Description

Technical Field

[0001] This invention relates to a multi-angle shoe upper polishing machine and its working method. Background Technology

[0002] Leather shoes refer to footwear made with natural leather uppers and soles made of leather, rubber, plastic, PU foam, PVC, etc., processed through stitching, gluing, or injection molding. After processing, leather shoes require surface polishing to improve their gloss. In view of this, patent application number 202222905251.7 discloses a shoe upper polishing device. However, the aforementioned prior art cannot adjust the position of the polishing wheel, making it difficult to apply to polishing shoes of various sizes. Furthermore, it cannot adjust the angle of the polishing wheel during polishing, and the shoe is fixed by an external clamping mechanism during grinding, preventing adjustment of the shoe's rotation angle, thus hindering the achievement of comprehensive shoe polishing.

The clamping slide B42 is rotatably connected to one end of the clamping screw B43. The other end of the clamping screw B43 is fixed with the clamping stop B44. The clamping gear seat B45 is fixed on the clamping slide B42.

[0062] Specifically, the working method of the multi-angle shoe polishing machine is as follows: the distance between the top-tightening slide B42 and the clamping slide B32 is adjusted according to the specifications of different shoes. During adjustment, the top-tightening screw B43 is rotated to adjust the distance between the top-tightening slide B42 and the clamping slide B32. The clamping guide rod B33 is pulled to place the shoe between the top-tightening slide B42 and the clamping slide B32. The moving motor B13 drives the moving screw B14 to rotate, so that the moving slider B12 drives the moving slide B11 to move, and moves the rotating disk B23 to below the polishing mechanism A.

[0063] According to the different shoe specifications, the position of the polishing machine body A6 on one forward adjustment component A31 and two lateral adjustment components A32 is adjusted. During adjustment, the forward rotation positioning wheel A41 drives the positioning shaft A43 to move inward through the positioning bushing A42, thereby separating the positioning shaft A43 from the lateral adjustment carriage A323.

[0064] At this time, the adjustment control handle A333 can be rotated along the adjustment control shaft A331, and the positive adjustment rack A314 can be driven by the adjustment control gear A332, which in turn can drive the positive adjustment slide A313 to move along the positive adjustment slide rod A311.

[0065] While rotating the adjustment control handle A333 along the adjustment control shaft A331, the two lateral adjustment sleeves A324 are driven to move inward or outward synchronously through the adjustment control shaft A331. In turn, the lateral adjustment slide A323 can be moved along the lateral adjustment slide rod A321 through the lateral adjustment sleeves A324.

[0066] After adjusting the position of the polishing machine body A6 on one forward adjustment component A31 and two lateral adjustment components A32, the positioning wheel A41 is rotated in the opposite direction to drive the positioning shaft A43 to move outward through the positioning bushing A42. At the same time, the positioning shaft A43 contacts the lateral adjustment slide A323 to achieve the positioning of the adjustment control handle A333. When the positioning shaft A43 moves, the positioning shaft A43 is restricted from moving along its axial direction by the limiting slide groove A51 and the limiting slide rod A52.

[0067] The lifting slide A12 is driven to move up and down by the lifting cylinder A13, the swing support A22 is driven to swing by the swing cylinder A23, and the polishing wheel A62 is driven by the polishing motor A61 to achieve the polishing process of the shoe.

[0068] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components, etc. The above description is merely illustrative of the structure of the present invention.

The adjustment control gear (A332) is fixed in the middle of the adjustment control shaft (A331) and meshes with the positive adjustment rack (A314). One end of the adjustment control handle (A333) is fixed to the adjustment control gear (A332).

7. The multi-angle shoe upper polishing machine according to claim 6, characterized in that: The positioning mechanism (A4) includes a positioning wheel (A41), a positioning bushing (A42), and a positioning shaft (A43). The positioning wheel (A41) is rotatably mounted on the other end of the adjustment control handle (A333). A positioning bushing (A42) is fixed on each side of the positioning wheel (A41). The two positioning bushings (A42) are connected to the two positioning shafts (A43) respectively through positive and negative threads. The two positioning shafts (A43) abut against the two lateral adjustment slides (A323) respectively.

8. The multi-angle shoe upper polishing machine according to claim 7, characterized in that: The limiting mechanism (A5) includes a limiting groove (A51), a limiting rod (A52), and a limiting sleeve (A53). The limiting groove (A51) is disposed on the positioning rotating shaft (A43). The limiting rod (A52) is L-shaped. One end of the limiting rod (A52) is located in the limiting groove (A51), and the other end of the limiting rod (A52) is fixed to the limiting sleeve (A53). The limiting sleeve (A53) is fixed to the adjusting control handle (A333), and the limiting sleeve (A53) is fitted outside the positioning bushing (A42).

9. The multi-angle shoe upper polishing machine according to claim 8, characterized in that: The polishing machine body (A6) includes a polishing motor (A61) and a polishing wheel (A62). The polishing motor (A61) is mounted on a forward adjustment slide (A313) and a lateral adjustment slide (A323), and the polishing wheel (A62) is mounted on the motor shaft of the polishing motor (A61).

10. A method for operating a multi-angle shoe upper polishing machine as described in claim 9, characterized in that: The working method is as follows: the distance between the top-tightening slide (B42) and the clamping slide (B32) is adjusted according to the specifications of different shoes. During adjustment, the top-tightening screw (B43) is rotated to adjust the distance between the top-tightening slide (B42) and the clamping slide (B32). The clamping guide rod (B33) is pulled to place the shoe between the top-tightening slide (B42) and the clamping slide (B32). The moving motor (B13) drives the moving screw (B14) to rotate, so that the moving slider (B12) drives the moving slide (B11) to move, and moves the rotating disk (B23) to below the polishing mechanism (A). According to the different shoe specifications, the position of the polishing machine body (A6) on one forward adjustment component (A31) and two lateral adjustment components (A32) is adjusted. During adjustment, the forward rotation positioning wheel (A41) drives the positioning shaft (A43) to move inward through the positioning bushing (A42), and at the same time, the positioning shaft (A43) is separated from the lateral adjustment carriage (A323). At this time, rotate the adjustment control handle (A333) along the adjustment control shaft (A331), and drive the positive adjustment rack (A314) through the adjustment control gear (A332), which in turn drives the positive adjustment slide (A313) to move along the positive adjustment slide rod (A311) through the positive adjustment rack (A314); While rotating the adjustment control handle (A333) along the adjustment control shaft (A331), the two lateral adjustment sleeves (A324) are driven to move inward or outward synchronously through the adjustment control shaft (A331), and then the lateral adjustment slide (A323) is driven to move along the lateral adjustment slide rod (A321) through the lateral adjustment sleeves (A324); After adjusting the position of the polishing machine body (A6) on one forward adjustment assembly (A31) and two lateral adjustment assemblies (A32), the positioning wheel (A41) is rotated in the opposite direction to drive the positioning shaft (A43) to move outward through the positioning bushing (A42), so that the positioning shaft (A43) contacts the lateral adjustment carriage (A323) to achieve positioning of the adjustment control handle (A333). When the positioning shaft (A43) moves, the positioning shaft (A43) is restricted from moving along its axial direction by the limiting slide groove (A51) and the limiting slide rod (A52). The lifting slide (A12) is driven to move up and down by the lifting cylinder (A13), the swing support (A22) is driven to swing by the swing cylinder (A23), and the polishing wheel (A62) is driven by the polishing motor (A61) to achieve the polishing process of the shoe.
