Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a uniform pressing device for shoe soles and uppers. Background Technology

[0002] In the shoe manufacturing process, the bonding process between the sole and the upper is a crucial step, as the quality of the bonding directly affects the product's quality, appearance, and lifespan. The bonding process mainly relies on manual operation: First, workers apply adhesive to the top perimeter of the inner side of the sole and the bottom perimeter of the outer side of the upper (which is fitted with a shoe last). Then, the upper is placed on the sole and aligned. Using a tool, pressure is applied to the bonding area between the sole and upper by hand and held for a period of time to allow the adhesive to initially cure and set. Finally, the shoe is placed in a heating device to further cure the adhesive.

[0003] Traditional manual pressing operations struggle to ensure uniform pressing force, easily leading to poor localized bonding. Currently, many pressing machines for shoe soles and uppers are available on the market. These machines typically feature a contour-following front and rear pressing mechanism, achieving shoe bonding through front and rear pressure. While these machines are more efficient than previous methods, the uneven height of shoes, especially at the toe, can cause uneven pressure and shoe deformation, impacting production quality. Existing shoe sole and upper pressing equipment usually requires manual application of glue before pressing, resulting in low efficiency. Furthermore, these machines typically press a large area of ​​the shoe, making it difficult to adjust the front and rear pressing positions according to shoe size, limiting their application and causing uneven pressure. Therefore, we propose a uniform pressing device for shoe soles and uppers. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1 This utility model provides a technical solution: a uniform pressing device for shoe soles and uppers, including a support platform 1, a support frame 2 installed on the top of the support platform 1, and a controller installed at the top of the support frame 2. Shoe sole and upper pressing mechanisms 4 are symmetrically arranged inside the support frame 2. Placement platforms 3 for placing shoes are provided on the top of the support platform 1 below the shoe sole and upper pressing mechanisms 4. The shoe sole and upper pressing mechanism 4 includes a U-shaped plate 12, and hydraulic cylinders 15 with adjustable spacing are symmetrically arranged inside the U-shaped plate 12. A retractable lower pressure plate 11 is installed at the piston rod end of the hydraulic cylinder 15. A conveying platform 6 is provided on the side wall of the support platform 1, and upright plates 7 are symmetrically fixed to the top of the conveying platform 6. An adjustable-height glue roller 8 for applying glue to the shoe sole is arranged between the two upright plates 7.

[0022] It should be noted that by setting the height-adjustable glue-applying roller 8, it can adapt to applying glue to shoe soles of different thicknesses. The conveyor table 6 can transport the shoe soles on it. When the shoe sole passes through the glue-applying roller 8, the glue-applying roller 8 can evenly apply glue to the surface of the shoe sole. The dual-station shoe sole and shoe upper pressing greatly improves the pressing efficiency of the shoe sole and shoe upper.

[0023] Please see Figure 3 A U-shaped plate 12 is symmetrically fixed to the top of the inner wall of the support frame 2, and a bidirectional screw 13 is rotatably connected between the two corresponding inner walls of the U-shaped plate 12 through a bearing. The two ends of the bidirectional screw 13 are symmetrically threaded to sliders. Two hydraulic cylinders 15 are respectively fixed to the bottom of the two sliders. A sleeve 16 is fixed to the end of the piston rod of the hydraulic cylinder 15, and a lifting screw 17 is slidably arranged inside the sleeve 16. A threaded sleeve 18 is rotatably connected to the bottom of the sleeve 16, and the lifting screw 17 is threadedly connected inside the threaded sleeve 18.

[0024] It should be noted that by controlling the rotation of the bidirectional screw 13, the distance between the two sliders can be adjusted, thereby adjusting the distance between the two hydraulic cylinders 15. The lifting screw 17 is threadedly connected inside the threaded sleeve 18 and is slidably disposed inside the sleeve 16. When the threaded sleeve 18 is rotated, the lifting screw 17 can be raised or lowered, thereby adjusting the height of the lower pressure plate 11. The height of the two lower pressure plates 11 is adjustable, and the height difference between the two lower pressure plates 11 can be adjusted according to different shoes, so that the lower pressure plates 11 and the sponge block 14 correspond to the two ends of the foot mold respectively, so that the pressure is applied to the foot mold. The foot mold evenly presses down on the sole and upper of the shoe, so that the shoe is bonded with high quality.

[0025] Please see Figure 1 and Figure 2 The top of the placement platform 3 is provided with a fixing groove, and a support base 26 is connected in the fixing groove. A sponge support pad is provided in the support base 26. A locking bolt 5 is provided at one end of the placement platform 3. A locking hole is provided on the side wall of the support base 26. The end of the locking bolt 5 is threaded into the locking hole of the support base 26.

[0026] It should be noted that, in use, the height of the gluing roller 8 is adjusted according to the thickness of the sole, and the distance between the two lower pressure plates 11 and the sponge block 14 is adjusted according to the size of the shoe to be pressed, so that the lower pressure plate 11 can press down at the shoe opening and the sponge block 14 can press down at the toe. The distance between the control roller 9 and the gluing roller 8 is adjusted, and the sole to be glued is conveyed through the conveyor table 6. During the conveying process, the glue is applied to the surface of the sole by the gluing roller 8. When conveying to the paper support table 1, the shoe upper with the foot mold is manually removed, aligned and glued to the sole, and then placed on the support seat 26. The position of the lower pressure plate 11 and the sponge block 14 is adjusted by the height of the foot mold relative to the shoe upper. During adjustment, only the threaded sleeve 18 needs to be rotated. The height difference between the lower pressure plate 11 and the sponge block 14 is adjusted through the threaded connection between the upright plate 7 and the threaded sleeve 18. Tighten the fastening bolt 10, and the lower pressure plate 11 is pressed down to the foot mold position and the sponge block 14 is pressed down to the toe position by the working control of the hydraulic cylinder 15. A pressure gauge is set at the top of the support platform 1, and a pressure sensor is installed at the bottom of the lower pressure plate 11 to control the pressure of the downward press. The lower pressure plate 11 and the sponge block 14 press down on the foot mold, and the foot mold fits inside the shoe to achieve uniform pressing of the sole and the upper.

[0027] Please see Figure 2The upright plate 7 has a lifting groove, and a lifting block 20 is slidably arranged in the lifting groove. The two ends of the glue roller 8 are rotatably connected to the surface of the lifting block 20 through bearings. A slide rod 21 is fixed to the top of the lifting block 20, and the end of the slide rod 21 slides through the upright plate 7. The top of the slide rod 21 is provided with an external thread, and a nut is threaded to the end of the slide rod 21 located at the external thread. A spring 22 is sleeved inside the upright plate 7 on the outside of the slide rod 21.

[0028] It should be noted that an external thread is provided at the upper end of the slide bar 21. By rotating the nut, the height of the lifting block 20 can be adjusted to a certain extent, so that the sole can be better coated with glue when passing through the glue coating roller 8. The spring 22 provides a certain buffering effect, allowing the glue coating roller 8 to press down on the sole and achieve uniform glue application.

[0029] Please see Figure 2 The corresponding side walls of the upright plate 7 are provided with sliding grooves. The end of the lifting block 20 passes through the sliding groove and is fixedly connected to the fixing plate 23. The fixing plate 23 is provided with a rectangular groove, and a slide seat 24 is slidably connected in the rectangular groove. The two ends of the control roller 9 are respectively rotatably connected to the surfaces of the two slide seats 24 through bearings. The side of the slide seat 24 away from the upright plate 7 is rotatably connected to the threaded rod 25 through the bearing. The end of the fixing plate 23 is provided with a threaded hole, and the threaded rod 25 is threadedly connected in the threaded hole. A rotating wheel is provided at the end of the threaded rod 25 located outside the fixing plate 23.

[0030] It should be noted that the rotation of the rotating wheel can control the rotation of the threaded rod 25, thereby adjusting the position of the slide block 24 in the sliding groove, and thus adjusting the distance between the control roller 9 and the glue coating roller 8. The control roller 9 can adjust the thickness of the glue on the glue coating roller 8 to prevent the glue from being too thick in some areas.

[0031] Please see Figure 1 The top of the inner wall of the support frame 2 along the length of the U-shaped plate 12 and the surface of the support frame 2 along the vertical direction are both provided with length scales.

[0032] It should be noted that the length scale setting facilitates the adjustment of the height difference between the lower pressure plate 11 and the sponge block 14, thereby enabling the lower pressure plate 11 and the sponge block 14 to press down on the foot mold side and the foot mold end.

[0033] Please see Figure 3 The outer side of the sleeve 16 is symmetrically provided with limiting grooves. The outer side of the lifting screw 17 located inside the sleeve 16 is symmetrically provided with limiting blocks 19, and the limiting blocks 19 are slidably connected in the limiting grooves.

The bottom of the lower pressure plate 11 at one end of the U-shaped plate 12 is provided with a sponge block 14. The bottom end of the sleeve 16 is provided with a fastening bolt 10. The outer side of the lifting screw 17 is provided with fixing holes at equal intervals. The end of the fastening bolt 10 is threaded into the fixing hole.

[0034] It should be noted that this setting can adjust the position of the lower pressure plate 11 and the sponge block 14 according to the height position of the foot mold's upper and the shoe upper. When adjusting, only the threaded sleeve 18 needs to be rotated, and the height difference between the lower pressure plate 11 and the sponge block 14 can be adjusted through the threaded connection between the upright plate 7 and the threaded sleeve 18, and the fastening bolt 10 can be tightened.

[0035] Please see Figure 3 One end of the bidirectional screw 13 passes through the U-shaped plate 12 and is fixed to a rotating disk. A limit rod is symmetrically fixed inside the U-shaped plate 12 on the outside of the bidirectional screw 13. Limit holes are symmetrically opened on the surface of the slider inside the U-shaped plate 12. The limit rod inside the U-shaped plate 12 is slidably connected inside the limit hole of the slider.
