CIPP Liner Feed Roller With Adjustable Folding for Small Access Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for feeding UV cured CIPP liners into access openings lack configurability and are inefficient in folding the liners, making it difficult to maneuver them through smaller openings due to their bulkiness and weight.
Innovation Solution
A CIPP liner feed roller with a main roller, clamping roller, and adjustable distance between them, controlled by actuators and a drive unit, along with accessories like folding rollers and guide rollers to facilitate the feeding and folding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If UV cured CIPP liners are used, then environmental friendliness is improved, but maneuverability through smaller openings deteriorates due to increased thickness and weight
Solution Approach 1:
The CIPP liner is divided into multiple sections or segments that can be folded and connected. The folding mechanism allows the liner to be compacted into a smaller, more manageable form for insertion through access openings, then expanded to its full diameter once inside the conduit.
Solution Approach 2:
The CIPP liner is designed to fold nested upon itself multiple times, creating a compact bundled form that can pass through small access openings. The liner essentially nests within itself like a series of folded layers, reducing its effective width and height for insertion purposes.
2Ease of operation
If manual folding of CIPP liner is performed, then insertion through smaller openings is enabled, but productivity deteriorates due to increased labor time and complexity
Solution Approach 1:
The feed roller assembly incorporates adjustable rollers with variable spacing and positioning capabilities. The system can dynamically adapt the folding configuration based on the specific access opening dimensions and liner size, automating what was previously a manual process and improving feeding efficiency.
Solution Approach 2:
A specialized feed roller assembly acts as an intermediary device between the liner storage and the access opening. This mechanism automatically performs the folding and feeding operations, mediating the transition from bulk liner to inserted position without requiring manual intervention.
3Device complexity
If conventional feed methods are used, then simplicity of equipment is maintained, but adaptability to different liner sizes and opening configurations deteriorates
Solution Approach 1:
The feed roller assembly is designed as a universal system that can handle multiple liner sizes, types, and folding configurations through a single device. The adjustable rollers and modular components allow the same equipment to adapt to various conduit diameters and access opening dimensions without requiring specialized tools for each scenario.

AI summary
A CIPP liner feed roller for manipulating and feeding CIPP liner by pulling CIPP liner from a liner source and feeding it to where it is needed. The CIPP liner feed roller generally includes a main roller attached to a frame, a clamping roller attached to the frame and configured to be in parallel with the main roller, wherein the distance between the clamping roller and the main roller can be adjusted using one or more actuators, a drive unit comprising a motor configured to control the rotation of the main roller within the frame, a controller coupled to the drive unit and the one or more actuators, wherein the controller is configured to control the rotation of the main roller and the distance between the clamping roller and the main roller, and a support beam attached the frame and configured to be in parallel with the main roller.
