Abstract
The present invention relates to a method and an apparatus for making a pencil with waste plastic, which is characterized in that components of pencil cores, penholders and fusible plastic of pencil skins are injected in a mould by using the pencil cores, the penholders and an injection moulding machine for the pencil skins, pencils are cooled in a cooling tank and are towed to a cutting machine by a traction engine to be cut off, and every 12 pencils are packed in a box to be put in a warehouse for sale. The present invention has the advantages that waste plastic is recycled, the waste of raw materials and the environment pollution are avoided, simultaneously the pencils have machinability as better wood pencils in this way, the defect that the easy break of lead cords of the wood pencils is overcome, the service life of the pencils is long, the pencil cores, the penholders and the pencil skins for making plastic pencils can be completed at a time, the manpower is saved, the cost is reduced, simultaneously the production is greatly increased, automatic production can be realized, the cost of each pencil is greatly decreased, the pencils are easy to popularize, the make is simple and is easy to realize, and the pencils have no poison and have no effect on the health of a primary scholar when contained in the mouth.
Description
Technical field
The present invention relates to writing implement articles for use technical field, specifically a kind of method of utilizing waste plastics to make pencil.
Background technology
Everybody knows that pencil is first instrument of study, and ten years of study by the cold window starts to walk from pencil.Well imagine the popularity and the importance of pencil, the formation of pencil mainly is to be combined to form by timber and lead for retractable pencil.Along with the mankind's development, along with the importance of environmental protection, cut down in a large number timber be used to do pencil be impossible.Lose money labor life and make pencil,, be prone to defect such as the disconnected core of core shift when cutting because scabbing of assorted tree is many with general trees.And fall trees in a large number and not only bring a large amount of natural disasters to the mankind.A long tree by 30 years amputates it and also can only produce 3-4 ten thousand pencils.Real handy pencil must lean on rare precious linden, and not only raw material are hard-earned for this, and its production cost is also high, and relying on linden to produce pencil is can not satisfy whole necessary for human far away.
Not only China is many to leave waste plastics, plastic film not on the various packings of industry now, agricultural, commodity, medicine and foodstuff behind, and the whole world is found everywhere, and only the mulch film of agriculture aspect and green house of vegetables need, and the whole nation had more than one hundred million tons in 1 year.All turn over and can not ventilate with plant in soil in Xinjiang of China cotton growing area, mulch film year after year.The edge of a field ditch is found everywhere, because the consumption of pencil is big, replace wooden pencil with useless moulding, Chinese invention patent CN1334204.A discloses Lignified plastic pencil and manufacture craft thereof, and the shortcoming of this patent has three: first: consume a large amount of petroleum-based energies and produce plastics, and the non-renewable oil in the world is very nervous, spurt in prices is with the plastics of Petroleum Production, the double in recent years growth of price, with plastics-production pencil cost price height, need a large amount of petroleum-based energy consumption; Second: the price height of plastics, it is compared with waste plastics, the price of plastics will be higher than thousand yuan one ton of waste plastics price 5-6, though this is various for number, the pencil of one-time consumption is to waste one's talent on a petty job, the production cost height, be unfavorable for that market accepts, simultaneously pencil in use the slag foam of the volume of cutting be irretrievable; The the 3rd: the recipe ratio of this patent polystyrene, polypropylene, talcum powder, starch, blowing agent, the starch of this prescription can play the effect to plastic degradation about 3 months, especially there is different smells flying upward in the air, a lot of in addition hand lotions all contain glycerine, thereby plastics, starch, glycerine and the gas that adapts mixes, and that will be to degrade sooner to pencil.Pencil is packed warehouse-in from producing to, is transported to the wholesale stock in strange land,, the minimum turnover period of also wanting half a year, continues to make a complete pencil be degraded into incomplete commodity in the degraded at starch like this from the retailer to student's hand.
Summary of the invention
The objective of the invention is to design a kind of present waste plastic, go to utilize the method for making pencil again.
A kind of method of utilizing waste plastics to make pencil of the present invention is as follows:
1, the waste plastic that reclaims clean, the airing of classifying as required;
2, each waste plastics is put into plastic regeneration pelletizer and be processed into standard particle, classify and pile up;
3, at first prepare burden by the requirement of pencil-lead weight percentages:
Graphite powder: 30-75 calcium stearate: 6-14
Stearic amide: 1-8 benzene alkene: remainder
4, prepare burden by the requirement of pencil shaft weight percentages:
Polyphenyl alkene: 15-40 polyethylene: 20-50
Talcum powder: 30-60 blowing agent: remainder
5, prepare burden by the requirement of pencil epidermis weight percentages:
Polyphenyl alkene: 80-98 pigment: 1-10
Cornstarch: remainder
6, the material that the component of pencil-lead, pencil shaft, pencil epidermis is prepared is contained in respectively in the barrel of injector, pencil-lead, and pencil shaft, the batching of pencil epidermis fusion temperature in injection machine is more than 160 ℃;
7, at first start the injection machine of pen core, after pen core outpours, put into the mould of injection penholder with the hand traction, pen core moves one and opens circuit after the journey in the penholder mould, beginning penholder injection machine starts, pencil outpours, the pencil that outpours runs in the pencil epidermis injection molding automatically, the motion stretch, then pencil epidermis injection machine starts, and the pencil that epidermis has been showed signs of anger moves in the water cooling pond and cools off, and the pencil after the sclerosis is put on the hauling machine again, move to cutting machine forward, full-length in accordance with regulations cuts into the pencil finished product;
8, pin is packed, put in storage, treats to the pencil finished product by 12 in every box.
A kind of advantage of utilizing waste plastics to make the method for pencil of the present invention is: can make the waste plastics recycling utilization, avoid the waste and the environmental pollution of raw material, simultaneously like this pencil is the same with Wood pencil preferably has a machinability, overcome the easily broken shortcoming of Wood pencil lead for retractable pencil, make the long service life of pencil, make the pen core of plastic pencil, penholder, epidermis is disposable finishes, than wooden pencil, the production of paper-holder pencil and operation sequence will be lacked 14 procedures, have saved manpower, have reduced expense, output improves greatly simultaneously, can realize automated production, the price of every pencil reduces greatly, is easy to popularize, promote.The characteristics of this kind plastic pencil maximum are that the component raw material type is few, make to be simple and easy to, and nontoxic, the pupil is contained in the mouth healthy not influence.
