Pencil board softening and modifying device

Abstract

The invention discloses a pencil board softening and modifying device, and belongs to the field of pencil production equipment. The pencil board softening and modifying device comprises a pencil boardconveying box and a softening and modifying pool, and heating nets are respectively arranged on two sides of the softening and modifying pool; the pencil board conveying box is placed in the softening and modifying pool, and a pencil board groove which is through left and right is formed in the pencil board conveying box; in the hydrothermal softening process, liquid can be added into the softening and modifying pool; in the drying and high-temperature denaturation process, liquid in the softening and modifying pool can be discharged, gas is introduced into the softening and modifying pool, in the whole process, the pencil board is always located in the high-temperature environment of the softening and modifying pool, great cooling is avoided, and thus bending or embrittlement is not likely to happen, and staged temperature rising is not needed in the drying process; the problems in the prior art that in order to prevent the pencil board from being bent or embrittled, the pencil boardneeds to be heated in a staged mode when the pencil board is dried, consequently, time consumed in the machining process is too long, and the cost is greatly increased are solved.

Description

technical field [0001] The invention relates to a device for producing pencils, in particular to a pencil board softening and modifying device. Background technique [0002] The pencil board is a semi-finished product in the pencil production process, which can be made into a pencil shaft after being divided and processed; the pencil board needs to undergo hydrothermal softening, drying, high-temperature denaturation and other processes before cutting to ensure that the pencil board is softened and easy to cut degree. And existing pencil board is in the processing process, and the softening of pencil board, drying, high-temperature denaturation process are separated, and in the transportation process of pencil board cooking pool to drying furnace, the temperature of pencil board can reduce, and in drying furnace temperature After the continuous rise, the pencil board is prone to bending and embrittlement, which leads to easy fracture of the pencil board during cutting, resu...
