[0033] The front side of the cutter mechanism 16 can be further provided with a guide groove for centrally guiding the cut material to a storage place.

[0034] The specific working principle of the utility model is as follows:

[0035] Firstly, the material belt 4 is sent into the material belt guide groove 3 along the guide plate 15, at this time, the pulling pins 10 are lifted, and the material belt positioning holes 11 of the material belt 4 are aligned with the pulling pins 10.

[0036] The device of the utility model is started, and the material pulling pin 10 is moved downward under the action of the material pulling up-down air cylinder 8 and passes through the material belt positioning hole 11 to realize the clamping of the material belt 4.

[0037] When the sliding block 7 slides to the end of the slide rail 6, the material pulling front-rear air cylinder 8-1 stops pushing at this time, and the material pulling pin 10 also moves to the farthest end in the material pulling groove 9. The positioning device 12 is started, the positioning air cylinder 13 drives the positioning pin 14 to move downward, the positioning pin 14 extends into the material belt positioning hole 11 after passing through the positioning groove 14-1 to form the limiting and positioning.

[0038] The material pulling up-down air cylinder 8 drives the material pulling pin 10 to lift up, and the material pulling pin 10 is pulled out of the material belt positioning hole 11 to release the clamping of the material pulling pin 10 on the material belt 4, the material pulling front-rear air cylinder 8-1 drives the sliding block 7 to retreat along the slide rail 6, realizes the overall reset of the material pulling device 5, and completes the feeding action of the material belt 4.

[0039] The material belt 4 is stretched out of the fixed base 1 and extends into the lower part of the upper cutter 17 under the feeding action, the cutter power assembly 16-1 drives the lower cutter 18 to move upward, and the cutter heads of the upper cutter 17 and the lower cutter 18 are matched with each other to realize the cutting of the material belt 4 extending into the lower part of the upper cutter 17.

[0040] After cutting, the cutter power assembly 16-1 drives the lower cutter 18 to retreat, at this time, the material pulling up-down air cylinder 8 synchronously drives the material pulling pin 10 to move downward and extend into the material belt positioning hole 11 to realize the limiting of the material belt 4, and then the positioning air cylinder 13 drives the positioning pin 14 to ascend to realize the release of the positioning and limiting of the material belt 4.

[0041] At this time, the cutting operation is completed, and the subsequent steps are repeated to realize the continuous automatic operation.

[0042] The material belt 4 after cutting can fall into the storage place through the guide groove.

[0043] The above merely describes the specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and novel concept of the utility model within the technical range disclosed by the utility model can make equivalent replacement or change, which should be covered in the protection scope of the utility model.
