Description

Technical Field

[0001] The utility model relates to the field of inkjet printing equipment, in particular to a drying device for inkjet printing of an inkjet printer. Background Art

[0002] Inkjet printer refers to a device that uses digital printing technology to transmit and transfer images. It uses photoelectric sensing technology, inkjet technology and other means to output computer digital images to the corresponding media for image output and production. The ink sprayed by the nozzle is used to print paintings, advertisements and pure color patterns on various materials.

[0003] However, since the ink is in liquid form, the ink will not dry and solidify immediately on the printing material after being sprayed. Especially when spraying large paintings, the ink is even more difficult to dry. If the sprayed products are stacked together immediately, the pattern or number of the sprayed products will be blurred. When the printing medium is rolled up after the spraying is completed, the ink will also stick to the back of the printing medium, affecting the use. The drying device of the inkjet printer in the prior art is mostly installed inside the machine body, and the heat generated by the drying device greatly increases the temperature of the inkjet printer, affecting the stability and service life of the inkjet printer. In addition, the temperature generated by the drying device of the inkjet printer in the prior art will cause the printed paper to deform and wrinkle, which is inconvenient for subsequent rolling and sorting.

[0021] In the following description, references to "one embodiment", "an embodiment", "an example", "an example", etc. indicate that the embodiment or example described in this way may include specific features, structures, characteristics, properties, elements or limitations, but not every embodiment or example necessarily includes the specific features, structures, characteristics, properties, elements or limitations. In addition, repeated use of the phrase "according to one embodiment of the present application" may refer to the same embodiment, but does not necessarily refer to the same embodiment.

[0022] like Figure 1 As shown, it includes a chassis 1, a feed port 9 is opened on the left side of the chassis 1, a discharge port 10 is opened on the right side of the chassis 1, a plurality of rotating rollers 6 are arranged at intervals from left to right in the chassis 1, a flattening roller component 7 is arranged above the rotating roller 6 near the discharge port 10, the rotating roller 6 and the flattening roller component 7 are connected by a transmission belt 13, a heating chamber 5 is arranged on the top of the chassis 1, and a fan 4 is connected to the outside of the heating chamber 5, and the flatness of the inkjet material is ensured by the cooperation of the rotating roller 6 and the flattening roller component 7. The model of the fan 4 is KT4D, which is a prior art and will not be described in detail.

[0023] A first air inlet duct 21 is provided at the bottom of the front end of the chassis 1, and a second air inlet duct 22 is provided at the bottom of the rear end of the chassis 1. By respectively providing the first air inlet duct 21 and the second air inlet duct 22 at the front and rear ends of the chassis 1, it is ensured that the material to be dried is subjected to balanced force and thus heated evenly, thereby improving the drying effect and avoiding the material to be dried from tilting. A filter chamber 3 is provided at the top of the heating chamber 5, and the first air inlet duct 21 and the second air inlet duct 22 are connected to the filter chamber 3. An activated carbon filter 31 is provided inside the filter chamber 3. The left side of the filter chamber 3 is connected to the fan 4, and the volatile organic compounds (VOCs) generated during the drying process are adsorbed by the activated carbon filter 31.

[0024] The front and rear walls inside the chassis 1 are longitudinally provided with guide plates 11 , which include a slope 15 , and the included angle of the slope 15 is 20°-30°. The guide plates 11 guide the hot air above to the material to be dried.

[0025] The flattening roller component 7 includes a first flattening roller 71 and a second flattening roller 72. The second flattening roller 72 is located above the rightmost rotating roller 6, and the first flattening roller 71 is located above the right rotating roller 6. The distance between the first flattening roller 71 and the rotating roller 6 below is twice the distance between the second flattening roller 72 and the rotating roller 6 below. The flattening roller component 7 cooperates with the rotating roller 6 below to smooth the materials that are wrinkled and deformed during the drying process.

[0026] Adjacent rotating rollers 6 are connected by a transmission belt 13, the rightmost rotating roller 6 is connected to the second flattening roller 72 by a transmission belt 13, the second flattening roller 72 is connected to the first flattening roller 71 by a transmission belt 13, and the rightmost rotating roller 6 passes through one end of the chassis 1 and is provided with a drive motor 8, and a support frame 81 is provided below the drive motor 8. The model of the drive motor 8 is Y180M-2, which is the prior art and will not be elaborated on. The rotating roller 6 and the flattening roller component 7 are driven to rotate by the transmission belt 13, and the transmission and flattening of the material to be dried are realized by a drive motor 8, thereby reducing the cost of the device and the difficulty of maintenance.

[0027] A plurality of heating rods 51 are arranged at intervals in the heating chamber 5, and a plurality of air outlets 14 are arranged at intervals and penetrate the chassis 1 below the heating chamber 5. The heating rods 51 in the heating chamber 5 heat the air brought by the fan 4, and the air enters the chassis 1 through the discharge port 10, and directly dries the material to be dried through the front and rear guide plates 11 in the chassis 1.

[0028] The cross section of the feed port 9 is a trapezoidal interface, and the cross section of the discharge port 10 is a trapezoidal interface. By setting the feed port 9 and the discharge port 10 to be wide in and narrow out, on the one hand, the difficulty of alignment of the materials to be dried by the workers is reduced, and on the other hand, the volatile organic compounds (VOCs) in the chassis 1 are reduced from entering the outside through the feed port 9 and the discharge port 10, thereby protecting the workers' physical safety.

[0029] Working process: turn on the driving motor 8, the fan 4 and the heating chamber 5, then put the material to be dried into the material feed port 9, move to the right through the rotating roller 6, and the fan 4 blows the wind in the filter chamber 3 to the heating chamber 5. After being heated by the heating rod 51 in the heating chamber 5, the wind enters the chassis 1 through the air outlet 14. The heated wind flows directly to the material to be dried through the guide plate 11, and then flows to the first air inlet pipe 21 and the second air inlet pipe 22 through the gap between the rotating roller 6 and the front and rear ends of the chassis 1. The hot air enters the filter chamber 3 and passes through the activated carbon filter 31 to complete the adsorption of volatile organic compounds (VOCs) generated during the drying process, and then is blown to the heating chamber 5 through the fan 4. After that, the material is leveled by the flattening roller component 7 and discharged from the discharge port 10.
