Description

Technical Field

[0001] The utility model relates to the technical field of ink production, in particular to an ink cooling and stirring device. Background Art

[0002] Ink is an important material used in printing. It is a viscous body formed by fully mixing resin, pigment, filler and other auxiliary ingredients. An ink cooling device is required during the cooling process of the ink.

[0003] In the prior art, the main reason for cooling the ink during its production process is to control the temperature of the ink, thereby ensuring the stability of its quality and performance.

[0004] In the production process of ink, temperature is a very important factor. Too high temperature may cause chemical reactions in certain components of the ink, changing its original properties, such as viscosity, color, etc.

[0005] This may affect the printing effect of the ink or even cause problems during the use of the ink.

[0006] In the process of stirring and cooling the ink, the existing ink cooling and stirring device usually adopts natural wind cooling or the flow of refrigerant on the top of the ink to absorb heat and cool down the ink. However, this method is prone to the problem of heat difference between the upper and lower layers of the ink, resulting in the ink on the bottom side of the stirring barrel cannot be cooled in time, which is prone to the problem of ink stratification and discoloration. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an ink cooling and stirring device so as to solve the technical problems mentioned in the above background technology.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] An ink cooling and stirring device comprises a processing cylinder, a fixed cylinder is arranged inside the processing cylinder, four extension tubes are arranged on the outer peripheral side of the fixed cylinder near the top surface, and a connecting tube passing through the processing cylinder is arranged at the bottom end of the fixed cylinder, a water circulation mechanism is arranged at the bottom end of the processing cylinder, and a spiral disk is arranged inside the fixed cylinder.

[0010] Furthermore, a cavity is provided inside the wall of the fixed tube, and the extension tube and the connecting tube are both connected to the cavity.

[0011] Furthermore, the water circulation mechanism includes a fixed water tank, which is fixedly connected to the bottom end of the treatment cylinder, and a water pipe connected to the extension pipe is arranged on the outer peripheral side of the fixed water tank, and a driving water pump is arranged inside the fixed water tank, and the driving water pump is connected to the connecting pipe.

[0012] Furthermore, one end of the extension tube away from the fixed tube passes through the processing tube, and the outer surface of the extension tube extending out of the processing tube and the outer surface of the water guide tube are both provided with cooling fins.

[0013] Furthermore, the shaft of the spiral disk passes through the bottom end of the fixed cylinder and is interconnected with the driving shaft of the driving water pump.

[0014] Furthermore, the inner bottom end of the processing cylinder is arc-shaped, and the arc surface extends to the bottom end of the fixing cylinder.

[0015] In summary, the present invention includes at least one of the following beneficial technical effects:

[0016] 1. The ink cooling and stirring device pours the ink to be cooled into the inside of the treatment cylinder, and through the setting of the spiral disk, the ink is transported upward from the inside of the fixed cylinder, so that the ink is not discharged through the fixed cylinder, and then flows out from the outer surface of the fixed cylinder. Cooling water is introduced into the inside of the cylinder wall of the fixed cylinder through the water circulation mechanism, and then in the process of the ink flowing on the surface of the fixed cylinder, the heat inside the ink is conducted to the inside of the cooling water through the fixed cylinder, so as to achieve the purpose of cooling the ink, and because the ink at the bottom can flow to the upper end during the upward transmission process, the ink is continuously stirred, and the uneven cooling of the ink is avoided;

[0017] 2. This ink cooling and stirring device drives a water pump to pump cooling water into the interior of a fixed cylinder through a connecting pipe, and then discharges the cooling water through an extension pipe on the top of the fixed cylinder, and then flows back through the water guide pipe to the interior of a fixed water tank, thereby achieving the purpose of recycling the cooling water. When the cooling water flows through the water guide pipe, the heat absorbed by the cooling water is discharged to the outside of the air through the setting of cooling fins. Since four extension pipes are provided, the cooling water passing through the cavity will be divided into four parts, which will be discharged through extension pipes at different positions respectively, thereby achieving the purpose of improving the heat dissipation efficiency of the cooling water.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 3 The utility model discloses an ink cooling and stirring device, including a processing cylinder 1, a fixed cylinder 2 is arranged inside the processing cylinder 1, four extension tubes 3 are arranged on the outer peripheral side of the fixed cylinder 2 near the top surface, and a connecting tube 4 penetrating the processing cylinder 1 is arranged at the bottom end of the fixed cylinder 2, a water circulation mechanism 5 is arranged at the bottom end of the processing cylinder 1, and a spiral disk 6 is arranged inside the fixed cylinder 2.

[0026] In this embodiment, when the device is in use, the ink that needs to be cooled is poured into the interior of the processing cylinder 1. The spiral disk 6 is used to transport the ink upward from the interior of the fixed cylinder 2, so that the ink is discharged through the fixed cylinder 2 and flows out from the outer surface of the fixed cylinder 2 by gravity. At the same time, cooling water is introduced into the interior of the cylinder wall of the fixed cylinder 2 through the water circulation mechanism 5. Then, in the process of the ink flowing on the surface of the fixed cylinder 2, the heat inside the ink is conducted to the interior of the cooling water through the fixed cylinder 2, thereby achieving the purpose of cooling the ink.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a cavity 7 is provided inside the wall of the fixed tube 2 , and the extension tube 3 and the connecting tube 4 are both connected to the cavity 7 .

[0028] In this embodiment, cooling water is introduced into the interior of the cavity 7 through the water circulation mechanism 5, and is discharged through the extension tube 3, and the cooling water enters the interior of the water circulation mechanism 5 again, thereby achieving the purpose of recycling the cooling water, and the connecting tube 4 lifts up the fixed tube 2 so that there is a gap between the bottom end of the fixed tube 2 and the inner bottom surface of the processing tube 1.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the water circulation mechanism 5 includes a fixed water tank 51, which is fixedly connected to the bottom end of the treatment tube 1. A water pipe 52 connected to the extension pipe 3 is arranged on the outer peripheral side of the fixed water tank 51. A driving water pump 53 is arranged inside the fixed water tank 51, and the driving water pump 53 is connected to the connecting pipe 4.

[0030] In this embodiment, a fixed water tank 51 is provided for storing cooling water, and a water pipe 52 is provided to connect the side surface of the fixed water tank 51 with the extension pipe 3. When in use, the cooling water is pumped into the interior of the fixed cylinder 2 through the connecting pipe 4 by driving the water pump 53, and then discharged through the extension pipe 3 at the top of the fixed cylinder 2, and then refluxed through the water pipe 52 to the interior of the fixed water tank 51, thereby achieving the purpose of circulating the cooling water.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, one end of the extension tube 3 away from the fixed tube 2 passes through the treatment tube 1 , and the outer surface of the extension tube 3 extending out of the treatment tube 1 and the outer surface of the water guide tube 52 are both provided with cooling fins 54 .

[0032] In the present embodiment, when the cooling water flows through the cavity 7 in the fixed cylinder 2 to the extension tube 3, and in the process of flowing to the inside of the fixed water tank 51 through the water pipe 52 under the action of gravity, the heat absorbed by the cooling water is discharged to the outside of the air through the setting of the cooling fins 54. Since there are four extension tubes 3, the cooling water passing through the cavity 7 will be divided into four parts and discharged through the extension tubes 3 at different positions respectively, thereby achieving the purpose of improving the heat dissipation efficiency of the cooling water.

[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the shaft of the spiral disk 6 passes through the bottom end of the fixed cylinder 2 and is connected to the driving shaft of the driving water pump 53.

[0034] In this embodiment, by setting the spiral disk 6 that is interconnected by the shaft and the driving water pump 53, when the water pump pumps cooling water into the interior of the cavity 7, the ink is passed into the interior of the fixed cylinder 2, so that the ink and the cooling water move upward synchronously, thereby achieving the purpose of improving the efficiency of heat transfer.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the inner bottom end of the processing cylinder 1 is arc-shaped, and the arc surface extends to the bottom end of the fixed cylinder 2.

[0036] In this embodiment, by configuring the processing cylinder 1 with an arc-shaped inner bottom surface, after the ink enters the processing cylinder 1, it can automatically flow to the bottom side of the fixed cylinder 2, thereby achieving the effect of facilitating the spiral disk 6 to lift the ink upward.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
