Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, in particular to an ink feeding device of a printing machine. Background Art

[0002] Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places with text and images on the printing plate by hand or by the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating the same printed product as the printing plate.

[0003] The existing authorization announcement number is CN209534435U, which discloses an ink supply device for a printing press, including an ink cartridge arranged below an ink roller, an ink inlet opening at the bottom of the ink cartridge, an ink cartridge connected to an ink barrel via an oil delivery pipe, an oil delivery pump arranged on the oil delivery pipe between the ink cartridge and the ink barrel, and a baffle connected to the bottom of the ink cartridge via a support rod, the baffle being located directly above the ink inlet; the technical effect is: the output ink is sprayed onto the baffle and slowly spreads in the ink cartridge, reducing the possibility of ink splashing out of the ink cartridge. However, the ink supply device for the above-mentioned printing press cannot automatically add ink, and the ink needs to be added when it is used up during the adding process, and is closed when it is almost full. Such a cycle is relatively cumbersome, and the ink is easily precipitated during the storage process in the oil barrel, which affects the stability during the later printing process. Therefore, it is necessary to provide an ink supply device for a printing press to solve the above-mentioned problems. Utility Model Content

[0004] The technical content of the utility model is to provide an ink feeding device of a printing press.

[0005] In order to solve the above problems, the utility model provides an ink feeding device of a printing press, comprising: a base, an oil barrel is fixedly connected to the top of the base, a connecting pipe is fixedly connected to the outside of the oil barrel, and an ink cartridge is fixedly connected to the right end of the connecting pipe; an automatic component, the automatic component comprises a fixed frame, and the fixed frame is fixedly connected to the outside of the ink cartridge. First, the device is placed in a suitable position. When the ink level inside the ink cartridge is low, the reset spring contracts and the synchronous sliding rod of the conductive block slides downward inside the sleeve, so that the conductive block contacts the positive electrode sheet and the negative electrode sheet. At this time, the solenoid valve opens the pump body to start working, so that the ink inside the oil barrel enters the inside of the ink cartridge through the connecting pipe. When a certain amount of ink is added, the float rises and the reset spring is extended. The synchronous sliding rod of the conductive block slides upward inside the sleeve, so that the conductive block is disconnected from the positive electrode sheet and the negative electrode sheet and is powered off. At this time, the solenoid valve is closed and the pump body stops working, completing the process of automatically adding ink. During the process of adding ink, the stirring motor works synchronously, so that the stirring motor drives the stirring rod to rotate, and the stirring rod stirs the ink inside the oil barrel to avoid precipitation affecting the printing effect.

[0006] As a further solution of the utility model, the automatic component also includes a solenoid valve and a pump body, which are fixedly connected to the inside of the connecting pipe. When the solenoid valve and the pump body are opened at the same time, the ink inside the oil barrel can be drawn out and enter the inside of the ink cartridge through the connecting pipe.

[0007] As a further solution of the utility model, two sleeves, a positive electrode sheet and a negative electrode sheet are fixedly connected inside the bottom end of the fixed frame. The positive electrode sheet and the negative electrode sheet are located in the middle position of the two sleeves. The positive electrode sheet and the negative electrode sheet are linearly connected to the solenoid valve and the pump body.

[0008] As a further solution of the utility model, the interior of the two sleeves are slidably connected with a sliding rod, and the bottom of the sliding rod is fixedly connected with a conductive block. When the conductive block contacts the positive electrode sheet and the negative electrode sheet, the circuit of the solenoid valve and the pump body is connected, so that the pump body can draw out the ink inside the oil barrel and enter the interior of the ink cartridge through the connecting pipe.

[0009] As a further solution of the utility model, the tops of the two sliding rods are fixedly connected with a connecting rod, and the bottom of the connecting rod is fixedly connected with a floating ball. When there is too much ink in the ink cartridge, the floating ball will float up.

[0010] As a further solution of the utility model, the bottom ends of the two sleeves are fixedly connected with return springs, and the return springs are fixedly connected to the bottom of the sliding rod. The elastic force of the return springs can always keep the conductive block in contact with the positive electrode sheet and the negative electrode sheet, ensuring that when the ink level inside the ink cartridge is low, continuous filling is possible with strong flexibility.

[0011] As a further solution of the present invention, a cavity is opened inside the base, a stirring motor is fixedly connected to the bottom end of the cavity, a stirring rod is fixedly connected to one end of the stirring motor output shaft, and the stirring rod extends to the inside of the oil drum.

[0012] As a further solution of the present invention, a control panel is fixedly connected to the outside of the base, and four bottom columns are fixedly connected to the bottom of the base, and the bottom columns can stably support the entire device.

[0013] In summary, the present invention includes at least the following beneficial technical effects:

[0014] First, the utility model records that the device is first placed in a suitable position. When the ink level inside the ink cartridge is low, the reset spring contracts and the conductive block synchronous slide rod slides downward inside the sleeve, so that the conductive block contacts the positive electrode and the negative electrode. At this time, the solenoid valve opens the pump body to start working, so that the ink inside the oil barrel enters the ink cartridge through the connecting pipe. When the ink is added to a certain amount, the float rises and the reset spring extends. The conductive block synchronous slide rod slides upward inside the sleeve, so that the conductive block is disconnected from the positive electrode and the negative electrode and the power is cut off. At this time, the solenoid valve is closed and the pump body stops working, completing the process of automatically adding ink.

[0015] Second, the utility model records an ink supply device of a printing press, which records that during the process of adding ink, a stirring motor operates synchronously, so that the stirring motor drives a stirring rod to rotate, and the stirring rod stirs the ink inside the oil barrel to avoid precipitation that affects the printing effect.

First, the device is placed in a suitable position. When the ink level inside the ink cartridge 4 is low, the return spring 8 contracts and the conductive block 18 synchronously slides the sliding rod 17 downward inside the sleeve 16, so that the conductive block 18 contacts the positive electrode sheet 19 and the negative electrode sheet 20. At this time, the solenoid valve 7 opens the pump body 9 to start working, so that The ink inside the oil barrel 2 enters the ink cartridge 4 through the connecting tube 3. When a certain amount of ink is added, the float 13 rises and the reset spring 8 is extended. The conductive block 18 and the synchronous slide rod 17 slide upward inside the sleeve 16, so that the conductive block 18 is disconnected from the positive electrode 19 and the negative electrode 20 and the power is cut off.
