Description

Feeding device and spraying system

Technical Field

The invention belongs to the technical field of spraying equipment, and particularly relates to a feeding device and a spraying system.

Background

The packaging of the commodities is a very important link in the commodity sales and circulation, namely, the exquisite commodities are matched with exquisite packages, and the exquisite packages can arouse the consumption enthusiasm of consumers. For example, high-end items such as watches and jewelry are provided with an elegant wooden outer package. Furthermore, in the production process of these outsourcing, the painting (painting) of the surface of the outsourcing is involved, and the painting operation is usually performed in a flow line manner, that is, the workpiece to be painted is placed on a feeding bracket of a feeding device, and then the workpiece on the bracket is fed into the operation area of the spray gun by the feeding device for painting; however, the prior art spraying system has the problems of low spraying efficiency or high manufacturing cost, which further increases the spraying cost of the workpiece. Specifically, a large part of workpieces participating in a spraying operation link are rectangular, such as rectangular or cube-shaped packaging boxes, four surfaces of the packaging boxes need to be horizontally rotated four times in the process of spraying the packaging boxes (at least three times of rotation is needed, the first state that the workpieces are conveyed into a spraying area along with a conveying chain corresponds to one of the four side surfaces of the workpieces, a spray gun can directly spray the workpieces at the moment, the four side surfaces of the workpieces can be completely covered only by driving the workpieces to rotate three times, and after a certain inclination angle is formed between the spray gun assembly and the workpieces for packaging with a relatively small volume, spraying coverage on the top surfaces and the four side surfaces of the workpieces can be formed after the workpieces rotate four times) so that the spray gun can conveniently form spraying coverage on the side surfaces, the tops and the bottoms of the packaging boxes. In the prior art, on one hand, the workpiece is rotated and sprayed manually, and on the other hand, the spraying efficiency is low, and the spraying quality of the manually sprayed workpiece cannot be guaranteed. On the other hand, the workpiece is controlled to rotate in a mode that the spraying surface of the workpiece is adjusted through the rotation of the stepping motor, or the surface of the workpiece is sprayed and covered through the rotation of the multi-shaft spray gun relative to the workpiece; furthermore, the spraying operation of the workpiece is usually performed in a flow line manner, so that a plurality of feeding brackets are arranged on a conveying chain of the feeding device (for example, 8 workpieces can be sprayed at a time in a spraying area), at this time, in order to ensure that the feeding brackets can drive the workpieces to rotate relative to the spray gun to-be-sprayed surfaces, a servo motor needs to be respectively equipped for each feeding jig, which undoubtedly greatly increases the manufacturing cost of the feeding device or the spraying system, and the control difficulty, and simultaneously, the power supply of the servo motor and the arrangement of signal cables are relatively difficult; when a multi-shaft spray gun is used, the spray gun is used for controlling the rotation of the spray nozzle relative to the workpiece to realize the spraying operation on the four sides of the workpiece, but the spraying efficiency of the multi-shaft spray gun cannot be effectively improved, namely the direction of the spray gun needs to be adjusted between two adjacent workpieces, or a reciprocating spraying stroke needs to be increased, and the manufacturing cost of the spraying system is greatly increased by the multi-shaft spray gun.
