Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing devices, in particular to a printing device for a laundry detergent packaging bag. Background Art
[0002] The printing device is used to print patterns on laundry detergent packaging bags. The printing device consists of a workbench and a conveyor belt printing mechanism. When printing patterns on laundry detergent packaging bags, the laundry detergent packaging bags are placed on a conveyor belt and moved to the printing mechanism. The printing mechanism uses an inkjet printer to convert colored liquid ink into fine particles through nozzles and spray them onto the packaging bags. These nozzles can quickly sweep across the packaging bags, spraying out countless small ink droplets to form pixels in the image, thereby printing the laundry detergent packaging bags. Thin-film resistors are used to heat the ink, forming bubbles that force the ink droplets to be ejected. When the bubbles disappear, the ink in the nozzles will retract and be replenished with new ink.
[0003] The inventor discovered in his daily work that when the printing device is in use, one side of the laundry detergent packaging bag cannot be printed because the laundry detergent packaging bag is placed on a conveyor belt. When the other side needs to be printed, the laundry detergent packaging bag can only be turned over and placed on the conveyor belt for printing after one side is printed, which may affect the efficiency of printing on both sides of the laundry detergent packaging bag.

The printed side of the packaging bag is moved to the upper inkjet printer. The upper inkjet printer is then started to print the bag, thereby achieving printing on both sides of the packaging bag and improving the printing efficiency as much as possible. This solves the problem that when printing the laundry detergent packaging bag, one side of the laundry detergent packaging bag cannot be printed because the laundry detergent packaging bag is placed on a conveyor belt. When printing is required on the other side, the laundry detergent packaging bag can only be turned over and placed on the conveyor belt for printing after printing on one side is completed, which may affect the printing efficiency on both sides of the laundry detergent packaging bag.

By setting the printing assembly 2, when it is necessary to print on both sides of the laundry detergent packaging bag, the packaging bag passes through the lower rotating roller 22 on the mounting block 21, and then contacts the upper rotating roller 22, and the inkjet printers 25 on the upper and lower sides of the mounting frame 24 are started to print it, and the external The driving roller pulls one end of the packaging bag to move the packaging bag, so that the printing side of the packaging bag moves to the upper inkjet printer 25, and then the upper inkjet printer 25 is started to print it, thereby achieving the effect of printing on both sides of the packaging bag and improving the printing efficiency as much as possible. The upper end of the workbench 1 is fixedly connected with mounting blocks 26 on both sides. The two mounting blocks 26 are located on both sides of the mounting frame 24. Two identical perforated plates 27 are set between the two mounting blocks 26. The two perforated plates 27 on one side of the mounting block 26 are inflated by the hot air inlet mechanism. The air is then ejected from the holes on the surface of the air, thereby drying the packaging bag. A heating box 28 is fixedly connected to one side of the mounting block 26. An electric heating wire 210 is installed on the inner wall of the heating box 28. When the electric heating wire 210 is started, the temperature inside the heating box 28 is increased. An air pump 211 is installed on the upper end of the heating box 28. A long hose 29 is fixedly connected between the heating box 28 and the two perforated plates 27. When the air pump 211 is started, the gas is blown toward the heating box 28. Finally, the hot air is blown into the perforated plates 27 by the long hose 29. A chute 212 is provided on one side of the mounting block 26. The two perforated plates 27 are provided with a chute 212. The perforated plate 27 slides on the inner wall of the slide 212, and the two perforated plates 27 move in the slide 212, thereby changing the distance between the hot air blown out by the perforated plate 27 and the packaging bag. The inner wall of the slide 212 is rotatably connected with a threaded rod 23, and the threaded rod 23 is threadedly connected to the perforated plate 27. The threads at both ends of the threaded rod 23 are opposite. The threaded rod 23 rotates, causing the two perforated plates 27 to move in the slide 212. A drive motor 213 is installed on the top of the mounting block 26. The output end of the drive motor 213 is fixed to the threaded rod 23. Starting the drive motor 213 causes the threaded rod 23 to rotate.

When it is necessary to smooth the upper surface of the packaging bag, the motor that controls the rotation of the conveyor belt 32 under the mounting long plate 31 is started, so that the conveyor belts 32 on both sides rotate, and the circular rollers rotate, thereby smoothing the packaging bag to both sides.
[0032] Working principle:
[0033] When printing patterns on laundry detergent packaging bags, the laundry detergent packaging bags are placed on a conveyor belt and moved to a printing mechanism. The printing mechanism uses an inkjet printer 25 to convert colored liquid ink into fine particles through nozzles and spray them onto the packaging bags. These nozzles can quickly sweep across the packaging bags, spraying countless small ink droplets to form pixels in the image, thereby printing the laundry detergent packaging bags. A thin film resistor is used to heat the ink, forming bubbles that force the ink droplets to be sprayed out. When the bubbles disappear, the ink in the nozzles will retract and be replenished with new ink. When it is necessary to print both sides of the laundry detergent packaging bag, the packaging bag is passed through the lower rotating roller 22 on the mounting block 1 21, and then contacts the upper rotating roller 22. The inkjet printers 25 on the upper and lower sides of the mounting frame 24 are started to print it. One end of the packaging bag is pulled by an external drive roller, so that the packaging bag moves, so that the printed side of the packaging bag moves to the upper inkjet printer 25 (the inkjet printer is an existing market product, and its specific printing method is as a prior art). , I will not go into details here), then start the upper inkjet printer 25 to print on it, thereby achieving printing on both sides of the packaging bag and improving the printing efficiency as much as possible, start the electric heating wire 210 to increase the temperature inside the heating box 28, start the air pump 211 to blow gas to the heating box 28, and finally blow the hot air into the perforated plate 27 through the long hose 29, so that the two perforated plates 27 on one side of the mounting block 26 are inflated and finally ejected from the holes on the air surface, thereby drying the packaging bag, start the driving motor 213 to rotate the threaded rod 23, and the threaded rod 23 rotates, so that the two perforated plates 27 move in the slide 212, and the two perforated plates 27 move in the slide 212, thereby changing the distance between the hot air blown out by the perforated plate 27 and the packaging bag, when it is necessary to smooth the upper surface of the packaging bag, start the motor that controls the rotation of the conveyor belt 32 under the long plate 31, so that the conveyor belts 32 on both sides rotate, so that the circular roller rotates, thereby smoothing the packaging bag to both sides.
