Description

Technical Field

[0001] The utility model relates to the technical field of leather shoe processing, and more particularly to a clamping mechanism for leather shoe processing. Background Art

[0002] Leather shoes are made of leather and are characterized by wear resistance, durability, and comfort. With diverse designs and adaptability to various occasions, leather shoes have become an indispensable fashion item in people's daily lives. During the leather shoe manufacturing process, rubber soles are typically produced through injection molding. This often results in excess ridges or machining allowances on the edges of the soles. To ensure the quality of the leather shoe soles, these ridges need to be polished and trimmed.

[0003] In the prior art, during the grinding and trimming of leather shoe soles, some grinding and trimming devices are usually not provided with a clamping mechanism, and the staff is required to hold the sole, then grind and trim the convex edge of the sole close to the grinding wheel, and then manually rotate the sole through the working rotation to complete the grinding of the convex edge on the outside of the sole. This method of manually fixing the sole will greatly increase the labor burden of the staff. At the same time, the manual grinding and trimming error is large, which affects the quality of the leather shoe sole after processing; secondly, in the prior art, even if a clamping mechanism is provided on some grinding and trimming devices, the staff is required to manually position it, that is, the staff is required to place the sole to be ground and trimmed on the placement seat, manually position the sole by moving the sole back and forth, and then clamp and fix the sole. This positioning and clamping method can easily cause inaccurate positioning of the sole, causing the sole to deviate during the grinding and trimming process, thereby increasing the generation of waste.

[0032] In this embodiment, the lower mold 11 is placed on the mounting seat 6, and the two fixing blocks 10 are placed in the two fixing grooves 12. One end of the bidirectional screw 8 passes through the drive chamber 7 and is fixedly connected to the handle 28. The handle 28 is turned, and the handle 28 drives the bidirectional screw 8 to rotate.

When the fixing block 10 is stuck in the fixing groove 12, the lower mold 11 can be installed. Different models of lower molds 11 can be replaced according to the soles of different sizes. The soles that need to be polished and trimmed are placed on the lower mold 11, and the first electric push rod is started. 3. The first electric push rod 3 drives the pressing plate 4 to move, thereby fixing the sole to the lower mold 11, starting the first motor 5, the first motor 5 drives the mounting seat 6 to rotate, and the mounting seat 6 drives the fixed sole to rotate. The pressing plate 4 will rotate around the rotating connection with the first electric push rod 3 under the drive of the sole.

The grinding and trimming component has the same structure and principle as the grinding and trimming component disclosed in the sole trimming equipment with the publication number: CN209403708U, and the patent name is: It is a disclosed prior art and will not be described in detail here.

[0033] More specifically, by rotating the handle 28, the two fixing blocks 10 are engaged in the fixing slots 12, thereby installing the lower mold 11. The first electric push rod 3 is activated to secure the sole to the lower mold 11, and the first motor 5 is activated to rotate the sole. When the sole placed on the lower mold 11 needs to be positioned, the four positioning rods 16 are moved toward the sole to position it. The positioning rods 16 then return to their original positions. After the rotating ring 15 rotates 90 degrees, the positioning rods 16 are moved again to position the sole, thereby positioning the sole in the center of the lower mold 11.

[0034] See also Figure 1-5 , as an implementation method for positioning the sole: two limiting grooves 17 are provided at the lower end of the rotating ring 15, and a screw 18 is rotatably provided in each limiting groove 17.

[0035] Specifically, the sole is placed on the lower mold 11, and the dual-axis motor 22 is started. The dual-axis motor 22 drives the two rotating rods 21 to rotate, and the rotating rod 21 drives the screw 18 to rotate through the transmission belt structure 23. The threads on the two screws 18 are in opposite directions. At the same time, since the screw 18 is threadedly connected to the positioning seat 19, the two positioning seats 19 move in adjacent directions along the limit groove 17 respectively, and the positioning seat 19 drives the positioning rod 16 to move, thereby positioning the sole placed on the lower mold 11.

[0036] See also Figure 1-5 As an implementation method for moving and rotating the rotating ring 15: two second electric push rods 24 are fixedly provided on the bracket 2, and the driving ends of the two second electric push rods 24 pass through the bracket 2 and are fixedly connected to the lifting ring 14. A toothed belt 25 is fixedly provided on the outside of the rotating ring 15, and the toothed belt 25 is meshed with a gear 26, and the gear 26 is fixedly connected to a second motor 27 fixedly provided on one side of the lifting ring 14.

At this time, the sole is positioned for the second time by the movement of the positioning rod 16.

[0038] In summary, when the overall equipment is in use:

[0039] When the lower mold 11 needs to be installed, the lower mold 11 is placed on the mounting seat 6, and the two fixed blocks 10 are placed in the two fixed grooves 12. One end of the bidirectional screw 8 passes through the drive chamber 7 and is fixedly connected to the handle 28. The handle 28 is turned, and the handle 28 drives the bidirectional screw 8 to rotate. The bidirectional screw 8 is provided with two threaded areas in opposite directions, so that the two fixed blocks 10 move away from each other. When the fixed block 10 is stuck in the fixed groove 12, the lower mold 11 can be installed. Different models of lower molds 11 can be replaced according to the soles of different sizes.

[0040] When the sole needs to be positioned, the sole that needs to be polished and trimmed is placed on the lower mold 11. When the second electric push rod 24 is started, the second electric push rod 24 drives the lifting ring 14 to move downward, and the lifting ring 14 drives the rotating ring 15 to move downward. The dual-axis motor 22 is started, and the dual-axis motor 22 drives the two rotating rods 21 to rotate. The rotating rod 21 drives the screw 18 to rotate through the transmission belt structure 23. The threads on the two screws 18 are in opposite directions.

After the first positioning, the two positioning rods 16 move back to their original positions, and the second motor 27 is started. The second motor 27 drives the gear 26 to rotate, the gear 26 drives the toothed belt 25 to rotate, and the toothed belt 25 drives the rotating ring 15 to rotate, so that the rotating ring 15 rotates 90 degrees. At this time, the sole is positioned for the second time by the movement of the positioning rods 16.
