Description

Paper pulp moulded tableware automatic moulding machine

Technical field

The utility model relates to compression molding, is a kind of paper pulp moulded tableware automatic moulding machine.

Background technology

At present, paper mould device fabrication industry belongs to an emerging industry, new environmental protection project both at home and abroad.It is to be signed as according to international " Montreal Agreement " various countries to eliminate disposable foamed plastic, is that first-selection substitutes disposable foamed plastic food and drink tool and industrial goods liner with the paper mould worldwidely.

Paper pulp mould equipment manufacturing technology all is the production of finishing goods on the basis of four moulds location both at home and abroad.(a secondary shaping punch-die, a secondary typing convex-concave hot-die).External equipment: as like to be beautiful beautiful company, Iceland happiness Fu Deng company, Japanese Yi Tengzhong company of Canada all are four moulds location, no matter adopt rotary drum or the mode of once finalizing the design, and all are within four mould orientation ranges.Which kind of mechanical type no matter domestic production manufacturer production semi-automatic or automatic adopt, all within this scope.Its weak point mainly contains: 1, the protruding cold mould of moulding is under the state of vacuum suction filter, paper pulp molding ground paper moisture reaches ± and 80%, the moisture of the recessed cold mould of moulding after extruding also is not less than 70-74%, run to shaping and drying on the hot-die then, time could dry goods about 150-180 greatly second, yields poorly.2, when recessed cold mould is transferred to protruding hot-die with ground paper, when down ground paper being blown on the protruding hot-die, be easy to dislocation.(because of moisture is too high, the moulding ground paper is too soft, and contraposition is inaccurate) percent defective height, yield rate is at 50-70%.3, existing four mould positioning process, not only device fabrication complexity, and in design automation equipment, link is many more, increases maintenance cost, and increase appreciable manufacturing cost in succession for manufacturer.(increasing cylinder, electromagnetic valve, mould, template and other auxiliary material) more.4, formation mould is in running, and needs were changed or washed in 3-5 days, is primarily aimed in the mould air flue of vacuum suction filter to be stopped up by fine fibre and incrustation scale, can not work long hours.(at present, to cold mould boring of moulding and air flue, mechanical processing technique is limited, causes causing in a short time air flue to stop up).All adopt the discontinuity high pressure washing at present both at home and abroad.5, the typing heating problems now generally with after the Mold Making, is installed on the heating plate, and conducting heat with heating plate just to reach the purpose of oven dry.But the continuous drying goods are difficulty relatively, 25-40 ℃ of 4-5 cycle mold temperature decline, and reason is that the thermal compensation ability does not reach, and does not accomplish the present situation of continuous operation.The present situation of 6, four moulds location, the rule of production of articles generally are to adopt the nethike embrane moulding, and nethike embrane shifts, and the state of light outer net in the goods is accomplished in the nethike embrane typing, can't resolve the user will be on the goods outer wall color printing and do advertising and printing.

Summary of the invention

The purpose of this utility model is to provide a kind of paper pulp moulded tableware automatic moulding machine, adopt three mould location technologies, solved the protruding cold mould of moulding under the state behind the vacuum suction filter, by the direct extrusion modling of recessed hot-die, rerun the hot-die shaping and drying, the ground paper moisture is low, and drying time is short, and output improves 2.5-3 doubly.

For reaching above-mentioned purpose, paper pulp moulded tableware automatic moulding machine of the present utility model, be made up of frame, mounting plate, stock tank lifting platform, a sleeve forming punch and a secondary typing punch-die, electrical equipment control part, guide rail, cylinder support, manipulator etc., be characterized in: frame and mounting plate are welded to form a body; Guide rail is installed above body, and Impactor respectively is equipped with at the guide rail two ends, and a cylinder is installed in the body upper left side by the cylinder support, and an end of a connecting rod is connected with the motion template of typing die, and the other end is connected with the cylinder of typing punch; Forming convax mould and typing punch-die are installed in respectively on separately the baffle plate; Described manipulator is made up of connecting rod, cylinder, flange, vacuum (-tight) housing, pole, sucker.Behind the above-mentioned three moulds location, forming convax mould is under the state behind the vacuum suction filter, by the direct extrusion modling of hot die, seesaw by aggregate motions such as guide rail, Impactor, cylinder and the typing of typing punch by typing die and manipulator again, finished the goods of food and drink tool.

Paper pulp moulded tableware automatic moulding machine of the present utility model, adopt three mould jigs, have following superior effect: 1, adopt three mould location technologies, solved the protruding cold mould of moulding under the state behind the vacuum suction filter, after the direct extrusion modling of recessed hot-die, the moisture of moulding ground paper runs to the hot-die shaping and drying then ± 50%, (oven dry add thermal recovery three-dimensional heating) drying time 35-45 second, be more than 3 times of four moulds location, output is original 2.5-3 times.2, because die hot pressing is shifted, directly on protruding hot-die, carry out shaping and drying, not only do not have the goods dislocation, and the goods yield rate is significantly improved.The yield rate of four moulds location is at 50-70%, and the yield rate of three moulds location is more than 95%.Three mould location technologies are in paper pulp mould device fabrication process, and the advantage with the simplification of equipment, low cost, low energy consumption, high production has overcome complicated link and expensive output in the existing device fabrication.3, adopt the form of three moulds location, at first when shifting ground paper, cold base has been pushed and heated, the moisture of ground paper is stabilized in ± 50%, saved the time, shortened the production of articles cycle.4, formation mould adopts special process and material, does not need special processing technology, makes pore, and airway surface is smooth, does not stay fiber and incrustation scale when vacuum suction filter.Need not change or wash mould, solve the loaded down with trivial details work of frequent replacing or flushing mould, improve the output of goods.5, successfully grasped temperature control technology (error is in ± 3 ℃ of temperature controlling range), thermal compensation is stable and reliable for performance, and is safe in utilization.6, the drive manner that adopts three mould jigs is with protruding cold net mould vacuum suction filter base, is shifted combining typing with protruding hot optical mode by recessed hot optical mode, the requirement that goods is reached please both parties, and can on the outer wall of goods, carry out color printing and make the usefulness of advertisement.
