Description

Technical Field

[0001] This utility model relates to the technical field of release paper coating composite device, specifically a wrinkle-resistant release paper coating composite device. Background Technology

[0002] Composite coating refers to a spray coating composed of two or more different materials. It uses a combination of various surface treatment technologies to improve the coating's protective ability against the substrate. After the composite coating film is applied to the release paper surface, it needs to be bonded to the release paper surface through a hot pressing process. After hot pressing, the temperature of the fabric surface is relatively high. If it is directly wound up, the temperature inside the release paper roll is likely to be too high, resulting in poor adhesion and stability of the coating film. At the same time, wrinkles are likely to occur when the product is wound.

[0003] A search revealed a patent with publication number CN213198826U, which discloses a wrinkle-resistant release paper coating laminating device. The device includes a base, a coating laminating box fixedly welded to the left side of the top of the base, a heating roller movably connected to the center of the inner cavity of the feeding trough, a first bracket fixedly welded to the center of the top of the base, a fixed shaft penetrating the top of the front of the first bracket, a rotating roller fitted around the outer ring of the fixed shaft, a fan on the top of the placement platform, a second bracket and a third bracket fixedly connected to the right side of the first bracket, both with fixed shafts penetrating the top of their front sides, a fourth bracket fixedly connected to the right side of the top of the base, a winding roller penetrating the top of the front of the fourth bracket, and a rotating shaft fixedly connected to the front of the winding roller. The fan on the placement platform dissipates heat as the coated material passes through the rotating roller, creating an upward airflow that cools the paper.

[0004] In the aforementioned prior art, the fan can only disperse the rising airflow on the coating surface. For the inside of the coating and the bottom surface in contact with the rotating roller, the heat is difficult to dissipate quickly, resulting in low cooling efficiency. When the release paper is wound up, the temperature inside the roll is still too high. This cannot completely solve the problem of poor adhesion and stability of the coating film. Furthermore, the temperature difference between the upper and lower surfaces can easily cause the release paper to warp and increase the risk of wrinkles during winding. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or existing anti-wrinkle release paper coating composite devices, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A wrinkle-resistant release paper coating composite device includes a mounting plate, a pressing mechanism on the mounting plate, a vertical frame on the mounting plate, a transmission roller and a pressing roller rotatably mounted on the vertical frame, a motor on one side of the vertical frame, and the output end of the motor connected to the transmission roller, and a cooling pressing mechanism on the mounting plate.

[0008] As a preferred embodiment of the anti-wrinkle release paper coating composite device of this utility model, the cooling and pressing mechanism includes a vertical plate mounted on a mounting plate. Two sets of tension rollers arranged in a circular array are provided on one side of the outer wall of the vertical plate. A fan is also symmetrically arranged on one side of the outer wall of the vertical plate, and the fan is located between the tension rollers arranged in a circular array. A fan is symmetrically arranged on the other side of the outer wall of the vertical plate, and the fan is connected to the fan. The outer wall of the fan has evenly distributed connecting holes.

[0009] As a preferred embodiment of the anti-wrinkle release paper coating composite device described in this utility model, the release paper is in the form of a letter and passes through a cooling and pressing mechanism.

[0010] As a preferred embodiment of the anti-wrinkle release paper coating composite device of this utility model, a number of directional rollers are provided on one side of the outer wall of the mounting plate, and the number of directional rollers are distributed in a trapezoidal array.

[0011] As a preferred embodiment of the anti-wrinkle release paper coating composite device of this utility model, the air duct is provided with evenly distributed partitions.

[0012] As a preferred embodiment of the anti-wrinkle release paper coating composite device of this utility model, an isolation cylinder is provided on the outer wall of the partition.

[0013] As a preferred embodiment of the anti-wrinkle release paper coating composite device of this utility model, the outer wall of the air duct is provided with uniformly distributed extensions, and the outer wall of the extensions is provided with uniformly distributed air holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this scheme, the release paper is transported in a T-shape under the guidance of the directional roller and the tension roller, so that its upper and lower surfaces alternately contact the air duct and the extension section. The cooling airflow generated by the fan is evenly distributed by the baffle and isolation cylinder in the air duct, and then blown to the upper and lower surfaces of the release paper through the air holes of the extension section, quickly removing heat and avoiding excessive temperature difference between the upper and lower surfaces of the release paper, which would cause warping. This improves the cooling efficiency and uniformity. In this solution, the tensioning roller applies continuous tension to the release paper, and with the guidance of the directional roller, the release paper remains flat during transport, eliminating wrinkles caused by uneven tension. In this design, the baffles and isolation cylinders inside the air duct divide the space inside the air duct into several areas, so that the cooling airflow delivered by the fan is evenly distributed inside the air duct, and then blown evenly onto the release paper through the air holes of the extension section, thus avoiding the problem of uneven cooling caused by excessively strong or weak local airflow.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Example Please see Figures 1-4 This utility model provides a technical solution: A wrinkle-resistant release paper coating composite device can achieve efficient and uniform cooling of the release paper after hot pressing, while fully aligning the release paper to avoid excessive temperature and wrinkles during winding, thereby improving the adhesion and stability of the coating film.

[0021] The wrinkle-resistant release paper coating laminating device includes a mounting plate 1, which is a rectangular metal plate serving as the mounting base for the device. A pressing mechanism 2 is installed on the mounting plate 1 for hot-pressing the release paper and the coating film. A stand 3 is welded onto the mounting plate 1. The stand 3 is a symmetrical metal frame on both sides. A drive roller 5 and a squeeze roller 4 are rotatably mounted on the stand 3 via bearings. The drive roller 5 and the squeeze roller 4 cooperate with each other to convey the release paper. A motor 6 is fixed to one side of the stand 3 by bolts. The output end of the motor 6 is connected to the drive roller 5 via a coupling to provide power for the rotation of the drive roller 5.

[0022] The mounting plate 1 is provided with a cooling and pressing mechanism 7, which is used to cool and press the release paper after hot pressing. The cooling and pressing mechanism 7 includes a vertical plate 8 welded to the mounting plate 1. The vertical plate 8 is a rectangular metal plate. Two sets of tension rollers 12, each arranged in a circular array, are provided on one side of the outer wall of the vertical plate 8. The tension rollers 12 are cylindrical rubber rollers used to tension the release paper.

[0023] A cylindrical metal duct 10 is symmetrically arranged on one side of the outer wall of the vertical plate 8. The duct 10 is positioned between tension rollers 12 arranged in a circular array and is used to cool the release paper. A centrifugal fan 9 is symmetrically fixed to the other side of the outer wall of the vertical plate 8 via bolts. The outlet of the fan 9 is connected to the duct 10 via a pipe, providing cooling airflow to the duct 10. Evenly distributed connecting holes 15 are provided on the outer wall of the duct 10 for airflow. Evenly distributed partitions 17, made of metal plates, are welded inside the duct 10. Isolation cylinders 16 are welded to the outer walls of the partitions 17. 6 is a cylindrical metal tube that divides the internal space of the air duct 10 into several independent areas to improve the uniformity of air circulation. The outer wall of the air duct 10 is connected to evenly distributed extensions 11. The extensions 11 are tapered metal tubes that shorten the distance with the release paper and improve the heat dissipation effect. The outer wall of the extensions 11 is provided with evenly distributed air holes 14 for blowing the cooling airflow toward the release paper. Several directional rollers 13 are welded to one side of the outer wall of the mounting plate 1. The directional rollers 13 are cylindrical metal rollers and are arranged in a trapezoidal array to guide the transmission direction of the release paper so that the release paper passes through the cooling and pressing mechanism 7 in a figure-eight shape.

[0024] Guided by the directional roller 13 and tension roller 12, the release paper is transported in a figure-eight pattern, allowing the upper and lower surfaces of the release paper to alternately contact the air duct 10 and the extension section 11. The cooling airflow generated by the fan 9 is evenly distributed through the baffle 17 and isolation cylinder 16 inside the air duct 10, and then blown onto the upper and lower surfaces of the release paper through the air holes 14 of the extension section 11, quickly removing heat from the inside and surface of the release paper, preventing excessive temperature difference between the upper and lower surfaces from causing warping, and improving cooling efficiency and uniformity. The tension roller 12... The release paper is subjected to continuous tension, which, combined with the guidance of the directional roller 13, keeps the release paper flat during the transmission process, eliminating wrinkles caused by uneven tension during transmission. The baffle 17 and the isolation cylinder 16 inside the air duct 10 divide the space inside the air duct 10 into several independent areas, so that the cooling airflow delivered by the fan 9 can be evenly distributed inside the air duct 10, and then evenly blown onto the release paper through the air holes 14 of the extension 11, avoiding uneven cooling caused by local airflow being too strong or too weak.

[0025] In use, first start the pressing mechanism 2, motor 6, and fan 9. The pressing mechanism 2 is preheated to a suitable hot pressing temperature. Motor 6 drives the transmission roller 5 to rotate, and the transmission roller 5 drives the extrusion roller 4 to rotate synchronously. The cooling airflow generated by the fan 9 is transported to the air duct 10 through the pipe. Under the guidance of the directional roller 13, the release paper first passes through the first set of tension rollers 12, approaches from one side between the two sets of tension rollers 12, goes around to the lower side of the first set of tension rollers 12, and then passes over the upper side of the second set of tension rollers 12 below, forming an 8-shaped transmission trajectory. Then it extends between the transmission roller 5 and the extrusion roller 4. During the transmission process, the release paper is first tightly bonded to the coating film under the hot pressing action of the pressing mechanism 2, and then passes through the lowering... The initial cooling and pressing of the temperature-pressing and aligning mechanism 7 involves tensioning the release paper with tension roller 12 to keep it flat and prevent wrinkles. At the same time, the cooling airflow in the air duct 10 is evenly distributed under the action of partition plate 17 and isolation cylinder 16, and blown onto the surface of the release paper through the air hole 14 of the extension 11. Since the release paper is wrapped in a figure-eight shape, its back side, which was originally on the first air duct 10, becomes the inner side when passing through the second air duct 10, so that both the upper and lower surfaces of the release paper can be fully cooled and the heat dissipation is more uniform. After cooling and pressing, the release paper enters between the drive roller 5 and the extrusion roller 4. Finally, the cooled release paper is neatly wound up by the winding mechanism (not shown in the figure), completing the entire lamination, cooling and winding process.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
