Kneading Degree Adjusting Apparatus with Bent Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kneading degree adjusting apparatuses have a limited range for adjusting the kneading degree due to the risk of metallic contact between the gate member and the cylindrical segment, which restricts the widening of the kneading degree range and can lead to reduced kneading quality.
Innovation Solution
A kneading degree adjusting apparatus with a gate member that moves toward and away from a cylindrical segment, forming a bent passage by using a convex part on one of the outer circumference and a concave part on the other, increasing passage resistance and allowing for a wider adjusting range without risking metallic contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gate member is moved closer to the cylindrical segment to widen the adjusting range for kneading degree, then the upper limit of the adjusting range is raised, but metallic contact between the gate member and the cylindrical segment occurs causing abnormal wear and seizure
Solution Approach 1:
A convex part is formed on the gate member and a concave part is formed on the cylindrical segment (or vice versa). This intermediary geometric feature creates a bent passage that increases material flow resistance without requiring the gate member to contact the cylindrical segment, thus preventing metallic contact while achieving the desired kneading effect
Solution Approach 2:
The invention changes the geometric parameters of the passage by introducing convex and concave parts. This modifies the flow path shape from straight to bent, increasing the effective path length and resistance without changing the overall distance between the gate member and cylindrical segment, thereby preventing contact while maintaining kneading control
2Reliability
If the gate member is moved away from the cylindrical segment to prevent metallic contact, then the adjusting range for kneading degree is limited, but the risk of abnormal wear and seizure is reduced
Solution Approach 1:
The convex and concave parts act as intermediaries that increase passage resistance without requiring close proximity between the gate member and cylindrical segment. This allows the components to be positioned farther apart (preventing contact) while still achieving sufficient kneading through the bent passage geometry
Solution Approach 2:
Instead of increasing resistance by reducing the radial gap (one dimension), the invention introduces a bent path in the axial dimension through convex and concave parts. This dimensional change allows the gate member to be positioned farther from the cylindrical segment while maintaining effective kneading control

AI summary
Provided is a kneading degree adjusting apparatus, which can have a wide adjusting range for a kneading degree even if a gate member and a cylindrical segment are not made so close as to invite a fear of metallic contacts. The kneading degree adjusting apparatus is disposed in a kneading treatment equipment, which includes a cylindrical segment formed at a predetermined portion and a kneading screw for kneading a material while feeding the same to the downstream side, thereby to adjust the kneading degree of the material. The kneading degree adjusting apparatus comprises a gate member having an opposed face confronting the outer circumference of the cylindrical segment and moved toward and away from the outer circumference of the cylindrical segment thereby to change the area of the material passage to be formed between the opposed face and the outer circumference of the cylindrical segment. The outer circumference and the opposed face are corrugated to form the passage into a bent shape.
