Description

Technical Field

[0001] The utility model belongs to the technical field of gravure printing plate roller processing, and particularly relates to a gravure printing plate roller processing device. Background Art

[0002] The gravure roller is a key component in gravure printing. Its surface typically features tiny dimples that hold the ink, enabling the printing process. The equipment used to process the gravure roller is primarily responsible for etching or engraving these dimples into the roller's surface. Traditional, manual or low-precision engraving methods can fail to produce fine patterns and lines, resulting in unclear or distorted prints. Furthermore, equipment without automatic engraving capabilities requires increased manual intervention, leading to low production efficiency.

[0003] Secondly, equipment without positioning and automatic rotation functions cannot accurately control the position and movement of the roller, and may require manual position adjustment or operation. It may also cause the engraving position to shift, affecting the accuracy of the pattern, resulting in inaccurate alignment during printing and printing errors.

DETAILED DESCRIPTION

[0027] The following is a clear and complete description of the technical solution of this utility model. Obviously, the embodiments described are part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0028] Example

[0029] See attached Figure 1-5 , a gravure plate roller processing device, including a main body 1, a driving mechanism and a size changing mechanism, wherein,

[0030] The driving mechanism includes a first motor 2, a lead screw 3, a slide 4, a laser device 5, and a rotation mechanism. The first motor 2 is fixedly mounted on the main body 1, with one end of the lead screw 3 fixedly connected to the output end of the first motor 2. The slide 4 is mounted on the main body 1 and slidably connected to the main body 1. The laser device 5 is fixedly mounted on the slide 4. The rotation mechanism includes a roller 6, a bidirectional push rod 7, a second motor 8, and a clamping block 9. The bidirectional push rod 7 is fixedly mounted on the main body 1, with both output ends of the bidirectional push rod 7 fixedly connected to the clamping block 9. The second motor 8 is fixedly mounted on the clamping block 9, which is mounted on the main body 1 and slidably connected to the main body 1. During use, the first motor 2 is driven to directly drive the lead screw 3 to rotate within the main body 1, thereby causing the slide 4 to slide in the first slide groove 20 of the main body 1, so that the laser device 5 fixedly mounted on the slide 4 can laser engrave the roller 6, completing the processing of the roller 6.

[0031] The rotating mechanism includes a roller body 6, a two-way push rod 7, a second motor 8 and a clamping block 9. When in use, the two-way push rod 7 is in operation, pushing the clamping block 9 to slide in the second slide groove 21 of the main body 1. While the clamping block 9 slides, the balance plate 22 at the bottom of the clamping block 9 slides in the second slide groove 21, and the second motor 8 is driven, so that the size changing mechanism fixedly installed at the output end of the second motor 8 is operated. As the electric push rod contracts, the extrusion pad 14 is in close contact with the two end surfaces of the roller body 6, so that the anti-slip strip 15 can be firmly in contact with the two end surfaces of the roller body 6, thereby completing the rotation of the roller body 6. At the same time, the operator operates the control panel 18 on the main body 1, and then observes the display screen 19 to directly and precisely control the laser engraving of the roller body 6.

[0032] In this embodiment, the size replacement mechanism includes a fixing frame 10, an insert plate 11, a connecting block 12 and a rotating plate 13. During use, due to the different sizes of the roller body 6, the fixed mechanism cannot meet the requirements of multiple sizes. At this time, the insert plate 11 can be replaced, so that the insert plate 11 is picked up and the insert plate 11 on the insert plate 11 directly enters the insertion hole 28 of the clamping block 9. Then, the fixing frame 10 is placed on the clamping block 9. At this time, the fixing frame 10 directly enters the fixing hole 29 in the insertion rod 26, thereby fixing the connection between the insert plate 11 and the clamping block 9. At the same time, when the insertion plate 11 is inserted into the clamping block 9, the connecting rod 24 on the rotating plate 13 installed on the insertion plate 11 directly enters the connecting hole 23 in the connecting block 12, and when the second motor 8 is driven, it drives the rotating plate 13 to rotate on the insertion plate 11, and the limiting plate 25 on the rotating plate 13 also rotates in the limiting groove 27 of the insertion plate 11. When the roller body 6 is placed on the insertion plate 11, the roller body 6 at this time contacts the positioning roller 17 installed on the positioning rod 16, and rotates smoothly on the insertion plate 11 as the second motor 8 rotates.

[0033] In summary, when in use, the laser device 5 is first debugged, the operator operates the control panel 18 on the main body 1, and then observes the display screen 19 to directly precisely control the laser engraving of the roller body 6, and then installs the roller body 6 in the middle of the clamping block 9. At this time, the two-way push rod 7 is in operation, pushing the clamping block 9 to slide in the second slide groove 21 of the main body 1. While the clamping block 9 slides, the balance plate 22 at the bottom of the clamping block 9 slides in the second slide groove 21, and the second motor 8 is driven, so that the size changing mechanism fixedly installed at the output end of the second motor 8 is operated, and as the electric push rod 7 is driven, the size changing mechanism fixedly installed at the output end of the second motor 8 is operated. The rod contracts, so that the extrusion pad 14 is in close contact with the two end surfaces of the roller body 6, so that the anti-slip strip 15 can be firmly in contact with the two end surfaces of the roller body 6, thereby completing the rotation of the roller body 6. Because the size specifications of the roller body 6 are different, and the fixed machine cannot meet the requirements of multiple sizes, the insert plate 11 can be replaced at this time, so as to pick up the insert plate 11, so that the insert rod 26 on the insert plate 11 directly enters the insert hole 28 of the clamping block 9, and then the fixing frame 10 is placed on the clamping block 9. At this time, the fixing frame 10 directly enters the fixing hole 29 in the insert rod 26, thereby fixing the insert plate 11. The connection between the insertion plate 11 and the clamping block 9, at the same time, when the insertion plate 11 is inserted into the clamping block 9, the connecting rod 24 on the rotating plate 13 installed on the insertion plate 11 directly enters the connecting hole 23 in the connecting block 12, and when the second motor 8 is driven, the rotating plate 13 is driven to rotate on the insertion plate 11, and the limiting plate 25 on the rotating plate 13 also rotates in the limiting groove 27 of the insertion plate 11. When the roller body 6 is placed on the insertion plate 11, the roller body 6 at this time contacts the positioning roller 17 installed on the positioning rod 16, and with the rotation of the second motor 8 It moves and rotates smoothly on the insert plate 11. When the roller body 6 rotates smoothly, the first motor 2 is driven to directly drive the screw 3 to rotate inside the main body 1, so that the sliding frame 4 slides in the first slide groove 20 of the main body 1, so that the laser equipment 5 fixedly mounted on the sliding frame 4 can perform laser engraving on the roller body 6 to complete the processing of the roller body 6 (when the laser equipment 5 is engraving, material may fall into the second slide groove 21 of the main body 1, affecting the operation of the clamping block 9. At this time, an iron plate of the same size as the roller body 6 can be placed on the main body 1 to complete the protection).
