Description

Technical Field

[0001] The utility model relates to the technical field of pallet production, in particular to a pallet coil double-sided laminating machine. Background Art

[0002] The laminating process is to coat the plastic film with adhesive, and then combine it with the sheet material after being pressurized by a rubber roller to form a product that combines sheet and plastic. The laminated product has a thin and transparent plastic film on the surface, which plays a protective role such as waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant, thus avoiding damage to the product surface. The existing laminating processes include instant laminating machines and pre-coating laminating machines. The instant laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is currently the most widely used laminating equipment in China. The pre-coating laminating machine has no gluing and drying parts, low cost, flexible and convenient operation, and is not only suitable for large-scale laminating processing, but also for small-batch and scattered product laminating processing, and has a promising future. However, no matter which laminating machine is used, it can generally only be laminated on one side in the current industry. If the product needs to be laminated on the reverse side after laminating, the single-sided laminated product needs to be turned over and then conveyed into the laminating machine, which is more labor-intensive and time-consuming, and has low processing efficiency. In response to the above problems, people invented patent number: CN201310063580.4, which discloses a double-sided laminating machine, which is a pre-coating laminating device. The material plate is conveyed through a conveyor table. When passing through the upper and lower pressing rollers, the film material with a bonding surface processed is pressed on the upper and lower surfaces of the material plate, reducing the process of turning the material plate over and then laminating, thereby improving production efficiency; but the double-sided laminating machine still has the following problems: 1. During double-sided lamination, due to the small spacing between the two layers of film material, the two layers of film material are attracted to each other at the inlet and stick together due to the electrostatic force or external force of the film material, affecting the subsequent laminating process; 2. The shaft rollers of existing double-sided laminating machines are mostly of fixed specifications and cannot be quickly adjusted according to the size of the coil. The applicability is low, and it is necessary to customize shaft rollers of different specifications to position the material and the subsequent positioning during the laminating action, which increases the cost.
