A production line for PE optical cable sheath material

Abstract

The invention relates to a pe optical cable jacket material production line. The production line consists of a weighing device, a plastic defoamer adding device, an automatic loading machine, a horizontal drying machine, a collecting hopper, an automatic feeding device, a granulator, a vacuum pumping device, a cooling device, a strip shaking machine, a horizontal rubber cutting machine, a cold wind conveying device and a packaging device. The weighing device, the automatic loading machine, the horizontal drying machine, the collecting hopper, the automatic feeding device, the granulator, the cooling device, the strip shaking machine, the horizontal rubber cutting machine, the cold wind conveying device and the packaging device are connected in series to compose the production line. The plastic defoamer adding device includes a pedestal, the top of the pedestal is connected to a storage tank through a prop, the top of the storage tank is connected to a feed pipe, and the bottom of the storage tank is connected to an inclined discharge pipe. Through the design of adding a plastic defoamer into the raw materials and then cooperating vacuum pumping during granulation, the production line can achieve the effect of forced extraction of all exhaust gas and small molecular substances from the raw materials, can improve the workshop environment, and does not affect the physical and mental health of employees.

Description

technical field [0001] The invention relates to the technical field of production equipment for PE optical cable sheathing materials, in particular to a production line for PE optical cable sheathing materials. Background technique [0002] In the production process of PE optical cable sheath material, the two most critical links are the selection and proportion of raw materials and advanced production technology. These two links are also difficult points in production. The composition of recycled materials is more complex than that of new materials, and the molecular structure also has large fluctuations. The moisture content in raw materials is also relatively large and unevenly distributed. Moisture and small molecular substances concentrated in a certain section will cause air holes in this section of the cable, which will seriously affect product quality. This unstable factor is a quality problem that often occurs in the production of sheathing materials and is difficu...

Problems solved by technology

Over the years, this method cannot completely solve the above quality problems, but only reduces the probability of the above quality problems

In addition, it takes a long time to dry raw materials, consumes a lot of energy, and has low efficiency; the natural exhaust of the screw barrel has great limitations, and the removal is not complete. The harmful gas discharged permeates the workshop, causing pollution to the production environment and seriously affecting the health of employees. physical and mental health
