Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing, and in particular to a sole pressing machine for shoe making. Background Technology

[0002] Shoes are an essential part of human life, protecting our feet from injury. Shoes come in many varieties depending on their manufacturing process. The connection between the shoe upper and the sole is mainly divided into two types: stitching and gluing. In modern industrial mass production, shoe production is mainly based on gluing.

[0003] Currently available shoe sole pressing machines on the market generally have a relatively traditional structural design, mostly equipped with only two pressing devices: one on the top and one on the side. These two devices primarily focus on the ball area and side edges of the sole, ensuring these key areas receive sufficient pressing. However, this design has a significant drawback: the pressing force and effect on the front and rear ends of the sole are often less than ideal. Since the front and rear ends experience greater bending and tensile forces during shoe wear, insufficient pressing greatly increases the risk of the sole coming apart.

[0004] Therefore, those skilled in the art have provided a sole pressing machine for shoemaking to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shoe sole pressing machine. By adding a pressing mechanism to easily delaminated areas, the pressing effect is enhanced, reducing the possibility of delamination in these areas and extending the lifespan of the shoes.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A shoe sole pressing machine includes a machine housing, a limiting shell, and a support frame. The limiting shell is fixedly installed on the top of the machine housing. Multiple hydraulic telescopic rods are fixedly installed on the left and right side walls inside the limiting shell. The ends of the hydraulic telescopic rods are fixedly connected to fixed pressing heads. Two side pressure rubber plates are installed in the middle of the limiting shell.

A bushing is provided at the bottom of the limiting groove. The bushing is rotatably connected to the bidirectional stud.

[0012] The above technical solution enables the pressing of the toe and heel areas of the shoe.

[0013] Furthermore, both ends of the limiting shell are fixed with slide rails, one end of each slide rail is fixed with a No. 1 servo motor, the power output end of each of the two No. 1 servo motors is connected to a lead screw, the two lead screws are threaded to the tail of the No. 2 electric telescopic rod, the two No. 2 electric telescopic rods are slidably connected to the two slide rails respectively, and the heads of the two No. 2 electric telescopic rods are hinged with movable pressure heads;

[0014] The above technical solution enables targeted pressing of easily delaminated areas.

[0015] Furthermore, the movable pressure head consists of two fixed blocks, a rotating shaft, and three rubber wheels, with the rotating shaft hinged to the second electric telescopic rod;

[0016] The above technical solution enables the pressure head to adhere to the rubber block when pressing the easily delaminated parts.

[0017] Furthermore, a bracket is fixed on the top of the chassis, and multiple pressing piston sleeves are fixed on the bottom surface of the bracket.

[0023] 1. The present invention proposes a shoe sole pressing machine, which adds a sliding telescopic rod to the easily separated parts of the shoe toe and heel to enhance the pressing effect, reduce the possibility of separation of the easily separated parts, and extend the service life of the shoes. At the same time, the rotation of the movable pressing head and rubber wheel during the pressing process can make the pressing head fit the rubber block more closely, the extrusion pressure is more uniform, and the possibility of wrinkles is reduced.

[0024] 2. The present invention proposes a shoe sole pressing machine, which uses a rubber plate, steel balls and a telescopic rod at the bottom. The telescopic rod extends to push the steel balls, which, together with the rubber plate, adhere to the surface of the shoe sole. This allows for the matching of soles of different types of shoes, such as flat shoes, Martin boots, and sports shoes, to work with the pressing head above for pressing. The pressing effect is more compact and reliable, and there is no need to change the mold. Attached Figure Description
