[0002] With the development of the economy, people's environmental awareness is increasing. At present, environmentally friendly water-based inks are mostly used in the printing and packaging industry. Since the solvent in water-based inks is water, it is difficult to evaporate compared to traditional solvents, the drying speed is slow, and the work efficiency is low. If the drying speed is too fast, the water solvent in the ink evaporates too quickly, which can easily cause the printed graphics on the packaging box to crack.

[0003] In the related art, in order to dry the printed matter, a hot air blower is generally arranged at the exit of the printing press to dry the ink on the surface of the printed matter. Since the hot air blower is arranged at the exit of the printing press, the temperature at the exit of the printing press is easily affected by the indoor ambient temperature, which easily leads to uneven drying of the ink on the surface of the printed matter, affecting the product quality.

[0014] In a specific possible implementation manner, the height of one of the conveying rollers in the conveying member is smaller than the height of the other conveying roller.

[0015] By adopting the above technical solution, by setting two conveying rollers in a plurality of conveying members at different heights, the paper between the two conveying rollers is tilted, thereby increasing the area of ​​the paper between the two conveying rollers, thereby helping to improve the drying efficiency of the ink on the paper surface.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The present application embodiment discloses an ink drying oven mechanism. Figure 1 and Figure 2 The ink drying mechanism comprises a box body 1, in which a primary drying chamber 2, a secondary drying chamber 3, a cooling chamber 4 and a discharge chamber 5 are respectively arranged. A feeding port is arranged on the wall of the primary drying chamber 2 of the box body 1 to facilitate paper feeding. An inlet communicating with the primary drying chamber 2 is arranged on the wall of the cooling chamber 4, and an outlet communicating with the secondary drying chamber 3 is arranged on the wall of the cooling chamber 4. The primary drying chamber 2, the secondary drying chamber 3, the cooling chamber 4 and the discharge chamber 5 are interconnected.

[0038] A drying component 6 for drying the ink on paper is provided on the walls of the primary drying chamber 2 and the secondary drying chamber 3, a cooling component 7 for cooling the ink on paper is provided in the cooling chamber 4, and a transmission and dispersion component 8 for dispersing paper is provided on the walls of the primary drying chamber 2 and the secondary drying chamber 3.

[0039] During operation, the paper is fed into the primary drying chamber 2 in the box 1, and the paper is dispersed and transported by the transmission and dispersion component 8. During the dispersion and transportation of the paper, the drying component 6 is used to dry the paper, and the transmission and dispersion component 8 in the primary drying chamber 2 is used to transport the paper through the cooling chamber 4 and into the secondary drying chamber 3. Since the temperature in the cooling chamber 4 is lower than the temperature in the primary drying chamber 2, when the paper enters the cooling chamber 4, the cooling component 7 is used to cool the ink on the paper, which is helpful for the solidification of the ink.

[0040] Finally, the paper enters the secondary drying chamber 3 after passing through the cooling chamber 4, and the paper is dispersed by the transmission and dispersion component 8 in the secondary drying chamber 3, and the paper ink is secondary dried by the drying component 6, which improves the drying efficiency of the paper ink. Finally, the transmission and dispersion component 8 in the secondary drying chamber 3 is used to send the secondary dried paper into the discharge chamber 5, so that the paper can be collected and discharged. When drying the paper as described above, dispersing the paper helps to dry the ink on the surface of the paper evenly, and after the initial drying of the paper, the secondary drying is performed after cooling the paper, which helps to improve the drying effect of the paper.

[0041] Reference Figure 2 and Figure 3 The drying component 6 includes a hot air blower 61 and an electric heating wire, which is arranged on the hot air blower 61. The side walls of the box body 1 located in the primary drying chamber 2 and the secondary drying chamber 3 are both provided with grooves 62. The hot air blower 61 is arranged on the groove wall of the groove 62. The side wall of the box body 1 is fixedly installed with a protective net 63 for covering the groove 62. The protective net 63 is provided with a plurality of air outlet holes 64; the hot air blower 61 is started, and the electric heating wire is connected to the power supply at the same time, so that the hot air blower 61 blows hot air into the primary drying chamber 2 or the secondary drying chamber 3 to dry the ink on the surface of the paper.

[0042] Reference Figure 4There are two groups of transmission and dispersion components 8, one of which is arranged in the primary drying chamber 2, and the other is arranged in the secondary drying chamber 3. One group of transmission and dispersion components 8 includes a plurality of transmission parts, and the transmission parts include two oppositely arranged transmission rollers 81. The transmission rollers 81 are rotatably connected to the inner wall of the box body 1. The side wall of the box body 1 is provided with a power source for driving the transmission rollers 81 to rotate. In this embodiment, the power source can be a motor.

[0043] The paper is wound around the conveying rollers 81 of several conveying members. When the conveying rollers 81 are driven to rotate by a power source, the paper is dispersed, so that the paper in the primary drying chamber 2 can be conveyed to the cooling chamber 4, and the paper in the secondary drying chamber 3 can be conveyed to the discharge chamber 5. In this embodiment, by winding the paper around the conveying rollers 81 of the conveying members, it helps to extend the time that the paper is in the primary drying chamber 2 and the secondary drying chamber 3, thereby improving the drying effect of the ink on the surface of the paper, so that the ink on the surface of the paper can be evenly dried.

[0044] In this embodiment, the central axes of the two conveying rollers 81 in the conveying member are not collinear, so that the paper between the two conveying rollers 81 is in an inclined state. Compared with the paper in a horizontal state, it helps to increase the drying area of ​​the paper between the two conveying rollers 81, thereby improving the drying efficiency of the ink on the surface of the paper.

[0045] Reference Figure 4 and Figure 5 The cooling assembly 7 includes a first cooling fan 71 and a plurality of second cooling fans 73. An adjusting motor 72 is provided on the wall of the cooling chamber 4. The driving shaft of the adjusting motor 72 is connected to the first cooling fan 71 through a bracket. The air outlet of the first cooling fan 71 is arranged opposite to the ink surface of the paper. The plurality of second cooling fans 73 are embedded in the wall of the cooling chamber 4. The air outlets of the second cooling fans 73 face the side of the paper. When the adjusting motor 72 is started, the adjusting motor 72 drives the first cooling fan 71 to rotate, which helps to increase the cooling area of ​​the ink on the paper surface. At the same time, in cooperation with the second cooling fan 73, the cooling speed and cooling effect of the ink on the paper surface are further improved.

[0046] Reference Figure 2 and Figure 5 A detection port 9 corresponding to the cooling chamber 4 is provided on the side wall of the box body 1 located at the observation door 14. The setting of the detection port 9 enables the cooling chamber 4 to communicate with the air outside the box body 1, which helps to improve the cooling effect on the paper.

[0047] A guide is provided on the side wall of the cooling chamber 4 near the inlet, and the guide includes two guide rollers 10 arranged opposite to each other. The two guide rollers 10 are both rotatably connected to the wall of the cooling chamber 4, and a guide channel for the paper to pass through is reserved between the two guide rollers 10. Two opposite discharge rollers 11 are rotatably provided on the wall of the cooling chamber 4 near the outlet, and the peripheral wall of one of the discharge rollers 11 is used to abut against the side wall of the paper facing away from the ink surface, and the peripheral wall of the other discharge roller 11 is used to abut against the side wall of the paper facing the ink surface.

[0048] A limiting member is provided on the wall of the cooling chamber 4 and between the guide member and the discharge roller 11. The limiting member includes two opposing limiting rollers 12. Both limiting rollers 12 are rotatably provided on the wall of the cooling chamber 4. A limiting channel for paper to pass through is reserved between the two limiting rollers 12. The provision of the guide roller 10, the discharge roller 11 and the limiting roller 12 helps to prolong the time that the paper is in the cooling chamber 4, so as to improve the cooling effect on the paper.

[0049] Reference Figure 5 Since the friction between the paper and the guide roller 10, the discharge roller 11 and the limit roller 12 generates heat, in order to further enhance the cooling effect on the paper, the peripheral walls of the guide roller 10, the discharge roller 11 and the limit roller 12 are embedded with cooling fins 13; the setting of the cooling fins 13 reduces the temperature of the side walls of the guide roller 10, the discharge roller 11 and the limit roller 12, so that the paper can be dissipated and cooled when the paper is conveyed.

[0050] The implementation principle of an ink drying oven mechanism in an embodiment of the present application is as follows: paper is fed into the primary drying chamber 2 in the box body 1, and a power source is used to drive the conveying roller 81 to rotate, so that several conveying rollers 81 in the primary drying chamber 2 and the secondary drying chamber 3 disperse and convey the paper, and in the process of dispersing and conveying the paper, the hot air blower 61 is used to dry the paper, and the conveying roller 81 in the primary drying chamber 2 is used to convey the paper through the cooling chamber 4 and into the secondary drying chamber 3. Since the temperature in the cooling chamber 4 is lower than the temperature in the primary drying chamber 2, when the paper enters the cooling chamber 4, the first cold air blower 71 and the second cold air blower 73 are used to cool the ink on the surface of the paper so that the ink on the surface of the paper is solidified.

[0051] Finally, the paper enters the secondary drying chamber 3 after passing through the cooling chamber 4, and is dispersed by using several conveying rollers 81 in the secondary drying chamber 3. At the same time, the hot air blower 61 is used to perform secondary drying on the paper ink, thereby improving the drying efficiency of the paper ink. Finally, the paper that has undergone secondary drying is sent to the discharge chamber 5 by using several conveying rollers 81 in the secondary drying chamber 3 so that the paper can be collected and discharged.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
