Fig. 1 to 8 show an embodiment of the present invention. This embodiment provides a pencil lead drying device. The apparatus comprises a box 100, the box 100 comprising a frame 101 and steel plate side walls welded to the frame 101. The middle of the frame 101 is provided with a cross beam. The side wall of the box body 100 is provided with a box opening 102, a box door 103 hinged with the frame 101 is arranged at the box opening 102, and the top wall of the box body 100 is provided with a plurality of ventilation holes 104. The inner wall of the box body 100 is provided with an explosion-proof electric heating device such as an electric heating rod. Inside the cabinet 100 is a horizontally disposed rotatable bracket 300.

As shown in fig. 2 and 3, the bracket 300 includes a main shaft 301, and both ends of the main shaft 301 are respectively bearing-connected to the bearing housings 500. The bearing housing 500 is bolted to the cross beam of the frame 101. Two circular connecting plates 303 are welded to the part of the main shaft 301 located between the two bearing seats 500, and a plurality of carrying baskets 600 are radially welded around the main shaft 301 between the two connecting plates 303, that is, two side plates 607 of the carrying baskets 600 are respectively welded to the two connecting plates 303. In order to make the structure of the bracket 300 more stable, a rib plate 304 is welded between two adjacent carrying baskets 600, the rib plate 304 is welded at two ends of the carrying baskets 600, but the rib plate 304 may be welded at other positions between the two carrying baskets 600. One end of the main shaft 301 extends out of the bearing seat 500 and is provided with a second belt pulley 302, and the second belt pulley 302 is connected with a first belt pulley 202 on an output shaft 201 of the motor 200 through a belt 400. Wherein the diameter of the second belt pulley 302 is larger than that of the first belt pulley 201, thereby playing a role of speed reduction. The motor 200 is bolted to the floor, but the motor 200 may be bolted to the case 100.

The carrying basket 600 shown in fig. 5 to 7 has a rectangular parallelepiped shape, and a plurality of cartridge cases 700 are placed therein. The carrying basket 600 includes U-shaped side plates 607 at both ends, a bottom plate 606 connecting the two side plates 607 by welding, and a basket cover 601 disposed opposite to the bottom plate 606. Wherein the side plate 607 is welded with the connecting plate 303 and the bottom plate 606 faces the main shaft 301. The upper and lower parts of the bearing basket 600 are groined cover plates which are vertically welded by a plurality of transverse supporting plates 602 and T-shaped steel 603. The cover plate is welded to the side plate 607 and the bottom plate 606. The T-section steel of the two cover plates divides the inner space of the carrying basket 600 into a plurality of accommodating spaces for accommodating the cylindrical refill cartridges 700. The distance between two adjacent T-shaped steels 603 or the distance between the T-shaped steel 603 and the side plate 607 is matched with the height of the refill barrel, and the distance between the upper cover plate and the lower cover plate, namely the height of the bearing basket is matched with the diameter of the refill barrel 700, so that the refill barrel 700 can be freely taken out or put into the bearing basket without large swing. The upper end box opening of the refill cartridge 700 is sealed at the bottom, and a plurality of through holes 701 are formed in the side wall. The basket cover 601 is hinged with a transverse supporting plate 602 of the lower cover plate through two hinges 605, two grooves are formed in the side edge, away from the hinges 605, of the basket cover 601, the transverse supporting plate 602 of the upper cover plate is hinged with a hinge bolt 604 matched with the grooves, and a butterfly nut is screwed on the hinge bolt 604.

It should be noted that the T-shaped steel 603 may be replaced by a common steel plate, and the U-shaped side plate 607 may be replaced by a common steel plate, as long as the size of the bearing frame 600 enables the plurality of pen core cylinders 700 not to move or rotate uncontrollably in the bearing frame 600, and more than two pen core cylinders may be welded in a row, so as to further improve the stability of the pen core cylinders 700 in the drying process.

When the pencil lead box is used, the box door 103 is opened, the butterfly nut is rotated to open the basket cover 601, the pencil lead barrel 700 is taken out, a pencil lead is placed into the pencil lead barrel 700, the pencil lead barrel 700 is placed into the bearing basket 600, and the butterfly nut is rotated to lock the basket cover 601. The lid 101 is then closed and the motor 200 and electric heater are activated. The motor 200 drives the bracket 300 to rotate for drying. During the drying process, the rotation of the bracket 300 plays a role of promoting air circulation, and the cartridge 700 does not rotate or move under the mutual restriction of the T-section steel 603, the side plate 607, the bottom plate 606, the basket cover 601 and the adjacent cartridge 700. The pencil leads collide, extrude and rub with each other in the pencil lead barrel 700, so that the pencil leads can be straightened while being dried; pencil leads that are not aligned or have quality defects break down during the impact and leak out of the through hole 701, thereby completing the pencil lead screening.
