The motion process is briefly described as that the push block 17 moves to the right, so that the disc-shaped shell 34 rotates clockwise to enter the arc-shaped matching groove 24, the negative pressure cavity 20 is in a negative pressure state, the diaphragm 2 to be dried is adsorbed by the negative pressure to realize fixation, meanwhile, the pull rope 30 drives the first limiting rod 26 and the second gear 28 to move downwards through the negative pressure, the second gear 28 is separated from the rotation drive of the third gear 29, and the friction wheel 3 does not drive the diaphragm 2 to be dried to move to the right any more; the pressure sensitive switch 22 and the ultraviolet lamp tube 21 are communicated with an external power supply through the extrusion of the membrane 2 to be dried on the pressure sensitive switch 22, so that the strong ultraviolet radiation emitted by the ultraviolet lamp tube 21 generates chemical reaction on the ink on the membrane 2 to be dried, the surface is instantly cured, the water in the ink gradually enters the space of the negative pressure cavity 20 in the form of water molecules in the curing process, and the negative pressure state in the negative pressure cavity 20 is relieved; the adsorption fixation of the membrane 2 to be dried is released, the second gear 28 is meshed with the third gear 29 again, the friction wheel 3, the driven roller 7 and the cylindrical cam 8 continue to rotate, at the moment, the track of the outer contour sliding groove on the cylindrical cam 8 drives the connecting rod 11 and the toothed plate 13 to reset and move, the first gear 14 and the screw 15 both reset and rotate, the push block 17 is enabled to move leftwards integrally, and the disc-shaped shell 34 is enabled to be separated from the arc-shaped matching groove 24 through the left movement of the push block 17. In the negative pressure chamber 20
The working principle is as follows: when the printing ink UV drying equipment for processing the optical diaphragm is used, the diaphragm 2 to be dried can move rightwards intermittently by the matching of the drying main body 1 and the friction wheel 3, and during the period that the diaphragm 2 to be dried moves rightwards and is static, the drying operation is carried out on the printing ink on the diaphragm 2 to be dried by negative pressure generated in the drying main body 1 and UV drying, so that the drying efficiency on the diaphragm 2 to be dried is accelerated; the friction wheel 3 is supported by the fixed seat 4 during rotation, and the power supply device 5 is matched with the drying main body 1, so that when negative pressure is generated in the drying main body 1 and the membrane 2 to be dried is adsorbed, the power supply device 5 stops the rotation drive of the friction wheel 3; through the transmission of the transmission belt 6, when the friction wheel 3 rotates, the transmission belt 6 can drive the driven roller 7 to synchronously rotate; the cylindrical cam 8 can synchronously rotate along with the driven roller 7, and the cylindrical cam 8 during rotation is supported by the rear plate 12; when the cylindrical cam 8 rotates for a circle, the connecting rod 11 can slide back and forth on the side supporting plate 9 once under the matching of the through groove on the side supporting plate 9, and the toothed plate 13 on the connecting rod 11 moves synchronously; a first gear 14 meshed with the teeth on the toothed plate 13 carries a screw rod 15 to rotate on the side supporting plate 9 in a reciprocating mode; because the push block 17 can only perform limited sliding on the side plate 16, specifically, the left and right limited sliding, the motion state of the push block 17 is limited; and the left end of the push block 17 is provided with a threaded hole matched with the external thread on the screw rod 15, and after the screw rod 15 rotates in a reciprocating manner, the push block 17 can move in a reciprocating manner left and right on the side plate 16; through the matching of the push block 17 and the adsorption device 18, a negative pressure environment can be provided for the drying main body 1 so as to meet the actual UV drying requirement; through the matching use of the structures, the problem that in the actual use process, the drying effect and the quality at each position on the diaphragm are different due to the fact that the traditional printing ink drying equipment is low in efficiency and difficult to accurately control temperature change is solved; the existing UV drying equipment for the optical film also has the condition of low feeding and drying integration degree when in use, so that the drying efficiency is difficult to effectively improve, and the problem of inconvenience in use is solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
