[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides two technical solutions:

[0021] Figure 1-3The first embodiment is shown: an ink saving device capable of precisely controlling ink, comprising a housing 1, a partition plate 2 for dividing the housing 1 into a liquid storage chamber 5 and an adjusting chamber 3, a stirring assembly 66 for rotating inside the liquid storage chamber 5, an adjusting assembly 4 for controlling the ink output amount inside the adjusting chamber 3, the adjusting assembly 4 comprising a threaded rod 41, a limit plate 42 fixedly disposed at the end of the threaded rod 41, a piston 44 fixedly disposed on the limit plate 42 via a return spring 43, a bearing 45 threadedly sleeved on the threaded rod 41 outside the adjusting chamber 3, a support frame fixedly disposed outside the bearing 45, a pulley A46 fixedly disposed at the bottom of the bearing 45, the pulley A46 being transmission-connected to the stirring assembly 6, the stirring assembly 6 comprising a motor 61, a stirring shaft 62 fixedly disposed at the output end of the motor 61, a plurality of stirring plates 63 fixedly disposed on the stirring shaft 62, A stirring plate 63 on the stirring shaft 62 stirs the ink to prevent the ink from condensing into blocks and causing blockage. A connector 64 is fixedly provided at the end of the stirring shaft 62. A rotating shaft 66 with a connecting groove 65 is rotatably provided on the top of the regulating chamber 3 on the connecting head 64. A pulley B67 is fixedly provided on the rotating shaft 66. The pulley A46 is connected to the pulley B67 for transmission. Telescopic cylinders 7 are fixedly provided on both sides of the motor 61. A connecting plate is fixedly provided at the end of the telescopic cylinder 7. The connecting plate is fixedly connected to the bottom of the motor 61. A one-way valve 13 is fixedly provided at the bottom of the partition 2. An ink outlet valve 14 is fixedly provided on the top of the regulating chamber 3. An ink plate with a nozzle is fixedly connected to the ink outlet valve 14 through an ink supply pipe. The valve stem of the one-way valve 13 is connected to the valve stem of the ink outlet valve 14 through a belt and a pulley transmission. When one of the one-way valve 13 and the ink outlet valve 14 is connected, the other is closed.

[0022] Compared with the existing device, the device drives the stirring shaft 62 to rotate through the motor 61 to prevent the ink from agglomerating. At the same time, the connecting block at the end of the stirring shaft 62 drives the rotating shaft 66 to rotate, and the pulley B67 drives the threaded rod 41 to move, thereby controlling the internal capacity of the regulating chamber 3, and adjusting the air pressure delivered to the regulating chamber 3 through the cross three-way valve, thereby controlling the flow rate of the ink, thereby achieving precise ink control and reducing ink waste.

[0023] Figure 1-2A second embodiment is shown, which mainly differs from the first embodiment in that an air pump 8 is fixedly provided on the top of the box body 1, an electronic cross valve 9 is fixedly provided on the output end of the air pump 8, an air supply pipe 10 fixedly connected to the telescopic cylinder 7 is provided on the electronic cross valve 9, a boosting pipe A11 penetrating through the box body 1 to the top of the ink storage chamber is fixedly provided on one side of the electronic cross valve 9, a boosting pipe B12 arranged on the limit plate 42 is provided on the other side of the electronic cross valve 9, an ink inlet pipe with a valve is fixedly provided on the box body 1 at one side of the ink storage chamber, and observation windows 15 with scales are opened on the box body 1 at the regulating chamber 3 and the ink storage chamber. The observation window 15 allows users to observe the capacity of ink in the regulating chamber 3 and the capacity of the liquid storage chamber 5, thereby improving the accuracy of ink control.

[0024] The capacity and air pressure of the ink in the regulating chamber 3 are rationally distributed through the connector 64 at the end of the stirring shaft 62 and the electronic cross valve 9 on the air pump 8 at the top of the box 1, thereby improving the utilization rate of its resources and reducing its printing cost.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0026] During use, the telescopic cylinder 7 drives the motor 61 to move so that the connector 64 at the end of the stirring shaft 62 is sleeved in the connecting groove 65, and then the motor 61 is started to drive the rotating shaft 66 to rotate, and the pulley B67 at its end drives the pulley A46 on the bearing 45 to rotate synchronously, and at the same time, the stirring plate 63 on the stirring shaft 62 is used to stir the ink, so that the threaded rod 41 drives the limit plate 42 to move upward. When it moves to a suitable position, the air pressure generated by the air pump 8 is transmitted to the telescopic cylinder 7 through the air supply pipe 10, thereby driving the motor 61 to move, so that the connector 64 at the end of the stirring shaft 62 is separated from the connecting sleeve, and then rotated. The valve of the one-way valve 13 on the front side of the box 1 drives the valve of the ink outlet valve 14 to rotate synchronously through a belt, so that the one-way valve 13 is opened and the ink outlet valve 14 is closed, and then the air pressure generated by the air pump 8 is transmitted to the ink storage chamber through the boosting pipe A11, so that the ink inside it flows into the regulating chamber 3 through the one-way valve 13. When the ink capacity reaches a suitable position, the valve of the one-way valve 13 is rotated to close the one-way valve 13 and open the ink outlet valve 14. Then, pressure is transmitted to the inside of the regulating chamber 3 through the boosting pipe B12, so that the pressure moves through the piston 44, thereby causing the ink to be sprayed out through the nozzle on the ink plate. After the ink is sprayed, the piston 44 returns to its initial position under the action of the reset spring 43.
