The invention relates to the field of cigarette production, in particular to a novel cigarette production method applying a 3D (3-dimensional) printing technology. A novel cigarette comprises a cigarette stick and a filter tip stick, wherein the cigarette stick is formed by bonding tobacco powder ground by tobacco leaves through an adhesive. The production method of the novel cigarette provided by the invention comprises the following steps: producing the cigarette by utilizing the 3D printing technology, increasing the tobacco powder layer by layer in hierarchical processing and superstition solidification forming ways to generate a 3D entity cigarette, spraying the adhesive through a 3D printer according to the shape of each cross section designed in software, carrying out progression layer by layer and finally obtaining the cigarette stick which is formed by overlapping all the cross sections, so that the production precision is effectively ensured. Meanwhile, the treatment process of the tobacco leaves is simplified, the application scope of tobacco raw materials is broadened, the utilization rare of the tobacco raw materials is improved, and the wood gas of cigarette smoke is removed. The 3D printer used in the novel cigarette production method is smaller in size and is more economic, the relevant procedure of computer graphic data can be directly utilized to generate the cigarette, and the cost is saved while the production is convenient.

The invention discloses a modular assembly type L-shaped cold-formed thin-walled steel combined wall and a connecting mode of the modular assembly type L-shaped cold-formed thin-walled steel combined wall. The modular assembly type L-shaped cold-formed thin-walled steel combined wall is characterized in that the middle part of an L-shaped cold-formed thin-walled steel framework is filled with a heat preservation layer; a wall panel and the L-shaped cold-formed thin-walled steel framework are connected through self-tapping screws; the modular assembly type L-shaped cold-formed thin-walled steel combined wall is formed by the L-shaped cold-formed thin-walled steel framework, the heat preservation layer and the wall panel. Horizontal-direction connection between an L-shaped cold-formed thin-walled steel combined wall module and a common wall module is realized through a horizontal connecting mode between wall modules; vertical-direction connection between two adjacent L-shaped cold-formed thin-walled steel combined wall modules which are adjacent in the vertical direction is realized through a vertical connecting mode between the wall modules. The modular assembly type L-shaped cold-formed thin-walled steel combined wall disclosed by the invention integrates structural bearing and heat preservation, and has the advantages of high integration and assembly degrees, applicability in industrial production and the like, and the problems of weak connection between a longitudinal wall and a horizontal wall, high difficulty and difficulty in handling installation seams, and the like can be solved. The connecting mode of the modular assembly type L-shaped cold-formed thin-walled steel combined wall is simple in structure and is quick and efficient, and a large amount of labor cost can be reduced.

The invention discloses a back elevation clamp of an initial die. The back elevation clamp comprises a turntable tailstock bridge plate structure, self-centering locating and clamping mechanisms and lateral locating mechanisms. A main board of the turntable tailstock bridge plate structure is provided with two sets of self-centering locating and clamping mechanisms, and the lateral locating mechanisms are arranged in front of the self-centering locating and clamping mechanisms. The back elevation clamp has the beneficial effects that one cylinder drives one mechanism, four pressing plates are controlled simultaneously, the die is compressed, and the centering effect is realized, so that the production precision is guaranteed, and the processing yield is improved; operation of processing parts is convenient, adjusting while remodeling is convenient, and the work time is saved; furthermore, the clamp is a double-station clamp, two parts can be processed at a time, processing contents on two faces can be processed at a time through the turntable tailstock bridge plate structure, the cost is reduced, and the processing efficiency is improved.
