The first shaft 343 drives the first cam 351 to rotate. The first cam 351 drives the first connecting rod 352 to swing up and down through the first pin shaft 356; the second connecting rod 354 is driven by the first connecting rod 355. 53 is in a vertical state or a nearly vertical state, the first connecting rod 352 drives the second connecting rod 353 to move up and down, the second connecting rod 353 is provided with a plurality of holes 3531, the first connecting rod 352 and the second connecting rod 353 are hinged at one of the holes 3531, so as to adjust the swing amplitude of the second connecting rod 353, thereby adjusting the swing amplitude of the first tip 32 and the second tip 33; the second connecting rod 353 drives the first swing rod 354 to swing back and forth, and the first swing rod 354 drives the second shaft 355 to rotate back and forth. Fig.11 The first cam 351 includes three working areas, namely, the BA area, the AC area and the CB area, and the rotation center of the first cam 351 is O; when the first pin shaft 356 moves in the BA area, since the movement radius of the BA area remains unchanged, in this area, the first tip 32 and the second tip 33 do not swing; when the first pin shaft 356 moves in the AC area, since the movement radius of the AC area gradually increases, the first pin shaft 356 gradually drives the first connecting rod 352 to swing upward, and then through the second connecting rod 353, the first swing rod 354 and the second shaft 355 drives the first tip 32 and the second tip 33 to swing upward from the flat rope 4 as the starting point; when the first pin shaft 356 moves in the CB area, since the movement radius of the CB area gradually decreases, the first pin shaft 356 gradually drives the first connecting rod 352 to swing downward, and then drives the first tip 32 and the second tip 33 to swing from the top of the arc plate 31 to the flat rope 4 through the second connecting rod 353, the first swing rod 354 and the second shaft 355, and repeats this cycle to achieve the reciprocating swing of the first tip 32 and the second tip 33 along the arc plate 41.

[0060] See also Figures 7 to 12, the driving forces of the first driving assembly 35 and the second driving assembly 36 are both derived from the first shaft 343, and the working principle of the second driving assembly 36 is as follows: the second driving assembly 36 includes a plurality of first transmission gears 361 and a second cam assembly 362 driven by the first shaft 343, the second cam assembly 362 is rotatably mounted on the second shaft 355, a second transmission gear 363 is arranged on the outer side wall of the second cam assembly 362, the first transmission gear 361 is meshed with the second transmission gear 363; the second cam assembly 362 drives the third shaft 365 to rotate through the second swing rod 364; the second cam assembly 362 includes a cam plate 3621 and a second cam 3622, the second cam 3622 is provided with an arc-shaped waist hole 3623, and the installation angle of the second cam 3622 can be finely adjusted through the arc-shaped waist hole 3623, so as to accurately adjust the rotation trajectory of the third shaft 365; see Fig.12 The rotation center of the second cam 3622 is F. The second cam 3622 includes two working areas, namely the ED area and the DE area. Auxiliary circles G and H are drawn with F as a circle. The radius of the auxiliary circle H is greater than the radius of the auxiliary circle G. The ED area coincides with the partial arc of the auxiliary circle G, and the DE area coincides with the partial arc of the auxiliary circle H. The connection between the ED area and the DE area has a transition arc; the third pin shaft 366 rotates along the ED area and the DE area. When the third pin shaft 366 moves along the ED area, it cannot drive the second swing rod 364, and thus cannot drive the first tip 32 and the second tip 33 to roll down the flat rope 4 through the third shaft 365; the third pin shaft 366 During the transition from the ED zone to the DE zone, the rotation radius of the third pin shaft 366 first decreases and then remains unchanged, so that the second swing rod 364 drives the first tip 32 and the second tip 33 to press the flat rope 4 downward and maintain a certain distance (this distance corresponds to the process of the first tip 32 and the second tip 33 moving upward along the arc plate 31). During the transition from the DE zone to the ED zone, the rotation radius of the third pin shaft 366 first increases and then remains unchanged, so that the second swing rod 364 drives the first tip 32 and the second tip 33 to move away from the flat rope 4 and maintain a certain distance (this distance corresponds to the process of the first tip 32 and the second tip 33 returning along the arc plate).

[0061] See also Fig.10In order to fasten the first tip 32 and the second tip 33, a first swinging member 367 and a second swinging member 368 are provided on the third shaft 365; a first column 3671 is provided at the end of the first swinging member 367, a first clamping groove 3672 is provided at the end of the first column 3671, a first thin column 3673 is provided in the first clamping groove 3672, the first tip 32 is vertically inserted into the first thin column 3673, or the first tip 32 is vertically fixed to the first thin column 3673, when the first tip 32 pushes the flat rope 4 to move along the arc plate 31, due to the first thin column 3673 Clamped in the first clamping groove 3672, the first tip 32 will not be distorted; a second column 3681 is set at the end of the second swinging member 368, and a second clamping groove 3682 is set at the end of the second column 3681. A second thin column 3683 is set in the second clamping groove 3682, and the second tip 33 is vertically inserted into the second thin column 3683, or the second tip 33 is vertically fixed to the second thin column 3683. When the second tip 33 pushes the flat rope 4 to move along the arc plate 31, the second tip 33 will not be distorted because the second thin column 3683 is clamped in the second clamping groove 3682.

[0062] See also Figure 7 The flat rope 4 is in a flat long rectangular shape; the first slit 311 is connected to the flat rope receiving groove 22, the second slit 312 is connected to the flat rope receiving groove 22, the first slit 311 and the second slit 312 are arranged in parallel and penetrate the arc plate 31, and the flat rope 4 is placed in the flat rope receiving groove 22. Figure 7 The working process of the flat rope exporting device is as follows: in the first step, the flat rope 4 is transported to the flat rope accommodating groove 22; in the second step, the first driving component 35 drives the first tip 32 and the second tip 33 to align with the flat rope 4, and the second driving component 36 drives the first tip 32 and the second tip 33 to move downward and insert the first tip 32 and the second tip 33 into the edge of the flat rope 4; in the third step, the second driving component 36 keeps the first tip 32 and the second tip 33 inserted into the flat rope 4, and the first driving component 35 drives the first tip 32 and the second tip 33 to move along the arc plate 31 at the same time, the first tip 32 moves along the first gap 311 to the top of the arc plate 31, and the second tip 33 moves along the second gap 312 to the top of the arc plate 31; in the fourth step, the second driving component 35 drives the first tip 32 and the second tip 33 away from the flat rope 4 at the top of the arc plate 31 to complete the export of the flat rope 4.

[0063] See also Figure 4The working principle of the swing assembly 25 is as follows: a third cam 3624 is set on the cam plate 3621; the swing assembly 25 includes a third swing rod 251, a swing shaft 252 and a fourth swing rod 253, and a tension spring 254 and a second pin shaft 255 are set at the end of the third swing rod 251. The third cam 3624 drives the third swing rod 251 to swing through the second pin shaft 255, and the end of the tension spring 254 is fastened to the first vertical wall 341; the third swing rod 251 drives the fourth swing rod 253 to swing through the swing shaft 252, and the fourth swing rod 253 drives the first conveyor belt 23 to approach or move away from the flat rope. The first conveyor belt 23 rotates around the first guide wheel 231 and other guide wheels, and the second conveyor belt 24 rotates around the second guide wheel 241 and other guide wheels. When clamping the flat rope 4, the second pin shaft 255 moves against the convex surface of the third cam 3624, so that the first guide wheel 231 drives the first conveyor belt 23 to press down the flat rope 4; when it is necessary to guide out the flat rope 4, the second pin shaft 255 moves against the concave surface of the third cam 3624, so that the first guide wheel 231 drives the first conveyor belt 23 to rise and loosen the flat rope 4. Since the width of the flat rope 4 is greater than the width of the first conveyor belt 23, there will be no interference when the first tip 32 and the second tip 33 are inserted into the edge of the flat rope 4.
