At present, plastic bottles are mostly adopted for containing medicines, liquids and other objects, although a part of the plastic bottles are recycled, most of the unrecoverable plastic bottles still pollute the environment, the plastic bottles are difficult to degrade, paper bottles are packaging containers for reducing the use of plastics so as to meet the requirement of environmental protection, and at present, the paper bottles adopt two solutions so as to achieve the purpose of reducing the use of plastics;

the first paper bottle scheme is as follows: the paper bottle is formed by assembling the paper container, the plastic liner, the plastic bottle mouth and the plastic bottle cap, and the plastic use can be reduced by 70%;

the second paper bottle scheme is as follows: as shown in the attached figure 1, the paper bottle is formed by bonding a paper container a1 and a plastic bottle opening a2 and combining a plastic bottle cap, and the plastic use can be reduced by 85 percent;

from the above scheme, the problem of not using plastic is not solved completely, and from the market demand, if the environment-friendly requirement of replacing plastic with paper is met, the technical problem of paper-plastic of the bottle mouth and the bottle cap thread is solved, plastic can not be used completely by adopting the paper bottle to integrally form the thread, the production of the plastic bottle mouth and the bottle cap, the processes of dispensing, assembling and the like can be reduced in production, the cost can be reduced, and the problem that the paper bottle does not use plastic is solved;

however, it is found in the production process that the internal and external spiral threads formed by the elastic body are as shown in fig. 2-4, and the part of the inner side of the paper container bottle mouth b corresponding to the external spiral thread b1 is formed by extrusion through the lower mold core of the existing elastic mold and the elastic body d, so that the density of the external spiral thread b1 formed at the paper container bottle mouth b is obviously low; the inner side of the paper bottle cap c is provided with an inner spiral thread c1 formed by extrusion molding through a lower mold core and an elastic body d of the existing mold, and therefore, the section of a spiral groove of the formed inner spiral thread c1 is arc-shaped and has no edges and corners, so that the precision of the inner spiral thread c1 is poor, the production and use standards cannot be met, and the locking force between the inner spiral thread c1 and the outer spiral thread b1 at the position of a paper container bottle opening b is poor; therefore, the internal and external spiral threads formed by extrusion through the existing elastic die have the problems of low density, poor precision, poor locking force and the like, and the problems need to be improved urgently;

Detailed Description

The present invention is further described in detail below with reference to the drawings and examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 5-23, the utility model provides an inside and outside spiral line forming die of integrated into one piece paper mould, include: the paper pulp wet blank extrusion forming device comprises an upper mold core 2 arranged on a first driving part and a lower mold core 3 arranged on a second driving part, wherein a first spiral structure 201 and a second spiral structure 301 which are used for extruding a paper pulp wet blank 1 to form spiral threads are respectively arranged on the upper mold core 2 and the lower mold core 3.

The working principle of the technical scheme is as follows: the spiral line forming die carries out hot press forming on the paper pulp wet blank 1, the paper pulp wet blank 1 comprises a paper bottle container g (containing a paper bottle mouth f) and a paper bottle cap e which are formed by adopting pulp absorption, before the paper bottle container g is placed on the spiral line forming die, the whole paper bottle container g can be integrally formed by adopting an elastic die in the prior art, the elastic die is used for replacing the upper die core 2 with an air bag to extrude the inside of the paper bottle container g, so that the paper bottle container g is preliminarily formed, but the air bag has poor forming effect on the outer spiral line f1 at the paper bottle mouth f, therefore, the paper bottle container g needs to be placed on a station of the spiral line forming die, is positioned by the lower die core 3 and is extruded under the combined action of the lower die core 3 and the upper die core 2 to form the outer spiral line f1 at the paper bottle mouth f;

after the paper bottle cap e is subjected to pulp suction forming, the paper bottle cap e can be directly placed on a station of a spiral thread forming die, positioned by the lower die core 3 and then extruded under the combined action of the lower die core 3 and the upper die core 2 to form an inner spiral thread e1 of the paper bottle cap e;

specifically, the mold opening state of the lower mold core 3 is changed into the mold closing state of the lower mold core 3 through the second driving part, the station is located at the central axis of the lower mold core 3, before the wet pulp blank 1 is placed, the mold opening state of the lower mold core 3 moves towards the outer side far away from the central axis along the horizontal direction, after the wet pulp blank 1 is placed, the lower mold core 3 moves towards the central axis along the horizontal direction to form the mold closing state, so that the inner side of the lower mold core 3 forms a driving force on the wet pulp blank 1, the central axis of the wet pulp blank 1 is superposed with the central axis of the station, the radial positioning of the wet pulp blank 1 is realized, then the first driving part controls the upper mold core 2 in the mold opening state to move in place, the upper mold core 2 is controlled to start to be changed from the mold opening state into the mold closing state, and forms extrusion force on the side surface of the wet pulp blank 1 together with the lower mold core 3, and spiral grains are formed;

here, the upper mold core 2 in the mold-opened state means that the upper mold core 2 does not come into contact with the side surface of the wet pulp blank 1 after moving to the right position, and therefore, does not form an extrusion force to the wet pulp blank 1 together with the lower mold core 3;

because the first spiral structure is arranged on the outer side of the upper mold core 2, if the first spiral structure moves downwards and directly extrudes the wet pulp blank 1, the wet pulp blank 1 is deformed, a spiral line structure cannot be formed, and the two states of the upper mold core 2 are convenient for demoulding the wet pulp blank 1 after spiral lines are formed;

in the extrusion process, the first driving part and the second driving part are matched to control the upper mold core 2 and the lower mold core 3 to work, a first spiral structure on the upper mold core 2 is in contact with the inner side surface of the wet paper pulp blank 1, and a second spiral structure on the lower mold core 3 is in contact with the outer side surface of the wet paper pulp blank 1, so that under the extrusion of the upper mold core 2 and the lower mold core 3, an outer spiral grain f1 is correspondingly formed on the outer side of a paper bottle mouth f or an inner spiral grain e1 is correspondingly formed on the inner side of a paper bottle cap e;
