[0023] Working principle and advantages of the present invention: When the continuous shearing device for producing aircraft gaskets is used, the working process is as follows: like Figure 6 As shown, the raw material roll to be cut is installed on the unwinding drum 36, one end of the raw material passes under the pressure strip 38 and is wound on the winding drum 37. The initial state is as shown in FIG. Figure 1As shown, at this time, the lifting cylinder 3 contracts so that the lifting plate 4 is in the highest position, and the sliding sleeve 6 is at the upper end of the vertical groove 33. After the raw material roll is installed, the lifting cylinder 3 is started to work, so that the lifting cylinder 3 pushes the lifting plate 4 to move downward. Since the upper end depth of the inclined groove 34 is greater than the upper end depth of the vertical groove 33, when the lifting plate 4 moves downward, the sliding sleeve 6 moves downward along the inclined groove 34, and under the interaction between the sliding sleeve 6 and the inclined groove 34, the groove roller 14 drives the turntable 11 through the vertical rod 13. Figure 4 The sliding sleeve 6 rotates counterclockwise in the middle, and when the sliding sleeve 6 enters the middle of the next vertical groove 33, it moves down along the vertical groove 33, and at this time the groove roller 14 and the turntable 11 do not rotate, so that the lifting plate 4 drives the lower pressing cylinder 7 to move down and press the ring plate 25, so that the ring plate 25 drives the cutting outer cylinder 12 and the cutting inner cylinder 24 to cut the raw materials on the cutting table 15, and compresses the spring 22, so that the spring 22 obtains a restoring force. When the sliding sleeve 6 moves down to the lower end of the vertical groove 33, the lifting plate 4 drives the lower pressing cylinder 7 to move down and press the ring plate 25, so that the ring plate 25 drives the cutting outer cylinder 12 and the cutting inner cylinder 24 to cut the raw materials on the cutting table 15, and compresses the spring 22, so that the spring 22 obtains a restoring force. The cylinder 3 drives the lifting plate 4 to move up and reset, and during the resetting of the lifting plate 4, the groove roller 14 and the turntable 11 do not rotate. Since the middle depth of the vertical groove 33 is greater than the lower end depth of the inclined groove 34, it can move to the uppermost end along the vertical groove 33 when resetting. After the lifting plate 4 is reset, the lower pressure cylinder 7 does not apply downward pressure to the ring plate 25. Under the action of the restoring force of the spring 22, the ring plate 25 drives the cutting outer cylinder 12 and the cutting inner cylinder 24 to move up and reset, thereby completing the cutting of the gasket.

[0024] like Figure 1 and Figure 2 As shown, while the turntable 11 rotates, the shaft 19 is driven to rotate through the bevel gear set 20, so that the shaft 19 drives the winding drum 37 to rotate through the pulley assembly 21 to wind the raw material, and the unwinding drum 36 unwinds the raw material, thereby realizing the unwinding of the raw material and the winding of the cut waste.

[0025] As described above, in the process of the lifting plate 4 driving the lower pressure rod 9 to move downward, the lower pressure rod 9 presses down on the circular plate 31, so that the circular plate 31 compresses the spring three 32, and the spring three 32 obtains a restoring force. When the circular plate 31 moves downward, it drives the material return rod two 30 to push out the ring core in the cut inner cylinder 24 and drop it into the ring core collection box 16 below. In the process of the lifting plate 4 resetting, it drives the lower pressure rod 9 away from the circular plate 31, so that under the action of the restoring force of the spring three 32, the circular plate 31 drives the material return rod two 30 to reset.

[0026] In the process of the lifting plate 4 driving the pressing cylinder 28 to move downward, the pressing cylinder 28 presses down the ring plate 26, so that the ring plate 2 compresses the spring 28 and the spring 28 obtains a restoring force. When the ring plate 26 moves downward, it drives the material return rod 1 27 to push out the gasket between the cutting outer cylinder 12 and the cutting inner cylinder 24, and drops it into the gasket collection box 17 below. In the process of the lifting plate 4 resetting, it drives the pressing cylinder 28 away from the ring plate 26, so that under the action of the restoring force of the spring 28, the ring plate 26 drives the material return rod 1 27 to reset, thereby realizing the synchronous material return and separate collection of the gasket and the ring core.

[0027] The entire device can simultaneously cut the raw materials and withdraw the gaskets and ring cores, and can automatically discharge the raw materials and reel in the waste materials, saving time and labor and greatly improving the production efficiency of gaskets.

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
