[0002] As an important printing equipment, gravure printing machine is widely used in packaging, label, wallpaper and other fields. One of its core components is plate roller, which carries printing patterns and is the key to achieve high-quality printing. However, in the daily operation of gravure printing machine, the plate roller loading and unloading process often becomes an important factor restricting efficiency and cost.

[0003] During the loading and unloading process of plate roller, safety and stability need to be ensured to avoid damage or collision. Since plate roller itself is heavy and its surface is coated with precise printing patterns, any minor collision or friction may cause irreversible damage to it. As production scale expands and printing tasks increase, the requirements for plate roller loading and unloading speed and accuracy also become higher. Plate roller loading and unloading usually involves multiple steps, including plate roller positioning, fixing, unlocking, and moving. During disassembly, especially during plate roller movement, handling, positioning adjustment, and plate roller switching, multiple workers are required to work together, which will cause heavy workload on workers. If multiple people do not cooperate properly, operational errors may occur, leading to plate roller damage or printing quality problems. Especially in large printing enterprises, frequent replacement of plate roller to meet the needs of different printing tasks makes this problem more prominent. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions will be further described below in combination with specific embodiments, and it should be noted that: the words such as up, down, left and right in the text only refer to the position of the shown structure in the corresponding drawing. The serial numbers of the components in the text, such as first, second, etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The connection, coupling, etc. mentioned in the application includes direct and indirect connection (coupling) unless otherwise specified.

[0020] A plate roll auxiliary loading and unloading device of a gravure printing machine, as shown in Figures 1-3 The main body 1 is internally integrated with a power module, which is responsible for providing stable power supply for all power components and signal transmission components on the main body 1. On the left lower part of the main body 1, two power wheels 2 are equipped on the front and back sides, and each power wheel 2 is equipped with driving elements that can accurately control the movement of the power wheel 2, thereby ensuring that the entire device can move flexibly within the working area.

[0021] At the same time, the right lower part of the main body 1 is provided with steering wheels 3 on the front and back sides, which work cooperatively with the power wheels 2 to easily realize steering during movement, improving the convenience of operation.

[0022] On the upper part of the main body 1, a mounting seat 4 is stably installed. This mounting seat 4 not only provides solid support for the components above, but also has a lifting platform 41 rotatably installed on its upper part. The rotation of the lifting platform 41 is realized through power elements inside the mounting seat 4, which allows the lifting platform 41 to rotate as needed to adjust the position of the multi-link mechanical arm 42 connected to it.

[0023] The multi-link mechanical arm 42 is composed of at least two connected arm segments, which are connected through hinges or joints to realize flexible movement. One of the arm segments is equipped with a driving device that can accurately control the relative movement between the arm segments, allowing the multi-link mechanical arm 42 to perform various complex actions as needed. In addition, at least one arm segment is equipped with a sensor 91 that can detect the movement position and posture of the arm segment in real time, providing accurate information feedback to the operator.

[0024] As shown in Figure 1 and Figure 2 At the end of the multi-link mechanical arm 42, a supporting arm 43 is provided, which can realize multi-degree-of-freedom movement under the drive of the multi-link mechanical arm 42, making it easy to grasp and place the plate roll body 100 of the gravure printing machine. To further enhance the flexibility of the supporting arm 43, it is connected to the multi-link mechanical arm 42 through a rotary driving element 5, which can drive the supporting arm 43 to rotate around the axis, thereby realizing multi-directional rotation, making the supporting arm 43 more handy when grasping and placing the plate roll.

[0025] In addition, the upper part of the main body 1 is also provided with a sliding rail 61, and the mounting seat 4 is connected with the main body 1 in a sliding manner through the sliding rail 61. This design enables the mounting seat 4 to automatically move on the sliding rail 61 as needed, thereby further expanding the working range of the multi-connected mechanical arm 42 and the supporting arm 43. In order to realize the automatic movement of the mounting seat 4 on the sliding rail 61, the upper part of the main body 1 is also provided with a transmission member 6, which can accurately control the movement of the mounting seat 4 on the sliding rail 61, so that the entire device can more efficiently complete the loading and unloading task of the plate roller.

[0026] Based on the embodiment 1, as shown in Figure 1 、 Figure 3 and Figure 4 , the device is additionally provided with a material system to facilitate the access of the plate roller, and a material placing cavity 7 is formed in the main body 1, and a slidable sliding table 71 is installed at the lower part of the material placing cavity 7. The sliding table 71 is automatically translated forward and backward through a transmission member 2 and a sliding rail 2 81. Specifically, the sliding rail 2 81 is ingeniously arranged at the lower part of the material placing cavity 7, which enables the sliding table 71 to easily slide forward and backward in the material placing cavity 7 of the main body 1. Meanwhile, the transmission member 2 is also arranged in the material placing cavity 7, which is responsible for driving the sliding table 71 to automatically translate forward and backward on the sliding rail. This improvement not only optimizes the access process of the plate roller, but also significantly improves the working efficiency, making the entire system more smooth and efficient. Through the precise cooperation of the transmission member 2 and the sliding rail 2 81, the sliding table 71 can accurately and stably complete the forward and backward sliding action. The support seats 72 are symmetrically arranged on the front and rear sides of the sliding table 71, which are used to stably place the plate roller. In addition, a plate roller can be horizontally placed between the support seats 72 on the same line. Furthermore, the material taking interval 73 is arranged between the support seats 72 on the top of the sliding table 71, which facilitates the entry and exit of the supporting arm 43 to grab the roller body 100, thereby realizing the convenient taking and placing of the plate roller. This design not only improves the convenience of the plate roller access, but also further improves the overall working efficiency.

[0027] In addition, as shown in Figure 3 , the device is also equipped with an advanced control system and sensor network to realize accurate control and real-time monitoring of each component. On one side of the main body 1, a control module 9 is arranged, which is closely connected with the control systems of the power wheels 2, the steering wheels 3, the multi-connected mechanical arm 42 and the supporting arm 43, and is responsible for sending instructions and receiving feedback, thereby ensuring that each component can accurately operate according to the predetermined program.

[0028] At the same time, in order to monitor the running state of the device in real time, sensors 91 are installed on the key parts of the main body 1, the mounting seat 4, the multi-connected mechanical arm 42 and the supporting arm 43, which can accurately capture the key parameters such as the position, speed and force of each component, and feed back the information to the control module 9 in real time, and through processing the feedback information, the control module 9 can adjust the control strategy in time to ensure that the device always maintains the best working state.

[0029] The combination of this control system and sensor network not only improves the automation degree and operation efficiency of the device, but also greatly enhances the stability and reliability of the device.
