Description

Technical Field

[0001] The utility model belongs to the technical field of pad printing machines, and in particular relates to an oil cup for a pad printing machine. 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] There are two types of pad printing machine ink cups: Figure 5 , Figure 7 As shown, one is an oil cup with an opening on the top, and the other is an integrated type with a threaded hole on the top, which are respectively used in two types of pad printing machines. These existing pad printing machine oil cups have the following shortcomings when used:

[0004] 1. The existing pad printer uses a hard connection between the oil cup and the knife ring, that is, the knife ring is directly placed on the boss at the bottom of the oil cup that matches the knife ring. When this connection method is installed on the pad printer, the pad printer needs to drive the oil cup to slide for a certain period of time to make the knife ring and the etched plate smooth before production operations can be carried out, otherwise oil leakage is likely to occur;

[0005] 2. If Figure 8 As shown, the outer edge of the knife ring needs to be flush with the outer edge of the oil cup boss, so that the clamp 9 on the pad printing machine can clamp the knife ring and the oil cup at the same time. Therefore, a thicker knife ring needs to be made, which increases production costs. Utility Model Content

[0006] The utility model aims to provide an oil cup for a pad printing machine, aiming to solve the problems in the prior art that the oil cup for a pad printing machine and a knife ring are hard-connected, which is prone to oil leakage, and the outer edge of the knife ring needs to be flush with the outer edge of the oil cup boss, which results in the knife ring being made thicker and increasing production costs.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: an oil cup for a pad printer, comprising an oil cup body, a magnet and a knife ring embedded in the bottom opening end of the oil cup body, an oil cup cover being threadedly connected to the top of the oil cup body, and a through hole being opened on the oil cup cover;

[0008] The bottom open end of the oil cup body is also provided with an annular groove, and a sealing ring is provided inside the annular groove. The sealing ring completely adheres to the inner wall of the annular groove. The knife ring is embedded in the annular groove through the sealing ring to form a soft connection between it and the oil cup body.

[0009] As a preferred embodiment of the pad printing machine oil cup of the utility model, the edge surface of the oil cup cover is printed with anti-slip patterns.

[0010] As a preferred embodiment of the pad printing machine oil cup of the utility model, the through hole is vertically opened at the center of the oil cup cover.

[0011] As a preferred embodiment of the pad printing machine oil cup of the utility model, the magnets are arranged in a ring shape with equal spacing.

[0012] As a preferred embodiment of the pad printing machine oil cup of the utility model, the inner wall of the through hole is a threaded structure.

[0013] As a preferred embodiment of the pad printing machine oil cup of the utility model, the sealing ring is made of rubber material.

[0014] As a preferred embodiment of the pad printing machine oil cup of the utility model, the knife ring is made of any one of tungsten steel material or zirconium oxide material.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides an annular groove at the bottom of the oil cup body and arranges a sealing ring in the annular groove, so that when the knife ring is assembled into the annular groove, a soft connection between the knife ring and the oil cup body can be achieved. Therefore, compared with the prior art, the knife ring can be tightly fitted with the etching plate at all times through the deformation of the sealing ring, so that oil leakage is not likely to occur, and there is no need to grind the knife ring and the etching plate in advance;

[0017] 2. Due to the opening of the annular groove, the clamp on the pad printing machine only needs to clamp the oil cup body. Therefore, there is no need to make the knife ring thicker, which effectively saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-3 The utility model provides the following technical solutions: an oil cup for a pad printing machine, comprising an oil cup body 1, a magnet 2 embedded in the bottom open end of the oil cup body 1, and a knife ring 5, wherein the knife ring 5 is made of either tungsten steel or zirconium oxide, the magnets 2 are arranged in a ring shape with equal spacing, the top of the oil cup body 1 is threadedly connected with an oil cup cover 6, the oil cup cover 6 is provided with a through hole 7, and the through hole 7 is vertically arranged at the center of the oil cup cover 6, so as to achieve better uniformity of force during power transmission of the pad printing machine, and the oil cup body 1 slides more smoothly;

[0030] When used specifically, if it is necessary to install it with a pad printer with a clamp 9, the oil cup body 1 can be directly clamped between the clamps 9 for use;

[0031] If it is necessary to install it with a pad printing machine with a connecting screw 8, the connecting screw 8 can be first inserted into the through hole 7 on the top of the oil cup cover 6, and then the oil cup body 1 and the oil cup cover 6 are threadedly connected after being locked and fixed with a fastener. The assembly is completed. Since it can be used on two different types of pad printing machines at the same time, it has stronger adaptability.

[0032] Furthermore, the inner wall of the through hole 7 may also be provided with a threaded structure, so that the through hole 7 can be directly threadedly connected with the connecting screw 8 to achieve assembly between the oil cup cover 6 and the connecting screw 8 .

[0033] An annular groove 3 is also provided at the bottom open end of the oil cup body 1, and a sealing ring 4 is provided inside the annular groove 3. The sealing ring 4 is made of rubber. The knife ring 5 is embedded in the annular groove 3 through the sealing ring 4, so that a soft connection is formed between it and the oil cup body 1. The edge surface of the oil cup cover 6 is printed with anti-slip patterns. The setting of the anti-slip patterns can facilitate the user to rotate the oil cup cover 6 to facilitate the disassembly of the oil cup cover 6 so as to facilitate assembly with different types of pad printing machines.

[0034] During specific use, before installing the knife ring 5, it is necessary to first insert the sealing ring 4 into the annular groove 3. Due to the deformable characteristics of the sealing ring 4, when the installed knife ring 5 is pressed on the etching plate and slides, the knife ring 5 can always fit and be flush with the surface of the etching plate, thereby effectively preventing oil leakage. At the same time, since the knife ring 5 only needs to be inside the annular groove 3, the knife ring 5 does not need to be made very thick and flush with the outer edge of the oil cup body 1, which effectively reduces the production cost.

[0035] 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.
