The cable sheath is generally made of polyethylene. The black high-density polyethylene material used as the sheath material is made of a high-density polyethylene base resin specially used for the sheath material, and high-quality carbon black masterbatch and other related processing aids are added to mix and granulate. The content of high-quality carbon black masterbatch, carbon black particle size, dispersion and other factors have a huge impact on the long-term performance of the optical cable, such as resistance to ultraviolet radiation aging and heat aging.

[0030] The outer side of the first driving rod 4 is connected to a toggle block 8, and a first filter screen 10 is arranged below the toggle block 8. The large raw material particles screened above the first filter screen 10 are toggled to the top of the second filter screen 11 through the toggle block 8. The second filter screen 11 is connected below the first filter screen 10, and a cutting knife 9 is arranged above the second filter screen 11. The cutting knife 9 is used to cut the large raw materials to facilitate subsequent processing. A connecting rod 7 is connected above the cutting knife 9.

[0031] See the attached drawings in the specification Figure 1-4 The device body 1 and the feed port 2 are installed in an integrated manner. The center point of the feed port 2 and the center point of the first driving rod 4 are above the same horizontal line. The first stirring rods 3 are evenly and equidistantly distributed on the outside of the first driving rod 4. The first driving rod 4 cooperates with the first stirring rod 3 to stir the feed port 2 to prevent raw materials from piling up.

[0032] See the attached drawings in the specification Figure 1-4 The first driving rod 4 and the double-axis motor 5 are connected in a key connection manner, and the double-axis motor 5 and the second driving rod 13 are connected in a key connection manner. The double-axis motor 5 is integrated with the device body 1 through the protective shell 6. The first driving rod 4 and the second driving rod 13 are driven to rotate by the double-axis motor 5, so that the equipment can be operated in an integrated manner, reducing the structure and production costs.

[0033] See the attached drawings in the specification Figure 1-4 The connecting rod 7 and the first driving rod 4 rotate in an integrated manner, and the connecting rod 7 and the cutting knife 9 are connected by hot melt connection. The sum of the lengths of the cutting knife 9 is consistent with the width of the second filter screen 11.

At this time, the first driving rod 4 starts to move with the dual-axis motor 5, driving the first stirring rod 3 to rotate to avoid blockage during the feeding process. After that, the raw material falls on the top of the first filter screen 10. At this time, the toggle block 8 rotates together to make the raw material rotate. The raw material of appropriate size directly passes through the first filter screen 10 and falls below. The larger raw material falls on the top of the second filter screen 11 on the outside due to the centrifugal force. The cutting knife 9 rotates integrally with the first driving rod 4 through the connecting rod 7, so as to cut the large piece of raw material. After cutting, the raw material passes through the second filter screen 11 and falls below. When the raw material falls on the top of the guide block 12, it converges at the discharge port in the center direction. The second stirring rod 14 and the second driving rod 13 are switched on and off with the switch of the dual-axis motor 5 to avoid blockage of the discharge port.
