Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing primary air separation apparatus in cigarette making and tipping machines struggles to effectively reduce the content of tobacco stems in cut tobacco, leading to issues such as cigarettes exceeding standard weight and being pierced.
Innovation Solution
A cut-stem separating and baffling apparatus with an optimized strut structure, featuring a hanging panel with a reduced baffling area, an inner hexagon adjustment bolt for adjustable baffle positioning, and a position correction spring to stabilize the baffle, is introduced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the height of the cut-stem separating baffle is increased to improve stem separation, then the stem-containing rate in cut tobacco decreases, but the structural complexity and difficulty of adjustment increase
Solution Approach 1:
The baffle height is made adjustable through a dynamic adjustment mechanism involving adjustment bolts and nuts, allowing the system to adapt to different separation requirements without requiring a completely different structure for each height setting
Solution Approach 2:
The physical parameter of baffle height is changed by adjusting the position of adjustment bolts and rotating nuts, enabling continuous variation in separation effectiveness to optimize stem removal while maintaining tobacco flow
2Productivity
If the baffling area of cut stems is reduced to improve separation rate, then the stem content in cigarettes decreases, but the structural design becomes more complex
Solution Approach 1:
The strut structure is divided into multiple segments (first strut segment, second strut segment, third strut segment) with different functions - the first segment provides support, the second segment creates the baffling area, and the third segment provides additional support, allowing optimized performance with modular design
Solution Approach 2:
Different portions of the strut structure have different properties - the hanging panel portion has reduced thickness to minimize baffling area for higher separation rate, while the support segments maintain sufficient thickness for structural strength, optimizing both separation performance and structural integrity
3Productivity
If the hanging panel thickness is reduced to decrease baffling area, then the stem separation rate improves, but the structural strength decreases
Solution Approach 1:
The hanging panel uses non-uniform thickness distribution - thinner in the central region where stem separation occurs to minimize baffling area, and thicker at the edges and attachment points to maintain structural strength and stiffness
Solution Approach 2:
The hanging panel incorporates curved or angled surfaces instead of flat surfaces, which distribute mechanical stresses more effectively and maintain strength while reducing the overall baffling area that interferes with stem separation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus significantly reduces the baffling area of cut stems, improves the separation rate of cut stems, and decreases the content of tobacco stems in cigarettes, thereby addressing quality issues such as excessive weight and piercing.
Implementation Method 1
a position correction spring, where the position correction spring is sleeved outside the inner hexagon adjustment bolt, and is located between a bottom surface of the connecting segment and the transverse hanging panel
Implementation Method 2
the connecting segment is provided with an adjustment screw in a vertical direction; and the support segment is configured to be fixed to a wall panel on both sides of the cut-stem separating baffle
