Automatic spray nozzle

Abstract

The invention discloses an automatic spray nozzle. The automatic spray nozzle comprises a rack, a first air cylinder and a second air cylinder which are vertically arranged on the rack, a transverse frame which is erected between a piston rod of the first air cylinder and a piston rod of the second air cylinder, a sliding rail structure which is arranged on the transverse frame, a rhombic array retractable frame which is arranged between a sliding block of the sliding rail structure and a first end of the transverse frame, a supporting structure which is arranged on the rhombic array retractable frame, a pulse valve group which is arranged on the supporting structure, a water pump which is connected with the pulse valve group and a PLC (Programmable Logic Controller) which is electrically connected with the pulse valve group, wherein the piston rod of the first air cylinder and the piston rod of the second air cylinder synchronously ascend and descend; the rhombic array retractable frame is formed by at least two groups of X-shaped dual-rod pieces with middle parts which are hinged together; the pulse valve group comprises at least one pulse water valve; a water inlet of the pulse water valve is connected with the water pump through a water pipe; an electric mechanism of the pulse water valve is connected with the PLC.

Description

technical field [0001] The invention relates to the field of fiberboard processing, in particular to an automatic spray head. Background technique [0002] In the fiberboard production line, due to the high surface bonding strength, high surface hardness and low surface water content of the traditional board base material, the board base material is prone to dry and wet spots, cracks and other problems during direct processing; therefore, it is necessary to During processing, the surface of the sheet is sprayed with water, and the progress of the spray angle, spray uniformity, water spray volume and automatic adjustment of the water spray operation needs to be improved urgently. Contents of the invention [0003] For this reason, the present invention proposes an automatic spray head that can solve the above problems or at least partially solve the above problems. [0004] The present invention proposes an automatic spray head, comprising: a frame, a first cylinder and a ...
