Description
Technical Field
The invention relates to an organ type pinch roller structure and a working method for a continuous fiber winding plastic composite pressure pipe production line, which can implement press bonding on winding plastic layers in different fiber surface states in the manufacturing and winding process of the composite pressure pipe, and belongs to the field of manufacturing of organ type pinch roller structures.
Background
The current continuous fiber composite pressure pipe is developed rapidly, and relates to a plurality of composite methods, a fiber belt which is subjected to resin pre-impregnation is wound and coated on the outer surface of a plastic solid pipe, and then a layer of plastic is coated on the surface of the fiber belt which is subjected to resin pre-impregnation, so that an inner layer plastic and an outer layer plastic are formed, and the fiber belt which is subjected to resin pre-impregnation is arranged between the middle layer. The anti-position strength of the resin is (6-10) MPa, and the tensile strength of the fiber tape of the prepreg resin is (600-900) MPa, which is remarkable. By compounding, plastic pipes with the same performance are produced, and the plastic is saved by (30-80)%. However, due to different composite production lines, different process routes are formed, layering is easy to occur between the composite plastic and the fiber tape of the presoaked resin, and the reliability of the product is reduced, so that the product cannot be popularized. The reason for the poor reliability is that: when the plastic is compounded with the fiber tape of the prepreg resin, the temperature of the fiber tape body of the prepreg resin cannot reach 160 ℃ or more as high as that of the plastic, and below the temperature, the plastic cannot be melted, and the fiber tape of the prepreg resin cannot be melted, so that effective adhesion cannot be realized. The reason why the temperature of the fiber band body of the prepreg resin cannot reach 160 degrees or more as high as that of plastic is that: the plastic pipe begins to melt when the temperature exceeds 160 ℃, the melted pipeline begins to be stretched under the action of the tractor, and the plastic pipe begins to collapse inwards while being stretched, so that the inner pipe is thoroughly damaged, and the production cannot be performed.
Disclosure of Invention
The design purpose is as follows: the organ type pinch roller structure for the continuous fiber winding plastic composite pressure pipe production line and the working method thereof are designed to avoid the defects in the background art, wherein the organ type pinch roller structure can be used for implementing press bonding and bonding on winding plastic layers with different fiber surface states in the manufacturing and winding process of the composite pressure pipe.
The design scheme is as follows: in order to achieve the above design objective. In structural design, the invention is characterized in that the inner layer and the outer layer of the wound plastic are tightly adhered to the steel drum mold by the pinch roller when the composite pipe is produced, so that the inner wall of the pipe is smooth and the outer surface layer has no concave-convex phenomenon. Therefore, an organ type pinch roller structure is specially designed, and the structure drives a speed reducer to rotate a gear rack to move a chassis to move back and forth on a linear guide rail by a servo motor. After the plastic layer is attached to the steel drum and the pressing wheel moves to the bottom of the steel drum mold, the cylinder starts to lift the movable frame to slide by the shaft, so that the pressing sheet is clung to the steel drum mold to rotate passively. Secondly, in order to ensure that the pressing piece can passively rotate, a sufficient gap is formed between the swing arm and the teflon piece (pressing piece) in structural design, the swing arm can move along the axis C, the tension is determined by a spring, and the convex surface of the steel drum die can be smoothly transited.
The technical scheme is as follows: an organ-type pinch roller structure is composed of a compressing sheet, a swinging arm, a shaft, a spring and a shaft B; the pressing pieces are positioned in the grooves of the heads of the swing arms, the swing arms provided with the pressing pieces are sequentially penetrated on the shafts by shaft holes to form an organ type pressing wheel piano face, the shafts and the shafts are fixed on the support A, the shafts B are positioned below the shafts, one ends of the springs are fixed on the shafts B, and the other ends of the springs are in clamping and spring fit with the grooves of the lower parts of the swing arms.
Compared with the background technology, the piano key with the organ type pinch roller structure can realize the press bonding of the plastic layer on the plane or the rugged surface of the melted plastic belt continuously, so that the plastic belt can be melted with the fiber belt of the presoaked resin to be effectively bonded.
