[0030] Ultraviolet curing modules 5a and 5b are also installed above the middle part of the material rotating module base plate 37, which are used for curing the ink on the surface of the object to be printed.

[0031] When the object to be printed is installed, the cup clamp jig 7 is first removed, and the quick centering jig 75 is used to assist the operator to install a plurality of objects to be printed on the cup clamp jig 7, and the following will be described in detail according to the Figures 2-6 .

[0032] As shown in Figure 2 , three objects to be printed are installed on the cup clamp jig 7 in this embodiment, and the objects to be printed are handle-equipped mugs, the quick centering jig 75 is used below the cup clamp jig 7 to align the central axes of the three objects to be printed, and to stably string and fix the three objects to be printed on the cup clamp jig 7, so as to realize the effect of quick positioning and clamping.

[0033] As shown in Figures 3-5As shown, the cup clamping jig 7 includes a head end assembly 71, a tail end assembly 72, a middle sliding assembly, a cup bottom interface disc, a cup mouth interface disc, a sliding rod 74, and an air inflation end. The head end assembly 71 is arranged at one end of the cup clamping jig 7, and the tail end assembly 72 is arranged at the other end of the cup clamping jig 7. A sliding rod 74 is arranged on one side of the cup clamping jig 7 between the head end assembly 71 and the tail end assembly 72 along the generatrix direction of the object to be printed. The sliding rod 74 is a straight rigid structure, which plays a guiding and aligning role, can avoid deflection between the head end assembly 71, the tail end assembly 72, and the middle sliding assembly, and thus ensures that the central axes of the discs on the three assemblies coincide. A plurality of middle sliding assemblies 73 are arranged on the sliding rod 74. The middle sliding assembly is a precision sliding seat, which can be stopped at any position of the sliding rod 74 according to the length of the object to be printed. If three objects to be printed are arranged between the head end assembly 71 and the tail end assembly 72, two middle sliding assemblies 73a and 73b are arranged (as shown in Figure 3

[0034] A cup mouth interface disc is arranged inside the head end assembly 71 of the cup clamping jig 7, and a cup bottom interface disc is arranged inside the tail end assembly 72 of the cup clamping jig 7. A set of cup mouth interface discs and cup bottom interface discs are arranged on both sides of each middle sliding assembly. The cup mouth interface disc 731 cooperates with the cup mouth shape, and the cup mouth of the object to be printed abuts against the cup mouth interface disc. The cup bottom interface disc 732 cooperates with the cup bottom shape, and the bottom surface of the object to be printed abuts against the cup bottom interface disc. The cup mouth interface disc and the cup bottom interface disc cooperate with each other to clamp the object to be printed and fix it on the cup clamping jig 7. After the object to be printed is fixed and clamped, the cup clamping jig 7 automatically aligns the central axis of the object to be printed with the central axis of the cup clamping jig 7, and the center of each object to be printed coincides with the rotation center of the output shaft of the driving motor on the cup clamping jig 7. According to actual needs, a foamed silica gel sheet can be pasted on the cup mouth interface disc 731 and the cup bottom interface disc 732 to compensate for the slight manufacturing error of each object to be printed. At the same time, the foamed silica gel sheet can also increase the friction between the cup clamping jig 7 and the object to be printed, and enhance the printing stability.

[0035] The air inflation end of the cup clamping jig 7 is arranged on one side of the head end assembly 71, and the structure is as follows Figure 5 ​As shown, the inflation end includes a cylinder 711, a tower spring 714, an inflation port 712 and a deflation button 713. The head assembly 71 is provided with a cylinder 711 at one end, and a tower spring 714 is installed at the other end of the cylinder 711. The strength of the tower spring 714 is calculated by formula to ensure a stable clamping force when fixing the object to be printed, so as to clamp the object to be printed, and when the object to be printed rotates around the center axis at high speed, the object to be printed will not slip or be eccentric, avoiding the pattern from being blurred due to the deviation of ink drops during printing. At the same time, the spring clamping force is not too large to cause deformation of the workpiece. The cylinder 711 is matched with an inflation gun. The inflation gun is connected to the inflation port 712 on the jig to inflate the cylinder 711. At this time, the piston in the cylinder will retreat to drive the head assembly 71 to retreat and open the clamping mechanism. A deflation button 713 is provided beside the inflation port 712. The operator presses the deflation button 713, and the cylinder 711 is exhausted. At this time, the internal tower spring 714 pushes the piston rod to drive the head assembly 71 to move outward, clamps the cup jig 7, and thus completes the fixing work of the object to be printed.

[0036] The rapid centering jig 75 includes a first centering rod 751a, a second centering rod 751b and a positioning rod 752. The second centering rod 751b with a larger diameter and the first centering rod 751a are sequentially arranged on one side of the rapid centering jig 75. The first centering rod 751a and the second centering rod 751b are arranged along the first direction. The positioning rod 752 with a smaller diameter is arranged beside the first centering rod 751a and close to the slide rod 74. The positioning rod 752 is also arranged along the first direction. A side plate 753a is arranged at the end of the first centering rod 751a and the second centering rod 751b.

[0037] In actual work process, the operator first places the cup jig 7 on the rapid centering jig 75 on the two first centering rods 751a and the second centering rod 751b with a larger diameter, and then adjusts the cup jig 7 to make the positioning surface below the head assembly 71 abut against the positioning rod 752 with a smaller diameter of the rapid centering jig 75. Then the cup jig 7 is moved horizontally to the left to abut against the side plate 753a, and the rapid centering of the cup jig 7 is completed.

[0038] Next, the operator uses the air gun 754 to inflate the air inlet 712, opening the cup clamping fixture 7. The object to be printed is then placed on the first pair of mandrels 751a and the second pair of mandrels 751b, aligning the cup's central axis. When the object to be printed has a protruding part, such as a cup handle, the protruding part is pressed against the slide bar 74 to ensure that the placement angles of all objects with protruding parts are consistent. The object is then slid to the left, allowing the bottom surface of the first installed object to rest against the cup bottom interface plate 732a. The operator then pushes the middle sliding component 73a to press the top of the first object against the cup rim interface plate 731a, thus completing the positioning of the first object. Next, place the second object to be printed, with its bottom surface resting against the bottom interface plate 732b. Push the middle sliding component 73b by hand, so that the top of the object rests against the rim interface plate 731b, thus positioning the second object. Then, place the third object, with its bottom surface resting against the bottom interface plate 732c. Push the head component 71 by hand, so that the top of the object rests against the rim interface plate 731c, thus positioning the third object. After all three objects are in place, press the vent button 713. The rim interface plate 731c at the end will press firmly against the rim of the third object, securing all objects to the cup clamping fixture 7.

[0039] Next, the clamping fixture 7, with the object to be printed mounted, is installed onto the transfer module 3. For example... Figure 6 As shown, the tail end component 72 of the cup clamping fixture 7 has a sliding groove and a cylindrical hole design, which is used to quickly position and connect with the free top mandrel 34 of the transfer module 3 to form a center line coincidence; the head end component 71 of the cup clamping fixture 7 has a V-shaped groove and a conical hole design, which is used to quickly position and connect with the transfer shaft 33 of the transfer module 3 to form a center line coincidence.

[0040] Once the cup clamping fixture 7 is aligned with the position of the transfer module 3, the ejector cylinder 38 is extended to clamp the cup clamping fixture 7 between the transfer head module and the transfer tail module of the transfer shaft module 3. When it is necessary to remove the cup clamping fixture 7, the ejector cylinder 38 is retracted, allowing the cup clamping fixture 7 to be removed from between the transfer head module and the transfer tail module of the transfer shaft module 3. This loading and unloading method treats the cup clamping fixture 7 as a whole, allowing for modular operation, improving loading and unloading efficiency, facilitating operation, and optimizing structural design.
