The utility model content

In view of this, the purpose of this utility model provides a kind of pair of component coating gun, be provided with separate material feed path and bi-component can be mixed the static mixer that sprays, it is independent fully before that different component materials enter static mixer, keep not contacting mutually, shortened the passage length that flows through after different components mix, the material flow resistance is little, coating gun is cleared up easily, need not the solvent washing system, the coating gun maintenance time is short, cost is low, and attended operation is simple, can obtain the longest gluing time, be beneficial to and enhance productivity.

Of the present utility model pair of component coating gun comprises being used for the shunting rifle head that component A and B component are distributed and being fixed in the static mixer that is used for component A and B component are mixed spraying of described shunting rifle head outlet of the fluid supply apparatus that is provided with component A independence feed path and B component independence feed path, the component A independence feed path that is fixed in described fluid supply apparatus and B component independence feed path outlet.

Further, described shunting rifle head is provided with the sprue that is communicated in component A independence feed path and is communicated in B component independence feed path and the flow road isolated with described sprue; Described flow road comprises that the outlet of at least two runners and each runner is uniform around the sprue outlet;

Further, described flow road comprises two runners, and the outlet of two runners is respectively in sprue outlet both sides and equal with the sprue outlet;

Further, described component A independence feed path and B component independence feed path are respectively equipped with the control valve assembly that is used to carry out break-make and flow-control;

Further, described control valve assembly comprises valve seat, spool and control cylinder; Described valve seat constitutes the part of component A independence feed path or B component independence feed path; Described spool by the holddown spring plug in valve seat; Described control cylinder is for promoting the single-acting cylinder of spool compression holddown spring.

The beneficial effects of the utility model are: of the present utility model pair of component coating gun, be provided with separate material feed path and bi-component can be mixed the static mixer that sprays, it is independent fully before that different component materials enter static mixer, keep not contacting mutually, shortened the passage length that flows through after different components mix, the material flow resistance is little, coating gun is cleared up easily, need not the solvent washing system, the coating gun maintenance time is short, cost is low, and attended operation is simple, can obtain the longest gluing time, is beneficial to and enhances productivity.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:
