Description

Technical Field

[0001] This utility model relates to the field of winding shaft technology, specifically to an automatic material winding shaft for a die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are 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. They utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing. Before operation, the working material needs to be fixed onto the die-cutting machine using a winding shaft or similar structure.

[0003] The existing material winding technology for die-cutting machines has the following problems: When the existing material winding machine is winding up the material, especially at the beginning of the winding process, the user needs to help fix the material on the winding machine. At the same time, the material may slip on the winding machine during the winding process, resulting in a decrease in the working efficiency of the winding machine.

[0004] Therefore, we propose an automatic material rewinding shaft for die-cutting machines. Utility Model Content

[0005] The purpose of this invention is to provide an automatic material rewinding shaft for a die-cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic material winding shaft for a die-cutting machine, comprising a roller, a clamping groove formed on the outer circumferential surface of the roller, connecting shafts fixedly installed at both ends of the roller, a transmission rod rotatably connected to the middle of the connecting shaft, a rotating column rotatably connected to one end of the transmission rod through both ends of the connecting shaft, a first bevel gear fixedly installed inside the connecting shaft in the middle of the rotating column, crank handle slots formed at both ends of the rotating column, a second bevel gear fixedly installed at one end of the transmission rod, the second bevel gear meshing with the first bevel gear, a rotating disk fixedly installed inside the roller at the other end of the transmission rod, a rotating shaft fixedly installed in the middle of the rotating disk, a deflection seat fixedly installed on the outer circumferential surface of the rotating shaft, a pull rod rotatably connected to the top of the deflection seat, a clamping plate rotatably connected inside the clamping groove, one side of the clamping plate rotatably connected to the other end of the pull rod, and a retaining spring located inside the clamping groove at the bottom of the clamping plate.

[0007] Optionally, fixed baffles are fixedly installed at both ends of the roller, the connecting shaft is fixedly installed through the middle of the fixed baffle, and the connecting shaft, transmission rod and roller are arranged coaxially.

[0008] Optionally, the rotating column is located on the part of the connecting shaft outside the roller, the rotating column is perpendicular to the transmission rod, and the crank slot is a polygonal groove.

[0009] Optionally, the rotating disk is rotatably connected to one end of the connecting shaft located inside the roller, and the two ends of the rotating shaft are fixedly installed with the opposite surfaces of the two rotating disks. The rotating shaft is coaxial with the roller.

[0010] Optionally, a rotating shaft is fixedly installed through the middle of the clamping plate, and the two ends of the rotating shaft are rotatably connected to the two sides inside the clamping groove. A clamping protrusion located on the other side is integrally provided on one side of the bottom of the clamping plate.

[0011] Optionally, the top of the clamping spring is fixedly installed with the bottom of the clamping plate, the clamping spring is located between the pull rod and the rotating shaft, and the bottom of the clamping spring is fixedly installed with the bottom of the clamping groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This die-cutting machine uses an automatic material winding shaft. It features clamping grooves and clamping plates. During operation, it is connected to the die-cutting machine via a connecting shaft. The crank handle is inserted into the crank handle slot, and turning the handle causes the rotating column to rotate. This, in turn, drives the transmission rod to rotate via the first and second bevel gears, which in turn rotates the rotating shaft. This causes the pull rod to deflect, pulling the clamping plate to rotate around the rotating shaft, opening one side of the clamping plate. The material to be wound is placed between the clamping plate and the roller. Releasing the crank handle causes the clamping plate to rotate in the opposite direction under the action of the retaining spring, clamping the material. This effectively fixes the material to the roller without requiring manual material securing, preventing material slippage during roller winding. Attached Figure Description

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.

[0021] Please see Figures 1 to 4This utility model provides an automatic material winding shaft for a die-cutting machine, including a roller 1. A clamping groove 16 is formed on the outer circumference of the roller 1. Connecting shafts 2 are fixedly installed at both ends of the roller 1. Fixed baffles 14 are fixedly installed at both ends of the roller 1. The connecting shaft 2 and the fixed baffles are fixedly installed through the middle. The connecting shaft 2, the transmission rod 4, and the roller 1 are arranged coaxially. The transmission rod 4 is rotatably connected to the middle of the connecting shaft 2. A rotating column 6 located at one end of the transmission rod 4 is rotatably connected through both ends of the connecting shaft 2. A first bevel gear 7 is fixedly installed inside the connecting shaft 2 in the middle of the rotating column 6. Crank handle slots 8 are formed at both ends of the rotating column 6. The rotating column 6 is located outside the roller 1 on the connecting shaft 2. The rotating column 6 is perpendicular to the transmission rod 4. The crank handle slot 8 is a polygonal groove. The rotating disk 15 is rotatably connected to one end of the connecting shaft 2 located inside the roller 1. The two ends of the rotating shaft 3 are fixedly installed to the opposite faces of the two rotating disks 15. The rotating shaft 3 is coaxial with the roller 1. A second bevel gear 5 is fixedly installed at one end of the transmission rod 4, and the second bevel gear 5 meshes with a first bevel gear 7. The other end of the transmission rod 4 is fixedly installed with the rotating disk 15 located inside the roller 1. The rotating shaft 3 is fixedly installed in the middle of the rotating disk 15. A deflection seat 17 is fixedly installed on the outer circumference of the rotating shaft 3. A pull rod 9 is rotatably connected to the top of the deflection seat 17. The inside of the clamping groove 16 is rotatably connected to... A clamping plate 10 is provided, with one side of the clamping plate 10 rotatably connected to the other end of the pull rod 9. A clamping spring 11 is located inside a clamping groove 16 at the bottom of the clamping plate 10. A rotating shaft 12 is fixedly installed through the middle of the clamping plate 10, with both ends of the rotating shaft 12 rotatably connected to the two sides inside the clamping groove 16. A clamping protrusion 13 is integrally provided on one side of the bottom of the clamping plate 10, located on the other side. The top of the clamping spring 11 is fixedly installed to the bottom of the clamping plate 10, and the clamping spring 11 is located between the pull rod 9 and the rotating shaft 12. The bottom of the clamping spring 11 is fixedly installed to the bottom of the clamping groove. The top arc surface of the clamping plate 10 is flush with the outer circumferential surface of the roller 1. The clamping groove 16 and clamping plate 10 are placed together. In use, they are installed with the die-cutting machine through the connecting shaft 2. The crank handle is inserted into the crank handle slot 8. Turning the crank handle causes the rotating column 6 to rotate, which in turn drives the transmission rod 4 to rotate through the first bevel gear 7 and the second bevel gear 5. This causes the rotating shaft 3 to rotate, causing the pull rod 9 to deflect and pull the clamping plate 10 to rotate around the rotating shaft 12. This causes one side of the clamping plate 10 to open, and the material to be wound is placed between the clamping plate 10 and the roller 1. Then, the crank handle is released, and the clamping plate 10 rotates in the opposite direction under the action of the retaining spring 11, clamping the material. This effectively fixes the material of the die-cutting machine onto the roller 1, which can effectively achieve the goal of not needing to fix the material manually and prevent the material from slipping when the roller 1 is winding.

[0022] Working principle:

[0023] In use, the die-cutting machine is installed via the connecting shaft 2. The crank handle is inserted into the crank handle slot 8, and turning the crank handle causes the rotating column 6 to rotate. This, in turn, drives the transmission rod 4 to rotate via the first bevel gear 7 and the second bevel gear 5. Consequently, the rotating shaft 3 rotates, causing the pull rod 9 to deflect and pull the clamping plate 10 to rotate around the rotating shaft 12. This causes one side of the clamping plate 10 to open, allowing the rolled material to be placed between the clamping plate 10 and the roller 1. Then, the crank handle is released, and under the action of the retaining spring 11, the clamping plate 10 rotates in the opposite direction, clamping the material. This effectively fixes the material to the roller 1 without the need for manual material fixing, preventing the material from slipping off the roller 1 during the rolling process.
