[0002] Safety shoes are a general term for safety shoes and protective shoes. They generally refer to shoes worn in different working situations that protect the feet, legs and human body from foreseeable injuries. During the production and processing of safety shoes, one of the steps is to apply adhesive between the upper and the sole to connect them, and then put them in an oven for baking and drying to make the adhesive bond quickly. For example, Chinese invention patent publication number CN108338442A discloses a processing technology for safety shoes, which records the above processing steps.

[0003] Although the above patent discloses the specific processing steps of safety shoes, it does not disclose the specific processing equipment.

In addition, during the processing, the upper needs to be manually put on the outside of the shoe last to keep it fixed, so the shoe last also needs to enter the oven together with the bonded safety shoes for baking. The baked safety shoes and the shoe last have a high temperature, which is not convenient for manual separation. Therefore, based on the defects of the prior art, the present invention provides a production and processing equipment for safety shoes to solve the above problems. Summary of the invention

[0016] The beneficial effects of the present invention are:

[0017] 1. When in use, the upper of the shoe after applying the adhesive can be put on the outside of the shoe last, and then the shoe last bracket can be moved downward to drive the shoe last and the safety shoe to move toward the sole supporting plate, so that the sole supporting plate abuts against the sole, and the relative force between the shoe last and the sole supporting plate can be used to clamp and fix the shoe upper and the sole, thereby avoiding the situation of debonding during the movement of the safety shoe. A work station can be set on the front side of the base, and the operator can manually put the upper of the safety shoe on the outside of the shoe last, and the conveyor belt wheel assembly can rotate slowly, so that the operator has sufficient time to operate, and the conveyor belt wheel assembly drives the safety shoe into the drying box for baking, and after coming out of the other end of the drying box, the heel push plate and the toe push plate inside the shoe last work successively, and the safety shoe with a high temperature after drying can be pushed off the shoe last, and the safety shoe is no longer removed manually.

[0018] 2. A drying tube is connected to the top of the shoe last, and the drying tube is connected to a hot air supply device, which can provide hot air to the drying tube. A plurality of drying holes are provided at the bottom of the shoe last along its length direction, and a hot air channel is provided inside the shoe last, through which the plurality of drying holes can be connected to the drying tube, and each of the drying holes is provided with a drying groove on both sides of the shoe last. After the drying tube supplies air to the plurality of drying holes, the hot air can be ejected from the drying holes and extend along the drying groove to the left and right sides of the shoe last, so that the hot air can diffuse inside the safety shoes, thereby heating and baking the inside of the safety shoes, and cooperating with the drying box to bake the outside of the safety shoes, the bonding speed and efficiency can be further accelerated.

[0019] 3. When in use, the shoe last needs to be the same size as the safety shoe in order to prop up the shoe upper. In order to quickly put the shoe upper on the outside of the shoe last, the shoe last contraction screw rod can be used to drive the shoe last head to the root of the shoe last, so that the size of the shoe last becomes smaller, which is convenient for the installation of the safety shoe. After the safety shoe is put on the outside of the shoe last, the shoe last contraction screw rod can be used to drive the shoe last head away from the root of the shoe last, so that the shoe last props up the upper of the safety shoe. The above operation can achieve the purpose of quickly putting the shoe upper on the outside of the shoe last. When the distance between the root of the shoe last and the head of the shoe last changes, the drying spiral tube is extended and retracted accordingly, and the drying spiral tube can supply air to the multiple drying holes at the bottom of the head of the shoe last.

[0020] 4. When the safety shoes are baked, the heel electric push rod can be started to extend its telescopic rod, so that the heel push plate moves downward to push the root of the safety shoe downward, so that the root of the safety shoe is separated from the root of the shoe last. At this time, the toe electric push rod can be started to extend its telescopic rod, thereby driving the toe push plate to push the safety shoe off the head of the shoe last, thereby replacing the manual operation of automatically removing the safety shoes.

[0021] 5. Since the edge of the sole is higher than the bottom of the upper, in order to avoid the phenomenon of debonding between the edge of the sole and the upper, the surrounding side of the safety shoe needs to be clamped and fixed. Through the above structure, after the sole support plate abuts against the sole, the four shoe surrounding extrusion rods can be moved toward the inside of the shoe surrounding extrusion groove at the same time, thereby driving the four shoe surrounding extrusion plates to move toward the surrounding side of the safety shoe at the same time, so that the four shoe surrounding extrusion air cushions abut against the side of the safety shoe, thereby flexibly extruding, clamping and fixing the surrounding side of the safety shoe.
