Figure 2 The working process of the flat rope introduction device is as follows: in the first step, the flat rope 5 is placed in the flat rope accommodating groove 61; in the second step, the first driving component 2 drives the first tip 426 and the second tip 427 to align with the flat rope 5, and the second driving component 3 drives the first tip 426 and the second tip 427 to move downward and insert the first tip 426 and the second tip 427 into the flat rope 5; in the third step, the second driving component 3 keeps the first tip 426 and the second tip 427 inserted into the flat rope 5, and the first driving component 2 drives the first tip 426 and the second tip 427 to move along the arc plate 41 at the same time, the first tip 426 moves along the first gap 411 to the top of the arc plate 41, and the second tip 427 moves along the second gap 412 to the top of the arc plate 41; in the fourth step, the second driving component 3 drives the first tip 426 and the second tip 427 away from the flat rope 5 at the top of the arc plate 41 to complete the introduction of the flat rope.

Figure 7 The first cam 21 includes three working areas, namely, the BA area, the AC area and the CB area, and the rotation center of the first cam 21 is O; when the first pin shaft 25 moves in the BA area, since the movement radius of the BA area remains unchanged, in this area, the first tip 426 and the second tip 427 do not swing; when the first pin shaft 25 moves in the AC area, since the movement radius of the AC area gradually increases, the first pin shaft 25 gradually drives the first connecting rod 22 to swing upward, and then drives the first tip 426 and the second tip 427 to swing upward from the flat rope 5 as the starting point through the second connecting rod 23, the first swing rod 24 and the second shaft 42; when the first pin shaft 25 moves in the CB area, since the movement radius of the CB area gradually decreases, the first pin shaft 25 gradually drives the first connecting rod 22 to swing downward, and then drives the first tip 426 and the second tip 427 to swing from the top of the arc plate 41 to the flat rope 5 as the starting point through the second connecting rod 23, the first swing rod 24 and the second shaft 42, and repeats this cycle to achieve the reciprocating swing of the first tip 426 and the second tip 427 along the arc plate 41.

[0033] See also Figures 3 to 8, the driving forces of the first driving assembly 2 and the second driving assembly 3 are both derived from the first shaft 13, and the working principle of the second driving assembly 3 is as follows: the second driving assembly 3 includes a plurality of first transmission gears 31 and a second cam assembly 32 driven by the first shaft 13, the second cam assembly 32 is rotatably mounted on the second shaft 42, a second transmission gear 33 is arranged on the outer side wall of the second cam assembly 32, the first transmission gear 31 meshes with the second transmission gear 33; the second cam assembly 32 drives the third shaft 423 to rotate through the second swing rod 34; the second cam assembly 32 includes a cam plate 321 and a second cam 322, the second cam 322 is provided with an arc-shaped waist hole 323, and the installation angle of the second cam 322 can be fine-tuned through the arc-shaped waist hole 323, thereby accurately adjusting the rotation trajectory of the third shaft 423; see Figure 8 The rotation center of the second cam 322 is F. The second cam 322 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 second pin shaft 35 rotates along the ED area and the DE area. When the second pin shaft 35 moves along the ED area, it cannot drive the second swing rod 34, and further cannot drive the first tip 426 and the second tip 427 to roll down the flat rope 5 through the third shaft 423; the second pin shaft 35 is formed by the ED During the transition from zone DE to zone DE, the rotation radius of the second pin shaft 35 first decreases and then remains unchanged, so that the second swing rod 34 drives the first tip 426 and the second tip 427 to roll down the flat rope 5 and maintain a distance (this distance corresponds to the process of the first tip 426 and the second tip 427 moving upward along the arc plate 41), and during the transition from zone DE to zone ED, the rotation radius of the second pin shaft 35 first increases and then remains unchanged, so that the second swing rod 34 drives the first tip 426 and the second tip 427 to move away from the flat rope 5 and maintain a distance (this distance corresponds to the process of the first tip 426 and the second tip 427 returning along the arc plate).

[0034] See also Figure 6In order to fasten the first tip 426 and the second tip 427, a first column 4241 is provided at the end of the first swinging member 424, a first clamping groove 4242 is provided at the end of the first column 4241, a first thin column 4243 is provided in the first clamping groove 4242, the first tip 426 is vertically inserted into the first thin column 4243, or the first tip 426 is vertically fixed to the first thin column 4243, when the first tip 426 pushes the flat rope 5 to move along the arc plate 41, since the first thin column 4243 is clamped in the first clamping groove 4242, the first thin column 4243 is clamped in the first clamping groove 4242. A tip 426 will not be distorted; a second column 4251 is set at the end of the second swing member 425, a second clamping groove 4252 is set at the end of the second column 4251, a second thin column 4253 is set in the second clamping groove 4252, and the second tip 427 is vertically inserted into the second thin column 4253, or the second tip 427 is vertically fixed to the second thin column 4253. When the second tip 427 pushes the flat rope 5 to move along the arc plate 41, the second tip 427 will not be distorted because the second thin column 4253 is clamped in the second clamping groove 4252.

[0035] The beneficial effect of Example 1 is: when the first driving component 2 drives the first tip 426 and the second tip 427 to align with the flat rope 5 in a downward posture, the second driving component 3 drives the first tip 426 and the second tip 427 to move downward and insert the first tip 426 and the second tip 427 into the flat rope 5, the first driving component 2 continues to move and drives the first tip 426 and the second tip 427 to move upward along the arc plate 41 through the second axis. During this process, the first tip 426 moves along the first gap 411 and the second tip 427 moves along the second gap 412 until the flat rope 5 is sent to the next process, and this cycle is repeated to continuously supply the flat rope to the next process, thereby realizing continuous and automatic introduction of the flat rope with high introduction efficiency.
