Description

Technical Field

[0001] The present invention relates to the field of photo printers, and particularly to a liftable printing carriage for a manual and automatic integrated photo printer. Background Art

[0002] The printing carriage of a printer, also known as a print head carriage or ink cartridge carriage, is an important component inside the printer. It is mainly responsible for moving left and right along the guide rail during the printing process, precisely spraying printing materials such as ink or toner onto paper or other media. The print head controls the opening and closing of the nozzles and the spraying amount according to the printing data. As the printing carriage moves and the print head sprays, the image or text on the paper gradually takes shape.

[0003] Printers usually have an adjustment mechanism for the distance between the printing carriage and the printing platform to meet the printing of items of different materials and sizes, and precisely control the inkjet quality and printing accuracy. Currently, some printers adjust the printing distance by adjusting the height of the printing platform, and some adjust the height of the printing carriage itself to adjust the printing distance. The height adjustment of the printing carriage itself is usually achieved through a regulating rod, a bevel gear set, and a lead screw. The utility model patent with the application number 2023232191384 discloses a printing carriage with this structure. The manual adjustment method of this printing carriage is relatively troublesome, and mainly relies on the vertically arranged lead screw and lead screw nut to support the lifting frame and achieve height adjustment. The load-bearing capacity of the thread is limited. During the printing operation, the self-weight of the lifting frame and the nozzle assembly installed inside it, as well as the vibration of the printer itself, often cause the phenomenon of slipping threads at the lead screw and lead screw nut, unable to stably support the lifting frame, and will affect the accuracy of the height adjustment of the printing carriage, which needs to be improved. Summary of the Invention

[0016] Example 1, see the attached Figures 1-7 , a manual and automatic integrated photo printer lifting printing trolley, the printing trolley includes a backplane 31 slidably connected to the trolley transverse movement track through a slider 311 and a lifting vertical plate 32 installed on the outer side of the backplane, and a nozzle 323 is connected to the lower part of the lifting vertical plate 32 through a bottom plate 321 and an end plate 322. The lifting vertical plate is slidably installed on the lower part of the outer side of the backplane 31. At both ends of the upper end surface of the lifting vertical plate, two top plates 324 are symmetrically arranged. The top plates 324 are vertically and fixedly connected to the lifting vertical plate 32. In the middle of the outer side of the backplane 31, an adjusting shaft 34 is horizontally installed through a fixed seat. At both ends of the adjusting shaft, cams 341 supported on the surface of the top plate 324 are installed. Rotating the adjusting shaft, the cam rotates and presses down on the surface of the top plate 324, driving the lifting vertical plate 32 to move downward. One end of the adjusting shaft 34 is installed with a handle 343. At both ends of the lifting vertical plate 32, two hanging plates 351 are symmetrically arranged. Corresponding hanging bolts 352 are arranged on the upper part of the backplane 31. A tension spring 353 is hung between the hanging bolt and the hanging plate 351. The tension spring 353 provides an upward pulling force for the lifting vertical plate 32. Combining with the pressing force of the cam 341, the lifting vertical plate 32 is in a fixed state.

[0017] At the end of the inner side of the lifting vertical plate 32, a lifting sliding seat 371 is provided. At the end of the backplane 31, a square hole 372 that is matched and sleeved on the lifting sliding seat is provided. A vertical shaft 373 that is fixedly connected in the square hole and slidably sleeved in the sliding hole of the lifting sliding seat 371 is provided. The lifting sliding seat is slidably connected in the square hole 372 through the vertical shaft 373. The square hole has a limiting effect on the lifting sliding seat 371, restricting the lifting sliding seat 371 from sliding within the length range of the square hole 372, playing a role in protecting the lifting vertical plate 32 and the nozzle 323 installed outside it, avoiding the phenomenon that the nozzle 323 hits the printing medium due to excessive downward movement, and ensuring the safety during the height socketing process.

[0018] As Figure 3As shown in the figure, an L-shaped limiting elastic piece 391 is installed in the middle of the end plate 322. A micro switch 392 is provided on the end plate 322 inside the L-shaped limiting elastic piece 391 and close to the L-shaped limiting elastic piece. Components such as a precision nozzle 323 are installed inside the carriage. If the carriage moves excessively due to improper control during printing, the L-shaped limiting elastic piece 391 will touch the relevant components of the printer in time, thereby triggering the micro switch. The micro switch 392 sends a signal to the drive motor 312 of the carriage, and the drive motor stops running in time.

[0019] As Figure 6 shown in the figure, a wear-resistant backing plate 325 is provided on the upper surface of the top plate 324. The cam 341 is supported on the wear-resistant backing plate. By providing the wear-resistant backing plate, the top plate is protected to avoid wear of the integral top plate 324. After the wear-resistant backing plate 325 is worn, it is convenient to replace.

[0020] When manually driving the adjustment shaft 34 to adjust the height of the printing carriage: ① Hold the handle 343 and rotate the adjustment shaft clockwise. The cam 341 rotates accordingly and presses down on the surface of the top plate 324. The lifting slide seat 371 at the end of the lifting vertical plate 32 slides down along the vertical shaft 373. At the same time, the hanging plate 351 pulls down the tension spring 353, and the lifting vertical plate 32 descends to adjust the height. ② Hold the handle 343 and rotate the adjustment shaft 34 counterclockwise. The cam 341 rotates upward and leaves the top plate 324. Under the pulling force of the spring, the lifting slide seat 371 at the end of the lifting vertical plate 32 slides up along the vertical shaft 373, and the lifting vertical plate 32 rises to adjust the height.

[0021] Example 2, see the attached Figures 1-7 to the specification. On the basis of Example 1, a driven gear 342 is installed in the middle of the adjustment shaft 34. A motor 312 is installed in the middle of the back plate 31 through the motor 312 seat. A driving gear 313 meshing with the driven gear 342 is installed on the back plate 31 at the end of the motor through a support. The output shaft 367 of the motor 312 is connected to the axle 366 of the driving gear 313. The size of the driving gear is smaller than that of the driven gear 342. Starting the motor 312 can drive the driving gear to rotate, and then drive the driven gear to rotate, driving the adjustment shaft 34 to rotate. The smaller driving gear 313 drives the larger driven gear 342 to drive the adjustment shaft 34 to rotate at a reduced speed.

[0022] A gear set is provided between the output shaft 367 of the motor 312 and the axle 366 of the driven gear 342. The gear set includes pinion gear A 361, pinion gear B 362, large gear A 363, and large gear B 364. The large gear A 363 is connected to the axle 366 of the driven gear 342, the pinion gear A 361 is connected to the output shaft 367 of the motor 312. An auxiliary seat is provided on one side of the support. A rotating shaft 365 is connected between the auxiliary seat and the support. Both the pinion gear B 362 and the large gear B 364 are mounted on the rotating shaft 365. The pinion gear B 362 and the large gear B 364 rotate synchronously with the rotating shaft 365. And the pinion gear B 362 meshes with the large gear A 363, and the large gear B 364 meshes with the pinion gear A 361. The motor 312 drives the pinion gear A 361 to rotate. The pinion gear A 361 drives the large gear B 364 and the pinion gear B 362 to rotate synchronously. The large gear B 364 drives the large gear A 363 to rotate. The large gear A 363 drives the driving gear 313 to rotate through the axle 366, and then drives the adjusting shaft 34 to rotate through the driven gear 342.

[0023] A limiting plate 381 is provided radially at the end of the adjusting shaft 34. A photo-coupler switch 382 is provided on the end plate 322. The limiting plate 381 corresponds to the position of the photo-coupler switch 382. After the adjusting shaft 34 drives the limiting plate 381 to rotate a certain angle, the limiting plate 381 triggers the photo-coupler switch 382. The photo-coupler switch 382 sends a limiting signal to the controller of the motor 312, and the motor 312 stops driving, avoiding the phenomenon that the spraying head 323 is damaged due to the excessive adjustment amplitude of the lifting vertical plate 32.

[0024] When adjusting the height of the printing carriage by driving the adjusting shaft 34 with the motor 312: ① Start the motor 312 to drive the pinion gear A 361 to rotate. The pinion gear A 361 drives the large gear B 364 to rotate to achieve the first-stage deceleration. At the same time, the large gear B 364 and the pinion gear B 362 rotate synchronously under the action of the rotating shaft 365. ② The rotation of the pinion gear B 362 drives the large gear A 363 to rotate for the second-stage deceleration. The large gear A 363 drives the driving gear 313 to rotate through the axle 366. The driving gear 313 drives the driven gear 342 to rotate to achieve the third-stage deceleration. ③ The driven gear 342 drives the adjusting shaft 34 to rotate between the two fixed seats, driving the cams 341 at both ends to rotate. ④ By controlling the forward and reverse rotation of the motor 312 to drive each gear to rotate forward or reverse, driving the adjusting shaft 34 and the cams 341 to rotate forward or reverse. The cams 341 press or release the top plate 324 at the end of the lifting vertical plate 32. Combining with the pulling force applied by the tension spring 353 to the lifting vertical plate 32, the automatic adjustment of the height of the printing carriage is realized.
