Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a frame for a rotary die-cutting machine. Background Technology

[0002] A die-cutting machine, also known as a die-cutting machine, cutting machine, or CNC punching machine, is mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. The die-cutting machine uses steel blades, metal molds, and steel wire (or a template carved from a steel plate) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. It is an important piece of equipment for post-printing packaging processing. When processing new materials such as adhesive tapes (brown adhesive, insulating sheets, protective films), a rotary die-cutting machine is required, and these machines are typically mounted on a frame.

[0003] However, the frames for rotary die-cutting machines in related technologies still have shortcomings. It is inconvenient to adjust the distance between the die-cutting roller and the support roller according to the thickness of the material, which reduces the scope of use. Furthermore, it is inconvenient to easily disassemble and assemble the die-cutting roller according to the needs of die-cutting and creasing, which makes it inconvenient to easily replace die-cutting rollers of different specifications and thus makes it inconvenient to die-cut and creasing tape into different shapes. Therefore, we propose a frame for a rotary die-cutting machine to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a frame for a rotary die-cutting machine, which allows the spacing between the die-cutting roller and the support roller to be adjusted according to the thickness of the material, thereby increasing the range of applications. It also allows for easy disassembly and assembly of the die-cutting roller according to the needs of die-cutting and creasing, so as to facilitate the replacement of die-cutting rollers of different specifications and thus make it easy to creasing tape into different shapes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a frame for a rotary die-cutting machine, comprising a base and a frame fixedly connected to the top of the base, support rollers rotatably connected to the inner walls on both sides of the frame, two sliders provided on the frame, hollow shafts rotatably sleeved inside the sliders, a same molding roller detachably connected between the two hollow shafts, a convenient disassembly and assembly mechanism provided between the molding roller, the two hollow shafts and the frame, a height adjustment mechanism provided between the frame and the two sliders, two guide rollers rotatably connected to the inner walls on both sides of the frame, and a support roller located between the two guide rollers.

[0006] A further feature of this invention is that: both sides of the frame are fixedly connected to lower bearings, the support roller is fixedly sleeved in the inner rings of the two lower bearings, the slider is fixedly sleeved with an upper bearing, and the two hollow shafts are respectively fixedly sleeved in the inner rings of the corresponding upper bearings.

[0007] By adopting the above technical solution, the hollow shaft and support roller can be supported, making its rotation more stable and smooth.

[0008] A further feature of this invention is that the height adjustment mechanism includes a bidirectional motor fixedly connected to the top of the frame, a rectangular opening on one side of the frame, and two threaded cylinders rotatably connected to the top of the frame. Drive shafts are fixedly connected to the output shafts at both ends of the bidirectional motor. A driving bevel gear is fixedly connected to one end of each of the two drive shafts. A driven bevel gear is fixedly connected to the top of each of the two threaded cylinders. The two driving bevel gears mesh with their corresponding driven bevel gears. A lifting screw is threaded into each of the two threaded cylinders, and the bottom ends of the two lifting screws are fixedly connected to the top of their respective sliders.

[0009] By adopting the above technical solution, the two drive shafts and two active bevel gears are driven to rotate synchronously by a bidirectional motor. The two active bevel gears drive the two driven bevel gears and the threaded cylinder to rotate synchronously. The two threaded cylinders drive the lifting screw and two sliders to rise and fall, thereby driving the molding roller to rise and fall, so as to adjust the distance between the support roller and the molding roller, and at the same time adjust the molding force, thus improving the versatility of the device.

[0010] A further feature of this invention is that a fixed base is fixedly connected to the top of the frame, and the bidirectional motor is fixedly connected to the top of the fixed base.

[0011] By adopting the above technical solution, it is convenient to support and fix the bidirectional motor, thereby improving its stability during operation.

[0012] A further feature of this invention is that two sliders are slidably fitted into corresponding rectangular openings, and two threaded cylinders are rotatably connected to the top of the frame via bearings.

[0013] By adopting the above technical solution, the slider can be guided and the threaded cylinder can be supported, making its rotation more stable.

[0014] The present invention is further configured as follows: the convenient disassembly and assembly mechanism includes a connecting shaft slidably sleeved in a hollow shaft, a slide rod slidably sleeved in a slider, a return spring fixedly connected to one side of the slider, the return spring and one end of the slide rod being fixedly connected to the same moving plate, the connecting shaft being rotatably sleeved in the moving plate, one end of the connecting shaft being fixedly connected to a square block, both ends of the molding roller having square grooves, the two square blocks being movably engaged in the corresponding square grooves, the top of the moving plate being fixedly connected to a triangular plate, two extrusion blocks being fixedly connected to the top inner wall of the frame, the extrusion blocks cooperating with the triangular plate, one end of the slide rod being fixedly connected to a limiting plate, the limiting plate being movably abutting against the outside of the slider, one side of the limiting plate being threadedly connected to a screw, the outside of the slider having a threaded groove, the screw being threadedly connected in the threaded groove, the connecting shaft being rotatably sleeved in the moving plate via a bearing, and the return spring being sleeved on the outside of the slide rod.

[0015] By adopting the above technical solution, loosening the screws allows them to disengage from the threaded grooves of the slider without locking the limiting plate, thus preventing the sliding rod and the moving plate from locking. At this point, the bidirectional motor drives the two sliders and the molding rollers to move upwards, creating a certain distance between the molding rollers and the support rollers for easy disassembly and assembly. Simultaneously, the sliders drive the sliding rod, the moving plate, and the triangular plates to move upwards. When the triangular plates abut against the inclined surface of the extrusion block, they are squeezed by the extrusion block, causing the two triangular plates to move outwards automatically, thus driving the moving plate and the connecting shaft. As the square blocks move outward and disengage from the square slots, the molding roller is no longer fixed. At this point, the molding roller can be removed for replacement. Pull the limiting plate outward and place the new molding roller between the two square blocks. Release the limiting plate. Under the elastic force of the return spring, the two moving plates, connecting shaft, and square blocks approach each other and engage in the corresponding square slots. This fixes the molding roller between the two hollow shafts. Finally, tighten the screws to lock the limiting plate in the rotating threaded groove, improving the stability of the connection between the hollow shaft and the molding roller.

[0016] The beneficial effects of this utility model are: 1. This utility model uses a bidirectional motor to drive two drive shafts and two active bevel gears to rotate synchronously. The two active bevel gears drive two driven bevel gears and threaded cylinders to rotate synchronously. The two threaded cylinders drive the lifting screw and two sliders to rise and fall, thereby driving the molding roller to rise and fall, so as to adjust the distance between the support roller and the molding roller, and at the same time adjust the molding force, improving the versatility of the device.

[0017] 2. In this utility model, loosening the screw allows it to disengage from the threaded groove of the slider without locking the limiting plate, and consequently, without locking the sliding rod and the moving plate. At this point, the bidirectional motor drives the two sliders and the molding roller to move upward, creating a certain distance between the molding roller and the support roller, facilitating disassembly and assembly. Simultaneously, the slider drives the sliding rod, the moving plate, and the triangular plate to move upward. When the triangular plate abuts against the inclined surface of the extrusion block, it will be squeezed by the extrusion block, causing the two triangular plates to move outward automatically, which in turn drives the moving plate, the connecting shaft, and the square block to move outward and disengage from the square groove, thus preventing the molding roller from being fixed. At this point, the molding roller can be removed.

[0018] 3. When installing this utility model, pull the limiting plate outward to place the new molding roller between the two square blocks. Release the limiting plate. At this time, under the elastic force of the return spring, the two moving plates, connecting shaft and square blocks approach each other and are engaged in the corresponding square grooves. This fixes the molding roller between the two hollow shafts. Finally, tighten the screws to lock the limiting plate in the rotating threaded groove, thereby improving the stability of the connection between the hollow shaft and the molding roller.

The same molding roller 9 is detachably connected between the two hollow shafts 4. The molding roller 9 is provided with different concave and convex shapes so as to press out different shapes. A convenient disassembly and assembly mechanism 7 is provided between the molding roller 9, the two hollow shafts 4 and the frame 2. A height adjustment mechanism 6 is provided between the frame 2 and the two sliders 69. Two guide rollers 3 are rotatably connected to the inner walls on both sides of the frame 2. The support rollers 5 are located between the two guide rollers 3.

[0024] Specifically, both sides of the frame 2 are fixedly connected to lower bearings 8, and the support rollers 5 are fixedly sleeved inside the inner rings of the two lower bearings 8.

[0025] Specifically, the upper bearing 10 is fixedly sleeved inside the slider 69, and the two hollow shafts 4 are respectively fixedly sleeved inside the inner ring of the corresponding upper bearing 10.

[0026] Specifically, the height adjustment mechanism 6 includes a bidirectional motor 62 fixedly connected to the top of the frame 2, a rectangular opening 67 on one side of the frame 2, and two threaded cylinders 66 rotatably connected to the top of the frame 2. Drive shafts 63 are fixedly connected to the output shafts at both ends of the bidirectional motor 62. One end of each drive shaft 63 is fixedly connected to a drive bevel gear 64. The top ends of each threaded cylinder 66 are fixedly connected to a driven bevel gear 65. The two drive bevel gears 64 mesh with the corresponding driven bevel gears 65. Lifting screws 68 are threadedly fitted inside each of the two threaded cylinders 66. The bottom ends of the two lifting screws 68 are fixedly connected to the top of the corresponding sliders 69.

[0027] Specifically, a fixed base 61 is fixedly connected to the top of the frame 2, and a bidirectional motor 62 is fixedly connected to the top of the fixed base 61.

[0028] Specifically, the two sliders 69 are slidably fitted into the corresponding rectangular openings 67.

[0029] Specifically, the two threaded cylinders 66 are rotatably connected to the top of the frame 2 via bearings.

[0030] Specifically, the convenient disassembly and assembly mechanism 7 includes a connecting shaft 74 slidably sleeved in the hollow shaft 4, a slide rod 70 slidably sleeved in the slider 69, a return spring 77 fixedly connected to one side of the slider 69, a moving plate 75 fixedly connected to one end of the return spring 77 and the slide rod 70, the connecting shaft 74 rotatably sleeved in the moving plate 75, a square block 79 fixedly connected to one end of the connecting shaft 74, square grooves 78 opened at both ends of the molding roller 9, two square blocks 79 respectively movably engaging in the corresponding square grooves 78, a triangular plate 76 fixedly connected to the top of the moving plate 75, and two extrusion blocks 73 fixedly connected to the top inner wall of the frame 2, the extrusion blocks 73 cooperating with the triangular plate 76.

[0031] Specifically, one end of the slide rod 70 is fixedly connected to a limiting plate 72, which movably abuts against the outside of the slider 69. A screw 71 is threadedly connected to one side of the limiting plate 72, and a threaded groove is opened on the outside of the slider 69, with the screw 71 threadedly connected in the threaded groove.

[0032] Specifically, the connecting shaft 74 is rotatably mounted inside the movable plate 75 via a bearing, and the return spring 77 is sleeved on the outside of the slide rod 70.

[0033] In this invention, the guide roller 3 guides the tape, and an external traction device pulls the tape. The support roller 5 and the molding roller 9 work together to perform die-cutting and creasing on the tape. A bidirectional motor 62 drives two drive shafts 63 and two active bevel gears 64 to rotate synchronously. The two active bevel gears 64 drive two driven bevel gears 65 and threaded cylinders 66 to rotate synchronously. The two threaded cylinders 66 drive the lifting screw 68 and two sliders 69 to rise and fall, thereby driving the molding roller 9 to rise and fall, adjusting the distance between the support roller 5 and the molding roller 9, and simultaneously adjusting the molding force, improving the versatility of the device. The bidirectional motor 62 can be connected to an external controller for precise control. When different shapes need to be die-cut and creasing, first loosen the screw 71 so that it disengages from the threaded groove of the slider 69 and does not lock the limit plate 72, thus preventing the slide rod 70 from being locked. Locked to the movable plate 75, the bidirectional motor 62 drives the two sliders 69 and the molding roller 9 to move upward, so that the molding roller 9 is at a certain distance from the support roller 5, which is convenient for personnel to disassemble and assemble. At the same time, the slider 69 drives the slide rod 70, the movable plate 75 and the triangular plate 76 to move upward. When the triangular plate 76 abuts against the inclined surface of the extrusion block 73, it will be squeezed by the extrusion block 73, so that the two triangular plates 76 automatically move outward and drive the movable plate 75, the connecting shaft 74 and the square block 79 to move outward and disengage from the square groove 78, thus not fixing the molding roller 9. At this time, the molding roller 9 can be taken out for replacement. Pull the limiting plate 72 outward and place the new molding roller 9 between the two square blocks 79. Release the limiting plate 72. At this time, under the elastic force of the return spring 77, the two movable plates 75, the connecting shaft 74 and the square block 79 approach each other and are locked in the corresponding square groove 78, thus fixing the molding roller 9 between the two hollow shafts 4.
