ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mold washing device of a pulp product manufacturing apparatus, and more particularly, the present invention relates to a pulp product manufacturing apparatus which automatically washes a pulp collecting mold and prevents dispersed pulp material from remaining on a frame and in which guide columns are mounted between the frame and an upper fastening plate so as to serve as posts and to guide raising and lowering movement of upper squeezing means thereby to secure stability upon raising and lowering of the upper squeezing means.
2. Description of the Related Art
Conventionally, a pulp container is used for surrounding an outer contour of an electric home appliance or serves as a packaging receptacle for a precooked food. The pulp container provides advantages in that it can be quickly corroded upon being filled into land and can prevent a noxious component from being mixed with a food. Hereinafter, a construction of a conventional pulp product manufacturing apparatus will be described.
FIG. 10
is a schematic perspective view illustrating a conventional pulp product manufacturing apparatus. The apparatus includes a frame
100
. A forming tank
110
is mounted to a front portion of the frame
100
, and pulp material which is prepared by decomposing waste paper, is supplied into the forming tank
110
. A first lower mold LM
1
is actuated up and down through a first cylinder S
1
in the forming tank
110
and forces the pulp material to be sucked against a metal mesh M having a predetermined contour. A first upper mold HM
1
is actuated through a second cylinder S
2
. The first upper mold HM
1
heats and compresses the pulp material which is sucked against the first lower mold LM
1
, and then, sucks and moves the resultantly formed pulp material onto a second lower mold LM
2
. A movable member
120
is repeatedly moved above the forming tank
110
through a horizontal hydraulic cylinder S
5
, and second and third lower molds LM
2
and LM
3
are mounted to the movable member
120
. Second and third upper molds HM
2
and HM
3
are respectively actuated by third and fourth cylinders S
3
and S
4
. The second and third upper molds HM
2
and HM
3
repeatedly heat and compress the resultantly formed pulp material which is sequentially placed on the second and third lower molds LM
2
and LM
3
, and then, discharge a finally manufactured pulp product out of the apparatus.
Therefore, after the pulp material is sucked against the metal mesh M through raising and lowering movement of the first lower mold LM
1
, the resultantly formed pulp material is heated and compressed through raising and lowering movement of the first through third upper molds HM
1
, HM
2
and HM
3
and through forward and rearward movement of the second and third lower molds LM
2
and LM
3
, while being fed in a stepwise manner, thereby to finally manufacture the pulp product.
However, the conventional pulp product manufacturing apparatus constructed as mentioned above suffers from defects in that, since the apparatus serves as basic means for simply manufacturing the pulp product, a surface of the pulp product is roughed. Also, because a washing operation of the first lower mold is manually conducted, productivity is deteriorated. Further, due to the fact that unnecessary structures such as columns are mounted to the apparatus, a cost of the entire manufacturing apparatus is raised.
In other words, since the metal mesh of the first lower mold is manually washed, the pulp material is not completely removed from the metal mesh, and instead, remains on the metal mesh, whereby a defective proportion of end products is increased.
Moreover, while the manufacturing apparatus constructed as mentioned above can manufacture a packing case having a predetermined configuration, a food container or the like, it cannot manufacture a thick pulp plate.
Further, while guide shafts which are raised and lowered through an upper fastening plate, are disposed on a single upper plate which constitutes the upper molds, to guide raising and lowering movement of the upper molds, since the guide shafts are raised and lowered along with the upper molds, the manufacturing apparatus weighs too much, whereby a great deal of power is consumed by the cylinders. Furthermore, because the guide shafts extend only through the upper fastening plate, the upper molds are seriously fluctuated while being raised and lowered, whereby a defective proportion of end products can be further increased.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a pulp product manufacturing apparatus which automatically washes a pulp collecting mold and prevents dispersed pulp material from remaining on a frame and in which guide columns are mounted between the frame and an upper fastening plate in such a way as to serve as posts and guide raising and lowering movement of upper squeezing means, whereby quality of pulp products and productivity of the manufacturing apparatus are improved, an expense required for disposing separate columns can be saved, and it is possible to secure stability upon raising and lowering of the upper squeezing means.
Another object of the present invention is to provide a pulp product manufacturing apparatus in which a raising and lowering part constituting pulp collecting means is arranged outside a pulp fluid bath, whereby a volume of the pulp fluid bath is minimized, it is possible to prevent the raising and lowering part from being corroded due to pulp fluid or the pulp fluid from being solidified on the raising and lowering part, and a repairing operation for the raising and lowering part can be implemented in an easy manner.
Another object of the present invention is to provide a pulp product manufacturing apparatus in which a forward and rearward moving part constituting lower squeezing means is disposed below a movable member, whereby it is possible to prevent foreign substances such as pulp material from flowing into a cylinder constituting the forward and rearward moving part.
Another object of the present invention is to provide a pulp product manufacturing apparatus in which an angle of each of a plurality of nozzles mounted to a lower surface of a washing body can be adjusted depending upon a configuration of a collecting mold part, whereby a removing effect for the pulp material remaining on a metal mesh of the collecting mold part can be elevated.
Another object of the present invention is to provide a pulp product manufacturing apparatus which can manufacture a thick pulp plate having a proper thickness.
Still another object of the present invention is to provide a pulp product manufacturing apparatus in which hot wires are arranged in a horizontal direction in a hot plate constituting a heating part of the upper squeezing means, whereby a hot wire changing operation can be implemented without disassembling the raising and lowering part from the apparatus, and thereby, it is possible to quickly repair the hot wires as occasion arises.
Yet still another object of the present invention is to provide a pulp product manufacturing apparatus in which only upper molds constituting the upper squeezing means are heated, whereby heat loss is minimized and a preheating time is shortened when arranging the manufacturing apparatus for a manufacturing procedure.
In order to achieve the above object, according to one aspect of the present invention, there is provided a pulp product manufacturing apparatus comprising: a body having a frame and an upper fastening plate, the frame having a pulp fluid bath in which pulp collecting means including a collecting mold part capable of squeezing pulp and discharging water and a raising and lowering part is disposed, the upper fastening plate being disposed at a predetermined separation from an upper end of the frame; first through third upper squeezing means respectively having u
