The guide members can adopt the precision straight line guide pair, the straight line guide pair is composed of the guide rail 407 and the sliding block 408. On the inlet side of the shearing mechanism 400, the guide rail 407 is connected with the lower cutter seat 403, the sliding block 408 should be installed on the upper cutter seat 404; on the outlet side of the shearing mechanism 400, the guide rail 407 is connected with the upper cutter seat 404, the sliding block 408 should be installed on the lower cutter seat 403.

[0037] The prior art cannot stably perform continuous operation for shearing of the very thin strip, and the continuous operation has stop or delay, and the shearing quality of the strip is not uniform during the continuous operation. The application drives the synchronous shaft 301 to rotate through the driving mechanism 100, drives the lower knife shaft 401 to rotate through the transmission mechanism 300, and then drives the upper knife shaft 402 to rotate, so that the lower knife shaft 401 and the upper knife shaft 402 generate circular motion, and the lower knife shaft 401 and the upper knife shaft 402 can periodically and synchronously approach or separate each other due to the opposite motion directions; the lower knife seat 403 is rotationally connected with the lower knife shaft 401, the upper knife seat 404 is rotationally connected with the upper knife shaft 402, the lower blade 405 is connected with the lower knife seat 403, and the upper blade 406 is connected with the upper knife seat 404, so that the upper knife seat 404 and the lower knife seat 403 can approach or separate each other; and the guide installed between the lower knife seat 403 and the upper knife seat 404 can limit the operation of the upper knife seat 404 and the lower knife seat 403, so that the upper knife seat 404 and the lower knife seat 403 can only move relatively in the vertical direction, that is, the upper blade 406 and the lower blade 405 can only move relatively in the vertical direction to approach or separate each other. In this way, the two blades can periodically shear the metal very thin strip, complete the stable and reliable breaking of the metal very thin strip in motion, cutting of the welding seam, cutting of the sample and cutting of the waste treatment, realize continuous operation and stable production, and effectively improve the production efficiency.

[0038] The simple and compact shearing mechanism 400 has high transmission rigidity, low rotational inertia and good dynamic performance. The lower blade seat 403 and the upper blade seat 404 adopt a beam structure with an axle hole. The lower blade shaft 401 and the upper blade shaft 402 pass through the blade seats of the beam structure and are supported by precise rolling bearings at both ends. In an optional embodiment, the shearing mechanism 400 further comprises a lower blade seat 403, an upper blade seat 404 and a guide. The lower blade seat 403 is rotationally connected with the lower blade shaft 401, the upper blade seat 404 is rotationally connected with the upper blade shaft 402, and the guide is connected with the lower blade seat 403 and the upper blade seat 404. The guide limits the movement of the lower blade seat 403 and the upper blade seat 404 in the vertical direction. In an optional embodiment, the shearing mechanism 400 further comprises a blade seat bearing 409. The blade seat bearing 409 is embedded at both ends of the lower blade seat 403 and the upper blade seat 404. Thus, the lower blade shaft 401 and the upper blade shaft 402 are matched and connected to the corresponding blade seat bearings 409 at the end portions. When the lower blade shaft 401 and the upper blade shaft 402 rotate, the lower blade seat 403 and the upper blade seat 404 can rotate relative to each other. Under the constraint of the guide, the lower blade seat 403 and the upper blade seat 404 can maintain relative close or separate movement in the vertical direction. The lower blade 405 is connected to the upper part of the lower blade seat 403, and the upper blade 406 is connected to the lower part of the upper blade seat 404. The movement of the lower blade seat 403 and the upper blade seat 404 drives the movement of the lower blade 405 and the upper blade 406. During the shearing process, the lower blade 405 and the upper blade 406 always maintain perpendicularity with the strip and constant blade side gap. The lower blade 405 and the upper blade 406 synchronously move close to and away from each other to complete the dynamic shearing of the moving ultra-thin strip.

[0039] Please refer to Figure 3 In an optional embodiment, the guide adopts four sets of precise linear guide pairs, and other numbers of groups can also be provided. The linear guide pair comprises a guide rail 407 and a sliding block 408. The guide is installed on the inlet side and the outlet side of the lower blade seat 403 and the upper blade seat 404. On the inlet side of the shearing mechanism 400, the guide rail 407 is connected with the lower blade seat 403, and the sliding block 408 should be installed on the upper blade seat 404. On the outlet side of the shearing mechanism 400, the guide rail 407 is connected with the upper blade seat 404, and the sliding block 408 should be installed on the lower blade seat 403. Thus, the lower blade seat 403 and the upper blade seat 404 are limited to relative movement in the vertical direction. The linear guide pair has high movement precision. During the shearing process, the shear blade gap between the upper blade 406 and the lower blade 405 in the shearing mechanism 400 is kept constant, realizing the shearing of the metal ultra-thin strip. The linear guide pair has high movement precision, which can ensure the constant shear blade gap between the upper blade 406 and the lower blade 405 in the shearing mechanism 400 during the shearing process, ensure the movement precision and stability in the vertical direction, and realize the shearing of the metal ultra-thin strip.

The first gear 303, the second gear 306 and the third gear 308 in the transmission mechanism 300 are all helical gears, and the rotation directions of the gears on the driving side and the operation side are opposite, so that the axial forces of the helical gears on the two sides are offset.

[0043] In an alternative embodiment, the transmission mechanism 300 comprises two sets (note: a single synchronous shaft 301), one located at each end of the shearing mechanism 400. Both ends of the synchronous shaft 301 are connected to the machine body 200 and are rotatable. Power is input to the drive mechanism 100 from one end of the synchronous shaft 301. Through the transmission mechanism 300, the ends of the synchronous shaft 301 are respectively connected to the ends of the lower blade shaft 401, which in turn are connected to the ends of the upper blade shaft 402. The lower blade seat 403 and the upper blade seat 404 are connected to the midsection of the lower and upper blade shafts 401 and 402, respectively.

[0044] In an alternative embodiment, the machine body 200 includes a drive-side frame 201, an operating-side frame 202, and a crossbeam 203. The ends of the crossbeam 203 are connected to the drive-side frame 201 and the operating-side frame 202, respectively, and can be secured with bolts and locating pins. The drive-side frame 201 and the operating-side frame 202 are rotationally connected to the lower eccentric sleeve 305, the upper eccentric sleeve 307, and the synchronous shaft 301. The machine body 200 also includes an eccentric sleeve bearing 204 and a synchronous shaft bearing 205, which are respectively mounted on the left and right sides of the drive-side frame 201 and the operating-side frame 202. The drive-side frame 201 and the operating-side frame 202 each have three bearing seat holes, each housing a set of synchronous shaft bearings 205 and two sets of eccentric sleeve bearings 204. One set of eccentric sleeve bearings 204 is connected to the lower eccentric sleeve 305, while the other set of eccentric sleeve bearings 204 is connected to the upper eccentric sleeve 307.

For example, the output end of the motor 101 is connected with the input end of the speed reducer 103, and the output end of the speed reducer 103 is connected with the synchronous shaft 301. The driving mechanism 100 further comprises a first coupling 102 and a second coupling 104, one end of the first coupling 102 is connected with the output end of the motor 101, and the other end is connected with the input end of the speed reducer 103, one end of the second coupling 104 is connected with the output end of the speed reducer 103, and the other end is connected with the end of the synchronous shaft 301.

Through the output speed control of the driving mechanism 100, the shearing mode can be set according to the program, and single-knife shearing and multi-knife continuous shearing can be performed. In the continuous shearing mode, the number of blocks of the sample to be sheared and the length of the sample can be set.

[0046] The specific process of the shearing operation of the present application is as follows:

[0047] The torque output by the motor 101 is reduced and increased in torque by the speed reducer 103, and then transmitted to the synchronous shaft 301 through the second coupling 104.

The first gear 303 is engaged with the second gear 306, and the second gear 306 is engaged with the third gear 308. The power is transmitted to the lower eccentric sleeve 305 and the upper eccentric sleeve 307 through the second key 304, respectively.

The lower knife seat 403 is rotatably connected with the lower knife shaft 401, and the upper knife seat 404 is rotatably connected with the upper knife shaft 402. The precise constraint of the four linear guide pairs installed on both sides of the lower knife seat 403 and the upper knife seat 404 makes the lower knife seat 403 and the upper knife seat 404 always move horizontally in the vertical direction. The lower blade 405 and the upper blade 406 fixed on the lower knife seat 403 and the upper knife seat 404 always maintain perpendicularity with the strip to be sheared and have a constant side gap value. During the shearing process, the lower blade 405 and the upper blade 406 simultaneously perform mutual up-down movement of closing and opening, thereby completing the dynamic shearing of the moving ultra-thin strip.
