Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking equipment, in particular to a mechanical device used for pressing the upper and sole of leather shoes. Background Art

[0002] The lamination of uppers and soles of leather shoes is a crucial step in the production process of leather shoes, which directly determines the overall quality and service life of leather shoes. In the production process of leather shoes, the use of upper and sole laminating machines can greatly improve production efficiency. Through automated operation, the laminating process can complete the lamination of multiple pairs of shoes in a short time, which significantly improves efficiency compared to traditional manual operations.

[0003] However, the existing upper and sole pressing machines for leather shoes can usually only press the heels and toes when in use. If it is a flat leather shoe, the upper and sole can be effectively pressed together. If the upper and sole of a wedge-heeled leather shoe are pressed together, the middle part of the sole cannot be effectively supported and pressed, which may easily cause the middle part of the sole to be unable to be firmly bonded to the upper. Therefore, a mechanical device for pressing the upper and sole of leather shoes is proposed. Utility Model Content

[0022] like Figures 1 to 3As shown, a mechanical device for pressing the upper and sole of leather shoes comprises a pressing chamber 1, which is a U-shaped structure. A mounting frame 2 is fixedly installed on the top of the pressing chamber 1, and a liftable guide rail 3 is arranged inside the mounting frame 2. A first pressing head 4, a second pressing head 5, and a third pressing head 6 are slidably installed on the guide rail 3. Double-headed cylinders 7 are fixedly installed on both sides of the pressing chamber 1, and U-shaped frames 8 are respectively sleeved on the two ends of the top of the pressing chamber 1. The two output ends of each double-headed cylinder 7 are fixedly connected to the adjacent U-shaped frames 8, and a positioning plate 9 that can be adjusted to rise and fall is arranged on each U-shaped frame 8. A groove 10 is provided on the inner bottom surface of the pressing chamber 1, and a rotatable rotating shaft 11 is movably installed inside the groove 10, and an E-shaped frame 12 is fixedly installed on the side wall of the rotating shaft 11, and a driving component 13 for adjusting the inclination angle of the E-shaped frame 12 is arranged inside the groove 10. It should be noted that the shoe upper and sole that are initially bonded are first placed on the inner bottom surface of the pressing chamber 1. The shoe upper is filled with a mold at this time. If the sole is a wedge heel, the staff adjusts the inclination angle of the E-shaped frame 12 according to the slope of the sole, specifically by controlling the inclination angle of the E-shaped frame 12 adjustable by the driving assembly 13, and then aligns the middle position of the sole with the E-shaped frame 12, so that the sole and the E-shaped frame 12 are placed in close contact. At this time, the front and back of the sole are respectively in contact with the inner bottom surface of the pressing cavity 1, and the toe is located directly below the first pressing head 4, and then the two double-headed cylinders 7 are started to make the two U-shaped frames 8 and the two positioning plates 9 close to each other to position the leather shoes, and then the guide rail 3 is started to drive the first pressing head 4, the second pressing head 5, and the third pressing head 6 to move downward, and the first pressing head 4, the second pressing head 5, and the third pressing head 6 are used to press simultaneously from the front and back and the middle position of the leather shoes, the third pressing head 6 is mainly pressed from the middle position, and the E-shaped frame 12 is mainly supported from the middle position of the sole, so that the upper and the sole can be pressed together more firmly.

[0023] like Figures 1 to 3 As shown, the driving assembly 13 includes a groove 1301, the inner bottom surface of the groove 10 is provided with a groove 1301, and the inner side walls of the groove 1301 are respectively movably mounted with a rotatable shaft 1303, and a telescopic cylinder 1302 is fixedly mounted between the two shafts 1303.

It should be noted that the extension of the telescopic cylinder 1302 can increase the inclination angle of the E-shaped frame 12, and the contraction of the telescopic cylinder 1302 can reduce the inclination angle of the E-shaped frame 12. The telescopic cylinder 1302 will drive the shaft 1 1303 and the shaft 2 1305 to rotate in coordination while extending and contracting.

[0024] like Figure 2 , Figure 3As shown, three trapezoidal grooves 14 are provided on the top of the E-shaped frame 12, and a trapezoidal rod 15 is movably installed inside each trapezoidal groove 14. A connecting rod 16 is provided on the side of the E-shaped frame 12 away from the rotating shaft 11, and the connecting rod 16 is fixedly connected to each trapezoidal rod 15. A threaded hole 17 is provided on the inner wall surface of each trapezoidal groove 14, and a bolt 18 is threadedly connected inside each threaded hole 17. It should be noted that the staff can choose to pull the connecting rod 16 according to the size of the shoe upper slope, and use the connecting rod 16 to drive the three trapezoidal rods 15 to slide to the appropriate position inside the corresponding trapezoidal groove 14, and then rotate the three bolts 18 to fix the current position of the three trapezoidal rods 15, so that it can be suitable for shoe sole slopes of larger sizes.

A number of equidistantly distributed cylinders 21 are respectively fixedly installed on the side walls of the pressing chamber 1, and the output end of each cylinder 21 extends to the inside of the adjacent groove 3 20, and the output end of each cylinder 21 is fixedly connected to the adjacent supporting plate 22. It should be noted that when pressing the flat sole and upper, the inclination angle of the E-shaped frame 12 is first adjusted to the minimum, and then each cylinder 21 is started, and each cylinder 21 drives the corresponding supporting plate 22 to move toward the middle. When the two supporting plates 22 are in contact with each other, the sole and the upper can be placed on the top of the two supporting plates 22 for pressing.

The two positioning plates 9 are provided with a plurality of longitudinally equidistantly distributed tapping holes 24 on the side close to each other, and the two U-shaped frames 8 are provided with screw holes 25 on the side close to each other. The inside of each screw hole 25 is threadedly connected with a screw 26, and the tail end of each screw 26 is threadedly connected to the inside of the adjacent tapping hole 24. It should be noted that when the two supporting plates 22 are pressed together, the two positioning plates 9 can be pulled upward to a suitable height, and then the tail end of each screw hole 25 can be threadedly connected to the inside of the adjacent screw 26, so that the bottom of the two positioning plates 9 is aligned with the top of the supporting plate 22, and the two positioning plates 9 can be used to position the sole and the upper during the pressing process.

[0028] In summary:

[0029] First, the preliminary bonded upper and sole are placed on the inner bottom surface of the pressing cavity 1. At this time, the upper is filled with a mold. If the sole is a wedge heel, the staff adjusts the inclination angle of the E-shaped frame 12 according to the slope of the sole, specifically by controlling the inclination angle of the E-shaped frame 12 adjustable by the driving component 13, and then aligns the middle position of the sole with the E-shaped frame 12, so that the sole and the E-shaped frame 12 are placed in close contact. At this time, the front and rear parts of the sole are respectively in contact with the inner bottom surface of the pressing cavity 1, and the toe is located at the first pressing head 4. Directly below, two double-headed cylinders 7 are then started to make the two U-shaped frames 8 and the two positioning plates 9 approach each other to position the leather shoes, and then the guide rail 3 is started to drive the first pressing head 4, the second pressing head 5, and the third pressing head 6 to move downward, and the first pressing head 4, the second pressing head 5, and the third pressing head 6 are used to press the leather shoes from the front and back and the middle position at the same time, and the third pressing head 6 is mainly pressed from the middle position, and the E-shaped frame 12 is mainly supported from the middle position of the sole, so that the upper and the sole can be pressed together more firmly.
