Abstract
Description
Technical Field
[0001] This utility model relates to a chain lubricant application device. Background Technology
[0002] Chains are important components of mechanical transmission, with long transmission distances and good adaptability. However, in order to maintain their service life and reduce noise, chains need to be lubricated regularly.
[0003] Current technologies typically involve manual, periodic application of oil using a grease gun, which is time-consuming, labor-intensive, and does not meet modern management standards. Other methods involve brushing, but these can result in wear or breakage of the brush, allowing oil to enter the chain and causing debris or uneven application. Drip lubrication, on the other hand, can cause liquid splashing, requiring space above the chain for the dripping liquid, which increases its volume.
[0004] Existing lubrication devices are larger and more expensive, and different chains require different customized oiling blocks.
[0005] Therefore, this utility model mainly solves the problems of the current oil brushes not being precise enough when applying lubricant to the chain, splashing oil droplets that may bounce everywhere and pollute the environment, the inability to accurately position the brush, the easy shedding of brush bristles, the inability to remove dried dirt, and the increase of chain load and wear. Utility Model Content

This invention primarily addresses the shortcomings of current oil brushes for applying lubricant to chains, such as insufficient precision, splashed oil droplets that pollute the environment, inaccurate brush positioning, brush shedding, and failure to remove dried dirt, all of which increase chain load and wear.
[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0008] To achieve precise lifting of the chain, a chain lubricant application device includes a carrier; a mounting bracket is provided on the carrier.

[0011] Channel grooves are provided on the lower surface of chain guide rail A and the upper surface of chain guide rail B respectively;
[0012] A gap is provided between the lower surface of chain guide A and the upper surface of chain guide B.
[0013] As a further improvement to the above technical solution:
[0014] To achieve height adjustment, chain guide rails A and B are respectively connected to the mounting bracket via corresponding adjusting screws.
[0015] To achieve chain control and precise lubrication, sensors and / or oil inlets are installed on chain guide rail A and / or chain guide rail B.
[0016] To facilitate the passage of the chain and facilitate the cleaning of oil stains, the oil inlet corresponds to the channel groove of the chain guide rail A.
[0017] To catch any spilled oil or grease, an oil collection box is installed below the chain guide rail B.
[0018] To enable monitoring of the chain's condition, sensors are positioned between the channel channels on both sides.
[0019] The sensor is electrically connected to the PLC;
[0020] To achieve unidirectional oil supply, the oil inlet is connected to the corresponding outlet check valve of the distributor.
[0021] To achieve system lubrication, the chain lubricant application device also includes a grease tank, a pump body connected to the grease tank, and a motor unit connected to the pump body.
[0022] To achieve electrical control, the grease tank is electrically connected to a pressure relay, and the pressure relay is electrically connected to a PLC.
[0023] The PLC is electrically connected to the motor unit and the proximity switch respectively;
[0024] The distributor has a proximity switch;
[0025] The proximity switch controls the frequency of operation of the monitoring distributor.
