DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example 1

[0030] Reference Figure 1-9, is an embodiment of the present invention, and provides a non-sensing card knife obstacle elimination mechanism for a printer. The non-sensing card knife obstacle elimination mechanism for a printer includes a body 1 and a top cover plate 2 arranged on the top of the body 1, side bins 3 arranged on both sides of the body 1, and also includes a print motor 5 arranged on one side of the inner cavity of the body 1. The print motor 5 drives the rubber roller 12 to rotate through a transmission system. The rubber roller is in effective contact with the thermal print head, and the thermal paper is pressed between the two. When the motor drives the rubber roller 12 to move, the rubber roller 12 uses the friction between it and the TPH to drive the thermal paper to move, thereby realizing the printing process. The paper cutting motor 8 is arranged on the side of the inner cavity of the body 1 away from the printing motor 5. The paper cutting motor 8 drives the cutter to cut through its power output. This is a key step for the printer to cut the paper after completing the printing task. The stability and accuracy of the paper cutting motor 8 directly affect the quality of paper cutting. The fixed knife 13 is arranged at the top of the inner cavity of the body 1, the moving knife 14 is arranged at the top of the body 1, and the rubber roller lock shaft 17 is arranged below the fixed knife 13 on both sides of the inner cavity of the body 1, and the two ends of the rubber roller lock shaft 17 extend to the outside of the body 1, and the rubber roller 12 is arranged on the surface of the rubber roller lock shaft 17.

[0031] A paper cutting cable 7 is arranged on one side of one end of the machine body 1, a printing cable 6 is arranged on the other side of one end of the machine body 1, and a grounding plate 9 is arranged on one side of the bottom of one end of the machine body 1 away from the printing cable 6. Static electricity may be generated during the operation of the printer. If it is not released in time, it may cause damage to the electronic components inside the printer. The grounding plate 9 can be used to safely guide the static electricity that may be gathered on the printer casing into the ground, thereby protecting the device from damage by static electricity. A print head chip 10 is arranged on one end of the machine body 1. During the use of the printer, dust often accumulates inside and outside the print head. If the dust accumulates for a long time, it may enter the inside of the print head and jam the nozzle hole, thereby affecting the printing quality and printing. The print head sheet 10 can effectively prevent dust from entering the print head and keep the print head clean by covering it on the print head. A paper out detection 11 is also provided on one end of the body 1. The paper out detection 11 ensures that the printer can accurately judge the paper status, thereby avoiding printing operations in a paper out state, protecting the printer from damage, and improving printing efficiency. When the printer detects that the paper has run out or is not placed correctly, the paper out detection function will immediately send a signal to notify the printer to stop the printing job. This can effectively prevent the printer from "dry printing" in a paper out state, that is, moving and heating the print head in the absence of paper, thereby avoiding damage to the print head.

[0032] Positioning grooves 16 are provided on both sides of the top of the movable knife 14, and the positioning grooves 16 penetrate the movable knife 14, positioning sliders 15 are provided on both sides of the bottom of the top cover plate 2, and the positioning sliders 15 and the positioning grooves 16 are adapted to slide with each other, one end of the surface of the rubber roller lock shaft 17 is sleeved with a toothed button part 28, and the toothed button part 28 is located in the inner cavity of the side bin 3, an opening handle 4 is provided on the surface of the toothed button part 28, an opening toothed button 32 is provided on one side of the inner cavity of a group of side bins 3 near one end of the toothed button part 28, and the opening toothed button 32 and the toothed button part 28 are meshed with each other, and a second reset torsion spring 29 is provided in the opening toothed button 32.

[0033] A rotating shaft 18 is provided on both sides of the inner cavity of the body 1, and both ends of the rotating shaft 18 extend to the inner cavity of the side bin 3, second rotating gears 26 are provided at both ends of the surface of the rotating shaft 18, a second transmission gear 25 is provided on one side of a group of second rotating gears 26, and the second transmission gear 25 is sleeved on the surface of the rotating shaft 18, and racks 27 are provided on both sides of the bottom of the movable knife 14, and the racks 27 and the second rotating gears 26 are meshed with each other.

[0034] One side of the inner cavity of a group of side bins 3 is rotatably connected to a limiting sleeve shaft 19, a knife retracting tooth 21 is arranged on the surface of the limiting sleeve shaft 19, a knife retracting rotating bracket 20 is arranged on the surface of the knife retracting tooth 21, a first reset torsion spring 22 is arranged on the surface of the limiting sleeve shaft 19, and the first reset torsion spring 22 is located in the inner cavity of the knife retracting tooth 21, a limiting collar 30 is arranged on one side of the knife retracting rotating bracket 20, and a third reset torsion spring 31 is arranged in the knife retracting rotating bracket 20, the surface of the limiting collar 30 is sleeved with a first rotating gear 23, a first transmission gear 24 is arranged on one side of the first rotating gear 23, and the first transmission gear 24 and the second transmission gear 25 are meshed with each other.

[0035] During use, when the movable knife 14 driven by the rack 27 is normally driven to return to the origin on the machine body 1, in this case, the knife jamming obstacle structure is excluded when the cover opening handle 4 is pressed to open the magazine for paper replacement normally, and normal use is not affected. When the movable knife 14 driven by the rack 27 fails to automatically return to its original position due to abnormal driving on the machine body 1, the cover opening handle 4 is pressed to move the tooth button member 28, so that the cover opening tooth button 32 meshing with the tooth button member 28 moves, and the second reset torsion spring 29 is compressed, and then the knife retracting tooth 21 is driven to move upward, and the first reset torsion spring 22 is compressed, thereby driving the limiting ring 30 on the knife retracting rotating bracket 20 to rotate, and driving the first The rotating gear 23 rotates and the first transmission gear 24 rotates, and then the second rotating gear 26 and the second transmission gear 25 are meshed with each other, and then the second transmission gear 25 rotates synchronously, thereby driving the second rotating gear 26 to rotate. At the same time, the second rotating gear 26 and the rack 27 are meshed with each other, thereby driving the movable knife 14 to move. Then, the cover opening handle 4 is released and the resilience of the second reset torsion spring 29 and the first reset torsion spring 22 can be used to reset the cover opening handle 4, thereby making the second rotating gear 26 rotate in the opposite direction, so that the movable knife 14 moves in the opposite direction, and then the cover opening handle 4 is repeatedly pressed, and the movable knife 14 will be gradually pulled back to the origin, thereby realizing the seamless elimination of the movable knife 14 jam.
