[0037] Reference Figure 1 and Figure 3A fixing frame 56 is fixedly connected to the left end of the top of the workbench 1. The fixing effect of the fixing frame 56 prevents the fixing frame 56 from falling off. An electric push rod 58 is fixedly connected to the right end of the top of the fixing frame 56. The electric push rod 58 is a prior art. The fixing effect of the electric push rod 58 prevents the electric push rod 58 from falling off. A telescopic rod 55 is fixedly connected to the back of the inner wall of the workbench 1. The telescopic rod 55 is symmetrically distributed in two groups. The telescopic rod 55 guides the guide rod 51 to prevent the guide rod 51 from deviating during movement.

[0038] Reference Figure 1 and Figure 2 The right end of the back side of the guide rod 51 is fixedly connected to the front end of the telescopic rod 55, and the outer wall of the slider 53 is slidably connected to the inner wall of the slide groove 57. The sliding effect of the slider 53 drives the hinged rod 52 to move, and the right side of the connecting frame 54 is fixedly connected to the output end of the electric push rod 58. By starting the electric push rod 58, the connecting frame 54 is driven to move horizontally.

[0039] Reference Figure 5 and Figure 6 The front side of the clamping sleeve 61 is fixedly connected to the output shaft of the motor 3. By starting the motor 3, the clamping sleeve 61 is driven to rotate. The outer wall of the fixed block 64 is clamped with the inner wall of the clamping groove 65. The clamping effect of the fixed block 64 and the clamping groove 65 limits the rotation shaft 62, so that the clamping sleeve 61 can drive the rotation shaft 62 to rotate. The inner wall of the right rear end of the sleeve 63 is elastically connected with a wedge block 67 through a spring 68. Through the elastic force of the spring 68, the wedge block 67 always maintains the clamping effect with the square groove under the action of external force, and limits the sleeve 63. A circular ring 66 is fixedly connected to the right end of the back side of the workbench 1. The fixing effect of the circular ring 66 prevents the circular ring 66 from falling off. The outer wall of the circular ring 66 is provided with a square groove. The outer wall of the rotating shaft 62 is fixedly connected to the inner wall of the printing roller 4. The printing roller 4 is driven to rotate through the rotation effect of the rotating shaft 62.

[0040] Reference Figure 3 and Figure 6 The outer periphery of the sleeve 63 penetrates and is slidably connected to the inner wall of the right end of the back side of the workbench 1. Through the sliding effect of the sleeve 63, the sleeve 63 and the rear end of the rotating shaft 62 are plugged in or unplugged, and the outer periphery of the sleeve 63 is slidably connected to the inner wall of the ring 66.

[0041] Reference Figure 5One end of the spring 68 is fixedly connected to the inner wall of the right rear end of the sleeve 63, and the other end of the spring 68 is fixedly connected to the outer wall of the wedge block 67. The fixing effect of the spring 68 keeps the wedge block 67 fixed to prevent the wedge block 67 from falling off. The outer wall of the wedge block 67 is slidably connected to the inner wall of the right rear end of the sleeve 63. The sliding effect of the wedge block 67 allows the wedge block 67 to be engaged or released from the square groove. The outer wall of the wedge block 67 is engaged with the inner wall of the square groove. The engagement effect of the wedge block 67 and the square groove allows the ring 66 to limit the sleeve 63.

[0042] Working principle: When the carton needs to be printed, the staff will place the carton on the electric conveyor belt 2, start the electric conveyor belt 2 and the motor 3, and convey the carton through the electric conveyor belt 2. At the same time, the two sets of guide rods 51 guide the carton to prevent the carton from shifting during movement. When the carton moves to the bottom of the printing roller 4, the motor 3 drives the clamping sleeve 61 to rotate, so that the rotating shaft 62 drives the printing roller 4 to rotate, thereby printing the carton.

[0043] When it is necessary to print cartons of different sizes, the staff starts the electric push rod 58, which drives the connecting frame 54 to move horizontally, so that the slider 53 slides along the inner wall of the slide groove 57, so that the hinge rod 52 drives the guide rod 51 to move, so that the two groups of guide rods 51 move away from or close to each other to adapt to cartons of different sizes.

[0044] When it is necessary to replace the printing roller 4 to adjust the printing shape, the staff presses the wedge block 67 so that the wedge block 67 releases the clamping effect with the square groove and releases the limiting effect on the sleeve 63. The sleeve 63 is slid away from the workbench 1 by using the handle, so that the sleeve 63 is released from the plug-in effect of the rotating shaft 62. The staff moves the rotating shaft 62 toward the back of the workbench 1 so that the rotating shaft 62 is released from the plug-in effect with the clamping sleeve 61, so that the rotating shaft 62 and the printing roller 4 are removed. The front end of the rotating shaft 62 set on the replaced printing roller 4 is plugged into the clamping sleeve 61, and the fixing block 64 is clamped into the clamping groove 65, and the sleeve 63 is slid in the direction close to the workbench 1 until it is plugged into the rear end of the rotating shaft 62, so that the wedge block 67 is clamped with the square groove under the elastic force of the spring 68, and the sleeve 63 is limited so that the sleeve 63 remains fixed, thereby completing the installation and replacement of the printing roller 4.
