Description

Technical Field

[0001] The utility model relates to the field of digital printing equipment, and particularly to a digital printing equipment. Background Art

[0002] Digital printing equipment is an efficient printer used for directly printing on various surfaces, such as paper, plastic, metal, and fabric. It utilizes digital technology to control the print head through a computer and directly prints images or texts on the target material with high resolution. Compared with traditional printing methods, digital printing equipment features speed, flexibility, and precision, and is suitable for short-run printing and personalized customization, being widely applied in fields such as advertising, labeling, packaging, and product identification.

[0003] After retrieval, the Chinese patent "A Digital Printing Ink Supply Equipment" has the authorization announcement number "CN220562376U". This application discloses a digital printing ink supply equipment in the technical field of printing equipment. A digital printing ink supply equipment includes a printing box. There is a storage box at the bottom side of the inner cavity of the printing box, and an ink box is arranged above the storage box. A ink supply component is arranged between the ink box and the storage box. The ink supply component includes a pneumatic diaphragm pump. The pneumatic diaphragm pump is arranged above the storage box. There are delivery pipes connected between the input end of the pneumatic diaphragm pump and the storage box and between the output end of the pneumatic diaphragm pump and the output end of the ink box. A printing component and a detection component are arranged in the ink box. There are two elastic components at the upper side of the inner cavity of the printing box. A pressing roller is rotatably arranged between the two elastic components. There are openings on both sides of the printing box. When the ink liquid level in the ink box is relatively low, the detection component can activate the internal switch, thereby starting the ink supply component to add the ink in the storage box into the ink box for ink supply, eliminating the need for manual ink addition and saving labor.

[0004] Although the above digital printing equipment can achieve the effect of self-inking the printing roller through the ink supply component, the ink supply method of continuously contacting the printing roller with the ink not only increases the consumption of ink, but also immerses the printing roller in the ink, causing the ink to stain the recesses of the printed characters, which will affect the quality of subsequent digital printing. Moreover, it is prone to excessive printing humidity due to too much ink, resulting in printing blurring or ghosting.

[0005] Therefore, a digital printing equipment is proposed to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a digital printing equipment to solve the above problems, improving the problems that the traditional digital printing device cannot supply ink by itself and the ink supply amount cannot be accurately controlled, which is likely to affect the printing quality.

[0007] The present utility model achieves the above object through the following technical solutions. A digital printing device includes: a bottom plate, on the surface of which there are vertical rods. The number of the vertical rods is four.

[0010] Preferably, a sliding rod is slidably connected inside the cavity of the movable shell. By cooperating with the piston through the sliding rod, the pressure inside the movable shell can be changed, so that the movable shell can extract and discharge the ink. On the surface of the sliding rod, there is a piston. The side of the sliding rod close to the movable plate is fixedly connected with the movable plate, and the top of the piston contacts the contact block.

[0011] Preferably, on one side inside the cavity of the movable shell, there is a fixed connection with a column. Through the column, the position where the piston descends can be controlled to achieve the effect of quantitatively extracting ink. The number of the columns is two, and the side of the column close to the piston corresponds to the piston.

[0012] Preferably, both the feeding end and the discharging end of the ink inlet pipe are communicated with a sealing shell.

[0015] Preferably, a resistance increasing ring is arranged inside the cavity of the piston. The resistance increasing ring is located inside the cavity of the piston, and its function is to increase the resistance between the piston and the sliding rod when the sliding rod rises. The inner cavity of the resistance increasing ring contacts the sliding rod.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Through the quantitative ink supply component, each time the cylinder drives the movable plate and the printing plate on its surface to press down, it can automatically extract ink from the ink tank and press the ink into the printing plate through pressure after the printing plate has finished printing, achieving a self - contained and quantitative ink injection process, which can effectively save the manpower and time consumed by manual ink addition.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] During specific implementation: As Figures 1-5As shown, a digital printing device includes: a bottom plate 1, on the surface of the bottom plate 1, there are upright rods 2, the number of the upright rods 2 is four, between the tops of the four upright rods 2, there is a fixed connection with a top plate 4, between the surfaces of the four upright rods 2, there is a sliding connection with a movable plate 3, on the surface of the movable plate 3, there is a fixed connection with a printing plate 8, on the surface of the bottom plate 1, there is a fixed connection with a bearing plate 7, in the inner cavity of the top plate 4, there is a fixed connection with a cylinder 5, and the telescopic end of the cylinder 5 is fixedly connected to the movable plate 3;

[0027] A quantitative ink supply assembly 6 is arranged between the movable plate 3 and the top plate 4.

[0028] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in, the quantitative ink supply assembly 6 includes a movable shell 601 arranged between the movable plate 3 and the top plate 4. On the surface of the movable shell 601, there are respectively communicated pipes for ink inlet and ink supply. Among them, the feeding end of the ink inlet pipe is communicated with an ink tank 606, and the discharging end of the ink supply pipe is communicated with the printing plate 8. In the inner cavity of the movable shell 601, there is a fixed connection with a contact block 611; in the inner cavity of the movable shell 601, there is a sliding connection with a sliding rod 604. On the surface of the sliding rod 604, there is a piston 602. The side of the sliding rod 604 close to the movable plate 3 is fixedly connected to the movable plate 3, and the top of the piston 602 contacts the contact block 611; on one side of the inner cavity of the movable shell 601, there is a fixed connection with a column 603, the number of the columns 603 is two, and the side of the column 603 close to the piston 602 corresponds to the piston 602; both the feeding end and the discharging end of the ink inlet pipe are communicated with a sealing shell 607. In the inner cavities of the two sealing shells 607, there are one-way valves 608 respectively, and the valve openings of the two one-way valves 608 are arranged in opposite directions; on the side of the surface of the movable shell 601 close to the top plate 4, there is a fixed connection with a positioning shell 605, and the side of the positioning shell 605 close to the top plate 4 is fixedly connected to the top plate 4; on the surface of the piston 602, there are two sealing rings 609 sleeved, and the surface of the sealing rings 609 contacts the inner wall of the movable shell 601; in the inner cavity of the piston 602, there is an increased resistance ring 610, and the inner cavity of the increased resistance ring 610 contacts the sliding rod 604.

[0029] A column 603 is arranged at the bottom of the inner cavity of the movable shell 601, and the height of the column 603 is equal to one third of the inner cavity space of the movable shell 601, which means that the piston 602 can only descend to the height of the rod 2 when following the slide rod 604 to descend, and the inner cavity of the piston 602 is provided with a resistance increasing ring 610, and the resistance support point of the resistance increasing ring 610 is downward. After the slide rod 604 moves down to a certain position, the bottom of the piston 602 will be limited by the column 603, and then when the slide rod 604 rises, the resistance increasing ring 610 inside the piston 602 will be stretched and move up with the slide rod 604, and the movable range of the piston 602 is limited between the abutment block 611 and the column 603. Therefore, the amount of ink extracted and discharged each time is controlled to a specified value, so as to achieve the effect of quantitative ink supply.

[0030] The one-way valve 608 is arranged between the two sealing shells 607 and is located at the feed end and the discharge end of the ink inlet pipe. The valve ports of the two one-way valves 608 are arranged oppositely. When the piston 602 is squeezed upward, the one-way valve 608 at the discharge port of the ink inlet pipe will close automatically due to air pressure, thereby preventing the ink from flowing back.

[0031] It should be noted that after the ink enters the interior of the printing plate 8, the ink enters the distribution pipe inside the plate. The printing plate 8 is provided with precisely designed flow pipes, which can ensure that the ink flows evenly in various areas of the printing plate 8. The design of the printing plate 8 usually includes small channels or holes, so that the ink can be evenly diffused in the layout, thereby achieving uniform distribution of the ink, which is conducive to printing.

[0032] First, the cylinder 5 drives the printing plate 8 to be pressed down through the movable plate 3. When the movable plate 3 moves downward, the slide rod 604 will drive the piston 602 to move downward accordingly. When the piston 602 moves downward, a negative pressure will be formed inside the movable shell 601. At this time, the ink in the ink box 606 is drawn into the inside of the movable shell 601 by pressure and placed on the surface of the piston 602. When printing is completed, the piston 602 will rise again with the slide rod 604 to inject the ink into the inside of the printing plate 8 through the ink delivery pipe, thereby achieving the effect of self-delivery of ink.

[0033] When the utility model is in use, when the staff needs to perform printing on printed matter, first add ink to the ink tank 606, and then place the printed matter to be printed on the bearing plate 7. At this time, the air cylinder 5 can drive the printing plate 8 to press down through the movable plate 3. When the movable plate 3 moves downward, the sliding rod 604 will drive the piston 602 to move downward accordingly. When the piston 602 moves downward, a negative pressure will be formed inside the movable shell 601. At this time, the ink in the ink tank 606 will be sucked into the inside of the movable shell 601 through pressure and placed on the surface of the piston 602. When the printing is completed, the piston 602 will rise again following the sliding rod 604 to inject the ink into the printing plate 8 through the ink supply pipeline, achieving the effect of self-inking, which can effectively save the manpower and time consumed by self-inking.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
