Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , in the embodiment of the present utility model, a test paper printing and renovation printer includes a printer main body 1 for test paper printing, and a test paper renovation component 4 is movably connected above the printer main body 1;

[0026] The described test paper renovation component 4 includes a movable bottom frame 41, and an upper cover body 45 is also movably connected above the movable bottom frame 41; a concave cavity is provided at the bottom of the upper cover body 45, and a lateral movement component 46 and a longitudinal movement component 47 for facilitating the horizontal and vertical movement of the laser 48 are provided in the concave cavity, wherein the laser 48 is cooperatively connected with the longitudinal movement component 47; a protective shell 49 is integrally provided at the top of the upper cover body 45, and there is a cavity between the protective shell 49 and the upper cover body 45 for facilitating the entry of the test paper, and a test paper scanner 410 is provided inside the cavity.

[0027] Specifically, a through groove is provided at one end of the upper cover body 45, and a paper feeding roller 411 is provided in the through groove; a flat motor is provided at one end of the paper feeding roller 411.

[0028] By adopting the above technical solution, when in use, first place the used test paper into the cavity between the protective shell 49 and the upper cover body 45, scan it through the scanner 410, and transmit the scanned information to the control system of the printer;

[0029] The control system consists of a control unit and a data analysis unit. The data analysis unit analyzes the scanned images, discriminates which are printed fonts and which are handwritten fonts, and marks the handwritten fonts.

[0030] Subsequently, the test paper is transported between the movable bottom frame 41 and the upper cover 45 by the paper feed roller 411. With the cooperation of the lateral movement component 46 and the longitudinal movement component 47, the laser 48 can move freely horizontally and vertically. Then, the handwritten words are eliminated by the laser 48. The laser beam irradiates on the handwriting, causing physical and chemical changes such as decomposition and gasification of the ink or dye on the handwriting, so as to be eliminated.

[0031] The laser 48 is a carbon dioxide laser or a semiconductor laser, ensuring that the wavelength and energy of the laser can effectively eliminate the handwriting. The laser 48 also has a laser power regulator, which can adjust the power of the laser according to the type of handwriting and the material of the paper to avoid excessive damage to the paper.

[0032] The control system uses a microprocessor as the core of the control system, receives the handwriting information transmitted by the scanner, and controls the laser 48 to perform precise irradiation.

[0033] In this embodiment, a transmission groove 42 is further opened on the upper end surface of the movable bottom frame 41. A plurality of paper transmission rollers 43 are arranged in the transmission groove 42, and a paper outlet 44 communicating with the transmission groove 42 is opened on one side of the movable bottom frame 41. A transmission component (not shown) is arranged outside one of the plurality of paper transmission rollers 43, and the plurality of paper transmission rollers 43 are connected by a belt.

[0034] By adopting the above technical solution, after the laser eliminates the handwritten words, the plurality of paper transmission rollers 43 transport the test paper out from the paper outlet 44.

[0035] In this embodiment, a storage groove 2 is opened on one side of the upper surface of the printer main body 1. A telescopic hinge 3 is movably connected in the storage groove 2 through a rotating shaft; the other end of the telescopic hinge 3 is movably connected to the movable bottom frame 41.

[0036] By adopting the above technical solution, through the setting of the telescopic hinge 3 and the storage groove 2, the free movement between the printer main body 1 and the test paper renovation component 4 can be realized, and the test paper renovation component 4 can be used alone or printing can be performed through the printer main body 1.

[0037] In this embodiment, a positioning card slot 5 is further opened on one side of the upper surface of the printer main body 1 away from the storage groove 2. A positioning buckle is arranged in the positioning card slot 5, and the positioning buckle is cooperatively installed at the bottom of the movable bottom frame 41.

[0038] The working principle of the present utility model is as follows: when in use, first place the used test paper into the cavity between the protective shell 49 and the upper cover body 45, scan it through the scanner 410, and transmit the scanned information to the control system of the printer;

[0039] The control system consists of a control unit and a data analysis unit. Among them, the data analysis unit analyzes the scanned image, discriminates which are printed fonts and which are handwritten fonts, and marks the handwritten fonts;

[0040] Subsequently, the test paper is transmitted between the movable bottom frame 41 and the upper cover body 45 through the paper feed roller 411. With the cooperation of the transverse movement assembly 46 and the longitudinal movement assembly 47, the laser 48 can move freely horizontally and vertically; then the handwritten words are eliminated by the laser 48; the laser beam irradiates on the handwriting, causing physical and chemical changes such as decomposition and gasification of the ink or dye on the handwriting, so as to be eliminated.

[0041] The laser 48 is a carbon dioxide laser or a semiconductor laser, ensuring that the wavelength and energy of the laser can effectively eliminate the handwriting; the laser 48 also has a laser power regulator, which can adjust the power of the laser according to the type of handwriting and the material of the paper to avoid excessive damage to the paper.

[0042] The control system uses a microprocessor as the core of the control system, receives the handwriting information transmitted by the scanner, and controls the laser 48 to perform precise irradiation.

[0043] After the handwritten words are eliminated by the laser, multiple paper transmission rollers 43 transmit the refurbished test paper from the paper outlet 44.

[0044] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
