Background

A steep-angle conveyor of a feeding machine is equipment for conveying and lifting materials in a cut tobacco production line in the tobacco industry, mainly adopts a frame split side chain type chain for conveying, and is often matched with a metering pipe and an electronic belt scale for use so as to realize the purposes of conveying the materials at a constant flow rate and balancing production by a conveying system. In the actual production process, in order to ensure the continuity of the tobacco material conveying system, the conveying speed of the bottom belt of the storage mechanism is inconsistent with that of the conveying belt of the hoister, so that when the materials are pushed forwards, thicker tobacco materials are often stacked at the junction of the bottom belt and the hoister, and great determined load and uncertain load are caused to the conveying chain of the steep-angle conveyor. Secondly, the conveying chain works in a damp and hot environment for a long time, if the chain is lubricated badly, a roller of the conveying chain cannot normally roll on a chain support and a chain wheel, so that friction and abrasion are aggravated, the transmission efficiency is reduced, the transmission vibration noise is increased, the driving power consumption is increased, mechanical faults such as chain climbing, clamping stagnation, deviation and even breaking occur, and the service life is seriously reduced. In addition, the smokability of cigarette products is also considered, the equipment lubrication of the tobacco shred production line in the tobacco industry has strict requirements on lubricating oil, the lubricating oil (agent) is required to reach the food grade, and the lubricating operation process is proper, so that tobacco materials cannot be polluted and the like. Therefore, good and accurate chain lubrication is an important guarantee for guaranteeing the constant flow and stable output of the pollution-free tobacco materials of the conveying system.

At present, the problem of lubrication of a material conveying system chain of a steep-angle conveyor of a feeding machine in the domestic tobacco industry is always a difficult point of lubrication of equipment in a tobacco-making production line in the tobacco industry, and due to the fact that the smoking property and the pollution risk of lubrication to tobacco materials of cigarette products need to be considered, the chain is subjected to lubrication-free management or manual irregular lubrication operation for many years. The manual lubrication mode has the defects that the tobacco material is polluted by large-range non-precise injection lubrication, the injection amount cannot be controlled, the waste of lubricating oil (agent) is serious, the maintenance cost is increased, the labor operation intensity is high, the safety is poor, the lubrication is insufficient, the efficiency is low, the condition of adding leakage or adding more lubricating oil (agent) exists, the lubricating effect is difficult to guarantee, the chain abrasion and failure problems are still serious, and the ideal lubrication mode capable of meeting the chain lubrication requirement of the tobacco material conveying system is not realized.
