Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying equipment, in particular to a glue spraying head structure based on a glue spraying machine. Background Art

[0002] A glue spraying machine is a device that sprays glue onto materials such as panels. It is used for two-component AB glue (including polyurethane, PU glue, epoxy resin, silicone, etc.). The glue spraying head of the glue spraying machine is the mechanism for spraying the glue in the glue spraying machine. For example, some building insulation panels require the insulation layer to be fitted on the back of the panel. In this case, the glue spraying machine is used to spray glue on the back of the panel, and then the insulation layer is adhered to the back of the panel. Since there are several glue outlet holes in the glue spraying head, and the aperture of the glue outlet holes is small, when the glue spraying machine is not in use, the colloid in the glue outlet holes is easy to solidify, causing the glue outlet holes to be clogged. Once clogged, the glue spraying head needs to be disassembled for cleaning, which is very inconvenient to clean and will also cause the glue spraying equipment to be in a waiting state.

[0013] Preferably, the connecting surface of the base body is provided with a plurality of pin holes and positioning pins adapted to the pin holes; both ends of the base body are provided with end covers, and the end covers are connected to the base body by a second bolt, and one of the end covers is provided with a glue inlet joint for connecting to an external glue inlet pipe.

[0014] Preferably, lugs are provided on both sides of the end cap, and fastening bolts are provided on the lugs, and the inner ends of the fastening bolts abut against the outer side surfaces of the base body. The outer side surfaces of the two base bodies are tightened by the fastening bolts to ensure stable contact and fit of the sides.

[0015] Preferably, a connecting seat is provided at the center of the upper end of the glue spraying seat, and a connecting flange is provided at the upper end of the connecting seat, which is convenient for installation on the glue spraying machine.
