Description

Technical Field

[0001] This utility model relates to the field of rubber roller surface polishing technology, and in particular to a rubber roller surface polishing device for printing. Background Technology

[0002] A printing roller surface polishing device is a specialized piece of equipment designed to polish and treat the surface of printing rollers. The main purpose of these devices is to restore the smoothness, uniformity, and roughness of the roller surface to ensure even ink transfer during printing, thereby improving print quality. These devices typically include clamping mechanisms to secure and hold the roller to be polished, ensuring it does not move or rotate during the polishing process. The polishing tools are usually grinding wheels, belts, or discs, which contact and polish the roller surface by rotating or moving.

[0003] The existing system has a spring structure installed between the grinding plate and the frame. During the grinding process, the grinding plate will vibrate violently. As a result, the grinding plate will frequently come into contact with the surface of the printing roller, causing some areas of the printing roller to be over-grinded, while the parts that have less contact with the grinding plate will not be effectively ground. This large machine can only perform preliminary grinding on the printing roller, which greatly reduces the grinding effect.

[0004] An existing patent (publication number: CN217648068U) discloses a printing roller polishing tool, which includes a bracket on which a semi-circular polishing plate and a semi-circular cleaning plate are fixedly mounted. It can polish the surface of the printing roller using a semi-circular sandpaper mounted on the semi-circular polishing plate, suitable for deep polishing of the printing roller, and avoids uneven polishing caused by mechanical vibration.

[0005] To address the aforementioned issues, while existing patents suggest that the surface of the printing roller can be sanded using a semi-circular sandpaper mounted on a semi-circular sanding plate, the sanding process generates dust that cannot be cleaned. This results in the dust being suspended in the air, potentially impacting the surrounding environment. Summary of the Invention

[0006] The purpose of this utility model is to provide a surface polishing device for printing rubber rollers, which can polish the outer surface of the rubber roller body. At the same time, through the air suction component provided on the mounting base, the negative pressure fan provided in the fixing plate is started, so that negative pressure is generated in the air suction component. With the cooperation of the negative pressure chamber, the air inlet on the mounting base sucks in the dust generated during polishing. When the dust passes through the filter screen, it can be filtered, so that the amount of dust carried in the exhaust air is reduced, improving practicality and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a printing roller surface polishing device, comprising a device base, a fixing frame fixed on the left side of the device base, a connecting block slidably connected inside the fixing frame, a polishing mechanism for polishing the roller on the right side of the connecting block, and a clamping mechanism for clamping the roller at one end of the device base.

[0008] The grinding mechanism includes an adjusting electric cylinder, which is fixed to the right side of the connecting block by bolts. The telescopic end of the adjusting electric cylinder is fixed with a mounting base. The mounting base has two negative pressure chambers inside. Two suction components that communicate with the negative pressure chambers are fixed on the outer surface of the mounting base. Two filter screens are installed horizontally inside the suction components.

[0009] Preferably, the inner wall of the suction component is fixed with a fixing plate, and two negative pressure fans are fixed inside the fixing plate.

[0010] Preferably, both ends of the two filter screens are fixed with a locking block that is inserted and connected to the inner wall of the air intake component.

[0011] Preferably, a grinding plate is installed on the inner wall of the mounting base, and a connector that is fixedly connected to the mounting base is provided on one side of the grinding plate.

[0012] Preferably, the outer surface of the mounting base is fitted with fixing bolts that are threadedly connected to the grinding plate.

[0013] Preferably, a drive motor is fixed to the other end of the device base by bolts, and a rubber roller body is arranged horizontally inside the device base.

[0014] Preferably, the clamping mechanism includes a clamping electric cylinder, which is fixed to one end of the device base by bolts. Both the clamping electric cylinder and the output end of the drive motor are fixed with clamping components, and the outer surface of the clamping component is threaded with two limiting screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The grinding mechanism can grind the outer surface of the rubber roller body. At the same time, the suction device on the mounting base and the negative pressure fan in the fixing plate are activated to generate negative pressure in the suction device. With the cooperation of the negative pressure chamber, the air inlet on the mounting base sucks in the dust generated during grinding. When the dust passes through the filter screen, it can be filtered, reducing the amount of dust carried in the exhaust air and improving its practicality.

[0017] 2. Through the clamping mechanism, the clamping electric cylinder drives another clamping component to move horizontally and contact the other end of the rubber roller body, thereby limiting the rubber roller body. Then, the limiting screw on the rubber roller body is tightened so that the end of the limiting screw contacts the outer surface of the rubber roller body, thereby fixing the rubber roller body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

The suction components 43 have two filter screens 44 installed horizontally inside. The inner wall of the suction components 43 is fixed with a fixing plate 45. The fixing plate 45 has two negative pressure fans 46 fixed inside. Both ends of the two filter screens 44 are fixed with a locking block 47 that is inserted and connected to the inner wall of the suction components 43. The inner wall of the mounting base 41 is equipped with a grinding plate 48. One side of the grinding plate 48 is fixed with a connector 49 that is inserted and connected to the mounting base 41. The outer surface of the mounting base 41 is equipped with a fixing bolt 5 that is threadedly connected to the grinding plate 48.

[0029] By adopting the above technical solution, before using the printing roller surface polishing device, the device base 1 is first placed in a suitable position, and the roller body 7 is driven to rotate by the drive motor 6. The adjusting electric cylinder 4 on the connecting block 3 drives the mounting base 41 to move horizontally, so that the polishing plate 48 and the outer surface of the roller body 7 come into contact. Under the action of the roller body 7 being driven to rotate, the outer surface of the roller body 7 can be polished. At the same time, through the suction component 43 on the mounting base 41, the negative pressure fan 46 in the fixing plate 45 is started, so that negative pressure is generated in the suction component 43. With the cooperation of the negative pressure chamber 42, the inlet on the mounting base 41... The air inlet draws in the dust generated during grinding. The dust is filtered as it passes through the filter screen 44, reducing the amount of dust carried in the exhaust air and improving its practicality. The filter screen 44 can be disassembled using the locking block 47 on it. The inner shell of the fixing frame 2 is equipped with a screw drive mechanism, which is driven by a motor to rotate the screw. When the screw rotates, it moves the threaded connecting block 3, facilitating grinding of different positions on the rubber roller body 7. By unscrewing the fixing bolt 5 on the mounting base 41, the grinding plate 48 can be released. With the cooperation of the connecting piece 49, the grinding plate 48 can be disassembled for easy replacement.

[0030] Specifically, such as Figures 1-4As shown, the other end of the device base 1 is fixed with a drive motor 6 by bolts. The rubber roller body 7 is arranged horizontally inside the device base 1. The clamping mechanism includes a clamping electric cylinder 8. The clamping electric cylinder 8 is fixed to one end of the device base 1 by bolts. The output ends of the clamping electric cylinder 8 and the drive motor 6 are both fixed with clamping parts 81.

[0031] By adopting the above technical solution, the rubber roller body 7 to be processed is first fixed, one end of the rubber roller body 7 is inserted into the clamping part 81 on the drive motor 6, and the clamping electric cylinder 8 drives another clamping part 81 to move horizontally and contact the other end of the rubber roller body 7, thereby limiting the rubber roller body 7. Then, the limiting screw 82 on the rubber roller body 7 is tightened so that the end of the limiting screw 82 contacts the outer surface of the rubber roller body 7, thereby fixing the rubber roller body 7.

[0032] Working principle: The rubber roller body 7 to be processed is fixed, and one end of the rubber roller body 7 is inserted into the clamping part 81 on the drive motor 6. The clamping electric cylinder 8 drives the other clamping part 81 to move horizontally and contact the other end of the rubber roller body 7, thereby limiting the rubber roller body 7. The drive motor 6 drives the rubber roller body 7 to rotate. The adjusting electric cylinder 4 on the connecting block 3 drives the mounting base 41 to move horizontally, so that the grinding plate 48 contacts the outer surface of the rubber roller body 7. Under the action of the rubber roller body 7 being driven to rotate, the outer surface of the rubber roller body 7 is ground. Simultaneously, through the suction component 43 provided on the mounting base 41, the negative pressure fan 46 provided in the fixing plate 45 is started, causing negative pressure to be generated in the suction component 43. With the cooperation of the negative pressure chamber 42, the air inlet on the mounting base 41 sucks in the dust generated during grinding. When the dust passes through the filter screen plate 44, it can be filtered. The filter screen plate 44 can be disassembled by the locking block 47 provided on the filter screen plate 44. By unscrewing the fixing bolt 5 on the mounting base 41, the fixing of the grinding plate 48 can be released. With the cooperation of the connecting piece 49, the grinding plate 48 can be disassembled.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
