Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, and in particular to a printing engraving machine with a lifting platform. Background Technology

[0002] Electronic engraving plate making is a modern plate making method that integrates modern mechanics, optics, electronics, and computers. It can quickly, accurately, and with high quality produce the required gravure plates and is one of the most widely used gravure plate making methods at present.

[0003] Currently, most engraving machines use a fixed flat worktable for their engraving platform. The surface of the worktable is usually designed with grid-like grooves or T-slots, and the workpiece is fixed by clamps, pressure plates or vacuum adsorption. This structure can provide a stable fixing effect for regular-shaped sheet workpieces, but for some complex-faced irregular workpieces, the fixed platform cannot flexibly adjust the tilt angle of the workpiece, which makes it inconvenient to effectively engrave some complex curved surfaces or sides.

[0037] 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.

[0038] This utility model provides, for example Figure 1-4The engraving machine for printing with a lifting platform shown includes a worktable 1, a support platform 3, an adjustment mechanism 4, and a lifting mechanism 5. The engraving machine body 2 is slidably mounted on the worktable 1. The support platform 3 is located inside the worktable 1. The adjustment mechanism 4 is located on the support platform 3 and is used to adjust the angle of the support platform 3. The lifting mechanism 5 is located inside the worktable 1 and is used to adjust the height of the support platform 3. The adjustment mechanism 4 can adjust the tilt angle of the support platform 3 so that the complex curved surface or side of the irregular workpiece is always in the best engraving position without repeated disassembly and adjustment, which greatly improves the processing efficiency. The lifting mechanism 5 can finely adjust the height of the support platform 3 to ensure that workpieces of different thicknesses can be firmly fixed. It retains the stability of the traditional flat worktable 1 and gives it flexible turning capability, making it easy to use.

[0039] Specifically, the adjustment mechanism 4 includes a support frame 41, a rotating rod 42, a driving rod 43, a synchronous pulley 44, a synchronous belt 45, a pressing rod 46, a positioning frame 47, a positioning plate 48, and a compression spring 49. The support frame 41 is symmetrically arranged on both sides of the worktable 1. The rotating rod 42 is fixedly connected to both sides of the support platform 3, and the rotating rod 42 is rotatably inserted and connected to the support frame 41. An adjustment groove is opened on the outer wall of one of the support frames 41, and the driving rod 43 is rotatably arranged inside the adjustment groove. The synchronous pulley 44 is fixedly inserted and connected to the rotating rod 42 and the driving rod 43 respectively. The synchronous belt 45 is arranged between the synchronous pulleys 44. The extrusion rod 46 is slidably inserted into the inner cavity of the drive rod 43; the positioning frame 47 is fixedly connected to the outer wall of one of the support frames 41; the positioning plate 48 is fixedly connected to one end of the extrusion rod 46, and the inner wall of the positioning frame 47 is provided with a positioning groove. The positioning plate 48 is slidably inserted into the inner cavity of the positioning groove, and the cross-section of the positioning plate 48 is polygonal; one end of the compression spring 49 is fixedly connected to the positioning plate 48, and the other end of the compression spring 49 is fixedly connected to the drive rod 43. The other end of the extrusion rod 46 is fixedly connected to the pull plate 410. The outer wall of the worktable 1 is provided with a pull groove for the pull plate 410 to slide. By rotating the drive rod 43, the synchronous wheel 44 and the synchronous belt 45 are driven, so that the rotating rods 42 on both sides rotate synchronously, thereby adjusting the angle of the bearing platform 3. The extrusion rod 46 pushes the positioning plate 48 into the polygonal positioning groove of the positioning frame 47 through the elastic force of the compression spring 49 to achieve angle locking. Pulling the pull plate 410 causes the extrusion rod 46 to retract, and the positioning plate 48 to disengage from the positioning groove, so that the angle can be freely adjusted.

[0040] Specifically, the lifting mechanism 5 includes a bidirectional screw 51, a motor 52, a moving block 53, a lifting platform 54, a rotating seat 55, and a connecting rod 56. The end of the bidirectional screw 51 is rotatably connected to the inner wall of the worktable 1. The motor 52 is fixedly installed on the outside of the worktable 1, and the output end of the motor 52 is connected to the end of the bidirectional screw 51 for transmission. The moving block 53 is symmetrically arranged inside the worktable 1, and the moving block 53 and the bidirectional screw 51 form a screw drive. The lifting platform 54 is slidably arranged inside the worktable 1, and the support frame 41 is fixedly connected to the top of the lifting platform 54. The rotating seat 55 is fixedly connected to the top of the moving block 53 and the bottom of the lifting platform 54 respectively. The end of the connecting rod 56 is connected to the inner wall of the worktable 1. The rotating seat 55 is rotatably connected, and sliders 57 are fixedly connected to both sides of the lifting platform 54. Slide grooves for sliding of sliders 57 are opened on both sides of the inner wall of the worktable 1. The motor 52 drives the bidirectional screw 51 to rotate, which drives the moving blocks 53 on both sides to move synchronously in opposite directions. The moving blocks 53 push the lifting platform 54 to move vertically through the rotating seat 55 and the connecting rod 56. The sliders 57 are guided along the slide grooves to ensure smooth lifting. The lifting of the lifting platform 54 drives the support frame 41 and the entire adjustment mechanism 4 to realize the overall adjustment of the height of the bearing platform 3. With the help of the adjustment mechanism 4, the height and angle of the engraving platform can be freely adjusted, solving the problem of processing irregular parts, while taking into account efficiency, accuracy and reliability.
