It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration. Example

[0027] See also Figures 1 to 3 The present embodiment provides a novel quick-release and quick-change device for a tab cutter, comprising a base 1, a first lifting cylinder 2, a second lifting cylinder 3 and a cutter assembly 4. The first lifting cylinder 2 and the second lifting cylinder 3 are fixedly arranged on the top of the base 1, and the cutter assembly 4 is detachably arranged in the base 1 and is located below the first lifting cylinder 2 and the second lifting cylinder 3.

[0028] Specifically, the cutter assembly 4 includes a connecting block 41, a spring 42, an upper cutter seat 43, a movable cutter 44, a tab pressing block 45, a fixed cutter 46, a dust suction block 47 and a fixed seat 48. The fixed seat 48 is detachably connected to the base 1 through a positioning groove 481 at the bottom. The base 1 is provided with a corresponding positioning block 11. The fixed seat 48 is fixed by a locking screw after positioning. The fixed cutter 46 is fixedly arranged on the fixed seat 48. The dust suction block 47 is arranged on one side of the fixed cutter 46. The movable cutter 44 is connected to the upper cutter seat 43. The movable part is arranged above the fixed cutter 46 and corresponds to the fixed cutter 46 up and down. A tab pressure block 45 is fixedly arranged at the bottom of the upper cutter seat 43. The tab pressure block 45 is located on one side of the movable cutter 44. The connecting block 41 is connected to the top of the upper cutter seat 43 through a spring 42. The connecting block 41 corresponds to the tab pressure block 45. The cylinder axis of the first lifting cylinder 2 is downward and detachably connected to the upper cutter seat 43 through a coupling 21. The cylinder axis of the second lifting cylinder 3 is downward and connected to a top block 31. The top block 31 corresponds to the connecting block 41.

[0029] During operation, the cylinder shaft of the second lifting cylinder 3 extends out to drive the top block 31 to move downward, prompting the pole lug pressing block 45 to press the pole lug, and then the cylinder shaft of the first lifting cylinder 2 extends out to drive the movable cutter 44 to move toward the fixed cutter 46 to cut off the pole lug, and the dust suction block 47 absorbs the dust. After cutting the pole lug, the cylinder shafts of the first lifting cylinder 2 and the second lifting cylinder 3 retract.

[0030] When the tab cutter needs to be replaced, it is only necessary to loosen the locking screw between the cutter assembly 4 and the base 1, the cutter assembly 4 can be disassembled, and then the cutter assembly 4 that meets the requirements is installed, and positioned through the positioning groove 481 at the bottom, ensuring that the position of the cutter assembly 4 remains unchanged each time it is installed, and then fixed with the locking screw, which saves the debugging time of the cutter assembly 4, and the disassembly and assembly are quick and convenient. Finally, the device can be directly assembled on the machine, which greatly reduces the downtime (can reduce the downtime by more than 50%), is simple to operate, and effectively improves the production efficiency.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
