Problems solved by technology

[0005] 2. The positioning part is installed inside the coating mold. The problems of this structure are: first, if the positioning part is made of flexible material, when the profile passes through the positioning part, the profile will be pressed against the positioning part under its own gravity. On the part, the positioning part is deformed, resulting in a gap between the profile and the upper part of the positioning part, which cannot form a seal for the coating liquid. Obviously, the above-mentioned coating mold restricts the use of flexible materials for the positioning part structurally.
Secondly, if the positioning part is made of a material with high hardness, due to the tolerance of the extruded profile, when the size of the profile is larger than the size of the minimum cross section of the positioning part, the profile and the positioning part will interfere and cannot pass through the positioning part. ; or when the size of the profile is smaller than the size of the smallest cross-section of the positioning part, a gap is formed between the profile and the positioning part and the coating liquid cannot be sealed
[0006] 3. The coating mold with the above structure is inconvenient in assembly, cleaning and maintenance

Embodiment 1

[0022] Such as figure 1 and figure 2 , the polyurethane composite material pultrusion production line 1 of the present invention includes a box body 10 for the pultruded composite material A to pass through, a positioning component 20 for limiting the deflection of the pultruded composite material passing through the box body, and a composite The material applies a uniform coating film and forms a seal against the coating liquid. The elastic member 30 and the outer splint 40 undergo elastic deformation when subjected to squeezing force. The elastic member 30 is clamped between the outer splint 40 and the positioning member 20 . The positioning component 20 is positioned outside the box body 10, and the positioning component 20 is preferentially arranged at the exit position of the box body 10, and the elastic component 30 is positioned at the downstream of the positioning component 20, so that the elastic component 30 and the outer splint 40 are also downstream of the exit of...

Embodiment 2

[0039] Such as Figure 7 , the positioning component 20 is arranged inside the box body 10, and the positioning component 20 is integrally formed with the box body 10, and the positioning component 20 is a raised portion, and multiple such raised portions are preferably provided. Since the positioning component 20 is located inside the box body 10 , the elastic component 30 and the outer splint 40 are still disposed outside the box body 10 , and the outer splint 40 is connected to the box body 10 .

[0040] When the positioning part 20 is arranged inside the box body, the first stop arm 10d that controls the deformation of the elastic member is provided in the box body 10, the first stop arm 10d, and the first stop arm 10d is preferentially arranged on the inner wall of the box body 10 and The first blocking arm 10d is located near the outlet of the box body 10 . With this structure, the edge 31 of the elastic member 30 is clamped by the edge of the first clamping plate 41 an...

Embodiment 3

[0042] The positioning part 20 is a combination of Embodiment 1 and Embodiment 2, that is, a part of the positioning part 20 is arranged outside the box body 10 as in Embodiment 1, and another part of the positioning part 20 is arranged on the outside of the box body 10 as in Embodiment 2. internal. With this structure, there is no need to arrange the first stop arm 10d in the box body 1 , and a part of the deformation part 32 is clamped by the second stop arm 23 of the clamping part 44 .

[0043] In addition, the second frame-shaped component may also be in a non-closed state, for example, a notch is opened on the basis of the second frame-shaped component in the first embodiment above.

[0044] In addition, generally, the pultrusion die C is used for pultrusion of polyurethane composite materials, and the formed pultrusion composite material A is cooled by a cooling mechanism located downstream of the pultrusion die C, such as Figure 8 , on the basis of the above-mentioned...

Abstract

The invention discloses a polyurethane composite pultrusion production line. The polyurethane composite pultrusion production line comprises a pultrusion mold which is used for pultrusion of a polyurethane composite and a cooling mechanism which is located on the downstream of the pultrusion mold and further comprises at least one coating unit, the coating unit comprises an on-line coating mold which is used for performing on-line coating on the pultrusion composite and a switching mechanism which is used for driving the on-line coating mold to be in a working station or a non-working station;the on-line coating mold limits the fact that deflection of a pultrusion composite material which penetrates through a box body is generated and form a seal when a uniform coating film is applied tothe pultrusion composite material; and the switching mechanism is fixed with the on-line coating mold. The polyurethane composite pultrusion production line has the advantage of ensuring the sealing performance.

Description

technical field [0001] The invention relates to a polyurethane composite material pultrusion production line, which is used for online coating of the pultruded composite material formed into a predetermined shape. Background technique [0002] Polyurethane pultrusion composites have the problem of insufficient weather resistance, especially in long-term outdoor exposure, the resin layer on the surface is easy to pulverize, change color, and even expose fibers. Therefore, polyurethane pultrusion composites usually need to be coated. [0003] US5492583A discloses a method and device for online coating of pultruded composite materials. The method adds a coating die to the online coating of the pultrusion profile after the pultrusion die. The coating die has the ability to apply a uniform coating to the pultrusion parts. The apparatus, comprising a coating chamber where the coating is applied for the first time and a positioning part of the coating mold that holds the coating un...
