Description

Panel laying machine

technical field

The utility model belongs to a conveying device used in the field of plate processing, in particular to a plate paving machine for transporting raw materials.

Background technique

For board production enterprises, the slab is made by paving the paving head of the paving mechanism. For example, when producing particleboard, it is necessary to lay three layers of material and then enter the press. However, in the actual production process, the core layer paving is After the paving of the lower surface layer is completed, the material falls freely on the lower surface layer, so that after the material falls, many long shavings are not laid flat on the slab, and the free-falling shavings on the slab are not dense. When paving the upper surface layer, due to the relationship between the thickness of the surface layer material, for example, if the surface layer material is too thick, the production cost will be increased, and it will have a great impact on the static bending strength index. Some upright core layer particles cannot be fully covered, so the surface of the particleboard is prone to roughness. wood shavings. There will be air in the slab produced by the press, which will reduce the quality of the product, and there will be unevenness on the surface. Therefore, a kind of simple in structure, improves product quality, reduces the slab material paving machine of slab thickness to be proposed.

Contents of the invention

The purpose of the utility model is to provide a plate paving machine which has a simple structure, reduces production costs and improves the qualified rate of finished products.

The utility model comprises a lower surface material spreading device (1), a core layer material spreading device (2) and an upper surface material spreading device (4), and is characterized in that: a core layer material spreading device (2) and an upper surface material spreading device ( 4) A pre-compression mechanism (3) is provided between them, and the pre-compression mechanism (3) includes: a pre-compression roller (3-1) and a fixing device, and the fixing device includes a pull rod (3-2), a bracket (3 -3) and the adjusting bolt (3-4), one end of the pull rod (3-2) is connected with the pre-compression roller (3-1), the bracket (3-3) is located at the other end of the pull rod (3-2), and Fix by adjusting screw (3-4).

During actual use: the support (3-3) can be fixed on the frame, and one end of the pull rod (3-2) passes through the support (3-3), and the pre-compression roller (3-4) is adjusted by the adjusting bolt (3-4). 1) The distance from the slab, adjust the thickness of the slab after pre-pressing, the air inside can be squeezed out of the slab pre-pressed by the pre-pressing roller, and the flatness of the slab can be improved.

As an improvement, two sets of fixing devices are provided, and the two sets of fixing devices form a "V"-shaped angle.

Compared with the prior art, the utility model has the advantages of simple structure, reduced labor intensity, stable use and the like.
