Description

Technical Field

[0001] This application relates to the technical field of printing equipment, and in particular to a high-utilization, energy-saving lenticular printing equipment. Background Technology

[0002] Lenticular printing is a special printing technology that enables printed materials to present different images or produce a three-dimensional effect when viewed from different angles. Printing can create 3D stereoscopic, image-changing, and moving effects. Lenticular printing is also an existing technology, which mainly includes three techniques: first, offset printing; second, digital printing; and third, flexographic or letterpress printing. However, all three types of printing first use transparent plastic to extrude and form lenticular sheets, and then print them using these three methods.

[0003] The existing publication number CN208101291U, entitled "A High-Precision Lattice Printing Equipment," includes a housing, an inlet, an outlet, a feed roller, an anilox roller, a flexographic cylinder, an impression cylinder, an output roller, an ink cartridge, a first fixed plate, a doctor blade, a first motor, a second motor, and a third motor. The feed inlet is fixedly mounted on the top surface of the housing's outer wall, and the outlet is fixedly mounted on the bottom surface of the housing's outer wall. The feed roller is connected to a rotating shaft at the top of the housing's inner cavity. The first motor is bolted to the top surface of the housing, and an anilox roller is mounted on one side of the bottom of the first motor, connected to the first motor via a chain. This invention effectively re-transfers excess ink to the ink cartridge using a collection box and a delivery pump, preventing ink waste. Temperature and humidity sensors and a fan effectively expel heat and humid air from the housing. An emergency stop button and alarm lights enhance the equipment's safety performance.

[0004] Regarding the aforementioned technologies, the inventors discovered that while the above-mentioned methods utilize structures such as scrapers and collection boxes to recover residual ink, the lack of a drying component after printing results in the ink not drying in time after lenticular printing. This incomplete ink setting leads to the lenticular printing pattern becoming scattered, thus affecting the lenticular printing effect. Utility Model Content

[0005] In order to overcome the problem that the ink in the lenticular printing is not dried in time after the existing drying components are completed, and the ink is not set, resulting in the lenticular printing pattern being easy to be scattered and affecting the lenticular printing effect, this application provides a high-utilization energy-saving lenticular printing equipment.

[0006] The high-utilization, energy-saving lenticular printing equipment provided in this application adopts the following technical solution:

[0007] A high-efficiency, energy-saving lenticular printing device includes a printing press housing. Inside the printing press housing are an anilox roller, a flexographic roller, an impression roller, an ink cartridge, and an ink supply tube. An inlet is located on the upper side of one side of the printing press housing, and a pretreatment component is connected and fixed to the inlet. An outlet is located on the lower side of one side of the printing press housing, and a drying component is connected and fixed to the outlet. The ink cartridge is fixed to the inner wall of the printing press housing, and an ink supply tube is connected and fixed to one side of the ink cartridge, pressing against the anilox roller. The drying component includes a drying frame. A first transparent cover is fixed inside the drying frame near the printing press housing, and multiple infrared lamps are horizontally fixed inside the first transparent cover. A second transparent cover is fixed inside the drying frame away from the printing press housing, and multiple ultraviolet lamps are horizontally fixed inside the second transparent cover.

[0008] By adopting the above technical solution, during printing, the printing substrate is introduced from the feed port of the printing press housing. After the printing substrate is treated by the pretreatment component, the surface flatness of the printing substrate is ensured during printing. Then, ink is delivered to the anilox roller through the ink filling tube using the ink cartridge. The printing substrate is supplied with ink through the anilox tube and then pressed against the flexographic cylinder by the impression cylinder. After the printing substrate is printed, it is discharged from the discharge port of the printing press housing. After the printing substrate is printed, it passes through the drying frame in the drying component. The printing substrate is baked, dried and cured by multiple infrared lamps and multiple ultraviolet lamps set in the first and second transparent covers. This ensures that the ink after lenticular printing dries in time, sets the ink, and ensures the lenticular printing effect.

[0009] Optionally, air boxes are horizontally fixed through the upper and lower sides of the middle of the drying frame, and multiple nozzles are horizontally fixed inside the air boxes.

[0010] By adopting the above technical solution, multiple nozzles on the air box in the middle of the drying frame guide drying air into the drying frame to dry the printed substrate passing through.

[0011] Optionally, an air inlet pipe is connected and fixed to the air box of the drying frame, and a blower is connected and assembled to the air inlet pipe. A heating cylinder is also connected and fixed to the air inlet pipe, and multiple heating resistance wires are fixed inside the heating cylinder.

[0012] By adopting the above technical solution, the air pump on the air inlet pipe of the air box is started to drive the external air into the heating cylinder. The air contacts the multiple heating resistance wires in the heating cylinder, carries the heat generated by the multiple heating resistance wires and delivers it to the air box, and then sprays it onto the printed substrate for drying.

[0013] Optionally, multiple holes are evenly formed on the outer wall of the anilox roller.

[0014] By adopting the above technical solution, the anilox roller uses a laser-engraved cell structure with a cell depth of 20±5μm, an opening angle of 120°±10°, and a cell wall roughness Ra≤0.8μm, which facilitates better guarantee of ink step-by-step uniformity. It is equipped with a Keyence LJ-X series 3D morphology detection module to monitor the cell status in real time and replace the anilox roller in a timely manner.

[0015] Optionally, the impression cylinder includes a pressure cylinder and a high-pressure generator, with the high-pressure generator being horizontally inserted and fixed inside the pressure cylinder.

[0016] By adopting the above technical solution, the impression cylinder is equipped with a high voltage generator of the HCN series, which generates an 800-1200V electrostatic field to adsorb dust on the printing substrate and perform dust removal treatment on the printing substrate.

[0017] Optionally, an ultrasonic viscometer is installed in the ink filling tube of the ink cartridge, and a compensation valve is connected to the ink filling tube.

[0018] By adopting the above technical solution, the ink cartridge can store nano-ink particles with a solid content ≥65% and a particle size D50 ≤200nm. An ultrasonic viscometer and a compensation valve are added to the ink filling tube. The ultrasonic viscometer detects the viscosity of the ink as it passes through, and the compensation valve is connected to ink pipes of different viscosities. Based on the data detected by the ultrasonic viscometer, the addition of inks of different viscosities into the ink filling tube is controlled, maintaining the ink viscosity for 18-22 seconds.

[0019] Optionally, a scraper is horizontally fixed inside the printing press housing, with the other end of the scraper pressing against the outer wall of the anilox roller. A collection box is horizontally fixed inside the printing press housing below the anilox roller, and a recovery pipe is connected to the bottom of the collection box. The other end of the recovery pipe is connected to and fixed to the ink cartridge, and a recovery pump is installed on the recovery pipe.

[0020] By adopting the above technical solution, excess ink on the outer wall of the anilox roller is scraped off by the scraper and falls into the collection box. The recovery pump on the recovery pipe is started to drive the ink to be recovered and stored in the ink box.

[0021] Optionally, the pretreatment component includes a pretreatment frame, which is fixed at the feed inlet of the printing press housing. Multiple guide rollers are horizontally rotatably connected to the lower inner side of the pretreatment frame. A pressure pump is fixed on the top surface of the pretreatment frame, and a paint nozzle is fixedly connected to the discharge end of the pressure pump.

[0022] By adopting the above technical solution, the printing substrate is conveyed into the feed port of the printing machine housing under the guidance of multiple guide rollers in the pretreatment frame. In order to ensure the surface tension of the printing substrate, a corona processor of model Blowon Ion Air Knife and a pressure pump are used to spray primer onto the printing substrate to ensure the adhesion of the printing substrate surface and improve the ink adhesion effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] During printing, the printing substrate is introduced through the feed port of the printing press housing. After pretreatment, the substrate is ensured to have a smooth surface during printing. Ink is then delivered onto the anilox roller via an ink cartridge and ink supply tube. The substrate is then pressed against the flexographic cylinder by the impression cylinder. After printing, the substrate is discharged from the discharge port of the printing press housing. After printing, the substrate passes through the drying frame in the drying unit. The substrate is then baked, dried, and cured by multiple infrared lamps and multiple ultraviolet lamps set in the first and second transparent covers. This ensures that the ink dries in time after lenticular printing, allowing the ink to set and guaranteeing the lenticular printing effect. Attached Figure Description
