Wool Knitting Machine with Automatic Clamping and Accelerating Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operated wool knitting machines require manual holding of wool during the first knitting operation, resulting in an inconvenient and physically demanding process due to loose fabric formation and excessive physical strength consumption.
Innovation Solution
A novel wool knitting machine featuring a shell with a hollow annular groove housing a crochet needle cylinder, a yarn feeding device with a clamping mechanism, and a driving mechanism with an accelerating gear set, which includes a sensing module to automatically clamp the wool and reduce physical effort through increased knitting speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wool holding is used during first knitting operation, then fabric structure can be formed, but knitting process becomes inconvenient and physically demanding
Solution Approach 1:
The clamping device performs preliminary action by automatically clamping the wool before the knitting operation begins. The sensing module detects when the crochet needle reaches the yarn feeding port and triggers the clamping module to secure the wool in advance, eliminating the need for manual wool holding during the knitting process.
Solution Approach 2:
The knitting machine performs self-service through the automatic clamping mechanism. The sensing module and clamping module work together to automatically secure the wool without user intervention, allowing the machine to complete the knitting operation independently without requiring manual wool management.
2Productivity
If continuous handle rotation is used to complete knitting operation, then knitting can be performed, but physical strength consumption increases
Solution Approach 1:
The accelerating gear set acts as a mechanical amplifier that multiplies the effect of each hand crank rotation. This gear mechanism allows the user to apply smaller forces over longer periods, converting slow, sustained hand movements into faster needle movements without requiring peak physical strength.
Solution Approach 2:
The accelerating gear set changes the operational parameters by increasing the rotation speed of the crochet needle cylinder relative to the hand crank rotation. This parameter transformation allows the system to achieve higher knitting speeds while reducing the instantaneous force requirement from the user.

AI summary
A wool knitting machine comprising a shell, a knitting device, a yarn feeding device and a clamping device. When each crochet needle reaches the position of a yarn inlet of a yarn feeding port, the clamping device is clamped with the current crochet needle for clamping the wool, and at the same time, an accelerating gear device is arranged in a hand crank to increase the speed of hand knitting, so that a user can make the first knitting circle compact enough without manually tensioning the wool.
