[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. During the use of a printer, paper needs to be fed into the printer, which requires the use of a paper transport structure for auxiliary transport.

[0003] In practical applications, the existing paper transport structures are relatively complete in structure and function, and can meet basic usage requirements, but the following problems still exist:

[0004] In actual use, the paper often enters the printer at an angle due to the paper's position shift during transmission, which can easily cause paper jams. This requires manual removal of the jammed paper, which is very inconvenient.

[0005] Therefore, this utility model provides a paper transport structure for an anti-paper jam printer. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a paper transport structure for an anti-paper jam printer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a paper transport structure for an anti-paper jam printer, comprising a printer body, wherein a paper placement frame is fixedly connected to one side of the printer body; an auxiliary limiting structure is provided on the top and one side of the paper placement frame, the auxiliary limiting structure comprising a first screw, one end of the first screw being threadedly connected to one side of the paper placement frame, and a rectangular plate being rotatably connected to the outer surface of the first screw; a transmission paper guide structure is provided inside the printer body, the transmission paper guide structure comprising a paper guide groove, the paper guide groove being opened on one side of the printer body, and a drive motor being fixedly installed on one side of the printer body.

[0008] In a preferred embodiment, a sliding rod is fixedly connected to one side of the rectangular plate, the sliding rod is slidably disposed on one side of the paper frame, a first operating block is fixedly connected to one end of the first screw, and a baffle is fixedly connected to the top of the rectangular plate.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the first screw, the baffle can be driven to move, so that the paper can be limited in the front and back direction, and the paper can be aligned between the baffle and the paper guide groove, thereby facilitating paper guiding and reducing the paper jam rate.

[0010] In a preferred embodiment, a rectangular frame is fixedly connected to the top of the paper-holding frame, and a second screw is rotatably arranged between the two sides of the rectangular frame. The two ends of the second screw have opposite thread directions, and two screw hole blocks are symmetrically threaded to the outer surface of the second screw. A sliding block is fixedly connected to the top of the screw hole block, and a fixing rod is fixedly connected between the two sides of the rectangular frame. The sliding block is slidably connected to the outer surface of the fixing rod. A second operating block is fixedly connected to one end of the second screw, and a rectangular through groove is opened at the bottom of the rectangular frame. A sliding connecting rod is fixedly connected to the bottom of the screw hole block, and a clamping plate is fixedly connected to the bottom end of the sliding connecting rod.

[0011] The technical effect of adopting the above-mentioned further solution is that: under the action of the second screw, the screw hole block can be driven to move, which in turn can drive the sliding connecting rod and the clamping plate to move, which can then assist in limiting the two sides of the paper, thereby aligning the paper in all directions, fixing the angle at which the paper enters the paper guide groove, and thus reducing the paper jam rate.

[0012] In a preferred embodiment, a rotating rod is fixedly connected to the output end of the drive motor, and a paper guide roller is fixedly connected to the outer surface of the rotating rod. The lateral cross-section of the paper guide roller is triangular. An installation groove is provided at the bottom of the paper guide groove. A wheel axle is symmetrically rotatably connected between the two sides of the installation groove. A guide roller is fixedly connected to the outer surface of the wheel axle, and an annular protrusion is fixedly connected to the outer surface of the guide roller.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the paper guide roller and the paper guide groove, the paper entering the printer body can be guided, and at the same time, under the action of the guide roller, the paper can be further guided.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting an auxiliary limiting structure, the first screw can drive the baffle to move, thereby limiting the front and rear position of the paper. The second screw and screw hole block can limit the lateral position of the paper, thus fixing the angle at which the paper enters the printer body. This reduces the paper jam rate and eliminates the need for frequent paper jam cleaning, making it very convenient. By setting a transmission paper guide structure, the paper guide roller and rotating rod work together to squeeze and carry the paper forward during rotation. At the same time, the guide roller reduces the friction between the paper and the edge of the paper guide groove inside the printer body, thereby reducing the paper jam rate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5As shown, this embodiment provides a technical solution: a paper transport structure for an anti-jamming printer, including a printer body 1, a paper frame 2 fixedly connected to one side of the printer body 1; an auxiliary limiting structure 3 is provided on the top and one side of the paper frame 2, the auxiliary limiting structure 3 including a first screw 31, one end of the first screw 31 being threadedly connected to one side of the paper frame 2, and a rectangular plate 32 being rotatably connected to the outer surface of the first screw 31; a transmission paper guide structure 4 is provided inside the printer body 1, the transmission paper guide structure 4 including a paper guide groove 41, the paper guide groove 41 being opened on one side of the printer body 1, and a drive motor 42 fixedly installed on one side of the printer body 1. By setting the auxiliary limiting structure 3, under the action of the first screw 31, a paper guide structure 42 is provided. The lower part can drive the baffle 35 to move, thereby limiting the front and rear position of the paper. Under the action of the second screw 37 and the screw hole block 39, the position of the paper on both sides can be limited, thereby fixing the angle at which the paper enters the printer body 1, thus reducing the paper jam rate and eliminating the need for frequent paper jam cleaning operations, which is very convenient. By setting the transmission paper guide structure 4, under the action of the paper guide roller 44 and the rotating rod 43 and other components, the protrusion of the paper guide roller 44 can squeeze and carry the paper forward during rotation. At the same time, under the action of the guide roller 47, the friction between the paper and the edge of the paper guide groove 41 inside the printer body 1 is reduced, thereby reducing the paper jam rate.

[0027] Going further, such as Figure 2 As shown: A sliding rod 34 is fixedly connected to one side of the rectangular plate 32. The sliding rod 34 is slidably disposed on one side of the paper frame 2. A first operating block 33 is fixedly connected to one end of the first screw 31. A baffle 35 is fixedly connected to the top of the rectangular plate 32. Under the action of the first screw 31, the baffle 35 can be driven to move, so that the front and back directions of the paper can be limited, so that the paper is aligned between the baffle 35 and the paper guide groove 41, thereby facilitating paper guiding and reducing the paper jam rate.

[0028] The above solutions still have the problem of paper jams when the two sides of the paper are misaligned. Figure 3 and Figure 4As shown: In this design, a rectangular frame 36 is fixedly connected to the top of the paper frame 2. A second screw 37 is rotatably mounted between the two sides of the rectangular frame 36. The two ends of the second screw 37 have opposite thread directions. Two screw hole blocks 39 are symmetrically threaded onto the outer surface of the second screw 37. A sliding block 311 is fixedly connected to the top of the screw hole blocks 39. A fixing rod 310 is fixedly connected between the two sides of the rectangular frame 36. The sliding block 311 is slidably connected to the outer surface of the fixing rod 310. A second operating block 38 is fixedly connected to one end of the second screw 37. The bottom of the rectangular frame 36 is provided with a rectangular through groove 312. The bottom of the screw hole block 39 is fixedly connected to a sliding connecting rod 313. The bottom end of the sliding connecting rod 313 is fixedly connected to a clamping plate 314. Under the action of the second screw 37, the screw hole block 39 can be driven to move, which in turn can drive the sliding connecting rod 313 and the clamping plate 314 to move, thereby providing auxiliary limiting on both sides of the paper, so that the paper is aligned front, back, left and right, and the angle at which the paper enters the paper guide groove 41 is fixed, thereby reducing the paper jam rate.

[0029] The above solutions also have the problem of excessive friction between the paper and the bottom of the paper guide groove 41, which easily leads to paper jams. Figure 5 As shown, a rotating rod 43 is fixedly connected to the output end of the drive motor 42. A paper guide roller 44 is fixedly connected to the outer surface of the rotating rod 43. The lateral cross-section of the paper guide roller 44 is triangular. An installation groove 45 is provided at the bottom of the paper guide groove 41. A wheel axle 46 is symmetrically rotatably connected between the two sides of the installation groove 45. A guide roller 47 is fixedly connected to the outer surface of the wheel axle 46. An annular protrusion 48 is fixedly connected to the outer surface of the guide roller 47. Under the action of the paper guide roller 44 and the paper guide groove 41, the paper entering the printer body 1 can be guided. At the same time, under the action of the guide roller 47, the paper can be assisted in being guided.

[0030] Working principle:

[0031] like Figure 1-5 As shown:

[0032] In use: When in use, place the paper inside the paper frame 2, then rotate the first screw 31 so that the first screw 31 can drive the rectangular plate 32 to move, which in turn can drive the baffle 35 to move, thereby fitting and limiting the paper.

[0033] At this time, rotating the second screw 37 will cause the screw hole block 39 to move, which in turn will cause the sliding block 311 to slide on the outer surface of the fixed rod 310, which will in turn cause the sliding connecting rod 313 and the clamping plate 314 to move.

[0034] At this time, the drive motor 42 is started, which can drive the paper guide roller 44 to rotate, thereby guiding the paper into the printer body 1. During the paper entry process, the guide roller 47 and the wheel axle 46 can be driven to rotate, thereby assisting in guidance.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
