[0002] A belt-type digital textile printing machine is a device for digital printing on textiles. To ensure adhesion between the textile and the belt, a layer of belt adhesive is usually coated on the belt. During the actual printing process, this adhesive coating easily absorbs fabric lint, fiber debris, and spilled ink. These impurities affect print quality, therefore, a cleaning water tank is needed to clean the belt. Traditional cleaning water tanks have uncontrolled spraying actions and timing, leading to significant water consumption and wastewater discharge. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and thoroughly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] The technical features involved in the various embodiments of this application described below do not conflict with each other and can be combined with each other.

[0037] Furthermore, although the functional modules are divided in the device schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps may be performed in a different order than those shown in the device.

[0038] The terms "first," "second," and "third" used in this article do not limit the data, devices, or execution order; they are merely used to distinguish identical or similar items with essentially the same function and purpose.

[0039] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] A belt-type digital textile printing machine is a device for digital printing on textiles. It utilizes advanced inkjet technology to directly print images onto the surface of the textile, offering advantages such as high precision, high speed, and environmental friendliness. During operation, the belt smoothly transports the textile between the inkjet heads, ensuring print quality.

[0041] To ensure adhesion between the textile and the printing belt, a layer of adhesive is typically applied to the belt. This adhesive coating increases the coefficient of friction between the belt and the textile, preventing slippage during printing. However, in actual printing, the adhesive coating easily attracts fabric lint, fiber debris, and spilled ink. These impurities can affect the flatness and adhesion of the belt, thus impacting print quality. Therefore, the printing belt needs to be cleaned regularly during the printing process.

[0042] In existing technologies, belt-type digital textile printing machines typically employ a cleaning tank with brush rollers and spray pipes to rinse the guide belt. During printing, the spray pipes continuously spray water onto the guide belt, assisting the brush rollers in cleaning impurities. However, existing cleaning tanks have shortcomings in terms of spraying action and timing; the spraying process is uncontrolled, often resulting in significant water waste and wastewater generation. Furthermore, excessive water consumption increases the cost burden on customers during equipment operation.

[0043] To address these issues, this invention proposes a method for precisely controlling the water spraying timing of a spray pipe. Specifically, the start time of the guide belt's stepping movement is obtained, and the spray pipe is controlled to spray water onto the guide belt at the first moment before the stepping movement begins; when the stepping movement is completed, the spray pipe is controlled to stop spraying water. This improves the cleaning effect of the guide belt, reduces water consumption and wastewater discharge, and alleviates the customer's operating costs.

[0044] In some embodiments, such as Figure 1 As shown, the conveyor belt cleaning system includes a controller 100 and a spray pipe 200. The spray pipe 200 is positioned at a first distance from the conveyor belt, and the water spray direction of the spray pipe 200 is towards the conveyor belt cleaning surface. The spray pipe 200 is electrically connected to the controller 100, and the controller 100 is used to control the spray pipe 200 to implement the conveyor belt cleaning method provided in this application embodiment.

[0045] In some embodiments, such as Figure 2As shown, the controller 100 includes at least one processor 10 and a memory 20 connected in communication. Figure 2 (Taking a bus connection and a single processor as an example). Those skilled in the art will understand that... Figure 2 The structure shown is for illustrative purposes only and does not limit the structure of the controller described above. The controller may also include components that are more... Figure 2 The more or fewer components shown, or having the same Figure 2 Different configurations are shown. For example, controller 100 may include an interface for communicating with other control systems, and may also include devices such as cameras for recognizing the movement state of the guide belt, and devices such as touch screens and physical buttons for setting the spray nozzles to spray water.

[0046] The memory 20 is used to store software programs, computer-executable program instructions, etc. The memory 20 may include a program storage area and a data storage area, wherein the program storage area may store the operating system and application programs required for at least one function; the data storage area may store data created based on the use of the cleaning system, etc.

[0047] The memory 20 can be a read-only memory (ROM), or other types of static storage devices that can store static information and instructions, or random access memory (RAM), or other types of dynamic storage devices that can store information and instructions, or electrically erasable programmable read-only memory (EEPROM), and the specific type is not limited here.

[0048] For example, the aforementioned memory 20 can be Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM). This memory 20 can exist independently but is connected to the processor 10. Optionally, the memory 20 can also be integrated with the processor 10, for example, integrated within one or more chips.

[0049] In some embodiments, the memory 20 may optionally include memory remotely located relative to the processor 10, and this remote memory may be connected to the conveyor belt cleaning system via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0050] The processor 10 connects various parts of the entire conveyor belt cleaning system using various interfaces and lines. By running or executing software programs stored in the memory 20 and calling data stored in the memory 20, it performs various functions of the conveyor belt cleaning system and processes data, such as implementing the conveyor belt cleaning method described in any embodiment of this application.

[0051] The processor 10 can be a field programmable gate array (FPGA), a digital signal processor (DSP), a central processing unit (CPU), or the like.

[0052] Processor 10 can be a single-core processor or a multi-core processor. For example, processor 10 can be composed of multiple FPGAs or multiple DSPs. Furthermore, processor 10 can refer to one or more devices, circuits, and / or processing cores for processing data (e.g., computer program instructions). Processor 10 can be a standalone semiconductor chip or integrated with other circuits into a single semiconductor chip. For example, it can form a system-on-a-chip with other circuits (such as encoding / decoding circuits, hardware acceleration circuits, or various bus and interface circuits).

[0053] (System-on-a-chip, SoC), or it can be integrated into the ASIC as a built-in processor as an application-specific integrated circuit (ASIC). The ASIC with integrated processor can be packaged separately or together with other circuits.

[0054] As will be understood by those skilled in the art, the above is merely an example of the hardware structure of the conveyor belt cleaning system. In practical applications, more components can be added according to actual functional needs. Of course, one or more components can also be omitted according to functional needs.

[0055] The following describes the conveyor belt cleaning method according to an embodiment of this application. This method can be executed by the conveyor belt cleaning system described above. Please refer to [link / reference]. Figure 3 The method S100 includes:

[0056] S101: Obtain the start time of the guide belt stepping motion.

[0057] During the printing process, the print head prints along the width of the fabric, printing an image of one unit distance at a time. The time taken to print one unit distance is one printing cycle. At the end of one printing cycle, the guide belt begins to step forward, moving the fabric forward one unit distance to begin the next printing cycle.

[0058] In some embodiments, the start time of the guide belt stepping motion can be determined based on the printing cycle. The controller of the guide belt cleaning system can identify and obtain the printing cycle by communicating with the internal control system of the digital printing machine, or it can identify the guide belt motion of the digital printing machine to obtain the printing cycle through other means such as a camera. The following describes an embodiment in which the controller of the guide belt cleaning system communicates with the internal control system of the digital printing machine to identify and obtain the printing cycle, specifically including:

[0059] Communication connection: Establish a communication connection between the controller of the guide belt cleaning system and the internal control system of the digital printing machine. This can be achieved through wired or wireless means, such as serial communication, Ethernet communication, Bluetooth communication, etc.

[0060] Acquiring Printing Status Data: After communicating with the internal control system of the digital printing machine, the controller can acquire the printing status data of the printing machine in real time. This data includes the working status of the print head, the position information of the fabric, and other relevant information.

[0061] Determining the Print Cycle: The controller parses the received print status data to determine the current print cycle. Typically, the print cycle refers to the time required for the print head to complete one unit of image. The controller can determine the print cycle by calculating the time it takes for the print head to print one unit of image distance or by using relevant parameters provided by the printing machine's internal system.

[0062] Understandably, once the printing cycle is obtained, the start time of each guide belt step movement can be acquired. Through the above steps, the controller of the guide belt cleaning system can effectively identify and obtain the printing cycle of the digital printing machine, achieving precise control over the guide belt cleaning process.

[0063] S102: At the first moment before the start time of the stepping motion, control the spray pipe to spray water so that the spray pipe sprays water onto the guide belt.

[0064] Because there is a first distance interval between the spray pipe and the guide belt, in order to ensure that the guide belt can be effectively cleaned during the stepping motion, the spray pipe needs to be activated to spray water onto the guide belt at the very first moment before the stepping motion begins. This ensures that the sprayed water has reached the surface of the guide belt when the stepping motion starts. The first moment can be determined by the first distance interval and the spraying speed of the spray pipe.

[0065] When the first moment arrives, the controller sends a command to the spray pipe to start the water spraying. Through the above design, the belt cleaning method can precisely control the water spraying time of the spray pipe, ensuring that the belt is effectively cleaned during each step movement, making the relative movement of the spray pipe and the belt more coordinated, thereby improving the cleaning effect of the belt.

[0066] In other embodiments, the spray pipe is controlled to spray water so that, before spraying water onto the guide belt, the position of the spray pipe can be adjusted so that the spray direction of the spray pipe forms a first angle with the guide belt. For example, the spray direction is 15°-45° with the forward direction of the guide belt.

[0067] Understandably, adjusting the position of the spray pipe ensures that the water is sprayed onto the guide belt at the appropriate position and angle, resulting in a more concentrated water flow and more even coverage. Furthermore, the washed-off dirt will fall off in the direction the guide belt is moving, thus improving the cleaning effect. This increases the cleanliness of the guide belt surface and reduces potential cross-contamination during printing. It's somewhat similar to sanitation workers using a spray gun to spray water onto the road surface for cleaning.

[0068] S103: When the guide belt stepping motion is completed, control the spray pipe to stop spraying water.

[0069] To control the spray pipe to stop spraying water when the guide belt's stepping motion is complete, the end time of the stepping motion needs to be known. In some embodiments, the end time of the stepping motion can be obtained based on the start time and period of the stepping motion. The period of the stepping motion is the time required for the guide belt to complete one stepping motion, which is calculated using the stepping motion length, acceleration, and deceleration provided by our printing software. Adding the start time of the guide belt's stepping motion to the period of the stepping motion yields the end time of the guide belt's stepping motion. When the guide belt's stepping motion is complete, the spray pipe is controlled to stop spraying water.

[0070] In some embodiments, users can set the delayed water spraying time and duration of the spray pipes through the controller interface of the conveyor belt cleaning system. The interface can be a touchscreen, a physical button, or a computer program. For example, the system can set the spray pipes to stop spraying water at a second moment after the end of the conveyor belt's stepping motion; this second moment is the end time plus the user-set delay duration. This embodiment allows users greater flexibility in controlling the spraying process, delaying the water spraying action after the conveyor belt's stepping motion stops. This ensures that the water spraying continues for a period of time after the conveyor belt's stepping motion stops, guaranteeing 100% cleaning of the area to be cleaned and increasing the cleaning effect. The delay time can be adjusted according to actual needs and cleaning effect to achieve the best cleaning result.

[0071] By implementing the above-mentioned belt cleaning method S100, the spraying time of the spray pipe can be precisely controlled, making the relative movement of the spray pipe and the belt more coordinated, thereby improving the cleaning effect of the belt, reducing water waste, and lowering customer operating costs.

[0072] In some other embodiments, before step S101 of the above method S100, the method further includes determining whether the digital printing machine is performing a printing job. If the digital printing machine is performing a printing job, then the steps of the above method S101-S103 are performed.

[0073] It is understandable that the specific implementation for determining whether a digital printing machine is performing a printing job may vary depending on different system designs and configurations. In some embodiments, the controller of the conveyor belt cleaning system can communicate with the central processing unit (CPU) or other control unit of the digital printing machine to obtain the machine's operating status. This communication can be conducted through various interfaces, such as serial interfaces, parallel interfaces, and wireless interfaces. After obtaining the digital printing machine's operating status information, the controller will determine whether the printing machine is performing a printing job. Specifically, the controller will check certain status flags or parameters, such as "print job status" and "whether the print queue is empty," and can determine whether the digital printing machine is performing a printing job based on these flags or parameters.

[0074] In some other embodiments, before step S101 of the above method S100, the method further includes determining whether the digital printing machine is performing a printing operation; if the digital printing machine is not performing a printing operation, determining whether the guide belt is moving; if the guide belt is moving, controlling the spray pipe to spray water; and when the guide belt stops moving, controlling the spray pipe to stop spraying water.

[0075] Understandably, even when the digital printing machine is not performing a printing operation, the guide belt may move due to other machine movements or operations. In such cases, traditional cleaning methods may neglect cleaning the guide belt, leaving any dirt on it unremoved and affecting its operating efficiency and lifespan.

[0076] In this embodiment, if the controller determines that the digital printing machine is not performing a printing operation, it will further determine whether the guide belt is moving. This determination is usually achieved by reading the position or speed information of the guide belt. If the controller detects that the guide belt is moving, it will activate the spray pipes to spray water to clean the guide belt. When the controller detects that the guide belt has stopped moving, it will control the spray pipes to stop spraying water, thereby avoiding unnecessary water consumption.

[0077] By implementing this embodiment, it is ensured that the guide belt can still be properly cleaned even when the digital printing machine is not performing printing operations, while also avoiding excessive consumption of water resources.

[0078] The conveyor belt cleaning method provided in this application will be described below with a specific embodiment. In specific applications, when setting the conveyor belt cleaning system to spray water in advance and with a delayed spray time, the typical settings are 0.05S-0.15S in advance and 0.3S-1S with a delayed spray time. Figure 4 As shown, preferably, the first time is set to 0.1S, that is, the spray pipe starts spraying water 0.1S before the guide belt starts stepping motion; the second time is set to 0.5S, that is, the spray pipe sprays water 0.5S after the guide belt finishes stepping motion.

[0079] First, turn on the power to the digital printing machine and the conveyor belt cleaning system to enable them to supply power and enter standby mode. The method for determining whether the digital printing machine has a printing job is described in the other embodiment above and will not be repeated here.

[0080] When a digital printing machine has a printing job in progress, the conveyor belt cleaning system performs the following steps:

[0081] Obtain the printing cycle, and use the printing cycle to obtain the start time of the guide belt stepping movement. Set the spray pipe to start spraying water 0.1 seconds before the start of the guide belt stepping movement.

[0082] Wait 0.1 seconds before the guide belt steps forward. When 0.1 seconds before the guide belt steps forward, control the spray pipes to start spraying water. The guide belt of the digital printing machine begins to move according to the set step distance and printing cycle, completing one step distance of printing;

[0083] After the conveyor belt completes its stepping motion, a 0.5-second delay is set to turn off the water spray, during which the spray pipe continues to spray water. After 0.5 seconds, the spray pipe is turned off, completing the cleaning of one stepping distance of the conveyor belt.

[0084] Even when the digital printing machine is not performing a printing job, the guide belt may still move due to other machine movements or operations. In this case, the guide belt also needs to be cleaned. Perform the following steps:

[0085] The system detects whether the conveyor belt is moving. If movement is detected, the spray pipes are activated to spray water and clean the belt. When the conveyor belt stops moving, the spray pipes are deactivated to stop spraying water.

[0086] In the above embodiments, by precisely controlling the timing of water spraying, the spraying time and action are optimized, thereby achieving energy saving and emission reduction. For example, if using a traditional cleaning method, in a digital printing machine printing a 1.8-meter wide pattern, the printing time is 5 minutes, the water pressure for cleaning spraying is 0.22-0.29 MPa, and the water flow rate is 64.08 L, which translates to a water flow rate of 768.96 L / h. If printing operations last 24 hours a day, the total water consumption is approximately 18.45 m³. 3 By implementing the belt cleaning method of this embodiment, in a digital printing machine printing a pattern 1.8 meters wide, the printing time is 5 minutes. The water pressure of the cleaning spray is 0.22-0.29 MPa, and the water flow rate is 22.78 L, which translates to a water flow rate of 273.36 L / h. Over a 24-hour printing operation, the total water consumption is approximately 6.56 m³. 3 It is evident that, under the same conditions and operating state, the conveyor belt cleaning method provided in this application saves 64.44% of water.

[0087] In summary, the embodiments of this application provide a conveyor belt cleaning method, specifically including: obtaining the start time of the conveyor belt's stepping movement; controlling the spray pipe to spray water onto the conveyor belt at the first moment before the stepping movement begins; and controlling the spray pipe to stop spraying water when the stepping movement is completed. This method achieves precise control of the water spraying time, improves the conveyor belt cleaning effect, reduces water consumption and wastewater discharge, and contributes to energy conservation, emission reduction, and lower customer operating costs.
