Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bolt production and manufacturing, in particular to a bolt rod coating device and a coating method. BACKGROUND

[0002] During the production process, bolts often need to be coated with lubricants, high polymer materials and other liquids on the rod part; the commonly used technical means at present is manual coating on the rod part, which requires a large amount of manpower, and the coating is not complete during the drying process.

[0003] Another way is to use machine equipment to coat and dry as a whole, which will coat unnecessary parts with paint. For example, the contrast file with the publication number CN213644678U discloses an environmentally friendly and efficient bolt coating device for steel structure building field, which specifically relates to the technical field of steel structure building, and comprises a mounting frame, a base and a workbench. Four corners of the bottom end of the base are respectively fixedly connected with supporting legs. The top end of the workbench is provided with a sliding structure. The top end of the base is fixedly connected with the mounting frame. One side of the top end of the mounting frame inside is provided with a drying mechanism. One side of the mounting frame is fixedly connected with a liquid storage tank. One side of the top end of the liquid storage tank is fixedly connected with a liquid delivery pipe. When the coating work starts, the bolt is placed in the reserved position inside the sliding structure. The switch of the water pump on the control panel is turned on. The water pump starts to draw out the coating liquid in the liquid storage tank through the liquid delivery pipe and deliver it into the connecting hose. Finally, the coating liquid is introduced into the liquid storage tank through the connecting hose. The coating liquid is sprayed on the surface of the bolt through the multiple groups of spray pipes arranged uniformly at the bottom end of the liquid storage tank. At the same time, the switch of the servo motor in the adjusting mechanism on the control panel is turned on. The servo motor is powered on through the output shaft to drive the screw to rotate. The rotation of the screw makes the mounting seat connected with it move left and right on the screw, driving the left and right movement of the fixed column, the liquid storage tank and the spray pipe fixedly connected to the bottom end of the mounting seat, and uniformly spraying the surface of the bolt back and forth. The device uses multiple groups of spray pipes arranged uniformly at the bottom end of the liquid storage tank to spray and coat the bolt as a whole, which not only wastes a lot of paint, but also causes quality or environmental problems in the subsequent process due to the extra paint.
