An ink printing drying and deodorizing device

Abstract

This utility model relates to the field of ink printing equipment technology, specifically disclosing a drying and deodorizing device for ink printing. It includes a base, and deodorizing components are provided on both the inner and outer sides of a drying chamber. The deodorizing components include a gas supply pipe located on the left side inside the drying chamber, and a hollow cavity opened on the upper right side inside the drying chamber. A water storage tank is fixedly connected to the upper side of the hollow cavity. The upper half of the gas supply pipe passes through the lower sides of both the hollow cavity and the water storage tank from bottom to top. A processing chamber is opened on the upper side of the drying chamber. The gas is cooled by the water storage tank, and then harmful substances inside the gas are absorbed by activated carbon bags. Because the gas carrying harmful substances is further cooled after being drawn away by the gas supply pipe, the harmful substances are quickly adsorbed by the activated carbon bags during the process of passing through them. This avoids the harmful gas affecting the adsorption efficiency of the activated carbon bags due to high temperatures, thus ensuring the deodorization efficiency of the workpiece.

Description

Technical Field

[0001] This utility model relates to the field of ink printing equipment technology, and in particular to a drying and deodorizing device for ink printing. Background Technology

[0002] Ink is a homogeneous mixture composed of colored substances (such as pigments and dyes), binders, fillers, and additives; it can be printed and dries on the printed surface; it is a colored paste-like adhesive with a certain degree of fluidity. Therefore, color (hue), body (thickness, fluidity, and other rheological properties), and drying properties are the three most important properties of ink. There are many types of ink with different physical properties. Some are very thick and viscous, while others are quite thin. Some use vegetable oil as a binder, while others use resin and solvents or water as binders. These are all determined by the printing object, i.e., the substrate, the printing method, the type of printing plate, and the drying method.

[0003] Printing ink is a colorant used in printing, composed of pigments, binders, and additives. It has a wide range of applications, primarily in the printing of books, packaging, and architectural decoration. Common organic solvents used in printing inks include ethanol, isopropanol, butanol, propanol, methyl ethyl ketone (MEK), ethyl acetate, butyl acetate, toluene, and xylene. Although most of these organic solvents disappear after drying, residual odors can still cause discomfort. Furthermore, printing uses large amounts of benzene-containing diluents, which are toxic and have a strong, irritating odor, easily polluting the air. Therefore, removing unpleasant odors from the ink system is particularly important.

[0004] In existing technologies, since the drying process is the main source of VOCs emissions, traditional hot air drying will release pollutants such as ethyl acetate in an unorganized manner. In small-scale production, low-concentration VOCs will be adsorbed by activated carbon or zeolite. However, after hot air drying, the airflow temperature itself is high. If it is directly adsorbed by activated carbon or zeolite, it will affect the effectiveness of activated carbon or zeolite. Summary of the Invention

[0005] The purpose of this invention is to provide a drying and deodorizing device for ink printing, which can cool down the gas carrying harmful substances before adsorbing it through an activated carbon bag, preventing high temperature from affecting the adsorption efficiency of the activated carbon bag for harmful substances, thereby solving the problems mentioned in the background art.

[0012] Preferably, the drying oven is provided with a locking component on both its inner and outer sides, and the locking component includes a material basket that is slidably connected to the upper side of the base.

[0013] Preferably, the left and right side walls inside the drying chamber are provided with downward-reaching limiting grooves. Limiting plates are slidably connected inside the limiting grooves.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A drying and deodorizing device for ink printing includes a base 1 and a drying chamber 11 disposed on the upper side of the base 1. A heating element 12 is disposed on the upper side of the interior of the drying chamber 11, an air inlet pipe 13 is disposed on the upper side of the interior of the drying chamber 11, a controller 14 is disposed on the front side of the drying chamber 11, and a deodorizing component 2 is disposed on both the inner and outer sides of the drying chamber 11. The deodorizing component 2 includes an air supply pipe 21 disposed on the left side of the interior of the drying chamber 11.

[0028] A hollow cavity 22 is provided on the upper right side of the interior of the drying oven 11. A water storage tank 23 is fixedly connected to the upper side of the interior of the hollow cavity 22. The upper half of the air supply pipe 21 passes through the lower side of the interior of the hollow cavity 22 and the water storage tank 23 from bottom to top. A processing chamber 24 is provided on the upper side of the drying oven 11. The top end of the air supply pipe 21 extends into the interior of the processing chamber 24. A storage frame 25 is inserted into the interior of the processing chamber 24. A pull rod 26 is fixedly connected to the upper side of the storage frame 25. Hollow mesh 27 is fixedly connected to both the left and right sides of the storage frame 25. Activated carbon bags 28 are placed inside the storage frame 25. An air outlet pipe 29 is provided on the right side of the drying oven 11. The left end of the air outlet pipe 29 extends into the interior of the processing chamber 24.

[0029] The air inlet pipe 13 is L-shaped. The right end of the air inlet pipe 13 is connected to the external air supply device, the lower end of the air inlet pipe 13 extends to the upper side of the heating element 12, and the other end of the air outlet pipe 29 is connected to the external air extraction device.

[0030] The lower half of the gas supply pipe 21 is C-shaped, and the upper half of the gas supply pipe 21 is threaded. The inner cavity of the drying chamber 11 is connected to the processing chamber 24 through the gas supply pipe 21.

[0031] The water storage tank 23 surrounds the upper half of the threaded part of the gas transmission pipe 21. A water inlet pipe 231 is provided at the upper right rear of the water storage tank 23, and a water outlet pipe 232 is provided at the left front of the output end of the water storage tank 23. The end of the water inlet pipe 231 away from the water storage tank 23 is connected to an external water supply device, and the end of the water outlet pipe 232 away from the water storage tank 23 is connected to an external pumping device.

[0032] The shape of the storage box 25 is adapted to the shape of the processing chamber 24, the pull rod 26 is T-shaped, and the air supply pipe 21 is connected to the air outlet pipe 29 through the processing chamber 24.

[0033] By adopting the above technical solution, the heating element 12 is preheated, and then the air inlet pipe 13 blows gas toward the heating element 12 through an external air supply device. Next, the workpiece is sent into the drying chamber 11 through the base 1. The gas, after passing through the heating element 12, carries the heat to the outside of the workpiece for drying. Then, an external air extraction device extracts the gas entering the air supply pipe 21 through the air outlet pipe 29, causing the air supply pipe 21 to extract harmful gases from inside the drying chamber 11. When harmful gases enter the threaded part of the air supply pipe 21, if the harmful gases reach the position of the hollow cavity 22 in the air supply pipe 21, the heat in the harmful gases dissipates, causing the heat to gradually accumulate in the hollow cavity 22. Since the hollow cavity 22 is close to the inner cavity of the drying chamber 11, the heat slowly decreases and enters the inner cavity of the drying chamber 11. When the harmful gases enter the position of the water storage tank 23, because the water storage chamber is connected to the water inlet pipe 231... The system continuously supplies water to the external water supply device, but the water tank 23 is not connected to the gas supply pipe 21. This allows the heat of the harmful gas to be gradually absorbed by the water source and cooled down. The water source, after absorbing the heat, is discharged through the water outlet pipe 232 in conjunction with the external water pumping device. At the same time, the cooled harmful gas enters the interior of the processing chamber 24 through the gas supply pipe 21, and then enters the interior of the storage frame 25 through the hollow mesh 27 on the left side. After being absorbed by the activated carbon pack 28, the harmful substances are discharged through the hollow mesh 27 on the right side, and finally discharged from the drying oven 11 through the external air extraction device in conjunction with the air outlet pipe 29. Since the gas carrying harmful substances is further cooled after being drawn away by the gas supply pipe 21, the harmful substances can be quickly adsorbed by the activated carbon pack 28 during the process of passing through the activated carbon pack 28. This avoids the harmful gas affecting the adsorption efficiency of the activated carbon pack 28 for harmful substances due to high temperature, thereby ensuring the deodorization efficiency of the workpiece.

[0034] Specifically, such as Figures 2 to 4 As shown, the drying oven 11 is provided with locking components 3 on both the inner and outer sides. The locking components 3 include a material basket 31 that is slidably connected to the upper side of the base 1.

[0035] The left and right side walls inside the drying oven 11 are both downwardly extending through a limiting groove 32. A limiting plate 33 is slidably connected inside the limiting groove 32. A pressure spring 34 is fixedly connected to the upper side of the limiting plate 33 in a longitudinal linear array. The other end of the pressure spring 34 is fixedly connected to the upper side inside the limiting groove 32. Guide grooves 35 are provided on both the left and right sides of the drying oven 11. A guide plate 36 is fixedly connected to the side of the left and right limiting plates 33 that are far apart. The guide groove 35 is connected to the limiting groove 32. The guide plate 36 is slidably connected inside the guide groove 35. The opposite surfaces of the left and right limiting plates 33 are provided with inclined surfaces. The inclined surfaces of the opposite surfaces of the left and right limiting plates 33 are in sliding and pressing contact with the left and right sides of the material basket 31, respectively.

[0036] The drying box 11 surrounds the outer surface of the material basket 31. The shape of the limiting groove 32 is adapted to the shape of the limiting plate 33, and the shape of the guide groove 35 is adapted to the shape of the guide plate 36. The highest point of the inclined surface of the limiting plate 33 is lower than the upper horizontal surface of the material basket 31.

[0037] By adopting the above technical solution, after the workpiece is dried, since the limiting plate 33 is fixed to the guide plate 36, the guide plate 36 inside the guide groove 35 is slightly lifted upwards. As the inclined surface on the other side of the limiting plate 33 becomes level with the upper side of the basket 31, the basket 31 can be pulled so that the side of the basket 31 contacts the inclined surface of the limiting plate 33. At this time, the basket 31 pushes the inclined surface of the limiting plate 33, and the limiting plate 33 retracts into the limiting groove 32 and squeezes the pressure spring 34 inside the limiting groove 32. When the basket 31 is separated from the limiting plate 33, the pressure spring 34 pushes the limiting plate 33 again, so that the limiting plate 33 returns to its original position. Since the limiting plate 33 can restrict the basket 31 when it is not lifted upwards, and the basket 31 can be quickly removed from the inside of the drying box 11 by slightly lifting the guide plate 36 on either side, the drying and deodorization efficiency of the workpiece is guaranteed.

[0038] Working principle: Harmful gases enter the gas supply pipe 21. When the harmful gases enter the threaded part of the gas supply pipe 21, if the harmful gases reach the hollow cavity 22 of the gas supply pipe 21, the heat in the harmful gases dissipates, causing heat to gradually accumulate in the hollow cavity 22. If the harmful gases enter the water storage tank 23, the heat of the harmful gases is gradually absorbed by the water inside the water storage tank 23, thus achieving cooling. The cooled harmful gases then enter the processing chamber 24 through the gas supply pipe 21 and enter the storage frame 25 through the perforated mesh 27 on the left side of the storage frame 25. After being absorbed by the activated carbon pack 28, the harmful gases... The material is discharged from the right-side perforated mesh 27 and finally discharged from the drying chamber 11 through the external exhaust device and the exhaust pipe 29. After the workpiece is dried, the guide plate 36 inside the guide groove 35 is slightly raised. At this time, the material basket 31 can be pulled so that the side of the material basket 31 contacts the inclined surface of the limiting plate 33. At this time, the material basket 31 pushes the inclined surface of the limiting plate 33. The limiting plate 33 retracts into the limiting groove 32 and squeezes the pressure spring 34 inside the limiting groove 32. When the material basket 31 is separated from the limiting plate 33, the pressure spring 34 pushes the limiting plate 33 again, so that the limiting plate 33 returns to its original position.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
