A driving component is provided at the lower end of the printing roller support seat 601; the quick disassembly and assembly mechanism also includes grooves 605 respectively arranged on the inner side surfaces of the limit blocks 603, and springs 606 are arranged in the grooves 605. The inner ends of the springs 606 are respectively fixedly connected to the corresponding inner wall surfaces of the slide slot 602 adjacent to the same side; the screw holes longitudinally symmetrically arranged at the right end of the upper surface of the horizontal plate of the left fixed seat 200 are threadedly connected with locking bolts 900, and the lower ends of the locking bolts 900 are in conflict with the upper surface of the insertion rod 300; the inner ends of the outer side surfaces of the limit blocks 603 are tilted from the inside to the outside.

[0022] like Figure 2-4 As shown, an electric telescopic rod 500 is provided in the installation grooves arranged in the middle of the upper surface of the vertical plate of the right fixed seat 100 and the left fixed seat 200. The upper ends of the telescopic ends of the electric telescopic rod 500 are respectively fixedly connected to the top wall surface of the sliding sleeve 400 adjacent to the same side, and the electric telescopic rod 500 is electrically connected to the external single-chip computer.

[0023] like Figure 1-4 As shown, the driving assembly includes assembly grooves 700 respectively arranged at the middle part of the lower end of the printing roller support seat 601, and a group of sliding groove openings 602 located on the printing roller support seat 601 are respectively connected to the assembly grooves 700 adjacent to the same side. The middle part of the assembly grooves 700 is rotatably connected with a rotating rod 701, and the outer ends of the rotating rods 701 respectively pass through the through holes correspondingly arranged on the outer surface of the printing roller support seat 601 where they are located and extend to the outside.

[0024] The working principle of a printing roller support provided by the utility model is as follows: when it is necessary to disassemble or assemble the printing roller, the relevant staff only needs to rotate the rotating rod 701 on any side, and the rotation of the rotating rod 701 drives the corresponding wire drum 702 to rotate synchronously, and when the wire drum 702 rotates, the corresponding limit block 603 is pulled by the pull rope 703 to overcome the elastic force of the spring 606 and retract into the sliding groove mouth 602, so that the limit block 603 is separated from the limit groove 604, and at this time, the printing roller support seat 601 on this side is pulled outward, and the printing roller can be removed, so that the printing roller can be removed. The brush roller is more convenient to disassemble and assemble, which improves the work efficiency of relevant staff, reduces invalid working hours, and solves the problem of thread slippage during frequent rotation of the thread. After removing the printing roller, the relevant staff loosens the rotating rod 701, and the limit block 603, the pull rope 703 coil 702 and the rotating rod 701 are reset under the action of the rebound force of the spring 606, and then one end of the printing roller to be installed is connected to the fixed printing roller support seat 601, and then the removed printing roller support seat 601 is connected to one end of the printing roller, and finally the printing roller support seat is fixed. 601 is movably connected with the corresponding socket 600. During the connection process, the inclined surface of the limit block 603 will first contact and slide relatively with the outer corner of the socket 600, so that the limit block 603 can overcome the elastic force of the spring 606 and retract into the sliding groove 602. After the printing roller support seat 601 is completely engaged with the corresponding socket 600, the limit block 603 is reset under the action of the rebound force of the spring 606 and movably connected to the limit groove 604, and the installation of the printing roller is completed. When the height of the printing roller needs to be adjusted, only the relevant work is required. The operation of the electric telescopic rod 500 is regulated by an external single-chip computer. The telescopic end of the electric telescopic rod 500 moves synchronously to mobilize the sliding sleeve 400 to move upward, thereby realizing the height adjustment of the printing roller. When it is necessary to adapt to printing rollers of different lengths, only one of the right fixing seat 100 and the left fixing seat 200 needs to be pulled to make the insertion rod 300 slide relative to the slot. After the distance between the right fixing seat 100 and the left fixing seat 200 reaches a suitable value, the right fixing seat 100 and the left fixing seat 200 are tightened, thereby meeting the needs of fixing and installing printing rollers of different specifications.

[0025] like Figure 2-4 As shown, guide wheels 800 are rotatably connected in the rotating grooves arranged at the upper side of the front end and the lower side of the rear end of the assembly groove 700. The guide wheels 800 are respectively arranged to cooperate with the adjacent pull ropes 703 on the same side to reduce the friction coefficient of the pull rope 703 when it is working, thereby extending the service life of the pull rope 703 to a certain extent.
