Abstract
The utility model discloses a printer blade structure. The printer blade structure comprises a blade having a cutting edge. The surface of the blade is plated with a metal layer to improve hardness of the blade. The metal layer which is plated on the surface of the blade is a hard chrome layer or a titanium alloy layer which enables the hardness of the surface of the blade to reach HV800 to 1000. According to the printer blade structure provided by the utility model, through increasing the hardness of the blade surface, abrasion loss of the cutting edge is decreased, or the cutting edge is free of abrasion, and as a result, a design and use requirement that the blade can be used for 1 million times or more than 1 million times can be satisfied.
Description
Technical field
The utility model discloses a kind of printer blade structure, divides by International Patent Classification (IPC) (IPC) to belong to printer member technical field, especially is applied to the cut paper blade configuration of thermal printer.
Background technology
Advantages such as thermal printer is fast owing to speed, printing is clear are used more and more widely, when thermal printer is exported at the terminal, need cut paper equipment that coil paper is cut off.The cut paper blade case hardness of cut paper equipment is lower in the existing printer, causes blade position easy abrasion, and the blade manufacture craft is: blade shaping--heat-treatment quenching--sharpening mouth, the case hardness of blade is: HRC51～60.According to statistics, in only about 300,000 times of the service life of existing printer cut paper blade, do not reach 1,000,000 times design and use requirement.
Summary of the invention
To the deficiency of prior art, the utility model provides the printer blade structure of the big and long service life of a kind of hardness.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of printer blade structure comprises blade, and it has blade, and described blade face is coated with metal level to improve blade hardness.
Further, described metal level is to make blade face hardness reach HV800～1000 at blade face hard chrome plating or titanizing alloy-layer.
The utility model makes the wear extent at blade position reduce or be close to not wear and tear through improving blade face hardness, through statistics, meets and exceeds 1,000,000 times design and use requirement the service life of the utility model blade.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1, a kind of printer blade structure comprises blade 1, and it has blade 11, and described blade 1 surface is coated with metal level to improve blade hardness.Described metal level is to make blade face hardness reach HV800～1000 at blade face hard chrome plating or titanizing alloy-layer.
The concrete scheme of the utility model is following:
Adopt martensitic stainless steel drawing blade blank part; Make piece surface hardness reach HRC50～60 through heat treatment; The carbide tips cutting edge; Guarantee that knife edge position is sharp and do not have the grinding burr; Plating hard chromium on surface or titanizing alloy make piece surface hardness reach HV800～1000 (being equivalent to HRC63～69), and all can reach more than 1,200,000 times the service life through actual test blades.
The hand papercutter processing step of thermal printer: blade shaping--heat-treatment quenching--sharpening mouth--plating hard chromium on surface or titanizing alloy; The case hardness of blade is: HV800～1000 (being equivalent to HRC63～69), blade sharpening mouth carries out plating hard chromium on surface or titanizing alloy later on.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
Claims (2)
