Automatic feeding device for buffer blocks

Abstract

The invention provides an automatic feeding device for buffer blocks. The automatic feeding device is suitable for stripping a plurality of buffer blocks arranged on a release paper material strip and realizing automatic feeding of the buffer blocks. The automatic feeding device comprises a rack, a buffer block feeding mechanism, a material strip recycling mechanism and a separation mechanism, wherein the buffer block feeding mechanism, the material strip recycling mechanism and the separation mechanism are respectively arranged on the rack; the release paper material strip extending from the buffer block feeding mechanism is recycled by the material strip recycling mechanism after passing through the separation mechanism; the separation mechanism comprises a separation block, and a material strip feeding guide surface and a material strip recycling guide surface are respectively arranged on the front side and the rear side; the front ends of the material strip feeding guide surface and the material strip recycling guide surface are intersecting to form an acute angle; the separation block can do reciprocating motion relatively to the rack along the arrangement direction of the material strip feeding guide surface. As the separation block can do reciprocating motion, in the process of separating from release paper, the buffer blocks can be subjected to the absorption of an external buffer block absorbing head and the stripping effect of acute angle end faces at the same time; the adhesive property of the buffer blocks and the release paper is overcome by depending on combination of the two effects, and therefore the buffer block with small size can also be separated from the release paper successfully.

Description

technical field [0001] The invention relates to a feeding device, in particular to an automatic feeding device for buffer blocks. Background technique [0002] For extremely small buffer blocks, several buffer blocks are usually arranged in batches on the release paper material tape, and the material is supplied in the form of a tape reel. Usually the material set on the release paper material belt, by passing the release paper material belt through the acute-angle end surface of the release block, relying on the release paper material belt due to the deformation of the acute-angle end surface to generate a peeling force between the material and the material. But for the buffer block with extremely small size, the peeling force generated between the buffer block and the release paper tape by the acute angle end face is not enough to overcome the bonding force between the buffer block and the release paper, and the buffer block is likely to be attached to the release paper. ...

But for the buffer block with extremely small size, the peeling force generated between the buffer block and the release paper tape by the acute angle end face is not enough to overcome the bonding force between the buffer block and the release paper, and the buffer block is likely to be attached to the release paper. The pattern paper strip and pass through the sharp-angled end face of the separation block, causing the separation pattern paper to fail
