Description

Technical Field

[0001] This utility model relates to the field of gravure grinding machine technology, and in particular to a high-speed grinding head for a gravure grinding machine. Background Technology

[0002] Currently, in my country's gravure plate-making industry, the common plate-making process is: pre-machining - nickel electroplating - copper electroplating - copper surface grinding - copper surface polishing - electronic engraving - chrome plating - chrome surface polishing. Among these, copper plate grinding and polishing are two very important processes. Grinding is further divided into coarse grinding and fine grinding, which means that the entire process requires two grinding machines and one polishing machine.

[0003] The grinding mechanism includes a lateral drive assembly, a front-rear drive assembly, and a grinding assembly connected to the front-rear drive assembly. The lateral drive assembly is installed inside the machine base and is used to drive the front-rear drive assembly to move laterally. The grinding assembly includes a base, an electric spindle installed on the base, and a grinding stone driven and connected to the electric spindle. The front-rear drive assembly is used to drive the base to move back and forth.

[0004] When grinding a gravure roller, the grinding mechanism usually needs to move along the radial direction of the gravure roller to grind different positions. Since the grinding head itself usually has a large weight, it will generate a large inertial force when it is raised and lowered, which will cause the grinding head to be unstable and the movement accuracy to be low. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed grinding head for a gravure grinding machine that addresses the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A high-speed grinding head for a gravure grinding machine includes a grinding drive base slidably mounted on the gravure grinding machine. The grinding drive base is provided with a grinding assembly and a first guide rail arranged longitudinally at an inclination. A grinding mounting plate is slidably mounted on the first guide rail. The grinding assembly includes a grinding module mounted on the grinding mounting plate. The grinding drive base is also provided with a counterweight system, which includes a counterweight block and a rolling support member. The counterweight block is capable of longitudinal movement, and a movable connecting member is provided between the counterweight block and the grinding mounting plate. The movable connecting member is drively connected to the rolling support member.

[0008] Furthermore: the grinding module includes a grinding motor mount mounted on a grinding mounting plate, a drive motor mounted on the grinding motor mount, a grinding drive shaft mounted on the drive end of the drive motor, and a grinding head mounted on the grinding drive shaft.

[0009] Furthermore: the grinding drive base is provided with a moving drive mechanism, which includes a screw drive module. The drive end of the screw drive module is equipped with a guide drive base. The guide drive base is equipped with a cylinder drive module that drives the grinding mounting plate to move along the length direction of the first guide track. The drive end of the cylinder drive module is equipped with a connecting plate, which is connected to the grinding mounting plate.

[0010] Furthermore: the guide drive seat is formed with a longitudinal extension plate, the screw drive module moves along the length of the longitudinal extension plate, the connecting plate is equipped with a guide pin, the end of the longitudinal extension plate is formed with a guide vertical plate, the guide vertical plate is formed with a guide sliding hole coaxially aligned with the guide pin, and the guide pin slides along the guide sliding hole.

[0011] Furthermore: the first guide rail is slidably mounted with a guide slide seat, the grinding mounting plate is mounted on the guide slide seat, and the grinding motor seat is equipped with a water spray pipe for spraying water onto the gravure roller and a scraper assembly for removing water stains from the surface of the gravure roller.

[0012] Furthermore: the wiper assembly includes a longitudinally arranged wiper telescopic cylinder, which is rotatably mounted outside the drive motor, and a wiper blade is mounted on the drive end of the wiper telescopic cylinder.

[0013] Furthermore, the counterweight system also includes a longitudinal counterweight groove formed in the grinding drive seat, the longitudinal counterweight groove is provided with a counterweight guide rod for longitudinal movement of the counterweight block, and the counterweight block is equipped with a sliding sleeve that slides with the counterweight guide rod.

[0014] Furthermore: the rolling support includes a guide drive wheel installed on the top of the longitudinal counterweight groove, and the movable connecting part is a timing belt, one end of which is connected to the top of the counterweight block and the other end is connected to the guide sliding seat. The timing belt is also connected to the guide drive wheel.

[0015] Furthermore: a counterweight support plate is installed on the top of the longitudinal counterweight groove, a rotatable counterweight guide shaft is installed on the top of the counterweight support plate, a guide drive wheel is sleeved on the counterweight guide shaft, and the counterweight support plate is formed with a drive groove for the timing belt to pass through.

[0016] The beneficial effects of this utility model are as follows: When the high-speed grinding head of the motor grinder grinds the gravure roller, the grinding assembly usually needs to move along the radial direction of the gravure roller to grind different positions. When the grinding assembly moves, since there is a movable connecting piece between the counterweight and the grinding mounting plate, the counterweight will also move accordingly. The counterweight matches the weight of the grinding assembly to form a mechanical balance system, which counteracts the influence of gravity. This avoids unstable lifting speed or jamming caused by insufficient power. It reduces the impact force during buffer start-up and stop, and avoids sudden acceleration or abrupt stop of the grinding assembly due to inertia, effectively protecting the mechanical structure and transmission components. In addition, it can suppress the vibration of the grinding assembly during the lifting process, which can improve the grinding accuracy and equipment life. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-3As shown, a high-speed grinding head for a gravure grinding machine includes a grinding drive base 1 slidably mounted on the gravure grinding machine. The grinding drive base 1 is provided with a grinding assembly 10 and a first guide rail 28 arranged longitudinally at an inclination. A grinding mounting plate 11 is slidably mounted on the first guide rail 28. The grinding assembly 10 includes a grinding module mounted on the grinding mounting plate 11. The grinding drive base 1 is also provided with a counterweight system 3, which includes a counterweight block 33 and a rolling support. The counterweight block 33 is capable of longitudinal movement. A movable connector is provided between the counterweight block 33 and the grinding mounting plate 11, and the movable connector is connected to the rolling support in a transmission manner.

[0032] When the high-speed grinding head grinds the gravure roller, the grinding assembly 10 typically needs to move along the radial direction of the gravure roller to grind different positions. During this movement, the counterweight 33 moves accordingly due to the movable connector between it and the grinding mounting plate 11. The counterweight 33, by matching the weight of the grinding assembly 10, forms a mechanical balance system, counteracting the effects of gravity. This avoids unstable lifting speeds or jamming due to insufficient power, reduces the impact force during buffered start-up and stop, and prevents the grinding assembly 10 from suddenly accelerating or stopping due to inertia, effectively protecting the mechanical structure and transmission components. Furthermore, it suppresses vibration during the lifting process, improving grinding accuracy and extending equipment lifespan.

[0033] Specifically, the grinding module includes a grinding motor mount 12 mounted on a grinding mounting plate 11, a drive motor 13 mounted on the grinding motor mount 12, a grinding drive shaft 14 mounted on the drive end of the drive motor 13, and a grinding head 15 mounted on the grinding drive shaft 14. The grinding head 15 is directly mounted in the grinding drive shaft 14 of the drive motor 13, which reduces the arrangement of the transmission structure, lowers costs, improves transmission efficiency, and reduces wear on the transmission structure.

[0034] Furthermore, the grinding drive base 1 is provided with a moving drive mechanism 2, which includes a screw drive module 20. The drive end of the screw drive module 20 is equipped with a guide drive base 21. The guide drive base 21 is equipped with a cylinder drive module 22 that drives the grinding mounting plate 11 to move along the length direction of the first guide rail 28. The drive end of the cylinder drive module 22 is equipped with a connecting plate 24, which is connected to the grinding mounting plate 11. Under the dual drive of the screw drive module 20 and the cylinder drive module 22, the grinding assembly 10 can move longitudinally to achieve height adjustment. When grinding gravure rollers of different sizes, it can adaptively adapt to the height.

[0035] Specifically, the guide drive seat 21 is formed with a longitudinal extension plate 23, the screw drive module 20 moves along the length of the longitudinal extension plate 23, the connecting plate 24 is equipped with a guide pin 25, the end of the longitudinal extension plate 23 is formed with a guide upright plate 26, the guide upright plate 26 is formed with a guide sliding hole 27 coaxially aligned with the guide pin 25, and the guide pin 25 slides along the guide sliding hole 27; when the cylinder drive module 22 drives the grinding mounting plate 11 to move along the length of the first guide rail 28, the guide pin 25 installed on the connecting plate 24 will slide and engage with the guide sliding hole 27 of the guide upright plate 26; ensuring the stability and accuracy of the movement, resulting in better quality during grinding.

[0036] Specifically, a guide slide seat 29 is slidably installed on the first guide rail 28, and a grinding mounting plate 11 is installed on the guide slide seat 29. The guide slide seat 29 moves along the length of the first guide rail 28, and the grinding mounting plate 11, on which the grinding module is installed, moves synchronously to ensure the stability of the movement.

[0037] Furthermore, the grinding motor base 12 is equipped with a water spray pipe 19 for spraying water onto the gravure roller and a scraper assembly 16 for removing water stains from the surface of the gravure roller. The scraper assembly 16 includes a longitudinally arranged scraper telescopic cylinder 17, which is rotatably mounted outside the drive motor 13. A scraper blade 18 is mounted on the drive end of the scraper telescopic cylinder 17. The water spray pipe 19 faces the gravure roller, and during grinding, the sprayed water can be used for cooling and to reduce fine splashing. Driven by the scraper telescopic cylinder 17, the scraper blade 18 can move longitudinally to scrape away water stains from the surface of the gravure roller, and at the same time, it can scrape away impurities adhering to the surface.

[0038] The counterweight system 3 also includes a longitudinal counterweight groove 31 formed in the grinding drive seat 1. The longitudinal counterweight groove 31 is provided with a counterweight guide rod 32 for longitudinal movement of the counterweight block 33. The counterweight block 33 is equipped with a sliding sleeve that slides with the counterweight guide rod 32. When the grinding module moves longitudinally, the counterweight block 33 slides with the counterweight guide rod 32 through the sliding sleeve to ensure the movement stability of the counterweight block 33. The counterweight block 33 forms a mechanical balance system by matching the weight of the grinding assembly 10 to counteract its gravitational influence.

[0039] The rolling support includes a guide drive wheel 36 mounted on the top of the longitudinal counterweight groove 31, and a synchronous belt 38 as the movable connecting component. One end of the synchronous belt 38 is connected to the top of the counterweight block 33, and the other end is connected to the guide sliding seat 29. The synchronous belt 38 is also connected to the guide drive wheel 36 for transmission. A counterweight support plate 34 is mounted on the top of the longitudinal counterweight groove 31, and a rotatable counterweight guide shaft 35 is mounted on the top of the counterweight support plate 34. The guide drive wheel 36 is sleeved on the counterweight guide shaft 35, and the counterweight support plate 34 is formed with a transmission groove 37 for the synchronous belt 38 to pass through. The guide drive wheel 36 is rotatably mounted on the top of the counterweight support plate 34 via the counterweight guide shaft 35. The synchronous belt 38 is engaged with the guide drive wheel 36. When the grinding assembly 10 moves vertically downward, the counterweight block 33 will rise under the action of the synchronous belt 38; conversely, when the grinding assembly 10 rises, the counterweight block 33 will fall. This achieves balance when the grinding assembly 10 moves up and down. Stable lifting and lowering motion can ensure that the pressure of the grinding head 15 on the gravure roller is uniform, avoiding uneven grinding thickness or abnormal surface roughness caused by speed fluctuations.

[0040] In the grinding machine, the counterweight 33 is one of the key factors in achieving micron-level precision control.

[0041] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

The content of this specification should not be construed as a limitation of this utility model.
