Alternated plate feeding device

Abstract

The invention discloses an alternated plate feeding device, which comprises a conveyor belt, at least two plate clamping mechanisms and a slide rail, wherein the conveyor belt comprises a plurality of working sections arranged in parallel, and at least two of all the working sections have opposite conveying directions; the plate clamping mechanisms are fixedly connected to different working sections; and the slide rail is used for bearing reciprocating motion of the plate clamping mechanisms. The alternated plate feeding device does not slip during clamping; and the feeding distance can be conveniently calculated through the conveying distance of the conveyor belt, so that the feeding precision is greatly promoted. In the optimal technical scheme, a first plate clamping mechanism and a second plate clamping mechanism are adopted, so that idle travel is avoided in the feeding process, uninterrupted feeding is realized, and the feeding efficiency is greatly improved; and only one clamping part is required in one feeding stroke, so that the surface of a material is scratched little. The device has the advantages of convenience in control, high feeding precision, little surface scratch, high feeding efficiency and the like.

Description

technical field [0001] The invention relates to the field of advertising marking equipment, in particular to a plate alternate feeding device used in a font bending machine. Background technique [0002] In the advertising sign industry, three-dimensional characters are widely used, and the metal three-dimensional characters are usually bent into the contour shape of the characters by using a bending machine. Due to the complex outline of the characters, in order to ensure the precise matching between the outline of the border and the panel, a high-precision and high-efficiency feeding device is required. [0003] At present, the commonly used feeding device mainly adopts two sets of rollers with a certain distance. The plates pass through the middle of the rollers, and the motor drives the rollers to rotate. The plates sandwiched between the rollers are driven forward by the rollers under the action of friction. Because the feeding device is simple in structure and easy to...

AI Technical Summary

Problems solved by technology

If rubber is attached to the surface of the roller, it can avoid scratches on the surface of the plate, but the elasticity of the rubber will cause the diameter of the roller to be inconsistent when rotating, which will directly lead to uncontrollable precision and poor consistency of processing dimensions, and there are technical problems

[0007] The feeding method using a two-dimensional motion platform is more suitable for those equipments that require large-area plates as processing objects such as laser cutting and flat plate engraving of large plates. This feeding method is not suitable for continuous feeding of narrow belt plates. Therefore, There is currently no application in the field of font bending machines
