Description
Technical Field
The utility model relates to an extruder die head oil absorption cigarette is equipped, concretely relates to extension lithium ion battery diaphragm die lip life cycle's equipment belongs to extruder die head oil absorption cigarette and equips technical field.
Background
White oil is used as an essential raw material for a wet diaphragm, a large amount of oil smoke is generated during die head discharging after the white oil is melted and mixed at high temperature by an extruder, and the oil smoke is accumulated for a long time to cause the phenomenon that the die lip is easy to hang, so that the product quality is influenced, and the die lip needs to be cleaned by stopping the machine; the spreading surface of an oil fume exhaust device used by the existing die head is large, and the oil fume adsorption capacity is insufficient, so that on one hand, the service cycle of a die lip of a 9-micron product is about 7 days, the service cycle of a die lip of a 12-micron product is about 5 days, the machine halt is frequent, and the time utilization rate is low; on the other hand, the cleanliness of a casting workshop can not meet the requirement, and the problems of thin point defects and the like are easily caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an extension lithium ion battery diaphragm die lip life cycle's equipment has prolonged die lip life cycle, has improved cleanliness factor in the workshop moreover, and product white point class flaw occurrence reduces.
The utility model discloses a device for prolonging the service cycle of a lithium ion battery diaphragm die lip, which comprises a sheet extrusion die head; an oil smoke extractor is arranged at the upper part of the front side of the die head; the oil-spraying device also comprises an oil blower and an oil extractor; the oil blower is arranged at one end of the discharge side of the die head, and the oil absorber is arranged at the other end of the discharge side of the die head; the oil blower comprises a plurality of braided hoses; one end of the braided hose is connected to the main pipe; the main pipe is connected to the pressure fan, and the other end of the braided hose is connected with the middle pipe; an air blowing nozzle is fixed at the output end of the middle pipe; the oil extractor comprises a large-pipe-diameter pipe barrel; the pipe barrel is connected to the main pipe of the exhaust fan through the telescopic pipe.
When the smoke exhaust pipe is used, the blowing nozzle is used for blowing air, the high-specific gravity white fog is blown to the pipe barrel by utilizing the high-linearity air, the pipe barrel is used as an air suction pipe, the air suction surface is small, the high-specific gravity white fog on the periphery can be efficiently and quickly sucked away through the exhaust fan, meanwhile, the smoke exhaust ventilator is reserved, the large spreading surface of the smoke exhaust ventilator is utilized, the floating smoke with light specific gravity on the periphery is sucked away by adopting a large area, and therefore the position of the die head can be efficiently sucked away from the white smoke.
Further, the intermediate pipe is fixed body or universal shaping pipe, when adopting fixed body, hoists the blowing nozzle interval through the gallows, and the face of blowing of adjacent blowing nozzle covers each other, when adopting universal shaping pipe, can be according to on-the-spot smoke exhaust effect adjustment blowing nozzle position, and the blowing nozzle needs to go out the membrane position towards the die head.
Furthermore, the air blowing nozzle and the pipe barrel are both arranged below the oil fume extractor; the middle pipe and the pipe barrel are fixed on a die set of the sheet extrusion die head through a hanging bracket, the middle pipe and the pipe barrel are matched to firstly complete the smoke pumping with higher bottom, and the floating smoke is secondarily captured through an oil smoke extractor with large coverage area.
Compared with the prior art, the device for prolonging the service cycle of the lithium ion battery diaphragm die lip of the utility model is provided with the air blowing pipe and the air suction pipe, wherein the air blowing head blows oil smoke to one side of the die head under high pressure, and the air suction pipe sucks the oil smoke away, thereby reducing the oil smoke content in a workshop; the equipment not only prolongs the service cycle of the die lip (the service cycle of the die lip of a 9-micron product is more than 10 days, and the service cycle of the die lip of a 12-micron product is more than 7 days), but also improves the cleanliness in a workshop and reduces the occurrence rate of white-point defects of the product; effectively improves the time utilization rate and reduces the cost.
