Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-cutting circular knives, and in particular to a movable ejector ring circular knife. Background Art
[0002] A circular knife, also known as a rotary die-cutter, is a type of die-cutting tool that has a faster die-cutting speed than a flat die-cutting knife. It can achieve more precision, produce complex products, and has higher efficiency. Since the drum of a rotary die-cutter rotates continuously when it is working, its production efficiency is the highest among all types of die-cutting machines. However, the die-cutting plate has to be bent into a curved surface, and plate making is more troublesome and costly. It also has certain technical difficulties. Therefore, a rotary die-cutter is often used for mass production.
[0003] However, in the existing circular knife die-cutting machines, the position of the circular knife is fixed. When the width of the raw materials is different or the requirements for cutting the raw materials are different, the position of the circular knife cannot be moved and adjusted, which reduces the universality of the equipment. Utility Model Content

Both ends of the knife shaft 2 are rotatably connected to the rotation holes. A mounting block 5 is fixedly connected to the top of the bottom plate 1. A motor 6 is installed on the top of the mounting block 5. The output end of the motor 6 is connected to the knife shaft 2. A plurality of uniformly distributed transverse grooves are provided on the knife shaft 2. A fixing rod 7 is fixedly connected to the inside of the transverse groove. A plurality of movable frames 8 are sleeved on the fixing rod 7. A threaded hole is provided at one end of the movable frame 8.

One end of the threaded rod 9 A pressing block 10 is connected to the fixed rod 7, and one end of the threaded rod 9 passes through a transverse groove and is connected to a circular knife 11. When the equipment has different processing requirements for raw materials of different widths or the equipment has different processing requirements for raw materials, the rotating circular knife 11 drives the threaded rod 9 to rotate, so that the threaded rod 9 drives one end of the pressing block 10 to separate from the fixed rod 7. At this time, the circular knife 11, the threaded rod 9 and the moving frame 8 can be pulled to move along the fixed rod 7. When the circular knife 11 moves to the specified position, the rotating circular knife 11 drives the threaded rod 9 to rotate, thereby driving one end of the pressing block 10 to be close to the fixed rod 7, thereby fixing the position of the circular knife 11, so as to facilitate personnel to move and adjust the position of the circular knife 11, thereby improving the universality of the equipment.
[0028] Reference Figure 3 and Figure 4 A spring 12 is connected to the inside of the circular knife 11, and one end of the spring 12 is connected to a pin 13. When the equipment is running, the circular knife 11 cooperates with the pressure roller 4 to die-cut the raw material. The die-cut waste presses the pin 13 to retract, so that the waste enters the inside of the circular knife 11. When the circular knife 11 is separated from the raw material, the spring 12 pushes the pin 13 to reset. At this time, the pin 13 pushes the waste away from the circular knife 11, so as to achieve clean waste discharge during the die-cutting process.
[0029] Reference Figure 3 and Figure 4 A first limiting member 14 is fixedly connected to the inner wall of the circular knife 11, and the ejector pin 13 is slidably connected to the first limiting member 14.

At this time, the circular knife 11, the threaded rod 9 and the movable frame 8 can be pulled to move along the fixed rod 7. When the circular knife 11 moves to the specified position, the rotating circular knife 11 drives the threaded rod 9 to rotate, thereby driving one end of the pressing block 10 to be close to the fixed rod 7, thereby fixing the position of the circular knife 11, so as to facilitate personnel to move and adjust the position of the circular knife 11, thereby improving the universality of the equipment. When the equipment is running, the circular knife 11 cooperates with the pressure roller 4 to die-cut the raw material, and the die-cut waste presses the ejector pin 13 to retreat. , so that the waste enters the inside of the circular knife 11. When the circular knife 11 is separated from the raw material, the spring 12 pushes the ejector pin 13 to reset. At this time, the ejector pin 13 pushes the waste to separate from the circular knife 11, so as to achieve clean waste discharge during the die-cutting process. The first limiting member 14 is used to limit the ejector pin 13 to prevent the ejector pin 13 from deflecting during the working process, resulting in unclean discharge, so as to achieve the purpose of improving the stability of the equipment. The limiting slide groove 15 cooperates with the second limiting member 16 to limit the threaded rod 9 to prevent the threaded rod 9 from deflecting, so as to limit the circular knife 11 to prevent the circular knife 11 from deflecting, so as to maintain the die-cutting effect of the circular knife 11 on the raw material, so as to achieve the purpose of improving the stability of the equipment.
