A fully automatic nail head mechanism

Abstract

The invention discloses a full-automatic nail head mechanism comprising a servo motor, a transmission gear, a forming machine mechanism, a nailing mechanism, a nail forming block mechanism and a swing arm. The forming machine mechanism comprises a forming machine crank, a forming machine connection rod, a forming machine sizing block and a forming machine sliding block; and the nailing mechanism comprises a first planet carrier, a first gear ring, a first planet gear, a nail forming head connection rod, a nail forming head, a nailing head, a nailing head connection rod, a second gear ring, a second planet gear and a second planet carrier. According to the full-automatic nail head mechanism, by controlling the parameters of the gear ratio of the planet gears to the gear rings, the length of the planet carriers, the length of the nail forming head and the nailing head connection rod, the length of the forming machine crank and the length of the forming machine connection rod, the full-automatic nail head structure suitable for nail wire nail forming, nail conveying and nailing can be obtained, the nail head can achieve persistent and continuous nailing of a carton box, the work efficiency is guaranteed, and meanwhile because nails and the carton box have the same horizontal speed, and the nailing quality can be guaranteed during box nailing.

Description

technical field [0001] The invention relates to the field of corrugated carton packaging machinery, in particular to a fully automatic nail head mechanism. Background technique [0002] The mechanization of nail boxes is one of the development trends of nail box machinery. The mechanization of nail boxes has the characteristics of reliable quality, high production efficiency and less labor force, and its economic and social benefits are very considerable. The nail head is an important part of the nail box machine, and its main functions are nail forming, nail feeding and nailing. The currently used nail heads include cam-type semi-automatic nail heads, connecting rod-type semi-automatic nail heads and connecting-rod-type automatic nail heads. The cam-type semi-automatic nail head is mainly used in the early manual nail box machine and semi-auto nail box machine. The nail head and the nail head are respectively controlled by two grooved cams to complete the nail forming, fee...

AI Technical Summary

Problems solved by technology

The cam-type semi-automatic nail head is mainly used in the early manual nail box machine and semi-auto nail box machine. The two grooved cams are used to control the action of the nail head and the nail head respectively to complete the nail forming, feeding and nailing. The highest speed It can reach 300-400 nails per minute. The advantages of cam-type semi-automatic nail head are simple structure, reliable operation and convenient maintenance. The disadvantage is that the cam wears seriously at high speed, which requires higher hardness and precision of the cam, and the processing technology is more complicated.

The connecting rod semi-automatic nail head is developed on the basis of the cam type semi-automatic nail head. Now it is widely used in manual box nailing machine, semi-automatic nail box machine and automatic nail box machine. The nail head passes through a pair of eccentric cranks. Control to complete nail forming, nail feeding and nailing. The highest speed can reach 500-600 nails per minute. The advantages of the connecting rod semi-automatic nail head are simple processing, high-speed stability, and the disadvantage is that compared with the cam-type semi-automatic nail head principle and structure is complex

The connecting rod type automatic nail head, also known as the swing nail head, is a nailing method gradually developed in recent years. The nail head realizes the forming and delivery of the nail head in motion through a series of linkage mechanisms. Nails and nails, compared with semi-automatic nail heads, fully automatic nail heads can realize paper non-stop nailing, which greatly improves the efficiency of the nail box machine, and the nailing speed can reach 1000-1200 nails / minute, but due to the linkage The nail head is composed of a large number of connecting rod mechanisms, which leads to poor stability of the nail head when used at high speed. In order to improve the stability, the processing and assembly precision of the parts must be improved. As a result, this technology is only mastered by a few companies in Europe, resulting in continuous Rod full automatic nailers are expensive

The semi-automatic nail head needs to stop when nailing the carton, resulting in low production efficiency, which cannot meet the development needs of the automatic nail box machine

The link-type fully automatic nail head has high automation efficiency, but because of its complex structure, high cost and high maintenance cost, it is difficult to popularize it in China. This requires the development of a new nail head mechanism, which can be used in motion. Complete the forming, feeding and driving of nails. At the same time, the mechanism is required to be simple in structure, stable and reliable, easy to process and easy to maintain.
