They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1-2 As shown in Figure 4, a preferred embodiment of this utility model provides a digital printing machine inkjet carriage, including a carriage body 1 and an inkjet mechanism 2 mounted on the carriage body 1. Powder spraying mechanisms 3 are provided on both sides of the inkjet mechanism 2. A UV curing mechanism is provided between the powder spraying mechanism 3 and the inkjet mechanism 2. A slider is provided on the rear side wall of the carriage body 1, and the slider is used to slide against the crossbeam of the printing machine. A drive assembly is connected to the slider and is used to drive the carriage body 1 to rise and fall relative to the slider. Specifically, the drive assembly is a lifting motor fixed to the outer wall of the carriage body 1. A lead screw is connected to the output shaft of the lifting motor, and the lead screw is threadedly connected to the slider, thereby driving the carriage body to rise and fall relative to the slider through the rotation of the lead screw. Simultaneously, because the slider drives the carriage body 1 to move laterally along the crossbeam, combined with the longitudinal movement of the crossbeam itself along the frame, a three-axis motion of the carriage body 1 relative to the printed material is achieved. The inkjet mechanism 2 is used for inkjet printing, and the powder spraying mechanism 3 is used for spraying glitter powder; both are existing structures and will not be described in detail here.

[0023] The trolley body 1 is also provided with a powder cleaning mechanism 4, which is located on one side of the powder spraying mechanism 3; or the powder cleaning mechanism 4 is located on the lower edge of the trolley body 1, arranged in a ring, surrounding the printing mechanism 2 and the powder spraying mechanism 3.

[0024] Based on the above-mentioned technical features, the digital printing machine inkjet carriage has a powder cleaning mechanism 4 set on the carriage body 1 and placed on one side of the powder spraying mechanism 3; or placed on the lower edge of the carriage body 1, surrounding the printing mechanism 2 and the powder spraying mechanism 3. When the powder spraying mechanism 3 sprays out glitter during the printing process, the powder cleaning mechanism 4 removes the excess glitter in time, thereby achieving the function of removing excess floating powder, avoiding floating powder adhering to the product, and ensuring the quality of the product.

[0025] As can be seen from the above, in this embodiment, the powder cleaning mechanism 4 has two configuration methods, specifically:

[0026] Example 1

[0027] like Figure 1-3 As shown, when the powder cleaning mechanism 4 is located on one side of the powder spraying mechanism 3, there are two powder cleaning mechanisms 4, respectively located between the printing mechanism 2 and the powder spraying mechanism 3. In this case, the powder cleaning mechanism 4 includes a powder suction cylinder 41, with a powder suction chamber 42 inside. The powder suction chamber 42 is used to connect to an air suction device. Specifically, the side wall of the powder suction cylinder 41 is provided with a powder discharge pipe 43 communicating with the powder suction chamber 42, and the other end of the powder discharge pipe 43 is used to connect to the air suction device. The lower end face of the powder suction cylinder 41 is provided with multiple air suction holes, which are connected to the powder suction chamber 42. During the printing process, when the powder spraying mechanism 3 sprays out glitter, the excess glitter is removed through the air suction holes by the air suction component, thereby achieving the function of removing excess floating powder, preventing floating powder from adhering to the product, and ensuring product quality.

[0028] In some embodiments, since the substrate is placed on the working platform of the printing press, some powder may adhere to the working platform during the actual powder spraying process. To remove this dust, multiple brushes 44 can be provided on the lower end face of the powder suction cylinder 41. Each brush 44 corresponds to one of the multiple air suction holes, with the air suction holes positioned between the corresponding brushes 44. That is, the brushes 44 sweep away the adhering dust, and then the suction device removes the dust through the air suction holes.

[0029] In addition, to ensure better dust removal, the powder suction cylinder 41 is equipped with a vibrating plate, and multiple brushes 44 are connected to the vibrating plate. Dust is removed by the vibration of the vibrating plate, such as a piezoelectric ceramic plate; or the brushes 44 can be rotated using a mechanical structure; or the brushes 44 can be driven to move with the powder spraying assembly by the moving mechanism of the powder spraying assembly to remove dust. Simultaneously, the powder suction cylinder 41 has air blowing chambers 45 extending to both ends in its middle. Air suction holes are evenly distributed around the center of the lower end face of the air blowing chamber 45, and the upper end of the air blowing chamber 45 is used to connect to an air blowing device. Therefore, when the powder spraying mechanism 3 sprays glitter during the printing process, the brushes 44 and the air blowing device start working, blowing away excess glitter through the air blowing device and sweeping it away by the vibration or rotation of the brushes 44. The dust is then sucked away by the air suction holes in the middle of the brushes 44, thus achieving the function of removing excess dust.

[0030] Example 2

[0031] like Figure 4As shown, when the powder cleaning mechanism 4 is located at the lower edge of the carriage body 1, the powder cleaning mechanism 4 includes a plurality of powder suction holes 46, which are connected to each other for connecting to an air suction device. The air suction device removes loose powder, ensuring that dust within the entire bottom area of ​​the carriage body 1 will not be ejected outside the printing carriage.

[0032] In addition, to further ensure the removal effect of floating powder, a number of the powder suction holes 46 are set to form a powder suction space. Then, a number of powder blowing holes 47 are set inside the powder suction holes 46 in the powder suction space, and the number of powder blowing holes 47 are connected to each other to connect to the blowing device. The adhering dust is blown up by the blowing device and then sucked away to ensure the removal effect.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
