Rotary UV curing mechanism

Abstract

The invention relates to the field of ultraviolet irradiation crosslinking equipment, in particular to a rotary UV curing mechanism. The rotary UV curing mechanism comprises fixing side plates, a curing channel, a plurality of lamp caps, a driving motor and a length measuring device. Each fixing side plate comprises an outer fixing plate and an inner fixing plate; ultraviolet irradiation ends of the plurality of lamp caps face inwards, and the lamp caps are annularly and circumferentially distributed and fixed, and are rotationally installed in a group of inner fixing plates; the curing channel penetrates through the outer fixing plate and the inner fixing plate and penetrates into a lamp ring surrounded by the lamp caps; and the driving motor is fixed at the outer side of one outer fixingplate. According to the rotary UV curing mechanism, the mature annular surrounding-type lamp cap distribution is selected, and the rotary light irradiation is matched, so that the utilization rate ofthe light effect is improved, and the curing efficiency is improved; the whole structure is simple, the improvement cost is controllable, and a speed-reducing drive motor is adopted for driving rotation; the lamp caps are water-cooled, so that the heat exchange efficiency is higher; and the cable curing progress can be known in real time by matching with the length measuring device.

Description

technical field [0001] The invention relates to the field of ultraviolet radiation crosslinking equipment, in particular to a rotary UV curing mechanism. Background technique [0002] The conductor of the cable is usually wrapped with a layer of plastic protective layer. In the prior art, a layer of plastic protective layer is usually injected outside the conductor, and then the plastic protective layer is heated and cured. This curing method takes a long time and has low efficiency, so there are It is necessary to use rapid UV curing technology to cure the plastic protective layer. However, there is a problem of uneven illumination during UV curing, which affects the uniformity of curing. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, annular distribution, water-cooled lamp tube. UV ultraviolet light irradiation mechanism with high illumination efficiency. [0004] A rotary UV curing mechanism, including: a fixe...

[0002] The conductor of the cable is usually wrapped with a layer of plastic protective layer. In the prior art, a layer of plastic protective layer is usually injected outside the conductor, and then the plastic protective layer is heated and cured. This curing method takes a long time and has low efficiency, so there are It is necessary to use fast UV curing technology to cure the plastic protective layer. However, there is a problem of uneven illumination during UV curing, which affects the uniformity of curing.
