Abstract

A mechanism suitable for performing ink control for a roller stamping machine, the mechanism comprising an ink box lower housing (507), an ink box upper housing (504), an ink applying wheel assembly, an ink wiping wheel assembly, an ink printing wheel assembly and a torsion spring (508). The ink applying wheel assembly comprises a sponge rotating shaft (503), a sponge wheel fixing support (502) and a rubber wheel (506); the ink wiping wheel assembly comprises a sponge rotating shaft (503), an ink wiping wheel (505), a retaining ring, a clamping ring and a bearing (509); and the ink printing wheel assembly comprises an ink printing wheel (501), a sponge wheel fixing support (502) and a sponge rotating shaft (503). The ink applying wheel assembly is installed in a sliding groove on a side surface of the ink box lower housing (507), and the ink printing wheel assembly is pushed up into a sliding groove of the ink box upper shell (504) by means of the torsion spring (508). The ink wiping wheel is installed in a sliding grooves on a side rear surface of the ink box lower housing (507). Once the ink box upper housing(504) is covered, a pressing column of the ink box upper housing (504) presses the ink wiping wheel assembly against the ink applying wheel assembly, thereby achieving the effect of rotating to apply ink evenly. The described mechanism ensures that the ink on a stamp is even and the amount of ink is appropriate; in addition, the structure is simple, ink control is accurate, and the stamping effect is good.

Description

A mechanism suitable for ink control of roller stamping machine

Technical field

The utility model relates to the field of seal ink control.

Background technique

At present, the refueling method and seal oiling method of the roller stamping machine on the market have many defects. The refueling is inconvenient, the number of refueling and the amount of refueling cannot be controlled. When the stamp is printed with a lot of ink, the stamp will be spent, and the ink is wasted seriously and once. Refueling will not cover many chapters. The mechanism is designed to be convenient for users to operate, and the number of operations is significantly reduced.

Summary of the invention

The purpose of the present invention is to provide a mechanism for ink control of roller stamping machine with simple structure, less number of ink refills, uniform ink when the machine is working continuously for a long time, and complete stamps without deformation, aiming at the disadvantages of the prior art. The user feels convenient and simple.

To solve the above technical problems, a technical solution adopted by the present invention is: a mechanism for ink control of a roller stamping machine, including a stamp roller, a stamp mounting assembly, an oil box and a base. The seal roller and the rubber wheel on the seal mounting assembly on the one hand complete the task of picking up paper, on the other hand, when the paper reaches the stamping position, the seal installed on the seal mounting assembly (convex and concave, with the stamp on the convex surface) ) Rotates, and the stamp roller is relatively stationary at the place where it is squeezed to complete the stamping task; the stamp drives the ink cotton in the oil box assembly to press and rotate during the stamping process, on the one hand, the stamp is evenly oiled, on the other hand The ink pad drives the oil tanker to rotate, and transfers the controlled amount of ink in the oil tank or on the oil tanker to the ink oil pad; in the process of ink transfer, the oil oil pad is closely attached to the oil tanker and rotates with the oil tanker. The ink volume can be precisely controlled; when the stamp leaves the ink pad, the ink pad bounces under the action of the torsion spring, so that the opening can be blocked to reduce ink volatilization. The ink cartridge is fixed on the base by sliding grooves and screws.

The oil control system is based on the mutual squeezing and rotation of the oil tanker and the oil wiper.

The oil tanker assembly, the oil wiper assembly and the oil tanker assembly are all installed in the chute of the oil tank, and the lower shell under the oil tanker is slotted to ensure that all the ink is used.

The material of the tanker is hard and does not absorb oil, and the oiler and the tanker are made of sponge material.

Description of the drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings needed in the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative work, other drawings can be obtained based on these drawings, among which:

Figure 1 is a structural diagram of a preferred embodiment of the present invention;

Figure 2 is a structural diagram of a preferred embodiment of the ink cartridge of the present invention.

Figure 3 is an introduction diagram of the key features of the upper and lower shell parts of the oil box of the present invention.

Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

As shown in Figure 1 & Figure 2, the embodiments of the present invention include:

A mechanism suitable for ink control of a roller stamping machine. The ink cartridge mechanism includes an oil box lower shell 507, an oil box upper shell 504, an upper oiler assembly, an oil wiper assembly, an inkjet roller assembly and a torsion spring 508. The oil tanker assembly includes a sponge shaft 503, a sponge wheel fixing bracket 502, and a rubber wheel 506; the oil wiper assembly includes a sponge shaft 503, an oil wiper 505, a retaining ring, a clamp ring and a bearing 509; the oil tanker includes An ink tanker 501, a sponge wheel fixing bracket 502, and a sponge shaft 503. The upper tanker assembly is installed in the chute on the side of the lower oil tank shell 507 through the torsion spring 508 to lift the tanker assembly into the chute of the upper tank 504, and the oil wiper is installed on the side of the lower tank 507 In the rear chute, when the upper shell 504 of the oil box is covered, the pressure column of the upper shell 504 of the oil box presses the oil wiper assembly on the upper oiler assembly, thereby achieving the effect of uniform rotation and oiling. The present invention provides a mechanism suitable for the ink control of a roller stamping machine. Through the above mechanism, when the stamp roller 1 rotates and forms a squeeze with the rubber covering wheel 2 to drive the paper to be transported. After reaching the stamping position, the stamp motor drives the stamp 4 to rotate The seal 4 drives the oil tanker assembly installed on the upper oil box of the base 6 to rotate and press down, thereby driving the upper oiler assembly to rotate and bring the oil at the bottom of the oil tank up. After the oiler assembly, the ink on the belt is small and even. In this way, it is ensured that the ink on the ink tanker is uniform and suitable for each stamp, so that the ink on the ink tanker components can increase slowly and appropriately. The structure is simple, the ink is uniform and the stamp is complete when the machine is continuously working for a long time. Not deformed.

In summary, the present invention can achieve the purposes of simple fueling, accurate fuel control, excellent continuous stamping effect, and increased stamping times.

The above are only the embodiments of the present invention and do not limit the scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the present invention description, or directly or indirectly applied to other related technical fields, are all The same reason is included in the scope of patent protection of the present invention.
