Description

Paper tableware formation mould

The utility model discloses the paper tableware formation mould series of disposable box, bowl, dish, it belongs to machinery manufacturing technology field, also belongs to the tableware for food and drink technical field.

Modern society, people's health, environmental protection consciousness are more and more stronger; Health, the convenience of diet are more paid attention in the quickening of work rhythm.Use for convenience, need not washing, the disposable plastic tableware that needn't have enough to meet the need arises at the historic moment, and a time disposable plastic tableware becomes indispensable consumer goods in people's life.Because plastics never rot, never decompose, make its burning again because of the toxic gas contaminated air is arranged, brought long-range suffering, cause the new pollution problem of " white pollution " property to the mankind, therefore, developed country makes laws one after another and forbids producing, uses the disposable plastic tableware in the world.Paper table ware and food bag are widely current abroad.Some cities of China and the Ministry of Railways also ban use of the disposable plastic tableware in succession, and regulation is used dispensable paper tableware.

In order to seek a kind of can the decomposition by natural environment, can produce, make things convenient for the raw material of the material of use again fast as disposable tableware, for example utilize the solubility modified starch to add cellulose compression moulding; Utilize the moulding of wood fragments High Temperature High Pressure to make various disposable tablewares.Yet the required investment of production equipment of these technologies is big, and product cost is more much higher than disposable foaming plastic tableware, is difficult for being adopted by market.With paper is raw material, and external paper tableware production must be used high-quality wood pulp paper, and equipment investment is big, and China's overwhelming majority paper are straw papers in addition, can't with the supporting use of overseas equipment.

The purpose of this utility model is: owing to the greatest drawback that with the native paper is raw material processing paper tableware is that the native paper fiber is short, fragility is big, easily break when shaping, be difficult to be processed into the paper tableware of different shape, for overcoming these deficiencies, propose a kind of formation mould of meter, to increase paper intensity, help moulding, make the paper of inextensibility can produce various tablewares by mould pressing technology as foamed plastic equally.

For realizing that the technical measures that the purpose of this utility model is taked are: paper tableware formation mould of the present utility model is made up of box body die, box body punch, punch upper padding plate, box body stripping attachment, first spring, top board, lid stripping attachment, second spring, lid punch, lid die, moulding guide post, material level plate, heating collar, the 3rd spring.

The body protruding, die of box body and/or lid is suitable, and the length of punch or diameter are than the little 2.0～3.0mm of die.The punch upper padding plate links to each other with the broadside face (being the lower surface on protruding top) of punch; The die device is in heating collar; The stripping attachment device of protruding, die is shaped as " T " font at the center of mould, and bar is with spring outward; The die case device is in the material level plate, and die top broadside becomes a plane with the material level plate.

The used main raw material of the utility model is the white board of all size: the two-sided white board of whole wood pulp; The two-sided white board of mixed pulp; Herb is starched two-sided white board; Herb slurry single face white board; Herb is starched two-sided composite sheet.Make general 320～400 gram/m of use of paper lunch box ²The paper of specification, making bowl, dish generally use 200～280 gram/M ²The paper of specification.It is main raw material that the inventor also succeeds in developing with the yellow plate paper, two-sidedly brightens processing, and its outward appearance and white board are similar.

The box body mould of box of the present utility model, bowl, dish mainly is made of the concave, convex mould respectively, and length and width or diameter can be made mould on demand, and the volume of box body is 450～600ml, and the volume of bowl is 200～500ml, and the plate diameter is 180～220mm.All leave and the rectangular broadside of wall in the upper end of box, bowl, dish, be provided with a stripping attachment that spring is housed in the center of the bottom surface of mould, when making the cardboard punch forming, stripping attachment is pressed down consistent with the die bottom surface.After moulding, lift punch, but stripping attachment under no upward pressure with box, bowl, dish jack-up and the material returned.For punch forming, should in advance cardboard be cut into certain size and dimension, and on the broadside of die upper end, be provided with 4～8 moulding guide posts that spring is housed symmetrically, spring is contained in the moulding guide post, it is a key technology, it can make the moulding that is superimposed regularly of the curved surface of box, bowl, dish when moulding.

Make the whole lid punch forming that is linked to be that cuts, need utilize protruding, the negative mold punch forming of lid, on the broadside curved surface of die upper end 4～8 moulding guide posts that have spring are housed symmetrically, this also is a key technology, and it can make the moulding that is superimposed regularly of tray cover curved surface.The moulding guide post stretches out die upper end broadside plane 8～20mm, and when punch and die matched moulds, can contract to die edge level in the guide post top.

Box, bowl, dish die case are packed in the heating collar, and the cardboard that is cut into is heated along the die inner rim, periphery position bending when being beneficial to punching press.

Compared with the prior art, the technique effect that the utility model has reached: adopt the utility model mould and cooperate technology, overcome the weakness that the paper inextensibility is not suitable for mold pressing, made the cardboard of inextensibility produce various tablewares by mould pressing technology as foamed plastic.And on the broadside of die upper end symmetrically arranged moulding guide post, can make the shaping that is superimposed regularly of the curved surface of box, bowl, dish.In addition, adopt Mold Making tableware of the present utility model, the paper board material of selecting for use, can expand to and use herb slurry white board, herb slurry composite sheet, and then also can use yellow plate paper from using two-sided white board, like this, just greatly reduce production cost and enlarge the raw material source.
