The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1 and Figure 2 The printing device includes a bracket 1, a lifting mechanism 2, and a printing platform 3. The lifting mechanism 2 is mounted on the bracket 1. The printing platform 3 includes a mounting frame 31 and multiple print heads 32. The multiple print heads 32 are fixed to the mounting frame 31. The mounting frame 31 is connected to the lifting mechanism 2. The lifting mechanism 2 is used to drive the mounting frame 31 to reciprocate along a first direction X, thereby driving the multiple print heads 32 to reciprocate synchronously along the first direction X.

[0021] For the lifting mechanism 2 mentioned above, please refer to Figures 2-6The lifting mechanism 2 includes a first drive assembly 21, two first lead screw guide rail assemblies 22, a second drive assembly 23, and two second lead screw guide rail assemblies 24. The mounting bracket 31 has two first lead screw guide rail assemblies 22 mounted on both sides of one end along the third direction Z, and two second lead screw guide rail assemblies 23 mounted on both sides of the other end along the third direction Z. The two first lead screw guide rail assemblies 22 and the two second lead screw guide rail assemblies 23 are respectively mounted on the mounting bracket 31, and the two first lead screw guide rail assemblies 22 are spaced apart along the second direction Y, as are the two second lead screw guide rail assemblies 23. The first drive component 21 is connected to the two first lead screw guide rail components 22. The first drive component 21 is used to drive the two first lead screw guide rail components 22 to move synchronously. The second drive component 23 is connected to the two second lead screw guide rail components 24. The second drive component 23 is used to drive the two second lead screw guide rail components 24 to move synchronously, so that the mounting frame 31 reciprocates along the first direction X, realizing the rising and falling of the mounting frame 31, wherein the first direction X is perpendicular to the second direction Y.

[0022] In some embodiments, the first drive assembly 21 includes a first drive motor 211, a first T-type commutator 212, two first connecting rods 213, and two first L-type commutators 214. The first drive motor 211 is connected to the first T-type commutator 212. The two ends of each first connecting rod 213 are respectively connected to the first T-type commutator 212 and the first L-type commutator 214. Each first L-type commutator 214 is connected to a first lead screw guide mechanism 22. The first T-type commutator 212 is used to transmit the power of the first drive motor 21 to the two first L-type commutators 214. A connecting rod 213 is connected to a first L-shaped commutator 214, which converts rotation about the second direction Y into rotation about the first direction X. The power of the first connecting rod 213 rotating about the second direction Y is transmitted to the two first lead screws 222 so that the two first lead screws 222 rotate synchronously about the first direction X. That is, after the first drive motor 211 drives the first connecting rod 213 to rotate, the power is transmitted to the two first lead screws 222 through the first L-shaped commutator 214, so that the two first lead screws 222 can rotate at the same time. This realizes that one first drive motor 211 drives the two first lead screws 213 to rotate, which is beneficial to saving costs.

[0023] It is worth noting that the structure of the first drive assembly 21, which realizes a motor driving two lead screws, is not limited to the structure described above. Other structures are also possible. For example, the first drive assembly 21 includes a transmission belt (not shown), a motor (not shown), and a transmission wheel (not shown). The motor is fixed to the bracket, and the output shaft of the motor is connected to the transmission wheel. The transmission belt is wound around the two first lead screws 222 and the transmission wheel. The motor drives the transmission wheel to rotate, and the transmission wheel drives the transmission belt. The transmission belt synchronously drives the two first lead screws 222 to rotate.

[0024] The first lead screw guide rail assembly 22 includes a first fixed platform 221, a first lead screw 222, a first guide rail 223, and a first slider 224. The first fixed platform 221 and the first guide rail 223 are both fixed to the bracket 1. The first guide rail 223 extends along the first direction X. The first lead screw 222 is rotatably mounted on the first fixed platform 221. The first lead screw 222 of the first lead screw guide rail assembly 22 is connected to a first L-shaped commutator 214. The first slider 224 is sleeved and screwed onto the first lead screw 222. The first slider 224 is slidably mounted on the first guide rail 223. The first slider 224 is connected to the mounting bracket 31. The first lead screw rotates under the drive of the first drive motor 211. The rotation of the first lead screw 222 drives the first slider 224 to reciprocate along the first direction X. The first slider 224 drives the printing platform 3 to reciprocate along the first direction X.

[0025] In some embodiments, the first lead screw guide rail assembly 22 further includes two first limiting blocks 225, which are fixed to the bracket 1, and one of the first limiting blocks 225 is located at the end of the first guide rail 223 away from the first L-shaped commutator 214, and the first limiting block 225 is used to limit the stroke of the first slider 224.

[0026] The second drive assembly 23 includes a second drive motor 231, a second T-type commutator 232, two second connecting rods 233, and two second L-type commutators 234. The second drive motor 231 is connected to the second T-type commutator 232. The two ends of one of the second connecting rods 233 are respectively connected to the second T-type commutator 232 and one of the second L-type commutators 234. One of the second L-type commutators 234 is connected to a second lead screw guide assembly 24. The second T-type commutator 232 is used to transmit the power of the second drive motor 231 to the two second L-type commutators 234. The connecting rod 233 and the second L-shaped commutator 234 convert the rotation about the second direction Y into rotation about the first direction X, and transmit the power of the second connecting rod 233 rotating about the second direction Y to the second lead screw 242, so that the second lead screw 242 rotates about the first direction X. That is, after the second drive motor 231 drives the second connecting rod 233 to rotate, the power is transmitted to the two second lead screws 242 through the second L-shaped commutator 234, so that the two second lead screws 242 can rotate at the same time, realizing that one second drive motor 231 drives two second lead screws 242 to rotate, which is beneficial to saving costs.

[0027] The second lead screw guide rail assembly 24 includes a second fixed platform 241, a second lead screw 242, a second guide rail 243, and a second slider 244. The second fixed platform 241 and the second guide rail 243 are both fixed to the bracket 1. The second guide rail 243 extends along the second direction Y. The second lead screw 242 is rotatably mounted on the second fixed platform 241. The second lead screw 242 of the second lead screw guide rail assembly 24 is connected to a second L-shaped commutator 234. The second slider 244 is sleeved on and screwed to the second lead screw 242. The second slider 244 is slidably mounted on the second guide rail 243. The second slider 244 is connected to the mounting bracket 31. The second lead screw 242 rotates under the drive of the second drive motor 231. The rotation of the second lead screw 242 drives the second slider 244 to reciprocate along the first direction X. The second slider 244 drives the printing platform 3 to reciprocate along the first direction X.

[0028] In some embodiments, the second lead screw guide rail assembly 24 further includes two second limiting blocks 245, which are fixed to the bracket 2, and one of the second limiting blocks 245 is located at the end of the second guide rail 243 away from the second L-shaped commutator 234, and the second limiting block 245 is used to limit the stroke of the second slider 244.

[0029] It is worth noting that the lifting mechanism 2 is not limited to the structure described above. For example, the lifting mechanism 2 may only include a first drive assembly 21 and a first lead screw guide assembly 22, wherein there is only one first lead screw guide assembly 22, and the first drive assembly 21 drives the mounting frame 31 to rise and fall through the first lead screw guide assembly 22; or, the lifting mechanism 2 may include a first drive assembly 21 and two first lead screw guide assemblies 22, but may not include a second drive assembly 23 and two second lead screw guide assemblies 24, wherein the two first lead screw guide assemblies 22 are located in the middle of the mounting frame 31, and the first drive assembly 21 drives the mounting frame 31 to rise and fall by driving the two first lead screw guide assemblies 22.

[0030] In addition, the first L-type commutator 214, the second L-type commutator 234, the first T-type commutator 212 and the second T-type commutator 232 are all existing technologies.

[0031] In some embodiments, please refer to Figure 1 The printing equipment also includes a maintenance and moisturizing device 4, which comprises a maintenance and moisturizing component 41, a slide rail 42, and a pushing component (not shown). The slide rail 42 is mounted on the bracket 1 and extends along a third direction Z. The maintenance and moisturizing component 41 is slidably disposed on the slide rail 42. The pushing component is connected to the maintenance and moisturizing component 41 and is used to push the maintenance and moisturizing component 41 to slide back and forth along a third direction Z. For example, when the printhead 32 needs maintenance, the pushing component first pushes the maintenance and moisturizing component 41 below the printhead 32, and then the printhead 32 descends into the maintenance and moisturizing component 41 for maintenance. After maintenance is completed, the printhead 32 rises, and the pushing component pushes the maintenance and moisturizing component 41 away from the movement path of the printhead 32 to avoid affecting the raising and lowering of the printhead.

[0032] The actuation component can be a cylinder, a linear motor, or the like.

[0033] In this embodiment of the invention, the printing device includes a bracket 1, a lifting mechanism 2, and a printing platform 3. The lifting mechanism 2 is mounted on the bracket 1. The printing platform 3 includes a mounting frame 31 and multiple printheads 32. The multiple printheads 32 are fixed to the mounting frame 31. The mounting frame 31 is connected to the lifting mechanism 2. The lifting mechanism 2 is used to drive the mounting frame 31 to reciprocate along a first direction X, thereby driving the multiple printheads 32 to reciprocate synchronously along the first direction X. That is, driving one lifting mechanism 2 can simultaneously lift and lower the printing platform 3 on which multiple printheads 32 are mounted, saving costs.
