Description

Technical Field

[0001] This application relates to the field of embossing equipment technology, and in particular to a film embossing device for fiberglass sheets. Background Technology

[0002] Film embossing is a processing technique that uses physical pressure (usually combined with heat) to create permanent, raised, or recessed textured patterns on the surface of a plastic film. Its core purpose is to give the film specific functional or decorative effects.

[0003] The prior art, disclosed in patent application CN218985747U, describes a composite laminating machine. In this patent application, an insulation layer is placed above the heating roller to prevent heat loss during lamination, allowing the finishing rollers to better flatten the hot-pressed composite film. However, in this prior art patent application, the insulation layer is only placed above the heating roller in the area opposite the film. This causes a faster rate of heat loss from the bottom of the heating roller, leading to increased heating energy consumption in the embossing equipment and hindering energy conservation. Utility Model Content

[0004] In order to improve the problem of the rapid heat loss from the bottom area of ​​the heating roller, which leads to increased heating energy consumption in the embossing equipment and is not conducive to energy saving, this application provides a film embossing equipment for fiberglass sheets.

[0005] The technical solution of the film embossing equipment for fiberglass sheets provided in this application is as follows: A film embossing device for fiberglass sheets, comprising: The frame serves as a support structure for the embossing equipment; A heating element is disposed on the frame and has an area that can be attached to the film to heat the film. The insulation component includes a film module connected to the frame and sleeved on the heating component, with the film located between the insulation component and the heating component. A feed inlet is provided on the insulation component, and the film can be wrapped around the heating component through the feed inlet; The discharge port is located on the heat insulation component, and the heated film can leave the heat insulation component through the discharge port. An embossing assembly is disposed downstream of the heating member and is capable of performing embossing operations on the film.

[0006] By adopting the above technical solution, during the film embossing process, the film is wound around the heating element through the feed port, heated by the heating element, and then enters the embossing assembly through the discharge port. The embossing assembly performs the embossing operation on the film. By using the insulation component to cover the heating element, the insulation component can keep the heating element warm all around. Compared with the prior art, which only insulates the part opposite to the film, this application can slow down the heat loss rate of the heating element, reduce the heating energy consumption in the embossing equipment, and is more conducive to energy conservation and environmental protection.

[0007] Preferably, the heat insulation component is provided with a heating element, which is arranged along the circumference of the heat insulation component.

[0008] By adopting the above technical solution, during the film embossing process, the heating element is arranged circumferentially along the heat insulation component, which can heat and keep the heating element warm around its perimeter, improve the film heating and softening effect, and thus improve the film embossing effect.

[0009] Preferably, the heat preservation component includes an upper heat preservation cover and a lower heat preservation cover, with the inlet and outlet formed between the ends of the upper heat preservation cover and the lower heat preservation cover, and the upper heat preservation cover is disposed opposite to the film wrapped on the heating member.

[0010] By adopting the above technical solution, the upper and lower insulation covers of the insulation component work together to form an inlet and an outlet. The upper insulation cover is opposite to the film, which can focus on the insulation of the area where the heating component is attached to the film, further improving the insulation effect of the heating component and more effectively reducing heating energy consumption.

[0011] Preferably, the upper insulation cover includes a fixed cover and a movable cover, the movable cover being hinged to the frame so that the upper insulation cover can be opened.

[0012] By adopting the above technical solution, the upper insulation cover consists of a fixed cover and a movable cover that can be rotated and opened around the hinge point of the frame, which facilitates the maintenance, repair and replacement of heating components and films, and improves the maintainability of the equipment.

[0013] Preferably, the frame is provided with a linear drive mechanism, which is hinged to the frame and has its other end hinged to the movable cover, so as to drive the movable cover to rotate around the hinge point with the frame.

[0014] By adopting the above technical solution, the movable cover can be driven to rotate around the hinge point with the frame by means of a linear drive mechanism, which makes it easy to open the upper insulation cover and facilitates the inspection, cleaning or replacement of parts of the heating components and the interior.

[0015] Preferably, the embossing assembly includes a lower pressure roller and a bearing roller, both of which are rotatably mounted on the frame. The film can flow between the lower pressure roller and the bearing roller, and the lower pressure roller can press the film onto the bearing roller to create a pattern on the film.

[0016] By adopting the above technical solution, the film can be pressed together by the lower pressure roller and the bearing pressure roller, and patterns can be made on the film to realize the embossing operation of the film.

[0017] Preferably, the lower pressure roller is provided with a rubber layer that contacts the film; the frame is provided with a cooling component that can cool the rubber layer.

[0018] By adopting the above technical solution, during the film embossing process, the rubber layer of the lower pressure roller contacts the film, and the cooling component cools the rubber layer to prevent the rubber layer from softening due to excessive temperature. This allows the rubber layer to stably press the film onto the pressure roller, thereby ensuring the embossing quality of the film.

[0019] Preferably, the assembly further includes a flattening roller rotatably mounted on the frame, the flattening roller being located downstream of the embossing assembly, the flattening roller having two spiral grooves with opposite directions of rotation, each spiral groove being spirally arranged along the axial direction of the flattening roller, the flattening roller being able to apply a tension force to the film along the axial direction of the flattening roller through each spiral groove, the two tension forces being in opposite directions.

[0020] By adopting the above technical solution, after the film is embossed by the embossing component, the two spiral grooves on the flattening roller with opposite directions can apply axial tension in opposite directions to the film, so that the film is flattened on the flattening roller, reducing film wrinkles and improving the flatness of the film surface.

[0021] Preferably, the two spiral grooves are symmetrically arranged about the midpoint of the flattening roller; the pitch of the spiral grooves gradually increases from the center of the flattening roller to the end.

[0022] By adopting the above technical solution, the symmetrically arranged spiral grooves can make the tension applied to the film in opposite directions more uniform, and the pitch gradually increases from the center of the flattening roller to the end, which can better adapt to the tension changes of the film during the flattening process and further improve the flattening effect of the film.

[0023] Preferably, it also includes an electrostatic elimination component: the electrostatic elimination component includes an ion fan and a wire assembly, the ion fan is capable of blowing ion wind toward the film, and the wire assembly is in contact with the film and grounded to provide a path for charge discharge.

[0024] By adopting the above technical solution, during the film embossing process, the ion blower blows ion air towards the film, and the wire assembly contacts the film and is grounded, providing a discharge path for the charge on the film, effectively eliminating static electricity on the film, and reducing the impact of static electricity on the embossing operation and subsequent processing.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The insulation component is fitted over the heating component, which insulates the heating component from all sides. Compared with the prior art, which only insulates the part opposite to the film, this application can slow down the heat loss rate of the heating component, reduce the heating energy consumption in the embossing equipment, and is more conducive to energy conservation and environmental protection. 2. After the film is embossed by the embossing assembly, the two spiral grooves on the flattening roller that rotate in opposite directions can apply axial tension in opposite directions to the film, so that the film is flattened on the flattening roller, reducing film wrinkles and improving the flatness of the film surface. 3. The rubber layer is cooled by a cooling device to prevent it from softening due to excessive temperature. This ensures that the rubber layer can stably press the film onto the pressure roller, thereby guaranteeing the embossing quality of the film. 4. Using an ion blower to blow ion air onto the film, the conductor group contacts the film and is grounded, providing a discharge path for the charge on the film, effectively eliminating static electricity on the film and reducing the impact of static electricity on the embossing operation and subsequent processing.

[0035] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0036] This application discloses a film embossing device for fiberglass sheets.

[0037] Reference Figure 1 , Figure 2 A film embossing device for fiberglass sheets includes a frame 1, a heating component 2, a heat insulation component 3, a feed inlet 41, a discharge outlet 42, an embossing component 5, a flattening roller 6, and an electrostatic elimination component 7.

[0038] The frame 1 is divided into several modules to support the equipment at various positions on the embossing equipment production line.

[0039] Reference Figure 3 , Figure 4In this embodiment, the heating component 2 is a rotating heating cylinder 21. Both ends of the heating cylinder 21 are rotatably connected to the frame 1 through a rotating shaft 22, and the heating cylinder 21 is driven to rotate by a motor mounted on the frame 1. In this embodiment, the heating cylinder 21 is heated by an oil bath. Two rotating shafts 22 are coaxially and fixedly connected to the heating cylinder 21. One rotating shaft 22 has an oil inlet channel 23 communicating with the heating cylinder 21, and the other rotating shaft 22 has an oil return channel 24 communicating with the heating cylinder 21. The oil inlet pipe 25 of the oil bath circulation system is connected to the oil inlet channel 23 through a rotary joint, realizing the rotational connection between the rotating shaft 22 and the oil inlet pipe 25. The oil return pipe 26 of the oil bath circulation system is connected to the oil return channel 24 through a rotary joint, making the oil return pipe 26 rotatably connected to the rotating shaft 22. The hot oil of the oil bath circulation system enters the heating cylinder 21 through the oil inlet pipe 25 and the oil inlet channel 23 to heat the heating cylinder 21. The hot oil after heat exchange flows back to the oil bath circulation system through the oil return channel 24 and the oil return pipe 26. The oil bath circulation system heats the hot oil, realizing the circulating oil bath heating of the heating cylinder 21.

[0040] Reference Figure 3 , Figure 5 In this embodiment, the heat preservation component 3 includes an upper heat preservation cover 31 and a lower heat preservation cover 32. Both the upper heat preservation cover 31 and the lower heat preservation cover 32 are arc-shaped plate structures. The length of both the upper heat preservation cover 31 and the lower heat preservation cover 32 is greater than the length of the heating cylinder 21. The two ends of the upper heat preservation cover 31 and the two ends of the lower heat preservation cover 32 respectively form a feed inlet 41 and a discharge outlet 42, such that the upper heat preservation cover 31 is located above the feed inlet 41 and the discharge outlet 42, and the lower heat preservation cover 32 is located below the feed inlet 41 and the discharge outlet 42. The frame 1 is rotatably connected to guide rollers 33 at both the feed inlet 41 and the discharge outlet 42. The guide rollers 33 are located below the middle horizontal plane of the heating cylinder 21. The film is wrapped around the heating cylinder 21 by the guide rollers 33 at the feed inlet 41, and then detached from the heating cylinder 21 by the guide rollers 33 at the discharge outlet 42. By guiding the film through the two guide rollers 33, the stability of the film's adhesion to the peripheral wall of the heating cylinder 21 can be improved, and the effect of the heating cylinder 21 on heating and softening the film can be improved.

[0041] The upper insulation cover 31 and the film wound on the heating cylinder 21 are positioned opposite each other. Heating elements 34 are provided on the sides of the upper and lower insulation covers 31 and the heating cylinder 21, respectively. In this embodiment, the heating elements 34 are several electric heating rods 341, which are arranged circumferentially on the upper and lower insulation covers 31 and 32 of the heating cylinder 21. The upper and lower insulation covers 31 and 32 provide circumferential insulation for the heating cylinder 21. Compared to the prior art method of only insulating the top of the heating cylinder 21, this application can slow down the heat loss rate of the heating components 2, reduce the heating energy consumption in the embossing equipment, and is more conducive to energy conservation and environmental protection. Heating both sides of the film through the electric heating rods 341 and the heating cylinder 21 can improve the softening effect of the film, resulting in clearer embossing and a better embossing effect.

[0042] Reference Figure 1 , Figure 5 The upper insulation cover 31 includes a fixed cover body 311 and a movable cover body 312. The fixed cover body 311 is fixedly connected to the frame 1, and one end of the movable cover body 312 is hinged to the frame 1 through a hinge structure. The frame 1 is provided with two sets of linear drive mechanisms 313, which are respectively arranged on both sides of the movable cover body 312. In this embodiment, the linear drive mechanism 313 is a hydraulic cylinder 3131. The cylinder body of the hydraulic cylinder 3131 is hinged to the frame 1, and the piston rod of the hydraulic cylinder 3131 is hinged to the movable cover body 312. The extension and retraction of the hydraulic cylinder 3131 drives the movable cover body 312 to rotate around the hinge point with the frame 1, thereby realizing the opening and closing of the upper insulation cover 31. The linear drive mechanism 313 drives the movable cover body 312 to rotate around the hinge point with the frame 1, which facilitates the opening of the upper insulation cover 31 and facilitates the inspection, cleaning, or replacement of parts of the heating component 2 and its interior.

[0043] Reference Figure 5 , Figure 6 In this embodiment, the embossing assembly 5 includes a lower pressure roller 51 and a bearing roller 52. The bearing roller 52 is engraved with patterns. Both ends of the bearing roller 52 are coaxially fixedly connected to rotating shafts 511. Each rotating shaft 511 is rotatably connected to the frame 1 through a bearing. Both rotating shafts 511 are provided with coaxially arranged connecting channels. The cooling water system is connected to one of the connecting channels through an inlet pipe and a rotary joint. The other connecting channel is connected to the cooling water circulation system through a rotary joint and an outlet pipe, so that the cooling water circulation system can pass cooling water into the bearing roller 52 to cool and reduce the temperature of the bearing roller 52. At the same time as the film embossing is completed, the film is cooled and shaped, which improves the embossing quality.

[0044] Reference Figure 5 , Figure 6The lower pressure roller 51 is positioned above the bearing roller 52. Both ends of the lower pressure roller 51 are rotatably connected to the lifting mechanism 512 mounted on the frame 1 via bearings. The lifting mechanism 512 can be driven by a linear hydraulic cylinder, which drives the lower pressure roller 51 to move up and down, adjusting its position. A rubber layer 513 is wrapped around the periphery of the lower pressure roller 51, pressing the film firmly onto the bearing roller 52 to achieve stable embossing. A cooling chamber is provided inside the lower pressure roller 51, with both ends connected to a cooling water circulation system via rotary joints and pipes, allowing cooling water to enter the cooling chamber inside the lower pressure roller 51 and cool the rubber layer 513.

[0045] Reference Figure 6 , Figure 7 A cooling component 53 is fixedly installed on the frame 1. In this embodiment, the cooling component 53 includes a fan 531 and an air duct 532. The air duct 532 is fixedly installed above the lower pressure roller 51 and is arranged along the axial direction of the lower pressure roller 51. The air duct 532 is connected to the fan 531. The air duct 532 is provided with several air outlets facing the rubber layer 513. The air outlets are evenly arranged along the length direction of the air duct 532. The fan 531 blows cold air to the rubber layer 513 through the air duct 532 and the air outlets to cool the rubber layer 513 and prevent the rubber layer 513 from softening due to excessive temperature. This allows the rubber layer 513 to stably press the film onto the pressure roller 52, thereby ensuring the embossing quality of the film.

[0046] Reference Figure 7 In this embodiment, the static elimination component 7 includes an ion fan 71 and a wire group 72. The ion fan 71 is located downstream of the lower pressure roller 51. The ion fan 71 is arranged along the width direction of the film and blows ion wind toward the film to neutralize the charge on the surface of the film.

[0047] Reference Figure 7In this embodiment, there are two flattening rollers 6, which are spaced apart along the film movement direction. Both flattening rollers 6 are located downstream of the ion blower 71. Both ends of the flattening rollers 6 are rotatably connected to the frame 1 and driven by a motor. The film passing through the ion blower 71 passes under the flattening rollers 6. Two spiral grooves 61 with opposite directions are formed on the flattening rollers 6. Each spiral groove 61 is spirally arranged along the axial direction of the flattening roller 6. The two spiral grooves 61 are symmetrically arranged about the midpoint of the flattening roller 6, which is located at the center of the film. The pitch of the spiral grooves 61 gradually increases from the center to the ends of the flattening roller 6. By adjusting the rotation direction of the motor, the flattening rollers 6 generate a pulling force on the film to both sides due to the spiral grooves 61, stretching the film areas corresponding to the two spiral grooves 61 to both sides, thus flattening the film on the flattening rollers 6, reducing film wrinkles, and improving the flatness of the film surface. By utilizing the spiral groove 61, the pitch gradually increases from the center to the end of the flattening roller 6, which can better adapt to the tension changes of the film during the flattening process and further improve the flattening effect of the film.

[0048] Reference Figure 7 , Figure 8 The lead wire assembly 72 is disposed on the winding mechanism at the end. In this embodiment, the lead wire assembly 72 includes a main wire 721 and multiple brushes 722. The main wire 721 spans the film along the width of the film and is grounded. The brushes 722 are connected to the main wire 721 and are evenly spaced along the length of the portion of the main wire 721 above the film. Each brush 722 is in contact with the film. The lead wire assembly 72 is in contact with the film and grounded, providing a discharge path for the charge on the film, effectively eliminating static electricity on the film, and reducing the impact of static electricity on the embossing operation and subsequent processing.

[0049] The implementation principle of the film embossing equipment for fiberglass sheets according to this application embodiment is as follows: The film embossing equipment uses a frame 1 to support various components, a heating component 2 to heat the film, and an insulation component 3 formed by an upper insulation cover 31 and a lower insulation cover 32 to slow down heat loss from the heating component 2 and reduce heating energy consumption. The inlet 41 and outlet 42 ensure smooth film entry and exit. The embossing component 5 performs the embossing operation on the heated film, the flattening roller 6 flattens the embossed film, and the static elimination component 7 eliminates static electricity on the film surface. The entire equipment has a reasonable structural design, with tight cooperation between various components, improving the quality and efficiency of film embossing while achieving energy saving and environmental protection.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
