Description

TECHNICAL FIELD

[0001] The application belongs to the field of printing equipment, and particularly relates to a turnover type precise positioning anilox roller structure. BACKGROUND

[0002] In the printing industry, anilox rollers, as key components for transferring ink, have fine cells engraved on their surfaces for storing and metering ink, which plays a crucial role in printing quality. However, in actual production processes, due to factors such as ink adhesion, wear and aging, anilox rollers need to be replaced or maintained regularly. The traditional replacement method is usually carried out directly at the working position, which not only is complex to operate and time-consuming, but also is easy to cause pollution or damage to other components of the printing machine. In order to simplify the replacement process, some printing machines are designed to allow the anilox roller to be taken out from the working position, and then replaced externally and reinstalled. However, this method encounters new challenges when reinstalling the anilox roller: how to ensure that the anilox roller can be quickly and accurately installed in place to ensure printing quality and efficiency. The traditional installation method often relies on manual adjustment, which is not only time-consuming and labor-intensive, but also difficult to ensure positioning accuracy, which can easily affect the printing effect. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the embodiment of the application is to provide a turnover type precise positioning anilox roller structure to solve the technical problem of low replacement efficiency of the anilox roller in the prior art.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the application is to provide a turnover type precise positioning anilox roller structure, comprising:

[0009] a bearing coaxially sleeved on the connecting section;

[0010] a positioning sleeve connected to the wallboard and used for abutting against the bearing to form an obtuse angle between the opening direction of the open slot and the direction of gravity.

[0011] Optionally, the positioning sleeve is used to form an open accommodating cavity on the side abutting against the bearing, the accommodating cavity is shaped to fit the bearing and is used to accommodate part of the bearing.

[0012] Optionally, the hook arm is formed with an abutting portion shaped to fit the bearing and abutting against the bearing, the abutting portion is arranged on opposite sides of the bearing with the positioning sleeve.

[0013] Optionally, the flip-type precise positioning anilox roller structure further comprises a cylinder and a swing arm.

[0014] The cylinder is mounted on the wallboard, one end of the swing arm is connected to the rotating shaft, and the other end is hinged to the power end of the cylinder and enables the cylinder to drive the rotating shaft.

[0015] Optionally, the flip-type precise positioning anilox roller structure further comprises a coaxially arranged connecting sleeve and an input shaft.

[0016] The connecting sleeve is coaxially connected with the connecting section of one end of the anilox roller, and a clamping groove is formed on the side of the connecting sleeve away from the working section, the clamping groove extends along the radial direction of the connecting sleeve and penetrates through the connecting sleeve.

[0017] The input shaft is rotationally mounted in the positioning sleeve on the side corresponding to the connecting sleeve and is used to connect an external power source, and one end of the input shaft close to the connecting sleeve is formed with a protruding tooth shaped to fit the clamping groove and capable of being inserted into the clamping groove.

[0018] Optionally, the protruding tooth is symmetrically arranged about the central axis of the input shaft.

[0019] Optionally, the flip-type precise positioning anilox roller structure further comprises an ink transfer roller, an ink tray, and an ink inlet pipe and an ink return pipe respectively communicating with the ink tray.

[0020] The ink transfer roller is horizontally arranged on the top of the ink tray and at least partially extends into the ink tray, and the communication port between the ink inlet pipe and the ink tray is closer to the bottom of the ink tray than the communication port between the ink return pipe and the ink tray.

[0021] The flip type precise positioning anilox roller structure provided by the application has the beneficial effects that, compared with the prior art, in the flip type precise positioning anilox roller structure provided by the application, the end of the hook arm away from the rotating shaft is provided with an open slot for supporting the connecting section, and the size of the open slot is greater than the diameter of the connecting section; when the anilox roller needs to be replaced, the old anilox roller can be driven away from the working position by rotating the rotating shaft, so that the new anilox roller can be sent to the working position by reversing the rotating shaft after the new anilox roller is replaced from the opening of the open slot. Since the end of the connecting section is sleeved with a bearing, and since the wallboard is connected with a positioning sleeve capable of abutting against the bearing, and the positioning sleeve can form an obtuse angle between the opening direction of the open slot and the direction of gravity after abutting against the bearing, the replaced anilox roller cannot be separated from the open slot during work, and the positioning sleeve can also be arranged at a predetermined position to quickly and accurately position the anilox roller at the target position, which is beneficial to significantly improve the replacement efficiency of the anilox roller, and is much better than the prior art.
