Feeding mechanism achieving continuous leather material guide and preventing material from being stuck

Abstract

The invention discloses a feeding mechanism achieving continuous leather material guide and preventing a material from being stuck. The feeding mechanism comprises a feeding guide mechanism and pressplate guide mechanisms. The press plate guide mechanisms are used for pressing the edges of the leather material to sharp teeth of conveying chains with the sharp teeth, and therefore the leather material can be dragged by the conveying chains with the sharp teeth to move after the sharp teeth of the conveying chains with the sharp teeth pierce the edges of the leather material. Each press plate guide mechanism comprises a lower guide plate and an upper guide plate. The lower guide plates and the upper guide plates are installed on a lifting driving mechanism, and therefore the lower guide plates and the upper guide plates can be driven by the lifting driving mechanism to ascend and descend, and the piercing depths of the sharp teeth of the conveying chains with the sharp teeth are adjusted. According to the feeding mechanism, the upper guide plates and the lower guide plates in the press plate guide mechanisms ascend and descend to adjust the depths of the sharp teeth, piercing the leather material, of the conveying chains with the sharp teeth, and therefore the pull force of the conveying chains with the sharp teeth and on the two sides to the leather material is adjusted, and the frequency of the phenomenon that the leather material swings leftwards and rightwards is reduced; and the press plate guide mechanisms are combined with a series of limiting devices on the feeding guide mechanism, the phenomenon that the leather material swings leftwards and rightwards and fluctuates is avoided, and therefore the material is prevented from being stuck.

Description

technical field [0001] The invention relates to a forming machine, in particular to a forming machine for continuous leather material transmission through tooth tip transmission chains. Background technique [0002] Patent document CN 106429207A discloses a bottom-hanging sheet material conveying mechanism with a canine conveying chain. What the board conveying mechanism conveys is continuous leather. The continuous leather is conveyed under the pull of a chain with teeth. Due to the lack of regularity of the leather itself and the different force exerted on the leather by the conveyor chain with sharp teeth on both sides, the continuous leather is prone to swing from side to side when pulled. If the continuous leather material swings too much from side to side, there will be a problem of material jam. The easiest way to avoid the left and right swing of the continuous leather is to limit the two sides of the leather. However, in the case of only relying on the limit on ...

Problems solved by technology

[0003] The problem to be solved by the present invention: due to the lack of regularity of the leather itself and the different stress on the leather by the transmission chain with sharp teeth on both sides, the continuous leather is prone to swing left and right when pulled and the leather is wrinkled. , resulting in the problem of leather material jam
