Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a heating device for printing ink. Background Technology

[0002] Printing ink is an essential material used in printing. It transfers patterns and text onto a substrate through printing or inkjet printing. Printing ink consists of main and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid. Because printing ink exhibits good fluidity at high temperatures, it is typically heat-treated before entering the printing press.

[0003] Because the ink is quite viscous, it tends to accumulate on the inner wall of the barrel after heat treatment. In the existing technology, it is usually cleaned manually. Since the barrel is deep, this increases the workload of the operators and affects the heating efficiency.

[0004] Therefore, it is necessary to propose a heating device for printing ink to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for printing inks to solve the problem that in the prior art, manual cleaning is usually required, which increases the workload of operators and affects heating efficiency due to the depth of the container.

Detailed Implementation

[0023] This utility model provides, for example Figures 1-3 The heating device for printing ink shown includes a heating cylinder 1 with a thick side wall. A heating ring cavity 2 is formed inside the side wall of the heating cylinder 1. A coil 3 is fixedly installed inside the heating ring cavity 2. An inlet pipe 4 and an outlet pipe 5 are fixedly connected to the outer wall of the heating cylinder 1. The inlet pipe 4 and the outlet pipe 5 are respectively connected to the two ends of the coil 3.

[0024] The inlet pipe 4 is connected to the factory's hot water supply pipeline, and the outlet pipe 5 is connected to the factory's suction pipeline. Hot water is supplied from the inlet pipe 4 to the inside of the coil 3. The hot water flows inside the coil 3 and is discharged from the outlet pipe 5, thereby heating the ink inside the heating cylinder 1. In addition, a hot water circulation device, including a pump body and heating elements (electric heating wire), can be installed between the inlet pipe 4 and the outlet pipe 5 to realize the recycling of hot water. This can be adjusted according to the specific usage.

[0025] Furthermore, the temperature of the hot water is suitable and will not affect the quality of the ink.

[0026] To improve the heating effect, a sliding plate 6 is slidably arranged inside the heating cylinder 1, a rotating shaft 7 is rotatably arranged on the sliding plate 6, and a stirring blade 8 is fixedly connected to the rotating shaft 7. Multiple stirring blades 8 are arranged. A motor 9 is fixedly connected to the bottom of the sliding plate 6, and the rotating shaft 7 is fixedly connected to the drive shaft of the motor 9.

[0027] A rubber pad or similar material can be placed between the sliding plate 6 and the inner wall of the heating cylinder 1 to reduce wear.

[0028] The bottom of the slide plate 6 may be equipped with a power supply device to power the motor 9, which may include a battery or similar structure.

[0029] The motor 9 drives the stirring blade 8 to rotate via the rotating shaft 7, which agitates the ink and improves the heating effect.

[0030] After heating is complete, when the control slide 6 slides upward inside the heating cylinder 1, the slide 6 will push and scrape the ink on the inner wall of the heating cylinder 1 upward, so that the ink is in the upper half of the heating cylinder 1, which is convenient for material discharge. At the same time, it will complete the scraping and cleaning of the inner wall of the heating cylinder 1. When the slide 6 slides to the top opening position of the heating cylinder 1, the operator only needs to clean the upper surface of the slide 6. At this time, the slide 6 is located at the top opening position of the heating cylinder 1, which is convenient for operation.

[0031] During heating and stirring, the sliding plate 6 can also be controlled to slide up and down inside the heating cylinder 1 to assist in mixing.

[0032] This invention improves the heating effect by setting up structures such as the sliding plate 6 to agitate the ink, and facilitates the scraping and cleaning of the inner wall of the heating cylinder 1. It can also assist in stirring and improve the efficiency of the heating device for printing ink.

[0033] A bottom cylinder 11 is fixedly connected to the bottom of the heating cylinder 1. An electric push rod 12 is fixedly installed inside the bottom cylinder 11. A through hole 13 is opened at the top of the bottom cylinder 11, and the through hole 13 penetrates the bottom end of the heating cylinder 1. The telescopic end of the electric push rod 12 passes through the through hole 13, and the sliding plate 6 is fixedly connected to the telescopic end of the electric push rod 12. When the telescopic end of the electric push rod 12 is extended, it will drive the sliding plate 6 to slide upward inside the heating cylinder 1; when the telescopic end of the electric push rod 12 is extended, it will drive the sliding plate 6 to slide downward inside the heating cylinder 1.

[0034] A vent 10 is provided at the bottom of the side wall of the heating cylinder 1, and the vent 10 is connected to the position of the heating cylinder 1 below the sliding plate 6. When the sliding plate 6 slides upward inside the heating cylinder 1, external gas enters the position of the heating cylinder 1 below the sliding plate 6 through the vent 10; when the sliding plate 6 slides downward inside the heating cylinder 1, the gas in the position of the heating cylinder 1 below the sliding plate 6 is discharged through the vent 10, without affecting the up and down movement of the sliding plate 6, and a sponge filter plate or the like can be installed at the vent 10 to prevent impurities from entering.

[0035] The top of the heating cylinder 1 is fitted with a cover plate 18. Before heating and stirring, the cover plate 18 is removed and the material is fed from the top of the heating cylinder 1. During heating and stirring, the cover plate 18 closes the top of the heating cylinder 1. When discharging or cleaning, the cover plate 18 is removed and the material is sucked out.

[0036] Considering that the ink will produce some volatile organic gases during the heating process, if these gases are directly released into the air, they will have a certain impact on the health of the operators. To treat these gases, an exhaust pipe 14 is fixedly connected to the cover plate 18. The exhaust pipe 14 is connected to the factory's centralized air treatment pipeline and is connected to the interior of the heating cylinder 1. A first one-way valve 15 is installed on the exhaust pipe 14, allowing the volatile gases to be discharged outwards without reverse flow. An inlet pipe 16 is fixedly connected to the cover plate 18 and is connected to the factory's purified gas delivery pipeline. The inlet pipe 16 is connected to the interior of the heating cylinder 1 and is installed on the inlet pipe 16. A second one-way valve 17 is installed on the inlet pipe 16, allowing the purified gas to enter the interior of the heating cylinder 1 without reverse flow. Furthermore, the purified gas has a certain temperature and will not affect the heating of the ink.

[0037] When volatile gases are discharged, the sliding plate 6 can be controlled to slide upward inside the heating cylinder 1 to push out the volatile gases and accelerate the discharge speed of the volatile gases. When the sliding plate 6 moves downward to reset, the purified gas enters the heating cylinder 1 without affecting the movement of the sliding plate 6.
