Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

An oiling device of a lap former capable of preventing oil mist pollution is disclosed, as shown in figures 1-2, and comprises an upper oil injector 4 for injecting oil to the surface of an upper layer aluminum foil 2 and a lower oil injector 5 for injecting oil to the surface of a lower layer aluminum foil 3, wherein the upper oil injector 4 and the lower oil injector 5 are arranged along the width direction of the aluminum foil. The upper layer aluminum foil 2 and the lower layer aluminum foil 3 are tensioned by a plurality of tensioning rollers 1 and move to one side of the winding roller. The upper oil sprayer 4 and the lower oil sprayer 5 are respectively provided with a plurality of oil spray heads which are linearly arranged and used for spraying oil mist to the surface of the aluminum foil so as to obtain a uniform oil film on the surface of the aluminum foil.

In order to solve the problems in the background art, a square surrounding plate 6 is arranged between an upper layer aluminum foil 2 and a lower layer aluminum foil 3, the upper end face and the lower end face of the square surrounding plate 6 respectively keep a 10mm gap with the upper layer aluminum foil 2 and the lower layer aluminum foil 3, and an upper oil injector 4 and a lower oil injector 5 are positioned in the square surrounding plate 6. The function of the square surrounding plate 6 is to isolate the oil mist sprayed by the upper oil injector 4 and the lower oil injector 5 from the surrounding environment.

A partition plate 7 is arranged in the square enclosing plate 6, and the square enclosing plate 6 is divided into an upper cavity and a lower cavity by the partition plate 7. The baffle 7 is in the shape of a ridge with high middle and two side bottoms observed in the width direction of the aluminum foil, and an oil collecting tank and an oil discharge pipe are arranged on the lower side part. The partition plate 7 has the functions of preventing oil mist from the upper oil injector 4 from falling on the surface of the lower-layer aluminum foil 3 to cause the excessive thickness of an oil film on the surface of the lower-layer aluminum foil 3; and secondly, oil drops condensed on the upper oil injector 4 are prevented from falling on the surface of the lower aluminum foil 3, so that the oil film on the surface of the lower aluminum foil 3 is prevented from being uneven. Design into the ridge shape with baffle 7, be favorable to falling on the oil mist or oil drip on baffle 7 can flow into in the collecting vat to obtain retrieving through the oil drain pipe.

Because the square bounding wall 6 can not contact with the upper layer aluminum foil 2 and the lower layer aluminum foil 3 to form a closed cavity, the oil mist can overflow from the gaps at the upper end and the lower end of the square bounding wall 6 to pollute the environment. For this purpose, two air exhaust pipes 8 are arranged on the square bounding wall 6, and the two air exhaust pipes 8 are respectively arranged on two sides of the square bounding wall 6 along the width direction of the aluminum foil. The air inlet end of the air exhaust pipe 8 is communicated with the upper cavity and the lower cavity, and the air outlet end is communicated with an exhaust fan (not shown in the figure). Under the effect of air exhauster, form negative pressure environment in square bounding wall 6, in outside air can get into square bounding wall 6, and the oil mist can not spill over from the gap of square bounding wall 6 upper and lower extreme, can only follow the air admission exhaust tube 8 in.

An electrostatic demister 9 is arranged in the exhaust pipe 8, and a ring groove for collecting oil is arranged in the exhaust pipe 8. The principle of the electrostatic demister 9 is that a strong electric field is formed between a corona wire (cathode) and an oil mist trapping polar plate (anode), so that air molecules are ionized to instantly generate a large amount of positive and negative ions, and the electrons and the ions perform directional movement under the action of the electric field force to form a medium for trapping oil mist. Meanwhile, the oil mist is also charged by the strong electric field, and the charged oil mist performs directional movement under the action of the electric field force and is collected on the oil mist collecting polar plate. The charged oil mist then releases the charged charge and flows into the ring grooves under the influence of gravity. Thus, the purpose of absorbing the oil mist and preventing the oil mist from overflowing to pollute the environment is achieved.

The present invention is not described in detail in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
