Embodiment 1

[0039] like figure 1 As shown, the outer cladding feeding mechanism of the FRPP three-layer wall reinforced pipe production equipment includes a laterally movable carriage 1, and the carriage 1 is provided with a horizontally facing and can be positioned with both ends of the tube blank 9 respectively. The movable die head 102, the fixed die head 2, the movable die head 26 and the fixed die head 27 can all be driven to rotate by a rotating motor.

[0040] Specifically, as Figure 1-5 As shown, one side of the carriage 1 is provided with an extruder 3, and the fixed touch head 2 includes a rotatable base 23 and a cylindrical support 22 connected to the base 23. The support 22 has an inner wall that can support the tube blank 9. The small-diameter end 22c and the large-diameter end 22b that can be placed on the outer cladding layer 101, the diameter of the large-diameter end 22b is larger than the diameter of the small-diameter end 22c, and the small-diameter end 22c is locate...

Embodiment 2

[0048] The content of this embodiment is basically the same as that of the first embodiment, and the difference lies in:

[0049] The support is a radially shrinkable mesh frame, and the mesh frame is connected to the jaws 21 a of the three-jaw chuck 21 .

[0050] The grid can be radially retracted with the movement of the jaws 21a, which can further improve the support for the outer cladding layer 101 and the tensioning and positioning of the tube blank 9.

Abstract

The invention provides an outer coating layer feeding mechanism of FRPP three-layer wall reinforced pipe production equipment, and belongs to the technical field of FRPP three-layer wall reinforced pipe production equipment. The problem that an outer coating layer of an existing three-layer-wall reinforced pipe is not uniform in coating is solved. The outer coating layer feeding mechanism of the FRPP three-layer wall reinforced pipe production equipment comprises a dragging plate capable of transversely moving, a movable die head and a fixed die head which directly face each other in the transverse direction and can be located with the two ends of a pipe blank respectively are arranged on the dragging plate, an extruder is arranged on one side of the dragging plate, and the fixed die head comprises a rotatable seat body and a cylindrical supporting piece connected to the seat body. The supporting piece is provided with a small-caliber end capable of supporting the inner wall of the pipe blank and a large-caliber end capable of containing the outer coating layer, the diameter of the large-caliber end is larger than that of the small-caliber end, and the small-caliber end is located at the end close to the movable die head. According to the outer coating layer feeding mechanism of the FRPP three-layer wall reinforced pipe production equipment, the feeding uniformity and stability of the outer coating layer are improved, and the feeding quality of the outer coating layer is further improved.

Description

technical field [0001] The invention belongs to the technical field of FRPP three-layer wall reinforced pipe production equipment, and relates to an outer cladding material feeding mechanism of the FRPP three-layer wall reinforced pipe production equipment. Background technique [0002] FRPP reinforced pipe is made of fiber reinforced polypropylene material, the inner wall is smooth and the outer wall is a special structure pipe with reinforcing ribs. Because the reinforcing ribs are I-beam structure, it is lighter in weight and stronger in strength than traditional solid wall pipes. High advantages, its superior performance and good cost performance make FRPP reinforced pipes widely used in urban construction drainage and sewage projects. [0003] But the existing FRPP reinforced pipe is divided into three layers, such as Figure 5 As shown, the RPP three-layer wall reinforced pipe includes a tube blank 9 , a fiber tape layer 10 and an outer cladding layer 101 . [0004] T...
