Problems solved by technology

[0005] The purpose of the present invention is: there is no production line dedicated to the preparation of double-layer ribbed two-color composite pipe strips at present, and it is easier to directly use the uncooled strip extruded from the extrusion die for the roll forming of composite pipes The inner cavity of the strip collapses or the rib deforms, which is not conducive to the technical problem of the use of the composite pipe. A double-layer ribbed double-color composite pipe strip production line and processing method are provided.

Embodiment 1

[0039] like Figure 1-5As shown, the double-layer ribbed double-color composite pipe strip production line includes batching machine 1, extrusion equipment 2 and sizing cooling device 3 connected in sequence, and the outlet of the sizing cooling device 3 is detachably connected to the pipe forming mechanism , the extrusion equipment 2 is provided with a forming channel 21 for forming the strip 6, the forming channel 21 is matched with the shape of the strip 6, the sizing cooling device 3 includes a box body 31, and the inside of the box body 31 A cooling channel 32 is provided, the section of the cooling channel 32 matches the shape of the strip 6 , and the cooling channel 32 communicates with the forming channel 21 .

[0040] The double-layer ribbed two-color composite pipe strip production line of this embodiment is composed of a strip production line by setting batching machine 1, extrusion equipment 2 and sizing cooling device 3 which are detachably connected in sequence, ...

Embodiment 2

[0045] like Figure 1-7 As shown, the double-layer ribbed two-color composite pipe strip production line of this embodiment has the same structure as that of Embodiment 1, the difference is that it also includes a traction mechanism 7 for pulling the strip 6 through the cooling channel 32, and the traction mechanism 7 can The disassembled one is located at the outlet of the sizing cooling device 32 . According to the actual situation, the traction mechanism 7 can be set to pull the strip 6 through the cooling channel 32, so that the strip 6 can be transported along the cooling channel 32. At the exit of the cooling channel 32, the finished strip 6 can be directly collected or directly transported into the pipe for forming. The use of the structure further facilitates the use of the strip 6. The production line with this structure can not only be used to produce double-layer ribbed two-color composite pipe strips, but also can be used to produce double-layer two-color composite...

Embodiment 3

[0049] like Figure 1-8 As shown, the processing method for strip processing using the above-mentioned strip production line of the present embodiment includes the following steps:

[0050] Step 1: batching: preparing raw materials for preparing strips, the raw materials are made of polyethylene materials; step 2: melting raw materials: heating and melting the raw materials in step 1. Step 3: extrusion molding: input the melted raw material in step 2 into the molding channel for extrusion molding; step 4: sizing cooling: input the strip extruded in step 3 into a sizing cooling device for cooling and shaping.

[0051] In the processing method of this embodiment, since the raw material is cooled and shaped after being extruded, the temperature of the strip output from the production line is relatively low, and it is not easily affected by the external environment such as gravity. It is directly used in the preparation of pipes, and the processing method of strips is relatively ...

Abstract

The invention relates to a manufacturing method of a composite pipe band, in particular to a double-layer ribbing two-color composite pipe band production line and a machining method thereof. The double-layer ribbing two-color composite pipe band production line comprises a burdening machine, extrusion equipment and a sizing cooling device that are sequentially connected; and an outlet of the sizing cooling device is detachably connected with a pipe forming mechanism. The double-layer ribbing two-color composite pipe band production line is simple in structure and the input and output modes are single. During machining, simply by inputting calculated amounts of raw materials to the burdening machine, a band output by the production line can be directly warehoused or input to a pipe forming mechanism for use, so that the manufacturing of the band is easier, and the band can be used to manufacture a pipe conveniently; in addition, since the sizing cooling device is arranged between the extrusion equipment and the pipe forming mechanism, the band output from the extrusion equipment is pre-cooled, a situation that interior cavity collapse or reinforcing rib deformation is generated due to the fact that the high-temperature band output from the extrusion equipment is affected by external environment factors like the gravity is avoided, and the band manufactured by the production line meets the use requirements.

Description

technical field [0001] The invention relates to a preparation method of a composite pipe and strip, in particular to a production line and a processing method for a double-layer ribbed two-color composite pipe and strip. Background technique [0002] Double-layer ribbed two-color composite pipe is a commonly used pipe in sewer pipes and drainage systems. It is mainly formed by winding and side welding polyethylene strips with internal cavities or reinforcing ribs. The strips are mainly made of melted plastic materials. The extrusion die is extruded, and the strip output from the extrusion die is generally directly input into the forming device used to roll and form the composite pipe. [0003] At present, there is no production line dedicated to the preparation of double-layer ribbed and two-color composite pipe strips, and the temperature of the strips extruded from the extrusion die is relatively high, and the strips are directly used for the roll forming of the composite ...
