Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0053] It should be noted that, in the present embodiment, the UV nozzle refers to a printer nozzle that uses ultraviolet (UV) curing ink and can print on various materials. The UV printer refers to a printer that uses ultraviolet (UV) curing ink and can print on various materials.

[0054] It should be noted that, in the present embodiment, the detachable connection can mean that the two components are directly detachably connected, that is, there is no intermediate element between the two components; or the detachable connection can mean that the two components are indirectly detachably connected, that is, at least one intermediate element is allowed to exist between the two components to achieve the detachable connection of the two components.

[0055] Referring to FIGS. 1-7, an embodiment of the present application provides a nozzle device, which comprises a quick-release assembly 10 and a printing moving assembly 20. The quick-release assembly 10 is detachably arranged on the printing moving assembly 20. The printing moving assembly 20 comprises a moving seat 21 and a first electrical connection joint 22 arranged on the moving seat 21. The moving seat 21 is arranged on a beam moving mechanism of a printer. The first electrical connection joint 22 is electrically connected with a controller. Optionally, the controller is provided with an electrical connection member 30. The electrical connection member 30 comprises but is not limited to a transmission line for transmitting electrical signals, such as a flexible flat cable. In addition, the electrical connection member 30 is electrically connected with the first electrical connection joint 22. The connection mode of the first electrical connection joint 22 and the electrical connection member 30 comprises but is not limited to welding connection, clamping connection, connection and fixation by using various conductive fasteners such as pins, rivets, screws, connection and fixation by using conductive adhesive tape, or connection and fixation by using conductive adhesive, etc. The specific connection mode can be flexibly adjusted and set according to actual needs.

[0056] Specifically, the quick-release assembly 10 comprises a bracket 11, a UV nozzle 12, an ink capsule 13, and a second electrical connection joint 14. The bracket 11 is arranged on the printing moving assembly 20 in a detachable manner. The UV nozzle 12 is arranged on the bracket 11. When the bracket 11 is arranged on the printing moving assembly 20, the printing moving assembly 20 can drive the bracket 11 to move, thereby driving the UV nozzle 12 arranged on the bracket 11 to move, so as to complete the printing work of the UV nozzle 12.

[0057] In addition, the ink capsule 13 is arranged on the bracket 11. An ink inlet of the ink capsule 13 is arranged in a detachable manner with an ink cartridge assembly.

The quick-release assembly 10 can be detached from the printing moving assembly 20.

[0059] Since the nozzle device comprises the quick-release assembly 10 and the printing moving assembly 20, the printing moving assembly 20 is provided with a moving seat 21 and a first electric connection joint 22 electrically connected with a controller, the UV nozzle 12, the ink capsule 13 and a second electric connection joint 14 are arranged on the support 11, and the support 11 is detachably arranged on the printing moving assembly 20, so that the quick-release assembly 10 is detachably connected with the printing moving assembly 20; in addition, the ink inlet part of the ink capsule 13 is detachably connected with the ink box assembly, and the second electric connection joint 14 is detachably connected with the first electric connection joint 22, so that when the UV nozzle 12 needs to be maintained due to failure, the ink inlet part and the ink box assembly are disassembled, the second electric connection joint 14 and the first electric connection joint 22 are disassembled, and then the quick-release assembly 10 is disassembled from the printing moving assembly 20, so that the UV nozzle 12 can be maintained, which has smaller disassembly workload, can facilitate maintenance, and has higher maintenance efficiency compared with the prior art.

[0060] Please refer to FIGS. 1-3, in an embodiment, the moving seat 21 is formed with a receiving groove 211. The support 11 is slidably inserted into the inside of the receiving groove 211. When the support 11 is inserted into the inside of the receiving groove 211, the support 11 is connected and fixed with the printing moving assembly 20, specifically connected and fixed with the moving seat 21. In this way, since the support 11 is inserted into the receiving groove 211 by sliding, the disassembly and assembly of the quick-release assembly 10 on the printing assembly can be facilitated; in addition, after the quick-release assembly 10 is installed, the quick-release assembly 10 is located in the inside of the receiving groove 211, and the support 11 is connected and fixed with the printing moving assembly 20, so that the quick-release assembly 10 can be stably arranged on the printing moving assembly 20.

[0061] Please refer to FIGS. 1-3, in an embodiment, the support 11 is provided with a first clamping part 111, which is used for clamping cooperation with a second clamping part 212 on the printing moving assembly 20. Specifically, the second clamping part 212 is arranged on the moving seat 21. When the support 11 is inserted into the inside of the receiving groove 211, the first clamping part 111 and the second clamping part 212 are clamped with each other to connect and fix the support 11 with the printing moving assembly 20. In this way, by slidingly inserting the quick-release assembly 10 into the inside of the receiving groove 211 of the printing moving assembly 20, and clamping the first clamping part 111 with the second clamping part 212 after being inserted in place, the connection and fixation of the support 11 with the printing moving assembly 20 are realized, which, compared with the screw disassembly and assembly mode, eliminates the cumbersome steps of disassembling and assembling screws, and greatly improves the disassembly and assembly efficiency and operation experience of the quick-release assembly 10.

[0062] Specifically, the first clamping part 111 comprises a first presser 1111 which can be pressed and a first clamping block 1112. The first presser 1111 is connected to the outer periphery of the bracket 11, and the first clamping block 1112 is connected to the first presser 1111. The first clamping part 111 includes but is not limited to being located on the top wall, the bottom wall or the left and right two side walls of the bracket 11, and the specific implementation is not limited herein. The second clamping part 212 is specifically provided on the mouth wall of the insertion opening of the accommodating groove 211 for the insertion of the bracket 11. Alternatively, the insertion opening is formed on one side of the accommodating groove 211, so that the quick release assembly 10 is inserted into the interior of the accommodating groove 211 from one side of the accommodating groove 211 and in the horizontal direction, and after being inserted into the interior of the accommodating groove 211, it is stably supported by the jet printing moving assembly 20. In addition, the first presser 1111 includes but is not limited to a presser plate, a presser strip or a presser block which is arranged at an angle with the outer wall of the bracket 11, one end of the first presser 1111 is connected to the bracket 11, and the other end is a free end. When the free end is pressed, the first presser 1111 can drive the first clamping block 1112 to move to separate from the second clamping part 212, so that the quick release assembly 10 can be pulled out from the jet printing moving assembly 20, and the quick release is achieved. Therefore, the quick release assembly 10 can be stably and quickly assembled to the jet printing moving assembly 20, and the quick release assembly 10 can be quickly disassembled from the jet printing moving assembly 20, thereby improving the maintenance efficiency of the UV jet head 12.

[0063] Alternatively, the number of the first clamping part 111 and the second clamping part 212 is one, two or other numbers, which is not limited herein and can be flexibly adjusted and set according to actual needs.

[0064] Of course, in some optional solutions, the bracket 11 is not limited to being provided with the first clamping part 111, and the jet printing moving assembly 20 does not need to be provided with the second clamping part 212, but for example, after the bracket 11 is inserted into the accommodating groove 211, various fasteners such as positioning pins, screws, straps and ropes are used to connect and fix the quick release assembly 10 and the jet printing moving assembly 20, and the specific implementation can be flexibly selected and set according to actual needs, which is not limited herein.

[0065] Please refer to FIG. 1, FIG. 3, FIG. 5, FIG. 6, FIG. 8 and FIG. 9, in one embodiment, the first electrical connection 22 includes a first plug-in part 221. The second electrical connection 14 includes a second plug-in part 141. The second plug-in part 141 is plug-in matched with the first plug-in part 221. The plug-in direction of the second plug-in part 141 is the same as the insertion direction S of the bracket 11 inserted into the accommodation groove 211, when the bracket 11 is inserted into the accommodation groove 211, the second plug-in part 141 is inserted into the first plug-in part 221 at the same time. In this way, when the quick release assembly 10 is pulled out from the inside of the accommodation groove 211, the second plug-in part 141 will be separated from the first plug-in part 221 at the same time, so as to realize the disconnection of the second electrical connection 14 and the first electrical connection 22, that is, the disconnection of the second electrical connection 14 and the controller, and the electrical disconnection can be realized quickly; on the contrary, when the quick release assembly 10 is inserted into the accommodation groove 211 through the insertion port, the second plug-in part 141 will be inserted into the first plug-in part 221 at the same time, so as to realize the electrical connection of the second electrical connection 14 and the first electrical connection 22, that is, the connection of the second electrical connection 14 and the controller, and it can be seen that the electrical connection can be realized quickly.

[0066] It should be noted that the specific setting form of the second plug-in part 141 and the first plug-in part 221 is more, including but not limited to the matching form of the gold finger 1411 and the slot 2211, the matching form of the USB connector and the USB interface, the matching form of the electrical plug and the electrical socket, etc., and the specific setting can be adjusted flexibly according to the actual demand, which will not be listed one by one. In one example, one of the second plug-in part 141 and the first plug-in part 221 is provided with a gold finger 1411, and the other is provided with a slot 2211 matched with the gold finger 1411, and the gold finger 1411 inserted into the slot 2211 can realize the mutual docking and communication of the second plug-in part 141 and the first plug-in part 221. On the contrary, when the gold finger 1411 is pulled out from the inside of the slot 2211, the second plug-in part 141 and the first plug-in part 221 are separated from each other. In another example, one of the second plug-in part 141 and the first plug-in part 221 is provided with a USB connector, and the other is provided with a USB interface matched with the USB connector, and the USB connector inserted into the USB interface can realize the mutual docking and communication of the second plug-in part 141 and the first plug-in part 221. On the contrary, when the USB connector is pulled out from the inside of the USB interface, the second plug-in part 141 and the first plug-in part 221 are separated from each other.

[0067] In this embodiment, in order to save the occupied space and cost, the second plug-in part 141 and the first plug-in part 221 are respectively provided with a gold finger 1411 and a slot 2211 and adopt the form of mutual plug-in cooperation. In addition, the gold finger 1411 and the slot 2211 realize the electrical connection of the second electrical connection joint 14 and the first electrical connection joint 22 in the form of mutual plug-in, avoiding the cumbersome and inconvenient plugging of the wire harness when replacing the UV nozzle 12.
