Description
Technical Field
The invention relates to the field of plate treatment, in particular to equipment and a method for surface treatment of a wood plate.
Background
In order to improve the antifouling and moisture-proof properties of various wood boards (such as a reconstituted wood board, a technical wood board and a raw wood board) and improve the brightness of the boards, a high-gloss film layer (such as a PET film layer) is generally coated on the surface of the boards. The prior art generally adopts hot melt adhesive or UV adhesive to bond the highlight film layer and the plate. The energy consumption of the hot melt adhesive layer is high, and the high-temperature treatment has great influence on the performance of the plate, so that the UV adhesive is increasingly adopted to carry out bonding treatment on the plate. In order to improve the adhesion effect of the UV glue on the plate, the plate itself needs to be subjected to surface treatment such as polishing and dust removal, so that a plane with certain roughness and uniformity is formed on the surface of the plate and serves as a bonding site of the UV glue. Of these surface treatments, the most important is a sanding treatment. A conventional sanding machine, as shown generally in fig. 1, comprises a plurality of parallel rolls, the surfaces of which are covered with a sanding belt or sand paper, and a pressing structure is provided above the rolls to press the plate against the rolls for sanding. However, the pressure of the pressing structure of the sanding device is difficult to adjust, the plate is easy to deform and warp due to excessive pressure, and the sanding device is difficult to be universally used for treating plates with different thicknesses.

The purpose of the invention is realized by the following technical scheme: the equipment for surface treatment of the wood board comprises a first driving mechanism, a second driving mechanism and at least one group of sanding roller sets; the sanding wheel set comprises a first sanding roller and a second sanding roller, the axis of the first sanding roller and the axis of the second sanding roller are located on the same level, a first driving mechanism drives the first sanding roller to rotate around the axis, a second driving mechanism drives the second sanding roller to rotate around the axis, and the surface speed of the second sanding roller is lower than that of the first sanding roller.
In the invention, the first driving mechanism and the second driving mechanism can be realized by using the existing motors, such as brushless motors and the like, and comprise necessary modules for controlling the rotating speed, necessary variable speeds (such as belts and reduction gear boxes) and transmission mechanisms for being in transmission connection with the sanding roller group. The first sanding roller and the second sanding roller can be realized by any one of the prior arts, such as rubber covered rollers with sanding belts. In the invention, the first sanding roller and the second sanding roller can rotate in the same direction or in different directions. Because the absolute surface speeds of the first sanding roller and the second sanding roller are different, when a plate without initial speed is freely placed on the first sanding roller and the second sanding roller, the advancing speed of the plate is different from that of the first sanding roller and that of the second sanding roller, and the plate cannot be as fast as any sanding roller, so that sliding friction is formed between the plate and the contact surface of the plate and sanding and polishing are completed. The speed difference of the two sanding rollers can be adjusted according to the requirement of sanding precision, and the larger the speed difference is, the larger the friction force is, the larger the sanding force is; for equipment requiring heavy sanding, the two sanding rollers should be counter-rotated. A plurality of sanding roller sets can be formed on one equipment, and each set is connected through the transmission band to the realization is to the polishing of panel different degree. According to the invention, by arranging the sanding roller sets with different internal rotating speeds, on the premise of not needing a clamping mechanism or exerting any pressure on the plate, enough friction force is generated between the plate and the sanding roller to finish sanding, the influence of the addition of the pressing mechanism on the shape and the strength of the plate in the prior art is effectively avoided, and meanwhile, the sanding force can be accurately controlled by controlling the rotating speed difference, so that the sanding quality is improved. Because the clamping mechanism is not arranged, the universality of the equipment is also improved, the equipment can be suitable for processing plates with any thickness without modification, the cost for producing new types of products is effectively reduced, and the market value is higher. In the invention, the plate material moves to the second sanding roller along the first sanding roller.
Preferably, the diameter of the second sanding roller is larger than that of the first sanding roller.
For a light plate, the diameter of the second sanding roller can be larger than that of the first sanding roller, so that the traveling resistance of the plate is increased by utilizing the gravity of the plate, and the friction force between the plate and the first sanding roller is further increased.
Preferably, the first sanding roller and the second sanding roller have the same turning direction and the same diameter
Preferably, the sanding machine further comprises 2 support plates arranged in parallel, horizontal strip-shaped through holes are formed in the support plates, and bearings are arranged at two ends of the first sanding roller and two ends of the second sanding roller respectively and movably arranged in the strip-shaped through holes.
