[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Please also read Figures 1 to 6 Now, the quick-release tightening device for the toe shaping machine provided in the embodiment of the present application is described. The quick-release tightening device 10 for the toe shaping machine comprises: a tightening device and a locking assembly.

[0033] The quick-release tightening device 10 includes a left clamping plate 11, a right clamping plate 12 and a tightening clamp 13; the left clamping plate 11 and the right clamping plate 12 are pivotally connected to each other, and the tightening clamp 13 is installed at the bottom of the left clamping plate 11 and the right clamping plate 12, and the position of the tightening clamp 13 can be adjusted by rotating the left clamping plate 11 and the right clamping plate 12 relative to each other; the locking assembly includes a fixed plate 14, a movable plate 15 movably installed on the fixed plate 14, a first cylinder 16 fixedly installed on the movable plate 15 and a locking plate 17 of a telescopic rod fixedly installed on the first cylinder 16; the movable plate 15 and the locking plate 17 are arranged at a vertical distance and form a clamping space 18, and when the tightening device is inserted into the clamping space 18, the locking plate 17 can move upward relative to the movable plate 15 to clamp the tightening device.

[0034] Specifically, during operation, the tightening device is inserted into the clamping space 18, and then the locking plate 17 is driven upward by the first cylinder 16, and the tightening device can be clamped to lock it; when replacing the tightening device, it is only necessary to drive the locking plate 17 downward by the first cylinder 16 to cancel the clamping force on the tightening device, and then the tightening clamp 13 can be taken out to replace the tightening device with a tightening clamp of a different type; compared with the prior art, there is no need to use screws to fasten the tightening device, which improves the convenience of replacing the tightening clamp, shortens the replacement time, and thus improves production efficiency.

[0035] In some embodiments of the present application, a first positioning column 111 is installed at the center point where the left clamping plate 11 and the right clamping plate 12 rotate relative to each other, and the locking plate 17 is provided with a first positioning notch 171; when the tightening device is inserted into the clamping space 18, the first positioning column 111 is inserted into the first positioning notch 171. A second positioning column 112 is installed on the left clamping plate 11 and the right clamping plate 12 respectively, and the locking plate 17 is provided with a second positioning notch 172; when the tightening device is inserted into the clamping space 18, the second positioning column 112 is inserted into the second positioning notch 172.

[0036] It should be noted here that the first positioning column 111 is arranged at the bottom rear end of the left splint 11 and the right splint 12. The left splint 11 and the right splint 12 can be rotated relative to each other to expand or tighten, thereby changing the shape and size of the tightening clamp and adjusting the size of different types of shoe toes to accommodate shoe toes of different sizes.

[0037] During operation, the left clamping plate 11 and the right clamping plate 12 are inserted into the clamping space 18. At this time, ensure that the first positioning column 111 is inserted into the first positioning notch 171, and the second positioning column 112 is inserted into the second positioning notch 172 to ensure that the tightening device is located in the correct position after installation. There is no need to readjust the front-to-back and left-to-right positions of the entire tightening clamp, thereby improving the convenience and accuracy of replacing the tightening device.

[0038] In more detail, in order to improve the accuracy of the left clamping plate 11 and the right clamping plate 12 being installed into the clamping space 18, guide slopes 173 are set on the two opposite sides of the front end of the locking plate. When the left clamping plate 11 and the right clamping plate 12 are installed into the clamping space 18, the second positioning column 112 can be inserted into the clamping space 18 through the guide slope 173, and the first positioning column 111 is inserted into the first positioning notch 171, and the second positioning column 112 is inserted into the second positioning notch 172.

When the shape and size of the tightening clamp need to be adjusted, it can be adjusted by rotating the first stop screw 145; the first tension spring 113 mainly provides a pulling force for the left clamp 11 and the right clamp 12 to open outward, and the second tension spring 131 provides a pulling force for the front end of the tightening clamp to ensure that the tightening clamp can follow the adjustment when the first stop screw 145 is adjusted.

[0040] In more detail, the fixed plate 14 is provided with a first notch 141, and the left and right sides of the first notch 141 are provided with first sliding grooves 142, and the left and right ends of the movable plate 15 are movably installed corresponding to the first sliding grooves 142 on both sides. The front end of the fixed plate 14 is screwed with a first positioning screw 143, and the first positioning screw 143 can abut against the front end of the movable plate 15; the rear end of the fixed plate 14 is screwed with a second positioning screw 144, and the second positioning screw 144 can abut against the rear end of the movable plate 15. With such a structure, the front and rear positions of the movable plate 15 can be adjusted by rotating the positions of the first positioning screw 143 and the second positioning screw 144.

[0041] In other embodiments of the present application, a middle plate fixture 19 and a cold mold 110 are also included, and the tightening device, the middle plate fixture 19 and the cold mold 110 are arranged in sequence from top to bottom. Specifically, the cold mold 110 is fixedly installed on a workbench (not shown in the figure), and the workbench is movably installed with a first guide rod 130, and the first guide rod 130 is movably sleeved with a second guide rod 140, and a driving device 150 is installed at the bottom of the second guide rod 140, and the driving device 150 is preferably a cylinder, and the driving device 150 is fixedly installed on the workbench; the middle plate fixture 19 is installed on the first guide rod 130, and the tightening device is installed on the second guide rod 140.

[0042] During operation, the second guide rod 140 moves downward, driving the tightening device to move downward, so that the tightening clamp is against the upper surface of the middle plate clamp 19 to clamp the leather, and then the second guide rod 140 continues to move downward to drive the tightening clamp and the middle plate clamp 19 to move downward synchronously, pressing the leather against the cold mold 110 and continuing for 30S-180S to shape the leather into the required shape of the toe.

[0043] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way.
