Description

Technical Field

[0001] This utility model belongs to the field of gravure printing ink evaporation reduction technology, specifically a gravure printing machine ink evaporation reduction structure. Background Technology

[0002] The solvents in ink have low boiling points and easily transform from liquid to gas at room temperature. As the temperature rises, the kinetic energy of the solvent molecules in the ink increases. If this energy exceeds the intermolecular attraction, the solvent will escape from the liquid surface and accumulate, resulting in a reduction in ink volume.

[0003] Chinese Patent CN211054683U discloses an ink tank device for a gravure printing machine that can reduce the evaporation of ink solvents. The device includes a printing plate roller, an ink tank body connected to the lower side of the printing plate roller, the ink tank body being filled with ink, an ink delivery roller being rolled and connected to the upper part of the ink relative to the lower end of the printing plate roller, a rear baffle fixedly connected to one end of the ink tank body, a front baffle connected to the other end of the ink tank body, and a fixing frame connected to both sides of the front baffle body, with an anti-evaporation baffle slidably connected inside the fixing frame.

[0004] However, during the implementation of the relevant technology, it was found that the above-mentioned gravure printing machine ink tank device for reducing ink solvent evaporation only adds a cover plate to block the ink solvent, but cannot collect the evaporating ink, and the evaporating harmful gases will spread into the workshop, seriously affecting the health of machine operators. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a structure for reducing ink evaporation in a gravure printing machine. It includes a storage box added to the ink tank for cooling the ink and collecting evaporating ink. When the ink is heated to a high temperature and is not in operation, the hot ink is discharged into the storage box. A cooling plate in the storage box cools the hot ink solvent. A cover plate works in conjunction with the outer shell to liquefy the evaporating ink and collect it back into the ink tank. Activated carbon filters the harmful gases generated by ink evaporation, minimizing the leakage of harmful gases and reducing ink evaporation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gravure printing press structure that reduces ink evaporation, including...

[0007] An ink tank has an outer shell fixedly connected to a collection tank with its opening facing upwards. Side plates are fixedly connected to the ends of the outer shell. A waste drain hole is penetrating the bottom of the ink tank.

[0008] The ink tank is equipped with a support rod, and the cover plate is fixedly equipped with a support ring. The support ring has an opening, and the cover plate is rotatably snapped onto the support rod through the opening of the support ring. The ink tank is equipped with a storage box, and the storage box is equipped with a collection groove. The surface of the storage box is equipped with a through hole connecting to the collection groove. The collection groove is equipped with a cooling plate, and activated carbon is fixedly connected to the surface of the cover plate.

[0009] The cover plate is fixedly connected to handles on its surface, and a through groove is provided between the two sets of handles. An observation panel is provided in the through groove of the cover plate.

[0010] Preferably, the surface of the side plate is provided with a support assembly, the support assembly including an extension rod, the extension rod being fixedly disposed on the inner wall of the side plate, the front end of the extension rod being rotatably connected to a retaining pin, the side of the retaining pin being fixedly connected to a fixing seat, the inside of the fixing seat being rotatably connected to a sliding rod, and the outside of the sliding rod being sleeved with a spring.

[0011] Preferably, a base extends through the outer side of the slide rod, the spring abuts against the top of the base, the other end of the base is fixedly mounted on the surface of the side plate, and one side of the cover plate abuts against the surface of the abutment pin.

[0012] Preferably, the slide bar has several sets of circular slots on its surface, and a locking pin is provided in the circular slot of the slide bar, the locking pin abutting against the surface of the base.

[0013] Preferably, the support components are provided in two sets, and are symmetrically arranged on the inner walls of the two sets of side plates.

[0014] Preferably, the cooling is performed using a passive cooling method, and a micro power pump is installed inside. The internal structure is inclined, and the position of the left through hole is higher than that of the right through hole. The micro power pump transmits heat from the high-temperature area to the low-temperature area.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention adds a storage box to the ink cartridge. When the ink temperature is high, the hotter ink is exchanged with the cooler ink in the storage box, and the hotter ink flows into the storage box. A cooling plate cools down the relatively hot ink. The inner wall of the cover plate is made of a material with poor thermal conductivity to reduce heat transfer and prevent the cover plate from heating up along with the ink temperature. When the ink heats up and volatilizes, the gaseous ink solvent comes into contact with the surface of the cover plate. Since the cover plate is a poor conductor of heat and its temperature is lower than that of the ink itself, the gaseous ink solvent will liquefy when it encounters the cooler cover plate. The liquefied ink solvent flows into the ink tank, thus reducing ink evaporation.

[0017] A cover plate is added to the surface of the ink tank to prevent solvent from splashing during operation. When the ink is used inside the printing press, the cover plate blocks the volatile solvent. Activated carbon is added to the inner wall of the cover plate to adsorb the solvent and harmful gases released during operation, preventing them from escaping. When changing to different sizes of printing rollers, the cover plate needs to be moved closer to the surface of the printing roller to improve the anti-evaporation effect. This can be achieved by adjusting the angle of the locking pin. The locking pin is pressed down to overcome the spring force, and the locking pin is adjusted to a higher circular groove to lock the locking pin. This lowers the height of the locking pin, allowing the cover plate to be closer to the printing roller. Attached Figure Description

[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 a structure for reducing ink evaporation in a gravure printing machine, including an ink tank 1, an outer shell 2 fixedly connected to the upward-opening collection tank of the ink tank 1, side plates 3 fixedly connected to the surface end of the outer shell 2, and a waste discharge hole penetrating the bottom end of the ink tank 1.

[0026] The ink tank 1 is provided with a support rod 5, and a support ring 42 is fixedly provided on the cover plate 4. One end of the support ring 42 is provided with an opening. The cover plate 4 is rotatably locked onto the support rod 5 through the opening of the support ring 42. A storage box 7 is fixedly connected to the surface of the ink tank 1. A collection groove is provided in the inner cavity of the storage box 7. A through hole 71 is provided on the surface of the storage box 7. A cooling plate 72 is provided in the collection groove. Two sets of activated carbon 8 are fixedly connected to the surface of the cover plate 4.

[0027] Handles 41 are fixedly connected to the surface of the cover plate 4, and a through groove is provided between the two sets of handles 41. An observation panel 43 is provided inside the through groove of the cover plate 4.

[0028] Example 1: During the printing process, the ink temperature rises due to the influence of the printing roller. When the temperature sensor in the ink tank 1 detects that the ink temperature is high, it activates the micro power pump in the ink tank 1 to make the ink flow and reduce the temperature of the cooling plate 72. There are many ways to reduce the temperature of the cooling plate 72, such as passing cooling water through it or connecting a semiconductor cooling chip. The ink flows from a through hole 71 on the surface of the storage box 7 to the cooling plate 72. Since the inside of the storage box 7 is not flat, the ink comes into contact with the cooling plate 72 at a lower position and cools down. The micro power pump inside the storage box 7 pushes the ink to flow. After cooling, the ink is discharged from another set of through holes 71 and returns to the storage box 7.

[0029] Specifically, a support assembly 6 is provided on the surface of the side plate 3. The support assembly 6 includes an extension rod 66, which is fixedly installed on the inner wall of the side plate 3. A clamping pin 62 is rotatably connected to the front end of the extension rod 66. A fixing seat 63 is fixedly connected to the side of the clamping pin 62. A sliding rod 64 is rotatably connected inside the fixing seat 63. A spring 65 is sleeved on the outer side of the sliding rod 64. A base 61 passes through the outer side of the sliding rod 64. The spring 65 abuts against the top of the base 61. The other end of the base 61 is fixedly installed on the surface of the side plate 3. One side of the cover plate 4 abuts against the surface of the clamping pin 62.

[0030] When replacing the smaller printing roller, the cover plate 4 needs to be moved towards the inner wall of the outer shell 2. At this time, the cover plate 4 is pressed closer to the surface of the printing roller. The cover plate 4 presses against the clamping pin 62. The fixing seat 63 on the surface of the clamping pin 62 overcomes the resistance of the spring 65 and slides into the interior of the base 61. The locking pin 67 is inserted into the round hole groove protruding from the position of the slide rod 64 from the base 61 to lock the position of the clamping pin 62 and stop pressing the cover plate 4. Since the locking pin 67 is pressed against the base 61, the spring 65 cannot recover its deformation. The clamping pin 62 is in the adjusted position, and the cover plate 4 can be closer to the printing roller, which can better prevent ink splashing and reduce the amount of ink in the ink tank 1.

[0031] Example 2: When the printing press is used for a long time, harmful gases will escape from the inside of the ink tank 1 to the outside space. The high-temperature gas solvent comes into contact with the surface of the cover plate 4. When the high-temperature gas encounters the cover plate 4 with a lower surface temperature, it will liquefy (since the cover plate 4 does not contact the printing roller, its temperature will be lower than the temperature of the ink). The liquefied ink solvent flows from the inner wall of the cover plate 4 to the collection tank of the ink tank 1.

[0032] It is worth noting that there are two sets of support components 6, which are symmetrically arranged on the inner walls of the two sets of side plates 3.

[0033] It is worth noting that the cooling plate 72 adopts a passive cooling method. The storage box 7 is equipped with a micro power pump. The storage box 7 has an inclined structure, and the position of the left through hole 71 is higher than that of the right through hole 71. The micro power pump transmits from the high temperature area to the low temperature area, so that the ink with a higher temperature is transported from above the storage slot in the storage box 7 into the storage slot.
