It is expressly intended that all such similar substitutes and modifications which would be obvious to one skilled in the art are deemed to be included in the invention. While the methods and applications of this invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the methods and applications described herein, as well as other suitable variations and combinations, may be made to implement and use the techniques of this invention without departing from the spirit and scope of the invention.
The applicant researches and discovers that: the prior art is provided with few coating devices for adjusting the thickness of the ink layer according to the thickness of the plate. The amount of spray is typically determined by image capturing the thickness of the sheet, if any. This is not only a tedious procedure, but also costly.
Accordingly, embodiments of the present invention provide an ink application apparatus adaptive to plate thickness, as shown in fig. 1 and 2. The apparatus comprises: the device comprises a frame 1, wherein an upper compression roller 2 is arranged at the lower end of the frame 1, a pressure supply groove 3 is arranged above the upper compression roller 2, a bottom plate of the pressure supply groove 3 is a movable bottom plate and is in contact with the upper compression roller 2, a first liquid is filled in the pressure supply groove 3 and is used for providing pressure for the upper compression roller 2, a liquid storage chamber 4 is arranged on the side of the pressure supply groove 3, and a lifter 5 for lifting the bottom plate of the liquid storage chamber 4 is arranged below the liquid storage chamber 4; an application roller 6 is provided below the upper press roller 2, and an ink tank 7 for loading ink is provided below the application roller 6.
When the plate to be coated enters the gap between the upper press roll 2 and the coating roll 6, the upper press roll 2 moves upwards to jack up the bottom plate of the pressure supply groove 3, so that the first liquid in the pressure supply groove 3 flows into the liquid storage chamber 4, and the pressure supplied by the pressure supply groove 3 to the upper press roll 2 is reduced.
When the plate to be coated is coated, the coating thickness is increased as the pressure applied to the plate is decreased. When the plate to be coated enters the gap between the upper press roll 2 and the coating roll 6, the upper press roll 2 is pushed upwards by the thickness of the plate to be coated, and the upward movement height of the upper press roll 2 is consistent with the thickness of the plate to be coated. The upper press roll 2 moves upwards to drive the bottom plate of the pressure supply groove 3 to move, so that the first liquid in the pressure supply groove 3 flows into the liquid storage chamber 4. The thicker the plate to be coated, the more the bottom plate of the pressure supply groove 3 is jacked up, the less the first liquid in the pressure supply groove 3, so that the pressure of the pressure supply groove 3 on the upper pressure roller 2 is smaller, the pressure to which the plate to be coated is subjected in the gap between the upper pressure roller 2 and the coating roller 6 is smaller, and the thicker the ink layer to be coated is.
When the sheet to be coated leaves the gap between the upper press roll 2 and the coating roll 6, the elevator 5 lifts the bottom plate of the liquid storage chamber 4, so that the first liquid in the liquid storage chamber 4 flows into the pressure supply groove 3, and the pressure supplied by the pressure supply groove 3 to the upper press roll 2 is increased.

Optionally, a first feed opening is arranged on the ink tank 7, the first feed opening is connected with a feed pipe, and the first feed opening is used for adding ink to the ink tank 7. The ink can be added through the feed inlet in the working process of the equipment, so that the number of times of adding in a halt mode is reduced, the working time is prolonged, and the coating efficiency is improved.
Optionally, the pressure supply tank 3 and the liquid storage chamber 4 share a side wall, and the side wall of the pressure supply tank 3 cannot move along with the bottom plate of the pressure supply tank 3 and is always maintained at the original height.
It should be noted that, the shared side wall can reduce the use of raw materials, reduce production cost, and also can ensure that the pressure supply tank 3 is closely attached to the liquid storage chamber 4, and leakage is generated when the pressure supply tank 3 and the liquid storage chamber 4 discharge first liquid mutually. The original height of the side wall is maintained to ensure that the pressure supply tank 3 and the liquid storage chamber 4 can be normally mutually discharged.
Optionally, the bottom plate of the pressure supply groove 3 is smoothly designed with the contact surface of the upper pressure roller 2, so that the friction force between the upper pressure roller 2 and the pressure supply groove 3 during rotation is reduced.
It should be noted that, the friction between the upper compression roller 2 and the pressure supply groove 3 is reduced when the upper compression roller rotates, so that the upper compression roller 2 can rotate more stably, and the energy consumption of rotation is reduced.
