[0041] 800 Mounting Plate DETAILED DESCRIPTION

[0042] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0043] The embodiments of the present application provide a press-type quick-change nozzle assembly (hereinafter sometimes referred to as a "nozzle assembly") and a printing device.

[0044] See also Figure 1 The nozzle assembly may include a nozzle module 100 and a mounting base 500 , and the nozzle module 100 is used to be detachably mounted in the mounting base 500 .

[0045] Further, see Figure 2 The nozzle module 100 may include a nozzle 210 and a nozzle mounting seat 220 . The nozzle 210 is mounted in the nozzle mounting seat 220 . The nozzle 210 can be moved by moving the nozzle mounting seat 220 .

[0046] See also Figure 2 , Figure 3 The nozzle module 100 may further include a first pressing plate 300 hinged to the nozzle mounting seat 220. In a direction system consisting of mutually perpendicular X, Y, and Z directions, the rotation axis of the first pressing plate 300 is parallel to the X direction. In the Z direction, an elastic member 400 is disposed between the first pressing plate 300 and the nozzle mounting seat 220.

[0047] See also Figure 1, the mounting base 500 may include a mounting frame 610, and the nozzle module 100 can be loaded into the mounting frame 610 along the Y direction. Among them, the nozzle mounting seat 220 can abut against the mounting frame 610 in the X direction and the Z direction, and the first pressing plate 300 abuts against the mounting frame 610 in the Z direction. Exemplarily, the bottom of the nozzle mounting seat 220 can abut against the mounting frame 610, and the top of the first pressing plate 300 can abut against the mounting frame 610, so that the nozzle module 100 can be positioned in the X direction and the Z direction. It can be understood that the present application can ensure the accurate positioning of the nozzle mounting seat 220 in the X direction and the Z direction by matching the outer dimensions of the nozzle mounting seat 220 with the outer dimensions of the mounting frame 610.

[0048] See also Figure 4 , Figure 5 , Figure 6 , the first pressing plate 300 can be provided with a card slot 310, and the mounting frame 610 can be provided with a clamping piece 620. When the nozzle module 100 extends into the mounting frame 610 along the Y direction, the clamping piece 620 can be clamped in the card slot 310 to realize the positioning of the nozzle module 100 in the Y direction. Combined with the aforementioned first pressing plate 300, by pressing the first pressing plate 300, the card slot 310 can be moved in a direction away from the clamping piece 620, so that the nozzle module 100 can be taken out, thereby realizing the rapid disassembly and assembly of the nozzle module 100. The disassembly and assembly process can be carried out manually without the aid of additional tools, and the efficiency is relatively high. The movement trajectory of the nozzle mounting seat 220 is simple, and the replacement is easy. There are fewer positioning variables introduced during replacement, and it is easier to ensure the positioning accuracy.

[0049] Regarding the nozzle 210 and the nozzle mounting seat 220 , in one example, a step hole may be provided in the nozzle mounting seat 220 , and the nozzle 210 may include a radial positioning portion cooperating with the step hole to achieve radial fixation of the nozzle 210 .

[0050] For the hinged connection between the first pressing plate 300 and the nozzle mounting seat 220, see Figure 3 In one example, the top surface of the nozzle mounting seat 220 has a hinge portion 221, and the end of the first pressing plate 300 can be hinged to the hinge portion 221 by, for example, a pin.

[0051] Regarding the elastic member 400 of the first pressing plate 300, the elastic member 400 may be formed as a spring pin for resetting, a gas spring, a metal spring, etc. Figure 2 In one example, the elastic member 400 is formed as a spring pin for resetting. A mounting hole 222 (e.g., a threaded hole) is provided in the nozzle mounting seat 220. The spring pin for resetting is installed in the mounting hole 222, and its compressible pin head 410 for resetting is exposed. The pin head 410 for resetting can be pressed against the bottom of the first pressing plate 300 to reset (or push open) the first pressing plate 300.

[0052] Regarding the positions of the card slot 310 and the card connector 620, the positions of the card slot 310 and the card connector 620 in the first pressure plate 300 and the mounting frame 610 can be replaced (not shown in the figure). For example, the first pressure plate 300 can be provided with the card connector 620 without the card slot 310, and the mounting frame 610 can be provided with the card slot 310 without the card connector 620.

[0053] For the form of the clip 620, see Figure 6 In one example, the clamping member 620 can be formed as a clamping spring pin, which can include a clamping spring pin body 621 and a clamping pin head 622 elastically connected to the clamping spring pin body 621. The clamping pin head 622 (for example, formed as a spherical head) is compressed and contracted before being aligned with the slot 310. After the clamping pin head 622 is aligned with the slot 310, the clamping pin head 622 pops up and extends into the slot 310 under the action of elasticity. The clamping process will make a "click" sound, which can be used to feedback to inform the operator that the installation is in place, and has a good human-computer interaction experience.

[0054] For the installation position of the clamping member 620, see Figure 2 In one example, a clip-on mounting groove 611 may be provided in the mounting frame 610, and a clip-on spring pin body 621 may be fixedly provided in the clip-on mounting groove 611, for example, by a threaded connection.

[0055] For the first pressing plate 300, see Figure 6 In one example, the nozzle mounting seat 220 includes a pressure plate groove 230. When the clamping member 620 is clamped into the clamping groove 310, there is a gap between the first pressure plate 300 and the bottom of the pressure plate groove 230, so that the first pressure plate 300 can rotate.

[0056] See also Figure 3 The first pressing plate 300 includes a pressing area 320. The aforementioned clamping groove 310 is disposed between the pressing area 320 and the rotating shaft 350 of the first pressing plate 300. The elastic member 400 and the clamping member 620 are located at the upper and lower sides of the first pressing plate 300.

[0057] When the clamping member 620 is inserted into the clamping slot 310, an angle is formed between the plane formed by the X direction and the Y direction and the surface where the pressing area 320 is located, and the pressing area 320 is raised. For example, it is easy to hold. The angle can be 0-5°, for example, 3°.

[0058] Further, see Figure 4 , Figure 5, a transition section 340 with a gradually changing height may be provided at the front side of one end of the first pressing plate 300 close to the card slot 310. The transition section 340 is formed as a side wall of the card slot 310. The height of the transition section 340 increases as it approaches the card slot 310. After the first pressing plate 300 extends into the installation frame 610, the transition section 340 first contacts the card pin head 622 for card connection, so that the card pin head 622 for card connection is gradually compressed and can be released at the card slot 310.

[0059] See also Figure 3 The nozzle module 100 may further include a second pressing plate 330 fixedly connected to the nozzle mounting seat 220. After the first pressing plate 300 is rotated, the pressing area 320 can rotate toward the second pressing plate 330. For example, the first pressing plate 300 and the second pressing plate 330 may be pinched with the thumb and index finger in opposite directions to realize the downward rotation of the first pressing plate 300 so as to take out the nozzle module 100. The second pressing plate 330 is provided to facilitate the operator to apply force and make the operation easier.

[0060] See also Figure 2 and Figure 7 The nozzle mounting seat 220 may be provided with a first magnetic connector 710, and the mounting base 500 may be provided with a second magnetic connector 720. When the clamping member 620 is inserted into the clamping slot 310, the first contact 711 of the first magnetic connector 710 may be magnetically attracted and electrically connected to the second contact 721 of the second magnetic connector 720. The magnetic force may further improve the connection strength and avoid deviation.

[0061] In one example, one of the first contact 711 and the second contact 721 is formed as a protruding structure, and the other is formed as a recessed structure. The protruding structure can extend into the recessed structure to further play a positioning role. Exemplarily, the first contact 711 can be formed as a protruding structure, and the second contact 721 is correspondingly formed as a recessed structure.

[0062] See also Figure 2 and Figure 7 The nozzle mounting seat 220 and the mounting base 500 are more specifically a mounting plate, and corresponding mounting holes of the first magnetic connector 710 and the second magnetic connector 720 can be set as described later, and the first magnetic connector 710 and the second magnetic connector 720 are fixedly set in their mounting holes.

[0063] The nozzle 210 can be electrically connected to the first contact 711 of the first magnetic connector 710, wherein the electrical connection can be embodied as welding of the wire and the contact. Then the circuit in the nozzle 210 can be connected to an external circuit (e.g., a related circuit of a printing device) through the second magnetic connector 720. When the two magnetic connectors are connected and disconnected, the circuit is connected and disconnected. The method of connecting the magnetic connector reduces the risk of damage to the existing nozzle 210 due to frequent plugging and unplugging of the circuit.

[0064] See also Figure 8 The mounting base 500 may further include a mounting plate 800, the mounting frame 610 may be integrally formed with the mounting plate 800, or the mounting frame 610 may be fixed to the mounting plate 800, and the mounting plate 800 may be connected to a relevant position of, for example, a printing device by bolts. The mounting plate 800 has a strong form compatibility and is convenient for adapting to the needs of various printing devices. The holes for bolt connection on the mounting plate 800 may be countersunk holes.

[0065] The printing device provided in the present application may include the press-type quick-change nozzle assembly as described above.

[0066] Advantages of this application include:

[0067] (1) The nozzle module 100 is easy to take in and out. After the thumb and index finger pinch the first pressing plate 300 and the second pressing plate 330, the elastic member 400 is compressed, and the first pressing plate 300 rotates downward. At this time, the nozzle module 100 can be taken out. On the contrary, align the nozzle module 100 with the installation frame 610 of the installation base 500 and push it inward. When a "click" sound is heard, it means that it is installed in place.

[0068] (2) Precise positioning. The dimensions of the nozzle 210 fixing base are closely matched with the mounting frame 610, ensuring that each installation is completed in the same position without movement in the X or Z direction. The matching between the clamping member 620 and the clamping slot 310 enables precise positioning in the Y direction.

[0069] (3) Easy installation and maintenance. In the existing design, when removing the nozzle 210, the power cord on the nozzle 210 needs to be disconnected from the device. However, the present application arranges the line connection on the contact point of the magnetic connector, and the circuit is connected through the cooperation of the two magnetic connectors, eliminating the need for repeated wiring.

[0070] If the nozzle 210 needs to be maintained, the first pressing plate 300 can be rotated and lifted up while the nozzle module 100 is removed, and the nozzle 210 can be tightened, cleaned, and other related operations can be performed accordingly.

[0071] (4) Strong compatibility. The nozzle assembly is connected to the printing device through the mounting plate. The connection relationship is simple, and it is feasible to assemble different devices and has strong compatibility.

[0072] The above are preferred implementations of the present application. It should be pointed out that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as within the scope of protection of the present application.
