Abstract

The utility model discloses a tooth tip chain transmission mechanism with a pressing wheel. The chain bracket of the tooth tip chain transmission mechanism is provided with a material pressing wheel mechanism. The pressing wheel mechanism comprises a pressing frame and a pressing wheel arranged on the pressing frame. The material pressing frame is arranged on the chain bracket through a spring guide post mechanism. The surface of the pressing wheel is provided with a tooth tip groove for the tooth tip chain sharp teeth to pass through. The surface of the material pressing wheel is made of elastic materials. According to the utility model, the clamping is carried out on the sheet conveyed on the tooth tip chain through the pressing wheel, so that the falling off caused by the gravity pulling of the sheet is avoided, and when the pressing wheel clamps the sheet, the friction force caused by clamping can be reduced through the friction rolling of the pressing wheel through the spring and the elastic material of the pressing wheel.

Description

Toothed tip chain transmission mechanism with pressing wheel Technical Field The utility model relates to a conveying mechanism with a sharp tooth conveying chain. Background The tooth tip chain, namely, the conveying chain with the sharp teeth is commonly used on leather forming equipment, and leather is conveyed by carrying leather after the sharp teeth on the conveying chain pierce the edge of the leather. There are two modes of conveying the leather through the toothed chain, namely, a mode that the conveying chain supports the leather below the leather, as disclosed in patent document CN104828472A, and a conveying mode that the leather is hung below the conveying chain, as disclosed in patent document CN 106429207A. In the manner in which the conveyor chain supports the skin underneath the skin, the conveyor chain tines face upward. When the sheet edge is conveyed after being pierced by the tooth tip chain sharp teeth, the sheet edge is easy to separate from the tooth tip chain sharp teeth due to the fact that the sheet dead weight generates pulling of the conveying chain. Disclosure of Invention The utility model aims to solve the problem that in a tooth tip chain conveying mechanism with upward tooth tips, sheets fall off during conveying. In order to solve the problems, the utility model adopts the following scheme: The tooth tip chain transmission mechanism with the material pressing wheels comprises a conveying frame and chain frames arranged on two sides of the conveying frame, wherein tooth tip chains are arranged on the chain frames, the chain frames comprise chain brackets used for supporting the tooth tip chains among chain wheels, the chain brackets are provided with material pressing wheel mechanisms, each material pressing wheel mechanism comprises a material pressing frame and a plurality of material pressing wheels arranged on the material pressing frame, the material pressing frames are arranged on the chain brackets and are parallel to the chain brackets, the material pressing wheels are arranged at intervals along the moving direction of the tooth tip chains, annular tooth tip grooves are formed in the wheel surfaces of the material pressing wheels along the circumferential direction, and tooth tips of the tooth tip chains on the chain brackets can be located in the tooth tip grooves of the material pressing wheels when the tooth tip chains move. Further, the interval between adjacent material pressing wheels on the material pressing frame is not more than 30cm. Further, the material pressing frame is arranged on the chain bracket through a spring guide post mechanism; the spring guide pillar mechanism comprises a mounting frame fixed with the chain bracket, a guide pillar and a spring, wherein the guide pillar is connected with the material pressing frame through the mounting frame, the guide pillar is vertically arranged and movably connected with the material pressing frame, so that the material pressing frame can be lifted under the limit and guide of the guide pillar, and the spring is vertically arranged and provides downward elastic pressure for the material pressing frame. Further, the pressing wheel surface is made of elastic materials. The clamping device has the technical effects that the clamping device clamps the sheet conveyed on the tooth tip chain through the pressing wheel, so that the falling of the sheet due to gravity pulling is avoided, and when the pressing wheel clamps the sheet, the friction force caused by clamping can be reduced through friction rolling of the pressing wheel through the spring and the elastic material of the pressing wheel.
