Shoe machine with automatic glue adjustment device

This creation department is related to the shoe making machine. In more detail, it refers to a shoe making machine with an automatic glue amount adjusting device, which can automatically adjust the glue feeding speed of the rubber strip according to the feeding speed of the rubber nozzle.

The shoe-making machine of the prior art, such as the front machine or the rear machine, is mainly used to automatically attach the sole to the upper, which is mainly driven by a hydraulic cylinder to move the left and right rubber nozzles to produce axial movement, and The two rubbing nozzles can simultaneously or individually create a kneading action so that the rubbing nozzles can move along the front, middle or back edge of the sole. Furthermore, the rubber nozzles are externally connected to a glue feeding mechanism, and the glue feeding mechanism can transport a hot melt adhesive strip into the rubber nozzle, and after the rubber nozzle is heated and melted, the glue nozzle is coated with the action of the rubber nozzle. It is placed on the edge of the sole to facilitate the subsequent inspection of the upper.

However, the weather temperature will affect the viscosity of the hydraulic oil, which will cause the speed of the hydraulic cylinder to change, or as the size of the shoe changes, so the shoe making machine is mostly designed to allow the user to adjust the speed of the hydraulic cylinder. However, if the operating speed of the hydraulic cylinder is changed, if the feeding speed of the rubber feeding mechanism is not adjusted correspondingly, when the hydraulic cylinder operating speed is adjusted faster, the thickness of the rubber coating is insufficient, and the adhesive strength of the upper is insufficient, and if the hydraulic cylinder is in motion, When the speed is slowed down, it will cause the glue to be too thick and the rubber to overflow. Therefore, after the hydraulic cylinder speed is adjusted, the user has to adjust the glue feeding speed of the glue feeding mechanism. If the user's technology is not skillful, it is necessary to repeat the adjustment several times to make the thickness of the glue meet the demand. Therefore, it is necessary to automatically adjust the amount of glue and the speed of the glue to automatically respond to the displacement speed of the glue device.

In order to solve the defects and inconveniences caused by the above-mentioned conventional technology, the present invention proposes a shoemaking machine with an automatic glue amount adjusting device, which has an automatic glue amount adjusting device, which can automatically follow the feeding speed of the rubber nozzle.
