Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a lubrication mechanism for a chain conveyor. Background Technology

[0002] Chains are one of the mechanical transmission components. Their working principle involves using a hyperbolic arc chain to reduce friction between the chain and sprockets, thereby minimizing energy loss during power transmission and achieving high transmission efficiency. Because of their precise power transmission capabilities and numerous excellent characteristics such as stable transmission, constant speed, strong adaptability, insensitivity to size, and ease of maintenance, chains are widely used in various industries. Especially in today's highly automated production equipment, chains have become an indispensable transmission component in mechanical systems.

[0003] Currently, chain lubrication methods include brush lubrication, drip lubrication, oil bath or oil pan lubrication, and spray lubrication. Brush lubrication involves periodically applying oil to the inner and outer chain links on the slack side using a brush or oil can. The amount and frequency of oil application should be sufficient to prevent discoloration of the lubricating oil at the chain link joints. Drip lubrication uses an oil cup to drip oil between the two hinge plates. The amount and frequency of oil application should also be sufficient to prevent discoloration of the lubricating oil at the chain link hinges. It is essential to prevent the oil droplets from being blown off course by wind; if the oil droplet is in the center of the chain, it cannot effectively lubricate the contact area. The lubricating oil must be guided to the inner side of the pins and the surface of the roller side plates. Oil bath or oil pan lubrication involves passing the lower chain through an oil sump in the gearbox. The oil level should reach the pitch circle line of the lowest position of the chain. When using oil pan lubrication, the chain operates above the oil surface. The oil carried from the oil sump by the oil pan is often guided by an oil groove, allowing the oil to settle onto the chain. In this process, oil spraying lubrication involves supplying a continuous flow of oil to each drive chain. The oil should be applied to the inside of the chain links, precisely at the joints of the chain plates, and guided evenly along the chain width to the slack side of the chain.

[0004] However, existing lubrication devices or systems all suffer from the problem of continuous and excessive lubrication, resulting in resource waste. Utility Model Content

[0005] The purpose of this invention is to provide a lubrication mechanism for a chain conveyor in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A chain conveyor lubrication mechanism, comprising:

[0008] The support frame is positioned above the chain conveyor.

[0009] A lubricating oil dripping pipe is vertically installed at the rear of the lower part of the support, with the oil outlet of the lubricating oil dripping pipe facing the chain conveyor so that the oil dripping from the lubricating oil dripping pipe drips onto the chain of the chain conveyor.

[0010] A lubricating oil cylinder is installed on the upper part of the support. A connecting pipe is provided between the lubricating oil cylinder and the lubricating oil dripping pipe, so that the lubricating oil cylinder can provide lubricating oil to the lubricating oil dripping pipe through the connecting pipe.

[0011] A solenoid valve is installed on a connecting pipe to control the opening and closing of the connecting pipe.

[0012] As an improvement to the above technical solution, the solenoid valve is a liquid solenoid valve, which controls the liquid flowing through the connecting pipe to realize the intermittent entry of lubricating oil from the lubricating oil cylinder into the lubricating oil dripping pipe.

[0013] As an improvement to the above technical solution, an oil collection trough is provided below the chain conveyor; the position of the oil collection trough corresponds to the position of the lubricating oil dripping pipe, so as to collect any excess lubricating oil that may drip from the lubricating oil dripping pipe.

[0014] As an improvement to the above technical solution, the chain conveyor lubrication mechanism also includes a control mechanism. The control mechanism includes a tension sensor and a flexible pressure block located at the front of the support, a microcontroller located at the top of the support, and a solid-state relay. The tension sensor and solid-state relay are connected to the microcontroller, and the solenoid valve is connected to the solid-state relay.

[0015] The flexible pressure block is in flexible contact with the chain. The probe of the tension sensor is located between the flexible pressure block and the chain to measure the tension of the chain and upload the tension information to the microcontroller. The microcontroller controls the solid-state relay according to the tension and then controls the solenoid valve to open or close, thereby controlling the liquid flowing through the connecting pipe.

[0016] As an improvement to the above technical solution, the control mechanism also includes a servo motor fixed in the middle of the bracket and a steel brush connected to the servo motor. The servo motor is electrically connected to a single-chip microcomputer through a solid-state relay, and the steel brush flexibly contacts the chain to clean the chain.

[0017] As an improvement to the above technical solution, a sludge collection trough is provided below the chain conveyor, and the position of the sludge collection trough corresponds to the position of the steel brush.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1-2 As shown, this utility model provides a lubrication mechanism for a chain conveyor, which is set above the chain 1 and includes a support 2, a lubricating oil cylinder 3 and a control device 4 set above the support 2, a tension sensor 5 and a flexible pressure block 6 set at the front of the support 2, a steel brush 8 set at the middle of the support 2 and a lubricating oil dripping pipe 9 set at the rear of the support 2. A sludge collection groove 11 is set below the steel brush 8 and an oil collection groove 12 is set below the lubricating oil dripping pipe 9. The bottom of the lubricating oil cylinder 3 is connected to the lubricating oil dripping pipe 9 through a solenoid valve 10. The steel brush 8 is controlled by a servo motor 7 to clamp / release the chain 1. The control device 4 includes a microcontroller and a solid-state relay. The tension sensor 5 is connected to the input terminal of the microcontroller, and the output terminal of the microcontroller controls the switching of the solenoid valve 10 and the servo motor 7 through the solid-state relay.

[0026] When using this device, the probe wire 51 of the tension sensor 5 is placed between the flexible pressure block 6 and the chain 1. When the chain 1 is sufficiently clean, the value of the tension sensor 5 is relatively small. When there is a lot of oil on the surface of the chain 1, its surface viscosity increases, and the value measured by the tension sensor 5 increases. When the set threshold is reached, the microcontroller controls the servo motor 7 and the solenoid valve 10 to open and work, so as to clean and lubricate the chain 1. When the value measured by the tension sensor 5 decreases, the microcontroller controls the servo motor 7 and the solenoid valve 10 to stop the cleaning and lubrication of the chain through the solid-state relay.
