Description

Mixing tube assembly and glue gun with same

Technical Field

The utility model relates to a glue rifle technical field, especially relate to a mix pipe assembly and have gluey rifle of this mix pipe assembly.

Background

In machining or finishing, glue guns are often used to help users control the output of the desired material. For example, a liquid material such as silica gel, filling liquid or other substances to be applied is mounted in the glue gun, the material filling liquid in the glue gun is squeezed out by pressing the handle, and the mechanical processing of the glue gun is completed through the above-mentioned operation process.

The liquid material is usually mixed by two liquids, namely two components, which means that the filling liquid used finally is mixed by an operator and then can be used, so that the prepared filling liquid is not directly produced, because the filling liquid must be used within a short time (namely within a few hours) after being prepared, otherwise the filling liquid is invalid.

For example: the two-component coating is composed of a coating and a curing agent, the curing agent can accelerate the film forming speed of the coating, and the two-component coating is applied to a plurality of fields needing to be put into use quickly, because the actual drying time of the paint used in the industry needs one hour or even several days without adding the curing agent, the next working procedure is seriously influenced. There are also coatings that will require temporary formulation, such as two colors, or coatings plus fillers, or coatings plus catalysts.

Therefore, a mixing tube structure is needed on the glue gun to mix the two substances, the structure comprises a tube A and a tube B which are respectively filled with the two substances, one end of the pipe A and one end of the pipe B are connected with a mixing pipe to mix the materials in the pipe A and the pipe B together, so that the next operation can be carried out, however, with this arrangement, in operation, the lance tip portion end of the mixing tube needs to be positioned straight down, that is, under the action of gravity, the substances in the pipes A and B and the substances in the mixing pipes can only flow in one direction, if the glue gun is not used or used properly, such as when the gun head of the glue gun is inclined upwards or lifted, the mixed material in the mixing pipe flows backwards, that is, the material in the mixing tube flows back to the tube A or the tube B, so that the materials in the tube A and the tube B are affected, and if the materials cannot be used up at one time, the materials in the tube A and the tube B cannot be used.
