An auxiliary device for green and environmentally friendly printing of cardboard boxes

Abstract

This utility model discloses an auxiliary device for green and environmentally friendly printing of cardboard boxes. The auxiliary mechanism includes a frame, on which a controller, a connecting frame, a collection hood, and a pretreatment mechanism, an adsorption mechanism, a drying mechanism, and a temperature control mechanism are respectively connected to the controller. The pretreatment mechanism and the adsorption mechanism are arranged at intervals along the left and right directions. The drying mechanism is located at the end of the connecting frame. The collection hood collects the waste gas generated by the printing machine and transports the waste gas to the pretreatment mechanism for pretreatment. The pretreated waste gas is then processed by the adsorption mechanism. The treated clean air enters the heat exchange plate to exchange heat with the untreated waste gas, thereby increasing the temperature of the clean air. This reduces the temperature of the untreated air, preventing the adsorption effect of the adsorption mechanism from decreasing due to excessive temperature, and also heats the clean air, reducing energy consumption through heat exchange.

Description

Technical Field

[0001] This utility model relates to the field of printing auxiliary device technology, and in particular to an auxiliary device for green and environmentally friendly printing of cardboard boxes. Background Technology

[0002] In the cardboard box printing industry, printing presses require auxiliary equipment for waste gas treatment and printed material drying during operation. Traditionally, waste gas treatment and printed material drying in printing equipment have relied on separate devices, resulting in high energy consumption, insufficient environmental friendliness, and low integration. Specific technical challenges are as follows:

[0003] In traditional cardboard box printing, ink evaporation generates waste gas containing volatile organic compounds, requiring a separate waste gas treatment system. Simultaneously, the printed cardboard boxes need to undergo ink curing in a separate drying system, making these two processes separate equipment systems. This "split-type" design leads to two major problems: first, the equipment occupies a large area, requiring separate installation of waste gas ducts and drying air ducts, increasing the complexity of the workshop layout; second, energy consumption is compounded, as the fans and heating devices of the waste gas treatment equipment and the heat source of the drying system need to operate independently. Especially in small and medium-sized printing plants, the total energy consumption of these two types of equipment accounts for more than 40% of the total energy consumption of the printing process, which is inconsistent with the industry trend of energy conservation and carbon reduction.

[0004] Therefore, this application provides an auxiliary device for green and environmentally friendly printing of cardboard boxes. Utility Model Content

[0005] This utility model provides an auxiliary device for green and environmentally friendly printing of cardboard boxes, which can solve the problems of large equipment footprint and high energy consumption caused by the need for waste gas treatment equipment and printed matter drying equipment for auxiliary operations in traditional printing presses.

[0006] This utility model provides an auxiliary device for green and environmentally friendly printing of cardboard boxes, including:

[0007] The auxiliary mechanism includes a frame on which a controller, a connecting frame, a collection hood, and a pretreatment mechanism, an adsorption mechanism, a drying mechanism, and a temperature control mechanism are respectively connected to the controller.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 5 As shown, this application provides an auxiliary device for green and environmentally friendly printing of cardboard boxes, comprising:

[0027] The auxiliary mechanism 100 includes a frame 10, on which a controller 11, a connecting frame 12, a collection hood 13, and a pretreatment mechanism 20, an adsorption mechanism 30, a drying mechanism 40, and a temperature control mechanism 50 are respectively connected to the controller. The pretreatment mechanism 20 and the adsorption mechanism 30 are arranged at intervals in the left-right direction, the collection hood 13 is arranged at intervals in the up-down direction with the pretreatment mechanism 20 and the adsorption mechanism 30, the drying mechanism 40 is located at the end of the connecting frame 12, the upper end of the pretreatment mechanism 20 is provided with a vacuum pump 24, and the input end and the output end of the vacuum pump 24 are respectively connected to the collection hood 13 and the pretreatment mechanism 20. The pretreatment mechanism 20 and the adsorption mechanism 30 are connected by a pipe, and the front side of the pretreatment mechanism 20 is connected to one side of the drying mechanism 40 by a pipe.

[0028] After adopting the above technical solution, the waste gas generated by the printing machine is collected by the collection hood 13 and transported to the pretreatment mechanism 20 for pretreatment. The pretreated waste gas is then treated by the adsorption mechanism 30. The treated clean air enters the heat exchange plate 42 to exchange heat with the untreated waste gas, thereby increasing the temperature of the clean air. On the one hand, this can reduce the temperature of the untreated air and prevent the adsorption effect of the adsorption mechanism 30 from being reduced due to excessive temperature. On the other hand, it heats the clean air. The heated air enters the air distribution pipe 41 and is blown onto the printed cartons to dry them. The heat exchange method reduces the power consumption.

[0029] It should be noted that the exhaust pump 24 draws the exhaust gas generated by the printing press through the collection hood 13 into the pretreatment mechanism 20. The exhaust gas entering the pretreatment mechanism 20 first contacts the heat exchange plate 42 for heat exchange and cooling. After cooling, the exhaust gas passes through the filter plate 22 to filter particles and ink. The pre-filtered exhaust gas then enters the adsorption mechanism 30, where the activated carbon adsorption plate group 32 adsorbs harmful substances from the exhaust gas. The clean air that has adsorbed harmful substances enters the air passage 43 inside the heat exchange plate 42 through a hose. Because the heat exchange plate 42 contacts the untreated exhaust gas for heat exchange, the temperature of the clean air in the air passage 43 rises. The heated clean air... Air enters the air distribution pipe 41 through a flexible hose, and then is blown onto the printed cardboard box through the electric nozzle 44 at the bottom of the air distribution pipe 41 to dry the cardboard box. The temperature sensor 53 inside the air distribution pipe 41 monitors the temperature of the air entering the air distribution pipe 41. When the air temperature is too high, the angle of the heat exchange plate 42 can be changed by driving the cylinder 51 to reduce the area of ​​direct contact between the heat exchange plate 42 and the exhaust gas, thereby lowering the temperature of the clean air after heat exchange. When the air temperature is too low, the clean air after heat exchange can be further heated by the operation of the electric heating iron 52. On the one hand, only a low power consumption is required to reach the required temperature, and on the other hand, the drying temperature can be precisely controlled.

[0030] In an optional embodiment, the filter plate 22 is inclined, and a collection drawer 23 is slidably connected to the lower left side of the pretreatment box 21. When the exhaust gas comes into contact with the filter plate 22, the trapped impurities and ink can fall along the outer wall of the filter plate 22 into the inside of the collection drawer 23. The ink can be uniformly processed by taking out the collection drawer 23.

[0031] In an optional embodiment, the adsorption mechanism 30 includes an adsorption box 31 fixedly installed on the upper right side of the frame 10. An activated carbon adsorption plate group 32 is fixedly installed in the center of the adsorption box 31. After the waste gas enters the adsorption box 31, the harmful substances in the waste gas are adsorbed by the activated carbon adsorption plate group 32.

[0032] In an optional embodiment, the drying mechanism 40 includes an air distribution pipe 41 fixedly installed at the end of the connecting frame 12 and a heat exchange plate 42 hinged to the upper wall of one side of the pretreatment box 21. The heat exchange plate 42 is provided with an air passage 43. One end of the air passage 43 is fixedly connected to the upper right wall of the adsorption mechanism 30 through a hose, and the other end is fixedly connected to the upper wall of the air distribution pipe 41 through a hose. Multiple electric nozzles 44 are fixedly installed at the bottom of the air distribution pipe 41. Clean air that has adsorbed harmful substances enters the air passage 43 inside the heat exchange plate 42 through the hose. Since the heat exchange plate 42 contacts and exchanges heat with the untreated waste gas, the temperature of the clean air in the air passage 43 rises. The heated clean air enters the air distribution pipe 41 through the hose and is then blown onto the printed cardboard box through the electric nozzles 44 at the bottom of the air distribution pipe 41 to dry the cardboard box. The clean air is heated by heat exchange, which reduces the power consumption.

[0033] In an optional implementation, the air duct 43 has a serpentine coil structure to improve heat exchange efficiency.

[0034] In an optional embodiment, the temperature control mechanism 50 includes a cylinder 51 hinged to the upper left wall of the pretreatment box 21, an electric heating iron 52 fixedly installed inside the air distribution pipe 41, and a temperature sensor 53. The output shaft end of the cylinder 51 is hinged to the outer wall of one side of the heat exchange plate 42. When the air temperature is too high, the angle of the heat exchange plate 42 can be changed by driving the cylinder 51 to reduce the area of ​​direct contact between the heat exchange plate 42 and the exhaust gas, thereby reducing the temperature of the clean air after heat exchange. When the air temperature is too low, the clean air after heat exchange can be further heated by the operation of the electric heating iron 52. On the one hand, only a low amount of electrical energy is needed to reach the required temperature, and on the other hand, the drying temperature can be precisely controlled.

[0035] In an optional embodiment, the controller 11 is provided with control buttons and a display screen on the outside, and the controller 11 is provided with a control circuit board and a battery inside. The controller 11 controls the start and stop of the pretreatment mechanism 20, the adsorption mechanism 30, the drying mechanism 40 and the temperature control mechanism 50 to perform automatic waste gas treatment and carton drying.
