In the process of producing steel belt reinforced polyethylene spiral corrugated pipe, it is necessary to carry out plastic coating process on the steel belt reinforced polyethylene spiral corrugated pipe. At present, the plastic coating machines on the market can only coat the surface of the corrugated pipe with plastic at one time, but cannot The inner wall and surface of the bellows are coated with plastic at the same time, and the plastic coating is uneven and the plastic coating effect is poor

The invention discloses a double-layer plastic-coating machine for a steel-strip-reinforced polyethylene helical bellows. The plastic-coating machine comprises a base and a control device, the control device is arranged on the top of the base, a first supporting plate is arranged at one side of the control device, a first plastic fluid box is arranged between the control device and the first supporting plate, a first transporting pipe is arranged at one side of the first plastic fluid box, and a first booster pump is arranged in the cavity of the first transporting pipe. According to the double-layer plastic-coating machine for the steel-strip-reinforced polyethylene helical bellows, a conveying belt with arc-shaped nylon brushes is arranged so that plastic coating of the surface of the helical bellows can be evener in the process of rotary plastic coating; a rotary disc is arranged so that a hydraulic rod can rotate under the effect of a motor in the forward propelling process, and therefore plastic coating of the inner wall of the helical bellows is evener; a restraining piece is arranged to fix the transporting pipe so that the conditions of breaking away or winding of the transporting pipe caused by rotating of the hydraulic rod can be avoided; and a movable roller used for winding the transporting pipe is arranged so that the condition of winding of the transporting pipe caused by rotating of the disc can be avoided.
Description
technical field [0001] The invention relates to the technical field of plastic coating processing, in particular to a double-layer steel belt reinforced polyethylene spiral corrugated pipe plastic coating machine. Background technique [0002] Steel belt reinforced polyethylene spiral corrugated pipe refers to high-density polyethylene (PE) as the matrix, the steel belt coated with adhesive resin on the surface is formed into a corrugated form as the main support structure, and is wound and compounded with polyethylene material to form a whole. Wall spiral bellows. In the process of producing steel belt reinforced polyethylene spiral corrugated pipe, it is necessary to carry out plastic coating process on the steel belt reinforced polyethylene spiral corrugated pipe. At present, the plastic coating machines on the market can only coat the surface of the corrugated pipe with plastic at one time, but cannot The inner wall and surface of the bellows are coated with plastic at ...
