[0023] Reference Figures 1 to 5 In this embodiment of the utility model, a fiber optic preform cone head processing device includes a machine bed 1, a clamping mechanism 2 for clamping the preform is fixedly installed at the top of the machine bed 1, a grinding mechanism 4 is fixedly installed at the top of the machine bed 1 on the side opposite to the clamping mechanism 2, a cutting mechanism 3 for cutting the preform is fixedly installed at the top of the machine bed 1, a cooling water tank 6 for collecting cooling water is opened at the top of the machine bed 1, a cooling water pipe 8 is fixedly installed at the top of the machine bed 1 on one side of the cooling water tank 6, an installation support frame 9 is fixedly installed inside the cooling water tank 6, and the installation support frame 9 is symmetrically fixed inside the cooling water tank 6. A filter screen plate 10 for separating cooling water and grinding waste is fixedly installed at the top of the installation support frame 9, and a cleaning plate 11 for reducing the accumulation of waste in one place is provided at the top of the filter screen plate 10.

[0024] The implementation of this method involves placing the filter screen 10 into the top of the symmetrically fixed mounting support frame 9 inside the cooling water tank 6. Then, the preform is clamped by the clamping mechanism 2, and the grinding mechanism 4 and the cutting mechanism 3 are started by the control cabinet 7 to process the preform. At the same time, the cutting head of the cutting mechanism 3 is cooled by the cooling water pipe 8. The cooling water, cutting and grinding waste fall into the cooling water tank 6 for collection. The filter screen 10 inside the cooling water tank 6 can screen the cooling water and cutting and grinding waste, reducing the mixing of waste with the cooling water and affecting the secondary use of the cooling water.

[0025] Reference Figures 1 to 5 A guide block 12 for sliding is fixedly installed at one end of the cleaning plate 11, and a sliding block 13 for driving the cleaning plate 11 to slide back and forth is fixedly installed at one end of the cleaning plate 11. A connecting arm 21 is provided inside the machine tool bed 1, and a connecting plate 19 is fixedly installed at one end of the sliding block 13 through the cooling water tank 6. A slot 22 is opened at one end of the connecting arm 21, and a connecting block 20 adapted to the slot 22 is fixedly installed at one end of the connecting plate 19. A rotating disk 28 is rotatably connected inside the machine tool bed 1, and a connecting arm 23 is fixedly installed at one end of the rotating disk 28. A connecting block 27 adapted to the slot 22 is rotatably connected at one end of the connecting arm 23. A rotating motor 24 for driving the rotating disk 28 to rotate is fixedly installed at one end of the machine tool bed 1. A sliding groove 25 for the guide block 12 to slide is opened inside the cooling water tank 6, and a slider 18 adapted to the sliding groove 25 is fixedly installed at one end of the guide block 12.

[0026] By implementing this method: by starting the rotating motor 24, the rotating motor 24 drives the second connecting arm 23 to rotate, and then the second connecting block 27 drives the first connecting arm 21 to reciprocate inside the machine tool bed 1. Then, the first connecting block 20 and the connecting plate 19 drive the sliding block 13 to slide. Through the sliding of the sliding block 13, the cleaning plate 11 can be driven to reciprocate to clean the surface of the filter screen plate 10, reducing the accumulation of grinding and cutting waste in one place and preventing blockage.

[0027] Reference Figures 1 to 5 The cleaning plate 11 is symmetrically fixed at both ends with fixing plates 15 for fixing, and the top of the guide block 12 and the sliding block 13 are both provided with fixing grooves 14 that are adapted to the fixing plates 15. The top of the fixing plate 15 is provided with fixing holes 16, and the fixing holes 16 are threadedly connected to threaded rods 17.

[0028] By implementing this method, the filter screen 10 can be disassembled and replaced from the top of the sliding block 13 and the guide block 12 via the threaded rod 17, the fixing hole 16, the fixing plate 15 and the fixing groove 14.

[0029] Reference Figures 1 to 5A protective cover 5 is rotatably connected to the top of the machine tool bed 1, and a control cabinet 7 is fixedly installed on the top of the machine tool bed 1.

[0030] The working principle of this utility model is as follows: When processing the preform, the filter screen 10 is first placed on the top of the symmetrically fixed mounting support frame 9 inside the cooling water tank 6. Then, the preform is clamped by the clamping mechanism 2, and the grinding mechanism 4 and the cutting mechanism 3 are started by the control cabinet 7 to process the preform. At the same time, the cutting head of the cutting mechanism 3 is cooled by the cooling water pipe 8. The cooling water, cutting and grinding waste fall into the cooling water tank 6 for collection. The filter screen 10 inside the cooling water tank 6 can filter the cooling water and cutting and grinding waste. The screening process reduces the mixing of waste materials with cooling water, thus minimizing the impact on the reuse of cooling water. Simultaneously, the operator starts the rotating motor 24, which drives the connecting arm 23 to rotate. This, in turn, drives the connecting arm 21 to reciprocate within the machine tool bed 1 via the connecting block 27. Furthermore, the connecting block 20 and the connecting plate 19 drive the sliding block 13 to slide. The sliding of the sliding block 13 enables the cleaning plate 11 to reciprocate and clean the surface of the filter screen 10, reducing the accumulation of grinding and cutting waste materials and preventing blockages.
