Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a shoe upper oil-based adhesive spraying machine. Background Technology

[0002] Adhesive spraying is one of the important processes in the shoe manufacturing industry. Components such as the toe box and upper need to be glued together. The quality of the adhesive spraying determines the strength of the bond between the upper and the sole, which in turn affects the performance and quality of the shoes.

[0003] CN215088440U discloses a glue spraying device for slipper production, including a cabinet and a recycling mechanism located at the top of the cabinet. The recycling mechanism includes a heating plate with glue flow holes on its surface and glue spraying wires at the upper ends of the flow holes. The recycling mechanism is used to collect glue that has not adhered to the slippers during the spraying process. A glue spraying assembly is located at the top of the recycling mechanism, including a glue spraying roller with rotating shafts connected to both sides. A side protective plate is fixedly connected to the top of the cabinet, and a glue spraying plate is fixedly connected to the upper part of the side protective plate. The glue spraying assembly includes a housing, which is bolted to the upper part of the glue spraying plate. A rotating shaft is fixedly connected to the lower end of the housing, and a glue spraying nozzle is fixedly connected to the outer side of the glue spraying roller. This equipment is mainly for spraying glue onto flat surfaces and is not suitable for spraying glue onto the inner side of the shoe upper.

[0004] For some shoe uppers that are made of a single piece, it is necessary to spray adhesive on the edges of the upper to ensure stable adhesion to the sole. The traditional method for spraying adhesive on the upper involves manually turning the shoe over so that the inner side is exposed and the patterned outer side is concealed. Then, workers apply adhesive to the exposed inner side. This method requires a high level of skill from the workers, and during the application process, the workers' hands easily become covered in oily adhesive, which not only affects their health but also causes the oily adhesive from their hands to adhere to the patterned outer side, resulting in product defects. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a shoe upper oil-based adhesive spraying machine. This spraying machine can prevent oil-based adhesive from adhering to the workers' hands during the spraying process, and also reduces the adhesion of oil-based adhesive to the outer surface with patterns, thereby improving the yield rate of production.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] refer to Figures 1-4 A shoe upper oil-based adhesive spraying machine includes a machine housing 1, an adhesive spraying mechanism 2 disposed on the machine housing 1, and a positioning mechanism 3 disposed on the machine housing 1; the adhesive spraying mechanism 2 is arranged directly above the positioning mechanism 3 and is used to spray oil-based adhesive onto the inner side of the shoe upper a; the positioning mechanism 3 includes a first rotating shaft 31 and a second rotating shaft 32; the shoe upper a is fitted into the first rotating shaft 31 and the second rotating shaft 32, and the first rotating shaft 31 and the second rotating shaft 32 are respectively used to contact one end of the shoe upper a to open the shoe upper a.

[0026] In practical application, the worker flips the shoe upper a so that the inner side of the shoe upper a is exposed, while the patterned outer side is concealed. Then, the first rotating shaft 31 and the second rotating shaft 32 of the positioning mechanism 3 are used to position the toe part and the heel part of the shoe upper a, respectively. Then, the pneumatic glue spraying mechanism 2 starts to apply glue. During the glue application process, the worker holds the shoe upper a and pulls it away from the area to be sprayed. The first rotating shaft 31 and the second rotating shaft 32 rotate accordingly, so that the edges of the shoe upper a enter the working area of ​​the glue spraying mechanism 2 to complete the glue application. Finally, the shoe upper a is gently pushed out.

[0027] In this embodiment, the first rotating shaft 31 on the positioning mechanism 3 fixes both ends of the shoe upper a, eliminating the need for workers to hold the shoe upper a by hand. Then, the glue spraying mechanism 2 applies the glue. During the spraying process, the worker continuously adjusts the application area, automatically applying glue to the inner edge of the shoe upper a. This not only improves glue application efficiency and prevents oily glue from adhering to the worker's hands during spraying, but also reduces the amount of oily glue adhering to the patterned outer surface, thus increasing the yield rate of production.

[0028] In this embodiment, specifically, the positioning mechanism 3 further includes a mounting base 33; the first rotating shaft 31 and the second rotating shaft 32 are disposed on the mounting base 33; preferably, the mounting base 33 is provided with a vertical first through groove 331 and a horizontal second through groove 332; the first rotating shaft 31 is movably connected to the first through groove 331; the second rotating shaft 32 is movably connected to the second through groove 332.

[0029] Under the above design, the positioning mechanism 3 of this embodiment can be applied to the production of shoe uppers a of different sizes. It is only necessary to adjust the relative position of the first rotating shaft 31 and the second rotating shaft 32. It should be noted that when adjusting the relative position of the first rotating shaft 31 and the second rotating shaft 32, the shoe upper a should not be fully tensioned. A certain gap should be left to prevent the shoe upper a from being unable to rotate.

[0030] In this embodiment, preferably, the glue spraying mechanism 2 includes a fixed plate 21 mounted on a frame, a nozzle 22 mounted on the fixed plate 21, and a glue storage tank for providing oil-based glue; the nozzle 22 is arranged directly above the positioning mechanism 3 and is used to spray glue onto the shoe upper a. Of course, in practical applications, an air source is also required to spray the oil-based glue. Since the glue spraying mechanism 2 is a well-known technical means, such as the structure disclosed in CN111013885A, this embodiment will not describe the glue spraying mechanism 2 in detail, and the components are not specifically marked in the accompanying drawings.

[0031] As a preferred embodiment, in order to facilitate operation by staff and improve operability, the glue spraying mechanism 2 further includes a foot pedal controller 23 for controlling the operation of the spray nozzle 22.

[0032] In this preferred embodiment, the nozzle 22 is movably connected to the fixed plate 21. In practical applications, depending on the pressure and spraying range of the nozzle 22, the operator can adjust the nozzle 22 up and down to change the distance from the positioning mechanism 3, thereby adapting the nozzle 22 or the preferred spraying range.

[0033] In this embodiment, in order to prevent the first pivot 31 and the second pivot 32 from damaging the pattern of the shoe upper a, the surfaces of the first pivot 31 and the second pivot 32 are provided with a flexible protective layer (not shown in the figure).

[0034] As a further preferred embodiment, in order to facilitate the movement of the machine by the staff, the bottom of the chassis 1 is provided with a plurality of sliding wheels 11 for easy transportation.
