[0024] In order to make the purpose of the utility model, the technical scheme and the advantage are more clear and obvious, the following combines the drawing and the implementation example, carries out the further detailed explanation to the utility model. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0025] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for the purpose of illustration only.

[0026] In inkjet printing technology, the ink receiving seal plate is a key component to ensure stable printing quality and equipment cleaning, responsible for collecting excess ink generated by the printhead, such as ink for test spraying before the printhead is in operation. However, the design of the ink receiving seal plate in the prior art has obvious deficiencies. In terms of seal position design, due to lack of sufficient accuracy and stability, the sealing effect is not good, and it is difficult to effectively prevent dust, paper scraps and other debris from entering the printhead, which not only affects the printing quality, but also increases the maintenance cost of the printhead. At the same time, frequent disassembly and assembly of the seal position can cause damage to the printhead, further increasing the difficulty of equipment maintenance. In addition, the ink receiving groove design also has the problem of limited capacity, due to unreasonable structure design, the ink receiving medium needs to be frequently replaced, which not only increases the labor and time cost, but also reduces the work efficiency. Therefore, improving the design of the ink receiving seal plate, enhancing the sealing effect, enhancing the stability and expanding the capacity of the ink receiving groove, has important significance for improving the printing quality and the convenience of equipment maintenance.

[0027] Referring to Figs. 1 to 3 The utility model embodiment provides a novel ink receiving seal plate for inkjet printhead 40, comprising:

[0028] The plate body 10 is rotatably arranged below the inkjet printhead 40, effectively improving the flexibility and adaptability of the ink receiving seal plate during use, and can perform sealing or unsealing operation according to the spraying and printing requirements. The plate body 10 is provided with ink receiving grooves 11 on the symmetrical two sides, which are used for collecting and storing excess ink to prevent ink overflow. The symmetrical design on the two sides meets the requirement of rotary switching and realizes the expansion of the ink receiving capacity of the ink receiving grooves 11. The ink receiving grooves 11 are provided with ink storage members 20, which can fully absorb and store excess ink to keep the printing environment clean. The two ink receiving grooves 11 are further provided with sealing positioning grooves 12 matched with the inkjet end of the inkjet printhead 40, which can ensure that the inkjet end of the inkjet printhead 40 is effectively sealed when not in use.

[0029] The elastic sealing gasket 30 is installed on the sealing positioning groove 12, improves the sealing effect, enhances the sealing stability, effectively prevents small sundries such as dust and paper scraps from entering the inside of the nozzle, and prolongs the service life of the nozzle.

[0030] In the embodiment, the plate body 10 is semicircular, effectively utilizes the space, and makes the structure compact. The ink receiving groove 11 is semicircular and matches the shape of the plate body 10, enhances the ink receiving effect, is distributed along the circumferential direction of the plate body 10, and has the same center as the plate body 10, thereby ensuring the uniformity and stability of ink receiving.

[0031] Further, the mounting hole 13 is arranged at the center of the plate body 10, facilitates the mounting and dismounting of the plate body 10, and is further provided with the arc-shaped through groove 14 between the mounting hole 13 and the ink receiving groove 11. The arc-shaped through groove 14 reduces the overall weight of the plate body 10, reduces the rotating power consumption, facilitates the observation of the ink jet operation, has the same center as the ink receiving groove 11, and further enhances the integrity and coordination of the design.

[0032] Further, the groove depth of the ink receiving groove 11 is greater than the thickness of the ink storage member 20, ensures that the ink storage member 20 can be completely embedded in the ink receiving groove 11, and facilitates the intuitive understanding of the ink storage limit of the ink storage member 20, thereby avoiding ink overflow.

[0033] The ink storage member 20 is any one of a sponge, a polyurethane foam and a gel ink absorbing pad, so as to provide good ink absorbing performance and durability.

[0034] The elastic sealing gasket 30 is a rubber sealing gasket, has good elasticity and sealing performance, and ensures the sealing effect of the sealing positioning groove 12.

[0035] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the principles of the present application shall be included in the protection scope of the present application.
