Description

Technical Field

[0001] The utility model relates to the technical field of disposable slippers, in particular to a powder applying mechanism for the soles of slippers. Background Art

[0002] Disposable slippers are mainly used in hotels, beauty salons, dust-free workshops, etc. because of their low price, convenience, and sanitation. Disposable slippers are mainly composed of a sole and an upper. At present, the production of disposable slippers has developed from traditional manual and semi-automatic to automated production. The automated production equipment of disposable slippers is also in a continuous development process. In the production process of existing disposable slippers, the sole fabric is generally processed, and then it is combined with the processed upper on the other side and welded or bonded to complete the overall processing of the slippers.

[0003] Among them, in the process of bonding the sole and the upper, usually the surface of the sole is first coated with glue through a gluing device, and then the processed upper is transported over and fixed on the sole, and the sole and the upper are bonded together with the coated glue to form a complete slipper.

[0004] For example, the Chinese invention patent "A disposable slipper sole gluing and curing device" with application number 202410041896.1 (application publication number CN117598566 A) discloses a similar automatic gluing device, which includes a frame, a gluing frame is arranged in the frame tube, a driving assembly is arranged on one side of the gluing frame, a rolling roller is connected to the output end of the driving assembly, and a glue-coating cylinder is arranged on one side of the rolling roller, a conveying wheel is arranged at the bottom of the glue-coating cylinder, one end of the conveying wheel is connected to a transmission mechanism, and the other end of the transmission mechanism is connected to a rotating shaft, a stirring mechanism is arranged on the outer wall of the rotating shaft, and an array of trapezoidal grooves is arranged on the glue-coating cylinder. The present invention realizes stirring and disturbing the glue in the glue-coating cylinder by the action of the stirring blade, so as to prevent the glue in the glue-coating cylinder from being stratified for a long time. When the trapezoidal block contacts the sole, the compression spring on the inner wall will be squeezed. At this time, the glue in the glue-coating cylinder will flow to the surface of the sole through the gap between the trapezoidal groove and the trapezoidal block, so as to complete the application of glue.

[0005] The glue coating technology disclosed above uses liquid glue with strong fluidity. During the coating process on the sole surface, it is difficult to ensure that the glue is evenly coated on the set position on the sole surface, and it is easy to spread to the surrounding area and affect the accuracy of the coating position. At the same time, the overflowed liquid glue can easily contaminate the sole surface and affect the subsequent curing effect, thereby reducing the final yield of the slippers.
