Description

Technical Field

[0001] This utility model belongs to the field of chain lubrication technology, and specifically relates to an automatic chain lubrication device. Background Technology

[0002] For enterprises producing mineral wool, the cotton collecting machine is an essential piece of equipment. To ensure the normal operation of the cotton collecting machine, the chain on the machine needs to be lubricated to ensure its stable operation. The existing chain lubrication device requires manual start and stop. When the cotton collecting machine stops, the chain lubrication device is still running. Especially when workers forget to turn off the chain lubrication device, it may cause a large amount of lubricating oil to leak out, which not only pollutes the working environment but also easily causes a fire. At the same time, the existing chain lubrication device lubricates the entire working surface of the chain when it is working, but the actual lubrication only needs to cover the chain plate. Lubricating the rollers in the middle of the chain can also easily cause lubricating oil to drip from the gaps between adjacent rollers, resulting in the waste of lubricating oil. Utility Model Content

[0003] This invention provides an automatic chain lubrication device to address the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic chain lubrication device includes an oil tank, with an oil spray pipe connected to the lower part of the oil tank. An electric valve is installed on the oil spray pipe, which supplies oil to a lubrication wheel. The lubrication wheel is mounted on a U-shaped frame and contacts the upper surface of the chain. The U-shaped frame is fixedly connected to one end of a support rod, and the other end of the support rod is rotatably mounted on a hinge lug. The hinge lug is fixedly welded to a mounting plate, which is bolted to a fixed bracket. A non-contact sensor is installed at the lower end of the fixed bracket, located above the chain, to detect whether the chain is running. The non-contact sensor is electrically connected to a controller to transmit a detection signal to the controller. The controller is also electrically connected to the electric valve to control the opening and closing of the electric valve based on the signal transmitted by the non-contact sensor.

[0006] Furthermore, the refueling wheel includes a first wheel body, on which an arc-shaped groove is formed on the circumferential surface. Brushes are fixedly arranged on both sides of the arc-shaped groove, and the brushes are arranged corresponding to the chain plates on both sides of the chain. A through hole is formed in the center of the first wheel body for the shaft to pass through. Grooves are formed at both ends of the through hole, and bearings are installed inside the grooves. A shaft is installed inside the two bearings. The shaft is fixedly connected to a U-shaped frame, and the oil spray pipe is located above the arc-shaped groove.

[0007] Furthermore, the refueling wheel includes a second wheel body. An oil inlet is formed in the center of one side of the second wheel body. An oil groove with a V-shaped cross-section is formed inside the second wheel body. A clearance groove is formed in the center of the circumferential surface of the second wheel body to prevent the second wheel body from contacting the roller in the middle of the chain, thus preventing damage to the chain. Multiple oil outlet holes are formed on both sides of the clearance groove, evenly distributed along the circumferential surface of the second wheel body. The oil outlet holes are connected to the oil groove and are fixedly installed within the oil outlet hole area on the circumferential surface of the second wheel body. The device has bristles. A first fixed shaft is provided on one side of the second wheel body. The first fixed shaft is threadedly connected to the oil inlet hole. The first fixed shaft has a hollow structure. The inner cavity of the first fixed shaft is connected to the oil inlet hole. The outer wall of the first fixed shaft is sealed to the oil inlet hole. A second fixed shaft is fixedly provided on the other side of the second wheel body. The first and second fixed shafts are rotatably connected to the two sides of the U-shaped frame. A rotary joint is rotatably connected to the outer end of the first fixed shaft. The other end of the rotary joint is connected to the oil spray pipe.

[0008] Furthermore, the non-contact sensor is a photoelectric sensor.

[0009] Furthermore, a liquid level sensor is installed inside the oil tank. The liquid level sensor is electrically connected to the controller, and the controller is also electrically connected to a buzzer for issuing an alarm when the liquid level reaches below a set value.

[0010] Furthermore, a variable frequency pump and an electronic pressure gauge are also installed on the oil spray pipe, and both the variable frequency pump and the electronic pressure gauge are electrically connected to the controller.

[0011] Furthermore, an elongated hole is provided on the fixed bracket, through which the bolt is installed to facilitate the adjustment of the mounting plate position, thereby enabling the adjustment of the refueling wheel position.

[0012] Furthermore, a tension spring is provided between the support rod and the fixed bracket.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention uses a non-contact sensor to detect whether the chain is running, and then controls the opening and closing of the electric valve through a controller, which can realize the synchronous start and stop of the cotton collecting machine and the lubrication device, and prevent the lubricating oil from leaking out because the worker forgets to turn off the lubrication device;

[0015] This utility model provides targeted lubricant application to the chain plates on both sides of the chain, which can accurately apply the lubricant to the chain plates, avoid lubricant waste, improve the cleanliness of the on-site working environment, and eliminate the fire hazard caused by lubricant dripping.
