Claims

[Scope of utility model registration request]

a frame; a feed slider supported on the top of the frame so as to be movable in the front-rear direction; a first block that is removably attached to the uppermost end of the feed slider and has a guide groove for guiding the material;
It is detachably attached to the uppermost end of the frame in front of the block, and has a guide groove that guides the material coaxially with the guide groove of the first block, and a guide hole is formed above the guide groove. a second block, a pusher that is slidably inserted into the guide hole and is constantly biased forward by a spring;
a cutting blade that is supported by the block so as to be able to rise and fall, and when raised, cuts a part of the material protruding forward from the guide groove of the second block with a cutting blade provided at the upper end and lifts it up to just before the guide hole;
A fixed gripper is supported by the frame so that it can approach and separate from the guide groove of the second block, and presses and clamps the material against the guide groove when it approaches the guide groove, and a feed slider is supported so that it can approach and separate from the guide groove of the first block. A movable gripper that is supported and presses and clamps the material against the guide groove when it approaches the guide groove, a rotating shaft provided in the frame, and feeding, gripping, cutting, and ejecting grippers attached to the rotating shaft. a cam, a feed force transmission mechanism that is interposed between the feed cam and the feed slider and moves the feed slider by a predetermined feed amount in the front and back direction based on rotation of the feed cam, and is fixed to the gripping cam; A gripping force transmission mechanism is interposed between the movable gripper and causes the fixed and movable gripper to alternately approach and separate from the guide groove based on the rotation of the gripping cam, and the gripping force transmission mechanism is interposed between the cutting cam and the cutting blade. a cutting force transmission mechanism that raises and lowers the cutting blade based on the rotation of the cutting cam; and a cutting force transmission mechanism that is interposed between the ejection cam and the pusher, and that moves the pusher against the spring based on the rotation of the ejection cam; A material feeding device characterized by comprising a moving force transmission mechanism for moving the material backward.
