Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the automatic cleaning device for rubber blanket of printing machine disclosed by the invention is arranged on a printing frame 2 at one side of a rubber blanket roller 1, and a driving roller 3 with two ends rotatably arranged on the printing frame 2 is arranged in the automatic cleaning device. The driving roller 3 is arranged in parallel with the rubber blanket printing roller 1, one end of the driving roller 3 penetrates through the printing machine frame 2, and the other side of the printing machine frame 2 is connected with a servo motor 4 for driving the printing machine frame to rotate. The driving roller 3 both ends homogeneous connection that is in print frame 2 has the same drive rod 5 of length, and two drive rods 5 set up on the circumference outer wall of driving roller 3 along the same radial of driving roller 3. A cleaning roller 6 for cleaning the rubber printing roller 1 is arranged between one ends, far away from the driving roller 3, of the two driving rods 5, and the two ends of the cleaning roller 6 are rotatably connected with the two groups of driving rods 5 through bearings arranged at the end parts of the driving rods 5. The cleaning roller 6 is parallel to the driving roller 3 when being connected with the mounting rod, and the driving roller 3 can drive the cleaning roller 6 to rotate around the axial direction of the driving roller 3 when rotating. It is worth mentioning that the farthest distance from the cleaning roller 6 to the axial direction of the driving roller 3 is such that the track of the cleaning roller 6 is circumscribed with the blanket cylinder 1 when the driving roller 3 rotates.
Referring to fig. 2 and 3, a cloth collecting roller 7 parallel to the driving roller 3 is further disposed directly above the driving roller 3, and both ends of the cloth collecting roller 7 are rotatably mounted on the printing frame 2 while one end thereof extends to the other side of the printing frame 2 and is connected to a driving motor 8. A closed cleaning cloth 9 for scrubbing the rubber printing roller 1 is sleeved between the cloth collecting roller 7 and the cleaning roller 6. When the cleaning cloth 9 is sleeved on the cloth collecting roller 7, the cleaning cloth passes through a gap between the cloth collecting roller 7 and the driving roller 3, in order to enable the rotating cloth collecting roller 7 to smoothly drive the cleaning cloth 9 to rotate, the clamping cylinder 10 is rotatably sleeved on the circumferential outer wall of the driving roller 3 between the two driving rods 5, and two surfaces of the cleaning cloth 9 respectively abut against the clamping cylinder 10 and the cloth collecting roller 7 when passing through the gap between the clamping cylinder 10 and the cloth collecting roller 7. When the servo motor 4 drives the driving roller 3 to rotate until the cleaning roller 6 is tangent to the rubber printing roller 1, the cleaning cloth 9 outside the cleaning roller 6 is attached to the rubber printing roller 1, and further when the rubber printing roller 1 and the cloth collecting roller 7 rotate, the cleaning cloth 9 can wipe and clean the surface of the rubber printing roller 1, and it is worth explaining that the rotation direction of the cloth collecting roller 7 is opposite to the rotation direction of the rubber printing roller 1.
Referring to fig. 3, a cleaning unit for cleaning the cleaning cloth 9 wiped off the blanket roll 1 is provided below the driving roll 3. The cleaning assembly comprises a liquid containing box 11 arranged below the driving roller 3 and a winding roller 12 rotatably arranged in the liquid containing box 11. The liquid containing box 11 is positioned below the driving roller 3 and is positioned at one side of the driving roller 3 far away from the rubber printing roller 1, cleaning liquid is contained in the liquid containing box 11, and the bottom edge of the winding roller 12 is positioned below the liquid level of the cleaning liquid. After the cloth collecting roller 7 is wound, the cleaning cloth 9 is wound around the winding roller 12 with one end extended and immersed in the cleaning liquid. An ultrasonic generator 13 is also arranged in the cleaning liquid of the liquid containing box 11.
When the cleaning cloth 9 wiped by the rubber printing roller 1 is conveyed into the liquid containing box 11 by the rotation of the cloth collecting roller 7, the cleaning cloth is soaked in the cleaning liquid, and simultaneously, the ultrasonic sound generator is started to efficiently vibrate and remove ink dirt and the like adhered on the cleaning cloth 9, so that the cleaning cloth 9 can keep a clean state when being conveyed out of the liquid containing box 11, and the rubber printing roller 1 is wiped and cleaned circularly.
Referring to fig. 3 and 4, a box cover 14 is further disposed at an open top of the liquid containing box 11, two sets of through grooves 15 for allowing the cleaning cloth 9 to enter and exit are formed in the box cover 14, a wiping colloid 16 is bonded on the inner edge of the through groove 15 for allowing the cleaning cloth 9 to exit the liquid containing box 11, and the cleaning cloth 9 is attached to the wiping colloid 16 when exiting the liquid containing box 11, so that the wiping colloid 16 can scrape off part of the cleaning liquid attached to the cleaning cloth back to the liquid containing box 11.
The implementation principle and the beneficial effects of the embodiment are as follows: after the automatic cleaning device is installed, the rotation angle of the servo motor 4 is firstly adjusted, so that the servo motor 4 can drive the cleaning roller 6 to rotate to be in contact with the rubber printing roller 1 by virtue of the driving roller 3 after being started, and the cleaning cloth 9 on the cleaning roller 6 is in contact with the rubber printing roller 1. After the driving motor 8 is started, the cloth collecting roller 7 is used for enabling the cleaning cloth 9 to move in the reverse direction of the rubber printing roller 1, and the cleaning cloth 9 wipes and cleans the rubber printing roller 1 in the contact rotation process of the rubber printing roller 1. Meanwhile, the cleaned cleaning cloth 9 enters the liquid containing box 11 where the winding roller 12 is located for soaking in the rotating process, and the cleaning liquid is used for efficiently cleaning ink stains and the like on the cleaning cloth 9 by virtue of ultrasonic vibration generated by the ultrasonic generator 13, so that the cleaned cleaning cloth 9 can still be effectively cleaned when rotating to be in contact with the rubber printing roller 1 again; after the cleaning is finished, the servo motor 4 can be controlled to rotate to the initial angle, so that the cleaning cloth 9 is separated from the rubber printing roller 1, the driving motor 8 is stopped, and the cleaning liquid in the liquid containing box 11 can be replaced.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
