Abstract

The utility model relates to a thermosensitive printer which comprises a paper roll component, a printing component and a paper cutting component. The exit slot of the paper cutting component is connected with a paper containing component which comprises a box body. A paper containing motor and a transmission mechanism which is driven by the motor are fixed inside the box body. The transmission mechanism is in friction transmission with the paper containing rubber roller. The front part of the paper containing rubber roller, which is butted with the exit slot of the paper cutting component, is an upper paper containing path. The rear part of the paper containing rubber roller is the paper containing exit slot. A paper containing sensor is arranged between the upper paper containing path and the paper containing exit slot. Thus, the function of paper containing recovery is realized, the structure is simplified, and the using performance is more stable and reliable.

Description

Printer

Technical field

The utility model relates to a kind of public automation equipment, particularly a kind of thermosensitive type printer.

Background technology

Along with the development of economic technology, social public utilities have obtained tremendous development, and particularly along with fast development of information technology, the popularization and application of the public automation equipment of various " self-service " formulas has greatly promoted social utility development.The public automation equipment of " self-service " formula mainly is made up of main frame, print out equipment, network and application software, housing parts.Be applied to the printer needs of this kind equipment: print speed is fast, print quality height, reliability, stability height.Own characteristic and advantage because of the hot print technology, the basic thermal printer of using entirely of the printout part of the public automation equipment of " self-service " formula, consider the characteristics of " self-service " equipment, on the basis of traditional thermal printer, increased the appearance mechanism of paper, its effect has two: one, before whole page or leaf is opened the file printout end, file holds at device interior, avoids " client " to cause equipment fault because of doing one's utmost to tear paper; The 2nd, if " client " just needs or forget and take institute's typescripts away, equipment can retreat to this document in the appearance paper device of device interior automatically, is scattered to the influence of environment to avoid paper.

The mechanism of existing appearance paper adopts the turnover plate type structure mostly, needs the control of a plurality of motors and a plurality of sensor.Structure composition and control thereof are complicated, component parts requirement on machining accuracy height, and the cost height holds mechanism of paper and the integrative-structure that whole print unit mixes, and makes maintenance, operation, uses complexity.

Summary of the invention

The utility model purpose is exactly at the deficiencies in the prior art, and a kind of technical scheme with the thermal printing unit that can hold the paper recovery is provided,

The utility model is achieved in that it comprises paper roll assembly, print components and cut paper assembly, holds the paper assembly in one of the exit slot connection of cut paper assembly.

Hold the paper assembly and comprise a casing, the transmission mechanism that holds paper motor and driving thereof is set in the casing, this transmission mechanism and appearance paper rubber roll frictional drive, the front portion that holds the paper rubber roll is the appearance paper upper channel that docks with cut paper assembly exit slot, the rear portion that holds the paper rubber roll is to hold the paper exit slot, on the path that holds between paper upper channel and the appearance paper exit slot appearance paper sensor is set.An appearance letterweight plate of casing upset relatively is set above appearance paper upper channel.Casing comprises two parts up and down, and its top is for holding the fixed head of paper rubber roll, the lower box upset relatively of this fixed head.Hold the letterweight plate and be fixed on the fixed head that holds the paper rubber roll, and hinged with fixed head.Be provided with below the appearance paper upper channel in casing and hold the paper lower channel.Adopt the utility model, hold the paper passage and be divided into upper and lower appearance paper passage, by a motor and a sensor control paper feed, realize holding paper and reclaim function, simplify the structure, serviceability is more reliable and more stable, the maintaining in easy to use.Have the paper rubber roll that go up to hold of this programme to be fixed on and to hold on the paper fixed head again, fixed head can be dug, and is convenient to fill in the maintenance behind the paper.

The specific embodiment

Referring to accompanying drawing 1,2,3,4, it comprises paper roll assembly A, print components B and cut paper assembly C, holds paper assembly D in one of the exit slot connection of cut paper assembly C.Hold the paper assembly and comprise a casing, the transmission mechanism 15 that holds paper motor 3 and drive is set in the casing, this transmission mechanism 15 and appearance paper rubber roll 1 frictional drive, the front portion that holds paper rubber roll 1 is the appearance paper upper channel 14 that docks with cut paper assembly exit slot, the rear portion that holds paper rubber roll 1 is to hold paper exit slot 17, is provided with on the path that holds between paper upper channel 14 and the appearance paper exit slot 17 and holds paper sensor 2.Above appearance paper upper channel 14, be provided with one and hold letterweight plate 18.Casing comprises two parts up and down, and its top is for holding the fixed head 19 of paper rubber roll, and this fixed head 19 lower box relatively overturns, and this fixed head that overturns can solve plug paper problem.Hold letterweight plate 18 and be fixed on the fixed head 19 that holds the paper rubber roll, and hinged with fixed head 19.Be provided with below the appearance paper upper channel 14 in casing and hold paper lower channel 4.

The utility model in use, paper roll is placed on the paper roll holder 7, the paper roll head is placed in to be printed between rubber roll 11 and the printhead 10, after paper exists sensor 9 to detect paper, after printing motor 5 driving printing rubber rolls 11 make paper pass through between printhead 10 and the printing rubber roll 11, be in wait to print SBR this for automatically going up the paper mode, the semi-automatic paper mode that goes up is: lift printhead 10, paper is passed between printhead 10 and the printing rubber roll 11, and by last paper sensor 12, after last paper sensing 12 is surveyed, print motor 9 and drive 11 revolutions of printing rubber roll, make paper be in SBR to be printed;

Referring to Fig. 3, send print command after, print motor 10 and drive and print rubber rolls 11 and rotate, begin to print and paper advance; Hold paper motor 3 simultaneously and drive 1 rotation of appearance paper rubber roll, paper 20 stops in exit slot 17 through after holding paper rubber rolls 1 and appearance paper sensor 2; Print rubber roll 11 this moment and continue to print and paper is moved ahead, arch upward and hold letterweight plate 18;

Referring to Fig. 4, after printing finished, cutting knife 13 downcut tickets and opens 20, printed motor 10 and drove 11 revolutions of printing rubber roll, paper is in treats print state; Hold paper motor 3 simultaneously and drive 1 rotation of appearance paper rubber roll, ticket Zhang Jixu is moved ahead, hold letterweight plate 18 and depress gradually this moment, ticket is opened through holding paper sensor 2 and is spued from exit slot 17, until hold paper rubber roll 1 only clamp ticket open afterbody a little, most of ticket is opened and is exposed at exit slot 17 outsides

Referring to Fig. 5, the user opens content according to ticket, can take ticket when needing away and open, and hangs on when not required, and paper sensor 2 is surveyed and 3 controls of appearance paper motor by holding, and drives and holds 1 revolution of paper rubber roll, makes ticket open 20 and refunds, and is recovered in down in the appearance paper passage 4.So far, the printing interval end that ticket is opened can be carried out the printing that next ticket is opened.
