Description

Technical Field

[0001] The utility model relates to the technical field of pre-coated films, and specifically, to a stability ironing device for pre-coated films. Background Art

[0002] Currently, during the production process of tapes, glue is often applied to the pre-coated film and then dried. However, due to factors such as manufacturer production, loading and unloading during loading and unloading, or vibration during transportation, the pre-coated films produced by existing manufacturers often form numerous small wrinkles, resulting in uneven surface tension of the pre-coated film. This causes uneven thickness after coating the pre-coated film, leading to poor product quality, a large number of defective products and losses. It not only increases the production cost of the product, but also the formed waste products are difficult to degrade, causing environmental pollution. Currently, ironing devices are usually used to iron the pre-coated film to make its surface flat and smooth.

[0003] After retrieval, the existing patent (publication number: CN205130370U) discloses a BOPP pre-coated film ironing device, which includes an unwinding device, a steam drying cylinder, and a traction roller. The unwinding device, the steam drying cylinder, and the traction roller are arranged in sequence from left to right. A tension roller is also provided between the unwinding device and the steam drying cylinder. The unwinding device is used to unwind the BOPP pre-coated film, the traction roller pulls the BOPP pre-coated film at the front end, the tension roller keeps the BOPP pre-coated film under tension during the forward movement, and the steam drying cylinder is used to iron the BOPP pre-coated film. A cooling roller is provided between the steam drying cylinder and the traction roller, and the cooling roller can cool the ironed BOPP pre-coated film to prevent the ironed BOPP pre-coated film from deforming again at high temperatures. The provided BOPP pre-coated film ironing device can iron the wrinkled BOPP pre-coated film, ensure that the gluing surface is flat and smooth, greatly reduce the generation of defective products, effectively reduce the production cost, reduce the generation of waste, and avoid environmental pollution.

[0004] However, it is found that the following problems exist in the implementation of the related technology: the position of the tension roller that keeps the pre-coated film under tension during the forward movement is fixed and non-adjustable. Due to reasons such as equipment operation vibration, the pre-coated film may be too tight or too loose during transportation. Being too tight is likely to cause the pre-coated film to break, and being too loose is likely to cause the pre-coated film to wrinkle. And the position of the tension roller is fixed and non-adjustable, resulting in the inability to adjust the tension roller to make the pre-coated film generate a safe and appropriate tension. Summary of the Utility Model

Among them, during the process of the pre-coated film being conveyed from the unwinding device 9 to the steam drying cylinder 10, according to the actual tightness state of the pre-coated film, by starting the electric cylinder 2, the installation frame 4 and the tension roller 5 can be lifted and lowered through the connecting plate 3. The tension maintained by the pre-coated film will also change during the lifting and lowering process of the tension roller 5 until the tension roller 5 is adjusted to a suitable height position to make the pre-coated film maintain a safe and appropriate tension, thereby preventing the pre-coated film from being too tight and prone to breakage due to excessive tension or too loose and prone to wrinkles due to too small tension. Moreover, the angle adjustment mechanism 7 can adjust the angular position of the electric cylinder 2, and then the electric cylinder 2 pushes the tension roller 5 to move into contact with the pre-coated film and generate a suitable tension, thereby realizing the change of the position of the tension roller 5 on the pre-coated film. The position of the tension roller 5 on the pre-coated film can be conveniently adjusted according to actual needs to achieve a suitable tension, which is particularly suitable for the use process of the tension roller 5 for different pre-coated films, and solves the problem that the position of the tension roller 5 in the related technology cannot be adjusted, resulting in the inability to adjust the tension generated by the tension roller 5 on the pre-coated film.
