Pencil grooving machine

Abstract

A pencil grooving machine comprises a frame, the frame is provided with a slideway for sliding of a pencil plate, the slideway is divided into an inclined slideway at the entrance segment and a straight slideway at the chipping segment; the inclined slideway is provided with a conveying belt; a pair of touching switches are arranged at a horizontal interval at the inner side of the entrance point of the straight slideway; a limit plate is fixedly arranged on the straight slideway above the entrance point of the straight slideway; an elastic barrier sheet is arranged at the outer side of the entrance point of the straight slideway; a grooving cutter rack and a face-planing cutter rack are successively arranged above the straight slideway; a conveying roll is installed at the side of the grooving blade race and the face-planing cutter rack and connected with a conveying motor; the grooving cutter rack and the face-planing cutter rack are respectively installed on the output shafts of a grooving motor and a face-planing motor; the grooving motor is installed on an elevating bench connected with the touching switch; the grooving cutter rack is provided with a grooving cutter and a gravity-center balancing block symmetrical with the grooving cutter along a rotation shaft; and the grooving cutter is provided with arc blades which are protruded outward and arranged at intervals, and a straight blade is arranged between two adjacent arc blades.

Description

technical field [0001] The invention relates to a pencil processing device, in particular to a pencil groover for making grooves on a wooden board for making pencils. Background technique [0002] The pencil mainly includes a pen holder and a pen core. The pen holder is generally made of wood. There is a through hole for storing the pen core in the middle of the pen holder. This through hole is a slender structure, and it is very difficult to punch through the hole. Therefore, when making the pen holder, it is first made by bonding two wooden boards. There are multiple grooves distributed at intervals on the two boards. , and cut the glued boards into the required pencils. Therefore, when processing wood boards, the end faces that are bonded to each other need to be very smooth, and there are many slender grooves that need to be opened on the end faces. The grooves ensure uniform size, smooth surface, and high precision requirements. For example, the pencil grooving device...

[0003] And for the through hole on the penholder, the upper end is closed and the lower end is open, so that the pen core will not slide out from the upper end in the penholder, so the position of the planing groove on the pencil board depends on the through hole. Figure 9 In the pencil board 16, one end of its groove 16-1 runs through one end of the pencil board, and the other end is located in the pencil board, so that the planer cannot directly penetrate the pencil board when planing the pencil board, so the above-mentioned pencil grooving device is difficult. Processing the pencil board increases the difficulty of grooving and reduces production efficiency, and currently there is no equipment suitable for rapid processing of the pencil board with this structure
