The related literature can refer to Chinese patent utility model 'thermal printer with cover detection' with patent number ZL202020317450.4 (grant bulletin number CN 212098013U); reference may also be made to the chinese utility model patent No. ZL 202022173742.8, "a thermal printer for large rolls of paper" (grant bulletin No. CN 213734167U).

At present, the width dimension of printing paper in a common paper roll box is basically fixed, so that a printer can only be suitable for one printing paper and cannot achieve multiple purposes.

Disclosure of Invention

The first technical problem to be solved by the present utility model is to provide a paper roll box which can be suitable for printing roll paper with various widths.

The second technical problem to be solved by the present utility model is to provide a thermal printer core suitable for printing roll paper with various widths.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: the utility model provides a stock form box, includes the box body and locates the apron that can open on the box body, its characterized in that box body bottom both sides are formed with a plurality of constant head tanks in perpendicular play paper direction, and correspondingly, every side is equipped with respectively with the side shield that can restrict the lateral shifting of scroll, and the lower terminal surface of every side shield has the spacer bar with the aforesaid constant head tank adaptation, and the interval between two side shields matches with the width of printing paper. The detachable structure of the roll paper box and the host machine is preferably designed as follows: the rear end of the stand is provided with a connecting hole, and correspondingly, the front end of the roll paper box is extended with a hook part which can be detachably inserted into the connecting hole.

A plurality of positioning grooves are formed in the two sides of the inner bottom of the paper roll box in the direction perpendicular to the paper outlet direction, correspondingly, each side is correspondingly provided with a side baffle plate which can limit the paper roll to be transverse, the lower end face of each side baffle plate is provided with a positioning rib which is matched with the positioning groove, and the distance between the two side baffle plates is matched with the width of printing paper. The side baffle is adapted with the constant head tank through the spacer bar of bottom to adjust the lateral width of stock form, so that the stock form can not swing back and forth by a wide margin at the paper feed in-process, influence printing quality.

The middle part of the bottom of the paper outlet end of the paper roll box is provided with a protruding stop block for limiting paper rolls to be pulled out of the paper roll box, the inner side surface of the stop block is an arc surface, and the positioning grooves are arranged on two sides of the stop block.

When the roll paper is pulled before printing, the stop block can play a role of limiting and blocking, so that the roll paper is prevented from being directly pulled out of the roll paper box, and the problem of scratch of printing paper caused by friction with the outer wall of the host machine is also prevented.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: the utility model provides a thermal printer core, including the host computer and locate the stock form box of host computer rear end, foretell host computer has paper inlet and paper outlet, foretell host computer includes the flip on locating the frame that frame and can overturn, the up end of foretell frame can be pivoted is equipped with the rubber roll, foretell flip medial surface is equipped with the thermal print head, foretell rubber roll and thermal print head draw close under the state of foretell frame of aforesaid flip closure, the printing paper then passes through from the clearance between rubber roll and the thermal print head, the paper outlet of foretell stock form box corresponds the paper inlet setting of host computer.

Compared with the prior art, the utility model has the advantages that: through the matching of the locating rib and the locating grooves at different positions, the purpose of adjusting the transverse width of the roll paper is achieved, the output roll paper is ensured to be stable, the roll paper does not swing randomly, and the printing quality is improved.
