Description

Shoe upper glue machine for foot protection type sports shoes and glue coating process Technical Field The application relates to the field of shoemaking equipment, in particular to a vamp gluing machine for foot protection type sports shoes and a gluing process. Background Shoe upper gluers are a device that is specially used in the shoe industry for applying glue or adhesive to the surface of a shoe. There is a vamp glue spraying device in the prior art, including conveyer and the manipulator that is located conveyer one side, manipulator one end is fixed with and is used for spraying the gluey rifle of rubber coating material to the vamp, when gluing the vamp, starts the manipulator, when making the manipulator drive the spray gun and need the position of rubber coating towards the vamp, thereby start the spray gun later and carry out the rubber coating to the vamp. For the related art, the glue outlet end of the nozzle of the glue gun can be remained with glue coating material, and the risk of blocking the nozzle exists after the glue coating material is hardened. Disclosure of Invention In order to reduce the risk of nozzle blockage, the application provides a vamp gluing machine and a gluing process for foot protection sports shoes. The application provides a vamp glue machine for foot protection type sports shoes, which adopts the following technical scheme: A footwear athletic shoe upper glue machine, comprising: a transport rack for transporting the shoe uppers; The spray gun comprises a spray gun barrel, wherein a spray head for spraying glue to a vamp is connected in a sliding manner in the spray gun barrel, an air inlet pipe communicated with the interior of the spray gun barrel is connected to the outer wall of the spray gun barrel so as to push the spray head to move through air pressure provided by the air inlet pipe, and an air pump is arranged at one end of the air inlet pipe, which is away from the spray gun barrel; the sealing piece is positioned at one end of the spray head, which is away from the air inlet pipe, an elastic piece is arranged between the sealing piece and the spray head, the elastic piece has elastic potential energy for pushing the spray head to the air inlet pipe, and when the air pump is closed, the spray head can be far away from the sealing piece under the action of the elastic piece; and the manipulator is positioned on one side of the transportation frame, and one end of the manipulator is connected with the spray gun pipe. Through adopting the technical scheme, when the vamp is glued, the vamp is fixed above the transportation frame, the manipulator is started, the manipulator drives the spray gun pipe to move, when the spray head faces the part of the vamp, which needs gluing, the manipulator stops acting, then the air pump is opened, the air pump conveys air to the inside of the spray gun pipe through the air inlet pipe, then the spray head approaches the rubber plug under the action of air pressure until the glue outlet end of the spray head stretches out of the rubber plug through the sealing hole, then the spray head is started, glue is sprayed to the vamp, after the vamp gluing is finished, the air pump is closed, the spray head moves away from the rubber plug under the action of the elastic piece until the glue outlet end of the spray head is retracted into the rubber plug through the sealing hole, and the inner wall of the sealing hole wraps the glue outlet end of the spray head due to certain elasticity, so that the residual glue at the glue outlet end of the spray head is hardened by contact with air, and the risk of the spray head blocking is caused. Optionally, the shower nozzle includes the shower nozzle body, the inside chamber of gluing that has seted up of shower nozzle body, shower nozzle body outside is equipped with into rubber tube and advances rubber tube and glues the chamber intercommunication, the one end that advances the rubber tube and deviate from the shower nozzle body is connected with gluey pump, the one end that the shower nozzle body deviates from the intake pipe is equipped with the needle, the needle passes through sealed hole and rubber buffer sliding connection. Through adopting above-mentioned technical scheme, after starting the air pump, gas is carried to the spray gun intraductal through the intake pipe, and the shower nozzle is close the rubber buffer gradually under the atmospheric pressure effect afterwards until the needle passes the sealed hole, and then the gluey pump starts, sprays the rubber coating material on the vamp. Optionally, the inside needle that is equipped with of spray gun pipe, the through-hole has been seted up to the one end that the shower nozzle body deviates from the needle, the needle passes through-hole and shower nozzle body sliding connection, needle outer wall and needle inner wall butt.
