About the disadvantages of nailed cartons and protective goods

The main equipment of the nail-bonding method is the nail box machine. Look at the main defects of the nail box machine.
1. Most carton machinery factories still have no uniform standards for nail containers. For example, SXD120 and Dx48 both show double inclined nail box machines with a nail box length of 1200mm. The former uses three first Chinese Pinyin letters and main specifications for related Chinese characters. One-tenth indicates that the latter is represented by two letters and inches, which causes troubles for the user to use in shape management.
2. Two-speed transmission. The current nail box machine adopts single-stage or double-stage V-belt transmission power, and only one kind of speed ratio with the motor. When the staple carton needs different speeds, the staple box cannot adapt well.
3. The supporting motor is generally around 0.5 KW. Relatively speaking, the power is too large and it is an energy waste.
4. The nail box must repeat the same, monotonous action many times, and the labor intensity is high and the production efficiency is low.
5. Due to different equipment models and internal structures, the heads cannot be interchanged. (Sometimes the same kind of head of the same factory can not be interchanged) This is not conducive to maintenance.
6. The gap between the nose and the felt determines the thickness of the nailable board. As the nail thickness can not be changed, the cardboard will have to go completely thin, and the cardboard will be slightly thicker and “more than enough”, which will significantly affect the quality and speed of the nail box.
7. The names and functions of different model parts are the same, which also brings a lot of inconvenience for maintenance.
8. The feed material is mostly bearing cooperating gears, plus the top wire adjustment method, which is prone to poor feeding.
Let’s take a look at the defects caused by the staple box machine:
1. With a nail carton for a long time, the outside easy to rust, affecting the appearance of the carton appearance, reduce the added value of goods.
2. With a nail carton for a long time, the inner surface is prone to rust and it is easy to contaminate the loaded goods.
3. Nailed cartons are made of metal because they are nails, which can easily damage the loaded goods.
4. The nailed carton is connected with several nails due to the contact surface, the structural strength is greatly reduced, and the body is unstable. It is easy to open the box when the goods are heavy, and claims arising from the damage of loose goods frequently occur.
5. With a nail carton due to the connection of metal objects, the cost of the carton is relatively increased, and there is no advantage in price competition. 6. The nailed cartons are subject to the export regulations of the European Union, Japan, and the United States.
7. There are many problems in the recycling process with nailed cartons that do not meet the requirements of today's green packaging regulations.
In addition, no matter how different the form of the nail box machine is, it is composed of several parts such as the head, the body, the support arm, and the transmission clutch, and the key part is the head. We may wish to use the nose again as a research object.
The most important part in the machine head is the punch. With the punch reciprocating up and down, a working cycle (including shearing) of pressing, punching and dangling is completed in a very short time (about half a second), due to the structure Different design speeds, accelerations and dwell times require different time and delicate parts. This poses some difficulties for manufacturers.
The punch reciprocating mechanism now has three forms of cam, eccentric and eccentric shaft. Cam type is also known as slot wheel type, the disadvantage is that machining is slightly more difficult, the head of the component parts are relatively more, although some of the air damage is less material, but also must choose the steel, the corresponding heat treatment process to improve endurance, extend the use life. The other two kinds of defects are due to the small neck, and the shaft head is subjected to a large impact force during driving, which easily causes the shaft or connecting rod to break.
It can be seen that the three forms of punch reciprocating mechanism are not ideal.
At this point, many drawbacks of the nail box machine plagued the carton enterprises and end users, the pattern of internal and external problems makes the nail box machine's prospects bleak, and its fate is difficult and uncertain. In a large number of surveys by experts, scholars, and colleagues in the packaging industry and end-users, it was unanimously agreed that the staple-free carton was the inevitable trend of future development. This undoubtedly added a weight to the quiet nail box machine. The birth of the box machine made the industry people see new hopes. Compared with the nail box machine, the box machine not only greatly reduced the labor intensity, but also improved the labor efficiency and meet the requirements of the current green environmental protection regulations. The emergence of the box machine has successfully driven science and technology into productivity.
