Description

Technical Field

[0001] This utility model relates to the field of slipper manufacturing technology, and more specifically, to a slipper sole pressing machine. Background Technology

[0002] The sole press machine plays a crucial role in the production of bonded slippers (i.e., slippers where the sole and upper are bonded together with glue). It refers to a mechanical device that firmly bonds the upper and sole together under pressure, temperature (and time control) conditions.

[0003] Traditional sole pressing machines still have some drawbacks. Traditional molds use complex structures such as bolt fixation, making it time-consuming and labor-intensive to change slipper molds, and unable to quickly adapt to small-batch, multi-style orders. Traditional sole pressing machines lack an automatic slipper collection mechanism, requiring manual removal of slippers after pressing, resulting in low production efficiency. Furthermore, the fixed location of traditional pressing machines prevents flexible adjustments to the production line layout based on order changes. Therefore, there is an urgent need to design a sole pressing machine for slippers to solve these problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a slipper pressing machine to solve the technical problems mentioned in the background art, such as the time-consuming and labor-intensive mold replacement of traditional pressing machines and the need for manual removal of slippers after pressing, which leads to reduced efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A slipper sole pressing machine includes a lower base, an upper base, a pressing mechanism, and an automatic material receiving mechanism. The lower base has a worktable on its upper surface, and vertical plates are located at both ends of the upper surface of the worktable. The upper base is located on the upper surface of the vertical plates. The pressing mechanism has two sets, including a first hydraulic cylinder, a mounting base, a mold, and a quick-release assembly. The first hydraulic cylinder is located on the side of the vertical plate, and its telescopic end has a mounting base. The mold is detachably connected to the mounting base via the quick-release assembly. The automatic material receiving mechanism includes a second hydraulic cylinder, a slider, a third hydraulic cylinder, a shoe rack, and a rotating assembly. The second hydraulic cylinder is located inside the upper base, and the slider is slidably connected to the upper base. The telescopic end of the second hydraulic cylinder is connected to the side wall of the slider. The third hydraulic cylinder is located inside the slider, and its telescopic end is hinged to the shoe rack.

[0009] This invention is further configured such that the quick-release assembly includes a push rod, a spring, a locking block, a locking ring, a sleeve, and a slide rod. The mold sidewall has two sets of locking rings, and the mounting base surface has a groove. Two sets of push rods are provided, slidably connected within the groove. The sidewall of each push rod has a locking block adapted to the locking ring. A spring is provided between the two sets of push rods. One end of the sleeve is fixedly connected to the sidewall of one set of push rods, and the other end is slidably connected to the slide rod. The other end of the slide rod is fixedly connected to the sidewall of the other set of push rods. Manually pressing the two sets of push rods inward overcomes the spring force, causing the locking block to disengage from the locking ring, allowing the mold to be removed. The sleeve and slide rod make the push rod movement more stable, enabling quick mold disassembly and replacement, thereby improving production efficiency.

[0010] The present invention is further configured such that the rotating assembly includes a motor, a fixed plate, and a chain. The fixed plate is sleeved on the telescopic end of the third hydraulic cylinder, and the upper surface of the fixed plate is provided with a motor. The output end of the motor and the hinge shaft of the shoe rack are both connected to sprockets. The motor is connected to the shoe rack via the chain. The motor drives the hinge shaft of the shoe rack to rotate via the chain, and the shoe rack reverses to a certain tilt angle. The slippers automatically slide down to the rear conveyor belt due to gravity, eliminating the need for manual removal and improving production efficiency.

[0011] The present invention is further configured such that the side wall of the slider is provided with two sets of slide bars, and the inner side wall of the upper base is provided with a slide groove, wherein the slide bars are embedded in the slide groove and slidably connected to the slide groove. The slide bars and the slide groove form a stable guide rail, ensuring that the slider moves horizontally without deviation.

[0012] The present invention is further configured such that a control console is provided on the surface of the lower base. The control console controls the overall operation of the device.

[0013] This invention is further configured such that the lower end face of the lower machine base is provided with four sets of universal wheels. These universal wheels allow for the movement of equipment, facilitating adjustments to the production line layout and adapting to multiple batches of small-volume orders.

[0014] The present invention is further configured such that the moving end of the slide bar abuts against the inner side wall of the sleeve end, thereby limiting the maximum stroke of the push rod and playing a limiting role.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sole pressing machine for slippers, which has the following beneficial effects:

[0017] 1. This utility model is equipped with a pressing mechanism. Through the coordinated operation of the first hydraulic cylinder and the mold, the sole and upper of the slipper are pressed together. When the mold needs to be disassembled, the two sets of push rods are manually pressed inward to overcome the spring force and make the locking block disengage from the locking ring, so that the mold can be removed. When the mold needs to be replaced for installation, the two sets of push rods are manually pressed inward to align the locking ring of the mold with the locking block. The push rods are released, and the spring pushes the push rods to make the locking block automatically lock the locking ring, so as to quickly replace the mold to adapt to different types of slippers.

[0018] 2. This utility model is equipped with an automatic material receiving mechanism. After the pressing is completed, the third hydraulic cylinder drives the shoe rack to move upward. Then, the second hydraulic cylinder pushes the slider to move horizontally along the slide groove to move the shoe rack out of the pressing area. The motor drives the hinge shaft of the shoe rack to rotate through the chain. The shoe rack reverses to a certain tilt angle. The pressed slippers automatically slide down to the rear conveyor belt due to gravity, without the need for manual picking, thus improving production efficiency.

[0019] 3. This utility model is equipped with four sets of universal wheels, which can be used to move equipment, making it easy to adjust the production line layout and adapt to multiple batches of small orders. Attached Figure Description
