[0001] The utility model relates to the technical field of flame-retardant optical cable processing, in particular to a cutting device for flame-retardant optical cables. Background Art

[0004] When the flame-retardant optical cable is cut, the cutting blade is moved downward to cut it. However, during the cutting operation, since the flame-retardant cable is cylindrical in shape, the cutting knife is prone to slip when it first contacts the outer surface of the flame-retardant cable, causing the position of the cutting knife to shift from the flame-retardant cable, and the flame-retardant cable is not cut quickly, reducing the cutting efficiency of the device.

[0005] In view of the above problems, a cutting device for flame-retardant optical cables is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a cutting device for flame-retardant optical cables. When the device is used for working, during the cutting operation, since the flame-retardant cable is cylindrical in shape, the cutting knife is prone to slip when it just contacts the outer surface of the flame-retardant cable, thereby causing the position of the cutting knife to shift from the flame-retardant cable, and the flame-retardant cable is not cut quickly, which reduces the cutting efficiency of the device, thereby solving the problems in the above background.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 4 The adjustment assembly 7 includes two U-shaped rods 71 ​​fixedly installed on the top of the connecting block 5 near the front and rear sides and a fixing plate 72 fixedly installed at the ends of the U-shaped rods 71. The inner cavity of the fixing plate 72 is slidably penetrated by a connecting rod 73, and the ends of the connecting rod 73 are fixedly installed with moving blocks 74, which can enable the two moving blocks 74 to move to opposite sides.

[0027] An inclined groove 721 is provided on one side of the fixing plate 72, and the output ends of the connecting rods 73 are movable through the inner cavity of the inclined groove 721, so that the connecting rods 73 can slide in the inner cavity of the inclined groove 721, which is convenient for subsequent fixing work.

[0028] A limiting block 741 is fixedly installed at the bottom of the moving block 74, and a limiting groove 742 is provided on the top of the cutting table 3 near the front and rear sides, and the limiting blocks 741 are slidably connected in the inner cavity of the adjacent limiting grooves 742, and two balls 743 are provided at the bottom of the limiting block 741. A rolling groove 744 is provided at the bottom of the inner cavity of the limiting groove 742, and the balls 743 are slidably connected in the inner cavity of the adjacent rolling groove 744. By arranging the balls 743 to slide in the inner cavity of the rolling groove 744, the smoothness of the movement of the limiting block 741 can be improved.

[0029] Specifically, by placing the flame-retardant cable on the top of the conveyor body 2, the conveyor body 2 is started to convey the cable to the top surface of the cutting table 3, and then the conveyor body 2 is stopped. At this time, the connecting block 5 is pushed downward by the electric telescopic rod 4, and the flame-retardant cable is cut by the cutting knife 6 fixed on the connecting block 5. When the connecting block 5 moves downward, the U-shaped rod 71 fixed on the connecting block 5 can make the adjacent fixed plate 72 move downward. With the cooperation of the inclined groove 721, the connecting rod 73 can slide in the inner cavity of the inclined groove 721, and the moving block 74 fixed on the connecting rod 73 can slide in the inner cavity of the limiting groove 742 under the connection of the limiting block 741, so that the two moving blocks 74 move to the opposite side. By setting the ball 743 to slide in the inner cavity of the rolling groove 744, the smoothness of the movement of the limiting block 741 can be improved, and then the flame-retardant optical cable can be fixed, which is conducive to the rapid cutting of the flame-retardant optical cable and improves the cutting efficiency of the device.

[0030] Embodiment 2:

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 5A support block 11 is fixedly installed at the bottom of the base 1 near both sides, a U-shaped plate 41 is fixedly installed at the top of the electric telescopic rod 4, and the front side of the U-shaped plate 41 is fixedly installed at the rear side of the cutting table 3, and a rectangular opening 31 is opened at the top of the cutting table 3 near one side (the fixed plate 72 can penetrate the inner cavity of the rectangular opening 31 when it moves downward).

[0032] The fixing assembly 8 includes a plurality of limiting telescopic rods 81 fixedly mounted on the moving block 74, and a round block 82 is fixedly mounted at the end of each of the limiting telescopic rods 81 (the plurality of limiting telescopic rods 81 and the plurality of round blocks 82 are linearly arranged from top to bottom in sequence), which can contact the flame-retardant cable to be cut through the round block 82, thereby limiting its position.

[0033] A spring 811 is movably sleeved on the outer circumference of the limiting telescopic rod 81, and both ends of the spring 811 are respectively fixedly mounted on the round block 82 and the adjacent moving block 74. The provision of the spring 811 can improve the flame retardant fixing effect of the round block 82.

[0034] Specifically, the fixing effect of the flame-retardant cable can be improved by using the position-limiting telescopic rod 81 provided on the moving block 74 in cooperation with the round block 82 fixed on the position-limiting telescopic rod 81 and the spring 811.

[0035] In summary, the flame-retardant cable is placed on the top of the conveyor body 2, the conveyor body 2 is started to convey the cable to the top surface of the cutting table 3, and then the conveyor body 2 is stopped. At this time, the connecting block 5 is pushed downward by the electric telescopic rod 4, and the cutting knife 6 fixed on the connecting block 5 is used to cut the flame-retardant cable. When the connecting block 5 moves downward, the U-shaped rod 71 fixed on the connecting block 5 can make the adjacent fixing plate 72 move downward, and under the cooperation of the inclined groove 721, the connecting rod 73 can slide in the inner cavity of the inclined groove 721, so that the connecting rod 73 fixed on the connecting block 5 can slide downward. The moving block 74 on the rod 73 slides in the inner cavity of the limiting groove 742 when connected with the limiting block 741, so that the two moving blocks 74 move to the opposite side. By arranging the ball 743 to slide in the inner cavity of the rolling groove 744, the smoothness of the movement of the limiting block 741 can be improved, and the flame-retardant optical cable can be fixed, which is beneficial to the rapid cutting of the flame-retardant optical cable and improves the cutting efficiency of the device. By the coordinated use of the limiting telescopic rod 81 set on the moving block 74 and the round block 82 fixed on the limiting telescopic rod 81 and the spring 811, the fixing effect of the flame-retardant cable can be improved.
