Technical Field

Background

In the existing wood board processing, in order to obtain a better appearance effect, PVC decorative films are generally adhered to the surfaces of two sides of a solid wood board or a composite board, so that an attractive board product is formed. In order to improve the production efficiency, a laminating machine with higher automation degree is generally adopted for production at present in the wood board laminating production process.

At present, a plurality of types of automatic plate laminating machines are available in the market, for example, a double-sided laminating machine with Chinese patent publication No. CN108407453A, and the positioning precision is improved by arranging a positioning mechanism; through the specially designed lower film frame and the specially designed upper film frame, unnecessary troubles in the process of replacing the film roll are reduced, the replacement time is shortened, and the replacement efficiency is improved; meanwhile, the distance between the pressing roller and the film covering platform in the pressing mechanism can be adjusted through a threaded rod and a spring, so that the use performance of the double-sided film covering machine is improved, and the double-sided film covering machine is suitable for film covering work of components with different thicknesses; a series of improvements really greatly improve the product quality and the production efficiency, but have no good solution for wood boards with different width specifications, and can only be suitable for large-scale plate film-coating production.

A sheet laminating machine with the Chinese patent publication No. CN105922709A is characterized in that a sensor is additionally arranged in a sheet conveying line body to detect the position of a sheet and the laminating length, so that the start and the end of laminating are automatically judged, and a cutting blade automatically judges the position of a gap so as to cut a product after laminating, so that the full utilization of a film is realized, and the use of a raw material film is saved to a certain extent. However, in the face of the continuously changing board size required in the current production, only the reasonable cutting in the length direction can be achieved, and the cutting in the width direction is lacked, so that the simultaneous generation requirement of the boards with multiple specifications cannot be met.

An automatic wood board surface film covering machine disclosed in the Chinese patent publication No. CN209095753U mainly solves the problem of centralized feeding of wood boards in the same batch, and aims at wood boards of different specifications, the machine needs to be stopped first, and then the distance between two baffles is adjusted, so that the automatic wood board surface film covering machine can meet the requirements of wood boards of different sizes.

The market condition is comprehensively researched, and the automatic film laminating machine of the current plate is specially designed and improved only aiming at the large-scale production of plates with the same specification, so that the production efficiency is improved, and the plate can only be used as a raw material plate. However, at present, furniture manufacturers receive a large number of customized products, particularly door panel products, and the size and the specification are different according to different application scenes of customers, under the condition, the pre-cut original wood board is coated with films, and the requirements of the film coating production of boards with different specifications can be met only by continuously adjusting a baffle plate and a raw material film of a film coating machine, so that the production continuity is greatly influenced, and the production efficiency is also influenced.

Therefore, for the film-coating production of customized boards with multiple dimensions, it is necessary to develop a full-automatic film-coating machine to meet the film-coating production requirements of boards with different dimensions.
