Description

Technical Field

[0001] The utility model relates to the technical field of embedded printers, in particular to an anti-pull and anti-blocking embedded printer. Background Art

[0002] Embedded printers are widely used in smart express lockers and logistics. Embedded printers generally include a main bracket, a head bracket and a paper roll bracket. The head bracket and the paper roll bracket are both connected to the main bracket. The paper roll is placed on the paper roll bracket, and the printer head is installed on the head bracket. Generally, the main bracket is installed on a frame with a horizontal surface, such as a desktop, through support plates on both sides. Therefore, the paper outlet of the printer head is parallel to the horizontal surface, which can meet the printing needs. However, during operation, the existing embedded printers will cause the printing paper to offset after it hits the desktop, which will cause paper jams. At this time, the operator needs to redeploy the printing paper in the printer, and similar situations will occur during subsequent use. If this continues, it will cause damage to the printing components of the printer. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] During operation, the existing embedded printer will cause the paper to shift after hitting the table, which will lead to paper jams. At this time, the operator needs to re-arrange the paper in the printer, and similar problems will occur during subsequent use. In the long run, it will cause damage to the printing parts of the printer. Figure 1-Figure 3The embodiment provides an embedded printer capable of preventing paper dragging and paper jamming, and solves the technical problem of paper jamming of the printer. The device comprises a printer support 1, a rear seat 2 arranged on one side of the printer support 1, and the printer support 1 and the rear seat 2 serve as a supporting base. The rear seat 2 is fixedly connected with a paper jam box 3 for fixing a paper cylinder at the top end of the rear seat 2. The printer support 1 is rotatably connected with a printer body 4 for printing paper at the top end of the printer support 1. The printer body 4 is provided with a paper ejection correcting component 5 for correcting the printed paper at the paper ejection end of the printer body 4. The printer support 1 and the rear seat 2 provide support for the printer body 4 and the paper jam box 3 respectively. The paper jam box 3 is used for limiting and storing the printed paper cylinder. The paper ejection correcting component 5 is used for correcting the paper ejected from the paper ejection end of the printer body 4.

[0030] During the printing operation of the printer body 4, the printed paper may be slightly offset at the ejection end of the printer body 4 due to the resistance of the desktop or other resistance objects, and the paper jamming may occur as the offset gradually increases. The paper ejection correcting component 5 is used to solve the problem. The paper ejection correcting component 5 comprises a correcting box 51 fixedly connected to the end of the printer support 1 away from the rear seat 2. The correcting box 51 is provided with two symmetrical clamping sliding grooves 52 at the top end. A rotating frame 53 is rotatably connected to the inner side of the correcting box 51. A pull rod 54 is rotatably connected to the top end of the rotating frame 53. A guide limiting frame 55 is slidably connected to the inner side of the clamping sliding groove 52. The bottom end of the guide limiting frame 55 is rotatably connected to the top end of the pull rod 54 away from the rotating frame 53. A rotating handle 56 is rotatably connected to the bottom end of the correcting box 51. The top end of the rotating handle 56 is connected to the bottom end of the rotating frame 53. A limiting bolt 57 is screwedly connected to the side of the rotating frame 53. The top end of the limiting bolt 57 is in contact with the surface of the bottom end of the correcting box 51. Two supporting rollers 6 are rotatably connected to the top end of the printer support 1. A buckle 7 is rotatably connected to the side of the printer support 1 and is used for limiting the printer body 4.

[0031] The printed paper cylinder is fixed by the paper jam box 3, and then the paper is printed by the printer body 4. The paper is limited by the paper ejection correcting component 5 during the printing. First, the limiting bolt 57 is loosened, and then the rotating handle 56 is rotated. The rotating handle 56 drives the rotating frame 53 connected thereto to rotate, and the rotating frame 53 drives the two pull rods 54 connected thereto to move, and drives the two guide limiting frames 55 connected to the pull rods 54 to move. The movement distance of the two guide limiting frames 55 is the same, and the two guide limiting frames 55 limit the paper. When the ejected printed paper is resisted, the guide limiting frame 55 can limit the paper to prevent the paper from being offset.

[0032] Embodiment 2

[0033] On the basis of embodiment 1, embodiment 1 solves the technical problem that the printer is easy to jam, but there is still a problem that the paper feeding end of the printing paper is easy to jam, in combination with Figure 4-Figure 5 As shown in the specific implementation process, during the operation of the printer body 4, the printing paper cylinder will rotate due to continuous paper output, and will deviate in the horizontal direction during rotation, so that the printing paper is jammed at the paper feeding end of the printer body 4. The paper shaft clamping groove 8 is provided on both sides of the jam box 3, and the support shaft 9 is slidably connected to the inner side of the two paper shaft clamping grooves 8. The paper roll limiting part 10 for clamping and limiting the printing paper cylinder is arranged between the two support shafts 9, and the paper roll limiting part 10 comprises a paper cylinder support shaft 101 rotatably connected between the two support shafts 9, and a paper cylinder limiting sleeve 102 is spirally connected to the outer side of both ends of the paper cylinder support shaft 101. The inner sides of both ends of the two paper shaft clamping grooves 8 are fixedly connected with the arc-shaped limiting elastic sheet 11, and the maximum outer diameter of the two paper cylinder limiting sleeves 102 is greater than the maximum outer diameter of the paper cylinder support shaft 101.

[0034] First, the operator will wrap the printing paper cylinder around the outer side of the paper cylinder support shaft 101, and then limit the paper cylinder in the horizontal direction through the paper cylinder limiting sleeve 102 on both sides of the paper cylinder support shaft 101. Then, the support shaft 9 rotatably connected with both ends of the paper cylinder support shaft 101 is slidably connected inside the paper shaft clamping groove 8 provided at both ends of the jam box 3, and the limiting elastic sheet 11 fixedly connected to the inner side of the paper shaft clamping groove 8 can prevent the support shaft 9 from moving vertically. By limiting the printing paper cylinder in the vertical and horizontal directions, the situation that the printing paper cylinder is jammed at the paper feeding end of the printer body 4 can be avoided.
