The cone head needs to be cut off. At this time, the control module is started, the cone shearing frequency is set, and the drive motor starts working through the power line. The rotation of the motor causes the rotating disk to rotate, which in turn drives the rear end of the crank structure to rotate, and pushes the rear convex drive mechanism forward, which in turn drives the linear moving block forward. In the initial stage, the forward force is not greater than the pressure of the linear spring.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] An automatic fiber taper cutting device, see Figure 1-Figure 2 , which includes a mounting base 10, a control module 20, a scissor assembly 30, a motor drive assembly 40, a crank mechanism 50, a shear cone cylinder 60, and a scissor drive assembly 70;

[0025] The mounting base 10 includes a motor mounting plate 11 and a guide seat body 12;

[0026] The scissor assembly 30 includes a scissor body 80 and a bracket 90. The scissor body 80 includes a pair of scissor arms 81. The bracket 90 includes a front scissor arm mounting bracket 91 and a rear linear travel driving bracket 92.

[0027] The motor drive assembly 40 includes a motor 41 and a rotating disc 42;

[0028] The scissor drive assembly 70 includes a guide frame 71 and a rear convex drive mechanism 72. The guide frame 71 includes two front convex guide frames 73 and a linear moving block 74. The rear end of the linear moving block 74 is provided with the rear convex drive mechanism 72.

[0029] The motor 41 is fixedly mounted on the back side of the motor mounting plate 11. The output shaft of the motor 41 passes through the motor mounting plate 11 and is fixedly sleeved with a rotating disc 42. The radial outer end of the rotating disc 42 is provided with a protruding shaft 43. The rear end of the crank mechanism 50 is pivotally connected to the protruding shaft 43. The front end of the crank mechanism 50 is pivotally connected to the rear protruding end of the rear protruding driving mechanism 72. A pair of linear bearings 100 are fixedly mounted on the guide seat body 12. The corresponding guide shafts 110 are inserted into the inner cavity of the linear bearings 100 and protrude forward and are respectively fixed to the rear end linear driving mechanism 72. On the corresponding end side of the moving bracket 92, the front convex plate 93 of the front scissor arm mounting bracket 91 is respectively connected to a pair of scissor arms 81 through a rotating shaft 931, and the non-scissor end of the scissor arm 81 is driven to open or close by the front convex guide frame 73 on the corresponding side. The front convex guide frames 73 on both sides move in a telescopic manner along the travel direction of the guide shaft 110. A linear spring 120 is arranged between the linear moving block 74 and the rear end linear travel driving bracket 92, and a limiting mechanism 130 is arranged on the rear end sleeve of each group of guide shafts 110 corresponding to the linear bearing 100;

[0030] The control module 20 is connected to the motor 41 through the wire 21, and a shear cone 60 is arranged just below the shearing area of ​​the scissor arm 81.

[0031] During specific implementation, the rear end linear motion driving bracket 92 includes a connecting plate 94 and connecting ends 95 on both sides. The linear moving block 74 is located in the area between the connecting ends 95 on both sides and is arranged parallel to the connecting plate 94. Linear springs 120 are respectively arranged at both ends in the length direction of the linear moving block 74. The linear springs 120 are respectively installed between the connecting plate 94 and the linear moving block 74. When the optical fiber is not cut, the rear end of the crank mechanism 50 is located at the radial rear end position of the rotating disk 42. The linear spring 120 is installed on the linear moving block 74, so that the linear moving block 74 is in the rearmost position. When the optical fiber needs to be cut, the motor 41 drives the rotating disk 42 to rotate, thereby driving the rear end of the crank mechanism 50 to rotate, pushing the rear convex driving mechanism 72 to move linearly. The linear moving block 74 moves forward, and in turn drives the linear moving block 74 forward. In the initial stage, the forward force is not greater than the elastic force of the linear spring 120. The linear moving block 74 transmits the forward force to the connecting plate 94 through the linear spring 120, and then drives the entire scissors drive assembly 70 and the scissors assembly 30 to move forward until the limiting mechanism 130 of the guide shaft 110 is limited at the rear end of the linear bearing 100. At this time, the front end of the crank mechanism 50 still moves forward, so that the linear moving block 74 overcomes the elastic force of the linear spring 120 and moves forward, and then drives the forward convex guide frame 73 to move forward relative to the front end scissor arm mounting bracket 91, and the non-scissor end of the scissor arm 81 is driven by the forward convex guide frame 73 on the corresponding side to close the cone of the optical fiber, and the cut cone head falls into the lower cone cutting cylinder 60.

[0032] In specific implementation, the non-scissor end of the scissor arm 81 is provided with a driving end, and the driving end is provided with a plug-in notch 811. The forward protruding guide frame 73 on each side is provided with an insertion shaft 731, and the insertion shaft 731 is inserted into the plug-in notch 811, which makes the driving of the scissor arm 81 stable and reliable.

[0033] In a specific implementation, a guide protrusion shaft 96 is provided in the connection plate 94 corresponding to the notch area of ​​the front convex guide frame 73 , and the guide protrusion shaft 96 guides the reliable linear movement of the front convex guide frame 73 .

[0034] In specific implementation, the limiting mechanism 130 is specifically a locking ring sleeve, which ensures that the mechanism is reliably installed and convenient for adjusting the distance.

[0035] Its working principle is as follows: when the optical fiber preform is drawn online, a small cone head will remain after the cone of the preform is heated and melted in the drawing furnace for a certain period of time. The cone head needs to be removed. At this time, the control module is started, the cone shearing frequency is set, and the drive motor is powered on through the wires to start working. The rotation of the motor causes the rotating disk to rotate, and the rotating disk rotates, thereby driving the rear end of the crank mechanism to rotate, pushing the rear convex drive mechanism to move in a straight line, and then driving the linear moving block forward. In the initial stage, the forward force is not greater than the elastic force of the linear spring. The linear moving block transmits the forward force to the connecting plate through the linear spring, thereby driving the entire scissors drive assembly and the scissors assembly to move until the guide shaft. The limiting mechanism is limited at the rear end of the linear bearing. At this time, the front end of the crank mechanism still moves forward, so that the linear moving block overcomes the elastic force of the linear spring and moves forward, thereby driving the convex guide frame to move forward relative to the front end scissor arm mounting bracket, and the non-scissor end of the scissor arm is driven by the convex guide frame on the corresponding side to close the cone of the optical fiber, and the cut cone head falls into the cone shearing cylinder below; then the motor continues to rotate and reset, and each component resets. When the melting and descending speed of the preform rod speeds up or slows down, the running speed of the motor is adjusted through the control module, thereby adjusting the cone shearing frequency to match the change of the cone shearing speed; it reduces labor costs and improves the safety production factor.
