DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1: Figure 1-7 As shown, a grinding head for gravure processing of a printing plate roller of the utility model comprises a first grinding plate 1 and a mounting plate 11, wherein the first grinding plate 1 is mounted on the lower end of the mounting plate 11, and a mounting frame 12 matching the first grinding plate 1 is mounted on the lower end of the mounting plate 11, and side grinding mechanisms are mounted on both left and right sides of the lower end of the mounting plate 11, wherein the side grinding mechanisms comprise a plurality of arc-shaped rods 13 rotatably connected to the mounting frame 12, and a plurality of the arc-shaped rods 13 are elastically hinged with grinding blocks 14 at the other ends, and a plurality of the arc-shaped rods 13 on the same side are commonly connected with a transmission rod 15, and a driving mechanism is commonly mounted on two of the transmission rods 15;

[0026] A plurality of ventilation slots are provided between the mounting plate 11 and the side grinding mechanism, and the plurality of ventilation slots are interconnected. An exhaust fan 17 connected to the ventilation slots is installed at the upper end of the mounting plate 11, and a dust collection assembly is installed inside the ventilation slots 16.

[0027] During installation, the mounting plate 11 is connected to the gravure printing plate roller processing equipment. In the initial state, the upper side of the grinding block 14 abuts against the lower end of the mounting plate 11. Such a plurality of grinding blocks 14 are flush with the first grinding plate 1, which is convenient for storing the grinding head when not in use.

[0028] When the plate roller needs to be ground, the two transmission rods 15 are driven by the driving mechanism to rotate in opposite directions, so that the ends of the two arc-shaped rods 13 move downward. The downward rotation of the arc-shaped rods 13 will cause the grinding block 14 to rotate downward. Since the grinding block 14 is elastically hinged with the arc-shaped rods 13, it will be slightly deflected when the grinding block 14 is attached to the plate roller, so that the grinding block 14 and the first grinding plate 1 are attached to the plate roller, and then the plate roller is ground in the process of driving the plate roller to rotate in coordination with the processing equipment. When encountering plate rollers of different sizes, the driving mechanism can drive the arc-shaped rods 13 to rotate at different angles to control the rotation angle of the grinding block 14, so that all sizes of plate rollers can be abutted against the first grinding plate 1 and the two side grinding mechanisms, and repeated grinding is performed to improve the grinding efficiency; at the same time, the exhaust fan 17 located between the first grinding plate 1 and the side grinding mechanism can cooperate with the dust accumulation component to suck the flying catkins at the grinding place of the side grinding mechanism and the first grinding plate 1 to avoid adhering to the surface of the plate roller and affecting the subsequent grinding. .

[0029] The utility model can control the rotation of the driving mechanism according to the different sizes of the plate roller, so that the transmission rod 15 drives the arc rod 13 and the grinding block 14 to rotate into an arc, and cooperates with the first grinding plate 1 to grind the plate roller multiple times, thereby improving the grinding efficiency.

[0030] Embodiment 2: Further improvement is made on the basis of Embodiment 1, the grinding block 14 includes an elastic hinge plate 20 elastically hinged to the arc rod 13, a plurality of first springs 21 are installed at the lower end of the elastic hinge plate 20, a second grinding plate 22 is installed together with the plurality of first springs 21, and a rubber column 23 is installed between the second grinding plate 22 and the elastic hinge plate 20.

[0031] The plurality of first springs 21 and the plurality of rubber columns 23 play an elastic connection role for the second grinding plate 22, so that the second grinding plate 22 can naturally fit with the plate roller. At the same time, the connection of the rubber column 23 can make the first grinding plate 22 deviate and play a connecting role at the same time, so as to prevent the second grinding plate 22 from being away from the elastic hinge plate 20.

[0032] The driving mechanism includes a transmission gear 24 fixedly mounted on the transmission rod 15 , a driving gear 25 meshing with the transmission gear 24 is rotatably connected inside the mounting plate 11 , and a brake motor 26 transmission-connected to the driving gear 25 is installed inside the mounting plate 11 .

[0033] The brake motor 26 drives the driving gear 25 to rotate, and then drives the two transmission gears 24 to rotate in opposite directions, which will drive the two transmission rods 15 to rotate in opposite directions, and then control the two grinding blocks 14 to move closer to or away from each other.

[0034] The dust collection assembly includes a filter plate 27, the ventilation slot includes an air inlet slot 28, a connecting slot 29 and an air outlet slot 30 that are interconnected, the air outlet slot 30 is connected to the exhaust fan 17, the filter plate 27 is fixedly installed inside the barrel slot 29, and an inclined surface 31 is provided between the air inlet slot 28 and the connecting slot 29. The filter plate 27 can block flying catkins entering the air inlet slot 28 and the connecting slot 29, so that wind and air pass through the filter plate 27 and are extracted by the exhaust fan 17, so that the flying catkins of the grinding can be prevented from affecting the subsequent grinding.

[0035] The transmission rod 15 is provided with a plurality of threaded sections 32 matching the connecting grooves 29, and the threaded sections 32 are threadedly connected with scraper strips 33 abutting against the filter plate 27. When the transmission rod 15 is adjusted to restore the initial state after the plate roller is processed, the threaded sections 32 will be driven to rotate, and then the scraper strips 33 slidably connected to the mounting frame 12 will scrape the surface of the filter plate 27 to clean the accumulated dust, and the dust will slide down from the inclined surface, and at this time, a dust collecting device such as a garbage bag can be used to collect the dust.

[0036] The two side grinding mechanisms are arranged to support each other left and right, and the two side grinding mechanisms are staggered front and back.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
