Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pencil lead processing, in particular to a processing device for colored pencil leads. Background Art
[0002] Lead, the core of a pencil, is primarily made from a mixture of powdered graphite and a binder. Colored lead is a product that incorporates pigments. The production process involves mixing the graphite powder, pigment, and binder, then forming the lead through extrusion or compression. The resulting softer, long, graphite lead strips are then cut to meet production requirements and then dried and hardened to create solid colored lead.
[0003] After the initial cutting, the lead needs to be trimmed again to make the length of the lead consistent with the length of the pencil to be made later. When cutting the lead with the existing cutting device, we found that because the lead is in a relatively soft state, the cut lead is easily carried by the two adjacent cutting knives. The staff needs to manually remove the lead between the two adjacent cutting knives, which not only brings labor burden to the staff, but also indirectly affects the cutting efficiency. At the same time, after cutting the colored lead, the cutting knife is prone to some colored lead debris adhering to the blade. In order to ensure the smooth progress of the subsequent cutting operation, the staff needs to clean the cutting knife one by one, which is not only troublesome to operate but also has certain risks. To this end, we propose a processing device for colored lead. Utility Model Content

[0020] See also Figure 1 In the figure, the lifting assembly includes two L-shaped plates 2, which are fixedly connected to the upper end of the operating table 1 near the edges on both sides, and the lower ends of the horizontal parts of the two L-shaped plates 2 are fixedly connected to electric push rods 3, and the telescopic shaft ends of the two electric push rods 3 are fixedly connected to the upper end of the rectangular plate 4.
[0021] See also Figure 1 and Figure 2 In the figure, two connecting rods 9 are fixedly passed through the inner walls of the multiple cutting knives 8, and the two connecting rods 9 are arranged symmetrically front to back; specifically, the setting of the connecting rods 9 can make the connection between the multiple cutting knives 8 and the rectangular plate 4 more stable.
[0022] See also Figure 1 and Figure 2In the figure, the upper ends of multiple guide columns 11 are fixedly connected to the limit plates 5, and the bottom ends of multiple limit plates 5 are in contact with the upper ends of the rectangular plates 4; specifically, the setting of the limit plates 5 can prevent the guide columns 11 from slipping off the inner wall of the rectangular plate 4.
[0023] See also Figure 4 and Figure 5 In the figure, the guide mechanism includes a T-shaped block 15 and a T-shaped slot 16. The T-shaped block 15 is fixedly connected to the middle of the bottom end of the long plate 6.

[0025] Working principle: First, place the lead core on the operating table 1, and then connect the electric push rods 3 on each of the two L-shaped plates 2 to the external power supply. The telescopic shafts of the two electric push rods 3 will move downward and jointly drive the rectangular plate 4 to move downward. The rectangular plate 4 will drive multiple cutting knives 8 to move downward, thereby completing the cutting of the lead core. During the cutting process, multiple pressing plates 10 will all contact the lead core. As the rectangular plate 4 continues to move downward, the two guide columns 11 on each of the multiple pressing plates 10 will all slide upward in the inner wall of the rectangular plate 4 (in this process, the multiple springs 12 between the rectangular plate 4 and the pressing plate 10 will all be squeezed on the outer walls of their corresponding guide columns 11). When the cutting is completed, under the action of the multiple springs 12, the multiple pressing plates 10 will automatically reset, thereby pushing the lead core stuck between the two cutting knives 8 onto the operating table 1.
[0026] When the blade of the cutting knife 8 needs to be cleaned, it is only necessary to push the long plate 6 forward, and the long plate 6 will slide forward on the upper end of the connecting plate 13 (in this process, the T-shaped block 15 on the long plate 6 will slide forward in the T-shaped groove 16 on the connecting plate 13). The long plate 6 will drive the multiple V-shaped scrapers 7 to move forward, and the multiple V-shaped scrapers 7 will slide forward along the lower ends of their respective corresponding cutting knives 8, thereby scraping off the lead core debris adhering to the blade of the cutting knife 8. The operation is simple.
[0027] It should be noted that the present device can prevent the cut lead from being carried away by the two adjacent cutting knives 8, eliminating the need for staff to manually remove the lead between the two adjacent cutting knives 8, thereby reducing the labor burden of the staff and indirectly improving the cutting efficiency. At the same time, the lead debris adhering to the blade of the cutting knife 8 can be easily removed without the need for staff to clean the cutting knives 8 one by one, which not only simplifies the operation but also reduces certain risks.
