Embodiment 1

[0017] Such as figure 1 The shown sweeping roller device of the paving machine includes a paving mesh belt 1 provided with a feed end 1-1 and a discharge end 1-2, and a sweeping roller 6 is arranged above the paving mesh belt 1, and the sweeping roller 6 passes through the bearing The seat is installed on the frame 2. In this embodiment, a leveling roller 4 is provided on the frame 2 near the feed end side of the paving mesh belt 1 of the leveling roller 6, and the leveling roller 4 is placed on the frame above the leveling roller 4. There is a guide plate 2-1 obliquely, and the lower end of the guide plate 2-1 is close to the feed end 1-1 of the pavement mesh belt 1; The bearing carriage 3 is provided with two vertical guide rods 5 on both sides respectively, the vertical guide rods 5 are installed in the sliding sleeve 3-1, and the two sliding sleeves 3-1 are welded on both sides of the linear bearing carriage; The linear bearing carriage 3 is slidingly connected with the c...

Embodiment 2

[0019] The bending angle a between the opposite plow blades is 130 degrees, and other features are the same as in Embodiment 1.

Embodiment 3

[0021] The bending angle a between the opposite plow blades is 140°, and other features are the same as in Embodiment 1.

[0022] When working, since there is a leveling roller at the feeding front end of the leveling roller, the fiber blank that falls to the feeding end of the pavement mesh belt through the guide plate first passes through the leveling roller, and the leveling roller can smoothly and quickly move the excess coarse fibers to a uniform direction. The flattened fiber slab passes through the sweeping roller again, and the transverse density distribution and thickness of the produced MDF are more stable, and the flatness of the MDF during the paving process does not exceed Poor, the lateral density deviation and thickness deviation of the quality of the finished MDF board are small; the average density deviation of the MDF produced by statistics is -0.83 and +0.78, and the maximum deviation is 1.13, which achieves higher accuracy; while increasing dial The average...

Abstract

The invention discloses a felting machine levelling roller device, and relates to the technical field of felting machine manufacturing. The felting machine levelling roller device includes a felting mesh belt provided with a feeding end and a discharging end, a levelling roller is arranged above the felting mesh belt, and the levelling roller is installed on a machine frame; at least one spreadingroller is arranged, near the feeding end, at one the side of the leveling roller on the machine frame, and both ends of the spreading roller is installed on a linear bearing carriage, and the linearbearing carriage is provided with vertical guide rods and is slidably connected with sliding grooves formed in the machine frame through the vertical guide rods; and a screw for controlling lifting ofthe linear bearing carriage is arranged on the machine frame. Compared with the prior art, the felting machine levelling roller device can solve the problem that density deviation and thickness deviation of production boards of existing medium density fiberboards are large.

Description

technical field [0001] The invention relates to the technical field of paving machine manufacturing, in particular to a leveling roller device for an air paving machine. Background technique [0002] Air paving machine is one of the main equipment of MDF production line. The paving machine includes a paving mesh belt provided with a feed end and a discharge end, a sweeping roller above the paving mesh belt, the sweeping roller is mounted on a frame, and the frame is placed on the sweeping roller. A guide plate is obliquely placed on the feed end side of the roller, and the lower end of the guide plate is close to the feed end of the paving mesh belt. This kind of air-flow paving machine has the following problems in the production process: the fiber falls on the paving mesh belt through the guide plate to form a blank and directly passes through the sweeping roller. Therefore, the fiber laying before the sweeping roller is prone to unevenness, resulting During the paving p...
