System for be used for PE tubular product processing

Technical Field

The invention belongs to the technical field of PE pipe processing, and particularly relates to a system for processing a PE pipe.

Background

The cable guide pipe is a commonly used protective pipe in cable laying in various places in recent years, and frequently adopted plastic pipes such as MPP, PE and the like have poor strength, cannot bear heavy pressure, are flammable and fragile, are not heat-resistant, are not anti-aging and have short service life. In order to enhance the strength of the pipe, in the existing pipe processing, a layer of glass fiber with resin is wound outside the pipe, and after the resin is solidified, the glass fiber and the resin form a protective layer together to enhance the strength of the pipe. However, in the processing process, due to the existence of the resin, a certain time is needed for the resin to be cooled and solidified, the time is long, and the working efficiency is low. And the adhesion degree between the glass fiber winding and the pipe is relatively poor, and the intensity on glass fiber layer is relatively poor, and when the pipe is drawn by sharp objects, the glass fiber layer often can be hung badly, and then leads to the pipe on inlayer to be scratched.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the system for processing the PE pipe, which has high working efficiency and strong scratch resistance of the prepared pipe.

In order to achieve the purpose, the invention adopts the following technical scheme: a system for processing a PE pipe comprises a pipe body and an outer layer coated outside the pipe body, wherein the pipe body is a PE pipe, and the outer layer is a glass fiber layer; the processing system comprises a support, a station rod capable of penetrating into the pipe body, a driving part arranged on the support and used for driving the station rod to rotate, an outer layer processing mechanism used for winding glass fibers outside the pipe body, a material taking frame used for taking the pipe body off the support and a drying mechanism used for drying the pipe body; the sliding seat is provided with a storage bin, the upper part of the storage bin is provided with an opening, the bottom of the storage bin is provided with a roller, and a gap is reserved between the roller and the bottom wall of the storage bin. According to the invention, by arranging the drying mechanism, the drying operation can be carried out on the processed pipe, so that the resin wound outside the pipe along with the glass fiber can be dried quickly, the drying and solidifying time of the resin is shortened, and the working efficiency is improved; the support frame is arranged, so that the pipe communicated with the station rod can be conveniently detached from the rack by directly adopting the support frame, and the station rod and the pipe are directly moved into the drying mechanism by conveying the support frame, so that the pipe is not required to be manually carried, the operation is labor-saving, and the working efficiency is high; the automatic winding of the glass fibers is realized through the equipment, so that the working efficiency is high, the glass fibers wound through the equipment are uniformly distributed, the thickness uniformity of the glass fiber layer is ensured, and the qualified rate of the processed pipe is high; can hold the resin in the storage silo, the clearance between roller bearing and the storage silo can supply glass fiber to pass to glass fiber will have the resin, and the adhesion between and the tubular product is stronger, and twine outside the tubular product and the intensity after solidifying is higher, and the whole fastness of the tubular product that processing obtained is good and difficult by wearing and tearing or scratch.
