RU47801U1 - DEVICE FOR LAMINATION OF PLATES - Google Patents

Abstract

The technical solution relates to woodworking, namely: devices for hot cladding of building, furniture, etc. plates (fiberboard, DVL, GVL, etc.) paper, film, plastic, veneer. The technical result of the claimed technical solution is to ensure high-quality bonding of the facing material over the entire area of the slab having deviations of the thickness size over the entire area. The technical result is achieved by the fact that in the device for laminating plates including a table for blanks, a press containing lower and upper horizontal rigid plates with a drive for moving, a device for heating the upper plate, the mechanism for removing the finished product from the press, the lower press plate is additionally equipped with a membrane rigidly fixed to it with the formation of a pneumatic chamber communicating with the compressor, and the upper plate is lined with sheet aluminum.

Description

The technical solution relates to woodworking, namely: devices for hot cladding of building, furniture, etc. plates (fiberboard, DVL, GVL, etc.) paper, film, plastic, veneer.

Known hydraulic presses model GP-60; GP-80 for covering with paper, plastic, veneer, full-format plates or pre-cut blanks, including plates for placing blanks between them, a plate heating system, plate movement mechanism for compressing blanks (see the copy from the information source on a separate sheet).

A device is known for double-sided cladding of furniture panels, including a table for blanks, a hydraulic press PSGE-1M, containing lower and upper horizontal plates with hydraulic drive for moving the lower plate for crimping blanks, a mechanism for heating the plates, a mechanism for removing the finished product from the press (see copy from the source of information on a separate sheet).

A disadvantage of the known devices is the low quality of the coating for plates having some deviations of the thickness size in area, due to the implementation of plates for crimping workpieces from hard material.

The technical result of the claimed technical solution is to ensure high-quality bonding of the facing material over the entire area of the plate having deviations of the thickness size over its area.

The technical result is achieved by the fact that in a device for laminating plates including a table for blanks, a press containing lower and upper horizontal rigid plates with a drive for moving, a device for heating the upper plate, a mechanism for removing the finished product from the press, the lower press plate is additionally equipped

a membrane rigidly fixed to it with the formation of a pneumatic chamber communicating with the compressor, and the upper plate is lined with sheet aluminum.

The supply of the lower press plate with a membrane rigidly fixed on it, with the formation of a pneumatic chamber communicating with the compressor, provides high-quality lamination of building and furniture plates, including those having a deviation in the size of the plate thickness over its area, because the support for the workpiece in the form of an elastic chamber tightly touches every point on the surface of the workpiece and therefore creates a uniform force of pressing it to the top plate, and, therefore, uniform heating of it from the aluminum sheet of the top plate.

The device for laminating plates includes a table 1 for blanks, a press containing the upper plate 2, lined with aluminum sheet 3 and provided with a heating mechanism, the lower plate 4, which acts as a support and placed on the frame 5. A membrane 6 is fixed with a gap on the lower plate 4, made, for example, of rubber grade TMKSH, forming a pneumatic chamber 7, communicating with the compressor. The press simultaneously comprises a drive for moving the upper plate 2 and a mechanism for removing finished products from the press, made, for example, in the form of a conveyor belt 8.

A device for laminating plates works as follows.

The plate intended for cladding is laid on table 1, the adhesive composition is applied to the surface of the plate and cladding material (paper, film, plastic or veneer) is applied to it. Then, the plate is transferred to the conveyor belt 8 and fed into the loading gap between the aluminum sheet 3 of the upper heated plate 2 and the membrane 6 of the pneumatic chamber 7 of the lower plate 4, while moving the upper plate 2 sets the loading clearance 10 mm larger than the thickness of the workpiece. Next, open the valve of the pneumatic system and the air from the compressor is fed into the pneumatic chamber 7, while the workpiece is pressed to the aluminum sheet 3 of the upper plate heated to the required temperature (100-180 ° C). The required temperature is maintained using the sensor

regulator, and the required specific pressure - by setting the electrical contact pressure gauge. The pressure is maintained for a predetermined time, then released, and the finished product with a lined surface is moved by conveyor 8, removing from the press.

An easy-to-manufacture laminating device that provides high-quality coverage in one cycle of full-format plates, as well as pre-cut blanks made of fiberboard, DVL, GVL, paper, film, plastic, veneer, will find industrial application.
