Description

Technical Field

[0001] This utility model relates to a cooling device for ink production, belonging to the field of ink production technology. Background Technology

[0002] During the use of a printing press, especially during continuous use, the ink temperature rises due to prolonged circulation, which can easily reduce the ink viscosity and increase its fluidity. This can lead to printing defects such as missing dots and broken strokes when printing lines and text on uneven paper, thus affecting the quality of the printed product. Therefore, printing presses are usually equipped with ink cooling devices to reduce the ink temperature.

[0003] Existing ink cooling devices generally include a water-cooled box and an ink tank. The water-cooled box is usually equipped with a delivery pipe for conveying ink, which is also connected to the ink tank. By immersing the delivery pipe in the water-cooled box, heat exchange occurs between the cooling water and the ink in the delivery pipe to cool the ink.

[0004] However, due to the poor fluidity of the liquid in the water-cooled box, the temperature of the coolant around the delivery pipe is easily higher than that of the coolant in other parts of the water-cooled box. This uneven heat exchange of the coolant reduces the heat exchange efficiency between the liquid in the water-cooled box and the ink in the delivery pipe, which in turn reduces the cooling efficiency of the ink. Utility Model Content

[0015] Figure 2 yes Figure 1 A structural sectional view. Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] like Figure 1-2As shown, a cooling device for ink production includes a housing 1. The housing 1 contains a cooling chamber 2 and a liquid storage chamber 3 adjacent to the cooling chamber 2. The cooling chamber is filled with a large amount of coolant (such as cold water), but not completely filled, and the delivery pipe is completely submerged. The liquid storage chamber stores the heated ink. The cooling chamber 2 contains an S-shaped delivery pipe 21. One end of the delivery pipe 21 passes through the side wall of the cooling chamber 2 and connects to external ink-using equipment. The other end of the delivery pipe 21 passes through the cooling chamber 2 and connects to the liquid storage chamber 3. The ink flows through the cooling chamber via the delivery pipe in the liquid storage chamber and then outwards to the ink-using equipment, thus achieving ink cooling and recycling. The delivery pipe 21 is longitudinally arranged, with an S-shaped bend, and is made of copper for better cooling. Multiple longitudinally arranged rotating shafts 22 are located on the side of the delivery pipe 21. The top of each rotating shaft 22 is connected to the top wall of the cooling chamber 2, and the bottom of each rotating shaft 22 has multiple... A horizontally rotatable fan blade 23 is provided. The bottom of the cooling chamber 2 is provided with a liquid delivery pipe 24 for transferring the coolant at the bottom of the cooling chamber 2 to the top of the cooling chamber 2 and discharging it into the cooling chamber 2. The upper end of the rotating shaft is fixed to the top of the cooling chamber, while the lower end of the rotating shaft is provided with a horizontally rotatable fan blade. The fan blade is located in the middle of the cooling chamber. The coolant at the bottom of the cooling chamber is controlled to flow towards the top of the cooling chamber and discharge into the cooling chamber through the liquid delivery pipe, realizing the circulation of the coolant. This can avoid the heat-affected area of ​​the coolant being too concentrated, which would lead to uneven heat exchange of the coolant. This allows the heat energy of the coolant heat exchange to be more evenly distributed throughout the entire area of ​​the coolant. At the same time, when the coolant in the cooling chamber is transported and flows, the fan blade will be driven by the flowing coolant to rotate, which will agitate the coolant on the surrounding side, increase the heat dispersion effect of the coolant, enhance the heat exchange uniformity of the coolant, effectively improve the heat exchange efficiency of the coolant, and improve the cooling efficiency of the ink.

[0018] like Figure 1-2 As shown, the liquid delivery pipeline 24 includes a first pipeline 241 located at the bottom of the cooling chamber 2 and a second pipeline 242 located at the top of the cooling chamber 2. The inlet of the first pipeline 241 is connected to a first pump body 243 located at the bottom of the inner wall of the cooling chamber 2. The first pump body is a liquid pump. After the first pump body is started, it pumps the coolant at the bottom of the cooling chamber. The coolant is pumped into the first pipeline by the first pump body. The first pipeline delivers the coolant to the second pipeline and discharges it from the top of the cooling chamber to recombine with the coolant, realizing the circulation and flow of the coolant. This makes the coolant heat more evenly and improves the heat exchange efficiency. The outlet of the second pipeline 242 is located at the top of the inner wall of the cooling chamber 2. The bottom of the liquid storage chamber 3 is provided with a second pump body 36 connected to one end of a delivery pipe 21. The second pump body is an oil pump. The second pump body pumps the ink at the bottom of the liquid storage chamber, causing the ink to flow in the delivery pipe and through the coolant. Finally, the cooled ink is delivered to the external equipment through the delivery pipe, realizing the circulation, cooling and delivery of the ink.

[0019] like Figure 1-2As shown, the liquid storage chamber 3 has an inlet pipe 31 in the middle for conveying heated ink. One end of the inlet pipe 31, located inside the liquid storage chamber 3, is bent upwards to form a curved section 311. The outlet of the curved section 311 extends outwards in a funnel shape. The inlet pipe conveys the externally heated ink into the liquid storage chamber. The ink flows along the inlet pipe to the curved section and surges upwards, causing the ink to scatter and fall downwards in an open manner, thereby increasing the heat dissipation efficiency of the ink without affecting the delivery of the ink. The funnel-shaped outlet of the curved section reduces the pressure on the ink when it surges out, reduces the height of the ink surge, reduces contamination of the components above the inlet pipe, and enhances the heat dissipation effect. The top of the liquid storage chamber 3 has multiple fans 32 that blow air towards the curved section 311 of the inlet pipe 31. The top of the housing 1 has a control module 11 for controlling the start, stop, and speed of the fans 32. The control module is existing technology and can control the start, stop, and speed of the fans, so that when the fans blow air downwards towards the surging ink, the speed can be adjusted according to the heat dissipation. The fan speed can be adjusted according to the effect and needs, and the start and stop of the fan can be controlled for greater convenience. A baffle 33 is provided between the fan 32 and the curved section 311. The baffle 33 has multiple holes 331. The baffle can increase the obstruction of the flowing ink, prevent ink from splashing and contaminating the fan, and affect the fan's blowing effect. At the same time, it can ensure that the air force can pass through the holes to cool the flowing ink. The top of the liquid storage chamber 3 is provided with a ventilated net 34 that communicates with the outside. The ventilated net is set to promote gas flow and prevent excessive pressure in the liquid storage chamber. At the same time, the hot air in the liquid storage chamber can float up and be discharged through the ventilated net, preventing the accumulation of hot air in the liquid storage chamber and improving the heat dissipation effect. On the inner wall of the liquid storage chamber 3, corresponding to the lower part of the liquid inlet pipe 31, there are multiple staggered and equally spaced guide plates 35. Each guide plate 35 is inclined downward. The guide plates can increase the fluidity of the ink, prolong the ink cooling time, and improve the cooling effect of the ink. This allows the ink to be cooled faster as it flows through the cooling chamber, enhancing the cooling effect of the ink.

[0020] like Figure 1-2 As shown, the first pipe 241 extends to the outside of the housing 1 and connects to one end of the third pipe 244. The other end of the third pipe 244 extends to the space between the partition 33 and the fan 32 in the liquid storage chamber 3. The third pipe 244 is arranged in an S-shape between the partition 33 and the fan 32. The third pipe 244 extends to the outside of the liquid storage chamber 3 and connects to the second pipe 242. After the coolant enters the first pipe, the S-section of the S-shape structure flowing from the first pipe to the third pipe is located below the fan. When the coolant flows through, it can achieve a cooling effect through the fan, which improves the cooling speed of the coolant. The cooled coolant returns to the cooling chamber through the second pipe, which further improves the cooling speed of the coolant. This allows the coolant to cool quickly in the circulation flow, improving the cooling effect of the coolant. At the same time, it does not affect the fan's cooling of the ink in the storage chamber, resulting in higher utilization and saving cooling costs.

[0021] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
