Description

Technical Field

[0001] The utility model relates to the field of printer technical equipment, and particularly relates to a paper output cooling device for a printer. Background Technique

[0002] A printer, also known as a printing machine, is a computer output device that can permanently output the data stored in a computer in the form of text or graphics onto paper or transparent film. There are many types of printers. According to whether the printing element has a striking action on the paper, it can be divided into: impact printers and non-impact printers. Nowadays, printing equipment has become an essential device in public places such as companies and schools. The existence of printing equipment can more intuitively display Chinese culture in front of people, be able to print the text on the Internet onto paper, which is convenient for readers to view and protects the readers' eyesight.

[0003] After retrieval, the utility model patent with the publication number of CN109573708A and the name of "a printing device for sorting paper" discloses a printing device for sorting paper, including a printer main body, a U-shaped backing plate, a cylinder, a push rod, a sorting plate, a water tank, a refrigerator, a water pump, and an S-shaped heat conduction pipe. The U-shaped backing plate is installed on the right end face of the printer main body, the cylinder is fixed on the upper end face of the U-shaped backing plate, the push rod is arranged on the left end face of the cylinder, the sorting plate is fixed on the left end face of the push rod, there is a sorting plate on the upper end face of the U-shaped backing plate, and the push rod is arranged above the U-shaped backing plate. This design realizes the function of automatically sorting paper. The water tank is installed on the front end face of the printer main body, the refrigerator is arranged at the bottom end inside the water tank, the water pump is installed on the left inner wall of the water tank, the S-shaped heat conduction pipe is arranged at the right end of the water pump, and the S-shaped heat conduction pipe is installed on the front end face of the printer main body. This design realizes the cooling function. The utility model realizes the function of automatically sorting paper and the cooling function, with strong practicability and high reliability.

[0004] The above technical solution realizes the functions of temperature reduction and paper sorting, can quickly reduce the temperature of the printer body, ensure the working efficiency of the printer, and make the fonts on the printed paper clearer. However, this temperature reduction function only targets the printer body and cannot be applied to the printed paper itself. In the actual use process, the fixing of a laser printer is a process of melting the toner attached to the printing paper by means of pressurization and heating and immersing it into the printing paper to form a firm graphic on the paper surface. The main component of the toner is resin, the melting point of the toner is about 100 °C, and the temperature of the heating roller of the fixing assembly is about 180 °C. The printed paper needs to pass through the heating roller for fixing. After fixing, it is overheated. When the user picks up the printed paper, it is very likely to cause scalding of the hand, which is likely to cause the font to be blurred and the user experience is poor. At the same time, when double-sided printing is required for the paper, due to the temperature resistance problem of the toner cartridge during printing, after the first side of the paper is printed and fixed, the temperature is very high and it cannot be quickly reversed to the toner cartridge to print the second side. When double-sided printing is performed, after the first side is printed, the cooling time of the paper is relatively long, affecting the double-sided printing efficiency.

[0005] In summary, there is an urgent need for a printer paper output cooling device to solve the above problems. Utility Model Content

A paper output cooling device of a printer shown in the present utility model is provided with a paper finishing mechanism including a heating roller and a first pressing roller; a cooling mechanism including a refrigeration roller and a second pressing roller; the paper finishing mechanism is arranged on one side of the cooling mechanism. During operation, the printed paper will first pass through the paper finishing mechanism for fixing, and then pass through the cooling mechanism for cooling. When the printed paper passes through the refrigeration roller, the temperature of the paper can be quickly cooled to room temperature, with a comfortable hand feeling temperature and no harm to the human body.
