Description
Technical field
The present invention relates to a kind of production equipment and production technology of paper matrix goods, relate in particular to a kind of paper matrix production and copy base equipment and use this equipment to copy the technology of base.
Background technology
With the annual herb string is the moulded paper pulp product that main raw material is made, the health of modern society, convenient, fast, healthy life requirement have been adapted to, can degrade fully with its practicality, after nontoxic, discarded, the characteristics of back to nature have wide development prospect.Thereby paper mould already is a kind of environmental protection industry that helps social economy's sustainable development.The paper mould of China already is started in the eighties of last century the eighties, grows up in the nineties, and the moulding process of its goods, process technology also have many places that demand perfection urgently, improve.In the production of moulded paper pulp product, after slurries prepared, first procedure was exactly vacuum suction, manufacturing paper with pulp becomes to wet the blank process of copying of base, and then thermocompression forming, cross cutting sterilization, packing warehouse-in.Vacuum suction, become the to wet operation of base of manufacturing paper with pulp are inhaled in the mould in link to each other with the negative pressure of vacuum extract system a vacuum and are carried out, the mold cavity surface of inhaling mould in vacuum is provided with the layer of metal silk screen, the passage inside and outside the cavity surface position of vacuum suction mould evenly is provided with many perforation die cavities.The string that is in suspended state is in a large number arranged in the slurries that prepare, when slurries flow through woven wire under the negative pressure of vacuum effect suction of vacuum suction mould bottom, string wherein is by the woven wire detention, string is evenly piled up on the woven wire surface of moulding, twine mutually and lead, form wet base, and then in type wet base is broken away from woven wire, finish and copy the base operation, shift to subsequent processing.But, after wet base breaks away from the net mould, also always more or less there is the string of some to be wrapped on the woven wire, along with continuation of producing and the passing of time, fiber can in the place of fibril aggregation, can make the wet base with aftershaping produce defective at the silk screen surface aggregation, even hole occurs and become waste product, have a strong impact on the quality of product.The processing mode to this problem is in the industry at present,, after shifting, subsequent processing or behind the wet base of cyclic production some, pauses a period of time at the wet base of each moulding, flow to the woven wire surface erosion with automated manner or with manual mode with positive pressure water, the string on it is washed away.The problem that this processing mode exists is, when handling, to make to produce and be deadlocked, finish and just can resume production Deng flushing, influence the continuity of production efficiency and production, and its developing result is also undesirable, because the direction of its malleation current flushing is identical with the vacuum draw water (flow) direction, that is identical with the winding orientation of fiber, the difficult lash state of fiber on silk screen that change always also has many fibers and still is wrapped on the woven wire.Thereby can not solve the problem that influences product quality fully.
Summary of the invention
Purpose of the present invention, be for the base equipment of copying that solves prior art and copy base technology and exist string to twine residual problem, and improve the quality of the production efficiency of copying blank process and wet base and provide a kind of paper matrix production to copy base equipment and use this equipment to copy the technology of base.
The technical scheme that the present invention takes is as follows: base equipment is copied in a kind of paper matrix production, comprise the mould platform of being with air entry, the vacuum that seat is located on the mould platform is inhaled mould, inhale mould to vacuum the slurries bucket of slurries and the negative pressure of vacuum extraction sector that links to each other with the air entry of mould platform are provided, the mold cavity surface of inhaling mould in vacuum applies the layer of metal silk screen again, a plurality of passages inside and outside the cavity surface position of vacuum suction mould evenly is provided with the perforation die cavity, inhale formation one inner chamber between mould and the mould platform in vacuum, also comprise a malleation inflatable body, this malleation inflatable body is connected with gas circuit with the air entry of mould platform respectively with the negative pressure of vacuum extraction sector, can inhale mould to the inner chamber of mould platform top and the vacuum that is positioned at the inner chamber top by air entry and be blown into barotropic gas.
Base equipment is copied in above-mentioned paper matrix production, and wherein, described slurries bucket is the slurries frame that is shelved on the vacuum suction mould die body.
Base equipment is copied in above-mentioned paper matrix production, and wherein, described malleation inflatable body comprises air compressor, provides barotropic gas by air compressor.
Base equipment is copied in above-mentioned paper matrix production, and wherein, the barotropic gas of described malleation inflatable body is provided by the discharging gas of the actuating cylinder of reclaimer.
A kind ofly use above-mentioned paper matrix production to copy the technology that base equipment is copied base, this technology is undertaken by following three step cycle:
In the slurries bucket, quantitatively infeed the slurries that configured;
Open the gas circuit of malleation inflatable body, inhale passage on the mould and the slurries of mesh in vacuum is inhaled model cavity of woven wire are sent into the malleation air-flow by the malleation inflatable body through the air entry of mould platform, the inner chamber of mould platform top, vacuum, air-flow is by way of woven wire the time, wash away and get off to bring into slurries remaining in string on the woven wire, simultaneously, enter of the release of the malleation air-flow of slurries, form countless bubbles and the generation eddy current that thereupon breaks, slurries are stirred along with pressure;
Step 3, copy blank molding
Close the gas circuit of malleation inflatable body, open the gas circuit of negative pressure of vacuum extraction sector, the mesh of inhaling passage on the mould and woven wire through the air entry of mould platform, the inner chamber of mould platform top, vacuum by the negative pressure of vacuum extraction sector is inhaled mould to vacuum and is carried out vacuum suction, making most of moisture content in the slurries inhale woven wire on the mould and passage through vacuum flows into inner chamber and is taken away from air entry, make the string in the slurries evenly heap, twine and lead the wet base of formation on woven wire, then in type wet base is broken away from woven wire and shift to subsequent processing.
The above-mentioned base technology of copying, wherein, the time of sending into the malleation air-flow by the malleation inflatable body in the described step 2 is 0.2-1.2 second, the pressure of gas is 0.15-0.85 milli handkerchief.
Paper matrix production of the present invention is copied base equipment owing to set up the malleation inflatable body, make that copying base technology accordingly can adopt metering for slurry, clean net homogenate with copy three step cycle of blank molding and carry out, enter wet next time base and manufacture paper with pulp in the process of moulding in the moulding of manufacturing paper with pulp of wet base each time, the silk screen of vacuum being inhaled on the mould by the malleation inflatable body blows down cleaning, and the slurries that will enter in the vacuum suction model cavity stir, not only solve string and be wrapped in problem on the silk screen, and improved the quality of wet base product greatly, improved production efficiency.
Description of drawings
The structural representation of the critical piece of base equipment is copied in Fig. 1 paper matrix production of the present invention.
The specific embodiment
