Description

Pulp mold system

The present invention relates to a pulp mold system, and more particularly, in a pulp mold system for producing pulp molds such as buffer packaging materials and food containers using pulp including waste paper, by improving the molding process of the pulp mold and forming time The present invention relates to an improvement of the pulp molder system for shortening and thus improving productivity.

In general, the pulp mold is applied to a buffer packaging material and various containers for protecting various items by using waste paper or pulp, and is an environmentally-friendly product that replaces styrene poly (EPS) manufactured through existing synthetic resins.

The pulp mold as described above has no advantage of generating environmental pollutants during disposal or incineration due to its material made of pulp, and has the advantage of being recycled upon recovery. In addition, the manufactured products are excellent in breathability and shock absorption compared to the existing styropol, and can be expressed in various shapes and colors, the use range is gradually expanded.

Looking briefly at the manufacturing process of such a pulp mold,

'Pulping process' to decompose waste paper or pulp → 'Raw material storage' to store decomposed raw material → 'Concentration control process' to control pulp concentration of stored raw material → 'Paper forming' to perform initial molding of product through molding mold '→' Forming process' to mold paper-formed product into accurate shape → Multiple 'drying process' (1st, 2nd ,,,) to dry molded product → Pulp mold through' finish 'process Is prepared.

In order to manufacture such a pulp mold, preparation processes such as pulping, raw material storage and concentration control processes,

There are largely divided into molding processes such as papermaking, molding, and drying. Among them, a molding process requires a pulp mold system configured through a combination of various mechanical devices.

The pulp mold system for producing the pulp mold has been devised and applied as a variety of configurations and techniques, and the present applicant also allows the production of more efficient pulp mold through Utility Model Registration No. 165587 (pulp mold system).

Looking through the embodiment as shown in Figure 1 of the pulp mold system of various configurations as described above,

A lower molding mold 11 installed in the pulp solution tank 10 containing the pulp solution and the pulp solution tank 10, in which a pulp mold having a predetermined shape is formed;

It is installed to be elevated above the lower molding mold 11, has a shape to be fitted to the lower molding mold 11, to adsorb / separate the pulp mold 100 formed on the lower molding mold (11). An upper forming mold 13 having an air intake / exhaust hole (not shown) in which air is sucked / exhausted and a heater 12 for heating the pulp mold 100 adsorbed so that

At least one of the lower molding mold 11 and the upper molding mold 13, and having a shape to be fitted to the upper molding mold 13 and having a heater 14 for heating the pulp mold 100. One or more lower drying molds 15, and

It is installed on the upper part of the lower drying mold 15 to be elevated, the air intake / exhaust air is sucked / exhausted so as to adsorb / separate the pulp mold 100 and has a shape to fit to the lower drying mold 15 At least one upper drying mold 17 having a heater 16 for heating a hole (not shown) and the adsorbed pulp mold 100.

The pulp mold system 1 configured in this way,

First, the pulp solution is filled in the pulp solution tank 10 to adjust the water level so that the lower molding mold 11 is immersed in the pulp solution. Then, the pulp solution filled with the lower molding mold 11 is sucked into a predetermined surface on the mold surface. Papermaking is carried out so that the pulp is adsorbed by the thickness.

With the papermaking, the pulp solution of the pulp solution tank 10 is discharged, and the lower molding mold 11 is exposed out of the water, and the upper molding mold 13 located above is lifted by an elevating device 18 such as a cylinder. The pulp mold 100 adsorbed to the lower molding mold 11 is lowered to be fixed by adsorption.

The upper molding mold 13 adsorbing the pulp mold 100 as described above is restored through the elevating device 18, and then the lower part in which the heater 14 is embedded for complete molding and drying of the pulp mold 100. The drying mold 15 is moved between the upper and lower molding molds 13 and 11 so as to be positioned directly below the upper molding mold 13.

When the lower drying mold 11 is moved, the upper molding mold 13 is lowered again, and the pulp mold 100 adsorbed to the lower drying mold 15 is placed in the lower drying mold 15 and pressurized to a predetermined pressure to form a paper-molded pulp mold 100. Allow primary drying with complete shaping of

As described above, the upper molding mold 13 and the first lower drying mold 15, which have been subjected to the primary drying for a predetermined time, are restored, and the pulp mold 100 is placed in the first lower drying mold 15 at this time. .

As such, the pulp mold system 1 in which the upper molding mold 13 and the first lower drying mold 15 are restored to maintain an initial state performs papermaking molding through the upper and lower molding molds 13 and 11 described above. At this time, the first upper drying mold 17 is simultaneously lowered, and the pulp mold 100 is dried on the first upper drying mold 17 together with the drying of the pulp mold 100 placed in the first lower drying mold 15. In order to be moved to, the above-mentioned papermaking pulp mold 100 is made to work.

As described above, the pulp mold system 1 adsorbing the pulp mold 100 to the upper molding mold 13 moves the first lower drying mold 15 to operate the pulp mold 100 by operating the upper molding mold 13. ) To be formed and dried, and at the same time, the pulp mold 100 adsorbed by lowering and adsorbing the first upper drying mold 17 is pressed and dried on the second dry lower mold 15 '.

The lowered upper molding mold 13, the upper drying mold 17 and the lower drying mold 15 is restored, wherein each pulp mold 100 is the first lower drying mold 15 and the second lower drying mold It is kept at 15 '.

In the above state, the upper and lower molding molds 13 and 11 perform papermaking, and together with the first and second upper drying molds 17 and 17 ', the first and second lower mold molds 15 are simultaneously lowered. , 15 ') the pulp mold 100 is dried under pressure, and after the pressure drying, the pulp mold 100 is adsorbed to the first and second upper drying molds 17 and 17', thereby forming the upper forming mold. (13) and the pulp mold 100 adsorbed to the second upper dry mold 17 'when the first and second upper dry molds 17 and 17' are lowered to finish.

As described above, the pulp mold 100 is formed through the molding process through the upper and lower molding molds 13 and 11 and the drying process using the first and second phase and lower drying molds 17, 17 ', 15 and 15'. It is formed, and thus molding and drying is made through the same upper and lower molds (13, 11), to prevent the deformation caused by excessive shrinkage during drying to improve the quality.

The pulp mold system 1 as described above takes about 30 seconds to manufacture, and this manufacturing time is required for transfer from the upper and lower molding molds 13 and 11 to the paper making and the first lower drying mold 15. It's time to become.

Thus, in order to shorten the manufacturing time, the time required for papermaking should be reduced, but the time required for papermaking through the upper and lower molding molds (17, 15) is limited, and further time savings were impossible.

In this way, productivity cannot be improved due to the limited manufacturing time in the upper and lower molding molds 15 and 17. As a result, only the additional equipment of the pulp mold system acts as a solution for the productivity improvement, resulting in economical cost. It caused problems such as production cost increase due to cost burden.

Therefore, the present invention was devised to solve the above problems, and the lower molding mold was excluded during papermaking, and improved to a direct molding structure through the upper molding mold to shorten the overall pulp mold manufacturing time, and furthermore, the upper molding mold and the like. By forming a plurality of drying molds corresponding thereto, the purpose of the present invention is to improve the productivity of the pulp mold and thereby reduce the production cost.
