[0042] like Figure 1 to Figure 6 As shown, a belt UV inkjet coding device of a preferred embodiment of the utility model comprises: a frame 1; a belt clamping module 2, the belt clamping module 2 comprises: a mounting member 21, a first hanging belt assembly 22, a second hanging belt assembly 23, and a guide rail 24; the mounting member 21 extends along a first direction, the mounting member 21 is fixedly connected to the frame 1, the guide rail 24 extends along the first direction and is fixedly connected to the mounting member 21, the first hanging belt assembly and the second hanging belt assembly are slidably connected and can be relatively locked to the guide rail 24, and the belt 5 to be printed is wound around the outer periphery of the first hanging belt assembly 22 and the second hanging belt assembly 23; a UV printing module 3, the UV printing module 3 is installed on the frame 1, and can move in the first direction and the second direction for printing the belt 5 to be printed; a coding control cabinet 4, the coding control cabinet 4 and the frame 1 are spaced apart along the first direction, and the UV printing module 3 is electrically connected to the coding control cabinet 4; wherein the first direction and the second direction are perpendicular to each other.

[0043] (1) Significantly improved cost-effectiveness: Reduced screen preparation costs: Traditional silk screen printing requires the production of specific screens for each pattern, which is not only time-consuming but also costly. Inkjet printing technology, especially UV inkjet printing, does not require the production of physical screens, which greatly saves the initial preparation costs. Reduced labor costs: The high degree of automation of inkjet printing technology reduces the need for manual replacement of screens, thereby reducing dependence on skilled workers and saving labor costs. Simplified equipment replacement process: Inkjet printing equipment is generally more flexible and can be easily adjusted to meet the printing requirements of different belts 5 and patterns to be printed, simplifying the complex process of equipment replacement during the printing process. (2) Enhanced adaptability and flexibility: Multi-directional movement of the UV inkjet printing module 3: The UV inkjet printing module 3 can move freely in the first direction and the second direction. This flexibility enables it to accurately print patterns of various sizes and shapes, greatly improving the adaptability and flexibility of printing. Customized printing: Due to the flexibility of inkjet printing technology, it is easier to achieve small-batch, multi-variety customized production to meet the market demand for personalized products. (3) Optimized belt clamping and fixing: Stable winding method: The belt 5 to be printed is wound around the outer periphery of the first hanging belt assembly 22 and the second hanging belt assembly 23. This design ensures the stability of the belt during the printing process and reduces printing problems caused by loosening or falling off of the belt. Adjustable tensioning mechanism: The first and second hanging belt assemblies 23 are slidably connected to the guide rail 24 and relatively locked, which facilitates the adjustment of the tension of the belt 5 to be printed, ensuring the printing quality while improving the convenience of operation. (4) Environmental protection and sustainability: Environmentally friendly ink: The ink used in UV printing is usually more environmentally friendly than traditional silk screen ink. They contain less volatile organic compounds and are less harmful to operators and the environment. Promote green production: The use of environmentally friendly inks and printing technology helps enterprises achieve green production, meets the requirements of modern society for environmental protection, and also helps to enhance the social image and competitiveness of enterprises. (5) The automation of the printing process is achieved by electrically connecting the UV printing module 3 with the inkjet control cabinet 4.

[0044] Based on the above scheme, the working process of the utility model is as follows: the deviation of the belt lengths of different batches is small, and the position of the first hanging belt assembly 22 is adjusted and then the first hanging belt assembly 22 is locked on the guide rail 24, and the belt 5 to be printed is wrapped around the outer periphery of the first hanging belt assembly 22 and the second hanging belt assembly 23, and the position of the second hanging belt assembly 23 is adjusted and then the second hanging belt assembly 23 is locked on the guide rail 24, so that the position of the belt 5 to be printed where the pattern needs to be printed is tightened, and the quality of subsequent printing is guaranteed, and the coding control cabinet 4 controls the UV printing module 3 to move in the first direction and the second direction to print the set pattern on the belt 5 to be printed.

[0045] Preferably, the belt clamping module 2 includes a cylinder 25, which is fixedly connected to the mounting member 21, and the power output end of the cylinder 25 is fixedly connected to the second hanging belt assembly to achieve sliding between the second hanging belt assembly and the guide rail 24 and relative locking. The cylinder 25 is used to adjust the second hanging belt assembly 23 to tighten the belt 5 to be printed. If the position between the first hanging belt assembly 22 and the second hanging belt assembly 23 is designed to be just the right length for the belt 5 to be printed, it will be very difficult to wind it. After winding, it is convenient to use the cylinder 25 to tighten the belt 5 to be printed.

[0046] Further preferably, the inkjet control cabinet 4 is electrically connected to the cylinder 25 to achieve automatic control for tightening the belt 5 to be printed.

[0047] Preferably, the belt clamping module 2 also includes a driving assembly 26, which includes a connecting rod 261, a first gear 262, a second gear 263 and a driving rod 264, wherein the driving rod 264 extends along a first direction, is mounted on the mounting member 21 and can rotate relative to the mounting member 21, the first gear 262 is mounted on the driving rod 264 and can rotate relative to the driving rod 264, the second gear 263 is engaged with the first gear 262, the connecting rod 261 extends along a second direction, one end of the connecting rod 261 is mounted and connected to the mounting member 21 and can rotate relative to the mounting member 21, the second gear 263 is mounted on one end of the connecting rod 261 and can rotate relative to the connecting rod 261, and the first hanging belt assembly 22 is locked relative to the driving rod 264.

[0048] according to Figure 3 It can be understood that the two first hanging belt components 22 located in the first direction in the figure represent two positions where the first hanging belt components 22 can move.

[0049] Preferably, the driving assembly 26 includes a handle 265, which is mounted on the other end of the connecting rod 261. As the part directly operated by the operator, the design of the handle 265 directly affects the convenience of use. The handle 265 is mounted on the other end of the connecting rod 261, so that the operator can hold the handle 265 more stably during operation, thereby making it easier to rotate the connecting rod 261.

[0050] Based on the above scheme, the working process of the first strap assembly 22 is as follows: the handle 265 is rotated to rotate the connecting rod 261, driving the second gear 263 to rotate, the second gear 263 is meshed with the first gear 262, and the first gear 262 rotates to drive the driving rod 264 to rotate, thereby realizing the sliding of the first strap assembly 22 in the first direction. Since the driving rod 264 extends in the first direction and the connecting rod 261 extends in the second direction, the transmission direction is changed, so it is convenient for the operator to stand in front of the belt clamping module 2 to rotate the handle 265, which is more in line with the usage habits.

[0051] Preferably, the mounting member 21 includes a support frame 266, which extends along the second direction and is sleeved on the outer periphery of the connecting rod 261. Protecting the internal mechanism: The main function of the support frame 266 is to protect the connecting rod 261 and the internal transmission mechanism such as the first gear 262 and the second gear 263 thereon from the influence of the external environment, which can extend the service life of the drive assembly 26 and reduce failures and damage caused by external factors. Enhanced safety: By isolating the internal rotating parts, the support frame 266 can also prevent the user from directly contacting these parts, thereby avoiding potential safety risks such as pinching, scratching, etc. Improved aesthetics: In addition to functional protection, the support frame 266 can also improve the aesthetics and overall texture of the drive assembly 26.

[0052] Preferably, the first hanging belt assembly 22 includes two first hanging belt drums 221 and a first mounting plate 222. The two first hanging belt drums 221 are arranged at intervals on both sides of the driving rod 264 along the third direction. The two first hanging belt drums 221 are respectively fixedly connected to the two ends of the first mounting plate, and the first mounting plate 222 is slidably connected to the guide rail 24. The second hanging belt assembly 23 includes two second hanging belt drums 231 and a second mounting plate 232. The two second hanging belt drums 231 are arranged at intervals on both sides of the driving rod 264 along the third direction. The two second hanging belt drums 231 are respectively fixedly connected to the two ends of the second mounting plate, and the second mounting plate 232 is slidably connected to the guide rail 24. The third direction is perpendicular to the first direction and the second direction. To further improve the adaptability to the belts 5 to be printed of different lengths, the adaptability of the longer belts 5 to be printed is achieved by winding around the outer circumference of the first hanging belt drum 221 and the second hanging belt drum 231.

[0053] Preferably, the driving rod 264 is a screw rod, and the first mounting plate 222 and the second mounting plate 232 are connected to the driving rod 264 through screw nuts. By rotating the screw rod, the distance between the first mounting plate 222 and the second mounting plate 232 can be accurately adjusted, and the cooperation between the screw rod and the screw nut realizes accurate position control. The screw nut system usually has good self-locking properties, and the screw nut can keep its position unchanged, thereby ensuring stability and reliability.

[0054] Preferably, the belt clamping module 2 includes two guide rails 24, on which a slide groove 241 extending in a first direction is provided, and the first mounting plate 222 is provided with two first sliders at intervals along a third direction, and the first sliders are slidably connected to the slide groove 241; the second mounting plate 232 is provided with two second sliders 233 at intervals along the third direction, and the second sliders 233 are slidably connected to the slide groove 241. The two guide rails 24 provide sliding tracks for the first mounting plate 222 and the second mounting plate 232. The two guide rails 24 improve the stability of the sliding of the first hanging belt assembly 22 and the second hanging belt assembly 23, and further improve the smoothness and precision of the sliding.

[0055] Preferably, the belt clamping module 2 includes a support plate 27, which extends along the second direction. The support plate 27 is spaced between the first hanging belt cylinder 221 and the second hanging belt cylinder 231 extending along the first direction, and the support plate 27 is used to support the belt 5 to be printed. Enhanced stability: The support plate 27 extends along the second direction and is spaced between the first hanging belt cylinder 221 and the second hanging belt cylinder 231 extending along the first direction, which effectively provides a support plane for the belt 5 to be printed, reduces the shaking and sagging of the belt during the printing process, and thus enhances the stability of the entire system. Protect the belt: The presence of the support plate 27 prevents the belt from directly contacting the drive assembly 26, and reduces the damage to the belt surface caused by friction or extrusion. Improve printing accuracy: The support plate 27 can ensure that the belt remains flat and stable during the printing process, which is crucial to achieve accurate printing positioning and improve printing quality.

[0057] In summary, the embodiment of the utility model provides a belt UV inkjet coding equipment. First, it adopts inkjet printing technology to replace traditional silk screen printing, effectively reducing the cost of screen preparation and manual replacement, and simplifying the equipment replacement process of different belt printing. Secondly, the UV inkjet printing module 3 can move in two directions to adapt to patterns of different sizes and improve printing flexibility.

In addition, the ink used in UV inkjet printing is environmentally friendly and reduces the impact on operators and the environment. Finally, through the electrical connection with the inkjet coding control cabinet 4, the automation of the printing process is realized to improve production efficiency.

[0058] The above is only a preferred embodiment of the present invention.
