The wiping device 10 according to the embodiment of the present invention includes a wiping mechanism 100, a driving mechanism 120, and an adjusting mechanism 140, wherein the adjusting mechanism 140 can be understood by referring to the combination of the contact member 142 and the elastic member 144 illustrated in fig. 1, 2, and 3. The ink scraping mechanism 100 is suitable for scraping ink, the driving mechanism 120 drives the ink scraping mechanism 100 to move, and the adjusting mechanism 140 adjusts and optimizes the ink scraping effect by controlling the compression amount of the scraper component 102 of the ink scraping mechanism 100 to be kept constant in the ink scraping operation.

The embodiment of the utility model provides a wiping mechanism 100 and actuating mechanism 120 set up from top to bottom, and wiping mechanism 100 specifically includes scraper component 102 and a supporting bench 104, and a supporting bench 104 is connected with actuating mechanism 120, and scraper component 102 sets up on a supporting bench 104 and is connected with a supporting bench 104. Thus, the drive mechanism 120 is capable of driving the squeegee mechanism 100, including the squeegee assembly 102 and the support platform 104, up and down in the longitudinal direction to move the squeegee assembly 102 toward and away from the nozzle assembly 20 of the inkjet printing apparatus.

Embodiments of the present invention provide a doctor assembly 102 having a blade head 110 and a blade holder 112. The tool bit 110 is mounted on a tool holder 112, and the tool holder 112 supports and fixes the tool bit 110. In some preferred embodiments of the present invention, the cutter head 110 is made of an elastic material, such as a rubber material.

The embodiment of the present invention provides a support platform 104 formed as a rectangular parallelepiped structure or a truncated cone structure, the upper surface of which is formed with a support surface parallel to the horizontal plane, and a scraper assembly 102 is disposed on the support surface.

In some preferred embodiments of the present invention, the driving mechanism 120 is a cylinder driving mechanism, which can ensure the stability of the ink scraping mechanism 100 in the moving process and the accuracy of the moving position, and has simple structure and low cost, and is suitable for mass production.

The embodiment of the utility model provides a wiping arrangement 10 scrapes the china ink operation to shower nozzle subassembly 20 through following mode:

firstly, the driving mechanism 120 drives the ink scraping mechanism 100 to move vertically upwards until the position of the ink scraping mechanism 100 is kept fixed after the ink scraping mechanism 100 moves to a specified position, and at the moment, the cutter head 110 of the scraper component 102 is close to the spray head component 20;

subsequently, the nozzle assembly 20 is gradually moved in a horizontal direction from one side of the blade assembly 102 to the other side over the blade assembly 102 until all of the nozzles on the nozzle assembly 20 pass the blade assembly 102, so that the cutter head 110 scrapes off ink droplets passing over each of the nozzles above it;

finally, the spray head assembly 20 is reset, the driving mechanism 120 drives the ink scraping mechanism 100 to vertically move downwards, until the position of the ink scraping mechanism 100 is kept fixed again after the ink scraping mechanism 100 travels to the designated position, at this time, the cutter head 110 of the scraper assembly 102 is far away from the spray head assembly 20, and the ink scraping operation is finished.

During the movement of the head assembly 20, the ink droplets collected at the heads and/or the heads 110 contact to form a wiping operation surface, which is the actual contact surface formed by the heads and/or the ink droplets collected at the heads contacting the surface of the head 110 of the blade assembly 102.

Further, during movement of the head assembly 20, the cutter head 110 is compressed by the force of the heads in contact therewith and/or the ink droplets collected at the respective heads, and generates a compression amount. When the volume of the ink droplets gathered at each nozzle is larger, or the contact area between the cutter head 110 and the nozzle and/or the ink droplets gathered at each nozzle is larger, or the traveling speed of the nozzle and/or the ink droplets gathered at each nozzle is faster, the cutter head 110 is compressed to a larger extent, that is, the compression amount is larger, and vice versa, the compression amount is smaller.

Due to the influence of various factors such as the smoothness of the head assembly 20 during the moving process and the smoothness of the place where the inkjet printing device is placed, and the shape and size of the ink droplets collected at each head are different, the compression amount of the cutter head 110 during the ink scraping operation may be changed, and the change of the compression amount of the cutter head 110 may have an adverse effect on the ink scraping effect, such as damage to the head due to too large compression amount of the cutter head 110, or incomplete ink scraping due to too small compression amount of the cutter head 110.

Therefore, in order to avoid the compression amount of the cutter head 110 from changing and ensure the ink scraping effect, the ink scraping device 10 provided by the embodiment of the present invention further includes the adjusting mechanism 140. The adjustment mechanism 140 functions to ensure that the amount of compression of the cutting head 110 during the wiping operation is constant.

Specifically, the adjustment mechanism 140 receives a force from the head assembly 20 during the wiping operation, and adjusts the wiping operation surface of the doctor blade assembly 102 accordingly according to the direction and/or magnitude of the force, so that the amount of compression of the doctor blade assembly 102 during the wiping operation remains constant.

In some embodiments of the present invention, a portion of the adjustment mechanism 140 may be in contact with the head assembly 20 during the wiping operation, while another portion of the adjustment mechanism 140 is configured to be elastic, and the portion of the adjustment mechanism 140 with elasticity is used to support the doctor assembly 102. The adjustment mechanism 140 may be directly coupled to the portion of the nozzle assembly 20 that contacts the flexible portion or indirectly coupled to the flexible portion via other components such as the doctor assembly 102. Thus, when the portion of the adjusting mechanism 140 in contact with the head assembly 20 is subjected to a force from the head assembly 20 during the wiping operation, the force can be directly or indirectly transmitted to the portion of the adjusting mechanism 140 having elasticity, and the portion of the adjusting mechanism 140 having elasticity is elastically deformed after being subjected to the force, and causes a slight change in the position or angle of the doctor blade assembly 102 supported by the portion of the adjusting mechanism 140 having elasticity, which causes the wiping operation surface of the doctor blade assembly 102 to be adjusted accordingly, and since the wiping operation surface is always adjusted in real time and synchronously in accordance with the state of the head assembly 20, the amount of compression of the doctor blade assembly 102 during the wiping operation can be kept constant. In summary, the provision of the adjustment mechanism 140 can improve the wiping effect and protect the head of the inkjet printing apparatus.

Specifically, the contact member 142 receives a force from the head assembly 20 during the wiping operation due to contact with the head assembly 20. Because the contact member 142 is coupled to the doctor assembly 102, the doctor assembly 102 is indirectly subjected to forces from the showerhead assembly 20. The elastic member 144 is disposed between the blade assembly 102 and the support base 104 and supports the blade assembly 102, so that when the blade assembly 102 is acted by a force, the elastic member 144 supporting the blade assembly is elastically deformed, and the elastic deformation of the elastic member 144 causes a slight change in the position or angle of the blade assembly 102 supported by the elastic member 144, thereby adjusting the ink-scraping operation surface of the blade assembly 102 accordingly.
