Oil point equipment and spraying method for plastic products

Abstract

The invention discloses an oil spotting equipment and a spraying method for plastic products using the oil spotting equipment. The oil spotting equipment includes a syringe, a stirrer, a gas pipe, an air pressure supply device and a control device. The stirrer includes a stirring member and a stirring The driving mechanism, one end of the air tube is connected to the air pressure supply device, the other end of the air tube corresponds to the syringe, and the air pressure supply device compresses the air in the syringe through the air tube to control the oil. The invention also discloses a method for spraying plastic products using oil point equipment, including: using oil point equipment to fill the sinking micro metal insert with oil, the oil is not higher than the appearance surface of the plastic product; Dry the oil; spray the plastic products; completely remove the oil on the plastic products that have been sprayed. The invention can completely cover the sinking miniature metal inserts on the plastic products, effectively guarantees the yield and efficiency of the operation, and has the capability of mass production.

Description

technical field [0001] The invention relates to the technical field of plastic product spraying, in particular to an oil spotting device which can be used for plastic product spraying and a plastic product spraying method. Background technique [0002] At present, in the technical field of plastic product spraying, if the plastic product has exposed metal inserts, the metal inserts will be covered before spraying to take advantage of the smooth progress of spraying and avoid affecting the metal inserts. The existing shielding method is usually covered by a mylar, but using a mylar to cover a metal insert, when the size of the metal insert is small (such as image 3 As shown in the miniature copper nails), it will bring the following problems: when the mylar is applied manually, the yield and efficiency are difficult to be guaranteed, and it is not mass-producible; when the mylar is automatically attached, due to the problem of precision , The metal insert and Mylar cannot be...

Problems solved by technology

The existing shielding method is usually covered by a mylar, but using a mylar to cover a metal insert, when the size of the metal insert is small (such as image 3 As shown in the miniature copper nails), it will bring the following problems: when the mylar is applied manually, the yield and efficiency are difficult to be guaranteed, and it is not mass-producible; when the mylar is automatically attached, due to the problem of precision , the metal insert and Mylar cannot be fully bonded, which makes it difficult to guarantee the yield and efficiency, and it is also not suitable for mass production.
