Structure-improved connection rod bearing lubricating mechanism of needle machine

Abstract

The invention relates to a structure-improved connection rod bearing lubricating mechanism of a needle machine and belongs to the technical field of non-woven machines. The needle machine comprises a spindle with an eccentric cam and a connection rod arranged on the spindle. The connection rod bearing lubricating mechanism comprises a first oil pipe connector seat, a second oil pipe connector seat, a third oil duct, an oil splashing device and an oil collection tank. The first oil pipe connector seat is provided with a first oil inlet connector and a first oil outlet connector, the second oil pipe connector seat is provided with a second oil inlet connector and a second oil duct, the third oil duct is arranged on a connection rod bearing cover, one end of the third oil duct forms an oil hole, and the other end of the third oil duct forms an oil drainage cavity. The oil drainage cavity is communicated with a bearing oil cavity which is located between a connection rod bearing and the connection rod bearing cover and communicated with an oil leakage cavity, and the oil leakage cavity is located between a spindle sealing cover and the connection rod bearing cover and communicated with an oil leakage duct. The oil splashing device comprises a pair of oil splashing supporting feet and a pair of oil splashing caps, and the oil collection tank is fixed with a frame of the needle machine. The structure-improved connection rod bearing lubricating mechanism of the needle machine has the advantages of reducing operation strength, improving working efficiency, ensuring operation efficiency of the needle machine, having good lubricating oil supplementary effect and guaranteeing service life of the connection bearing.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a lubricating mechanism for a connecting rod bearing of an acupuncture machine with improved structure. Background technique [0002] As known in the industry, the acupuncture machine has a main shaft that is rotatably supported on the walls of the corresponding two sides of the main shaft box and one end is connected to the power transmission mechanism. An eccentric wheel (also called an eccentric cam) is arranged on the main shaft. , the connecting rod is sleeved on the eccentric wheel through the bearing (this bearing is customarily called the connecting rod bearing), and the left and right bearing caps connected with the bearing are respectively arranged on the left and right sides of the bearing. When the power transmission mechanism works, it drives the main shaft to rotate, thereby driving the connecting rod to move up and down, and the up and down ...

Problems solved by technology

[0004] The higher the speed of needling machine, the higher the needling speed, the greater the amount of non-woven products produced per unit time. Currently, the needling speed is 1000n / min The above needle looms are not uncommon, which is undoubtedly good news for manufacturers of non-woven products, but the lubrication effect of the connecting rod bearings must be in good condition during the working process of the needle looms, otherwise the connecting rod bearings are prone to heat. And bloating, resulting in downtime, this is a technical issue that manufacturers who use needle looms to produce non-woven products are concerned about.

[0005] At present, before this patent application is filed, manufacturers of acupuncture machines can only supplement the connecting rod bearings with regular or irregular maintenance and in the shutdown state. Lubricating oil, this method has the following shortcomings: First, when the connecting rod bearing is supplemented with lubricating oil, it is necessary for the equipment maintenance personnel to remove the above-mentioned left bearing cap and right bearing cap, and after the connecting rod bearing is replenished with oil, The left and right bearing caps are returned, so the maintenance personnel's work intensity is high and the efficiency is low; secondly, because the oil replenishment maintenance of the connecting rod bearing is carried out when the needle loom is stopped, the operation of the needle loom is affected efficiency; third, if the connecting rod bearing is neglected to replenish oil in time, once the bearing is damaged, it will take a long time to replace the bearing and the amount of work will be large, which will affect the production progress of non-woven products; fourth, because it is artificial Add lubricating oil to the connecting rod bearings, so the maintenance effect will be different according to the responsibility and experience of the maintenance personnel (or mechanics).

[0006] In view of the above-mentioned prior art, the applicant has done a deep and extensive literature search, but none of them have been found in the Chinese and foreign patents and non-patent literatures that have been disclosed so far. All have the enlightenment that can overcome above-mentioned technical problem
