[0002] The pressure roller is a component installed on the briquetting machine and cooperates with the forming mold on the briquetting machine to roll straw or solid waste into briquettes. It generally includes an eccentric shaft, an eccentric sleeve and a roller bearing. The roller bearing is installed between the eccentric shaft and the eccentric sleeve. In order to ensure its normal operation, lubricating oil is injected into the roller bearing. The existing lubrication structure generally sets an oil channel leading to the bearing on the eccentric shaft and the eccentric sleeve, and injects the lubricating oil through the oil channel. However, this lubrication structure has the following defects: (1) The lubricating oil enters the bearing as a fluid for lubrication, which is easy to cause large waste and increase production costs; (2) Some lubricating oils are easily deteriorated by heat and easily form lumps or produce oil stains after mixing with dust, which affects the lubrication effect. Therefore, the present application proposes an oil mist lubrication structure for a pressure roller to solve the above technical problems. Utility Model Content

[0014] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0015] like Figure 1The oil mist lubrication structure for a pressing roller provided in the present embodiment is shown, which is installed on a briquetting machine and cooperates with a forming mold on the briquetting machine to press straw or solid waste into briquettes; the lubrication structure comprises an eccentric sleeve 10, a pressing wheel 20, a roller bearing 30, an oil mist generator 31 and an atomizing nozzle 40, the internal cavity of the eccentric sleeve 10 is eccentrically arranged for inserting an eccentric shaft, the pressing wheel 20 is sleeved on the outside of the eccentric sleeve 10, and the roller bearing 30 is installed between the pressing wheel 20 and the eccentric sleeve 10; an L-shaped oil passage 101 is axially arranged in the side wall of the eccentric sleeve 10, the inlet of the L-shaped oil passage 101 is arranged at the top of the eccentric sleeve 10, and the outlet of the L-shaped oil passage 101 is arranged on the side wall of the eccentric sleeve 10, and the outlet is located above the roller bearing 30; the atomizing nozzle 40 is installed at the outlet of the L-shaped oil passage 101, and the oil mist generator 31 is connected to the inlet of the L-shaped oil passage 101 through a lubrication pipeline 50.

[0016] The eccentric sleeve 10 of this embodiment is sleeved on the eccentric shaft of the briquetting machine. In order to ensure the normal use of the eccentric sleeve 10, the roller bearing 30 and the pressing wheel 20, the roller bearing 30 needs to be lubricated. Specifically, a chamber for storing lubricating oil 100 is provided inside the oil mist generator 31. Compressed air is sucked into the oil mist generator 31 to generate negative pressure to suck the lubricating oil 100 out of the chamber and fully mix it with the compressed air to enter the lubrication pipeline 50, enter the L-shaped oil channel 101 through the lubrication pipeline 50, and is sprayed onto the roller bearing 30 in the form of oil mist through the atomizing nozzle 40 to lubricate and cool the roller bearing 30. This lubrication structure can save a lot of lubricating oil 100, so that the roller bearing 30 can be infiltrated and lubricated and can be cooled in time, so as to avoid the lubricating oil from agglomerating or generating oil scale when encountering heat and dust during the working process, thereby extending the service life of the bearing and reducing the production cost.

[0017] Furthermore, the present embodiment also includes a positioning sleeve 60, a sealing cover 70 and a skeleton oil seal 80.

[0018] Specifically, in this embodiment, positioning sleeves 60 and sealing covers 70 are installed at both ends and the inner side of the pressure wheel 20, and a skeleton oil seal 80 is installed between the positioning sleeve 60 and the sealing cover 70. This can not only prevent external dust from entering the internal roller bearing 30 and ensure the normal use of the roller bearing 30, but also prevent the internal lubricating oil 100 from leaking, save the use of the lubricating oil 100, and thus reduce the production cost.

[0019] Furthermore, in the present embodiment, a positioning bearing 90 is provided on the eccentric sleeve 10 between the atomizing nozzle 40 and the roller bearing 30, which can prevent the pressure of the pressure roller from acting on the skeleton oil seal 80 during operation, prevent the skeleton oil seal 80 from deforming, and reduce wear and tear. In addition, the oil mist passing through the atomizing nozzle 40 can be sprayed onto the positioning bearing 90 and drip onto the roller bearing 30 for lubrication and cooling.
