Description

Technical Field

[0001] The present application relates to the field of drying technology for inkjet printers, and particularly to a drying device for an inkjet printer. Background Art

[0002] An inkjet printer is a device that uses software control to identify products in a non-contact manner. The inkjet printer works on the principle of deflecting charged ink particles through a high-voltage electric field to print patterns, texts, and digits on the surfaces of various objects, and it is widely used in fields such as the food industry, cosmetics industry, pharmaceutical industry, automotive parts processing industry, wire and cable industry, and aluminum-plastic pipe industry.

[0003] To improve the packing and processing efficiency of products, a drying device is required to dry the products processed by the inkjet printer. The existing drying devices have problems of low drying efficiency and unstable drying effect when drying products of different heights. When the drying device is far from the product, the drying efficiency of the product is low and the drying effect is poor, thus reducing the packing efficiency of the product; when the drying device is close to the product, the un-dried ink will move due to strong wind, thus reducing the quality of the sprayed pattern.

[0004] In view of the above related technologies, the inventor believes that the drying device of the inkjet printer has problems of low drying efficiency and unstable drying effect. Utility Model Content

[0005] To solve the above technical problems, the present application provides a drying device for an inkjet printer.

[0006] The drying device for an inkjet printer provided by the present application adopts the following technical solutions:

[0007] A drying device for an inkjet printer includes a conveying component, a drying mechanism, and a height adjustment component; the drying mechanism includes a heating cover, a blowing component arranged in the heating cover, a heating component arranged inside the heating cover, and a ventilation plate arranged at one end of the heating cover close to the conveying component, and a plurality of ventilation holes are formed in the ventilation plate; the height adjustment component includes a base, a first driving motor arranged on the base, a lead screw fixedly connected to the transmission shaft of the first driving motor, a first connecting block threadedly connected to the lead screw, a limiting rod arranged on the base, and a second connecting block, the second connecting block is slidably connected to the limiting rod, and both the first connecting block and the second connecting block are connected to the heating cover.

[0008] By adopting the above technical solution, the conveying component conveys the product to the lower part of the drying mechanism. The first driving motor drives the lead screw to rotate. The limiting rod and the second connecting block limit the heating cover. The first connecting block drives the heating cover to move up and down, thus realizing the height adjustment of the drying mechanism, facilitating the drying mechanism to be applicable to products of different heights, and thus improving the drying efficiency and quality of the drying mechanism. The blowing component provides drying air, and the heating component heats the drying air, thereby improving the drying efficiency of the drying air on the product.

[0009] Preferably, the heating component includes a heating wire connected to the heating cover, and the heating wire is in an arc structure.

[0010] By adopting the above technical solution, the heating wire in an arc structure increases the contact area between the drying air and the heating component, thereby improving the heating effect of the heating component on the drying air, and further improving the drying efficiency of the drying mechanism on the product.

[0011] Preferably, a heat insulation layer is provided on the inner wall of the heating cover.

[0012] By adopting the above technical solution, the setting of the heat insulation layer reduces the heat loss in the heating cover, thereby improving the heating effect of the heating component on the drying air, and further improving the drying efficiency of the drying mechanism on the product.

[0013] Preferably, the ventilation plate is in an arc structure, and a plurality of ventilation holes are evenly distributed on the ventilation plate.

[0014] By adopting the above technical solution, the heated drying air is evenly sprayed onto the product to be dried through the arc-shaped wind deflector. The uniform dispersion of the drying air reduces the occurrence of the phenomenon that the drying air concentrates at one place and blows the undried ink on the sprayed pattern, thereby improving the drying efficiency and effect of the drying mechanism on the product.

[0015] Preferably, the blowing component includes a first fan and a second fan connected to the heating cover. The first fan is located at the center of the heating cover. The number of the second fans is multiple and the second fans are inclined. The multiple second fans are symmetrically distributed on both sides of the first fan.

[0016] By adopting the above technical solution, the first fan and the inclined second fans provide drying air at multiple angles for the drying mechanism, so that the drying air uniformly contacts the heating wire in an arc structure, thereby improving the uniformity of the drying air and the heating efficiency of the heating wire on the drying air, and further improving the drying efficiency and quality of the drying mechanism on the product.

[0017] Preferably, the conveying assembly includes a support frame, a driving roller, a driven roller, a second driving motor, and a conveyor belt. The driven roller is rotatably connected to the support frame. The second driving motor is fixedly connected to the support frame. One end of the driving roller is fixedly connected to the transmission shaft of the second driving motor, and the other end is rotatably connected to the support frame. The conveyor belt is in transmission connection with both the driving roller and the driven roller.

[0018] By adopting the above technical solution, the second driving motor drives the driving roller to rotate, the driving roller drives the conveyor belt to move, and the conveyor belt conveys the product, thereby completing the drying of the product.

[0019] Preferably, a cooling assembly is provided on the support frame. The cooling assembly includes a cooling fan provided on the support frame.

[0020] By adopting the above technical solution, the cooling fan cools the product after drying is completed, so that the product can be quickly cooled, and thereby the efficiency of packing the product is improved.

[0021] Preferably, heat dissipation holes are formed in the conveyor belt.

[0022] By adopting the above technical solution, the setting of the heat dissipation holes further improves the cooling efficiency of the product, thereby reducing the energy consumption of the cooling fan and improving the packing efficiency of the product.

[0023] Preferably, a first limit plate is fixedly connected to one end of the lead screw away from the first driving motor, and a second limit plate is fixedly connected to one end of the limit rod away from the base.

[0024] By adopting the above technical solution, the first limit plate limits the first connection block, and the second limit plate limits the second connection block, thereby reducing the phenomenon that the first connection block and the second connection block fall off during the movement, and further improving the stability of the height adjustment assembly for adjusting the height of the drying mechanism.

[0025] In summary, the present application has the following beneficial technical effects:

[0026] 1. The height adjustment assembly adjusts the height of the drying mechanism, so that the distance between the drying mechanism and the product is appropriate, thereby improving the drying efficiency and quality of the drying mechanism for the product;

[0027] 2. The arc-shaped heating wire and ventilation plate improve the dispersion uniformity of the drying air and the heating effect of the heating wire on the drying air, thereby improving the drying efficiency and quality of the drying air for the product;

[0028] 3. The setting of the cooling fan and the heat dissipation holes improves the cooling efficiency of the product after drying, thereby improving the packing efficiency of the product. Description of the Drawings
