Description

Technical Field

[0001] The utility model belongs to the technical field of removing a stripping cloth from the surface of a pultruded plate, and particularly relates to an anti-damage device for removing a stripping cloth from the surface of a pultruded plate. Background Art

[0002] During the production of composite pultrusion sheets, a layer of release cloth is added to the surface to enhance the surface roughness. The release cloth will be torn off during operation. Figure 1 As shown, the existing equipment is equipped with a reel at the top and bottom to roll and collect the torn release cloth. Since it is a mechanical operation, the pultruded sheet moves on the runway at a fast speed. When the release cloth is torn off the sheet, the force is uneven and the tearing angle is too large, which easily causes surface tearing and causes the pultruded sheet to be scrapped. Therefore, there is an urgent need for an anti-damage device for removing the release cloth from the surface of the pultruded sheet to solve the above problems. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide an anti-damage device for removing the release cloth from the surface of pultruded plate.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0005] A damage prevention device for removing a demoulding cloth from the surface of a pultruded sheet, comprising a frame mounted at the outlet of an unwinder, the frame being equipped with three sets of guide rollers, on which pultruded sheets slide, the frame being equipped with reeling wheels on the upper and lower sides of the unwinder outlet, and the frame being further equipped with an auxiliary tooling and a demoulding tooling, the auxiliary tooling being arranged near the outlet of the unwinder, and the demoulding tooling being arranged on a side away from the outlet of the unwinder;

[0006] The auxiliary tooling includes clamping plates arranged on the upper and lower sides of the pultruded sheet, with sufficient space between the clamping plates for the pultruded sheet and the demoulding cloth;

[0007] The demoulding tooling includes demoulding clamps arranged on the upper and lower sides of the pultruded plate, one side of the demoulding clamp is provided with an oblique cut, and buckles are also installed on the left and right sides of the demoulding clamps on the upper and lower sides.

[0008] Furthermore, the clamping plates are provided with threaded holes on both sides, wherein bolts are connected to the threaded holes, and the bolts are mounted on the frame. This structural design allows the clamping plates on both sides to be adjusted up and down, thereby pushing the torn release sheet to a nearly parallel state with the pultruded sheet.

[0009] It is further defined that the mold removal clamping plate is tightly engaged with the pultruded sheet through a buckle. Such a structural design ensures that the pultruded sheet will not jump when it moves.

[0010] It is further defined that the buckle is arranged in an E-shaped structure. Such a structural design is convenient for clamping the mold removal clamping plate and limiting its installation.

[0011] It is further defined that the shapes of the clamping plate and the mold removal clamping plate can be selected from a cuboid, a cube, or a cylinder. Such a structural design allows the shapes of the clamping plates to be selected in a variety of styles so as to be more suitable for work use.

[0012] The beneficial effects of the present invention are as follows: by arranging auxiliary tooling and demoulding tooling, the present invention prevents the pultruded sheet from jumping up and down when moving at high speed, and the speed runs well, and no surface damage occurs when the demoulding cloth is torn off the pultruded sheet, thereby effectively preventing the loss of the sheet.

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1, as Figure 2 and Figure 3As shown, an anti-damage device for removing the demoulding cloth from the surface of a pultruded sheet is installed on a frame. Three sets of guide roller groups 1 are installed on which a pultruded sheet 2 slides. The frame is equipped with reeling wheels 3 on the upper and lower sides of the unwinder outlet. An auxiliary tooling 4 and a demoulding tooling 5 are also installed on the frame. The auxiliary tooling 4 is arranged near the unwinder outlet, and the demoulding tooling 5 is arranged on the side away from the unwinder outlet.

[0023] The auxiliary tooling 4 includes clamping plates 6 provided on the upper and lower sides of the pultruded sheet 2, with sufficient space between the upper and lower clamping plates 6 for the pultruded sheet and the demoulding cloth;

[0024] The demoulding tool 5 includes demoulding clamps 7 arranged on the upper and lower sides of the pultruded plate 2. A bevel cut 8 is provided on one side of the demoulding clamp 7. Buckles 9 are also installed on the left and right sides of the upper and lower demoulding clamps 7.

[0025] In this embodiment, during use, the position of the splint 6 is first controlled to leave enough space between the pultruded sheet 2 and the demoulding cloth. Then the pultruded sheet 2 slides through the three sets of guide roller groups 1 and passes through the auxiliary tooling 4 and the demoulding tooling 5 in turn. When the pultruded sheet 2 passes through the demoulding tooling 5, the demoulding cloth on the pultruded sheet 2 passes through the demoulding splint 7 and follows the oblique cut 8. It passes through the upper part of the demoulding splint 7 and then passes through the lower part of the splint 6 and is rolled into the corresponding winding wheel 3 to be tightened and fixed, thereby completing the work of removing the demoulding cloth. The demoulding cloth on the lower surface of the pultruded sheet 2 is operated in the same way as the demoulding cloth on the upper surface.

[0026] Example 2, as Figure 3 and Figure 5 As shown, this embodiment adds the following structure on the basis of embodiment 1: threaded holes 10 are provided on both sides of the clamping plate 6, and bolts 11 are connected in the threaded holes 10, and the bolts 11 are set on the frame.

[0027] In this embodiment, the upper and lower clamps 6 are fixed by connecting threaded holes 10 with bolts 11, leaving enough space for the pultruded sheet 2 and the demoulding cloth in the middle, and the clamps 6 can also be adjusted up and down, thereby pushing the torn demoulding cloth to a state close to parallel with the pultruded sheet 2.

[0028] Example 3, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1, and the mold removal clamping plate 7 is tightly fitted with the pultruded plate 2 through the buckle 9.

[0029] In this embodiment, the demoulding clamping plate 7 is tightly fitted to the pultruded sheet 2 via the buckle 9, ensuring that the pultruded sheet 2 does not jump when moving.

[0030] Example 4, as Figure 4As shown, this embodiment adds the following structure on the basis of embodiment 1, and the buckle 9 is arranged in an E-shaped structure.

[0031] In this embodiment, the upper and lower mold removal clamps 7 can be clamped by the clips 9 arranged in an E-shaped structure, so that the mold removal clamps 7 can be tightly fitted with the pultruded plate 2.

[0032] Example 5, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure on the basis of embodiment 1. The shapes of the clamping plate 6 and the demoulding clamping plate 7 can be selected from rectangular parallelepiped, cube, and cylinder.

[0033] In this embodiment, the shapes of the clamping plate 6 and the mold removal clamping plate 7 can be selected as a rectangular parallelepiped, a cube, a cylinder, etc. according to actual usage conditions, so as to be more suitable for work.
