DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0032] like Figure 1-3As shown, the present invention is a digital printing device applied to the lock industry, including a printing device 1, a device frame 2 and a control computer 3. The printing device 1 includes a printing module 11 and a printing base plate 12. The printing base plate 12 is installed on the device frame 1. The printing module 11 is installed on the rear side of the printing base plate 12 and connected to the device frame 2. The control computer 3 is installed on one side of the device frame 2. The printing module 11 includes a module bracket 111, a nozzle assembly 112, a detection device 113 and a curing device 114. The nozzle assembly 112, the detection device 113 and the curing device 114 are installed on the module bracket 111, and the module bracket 111 is installed on the device frame 2.

[0033] By adopting the above technical solution and the flexible configuration of the printing module 11, the device can be well adapted to the lock industry and other occasions requiring printing of slender, non-standard shaped objects, so that the device can maintain efficient printing capabilities when facing different sizes, shapes and materials. The stable structure of the device frame 2 and the printing base plate 12 provides solid support for the printing module 11, ensuring that the entire printing process can proceed smoothly.

[0034] The printing module 11 also includes a moving module 115. The module bracket 111 carries the nozzle assembly 112, the detection device 113 and the curing device 114 to move on the moving module 115. The movement direction of the moving module 115 is X-axis reciprocating motion. The moving module 115 is installed on the equipment frame 2.

[0035] By adopting the above technical solution, the addition of the mobile module 115 enables the printing module 11 to move freely along the X-axis direction, and the equipment can adapt to a wider range of printing needs, including locks of different lengths or other slender products. It can also print multiple sections or complex patterns on a single product without changing the equipment or adjusting the material position. The precise control of the mobile module 115 ensures the stable movement of the nozzle assembly 112 in the X-axis direction, reduces the printing errors caused by mechanical vibration or improper human operation, and combines with the real-time monitoring of the detection device 113 to further adjust and optimize the printing parameters to achieve higher printing accuracy.

[0036] The printing module 11 further includes a motor lifting module 116 , which is mounted on the module bracket 111 , and the nozzle assembly 112 is mounted on the motor lifting module 116 for vertical movement.

[0037] By adopting the above technical solution, the precise control of the motor lifting module 116 ensures the stable lifting of the nozzle assembly 112 in the vertical direction, so that the nozzle assembly 112 can not only move in the horizontal direction (X axis), but also be precisely adjusted in the vertical direction (Z axis). This multi-dimensional movement capability greatly expands the printing range and flexibility of the device, and can cope with more complex and diverse printing needs.

[0038] The nozzle assembly 112 includes a secondary ink cartridge 1121, a nozzle 1122 and a nozzle fixing plate 1123. The nozzle fixing plate 1123 is installed on the motor lifting module 116. The nozzle 1122 is fixed on the nozzle fixing plate 1123 for operation. The secondary ink cartridge 1121 is installed on the nozzle fixing plate 1123 and connected to the nozzle 1122.

[0039] By adopting the above technical solution, the introduction of the secondary ink cartridge 1121 provides a stable and continuous ink supply for the nozzle 1122 to prevent printing interruptions and quality problems caused by insufficient or unstable ink supply. The fixed nozzle fixing plate 1123 helps to reduce the vibration and displacement of the nozzle during high-speed printing.

[0040] The detection device 113 is specifically a safety grating, which is installed on the nozzle fixing plate 1123 and the safety grating is installed on the opposite side of the nozzle 1122; the curing device 114 is specifically a curing lamp, which is installed on the side of the nozzle fixing plate 1123 on the module bracket 111.

[0041] By adopting the above technical solution, the safety grating, as a non-contact safety protection device, can monitor the dynamics of people or objects in the area around the nozzle 1122 in real time. Once an object or person enters the preset dangerous area, the safety grating will immediately send a signal to stop the equipment or take other safety measures, thereby effectively preventing accidents and improving the safety of the workplace. The curing lamp, as a specific implementation of the curing equipment 114, is installed on the side of the nozzle fixing plate 1123, which can ensure that after the nozzle completes printing, the printing area is immediately cured efficiently and evenly, shortening the curing time, improving production efficiency, and improving the curing effect, making the printed pattern more firm and durable.

[0042] The mobile module 115 includes a mobile track 1151 and a driving motor 1152 . The driving motor 1152 is installed on the module bracket 111 . The module bracket 111 is set on the mobile track 1151 and is controlled to move by the driving motor 1152 . The bottom of the mobile track 1151 is fixedly installed on the equipment frame 2 .

[0043] By adopting the above technical solution, the module bracket 111 is precisely controlled on the movable rail 1151 by driving the motor 1152, so as to realize precise positioning and movement of the components or tools installed on the module bracket. Since the module bracket 111 can move freely along the movable rail 1151 and its position can be adjusted as needed, the flexibility and adaptability of the system are increased. The bottom of the movable rail 1151 is fixedly installed on the equipment frame 2, which provides a stable support foundation and ensures the stability of the mobile module during operation.

[0044] The printing base plate 12 includes a printing plate 121, a folding plate 122 and a pressing rod 123. The printing plate 121 is installed on the equipment frame 2. The folding plate 122 is connected to the side of the printing plate 121. The pressing rod 123 is installed on the printing plate 121 and the folding plate 122 to fix the material to be printed.

[0045] By adopting the above technical solution, the printing plate 121 serves as the direct carrier of the printed pattern, and its stable installation on the equipment frame 2 ensures the position accuracy during the printing process. The design of the pressing rod 123 effectively fixes the material to be printed and prevents the material from moving or deforming during the printing process, thereby improving the accuracy and clarity of the printed pattern. The moderate pressure of the pressing rod 123 can ensure that the material will not be subjected to excessive mechanical stress during the printing process, thereby protecting the integrity and quality of the material.

[0046] It also includes a negative pressure fan 4 and a water cooler 5, which are installed on both sides of the equipment frame 2, the negative pressure fan 4 and the water cooler 5 are connected to the inside of the equipment frame 2, and the negative pressure fan 4 is connected to the printed board 121.

[0047] By adopting the above technical solution, the water cooler 5 uses a circulating water cooling system to promptly remove the heat generated inside the equipment, effectively reducing the operating temperature of the equipment. This is especially important for equipment such as printing presses that need to run for a long time and are prone to generate heat, because high temperature may cause problems such as equipment performance degradation and ink deterioration. The negative pressure fan 4 is connected to the printing plate 121, which can form local airflow control during the printing process, helping to ensure the stability of the material while maintaining the clarity and edge sharpness of the printed pattern.

[0048] A plurality of suction holes 1211 are provided on the printing plate 121 , and the suction holes 1211 are used to connect to the negative pressure fan 4 to absorb and fix the material on the printing plate 121 through the negative pressure generated.

[0049] By adopting the above-mentioned technical solution, the suction hole 1211 is combined with the negative pressure fan 4, and the material is tightly adsorbed on the printing plate 121 through the action of negative pressure. This non-contact fixing method avoids the indentation or damage that may be caused by traditional clamps, while ensuring the stability and accuracy of the material during the printing process. Since negative pressure adsorption does not depend on the physical properties of the material (such as shape, hardness, etc.), it can adapt to the printing of many different types of materials, thereby enhancing the versatility and flexibility of the equipment.

[0050] A working method of a digital printing device applied to the lock industry, specifically comprising the following steps:

[0051] Step 1: First, turn on the power switches of the control computer 3 and the printing device to ensure that all systems are in standby mode. Through the interface of the control computer 3, accurately adjust the motor lifting module 116 so that the nozzle 1122 reaches the optimal printing height suitable for the current material thickness;

[0052] Step 2: Place the prepared lock material steadily on the printing plate 121, pay attention to alignment and positioning, ensure the accuracy of the printing position, adjust the pressing rods 123 on both sides to make them fit closely to the edge of the material, ensure that the material will not move or deform during the printing process, start the negative pressure fan 4 through the control computer 3, and the airflow generated by the negative pressure fan passes through the suction holes 1211 on the printing plate 121, firmly adsorbing the material on the printing plate, further enhancing the fixing effect;

[0053] Step 3: Input or select the preset printing pattern, color, speed and other parameters on the control computer 3, and confirm them. Through PLC programming control, the drive motor 1152 starts working, driving the entire printing module 11 to perform precise reciprocating motion along the X-axis direction. During the movement, the nozzle 1122 absorbs ink from the secondary ink cartridge 1121 according to the preset pattern and color and prints it evenly on the material. The detection device 113 monitors the printing area in real time to ensure that no foreign matter enters during the printing process to ensure safe operation. If there is a foreign matter above the product and it is sensed by the shooting detection device 113, it will stop immediately, which has the effect of emergency stop. After the printing is completed, the curing device 114 immediately solidifies the ink to ensure the firmness and durability of the printed pattern;

[0054] Step 4: When the printing module 11 completes a complete printing and curing cycle, the drive motor 1152 will control it to return to the initial position, and the control computer 3 will issue a command to automatically adjust the pressure rod 123 to release the pressure on the material. The operator can safely take out the printed material and repeat the above steps to prepare the next batch of materials for printing.
