Description
Technical Field
[0001] This utility model relates to the field of planar printing technology, and in particular to a contactless planar printing device. Background Technology
[0002] In the wood processing industry, printing decoration on wood surfaces is a crucial step in enhancing product added value and meeting diverse market demands. However, current traditional printing methods face numerous insurmountable problems when applied to wood printing. Wood, as a natural material, exhibits significant differences in characteristics between different species. In terms of hardness, pine is relatively soft, with a density typically between 0.39 and 0.49 g / cm³, while beech is hard, with a density reaching 0.7 to 0.8 g / cm³. Regarding grain, oak possesses a unique mountain-shaped grain, characterized by its coarse and clear texture; while cherry wood has a finer, straighter, and more uniform grain. These differences in wood characteristics typically necessitate the use of printers employing different printing methods.
[0003] Currently, traditional printers are all contact printers, such as screen printing and heat transfer printing. This presents the following problems in actual operation:
[0004] 1. Traditional contact printing requires the inkjet module to come into contact with the wood. This means that the wood needs to be treated before printing. For wood with low hardness, surface hardening treatment is required, such as applying hardener or chemical impregnation. For wood with very complex or rough texture, sanding and polishing are required to obtain a smooth printing surface. Otherwise, the protruding parts of the printer during the printing process may damage the inkjet module, causing the inkjet module to be damaged.
[0005] 2. During the wood printing process, staff need to move the wood boards onto the printing platform. Some high-density woods are quite heavy, and the printing platform of the printer is a certain distance from the ground, so staff need to spend a lot of effort to move them up. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide a non-contact planar printing device to solve the technical problem that when printing wood with current printers, the wood needs to undergo a lot of pre-treatment, such as sanding the wood surface flat, otherwise the protruding bumps on the wood surface will touch the print head and collide, causing damage to the inkjet module of the printer. In addition, due to the large volume and weight of the wood, it requires multiple people to move the wood onto the printer printing platform.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] A contactless planar printing device includes a printer, wherein a contactless printing mechanism is fixedly mounted on the outer surface of the printer, and an auxiliary handling mechanism is fixedly mounted on the top of the printer.
[0010] The contactless printing mechanism includes a moving component, which includes a moving frame. A moving box is slidably mounted on the outer surface of the moving frame. A moving motor is fixedly mounted on the inner wall of the moving box. A moving shaft is fixedly mounted on the output end of the moving motor via a reducer. A moving wheel is fixedly mounted on the outer surface of the moving shaft.
[0011] As an improved technical solution, the two opposing sides of the movable frames are fixedly connected to the outer surface of the printer, and the outer surface of the movable wheels is connected to the inner surface of the movable frames in a transmission connection.
[0012] As an improved technical solution, the contactless printing mechanism further includes a lifting assembly, which includes a lifting motor. The bottom of the lifting motor is fixedly connected to the inner cavity of the moving frame. The output end of the lifting motor is fixedly installed with a No. 1 threaded shaft through a reducer. A lifting rod is threaded on the outer surface of the No. 1 threaded shaft, and a printing platform is fixedly installed on the top of the lifting rod.
[0013] As an improved technical solution, the contactless printing mechanism further includes a printing component, which includes a parallel motor. The outer surface of the parallel motor is fixedly connected to the inner surface of the printing platform. The output end of the parallel motor is fixedly mounted with a second threaded shaft via a reducer. A movable plate is threaded onto the outer surface of the second threaded shaft.
[0014] As an improved technical solution, the bottom of the movable plate penetrates through the printing platform and extends to the outside of the printing platform. A printer is fixedly installed at the bottom of the movable plate, a distance sensor is fixedly installed at the bottom of the printer, an inkjet module is arranged at the bottom of the printer and away from the distance sensor, and a spray tube is connected to the back of the printer.
[0015] As an improved technical solution, the auxiliary handling mechanism includes a first rotating motor, the outer surface of which is fixedly connected to the inner cavity of the printer via a fixing frame, the output end of which is fixedly mounted with a first rotating shaft via a reducer, and the outer surface of which is fixedly mounted with a first support arm.
[0016] As an improved technical solution, the auxiliary handling mechanism further includes a second rotating motor. The outer surface of the second rotating motor is fixedly connected to the outer surface of the first support arm through a fixing frame. A second rotating shaft is fixedly installed on the outer surface of the second rotating motor through a reducer. A second support arm is fixedly installed on the outer surface of the second rotating shaft.
[0017] As an improved technical solution, the auxiliary handling mechanism further includes a rotating block, the inner surface of which is rotatably connected to the outer surface of the second support arm, a placement platform is fixedly installed on the top of the rotating block, and the auxiliary handling mechanism further includes an auxiliary wheel, the outer surface of which is rotatably connected to the inner surface of the printer.
[0018] After adopting the above technical solution, the beneficial effects of this utility model are:
[0019] 1. This utility model incorporates a non-contact printing design for flatbed printers. Through the coordinated use of a moving motor and moving shaft with moving wheels and a moving frame, a lifting motor and a first threaded shaft with a lifting rod and a printing platform, a parallel motor and a second threaded shaft with a moving plate and a printer, and a distance sensor and inkjet module with a printing nozzle, the inkjet module is positioned higher than the wooden board. This eliminates the need for fine sanding of the board before printing. The printer automatically adjusts the height of the inkjet module according to the surface height of the wooden board, preventing damage to the inkjet module caused by protruding parts during printing.
[0020] 2. This utility model adds a design that assists the printer in moving the wooden board. Through the cooperation of a first rotating motor and a first rotating shaft with a first support arm and a second rotating motor, the cooperation of a second rotating motor and a second rotating shaft with a second support arm and a rotating block, and the cooperation of the rotating block and the placement platform with the auxiliary wheels and the printer, the wooden board can be moved to the top of the printer, reducing the force required to move the wooden board to the top of the printer and improving the efficiency of wooden board moving.
