Description

Technical Field

[0001] The invention relates to a printer structure, and in particular to a printer with a laminating function. Background Art

[0002] In today's offices, when documents or photos need to be laminated, a laminating machine is usually required to perform the laminating operation. The laminating machine mainly uses heating to make the laminating film adhere to the paper, and the upper and lower rollers apply pressure to press the laminating film.

[0003] However, the usage rate of laminating machines is low, resulting in low willingness to purchase and poor space utilization. In addition, laser printers have heating components and pressure rollers inside to melt the toner and fix it on the paper. Therefore, how to make laser printers have laminating functions and thus eliminate the need to purchase laminating machines is an important issue in the industry.

[0004] In view of this, the present invention focuses on the above-mentioned prior art, conducts intensive research and applies theoretical knowledge to try its best to solve the above-mentioned problems, which becomes the goal of the present invention. Summary of the invention

[0005] The invention provides a printer with a laminating function, which controls the heating temperature and pressing pressure of a pressurizing heating module after receiving a film signal by a processing unit, so as to achieve the advantage of the printer having the convenience of laminating.

[0006] In an embodiment of the present invention, the present invention provides a printer with a laminating function, which is used for a laminating film. The printer includes: a printer body, having a printing channel, a paper inlet connected to the printing channel, and a paper tray and a paper pickup wheel group configured corresponding to the paper inlet, wherein the laminating film is sequentially transported from the paper tray and the paper inlet to the printing channel through the paper pickup wheel group; a pressurizing and heating module, which is installed in the printing channel, and is used to heat and press the laminating film; a film sensor, which is installed in the printer body and is configured corresponding to at least one of the paper inlet and the paper tray, and the film sensor generates a film signal when sensing the laminating film; and a processing unit, which is electrically connected to the pressurizing and heating module and the film sensor, and controls the heating temperature and pressing pressure of the pressurizing and heating module after receiving the film signal.

[0007] Based on the above, the pressurized heat module of the printer is mainly used to melt the toner and fix it on the paper, so the temperature and pressure usually set by the pressurized heat module are not suitable for laminating film bonding. Therefore, the laminating film is sensed by the film sensor and a film signal is generated. After receiving the film signal, the processing unit controls the pressurized heat module to heat to the film bonding temperature and press to the film pressing pressure, so as to achieve the advantages of the printer having pre-set laminating parameters and convenient laminating.

[0032] The technical content and detailed description of this application are described below with reference to the accompanying drawings:

[0033] Please refer to Figures 1 to 5 As shown, the present invention provides a printer with a laminating function. The printer 10 mainly includes a printer body 1, a pressurizing and heating module 2, a film sensor 3 and a processing unit 6.

[0034] The printer 10 of the present invention is used for a laminating film 100 and a paper 200. The laminating film 100 is folded up and down in a manner of being connected at one end and separated at the other end. The paper 200 is placed in the laminating film 100 folded up and down, and the laminating film 100 folded up and down is intertwined to laminate the paper 200. The laminating film 100 is formed by coating ethylene vinyl acetate (EVA) adhesive inside a polyethylene terephthalate (PET) film.

[0035] like Figures 1 to 3 As shown, the printer body 1 has a printing channel (not shown), a paper inlet 11 connected to the printing channel (not shown), and a paper tray 12 and a paper pickup wheel set 13 corresponding to the paper inlet 11. The laminating film 100 is sequentially transported from the paper tray 12 and the paper inlet 11 to the printing channel (not shown) by the paper pickup wheel set 13. The paper tray 12 of this embodiment is an external paper feed tray 121, but it is not limited thereto.

[0036] like Figures 1 to 3 As shown, the printer 10 of this embodiment is a laser printer. The laser printer has a printing module (not disclosed) for adsorbing toner on paper and a fuser (Fuser) for melting toner and fixing it on paper. The fuser is the pressurized heat module 2 of the present invention. The printing module (not disclosed) and the pressurized heat module 2 are installed in a printing channel (not disclosed), and the printing module (not disclosed) is arranged between the paper feed tray 12 and the pressurized heat module 2, so that the laminating film 100 is guided by the paper pickup wheel set 13 and the printing channel (not disclosed) to first pass through the printing module (not disclosed) and then pass through the pressurized heat module 2.

[0037] In addition, the pressurized heat module 2 includes a pressurizing roller 21 and a heating roller 22 that jointly clamp the laminating film 100. The pressurizing roller 21 can adjust the pressure against the heating roller 22. The heating roller 22 has a heater 23. The temperature of the heating roller 22 can be adjusted by the heater 23 so that the pressurized heat module 2 is used to heat and press the laminating film 100.

[0038] Among them, in this embodiment, only the heating roller 22 has a heater 23, and the pressure roller 21 does not have a heater. The pressurized heat module 2 composed of the pressure roller 21 and the heating roller 22 is a common fixing device, but this is not a limitation. The pressurized heat module 2 of the present invention may not be a fixing device, and the pressure roller 21 may have a heater so that the temperature of the pressure roller 21 can be adjusted by the heater.

[0039] like Figures 1 to 3 , Figure 5 As shown, the film sensor 3 is installed on the printer body 1 and is disposed corresponding to at least one of the paper inlet 11 and the paper tray 12. The film sensor 3 senses the laminating film 100 and generates a film signal.

[0040] The detailed description is as follows. The film sensor 3 of this embodiment is installed on one side of the paper picking wheel assembly 13, and the film sensor 3 can be set corresponding to the paper inlet 11, or corresponding to one end of the paper tray 12 adjacent to the paper inlet 11. When the paper 200 is placed in the laminating film 100 for laminating, the paper 200 is placed in the middle of the laminating film 100, and the edge is left for the edge of the laminating film 100 to be bonded to complete the laminating. By utilizing the great difference in the reflectivity of the paper 200 to light and the reflectivity of the laminating film 100 (which is more transparent so that the contents of the laminating can be seen) to light, the film sensor 3 can easily sense the edge of the laminating film 100 that does not overlap with the paper 200, and then when the film sensor 3 senses the edge of the laminating film 100, it can accurately determine that it is made of laminating film material, so as to improve the sensing accuracy of the film sensor 3.

[0041] like Figures 1 to 5 As shown, the processing unit 6 is installed on the printer body 1 and is electrically connected to the paper picking wheel assembly 13, the pressurized heating module 2, the film sensor 3 and the display screen (not shown) of the printer body 1. After receiving the film signal, the processing unit 6 controls the heating temperature and the pressing pressure of the pressurized heating module 2. It is further explained as follows: after receiving the film signal, the processing unit 6 controls the heating roller 22 to heat to a film bonding temperature that can melt the glue on the laminating film 100, and the pressurized roller 21 applies a film pressing pressure to the heating roller 22 to pressurize and bond the glue on the laminating film 100.

[0042] like Figures 1 to 4 As shown, the printer 10 of the present invention further includes an object sensor 4, which is installed on the top surface of the paper tray 12. When the object sensor 4 senses that a laminating film 100 or a paper 200 is placed in the paper tray 12, an object signal is generated.

[0043] In addition, the film sensor 3 and the object sensor 4 are photoelectric sensors composed of an infrared transmitting tube and an infrared receiving tube. The material detection is achieved by converting the intensity change of light between the transmitting end and the receiving end into the change of current. That is, the different absorption and reflectivity of light by the sensing objects of different materials cause the received current signal to be different, thereby knowing the material of the sensing object.

[0044] like Figures 1 to 4 As shown, the printer 10 of the present invention further includes a lifting mechanism 5 to ensure that the paper 200 placed in the laminating film 100 and the laminating film 100 can be smoothly and accurately delivered to the paper inlet 11 for laminating. The lifting mechanism 5 is installed on the paper feed tray 12, and the processing unit 6 is electrically connected to the object sensor 4 and the lifting mechanism 5. After receiving the object signal, the processing unit 6 controls the lifting mechanism 5 to lift the laminating film 100 and guide the laminating film 100 into the paper inlet 11.

[0045] Among them, the lifting mechanism 5 of this embodiment is a liftable inclined plate 51 installed on the top surface of the paper feed tray 12, and the liftable inclined plate 51 is lifted to push the laminated film 100 into the paper feed port 11, but it is not limited to this. The lifting mechanism 5 can also be installed at the bottom of the paper feed tray 12. The lifting mechanism 5 lifts one end of the paper feed tray 12 away from the paper feed port 11, making the elevation angle of the paper feed tray 12 more inclined, so that the top surface of the paper feed tray 12 is inclined and the laminated film 100 is pushed into the paper feed port 11.

[0046] like Figures 2 to 5 As shown, the printer 10 of the present invention is in use. When the laminating film 100 is placed in the paper feed tray 12, the object sensor 4 senses the laminating film 100 and other documents and generates an object signal. After receiving the object signal, the processing unit 6 controls the lifting mechanism 5 to lift the laminating film 100 and guide the laminating film 100 into the paper feed port 11.

[0047] Afterwards, the film sensor 3 senses that the laminating film 100 will generate a film signal. After receiving the film signal, the processing unit 6 controls the heating roller 22 to heat to a film bonding temperature that can melt the glue on the laminating film 100, and the pressure roller 21 applies a film pressing pressure to the heating roller 22 to press the glue on the laminating film 100 to bond, that is, controls the pressurizing heating module 2 to heat to the film bonding temperature and pressurize to the film pressing pressure.

[0048] Finally, the print start button is pressed on the display screen of the printer body 1, and the processing unit 6 controls the paper pick-up wheel group 13 to feed the laminating film 100 into the printing channel (not shown). At this time, the pressurizing and heating module 2 has been preheated to a temperature at which the laminating film 100 can be stably heated and bonded, so as to avoid the laminating film 100 being atomized due to the heating temperature being too low or the laminating film 100 being generated with bubbles due to the heating temperature being too high. At the same time, the pressurizing and heating module 2 will also apply a pressure suitable for the laminating film 100 to be tightly pressed, thereby completing the laminating film 100 bonding and laminating the paper 200.

[0049] Thus, since the pressurized heat module 2 of the printer 10 is mainly used for melting and fixing carbon powder on paper, the temperature and pressure usually set by the pressurized heat module 2 are not suitable for bonding the laminating film 100. Therefore, the laminating film 100 is sensed by the film sensor 3 and a film signal is generated. After receiving the film signal, the processing unit 6 controls the pressurized heat module 2 to heat to the film bonding temperature and press to the film pressing pressure, so that the printer 10 has the advantages of pre-setting laminating parameters and convenient laminating.

[0050] In summary, the printer with laminating function of the present invention has never been seen in similar products and has never been used publicly. The above description is only a preferred embodiment of the present application, and should not limit the scope of implementation of the present application. That is, all equivalent changes and modifications made according to the present application should still fall within the scope of the patent coverage of the present application. The present application may also have other various embodiments. Without departing from the spirit and essence of the present application, technicians familiar with the art can make various corresponding changes and deformations according to the present application, but these corresponding changes and deformations should fall within the scope of protection of the claims attached to the present application.
