Description

Technical Field

[0001] The utility model relates to the technical field of printing and drying, in particular to a drying device for printing of printed matter. Background Technique

[0002] Printing is a technology that transfers the original manuscripts such as characters, pictures, photos, anti-counterfeiting, etc. to the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, ink application, and pressing, and batch-replicates the content of the original manuscripts. After the printed matter is dried, it is necessary to dry the ink on the printed matter.

[0003] When the existing drying device dries the printed matter, it usually blows hot air directly at the printed matter. Blowing hot air directly at the printed matter will blow away the un-dried ink on the printed matter, thereby producing defective printed matter and reducing the yield of the printed matter. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drying device for printing of printed matter, which has the advantage of evenly drying the printed matter and solves the problem of ink deviation of the printed matter caused by blowing hot air directly at the printed matter.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drying device for printing of printed matter, including a bracket, a conveying device is installed at the top end of the bracket, the conveying device includes a frame, a blowing device is installed in the middle of one side of the frame, and a drying chamber is installed in the middle of the top end of the frame. The drying chamber includes a housing, two partitions are symmetrically installed at the bottom end inside the housing, and a diversion mechanism is installed at the top end inside. The diversion mechanism includes a hot air chamber. Through holes are opened at the bottom ends of both sides of the hot air chamber parallel to the partitions, and two heating plates are symmetrically installed in the hot air chamber.

[0006] Preferably, a through groove communicating with the blowing device is opened at the top end of the hot air chamber. The three through holes are all strip-shaped and are evenly distributed at the bottom end of the hot air chamber. The two heating plates are arc-shaped and form a semi-circular shape, and ventilation grooves are arranged at the top ends of the two heating plates and are located below the through groove.

[0007] Preferably, a cavity is opened inside the frame, a conveying mechanism is installed inside the cavity, and a servo motor for driving the conveying mechanism to rotate is installed at the bottom end of the frame.

[0008] Preferably, the conveying mechanism includes a long rod, chains are connected to both ends of the long rod, the two chains are tensioned by two gears, and the two chains are synchronously driven by a linkage shaft fixed on the gears.

[0009] Preferably, the blowing device includes a support rod attached to the side of the frame. A blower is installed at the top of the support rod, and an air duct is connected to the blower. The air duct extends into the housing and is connected to the through groove.

[0010] Preferably, both sides of the hot air chamber in the same direction as the traveling direction of the conveying device are closed. After the hot air in the hot air chamber enters the through groove, it is split into three streams by two heating plates.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing a hot air chamber, a through groove, through holes, and heating plates, the present utility model guides the air generated by the blower into the hot air chamber through the through groove. While splitting the air by two arc-shaped heating plates, it can also improve the heating efficiency of cold air. The hot air is discharged through multiple through holes and between the two heating plates to dry the printed matter. By setting multiple air ducts, the wind speed can be reduced, the residence time of the air in the hot air chamber can be increased, and the temperature of the air for drying the printed matter can be increased, achieving the effect of uniformly drying the printed matter.

[0013] 2. By providing a servo motor, a long rod, a chain, gears, and a linkage shaft, when the servo motor works, it drives the gear to rotate. Through the linkage shaft, multiple gears rotate synchronously. The long rod between the chains is driven to move by the gears meshing with the chain, thereby completing the conveyance of the printed matter. The hollow bottom method can avoid the phenomenon that the bottom of the printed matter is not completely dried. BRIEF DESCRIPTION OF THE DRAWINGS
