The water blocking plates 12 are trapezoidal block structures.

[0028] The working principle of the above embodiment is as follows: When the device is used, the digital machine body 1 cooperates with the printing roller 2 to realize the basic digital printing function. This technical effect is a mature technology. The highlight of the innovative structure is not described in detail. The digital machine body 1 uses the conveying roller 3 to ensure that the printed cloth is conveyed out of the device. When the device is printing, the electric telescopic rod 6 will retract the washing assembly 9 and the rotating assembly 11 on the collecting groove block 7 to the lowermost side of the digital machine body 1, so as not to affect the normal operation of the digital machine body 1. When the printing roller 2 needs to be cleaned, the electric telescopic rod 6 will drive the washing assembly 9 and the rotating assembly 11 on the collecting groove block 7 to approach the printing roller 2 to prepare for cleaning. During the process of cleaning the printing roller 2, the device is in a stopped state, and cleaning liquid needs to be added into the water storage drawer 5 below the conveying water pump 801 before cleaning, so as to realize the effect of water pumping and discharging of the conveying water pump 801. When the electric telescopic rod 6 drives the structure on the collecting groove block 7 to contact the printing roller 2, the printing roller 2 can be cleaned. During the cleaning process of the printing roller 2, the printing roller 2 needs to be started to rotate, and the rotating direction of the electric cylinder 1102 in the device is opposite to the rotating direction of the printing roller 2. In this way, through the reverse rotating force, the surface of the printing roller 2 can be better washed by the brush cylinder 1103. The water pump 801 delivers the cleaning liquid in the water storage drawer 5 to the conveying vertical pipe 802, and the cleaning liquid is introduced into the inclined scraping shell plate 901 through the connecting hose 903. Then the cleaning liquid passing through the partition hole plate 902 pushes the flow plate 1108 to move upward. During the upward movement of the flow plate 1108, the top block 1107 on the sliding plate 1105 is driven to move upward. During the upward movement of the top block 1107, the rotating connecting block 1110 is driven to rotate around the support block 1111. In this way, the rotating connecting block 1110 drives the fixed frame block 1101 to rotate close to the inclined scraping shell plate 901 through the fixed block 1109. In this way, the movement of the fixed frame block 1101 close to the inclined scraping shell plate 901 makes the brush cylinder 1103 more tightly fit the printing roller 2, thereby ensuring the cleaning effect of the surface of the printing roller 2. Finally, the liquid in the inclined scraping shell plate 901 is discharged through the flow port 904. In this way, the surface of the printing roller 2 can be washed, and the impurities and pigments on the surface of the printing roller 2 can be removed by the rotating brushing effect of the brush cylinder 1103. The removed sewage is introduced into the left water storage drawer 5 through the sewage pipe 10 under the collecting groove block 7, which is convenient for centralized treatment later. After a period of cleaning, the operator needs to manually start the hot air blower 803 to dry the cleaned printing roller 2. When the hot air blower 803 is started, the water pump 801 is closed. In this way, the conveying vertical pipe 802 is filled with warm gas, and the warm gas is discharged through the flow port 904 on the inclined scraping shell plate 901 to dry the surface of the printing roller 2. Since the inclined scraping shell plate 901 conveys the warm gas, the surface of the inclined scraping shell plate 901 will have heat, and the hot air blowing method not only ensures that the printing roller 2 is dried, but also increases the drying efficiency of the printing roller 2. During the conveying process of the gas, since the density of the gas is less than the density of the liquid, the flow plate 1108 cannot be ensured to move upward during the conveying process of the gas. In this way, under the weight of the fixed frame block 1101 and the structure on the fixed frame block 1101, the brush cylinder 1103 on the fixed frame block 1101 moves away from the printing roller 2, thereby better ensuring the drying effect of the surface of the printing roller 2. When the drying is finished, the electric telescopic rod 6 drives the structure on the collecting groove block 7 to retract to the bottom of the digital machine body 1, which does not affect the normal operation effect of the digital machine body 1. After cleaning, the left water storage drawer 5 needs to be removed for centralized treatment of sewage to avoid affecting the use quality of the whole device.

[0029] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are all common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved. In addition, the electrical components appearing in the embodiment are all electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which can play a control role. A person skilled in the art can realize the control of the electrical components through simple programming. The existing disclosed power connection technology also belongs to the common knowledge in the field. Therefore, the specific structural components and working principles will not be described in detail in the embodiment.
