Description

Technical Field

[0001] This utility model relates to the field of label printing technology, and in particular to a flexographic printing machine for QR code labels with automatic correction function. Background Technology

[0002] A flexographic printing press for QR code labels is a device specifically designed for printing QR code labels. It uses flexographic printing technology, in which ink is first applied to a printing plate, and then the ink on the printing plate is transferred to the substrate (such as paper, film, etc.) by an ink transfer roller, thus completing the printing process.

[0003] For QR code label flexographic printing machines, through precise plate-making and printing processes, the QR code pattern and other relevant information are accurately printed onto the label material. Compared with the engraving plate-making of gravure printing, it does not require complex engraving equipment and expensive metal plates, thus reducing plate-making costs.

[0004] Through long-term use and observation, it was found that during the printing of QR code labels using a flexographic printing press, the relative position of the printing paper and the inking roller shifted, causing the printed pattern to be inaccurately positioned on the paper. This resulted in the QR code being unable to be correctly scanned and recognized, affecting the label's functionality.

[0005] To address this, we propose a flexographic printing machine for QR code labels with automatic correction functionality. Utility Model Content

[0006] The technical solution of this utility model is:

[0007] A flexographic printing machine for QR code labels with automatic correction function includes a conveyor base, a first motor mounted in the middle of the side wall of the conveyor base; a conveyor belt fixedly connected to the output end of the first motor; the conveyor belt rotating inside the conveyor base; a pair of upright plates fixed to the top of the conveyor base; the pair of upright plates symmetrically arranged on both sides of the conveyor belt; a fixing component provided in the middle of the side wall of the upright plate, which can fix the printing paper conveyed by the conveyor belt; a flexographic printing machine body mounted on the top of the upright plate; an ink transfer roller rotatably connected to the middle of the inner side wall of the flexographic printing machine body; a material box fixed to the top of the conveyor base; a correction component provided in the middle of the side wall of the material box, which can correct the position of the printing paper placed inside the material box; a drying component provided on the top of the upright plate, which can dry the QR code labels printed by the ink transfer roller; the correction component includes a pair of first electric push rods; the pair of first electric push rods symmetrically fixed on the side wall of the material box. A guide plate is fixedly connected to the output end of the first electric push rod; the guide plate is located inside the material box; a second motor is mounted in the middle of the side wall of the material box; a first movable roller is fixedly connected to the output end of the second motor; a leveling roller is installed in the middle of the side wall of the first movable roller; this step, by setting up the material box, the first electric push rod, and the guide plate, can correct the position of the printing paper on the conveyor belt, thereby correcting the position of the label printed on the printing paper, reducing waste caused by inaccurate positioning, improving material utilization, and by precisely controlling the printing position of the label, printing materials can be used more rationally, reducing material edge waste and unnecessary cutting, and reducing production costs. By setting up the material box, the second motor, the first movable roller, and the leveling roller, the number of printing papers during printing can be limited, reducing the impact of printing paper piling up on the ink printing effect, while allowing each sheet of paper enough time for the ink to dry, ensuring that the printed pattern is clear, the color is bright, and the adhesion is firm.

[0008] In a further technical solution, the fixing component includes a channel; the channel is formed on the side wall of the upright plate; a support rod is fixed in the middle of the inner side wall of the channel; a movable ring is slidably connected to the middle of the side wall of the support rod; a connecting plate is fixedly connected to the middle of the side wall of the movable ring; a second electric push rod is assembled on the top of the connecting plate; a fixing plate is fixedly connected to the output end of the second electric push rod; the fixing plate is located above the conveyor belt; multiple springs are fixed between the upright plate and the movable ring. This step, by setting up the channel, support rod, movable ring, connecting plate, second electric push rod, fixing plate, and springs to fix the printing paper, can ensure that the QR code label is accurately printed in the predetermined position, reduce the problem of misregistration of color, overlapping patterns, or uneven gaps caused by displacement of the printing paper during the printing process, and help improve the reading rate of the QR code and the overall quality of the label.

[0009] In a further technical solution, the air-drying assembly includes an air-drying box; the air-drying box is fixed to the top of the upright plate; an air outlet is fixedly connected to the middle of the side wall of the air-drying box; an air inlet pipe is provided at the bottom of the air-drying box; the air inlet pipe is located above the conveyor belt; the air-drying box, air outlet, and air inlet pipe are all hollow and interconnected; this step of setting up the air-drying box, air outlet, and air inlet pipe can quickly remove the solvent or moisture in the ink by blowing out dry air, so that the ink reaches a dry state in a short time, thereby allowing subsequent processing or stacking, effectively shortening the printing cycle and improving the overall production efficiency.

[0010] In a further technical solution, a pair of fixed rods are fixed in the middle of the side wall of the material box; a second movable roller is rotatably connected between the pair of fixed rods; a take-up roller is installed in the middle of the side wall of the second movable roller; a synchronous belt is drivingly connected between the second movable roller and the first movable roller; and an adhesive tape is rotatably connected between the take-up roller and the leveling roller. This step of setting up fixed rods, a second movable roller, a take-up roller, a synchronous belt, and adhesive tape can remove dust, impurities, or grease and other contaminants by cleaning the surface of the printing paper, so that the ink can be evenly covered on the paper, thereby improving the clarity and color uniformity of the printed pattern. Moreover, contaminants will react with the ink during the printing process or form uneven areas on the paper surface, resulting in defects such as spots, missing prints, and smearing. This setting can effectively reduce the occurrence of these problems and improve the quality and appearance of the printed products.

[0011] In a further technical solution, an observation window is provided in the middle of the side wall of the feeding box; the observation window is made of transparent material; this step allows the staff to intuitively view the remaining amount of paper in the feeding box through the observation window without opening the feeding box or stopping the machine for inspection, which helps to promptly detect whether the paper needs to be replenished.

[0012] In a further technical solution, an elastic pad is installed at the bottom of the fixing plate; the elastic pad is made of elastic material; this step can buffer the pressure of the fixing plate on the printing paper by setting the elastic pad, reduce the pressure of the fixing plate directly squeezing the printing paper, and reduce the indentation, damage or deformation of the paper surface caused by the fixing plate directly squeezing the printing paper, effectively protecting its integrity and surface quality.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a feeding box, a first electric push rod, and a guide plate, the position of the printing paper on the conveyor belt can be corrected, thereby correcting the position of the label printed on the printing paper, reducing waste caused by inaccurate positioning, improving material utilization, and by precisely controlling the printing position of the label, printing materials can be used more rationally, reducing material waste at the edges and unnecessary cutting, and lowering production costs. By setting up a feeding box, a second motor, a first movable roller, and a leveling roller, the number of printing papers during printing can be limited, reducing the impact of printing paper piling up on the ink printing effect, while allowing each sheet of paper enough time for the ink to dry, ensuring that the printed pattern is clear, the color is bright, and the adhesion is firm.

[0015] By setting up channels, support rods, movable rings, connecting plates, second electric push rods, fixing plates, and springs to fix the printing paper, it can be ensured that the QR code label is accurately printed in the predetermined position. This reduces problems such as misregistration of colors, overlapping patterns, or uneven gaps caused by displacement of the printing paper during the printing process, and helps to improve the reading rate of QR codes and the overall quality of labels.

Detailed Implementation

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0023] like Figures 1 to 4 As shown, a flexographic printing machine for QR code labels with automatic correction function includes a conveyor base 1, a first motor 11 mounted in the middle of the side wall of the conveyor base 1, a conveyor belt 12 fixedly connected to the output end of the first motor 11, the conveyor belt 12 rotating inside the conveyor base 1, a pair of upright plates 13 fixedly fixed to the top of the conveyor base 1, the pair of upright plates 13 symmetrically arranged on both sides of the conveyor belt 12, a fixing component provided in the middle of the side wall of the upright plate 13, the fixing component can fix the printing paper conveyed by the conveyor belt 12, a flexographic printing machine body 14 mounted on the top of the upright plate 13, an ink transfer roller 15 rotatably connected to the middle of the inner side wall of the flexographic printing machine body 14, a material box 16 fixedly fixed to the top of the conveyor base 1, a correction component provided in the middle of the side wall of the material box 16, the correction component can correct the position of the printing paper placed inside the material box 16, and a drying component provided on the top of the upright plate 13, the drying component can dry the QR code labels printed by the ink transfer roller 15.

[0024] The working principle of the above technical solution is as follows:

[0025] The staff places the printing paper for the QR code labels to be printed inside the material box 16, and then activates the correction component. The correction component corrects the printing paper being conveyed by the conveyor belt 12, making it move directly in front of the inking roller 15. At the same time, the fixing component fixes the corrected printing paper. When the printing paper moves to below the inking roller 15, the inking roller 15 applies ink to the printing paper, so that the QR code label is printed on the printing paper. At this time, the staff activates the drying component, which quickly dries the ink on the printing paper, so that the QR code label is clearly printed on the printing paper.

[0026] like Figures 1 to 4 As shown, the correction assembly includes a pair of first electric actuators 2; the pair of first electric actuators 2 are symmetrically fixed on the side wall of the material box 16; a guide plate 21 is fixedly connected to the output end of the first electric actuator 2; the guide plate 21 is located inside the material box 16; a second motor 22 is assembled in the middle of the side wall of the material box 16; a first movable roller 23 is fixedly connected to the output end of the second motor 22; a smoothing roller 24 is installed in the middle of the side wall of the first movable roller 23.

[0027] The worker places the printing paper for the QR code labels to be printed inside the material box 16, and then activates a pair of first electric push rods 2. The first electric push rods 2 push the guide plates 21 to move inside the material box 16. At this time, the pair of guide plates 21 push the printing paper from both sides to the center area of ​​the conveyor belt 12, so that it is moved by the conveyor belt 12. When the printing paper passes through the material box 16 and moves to the bottom of the leveling roller 24, the distance between the leveling roller 24 and the conveyor belt 12 limits the number of sheets of printing paper that can pass through, so that the printing paper is conveyed one sheet at a time to the bottom of the inking roller 15. This step can be corrected by setting up the material box 16, the first electric push rods 2, and the guide plates 21. The position of the printing paper on the conveyor belt 12 is used to correct the position of the label printed on the printing paper, reduce waste caused by inaccurate positioning, improve material utilization, and make more rational use of printing materials by precisely controlling the printing position of the label, reducing material waste at the edges and unnecessary cutting, and reducing production costs. By setting up the feeding box 16, the second motor 22, the first movable roller 23 and the leveling roller 24, the number of printing papers during printing can be limited, reducing the impact of printing papers piling up on the ink printing effect. At the same time, each sheet of paper can have enough time for the ink to dry, ensuring that the printed pattern is clear, the color is bright and the adhesion is firm.

[0028] like Figures 1 to 3 As shown, the fixing assembly includes a channel 3; the channel 3 is formed on the side wall of the upright plate 13; a support rod 31 is fixed in the middle of the inner side wall of the channel 3; a movable ring 32 is slidably connected to the middle of the side wall of the support rod 31; a connecting plate 33 is fixedly connected to the middle of the side wall of the movable ring 32; a second electric push rod 34 is assembled on the top of the connecting plate 33; a fixing plate 35 is fixedly connected to the output end of the second electric push rod 34; the fixing plate 35 is located above the conveyor belt 12; and multiple springs 36 are fixed between the upright plate 13 and the movable ring 32.

[0029] As the printing paper moves outward through the leveling roller 24, the operator activates a pair of second electric push rods 34. At this time, the second electric push rods 34 drive the fixing plate 35 to move downward until the fixing plate 35 presses onto the printing paper, fixing the printing paper onto the conveyor belt 12. When the conveyor belt 12 moves the printing paper, the printing paper will drive the fixing plate 35, the second electric push rods 34, and the connecting plate 33 to move synchronously, so that the connecting plate 33 drives the movable ring 32 to slide along the support rod 31. This step, by setting the groove 3, the support rod 31, the movable ring 32, the connecting plate 33, the second electric push rod 34, the fixing plate 35, and the spring 36 to fix the printing paper, can ensure that the QR code label is accurately printed in the predetermined position, reduce the problem of misregistration of color, overlapping patterns, or uneven gaps caused by displacement of the printing paper during the printing process, and help improve the reading rate of the QR code and the overall quality of the label.

[0030] like Figure 1 and Figure 3As shown, the air drying assembly includes an air drying box 4; the air drying box 4 is fixed to the top of the upright plate 13; an air outlet 41 is fixed to the middle of the side wall of the air drying box 4; an air inlet pipe 42 is opened at the bottom of the air drying box 4; the air inlet pipe 42 is located above the conveyor belt 12; the air drying box 4, the air outlet 41 and the air inlet pipe 42 are all hollow and connected.

[0031] The staff connects the air outlet 41 to the blower. Since the drying box 4, the air outlet 41, and the air inlet pipe 42 are connected, the airflow will enter the drying box 4 through the air outlet 41 and flow from the air inlet pipe 42 to the surface of the fixed printing paper, thereby drying the ink on it. This step, by blowing out dry air from the drying box 4, the air outlet 41, and the air inlet pipe 42, can quickly remove the solvent or moisture from the ink, allowing the ink to reach a dry state in a short time, so that it can be processed or stacked later, effectively shortening the printing cycle and improving the overall production efficiency.

[0032] like Figures 1 to 3 As shown, a pair of fixed rods 5 are fixed in the middle of the side wall of the material box 16; a second movable roller 51 is rotatably connected between the pair of fixed rods 5; a take-up roller 52 is installed in the middle of the side wall of the second movable roller 51; a synchronous belt 53 is connected between the second movable roller 51 and the first movable roller 23; and an adhesive tape 54 is rotatably connected between the take-up roller 52 and the smoothing roller 24.

[0033] The operator starts the second motor 22, which drives the first movable roller 23 to rotate. The rotation of the first movable roller 23 drives the leveling roller 24 to rotate, causing the leveling roller 24 to unwind the adhesive sticker 54 on its side wall. At this time, the adhesive sticker 54 cleans the printing paper it contacts. Simultaneously, the rotation of the first movable roller 23 drives the synchronous belt 53 to rotate, which in turn drives the take-up roller 52 to rotate, causing the take-up roller 52 to rewind the used adhesive sticker 54. This step, with its fixed rod 5, second movable roller 51, take-up roller 52, synchronous belt 53, and adhesive sticker 54, cleans the surface of the printing paper, removing dust, impurities, or grease, allowing the ink to evenly cover the paper. This improves the clarity and color uniformity of the printed pattern. Furthermore, contaminants can react with the ink during printing or form uneven areas on the paper surface, leading to defects such as spots, omissions, and smearing. This setup effectively reduces these problems, improving the quality and appearance of the printed product.

[0034] like Figure 3 As shown, an observation window 6 is provided in the middle of the side wall of the material box 16; the observation window 6 is made of transparent material; this step allows the staff to intuitively see the remaining amount of paper in the material box 16 through the observation window 6 without opening the material box 16 or stopping the machine for inspection, which helps to promptly detect whether the paper needs to be replenished.

[0035] like Figure 3 As shown, an elastic pad 7 is installed at the bottom of the fixing plate 35; the elastic pad 7 is made of elastic material; this step can buffer the pressure of the fixing plate 35 on the printing paper by setting the elastic pad 7, reduce the pressure of the fixing plate 35 on the printing paper, and reduce the indentation, damage or deformation of the paper surface caused by the fixing plate 35 directly squeezing the printing paper, effectively protecting its integrity and surface quality.

[0036] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
