Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a guide structure for preventing paper jams in a paper bin of a portable printer and a printer. Background Art

[0002] At present, portable printers are increasingly used in commercial and home scenarios as small item management label printing machines. The use of these machines requires the use of corresponding consumables (label paper) to complete label printing. During use, paper jams often occur, which brings inconvenience to the user experience.

[0003] Existing label printing machines include a paper bin for accommodating a label roll, which includes an outlet for outputting label paper from the label roll. During printing, the free end of the label paper on the outermost ring of the label roll is pre-placed at the outlet. A rubber roller is provided at the outlet, and then a power assembly drives the rubber roller to rotate and pull the label paper for continuous output. After a certain period of use, the label paper is consumed, causing the diameter of the label roll to decrease. At this time, the label paper at the outlet will fall back into the paper bin when not in use, and then curl or even get stuck inside the paper bin, causing paper jams and affecting the user experience of the product.

[0004] In other words, the structural design of existing label printers can cause the label paper roll to fall back after prolonged use, curling or even clogging the paper hopper, leading to paper jams. Therefore, preventing label paper jams through product design and improving the user experience is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0005] In response to the problems in the prior art, the present application proposes a guide structure and a printer based on a portable printer to prevent paper jams in the paper bin.

[0006] In order to achieve the above technical objectives, as a first aspect, the present invention proposes a guide structure for preventing paper jams in a portable printer paper bin, and the guide structure for preventing paper jams in a portable printer paper bin includes:

[0007] A paper bin, the top of which is open and the interior of which is used to accommodate a label paper roll, and the paper bin includes a paper outlet, the paper outlet being used to guide the label paper of the label paper roll out;

[0008] A rubber roller cover body, the rubber roller cover body being buckled at the top opening of the paper bin, a paper stop structure being provided on the side of the rubber roller cover body facing the paper bin, the paper stop structure being located on the paper return path of the label paper in the paper bin;

[0009] Preferably, the paper blocking structure is provided at an end of the rubber roller cover body facing the paper bin away from the paper outlet;

[0010] Preferably, the inner contour of the paper bin is a first arc shape with a radius R1;

[0011] The paper blocking structure includes a guide block, and the guide block includes a guide surface of a second arc with a radius of R2;

[0012] Wherein, the R1 is equal to the R2;

[0013] Preferably, at least one pair of limiting components is further provided inside the paper bin on the paper discharge path, wherein the pair of limiting components are symmetrically distributed on opposite sides of the paper discharge path, and the distance between the pair of limiting components is adapted to the width of the label paper;

[0014] Preferably, the limiting assembly includes a limiting rib, and the limiting rib is arranged at an end of the paper away from the guide block;

[0015] Preferably, the limiting rib is vertically arranged from the top opening of the paper bin to the inner bottom of the paper bin;

[0016] Preferably, the number of the limiting ribs is multiple pairs, and the limiting ribs adjacent to each other on the same side are arranged at intervals.

[0017] As a second aspect, the present invention proposes a printer, which includes any one of the above-mentioned guide structures for preventing paper jams in a portable printer paper bin.

[0018] The beneficial effect of this utility model is reflected in the fact that by providing a paper stop structure on the side of the rubber roller cover facing the paper bin, after label printing stops, the paper backing down the paper return path is supported by the paper stop structure against the side of the label paper falling back due to gravity, thereby preventing the label paper from continuously sliding into the paper bin, causing longer lengths of label paper to curl or even become clogged and cause paper jams. This solves the problem of paper jams caused by existing portable printers that do not have an internal paper stop structure, and greatly improves the user experience of the product.

[0028] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0029] like Figure 1-4 As shown, as a first aspect, the utility model proposes a guide structure based on a portable printer to prevent paper jams in the paper bin 1. The guide structure based on the portable printer to prevent paper jams in the paper bin 1 includes: a paper bin 1 and a rubber roller cover 2,

[0030] Among them, the top opening 101 of the paper bin 1 is used to accommodate the label paper roll 3 inside. The paper bin 1 includes a paper outlet, which is used to guide the label paper 301 of the label paper roll 3 to be discharged; the rubber roller cover 2 is buckled at the top opening 101 of the paper bin 1, and a paper blocking structure 201 is provided on the side of the rubber roller cover 2 facing the paper bin 1. The paper blocking structure 201 is located on the paper return path of the label paper 301 in the paper bin 1.

[0031] Specifically, by providing a paper stop 201 on the side of the rubber roller cover 2 facing the paper bin 1, after label printing stops, the paper stop 201 supports the side of the label paper 301 as it falls back along the paper return path. This prevents the label paper 301 from continuously sliding into the paper bin 1, causing further curling or even clogging, leading to paper jams. This solves the paper jam problem caused by existing portable printers that lack an internal paper stop 201, significantly improving the user experience.

[0032] Furthermore, the paper stop structure 201 is arranged at the end of the rubber roller cover 2 facing the paper bin 1 away from the paper outlet. When printing stops, the free end of the label paper 301 falls back to the paper bin 1, causing the outermost label paper 301 of the label paper roll 3 to loosen or even fall off the paper roll. In this embodiment, the paper stop structure 201 is arranged at the end of the rubber roller cover 2 facing the paper bin 1 away from the paper outlet to support the segment of the label paper 301 away from the paper outlet. Since the label paper 301 has a certain hardness, the label paper 301 located in the length section on one side of the paper outlet is stably supported and will not completely slide into the paper bin 1 to cause curling or clogging.

[0033] Furthermore, the internal contour of the paper bin 1 is a first arc shape with a radius of R1. The paper retaining structure 201 includes a guide block, which includes a second arc guide surface with a radius of R2. R1 and R2 are equal. This allows the guide block, facing the paper bin 1, to form an arc guide surface that matches the internal contour of the paper bin 1, adapting to the shape of the label paper roll 3. Furthermore, the arc guide surface can better guide and adhere the label paper 301.

[0034] Further, see Figure 2 A groove is provided in the middle of the arc-shaped guide surface of the guide block to facilitate the connection between the cover body and the box body in the portable printer through the connecting assembly.

[0035] Furthermore, in order to prevent the label paper 301 from shaking when it is discharged from the paper outlet, at least one pair of limiting components 4 is provided inside the paper bin 1 on the paper discharge path. The pair of limiting components 4 are symmetrically distributed on opposite sides of the paper discharge path to form a limiting space, and the spacing between the pair of limiting components 4 is adapted to the width of the label paper 301 on the label paper roll 3. In this way, when the paper is discharged, the discharge direction of the label paper 301 is guided by the limiting space, thereby preventing the disadvantage of shaking left and right when the paper is discharged.

[0036] Furthermore, the limiting assembly 4 includes limiting ribs located at the end of the paper away from the guide block. This forms a bidirectional limit for the paper 301 in both paper output and paper return, and the limiting ribs are arranged vertically from the top opening 101 of the paper bin 1 to the inner bottom of the paper bin 1.

[0037] Furthermore, in order to strengthen the limiting effect of the limiting ribs on the label paper 301 in the paper output direction, there are multiple pairs of limiting ribs, and adjacent limiting ribs on the same side are arranged at intervals.

[0038] As a second aspect, the utility model proposes a printer, which includes any one of the above-mentioned guide structures for preventing paper jams in the portable printer paper bin 1, and a paper blocking structure 201 is set on the side of the rubber roller cover 2 facing the paper bin 1 through the guide structure for preventing paper jams in the portable printer paper bin 1, so that after stopping label printing, when the label paper 301 falls back along the paper return path, the gravity-falling side of the label paper 301 is supported by the paper blocking structure 201, thereby preventing the label paper 301 from continuously sliding into the paper bin 1, causing more lengths of label paper to curl 3 or even get stuck, and then causing paper jams.
