Problems solved by technology
[0003] 1. The production process is complicated, the operation is difficult, the production efficiency is low, and it is not suitable for mass production
[0004] 2. Workers are inseparable from the production process, which is time-consuming and labor-intensive. The work burden of workers is relatively large, and the manpower input is relatively large.
[0005] 3. The bonding area between the lead core and the pen holder is small, and the surface is smooth, the friction is small, and the water absorption is poor, resulting in poor adhesion between the lead core and the pen holder.
[0006] 4. The lead core is brittle and has weak shear resistance
[0007] 5. The quality of the product is poor, and the bond between the pen core and the pen holder is not firm

Embodiment Construction
[0031] The invention relates to a heating extrusion pencil forming method. Firstly, lead core, white material and skin are respectively prepared, and then the three are respectively granulated by means of a granulator. After granulation, they are added to the extruder respectively, The machine evenly squeezes the lead core, white material and skin into the mold, so that the pencil is pressed in the mold, and then the finished pencil is obtained after the post-processing process. Specifically include the following processes:
[0032] (1) Lead waste recycling:
[0033] a. Collect waste pencils: buy waste pencils from major garbage dumps, and uniformly stack them in the waste bin through the transport vehicle;
[0034] b. Crushing waste pencils: transport the waste pencils to the large pulverizer in an orderly manner through the feeding mechanism, and pulverize them in the large pulverizer for 1-2 hours;
[0035] c. Put the crushed waste pencils into the sorter, start the elect...

The invention discloses a heating extrusion type pencil molding method. The heating extrusion type pencil molding method includes the following steps that firstly, pencil lead waste is recycled; secondly, a pencil lead is beaten; thirdly, a white material is beaten; fourthly a surface is beaten; fifthly, molding is performed; and sixthly, post-treatment is performed. In order to overcome the defects in the prior art, the brand-new pencil molding technology is researched and developed; firstly, the lead pencil, the white material and the surface are correspondingly prepared, then the lead pencil, the white material and the surface are correspondingly pelletized through a pelletizer, after pelletizing, the lead pencil, the white material and the surface are correspondingly added into an extruding machine, the lead pencil, the white material and the surface are evenly extruded into a mold through the extruding machine, and therefore compression molding is performed in the mold. Compared with the prior art, the method is easy and convenient to operate, the process is simple, the heating extrusion type pencil molding method is suitable for large-batch production, and the production efficiency is remarkably improved.
Description
technical field [0001] The invention relates to the field of pencil production, in particular to a heating extrusion pencil forming method. Background technique [0002] Pencil is a kind of cultural school supplies commonly used by people. In today's writing pens, pencil is the largest and most widely used pen. The existing pencil production process mainly includes: baking board-planing-grooving-gluing-planing rod-painting-printing-cutting-sharpening-packaging. In actual production, it is found that there are many disadvantages in the traditional pencil production process: [0003] 1. The production process is complicated, the operation is difficult, the production efficiency is low, and it is not suitable for mass production. [0004] 2. Workers are inseparable from the production process, which is time-consuming and labor-intensive. The work burden of the workers is relatively large, and the manpower input is relatively large. [0005] 3. The bonding area between the le...
