Abstract

The invention discloses a control device and control method for automatically mixing glue. The control device comprises a weighing sensor (9), a signal processing circuit, a strong and weak current coupling circuit and a strong current control circuit, wherein the weighing sensor (9) is arranged at the bottom part of a glue mixing container (1); the signal processing circuit is mutually connected with the output end of the weighing sensor (9); the strong and weak current coupling circuit is mutually connected with the output end of the signal processing circuit; the strong current control circuit is mutually connected with stock tanks (3, 4 and 5) and feed pumps (6,7 and 8); the output end of the strong and weak current coupling circuit is mutually connected with the input end of the strong current control circuit; the signal processing circuit comprises a temperature compensation circuit and a two-stage differential amplifying circuit; and the strong and weak current coupling circuit is provided with a bidirectional thyristor. A weight quantitative glue mixing method is adopted by the control method. The control device disclosed by the invention is simple in structure, easy in processing and manufacturing, low in cost and high in working accuracy and efficiency. The control method is simple and easy in implementation and convenient in maintenance.

Description

technical field

[0001] The invention relates to an electric control device used in a glue blending program in wood processing production, in particular to a control device and a control method for automatic glue blending. Background technique

[0002] With the increasing scarcity of forest resources in our country, there are fewer and fewer large-diameter timbers. In order to meet the needs of industrial and agricultural construction and people's lives, the timber industry can only use small-diameter timber in large quantities, or glue them together with adhesives, or manufacture wood-based panels. This makes the amount of glue used in the wood industry more and more. Glue mixing is an extremely important process in wood processing and production. It is to mix raw glue, water, additives, etc. in a certain proportion and stir evenly to prepare a glue solution that meets the process requirements. The quality of the prepared glue will directly affect the quality of wood produ...
