Description

Bar printer with simple paper tearing structure

Technical Field

The utility model belongs to the printer field, in particular to bar printer who has simple and easy paper structure that tears.

Background

Bar code printer is often used in places such as hospital, commodity circulation, asset management, and bar code printing needs the slip sheet of the label paper that uses tougher, is difficult to tear, often appears tearing the problem of warping or tearing badly, to the occasion that often needs to tear the label such as hospital etc. the ubiquitous condition of tearing the not enough convenient and fast of label. In order to facilitate paper tearing, some users use additional scissors, and cut off the label with the scissors after printing the label, or purchase expensive paper cutter accessories to be matched with a printer for use, so that the time cost and the equipment cost are increased.

At present, bar code printer on the market is provided with the structure of tearing paper to this demand of tearing paper, and the structure of tearing paper sets up near printer exit slot and tears the scraps of paper for tear paper. The prior art discloses a paper tearing structure of a bar code printer, which comprises a main frame lower shell, wherein a carbon ribbon bracket is hinged on a center frame of the main frame lower shell, a paper feeding rubber roller is installed on the main frame lower shell, a turnover plate is arranged below the paper feeding rubber roller, a detachable paper tearing knife is installed at the edge of the main frame lower shell, the paper tearing knife is suspended above the edge of the turnover plate to form a paper outlet between the paper feeding rubber roller and the turnover plate, and a cutting edge is arranged at the edge of the paper tearing knife; after the data printing is finished, the label paper is upwards lifted facing the cutting edge at the edge of the paper tearing knife, and then the paper tearing can be finished. However, the paper tearing knife increases the cost of the printer equipment, and the paper tearing knife has certain danger, so that the paper tearing structure is not simple, safe and convenient enough.

Disclosure of Invention

In order to solve the problem, the utility model aims to provide a simple structure, with low costs have bar printer of simply tearing paper structure.

Another object of the utility model is to provide an economical and practical, easy batch production have the bar code printer of simply tearing the paper structure.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a bar printer that has simple and easy paper structure that tears, includes printer main part, top cap, casing, and the casing parcel printer main part that top cap and casing are constituteed, and the corresponding border position of top cap, casing encloses to close and forms the exit slot, and printer main part includes paper feed rubber roll and core, and paper feed rubber roll and core laminating form out the paper passageway, and one side that the casing is close to the exit slot sets up integrated into one piece and has the sawtooth. The paper tearing function is realized by arranging the sawteeth on the printer shell, paper tearing structures such as metal blades are not required to be specially added, the economic cost is reduced, the structure is simple, batch production is easy, and the paper tearing device is widely applied.

Furthermore, a plurality of sharp teeth are arranged on one side of the casing close to the paper outlet, and the sharp teeth are combined to form the saw teeth. The paper tearing is more labor-saving and convenient

Further, the shape of the cusp tooth is an isosceles triangle. The sawtooth is stressed more uniformly, and the edge of the paper to be torn is more neat.

Furthermore, the bottom corners of the plurality of sharp teeth are connected, so that the stress of the shell close to the edge of the paper outlet is more uniform when the paper is torn, and the paper is not easy to damage after long-term use.

Furthermore, in the bar code printer with the simple paper tearing structure, the saw teeth are uniformly distributed, paper is conveniently torn, and the edge of the paper after paper tearing is ensured to be more tidy.

In the bar code printer that has simple and easy paper structure that tears, go out the paper passageway with sawtooth horizontal distance sets up to 1.5 mm. Through the repetition test, when play paper passageway and sawtooth horizontal distance be 1.5mm, the relative position of paper and sawtooth makes the paper of tearing comparatively laborsaving, swift, convenient this moment.

The utility model has the advantages that: compared with the prior art the utility model discloses in the middle of, set up the sawtooth through integrated into one piece on printer housing, realize tearing the paper function, need not increase on purpose and tear the paper structure like metal blade etc. reduce economic cost, simple structure easily batch production, wide application.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

the utility model provides a bar printer with simply tear paper structure, includes printer main part 1, top cap 2, casing 3, and the casing parcel printer main part 1 that top cap 2 and casing 3 constitute, and top cap 2, the corresponding edge part of casing 3 enclose to close and form exit slot 4, and printer main part 1 includes paper feed rubber roll 5 and core 6, and paper feed rubber roll 5 and the 6 laminating of core form exit slot 7, and one side that casing 3 is close to exit slot 4 sets up integrated into one piece and has sawtooth 8. The sawtooth 8 is arranged on the printer shell, so that a paper tearing function is realized, paper tearing structures such as metal blades are not required to be specially added, the economic cost is reduced, the structure is simple, the mass production is easy, and the wide application is realized.

A plurality of sharp teeth (not shown) are arranged on one side of the casing close to the paper outlet, and the sharp teeth are combined to form the saw teeth. The paper tearing is more labor-saving and convenient

The shape of the sharp tooth is isosceles triangle. The sawtooth is stressed more uniformly, and the edge of the paper to be torn is more neat.

The bottom corners of the sharp teeth are connected, so that the stress of the shell close to the edge of the paper outlet is more uniform when the paper is torn, and the paper is not easy to damage after long-term use.

In the bar code printer that has simple and easy paper structure that tears, 8 evenly distributed of sawtooth conveniently tear paper, ensure to tear the edge of paper more neat after the paper.
