Description

Technical Field

[0001] The utility model relates to the technical field of lead core processing, in particular to a lead core drying device for pencil processing. Background Art

[0002] Pencil lead is usually made of a mixture of raw materials such as clay and graphite, and then extruded to form the initial shape of the pencil lead. The extruded lead is relatively soft due to the moisture it contains. In order to remove the moisture in the pencil lead and prevent deformation or quality problems during subsequent processing, it needs to be dried.

[0003] The method of drying pencil leads is usually to use a drum dryer. The staff first puts the lead cores in the core storage tubes (the outer wall of the core storage tubes is provided with multiple evenly distributed air holes), and then places the core storage tubes on the support rods in the drum dryer in turn. Then the drum dryer is started. The heating rod in the drum dryer will evaporate the moisture in the lead core by heating. At the same time, the drum dryer can rotate and drive the lead in the core storage tube to flip over, so as to achieve a uniform drying effect.

[0004] In order to prevent the pencil lead from accidentally falling out of the lead storage tube due to rotation during the drying operation, the staff will cover each lead storage tube in turn before placing it in the drum dryer. When taking out the lead from the lead storage tube after drying, the cover also needs to be opened in turn. Such operation brings labor burden to the staff when taking and placing the lead, and indirectly affects the drying efficiency. To this end, we propose a lead drying device for pencil processing.

[0028] Working principle: During the drying operation, first turn on the drying cylinder 2, and the heating rod in the drying cylinder 2 will generate heat, thereby drying the lead core (this is a well-known prior art and will not be elaborated on). In order to speed up the drying efficiency, the motor 4 on the T-shaped plate 3 can be connected to an external power supply, and the output shaft of the motor 4 will rotate and drive the drying cylinder 2 to rotate on the frame 1, so that the lead core in the drying cylinder 2 can be turned over in the corresponding core storage cylinder 5, thereby achieving uniform drying and accelerating the drying efficiency.

[0029] Before the drying operation is carried out, the lead cores to be dried need to be placed in a plurality of core storage barrels 5 in sequence, and then the plurality of core storage barrels 5 are placed in the drying barrel 2 in sequence. Taking the placement on one group of support columns 8 in the drying barrel 2 as an example, the plurality of core storage barrels 5 are placed between the three support columns 8 from front to back in sequence, and then the cover body 6 is fitted with the front end of the core storage barrel 5 located at the front (in this process, the three U-shaped plates 10 on the cover body 6 will slide backward on the outer walls of the corresponding support columns 8), and then the hand wheel 7 is turned, and the hand wheel 7 will drive the stud 15 to rotate in the inner wall of the tube body 12, and the stud 15 will drive the internal threaded ring 13 to slide backward on the outer wall of the stud 15, and the inner threaded ring 13 will slide backward on the outer wall of the stud 15. The threaded ring 13 will drive the three connecting plates 9 to rotate on the outer wall of the inner threaded ring 13, and the three connecting plates 9 will drive the L-shaped blocks 16 on each of them to slide away from each other in the L-shaped grooves 11 on the corresponding cover bodies 6, and the L-shaped blocks 16 will drive the plug posts 14 on each of them to slide outward in the inner wall of the cover body 6. At this time, the three plug posts 14 will be inserted into the sockets 17 on the corresponding support columns 8, and the cover body 6 can be fixed between the three support columns 8, and the multiple core storage barrels 5 can be fixed between the three support columns 8 and the cover body 6, so as to prevent the lead core from falling from the core storage barrel 5 during the drying operation. Similarly, the remaining core storage barrels 5 can be fixed in the drying barrel 2 according to the same operation, which is easy to operate. After the drying operation is completed, the multiple core storage barrels 5 can be taken out of the drying barrel 2 according to the opposite operation.

[0030] It should be noted that the lead core drying device does not require the staff to cover each core storage tube 5 with a lid before the drying operation, thereby bringing convenience to the staff in taking and placing the lead core, and indirectly improving the drying efficiency of the lead core.
