[0036] The present invention will now be described in detail with reference to the accompanying drawings.
[0037] like Figure 1-4 As shown, a chrome polishing machine for gravure printing includes a body 1, which has a first region 10 and a second region 17. Both the first region 10 and the second region 17 are arranged along the length of the body 1. The first region 10 is provided with a positioning module 3 for positioning the gravure roller, which can move along the length of the first region 10. The second region 17 is provided with a chrome polishing module 5 that cooperates with the gravure roller, which can move along the length of the second region 17. A partition structure is provided between the first region 10 and the second region 17. The partition structure includes a partition plate 11 and a partition compression plate 12 that is arranged along the length of the partition plate 11 and can move. A front baffle structure is provided on the front side of the body 1. The front baffle structure includes a front opening 2 located on the front side of the body 1. A lower baffle 21 is installed on the lower half of the front opening 2. An upper baffle 22 that can be raised and lowered to cover the upper half of the front opening 2 is installed on the lower baffle 21.
[0038] During operation, the gravure roller is positioned in the first region 10. The positioning module 3 in the first region 10 can position the gravure roller in the first region 10 for polishing by the second drive and the chrome polishing die 5. During polishing, the separation structure between the first region 10 and the second region 17 can block the splashing debris. At the same time, the upper baffle 22 located in the front opening 2 can be raised, so that the splashing debris and coolant will not splash outwards, but fall into the first region 10, preventing damage to other mechanical mechanisms, thereby extending the service life of the equipment and effectively reducing the failure rate of the equipment.
[0039] Specifically, a top guide rod 16 is installed above the partition plate 11. The partition compression plate 12 includes a pair of bellows-shaped protective covers 13. The outer ends of the bellows-shaped protective covers 13 are fixed to the inner wall of the body 1, and the inner ends of the bellows-shaped protective covers 13 are connected to the chrome-polished die assembly 5. Multiple spaced connecting blocks 14 are installed on the top of the bellows-shaped protective covers 13. The connecting blocks 14 are formed with guide holes 15 that slide with the guide rod 16. Due to the blocking effect of the bellows-shaped protective covers 13, the bellows-shaped protective covers 13 can be expanded or compressed. The inner ends of the two bellows-shaped protective covers 13 are... The end is connected to the chrome polishing die 5. When the chrome polishing die 5 moves in the length direction of the second region 17, one of the bellows guards 13 is compressed and the other bellows guard 13 is stretched. Both bellows guards 13 slide with the guide rod 16 through the guide hole 15 of the connecting block 14 to achieve lateral compression or stretching. They are always kept at the top of the partition plate 11 to separate the first region 10 and the second region 17, which can reduce the amount of debris in the first partition region and the splashing of coolant into the second region 17.
[0040] Furthermore, longitudinally arranged guide strips 23 are installed on the left and right sides of the front opening 2, and guide grooves 24 are formed along the length of the guide strips 23. The left and right ends of the upper baffle 22 are respectively slidably engaged with the guide grooves 24. A baffle adjustment mechanism for adjusting the height of the upper baffle 22 is provided between the lower baffle 21 and the upper baffle 22. The baffle adjustment mechanism includes a drive rack 25 longitudinally installed on the upper baffle 22, and a rotatable drive shaft 27 is installed on the lower baffle 21. The drive shaft 27 is equipped with a front drive gear 28 that meshes with the drive rack 25 for transmission. When feeding the gravure roller, the upper baffle 22 is located in the lower half of the front opening 2, and the upper half of the front opening 2 allows the gravure roller to pass through and be fed into the positioning module 3 of the first area 10. After the material is loaded, the baffle adjustment mechanism works, driving the drive shaft 27 to rotate. The front drive gear 28 will mesh with the drive rack 25 to drive the upper baffle 22 to move up and down along the guide groove 24, which can block the upper part of the front opening 2 and block the side opening, further reducing the amount of debris in the first partition area and the splashing of coolant to the outside.
[0041] Preferably, the body 1 is equipped with an adjustable drive motor 26, the body 1 has a drive hole, a bearing seat is installed in the drive hole, and the drive shaft 27 is coaxially installed in the bearing seat. The adjustable drive motor 26 is connected to the drive shaft 27, which drives the drive shaft 27 to rotate, thereby realizing the lifting and lowering control of the upper baffle 22.
[0042] Specifically, the positioning module 3 includes a pair of spaced-apart fixing fixtures 31. The inner end of the fixing fixture 31 is equipped with a conical positioning block 32 that is inserted into the gravure roller and positions the gravure roller. The conical positioning block 32 can rotate within the fixing fixture 31. When positioning the gravure roller, since the gravure roller is a hollow structure, the conical positioning block 32 can be inserted into both ends of the gravure roller to achieve axial positioning.
[0043] Furthermore, the first region 10 is arranged along its length with a lead screw drive mechanism and a first linear guide rail 33 parallel to the lead screw drive mechanism. The lead screw drive mechanism includes a pair of drive screws 34 with opposite directions. The drive screws 34 are connected to the fixed fixture 31 through drive sleeves. The fixed fixture 31 is slidably connected to the first linear guide rail 33. When the drive screws 34 rotate under the drive of the servo motor, the threads of the two drive screws 34 are opposite, so the distance between the two fixed fixtures 31 changes. This can clamp and position the gravure roller, and can also position gravure rollers of different lengths, improving the stability of the positioning.
[0044] One of the fixed fixtures 31 is equipped with a first drive motor 4. The fixed fixture 31 is formed with a rotating groove 41. A rotating shaft 42 and a rolling bearing sleeved on the rotating shaft 42 are installed in the rotating groove 41. One end of the rotating shaft 42 is connected to a conical positioning block 32, and the other end of the rotating shaft 42 is equipped with a driven gear 43. The drive end of the first drive motor 4 is equipped with a driving gear 44. The driven gear 43 and the driving gear 44 are connected in a transmission connection. The first drive motor 4 is connected to the driven gear 43 through the transmission connection between the driving gear 44 and the driven gear 43, so that the driving gear 44 drives the driven gear 43 to rotate. The rotating shaft 42 can rotate in the rotating groove 41 of the fixed fixture 31, so as to realize the rotation of the gravure roller. During polishing, multiple areas of the surface can be polished, thereby improving the polishing quality.
[0045] Preferably, the conical positioning block 32 holds the gravure roller, and the conical positioning block 32 rotates under the drive of the rotating shaft 42 to realize the rotation of the gravure roller. The driving gear 44 and the driven gear 43 can be connected by a gear set meshing transmission method to realize the transmission connection.
[0046] Preferably, the bottom of the fixing fixture 31 is equipped with a gate-shaped bottom support plate 36, and a top cover plate 35 is installed above the first linear guide rail 33 and the transmission screw 34. There is a gap between the top cover plate 35 and the transmission screw 34. The two ends of the top cover plate 35 are installed in the body 1 of the first region 10. The top cover plate 35 can cover the first linear guide rail 33 and the transmission screw 34 to prevent the fine debris generated in the first region 10 from entering the first linear guide rail 33 and the transmission screw 34. The bottom end of the bottom support plate 36 is formed with a guide groove 37 for the top cover plate 35 to pass through. The bottom support plate 36 slides with the first linear guide rail 33 through the bottom sliding seat 53. The bottom support plate 36 is also equipped with a screw sleeve seat and is connected to the transmission screw 34. When the bottom support plate 36 moves, it has a space reserved by the guide groove 37 to cooperate with the top cover plate 35. The top cover plate 35 does not move and always keeps covering the first linear guide rail 33 and the transmission screw 34.
[0047] The second region 17 is provided with a second linear guide rail 51 along its length. The chrome polishing module 5 includes a chrome polishing sliding plate 52 and a bottom sliding seat 53 that is slidably connected to the second linear guide rail 51. A long rack 54 is also installed in the second region 17 along its length. The chrome polishing sliding plate 52 is provided with a rear drive gear 55 that meshes with the long rack 54 and a second drive motor 56 that drives the rear drive gear 55 to rotate. A motor compartment 57 is installed on the top of the chrome polishing sliding plate 52. The second drive motor 56 is located in the motor compartment 57. An inclined polishing drive plate 58 is installed on the top of the motor compartment 57. A polishing head 59 that contacts the gravure roller is installed on the polishing drive plate 58. Since multiple areas along the gravure roller need to be polished, the second drive motor 56 installed on the chrome polishing sliding plate 52 drives the rear drive gear 55 to rotate. The rear drive gear 55 meshes with the long rack 54, so that the chrome polishing sliding plate 52 can move along the length direction of the second linear guide rail 51 through the bottom sliding seat 53, so that the chrome polishing module 5 moves in the length direction of the second region 17 to polish multiple areas along the gravure roller.
[0048] It should be noted that the polishing head 59 is existing technology, and its specific structure will not be described in detail here.
[0049] Preferably, the polishing drive plate 58 is also equipped with a squeegee mechanism 6. The squeegee mechanism 6 includes a swing arm 61 capable of longitudinal swinging, and a squeegee blade 62 is installed at the outer end of the swing arm 61. The polishing drive plate 58 is equipped with a squeegee telescopic cylinder 63 capable of swinging, and the drive end of the squeegee telescopic cylinder 63 is rotatably connected to the swing arm 61. After the coolant is sprayed out and the gravure roller is cooled, the squeegee telescopic cylinder 63 drives the swing arm 61 to swing in the direction of the gravure roller. The squeegee blade 62 installed at the outer end of the swing arm 61 can contact the surface of the gravure roller to remove the surface moisture, and the impact of liquid splashing generated when the gravure roller rotates is greatly reduced.
[0050] Preferably, the polishing drive plate 58 is also equipped with a water spray head, which faces the gravure roller. The water spray head supplies water through a hose, so that the pipe will not break when the chrome polishing die 5 moves laterally.
[0051] 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.
[0052] 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.
