[0042] Figure 5This is a perspective view of the printing carriage and its base in one embodiment of the inkjet printer of this utility model. In some embodiments, the printing carriage 210 further includes a support frame 212 and an ink cartridge 213. The support frame 212 is connected to the front and rear drive components 220, the inkjet head 211 is mounted on the support frame 212, and the ink cartridge 213 is detachably mounted on the support frame 212.

[0043] like Figure 3 , 4 In this embodiment, the reciprocating transmission component 223 is a lead screw assembly, which includes a lead screw 2231 and a movable block 2232 that cooperates with the lead screw 2231. The lead screw 2231 is mounted on the carriage base 221 and extends in a direction perpendicular to the printing surface 110. The lead screw 2231 is connected to the drive component 222, and the movable block 2232 is connected to the carriage 210. The drive component 222 drives the lead screw 2231 to rotate, causing the movable block 2232 to move along the extension direction of the lead screw 2231.

[0044] like Figure 3 , 4 In this embodiment, the driving component 222 is a stepper motor 222a. The stepper motor 222a rotates when energized, thereby driving the lead screw 2231 to rotate.

[0045] Figure 6 This is a perspective view of the front and rear drive components in an alternative embodiment of the inkjet printer of this utility model. In the alternative embodiment, the drive component 222 is a rotary handle 222b, which can rotate under hand-tightening action, thereby driving the lead screw 2231 to rotate.

[0046] In some embodiments, the coding device further includes a controller electrically connected to the coding carriage assembly 200. The controller is configured to, upon receiving print job information, control the front and rear drive assemblies 220 to move the carriage 210 so that the inkjet head 211 is 2 mm to 5 mm away from the surface of the object to be coded.

[0047] According to the coding device of this embodiment, the front and rear drive components 220 can drive the carriage 210 to move in a direction perpendicular to the printing surface 110. After receiving the printing task information, the controller controls the front and rear drive components 220 to drive the carriage 210 to move so that the inkjet head 211 is 2 mm to 5 mm away from the surface to be coded, so that there is a better coding distance between the inkjet head 211 and the surface to be coded, thereby ensuring stable coding quality.

[0048] like Figure 1In some embodiments, the inkjet shell 100 has a shell opening 120, and an edge of the shell opening 120 is provided with an uncovering inductor 130. In some embodiments, the inkjet device further comprises a cover 300 and a displacement driving assembly 400. The cover 300 comprises a trigger 310. The cover 300 has a covering state and an uncovering state.

[0049] In the covering state, the cover 300 covers the shell opening 120. In the uncovering state, the cover 300 exposes the shell opening 120, and the trigger 310 causes the uncovering inductor 130 to generate an uncovering induction signal. The displacement driving assembly 400 is arranged in the inkjet shell 100, and the displacement driving assembly 400 can drive the inkjet carriage assembly 200 to move in a first direction X, which is a transverse direction parallel to the printing surface 110.

[0050] The controller is electrically connected with the uncovering inductor 130 and the displacement driving assembly 400. In some embodiments, the controller is configured to, after receiving the uncovering induction signal, control the inkjet carriage assembly 200 to stop inkjetting and control the displacement driving assembly 400 to drive the inkjet carriage assembly 200 to move to a first preset position to stop the printing operation.

[0051] Specifically, in some embodiments, the controller is configured to, after receiving the printing task information, control the displacement driving assembly 400 to drive the inkjet carriage assembly 200 to move and control the inkjet carriage assembly 200 to inkjet to perform the printing operation; and after receiving the uncovering induction signal, control the inkjet carriage assembly 200 to stop inkjetting and control the displacement driving assembly 400 to drive the inkjet carriage assembly 200 to move to the first preset position to stop the printing operation. Therefore, after the printing operation has started, if the cover 300 is opened, the uncovering inductor 130 generates the uncovering induction signal, and the controller controls the displacement driving assembly 400 and the inkjet carriage assembly 200 to stop the printing operation, and the inkjet carriage assembly 200 no longer continues to perform the printing operation but moves back and forth, thereby providing uncovering protection when the cover 300 is opened, so as to eliminate the safety hazard after the cover 300 is opened.

[0052] In some embodiments, the controller is configured to, after receiving the uncovering induction signal, control the inkjet carriage assembly 200 to stop inkjetting and control the displacement driving assembly 400 to drive the inkjet carriage assembly 200 to move to an original printing position first and then to an uncovering position, wherein the uncovering position of the inkjet carriage assembly 200 corresponds to the shell opening 120, so that the shell opening 120 exposes the inkjet carriage assembly 200. After receiving the uncovering induction signal, the displacement driving assembly 400 drives the inkjet carriage assembly 200 to move to the original printing position first, and then drives the inkjet carriage assembly 200 to move to the uncovering position based on the original printing position, thereby ensuring the position accuracy of the inkjet carriage assembly 200 to reach the uncovering position.

[0053] In some embodiments, the controller is further configured to, after receiving the cover opening sensing signal, control the front and rear driving assembly 220 to drive the trolley 210 to move to a second preset position, so that the inkjet head 211 is recessed in the code printing opening 111. Therefore, after the cover is opened, the code printing device stops the printing operation, and the code printing trolley assembly 200 moves to the shell opening 120 along the first direction X, and the front and rear driving assembly 220 drives the trolley 210 to move to the second preset position, at this time, the trolley 210 is closer to the shell opening 120 in the direction perpendicular to the printing surface 110, thereby further facilitating the maintenance of the trolley 210.

[0054] In some embodiments, the code printing device further comprises a storage rack 500.

[0055] Figure 7 FIG. 1 is a perspective view of a storage rack of an embodiment of the code printing device of the present application. The storage rack 500 comprises a tray 510 for carrying objects to be coded, and the tray 510 is installed on the side of the printing surface 110 of the code printing shell 100.

[0056] In some embodiments, the storage rack 500 further comprises a first grid guide rail 520 and a support assembly 530. The support assembly 530 comprises a support member 531 and a first elastic lock 532. The tray 510 is installed on the support member 531.

[0057] Figure 8 FIG. 2 is a cross-sectional view of the storage rack of an embodiment of the code printing device of the present application when the first elastic lock is unlocked. The first grid guide rail 520 comprises a first grid structure arranged in the longitudinal direction. The first grid structure comprises a plurality of first protrusions 521 arranged in the longitudinal direction Z and a first groove 522 located between adjacent first protrusions 521. At least part of the lower surface of each first protrusion 521 is a first inclined surface S1 arranged obliquely to the horizontal plane. The first elastic lock 532 is connected to the support member 531. The support member 531 is movable along the first grid structure. The first elastic lock 532 comprises a first clamping jaw U1 capable of extending into the first groove 522. The first elastic lock 532 is arranged to extend the first clamping jaw U1 into the first groove 522 under the action of its own elastic force, and the first clamping jaw U1 can switch to extend into the adjacent upper first groove 522 through the first inclined surface S1 when the support member 531 is subjected to an upward external force.

[0058] Figure 9 FIG. 3 is a cross-sectional view of the storage rack of an embodiment of the code printing device of the present application after the first elastic lock is unlocked. In some embodiments, by exerting a specific force on the first elastic lock 532, the first elastic lock 532 can be moved against its own elastic force, so that the first clamping jaw U1 is away from the first groove 522, thereby achieving unlocking of the first elastic lock 532. After unlocking, the tray 510 can be adjusted downward along the first grid structure.

[0059] In the above embodiment, the shelf 500 comprises the first grid rail 520, the support assembly 530, and the tray 510. The first grid rail 520 comprises a first grid structure arranged along the longitudinal direction Z, which comprises a plurality of first protrusions 521 arranged along the longitudinal direction Z and a first groove 522 located between adjacent first protrusions 521, wherein at least part of the lower surface of each first protrusion 521 is a first inclined surface S1 arranged obliquely to the horizontal plane. The support assembly 530 comprises a support piece 531 and a first elastic lock 532, and the first elastic lock 532 comprises a first clamping jaw U1 capable of extending into the first groove 522. The first elastic lock 532 is arranged to extend the first clamping jaw U1 into the first groove 522 under the action of its own elastic force, so that the first clamping jaw U1 of the first elastic lock 532 can be clamped in the first groove 522 in the state that the shelf 500 is only subjected to gravity, thereby achieving locking of the tray 510 in the longitudinal direction Z, avoiding accidental falling of the tray 510, and improving the stability of the longitudinal Z position of the tray 510. When it is necessary to adjust the position of the tray 510 upward, the tray 510 or the support piece 531 is lifted upward by an external force, at which time the first clamping jaw U1 cooperates with the first inclined surface S1, and the first clamping jaw U1 can be switched to extend into the adjacent upper first groove 522 through the first inclined surface S1. After the upward external force is removed, the first clamping jaw U1 stays in the current first groove 522, improving the convenience of upward adjustment of the position of the tray 510 and achieving one-way locking of the first elastic lock 532 on the longitudinal Z position of the tray 510.

[0060] In some embodiments, the support piece 531 comprises a first mounting portion 5311. The first mounting portion 5311 is provided with a first opening K1. The first elastic lock 532 is mounted on the first mounting portion 5311 and located on the side of the first mounting portion 5311 away from the first grid structure. The first clamping jaw U1 can extend into the first groove 522 through the first opening K1. By providing the first mounting portion 5311, stable mounting of the first elastic lock 532 can be achieved, and by providing the first opening K1, it is ensured that the first clamping jaw U1 can smoothly extend into and exit the first groove 522.

[0061] In some embodiments, the first elastic lock 532 comprises a first rotating piece 5321 and a first elastic piece 5322. One end of the first rotating piece 5321 is the first clamping jaw U1. The first rotating piece 5321 is rotationally mounted on the first mounting portion 5311. The first elastic piece 5322 connects the first rotating piece 5321 and the first mounting portion 5311. In the state that the first rotating piece 5321 is not subjected to an external force, the first elastic piece 5322 causes the first rotating piece 5321 to turn so that the first clamping jaw U1 extends toward the first groove 522.

[0062] In the embodiment, the first rotating member 5321 and the first elastic member 5322 realize the one-way locking function of the first elastic lock 532 in a relatively simple structure, thereby ensuring the reliability of the use of the first elastic lock 532.

[0063] In some embodiments, the first rotating member 5321 further includes a first pressing portion R1. The first pressing portion R1 is arranged on the opposite side of the first rotating member 5321 from the first clamping jaw U1 and the rotating center of the first rotating member 5321. When the first pressing portion R1 is pressed by a first preset external force, the first clamping jaw U1 is caused to move away from the first groove 522. When the first pressing portion R1 is pressed by the first preset external force, the first rotating member 5321 rotates, the first clamping jaw U1 moves away from the first groove 522, and at this time, the first elastic lock 532 is unlocked, so that the tray 510 can be adjusted to a lower position along the first grid structure. By arranging the first pressing portion R1, the first elastic lock 532 can be unlocked by pressing the first pressing portion R1, thereby improving the convenience of the unlocking operation of the first elastic lock 532.

[0064] In some embodiments, the support member 531 further includes a second mounting portion 5312. The second mounting portion 5312 is located on the side of the first mounting portion 5311 away from the first grid structure, and has a containing space between the first mounting portion 5311 and the second mounting portion 5312, which can accommodate at least part of the first rotating member 5321. The second mounting portion 5312 is provided with a second opening K2, and at least part of the first pressing portion R1 is exposed from the second opening K2.

[0065] The first mounting portion 5311 can limit the rotating movement of the first rotating member 5321, so as to avoid the first elastic member 5322 from pushing the first rotating member 5321 to rotate excessively. By arranging the second opening K2 on the second mounting portion 5312, the convenience of the pressing operation of the first pressing portion R1 is improved.

[0066] In some embodiments, at least part of the surface of the first clamping jaw U1 facing the lower surface of the first protrusion 521 is a second inclined surface S2. In the embodiment, in the state that the first clamping jaw U1 extends into the first groove 522, the second inclined surface S2 of the first clamping jaw U1 is parallel to the first inclined surface S1 of the first protrusion 521, so that the two are adapted to each other.

[0067] In the embodiment, the entire lower surface of each first protrusion 521 is a first inclined surface S1 arranged obliquely relative to the horizontal plane. In some other embodiments, part of the lower surface of each first protrusion 521 is a first inclined surface S1 arranged obliquely relative to the horizontal plane. In the embodiment, the upper surface of each first protrusion 521 is parallel to the horizontal plane.

[0068] In some embodiments, the first inclined surface S1 is inclined at 15° to 75° relative to the horizontal plane, such that when the shelf 500 is only subjected to gravity, the friction between the first inclined surface S1 and the first claw U1 can achieve unidirectional locking of the first elastic latch 532 on the longitudinal Z position of the tray 510, and when the external force lifts the tray 510 or the support member 531 upward, the first claw U1 can slide over the first inclined surface S1.

[0069] In some embodiments, the support member 531 includes a crossbeam 5313. The shelf 500 also includes a second grid rail 540 and a second resilient latch 550.

Figure 11 for Figure 10 A partially enlarged schematic diagram of region A. A second grid guide rail 540 is mounted on a crossbeam 5313. The second grid guide rail 540 includes a second grid structure disposed along a first direction X, which is a transverse direction parallel to the printing surface 110. The second grid structure includes a plurality of second protrusions 541 arranged along the first direction X and second grooves 542 located between adjacent second protrusions 541. At least a portion of the same side surface of each second protrusion 541 is a third inclined surface S3 disposed relative to a first plane, which is a plane perpendicular to the first direction X. The tray 510 is connected to the support assembly 530 via the second grid guide rail 540, and the tray 510 is movable along the second grid structure.

[0071] The second elastic latch 550 includes a second claw U2 capable of extending into the second groove 542. The second elastic latch 550 is configured such that the second claw U2 extends into the second groove 542 under its own elastic force, and when the tray 510 is subjected to a unidirectional external force parallel to the first direction X, the second claw U2 can switch via the third inclined surface S3 to extend into the adjacent second groove 542.

[0072] In the state that the tray 510 is only subjected to gravity, the second clamping jaw U2 of the second elastic lock catch 550 can be clamped in the second groove 542, realizing the one-way locking of the tray 510 in the first direction X. In an example, the second elastic lock catch 550 realizes the locking of the tray 510 in the right movement in the first direction X, that is, when the second elastic lock catch 550 is not unlocked, the one-way locking of the second elastic lock catch 550 makes the tray 510 unable to move to the right, and when the tray 510 is driven to the left by an external force, the second clamping jaw U2 can be switched to extend into the adjacent left second groove 542 through the third inclined surface S3, and the second elastic lock catch 550 allows the tray 510 to move to the left. If it is prepared to move the tray 510 to the right, a specific external force needs to be applied to the second elastic lock catch 550 so that the second elastic lock catch 550 is unlocked. In the above example, the locking of the tray 510 in the right movement in the first direction X by the second elastic lock catch 550 is taken as an example for description, and in some other embodiments, the locking of the tray 510 in the left movement in the first direction X by the second elastic lock catch 550 can also be realized.
