[0016] The first embodiment of the present application is:
[0017] See also Figure 1 , Figure 1 It is a structural schematic diagram of the utility model, including a body 101, a printing roller 102 and an adjustment component, the adjustment component includes a mounting block 103, an adjustment frame 104, a driving member and a buffer member; the driving member includes a servo motor 105, a screw 106 and a sleeve 107, and the buffer member includes a first damping rod 108 and a spring 109. The above scheme solves the problem that the servo motor of the plate roller adjustment mechanism of the existing printing press has a poor buffering effect, and the pressure of the adjustment mechanism acts on the servo motor, damaging the internal components of the servo motor. It can be understood that the above scheme can be used in the scenario of adjusting printing equipment.
[0018] According to the present specific embodiment, the printing roller 102 is arranged on one side of the machine body 101, the adjusting component is arranged on one side of the printing roller 102 and the machine body 101, the mounting block 103 is arranged between the machine body 101 and the printing roller 102, the adjusting frame 104 is fixedly connected to the mounting block 103, and is located on the side of the mounting block 103 away from the printing roller 102, the driving member is arranged at the bottom of the adjusting frame 104, the buffer is fixedly connected to the adjusting frame 104, and is located on the side of the adjusting frame 104 close to the driving member, the machine body 101 provides installation conditions for the printing roller 102, and starts the driving motor through the controller to drive the printing roller 102 to rotate and print, and the adjusting component is used to adjust the The height of the printing roller 102, when the adjustment component is in use, the controller controls the driving member to operate to lift the adjustment frame 104, so that the adjustment frame 104 lifts the mounting block 103, thereby driving the printing roller 102 to move on the body 101, and realizing the adjustment of the height of the printing roller 102, and the weight (pressure) of the adjustment frame 104, the mounting block 103 and the printing roller 102 acting on the driving member is transmitted to the buffer member through the adjustment frame 104 for buffering, thereby effectively avoiding the phenomenon that the weight of the adjustment mechanism is too large and the driving member is damaged, and solves the problem that the servo motor of the existing printing press plate roller adjustment mechanism has poor buffering effect and the pressure of the adjustment mechanism acts on the servo motor to damage the internal components of the servo motor.
[0019] Among them, the sleeve 107 is fixedly connected to the adjusting frame 104 and is located at the bottom of the adjusting frame 104. The screw 106 is threadedly connected to the sleeve 107 and passes through the sleeve 107. The servo motor 105 is fixedly connected to the screw 106 and is located on the side of the screw 106 away from the sleeve 107. The output end of the servo motor 105 rotates to drive the screw 106 to rotate. Under the action of the screw 106 and the internal threads of the sleeve 107, the rotation of the screw 106 will drive the sleeve 107 to rise and fall, thereby driving the adjusting frame 104 to rise and fall. The rising and falling of the adjusting frame 104 is controlled by the rotation direction of the output end of the servo motor 105.
[0020] Secondly, the first damping rod 108 is fixedly connected to the adjusting frame 104 and is located at the bottom of the adjusting frame 104. The spring 109 is sleeved on the outside of the first damping rod 108. When the servo motor 105 drives the adjusting frame 104 to rise and fall, the first damping rod 108 also expands and contracts with the adjusting frame 104, thereby guiding the adjusting frame 104, so that the adjusting frame 104 can be lifted and lowered more smoothly, and the adjusting frame 104 will not be offset, and the printing roller 102 will not be higher at one end than at the other end. The pressure (the weight of the adjusting frame 104, the mounting block 103 and the printing roller 102 itself) transmitted to the servo motor 105 by the adjusting frame 104 is buffered by compressing the buffer medium therein through the first damping rod 108. The provision of the spring 109 further enhances the buffering effect of the first damping rod 108.
[0021] When the adjustment component is in use, the controller controls the servo motor 105 to operate, and the output end of the servo motor 105 rotates to drive the screw 106. The rotation of the screw 106 causes the sleeve 107 to rise and fall, thereby raising and lowering the adjustment frame 104, and then causing the adjustment frame 104 to raise and lower the mounting block 103, driving the printing roller 102 to move on the machine body 101, and realizing the adjustment of the height of the printing roller 102. The weight (pressure) of the adjustment frame 104, the mounting block 103 and the printing roller 102 is buffered by the first damping rod 108 and the spring 109, effectively avoiding the phenomenon that the weight of the adjustment mechanism is too large and the servo motor 105 is damaged, and solving the problem that the servo motor buffering effect of the existing printing press plate roller adjustment mechanism is poor, and the pressure of the adjustment mechanism acts on the servo motor and damages the internal components of the servo motor.
[0022] The second embodiment of the present application is:
[0023] Based on the first embodiment, please refer to Figure 2 , Figure 2 20 is a schematic diagram of the structure of the utility model. In this embodiment, the plate roller adjustment mechanism of the gravure printing machine further includes a buffer frame, and the buffer frame includes a rotating rod 201, a sliding block 202 and a second damping rod 203.
[0024] According to this specific implementation, the buffer frame is disposed between the adjustment frame 104 and the machine body 101 . The provision of the buffer frame further enhances the buffering of the pressure acting on the servo motor 105 .
[0025] Among them, the second damping rod 203 is fixedly connected to the body 101 and is located at the bottom of the body 101, the slider 202 is fixedly connected to the second damping rod 203 and is located at the top of the second damping rod 203, and the rotating rod 201 is arranged between the slider 202 and the adjusting frame 104. When the adjusting frame 104 descends, the rotating rod 201 is driven to rotate, and the rotating rod 201 rotates to drive the slider 202 to slide down, thereby compressing the second damping rod 203. The buffering medium therein is compressed by the second damping rod 203, and the pressure transmitted by the adjusting frame 104 is further buffered, thereby further strengthening the buffering of the pressure acting on the servo motor 105.
[0026] When the adjusting frame 104 descends, the rotating rod 201 is driven to rotate, and the rotating rod 201 rotates to drive the slider 202 to slide down, thereby compressing the second damping rod 203. The second damping rod 203 compresses the buffer medium therein to further buffer the pressure transmitted by the adjusting frame 104.
