The design principle of the printing and pre-curing process of the object to be printed 0 will be described in detail with reference to fig. 7, wherein the object to be printed 0 cannot rotate 360 degrees due to the protruding portion of the object to be printed 0, such as the cup handle portion, or otherwise collides with the spray head. The protruding part of the object to be printed 0 is a avoiding nozzle and can reciprocate in the printing process, when one side of the protruding part is close to the nozzle, the protruding part reversely rotates, when the protruding part reversely rotates to the position where the protruding part is close to the nozzle, the direction of the protruding part is changed, the protruding part reversely rotates to the position where the protruding part is close to the nozzle, and the protruding part reversely rotates again, so that the printing process is repeated. According to the above reciprocating rotation method, if a curing device LA is provided, since the object 0 to be printed cannot rotate 360 degrees, a blind area which cannot be irradiated by the unique curing device will occur when the graphics on the object is cured, so that a second curing device LB needs to be provided at a symmetrical position to compensate an area which cannot be irradiated by the curing device, according to the simulation calculation of the blind area, the angle difference LP between the curing device and the horizontal direction needs to be less than or equal to (180-DA)/2, where LP is an included angle between the outer edge of the horizontal line L passing through the center of the object to be printed and the horizontal line L, where DA represents a blind area included angle where the protruding part of the object is a nozzle, and cannot rotate. In addition, since the protruding portion has a certain height HD, the first curing device LA and the second curing device LB should be located at positions where the radial distance from the surface of the object to be printed 0 is required to be greater than HD, and the capability of curing the ink is weak, which is defined as a preliminary pre-curing process.
When the image and text is printed on the object to be printed 0, the pre-curing process which is synchronously carried out with the object to be printed 0 is also completed, and then the final curing process is carried out. As shown in fig. 8, the image and text on the surface of the object 0 to be printed is printed, the print carriage is retracted to the initial printing position along the first direction (X-axis direction), so as to avoid collision by the protruding portion of the object 0 to be printed, and at the same time, a curing device moves close to the object 0 to be printed along the radial direction of the object, in this embodiment, a second curing device LB moves close to the object 0 to be printed along the radial direction of the object, and the control system controls the object 0 to be printed to reciprocate in a manner of avoiding the second curing device LB, so that in the reciprocation process, the capability of curing ink is strong, and the curing device LB performs final curing treatment on ink drops on the surface of the object.
Next, a brief description will be given of the acquisition of positional information of the height HD of the projecting portion of the object to be printed, which is the blind area angle DA where the projecting portion of the object to be printed is not rotatable for avoiding the head. Fig. 9 is a schematic diagram of detecting the height of the protruding portion of the object to be printed, in this embodiment, the object to be printed is a mug, a set of correlation sensors are disposed at two ends of the beam mechanism 1, and the height of the protruding portion of the object to be printed is detected by the correlation sensors, so that the height of the cup clamping jig 7 for fixing the object to be printed in the vertical direction is controlled, and the distance between the two curing devices and the object to be printed in the printing process is determined.
Fig. 10-12 are schematic diagrams of detecting a protruding portion of an object by a sensor according to another embodiment of the present invention, in fig. 10, the protruding portion of the object to be printed is located right below, a left sensor LS is installed on the left side, a right sensor RS is installed on the right side, the control system controls the object to be printed to rotate clockwise, when the outer edge of the protruding portion is close to the nozzle, as shown in fig. 11, the left sensor LS detects an encoder position signal P1 corresponding to the protruding portion at this time, then the control system controls the object to be printed to rotate counterclockwise again, when the outer edge of the other side of the protruding portion is close to the other side of the nozzle, as shown in fig. 12, the right sensor RS detects an encoder position signal P2 corresponding to the protruding portion at this time, and at this time, software can calculate the length of a print area rotated by avoiding the nozzle, the length is (P2-P1)/(number of lines×2r of one turn of the encoder, and R represents the radius of the object to be printed. According to the position signals P1 and P2 fed back after the sensor is triggered, the reciprocating motion track of the object to be printed can be controlled, and the printing effect that the protruding part automatically avoids the spray head is achieved.
