This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. Please make the page settings of your word processor to A4 format (21 x 29,7 cm or 8 x 11 inches); with the margins: bottom 1.5 cm (0.59 in) and top 3 cm (1.18 in), right/left margins must be 2 cm (0.78 in).Structural Optimization of the Negative Pressure Regulation Device for the Cigarette Separation Wheel of the ZL29 Filter Rod Forming Machine Based on Fluid Field Finite Element Analysis To conduct structural optimization research on the suction block of the negative pressure regulation device for the cigarette separation wheel of the ZL29 filter rod forming machine for slim cigarettes, improve the quality of finished filter rods, reduce the defect rate of filter rods, minimize equipment downtime, and enhance operational efficiency, this paper employs FLUENT fluid simulation technology to first establish three-dimensional models of three different suction block structures. Subsequently, the internal flow fields of the suction blocks are extracted, and simulation analyses of the flow fields under the same pressure conditions but different structural configurations are conducted. Finally, the results are compared and validated against experimental data. The findings indicate: (1) When the suction block is designed with an innovative structure, the pressure coefficient distribution in the flow field is more uniform, and the suction performance during operation is more stable; (2) When set to a negative pressure suction pressure of 4 bar, particle movement fluctuations within the suction block channels are minimal, and velocity remains stable, making it the optimal structure; (3) Experimental results show that the innovative structure maintains the most stable vinegar rod quality after continuous operation of the molding machine for 1 hour, 2 hours, 3 hours, and 4 hours, with significant improvement effects. After 8 hours of continuous operation, the number of equipment shutdowns is the lowest, and equipment efficiency is the highest
