Improved elastic piece feeding and cutting device

Abstract

The invention provides an improved elastic piece feeding and cutting device comprising a supporting base, a rear sliding block arranged on the supporting base in a sliding mode, a front stop block fixing base fixedly arranged in front of the rear sliding block, a first compressed spring arranged between the rear sliding block and the front stop block fixing base, an inclined block arranged above the rear sliding block and a lifting mechanism for driving the inclined block to ascend and descend so as to drive the rear sliding block to push elastic pieces. A pushing claw is arranged on the rear sliding block, a second compressed spring is arranged below the pushing claw, and when the elastic pieces are pushed, the pushing claw bounces upwards under the elastic force action of the second compressed spring and is inserted into a gap between the two elastic pieces which are not cut off; and the front stop block fixing base is provided with a front stop block, a third compressed spring is arranged below the front stop block, and when the elastic pieces are pushed in place, the front stop block bounces upwards under the elastic force action of the third compressed spring and is inserted into the gap between the two elastic pieces which are not cut off. The improved elastic piece feeding and cutting device has the advantages that the situation that the elastic pieces fed forwards are taken away backwards together in the backward returning process of the rear sliding block can be effectively avoided, and then the accuracy of the positions of the elastic pieces can be ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of slider production equipment, in particular to an improved shrapnel feeding and cutting device. 【Background technique】 [0002] At present, the assembly of the slider is automatically assembled by the zipper assembly machine. The shrapnel is an important part of the slider; The shrapnel is transported to the riveting position for riveting. When the existing shrapnel cutting device is working, the rear slider pushes the shrapnel forward under the action of the shrapnel-feeding inclined block arranged on one side, and the return of the rear slider is pushed back by the compression spring arranged at the front end of the rear slider; but , the existing shrapnel cutting device has the following defects when in use: 1. The rear slider may take the shrapnel to be cut back together in the process of returning to its position backwards, which will cause the position of the shrapnel to be inaccurate and affect t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an improved shrapnel feeding and cutting device to solve the problem that the existing shrapnel cutting device is prone to misalignment in the position of sending shrapnel during use. It is accurate and affects the normal cutting of the shrapnel, which can ensure the accurate and uniform position of the shrapnel, so that the shrapnel cutter can effectively cut the shrapnel
