Technical Field

[0001] The invention relates to the technical field of bamboo charcoal processing equipment, and in particular to a bamboo charcoal processing and molding equipment and method. Background Art

[0002] In the process of bamboo charcoal processing, a screw rod making machine is usually used to make the crushed bamboo raw materials into regular rods or blocks through an extrusion molding process. The screw rod making machine has technical advantages such as high production efficiency, strong process continuity, wide raw material adaptability and low energy consumption, but its inherent disadvantages cannot be ignored. Specifically, compared with other molding methods, the density of the green body made of bamboo raw materials by the screw rod making machine is relatively small, resulting in a low calorific value of the product, which affects the combustion performance; at the same time, the physical strength of the products molded by the above method is relatively low, and they are easy to break or break during transportation and use, which increases unnecessary losses.

[0003] In addition, during the operation of the screw rod making machine, a cutter is usually used to cut the formed rods into green bodies of uniform size. For example, the invention patent with publication number CN112405641B discloses a batch production device for artificial bamboo charcoal for agricultural use. The cutting process can easily cause deformation of the edges and corners of the green body, especially if the cut surface is not subsequently subjected to corresponding shaping or pressing treatment. The end surface of the dried bamboo charcoal block is not smooth enough and is prone to burrs or debris, which not only affects the appearance quality of the bamboo charcoal product, but also affects the stability and cleanliness of the combustion process due to the mixing of debris in actual use, thereby reducing the user experience.
