Description

Technical Field

[0001] This utility model relates to the field of green printing technology, specifically a green printing device equipped with a waste gas filtration and purification structure. Background Technology

[0002] Green printing refers to a printing method that follows environmental protection principles throughout the entire printing lifecycle, including raw material procurement, production and processing, use, and recycling, adopting environmentally friendly materials and processes to reduce resource consumption and environmental pollution, while ensuring the safety of printed materials and human health. The core objective is to achieve sustainable development of the printing industry, reduce resource consumption during the printing process, such as using lightweight paper, reducing ink usage, optimizing layout to reduce waste, eliminating or reducing the use and emission of toxic and harmful substances, prioritizing environmentally friendly raw and auxiliary materials, reducing health hazards to operators and consumers, promoting the recycling of printing waste, and improving resource recycling rates.

[0003] Green printing involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper, textiles, plastics, and leather through processes such as plate making, inking, and pressure application. Therefore, the invention and development of green printing equipment plays an important role in the dissemination of human civilization and culture. However, existing green printing equipment often generates and emits a lot of waste gas during printing. Negative pressure devices are usually used to extract the waste gas, but after extraction, the waste gas needs to be filtered for purification. Impurities and particles easily accumulate on the filter screen, and the blockage of impurities reduces the speed of waste gas discharge. Utility Model Content

[0004] The purpose of this utility model is to provide a green printing device with a waste gas filtration and purification structure to solve the problem mentioned in the background art that existing green printing devices often generate and emit a lot of waste gas during printing. Usually, a negative pressure device is used to extract the waste gas, but after extraction, the waste gas needs to be filtered for purification. Impurities and particles are easily accumulated on the surface of the filter screen, and the blockage of impurities reduces the speed of waste gas discharge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a green printing device with a waste gas filtration and purification structure, comprising a supporting shell, a drive motor fixedly connected to its rear surface, a transmission roller installed on the inner wall of the cavity of the supporting shell, a conveyor belt provided on the outer surface of the transmission roller, a waste treatment box fixedly connected to the upper surface of the supporting shell, a suction pipe installed through the upper surface of the supporting shell, a mounting bracket fixedly connected to the lower surface of the suction pipe, a waste gas suction nozzle fixedly connected to the inner surface of the mounting bracket, an exhaust pipe fixedly connected to the side surface of the waste treatment box, and a linkage anti-clogging mechanism provided on the surface of the supporting shell.

[0006] Preferably, the supporting shell and the transmission roller are rotatably connected, the shaft of the transmission roller on one side is fixedly connected to the output end of the drive motor, and the waste treatment box is connected to the suction pipe.

[0007] The above technical solution, with its rotating connection design between the outer shell and the transmission roller, provides a stable installation foundation and flexible rotation space for the transmission roller. Combined with the structure of "one side of the transmission roller shaft being fixedly connected to the output end of the drive motor", the power of the drive motor can be directly and losslessly transmitted to the transmission roller, ensuring the smooth operation of the conveyor belt, guaranteeing the continuity and accuracy of the printing process, and avoiding problems such as printing misalignment and material conveying jams caused by poor power transmission.

[0008] Preferably, the mounting bracket has an inverted concave design, the exhaust gas nozzles are distributed in a matrix, and the exhaust gas nozzles are connected to the suction pipe.

[0009] Using the above technical solution, the mounting bracket adopts an inverted concave design, which can adapt to the conveyor belt's transport path and form a semi-enclosed coverage of the printing material from the top, bottom, or sides. Combined with the matrix-distributed exhaust gas nozzles, it can achieve all-round, no-dead-angle capture of exhaust gas in the printing area. Compared with single-point or decentralized nozzles, it greatly improves the uniformity and integrity of exhaust gas collection and avoids excessively high local exhaust gas concentrations and diffusion escape.

[0010] Preferably, a purification filter screen is installed on the inner wall of the waste treatment box, and a first helical gear is rotatably installed on the front surface of the supporting shell, and the shaft of the first helical gear is fixedly connected to the shaft of a transmission roller on one side.

[0011] Using the above technical solution, the purification filter installed on the inner wall of the waste treatment box is a key component for waste gas purification. It can effectively intercept impurities such as ink particles and volatile organic compounds in the waste gas, achieve preliminary filtration and purification of the waste gas, ensure that the gas emitted into the atmosphere meets environmental protection standards, reduce air pollution, and conform to the environmental protection concept of green printing.

[0012] Preferably, the linkage anti-blocking mechanism includes a second helical gear, which is mounted on the front surface of the support housing. A squeezing cam is fixedly connected to the upper end of the shaft of the second helical gear. A linkage slide plate is provided on the front surface of the waste disposal box. A support rod is fixed to the surface of the linkage slide plate, and a cleaning scraper is fixed to one end of the support rod.

[0013] Using the above technical solution, the cleaning scraper is fixed to the linkage slide plate through the support rod, which can accurately fit the surface of the purification filter and ensure that the cleaning action is directly applied to the area where impurities accumulate. Compared with traditional anti-clogging methods such as airflow backflushing, the cleaning effect is more thorough and can effectively remove stubborn particulate impurities attached to the filter surface, maintaining the air permeability of the filter and the efficiency of exhaust gas purification.

[0014] Preferably, the second helical gear is rotatably connected to the supporting housing, and the second helical gear is meshed with the first helical gear, and the extrusion cam is in contact with the surface of the linkage slide plate.

[0015] By adopting the above technical solution, the second helical gear is rotatably connected to the support housing, while simultaneously meshing with the first helical gear. Utilizing the strong stability and high load-bearing capacity of the helical gear meshing transmission, the rotational power of the transmission roller is accurately transmitted to the extrusion cam, avoiding slippage and deviation during power transmission, and ensuring the stability and continuity of the linkage anti-blocking mechanism.

[0016] Preferably, the linkage slide plate and the waste disposal box are slidably connected, and a spring is connected between the linkage slide plate and the waste disposal box, and the support link is slidably connected to the waste disposal box.

[0017] By adopting the above technical solution, the sliding connection between the linkage slide plate and the waste disposal box is combined with the spring connection design. Under the combined action of the periodic extrusion of the extrusion cam and the elastic reset of the spring, the linkage slide plate can automatically reciprocate. There is no need to set up an additional reset mechanism, which simplifies the equipment structure. Moreover, the frequency of the reciprocating motion is synchronized with the speed of the transmission roller, ensuring that the cleaning scraper can continuously and evenly clean the purification filter screen, avoiding blockage in some areas of the filter screen due to untimely cleaning.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this green printing device equipped with a waste gas filtration and purification structure: 1. Through the matrix-distributed exhaust gas nozzles and the connection design of the suction pipes and waste treatment box, the printing exhaust gas can be captured and transported in all directions. Combined with the interception and filtration of the purification filter, impurities and harmful particles in the exhaust gas are effectively removed, ensuring that the emitted gas meets environmental protection standards, reducing the harm to the environment and human health, and conforming to the core concept of green printing. 2. Relying on the power linkage between the transmission roller and the helical gear, the cleaning scraper is driven to clean the purification filter screen back and forth, solving the problem of filter screen clogging from the root. There is no need for frequent manual disassembly and maintenance, which not only ensures the stability of the waste gas treatment efficiency, but also reduces the time and labor costs of equipment operation and maintenance, and improves the overall continuity of operation. 3. The components are connected by rotation and sliding to achieve precise power transmission, eliminating the need for additional drive equipment. This saves energy and simplifies the equipment structure. The inverted concave mounting bracket and spring reset design ensure that the functions of exhaust gas collection, power transmission, and anti-clogging cleaning work together, greatly improving the operational stability and service life of the equipment.

The mounting bracket 7 has an inverted concave design. The waste gas nozzles 8 are distributed in a matrix and are connected to the suction pipe 6. When the drive motor 2 is started, its output end drives the transmission roller 3 fixedly connected to it to rotate inside the supporting shell 1. The transmission roller 3 drives the conveyor belt 4 to rotate through friction, realizing the smooth transportation of printing materials and providing a stable material transport foundation for subsequent printing processes.

[0023] A transmission roller 3 is installed on the inner wall of the cavity of the supporting shell 1. A conveyor belt 4 is provided on the outer surface of the transmission roller 3.

A first helical gear 11 is rotatably installed on the front surface of the supporting shell 1. The shaft of the first helical gear 11 is fixedly connected to the shaft of the transmission roller 3 on one side. The exhaust gas generated during the printing process is extracted through the exhaust gas nozzles 8 distributed in a matrix on the mounting bracket 7. The exhaust gas is directionally transmitted to the waste treatment box 5 above the supporting shell 1 through the suction pipe 6 connected to the nozzles, thus completing the collection and transportation of exhaust gas from the source to the purification unit.

[0024] The linkage anti-blocking mechanism includes a second helical gear 12, which is mounted on the front surface of the support housing 1. A squeezing cam 13 is fixedly connected to the upper end of the shaft of the second helical gear 12. A linkage slide plate 14 is provided on the front surface of the waste disposal box 5. A support rod 15 is fixed to the surface of the linkage slide plate 14. A cleaning scraper 16 is fixed to one end of the support rod 15.

The first helical gear 11, which is fixedly connected to the shaft of the transmission roller 3, rotates synchronously with the transmission roller. Through meshing, it drives the second helical gear 12 to rotate on the front surface of the support housing 1. The squeezing cam 13 at the upper end of the shaft of the second helical gear 12 rotates accordingly, periodically squeezing the linkage slide plate 14 on the front surface of the waste disposal box 5.

[0025] The second helical gear 12 is rotatably connected to the supporting housing 1, and the second helical gear 12 is meshed with the first helical gear 11.

The purified exhaust gas is discharged through the exhaust pipe 9, realizing the simultaneous completion of exhaust gas purification and anti-clogging.

[0026] Working principle: When using this green printing device equipped with a waste gas filtration and purification structure, the drive motor 2 drives the transmission roller 3 to rotate inside the support housing 1, driving the conveyor belt 4 to transport printing materials. The waste gas generated during printing is extracted through the matrix-type waste gas suction nozzle 8 on the mounting bracket 7 and enters the waste treatment box 5 through the suction pipe 6. At the same time, the transmission roller 3 drives the first helical gear 11 to rotate, meshing and driving the second helical gear 12 and the upper extrusion cam 13 to rotate, periodically extruding the linkage slide plate 14. The linkage slide plate 14 slides back and forth under the action of spring reset, driving the cleaning scraper 16 to scrape the purification filter screen 10 through the support connecting rod 15, avoiding filter screen blockage. Finally, the waste gas purified by the filter screen is discharged from the exhaust pipe 9. The whole process relies on the linkage of components to realize the simultaneous operation of material transmission, waste gas collection, purification and anti-blocking. No additional drive is required, which is highly efficient, environmentally friendly and stable in operation, increasing the overall practicality.
