Method for automatically adjusting wood shaving filling quantity of glue blender

Abstract

The invention discloses a method for automatically adjusting wood shaving filling quantity of a glue blender. The glue blender comprises a blocking mechanism which is arranged at a discharge port position of a shell body and is used for changing opening degrees of the discharge port. The method comprises the following steps. Firstly, wood shavings enter the shell body from a feed port and are pushed from a feed area to a blending area in sequence to be glued, and the motions of the blocking mechanism are controlled to enable the opening degree of the discharge port to be at a preset position. Secondly, wood shaving filling quantity in the blending area is detected, and an operator judges whether the wood shaving filling quantity reaches the preset filling quantity. If the wood shaving filling quantity in the blending area does not reach the preset filling quantity, the blocking mechanism is controlled to adjust the discharge post to be in an opening degree corresponding to the detected wood shaving filling quantity. The steps are repeatedly carried out until the wood shaving filling quantity in the blending area reaches the preset filling quantity, and the blocking mechanism is controlled to adjust the opening degree of the discharge port to be at the preset position. According to the method, operation states of the glue blender are detected in real time to control the blocking mechanism to change the opening degrees of the discharge port in real time so as to adjust the wood shaving filling quantity in the shell body, and therefore glue liquid is enabled to be evenly distributed, production cost is effectively saved, and the quality of produced shaving boards is improved.

Description

technical field [0001] The invention relates to the technical field of wood-based panel manufacturing, in particular to a method for automatically adjusting the filling amount of shavings in a glue mixing machine. Background technique [0002] At present, the glue mixers widely used in the particleboard production line are basically ring glue mixers. The characteristic of the ring-type glue mixer is: after the shavings enter the glue mixer, they are driven by the high-speed rotating stirring shaft of the glue mixer to form a spiral loop along the inner wall of the glue mixer. According to the distribution of different glue mixing heads on the stirring shaft, the glue mixer is divided into four areas along the axial direction, the feeding area, the glue applying area, the mixing area and the discharging area (feeding area). After the shavings enter the glue mixing machine, they move forward under the push of the glue mixing head in the feeding area; they enter the sizing are...

AI Technical Summary

Problems solved by technology

When the amount of shavings is too small, although the amount of shavings is also reduced, the amount of sizing is still too large for some shavings, which wastes the glue, so the shavings inside the glue mixer need to reach a certain amount of filling.

However, the glue mixing machine in the prior art cannot always ensure that the filling amount of the shavings is effectively controlled within a reasonable range of the glue amount, thus wasting a large amount of glue and increasing the production cost
