Description

Technical Field

[0001] The utility model relates to an ink impurity filtering and removing device, belonging to the technical field of ink printing. Background Art

[0002] The floor film ink printing technology is the most important method for printing the outer pattern of the floor film in the floor film production process. During the printing process, the floor film is respectively wound on the printing roller, the pressure roller and the tensioning roller, and the floor film base film is contacted with the ink groove by the downward pressure of the pressure roller to achieve uniform coloring of the ink. However, some impurities are often mixed into the ink during the contact with the ink, resulting in missing prints on the printed floor film, which affects the appearance of the product. It takes manpower and time to remedy the missing prints by manual repair, which affects the product yield and production efficiency. In addition, in the actual application process, when the printing personnel find impurities, they can only stop the machine to remove them. If they do not stop the machine to remove them, it will cause great safety hazards, which can easily cause personal injury incidents. Therefore, the impurity treatment of the ink is an issue that needs to be solved urgently. Summary of the invention

[0003] Purpose of the invention: In view of the deficiencies in the prior art, the utility model provides an ink impurity filtering and removing device to solve the problems mentioned in the above background technology.

[0004] Technical solution: An ink impurity filtering and removing device, comprising a filtering device arranged outside an ink printing machine and connected to an ink tank, the filtering device comprising a hollow shell, an ink cavity inside the shell, an impurity separation crawler assembly arranged in the ink cavity, and an ink filling port opened at the top of the shell;

[0005] The impurity separation track assembly includes at least two transmission shafts that are laterally arranged and rotatably connected to the outer shell and are installed in an upper and lower dislocation. The transmission shaft is rotatably connected to the outer shell through a bearing. The transmission shaft on the side close to the ink tank is higher than the other transmission shaft. A transmission belt that fits tightly to the transmission shaft is mounted on the transmission shaft. The width of the transmission belt is the same as the width of the ink cavity. A driving motor is connected to any transmission shaft outside the outer shell. A flexible scraper that contacts the surface of the transmission belt is also arranged in the ink cavity. The length of the flexible scraper is the same as the width of the transmission belt. One end of the flexible scraper is fixedly connected to the outer shell.

[0006] In this utility model, a filtering device is separately provided outside the ink printing machine. There is an opening at the position corresponding to the ink tank on the outside of the ink printing machine, and the filtering device is communicated with the ink tank. A conveying track belt is arranged in the filtering device with a high-low staggered arrangement and covers the entire ink chamber. When pouring ink, if impurities are mixed in, or impurities have been incorporated during the storage of the ink, through the separation of the conveying track belt, the impurities in the ink are separated onto the conveyor belt, and the conveyor belt has a mixed liquid of ink and impurities. By the contact between the flexible scraper and the surface of the conveying track belt, the impurities are separated, avoiding direct entry into the ink tank, which may cause the printed matter to be contaminated, resulting in missing printing and affecting the product yield. At the same time, it avoids personal injuries caused by manual cleaning of impurities.

[0007] The conveying track belt is of a screen structure, and the aperture size is 1 mm to 1.5 mm.

[0008] Most of the impurities in the printing process are printing film debris, which are relatively large in volume and have the most serious impact on the product. Therefore, while ensuring that the ink can pass through the conveying track belt, the impurities also need to be filtered out. By controlling the aperture size of the conveying track belt, the separation and liquid leakage can be synchronized, ensuring the supply of ink and cleaning the impurities at the same time.

[0009] The flexible scraper is fixedly connected to the outer shell through a fixed shaft, and the flexible scraper is arranged in the area between the conveying track belt and the ink tank;

[0010] It also includes a fixed frame horizontally arranged and fixedly connected to the lower side of the fixed shaft. The fixed shaft is installed near the middle position of the fixed frame. The length of the fixed frame is the same as the width of the conveying track belt. A net pocket is sleeved outside the fixed frame, and the aperture size of the net pocket is 1 mm to 1.5 mm.

[0011] In order to better collect impurities, by setting the fixed frame and the net pocket structure, after the impurities are scraped off by the flexible scraper, they flow into the net pocket along with the ink for collection. After the machine stops, the net pocket can be taken out and a new net pocket can be replaced to achieve cleaning, which is convenient and fast.

[0012] Positioning studs are arranged at the four corner positions on the upper side of the fixed frame, and the net pocket is detachably arranged on the fixed frame through the positioning studs.

[0013] In order to position the net pocket, by setting a plurality of positioning studs, the net pocket can be sleeved onto the positioning studs to achieve the positioning of the net pocket. The disassembly is simple and the installation is convenient.

[0014] A self-resetting dust cover is arranged near the ink filling port of the ink chamber. The outer diameter of the self-resetting dust cover is larger than the inner diameter of the ink filling port, and the self-resetting dust cover is rotatably arranged at the ink filling port through a spring connector with the inner wall of the outer shell.

[0015] In order to prevent impurities from entering the ink cavity through the ink filling port during filling or operation, a self-resetting dust cover is provided, which can be opened when in use and closed when out of use, thereby greatly reducing the probability of contamination of the ink cavity.

[0016] The ink filling port is arranged at a side away from the ink tank and close to the low-position transmission shaft. A guide plate arranged parallel to the conveying crawler is arranged on the inner wall of the shell between the ink filling port and the high-position transmission shaft.

[0017] In order to avoid the ink not passing through the impurity separation process of the conveyor belt during the filling process, a guide plate is set to make the filled ink flow into the front end of the ink cavity. Light impurities such as paper scraps will float on the surface. Through the action of the conveyor belt, drainage can be achieved, and the surface ink and shallow ink are brought onto the conveyor belt to achieve automatic adsorption of impurities.

[0018] An external threaded tube is provided at the connection between the outer side of the shell and the transmission shaft, and a sealing cap is threadedly connected to the external threaded tube; a sleeve fixed on the shell is provided at the connection between the drive motor and the transmission shaft, a hard graphite sealing ring is provided in the sleeve, and the output end of the drive motor is in close contact with the inner side of the hard graphite sealing ring.

[0019] In order to further strengthen the sealing of the connection between each transmission shaft and the outer casing, a sealing cover is provided at the transmission shaft position that is not connected to the drive motor. When ink seeps out, the sealing is achieved by blocking the sealing cover. The end of the transmission shaft connected to the drive motor is sealed by utilizing the good sealing properties of the hard graphite sealing ring. At the same time, the hard graphite sealing ring also has a good self-lubricating effect, which reduces the friction with the output end of the drive motor.

[0020] Beneficial effects: The utility model separately arranges a filtering device on the outside of the ink printing machine, the outside of the ink printing machine is opened at a position corresponding to the ink tank, the filtering device is connected to the ink tank, and a conveying belt with a high and low offset arrangement is arranged in the filtering device, and covers the entire ink cavity. When pouring ink, if impurities are mixed in it, or the ink has been mixed with impurities during the storage process, the impurities in the ink are separated onto the conveyor belt through the separation of the conveyor belt. The conveyor belt is a mixed liquid of ink and impurities. The impurities are separated by the contact between the flexible scraper and the surface of the conveyor belt, avoiding direct entry into the ink tank to cause contamination of the printed matter, resulting in missed printing, affecting the product yield, and at the same time avoiding personal injury caused by manual cleaning of impurities.
