Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, and more specifically to a printing device for woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Woven bags used in different fields will have different texts, instructions, etc. printed on their surfaces; usually, text will be printed on both sides of the woven bags.

[0003] The existing publication number is CN215435563U, and the patent name is a patent document of a printing device for woven bags. It discloses that the turning rod drives the turning plate to turn over. In actual use, the woven bags after printing can be quickly dried to avoid ink blurring, while shortening the natural air drying time and shortening the length of the conveying equipment;

[0004] During the installation test, because hot air drying is used and the overall weight of the woven bag is relatively light, the wind will cause the woven bag to flutter, resulting in the woven bag being unable to be smoothly transported through the hot air drying position. In view of this, we propose a printing device for woven bags. Utility Model Content

[0030] Example:

[0031] This embodiment provides a printing device for woven bags, referring to Figure 1 , including a printing component 1 and a flip component 2. A through hole is opened in the middle of the printing component 1 for allowing the woven bag to pass through and be sprayed. Two printing components 1 are provided for printing on both sides of the woven bag. A flip component 2 is provided between the two printing components 1 to turn the woven bag over for double-sided printing. A drying component 3 is provided at the discharge end of the printing component 1. After the woven bag is printed, hot air blows from top to bottom at the printing position for rapid drying. The drying component 3 includes an air pump 31, which provides continuous airflow. An air outlet of the air pump 31 is provided with an air outlet frame 32. The air outlet frame 32 is equipped with a heating wire, which can heat the passing airflow and blow it vertically toward the woven bag. An air inlet of the air pump 31 is provided with an air suction frame 33. When the air outlet frame 32 continues to discharge air, the air below the air outlet frame 32 will be sucked in to avoid turbulence of the air flow here, and the woven bag will be sucked downward to prevent the woven bag from floating.

[0032] In a further embodiment, referring to Figure 2The air outlet frame 32 is provided with an air outlet (not shown in the figure) on the side facing the air suction frame 33. The air outlet is vertical and the air is discharged. The strip-shaped air outlet frame 32 can ensure the uniform dispersion of the air outlet. The air outlet frame 32 is located on the side of the air outlet close to the printing component 1 and is fixedly installed with an inclined guide strip 37, which can block the airflow and prevent excessive hot air from blowing into the printing component 1, thereby ensuring the stability of the inkjet direction during inkjet printing and preventing the airflow from affecting the normal printing.

[0033] In a further embodiment, referring to Figure 4 The inclined guide bar 37 adopts a triangular prism structure. At the same time, the bottom surface of the inclined guide bar 37 is inclined toward the flip component 2, which can guide the airflow to the right, so that the woven bag is blown to the right, ensuring that the woven bag moves smoothly to the flip component 2 position and ensuring the stable material transfer of the woven bag.

[0034] In a further embodiment, referring to Figure 3 A slope 34 is provided at the top of the suction frame 33 near the flip assembly 2. The setting of the slope 34 allows the woven bag to be guided downward to ensure that the woven bag is smoothly moved to the flip assembly 2. A suction port 35 is provided at the position of the slope 34 to draw air downward to prevent the woven bag from being blown and flying when passing through.

[0035] In a further embodiment, referring to Figure 4 There are multiple air suction ports 35, which can cover the entire woven bag, ensuring that the air suction ports 35 can stably suck the woven bag downward, further improving the passing stability of the woven bag, and the multiple air suction ports 35 are equidistantly arranged at the inclined surface 34.

[0036] In a further embodiment, referring to Figure 3 A fin 36 is fixedly installed on the inclined surface 34 , and the fin 36 is vertically arranged. In addition, there are multiple fins 36 . When the woven bag passes through, the fin 36 can be interspersed between adjacent suction ports 35 to prop up the woven bag and ensure that the surrounding air can be sucked by the air pump 31 through the suction port 35 .

[0037] In a further embodiment, referring to Figure 4 The top surface of the fin 36 is higher than the inclined surface 34, which can ensure that the woven bag can be set up to avoid sticking to the suction port 35, prevent the woven bag from being sucked by force, and ensure the smooth passage of the woven bag. The suction frame 33 is provided with a bearing plate 39 at one end close to the flip component 2 to compensate for the gap between the suction frame 33 and the flip component 2, prevent the woven bag from falling into the gap between the suction frame 33 and the flip component 2, and ensure the smooth passage of the woven bag.

[0038] The air pump, printing assembly and flip assembly involved in the embodiments are existing products produced by the manufacturer, and their supporting control systems, solenoid valves, control switches and circuit pipelines can also be provided by the manufacturer. In addition, the power supply module, circuit and electronic components and control module involved in the utility model are all existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
