Belt Drive Unit With Switchable Teeth for Variable Fin Bore Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt drive units for molding machines with bored fins are not adaptable to bores of varying diameters, requiring complex manual adjustments and specialized operator intervention for changes from smaller to larger or larger to smaller diameters.
Innovation Solution
The drive unit is equipped with interchangeable support plates featuring vertical teeth of varying diameters, controlled by a remote system allowing easy switching between smaller and larger diameter configurations without manual assembly or disassembly, using springs and fluid control for lifting and lowering the plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the drive unit uses fixed teeth for moving forward and positioning the belt, then the machine can effectively mold fins with constant bore diameter, but the machine cannot adapt to fins with varying bore diameters without complex manual adjustments
Solution Approach 1:
The patent implements a dynamic configuration system where the support plates can be selectively positioned in different radial positions (first, second, third positions) to accommodate varying bore diameters. The control unit automatically selects and positions the appropriate support plate based on the required bore diameter, transforming the static drive unit into a dynamically adaptable system without manual intervention.
Solution Approach 2:
The drive unit is designed with multiple support plates (first, second, third support plates) that can serve different functions for different bore diameters. Each support plate is configured with teeth suitable for specific diameter ranges, allowing a single drive unit to universally handle multiple fin types with varying bore diameters through automated plate selection rather than requiring separate drive units for each diameter.
2Adaptability or versatility
If specialized operators manually replace plates with teeth to change bore diameter capacity, then the drive unit can be reconfigured for different diameters, but the process is time-consuming and requires specialized skills
Solution Approach 1:
The system implements self-service automation where the control unit automatically selects, positions, and configures the appropriate support plate based on the required bore diameter. The motorized actuation system and sensors enable the drive unit to reconfigure itself without human intervention, eliminating the need for specialized operators and significantly reducing reconfiguration time from manual plate replacement to automated selection and positioning.
Solution Approach 2:
Multiple support plates with different tooth configurations are pre-configured and positioned in ready-to-use locations (different radial positions). When a change in bore diameter is required, the control unit simply activates the pre-positioned appropriate plate rather than requiring assembly or modification, enabling rapid switching between different fin types through pre-prepared configurations.
3Adaptability or versatility
If the drive unit is designed for larger diameter teeth, then it can handle larger bore diameters, but it cannot effectively mold fins with smaller diameter bores
Solution Approach 1:
The drive unit employs a dynamic support plate selection mechanism that automatically adjusts which plate is active based on the required bore diameter. For larger diameters, larger-toothed plates are positioned in the active radial position; for smaller diameters, smaller-toothed plates are automatically selected and positioned. This dynamic adaptation maintains ease of operation through automated selection rather than requiring manual adjustment of tooth size for each operation type.
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
Facilitates seamless transitions between molding fins with different bore diameters using a simple command, eliminating the need for specialized operators and reducing operational complexity, enabling efficient operation without manual reconfiguration of the drive unit.
Implementation Method 1
a spring arranged underneath the intermediate plate and acting on the lower surface thereof, pushing the intermediate plate in a downward direction
Implementation Method 2
reactive force of the spring to push the support plate with the teeth of smaller diameter in an upward direction to the operating plane
Implementation Method 3
a control unit arranged to actuate the actuator to switch the drive unit from the first configuration to the second configuration and vice versa

AI summary
A drive unit (4) of the belt (3) for a molding machine (1) of bored fins comprises a fixed front part (12) and a movable rear part (13) driven longitudinally with a forward and backward movement to and from the fixed front part (12). Both parts (12, 13) of the drive unit (4) include support plates (16, 31) on the upper surfaces thereof for vertical teeth (20, 35) with oblique top (22, 37) which protrude upwards under elastic thrust (24, 39) and are suitable for being inserted into corresponding bored collars (52) of the belt (3) downstream of a boring unit (2) of the molding machine (1). The upper surfaces of each of the two parts (12, 13) of the drive unit (4) support at least a further support plate (17, 32) for vertical teeth (21, 36) of greater diameter, which is liftable and lowerable by a control panel (50).
