[0002] Packaging bags are used to package various items, making them easy to transport and store during production and distribution. They are widely used in daily life and industrial production. In addition to their inherent packaging properties, businesses also utilize packaging bags for advertising, necessitating the use of printing equipment during the bag production process.

[0003] Most existing printing devices print on packaging bags by dipping a printing plate in ink and then pressing the printing plate down to the surface of the packaging bag. However, this intermittent printing and ink supply method results in low printing efficiency and cannot achieve continuous ink supply, thereby affecting the printing and ink supply efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a printing ink feeding device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a printing ink feeding device, comprising two vertical plates for mounting a packaging bag printing device and two winding rollers, a horizontal plate fixedly mounted between the two vertical plates, a conveyor belt mounted between the two vertical plates, and the horizontal plate slidingly positioned inside the conveyor belt;

[0006] Two first traction rollers and a second traction roller are symmetrically installed between the two vertical plates, and the outer sides of the first traction roller and the second traction roller are both slidably sleeved with printing strips;

[0007] A vertical groove is formed on one side of each of the two vertical plates, a slider is slidably connected to the inside of the vertical groove, a pressure plate is fixedly connected between the two sliders, two mounting plates are symmetrically mounted on the bottom of the pressure plate, and a printing roller is rotatably mounted between the two mounting plates, an ink supply cylinder is fixedly connected to the bottom surface of the pressure plate, an arc-shaped hole is formed at the lower end of the ink supply cylinder, and the arc-shaped hole is slidably fitted to the side wall of the printing roller, and a connecting pipe is connected to the side wall of the ink supply cylinder;

[0008] The inner lower ends of the two vertical slots are fixedly connected with tension springs, and the top surfaces of the tension springs are fixedly connected to the bottom of the sliding block.

[0009] Preferably, two limiting blocks are symmetrically fixedly connected to the side wall of the sliding block, and two limiting grooves are symmetrically opened on the inner wall of the vertical groove.

[0010] Preferably, the two limiting blocks fixedly connected to the side wall of the slider are respectively slidably connected to the inside of the two limiting grooves opened on the inner wall of the vertical groove.

[0011] Preferably, a damping rod is fixedly connected to the inner lower end of the vertical slot, and the top surface of the damping rod is fixedly connected to the bottom of the slider.

[0012] Preferably, the damping rod is slidably sleeved inside the tension spring.

[0013] Preferably, a rubber pad is fixedly connected to the side wall of the arc-shaped hole at the lower end of the ink supply cylinder, and the rubber pad is slidably fitted to the side wall of the printing roller.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The printing ink-feeding device benefits from the arrangement of the first traction roller, the second traction roller, the printing strip, the printing roller and other structures. The printing strip is caused to circulate by the first traction roller and the second traction roller, and the printing strip is penetrated by printing holes, so that the contents of the printing holes on the printing strip are printed on the surface of the packaging bag. At the same time, it benefits from the arrangement of the pressure plate, the ink supply cylinder and other structures. The pressure plate, the ink supply cylinder and the printing roller are installed inside the printing strip, and the printing roller is downwardly fitted to the side wall of the printing strip and presses the printing strip downward to fit the surface of the packaging bag, thereby pressing the ink on the printing roller down to the surface of the printing roller and printing on the surface of the packaging bag. At the same time, it benefits from the arrangement of the slider and the tension spring. The slider and the pressure plate can be pulled downward by the tension spring to drive the printing roller to press the printing strip downward, thereby further improving the fitting effect between the printing strip and the surface of the packaging bag, thereby improving the printing effect.

[0016] The printing ink supply device benefits from the arrangement of an ink supply cylinder. An arc-shaped hole is provided at the lower end of the ink supply cylinder, and the arc-shaped hole is slidably fitted on the surface of the printing roller. Ink is then introduced into the ink supply cylinder through a connecting tube on the side wall of the ink supply cylinder and contacts the printing roller. Simultaneously, the arc-shaped hole in the ink supply cylinder slidably fits the surface of the printing roller, thereby achieving continuous ink supply to the printing roller while preventing excessive ink supply.

[0017] Compared with the prior art, the printing ink-feeding device can effectively feed ink to the printing roller and can also continuously print on the surface of the packaging bag, thereby greatly improving the printing and ink-feeding effects of the packaging bag.

[0026] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0029] like Figures 1 to 5 The main structure of a printing ink feeding device shown is as follows: two vertical plates 1 and two winding rollers 2 are installed for packaging bag printing. A horizontal plate 4 is fixedly installed between the two vertical plates 1, and a conveyor belt 3 is installed between the two vertical plates 1. The horizontal plate 4 is slidably located inside the conveyor belt 3, and the conveyor belt 3 is slidably wound around the outside of the horizontal plate 4, thereby improving the stability of the packaging bag when it is pressed down;

[0030] Two first pulling rollers 5 and a second pulling roller 6 are symmetrically installed between the two vertical plates 1, and a printing strip 13 is slidably sleeved on the outer sides of the first pulling roller 5 and the second pulling roller 6. The first pulling roller 5 and the second pulling roller 6 are both symmetrically arranged, and the first pulling roller 5 and the second pulling roller 6 are arranged up and down, so that there is a certain space in the middle of the printing strip 13;

[0031] A vertical groove 10 is provided on one side of each of the two vertical plates 1. A slider 11 is slidably connected to the inner side of the vertical groove 10. A pressure plate 7 is fixedly connected between the two sliders 11. Two mounting plates are symmetrically installed at the bottom of the pressure plate 7, and a printing roller 9 is rotatably installed between the two mounting plates. Thanks to the pressure plate 7, the printing roller 9 and other structures being installed inside the printing strip 13, the printing roller 9 slides and fits against the side wall of the printing strip 13, so that the printing strip 13 is pressed down by the printing roller 9 to fit against the surface of the packaging bag. The surface of the printing roller 9 is embossed, and the content to be printed is opened through the printing strip 13. At the same time, ink is evenly fed to the surface of the printing roller 9 through the ink cylinder 8. At the same time, the printing roller 9 presses the printing strip 13 down to contact the packaging bag on the top surface of the conveyor belt 3 below and print it.

[0032] The bottom surface of the pressure plate 7 is fixedly connected to an ink supply cylinder 8, and an arc-shaped hole is opened at the lower end of the ink supply cylinder 8, and the arc-shaped hole is slidably fitted on the side wall of the printing roller 9, and the side wall of the ink supply cylinder 8 is connected with a connecting pipe. Thanks to the arrangement of the ink supply cylinder 8, an arc-shaped hole is opened at the lower end of the ink supply cylinder 8, and the arc-shaped hole is slidably fitted on the surface of the printing roller 9. At this time, ink is passed into the interior of the ink supply cylinder 8 through the connecting pipe on the side wall of the ink supply cylinder 8 and contacts the printing roller 9. At the same time, thanks to the arc-shaped hole opened in the ink supply cylinder 8 and slidingly fitted on the surface of the printing roller 9, continuous ink feeding to the printing roller 9 is achieved while preventing excessive ink feeding.

[0033] A tension spring 12 is fixedly connected to the lower end of the two vertical grooves 10, and the top surface of the tension spring 12 is fixedly connected to the bottom of the slider 11. Thanks to the arrangement of the slider 11 and the tension spring 12, the slider 11 and the pressure plate 7 can be pulled downward by the tension spring 12 and the printing roller 9 can be driven to press the printing strip 13 downward, thereby further improving the fitting effect between the printing strip 13 and the surface of the packaging bag, thereby improving the printing effect.

[0034] Two limit blocks 14 are symmetrically fixedly connected to the side wall of the slider 11, and two limit grooves are symmetrically opened on the inner wall of the vertical groove 10. The two limit blocks 14 fixedly connected to the side wall of the slider 11 are respectively slidably connected to the inside of the two limit grooves opened on the inner wall of the vertical groove 10. Thanks to the setting of the limit blocks 14, the sliding direction of the slider 11 can be effectively limited.

[0035] A damping rod 15 is fixedly connected to the inner lower end of the vertical groove 10, and the top surface of the damping rod 15 is fixedly connected to the bottom of the slider 11. The damping rod 15 is slidably sleeved on the inside of the tension spring 12. Thanks to the setting of the damping rod 15, the damping rod 15 can prevent the vibration generated when the device is in use from being transmitted to the tension spring 12, thereby causing the tension spring 12 to vibrate and directly affect the stability of the downward pressure of the printing roller 9 and the effect of the printed product.

[0036] A rubber pad 16 is fixedly connected to the side wall of the arc-shaped hole at the lower end of the ink supply cylinder 8, and the rubber pad 16 slides and fits against the side wall of the printing roller 9. Thanks to the setting of the rubber pad 16, the rubber pad 16 slides and fits against the side wall of the printing roller 9, so that the excess ink on the surface of the printing roller 9 can be scraped off while the printing roller 9 rotates, thereby further preventing the surface of the printing roller 9 from being over-supplied with ink and affecting the printing effect.

[0037] How it works

[0038] When the printing ink feeding device is used, the printing strip 13 is first looped around between the first traction roller 5 and the second traction roller 6. At this time, because the first traction roller 5 and the second traction roller 6 are both symmetrically arranged, and the first traction roller 5 and the second traction roller 6 are arranged up and down, there is a certain space in the middle of the printing strip 13. At the same time, thanks to the structures such as the pressure plate 7 and the printing roller 9 being installed inside the printing strip 13, the printing roller 9 is slidably fitted to the side wall of the printing strip 13, so that the printing strip 13 is pressed down by the printing roller 9 to fit the surface of the packaging bag, and the printing The surface of the roller 9 is embossed, and the printing strip 13 is penetrated by the content to be printed, and the ink is evenly fed to the surface of the printing roller 9 through the ink supply cylinder 8; thanks to the setting of the ink supply cylinder 8, the lower end of the ink supply cylinder 8 is provided with an arc hole, and the arc hole slides and fits on the surface of the printing roller 9. At this time, the ink is passed into the interior of the ink supply cylinder 8 through the connecting tube on the side wall of the ink supply cylinder 8 and contacts with the printing roller 9. At the same time, thanks to the sliding fit between the arc hole opened in the ink supply cylinder 8 and the surface of the printing roller 9, continuous ink feeding to the printing roller 9 is achieved while preventing excessive ink feeding.
