DYNAMICALLY ASSISTED TEXTILE DYE PRESSING ROLLER PREVENTING UNEVEN PRESSURE FROM CENTRE TO EDGES

摘要

Disclosed is a dynamically assisted textile dye pressing roller preventing uneven pressure from the centre to the edges. The roller comprises a hollow outer roller (4), wherein two ends of the outer roller (4) are mounted on a machine frame via a first bearing set (3), an inner roller (6) is provided through an inner cavity of the outer roller (4), and an axle (8) of the inner roller (6) is connected to a power apparatus (1). By means of the inner roller (6) passing through the pressing roller, the weight of the whole unit is increased; an electrical motor drives the inner roller (6) to rotate at a high speed, the inner roller (6) then drives the outer roller (4) to rotate at a low speed complying with the need, meeting production demands. In addition, the centre of gravity of the heavy inner roller (6) rotating at a high speed tends towards the axis of rotation, that is to say if the outer roller (4) generates deformation, the inner roller (6) will also be driven to generate deformation, the centre of gravity of the inner roller (6) is offset from the axis of rotation and at this point, a stress will be generated, making the centre of gravity of the inner roller (6) return to the axis of rotation and driving the outer roller (4) to overcome the deformation, making the pressure of the inner roller (6) even, and thereby solving problems caused by differences in pressure and the problem of colour differences from the centre to the edges.
