[0002] In related technologies, inkjet printers require an internal printing module for printing tasks. When changing to different thicknesses or easily deformable printing materials, the height of the printing module needs precise adjustment to avoid rubbing against the printhead and thus preventing damage. In these technologies, the height adjustment of the printing module is typically done manually, and after manual adjustment, it is mechanically locked.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 The printing device 1000 includes a support base 10, a push-pull assembly 20, a lifting assembly 30, and a printing assembly 40. The push-pull assembly 20 is mounted on the support base 10, the lifting assembly 30 is mounted on the push-pull assembly 20, and the printing assembly 40 is mounted on the lifting assembly 30. The support base 10, the push-pull assembly 20, the lifting assembly 30, and the printing assembly 40 are described in detail below.

[0022] To better explain the structure of the printing apparatus 1000, it will be described in conjunction with the first direction X, the second direction Y, and the third direction Z (vertical direction Z), wherein the first direction X is perpendicular to the second direction Y and the third direction Z.

[0023] For the aforementioned support base 10 and push-pull assembly 20, such as Figure 1 and Figure 2As shown, the push-pull assembly 20 is disposed on the support base 10, and the push-pull assembly 20 is movable relative to the support base 10 along a first direction X. The support base 10 includes a first support plate 101 and a second support plate 102 that are spaced apart from each other along the first direction X. Both the first support plate 101 and the second support plate 102 are used for mounting the push-pull assembly 20. Optionally, the first support plate 101 is provided with a plurality of first mounting holes 1011, which are spaced apart along the vertical direction Z. The second support plate 102 is provided with a plurality of second mounting holes 1021, which are spaced apart along the vertical direction Z. A second mounting hole 1021 and a first mounting hole 1011 are positioned opposite each other along the first direction X.

[0024] In some embodiments, the push-pull assembly 20 includes a first moving shaft 201, a second moving shaft 202, and a first limiting plate 203. One end of the first moving shaft 201 passes through the first support plate 101 and the second support plate 102 in sequence along the first direction X. One end of the second moving shaft 202 passes through the first support plate 101 and the second support plate 102 in sequence along the first direction X. The second moving shaft 202 and the first moving shaft 201 are arranged at intervals along the vertical direction Z. One end of the first limiting plate 203 along the vertical direction Z is connected to the other end of the first moving shaft 201. The other end of the first limiting plate 203 along the vertical direction Z is connected to the other end of the second moving shaft 202. The first limiting plate 203 is located on the side of the first support plate 101 away from the second support plate 102. Both the first moving shaft 201 and the second moving shaft 202 can move relative to the first support plate 101 and the second support plate 102 along the first direction X. Both the first moving shaft 201 and the second moving shaft 202 are connected to the lifting assembly 30. The user can push / pull the first moving shaft 201 and the second moving shaft 202 upward along the first direction X by holding the first limiting plate 203. Since the lifting assembly 30 is connected to the first moving shaft 201 and the second moving shaft 202, the first and second moving shafts can drive the lifting assembly 30 to move upward along the first direction X, thereby enabling the printing assembly 40 connected to the lifting assembly 30 to move upward along the first direction X. It is understood that to achieve the movement of the first moving shaft 201 and the second moving shaft 202 upward along the first direction X, it is not limited to the manual method described above; a mechanical mechanism can also be used, such as a hydraulic telescopic mechanism connected to the first limiting plate 203, to push / pull the first limiting plate 203 using the hydraulic telescopic mechanism.

[0025] In some embodiments, a connecting block 20a is provided on both the first moving shaft 201 and the second moving shaft 202, and the connecting block 20a is used to connect the lifting assembly 30.

[0026] In some embodiments, one end of the first movable shaft 201 is sequentially provided with a first mounting hole 1011 and a second mounting hole 1021 along the first direction X, and one end of the second movable shaft 202 is sequentially provided with another first mounting hole 1011 and another second mounting hole 1021 along the first direction X, thereby realizing the connection between the first movable shaft 201 and the second movable shaft 202 to the first support plate 101 and the second support plate 102.

[0027] In some embodiments, please refer to the following: Figure 2 The push-pull assembly 20 also includes multiple bearing assemblies 204. A single bearing assembly 204 is installed within a first mounting hole 1011 and / or a second mounting hole 1021. The single bearing assembly 204 is located at the connection between the first moving shaft 201 and the first support plate 101, and / or, a single bearing assembly 204 is located at the connection between the second moving shaft 202 and the second support plate 102. Optionally, the bearing assembly 204 includes a bearing housing 2041 and a linear bearing 2042. The linear bearing 2042 is installed within the bearing housing 2041, which is installed within the first mounting hole 1011 and / or the second mounting hole 1021. The linear bearing 2042 allows for smoother, more stable, and faster movement of the first moving shaft 201 and the second moving shaft 202 along the first direction X.

[0028] In some embodiments, the push-pull assembly 20 further includes a second limiting plate 205. One end of the second limiting plate 205 along the vertical direction Z is connected to one end of the first moving shaft 201, and the other end of the second limiting plate 205 along the vertical direction Z is connected to one end of the second moving shaft 202. The side of the second limiting plate 205 near the second support plate 102 away from the first support plate 101 is positioned such that when the first moving shaft 201 and the second moving shaft 202 move to a preset position along the first direction X, the second limiting plate 205 abuts against the second support plate 102. The second limiting plate 205 can be used to limit the movement distance of the first moving shaft 201 and the second moving shaft 202 along the first direction X, and at the same time, it can prevent the first moving shaft 201 and the second moving shaft 202 from detaching from the second support plate 102 during movement along the first direction X, thereby ensuring the normal movement of the first moving shaft 201 and the second moving shaft 202. In some embodiments, after the first moving axis 201 and the second moving axis 202 move a first distance from the second support plate 102 toward the first support plate 101, the second limiting plate 205 abuts against the second support plate 102. It is understood that the specific value of the first distance is not specifically limited in this application, and the user can set it according to actual needs.

[0029] In some embodiments, a handle 203a is provided on the side of the first limiting plate 203 away from the first support plate 101. The handle 203a makes it easier for the user to hold and push / pull the first limiting plate 203 more stably.

[0030] In some embodiments, please refer to the following: Figure 3 The printing device 1000 also includes a locking clamp 50, which is disposed on the side of the first support plate 101 opposite to the second support plate 102. The locking clamp 50 is movably connected to the first support plate 101 and is used to lock the first limiting plate 203 onto the first support plate 101. When the first moving shaft 201 and the second moving shaft 202 move a second distance along the first direction X, the first limiting plate 203 abuts against the first support plate 101. At this time, the locking clamp 50 can be used to lock the first limiting plate 203 onto the first support plate 101, thereby locking the push-pull assembly 20 to prevent displacement of the push-pull assembly 20 along the first direction X during the printing process. It is understood that the specific value of the second distance is not specifically limited in this application, and the user can set it according to actual needs.

[0031] In some embodiments, the first limiting plate 203 is provided with a locking hole 2031 on the side opposite to the second support plate 102. The locking hole 2031 is used to cooperate with the locking clamp 50 to lock the first limiting plate 203 onto the first support plate 101.

[0032] In some embodiments, the locking clamp 50 includes a handle 501, a connecting rod 502, and a clamp 503. One end of the connecting rod 502 is rotatably connected to the first support plate 101, and the other end of the connecting rod 502 is rotatably connected to the side of the handle 501 near the first support plate 101. One end of the handle 501 along the vertical Z direction is rotatably connected to one end of the clamp 503. The side of the clamp 503 near the first support plate 101 is rotatably connected to the first support plate 101, and the other end of the clamp 503 is provided with a locking block 5031. The handle 501 can rotate clockwise relative to the first support plate 101 to drive the clamp 503 to move toward the first limiting plate 203, and to allow the locking block 5031 to be inserted into the locking hole 2031, thereby locking the first limiting plate 203 to the first support plate 101. Optionally, the first support plate 101 is provided with a mounting plate 1012. The mounting plate 1012 can be used to install the connecting rod 502 and the clamp 503. The mounting plate 1012 is also provided with a limiting slot 1012a on the side opposite to the first support plate 101. The limiting slot 1012a is located between the connecting rod 502 and the clamp 503 in the vertical direction Z. After the locking block 5031 is inserted into the locking hole 2031, the clamp handle 501 can be rotated counterclockwise relative to the first support plate 101 until it is at least partially engaged in the limiting slot 1012a, thereby locking the clamp handle 501.

[0033] It should be noted that the plurality of first mounting holes 1011 on the first support plate 101 can also be arranged at intervals along the second direction Y, and the plurality of second mounting holes 1021 on the second support plate 102 can be arranged at intervals along the second direction Y, so that the first support plate 101 and the second support plate 102 can accommodate the installation of two sets of first moving shafts 201 and second moving shafts 202. It can be understood that the lifting assembly 30 and the printing assembly 40 can also be installed on the other set of first moving shafts 201 and second moving shafts 202.

[0034] For the aforementioned lifting assembly 30 and printing assembly 40, such as Figure 1 and Figure 4 As shown, the lifting component 30 is mounted on the push-pull component 20 and can move with the push-pull component 20. The lifting component 30 can move along the vertical direction Z. The printing component 40 is mounted on the lifting component 30 and can move along the vertical direction Z with the lifting component 30. When it is necessary to adjust the position of the printing component 40 in the vertical direction Z, the user can use the lifting component 30 to drive the printing component 40 to move along the vertical direction Z to a preset position for printing, thereby improving the adjustment efficiency of the printing component 40. Under the drive of the push-pull component 20, the printing component 40 can also move along the first direction X to a preset position for printing, thereby realizing the position adjustment of the printing component 40 in multiple directions, making the printing component 40 suitable for different application scenarios.

[0035] In some embodiments, please refer to the following: Figure 4 The lifting assembly 30 includes a mounting bracket 301, a driving component 302, a lead screw 303, and a connecting plate 304. The mounting bracket 301 is connected to the first moving shaft 201 and the second moving shaft 202. The driving component 302 is relatively fixed on the mounting bracket 301 and is driven by the lead screw 303. The lead screw 303 passes through the connecting plate 304 and can drive the connecting plate 304 to move vertically in the Z direction. The connecting plate 304 is connected to the printing assembly 40. Specifically, the driving component 302 drives the lead screw 303 to rotate, and the rotating lead screw 303 drives the connecting plate 304 to move vertically in the Z direction. The connecting plate 304 is connected to the printing assembly 40, thereby enabling the printing assembly 40 to move vertically in the Z direction. The lead screw 303 improves the accuracy of the printing assembly 40's vertical Z-direction movement distance. The lead screw 303 can rotate clockwise or counterclockwise to drive the connecting plate 304 to move vertically upward or downward in the Z direction. Whether clockwise rotation of the lead screw 303 corresponds to vertical movement of the connecting plate 304 in the Z direction, or counterclockwise rotation of the lead screw 303, is not specifically limited in this application; users can set it according to actual needs. Optionally, the driving component 302 is a servo motor.

[0036] In some embodiments, the lifting assembly 30 further includes a motor base 305, a reducer 306, a coupling 307, and a nut 308. The output end of the drive member 302 is connected to the reducer 306. Both the drive member 302 and the reducer 306 are mounted on the motor base 305. The motor base 305 is relatively fixed to the mounting bracket 301. The output end of the reducer 306 is connected to the lead screw 303 through the coupling 307. The nut 308 is relatively fixed to the connecting plate 304 and is threadedly connected to the lead screw 303. When the lead screw 303 rotates, the nut 308 moves in the vertical direction Z, thereby driving the connecting plate 304 to move in the vertical direction Z.

[0037] In some embodiments, the lifting assembly 30 further includes an anti-collision rubber 309, which covers the outer wall of the lead screw 303 and is located between the nut 308 and the motor base 305. The anti-collision rubber 309 can prevent the nut 308 from colliding with the motor base 305 during vertical Z-direction movement.

[0038] In some embodiments, the lifting assembly 30 further includes a guide rail 310 and a guide slider 311. The guide rail 310 is disposed on the side of the mounting bracket 301 opposite to the push-pull assembly 20. The guide slider 311 is slidably mounted on the guide rail 310. The guide rail 310 extends vertically in the Z-direction. The printing assembly 40 is connected to the end of the guide slider 311 opposite to the guide rail 310. The printing assembly 40 can slide along the guide rail 310 with the guide slider 311. The guide slider 311 and the guide rail 310 cooperate to make the printing assembly 40 move more stably in the vertical Z-direction.

[0039] In some embodiments, please refer to the following: Figure 5 The lifting assembly 30 also includes a first photoelectric sensor 312 and a second photoelectric sensor 313. Both the first and second photoelectric sensors 312 and 313 are disposed on one side of the mounting bracket 301 along the first direction X, and are spaced apart along the vertical direction Z. A baffle 401 is disposed on the side of the printing assembly 40 near the mounting bracket 301. During the movement of the printing assembly 40 along the vertical direction Z, the baffle 401 is positioned opposite to either the first or second photoelectric sensor 312. Both the first and second photoelectric sensors 312 and 313 are limit photoelectric sensors. The first photoelectric sensor 312 can be used to limit the maximum height that the printing assembly 40 can reach when moving upwards along the vertical direction Z, and the second photoelectric sensor 313 can be used to limit the minimum height that the printing assembly 40 can reach when moving downwards along the vertical direction Z.

[0040] In some embodiments, the mounting bracket 301 includes a first side plate 3011, a second side plate 3012, a third side plate 3013, and a fourth side plate 3014 connected in sequence. The first side plate 3011 and the third side plate 3013 are arranged opposite each other in the vertical direction Z, and the second side plate 3012 and the fourth side plate 3014 are arranged opposite each other in the first direction X. The first side plate 3011, the second side plate 3012, the third side plate 3013, and the fourth side plate 3014 enclose a limiting space 301a. A limiting block 402 is provided on the side of the printing assembly 40 near the mounting bracket 301. At least a portion of the limiting block 402 is located within the limiting space 301a. When the printing assembly 40 moves to a preset position in the vertical direction Z, the limiting block 402 abuts against the first side plate 3011 or the third side plate 3013. When the first photoelectric sensor 312 and the second photoelectric sensor 313 fail, the limiting block 402 can restrict the maximum and minimum height that the printing assembly 40 can move in the vertical direction Z. For example, when the printing assembly 40 moves upward in the vertical direction Z until the first side plate 3011 abuts against the limiting block 402, the printing assembly 40 moves to its maximum height in the vertical direction Z. When the printing assembly 40 moves downward in the vertical direction Z until the third side plate 3013 abuts against the limiting block 402, the printing assembly 40 moves to its minimum height in the vertical direction Z. It can be understood that limiting the displacement distance that the printing assembly 40 can reach in the vertical direction Z is mainly to prevent the printhead on the printing assembly 40 from being damaged by collision.

[0041] Furthermore, it is understood that in order to enable the printing assembly 40 to move vertically in the Z direction under the drive of the lifting assembly 30, the motion principle of the lifting assembly 30 is not limited to the above-mentioned cooperation between the motor and the lead screw 303, but can also be other motion principles, such as the motion principle of the hydraulic cylinder and the piston rod, the motion principle of the cylinder and the telescopic rod, etc.

[0042] In some embodiments, please refer to the following: Figure 1 The printing device 1000 also includes a vertical cable chain 60 and a horizontal cable chain 70. The vertical cable chain 60 is connected to the printing assembly 40 and the lifting assembly 30, and the horizontal cable chain 70 is connected to the printing assembly 40 and the push-pull assembly 20. When the printing assembly 40 moves up and down or moves in a push-pull motion, the vertical cable chain 60 or the horizontal cable chain 70 moves accordingly to avoid bending and pulling of the pipelines on the printing assembly 40.

[0043] It should be noted that: In this application, there are no specific restrictions on the structure of the printing component 40, as long as the printing component 40 can achieve the corresponding printing function.

[0044] In this embodiment, a support base 10, a push-pull assembly 20, a lifting assembly 30, and a printing assembly 40 are provided. The push-pull assembly 20 is disposed on the support base 10 and can move relative to the support base 10 along a first direction X. The lifting assembly 30 is disposed on the push-pull assembly 20 and can move with the push-pull assembly 20. The lifting assembly 30 can move along a vertical direction Z, which is perpendicular to the first direction X. The printing assembly 40 is disposed on the lifting assembly 30 and can move along the vertical direction Z with the lifting assembly 30. Compared to related technologies, where the height of the printing assembly 40 is adjusted manually, this method... In this embodiment of the application, when it is necessary to adjust the position of the printing component 40 in the vertical direction Z, the user can use the lifting component 30 to move the printing component 40 in the vertical direction Z to a preset position for printing, thereby improving the adjustment efficiency of the printing component 40. In addition, under the drive of the push-pull component 20, the printing component 40 can also move in the first direction X to a preset position for printing, thereby realizing the position adjustment of the printing component 40 in multiple directions, making it easy for the printing component 40 to be suitable for different application scenarios.

[0045] This application also provides an embodiment of a printing device, which includes the inkjet printing device 1000 as described above. The functions and structure of the inkjet printing device 1000 can be found in the above embodiments, and will not be repeated here.
