Description

Technical Field

[0001] This utility model belongs to the field of thin film flattening technology, and in particular relates to an ETFE thin film flattening device. Background Technology

[0002] ETFE film, short for ethylene-tetrafluoroethylene copolymer film, is a high-performance fluoroplastic film copolymerized from ethylene and tetrafluoroethylene. Due to its excellent comprehensive properties, it is often referred to as soft glass. ETFE film flattening refers to the process of unfolding and flattening the ETFE film material using a specific method before processing and construction to eliminate wrinkles and creases and ensure its surface flatness. Flattening is a key step in the processing and application of ETFE film, and its main function is to ensure that the film can maintain a flat and wrinkle-free state in subsequent processes, thereby ensuring product quality, precision and production efficiency. However, the existing flattening devices are not easy to debug, so an ETFE film flattening device is proposed.

[0003] For example, Chinese patent CN214773964U discloses a film flattening device, belonging to the technical field of flattening devices. It includes a film feeding shaft, a pressure plate, a magnetic powder device, a patterned roller, a flattening roller, a flattening roller support, locking screws, a worm gear mechanism, a vertical plate, hexagonal head screws, a setter sleeve, and a support bracket. The support bracket is located at the bottom of the vertical plate. The patterned roller includes a patterned roller shaft and a patterned roller cylinder. Both ends of the patterned roller shaft are fixed to the top of the vertical plate by hexagonal head screws. The flattening roller support is located on the inner side of the vertical plate. The upper and lower ends of the flattening roller support are respectively provided with an upper support plate and a lower support plate. The surface of the upper support plate is provided with a worm gear mechanism, and the lower support plate is threadedly connected to the support bracket. By providing a film flattening device, the flattening roller shaft located between the two worm gears is subjected to equal extrusion force from both ends, causing it to bend upwards under pressure, continuously approaching the patterned roller until it abuts against the patterned roller, thus achieving a better film flattening effect.

[0004] The aforementioned patent has the following problems: Compared to existing technologies, the current technology is not simple to debug and is relatively complex to operate, requiring a considerable amount of time and effort from operators. This increases the workload and time required for operators. Furthermore, existing technologies do not use adhesive strips on the flattening rollers, making it difficult to adhere the film for flattening, which is inconvenient. Additionally, the adhesive strips are of poor quality and cannot guarantee durability, reducing the practicality of the device. Therefore, we propose an ETFE film flattening device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an ETFE film flattening device that is easy to debug and has adhesive strips on the flattening rollers.

[0006] In view of this, the present invention provides an ETFE film flattening device, including a protective cover, and further comprising: a roller body movably installed inside the protective cover, a limiting disk movably installed on both sides of the roller body, a shaft head movably installed on one side of the roller body, a keyway fixedly opened on the surface of the shaft head, an adhesive strip movably installed between the protective covers, a polyurethane layer fixedly disposed inside the adhesive strip, a rubber layer fixedly disposed inside the polyurethane layer, and transverse grooves fixedly opened on the surface of the adhesive strip.

[0007] Based on the above structure, the rubber strip can be fixed by the roller body and wrapped around its surface. Then, the limiting disc can limit and lock the roller body, facilitating the fixing of the protective cover and support to both sides of the roller body. Next, the shaft head is fixed to one side of the roller body. The shaft head, connected to the roller body, supports the rotation of the roller body, enabling it to withstand the load and torque during rotation. The shaft head is usually made of metal and comes in different shapes and sizes to suit different mechanical applications. Then, a keyway is created by machining a groove on the shaft and inside the hole to match the key, used to install the key and transmit torque. The system is simple to use and easy to adjust, reducing the workload and time required for operators. The rubber strip can be fixed to the surface of the roller body, and a polyurethane layer is then placed inside the rubber strip. The polyurethane layer possesses excellent wear resistance, oil resistance, and toughness. The rubber layer, with its high elasticity and wear resistance, further enhances the wear resistance of the rubber strip. The rubber strip is then embedded in the transverse grooves and extends above the roller body, forming a roller surface with the rubber strips arranged in a strip pattern. Both ends of the rubber strip are connected to outward-sloping handwheels on both sides of the roller body. As the rubber strip rotates with the roller body, it drives the handwheels to rotate, which in turn gradually pulls the rubber strip towards the shaft end. The rubber strip is gradually stretched from 0 degrees to 180 degrees, and then gradually retracts back to its original length from 180 degrees to 360 degrees. When the substrate rotates 180 degrees, the rubber strip can extend to both ends and flatten itself. In combination, the use of rubber strips on the roller body enables flattening operations. The high-quality rubber strip material ensures durability and increases the practicality of the device.

[0008] Preferably, a fixing plate is movably mounted on the surface of the protective cover, and screws are installed through the interior of each fixing plate. The fixing plate allows the protective cover to be opened.

[0009] Preferably, a support is movably installed between the limiting plates, and a support leg is fixedly installed at the bottom of each support. A mounting base is fixedly installed at the bottom of each support leg, and the support can support the device.

[0010] Preferably, sound-absorbing cotton is movably installed inside the roller body, which can reduce noise.

[0011] Preferably, a handle is fixedly installed on the surface of the support, and a rubber pad is fixedly provided on the surface of the handle, so that the device can be lifted by the handle.

[0012] Preferably, both ends of the sound insulation cotton are fixedly installed with fixing rods, and handwheels are fixedly installed on both sides of the fixing rods, which facilitate the rotation of the device.

[0013] Preferably, both ends of the screw have ventilation holes, and a dustproof mesh is fixedly installed inside the ventilation holes to allow ventilation.

[0014] The beneficial effects of this utility model are: 1. This ETFE film flattening device uses a roller to fix the adhesive strip, which is wrapped around the surface of the roller. Then, a limiting plate can limit and lock the roller, making it easy to fix the cover and support to both sides of the roller. Then, the shaft head is fixed to one side of the roller. The shaft head, through its connection with the roller, supports the rotation of the roller, enabling it to withstand the load and torque during rotation. The shaft head is usually made of metal and has different shapes and sizes to adapt to different mechanical applications. Then, a keyway is machined on the shaft and in the hole to match the key, which is used to install the key to transmit torque. The device is simple to use and easy to debug, and the operation is not complicated. The operator does not need to spend a long time debugging, reducing the workload and working time of the operator.

[0015] 2. This ETFE film flattening device utilizes adhesive strips fixed to the surface of a roller. A polyurethane layer is then placed inside the adhesive strip. The polyurethane layer provides excellent wear resistance, oil resistance, and toughness, while the rubber layer enhances the wear resistance of the adhesive strip by providing high elasticity and wear resistance. The adhesive strip is then embedded in transverse grooves and extends above the roller, forming a roller surface with the adhesive strips arranged in a strip pattern. Both ends of the adhesive strip are connected to outward-sloping handwheels on both sides of the roller. As the roller rotates, the adhesive strip drives the handwheels, which in turn gradually pull the adhesive strip towards the shaft end. The adhesive strip is gradually stretched from 0 degrees to 180 degrees, and then gradually retracts to its original length from 180 degrees to 360 degrees. When the substrate rotates 180 degrees, the adhesive strip can extend to both ends and flatten the film. In combination, the use of adhesive strips on the roller enables flattening operations. The high-quality adhesive strip material ensures durability and increases the practicality of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This application discloses an ETFE film flattening device. Please refer to [link / reference]. Figures 1-5 The device includes a protective cover 1, and further includes: a roller body 2 movably installed inside the protective cover 1, a limit plate 201 movably installed on both sides of the roller body 2, a shaft head 202 movably installed on one side of the roller body 2, a keyway 203 fixedly opened on the surface of the shaft head 202, a rubber strip 3 movably installed between the protective cover 1, a polyurethane layer 301 fixedly disposed inside the rubber strip 3, a rubber layer 302 fixedly disposed inside the polyurethane layer 301, and transverse grooves 303 fixedly opened on the surface of the rubber strip 3.

[0020] Based on the above structure, the rubber strip 3 can be fixed and wrapped around the surface of the roller body 2 using the roller body 2. Then, the limiting plate 201 can limit and lock the roller body 2, making it convenient for the protective cover 1 and the support 4 to be fixed to both sides of the roller body 2. Then, the shaft head 202 is fixed to one side of the roller body 2. The shaft head 202 supports the rotation of the roller body 2 by connecting with the roller body 2, enabling it to withstand the load and torque during rotation. The shaft head 202 is usually made of metal and has different shapes and sizes to adapt to different mechanical applications.

The rubber strip 3 can be fixed to the surface of the roller body 2, and then the polyurethane layer 301 is set inside the rubber strip 3. The urethane layer 301 has excellent wear resistance, oil resistance, and toughness. The rubber layer 302, with its high elasticity and wear resistance, enhances the wear resistance of the rubber strip 3. The rubber strip 3 is then embedded in the transverse groove 303 and extends above the roller body 2 to form a roller surface with the rubber strip 3 arranged in a row. The two ends of the rubber strip 3 are connected to outwardly inclined handwheels 701 on both sides of the roller body 2. When the rubber strip 3 rotates with the roller body 2, it drives the handwheels 701 to rotate, and the handwheels 701 gradually pull the rubber strip 3 towards the shaft end. When the rubber strip 3 rotates from 0 degrees to 180 degrees, it is gradually stretched to its maximum length. When it rotates from 180 degrees to 360 degrees, it gradually shrinks back to its original length. When the substrate rotates to 180 degrees, the rubber strip 3 can extend to both ends and be flattened. In combination, the use of rubber strip 3 on the roller body 2 enables flattening. The high-quality material of the rubber strip 3 ensures durability and increases the practicality of the device.

The two ends of the rubber strip 3 are connected to outwardly inclined handwheels 701 on both sides of the roller body 2. When the rubber strip 3 rotates with the roller body 2, it drives the handwheels 701 to rotate, which in turn gradually pulls the rubber strip 3 towards the shaft end.
