Description

Technical Field

[0001] The present application relates to the technical field of printing machines, and in particular to a drying device for a printing machine. Background Art

[0002] During the printing process, ink or printing ink is printed on paper in a liquid state. In order to ensure the quality and durability of the printed matter, the ink needs to be dried to quickly change from a liquid state to a solid state. After printing, if the ink is not completely dry, the surface of the paper may be very sticky. This will cause the paper to stick together when stacked or wrapped, and may even cause the print to fall off, seriously affecting the quality of the printed matter. Therefore, printing presses are usually equipped with a drying system, such as a hot air dryer or an infrared drying lamp to dry the printed matter;

[0003] Existing printing machine drying devices mostly use hot air circulation or infrared radiation to dry printed materials. Although these technologies can meet the drying needs of printed materials to a certain extent, they still have the following significant disadvantages: first, the drying efficiency is low, which leads to limited printing production efficiency; second, the energy consumption is large, which is not conducive to energy conservation and emission reduction; third, the dried printed materials need to be cooled before they can be stacked to prevent overheating from causing deformation of the printed materials, but the existing technology cannot cool the dried printed materials in time, and the cooling effect using room temperature is slow, so there is a lot of room for improvement.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

A printing mechanism is arranged on the right side of the drying chamber 1, and a winding mechanism is arranged on the left side of the drying chamber 1. One end of the printed advertising paper 5 passes through the three feeding ports 9 and is fixedly connected to the outer surface of the winding roller of the winding mechanism. Under the action of the winding mechanism, the printed advertising paper 5 slowly passes through the drying chamber 1, is first fully dried by the drying mechanism, then cooled by the cooling mechanism, and finally is wound up, so that the whole process of drying, cooling and winding can be completed quickly and efficiently.

[0022] Reference Figure 2 and Figure 3The infrared lamp 8 is fixedly connected to the inner top wall of the drying chamber 1. The infrared lamp 8 can use infrared radiation to directly act on the surface of the advertising paper 5, so that the internal moisture evaporates quickly, which greatly shortens the drying time. Compared with the traditional drying method, infrared drying is more energy-saving and reduces energy consumption. One end of the heating cylinder 11 is fixedly connected to one of the fixed blocks 10, and the other end of the heating cylinder 11 is fixedly passed through another fixed block 10. The two fixed blocks 10 are fixedly connected to the inner bottom wall of the drying chamber 1, which play a role of fixed support for the heating cylinder 11. The roller 12 is sleeved on the outer surface of the heating cylinder 11 and is connected to the heating cylinder 11. Rotating connection, a heating tube 13 is inserted into the heating cylinder 11, one end of the heating tube 13 is fixedly connected to the heating cylinder 11 by multiple bolts 14, the heating tube 13 is manually energized, the heating tube 13 generates heat to heat the air inside the heating cylinder 11, the heating cylinder 11 is heated and then the roller 12 is heated, the bottom of the advertising paper 5 first passes through the roller 12, and drives the roller 12 to rotate, the roller 12 preheats the bottom of the advertising paper 5, and then the advertising paper 5 passes through the bottom of the infrared lamp 8, the infrared lamp 8 performs infrared drying on the top of the advertising paper 5, and can quickly and efficiently dry the advertising paper 5 comprehensively.

[0023] Reference Figure 2 and Figure 4 The cooling mechanism includes two fixed blocks 10, a cooling cylinder 15, a roller 12 and a liquid inlet pipe 16. One end of the cooling cylinder 15 is fixedly connected to one of the fixed blocks 10, and the other end of the cooling cylinder 15 is fixedly penetrated by the other fixed block 10. The two fixed blocks 10 are fixedly connected to the inner bottom wall of the drying chamber 1, and play a role of stable fixed support for the cooling cylinder 15. The roller 12 is sleeved on the outer surface of the cooling cylinder 15 and is rotatably connected to the cooling cylinder 15. The top of the cooling cylinder 15 is connected to the liquid inlet pipe 16. A threaded cap 17 is threadedly connected to one end of the liquid inlet pipe 16. Coolant can be added to the cooling cylinder 15 through the liquid inlet pipe 16. The threaded cap 17 can seal the liquid inlet pipe 16 to prevent the coolant inside the liquid inlet pipe 16 from evaporating. The coolant reduces the temperature of the cooling cylinder 15, and then reduces the temperature of the roller 12. When the dried advertising paper 5 passes through the top of the cooling cylinder 15, it contacts the roller 12, so that the advertising paper 5 can be cooled, which facilitates the winding of the advertising paper 5.

[0024] Reference Figure 1 and Figure 2 A vent is provided at the top of the drying chamber 1, and an axial flow fan 6 is installed in the vent. A large amount of water vapor will be generated during the drying process. The axial flow fan 6 is manually opened to extract the water vapor in the drying chamber 1 out of the drying chamber 1 to prevent the water vapor from liquefying and dripping onto the top of the advertising paper 5, thereby affecting the finished product effect of the advertising paper 5.

[0025] Reference Figure 1The heating cylinder 11 and the cooling cylinder 15 are both made of copper. Copper has a high thermal conductivity, which makes it easy to transfer the hot and low temperatures of the heating cylinder 11 and the cooling cylinder 15 to their respective rollers 12. The roller 12 is made of polystyrene foam. Polystyrene foam has a high thermal conductivity, which makes it easy to continuously transfer the hot and low temperatures of the heating cylinder 11 and the cooling cylinder 15 to the advertising paper 5. The polystyrene foam contacts the advertising paper 5 to increase the friction with the advertising paper 5, thereby allowing the advertising paper 5 to be heated or cooled more fully.

[0026] The implementation principle of a drying device for a printing press in the embodiment of the present application is as follows: by setting a drying mechanism and a cooling mechanism, one end of the printed advertising paper 5 passes through three feed ports 9 and is fixedly connected to the outer surface of the winding roller of the winding mechanism. The printed advertising paper 5 slowly passes through the drying chamber 1 under the action of the winding mechanism. The heating tube 13 is powered manually, and the heating tube 13 generates heat to heat the air inside the heating cylinder 11, so that the heating cylinder 11 is heated and the roller 12 is heated. The bottom of the advertising paper 5 first passes through the roller 12 and drives the roller 12 to rotate. The roller 12 cools the advertising paper 5 to the bottom of the advertising paper 5. The bottom of the advertisement paper 5 is preheated, and then the advertisement paper 5 passes through the bottom of the infrared lamp 8, and the infrared lamp 8 performs infrared drying on the top of the advertisement paper 5, which can quickly and comprehensively and efficiently dry the advertisement paper 5. The axial flow fan 6 is manually turned on to extract the water vapor in the drying chamber 1 out of the drying chamber 1 to prevent the water vapor from liquefying and dripping to the top of the advertisement paper 5, affecting the finished product effect of the advertisement paper 5. When the dried advertisement paper 5 passes through the top of the cooling cylinder 15, it contacts the roller 12, which can cool the advertisement paper 5, thereby facilitating the winding of the advertisement paper 5, and has the effects of comprehensive and efficient drying and timely cooling.
