Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides an inking device on color box printing machine, including a plurality of ink horn 1 that sets up side by side, the ink horn that sets up side by side is used for storing the ink of different colours respectively, therefore the inking device that provides in this embodiment is only applicable to fluidic ink, is unsuitable for the crocus, and the principle of inking is through the self-priming effect of shower nozzle and the inside ink of extrusion ejection capacity volume and realizes corresponding printing function.

According to the above, in the present embodiment, the ink cartridge 1 is provided with at least two ink outlets 2, for example, three ink outlets 2 are provided, and the plurality of ink outlets 2 are provided to adapt to the height and volume of the ink cartridge 1, so as to prevent that ink cannot be discharged or ink cannot be discharged due to local dead angles or blockage of the ink outlets 2, because all the ink outlets 2 are in the same state for the same ink cartridge 1, each ink cartridge 1 is connected to a self-priming nozzle through an ink guide tube connected to the ink outlet 2, and for the same ink cartridge 1, all the ink outlets 2 are converged together through the ink guide tube to be communicated with the self-priming nozzle.

Ink horn 1 includes the glossy box body 3 of internal surface the top fixed mounting of box body 3 has gallows 4, the gallows 4 bottom is installed free rotation through sealed bearing and is pushed away the china ink board 5, through the gallows 4 that set up with push away china ink board 5 with box body 3 be divided into operation room 7 and store up the china ink room 8, ink outlet 2 sets up on the lateral wall of storing up the china ink room 8.

In the present embodiment, the ink stored in the ink storage space 8 is pushed out through the ink outlet hole 2 by the pressing action of the ink pushing plate 5, enters the ink guide tube, and is delivered to the self-priming nozzle. Since ink is stored, it is necessary to ensure the tightness of the connection between the ink pushing plate 5 and the ink reservoir 8.

In order to achieve the purpose, a guide arc panel 6 installed at the bottom of the box body 3 is arranged below the ink pushing plate 5, the guide arc panel 6 is symmetrical about a vertical plane where the hanging bracket 4 is located, the bottom of the ink pushing plate 5 can be always tightly attached to the guide arc panel 6 by adopting a symmetrical arrangement method, the inner surface of the guide arc panel 6 is smooth, a rubber soft plate 17 is arranged at the position where the bottom of the ink pushing plate 5 is in contact with the guide arc panel 6, the rubber soft plate 17 is arranged to enable connection between the bottom of the ink pushing plate 5 and the guide arc panel 6 to be tighter, pressure loss caused by leakage of ink located between the ink storage chambers 8 can be effectively avoided, and the problem that ink is not smoothly discharged or ink discharge amount is insufficient is avoided.

In the present embodiment, the ink discharging power comes from two aspects, the first is that the self-suction type nozzle sucks the ink in the ink storage chamber 8 due to the pressure difference during the ink discharging process, and the second is that the ink is pushed out by the elastic potential energy in the operation chamber 7. The cooperation of these two ways makes ink can be smoothly extruded, should be comparatively extensive in prior art about the theory of operation of self-priming shower nozzle, does not give unnecessary details to this, and this embodiment will combine specific scheme to explain in detail the pressure variation process in the operation.

Push away the central fixed mounting that china ink board 5 is located one side of operation room 7 has roof 9, and the setting of roof makes the pressure in the operation room 7 can be balanced act on pushing away china ink board 5, connect through elastic expansion frame 10 between roof 9 and the 7 inner walls of operation room, just be in equal fixed mounting in roof 9 both ends has adjusting spring 11, adjusting spring 11 the other end also with 7 inner wall fixed connection of operation room.

In addition, the ink pushing plate 5 is a hollow rhombohedron, isothermal liquid is filled in a rhombohedron cavity of the ink pushing plate 5, the isothermal liquid is liquid or mixed solution with high specific heat capacity, the temperature in the ink storage chamber 8 can be kept stable, and the quality of the ink pushing plate 5 can be reduced by the built-in liquid.

When storing up the china ink room 8 and being in when filling up the ink, push away the china ink board this moment and be located leftmost side, elasticity expansion bracket 10 and adjusting spring 11 all are in compression state this moment, and the ink in storing up the china ink room 8 this moment receives the squeezing action and is in high pressure state, because in order to avoid the ink by too high pressure basis, still be in install pressure relief valve 12 in the ink outlet 2, impurity is filtered on the one hand in the effect of pressure relief valve 12, and on the other hand plays and stops the effect, avoids the high pressure to the influence of ink.

As the ink in the ink storage space 8 is continuously consumed, the ink pushing plate 5 is continuously moved to the right side, and the compression distance is reduced, so that the elastic force of the ink pushing plate 5 is reduced, and the ink discharging capability cannot be provided when the elastic force of the ink pushing plate 5 is consumed, and at this time, the ink storage space 8 needs to be filled with ink.

As is clear from the above, the pressure in the ink tank 8 varies with the loss of ink, and the pressure reducing valve 12 also needs to exert a pressure reducing force in order to avoid such a variation directly acting on the ink discharge process.

Therefore, in the present invention, the pressure relief valve 12 includes a valve body 13, and a primary screen 14, a secondary screen 15, and a barrier film 16 are sequentially disposed inside and outside the valve body 13. The primary screen 14 and the secondary screen 15 both play a role in filtering, the barrier film 16 does not affect the flow and seepage of ink molecules and only plays a role in buffering pressure, the specific structure of the barrier film 16 is a multi-layer mesh-shaped structure, the material of the barrier film can be a non-woven fabric type, and the principle is that the flow rate of fluid is reduced through the multi-layer mesh-shaped structure, the passing time of the fluid is delayed, so that the fluid pressure on the other side is reduced, and the effect of buffering pressure is played.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
