Although pencil leads, as an important part of writing and drawing tools, the market demand always exists stably, due to the limited industry scale, the research and development and manufacturing of equipment specifically for pencil lead production have not yet formed a mature and large-scale market. At present, in the process of pencil lead production, enterprises are faced with the dilemma of lacking equipment options. There is almost no complete set of formed equipment on the market that can be directly applied to pencil lead production. Each production enterprise has to rely on its own R & D strength to design and manufacture production equipment by itself to meet the production needs;

[0003] After investigation, the publication number: CN212472893U discloses a pencil lead feeding mechanism. In this technology, "a pencil lead feeding mechanism is disclosed, including a lead storage hopper and a lead discharge port at the lower part of the lead storage hopper for discharging leads. There is a core feeding turntable driven by a driving device beside the lead storage hopper. The surface of the core feeding turntable has grooves that can embed leads. There is a core protection plate beside the core feeding turntable. The core protection plate is arc-shaped and its inner side is attached to the core feeding turntable. A feeding chain for conveying plates is arranged below the core feeding turntable" and other technical solutions, and has technical effects such as "by matching the forward speed of the pencil lead plate with the rotation speed of the core feeding turntable, the core feeding turntable and the pencil lead plate can be synchronously output, and the leads can be accurately placed into the grooves of the pencil lead plate, greatly improving the production efficiency and production quality";

[0004] There is a rolling process in the production process of pencil leads. For the feeding part of the raw materials used for pencil leads, a material cart is used to transfer materials. During the feeding process, a shovel is used for manual operation to scoop the materials in the material cart into the hopper before production operations. The labor intensity during the production operation is high. For each batch of materials, workers need to push the material cart to the rolling hopper, resulting in a large physical load.
