detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 to 3, the drying device for the inkjet printing device in the present invention is arranged at the paper output end of the inkjet printing device, and the drying device includes a first drying mechanism 1 and a second drying mechanism 2, In the process of inkjet printing, the first drying mechanism 1 and the second drying mechanism 2 are arranged in parallel along the front and rear direction (paper feeding direction), and the printing medium with ink droplets attached passes through the first drying mechanism 1 and the second drying mechanism. After the drying area formed by mechanism 2, it is rolled up by the paper delivery mechanism.

The first drying mechanism 1 is fixedly installed on the base bracket of the printing device, specifically, one end of the first drying mechanism 1 is installed on the left side plate 11 of the base bracket, and the other end of the first drying mechanism 1 is installed on the base On the right side plate 12 of support. The first drying mechanism 1 of the present invention includes a drying support and at least two fans installed on the drying support to uniformly distribute the printing width. In the utility model, the number of fans installed in the first drying mechanism is proportional to the printing width, and the wider the printing width, the more fans are installed in the first drying mechanism.

In order to make the drying speed faster, the first drying mechanism of the utility model can be set to include a drying bracket, at least two fans evenly distributed on the drying bracket and a heating device installed on the drying bracket, and the fan blows out After passing through the heating device, the wind is used to dry the printing medium on which the image is jetted and printed. The utility model can also make the drying speed faster by increasing the area of the drying area, that is, the first drying mechanism is set as two, three or more drying supports arranged in the vertical direction. Fans with multiple printing widths are evenly distributed on the bracket.

The lower end of the second drying mechanism 2 is hingedly mounted on the base support of the printing device, and the second drying mechanism can rotate around the hinged part of the lower end. The lower end of the second drying mechanism 2 in the utility model can also be installed on the base bracket through the rotating shaft, and the second drying mechanism can rotate around the rotating shaft. The upper end of the second drying mechanism 2 is connected with the upper end of the first drying mechanism through the chain 3, and the rotation angle of the second drying mechanism is limited by setting the length of the chain. The longer the chain 3 is, the larger the rotation angle between the second drying mechanism 2 and the first drying mechanism 1 is.

A locking block 22 is respectively arranged on both sides of the upper end of the second drying mechanism 2 , and a locking elastic latch 5 is arranged on the base support at a position corresponding to the locking block 22 . When loading paper before inkjet printing, the locking elastic pin 5 is not in contact with the locking block 22, and the first drying mechanism 1 and the second drying mechanism 2 are in an open state, so that the printing medium can pass through the first drying mechanism 1 and the second drying mechanism 2 are then connected to the delivery mechanism; during inkjet printing, the locking elastic bolt 5 cooperates with the locking block 22, and the latch of the locking elastic bolt 5 is inserted into the locking hole on the locking block 22 , so that the first drying mechanism 1 and the second drying mechanism 2 are arranged in parallel to form a drying area for the printing medium, so as to reduce the heat loss of the drying device and improve the drying efficiency and drying speed.

According to printing requirements, the first drying mechanism and the second drying mechanism in the drying device of the present invention have the same structure. The first drying mechanism and the second drying mechanism in the drying device of the present utility model can also be different structures, such as being provided with a heating device on the first drying mechanism when the printing speed is low for energy saving, and the second There is no heating device on the drying mechanism; or the first drying mechanism uses heating wire for heating, while the second drying mechanism uses far-infrared heating. This kind of drying device is suitable for more Drying operation for various inks.
