Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a rapid ink supply device for a printing press. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms such as plate mounting, inking, printing, and paper feeding (including folding). Its principle is to first make a printing plate of the text or image to be printed, mount it on the printing press, and then apply ink to the areas of the printing plate with text and images by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles or metal plates). The printing press inking system is the core component of printing equipment, and its performance directly affects printing quality and efficiency.

[0003] Currently, high-speed printing presses have increasingly higher requirements for the response speed and stability of the ink supply system. During high-speed printing, ink is consumed quickly, which can easily lead to insufficient or uneven ink supply. In such cases, it is necessary to stop the machine to replace the ink. The replacement process requires stopping the equipment and then turning on the ink supply equipment to add ink, which is a cumbersome process and affects the printing efficiency of the equipment.

[0004] Therefore, it is necessary to invent a rapid ink supply device for printing presses to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fast ink supply device for printing presses, so as to solve the problem that the ink filling process is cumbersome and affects the printing efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid ink supply device for a printing press, comprising a mounting plate, an ink supply pump mounted on the lower side of the mounting plate, and two sets of ink supply components arranged between the mounting plate and the ink supply pump. Each ink supply component includes a hopper, a solenoid valve, a connecting pipe, a liquid level sensor, a transfer cylinder, an ink inlet pipe, an exhaust pipe, an ink outlet pipe, an ink storage bottle, and a connector. The transfer cylinder is installed between the mounting plate and the ink supply pump.

[0007] By adopting the above technical solution, the ink inside the ink reservoir is injected into the hopper, and then injected into the transfer cylinder through the hopper. At this time, the ink supply pump draws the ink from the transfer cylinder to supply ink to the printer.

[0008] Optionally, the ink discharge pipe is fixedly connected to the lower end of the transfer cylinder, the end of the ink discharge pipe away from the transfer cylinder is fixedly connected to the ink inlet end of the ink supply pump, and the ink outlet end of the ink supply pump is fixedly connected to the ink supply pipe.

[0009] By adopting the above technical solution, the ink supply pump draws ink from inside the transfer cylinder through the ink discharge pipe.

[0010] Optionally, two sets of feeding hoppers are fixedly connected to the lower surface of the mounting plate. Solenoid valves are fixedly installed at the lower ends of the feeding hoppers. Ink inlet pipes are fixedly connected to the lower ends of the two sets of solenoid valves. The lower ends of the two sets of ink inlet pipes are fixedly connected to the left and right sides of the central rotating cylinder, respectively.

[0011] By adopting the above technical solution, the solenoid valve is used to control the discharge port at the lower end of the hopper, and the ink inside the hopper is injected into the interior of the transfer cylinder through the ink inlet pipe.

[0012] Optionally, the upper end of the transfer cylinder is fixedly connected to two sets of exhaust pipes, and the upper end of the exhaust pipes is fixedly connected to the mounting plate.

[0013] By adopting the above technical solution, the exhaust pipe keeps the interior of the transfer cylinder at normal pressure, ensuring the speed of ink discharge.

[0014] Optionally, a connecting pipe is fixedly connected to the upper surface of the mounting plate at the position above the two sets of hoppers, and a liquid level sensor is fixedly connected to the upper surface of the mounting plate at the position on the side of the two sets of connecting pipes.

[0015] By adopting the above technical solution, the liquid level sensor is used to observe the liquid level inside the hopper. When there is a lack of ink inside the hopper, the lower solenoid valve is automatically closed and the other solenoid valve is opened.

[0016] Optionally, a support frame is fixedly connected to the inner wall of the connecting pipe, and an ink guide cone is fixedly connected to the center of the support frame. Multiple sets of ink guide grooves are opened on the side of the ink guide cone.

[0017] By adopting the above technical solution, the ink guide cone is inserted into the inside of the ink reservoir to guide the ink inside.

[0018] Optionally, a connector is fixedly connected to the lower end of the ink reservoir, the connector is threadedly connected to a connecting pipe, and a sealing paper is bonded to the lower end of the connecting pipe.

[0019] By adopting the above technical solution, the connector is threaded to the connecting pipe. At this time, the ink guide cone will penetrate the sealing paper and insert into the inside of the ink storage bottle. The ink inside the ink storage bottle will then enter the hopper through the ink guide groove.

[0020] Optionally, an electric motor is fixedly installed on the upper surface of the transfer cylinder, and a connecting rod is fixedly connected to the output end of the electric motor. Both ends of the connecting rod are fixedly connected to stirring rods.

[0021] By adopting the above technical solution, the electric motor is used to drive the connecting rod to rotate, and the connecting rod drives the stirring rod to rotate, thereby stirring the ink inside the transfer cylinder and preventing ink sedimentation that could cause blockage of the ink discharge pipe.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model utilizes two sets of ink storage bottles, a feeding hopper, a solenoid valve, a liquid level sensor, and a transfer cylinder. During use, one set of solenoid valves opens, allowing ink from the corresponding ink storage bottle to flow into the transfer cylinder through the feeding hopper. Once the ink in the feeding hopper is drained, the lower solenoid valve closes, while the other solenoid valve opens, allowing the other ink storage bottle and feeding hopper to supply ink. At this time, the depleted ink storage bottle can be replaced, ensuring normal ink supply during replacement. This enables continuous printing, avoids printing interruptions, and improves print quality and efficiency.

[0024] 2. In the process of ink supply, the electric motor drives the connecting rod to rotate, which in turn drives the stirring rod to rotate, thus stirring the ink inside the transfer cylinder. This prevents ink from settling and causing blockage of the ink discharge pipe, thereby further improving print quality and printing efficiency. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1 to 6 The printing press rapid ink supply device shown includes a mounting plate 1, an ink supply pump 3 mounted on the lower side of the mounting plate 1, and two sets of ink supply components arranged between the mounting plate 1 and the ink supply pump 3. The ink supply components include a hopper 11, a solenoid valve 12, a connecting pipe 13, a liquid level sensor 17, a transfer cylinder 2, an ink inlet pipe 21, an exhaust pipe 22, an ink outlet pipe 23, an ink storage bottle 4, and a connector 41. The transfer cylinder 2 is installed between the mounting plate 1 and the ink supply pump 3. An electric motor 24 is fixedly mounted on the upper surface of the transfer cylinder 2. A connecting rod 25 is fixedly connected to the output end of the electric motor 24. A stirring rod 26 is fixedly connected to both ends of the connecting rod 25.

[0035] The hopper 11, solenoid valve 12, connecting pipe 13, liquid level sensor 17, and ink reservoir 4 are each equipped with two sets. The left set is the main ink supply component, and the right set is the backup ink supply component. During normal printing, the left main ink supply component is started first to supply ink. When the ink in the left ink supply component is used up, it is automatically switched to the right backup ink supply component and an alarm is issued to remind that the left ink supply component is low on ink. At this time, the operator can replace the left ink reservoir 4 without stopping the machine. When the right ink reservoir 4 is used up, it is automatically switched back to the left ink supply component, and then the right ink reservoir 4 is replaced.

[0036] The ink inside the ink reservoir 4 is discharged into the hopper 11 and then injected into the transfer cylinder 2 through the ink inlet pipe 21. When the ink in one ink reservoir 4 is used up, some ink will remain in the transfer cylinder 2. During the process of switching to the other ink supply component, the ink in the transfer cylinder 2 is continuously consumed until the solenoid valve 12 on the other side is opened. Then the ink in the other ink reservoir 4 continues to be replenished into the transfer cylinder 2, so that the transfer cylinder 2 always has ink, thereby achieving uninterrupted printing.

[0037] Furthermore, during the ink supply process, the electric motor 24 continuously drives the connecting rod 25 and the stirring rod 26 to rotate, slowly stirring the ink inside the transfer cylinder 2 to prevent ink from settling and clumping, ensuring smooth ink discharge, thus preventing clogging and ink interruption, and improving print quality and efficiency.

[0038] See Figures 2 to 4Two sets of feeding hoppers 11 are fixedly connected to the lower surface of the mounting plate 1. Solenoid valves 12 are fixedly installed at the lower end of the feeding hoppers 11. Connecting pipes 13 are fixedly connected to the upper surface of the mounting plate 1 at the position above the two sets of feeding hoppers 11. Liquid level sensors 17 are fixedly connected to the upper surface of the mounting plate 1 at the position on the side of the two sets of connecting pipes 13. A support frame 14 is fixedly connected to the inner wall of the connecting pipe 13. An ink guide cone 15 is fixedly connected to the center of the support frame 14. Multiple sets of ink guide grooves 16 are opened on the side of the ink guide cone 15. A connector 41 is fixedly connected to the lower end of the ink storage bottle 4. The connector 41 is threadedly connected to the connecting pipe 13. Sealing paper 42 is bonded to the lower end of the connecting pipe 13.

[0039] Specifically, during the installation of the ink reservoir 4, the connector 41 at the lower end of the ink reservoir 4 is inserted into the inner side of the connecting tube 13, making it threadedly connected to the connecting tube 13, and the ink reservoir 4 is tightly fixed to the upper side of the mounting plate 1. During the connection between the connector 41 and the connecting tube 13, the ink guide cone 15 will gradually pierce the sealing paper 42 and insert the ink guide cone 15 into the interior of the ink reservoir 4. At this time, the ink inside the ink reservoir 4 will flow into the interior of the feeding hopper 11 through the ink guide groove 16. At the same time, the liquid level sensor 17 monitors the ink inside the feeding hopper 11 in real time and transmits the monitoring information to the controller in real time.

[0040] See Figure 2 , Figure 5 and Figure 6 The lower ends of the two sets of solenoid valves 12 are fixedly connected to ink inlet pipes 21. The lower ends of the two sets of ink inlet pipes 21 are fixedly connected to the left and right sides of the intermediate drum 2, respectively. The upper end of the intermediate drum 2 is fixedly connected to two sets of exhaust pipes 22. The upper end of the exhaust pipes 22 is fixedly connected to the mounting plate 1. The ink discharge pipe 23 is fixedly connected to the lower end of the intermediate drum 2. The end of the ink discharge pipe 23 away from the intermediate drum 2 is fixedly connected to the ink inlet end of the ink supply pump 3. The ink outlet end of the ink supply pump 3 is fixedly connected to the ink supply pipe 31.

[0041] Meanwhile, when there is ink inside the hopper 11, the lower solenoid valve 12 is in the normally open state, and the other set of solenoid valves 12 is in the closed state. After the ink inside the hopper 11 is drained, the controller automatically closes the lower solenoid valve 12 and opens the other solenoid valve 12. The ink inside the hopper 11 enters the interior of the transfer cylinder 2 through the lower ink inlet pipe 21. Then, the ink supply pump 3 draws the ink inside the transfer cylinder 2 through the ink discharge pipe 23.

[0042] The working principle of this utility model is as follows: By utilizing two sets of ink storage bottles 4, a feeding hopper 11, a solenoid valve 12, a liquid level sensor 17, and a transfer cylinder 2, during operation, one set of solenoid valves 12 opens, allowing ink from the corresponding ink storage bottle 4 to flow into the transfer cylinder 2 through the feeding hopper 11. After the ink in the feeding hopper 11 is drained, the lower solenoid valve 12 closes, while the other solenoid valve 12 opens, allowing the other ink storage bottle 4 and feeding hopper 11 to supply ink. At this time, the depleted ink storage bottle 4 can be replaced, ensuring normal ink supply during replacement, enabling continuous printing, avoiding printing interruptions, and improving print quality and efficiency. Simultaneously, during ink supply, the electric motor 24 drives the connecting rod 25 to rotate, which in turn drives the stirring rod 26 to rotate, stirring the ink inside the transfer cylinder 2 and preventing ink sedimentation that could clog the ink discharge pipe 23, further improving print quality and efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
