Description

Technical Field

[0001] The utility model belongs to the technical field of polymer material production, and particularly relates to a wide-format product carrier device in a plasticizing oven for wide-format products such as artificial leather and waterproof coiled materials. Background Art

[0002] Plasticizing ovens are essential equipment for manufacturing products such as PU / PVC artificial leather, PU synthetic leather, PVC flooring, PVC triple-proof tarpaulins, PVC anti-slip mats, PVC fabric coatings, laminated leather (split leather, transfer leather, or split leather), and latex sponges. Plasticizing ovens fall under the "Large-Scale and Precision Rubber and Plastic Processing Equipment" category, as defined in Section 4, "New Materials," Item (3), "Polymer Materials," and Article 6, "New Processing Applications and Application Technologies of Polymer Materials," of the National Key High-Tech Fields Supported by the State Council (National Science and Technology Development No. 32, 2016). The existing plasticizing oven frame is constructed and shipped as a single piece of steel. The insulation panels are filled with aluminum silicate fiber cotton, which easily shrinks due to vibration. This shrinkage creates space within the insulation panel cavity, affecting insulation effectiveness. During leather production line operation, due to the wide width of the product and the lack of any support devices at the bottom of the left and right sides, the leather products sag during production, impacting both efficiency and quality.

[0003] Although the existing leather production line uses a plasticizing oven for production, the carrier form of the existing oven is only suitable for PVC artificial leather, PU / PVC artificial leather, and PU synthetic leather, and the product width is 1500mm. With the advancement of science and technology, new products such as solvent-free artificial leather, silicone artificial leather, and PVC sports flooring have been gradually developed, and the product width has developed from 1500mm to 2000mm, 2300mm, and 3200mm. Therefore, a plasticizing oven wide-format product carrier device that can adapt to wide-format products is needed to prevent the leather products from sagging and improve the production efficiency and quality of leather.
