Paper storage structure

Technical Field

The utility model relates to a thermal printing technical field, concretely relates to paper storing structure.

Background

The thermal printer is a device which can print required patterns after being heated by a printing head and contacting with thermal printing paper, and is widely applied to various social fields due to the characteristics of convenience, high printing speed, low noise and the like. Currently, wide thermal printers used in society have a paper feeder, a cutter, a printhead assembly, and the like. Printing paper is usually assembled by using a winding drum, the position of the printing paper roll is usually arranged below a printer, the paper is conveyed to the position above the printer through a conveying component for horizontal printing, the paper is stretched to have tension in the printing process, and the printing and the paper cutting are carried out simultaneously and are continuous operation, so that the paper can be torn off due to the action of the tension when the paper is cut, the printing is interrupted, and the paper needs to be fed again when the paper is continuously printed; or printing is suspended during cutting to prevent paper from being torn off, and the two modes can cause the printing efficiency of the printer to be low.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model lies in overcoming the thermal printer among the prior art paper easy being torn open when cutting out paper, leads to printing the lower defect of efficiency to a higher paper stock structure of printing efficiency is printed in succession to the provision one kind.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Fig. 1-5 show a specific embodiment of the paper storage structure provided by the present invention, which includes: the device comprises a shell 1 with an accommodating space formed inside, a rotating shaft 3 arranged in the accommodating space and a plurality of movable pieces 4 with one ends pivoted on the rotating shaft 3.

The accommodating space has a paper inlet and a paper outlet, which are arranged substantially opposite to each other, in this embodiment, the paper inlet is arranged at the bottom and the paper outlet is arranged at the top. The rotating shaft 3 is fixed on a pair of end plates opposite to the shell along the length direction of the shell 1, and the rotating shaft 3 is close to the paper outlet. The other end that moving part 4 and pin joint end are relative is the free end, just moving part 4 with the paper import with the casing wall between the paper export forms the passageway of form advancing, moving part 4 has the laminating when initial printing and is in the paper import with follow under the impetus of paper when needs cut paper in the first position on the casing wall between the paper export the pivot 3 rotates to keeping away from the paper import with casing wall between the paper export to form the second position of the temporary storage space of paper, just the volume in temporary storage space is greater than the volume of passageway of form advancing.

Specifically, the moving part 4 towards the one side of passageway of form advancing is the cambered surface, the shape of cambered surface with correspond the shape adaptation of shells inner wall guarantees that the passageway of form advancing is more smooth and easy. The moving part 4 is a plurality of along the axial interval arrangement of pivot 3, can alleviate the total weight of moving part 4 like this for the paper can promote moving part 4 to the position of keeping away from the passageway of form advancing smoothly, and can not be because the great extrusion of paper formation of weight, guarantee the stability in space of keeping in.

Because the movable element 4 may rotate to the position right above the rotating shaft 3 under the pushing of the paper, the state that the movable element 4 cannot smoothly return to the initial position occurs, a limiting portion 2 is formed at a position on the inner wall of the housing 1 far away from the paper feeding channel, specifically, the limiting portion 2 is a protrusion arranged on the motion track of the movable element 4, namely, the protrusion is formed by extending the inner wall of the housing 1 downwards. The limiting part 2 is used for limiting the highest point reached by the free end of the moving part 4 in the rotating process, and the volume of the temporary storage space reaches the maximum at the moment.

In order to ensure that the paper can be smoothly output from the paper outlet, a guide baffle plate 5 is further arranged at a position, close to the paper outlet, of the paper feeding channel, the guide baffle plate 5 is L-shaped, the guide baffle plate 5 is fixed in the accommodating space, one part of the guide baffle plate is positioned below the rotating shaft 3 and above the paper feeding channel, and the other part of the guide baffle plate extends to a position flush with the paper outlet of the shell 1.

As shown in fig. 2, in order to smoothly convey the paper, a plurality of rollers 9 are provided on the inner wall of the housing near the paper exit. Specifically, a plurality of rollers 9 form a roller group to be installed in a through hole formed in a mounting plate 7, the mounting plate 7 is attached to the lower position of the inner wall of the shell between the paper inlet and the paper outlet, and the rollers 9 drive paper to feed paper to the paper feeding channel in the printing process, so that the speed stability of paper feeding is ensured.

The middle part of the accommodating space of the shell 1 is also provided with a counting wheel 8, the counting wheel 8 is driven to rotate when paper passes through the paper feeding channel, and the metering unit detects the number of rotation turns of the counting wheel 8 immediately. After the number of rotation turns of the counting wheel 8 is known, the consumed paper length can be calculated by combining the circumference of the counting wheel 8, so that the residual amount of the paper is estimated, and the waste of the paper is avoided.

Near the accommodation space middle position of casing 1 is equipped with sensor 6, and sensor 6 is used for detecting whether the paper normally transports at the paper feed passage, guarantees to print and normally goes on.

When printing and paper cutting are required to be carried out simultaneously, paper is input into the paper feeding channel from the paper inlet of the shell 1, and the paper is output from the paper outlet at the upper end of the shell 1 under the action of the roller 9. The speed of form advancing is slightly greater than printing speed in the in-process control of form advancing for the paper forms certain accumulation in accommodation space, thereby exerts a thrust of keeping away from the passageway of form advancing to moving part 4, forms the space of keeping in of paper, and the paper volume of depositing in casing 1 is greater than the paper volume of waiting to print and tailor like this all the time, and when cutting out paper, the tensile force that the paper received is less, has effectively avoided the tear phenomenon when cutting out paper.

As an alternative embodiment, the movable element 4 may also be one that is pivoted to the pivot axis 3.

A certain amount of paper can be pre-stored in the accommodating space of the shell 1 before printing is started, and then printing is started, so that even if the paper feeding speed and the printing speed are the same, the quantitative paper is always stored in the shell, and the interruption phenomenon in paper cutting can be avoided.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
