The release film is used as a base, and the polyurethane solvent is evenly applied on the release film. The PET original film covers the polyurethane solvent. The three-layer structure enters the oven together and is foamed into a foam material through the high-temperature polyurethane solvent. After leaving the oven, the PET original film is combined with the foam material, and the release film can be separated from the foam material. The winding mechanism separates the release film from the foam material, and the release film is wound up separately, while the PET original film is wound up together with the foam material.

[0006] 2. The rotation of the upper pressure roller provides the main driving force for the material to move forward, which can easily cause the separation and rubbing of the PET original film and the foaming material, resulting in horizontal stripes on the surface, and folding, slipping and deformation of the release film;

[0007] 3. The material is not positioned and is prone to deviation, resulting in uneven winding of the release film and the foaming material. Utility Model Content

[0038] See also Figures 2 to 5 The utility model of the winding device for continuous production of foam coils comprises a pressure roller assembly 2, a first winding roller assembly 6, a second winding roller assembly 7, a first winding frame 10 and a second winding frame 11 arranged along the traction direction of the foam coil. The pressure roller assembly 2 is arranged on the positioning traction frame 1, and a positioning pressing mechanism is arranged at the end of the pressure roller assembly 2. The first winding roller assembly 6 and the second winding roller assembly 7 are provided with a pressing gap adjustment cylinder 8 and a power motor 9 at the ends.

[0039] In the preferred embodiment shown in the accompanying drawings, the positioning and pressing mechanism includes a positioning and pressing cylinder 3 and a positioning gap adjustment structure 4. The piston end of the positioning and pressing cylinder 3 is provided with a first wedge block, and the first wedge block is connected to the end of the lower pressure roller in the pressure roller assembly 2; the positioning gap adjustment structure 4 is arranged corresponding to the first wedge block, and the positioning gap adjustment structure 4 includes a connecting piece, a bolt, and a second wedge block; wherein the bolt passes through the connecting piece and is connected to the positioning and traction frame 1 through the connecting piece, and a second wedge block is provided at its end; the second wedge block is arranged below the first wedge block, and the wedge surfaces of the two match. The second wedge block is driven to move along the wedge surface by the rotation of the bolt, so as to adjust the distance between the two pressure rollers of the pressure roller assembly 2. The utility model can make the upper and lower pressure rollers of the pressure roller assembly 2 lightly pressed together by the positioning and pressing cylinder 3, position the foam coil passing between the upper and lower pressure rollers, and then adjust the gap by the positioning gap adjustment structure 4.

[0040] In other embodiments, the gap adjustment of the rollers can be achieved by arranging a gap adjustment cylinder at the end of the roller assembly 2. The gap adjustment cylinder can not only realize the relative movement of the upper and lower rollers in the roller assembly 2 and position the foam roll passing between the upper and lower rollers, but also realize the adjustment of the gap between the rollers. The principle of the gap adjustment cylinder is a prior art and will not be described in detail here.

[0041] The pressing roller assembly on the positioning and traction frame of the utility model can play a role in positioning the material so that it will not deviate during traction under the joint action of the positioning pressing cylinder and the positioning gap adjustment structure, and can also ensure that the whole material will not be damaged by hard pressing, and the material can be flexibly rolled up without damaging the material structure and appearance, thereby causing abnormal quality waste.

[0042] Furthermore, the first winding roller assembly 6 and the second winding roller assembly 7 are arranged on the winding roller frame 5, and the two winding roller assemblies are respectively provided with winding frames, which are used to wind up the separated release film and the foaming material with the PET original film.

[0043] The first winding roller assembly 6 and the second winding roller assembly 7 are provided with a pressing gap adjustment cylinder 8 at the end thereof, which can adjust the gap between the two pressing rollers to ensure the smooth separation of the release film and the foaming material with the PET original film, and at the same time ensure that the material is flatly rolled without deformation, which is conducive to the neat rolling of the material; and the first winding roller assembly 6 and the second winding roller assembly 7 are provided with a corresponding power motor 9 at the end thereof, which is used to provide power for the rolling. The pressing gap adjustment cylinder 8 is provided correspondingly to the upper pressing roller or the lower pressing roller of the first winding roller assembly 6 and the second winding roller assembly 7, and the power motor 9 is provided correspondingly to the other pressing roller, that is, the lower pressing roller or the upper pressing roller.

The lamination gap adjusting cylinder is used to adjust the pressure roller gap, and the lower pressure roller is driven to rotate under the action of the power motor, thereby driving the coil to move.

[0045] The release film and the foaming material with the PET original film that have passed through the first winding roller assembly 6 and the second winding roller assembly 7 are wound up by the first winding frame 10 and the second winding frame 11. In the embodiment shown in the drawings, the coiled material of the first winding roller assembly 6 is wound up by the first winding frame 10, and the coiled material of the second winding roller assembly 7 is wound up by the second winding frame 11. One of the first winding frame 10 and the second winding frame 11 is used to wind up the release film, and the other is used to wind up the foaming material with the PET original film.

[0046] The utility model arranges the power motor for pulling the coiled material at the winding roller assembly, rather than at the pressing cylinder, and arranges the power motor after the release film and the foaming material with the PET original film are separated, so as to avoid forcibly using external force to make the two have a speed difference when the release film is not completely separated, thereby generating a distance difference, causing the PET original film and the foaming material to separate and rub, and the release film to be folded, slipped and deformed. Through the above arrangement, the foaming material with the PET original film can be rolled up smoothly, so that the PET original film can be reused.

[0047] It is understandable that, in order to improve the separation effect of the release film and the foaming material with the PET original film, corresponding rollers are also provided in the release film traction path and the foaming material traction path with the PET original film of the pressure roller assembly 2 and the first winding roller assembly 6 and the second winding roller assembly 7. Of course, other rollers can also be provided in the traction path of the coiled material according to the specific film penetration situation.

[0048] It can also be understood that, in the foam material production process, the rollers, pressure rollers and winding rollers are arranged in parallel.

[0049] Taking the implementation shown in the accompanying drawings as an example, Figure 5 As shown, the utility model is a winding device for continuous production of foam coils. The coil passes through the pressure roller assembly 2 and is positioned under the pressure of the positioning and pressing cylinder 3. The gap of the pressure roller of the pressure roller assembly 2 is adjusted by adjusting the bolts of the positioning gap adjustment structure 4; the gap of the winding rollers is adjusted by the pressing gap adjustment cylinder 8 of the first winding roller assembly 6 and the second winding roller assembly 7; the power motor 9 on the first winding roller assembly 6 and the second winding roller assembly 7 drives the pressure roller to rotate, respectively providing power for the advancement of the release film and the foaming material with the PET original film, and the release film or the foaming material with the PET original film is respectively wound up by the first winding frame 10 and the second winding frame 11.
