Description

Technical Field

[0001] The utility model belongs to the technical field of the oil cup of a pad printer, and particularly relates to an oil cup of a pad printer for preventing oil leakage. Background Art

[0002] A pad printer is a printing device applicable to plastics, toys, glass, metal, ceramics, electronics, IC encapsulation, etc. Pad printing is an indirect concave rubber head printing technology and has become a main method for printing and decorating the surfaces of various objects.

[0003] The oil cup of a pad printer is an important component on the pad printer. For example, an oil cup of a pad printer with the publication number of CN211222546U includes: a top cover, a tank body, a bushing and a doctor blade ring. One side of the tank body facing the top cover has a first boss, and the top cover is connected to the top end of the first boss. The first boss has a through hole. The bushing includes a frustum-shaped fixed base. One end of the fixed base facing the tank body is provided with a second boss, and the second boss is adapted to the through hole. A fixed convex block is annularly arranged on the outer peripheral side of the second boss, and the second boss is buckled with the clamping groove of the through hole through the fixed convex block. The bushing of the oil cup of the utility model is a cheap consumable made of plastic material. When the ink needs to be replaced, only the doctor blade ring needs to be removed, and then the ink and the bushing are replaced as a whole, which can effectively avoid the oil cup being soiled by the ink and omit the cleaning and maintenance work of the bushing, thereby improving the production efficiency.

[0004] The inventor believes that most of the existing oil cups use a single-ring doctor blade to scrape off the ink, so that the ink is always stored in the annular space formed by the doctor blade ring. However, the protection effect of the single-ring doctor blade is not ideal. As long as the single-ring doctor blade is damaged during use, it will cause the leakage of the ink, thereby affecting the stable operation of the pad printer.

[0005] In view of this, the utility model provides an oil cup of a pad printer for preventing oil leakage to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an oil cup of a pad printer for preventing oil leakage, aiming at solving the problem that most of the existing oil cups of pad printers use a single-ring doctor blade arrangement. If the single-ring doctor blade is damaged during use, it will cause the leakage of the ink, thereby affecting the stable operation of the pad printer.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an oil cup of a pad printer for preventing oil leakage, including an oil cup main body. An annular doctor blade groove is formed on the surface of the open end at the bottom of the oil cup main body. A sealing ring is attached to the inner wall of the doctor blade groove. A doctor blade ring is placed inside the sealing ring. The doctor blade ring is connected with an interference fit between the sealing ring and the doctor blade groove. At least two groups of doctor blade grooves are formed, and each group of doctor blade grooves is sequentially sleeved around.

[0009] Preferably, as an oil cup of a pad printer for preventing oil leakage according to the present utility model, the oil cup cover is threadedly connected to the oil cup body.

[0010] Preferably, as an oil cup of a pad printer for preventing oil leakage according to the present utility model, a magnet groove is further formed on the surface of the open end at the bottom of the oil cup body, and a magnet is embedded in the magnet groove.

[0011] Preferably, as an oil cup of a pad printer for preventing oil leakage according to the present utility model, the magnet grooves are arranged in an equally spaced circular pattern, and the magnet grooves are located in the circular space of the knife groove.

[0012] Preferably, as an oil cup of a pad printer for preventing oil leakage according to the present utility model, a through hole is formed at the center of the oil cup cover.

[0013] Preferably, as an oil cup of a pad printer for preventing oil leakage according to the present utility model, a threaded structure is provided on the inner wall of the through hole.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By forming a plurality of knife grooves on the surface of the open end at the bottom of the oil cup body, the present utility model enables multiple sets of knife rings to be installed, forming a multi-layer ink surrounding circle. When the inner knife ring is damaged, the outer knife ring can still ensure that the ink is stored within the knife ring, thus effectively preventing ink leakage and providing a good foundation for the efficient and stable operation of the pad printer.

[0023] 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 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.

[0024] Please refer to Figures 1-3 , the present utility model provides the following technical solutions: An anti-oil leakage pad printer ink cup, including an ink cup main body 1. A magnet groove 2 is further opened on the surface of the bottom opening end of the ink cup main body 1. A magnet 3 is embedded in the magnet groove 2. The magnet 3 can be magnetically adsorbed with the printing etching plate of the pad printer, thereby further improving the fitting and sealing degree between the blade ring 6 and the printing etching plate. The magnet grooves 2 are arranged in an equally spaced annular pattern, and the magnet grooves 2 are located in the annular space of the blade groove 4. An annular blade groove 4 is opened on the surface of the bottom opening end of the ink cup main body 1. A sealing ring 5 is fitted on the inner wall of the blade groove 4. A blade ring 6 is placed inside the sealing ring 5. The blade ring 6 is connected with an interference fit between the sealing ring 5 and the blade groove 4. Through the setting of the sealing ring 5, a soft connection is formed between the blade ring 6 and the ink cup main body 1, thereby using the deformation force of the sealing ring 5 to further fit the blade ring 6 with the printing etching plate. At least two groups of blade grooves 4 are opened, and each group of blade grooves 4 is sequentially sleeved around. The top of the ink cup main body 1 is also threadedly connected with an ink cup cover 7.

[0025] During specific use, the blade ring 6 is connected into the blade groove 4 to form a multi-layer surrounding sleeve between the blade rings 6, forming a multi-layer protection circle for the ink. When the ink cup slides back and forth on the printing etching plate to scrape the ink, the formed multi-layer protection circle can well prevent the leakage of the ink, thereby improving the stability of the operation of the pad printer.

[0026] In order to enable this ink cup to cooperate with pad printers of different models, a threaded through hole can be opened at the center of the ink cup cover 7. The opened threaded through hole can be connected to a pad printer without a clamping mechanism, that is: using the through hole to threadedly connect the ink cup cover 7 with the ink cup connecting bolt of the pad printer, and then threadedly connecting the ink cup main body 1 with the ink cup cover 7, the installation and fixation between this ink cup and a pad printer without a clamping mechanism can be realized; while for a pad printer with a clamping mechanism, only need to use its clamping mechanism to clamp the outside of the ink cup main body 1 for clamping operation, as Figures 4-5 shown.
