Variable dot matrix seal

Technical Field

The invention relates to the technical field of seals, in particular to a variable dot matrix seal

Background

Two-dimensional codes are also called QR codes, and QR is called Quick Response, which is an ultra-popular coding mode on mobile equipment in recent years, and can store more information and represent more data types than traditional Bar Code Bar codes. The two-dimensional bar code/two-dimensional code (2-dimensional bar code) records data symbol information by using black and white alternate graphs which are distributed on a plane (two-dimensional direction) according to a certain rule by using a certain specific geometric figure; the concept of "0" and "1" bit stream forming the internal logic basis of computer is used ingeniously in coding, several geometric forms correspondent to binary system are used to represent literal numerical information, and can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing. Therefore, the two-dimensional code carries different information and presents different dot matrix images.

At present, the application of the two-dimensional code relates to various fields such as e-commerce, logistics, forms and the like. An invention patent with an authorization notice number of CN109291667A and an authorization notice date of 2019, 2, 1 and discloses a two-dimensional code stamp. The driving circuit can drive/not drive the imaging unit in the seal head lattice structure to output imaging materials through each electromechanical conversion unit of the electromechanical conversion part, thereby realizing that the lattice seal content can be adjusted without manual intervention. The scheme has the advantages of difficult lattice adjustment and higher cost, and can not be applied to the transportation and the process of pork and other foods.

Disclosure of Invention

The invention aims to provide a seal capable of stamping dot matrix images on pork, which can realize stamping by using edible ink, and comprises:

the stamp head comprises a metal cylinder provided with a circular lattice hole;

the seal cover plate comprises a plurality of cover plates which are nested with each other and can rotate independently, and holes are formed at the bottom of the seal cover plate;

the pop-up printing pin structure comprises a steel ball, a printing pin and a spring;

the relative position of the seal cover plate is changed by rotation, and the holes of the seal cover plate are aligned to different hole positions of the seal body, so that the printing needle is bounced, and the dot matrix image is changed.

Among the above-mentioned technical scheme, seal head dot matrix hole and bounce formula seal pin structure one-to-one, three nested seal apron each other can independently rotate, and it has the hole to open on the apron to make the hole aim at the steel ball of bounce formula seal pin structure, thereby make the seal pin bounce, thereby realize the controllable change of seal dot matrix.

As a further improvement of the invention, the pins of the variable dot matrix stamp are arranged in a circle, and the pins of the variable dot matrix stamp are arranged in a plurality of concentric circles.

As a further improvement of the invention, the seal cover plate of the variable dot matrix seal is of a plurality of mutually nested structures, and each circle of seal cover plate respectively corresponds to a circle of seal holes on the seal main body.

As a further improvement of the invention, the seal cover plate of the variable dot matrix seal is provided with holes, and the holes can be used for embedding steel balls of the bouncing seal structure, thereby realizing the accurate correspondence of the holes and the seal pins.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings

The present embodiment is only for explaining the present invention, and it is not limited to the invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as needed after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

The present invention provides a stamp capable of changing the dot matrix arrangement by a simple manual operation as shown in fig. 7. The stamp comprises a stamp main body as shown in figure 1, a stamp cover plate as shown in figure 4, and a bouncing type stamp pin structure inside the stamp main body as shown in figure 3.

The structure of the seal is as shown in figure 7, the seal cover plate is combined with a seal main body (1) through a screw in figure 4, the seal cover plate can rotate, a plurality of holes (24) are formed in the seal cover plate, after the holes rotate and are aligned with certain dot matrix holes (11), steel balls (131) of the bouncing type printing needle structure (13) shown in figure 3 in the dot matrix holes can be embedded into a groove, a spring (132) can bounce the printing needle (132), the printing needle retracts, no image is formed when the printing needle is stamped, and therefore the dot matrix is changed. And the cover plate is continuously rotated, the steel balls are pushed out from the holes of the seal cover plate, the corresponding printing needle bounces, and a printing point can be left during stamping.

As shown in FIG. 4 and FIG. 5, the seal cover plates are nested one within the other, with the inner seal cover plate higher than the outer seal cover plate, and the outer seal cover plate extending outwardly to press against the outer seal cover plate. As shown in fig. 5 and 6, fig. 5 is a cross-sectional view of the seal cover plate, fig. 6 is an image of the combined surface of the seal cover plate and the main body, a plurality of holes (24) are formed in all three seal cover plates, and the holes in the circular cover plate correspond to certain lattice holes in the seal main body.

The bounce type printing needle structure is shown in figure 3, the structure is placed in a dot matrix hole (11) of a main body (1), the structure consists of three parts, namely a steel ball (131), a printing needle (132) and a spring (133), the spring is always in a compression state and provides an upward driving force for the printing needle, so that the printing needle has a bounce tendency, when a hole (24) of a seal cover plate (2) is aligned with a certain dot matrix hole (11), the steel ball (131) in the dot matrix hole is pushed out upwards and is embedded into a groove, meanwhile, the printing needle (132) is pushed out upwards, and the seal dot matrix is changed.

In specific use, the user makes the seal apron change with the position relation of main part through rotatory seal apron, thereby makes some dot matrix holes of the hole alignment main part on the seal apron, thereby makes the steel ball embedding seal apron of the formula of bounceing seal pin structure in the dot matrix hole in, the steel ball upward movement back, the seal pin loses pressure, upwards pushed up by the spring, the seal pin upward movement, in the retraction seal pinhole, when the seal, this seal pin just can not leave the trace on being stamped the object, thereby realized the dot matrix and changed.
