Description

Technical Field

[0001] The utility model relates to the technical field of packaging printing, in particular to an environment-friendly packaging printing device. Background Art

[0002] Packaging printing is printing with various packaging materials as carriers, printing decorative patterns, pictures or texts on the packaging to make the product more attractive or more illustrative, so as to play the role of transmitting information and increasing sales. A packaging printing device is a device that transfers the ink of the graphics and texts on the printing plate to packaging materials such as packaging boxes and wrapping papers, performs surface printing on special packaging products, and then packages the printed products, making the printed products more intuitive and reflecting the characteristics of the products.

[0003] At present, most printing devices are provided with a filtering device to suck the harmful gases generated during the drying process after product printing and discharge them after filtration to avoid polluting the working environment. However, during the use of the filtering device on the existing printing device, most of the filtering devices are fixedly installed and do not have the function of height adjustment, so that the suction port position of the filtering device for harmful gases is fixed. When the distance between the suction port of the filtering device and the conveying platform of the printed product is small, if the printed product is a small paper product, it is easy to cause the paper product to be sucked. If the printed product is large, the suction port of the filtering device is likely to block the conveying of the product, thereby reducing the practicability of the device.

[0004] Therefore, it is necessary to provide an environment-friendly packaging printing device to solve the above technical problems. Content of the Utility Model

A filtering component is arranged on the top of the shielding frame 2. Through the coordinated use of structures such as the main body 1 of the packaging and printing equipment, the shielding frame 2, the support plate 5, the air boxes 7, the suction fan 10, the heating box 11, the connecting pipe 15, the solenoid valve 17, the electric control box 22 and the second hose 25, harmful gases can be filtered and heated and then blown out from a plurality of blowing nozzles 8 to carry out the drying work of printed products, improving the utilization of energy. At the same time, when the activated carbon filter plates 16 in the two sealed filter boxes 14 need to be replaced, the replacement work can be carried out separately, and the operation of the device does not need to be stopped during the replacement process, thereby improving the filtering effect of harmful gases.

[0031] A sealing ring 12 is embedded inside the slot 4. Through the arrangement of the sealing ring 12, the sealing between the support plate 5 and the slot 4 can be achieved, avoiding the leakage of harmful gases from the gap between the support plate 5 and the inner wall of the slot 4. A guiding plate 13 is fixedly connected inside the blanking groove 3.

[0032] The filtering component includes two sealed filter boxes 14 and two connecting pipes 15. The two sealed filter boxes 14 are both fixedly connected to the top of the shielding frame 2. A plurality of activated carbon filter plates 16 are arranged inside the two sealed filter boxes 14. The two connecting pipes 15 are respectively fixedly communicated with the front and back of the two sealed filter boxes 14. Two solenoid valves 17 are arranged on the connecting pipe 15. One of the connecting pipes 15 is fixedly communicated with the blowing end of the suction fan 10, and the other connecting pipe 15 is fixedly communicated with the back of the heating box 11.

[0033] The conveying component includes two conveying rollers 19. The two conveying rollers 19 are both rotatably connected between the front and back inner walls of the shielding frame 2. A conveyor belt 20 is drivingly connected between the outer surfaces of the two conveying rollers 19. A motor 21 is fixedly installed on the front surface of the shielding frame 2, and the output end of the motor 21 is fixedly connected to one end of one of the conveying rollers 19.

[0034] Working principle: When in use, first adjust the heights of the two bellows 7 according to the product to be printed. That is, start the cylinder 6 through the electric control box 22, make its telescopic end extend or contract, drive the support plate 5 to move up and down inside the slot 4, and the support plate 5 drives structures such as the two bellows 7, several blowing nozzles 8 and several suction heads 9 fixedly connected thereto to move synchronously, so as to adjust the heights of the two bellows 7, the blowing nozzles 8 and the suction heads 9. Then start the motor 21 through the electric control box 22, make its output end drive one of the conveying rollers 19 to rotate, and under the cooperation of the other conveying roller 19, make the conveyor belt 20 rotate. Then place the product to be printed into the packaging and printing equipment main body 1, and the packaging and printing equipment main body 1 performs printing work on the product, and after printing is completed, it drops onto the conveyor belt 20 and is conveyed towards the discharge chute 3;

[0035] When the printed product is conveyed by the conveyor belt 20, the heating wire 18 and the suction fan 10 can be started. After the heating wire 18 is started, it heats the gas. After the suction fan 10 is started, its suction end evacuates the gas in the corresponding bellows 7 from the hose one 24, making the bellows 7 generate negative pressure, so that several suction heads 9 on the bellows 7 generate suction force. The evacuated gas is blown out from the blowing end of the suction fan 10, passes through the connected connecting pipe 15, the sealed filter box 14, the heating box 11, the hose two 25 and the other bellows 7, and then blows out from several blowing nozzles 8. At the same time, the gas is heated by the heating wire 18 after passing through the heating box 11, so that the gas blown out from several blowing nozzles 8 is hot air. Furthermore, during the conveying process of the printed product, it can be heated by the hot air blown out from several blowing nozzles 8, so that the printed ink dries quickly. The harmful gases generated during the ink drying process can be inhaled by several suction heads 9 and conveyed to the two sealed filter boxes 14, and the harmful substances in the gas are adsorbed and filtered by the activated carbon filter plates 16;

[0036] When the activated carbon filter plates 16 in the sealed filter box 14 need to be replaced after long-term use, first close the solenoid valves 17 on the front and back of one of the sealed filter boxes 14 through the electric control box 22, so that no gas flows through this sealed filter box 14, and the gas filtration work is carried out by the activated carbon filter plates 16 in the other sealed filter box 14. Then the sealed filter box 14 can be opened to perform the replacement work of the activated carbon filter plates 16. By repeating the operation, the replacement work of the activated carbon filter plates 16 in the two sealed filter boxes 14 can be carried out respectively during the gas filtration process.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
