Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a printing press drying device equipped with hot air circulation. Background Technology

[0002] A printing press is a mechanical device that uses a printing plate or other carrier to transfer graphic information in the form of ink onto the surface of a substrate through physical or chemical methods. A hot air circulating drying device uses a fan to circulate heated air into a drying chamber. The convection of the hot air transfers heat to the ink on the substrate, accelerating solvent evaporation and achieving drying. For example, in prior art 1 (Chinese patent application number CN202323346648.8, application date 2023-12-08), a printing press with a high-speed hot air drying device blows air after the fan is started. Airflow enters the heating chamber through the exhaust duct. After the heating wire is activated, it heats the airflow to form hot air. The hot air blows downward from the exhaust port. The tilting plate corresponds vertically to the exhaust port. The support plate supports the support rod. There are three support rods to make the tilting plate more stable. When the hot air blows downward, the tilting plate buffers the airflow, reduces the wind force, and prevents the airflow from blowing directly onto the printed matter, which would cause ink to spread and smudge. At the same time, when the tilting plate comes into contact with the hot air, the heating plate is activated and heats up, which heats the airflow again, thereby improving the drying efficiency of the ink and avoiding affecting the printing effect.

[0003] While existing technologies can achieve rapid drying of printed parts, the hot air blowing method in the drying device can only dry the printed parts in the same location. However, this single drying method has a very limited effect and a long drying time, making it impractical. Therefore, a printing press drying device with hot air circulation has been proposed to effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a printing press drying device with hot air circulation, in order to solve the problem mentioned in the background art that the current hot air blowing method on the market can only dry printed parts in the same position. However, this single drying method has a very limited effect and a long drying time, resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing press drying device with hot air circulation, comprising a printing press body and a drying chamber disposed above the printing press body for drying treatment, wherein a guide plate is installed on the outer side of the drying chamber, a conveyor belt for conveying printed parts is disposed inside the drying chamber, a return air duct is installed above the drying chamber, a hot air blower is installed above the drying chamber, and the hot air blower is connected to two hot air outlet plates through pipes, and the two hot air outlet plates are installed below the mounting base.

[0006] Preferably, the drying oven is provided with a drive assembly, which includes a drive motor, and the drive motor is installed on the top inner side wall of the drying oven. The output end of the drive motor is connected to a rotating shaft, and the rotating shaft is rotatably installed inside the mounting frame.

[0007] Preferably, a slide rod is slidably mounted on the lower part of the mounting bracket, and mounting seats are fixedly mounted on both ends of the slide rod, and a hot air outlet plate is rotatably mounted on the lower part of the two mounting seats.

[0008] Preferably, a transmission component is installed on the outer side of the slide rod, and a transmission shaft is slidably installed above the transmission component, and a rotating shaft is connected above the transmission shaft via a crank.

[0009] Preferably, a second magnet is installed on the upper surface of the two hot air outlet plates, and the two second magnets have the same structure, and a first magnet is located above the two second magnets.

[0010] Preferably, the two first magnets are installed below the mounting plates, and the two mounting plates are symmetrically arranged about the vertical center line of the drying oven, and the first magnets and the second magnets have the same magnetic poles.

[0011] Preferably, the output ends of the two hot air outlet discs are connected to one end of a torsion spring, and the two torsion springs have the same structure, and the other end of the two torsion springs is connected to the inner sidewall of the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) The printing machine drying device with hot air circulation is used to process the printing of printed parts. After printing, the printed parts are conveyed to the guide plate by the conveyor belt for unloading. At this time, the hot air blower is started to deliver the generated hot air to the two hot air outlet plates through the pipeline for hot air blowing and drying. The drying efficiency of the printed parts can be improved by using the two hot air outlet plates.

[0014] (2) The printing press drying device with hot air circulation starts the drive motor to drive the rotating shaft to rotate inside the mounting frame during the drying process of the printing press body. At this time, the rotating shaft will drive the transmission shaft to move back and forth on the outer side of the transmission component through the crank. Then the transmission component that moves in position will drive the slide rod to move back and forth under the mounting frame. At this time, the mounting seats installed at both ends of the slide rod can simultaneously drive the hot air outlet plate to move back and forth on the left and right, thereby expanding the air jet range of the two hot air outlet plates and improving the drying efficiency of the drying device for the printed parts.

[0015] (3) The printing press drying device with hot air circulation, when the slide rod drives the two hot air outlet plates set below the two mounting seats to move, the second magnet set above the two hot air outlet plates will drive the two hot air outlet plates to swing in position through the principle of magnetic repulsion between like poles of the first magnet set below the two mounting plates, thereby expanding the air jet range of the two hot air outlet plates and making it more practical.

[0016] (4) The printing press drying device with hot air circulation, after the first magnet and the second magnet are far apart, the torsion spring will use its own elastic force to elastically reset the position of the hot air outlet plate after the squeezing and swinging, so as to facilitate the repeated swinging drying process in the later stage.

[0024] 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.

[0025] This utility model provides the following technical solution: a printing press drying device equipped with hot air circulation.

[0026] Example 1: To address the problem that existing hot air blowing methods can only dry printed parts at the same location, resulting in limited effectiveness, long drying times, and poor practicality, this invention discloses: a printing press body 1, and a drying chamber 2 positioned above the printing press body 1 for drying. The outer side of the drying chamber 2 is equipped with a guide plate 3, and the interior of the drying chamber 2 is equipped with a conveyor belt 5 for transporting printed parts. A return air duct is installed above the drying chamber 2, and a hot air blower 4 is installed above the drying chamber 2. The hot air blower 4 is connected to two hot air outlet plates 6 via pipes, and the two hot air outlet plates 6 are installed below the mounting base 16. During the printing process, after printing, the printed parts are conveyed to the guide plate 3 via the conveyor belt 5 for unloading. At this time, the hot air blower 4 is activated, and the generated hot air is delivered through pipes to the two hot air outlet plates 6 for hot air drying. Figure 1 and Figure 2 As shown.

[0027] The drying oven 2 is equipped with a drive assembly, which includes a drive motor 8. The drive motor 8 is mounted on the inner top wall of the drying oven 2, and the output end of the drive motor 8 is connected to a rotating shaft 9. The rotating shaft 9 is rotatably mounted inside a mounting bracket 7. A slide rod 13 is slidably mounted below the mounting bracket 7, and mounting seats 16 are fixedly mounted at both ends of the slide rod 13. A hot air outlet plate 6 is rotatably mounted below the two mounting seats 16. A transmission component 12 is mounted on the outer side of the slide rod 13, and a transmission shaft 11 is slidably mounted above the transmission component 12. The transmission shaft 11 is connected to a drive mechanism. Crank 10 is connected to shaft 9. When drive motor 8 is started, shaft 9 rotates inside mounting bracket 7. This rotating shaft 9, via crank 10, drives transmission shaft 11 to reciprocate left and right on the outer side of transmission component 12. The reciprocating transmission component 12 then drives slide rod 13 to reciprocate below mounting bracket 7. Simultaneously, the mounting seats 16 at both ends of slide rod 13 drive hot air outlet discs 6 to reciprocate left and right, thereby expanding the airflow range of the two hot air outlet discs 6 and improving the drying efficiency of the drying device for the printed parts. Figure 3 and Figure 4 As shown.

[0028] Example 2 differs from Example 1 in that the blowing range of the two hot air outlet plates 6 can be expanded by setting a driving component, thereby improving the drying efficiency of the printed parts and shortening the drying time of the printing press. The following is disclosed:

[0029] Two second magnets 17 are mounted on the upper surfaces of the two hot air outlet plates 6. The two second magnets 17 have identical structures, and a first magnet 15 is positioned above each of the two second magnets 17. The two first magnets 15 are mounted below the mounting plates 14, which are symmetrically arranged about the vertical center line of the drying chamber 2. The first magnets 15 and second magnets 17 have the same magnetic poles. When the slide rod 13 moves the two hot air outlet plates 6 located below the two mounting bases 16, the second magnets 17 above the two hot air outlet plates 6 and the first magnets 15 below the two mounting plates 14 repel each other through the principle of magnetic repulsion, causing the two hot air outlet plates 6 to swing in position. This expands the air jet range of the two hot air outlet plates 6. Figure 4 and Figure 5 As shown.

[0030] The output ends of the two hot air outlet plates 6 are connected to one end of a torsion spring 18, and the two torsion springs 18 have the same structure. The other end of the two torsion springs 18 is connected to the inner wall of the mounting base 16. After the first magnet 15 and the second magnet 17 move away from each other, the torsion spring 18 will use its own elastic force to elastically reset the position of the hot air outlet plates 6 after the squeezing and swinging, so as to facilitate the subsequent repeated swinging drying process. Figure 4 and Figure 6 As shown.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
