Description

Technical Field

[0001] This utility model relates to the field of auxiliary braking technology for automatic die-cutting machines, and in particular to an auxiliary braking device for automatic die-cutting machines. Background Technology

[0002] Automatic die-cutting machines are mainly used for precise cutting and shaping of various materials. They can cut materials such as paper, cardboard, plastic, leather, and rubber into specific shapes according to preset shapes, sizes, and patterns. They are widely used in packaging printing, electronics, automotive, clothing, labeling, and other industries to meet the production needs of different products, such as making packaging boxes, labels, insulating gaskets for electronic components, automotive interior parts, and clothing accessories.

[0003] However, in the existing technology, the inertia wheel of the existing automatic die-cutting machine has a large mass, and under the action of inertia, it cannot stop operating within a specified time. This results in the phenomenon of the machine slipping due to insufficient braking force of the original braking system when it stops, which affects the braking effect of the device and makes it unsatisfactory. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary braking device for automatic die-cutting machines. It aims to improve the problem that the inertia wheel of the existing automatic die-cutting machine has a large mass and cannot stop operating within a specified time under the action of inertia. This results in the phenomenon that the original braking system is not strong enough when stopping, causing the machine to slip due to insufficient braking force, which affects the braking effect of the device and results in poor performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base platform, a first rotating shaft on one side of the base platform, an inertia wheel fixedly connected to the outer surface of the first rotating shaft, a first support frame fixedly connected to one side of the base platform, one end of the first rotating shaft rotatably connected to the upper part of the first support frame, a second support frame fixedly connected to the lower part of one side of the base platform, a second rotating shaft rotatably connected to the upper end of the second support frame, a first transmission wheel fixedly connected to the outer surfaces of both the first and second rotating shafts, a first transmission belt connecting the two first transmission wheels, and an auxiliary braking mechanism provided above the first support frame.

The two first transmission wheels 11... The transmission is connected by a transmission belt 3. An auxiliary braking mechanism is set above the first support frame 9. The auxiliary braking mechanism includes a third support frame 20. One side of the third support frame 20 is fixedly connected to one side of the base platform 1. A cylinder 8 is fixedly connected to the upper end of the third support frame 20. A fixing block 7 is fixedly connected to the output end of the cylinder 8. A friction wheel 4 is fixedly connected to the outer surface of the first rotating shaft 5. A friction belt 6 is set on the outer surface of the friction wheel 4. One side of the fixing block 7 is fixedly connected to one end of the friction belt 6. The other end of the friction belt 6 is fixedly connected to the upper end of the first support frame 9.

[0035] In this embodiment, the base platform 1 is part of the structure of the automatic die-cutting machine. When the device needs to brake, the clutch in the braking mechanism 14 will disengage from the second transmission wheel 18 for emergency braking. At this time, the cylinder 8 on the side of the base platform 1 will retract its output end, causing its output end to pull one end of the friction belt 6 to move. The moving friction belt 6 will tighten under both ends of the cylinder 8, so that the friction belt 6 can be tightly attached to the outside of the friction wheel 4. At this time, the friction between the friction belt 6 and the friction wheel 4 will force the rotating friction wheel 4 to brake urgently, and after braking, force the first rotating shaft 5 to stop rotating. At this time, the inertia wheel 2 can obtain sufficient braking force and perform braking operation in a timely manner within the specified time. In this way, when the device needs to perform braking operation, its braking mechanism 14 can perform basic braking operation while its cylinder 8 pulls the friction belt 6 to adhere to the friction wheel 4, and perform auxiliary braking on the inertia wheel 2, so that the device can obtain sufficient braking force to complete braking within the specified time and avoid slippage.

[0036] Example 2, as Figures 1 to 3As shown, a fourth support frame 24 is fixedly connected to the upper side of one side of the base platform 1. A sliding mounting plate 25 is slidably connected to one side of the fourth support frame 24. A tensioning wheel 21 is rotatably connected to one side of the sliding mounting plate 25. Fasteners 26 are threaded around the sliding mounting plate 25. A fifth support frame 15 is provided on one side of the base platform 1. A third rotating shaft 19 is rotatably connected to the upper end of the fifth support frame 15. A coupling 10 is fixedly connected to one end of the third rotating shaft 19. One end of the second rotating shaft 13 is fixedly connected to one side of the coupling 10. A second transmission wheel 18 is fixedly connected to the outer surface of the third rotating shaft 19. A motor 17 is provided on one side of the fifth support frame 15. A third transmission wheel 22 is fixedly connected to the output end of the motor 17.

A brake mechanism 14 is provided on the outer surface of the third rotating shaft 19. A reinforcing rib 23 is fixedly connected to one side of the fifth support frame 15.

[0037] In this embodiment, a tensioning wheel 21 is provided above the first transmission belt 3. The tensioning wheel 21 is mounted on the sliding mounting plate 25. The tensioning wheel 21 can release the limitation on the sliding mounting plate 25 by tightening or loosening the fasteners 26 on the side of the sliding mounting plate 25. Then the sliding mounting plate 25 can slide on the side of the fourth support frame 24. At this time, the tensioning wheel 21 can be moved to adjust the tension of the tensioning wheel 21 on the first transmission belt 3. This method allows the device to be quickly adjusted according to the working requirements of the device during use, making the device more convenient to use.

[0038] Working principle: The motor 17 drives the third transmission wheel 22 to rotate, which in turn drives the second transmission wheel 18 fixed on the third shaft 19 to rotate via the second transmission belt 16. The third shaft 19 then rotates under the drive of the second transmission wheel 18, which in turn drives the second shaft 13 to rotate via the coupling 10. The second shaft 13 then drives one of the first transmission wheels 11 fixed on its outer surface to rotate, and under the action of the first transmission belt 3, drives the other first transmission wheel 11 to rotate. The first shaft, fixed to the other first transmission wheel 11... 5 can then rotate, thereby driving the inertia wheel 2 to rotate and providing power to the working parts inside the base 1. When the device needs to brake, the clutch in its braking mechanism 14 will disengage from the second transmission wheel 18 for emergency braking. At this time, the cylinder 8 on the side of the base 1 will retract its output end, causing its output end to pull one end of the friction belt 6 to move. The moving friction belt 6 will tighten under both ends of the cylinder 8, so that the friction belt 6 can be tightly attached to the outside of the friction wheel 4. At this time, the friction between the friction belt 6 and the friction wheel 4 will force it to... The rotating friction wheel 4 applies emergency braking, forcing the first rotating shaft 5 to stop rotating after braking. At this time, the inertia wheel 2 receives sufficient braking force, enabling timely braking within the specified time. This method allows the device to perform basic braking while its braking mechanism 14 pulls the friction band 6 against the friction wheel 4 via its cylinder 8, providing auxiliary braking to the inertia wheel 2. This ensures the device receives sufficient braking force to complete braking within the specified time, preventing slippage. A tensioning wheel 21 is installed above the transmission belt 3. The tensioning wheel 21 is mounted on the sliding mounting plate 25. The tensioning wheel 21 can be released from its limit by tightening or loosening the fasteners 26 on the side of the sliding mounting plate 25. Then the sliding mounting plate 25 can slide on the side of the fourth support frame 24. At this time, the tensioning wheel 21 can be moved to adjust the tension of the tensioning wheel 21 on the first transmission belt 3. This method allows the device to be quickly adjusted according to the working requirements of the device during use, making the device more convenient to use.
