Automatic hot melt adhesive bar glue outlet machine

Abstract

The invention discloses an automatic hot melt adhesive bar glue outlet machine. The automatic hot melt adhesive bar glue outlet machine comprises a glue inlet mechanism, a glue melting mechanism and aglue outlet mechanism; the glue inlet mechanism comprises a gear with rotating power, the axis of the gear is in the horizontal direction, teeth of the gear make contact with a vertical rubber bar, the rubber bar is in a solid bar shape, the glue melting mechanism comprises a heating pipe arranged below the glue inlet mechanism, the top of the heating pipe is provided with an upper opening matched with the rubber bar in a seal manner, the heating pipe melts the rubber bar inserted into the heating pipe into the liquid state, the glue outlet mechanism comprises a glue outlet pipe on the bottomof the glue melting mechanism, the bottom of the glue outlet pipe is provided with a narrowing segment with the inner diameter gradually reduced in the downward direction, a ball body is arranged inthe narrowing segment, the inner diameter of the glue outlet pipe is larger than the diameter of the ball body, the inner diameter of the bottom of the narrowing segment is smaller than the diameter of the ball body, and the ball body is connected with the top of the glue outlet pipe through a pressure spring. Pressure changes brought by glue bar inlet and outlet achieve glue outlet control, the whole equipment is low in cost, simplicity and reliability are achieved, solid glue feeding is facilitated, and outflow of fluid-shaped rubber liquid is ensured.

Description

technical field [0001] The invention relates to the field of gluing equipment, in particular to an automatic hot-melt glue stick gluing machine. Background technique [0002] Some small-sized plastic parts are fixed with glue, but the dispensing mechanism often needs to be equipped with pneumatic equipment to realize the glue, and a precise shut-off valve is needed to control the glue or not. Sometimes, as the room temperature changes Changes, the glue may solidify, and it is necessary to prevent the unextruded glue from solidifying, so that it does not have fluidity, and even some glues used as raw materials are solid at room temperature, and must be turned into fluids to achieve subsequent dispensing , so often the entire glue machine often has high equipment costs and is difficult to control. Contents of the invention [0003] The problem to be solved by the present invention is to provide an automatic hot-melt glue stick dispensing machine, which uses the pressure cha...
