For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] A digital printing machine print nozzle temperature control device, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including trolley bottom plate 1, the top of the trolley bottom plate 1 is fixedly connected with water tank 2, the top of the water tank 2 is inserted with liquid level sensor 3, one side of the water tank 2 is threadedly connected with sound alarm 4, the top of the trolley bottom plate 1 is threadedly connected with control mechanism 5, and the trolley bottom plate 1 is uniformly provided with notches, the inner wall bottom of the notch is threadedly connected with spray head 6, the trolley bottom plate 1 is internally provided with cooling mechanism 7, and the spray head 6 is internally provided with temperature sensor, and the model of the liquid level sensor 3 is EE-SPX613, the model of the sound alarm 4 is AD16-22SM, and the model of the temperature sensor is PT100.

[0029] When the digital printing machine starts to work, the temperature sensor monitors the temperature of the nozzle 6 in real time. When the temperature is higher than the preset value, the cooling liquid in the water tank 2 enters the cooling mechanism 7 with the help of the control mechanism 5, circulates in the cooling mechanism 7, and takes away the heat of the trolley bottom plate 1. The liquid level sensor 3 monitors the liquid level in the water tank 2. When it is lower than the minimum liquid level threshold, it transmits a signal to the control mechanism 5 and makes the sound alarm 4 alarm. Thus, the temperature of the trolley bottom plate 1 is changed to indirectly affect the temperature of the nozzle 6 when printing, so that the nozzle 6 can print at the most suitable temperature interval. Moreover, the cooling liquid can be added by the operator to prevent the nozzle 6 from overheating due to insufficient cooling liquid.

[0030] In order to control the temperature of the nozzle 6, as shown in Figure 2 and Figure 3 , the control mechanism 5 includes a fixed plate 501, a micro water pump 502, a silica gel heating sheet 503, a protective box 504, a microcontroller 505, and a top cover 506. The fixed plate 501 is fixedly connected to the top of the trolley bottom plate 1. The micro water pump 502 is threadedly connected to the top of the fixed plate 501. The silica gel heating sheet 503 is bonded to one side of the nozzle 6. The protective box 504 is fixedly connected to the bottom of the trolley bottom plate 1. The microcontroller 505 is fixedly connected to the inner wall of the protective box 504. The top cover 506 is slidingly connected to the bottom of the protective box 504. The model of the micro water pump 502 is BSP27250S. The model of the silica gel heating sheet 503 is SRP-220-100. The model of the microcontroller 505 is STM32F103.

[0031] Before printing, the micro water pump 502, the cooling mechanism 7, and the water tank 2 are connected through the pipeline. During printing, the temperature sensor monitors the temperature of the nozzle 6 in real time and transmits the temperature information to the microcontroller 505 through the wire. After receiving the signal, the microcontroller 505 compares it with the preset suitable temperature interval of the nozzle 6. When the temperature is higher than the upper limit temperature, the microcontroller 505 sends a start signal to the micro water pump 502, so that the cooling liquid in the water tank 2 enters the cooling mechanism 7 and flows in the cooling mechanism 7. Then the cooling liquid enters the water tank 2 again to realize circulation. When the weather is cold and the temperature is lower than the preset temperature, the microcontroller 505 sends a start signal to the silica gel heating sheet 503 to transfer heat to the nozzle 6. Thus, the temperature of the nozzle 6 is accurately controlled, so that the nozzle 6 can maintain the best working temperature, which helps to improve the printing precision and quality, reduces the uneven ink caused by temperature, and prolongs the service life of the nozzle 6.

[0032] In order to uniformly cool all the nozzles 6, as shown in Figure 4 and Figure 5As shown, the cooling mechanism 7 comprises a plug 701, a drainage joint 702, a water inlet joint 703, a vertical pipeline 704 and a horizontal pipeline 705, the drainage joint 702 is opened on the top of the trolley bottom plate 1, the water inlet joint 703 is opened on the top of the trolley bottom plate 1, the vertical pipeline 704 is embedded in the inside of the trolley bottom plate 1, the horizontal pipeline 705 is embedded in the bottom of the trolley bottom plate 1, and the vertical pipeline 704 and the horizontal pipeline 705 are uniformly distributed, the plug 701 is inserted into each pipeline interface, and the water inlet joint 703 is connected to the micro water pump 502 through the pipeline, and the drainage joint 702 is connected to the water tank 2 through the pipeline.

[0033] When the condensed liquid enters the vertical pipeline 704 and the horizontal pipeline 705 through the water inlet joint 703 and flows in the inside, and finally flows into the inside of the water tank 2 through the drainage joint 702, the trolley bottom plate 1 is rapidly cooled, and the temperature of each nozzle 6 is indirectly adjusted.

[0034] Working principle: when the digital printing machine starts to work, the temperature sensor monitors the temperature of the nozzle 6 in real time, when the temperature is higher than the preset value, the cooling liquid in the water tank 2 enters the inside of the cooling mechanism 7 with the help of the control mechanism 5, circulates in the inside of the cooling mechanism 7, and takes away the heat of the trolley bottom plate 1, and when the liquid level in the water tank 2 is lower than the minimum liquid level threshold, a signal is transmitted to the control mechanism 5, and the sound alarm 4 is alarmed, before printing, the micro water pump 502, the cooling mechanism 7 and the water tank 2 are connected through the pipeline, when printing, the temperature sensor monitors the temperature of the nozzle 6 in real time, and transmits the temperature information to the microcontroller 505 through the wire, after receiving the signal, the microcontroller 505 compares with the preset suitable temperature interval of the nozzle 6, when the temperature is higher than the upper limit temperature, the microcontroller 505 sends a start signal to the micro water pump 502, so that the cooling liquid in the water tank 2 enters the inside of the cooling mechanism 7, and flows in the inside of the cooling mechanism 7, and then the cooling liquid enters the inside of the water tank 2 again to realize circulation, when the weather is cold and the temperature is lower than the preset temperature, the microcontroller 505 sends a start signal to the silica gel heating sheet 503, and transmits heat to the nozzle 6, when the condensed liquid enters the vertical pipeline 704 and the horizontal pipeline 705 through the water inlet joint 703, and flows in the inside, and finally flows into the inside of the water tank 2 through the drainage joint 702.

[0035] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
