Abstract
The invention discloses a method for manufacturing pencils, wherein leaves are removed from harvested eupatorium adenophorum stems, and sifting and sorting are carried out according to the diameters of the eupatorium adenophorum stems; the sifted eupatorium adenophorum stems are parted off according to fixed dimensions; then parted air-dried eupatorium adenophorum stems are soaked in water for 5 to 12 hours or the fresh eupatorium adenophorum stems directly enter the next working procedure; heartwood parts of the water-saturated eupatorium adenophorum stems are removed; then pencil leads are directly embedded in hollow parts of the eupatorium adenophorum stems; the eupatorium adenophorum stems embedded with the pencil leads are dried, so as to lead the eupatorium adenophorum stems to hold the pencil leads; and finally, the dried eupatorium adenophorum stems are processed through grinding and polishing, lacquering, trimming, packing and baling, so as to obtain finished product. The method adopts the eupatorium adenophorum stems as material used for manufacturing the pencils, enables the eupatorium adenophorum stems to swell through water saturation, is convenient to embed the pencil leads, then leads the eupatorium adenophorum stems to hold the pencil leads through air shrinkage during the drying process, and greatly simplifies the production technology of the pencils.
Description
Technical field
The present invention relates to a kind of preparation method of stationery, especially a kind of preparation method of pencil.
Background technology
Pencil is its production technology and never very big variation of shape since invention.Its machining process is: the processing of pencil plate straightens one out and ease out his anxiety log, block, and the evolution saw is separated into wooden unit, after hydrothermal treatment consists, is cut into the pencil plate through lath cutter.The long 184mm of plate, wide 73mm, thick 4.8～5.2mm.Dry and high temperature (130～200 ℃) degenerative treatments through heating (60～120 ℃) makes the pencil plate reach the softening degree that volume is cut that is prone to again.Lead for retractable pencil processing graphite lead for retractable pencil is to prepare by a certain percentage with graphite and clay; After kncading machine, three-roller accent mix; (like HB～3H lead core diameter is 1.80～2.10mm) lead for retractable pencil through pressing the core machine to squeeze out the certain specification size; Through heating (50～150 ℃) dry with high temperature (800～1100 ℃) roasting, make it have certain mechanical strength and hardness, after oil immersion processing and processing.Processing of color lead for retractable pencil and graphite lead for retractable pencil are similar, but need not carry out sintering.Processing method has two kinds: a kind of is after clay, talcum powder, adhesive, colorant, grease and wax etc. are mixed, and through moulding, drying and process, is called mixing method; Another kind is to be squeezed into lead for retractable pencil after china clay, talcum powder, colorant and adhesive etc. are mixed or will to be placed on through the lead for retractable pencil of drying in the wick container, makes it fully absorb grease at a certain temperature and processes, and is called immersion method.It is 4.1～4.2mm that pencil shaft processing uses keyway planer that the pencil plate is planed into thickness; And the frid of the core groove that adapts with lead core diameter arranged; Use adhesive that lead for retractable pencil and pencil plate are glued together then; Heating (50～120 ℃) is processed the white shaft pencil that length is 178～180mm through digging the bar machined after dry 1～8 hour under clamped condition.Decorative appearance processing is painted white shaft pencil and printing ornament, and cuts light, identification marking, the first-class processing of dress rubber, it is become have certain specification, the finished product pencil of appearance color and floral designs.Present pencil shaft material mainly is to be main with timber, and adopts timber very complicated as the processing mode of pencil shaft, and production cost is higher.
Summary of the invention
The objective of the invention is: a kind of preparation method of pencil is provided, and its mode of production is simple, and material source is extensive, and with low cost, to overcome the deficiency of prior art.
The present invention is achieved in that the preparation method of pencil, it is characterized in that: with the Eupatorium adenophorum cane defoliation of gathering, carry out sifting sort according to the diameter of Eupatorium adenophorum stem stalk; The Eupatorium adenophorum stem stalk that screening is good is cut by fixed dimension; The air-dry Eupatorium adenophorum stem stalk that again branch is cut was soaked in water 5～12 hours or fresh Eupatorium adenophorum stem stalk is directly got into subsequent processing; The heartwood of the Eupatorium adenophorum stem stalk of full water is partly sloughed, form the Eupatorium adenophorum stem stalk of hollow; Again lead for retractable pencil is directly implanted in the hollow space of Eupatorium adenophorum stem stalk; The Eupatorium adenophorum stem stalk that to implant lead for retractable pencil then carries out drying, makes Eupatorium adenophorum stem stalk clasp lead for retractable pencil; With after dried Eupatorium adenophorum stem stalk process sanding and polishing, japanning, arrangement, packing and the packing, promptly obtain finished product at last.
It is 100 ℃～280 ℃ that the Eupatorium adenophorum stem stalk of having implanted lead for retractable pencil is carried out dry temperature, and the time is 5～30 minutes, or the water content of employing natural air drying to Eupatorium adenophorum stem stalk is below 12%.
Eupatorium adenophorum (Crofton Weed), perennial herb or undershrub." killer " in the plant kingdom, not even a blade of grass grows in the place of arrival, and cattle and sheep poison.Can carry out generative propagation and vegetative propagation, extremely strong to the adaptability of environment, no matter at arid barren barren hill unoccupied place, the top of a wall, Yan Kan, in crack of stone, also can grow.Overgrowed behind the Southwest China great drought in 2010 and to spread, threaten the growth of crops.Eupatorium adenophorum is a harmful organism, does not generally have productive value.
The cane dimension pipe of Eupatorium adenophorum is grown and is possessed the pipeline model characteristic; Its underpart branch comes off owing to the illumination deficiency is withered gradually, and the pipeline that connects these leaves then remains in the cane, and discarded pipeline accumulates in cane down gradually; Form the heartwood part in the cane; Loose or the hollow of this part, the speciality of utilizing this part conveniently to slough of the present invention is replaced heartwood with lead for retractable pencil.In the water saturation process of producing, Eupatorium adenophorum stem stalk can expand, and its air-dry stem stalk external diameter expansion rate can reach 32.22 ± 3.39%, and the longitudinal dilatation rate is merely 0.38 ± 0.12%; And the expansion rate of core part can reach 37.24 ± 8.12%, and its diameter can reach 3.02 ± 0.13mm after the core demi-inflation, greater than the diameter 2.08mm of common lead for retractable pencil; Can be easy to punch with card punch this moment and slough the core in the stem stalk, form hollow stem stalk; To slough the hollow stem stalk of core again and in time implant lead for retractable pencil; The Eupatorium adenophorum stem stalk typing that to implant lead for retractable pencil then is dry; Very low owing to the vertical contract with dry rate of stem stalk in dry run; And radially contract with dry rate is very high, and the diameter of air-dry back core part can reach 1.67 ± 0.14mm, and the diameter of common lead for retractable pencil is 2.08mm; Eupatorium adenophorum stem stalk radial contraction forms good clasping to lead for retractable pencil in dry run.
Owing to adopt above-mentioned technical scheme, compared with prior art, the present invention adopts the Eupatorium adenophorum cane as the material of making pencil shaft; Slough the core part after utilizing water saturation that the Eupatorium adenophorum cane is expanded, the convenient lead for retractable pencil of implanting makes Eupatorium adenophorum cane drying shrinkage clasp lead for retractable pencil through drying again; Thereby simplified the production technology of pencil greatly, the present invention has made full use of Eupatorium adenophorum, has played the effect of turning waste into wealth; Practice thrift timber, reduced environmental pressure.The inventive method is simple, and material source is extensive, low production cost, and result of use is good.
