Description

Technical Field

[0001] This utility model relates to an ink supply structure for printing equipment, belonging to the field of ink supply structure cleaning technology. Background Technology

[0002] When a flexographic printing press is in use, the ink take-up roller takes the corresponding color pigment from the ink supply tank and supplies it to the printing roller. When printing for different needs, the ink tank and doctor blade need to be cleaned to prevent the original pigment from affecting the normal use of printing. The traditional cleaning method is difficult to clean because the ink will adhere to the surface of the ink tank due to drying, curing and oxidation. It not only wastes water resources, but also has a very complicated operation. It requires soaking first and then cleaning with tools such as scrapers, which is time-consuming, labor-intensive and easy to cause incomplete cleaning. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ink supply structure for printing equipment, which simplifies the cleaning of the ink tank of the printing press. It can effectively clean the ink tank while simplifying the cleaning process and also helps to save water resources.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides an ink supply structure, including an ink supply tank, a driving device, and a cleaning mechanism. The ink supply tank has an opening structure at its upper part for receiving ink. A glue-dispensing roller is rotatably mounted on the opening of the ink supply tank. The interior of the ink supply tank is hollow, and the surface of the opening has multiple liquid outlet holes. A sealing plate is slidably mounted on the side of the ink supply tank, fitting against the bottom of the opening, and the sealing plate has openings corresponding to the multiple liquid outlet holes. The driving device drives the sealing plate to slide against the bottom of the ink supply tank opening. At least the surface of the opening of the ink supply tank is coated with Teflon material.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0025] This utility model provides an ink supply structure for printing equipment, which simplifies the cleaning of the ink tank of a printing press. It effectively cleans the ink tank while simplifying the cleaning process and conserving water resources. To achieve the structural function, the structure includes an ink supply tank 1, a drive device 4, and a cleaning mechanism. Specifically, the ink supply tank 1 has an ink-receiving opening at its upper part for storing a fixed amount of ink. A glue-dispensing roller 2 is rotatably mounted on the ink supply tank 1 at the opening, with the bottom of the glue-dispensing roller 2 being lower than the ink level. The height ensures that the ink dispensing roller 2 can supply ink during rotation. To facilitate cleaning, Teflon material is coated on at least the surface of the ink supply tank 1 at the opening. The non-stick properties of Teflon prevent ink from hardening and adhering to the material surface, which would hinder cleaning. Furthermore, to facilitate direct cleaning of the tank, the ink supply tank 1 is hollow inside, with multiple liquid outlet holes on the surface of the opening. A sealing plate 3 is slidably installed on the side of the ink supply tank 1, fitting against the bottom of the opening and sealing it. The sealing plate 3 has openings corresponding to multiple liquid outlet holes. A driving device 4 is configured to drive the sealing plate 3 to slide against the bottom of the ink supply tank 1. During the rotation of the sealing plate 3, the openings and liquid outlet holes can discharge the liquid in the tank. When the equipment is working normally, the openings of the sealing plate 3 and the liquid outlet holes on the tank opening are in a staggered position, creating a stable environment for storing liquid in the tank opening. During cleaning, the openings and liquid outlet holes correspond, allowing the cleaning liquid to be discharged directly from the tank opening space without the need for manual removal of the cleaning tank to empty the liquid, making the operation simpler. At this time, the cleaning mechanism is used to provide cleaning liquid to the ink supply tank 1. Preferably, a high-pressure spray action can be used to clean the ink residue in the tank. On the one hand, this avoids scratches, and on the other hand, the high-pressure action provides a more stable force to help remove the ink residue. In some preferred embodiments, a high-pressure water source can be configured to move at the surface of the tank opening to facilitate comprehensive cleaning. In order to ensure that the cleaning liquid can be discharged in time, a drain pipe 6 can be provided at the bottom of the ink supply tank 1 to connect to the cavity inside the ink supply tank 1, so as to prevent the cleaning liquid from accumulating. In this embodiment, the ink supply tank 1 is preferably made of stainless steel to provide a stable support structure. The thickness of the Teflon material is set between 15-20um to avoid material waste due to excessive material and excessive wear due to insufficient material, which would cause the anti-sticking effect to fail.

[0026] This utility model provides an ink supply structure for printing equipment. To ensure that the ink outlet and the opening can be accurately aligned or separated, the structure also includes a U-shaped frame 5 to ensure the accuracy of the movement position. In this case, the driving device 4 can be configured as a cylinder, and the output end of the cylinder and the sealing plate 3 are connected by a connecting piece. (See reference...) Figure 1As shown, by setting the connecting piece in the middle of the U-shaped frame 5, when the connecting piece abuts against the end of the U-shaped frame 5, it can prevent the connecting piece from moving further, thereby achieving precise positioning and avoiding the situation where the matching degree between the liquid outlet and the opening is smaller, resulting in a slower liquid flow rate and ink residue clogging, which is beneficial to improving control accuracy.

[0027] This utility model provides an ink supply structure for printing equipment, specifically a cleaning mechanism. The cleaning mechanism includes a mounting frame 7 and a liquid supply pipe 8 fixedly mounted on the mounting frame 7. To facilitate multi-directional spray cleaning, the liquid supply pipe 8 is equipped with multiple nozzles 9 facing the opening of the ink supply tank 1. When using water washing, liquid residue easily forms inside the tank opening. To facilitate the supply of new ink without affecting ink quality, air blowing can be used to quickly dry the water stains inside the tank opening. Specifically, to simplify the structure, the structure can also include two interconnecting pipes 14, as shown in the reference. Figure 1 As shown, a two-way connecting pipe 14 is connected to a liquid supply pipe 8, and a solenoid valve 15 is installed on both sides of the liquid outlet node of the two-way connecting pipe 14. At this time, one of the two solenoid valves 15 is used to control the supply of gas and the other is used to control the supply of cleaning liquid. The two valves cannot be opened at the same time. The gas or liquid is supplied by a set of nozzles 9, and the structural design is simpler.

[0028] In some embodiments of the ink supply structure for printing equipment provided by this utility model, in order to facilitate the removal of the cleaning structure and thus facilitate ink supply or other operations, mounting plates 10 can be provided on both sides of the ink supply tank 1, such as... Figure 1 and Figure 4 As shown, a connecting rod 11 is rotatably connected between the two mounting plates 10. The mounting bracket 7 is fixedly mounted on the connecting rod 11, allowing it to rotate with the rod. By changing the position of the connecting rod 11, the mounting bracket 7 can be opened at different locations to expose the slot. To ensure the mounting bracket 7 is stably positioned before and after opening, an L-shaped plate 12 can be provided on the connecting rod 11. Figure 4 As shown, the L-shaped plate 12 can abut against the top surface or side wall of the ink supply tank 1. Direct contact between the L-shaped plate 12 and the ink supply tank 1 avoids squeezing of other unnecessary parts, which helps ensure the stability of the structure during rotation. To prevent instability of the mounting bracket 7 due to reverse pressure during cleaning, a sliding piece 13 can be provided on the side wall of the ink supply tank 1. The sliding piece 13 is used to limit the side of the L-shaped plate 12 when it abuts against the top surface of the ink supply tank 1. Figure 1 As shown, the limiting action prevents the L-shaped plate 12 from falling off, thereby preventing the mounting bracket 7 from becoming unstable and flipping over.

[0029] This utility model provides an ink supply structure for printing equipment. In some embodiments, to avoid leakage caused by assembly errors between the ink supply tank 1 structure and the sealing plate 3 structure, an elastic layer 16 is provided on the bottom surface of the ink supply tank 1 opening structure to contact the sealing plate 3. Alternatively, an elastic ring 17 is provided on the inner side of each liquid outlet hole of the ink supply tank 1 to contact the surface of the sealing plate 3. The configuration of the elastic layer 16 or the elastic ring 17 with the sealing plate 3 achieves a good seal, thereby preventing liquid from leaking out from the assembly gap and effectively ensuring the good storage capacity of the opening.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
