Description

Technical Field

[0001] The utility model belongs to the technical field of pad printing machine oil cups, and in particular relates to a pad printing machine oil cup suitable for metal ink. Background Art

[0002] Pad printing machine is a printing equipment suitable for plastics, toys, glass, metal, ceramics, electronics, IC seals, etc. Pad printing is an indirect printing technology with a concave rubber head, and has become a major method for printing and decorating the surface of various objects;

[0003] The pad printing machine oil cup is an important component of the pad printing machine. For example, a pad printing machine oil cup with publication number: CN211222546U includes: a top cover, a tank body, a bushing and an ink scraper ring. The tank body has a first boss on the side facing the top cover, the top cover is connected to the top of the first boss, and the first boss has a through hole. The bushing includes a frustum-shaped fixed base, and the fixed base is provided with a second boss at one end facing the tank body. The second boss is adapted to the through hole, and a fixed protrusion is provided in an annular shape on the outer peripheral side of the second boss. The second boss is buckled with the slot of the through hole through the fixed protrusion. The bushing of the pad printing machine oil cup of the utility model is a cheap consumable made of plastic. When the ink needs to be replaced, it is only necessary to remove the ink scraper ring, and then replace the ink together with the bushing as a whole. It can effectively prevent the oil cup from being contaminated by ink, and omit the cleaning and maintenance of the bushing, thereby improving production efficiency.

[0004] The inventor believes that the magnets arranged on the existing pad printing machine oil cup are all designed to surround the inner side of the knife ring. If metal-containing ink is used in the pad printing operation, the knife ring will scrape off the ink on the etching plate, causing the magnets on the inner side of the knife ring to absorb and gather the magnetic metal in the ink, thereby causing the metal in the ink to be unevenly dispersed, ultimately affecting the pad printing quality and causing color difference. Figure 5 As shown;

[0005] In view of this, the utility model provides an ink cup for a pad printer suitable for metal ink to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a pad printing machine ink cup suitable for metallic ink, aiming to solve the problem of color difference caused by the prior art printing machine ink cup during pad printing operation containing metallic ink.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an oil cup for a pad printing machine suitable for metal ink, comprising an oil cup body, a knife groove is provided at the bottom of the oil cup body, a magnet groove is also provided at the bottom of the oil cup body, a magnet is embedded in the magnet groove, and the magnet groove surrounds the outside of the knife groove.

[0008] Preferably, as a pad printing oil cup applicable to metal ink of the present utility model, the outer wall of the top opening of the oil cup body is of a threaded structure.

[0009] Preferably, as a pad printing oil cup applicable to metal ink of the present utility model, a sealing ring is attached to the inner wall of the knife groove, and a knife ring is placed inside the sealing ring.

[0010] Preferably, as a pad printing oil cup applicable to metal ink of the present utility model, the cross-section of the sealing ring is in a "U" shape and is made of rubber material.

[0011] Preferably, as a pad printing oil cup applicable to metal ink of the present utility model, the knife ring is made of any one of ceramic or tungsten steel materials, and it is connected with an interference fit between the sealing ring and the knife groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, by arranging the magnet groove around the outside of the knife groove, the magnet embedded in the magnet groove will be arranged around the outside of the knife groove. When the knife ring scrapes the metal ink on the etching plate, the magnet will not adsorb and accumulate the magnetic metals in the metal ink, thus solving the problem of uneven distribution of metals in the metal ink caused by using the existing oil cup, effectively improving the pad printing quality of the metal ink and reducing color difference.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-Figure 4 , the present utility model provides the following technical solutions: A pad printing oil cup suitable for metal ink, including an oil cup body 1. The outer wall of the top opening of the oil cup body 1 is a threaded structure for connecting an oil cup cover. A knife groove 4 is opened at the bottom of the oil cup body 1. A magnet groove 2 is also opened at the bottom of the oil cup body 1. A magnet 3 is embedded in the magnet groove 2, and the magnet groove 2 surrounds the outside of the knife groove 4.

[0023] During specific use, the sealing ring 5 and the knife ring 6 are sequentially placed in the knife groove 4. Then, the metal ink is placed in the inner cavity of the oil cup body 1. After screwing on the oil cup cover at its top, it is installed in the gripper on the pad printing machine and clamped and fixed. During pad printing, since the ink containing metal is inside the knife ring 6, the magnet 3 located outside the knife ring 6 will not affect the metal ink inside the knife ring 6, effectively improving the pad printing operation quality of the metal ink.

[0024] Furthermore: In addition to being set as individual circular grooves, the magnet groove 2 can also be directly set as an annular groove, and the magnet 3 adapted to it is embedded in its interior, but it must be arranged around the outside of the knife groove 4. This can not only improve the pad printing operation quality of the metal ink, but also increase the contact area between the magnet 3 and the etching plate, improve the adsorption force between the magnet 3 and the etching plate, thereby further improving the sealing effect between the knife ring 6 and the etching plate and reducing the oil leakage situation.

[0025] Preferably: A sealing ring 5 is fitted on the inner wall of the knife groove 4. A knife ring 6 is placed inside the sealing ring 5. The cross-section of the sealing ring 5 is in a "U" shape and is made of rubber material. The knife ring 6 is made of any one of ceramic or tungsten steel materials, and it is connected with the knife groove 4 through an interference fit formed by the sealing ring 5.

[0026] During specific use, through the setting of the sealing ring 5, a soft connection can be formed between the knife ring 6 and the knife groove 4. When the knife ring 6 slides into contact with the etching plate, due to the deformability of the sealing ring 5, the knife ring 6 can always fit the etching plate, and the sealing effect is better.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
