber molding product comprises the following steps: the plant fiber is first suction filtered and formed in a suction filter forming device to produce wet blank of the product, the wet blank is fed into a hot pressing mold of a hot pressing and forming device, the hot pressing mold is closed and the wet blank is hot pressed, dried and formed to produce plant fiber molded products in various shapes. And (3) conveying the wet blank from the suction filter forming die to a hot pressing die, sucking the wet blank from the suction filter forming die by using a wet blank transfer die in a wet blank transfer device, and directly conveying the wet blank into the hot pressing die of a hot pressing and shaping device.

Because the thickness of the wet blank is thicker than that of the product after hot-press shaping, the wet blank is easy to crack or wrinkle when entering a hot-press shaping die, and the quality and the qualification rate of the product are influenced.

The hot-pressing die comprises a hot-pressing upper die and a hot-pressing lower die. In order to exhaust the air, the surface of the hot-pressing upper die or the hot-pressing lower die is covered with a metal wire mesh (generally a stainless steel wire mesh). Therefore, when the hot press mold is closed up and down, one surface of the hot press upper mold or one surface of the hot press lower mold is always covered with the wire mesh, which is called as a "mesh surface of the hot press mold", and the other surface is not covered with the wire mesh, which is called as a "smooth surface of the hot press mold". Because the installation of the wire mesh of the lower hot-pressing die is convenient and the vacuum pumping of steam of the lower hot-pressing die is convenient, the wire mesh of the hot-pressing die is also generally placed on the lower hot-pressing die. The 'net surface of the hot-pressing die' is suitable for being arranged on a lower die of the hot-pressing die.

The surface of the plant fiber molding product is formed by pressing the mesh surface of the hot-pressing die and the smooth surface of the hot-pressing die. Therefore, the surface of the produced plant fiber molding product, which is contacted with the net surface of the hot pressing mold, is provided with the reticulate pattern, and the other surface is not provided with the reticulate pattern. Respectively referred to as the "web side of the article" and the "smooth side of the article". If the net surface of the hot-pressing die is arranged on the lower die of the hot-pressing die, the produced product also has the structure that the net surface of the product faces downwards and the smooth surface of the product faces upwards.

The wet blank is formed by vacuum suction on a suction filter forming mould with one or more layers of wire mesh (generally stainless steel wire mesh) covered on the surface. The side contacting the suction screen during suction filtration molding is called the "wet-blank screen side". In the process of suction filtration forming, as the thickness of the wet blank increases, the suction force to the slurry is gradually reduced, the material of the wet blank is looser and irregular high-low peak valley surfaces are also formed, so that the surface far away from the suction filter screen (the back surface of the net surface of the wet blank) is called as the rough surface of the wet blank.

Generally, the working surface of the suction filter forming die with a stainless steel wire net as a suction filter screen is upward in a pulp tank for sucking pulp. Therefore, the ' net surface of the wet blank ' is arranged below the wet blank (the net surface of the wet blank faces downwards), and the ' rough surface of the wet blank faces upwards; even if the mold is a turnover type suction filter forming mold, the mold surface faces downwards to suck slurry in the slurry tank, the mold surface is turned upwards after the slurry suction is finished, and then wet blank transfer is carried out. Therefore, the wet blank formed by the production is also downward with the net surface of the wet blank facing downwards and upward with the rough surface of the wet blank facing upwards.

The movement of the wet blank is translation, namely the wet blank is formed in the suction filter forming die and is sent into a hot pressing die of a hot pressing and shaping device, and the orientation of the wet blank cannot be changed. The wet blank is sucked from the suction filter forming die and transferred to a hot pressing die for hot pressing and forming, and the result is that the rough surface of the wet blank corresponds to the smooth surface of the product and the net surface of the wet blank corresponds to the net surface of the product.

So far, the "product smooth surface" of the plant fiber molding product is not smooth, and the "product smooth surface" becomes a worldwide problem in the production of the plant fiber molding product. The "shiny side of the product" is not "shiny" mainly because of the wrinkles and looseness of the "matt side of the wet blank". The smooth surface of the hot-pressing die is difficult to polish the rough surface of the wet blank.

The wall thickness of the wet blank is thicker than that of the product, and the wet blank is easy to crack and wrinkle when entering a hot-pressing shaping die, and no effective method exists at present;

regarding overcoming the problem of poor smoothness of products, the existing common solution is to increase the mold clamping force of a hot-pressing mold and adjust the gap of the mold in reverse according to the surface effect of the products, and the gap of the mold is adjusted to be small when the product is not pressed. As a result, even if the mold clamping force of the hot-pressing mold is increased to be large, some parts of the product are pressed to be black and some parts are not pressed to be smooth, and the surface quality of the product is not obviously changed; it is also more troublesome: (1) The clearance of the die is reversely adjusted according to the surface effect of the product, so that great blindness is achieved, and the purpose is often difficult to achieve if the clearance is lost; (2) The cost for adjusting the die clearance is very high, the die clearance is adjusted by shutting down the machine and detaching the die to process the die again, the temperature of the die at about 200 ℃ needs to be reduced to normal temperature, a long time is needed, the heat energy loss is large, the time is too long, and the efficiency is low.

Therefore, the utility model discloses a method solves when hot pressing drying design, and the hot pressing mould is easy to the difficult problem of product fracturing and difficult product surface press polish.

In addition, in the manufacturing process of the plant fiber molding product, if the female die is adopted for pulp suction, the thickness of the bottom wall of the formed wet blank is thicker than that of the upper part, the deeper the product is, the more uneven the thickness of the wall of the wet blank is, the wet blank is easy to be cracked, and finally the produced product has uneven wall thickness and is easy to form cracked waste products; if the male die is adopted for absorbing the slurry, the wall thickness of a wet blank of a deep product can be uniform, but when the wet blank moves into a hot-pressing shaping device, the hot-pressing lower die also needs to correspond to the male die, and when the deep product is produced, if the hot-pressing lower die is the male die, the product is not easy to demould.

In the industry, the uniform wall thickness of the product and easy demoulding are two difficult choices. Therefore, a method for solving the problem is also needed.
