Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0022] The raw fiber board slab paving process adopts figure 1 , figure 2 and image 3 The structure diagram of the push pedal head; the length of the push pedal head is 180 mm, the material is 45 steel, the push pedal head hanging lug is welded with the push pedal head panel, and a copper strip 5 is installed at the bottom of the push pedal head to prevent the push pedal head panel from Direct friction with the pressing plate; the slab is unloaded from the loading trolley to the pressing plate due to the high drop, and will be bent. When the strength of the slab is not enough, it is easy to break. 80% of the crack defects are generated on the loading trolley on the other hand, the belt conveyor used in the raw fiber board slab paving process is unstable, and the belt speed fluctuates within a certain range, with the largest fluctuation being 1.5m / mi...

Abstract

The invention discloses a fiberboard blank pavement technique and relates to the field of manmade boards. The fiberboard blank pavement technique includes the following steps that firstly, pavement hot pressing is conducted, wood fibers obtained after glue application and drying are conducted are pressed into a continuous board blank with the thickness ranging from 80 mm to 180 mm in a pavement box in advance; secondly, the board blank is conveyed to go through a next process through a belt to be cut and sawn into single board blanks, and a gradually speed reducing mode that the speed reducing amount is increased to 2 m / min from 0.5 m / min is adopted in the speed of the belt; thirdly, the single board blanks are loaded into a loading machine which pushes a rough board pressed in a pressing machine into an unloading machine through a board pushing head of a trolley, the board pushing head comprises a left hanging lug, a right hanging lug and a board pushing head panel, the two sides of the board pushing head panel are connected with the left hanging lug and the right hanging lug, the board pushing head panel is made of a bakelite plate, and the length of the board pushing head panel is increased to 250 mm from 180 mm. The fiberboard blank pavement technique can solve the problems that after pavement of the fiberboard blank is finished, the board blank is broken at the board pushing head, and cracks occur on the board surface after sanding.

Description

technical field [0001] The invention relates to the technical field of wood-based panel manufacturing, in particular to a process method for laying medium-fiber board slabs. Background technique [0002] In the manufacturing process of MDF, the slab pavement is to lay the sizing and drying wood fibers in the paving box, lay the sizing and drying wood fibers in the paving box, and pass through the leveling roller Sweeping, electronic weighing, pre-pressing, and paving into a continuous slab of a certain thickness; the slab is transported to the next process through a synchronous conveyor belt for cutting and sawing into a single slab that meets the specifications; then the single slab The slab is loaded into the loading machine with a pre-loading machine, and the loading machine pushes the slab into and unloads it on the pressing plate of the press through the trolley, and at the same time, the pushing plate head of the trolley pushes the rough board pressed in the press into...
