Description

Technical Field

[0001] This utility model belongs to the field of thermal printing technology, and more specifically, it relates to an industrial printer with a thermal support leveling mechanism. Background Technology

[0002] With the widespread application of thermal printers, they are used not only in bank ATMs, supermarket cash registers, and e-commerce shipping points, but also in the rapidly growing e-commerce and express delivery industries, which place higher demands on the stability, durability, and printing accuracy and speed of printers.

[0003] Based on the above, the following problems were found: Existing thermal printers typically adjust the thermal support by moving an external lever, which results in insufficient adjustment accuracy. Furthermore, existing thermal printers often require placing a roll of paper inside the printer. This involves pushing the paper gripper to the sides and then placing the paper in the center of the gripper for clamping and limiting. Because the gripper is movable, prolonged use can lead to the paper easily separating from the gripper when the paper is rotated and released.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an industrial printer with a thermal bracket leveling function, in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an industrial printer with a thermal bracket leveling mechanism. This addresses the issues that, after prolonged use, the paper roll may easily separate from the clamping device during paper feeding and the bracket's adjustment accuracy may be insufficient.

[0006] This utility model provides an industrial printer with a thermal bracket leveling mechanism, achieved through the following specific technical means:

[0007] An industrial printer with a thermal bracket leveling mechanism includes a housing, a cover hinged to the top of the housing, a groove at one end of the top of the housing, a protrusion fixed to the bottom of one end of the cover, a bracket body rotatably connected inside the protrusion, a first leveling knob on one side of the cover, a second leveling knob on one side of the first leveling knob, a placement groove inside the bracket body, extrusion plates movably mounted at both ends of the bottom of the inner wall of the housing, racks fixed to the bottom of opposite sides of the two extrusion plates, a pull rod fixed to one end of one rack, a gear rotatably connected to the middle of the bottom of the inner wall of the housing, a spring fixed to the middle of the bottom of opposite sides of the two extrusion plates, and an extrusion block rotatably connected to the top of opposite sides of the two extrusion plates.

[0008] Furthermore, a groove is provided at the bottom of the inner wall of the housing, and a slider is fixed at the bottom of the extrusion plate, with the slider slidably connected to the groove.

[0009] Furthermore, the teeth of the two racks are arranged in a relatively parallel manner, and both racks mesh with gears.

[0010] Furthermore, the pull rod slides through the bottom of the housing, and a connecting block is fixed to one end of the pull rod.

[0011] Furthermore, the first grading knob is rotatably connected to the support body, and both the second grading knob and the first grading knob have marking holes on one side. The second grading knob is used to control the rotation of the first grading knob. When the second grading knob rotates one revolution, the first grading knob rotates by 1 degree.

[0012] Furthermore, the outer wall of the shell cover is provided with a scale groove, which is located on the outer shell cover of the first grade knob and is arranged in a circumferentially equidistant manner.

[0013] Furthermore, both of the extrusion blocks are frustum-shaped on opposite sides, and the extrusion blocks are rotatably connected to the extrusion plate via bearings.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, by pulling the connecting block, the pull rod moves in the middle of the machine housing, thereby driving the rack to move. One rack moves, driving the gear to rotate, which in turn drives the other rack to move in the opposite direction, separating the two extrusion plates. Then, the roll of paper is placed at the extrusion block. The frustum-shaped extrusion block can better connect with rolls of paper of different sizes. After the roll of paper is placed, the connecting block is released, and the spring pulls the two extrusion plates closer to the middle, limiting the roll of paper. This achieves better roll paper limiting and makes it more convenient to pick up and put down the roll of paper.

[0016] 2. In this utility model, rotating the first grade knob drives the second grade knob to rotate at a micro-angle, which in turn drives the support body to rotate at a micro-angle. The angle of the internal support body is determined by the marking holes corresponding to the scale grooves at different positions, thereby achieving the effect of precisely adjusting the angle of the thermal support.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an industrial printer with a thermal bracket leveling function, including a housing 1, a cover 2 hinged to the top of the housing 1, a groove 4 at one end of the top of the housing 1, a protrusion 3 fixed to the bottom of one end of the cover 2, a bracket body 18 rotatably connected inside the protrusion 3, a first grading knob 5 on one side of the cover 2, a second grading knob 6 on one side of the first grading knob 5, a placement groove 19 inside the bracket body 18, extrusion plates 10 movably installed at both ends of the bottom of the inner wall of the housing 1, racks 13 fixed to the bottom of the opposite side of the two extrusion plates 10, a pull rod 16 fixed to one end of one rack 13, a gear 12 rotatably connected to the middle of the bottom of the inner wall of the housing 1, a spring 11 fixed to the middle of the bottom of the opposite side of the two extrusion plates 10, and an extrusion block 15 rotatably connected to the top of the opposite side of the two extrusion plates 10.

[0028] The inner wall of the housing 1 has a groove 8 at the bottom, and the bottom of the extrusion plate 10 has a slider 9 fixed thereon. The slider 9 is slidably connected to the groove 8, and the extrusion plate 10 is connected to the bottom of the housing 1 through the cooperation of the groove 8 and the slider 9.

[0029] The two racks 13 have teeth that are relatively parallel to each other. Both racks 13 mesh with the gear 12. The movement of one rack 13 drives the gear 12 to rotate, which in turn drives the other rack 13 to move in the opposite direction.

[0030] The pull rod 16 slides through the bottom of the housing 1, and a connecting block 17 is fixed at one end of the pull rod 16. By pulling the external connecting block 17, the pull rod 16 can be moved in the middle of the housing 1, thereby driving the rack 13 to move.

[0031] The first grading knob 5 is rotatably connected to the support body 18. The second grading knob 6 and the first grading knob 5 are both provided with marking holes 7 on one side. The second grading knob 6 is used to control the rotation of the first grading knob 5. When the second grading knob 6 rotates one revolution, the first grading knob 5 rotates by 1 degree. By rotating the first grading knob 5, the second grading knob 6 is driven to rotate at a small angle, which in turn drives the support body 18 to rotate at a small angle.

[0032] The outer wall of the shell cover 2 is provided with a scale groove 31. The scale groove 31 is located on the outer shell cover 2 of the first grade knob 5 and is arranged in a circumferentially equidistant manner. The angle of the internal support body 18 can be determined by the marking hole 7 corresponding to the scale groove 31 at different positions.

[0033] The two extrusion blocks 15 are both frustum-shaped on opposite sides, and the extrusion blocks 15 are rotatably connected to the extrusion plates 10 through the bearings 14. When placing the roll of paper, the connecting block 17 is pulled to separate the two extrusion plates 10, and then the roll of paper is placed at the extrusion block 15. The frustum-shaped extrusion blocks 15 can better connect with rolls of paper of different sizes. After the roll of paper is placed, the connecting block 17 is released, and the spring 11 pulls the two extrusion plates 10 toward the center to limit the roll of paper.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, when placing the roll of paper, first pull the connecting block 17, which moves the pull rod 16 in the middle of the housing 1, thereby driving the rack 13 to move. One rack 13 moves, driving the gear 12 to rotate, which in turn drives the other rack 13 to move in the opposite direction, separating the two extrusion plates 10. Then, place the roll of paper at the extrusion block 15. The frustum-shaped extrusion block 15 can better connect with rolls of paper of different sizes. After the roll of paper is placed, release the connecting block 17. The spring 11 pulls the two extrusion plates 10 toward the middle to limit the roll of paper. During use, the angle of the support body 18 is adjusted according to the thickness of the printed paper. The second grade knob 6 is used to control the rotation of the first grade knob 5. When the second grade knob 6 rotates one revolution, the first grade knob 5 rotates by 1 degree. By rotating the first grade knob 5, the second grade knob 6 is driven to rotate at a small angle, which in turn drives the support body 18 to rotate at a small angle. The angle of the internal support body 18 is determined by the marking holes 7 corresponding to the scale grooves 31 at different positions.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
