Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe sole pressing machines, and in particular to a bottom pressing device for shoe sole pressing machines. Background Technology
[0002] The sole press is a key piece of equipment in the shoe manufacturing industry used to press and bond the sole and upper together. By applying pressure and temperature, it ensures that the sole and upper are firmly bonded together and is widely used in the production of various types of footwear such as sports shoes, leather shoes, and casual shoes.
[0003] Chinese patent application number 202111285980.0 discloses a shoe sole pressing machine, including a shoe sole pressing worktable arranged in a left-right direction and a shoe sole pressing component located above the worktable. A front conveyor is arranged side-by-side on the front side of the worktable, with a shoe sole edge-finishing station. A transfer robot is located above the edge-finishing station. During operation, the transfer robot picks up rubber shoes from the worktable and places them at the edge-finishing station. A corresponding edge-finishing mechanism is provided at the edge-finishing station. This invention enables fully automated shoe sole pressing production, improving efficiency, and also allows for automatic edge-finishing of the pressed soles, better ensuring shoe quality. The main improvement of the technical solution proposed in the above invention is that automatic edge-pressing can be carried out during the sole pressing process to improve the quality of the finished product. However, the connection between the sole and the upper at the bottom of the shoe has not been improved. In actual production, due to different shoe shapes, the matching soles and uppers are also different. It is difficult to adapt to different shoe shapes and achieve a complete fit using conventional sole pressing machines. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a bottom pressing device for a shoe sole pressing machine, which solves the technical problem that existing shoe sole pressing machines are unable to fully press the sole and upper from the bottom to make the two fit together completely.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bottom pressurizing device for a shoe sole pressing machine, comprising a conveying mechanism, a front and rear pressurizing and tightening mechanism, and a bottom pressurizing mechanism. The bottom pressurizing mechanism includes, from bottom to top, an air inlet plate mounting base plate, an air inlet plate, a bottom pressure rubber inner bag, and a bottom pressure rubber outer bag. The bottom pressure rubber inner bag and the bottom pressure rubber outer bag are made of elastic material that can be elastically stretched. The bottom pressurizing mechanism is connected to an external air source. Pressure strips are provided on both sides of the air inlet plate mounting base plate. A first air inlet hole and a first air outlet hole are provided on the pressure strips. A second air inlet hole and a second air outlet hole are provided on the air inlet plate mounting base plate. A third air inlet hole is provided on the air inlet plate. The bottom pressure rubber inner bag is placed on the air inlet plate, and the bottom pressure rubber outer bag is placed on the bottom pressure rubber inner bag.
[0006] Furthermore, airbag protective covers are provided on the left and right sides of the bottom pressurization mechanism, and front and rear pressure plates and airbag pressure plates are provided at the front and rear ends of the bottom pressurization mechanism.
[0007] Furthermore, the conveying mechanism includes a first conveyor belt and a second conveyor belt, which are disposed on the front and rear sides of the bottom pressurizing mechanism.
[0008] Furthermore, clamping devices are provided on both sides of the bottom pressurizing mechanism. The clamping devices include several regularly arranged clamping plates, each of which moves independently, moving closer to or further away from the bottom pressurizing mechanism.
[0009] Furthermore, the front and rear pressure clamping mechanism includes support rods arranged around the bottom pressure mechanism, a support plate arranged on the support rods, and a clamping plate arranged on the support plate. The support plate is fixedly arranged on the support rods, and the clamping plate is movably arranged on the support rods. A cylinder is arranged on the support plate, and the clamping plate is raised and lowered by the cylinder. A front clamping block and a rear clamping block are arranged on the clamping plate.
[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This utility model applies pressure to the shoe from the bottom by setting a bottom pressure mechanism, ensuring that the sole and the bottom of the upper are firmly bonded. At the same time, the bottom pressure mechanism adopts the flexible airbag inflation principle, ensuring that it can be adapted to different types of shoes. Attached Figure Description
