Thermal retroflex energy-saving printer

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0031] see Figures 1 to 6 , is a thermal rewinding energy-saving printer as a preferred embodiment of the present invention, comprising a printer body, a paper bin 10 for placing paper rolls and a paper feeding channel 20 for paper movement in the printer body; paper feeding; The channel 20 is provided with a reverse winding portion 21 opposite to the wrapping direction of the paper roll near the paper magazine 10, that is, the wrapping direction of the paper is first in an "S" shape, and then passes through the channel between the printing rubber roller 30 and the thermal print head, Realize the paper output tends to be flat; a heating device for heating the paper in the rewinding curved part 21 is arranged in the main body of the printer; the rewinding curved part 21 cooperates with heating to realize the thermal shaping of the paper, avoiding springback and making the bending The paper is more flat and the printing quality is improved.

[0032] The printer body is provided with a printing rubber roller 30 and a motor 40 for driving the printing rubber roller 30 to rotate. The heating device adopts a heat recovery block 50 which is in contact with the outer surface of the motor 40 and is used for recovering the heat energy generated by the motor 40, and the heat energy collected by the heat recovery block 50 is used to heat the paper. The heat recovery block 50 includes a recovery part 51 attached to the outer surface of the motor 40 , and a heating part 52 connected to the recovery part 51 and used for heating the paper. The use of the motor 40 to generate heat energy cooperates with the rewinding part 21 to realize the rewinding function, and realizes the shaping function of the paper; therefore, by transferring the harmful heat energy of the excess motor 40 and recycling it for the second time, the service life of the provided product can be improved and the performance can be improved. It is greatly improved, and the advantages of energy saving, environmental protection and waste reduction are achieved.

[0033] The main body of the printer includes an upper assembly 60 and a lower assembly 70 which are rotatably connected on one side. The upper assembly 60 and the lower assembly 70 form a paper bin 10 and a paper feeding channel 20 . The upper assembly 60 is also provided with a rotating shaft 64 for changing the direction of the paper, and the lower assembly 70 is provided with a groove 721 for the rotating shaft 64 to be embedded, and a rewinding curved portion 21 is formed between the rotating shaft 64 and the groove 721 . The bottom of the groove 721 is provided with a long hole 7211 for the heat recovery block 50 to pass through; specifically, the heating block enters the groove 721 through the long hole 7211 to heat the paper.

[0034] The upper assembly 60 includes an upper casing 61 and an upper bracket 62 arranged inside the upper casing 61 , the lower assembly 70 includes a lower assembly 70 whose lower casing 71 has been arranged inside the lower casing 71 , and the printing rubber roller 30 and the motor 40 are arranged On the lower bracket 72, and the motor 40 is located between the lower casing 71 and the lower bracket 72, the upper assembly 60 is also disposed on the upper bracket 62 and is used to limit the thermal print head. The fixed cover 63, the rotating shaft 64 and the fixed cover 63 / The upper bracket 62 is rotatably connected, and the groove 721 is arranged on the lower bracket 72 .

[0035] The fixed cover 63 is provided with two support columns 631 for inserting the rotating shaft 64 into the groove 721, and both ends of the rotating shaft 64 are rotatably connected to the supporting columns 631; By means of transition fit, in the process of paper feeding, the rotating shaft 64 can also be rotated to make the paper feeding more smoothly; the two ends of the rotating shaft 64 are provided with C-shaped buckles 65 that restrict it to the two support columns 631; specifically, The C-shaped buckles 65 are located outside the two support columns 631 , and the rotating shaft 64 is provided with an annular groove for matching with the C-shaped buckles 65 .

[0036] Since the diameter of the rotating shaft 64 is selected to be small in order to realize that the external dimensions of the thermal printer do not change, in order to avoid bending during the rotation, the fixed cover 63 and located between the two supporting columns 631 are provided with a bearing for bearing against the rotating shaft 64. The support part 632; the support part 632 is provided with an arc-shaped groove 6321 which is matched with the outer surface of the rotating shaft 64.

[0037] To sum up, the energy-saving printer of the present invention realizes thermal shaping of the paper by setting the rewinding curved part opposite to the wrapping direction of the paper roll, and cooperates with the heating device for heating the paper, and the rewinding curved part cooperates with heating to realize the thermal shaping of the paper, so that the bending The paper is more flat and the printing quality is improved; and by heating the paper, the printer can effectively prevent the printer from printing light and blurry, and the printing quality drops sharply when the ambient temperature is too low in winter.

[0038] The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements made by the method concept and technical solutions of the present invention are adopted, or no improvement is made. It is within the protection scope of the present invention to directly apply the concepts and technical solutions of the present invention to other occasions.
