Description

Calender capable of automatically injecting oil and calender oil injection device

Technical Field

The utility model relates to glass production equipment, in particular to a calender capable of automatically injecting oil and an oil injection device.

Background

The structure of the existing calender for producing photovoltaic glass mainly comprises an upper calender roll, an upper calender roll supporting seat, a lower calender roll and a lower calender roll supporting seat. Usually, the shaft heads at both ends of the upper and lower calender rolls are fixed in the bearing seats of the upper and lower main rolls by rolling bearings or DU bearings. The glass calender generally runs continuously on line for 24 hours, and the running duration can exceed one year at most, so the lubrication of the upper calender roll, the lower calender roll and the carrier roller which run continuously in the calender is very important. In order to ensure that the rolling bearing or the DU bearing is not damaged under the temperature condition of about 100 ℃, lubricating oil needs to be supplemented into the bearing seat at certain intervals. At present, each glass factory finishes the work of filling lubricating oil into a bearing seat of a calendering roller by manpower, and the oil filling work is realized by using a manual oil gun by staff. Because the calender roll group of calender generally includes two main calendering rollers and four attaches the roller, need to two bearing position oiling of both sides, especially two main roller bearing frame oiling spaces are narrow, and the temperature is high, and the difficulty is big, and this just must lead to the workman to expose in the heat radiation of high temperature glass area and the air convection of high temperature for a long time, even if wear the protective clothing, also the condition of heatstroke, dehydration or burn scald appears very easily.

The manual grease gun oiling mode has the following defects that firstly, the physical labor intensity of workers is high in the high-temperature environment of the site, the heatstroke phenomenon is easy to occur, meanwhile, the workers are easy to touch equipment with the high temperature of the site in the grease injection process, and the safety accidents that the workers are scalded and the like occur. Secondly, staff can't accurate control oiling volume at the oiling in-process, can only rely on the visual observation usually, wait the visual observation to see that oil is along the bearing bush lid outside after overflowing, just stop refueling. This results in a serious waste of lubricating oil. Leading to an increase in production costs. Thirdly, the overflowed lubricating oil or lubricating grease flows onto the ground rail without stopping, the more the lubricating oil or lubricating grease is accumulated, the more the lubricating oil or lubricating grease is, the more inconvenience is brought to the operation of the calender in and out, and meanwhile, the labor is required to clean the part of waste grease. Fourth, waste oils and fats also pose environmental hazards, requiring additional costs to dispose of this portion of hazardous waste. Fifthly, unstable and inaccurate oil injection frequency also brings non-optimal lubrication effect to the operation of the bearing, and increases the failure rate of equipment.

Through search, Chinese patent literature discloses an automatic lubricating mechanism of a glass calender (patent number ZL 201820482522.3; grant publication number CN 208058381U). The automatic lubricating mechanism of the glass calender comprises an oil tank, an oil pump and a plurality of oil outlet pipes, and the oil valve is controlled by a controller to realize the multipoint lubricating function of the glass calender. Firstly, when lubricating oil is added into an oil tank, the oil tank is in an exposed state, suspended particles in air are easy to mix in, and the corrosive suspended particles enter a bearing to cause bearing abrasion; secondly, the oil pump of the lubricating mechanism can only deliver lubricating oil, and in the actual glass production, the bearing of the glass calender needs to be lubricated by lubricating grease with high viscosity.
