Detailed Description

Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the utility model, and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 5, the present utility model provides a printing paper limit structure, comprising: the paper bin 100 and the two clamping blocks 200 are used for arranging the printing paper a, and when the printing paper a is driven by other traction structures of the label printer and moves towards the printing end of the label printer, the printing paper a is limited by the two clamping blocks 200 so as to ensure that the position of the printing paper a cannot deviate.

Wherein the paper deck 100 has two parallel-arranged shutters 110 with a roller shaft 111 between the shutters 110, the roller shaft 111 being for winding and mounting the printing paper a.

The two clamping blocks 200 are respectively and elastically connected with one ends of the two baffles 110 far away from the roller shaft 111, and the opposite sides of the two clamping blocks 200 are respectively provided with a limiting groove 211, and a paper feeding channel b for passing printing paper a is formed between the two limiting grooves 211.

In particular, the printing paper a may be wound on the roller 111, and then the two clamping blocks 200 are separated from each other, so that the printing paper a can be placed between the two limiting grooves 211, and finally the two clamping blocks 200 approach each other under the action of the elastic restoring force and are attached to two sides of the printing paper a.

Further, it should be noted that the printing paper a described herein is wound around the roller shaft 111 to form a roll, and if the roller shaft 111 is rotatably connected to the flapper 110, the roll follows the roller shaft 111 to rotate relative to the flapper 110 when the printing paper a passes through the paper feeding path b, and if the roller shaft 111 is fixedly connected to the flapper 110, the roll rotates relative to the roller shaft 111 when the printing paper a passes through the paper feeding path b.

It should also be appreciated that the two baffles 110 may be integrally formed with the paper bin 100 and may also be movable relative to the paper bin 100, for example, in one embodiment, an end of the paper bin 100 near the roller 111 is provided with a receiving slot 120 for receiving the printing paper a, a guiding slot 121 for sliding the two baffles 110 relative to each other is provided in the receiving slot 120, each baffle 110 is fixedly connected with a handrail 112, and the distance between the two baffles 110 can be adjusted by the handrail 112 to accommodate the limitation of the printing paper a with different widths. For another example, in another embodiment, as will be described below, the driving mechanism 130 is mounted on the bottom of the paper bin 100 and is in driving connection with the two baffles 110 to drive the two baffles 110 to slide in opposite directions or in opposite directions.

Specifically, the driving mechanism 130 includes a motor, a gear, and two racks 131; the output shaft of the motor is coaxially fixed with the gear, the gear is respectively meshed with the two racks 131, the two racks 131 are respectively fixedly connected with the two baffles 110, and by the arrangement mode, the process of sliding the two baffles 110 in opposite directions or sliding in opposite directions is more stable by means of the meshing transmission characteristics of the gear and the racks 131.

On the basis of the foregoing embodiment, the structure of the clamping block 200 is modified for the purpose of facilitating the removal and replacement of the clamping block 200 to make it more fit the printing paper a, as will be exemplarily described below with reference to the accompanying drawings.

Referring to fig. 5, each of the clamping blocks 200 includes a clamping body 210, a connecting rod 220, an elastic member 230, and a blocking head 240; the opposite sides of the two clamp bodies 210 are respectively provided with a limiting groove 211, the opposite sides of the two clamp bodies 210 are respectively fixedly connected with a connecting rod 220, one end of the connecting rod 220, which is far away from the clamp bodies 210, is sleeved with an elastic piece 230 and penetrates through the baffle 110 to be in threaded connection with a blocking head 240, and the blocking head 240 can be abutted with the baffle 110.

In this embodiment, the plugging head 240 is detached from the connecting rod 220, and the appropriate clip body 210 is replaced, so that the clip body 210 is more attached to the printing paper a, wherein the elastic member 230 only has the function of elastically connecting the clip body 210 with the baffle 110, so that the structure, the size, the shape, etc. of the elastic member 230 are not particularly required, and all structures with elastic restoring function commonly used in the art can be used as the elastic member 230, wherein the elastic member 230 is preferably a spring, and the plugging head 240 is preferably a nut.

Further, an inclined surface is formed on a side surface of the two clamping bodies 210 opposite to each other, and the inclined surface is inclined toward the baffle 110, so that the two clamping blocks 200 are convenient to separate from each other for placing the printing paper a when the clamping bodies 210 are pressed down along the inclined surface.

In addition, a photoelectric sensor can be installed below the paper feeding channel b, and the printing paper a is generally composed of base paper and a plurality of pieces of facial tissues, the pieces of facial tissues are arranged on the base paper at intervals, and the photoelectric sensor is used for positioning gaps among the pieces of facial tissues and printing the pieces of facial tissues in cooperation with a printer. If the position of the printing paper a is deviated and vibrates up and down in the above process, the photoelectric sensor cannot be used at this time, and the paper feeding channel b has the effect of stabilizing the position of the printing paper a substantially so that the subsequent printing work can be continuously performed.

What is not described in detail in this specification is all that is known to those skilled in the art.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
