Title:
CYCLOIDAL WEFT-INSERTION DRIVE MECHANISM FOR LOOM
Document Type and Number:
WIPO Patent Application WO/2015/161649
Kind Code:
A1
Abstract:
Disclosed is a cycloidal weft-insertion drive mechanism for a loom. A driving shaft (2) and a driven disc (6) are rotatably arranged on a machine frame (1), a first stage shift shaft (3) is fixedly provided on an end face of the driving shaft (2), a drive roller (4) is sheathed on the first stage shift shaft (3) via a first stage shift shaft bearing (8), the drive roller (4) extends into a sliding groove (5) on an end face of the driven disc (6) and is in a state of applying a force to a side wall of the sliding groove (5), and in the course of the driving shaft (2) rotating one cycle, the driven disc (6) will be driven to rotate 360° at a variable velocity ratio relative to the driving shaft (2) by means of the first stage shift shaft (3), the drive contact roller (4) and the sliding groove (5). The cycloidal weft-insertion drive mechanism for a loom has a simple and stable drive structure, fully meeting the distribution requirements of the time and angle of a rapier tape and rapier head in and out of the fell when the loom is weaving, has good rigidity, handover drive is flexible and the force of impact is low, effectively optimizing the trajectory of movement of the rapier tape and rapier head, and components are simple to machine, costs are low, inertia is low, and maintenance is easy, saving on production costs, improving loom operating efficiency, and parts performing reciprocating motion are few, which further assists in high speed operation.
