The invention relates to a use instruction of a multilayer board preparation device, which comprises the following steps of firstly placing a bottom layer board 1 on a placing frame 3. The adhesive is poured into the interior of the paint cartridge 51 and the operation of the heating plate 52 is controlled so that the adhesive is always in a liquid state for subsequent application. The hydraulic cylinder 17 is controlled to operate, and oil is conveyed to the second hydraulic cylinder 17 through the oil passage 16, so that the T-shaped frame 19 is relatively moved. At this time, the intermediate plate is placed on the T-shaped frame 19, and the plate 1 is supported by the T-shaped frame 19, so that the subsequent application of the adhesive is facilitated.
The first bi-directional motor 60 is controlled to operate to drive the corresponding gear 56 to rotate. The roller 54 is driven to move in parallel on the paint cartridge 51 by rotation of the two gears 56 on the rack 53, and at this time, the paint cotton 55 rolls in the paint cartridge 51, thereby applying the adhesive to the bottom of the board 1. In the process, the first bi-directional motor 60 is moved in parallel on the paint cartridge 51 by sliding the guide rail 58 in the guide groove 57. When the first bi-directional motor 60 is moved to the extreme end, the first bi-directional motor is controlled to rotate reversely, so that each part is reset. After the bottom of the plate 1 is coated with the uniform adhesive, the first hydraulic rod 13 and the magnetic seat 14 are controlled to work, the magnetic seat 14 is attached to the top end of the plate 1, and therefore the plate 1 is adsorbed through the matching of the magnetic seat 14 and the wire netting. The carriage 6 is then pushed to move on the slide rail 10 by the rollers 11, thereby placing the sheet 1 over the underlying sheet 1 placed on the placement frame 3. When the plate 1 moves to a proper position above the placing frame 3, the hydraulic cylinder 17 is controlled to work, and the T-shaped frames 19 are moved away from each other, so that the support of the plate 1 is released. At this time, the first hydraulic rod 13 is controlled to work, the plate 1 is pushed to move downwards to be attached to the plate 1 at the bottom layer, then the magnetic seat 14 and the second hydraulic rod 18 are controlled to stop working, and the limit of the plate 1 at the middle layer is released. Then, the positions are returned, and at this time, the adhesive on the top of the middle plate 1 can be smeared. And then placing the plate 1 at the top above the plate 1 in the middle layer to realize the lamination of the multi-layer plates.
After the sheet 1 is completely fitted, the sheet 1 is pushed so that the sheet 1 is moved to the limit groove 28 on the press-fit plate 7 by the roller 20. The second bi-directional motor 84 is controlled to operate, and the screw 83 is driven to rotate, so that the heating ring 81 is horizontally moved in the pressing frame 4, and in the process, the heating coil completely wraps the bracket 21. Simultaneously, the electromagnetic coil 82 is controlled to work, the wire netting is heated, the adhesive is enabled to be active, gaps of all layers of veneers are filled, and good bonding of the plates 1 can be achieved before lamination. After heating, the second bi-directional motor 84 is controlled to reverse to return the heating coil. In this process, the guiding work is performed by the guide bar 85.
During pressing, the third hydraulic rod 27 is controlled to work, the pressing plate 24 is moved upwards, and the pressing plate 7 at the lower part is pushed up through the bracket 21. When the pressing plate 7 is lifted, it is moved on the guide bar 29 by the slide bush 30 to reduce the friction. When in pressing, the fourth hydraulic rod 31 is controlled to work, and the pressing plate 7 at the upper part is driven to move downwards, so that the pressing plate 7 at the lower part is matched with the pressing plate 7 at the lower part to realize pressing of the plate 1. During pressing, the fifth hydraulic rod 92 is controlled to work, the vibration exciter 94 is enabled to be in contact with the plate 1, and the vibration exciter 94 is controlled to work, so that air bubbles generated in the pressing process are eliminated, and the quality of a finished product is further improved. After the pressing, the components are controlled to return.
