Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromium polishing machine technology, and in particular to a polishing module for a chromium polishing machine. Background Technology
[0002] During the production of printing rollers, after electronic engraving, a thin chromium layer is plated onto the surface to protect the printing plate from abrasion by ink and doctor blades, thus improving the printing plate's durability. After chromium plating, the chromium surface needs to be polished. This process requires the use of a chromium polishing machine, a mechanical device used to polish chromium surfaces, which can improve the chromium's gloss and corrosion resistance.
[0003] In the prior art, gravure rollers are usually clamped and positioned by a clamping fixture. During grinding, the abrasive belt contacts the surface of the gravure roller to achieve grinding and polishing. Since polishing requires polishing multiple areas of the gravure roller, the clamping fixture can rotatably drive the gravure roller to rotate. When rotating, since the abrasive belt is in contact with the gravure roller, it may cause the abrasive belt to roll back synchronously, affecting the polishing. Utility Model Content
[0004] The purpose of this invention is to provide a polishing module for a chromium polishing machine, addressing the shortcomings of existing technologies.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A polishing module for a chrome polishing machine includes a polishing head facing a gravure roller and a polishing drive seat for mounting the polishing head. The polishing drive seat is equipped with a drive wheel shaft for unwinding a sanding belt and a driven wheel shaft for winding the sanding belt. The polishing head is provided with a polishing station that contacts the gravure roller and a pressing channel for guiding the sanding belt through. The pressing channel is provided with a guide baffle and a guide pressure seat that cooperates with the guide baffle. The guide pressure seat can move closer to or further away from the guide baffle, and the sanding belt passes between the guide pressure seat and the guide baffle.
[0007] Furthermore: there are two pressing channels, and both pressing channels are equipped with guide baffles and guide pressure seats that cooperate with the guide baffles.
[0008] Furthermore, the polishing head also includes a first drive frame and a second drive frame connected to each other. The polishing station is set on the first drive frame, which is equipped with a pair of spaced-apart wedge pulleys that are driven by the sanding belt. The pressing channel is set on the second drive frame.
[0009] Furthermore: the second drive frame is provided with a passage groove for the sanding belt to pass through, and the second drive frame is provided with a telescopic cylinder that drives the guide pressure seat to move closer to or away from the guide baffle.
[0010] Furthermore, the second drive frame is also equipped with a drive wheel that engages with the through groove and provides drive for the sand belt to move.
[0011] Furthermore: the polishing drive seat is equipped with a drive motor that is driven and coupled with the driven wheel shaft.
[0012] Furthermore, it also includes an inclined drive mounting plate, a drive frame on which a polishing drive seat is mounted, and a first linear drive mechanism on which the drive frame is moved along the length of the drive mounting plate toward or away from the gravure roller.
[0013] Furthermore: the first linear drive mechanism is one of the following: a lead screw drive mechanism, a linear module mechanism, or a telescopic cylinder mechanism.
[0014] Furthermore, the drive frame is provided with a second linear drive mechanism parallel to the first linear drive mechanism. The second linear drive mechanism drives the polishing drive seat to move closer to or away from the gravure roller along the length direction of the drive frame.
[0015] The beneficial effects of this utility model are as follows: The sanding belt is unwound from the drive wheel shaft, passes through the polishing station and the pressing channel, and contacts the gravure roller at the polishing station to polish the surface of the gravure roller; when the gravure roller rotates, in order to prevent the sanding belt from rolling back at the polishing station, the guide pressure seat located in the pressing channel works. The guide pressure seat is close to the guide baffle, and the sanding belt passing through the pressing channel will be clamped. At this time, the sanding belt will be prevented from rolling back, ensuring the stability of the sanding belt. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings.
[0031] As shown in the figure
[0032] A polishing module for a chrome polishing machine includes a polishing head facing a gravure roller and a polishing drive seat 2 for mounting the polishing head. The polishing drive seat 2 is equipped with a drive wheel shaft 21 for unwinding a sanding belt 28 and a driven wheel shaft 22 for winding the sanding belt 28. The polishing head is provided with a polishing station 26 that contacts the gravure roller and a pressing channel 32 for guiding the sanding belt 28 through. The pressing channel 32 is provided with a guide baffle 33 and a guide pressure seat 34 that cooperates with the guide baffle 33. The guide pressure seat 34 can approach or move away from the guide baffle 33. The sanding belt 28 passes between the guide pressure seat 34 and the guide baffle 33.
[0033] The sanding belt 28 is unwound by the drive shaft 21, passes through the polishing station 26 and the pressing channel 32, and contacts the gravure roller through the polishing station 26 to polish the surface of the gravure roller. When the gravure roller rotates, in order to prevent the sanding belt 28 from rolling back at the polishing station 26, the guide pressure seat 34 located in the pressing channel 32 works. The guide pressure seat 34 is close to the guide baffle 33, and the sanding belt 28 passing through the pressing channel 32 will be clamped. At this time, the sanding belt 28 will be prevented from rolling back, ensuring the stability of the sanding belt 28.
[0034] Preferably, both the drive shaft 21 and the driven shaft 22 are fitted with a reel roller 23 for mounting the reel. After the sanding belt 28 reel is fitted onto the reel roller 23, the reel roller 23 can be fixed.
[0035] Preferably, there are two pressing channels 32, each equipped with a guide baffle 33 and a guide pressure seat 34 that cooperates with the guide baffle 33. One pressing channel 32 is located between the sanding belt 28 advancing to the polishing station 26 and the drive wheel shaft 21, while the other pressing channel 32 is located between the sanding belt 28 polishing station 26 and the driven wheel shaft 22. When the sanding belt 28 is pressed, the guide pressure seats 34 of the two pressing channels 32 cooperate with the guide baffle 33 to achieve two-section pressing of the sanding belt 28, further improving its clamping stability and further reducing the probability of the sanding belt 28 rewinding.
[0036] Furthermore, the polishing head also includes a first drive frame 24 and a second drive frame 3 connected to each other. The polishing station 26 is set on the first drive frame 24, which is equipped with a pair of spaced-apart wedge pulleys 25. The wedge pulleys 25 are driven and engaged with the abrasive belt 28. The pressing channel 32 is set on the second drive frame 3. The two spaced-apart wedge pulleys 25 allow the abrasive belt 28 to pass through sequentially. The abrasive belt 28 forms a polishing surface between the two wedge pulleys 25 that can contact the gravure roller. When the abrasive belt 28 contacts the gravure roller, the pressing channel 32 clamps it tightly. Subsequently, the gravure roller rotates, realizing the polishing and grinding treatment of the surface of the gravure roller.
[0037] The second drive frame 3 is provided with a through groove 36 for the sanding belt 28 to pass through. The second drive frame 3 is provided with a pressing telescopic cylinder 35 that drives the guide pressure seat 34 to move closer to or away from the guide baffle 33. The sanding belt 28 passes through the first pressing channel 32, then through the first through groove 36, and enters the polishing station 26. It then cooperates with two wedge pulleys 25 in sequence to form a plane that contacts the gravure roller. The sanding belt 28 then continues to pass through another through groove 36 and another pressing channel 32, and is wound up by the driven wheel shaft 22.
[0038] Furthermore, the second drive frame 3 is also provided with a transmission wheel 31 that cooperates with the through groove 36 to drive the sanding belt 28. The provision of multiple transmission wheels 31 can further improve the transmission stability of the sanding belt 28 and prevent the sanding belt 28 from becoming too loose during transmission.
[0039] The polishing drive base 2 is equipped with a drive motor 27 that is driven and cooperates with the driven wheel shaft 22. The drive motor 27 can drive the driven wheel shaft 22 to rotate through the belt transmission mechanism, thereby rotating and winding up the used sanding belt 28.
[0040] It also includes an inclined drive mounting plate 1, a drive frame 11, a polishing drive seat 2 mounted on the drive frame 11, and a first linear drive mechanism 12 that drives the drive frame 11 to move along the length of the drive mounting plate 1 to approach or move away from the gravure roller. Under the drive of the first linear drive mechanism 12, the drive frame 11 located at the top of the drive mounting plate 1 can move in the radial direction of the gravure roller to approach or move away from it.
[0041] Preferably, the first linear drive mechanism 12 is one of a screw drive mechanism, a linear module mechanism, or a telescopic cylinder mechanism. Screw drive mechanisms, linear module mechanisms, and telescopic cylinder mechanisms are common mechanisms, and their specific structures will not be described in detail here. The first linear drive mechanism 12 also includes a first linear guide rail 13 for mounting the drive mounting plate 1. A first linear slide seat 14 is slidably mounted on the first linear guide rail 13. The first linear slide seat 14 is connected to the drive frame 11, which can improve the movement stability of the drive frame 11.
[0042] Furthermore, the drive frame 11 is provided with a second linear drive mechanism 15 parallel to the first linear drive mechanism 12. The second linear drive mechanism 15 drives the polishing drive seat 2 to move closer to or away from the gravure roller along the length direction of the drive frame 11. Similarly, a second linear guide rail 16 is arranged along the length direction of the drive frame 11, and a second linear sliding seat 17 is slidably mounted on the second linear guide rail 16. The second linear sliding seat 17 is connected to the polishing drive seat 2. The second linear drive mechanism 15 drives the polishing drive seat 2 to move along the second linear guide rail 16 through the second linear sliding seat 17, enabling it to move in the radial direction of the gravure roller, closer to or away from the gravure roller, and further fine-tune its radial position.
[0043] Preferably, the second linear drive mechanism 15 is one of a screw drive mechanism, a linear module mechanism, or a telescopic cylinder mechanism.
[0044] 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.
[0045] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
