Description

Technical Field

[0001] The present invention relates to the technical field of label printing, in particular to a digital printing machine for label printing. Background Art

[0002] Labels are important identifiers of products, used to provide basic information such as product name, brand, specifications, production date, shelf life, etc. Different batches of products may require different label designs. Digital printing can quickly respond to such changes. Digital printing inks have lower volatile organic compound emissions, reducing air pollution.

[0003] For example, the patent with publication number: CN112874150A discloses a printing paper preprocessing device with a drying and dust removal function, including a workbench, a motor, a fixing nail, a feeding wheel and a drying plate, a dust box is installed on the workbench, and a fixing spring is installed on the dust box, and the fixing spring is installed on the connecting rod, the motor is placed on the workbench, and the motor and the first rotating shaft are connected to each other, and a first pulley and a winding wheel are installed on the first rotating shaft, the limit block is installed on the first rotating shaft, and the first rotating shaft and the winding wheel are fitted together, the printing paper preprocessing device with a drying and dust removal function dries the paper through the heat conduction plate and the heating device, thereby effectively avoiding damage to the printing machine caused by moisture of the paper, and through the up and down movement of the drying plate, the paper is dried more evenly, avoiding damage to the paper in the morning, and the paper is leveled by the leveling wheel, which can effectively ensure the integrity of the printing.

[0004] Although the above-mentioned comparative document dries the paper through the heat conduction plate and the heating device to prevent the paper from being damaged by moisture and causing damage to the printing machine, and removes dust through a fixed dust suction structure, the above-mentioned patent still has some problems: the drying range of the drying plate is fixedly distributed and the dust suction structure is also fixedly set. The range of drying and dust removal is limited, the adjustment flexibility is low, and the various components are relatively independent and cannot achieve collaborative optimization. The drying and moisture-proof effect is single when feeding the label paper. After the label paper is printed, a separate structure is required to dry the surface ink, which increases the overall energy consumption. In addition, during the paper drying process, the dust on the paper surface will be redistributed due to the flow of hot air, but the dust suction structure cannot automatically adjust the working state according to the drying conditions, resulting in poor dust removal effect.

[0005] In response to the above problems, an innovative design was carried out based on the original digital printing machine used for label printing. Summary of the Invention

Three groups of branch pipes 66 are arranged at equal intervals, and the three groups of branch pipes 66 are connected to the dust collection box The box 67 is connected, the bottom surface of the dust collection box 67 is a slope, and the top surface of the workbench 1 is provided with side panels 9. There are two groups of side panels 9 symmetrically distributed about the workbench 1. A circular opening is opened on the surface of one group of side panels 9, and the circular tube 63 passes through the circular opening and is connected to the dust collection box 62. One side of the two groups of side panels 9 is rotatably connected with a driven rod 68. The two groups of driven rods 68 are provided with a spring at one end close to the side panel 9, and one end of the spring is connected to the side panel 9.

[0037] The top of the workbench 1 is provided with an anti-deflection structure 7, which includes a groove 71 opened on the surface of the workbench 1, and a bidirectional motor 72 is fixedly installed inside the groove 71. A screw rod 73 is provided at each end of the bidirectional motor 72, and one end of the screw rod 73 is rotatably connected to the groove 71. There are two groups of screw rods 73 symmetrically distributed, and the surfaces of the two groups of screw rods 73 are respectively reversely threaded. The surfaces of the two groups of screw rods 73 are threadedly connected with moving blocks 74, and the two groups of moving blocks 74 are slidably connected to the groove 71. The tops of the two groups of moving blocks 74 are provided with positioning plates 75, and the positioning plates 75 are L-shaped. The surfaces of the two groups of positioning plates 75 are smooth, which can effectively position the label paper so that it maintains the correct position during transmission and prevents deviation, and can also avoid scratching and damage to the label paper, thereby ensuring printing quality.

[0038] Specifically, when in use, the operator starts the servo motor 3 to drive the feed roller assembly 2 at the output end. The feed roller assembly 2 includes multiple sets of transmission rollers, which are driven by belts. The label paper is then transmitted to the bottom end of the printing assembly 4 through the transmission rollers for printing. The bidirectional motor 72 embedded in the workbench 1 is started and driven. The bidirectional motor 72 is fixedly installed in the groove 71 opened on the surface of the workbench 1. The bidirectional motor 72 drives the screw rods 73 at both ends to rotate. The two sets of screw rods 73 are rotatably connected with the groove 71. The surfaces of the two sets of screw rods 73 are distributed with reverse threads. The two sets of screw rods 73 are respectively threadedly connected with the two sets of moving blocks 74. The two sets of moving blocks 74 are slidably connected to the groove 71. The two sets of moving blocks 74 respectively drive the top positioning plate 75 to move toward the middle. The spacing between the two sets of positioning plates 75 is further adjusted according to the width of the label paper. Since the two sets of positioning plates 75 are L-shaped, both sides of the label paper contact the driven positioning plates 75. The two sets of positioning plates 75 have smooth surfaces, which can effectively position the label paper to keep it in the correct position during transmission and prevent deviation. It can also avoid scratching and damage to the label paper, thereby ensuring printing quality. This adjustable positioning function enhances the adaptability of the digital printing press to label papers of different specifications, improving versatility and flexibility.

[0039] At the same time, when the label paper is conveyed and fed, the fan 52 fixed by the support plate 51 is started, the support plate 51 is fixedly connected to the workbench 1, and the fan 52 inputs the hot air into the inside of the main pipe 54 through the output pipe 53. The hot air is then dispersed and input into the inside of the connecting pipe 55 rotatably connected at both ends through the main pipe 54. There are two groups of fixed plates 10 symmetrically distributed about the workbench 1. The top of each of the two groups of fixed plates 10 is provided with a top plate 56. A pipe groove is opened on the surface of the top plate 56 of one group. The connecting pipe 55 is rotatably connected to the pipe groove, and the top plate 56 of the other group is rotatably connected to the rotating rod 59. The air in the connecting tube 55 enters the interior of the air duct 57. Since the surface of the air duct 57 is provided with a plurality of openings 58, and the openings 58 are distributed on the half of the surface of the air duct 57 close to the transmission roller, the hot air in the air duct 57 is blown through the plurality of openings 58 onto the label paper transmitted by the multiple transmission rollers at the feeding end, thereby drying the damp label paper in time. This is very important for ensuring the dryness of the label paper. Dry label paper can better absorb ink, ensure printing quality, prevent ink smearing and blurred printing caused by damp paper, and improve the clarity and accuracy of the printed product.

[0040] The hydraulic rod 83 inside the long shell 82 is started to drive repeatedly. The long shell 82 is fixedly connected to the workbench 1 through the extension plate 81. The hydraulic rod 83 drives the rack 84 at the output end to move back and forth. The rack 84 slides back and forth in the slide groove 86 opened on the inner wall of the long shell 82 through the slider 85 at the bottom end, and the side of the long shell 82 away from the hydraulic rod 83 is open, which is convenient for the reciprocating movement of the rack 84. The top surface of the long shell 82 is provided with a notch, and the tooth block of the rack 84 protrudes from the notch and reciprocates with the fan-shaped rack 87. The fan-shaped rack 87 swings back and forth through the rotating shaft 88 on one side. The rotating shaft 88 is rotatably connected to the vertical plate 810, and the vertical plate 810 is fixedly connected to the extension plate 81. The fan-shaped rack 87 drives the fixed ring 89 at one end to rotate back and forth. The fixed ring 89 is fixed to the connecting pipe 55, and the connecting pipe 55 drives the air cylinder 57 to swing back and forth. The connecting pipe 55 rotates in the pipe groove opened on the surface of the top plate 56, and the rotating rod 59 provided at one end of the air duct 57 away from the connecting pipe 55 is rotatably connected to the other set of top plates 56, so that the several openings 58 opened on the surface of the air duct 57 swing to blow air, thereby expanding the air-drying range, and can air-dry the label paper more evenly, avoiding the situation of uneven local drying. In addition, the connecting pipe 55, the top plate 56, the air duct 57 and the opening 58 are provided on the upper end of the transmission roller at the discharge end. The connecting pipe 55 is also connected to the main pipe 54. After printing is completed, the label paper can quickly enter the drying area at the discharge end. The hot air blown by the air duct 57 directly acts on the surface of the label paper through the opening 58, which accelerates the drying process of the ink. The ink can be quickly solidified, reducing the occurrence of such smearing phenomenon, and ensuring the clarity and integrity of the label printing.

[0041] At the same time, the dust collection box 62 fixed on the supporting plate 61 on one side of the workbench 1 is started, and a suction pump is provided inside the dust collection box 62, so that the negative pressure inside the circular tube 63 connected to one side of the dust collection box 62 has suction force, and further through multiple sets of dust collection pipes 69, the dust attached to the surface of the label paper to be printed on the surface of the transmission roller is adsorbed into the inside of the dust collection box 67. The bottom end of the dust collection box 67 is an inclined surface, and the multiple sets of dust collection pipes 69 are distributed obliquely, so that the dust sucked into the dust collection box 67 is transmitted to the inside of the long tube 65 through the branch pipes 66 connected to the top of the dust collection box 67 at equal intervals, and then the dust inside the long tube 65 is sucked into the inside of the circular tube 63 through the hose 64, so that the circular tube The dust inside 63 is sucked into the dust box 62 for unified collection and later processing. The circular tube 63 passes through the circular opening opened on the surface of the side plate 9 and is connected to the dust box 62, and driven rods 68 are provided at both ends of the dust box 67. The two sets of driven rods 68 are provided with a spring at one end close to the side plate 9. The spring is used to return the driven rod 68 to its original position. The two sets of driven rods 68 are rotatably connected to the corresponding side plates 9. Since the dust box 67 is close to the wind tube 57 and a driven plate 610 is provided on the side of the wind tube 57 close to the dust box 67, and the wind tube 57 is close to the dust box 67 and a movable plate 510 is provided, and the bottom surface of the driven plate 610 is in contact with the top surface of the movable plate 510, so that the wind tube 57 is driven by the adjustment structure 8 to the dust box. When the fan 57 swings in the direction of 67, the air cylinder 57 drives the movable plate 510 to push the upper driven plate 610 upward, so that the driven plate 610 drives the dust box 67 to be inclined. The inclined surface of the dust box 67 is in the direction corresponding to the blowing direction of the opening 58 on the surface of the air cylinder 57, so that the dust is better sucked into the interior of the dust box 67, and the effect is better. When the swing direction of the air cylinder 57 is opposite to that of the dust box 67, the movable plate 510 does not push the driven plate 610, and the driven plate 610 can be reversed and returned to its original position through the springs at both ends of the driven rod 68, so that the dust box 67 connected to one side of the driven plate 610 is driven to swing repeatedly through the repeated pushing of the movable plate 510. It effectively removes dust and impurities on the label paper, so that when the air duct 57 is working, the position of the dust collection box 67 can be dynamically adjusted according to its swing situation, and the air flow blown out by the air duct 57 can be better utilized to more effectively suck the dust into the dust collection box 67, further enhancing the dust collection effect, improving the dust collection efficiency, ensuring the cleanliness of the printing environment, and providing more favorable conditions for high-quality printing, avoiding dust from mixing into the ink or adhering to the printing equipment during the printing process, affecting the printing quality and equipment performance, keeping the surface of the label paper clean, and helping the ink to adhere evenly to the paper, making the printed patterns and text clearer and more accurate, and improving the quality and aesthetics of the printed products.
