Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and more specifically, it relates to a novel cooling device for digital printing machines. Background Technology

[0002] In existing technologies, existing cooling devices cannot effectively cool the printed paper during use. Digital printing presses generate a lot of heat when operating under high load, especially after the paper passes through the printing device quickly, when its surface temperature is high. If the paper cannot be cooled efficiently in time, it may cause the paper to deform, curl, or degrade in performance, seriously affecting the printing quality and the stability of subsequent processes.

[0003] Secondly, existing cooling devices cannot quickly break free from the fixed flow rate in actual use. Current devices are usually designed according to fixed operating parameters. For example, the flow rate of cooling air or coolant is often limited to a fixed value or a small adjustment range. Although this fixed rate design can ensure the basic operation of the device, it lacks flexibility in practical applications.

[0004] In addition, existing cooling devices cannot flexibly adjust the outflow rate of gas during use. The gas flow rate plays a crucial role in the cooling effect. However, the gas output rate of existing equipment is usually designed as a fixed value, which is difficult to dynamically adjust according to actual needs. When a higher gas flow rate is required to quickly remove heat, the existing device cannot meet the requirements. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a novel cooling device for digital printing machines, which has the following beneficial effects:

[0018] 1. The printing assembly uses a combination of an adsorption plate and an adsorption tube. The adsorption force generated by the fan firmly fixes the paper to be printed on the adsorption plate, preventing the paper from sliding or flying up during the printing process. This improves the stability and accuracy of the printing. The electric moving frame can slide along the fixed frame to accurately move the paper on the adsorption plate to the bottom of the printing frame, realizing automated positioning and conveying, and improving the overall printing efficiency.

[0019] 2. The control component, through the linkage design of the regulating tube, rotating tube, and locking plate, enables flexible adjustment of the speed and direction of the cooling airflow. This allows for precise control of the cooling intensity according to the paper's needs, preventing the paper from being affected by overcooling or undercooling. The sliding design of the pull ring and pull rod makes operation more intuitive and convenient. Adjustment can be completed with simple pulling and rotating actions, eliminating the need for complex mechanical adjustments and lowering the operational threshold.

[0020] 3. The regulating component utilizes the linkage design of threaded rod, threaded block and baffle block. By rotating the rotating tube, the baffle block is pushed to slide in the sliding groove, which realizes precise control of the size of the airflow channel and the airflow rate, thereby meeting different cooling requirements. By flexibly adjusting the wind resistance, energy waste caused by excessively fast or slow airflow can be avoided, thereby improving the energy efficiency ratio of the device and saving energy.

[0031] Please see Figures 1-6 A novel cooling device for a digital printing machine includes a base frame 1. A printing assembly is mounted on the base frame 1. The printing assembly includes a fixed frame 2, an electric moving frame 3, a printing frame 4, an adsorption plate 5, an adsorption tube 6, a fan 7, a circulation pipe 8, and an exhaust pipe 9. The fixed frame 2 is fixedly mounted on the base frame 1. The electric moving frame 3 is slidably connected to the fixed frame 2. The printing frame 4 is mounted on the fixed frame 2. The adsorption plate 5 is mounted on the electric moving frame 3. The adsorption tube 6 is connected to the adsorption plate 5. The fan 7 is connected to the adsorption tube 6. The circulation pipe 8 is mounted on the adsorption plate 5. The exhaust pipe 9 passes through the electric moving frame 3 and is connected to one end of the circulation pipe 8. A control assembly is mounted on the exhaust pipe 9. The control assembly includes an adjusting pipe 10, a rotating pipe 11, and a locking plate 12. The adjusting pipe 10 is mounted on the air inlet pipe 13. The rotating pipe 11 is rotatably connected to the adjusting pipe 10. The locking plate 12 is mounted on the rotating pipe 11.

[0032] The other end of the circulation pipe 8 passes through the electric moving frame 3 and is connected to the air inlet pipe 13.

[0033] A top plate 14 is installed on the top of the base frame 1, and a cooler 15 is installed on the top plate 14. The cooler 15 is connected to the exhaust pipe 9 and the intake pipe 13.

[0034] A pull ring 16 is slidably connected to the adjusting tube 10, and a pull rod 17 is connected to the pull ring 16. A pull block 18 is installed at one end of the pull rod 17, and a tension spring 19 is sleeved on the pull rod 17. One end of the pull rod 17 passes through the adjusting tube 10 and is inserted into the locking plate 12.

[0035] A rotating ring 20 is rotatably connected to the regulating pipe 10. The rotating ring 20 has a rotating groove 21 and a through groove 22. The rotating groove 21 is adapted to the pulling rod 17, and the through groove 22 is adapted to the pulling block 18.

[0036] In this embodiment, during use, the paper to be printed is placed on the adsorption plate 5, and the fan 7 is started, using its output adsorption tube 6 to adsorb the paper placed on the adsorption plate 5, thereby effectively preventing it from flying off. Then, the electric moving frame 3 slides it along the fixed frame 2 to the bottom of the printing frame 4, thus completing the printing process. After printing, if rapid cooling is required, the cooler 15 delivers cold air along the air inlet pipe 13 to the circulation pipe 8 of the electric moving frame 3, thereby completing the cooling process of the printed paper. After the cooling process is completed, and during the cooling process, in order to flexibly adjust the gas flow rate, the pull ring is... 16 slides along the adjusting tube 10, and during this sliding movement, it drives the pulling rod 17 and the pulling block 18 on it to move. During this movement, the tension spring 19 sleeved on the pulling rod 17 is stretched, thereby moving one end of the pulling rod 17 out of the locking plate 12 on the rotating tube 11. After the pulling block 18 passes through the through groove 22 on the rotating ring 20, the rotating ring 20 rotates along the adjusting tube 10. After the pulling block 18 moves away from the through groove 22, the rotating ring 20 rotates again, thereby releasing the pulling ring 16. Under the action of the elastic potential energy of the tension spring 19, the pulling block 18 on the pulling rod 17 is locked onto the rotating ring 20.

[0037] Please see Figure 4-5 As a novel cooling device for digital printing presses, an adjustment component is provided on the rotating tube 11. The adjustment component includes a threaded rod 23, a threaded block 24, and a sliding groove 25. The threaded rod 23 is installed on the rotating tube 11, the threaded block 24 is threadedly connected to the threaded rod 23, and the sliding groove 25 is evenly distributed on the adjustment tube 10.

[0038] A flow-blocking block 26 is slidably connected on the sliding groove 25, and one end of the flow-blocking block 26 abuts against the threaded block 24.

[0039] A spring 27 is provided to connect one end of the flow baffle 26 and the regulating pipe 10, and the body 28 is installed on the base frame 1.

[0040] More specifically, after releasing the fixing of the rotating tube 11, the rotating tube 11 is rotated along the regulating tube 10. During the rotation, the threaded rod 23 on it rotates, which in turn moves the threaded block 24 connected to it. During this movement, the baffle block 26, which abuts against the threaded block 24, slides along the sliding groove 25 on the regulating tube 10. During this sliding movement, the spring 27 between the baffle block 26 and the regulating tube 10 is compressed. This increases the contact area between the air and the baffle block 26 after the air flows through the regulating tube 10, thereby creating a certain wind resistance and reducing the airflow rate. Conversely, the airflow rate increases.

[0041] In summary, during the use or operation of the overall equipment: The paper to be printed is placed on the suction plate 5, and the fan 7 is started, using its output suction pipe 6 to adsorb the paper placed on the suction plate 5, effectively preventing it from flying off. Then, the electric moving frame 3 slides along the fixed frame 2 to the bottom of the printing frame 4, thus completing the printing process. After printing, if rapid cooling is needed, the cooler 15 delivers cold air along the air inlet pipe 13 to the circulation pipe 8 of the electric moving frame 3, thus completing the cooling process of the printed paper. Furthermore, during the cooling process, the gas flow rate can be flexibly adjusted. The pull ring 16 slides along the adjusting tube 10, and during this sliding movement, it drives the pull rod 17 and pull block 18 on it to move. During this movement, the tension spring 19 sleeved on the pull rod 17 is stretched, thereby moving one end of the pull rod 17 out of the locking plate 12 on the rotating tube 11. After the pull block 18 passes through the through groove 22 on the rotating ring 20, the rotating ring 20 rotates along the adjusting tube 10. After the pull block 18 moves away from the through groove 22, the rotating ring 20 rotates again, thereby releasing the pull ring 16. Under the action of the elastic potential energy of the tension spring 19, the pull block 18 on the pull rod 17 is locked onto the rotating ring 20.

[0042] After releasing the fixing of the rotating tube 11, the rotating tube 11 is rotated along the regulating tube 10. During the rotation, the threaded rod 23 on it rotates, which in turn moves the threaded block 24 connected to it. During this movement, the baffle block 26, which is in contact with the threaded block 24, slides along the sliding groove 25 on the regulating tube 10. During this sliding movement, the spring 27 between the baffle block 26 and the regulating tube 10 is compressed. This increases the contact area between the air and the baffle block 26 after the air flows through the regulating tube 10, thereby creating a certain wind resistance and reducing the airflow rate. Conversely, the airflow rate increases.

For all the fixed connections mentioned above, welding is preferred.
