Description
Technical Field
[0001] This utility model relates to the field of laser film manufacturing technology, and in particular to a novel BOPP laser film manufacturing molding device. Background Technology
[0002] In the production process of BOPP laser film, the molding device is a key piece of equipment. Traditional molding devices often lack an effective dust removal mechanism during the transfer of laser film. Since the surface of the laser film easily attracts dust and impurities, these dust and impurities will affect the quality and effect of the laser film during the molding process, resulting in defects in the finished product. In addition, traditional molding devices often use mechanical brushes or air blowing to remove dust. Although these methods can remove some dust, they can easily scratch or damage the surface of the laser film, affecting the appearance and performance of the laser film.
[0003] Therefore, to address the aforementioned issues, a novel BOPP laser film molding device is proposed. This device uses electrostatic dust removal to adsorb and remove dust from the surface of the laser film, effectively improving the cleanliness and processing quality of the laser film. It avoids scratches or damage to the surface of the laser film caused by mechanical brushing or air blowing, thus ensuring the appearance and performance of the laser film. Utility Model Content

[0005] The technical solution of this utility model is as follows: A novel BOPP laser film molding device, comprising a platform, a first fixed frame, a dust removal component, a material guiding component, a preheating component, and a molding component.

The power supply energizes two sets of electrode tubes through wires, generating an electric field between the energized electrode tubes and the dust collection plates. This electric field between the two sets of dust collection plates adsorbs dust from the surface of the laser film, thus removing the dust. Pulling the handle moves the connecting plate linearly, allowing for quick removal and installation of the dust collection plates. This electrostatic dust removal prevents dust residue from affecting the laser film molding process and avoids contact with the laser film, thus improving the quality of the finished product.

[0022] Please see Figures 2-4 In this embodiment, the material guiding assembly includes a first support 201 and a second motor 202. The first support 201 is disposed above the platform 1, and the second motor 202 is disposed on one side of the first support 201.

The output end of the second motor 202 is disposed on the second rotating shaft 203, and the guide roller 204 is disposed on the outer side of the second rotating shaft 203. In use, the second motor 202 is started to drive the second rotating shaft 203 to rotate, and the rotation of the second rotating shaft 203 drives the guide roller 204 to rotate, thereby guiding and conveying the laser film through the rotation of the guide roller 204. The preheating assembly includes a second fixing frame 301 and a third motor 302. The platform 1 A second fixed frame 301 is provided above, and a third motor 302 is provided on one side of the second fixed frame 301. The preheating component also includes a third rotating shaft 303, a connecting roller 304, and an electric heating plate 305. The output end of the third motor 302 is provided with the third rotating shaft 303, and the connecting roller 304 is provided on the outer side of the third rotating shaft 303. The connecting roller 304 is provided above the platform 1, and the electric heating plate 305 is provided above the platform 1. In use, the third rotating shaft 303 is driven to rotate by starting the third motor 302, and the connecting roller 304 is driven to rotate by the rotation of the third rotating shaft 303. The laser film is transferred by the rotation of the connecting roller 304, and the laser film is preheated by starting the electric heating plate 305.
[0023] The molding assembly includes a first hydraulic rod 401 and a base plate 402. The first hydraulic rod 401 is positioned above the platform 1, and the base plate 402 is positioned above the first hydraulic rod 401. During use, the extension and retraction of the first hydraulic rod 401 drives the base plate 402 to move up and down, adjusting the height of the base plate 402. The molding assembly also includes a second hydraulic rod 403, a third fixing frame 404, a fourth motor 405, a fourth rotating shaft 406, and a molding roller 407. The second hydraulic rod 403 is positioned below the first fixing frame 2. One end of 03 is provided with a third fixed frame 404, a fourth motor 405 is provided on one side of the third fixed frame 404, a fourth rotating shaft 406 is provided at the output end of the fourth motor 405, and a molding roller 407 is provided on the outer side of the fourth rotating shaft 406. In use, the third fixed frame 404 is moved up and down by the telescopic movement of the second hydraulic rod 403. The fourth motor 405 is started to drive the fourth rotating shaft 406 to rotate. The rotation of the fourth rotating shaft 406 drives the molding roller 407 to rotate. The rotation of the molding roller 407 performs molding processing on the laser film.
[0024] During operation, the BOPP laser film is first placed on the material guide assembly, and the first motor 102 is started. The first motor 102 drives the first rotating shaft 103 to rotate, which in turn drives the conveying roller 104 to start rotating and transport the laser film. At the same time, the power supply 105 is started, and the two sets of electrode tubes 107 are energized through the wire 106. An electric field is formed between the electrode tubes 107 and the dust collection plate 110. This electric field electrostatically adsorbs the dust on the surface of the laser film during the transport process, firmly adsorbing the dust onto the dust collection plate 110. When the dust on the dust collection plate 110 accumulates to a certain extent, the handle 111 can be pulled to drive the connecting plate 108 to slide on the limiting tube 109, thereby quickly removing the dust collection plate 110 for cleaning or replacement. This step effectively removes the dust from the surface of the laser film and avoids the dust affecting the subsequent processing.
[0025] After dust removal, the laser film continues to be conveyed by the material guiding assembly. The second motor 202 is started, which drives the second rotating shaft 203 to rotate, driving the guide roller 204 to rotate, ensuring that the laser film moves forward smoothly and continuously. Then, the laser film enters the preheating assembly area, where the third motor 302 is started, which drives the third rotating shaft 303 to rotate, driving the connecting roller 304 to rotate. At the same time, the electric heating plate 305 is started to preheat the laser film. Preheating helps to improve the flexibility and plasticity of the laser film, preparing it for subsequent molding processing.
[0026] After preheating, the laser film enters the molding assembly area. First, the height of the base plate 402 is adjusted by the telescopic movement of the first hydraulic rod 401 to ensure a suitable gap between the molding roller 407 and the laser film. Then, the second hydraulic rod 403 is activated, driving the third fixed frame 404 to move up and down, bringing the molding roller 407 closer to the laser film. Next, the fourth motor 405 is activated, driving the fourth rotating shaft 406 to rotate, which in turn drives the molding roller 407 to perform molding processing on the laser film. During the molding process, the molding roller 407 imprints the preset pattern or texture onto the laser film, completing the production of the laser film. After processing, the molding roller 407 is lifted by the telescopic movement of the hydraulic rod, and the processed laser film is removed.
[0027] Through the above steps, the first motor 102 drives the first rotating shaft 103 to rotate, and the rotation of the first rotating shaft 103 drives the conveying roller 104 to rotate. The rotation of the conveying roller 104 can transfer the laser film. The power supply 105 uses wires 106 to energize the two sets of electrode tubes 107. The energization of the electrode tubes 107 and the dust collection plate 110 generate an electric field. The electric field between the two sets of dust collection plates 110 adsorbs the dust on the surface of the laser film and removes the dust from the surface of the laser film. The connecting plate 108 is moved linearly by pulling the handle 111. The linear movement of the connecting plate 108 can quickly remove and install the dust collection plate 110. This electrostatic dust removal prevents dust from remaining on the surface of the laser film and affecting the laser film molding process. The electrostatic dust removal method can also prevent contact with the laser film and damage, thus improving the quality of the finished laser film.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
