Description

Technical Field

[0001] This utility model relates to the field of elastic band cutting technology, and in particular to an elastic band cutting device. Background Technology

[0002] Elastic bands work on the principle of high elasticity, allowing them to deform under tension or external force to adapt to various stresses and working conditions, and quickly return to their original shape after the force is removed. This property enables elastic bands to play a crucial role in many fields, including power transmission, torque transmission, maintaining fastness, shock absorption, and cushioning. For example, in industrial equipment, elastic bands are often used to connect components, providing shock absorption and extending equipment lifespan. In some applications, especially those requiring large-area coverage, the length of a single elastic band may be insufficient, necessitating the splicing of two or more bands to meet length requirements. In such cases, ensuring precise and flat splices and clean cut edges is crucial, thus requiring an elastic band cutting device.

[0003] In existing technologies, after the elastic band is cut, the take-up drum is fixed in one piece, making it difficult to replace. This causes many inconveniences in practical applications. After a roll of elastic band is cut, if the take-up drum cannot be replaced quickly, the operator must manually disassemble or clean the rolled elastic band. This process is both time-consuming and labor-intensive, leading to increased equipment downtime and affecting production efficiency. Especially in scenarios requiring continuous and high-speed production, the inability to quickly replace the take-up drum will severely limit production capacity and increase the complexity of operation and labor costs.

Alternatively, the winding block 6 is fixedly connected to a locking block 15 in the middle. The outer wall of the rotating rod 11 is provided with a locking groove 14, a sliding groove 24 and an adjusting groove 13. The locking groove 14 and the locking block 15 are engaged with each other. The locking groove 14 and the locking block 15 can easily engage and fix the rotating rod 11 and the winding block 6, and at the same time, it can easily disassemble and replace the winding block 6, thereby reducing the labor intensity of the workers and improving work efficiency. The support plate 5 is provided with a reset component on the side away from the motor 10. The reset component is used to squeeze the winding block 6.

[0033] Reference Figure 3 and Figure 4The reset assembly includes a spring rod 16, which is fixedly connected to one side of the support plate 5. The support plate 5 can easily support the spring rod 16. The end of the spring rod 16 away from the support plate 5 is fixedly connected to a pressing plate 12. The spring rod 16 can easily drive the pressing plate 12 to move to one side, thereby pressing and limiting the winding block 6, so that the winding block 6 and the rotating rod 11 are locked together. The cutting assembly includes a connecting rod 17, which is rotatably connected to the middle of the fixed frame 7. The bottom of the connecting rod 17 is fixedly connected to a cylinder 18, which can easily support the cylinder 18, making the cylinder 18 more stable. At the same time, when the connecting rod 17 rotates, it will drive the cylinder 18 to rotate simultaneously. The output end of the cylinder 18 is fixedly connected to a cutter 9. When the cylinder 18 works, it will drive the cutter 9 to move downward, thereby facilitating the cutting and adjustment of the elastic band. The top of the fixed frame 7 is provided with an adjustment assembly, which is used to drive the cylinder 18 to rotate.

[0034] Reference Figure 4 The adjusting component includes a gear 19, which is fixedly connected to the top of the connecting rod 17. When the gear 19 rotates, it can easily drive the connecting rod 17 to rotate simultaneously. A rack 20 is slidably connected to the top of the fixed frame 7. The rack 20 and the gear 19 mesh with each other. When the rack 20 moves, it can easily drive the gear 19 to rotate. The top of the fixed frame 7 is provided with a driving component, which is used to drive the rack 20 to move. The driving component includes a support frame 22, which is fixedly connected to the top of the fixed frame 7. An electric push rod 23 is fixedly connected to the middle of the support frame 22. One end of the rack 20 is fixedly connected to the output end of the electric push rod 23. The support frame 22 can easily support and fix the electric push rod 23, making the electric push rod 23 more stable when working. When the electric push rod 23 works, it can easily drive the rack 20 to move.

The outer periphery of the connecting rod 17 is fixedly connected to a limiting ring 21. There are two limiting rings 21. One limiting ring 21 is slidably connected to the top of the fixed frame 7, and the other limiting ring 21 is slidably connected to the bottom of the fixed frame 7. The two limiting rings 21 can conveniently limit the connecting rod 17, thereby preventing the connecting rod 17 from shifting when rotating. The bottom of the operating table 1 is fixedly connected to a support column 2, and the top of the operating table 1 is fixedly connected to a control panel 3. The support column 2 can conveniently support and fix the operating table 1, while the control panel 3 can conveniently allow the operator to control the entire device.

[0036] Working principle: When the take-up block 6 needs to be replaced, the compression plate 12 is squeezed by pressing one side of the take-up block 6, which causes the spring rod 16 to retract. When the take-up block 6 moves, the locking block 15 in the middle of the take-up block 6 will disengage from the locking groove 14. After the locking block 15 disengages from the locking groove 14, the take-up block 6 is rotated so that the locking block 15 slides out through the slide groove 24, thereby allowing the take-up block 6 to be replaced quickly.

[0037] When the angle of the cutter 9 needs to be adjusted, the electric push rod 23 is activated. When the electric push rod 23 is working, it will drive the rack 20 to move. When the rack 20 moves, it will drive the gear 19 to rotate. When the gear 19 rotates, it will drive the cylinder 18 to rotate simultaneously through the connecting rod 17. When the cylinder 18 rotates, it will drive the cutter 9 to rotate, thereby adjusting the cutting angle of the elastic band.
