Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of production of silicon steel, in particular to a moving structure of a silicon steel recoiling glue spraying machine. BACKGROUND

[0002] The glue spraying machine is a new automatic equipment in modern industry, which can spray glue on products with different sizes and shapes. The performance of the glue spraying machine mainly includes the following requirements: adjustable spraying shape, adjustable glue amount, adjustable glue supply and suction amount, spraying glue with different viscosity, easy cleaning of the glue spraying chamber, etc. Silicon steel is a magnetic material, which is mainly used in motors, transformers, electrical appliances and electrical instruments, and has the characteristics of high permeability, low coercive force, large resistance coefficient, etc., so the magnetic hysteresis loss and eddy current loss are small. The purpose of spraying glue on the surface of silicon steel is to limit the eddy current loop, so that the eddy current can only flow in one piece. The impedance of the eddy current loop is large, which limits the value of the eddy current. If the silicon steel pieces are not insulated, the eddy current will pass through the adjacent silicon steel pieces. The impedance of the eddy current loop is smaller than that of a single piece, so the eddy current will increase, which will rapidly increase the loss generated by the eddy current.

[0003] Generally, the moving of the recoiling glue spraying machine in the cold-rolled silicon steel workshop of the general cold-rolling mill adopts a constant-speed motor screw rod device. Since the movement of the glue spraying gun is driven by the rotation of the screw rod, the movement speed of the glue spraying is slow.
