[0018] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figures 1 to 3 As shown, this embodiment of an automatic rotating and lifting printing carriage assembly structure includes a printing carriage 3, a crossbeam 4 spanning above the paper, and a sliding base 5 slidably mounted on the crossbeam 4. The crossbeam 4 is vertically adjustable above the paper. A rotating shaft 31 is fixed to the upper center of the printing carriage 3. The rotating shaft is rotatably mounted on the sliding base 5. The sliding base 5 is equipped with a servo motor and a reducer. The servo motor is mounted on the reducer, and the rotating shaft 31 is mounted on the output shaft of the reducer. When the printing carriage 3 needs to switch modes, the servo motor drives the reducer to work. The torque is increased by the reducer, which further drives the printing carriage 3 to rotate, thus enabling the printing carriage 3 to switch modes. Compared with the manual rotation switching in the prior art, this achieves automated rotation switching. At the same time, compared with the side-flipping method in the prior art, the rotation of the printing carriage 3 is more stable and reliable. The centrifugal force during the rotation of the power shaft is smaller, and the life of the power shaft of the printing carriage 3 is longer.

[0020] As an improved specific embodiment, the printing trolley 3 is provided with a locking device 32 on the upper side, which locks and positions the printing trolley 3 after rotation.

After the printing trolley 3 is rotated in place, one of the locking electromagnets 321 magnetically attracts the magnetic lock block 322 to lock and position the printing trolley 3. On the one hand, the locking electromagnet 321 and the magnetic lock block 322 are locked by magnetic attraction, which has faster response speed than the traditional mechanical locking structure, and can quickly complete the locking action at the moment when the printing trolley is rotated in place, greatly improving the work efficiency.

Compared with the prior art without heating, the heated and constant-temperature controlled ink can reduce the viscosity, avoid the problems of poor ink flowability and mismatched printing waveform, and make the ink output by the nozzle array 34 more smooth.
