Embodiment Construction

[0021] Provide specific embodiments below in conjunction with accompanying drawings.

[0022] Embodiments of the present invention are specifically as figure 1 shown. After the paved detection slab 10 is sent to the detection position, the blower 1 of the blowing part sends the air to the blowing cavity 3 through the pipe 2, and the pressing roller 4 made of rubber prevents the air from leaking out; blows the air into the recombined material Slab; use the detection sensor 9 of the detection part and the detection control instrument 8 to detect the position where the air velocity is too high, and the pavement density of the slab at this position is low; Spray marks, after the inspection is completed, fill the mark with appropriate raw materials to make up evenly to form a hot-pressed slab.

[0023] Other embodiments of the invention.

[0024] For different raw material forms, changing the distance between the detection sensor and the marking nozzle, such as 5 cm, 8 cm, to me...

Abstract

The invention discloses a method and a device for detecting the forming evenness of a recombinant material slab. The device consists of an air blowing part, a detection part and a marking part. Compressed air is blast into the recombinant material slab which is transferred forward, a wind speed sensor is used to detect the wind speed difference at different positions, and a marker is spray-coatedat the position where the wind speed has obvious change. The device for detecting the recombinant material slab can be used with a recombinant material slab forming machine and slab processing equipment by matching. The method and the device for detecting the recombinant material slab have the advantages that: (1) the method and the device can finish the detection and marking on production lines,and have a simple process; and (2) the method and the device have a simple detection principle and reliable equipment, and can effectively solve the problem of uneven slab forming.

Description

technical field [0001] The invention relates to a detection device for an intermediate process of wood-based panel production, which belongs to the technical field of wood-based panel industry, and specifically relates to a detection method and a detection device for the uniformity of a heavy wood slab. Background technique [0002] The use of crop straw, fruit branches, branch wood, etc. to manufacture recombined wood can solve the problem of tight supply of wood-based panels. In the process of producing heavy wood such as crop straw, fruit branches, and branch wood, the uniformity of paving the slab before pressing is an important process that determines the quality of the heavy wood. [0003] Traditional wood-based panels use mechanical paving to control the thickness and uniformity of the slab. There is no suitable paving uniformity testing equipment, and the uniformity of crushed wood chips and scraps can be controlled within a certain range. For the long-length, debri...
