Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a water-based ink temperature control device for printing presses. Background Technology

[0002] With the development of modern industry, the printing industry occupies an important position in the production and manufacturing of various products. Whether it is paper publications such as books and magazines or product packaging, printing technology is indispensable. The quality and efficiency of printing directly affect the market competitiveness of products. In order to meet different printing needs, printing press technology is constantly being updated and improved.

[0003] The utility model patent application with publication number "CN206501566U" discloses a water-based ink temperature control device for a printing press, including an ink tank, a first semiconductor cooler, and a second semiconductor cooler. The ink tank has a cold air vent and a hot air vent at its bottom, and the first and second semiconductor coolers are installed inside the cold and hot air vents, respectively. A temperature sensor is located at the bottom of the ink tank. An ink pump is installed on the ink delivery pipe. A printing plate cylinder is located above the ink tank, and a doctor blade is installed on one side of the ink tank. The ink tank and the ink tank are connected by a return ink pipe, and a filter is installed at the connection between the ink tank and the return ink pipe. This water-based ink temperature control device for a printing press uses two sets of semiconductor coolers to cool and heat the water-based ink, controlling its temperature to remain between 15℃ and 28℃, a suitable temperature for printing. This achieves uniform temperature control of the water-based ink, accelerates the improvement of its stability, and maintains a relatively stable viscosity.

[0004] The water-based ink temperature control device for printing presses disclosed in the aforementioned document has the following defects: the plate roller cleaning mechanism of this technical solution is usually in constant contact with the plate roller. During the operation of the printing press, the plate roller rotates continuously, and this continuous contact will cause a large friction between the plate roller and the cleaning mechanism. The long-term friction will accelerate the wear of the plate roller, thereby shortening the service life of the plate roller. Frequent replacement of the plate roller not only increases production costs, but also affects the normal operation of the printing press and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a water-based ink temperature control device for a printing press. This device addresses the problem that the printing plate roller cleaning mechanism is constantly in contact with the printing plate roller. This continuous contact leads to significant friction between the printing plate roller and the cleaning mechanism, which accelerates wear and tear on the printing plate roller over time, thus shortening its service life. Frequent replacement of the printing plate roller not only increases production costs but also affects the normal operation of the printing press, ultimately reducing production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a water-based ink temperature control device for a printing press, comprising an ink tank, an ink reservoir, and a printing plate roller. The printing plate roller is positioned above the ink reservoir. A control panel is installed on one side of the ink tank. A temperature sensor is installed inside the ink tank. A cooler and a heater are installed inside the ink tank. An ink pump is provided on one side of the ink tank. The input end of the ink pump is connected to the inside of the ink tank. An input pipe is installed at the output end of the ink pump. Two sets of static mixers are installed on the outer surface of the input pipe. One end of the input pipe extends into the inside of the ink reservoir. A connecting pipe is installed on the lower surface of the ink reservoir and is connected to the ink tank. A cleaning mechanism is installed on one side of the ink reservoir.

[0008] The cleaning mechanism also includes a mounting frame, an electric push rod, guide slide rods, and a mounting housing. The mounting frame is mounted on the outer surface of the ink tank. An electric push rod is mounted on one side of the mounting frame. The output end of the electric push rod extends to the other side of the mounting frame. Two sets of guide slide rods are slidably connected inside the mounting frame. The output end of the electric push rod is mounted on the mounting housing. One side of the mounting housing is connected to one end of the two sets of guide slide rods.

[0009] Furthermore, the cleaning mechanism also includes springs, and several sets of springs are installed inside the mounting housing.

[0010] Furthermore, the cleaning mechanism also includes a movable plate, which is slidably connected inside the mounting housing, and the outer surface of the movable plate is connected to several sets of springs.

[0011] Furthermore, the cleaning mechanism also includes a scraper, which is installed on one side of the movable plate.

[0012] Furthermore, the scraper is disposed on one side of the printing plate roller.

[0013] Furthermore, a filter device is installed on the inner wall of one end of the connecting pipe.

[0014] This utility model has the following beneficial effects:

[0015] (1) When the printing plate roller needs to be cleaned, the electric push rod on one side of the mounting frame is activated. The output end of the electric push rod pushes the mounting shell to move. The mounting shell can move stably through the setting of the guide slide rod. When the mounting shell drives the scraper to contact the printing plate roller, it can effectively scrape off the ink residue and impurities on the surface of the printing plate roller. At the same time, it avoids the situation where the existing cleaning mechanism is constantly in contact with the printing plate roller, resulting in greater wear and easy damage.

[0016] (2) In this utility model, the movable plate slides inside the mounting shell. When the scraper abuts against the printing plate roller, the scraper squeezes the movable plate to slide inside and squeezes the spring at the same time. This allows the scraper to have a certain amount of room to move while abutting against and cleaning the printing plate roller, thus avoiding the scraper from damaging the printing plate roller.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-4 As shown, this utility model is a water-based ink temperature control device for a printing press, including an ink tank 1, an ink trough 2, and a printing plate roller 3. The printing plate roller 3 is located above the ink trough 2. A control panel 101 is installed on one side of the ink tank 1. A temperature sensor 102 is installed inside the ink tank 1. A cooler 103 and a heater 104 are installed inside the ink tank 1. An ink pump 4 is provided on one side of the ink tank 1. The input end of the ink pump 4 is connected to the inside of the ink tank 1. An input pipe 5 is installed at the output end of the ink pump 4. Two sets of static mixers 7 are installed on the outer surface of the input pipe 5. One end of the input pipe 5 extends into the inside of the ink trough 2. A connecting pipe 6 is installed on the lower surface of the ink trough 2 and is connected to the ink tank 1. A cleaning mechanism 8 is installed on one side of the ink trough 2.

[0027] The cleaning mechanism 8 also includes a mounting frame 801, an electric push rod 802, a guide slide rod 803, and a mounting shell 804. The mounting frame 801 is mounted on the outer surface of the ink tank 2. The electric push rod 802 is mounted on one side of the mounting frame 801. The output end of the electric push rod 802 extends to the other side of the mounting frame 801. Two sets of guide slide rods 803 are slidably connected inside the mounting frame 801. The output end of the electric push rod 802 is mounted on the mounting shell 804. One side of the mounting shell 804 is connected to one end of the two sets of guide slide rods 803.

[0028] The cleaning mechanism 8 also includes springs 805, and several sets of springs 805 are installed inside the mounting housing 804;

[0029] The cleaning mechanism 8 also includes a movable plate 806, which is slidably connected inside the mounting housing 804. The outer surface of the movable plate 806 is connected to several sets of springs 805.

[0030] The cleaning mechanism 8 also includes a scraper 807, which is installed on one side of the movable plate 806;

[0031] The scraper 807 is located on one side of the printing plate roller 3;

[0032] A filter device 9 is installed on the inner wall of one end of the connecting pipe 6.

[0033] In use, the temperature sensor 102 inside the ink tank 1 first monitors the temperature of the water-based ink in the ink tank 1 in real time. When the temperature sensor 102 detects that the ink temperature is too high, the control panel 101 receives the signal and starts the cooler 103 to cool down the ink. Conversely, when the ink temperature is detected to be too low, the heater 104 is started to heat up the ink, thereby controlling the ink temperature in the ink tank 1 within a suitable range. The ink pump 4 extracts the temperature-adjusted ink from the ink tank 1 and delivers it to the ink tank 2 through the input pipe 5. The two sets of static mixers 7 set on the input pipe 5 help to mix the ink evenly. The ink in the ink tank 2 flows back to the ink tank 1 through the connecting pipe 6 to form an ink circulation system, ensuring a continuous supply of ink and temperature stability. The filter device 9 installed on the inner wall of one end of the connecting pipe 6 filters the returned ink to remove any impurities that may be present, preventing impurities from affecting the ink quality and printing quality.

[0034] When it is necessary to clean the printing plate roller 3, the electric push rod 802 on one side of the mounting bracket 801 is activated. The output end of the electric push rod 802 pushes the mounting shell 804 to move. The mounting shell 804 can move stably through the setting of the guide slide rod 803. When the mounting shell 804 drives the scraper 807 to contact the printing plate roller 3, it can effectively scrape off the ink residue and impurities on the surface of the printing plate roller 3, avoiding the situation where the existing cleaning mechanism is constantly in contact with the printing plate roller 3, resulting in greater wear and easy damage.

[0035] The movable plate 806 slides inside the mounting housing 804. When the scraper 807 abuts against the printing plate roller 3, the scraper 807 squeezes the movable plate 806 to slide inside, while squeezing the spring 805. This allows the scraper 807 to have some room to move while abutting against and cleaning the printing plate roller 3, thus preventing the scraper 807 from damaging the printing plate roller 3.
