[0002] With the continuous improvement and innovation of modern production and printing technology, industrial printers, as emerging printing and publicity equipment, are environmentally friendly, cheap, and can print a wide variety of media materials, so there are many consumer groups and a wide range of sales outlets. Usually, during the printing process, a nozzle cleaning device is required to wipe and clean the print head. At present, the nozzle cleaning device of an inkjet printer generally has an ink pad and a scraper installed in parallel. When the nozzle needs to be cleaned, the scraper does not move, and the nozzle moves to the top of the scraper for cleaning, or the nozzle does not move, and the scraper moves horizontally to scrape and clean the nozzle. Therefore, the specific structure and installation position of the ink stack and the scraper directly affect the moisturizing and cleaning effect of the nozzle.

[0003] For example, the utility model patent application with the authorization announcement number CN219856489U specifically discloses a split multi-head lifting ink stack and industrial printer, including an ink stack bottom plate, on which at least two groups of ink stack groups can be lifted and lowered. A lifting mechanism is separately provided at the bottom of each group of ink stack groups; the ink stack group includes a storage base connected to the ink stack bottom plate, and a lifting support seat that can be lifted and lowered in the storage base, and a top plate is provided on the top of the lifting support seat, and a plurality of ink absorbing pads and scrapers are provided on the top plate; the lifting mechanism includes a driving motor located at the bottom of the ink stack bottom plate, a ball screw connected to the driving motor, and a guide column that slides with the bottom of the lifting support seat, and the ball screw is connected to the bottom of the lifting support seat. The device can perform separate lifting adjustment and maintenance of a single ink stack group, but the split multi-head lifting ink stack has high requirements for installation space, the lifting support point is small, and it cannot realize the functions of automatic and manual lifting operations at the same time.

[0023] This embodiment provides an ink stack assembly, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it comprises a base plate 1, one end of which is provided with a driving motor 14. A lead screw 15 is connected to the main shaft of the driving motor 14, the other end of which is connected to a manual knob 8, and a lead screw nut 16 is provided on the lead screw 15.

[0024] like Figure 6 and Figure 7As shown, the lead screw nut 16 is connected to a nut mounting plate 17, and the nut mounting plate 17 is connected to a forward and backward motion base plate 20. Vertical forward and backward drive plates 19 are arranged on both sides of the forward and backward motion base plate 20, and oblique guide holes 18 are respectively opened at the front and rear ends of the vertical forward and backward drive plates 19.

[0025] A pair of vertical fixing plates 7 are disposed on the bottom plate 1 . The vertical forward and backward driving plate 19 is located between the pair of vertical fixing plates 7 , and vertical guide holes 13 are formed on the vertical fixing plates 7 at locations corresponding to the oblique guide holes 18 .

[0026] A pair of ink stack lifting support plates 9 are provided on the outer side of the vertical fixed plate 7 so as to be liftable, and a fixing seat 3 is installed between the tops of the pair of ink stack lifting support plates 9. An ink stack mounting plate 4 is installed on the fixing seat 3, and an ink stack 6 and a scraper 5 are installed on the ink stack mounting plate 4.

[0027] The ink stack lifting support plate 9 is provided with a first guide pin 12 corresponding to the vertical guide hole 13 , and the inner end of the first guide pin 12 passes through the vertical guide hole 13 and then slidably cooperates with the oblique guide hole 18 .

[0028] In this embodiment, in order to enable the forward and backward motion bottom plate to move forward and backward smoothly, a pair of forward and backward guide holes 11 are opened on the lower side of the vertical fixing plates 7. The vertical forward and backward driving plates 19 are provided with second guide pins 22 corresponding to the forward and backward guide holes 11, and the second guide pins 22 are slidably matched with the forward and backward guide holes 11.

[0029] Specifically, the oblique guide hole is arranged obliquely downward from top to bottom along one end of the driving motor toward one end of the manual knob.

[0030] Example 2

[0031] The present embodiment provides an ink stack assembly, which is mainly different from Embodiment 1 in that, in the present embodiment, in order to ensure the stability of the lead screw during rotation, a bearing seat 21 is provided on the bottom plate, and one end of the lead screw is rotatably matched with the bearing seat through a bearing.

[0032] In order to reduce friction, the forward and backward movement bottom plate is suspended above the bottom plate. In order to smoothly lift and lower, the four oblique guide holes are parallel to each other, and the inclination angles of the four oblique guide holes are the same.

[0033] Example 3

[0034] The present embodiment provides an ink stack assembly, which is mainly different from the embodiment 1 in that, in the present embodiment, in order to ensure smooth lifting and lowering, the four oblique guide holes are parallel to each other, and the inclination angles of the four oblique guide holes are the same.

[0035] The ink stack mounting plate and the bottom plate are also provided with guide pillars 2. A proximity switch 10 is also provided between the ink stack lifting support plate and the bottom plate.

[0036] Example 4

[0037] This embodiment provides an industrial printer equipped with the ink stack assembly described in Embodiment 1, Embodiment 2 or Embodiment 3.

[0038] Specifically, during the initial installation, when the front-rear moving bottom plate moves to one side of the driving motor, the oblique guide hole corresponds to the bottom of the vertical guide hole, and the fixing seat is in a descending state at this time. The inner end of the first guide pin passes through the bottom of the vertical guide hole and then slides with the oblique guide hole. As the lead screw rotates, the vertical front-rear driving plate and the front-rear moving bottom plate are driven to move toward one end. During the movement, the oblique guide hole pushes the first guide pin to gradually rise along the oblique guide hole. Due to the limitation of the vertical guide hole on the vertical fixing plate, when the oblique guide hole lifts the first guide pin, the first guide pin will rise vertically along the vertical guide hole, thereby realizing the change of the front-rear movement of the front-rear moving bottom plate into the vertical lifting movement of the ink stack lifting support plate.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
