Description

Technical Field

[0001] The utility model relates to the field of lasting machines, in particular to a shoe upper preheating and drying structure of a lasting machine. Background Art

[0002] The upper of injection molded shoes is generally first formed on the upper mold, and then the upper mold and the upper are put into the injection molding machine together to injection mold the sole so that the sole and the upper are firmly bonded together. Since a lot of labor is reduced in the production process, the price is affordable, and since no glue is used in the sole molding process, the harm of glue to the human body can be avoided.

[0003] In order to achieve semi-automatic or even automated production, multiple sets of sole mold clamping mechanisms and shoe lasts can be set on a rotating platform, and each clamping mechanism and shoe last are evenly distributed around the rotating platform. However, before putting the upper on the shoe last, it is necessary to ensure that the surface of the upper is dry to ensure that the upper and the sole are firmly bonded during the injection molding process. However, currently, after the upper is made, it needs to be dried in other special equipment and then transported to the upper-drawing machine for upper-drawing operation, which is cumbersome to operate and has low production efficiency. Utility Model Content

[0004] The utility model aims to provide a shoe upper preheating and drying structure of an upper drawing machine, which can dry the surface of the shoe upper before shoe upper drawing, reduce the number of times of transporting the shoe upper, and improve production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a shoe upper preheating and drying structure of an upper lasting machine, comprising a shoe placement bin arranged above a rotating platform of the upper lasting machine, an opening being arranged on an outward side of the shoe placement bin; an exhaust port and a blow port being arranged on a wall of the shoe placement bin, an exhaust fan and an air duct being arranged on the outside of the shoe placement bin, a heating device being arranged in the air duct; the exhaust port, the exhaust fan, the air duct and the blow port being sequentially connected along the air flow direction.

[0006] As a further improvement of the utility model, the exhaust port and the blowing port are both arranged on the top surface of the shoe placement bin; the exhaust port is located close to the opening of the shoe placement bin, and the blowing port is located far away from the opening of the shoe placement bin.

[0007] As a further improvement of the utility model, the heating device includes a bracket with at least three reinforcing ribs, each reinforcing rib is arranged around the center line of the bracket, a heating wire is wound around the bracket, and the bracket and the heating wire are both located in the air duct.

[0008] As a further improvement of the utility model, a plurality of grooves are provided on the outer edge of the reinforcing rib of the bracket, and the heating wires are embedded in the grooves of the reinforcing rib.

[0009] As a further improvement of the present invention, a first connecting plate is provided at one end of the bracket, a vent is provided in the middle of the first connecting plate, and one end of the bracket is connected to the edge of the vent; a second connecting plate is provided at the exhaust port of the exhaust fan, and the first connecting plate is connected to the second connecting plate.

[0010] As a further improvement of the present invention, the shoe storage bin is connected to a protective panel, and the exhaust fan and the air duct are both located on the back side of the protective panel.

[0011] Beneficial Effects

[0012] Compared with the prior art, the advantages of the upper preheating and drying structure of the upper lasting machine of the utility model are:

[0013] 1. When the person standing next to the upper drawing machine puts the upper on the shoe last and performs the sole mold injection molding, the upper to be processed can be placed in the shoe storage bin first, and a circulating airflow is formed in the shoe storage bin through the exhaust fan and the air duct, and the circulating airflow is heated by the heating device to dry the upper. This method does not require the upper to be transported to a separate workstation for drying, which reduces the number of transportations and improves work efficiency.

[0014] 2. The position of the exhaust vent is close to the opening of the shoe storage compartment, and the position of the air blowing vent is far away from the opening of the shoe storage compartment. This is conducive to allowing the exhaust vent to draw dry air from outside the shoe storage compartment when exhausting air, so as to quickly discharge the moisture in the shoe storage compartment and improve the drying efficiency.

[0015] 3. In the heating device, a heating wire is wound around the bracket, and the groove of the bracket reinforcement rib plays a positioning role for the heating wire. The bracket ensures the rigidity of the heating device, avoids the shaking of the heating wire due to the frequent rotation and braking of the rotating platform of the lasting machine, and extends the service life of the heating device.
