Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shoe sole production, in particular to a gluing device for shoe sole production. BACKGROUND

[0002] Gluing is a key process in shoe sole production. Commonly used glues include neoprene glue and polyurethane glue. Neoprene glue has good initial adhesion and water resistance, and has good bonding effect on various materials. Polyurethane glue has higher strength and flexibility, and is particularly suitable for shoe soles with high softness requirements. When selecting glue, the type of shoe sole material should be considered, such as rubber, plastic, leather, etc. Different materials require matching glue to ensure good bonding performance. For example, neoprene glue has good bonding effect on rubber soles, while polyurethane glue can better ensure the bonding strength and softness of leather soles.

[0003] Through retrieval, a gluing device for shoe sole production is disclosed in Chinese Patent No. CN 222532830 U, which comprises a pedestal, a support seat, a bearing seat, a shoe placing component, a displacement driving assembly, a telescopic driving component and a glue applying mechanism. The shoe placing component for placing the shoe sole is arranged on the bearing seat connected with the support seat, and the support seat is connected with the slide of the displacement driving assembly. When the screw component rotates under the cooperation of the driving component, the slide drives the support seat to move along the rotation direction of the screw component, thereby driving the shoe placing component to approach or move away from the glue applying mechanism located on one side of the pedestal. The telescopic driving component is arranged on one side of the support seat and connected with the bearing seat, so as to drive the bearing seat to move along the length direction of the support seat. The displacement driving assembly and the telescopic driving component can realize the movement of the shoe placing component, thereby simulating the operation of uniformly applying glue to the shoe sole by the glue applying mechanism during manual operation, and reducing the labor intensity to a certain extent.

[0004] However, the inventors have found that the above-mentioned related technology has the following disadvantages: the gluing process of the shoe sole may be uneven. If the single nozzle is not timely unblocked after being blocked, the gluing will be uneven, the unblocking of the nozzle will delay the progress of the gluing, and the uneven gluing will cause the bonding strength of each part of the shoe sole to be inconsistent, affecting the product quality. In addition, since the sizes of the shoe soles are different, the fixing of the shoe soles during the gluing process cannot be stable, resulting in the spilling of glue during the gluing process.
