[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The present invention relates to a quick roller changing device for facing paper printing equipment, which has the following beneficial effects:

[0016] 1. The driving screw in the limit assembly rotates, and the reverse thread on the outer wall drives the sliding block to move left and right. The stable support rod at the bottom of the sliding block moves accordingly, driving the load-bearing pad to move up and down. When the load-bearing pad contacts the ground and provides support, it can effectively support and limit the stable bracket, ensuring that during the operation of the equipment, the stable bracket will not shake or displace due to external forces or equipment vibrations, etc., providing a stable working foundation for the entire roller changing device and ensuring the accuracy and safety of the roller changing operation.

[0017] 2. The stable bracket supports the driven gear disc, ensuring the stability of the driven gear disc in the related transmission process such as driving the linkage rotating rod to rotate, making the power transmission of the entire device more reliable, and helping to improve the operating accuracy and stability of the equipment. The universal wheel set at the bottom of the stable bracket allows the entire device to be flexibly moved. When the equipment needs to be repositioned or transferred between different work areas, the operator can easily push the device without the help of complex handling equipment, which greatly improves the ease of use and site adaptability of the equipment, saves manpower and time costs, and facilitates the rapid deployment and use of the roller changing device in different work scenarios.

[0018] 3. The driving sprocket in the drive assembly is engaged with the driven sprocket, and the driving handle drives the driving sprocket to rotate, thereby driving the driven sprocket to rotate. This gear transmission method has the advantages of high transmission efficiency and accurate transmission ratio. It can effectively transmit the driving force to the driven sprocket, ensuring that the power of the roller rotation is sufficient and stable, providing reliable power support for the normal operation of the facing paper printing equipment. The design of the driving handle facilitates manual operation by the operator, making the rotation control of the driving sprocket more direct and convenient. The operator can flexibly adjust the speed and direction of the driving sprocket according to actual needs to meet different work requirements.

[0019] 4. The limit slide set on the outer wall of the driving handle can limit the driving gear disc through the cooperation of the limit rod on one side and the limit hole opened on the driving gear disc. When the position of the driving gear disc needs to be fixed, the limit slide, under the action of the spring, inserts the limit rod of the limit slide into the limit hole of the driving gear disc to prevent the driving gear disc from rotating accidentally, thereby ensuring the stability of the equipment during operation and the accuracy of the working state. This limit design allows the operator to accurately control the rotation angle and position of the driving gear disc, thereby achieving precise control of the rotation of the roller, providing reliable protection for the different process requirements in the printing process of facing paper, such as the adjustment of printing speed, roller pressure, etc., thereby improving printing quality and production efficiency.

[0020] 5. The rotating screw inside the stable vertical plate drives the strong splint to move up and down through the outer wall thread. The arc-shaped groove set on the inner wall of the strong splint is used to clamp the roller. This design can be flexibly adjusted according to the different sizes and shapes of the roller. By adjusting the rotating screw, the roller can be tightly clamped to ensure that the roller will not loosen or fall off during the roller changing process, thereby improving the safety and reliability of the roller changing operation. The design of the arc-shaped groove increases the contact area with the roller surface, making the clamping more stable, while also reducing the damage to the roller surface, protecting the quality and service life of the roller, which is of great significance for ensuring the printing quality of facing paper.
