Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, specifically an energy-saving and environmentally friendly printing device. Background Technology

[0002] Printing equipment is a device that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC, to reproduce the content of the original manuscript in batches. Printing machines are classified according to the form of the printing plate into letterpress, planographic, gravure, and screen printing machines; and according to the plate mounting and pressing structure into flatbed, rotary-flatbed, and rotary-rotary printing machines.

[0003] The specific design and structure of energy-saving and environmentally friendly printing equipment may vary depending on different manufacturers and application requirements, but generally they include the following key parts: base, drying mechanism, etc. The base usually serves to support the entire equipment and is generally made of sturdy materials to ensure the stability of the equipment during operation; the drying mechanism is an important part of the equipment, and the drying mechanism usually includes heating elements, fans, air ducts and other components. The heating elements can be electric heating wires, infrared heaters, etc., which dry the printed materials by heating the air.

[0004] Existing energy-saving and environmentally friendly printing equipment has certain drawbacks. When drying ink on printing materials, the ink evaporates and diffuses into the air with the heat, emitting odors and seriously polluting the environment. The waste heat generated by the drying mechanism also diffuses directly into the air, failing to be fully utilized and causing resource waste. When dealing with printing materials that are much thicker than the design standard, the printing roller may not be able to make sufficient contact with the material, resulting in uneven ink transfer and serious quality problems such as blurry or missing colors in the printed pattern. To address these issues, an energy-saving and environmentally friendly printing device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes an energy-saving and environmentally friendly printing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an energy-saving and environmentally friendly printing device, including a base, a first mounting seat is provided on the base, a release roller is rotatably mounted on the first mounting seat, a first motor bracket is provided on the side of the first mounting seat, a release motor is mounted on the first motor bracket, and the output end of the release motor is fixedly connected to the rotation shaft of the release roller.

[0007] A printing box is provided on the side of the first mounting base. A printing roller is provided inside the printing box. A printing mold is provided on the printing roller. A second motor bracket is provided on the side of the printing box. A printing motor is installed on the second motor bracket. The output end of the printing motor is fixedly connected to the rotating shaft of the printing roller. A first driven roller is provided below the printing roller. A first lead screw is provided on the first driven roller. Positioning nuts are rotatably installed at both ends of the first lead screw. A first sliding groove is opened on both sides of the printing box, and the positioning nuts are located on the outside of the two first sliding grooves.

[0008] Preferably, a second mounting base is provided on the side of the printing box, and an auxiliary roller is rotatably mounted on the second mounting base. A third motor bracket is provided on the side of the second mounting base, and an auxiliary motor is mounted on the third motor bracket. The output end of the auxiliary motor is fixedly connected to the auxiliary roller. A second driven roller is provided below the auxiliary roller, and a second lead screw is provided on the second driven roller. Fixing nuts are rotatably mounted at both ends of the second lead screw. A second sliding groove is provided on the second mounting base, and the fixing nuts are respectively located on the outer sides of the two second sliding grooves. In this way, the gap between the auxiliary roller and the second driven roller can be adjusted according to the actual thickness of the printing material. If thicker materials are to be printed, the gap can be increased; if thin materials are to be printed, the gap can be decreased, ensuring effective conveying and good contact pressure for materials of different thicknesses, thereby improving printing quality.

[0009] Preferably, the base has an installation slot, a drying pipe is installed in the installation slot, a drying box is installed above the installation slot, a circulating motor is installed in the drying box, an air box is installed below the circulating motor, a circulating fan is installed in the air box, and the output end of the circulating motor is fixedly connected to the circulating fan. Through the design of the air inlet at the bottom of the air box, the air supply pipe, the circulating box, and the duct, the air forms an orderly circulation path in the drying box. The circulating fan can effectively drive the air to flow along this path, allowing the hot air to come into full contact with all parts of the printed matter, further improving the drying efficiency.

[0010] Preferably, the top of the drying box is equipped with a circulation box, and the circulation box is equipped with an activated carbon plate. The bottom of the air box has an air inlet. The two sides of the air box are connected to the circulation box through air supply pipes. The two ends of the circulation box are equipped with conduits, and the other end of the conduits passes through the drying box and is located inside the drying box. During the drying process, the organic waste gas generated by the volatilization of ink and other substances on the printed materials is carried into the air box by the circulating fan. This waste gas enters the circulation box through the air supply pipes. After being adsorbed by the activated carbon plate, the harmful components such as volatile organic compounds can be effectively removed. This helps to reduce the pollution of workshop air quality during the printing process, protect the health of operators, and also meets environmental protection requirements.

[0011] Preferably, a No. 3 mounting base is provided on the side of the drying chamber, and a take-up roller is rotatably mounted on the No. 3 mounting base. A No. 4 motor bracket is provided on the outside of the No. 3 mounting base, and a take-up motor is mounted on the No. 4 motor bracket. The output end of the take-up motor is fixedly connected to the take-up roller. The take-up motor is connected to the take-up roller, and the automatic rotation of the take-up roller is achieved by the motor drive. After the printed matter is dried, the take-up roller can automatically rewind the printed matter, which greatly improves work efficiency compared to manual winding.

[0012] Preferably, both ends of the printing box and the drying box are provided with slots for the printing material to enter and exit; the slots at both ends of the printing box and the drying box allow the printing material to smoothly enter the drying box from the printing box, forming a continuous production process. This continuous material transfer path avoids the printing material from stopping or repositioning during the transfer process, ensuring a close connection between the printing and drying stages.

[0013] The advantages of this invention are: the organic waste gas generated by the volatilization of ink and other substances on printed materials is carried into the air box by the circulating fan. This waste gas enters the circulation box through the air supply pipe. After being purified by the activated carbon plate, the air returns to the drying box through the duct, realizing the recycling of air. This not only reduces the amount of fresh air introduced and the energy consumption required to heat a large amount of fresh air, but also avoids the direct emission of waste gas, making it more environmentally friendly.

[0014] The design of the No. 2 lead screw and the fixing nut allows for flexible adjustment of the position of the No. 2 driven roller. By rotating the fixing nut, the No. 2 driven roller can move up and down along the No. 2 lead screw under the constraint of the No. 2 slide. This allows for adjustment of the gap between the auxiliary roller and the No. 2 driven roller according to the actual thickness of the printing material. For thicker materials, the gap can be increased; for thinner materials, the gap can be decreased, ensuring effective conveying and good contact pressure for materials of different thicknesses, thereby improving printing quality.
