Background
In order to improve the appearance quality and the service life of the engine, the engine is usually required to be purposefully and purposefully sprayed with paint before leaving the factory. The engine paint spraying is different according to the needs of customers, but all the water oil ports, the processing surface, the nameplate and special parts such as the induction plug and the like on a normal engine are not required or even can not be sprayed, and at the moment, certain parts are required to be used for shielding the parts or special parts which do not need to be sprayed before the paint spraying so as to avoid the pollution caused by the paint during the paint spraying. The engine oil filter is one of special parts, and is required to be shielded when an engine is sprayed with paint because of maintenance and other requirements on the engine filter so as not to influence maintenance and use of the engine by a customer. The current conventional oil filter shielding is to shield the whole oil filter Bao Long by using a shielding plastic bag, and then bundling and wrapping the plastic bag. Even a plurality of shielding plastic bags are needed under special conditions, the shielding plastic bags can only be used as a waste after each paint spraying, and a new engine is continuously shielded by the new shielding plastic bags. The shielding method of the engine oil filter can not be effectively recycled, the plastic bag is consumed more, the consumed cost value is high, the plastic bag is used for shielding, and the waste plastic bag can cause secondary pollution to the ecological environment.
Besides, in the prior art, a shielding device which can be recycled is made into a pocket-shaped structure by adopting a cloth material, a framework is arranged in the shielding device, a fastening rope is arranged at the pocket opening, the shielding device is sleeved on the engine oil filter when in use, the pocket opening is fastened by the fastening rope, and the framework in the shielding device supports the shielding device to prevent the engine oil filter from being damaged by collision. The shielding device is relatively troublesome to assemble and disassemble, the manufacturing cost is high, and cleaning liquid is not easy to clean.
The prior oil filter shielding tool mainly has the following two defects: 1. and cannot be reused. After the shielding plastic bag is sleeved with the engine oil filter for spraying paint, the plastic bag is stained with paint and can only be used as a waste, and the engine oil filter of one engine at least needs one shielding plastic bag. 2. The disposal of the waste plastic bags causes secondary pollution to ecology. The plastic bag is mainly made of nitrocellulose, the difficulty of natural degradation is very high, and the buried underground can pollute the ground. 3. The assembly and disassembly are relatively labor-consuming and not cleaned. At present, the common treatment mode is combustion, but the harmful gas generated by the combustion of the plastic bag forms secondary pollution to the ecological environment.
