Description

Environment-friendly materials extrusion shaping machine

Technical field

The utility model is related to environment-friendly materials field of mechanical technique, refers in particular to a kind of environment-friendly materials extrusion shaping machine.

Background technology

Ceramic honey comb is a kind of new ceramics product of structure for developing in the last thirty years like honeycomb shape.By using earliest In kart tail gas clean-up to today is widely used in the industry such as chemical industry, electric power, metallurgy, oil, electronic apparatus, machinery, And more and more extensively, development prospect is considerable.

Ceramic honey comb has the advantage that as filtering material：Chemical stability is good, acid and alkali-resistance and organic solvent；Fabulous is resistance to Rapid heating and cooling performance, operating temperature may be up to 1000 DEG C；Anti-microbial property is good, is difficult by bacterial degradation, is not easily blocked and easily regenerates； Stronger structural stability, pore-size distribution is narrow, and permeability is high；It is nontoxic, it is particularly suited for the treatment of food and medicine.

Ceramic honey comb generally by extrusion shaping machine extrude and formed honeycomb ceramic idiosome, then by high temperature oven toast with Ceramic body is fired into, if the material body skewness in the ceramic honey comb idiosome of extrusion molding, easily produces wall after firing The shortcoming of thickness ununiformity, and the feeding mouth of the shaped device of existing press-forming machine is usually one, and usually extrusion device Extruding embryo block, then directly extruded by shaped device, it is further equal in middle gap not to embryo material between shaping column Even distribution, so as to influence the wall thickness of ceramic honey comb after sintering, and then influences performance, and cellular material idiosome can in conveying Can be stuck in extrusion device due to viscosity, conventional extrusion shaping machine cannot solve this problem.

The content of the invention

Technical problem to be solved in the utility model is：There is provided one kind can uniformly divide embryo material between extrusion and shaping It is equipped with extruded stock body uniformly and to dispensing can force the environment-friendly materials extrusion shaping machine of the ceramic honey comb idiosome of feeding.

The technical scheme in the invention for solving the above technical problem is：A kind of environment-friendly materials extrusion shaping machine, including Frame, being located at central rack is used to the shaped device of forming ceramic idiosome and is located on shaped device squeeze shaped device feed Go out device, it is characterised in that：Forming cavity is provided with the shaped device, is vertically interval with for being molded honeybee in the forming cavity Multiple shaping columns of the honeycomb hole of nest ceramics, the shaping column upper end is interval with to carry out feed to be molded to the gap of shaping column Multiple plup inlets of ceramic honey comb；The extrusion device includes being located at the accommodating cavity for being used for accommodating ceramics embryo block on shaped device, The accommodating cavity is provided with cylinder, and the ejecting rod of cylinder is provided with for by the platen of ceramic embryo block force feed vertically downwards；It is described Dispensing structure is additionally provided between pressurizing unit and shaped device, the dispensing structure includes dispensing chamber, the dispensing chamber and pan feeding Hole passes through multiple dispensing channel connections, first passage that the dispensing passage includes radially outward sequentially being set along forming cavity, the Two the n-th passages of passage ..., the n is the integer less than 10 more than 1, and the length of all dispensing passages is identical, the extrusion dress Put and be provided with and dispensing structure between for embryo material further to be compressed the pressure to reduce bubble between material body space or extruding and discharging body Shrinking structure, the pressure texture includes the extrusion chamber of taper, is vertically provided at Packer screw, the horizontally set of extrusion chamber inner conical In Packer screw upper end and first helical gear circumferentially spacing with Packer screw, the compression motor that is located in frame and it is located at compression It is used to coordinate the second helical gear to drive the first helical gear to rotate with the first helical gear in the rotating shaft of motor.

Compared with prior art, the utility model has the advantage of：Pan feeding is equipped between the gap of all shaping columns Hole, shaped device is uniformly injected into by embryo material, with the uniform ceramic honey comb idiosome of extruded stock body；Extrusion device and shaped device it Between be additionally provided with dispensing structure, dispensing chamber is connected by dispensing passage with plup inlet, and the length of each dispensing passage is consistent so that The distance for passing through that embryo material reaches plup inlet from dispensing chamber is consistent, further such that embryo material is evenly distributed, to ensure the honeybee of extrusion Nest ceramic idiosome uniform wall thickness, sets pressure texture between pressurizing unit and proportioner, compression motor passes through the second helical gear The first helical gear is driven to rotate, the first helical gear drives Packer screw to rotate to be forced downwardly embryo material to feed, to avoid embryo material It is deposited in accommodating cavity, and further side causes that ingredient dispensed is uniform, to ensure the ceramic honey comb idiosome uniform wall thickness of extrusion.

As it is of the present utility model it is a kind of improve, the first passage is provided with the first bending, and the second channel is provided with the Two bendings ..., n-th passage is provided with the n-th bending, the bending angle of the bending angle less than the second bending of first bending Degree, the bending angle of second bending is small less than the bending angle of bending angle ... (n-1)th bending of the 3rd bending In the bending angle of the n-th bending, by the improvement, bending is set on dispensing passage, it is logical from each runner to adjust dispensing The difficulty crossed, because the corresponding plup inlet of first passage is nearest apart from axis, therefore sets the first minimum bending of angle to increase Circulation difficulty, the corresponding plup inlet of the n-th passage is farthest apart from axis, therefore sets the n-th minimum bending of angle to provide minimum Circulation difficulty, by the setting of multiple bendings difference angle further to evenly distribute dispensing, to ensure the ceramic honey comb of extrusion Idiosome uniform wall thickness.

There is a kind of improvement as of the present utility model, the plup inlet is taper wide at the top and narrow at the bottom, by the improvement, Plup inlet plays a part of to extrude dispensing, to reduce the air in dispensing gap or extrusion weighing area.
