Description
Technical field
The present invention relates to printer field, it is specifically related to a kind of thermal printer and heat-sensitive sheet installation method.
Background technique
In thermal printer, heat-sensitive sheet is mounted on temperature-sensitive plate rack, in print procedure.Need to keep heat-sensitive sheet with
Relative position between rubber roller is stablized, and can just have better printing effect.Cut paper component, cut paper group are additionally provided in printer
Part includes cut paper driving assembly and cutter, and cut paper driving assembly drives cutter to move towards the paper feed channel between rubber roller and heat-sensitive sheet
It is dynamic；But mobile cutter is easy to interfere temperature-sensitive plate rack, so that the position of temperature-sensitive plate rack is built on the sand, imitates to printing
Fruit affects.Currently, needing to carry out the complete machine of printer machine if the heat-sensitive sheet on temperature-sensitive plate rack goes wrong
Disassembly, the installation steps of temperature-sensitive plate rack and demounting procedure complexity trouble, for the heat-sensitive sheet later period demolition and maintenance extremely not yet
Just.
Summary of the invention
The first object of the present invention is to provide a kind of thermal printer for reducing and interfering temperature-sensitive plate rack installation site.
The second object of the present invention is to provide a kind of heat-sensitive sheet installation side for reducing and interfering temperature-sensitive plate rack installation site
Method.
In order to realize the first above-mentioned purpose, heat-sensitive sheet printer provided by the invention includes shell, middle frame, printing group
Part, temperature-sensitive covering and cover；Center frame is arranged inside the shell, and temperature-sensitive accommodating chamber is provided on middle frame；Print components are set
It sets on middle frame, print components include temperature-sensitive plate rack, heat-sensitive sheet, rubber roller and elastic component, are set between heat-sensitive sheet and rubber roller
It is equipped with paper feed channel, temperature-sensitive plate rack is arranged in towards on the side of rubber roller in heat-sensitive sheet, is provided on the side wall of temperature-sensitive accommodating chamber
Mounting groove, mounting groove are connected to temperature-sensitive accommodating chamber, and mounting groove includes first sliding groove and support slot, and first sliding groove and support slot connect
It is logical, opening is provided in first sliding groove, opening is connected to first sliding groove, and temperature-sensitive plate rack is supported in support slot, elastic component position
In in temperature-sensitive accommodating chamber, the first end of elastic component is abutted on temperature-sensitive plate rack, and elastic component applies towards rubber roller temperature-sensitive plate rack
Press force；Temperature-sensitive covering includes lid, and ear is provided on lid, and temperature-sensitive covering is covered on outside temperature-sensitive accommodating chamber, ear
Portion is located in opening；Cover is articulated with middle frame, and rubber roller is arranged in cover direction on the side of frame.
It can be seen that one end of temperature-sensitive plate rack is during installation, passes through opening and enter in mounting groove, the installation of temperature-sensitive plate rack
In temperature-sensitive accommodating chamber, temperature-sensitive covering covers temperature-sensitive accommodating chamber, while the ear of temperature-sensitive covering is located at temperature-sensitive accommodating chamber
