Description

Technical Field

[0001] The invention belongs to the technical field of packaging box printing, and in particular relates to a packaging box production printing device with a drying mechanism. Background Art

[0002] Printing is a technology that transfers ink to the surface of paper, fabric, leather and other materials through processes such as plate making, inking and pressurization to batch reproduce the content of the original manuscripts, such as text, pictures, photos, etc. In order to allow consumers to understand the product without opening the package, it is necessary to print the product name, picture and trademark on the package.

[0003] For example, a printing device for producing food packaging boxes (Announcement No.: CN111661687A) includes a dust removal chamber above the conveyor belt, an adjustable introduction mechanism, a first conveyor roller mechanism, a dust removal roller brush mechanism, a second conveyor roller mechanism and an auxiliary roller mechanism are sequentially arranged in the dust removal chamber along the conveying direction of the conveyor belt, two adjustable auxiliary pressure rollers are installed on the adjustable introduction mechanism, a dust suction device is provided above the dust removal roller brush mechanism, a dust removal roller brush mechanism is provided below the dust suction cover of the dust suction device, a dust removal roller is provided on the dust removal roller brush mechanism, a plurality of mounting grooves are arranged at intervals on the outer periphery of the dust removal roller, a plurality of air holes are arranged between the mounting grooves, the dust removal roller is connected to a dust removal air pump, the dust removal air pump is connected to a hollow cavity, and a brush assembly is installed in the mounting groove. The printing device can automatically guide and position the packaging box, reduce the problem of offset when the paper is input, and reduce the dust on the surface of the paper, thereby improving the printing effect.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the above equipment lacks a mechanism for drying the ink on the surface of the packaging box after printing when used. The ink or pigment often needs time to dry naturally. If there is no special drying mechanism, the ink dries unevenly, which may cause blurring, adhesion or uneven color on the surface of the packaging box, seriously affecting the appearance quality and market acceptance of the product. In addition, the natural drying process is time-consuming and becomes a bottleneck restricting the efficiency of the entire production line. In the absence of a drying mechanism, the production line has to wait for the ink to be completely dry before proceeding to the next step. This not only prolongs the production cycle, but also increases the cost of manpower and time. For this reason, we propose a packaging box production and printing device with a drying mechanism to solve the problems existing in the prior art. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The present invention provides Figure 1-6 A packaging box production printing device with a drying mechanism shown in the figure comprises a box body 1, a conveyor belt 2 is arranged inside the box body 1, inlet and outlet channels 3 for the conveyor belt 2 to pass through are opened on both sides of the box body 1, a cleaning mechanism 4 for cleaning dust on the surface of the packaging box is installed on one side of one group of inlet and outlet channels 3 of the box body 1, and a dust suction mechanism 5 for sucking dust on the surface of the packaging box is installed on one side of the cleaning mechanism 4;

[0031] like Figure 5 As shown, a printing body 6 for printing on the surface of the packaging box is installed on one side of the cleaning mechanism 4, a drying mechanism 7 for drying the printed packaging box is installed on one side of the printing body 6, and a filtering mechanism 8 for filtering the gas inside the box 1 is provided at one end of the box 1;

[0032] The drying mechanism 7 includes a heating box 71, which is fixedly installed on the top of the box body 1. A heating wire 72 is installed inside the heating box 71. One side of the heating box 71 is fixedly connected to a blower 73. One side of the heating box 71 is fixedly connected to an air outlet hood 74 through a pipeline penetrating the box body 1. A diverter shell 75 is installed at the bottom of the air outlet hood 74 to facilitate the extraction of external air by the blower 73 and send it into the heating box 71. The heating wire 72 heats the air in the heating box 71, and transports it to the diverter shell 75 through the air outlet hood 74, and then transports it to the surface of the packaging box through the diverter shell 75.

[0033] Further, if Figure 2 and Figure 3 As shown, the cleaning mechanism 4 includes two groups of electric push rods 41, and the two groups of electric push rods 41 are symmetrically fixedly installed on the inner top of the box body 1. One end of the piston rod of the two groups of electric push rods 41 is fixedly connected to a mounting frame 42, and a cleaning roller brush 44 is rotatably installed inside the mounting frame 42, so that the height of the cleaning roller brush 44 in the mounting frame 42 can be driven to drop by the two groups of electric push rods 41, and the height of the cleaning roller brush 44 can be adjusted according to the specification and thickness of the packaging box.

[0034] Specifically, the cleaning roller brush 44 is located above the conveyor belt 2, and a drive motor 43 is fixedly installed on one side of the mounting frame 42. One end of the output shaft of the drive motor 43 is fixedly connected to one end of the cleaning roller brush 44. The cleaning roller brush 44 is driven by the drive motor 43 to rotate to clean the surface of the packaging box.

[0035] Further, such as Figure 4 As shown, the dust suction mechanism 5 includes a dust collecting box 51, which is fixedly installed at the bottom of the box body 1, and the feed port of the dust collecting box 51 is fixedly connected to a dust hood 52 through a pipeline penetrating the box body 1, and the air outlet of the dust collecting box 51 is fixedly connected to an air suction shell 53, and a negative pressure fan 55 is fixedly installed on one side of the air suction shell 53, and a filter screen 54 is fixedly installed at the air inlet of the air suction shell 53, so that the air in the dust collecting box 51 can be extracted by the negative pressure fan 55, so that the dust hood 52 generates negative pressure to absorb the dust generated by the cleaning mechanism 4 when cleaning the surface of the packaging box, so that the dust enters the dust collecting box 51 and is filtered by the filter screen 54 and remains in the dust collecting box 51.

[0036] Specifically, a discharge port is provided at one side of the dust box 51 , and a dust discharge box 56 is detachably connected to the inside of the discharge port, so that the dust collected in the dust box 51 can be discharged through the dust discharge box 56 .

[0037] Further, such as Figure 6As shown, the filter mechanism 8 includes a filter shell 81, which is fixedly embedded in one end portion of the housing 1, and two sets of exhaust fans 82 are fixedly installed inside the filter shell 81 through a bracket. The top of the filter shell 81 is symmetrically provided with two sets of plug-in slots 83 extending to the inside of the filter shell 81, and the insides of the two sets of plug-in slots 83 are respectively plugged with activated carbon adsorption layers 84 and HEPA high-efficiency filter mesh layers 85, so that the air generated by drying the ink or pigment on the surface of the packaging box by starting the drying mechanism 7 inside the extraction housing 1 through the two sets of exhaust fans 82, and the activated carbon adsorption layer 84 and the HEPA high-efficiency filter mesh layer 85 purify and filter the gas entering the filter shell 81 and then discharge it.

[0038] It is worth noting that the activated carbon adsorption layer 84 can use its porous structure to adsorb small particulate matter, organic pollutants and some harmful gases in the air, such as VOCs (volatile organic compounds), which are often generated during the drying process of ink or pigment;

[0039] The HEPA high-efficiency filter layer 85 can capture particles in the air, especially particles larger than 0.3 microns, with a purification rate of up to 99.97%, thereby effectively removing impurities such as dust, pollen, and bacteria in the air.

[0040] Specifically, a protective net 86 is fixedly embedded on one side of the filter shell 81 located on the HEPA high-efficiency filter layer 85 , and one side of the protective net 86 is flush with the end of the filter shell 81 , so that the protective net 86 can be used to protect the inside of the filter shell 81 .

[0041] Further, such as Figure 1 As shown, an observation window 10 is provided on one side of the box body 1, through which the printed body 6 and the printed packaging box inside the box body 1 can be observed, and a control panel is fixedly installed on one side of the observation window 10, and the control panel is electrically connected to the conveyor belt 2, the electric push rod 41, the drive motor 43, the negative pressure fan 55, the printing body 6, the heating wire 72, the blower 73 and the exhaust fan 82 through wires, so that the electrically connected components can be controlled through the control panel.

[0042] Specifically, a heat insulation board 9 is fixedly installed on the inner top of the box body 1, and the heat insulation board 9 is located between the printing body 6 and the diversion shell 75, so as to separate the drying mechanism 7 from the printing body 6 through the heat insulation board 9, thereby reducing the impact of the drying mechanism 7 on the printing body 6.

[0043] Specifically, a dustproof net is installed at the air inlet of the blower 73 to prevent dust from being sucked into the heating box 71 by the blower 73. A plurality of groups of diversion holes 76 are provided at the bottom of the diversion shell 75 to facilitate uniform blowing of hot air. The hot air in the diversion shell 75 is evenly refined through the plurality of groups of diversion holes 76, so that the hot air can be evenly distributed on the surface of the packaging box.

[0044] Working principle: The conveying of the packaging box is started by the conveyor belt 2, and the height of the cleaning roller brush 44 in the mounting frame 42 is driven to descend by the two sets of electric push rods 41 in the cleaning mechanism 4. The height of the cleaning roller brush 44 is adjusted according to the specification and thickness of the packaging box, and the cleaning roller brush 44 is driven by the driving motor 43 to rotate to clean the surface of the packaging box. The floating dust is sucked by the dust suction mechanism 5 to improve the cleaning effect. The packaging box conveyed on the conveyor belt 2 can be pressed and conveyed to the bottom of the printing body 6 for printing by the auxiliary roller mechanism (not shown in the prior art figure in the referenced document in the background technology);

[0045] After the packaging box is printed, it is further transported to the bottom of the diverter shell 75 in the drying mechanism 7 through the conveyor belt 2, and the outside air is sucked by the blower 73 and sent into the heating box 71. The heating wire 72 heats the air in the heating box 71 and is transported to the diverter shell 75 through the air outlet cover 74. The hot air is evenly refined through several groups of diverter holes 76 at the bottom of the diverter shell 75, so that the hot air can be evenly spread on the surface of the packaging box, thereby enhancing the drying efficiency of the ink or pigment on the surface of the packaging box;

[0046] At the same time, the two sets of exhaust fans 82 in the filtering mechanism 8 are started to extract the air generated by the drying mechanism 7 inside the box 1 to dry the ink or pigment on the surface of the packaging box. The activated carbon adsorption layer 84 and the HEPA high-efficiency filter layer 85 purify and filter the gas entering the filter shell 81 and then discharge it, thereby avoiding the emission of harmful gases and particles generated by the drying of ink or pigment to a certain extent, and reducing pollution to the surrounding environment.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
