Abstract

A technology for manufacturing pencil with straw or stalk includes such steps as mixing pulverized straw or stalk, adhesive and edible salt, die pressing, cutting to needed length, installing lead, sterilizing, baking, polishing, and colouring. Its advantages are no need of wood, and low cost.

Description

A kind of preparation method of straw pencil

The present invention relates to the pencil manufacturing technology, a kind of more precisely method of making pencil of straw.

The penholder major part of the pencil parcel pen core on the market is to make with wood raw material now.As everyone knows, timber is the precious resources of country, also is material in short supply, and how all trades and professions all save timber in research, seek substitute for wood, and the annual amount of wood that is used to make pencil is also considerable, therefore, also intentionally will study substitute for wood.

The objective of the invention is to propose a kind of preparation method of straw pencil of cheap, alternative timber.

Realize the main technical schemes of the object of the invention:, promptly make required pencil by steps such as extruding, moulding, cutting, dress pen core, sterilization, oven dry, polishing, polishing, colourings with straw, adhesive and salt mixing.

The preparation method of straw pencil of the present invention may further comprise the steps:

(1) will go root, clean with the straw of leaf and be crushed to the 80-100 order slightly;

(2) get stalk 75-85 part after step (1) is pulverized and binding agent 8-14 part, salt 0.1-0.2 part, put into container and stir, obtain compound, above-mentioned umber is parts by weight;

(3) the compound input staged stalk processing extruder with step (2) is extruded into strip, shape the machine moulding through multifunction straw again, make cross section and comprise circle, hexagon and the hollow blank that is complementary with pen core, cut into the length of pencil commonly used again, insert pen core then, air dry at room temperature obtains the pencil blank, 50-60 ℃ of described extruder and forming machine operating temperature, pressure 4-5kg/cm ²

(4) step (3) pencil blank is through microwave method sterilization, oven dry commonly used, and polishing at last, polish, paint to handle is required product.

Plant straw of the present invention comprises table stalk, rice straw, cornstalk, cotton stalk.

Binding agent of the present invention is directly to wear into as corn steep liquor, pachyrhizus slurry, potato slurry cleaning the amyloid fruit gross weight band meat that comprises corn, pachyrhizus, potato that need not to dry, and directly is added in the stalk to get final product.

Staged stalk formula extruder of the present invention and the multifunction straw machine of shaping are patented products, and the patent No. is respectively 9924726.1,9924351.2.The shape that described forming machine is extruded is that the model that designs is as requested determined, is circular, hexagon as the common cross section of pencil holder.

Advantage of the present invention:

The cost of material that method of the present invention is used is cheap, and is with discarded straw, is alternative timber through simple processing, and the pencil that is used to make reflects fine after the student is on probation at large; Primary raw material stalk of the present invention, binding agent all are natural plants, are easy to separate and fall, and the pen bits do not pollute the environment; Used equipment of the present invention all is known patented products, and the method for making pencil is very simple, and technology is easy to promote, and therefore, method of the present invention has important economic implications and social effect.

Example 1

Will 78 kilograms cornstalk, 10 kilograms wet corn powder, the salt mixing input staged stalk processing extruder of 0.15Kg after the pulverizing be extruded into strip, shape machine through multifunction straw again, make circular hollow blank, cut, insert pen core again, air dry, after microwave sterilization, oven dry, sanding and polishing, colouring handle and promptly obtain required product.

Example 2

The raw material rice bar 85kg of this example, 13 kilograms in potato slurry, 0.18 kilogram of salt, preparation method is with example 1.

Claims
