Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubrication technology for assembly machines, and in particular to a lubrication device for the washboard support mechanism of the YJ27 assembly machine. Background Technology
[0002] The cigarette-jointing machine's folding board is a component used for joining cigarettes. Through its interaction with the joining rollers, it uses an adhesive (such as white glue) to bond the cigarette without a filter tip, the filter itself, and the tipping paper together. The folding board is a crucial part of the joining machine's process of forming filter-tipped cigarettes, ensuring that the glued tipping paper is smoothly wrapped around the cigarette and filter. The quality of the cigarette joining is primarily determined by the rolling action between the folding board and the joining rollers. The folding board has a direct impact on the quality of the cigarette joining.
[0003] During cigarette production, the cigarette undergoes a series of processing steps before reaching the splicing point. At this stage, a splicing wheel rolls the cigarette on a splicing board, while heating elements on the board heat the adhesive, softening it and enabling it to bond. Through the rolling of the splicing wheel and the heating of the board, the cigarette, filter, and tipping paper are firmly bonded together to form a complete cigarette.
[0004] During the production process of the cigarette rolling and splicing unit, deviations in the position of the rubbing plate cause quality defects in the cigarette tipping paper after wrapping and splicing. The rubbing plate is controlled by a four-bar linkage mechanism for raising and lowering. The rubbing plate should move slowly and smoothly into and out of the working position. Due to the harsh operating conditions of the cigarette rolling machine, including high dust levels, significant vibration, and the influence of moisture in the air, the bushings of the levers and arms in the four-bar linkage mechanism, as well as their mating shafts, are prone to rust. This increases the resistance at the contact surfaces, causing minor issues like jamming or, in severe cases, complete malfunction of the linkage mechanism, preventing normal operation. The rubbing plate itself lacks a lubrication system and cannot meet the harsh requirements of the equipment's operation. Despite repeated repairs, adjustments, and parts replacements, the problem persists, resulting in ineffective quality control of cigarette products, uncontrolled scrap rates, and a significant increase in production costs.

[0023] refer to Figure 1The lubrication device for the washboard support mechanism of the YJ27 assembly machine includes: a lever arm 1 and a lever 2. Both lever arm 1 and lever 2 are U-shaped rods, and a fixing block is fixedly connected at an angle to the outer side of the middle of lever arm 1 away from both ends. The side walls of lever arm 1 and lever 2 are respectively fixedly connected to the washboard. Lubrication components are respectively installed in the middle of lever arm 1 and lever 2. The lubrication components include a fixing shaft 3, a fixing screw 4, and a fixing washer 5. The outer wall of the fixing shaft 3 is provided with an oil-collecting groove group, which includes an annular oil-collecting groove and multiple linear oil-collecting grooves. Multiple linear oil-bearing grooves are radially spaced equidistantly along the circumference of the outer wall of the fixed shaft 3 or lever 2, and are connected to an annular oil-bearing groove. In this embodiment, the annular oil-bearing groove has a width of 6 mm and a depth of 1 mm. There are 6 linear oil-bearing grooves, each with a width of 1 mm and a depth of 1 mm. The fixing screw 4 is an M8 stainless steel socket head cap screw. The fixing washer 5 is a 5 mm thick annular stainless steel washer. A through hole is radially provided on the fixed shaft 3. After passing through the middle of the lever arm 1 / lever 2, the fixed shaft 3 is threadedly connected to the fixing screw 4 through the through hole. A fixing washer 5 is sleeved around the fixing screw 4 and is located between the fixing screw 4 and the lever arm 1 / lever 2. The end of the fixed shaft 3 away from the fixing screw 4 is fixedly connected to the MAX part of the cigarette machine. A grease filling assembly is symmetrically provided on the outer side of the lever arm 1 and the lever 2. The grease filling assembly includes a through threaded hole 8 and a grease nozzle 7. Both ends of the lever arm 1 and the lever 2 are provided with a drive device. The grease nozzle 7 is a combined pure copper copper elbow type grease nozzle 7, and the included angle between the grease nozzle 7 and the axial connection of the fixed shaft 3 is 45°. The through threaded hole 8 is opened on the outer side of the middle of the lever arm 1 / lever 2, and the oil receiving groove group and the threaded hole 8 after the fixed shaft 3 passes through the middle of the lever arm 1 / lever 2 are threadedly connected to the grease nozzle 7. A grease gun for supplying oil into the lever arm 1 / lever 2 is connected to the grease nozzle 7. Both ends of the lever arm 1 and the lever 2 are equipped with driving devices. The driving devices include the lever 2 shaft and a cylinder. The lever 2 shaft passes through the end of the lever arm 1 / lever 2, and the end of the lever 2 shaft located outside the lever arm 1 / lever 2 is rotatably connected to the piston rod of the cylinder.
[0024] The lever 1, lever 2, two lubrication components, and two oiling components form a four-bar linkage. One end of the fixed shaft 3 of the four-bar linkage is clamped to the cigarette machine with screws and connected to the cylinder piston rod via a spherical bearing. This allows the rubbing plate to rise or fall, adjusting the gap between the rubbing plate and the rubbing drum, i.e., the compression of the filter cigarette by the rubbing plate. The lever 1 and lever 2 of the four-bar linkage of the rubbing plate mechanism are clearance-fitted with the two fixed shafts 3, ensuring that the lever 1 and lever 2 move relative to each other around the two fixed shafts 3 under the action of the cylinder. This allows the rubbing plate connected to the four-bar linkage to rise or fall. The rubbing plate should rise or fall slowly and in one step when entering or leaving the working position. The clearance fit between the fixed shaft 3 and the lever 1 and lever 2 ensures that grease is always present in the gap. After the lever 1 and lever 2 of the oiling cup are installed on the corresponding shafts, an appropriate amount of grease is applied to the two oil nozzles 7 using a special grease gun, and the grease can be squeezed out from the gap. The grease is squeezed out from the gap and the six oil grooves of the two fixed shafts 3 are fully filled with grease, so as to achieve constant lubrication, effectively prevent rust, and ensure that the four-bar linkage of the washboard can still enter or leave the working position normally under extremely low air pressure, ultimately achieving the purpose of lubricating the washboard support mechanism.
